DESC:FIELD OF THE INVENTION
The present invention relates the development of an indigenous embedded operating platform for remote use by a trained medical practitioner for detection and tele-consultation of medical disorders. More specifically, it discloses a remote embedded platform for diagnostic devices, operated by the ophthalmologist situated in a remote location, by means of a master control unit and an Electronic or virtual joystick based with the said master control unit.

BACKGROUND OF THE INVENTION
According to the Rural Health Statistics for the year 2021-22, there are about 5,480 community health centers and 24,935 primary health care centers in rural India, which are equipped with 34,125 specialists. These medical officers specialize in different fields of medicine and surgery, ophthalmology being one such field. Although the number of health facilities in rural areas of India have increased during the past decade, convincing doctors to work in them remains a challenge. Overall, there is a combined shortfall of about 18,211 specialists in the primary health centers and community health centers in rural areas of the country.

Given the relatively small number of qualified ophthalmologists, appointing them in all health care centers is neither practical nor feasible, besides becoming counterproductive. Moreover, rural health-care centers are not equipped with state-of-the-art ophthalmological diagnostic devices.

The shortfall of trained ophthalmologists and necessary infrastructure essentially requires physically transporting the patients from rural to urban hospitals for diagnosis and treatment. This increases the cost of diagnosis, treatment, and patient care in the rural set-up.
Given the high cost of travelling to far away health clinics and hospitals for specialized treatment, rural communities preferably rely on informal rural medical practitioners to provide basic health services, medical advice, and support. However, this may not be feasible in case of advanced medical conditions like cataract, glaucoma etc., which require urgent attention by ophthalmologist located in areas far away from the patient.

Telediagnosis and tele-medicine have been adopted in recent times to mitigate the disadvantages of lack of specialized medical practitioners in rural areas. They offer an opportunity for effective collaboration of primary and secondary health care setups and to reach population staying in underserved areas.

“Telediagnosis” refers to remote diagnosis wherein platforms are designed to enable transmission of physical examination records and medical reports remotely or concurrently to a specialist.

“Telemedicine” refers to the use of technology to deliver clinical care at a distance. It ensures that a person receives healthcare when needed, especially for those with limited access to care, like patients in rural areas. Telemedicine delivers health care by virtue of exchange of data, information and use of telecommunication technology. Thus, telemedicine is prudent for effective remote communication of information to facilitate clinical care.

However, the telediagnosis and telemedicine infrastructure in rural areas is still in the nascent stage. Lack of appropriate telemedicine platforms and specialized personnel prevents the use of technology to its full potential. Remote diagnosis still requires personnel with certain skills in the patient's location to ascertain clinical information from the patient which can be transmitted to the specialist in remote location for efficient diagnosis. Consequently, there exists a crucial gap between public health services and needy population. which restricts the critical patients from getting urgent valuable medical advice and treatment from trained medical practitioners placed in remote locations, far away from rural areas.

Eye disorders like cataract and glaucoma require urgent diagnosis and medical care to prevent further damage to the eye. Adopting telediagnosis and telemedicine platforms to cater to the requirements of rural population entails efficient image capture of the eyes of the patient which is then transmitted to a remotely located ophthalmologist for diagnosis and treatment.

However, remote diagnosis still requires personnel with certain skills in the patient's location to ascertain clinical information from the patient such as visual acuity, intraocular pressure, and retinal images, by using ophthalmological diagnostic devices. A shortage of such skilled personnel in rural areas makes it difficult to ascertain the said clinical information accurately, which may lead to misdiagnosis and eventual wrong treatment.

As a result of the above limitations, there is a need for an ophthalmological diagnostic and treatment platform wherein all the ophthalmological diagnostic devices can be mounted thus enabling remote operation of such devices by a trained ophthalmologist. Such a platform is required to facilitate tele-diagnosis of ophthalmological disorders by trained ophthalmologists for patients situated in remote rural locations.

Patent application no. JPH08191794A entitled “Optometry System Having Remote-Control Device” discloses a system to control plural devices included in an optometry system, by receiving a signal from a remote-control device by means of a signal receiving part of a specified device and by sequentially controlling motions of the other device according to a received signal by means of a signal processing part. However, in such a system, the devices are connected to one another, and one device is controlling the other. The system is not used for telediagnosis.

Another patent application no. JP-H0614881 titled “Remote Manipulator for Ophthalmoscopy” discloses a remote manipulator for ophthalmoscopy which can increase the number of switchable targets and improves the indicating ability of targets used for the ophthalmoscopy. The system constitutes a remote manipulator for ophthalmoscopy to switch the display of various targets or target groups for ophthalmoscopy by sending a remote manipulation signal to a visual acuity table display device which can display those targets. However, such a system does not allow the specialist to remotely operate the targets.

Another patent application no. IN-201941019785 titled “Portable Robotic Device for the Examination of Human Eye and Method of Operation Thereof” discloses a portable robotic ophthalmological device for the examination of anterior and posterior segments of a human eye. The robotic eye examining device can examine large populations in minimal time; can be detached and attached; and is portable. However, such a system is used for in-person diagnosis and operation rather than in telediagnosis.

OBJECT OF THE INVENTION
In order to obviate the drawbacks of the existing state of the art, the present invention discloses an embedded platform for deploying ophthalmological diagnostic devices, which enables remote detection of ophthalmological disorders of patients in rural areas and in rural health care centers itself, without the need of a skilled ophthalmologist.

The main object of the present invention is to provide an indigenous remote embedded operating platform for ophthalmological diagnostic devices, enabled with an electronic or virtual joystick based with master control unit over remote mode or smart tele-diagnosis.

Another object of the invention is to provide an indigenous remote embedded platform for rural areas wherein the ophthalmological diagnostic devices are digitally connected to urban hospitals via an internet platform.

Yet another object of the invention is to provide a digitally connected indigenous remote embedded platform for diagnostic devices enabling a trained ophthalmologist in an urban hospital to diagnose and operate a patient in any rural health care center by means of an electronic or virtual joystick based with master control unit over remote mode or smart tele-diagnosis,

Yet another object of the invention is to provide an indigenous remote embedded platform for ophthalmological diagnostic devices, in which the operating platform is equipped with motorized X, Y and Z translation using appropriate stepper motors and drives controlled over remote operation.

SUMMARY OF THE INVENTION
Accordingly, the present invention relates to an indigenous remote embedded platform for ophthalmological diagnostic devices which enables diagnosis of ophthalmological disorders of patients in rural area and in rural care centers itself without the need of a skilled ophthalmologist. The remote embedded operating platform is used to mount the ophthalmological diagnostic devices including Fundus Imaging devices, Refractometers, Slit Lamps, Tonometer, and similar other devices.

The indigenous remote embedded operating platform as disclosed in the present invention enables the mounting of any ophthalmological diagnosing device in any rural care center. The platform is digitally connected to urban hospitals via an internet platform. This method of digitization enables a trained ophthalmologist in urban hospital to detect the eye disorders of patients in any rural hospitals over remote mode or smart tele-diagnosis.

The model of the remote embedded operating platform is based on three essential components:
- a standalone operating platform for mounting ophthalmological diagnosing device, the operating platform is equipped with motorized X, Y and Z translation using appropriate stepper motors and drives. These stepper motors are controlled from distance mode over remote operation.
- electronic or virtual joystick base with master control unit for remote operation, and
- a standalone operating system for signal, image communication and synchronization.
Essentially, the remote embedded operating platform has three major operational modules, wherein it is operated via remote mode for capturing the best image of the eye to enable the ophthalmologist to detect the eye condition of the patient correctly. This entails communication between the user end module and the operating end module by signal transmission between the two modules without any time delay.

The remotely situated ophthalmologist uses an electronic joystick to create focus on the region of interest of the eye. Once the focusing module of the device is properly focused on the appropriate portion of the eye (either the cornea or the retina), an image of the eye is captured. Subsequently, the captured image is available on the screen of the diagnosing device and this image is directly shared to the operating end via screen sharing mode. The ophthalmologist detects the eye condition of the patient based on the captured image.

For appropriate working of the remote embedded operating platform, optimization of image transportation between the devices, voice communication between the doctors at the two ends for smooth communication and a high-speed internet platform that connects the devices between the ends (modules) is required.

The remote operation of the platform essentially avoids physical transportation of patients from rural to urban for quality detection and treatment of eye disorders. Since diagnosing devices mounted on the platform in primary health care centers are controlled and operated by trained experts over remote mode, any medical officer (need not be an ophthalmologist) can assist during diagnosing process at the patient end.
The model enables quality diagnosis and treatment for a large population with a minimal number of technical or trained expertise, that too within the rural primary health centers devoid of eye specialists. This will facilitate the percolation of the technology to the entire community at minimal cost. Moreover, the tele – diagnosis feature of the model provides early diagnosis for critical ophthalmological disorders such as Glaucoma which require urgent attention and do not have permanent cure. It saves time and costs thus minimizing the harmful effects of these conditions through early diagnosis.

DETAILED DESCRIPTION OF THE INVENTION:
‘Ophthalmological diagnosing devices’ are instruments used by ophthalmologists and optometrists to examine and diagnose eye conditions, including devices like slit lamps, tonometer, fundus cameras, optical coherence tomography (OCT), and visual field perimeters. These devices enable detailed and accurate assessments of eye health, aiding in the diagnosis and monitoring of various conditions, including glaucoma, retinal diseases, and neurological disorders, even during their early stages.

In hospitals, all ophthalmological diagnosing devices currently being used are mounted on an operating platform which is operated by a mechanical joystick to focus the camera module on the region of interest in the human eye. A ‘joystick’ is a pointing and controlling device that is commonly used for controlling and moving required objects on the system screen. With respect to machine operations, joysticks are a controlling tool that is used to move items at different angles or through operational processes as per requirements inside a machine. A joystick comprises a base and a stick that can be moved left and right at any angle in the process. While some joysticks are integrated into the system's keyboards, others are standalone devices. The Joystick essentially drives the device along three orthogonal axis such as “X”, “Y” and “Z” directions. Thus, this focus is the only manual operation during diagnosis but is extremely critical as it essentially demands a trained ophthalmologist.

An ‘embedded system’ is a combination of computer hardware and software designed for a specific function. These systems are either programmable or have a fixed functionality. Embedded systems are low-cost, low-power-consuming, small computers that are embedded in other mechanical or electrical systems. Embedded systems comprise of hardware, software and real-time operating systems.

The present invention discloses an indigenous remote embedded operating platform (OP) for ophthalmological diagnostic devices by facilitating the mounting of said ophthalmological diagnostic devices including Fundus Imaging devices, Refractometers, Slit Lamps, Tonometer, and similar other devices to enable diagnosis of ophthalmological disorders without the need of a skilled ophthalmologist.

While the invention has been disclosed with reference to certain embodiments, it will be understood by those skilled in the art that various changes may be made, and equivalents may be substituted without departing from the scope of the invention. In addition, many modifications may be made to adapt to a particular situation or material to the teachings of the invention without departing from its scope.

Throughout the specification and claims, the following terms take the meanings explicitly associated herein unless the context clearly dictates otherwise. The meaning of “a”, “an”, and “the” include plural references. Additionally, a reference to the singular includes a reference to the plural unless otherwise stated or inconsistent with the disclosure herein.

Essentially, the system of the remote embedded operating platform (OP) of the invention has three major operational modules (depicted in Fig.1), namely:
a) A motorized operational platform (OP) on which any diagnosing device may be attached, this device being retained in rural care center where patient is sitting in which the diagnosing device is connected to ophthalmologist in the operating end via internet. This end of the system is referred to as user end. Thus, this platform serves as the user-end module (UEM).
b) An operating module consists of either an electronic or virtual joystick (JS) interfaced with a computer. This setup is given to the ophthalmologist who is sitting and operating the device by using electronic joystick (JS)in any urban hospital and is referred to as an operating end. Thus, this platform (P) is the operating-end module (OEM).
c) Interface of the user end (UEM) and operating end modules (OEM) via internet platform for remote or tele-operation.

The trained ophthalmologist at the operating end is provided with an operating unit that includes a computer and a joystick. The computer screen is divided into three sections. One section displays a background video (as shown in Fig. 1), which tracks the movement of the user-end module or platform along the X, Y, and Z axes based on joystick controls. This assists the operator in aligning the patient’s eye.
The second section shows a real-time retinal or eye image. Once the focus is adjusted, the targeted region of the eye becomes visible in this section. The third section is dedicated to control functions such as zooming in and out, capturing images, and recording videos.

The joystick movements along specified axes are converted into digital signals and transmitted to the cloud. Simultaneously, the background video and eye images received by the operating unit are displayed as live video on the computer screen. The joystick data transmission from the operating end and the reception of video feeds from the patient’s end occur in parallel, ensuring synchronized control. Two separate communication channels are used for this process.

At the patient’s end, the platform moves along the X, Y, and Z axes in response to joystick signals received via the cloud. The patient remains seated without movement, with their face stabilized using a chin rest for accurate diagnosis, as illustrated in Fig. 1.

The hardware components of the system include sensors, analog-to-digital (A-D) converters, processors, digital-to-analog (D-A) converters and actuators. The embedded system uses communication ports to transmit data between the processor and peripheral devices using a communication protocol. The processor interprets this data with the help of minimal software stored on the memory, wherein the software is usually highly specific to the function that the embedded system serves.

The working of remote embedded operating platform is based on three essential components which comprise of:
a) a standalone operating platform (OP) for mounting ophthalmological diagnosing device, the operating platform is equipped with motorized X, Y and Z translation using appropriate stepper motors and drives. These stepper motors are controlled from distance mode over remote operation.
b) an electronic or virtual joystick (JS) base with master control unit for remote operation, and
c) a standalone operating system for signal, image communication and synchronization.

The remote embedded operating platform (OP) is capable of moving along two horizontal left and right denoted as “X” direction, front and back denoted as “Y” direction and a vertical upward and downward direction denoted as “Z direction. A payload mount which is essentially a fundus camera mount is provided on the motorized platform (P). In the mechanical architecture of motorized platform (P), as depicted in Fig. 2, both the “X” and “Z” modules are separately operated or driven by a stepper motor (SM) providing torque of 10 Kg cm, operated by 12V and 2.3A power supply. Each of these stepper motors provide 180 full steps as well as micro steps for minute movement to enable precise diagnosis. Here X axis motor depicts the X module along the X axis, whose range is controlled by the corresponding X- axis signal received from the joystick and vice versa for other two axis.

The “Y” directional movement, which is essentially used to move the device or payload towards the patients’ eye, is embedded with a stepper motor (SM) providing a torque of 7.5 Kg cm, operated by two phase, 12V and 2.3 A power supply. This stepper motor (SM) also provides 180 full steps as well as micro steps for minute movement for precise diagnosis. The three stepper motors (SM) move the platform 150 mm along the specified “X” axis, 100 mm along the specified “Y” axis and 50 mm along the specified “Z” axis respectively.

The maximal and minimal distance movement along the three directions are controlled by two limiting switches along each direction for a precise and safe operation.

All the three stepper motors (SM) are connected to at least single Raspberry -pi processors through three separate driver units. The signal received by Raspberry- pi from the operating end or joystick (JS) over remote is proceeded and delivered to the corresponding stepper motors (SM) through the driver units. All the stepper motors (SM) used in this operation are in NEMA series procured in standard mode. Each driver receives inputs from Raspberry- pi and delivers the signal to the corresponding stepper motors (SM) to enable, operate and control along the specified direction with steps given in the input and limit the distance movement. These drivers work with pulse width modulation (PWM) signal. The system architecture of the user end of the platform is depicted in Fig. 3 and 5 respectively. Here all the three units are not moving simultaneously, thus a single channel is given for all the X, Y and Z axis transmission. Base unit comprises X motors, which move the platform along the required X axis, followed by a Z-axis motor that is fixed to the base unit, and finally, the camera module is moved towards and away (along the Y axis) from the patient's eye.

The Raspberry- pi master processing unit deployed in the system is a Raspberry Pi 5 Model 8GB, packed with a 64-bit quad-core Arm Cortex-A76 processor clocked at 2.4GHz. It delivers a substantial boost in graphics power to 800MHz VideoCore VII GPU, supports dual 4Kp60 display output via HDMI, and offers state-of-the-art camera capabilities with Image Signal Processor.

The Raspberry-pi receives input from internet cloud. The signals are received from three different channels, with one of them corresponding to operation of three stepper motors (SM), the second corresponding to camera control in the payload, which includes camera on-off, image and video capture, digital magnification of images etc. The third channel is temporally left floating which is used to see the background in the diagnosing room to the remote operator, such as the patient, complete diagnostic device, its movement along all three directions, local medical practitioner with the patients and communication between these two practitioners. Any conventional Ip- camera can be connected to the third channel. The whole device is powered by a switchable mode power supply (SMPS) operating at 230 V – 150 W power.

A standard mechanical joystick (JS) (which is mechanically movable along the “X” and “Y” axis and a button to move along “Z” axis) is employed in operating end (front end) to generate signals corresponding to axial movement along the three axis of the joystick (JS) and is transferred to back-end processor as an input through internet cloud. In the joystick (JS), with respect to equilibrium position, left may be taken as positive axis (where the coordinates are represented in positive values) and rightward movement is assigned as negative axis (where the coordinates are represented in negative values). The same movement is considered for the front and backward moment. However, the height movement along upward and downward are assigned to two of the many buttons in the joystick. The movement data of joystick (JS) is depicted in Table 1 below:

Joystick data X:0 and Y:0 given in the above table indicates the data obtained when the joystick (JS) is not moved in any direction. Any positive value of X indicates the data obtained while moving the joystick (JS) along the positive axis and vice versa. Similarly, any negative value of X indicates the data obtained while moving the joystick (JS) along the negative. The same interpretation is applied for the negative and positive Y axis data.

Height movement of the device ends as operated by button control in the joystick (JS) represents integer "1" when movement occurs and "0" when movement does not exist along the height.

Each digit in the square bracket [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0] represent whether the buttons are moving or not. Since the joystick (JS) consists of 12 buttons and only two of them are being used for upward and downward movement the last two digits in the square bracket only vary as 0 or 1, when the device is moved.

A new operating system (OS) has been developed for the entire communication between operating end diagnostic ends. Software operations are classified into two classes, one is a front-end operation which operates the website where joystick (JS) is used for operation. This web page is given as a screen to the operator who operates the joystick wherein the task is coded by using html and JavaScript. The back-end operation works at the processor end. The JavaScript connects the device at the back end essentially implying the data generated at the joystick transferred to backend to enable it to server, Raspberry pi, GPIO motor control and camera operation. Webpage to server linkage generates dynamic links during each operation which is made a static web link for smooth operation by tunneling process (linkage of local Ip address with the backend Ip).

Back-end operation is coded by using Python language in Micro dot platform. Camera operations such as image and video streaming are operated and coded by Open-CV platform. Further, gRPC Remote Procedure Calls basically called gRPC is the employed form of video and image streaming for negligible latencies.
