DESC:FIELD OF INVENTION:
[0001] The present invention relates to the measurement of pressure pulses of the heart in the radial artery, more particularly the Naadi, as related to ayurvedic diagonis and treatment. The electronics sensors and more specifically, the associated embedded software algorithm not only detect the pressure pulses of the heartbeat at locations in the body wherever it can be felt and transfom the pressure pulses to three Naadis as identified in ayurvedic treatment, display the Naadi in the device itself and also transmit the information through a communication protocol to either an email, to a mobile phone or to a cloud location for later retrieval and analysis.

BACKGROUND OF THE INVENTION:
[0002] To a large extent, ayurvedic treatments till now follow very traditional methods, with a very limited infusion of modern technology. With the advent and advancement of modern technology, electronic devices specifically created for ayurvedic applications can offer excellent help for practicing ayurvedic physicians in accurate diagnosis and better treatment options for patients, based on body type. Though all age groups seek ayurvedic treatment, Children and elderly are the two predominant groups of patients seeking ayurvedic treatment. These two age groups of patients are limited by their age and inability to access ayurvedic physicians at a short notice or after a short travel. Today ayurvedic treatment remains primarily confined to India, though the exposure of ayurveda to the outside world is increasing. In order that humanity can leverage the full benefit of ayurveda, it is important that not only people throughout the world have remote access facilities for consultation with ayurvedic physicians in India but there exists a strong need for basic and important initial evaluation/diagnosis at the patient location, and automatically transmit the data to ayurvedic physicians in India for further review and to come up with better treatment options for the patients. Basic diagnosis that is automated and remotely available can help both patients and physicians.

[0003] Naadi Pariksha or Naadi reading remains central to any diagnosis in Ayurveda and every ayurvedic treatment consists of correction of Vata, Pita and Kapa dosha imbalance. A patient’s Naadi decides the dosage of medicines like how body weight decides the dosage in allopathy. If a patient requires a cocktail of medicines, Naadi of the patient plays a vital role. The outcome of Naadi Pariksha helps fine tune the treatment options for the patient.

[0004] Those patients who can visit an Ayurvedic physician at will can have their Naadi examined by the physician. For those who are unable to access the physicians easily such as those who reside outside of India or at a considerable distance from the physician or if the Naadi Pariksha needs to be done at a specified time of the day, if Naadi Pariksha can be done at their location and the data transmitted to the physician wireless, it will be immensely beneficial to the patients.

[0005] There are several literatures that disclose the methods and systems for Naadi prediction. The scientific literature titled “Remote Medical Alert Monitoring System – Providing Telehealth By Integrating Ayurveda With Sensors And Mobile Computing” discloses a conceptual framework for remote monitoring of medical alerts integrating Ayurveda, wearable sensors, mobile based decision support and cloud services. Extensive literature review and consultation with clinical experts, Ayurveda practitioners and technology specialists working with sensors were carried out to develop the framework. The framework enables the assimilation of vital parameters of registered individuals 24x7 through wearable sensors and detecting anomalies by combining them with Nadi Prakisha to provide timely notification in case of medical emergencies even in remote areas. This will improve timely communication between relevant stakeholders and help in reducing mortality occurring due to lack of timely help.

[0006] Another patent application IN202241029331 proposed a block outline of Nadi Pariksha for beat determination and addresses the progression of illness location. The stream begins with the patient validation for example every one of the subtleties of the patient has been enlisted. After enrollment, beat sensors are joined on the wrist of the patient which are utilized to incorporate the beat signals from the patient. In the wake of gathering information, the information is safely brought for preprocessing on cloud and after pre-handling, the order calculation has been applied for approval.

[0007] Another literature titled “Nadi Tarangini Pressure Sensors” discloses a device records pulse data and generates a comprehensive Nadi report. It works with an Android phone or tablet (not included with the device). An internet connection is necessary to connect to and store visit details on a cloud-based account, access to which is free for the lifetime of the device.

[0008] However, there exists no invention that discloses a device that can be used by both patient and doctor which is compact - capturing the data, storing and displaying it locally, and transmitting it to the cloud using either Wi-Fi or 4G or higher.

OBJECTIVE OF THE INVENTION:
[0009] The main objective of our present invention is to develop a device that is compact, lightweight, hand-held, and has a display screen attached to it wherein the Naadi is displayed and also it transmits the data to a cloud location, from where, through proper registration, physicians, patients and hospitals can access the data to a laptop or to a mobile device for further review, diagnosis and treatment.

[0010] The other feature of our present invention is that it has a flash memory built into it for storage of data and later transmission if WiFi or 4G is not immediately available.

[0011] The other objective of our present invention is to provide a device that can be used both on the left and the right hand of a patient by flipping a switch and can be used at multiple locations on the human body, wherever one could feel the pulse so that the same sensor will read the same prakriti.

[0012] The other objective of our present invention is to display three distinct graphs commensurate with the tridoshas, the Vata, Pita and Kapa. In each one of the graphs for Vata, Pita and Kapa, not only the time sequence (Gati) of pulse but also rate (Vega), rhythm (Tala), and force (Bala) of each one of the Prakritis (Vata, Pita and Kapa) will be displayed. The noise of data is controlled by means of electronic circuitry.

[0013] The other objective of this invention is to make this device a self contained unit with no wired connections to a third device. This device does not require any other equipment for operation. This device operates on a battery which is housed inside the device

DETAILED DESCRIPTION OF THE INVENTION:
[0021] The principles of operation, design configurations and evaluation values in these non-limiting examples can be varied and are merely cited to illustrate at least one embodiment of the invention, without limiting the scope thereof.

[0022] The embodiments disclosed herein can be expressed in different forms and should not be considered as limited to the listed embodiments in the disclosed invention. The various embodiments outlined in the subsequent sections are constructed such that it provides a complete and thorough understanding of the disclosed invention, by clearly describing the scope of the invention, for those skilled in the art.

[0023] Throughout this specification, various indications have been given as to preferred and alternative embodiments of the invention. It should be understood that it is the appended claims, including all equivalents, which are intended to define the spirit and scope of this invention.

[0024] The primary components of this device are three independent sensors (103), a microchip (107), two switches one on either side, a battery, a display window, and a plastic cover for the battery (101), battery cover (102) and all these components are housed inside a plastic housing (105). A whole range of variations of the same concept is possible. What is depicted here are only the basic ones - hand-held compact device the size of which is half that of commercially available mobile phones, yet another possibility is a variation where the sensors (103) are at the opposite side of the display screen (106) which can be placed at the location of the heart of the patient for Naadi reading, a wrist watch type device that can be worn on the wrist of the patient and a clip type device that can be inserted on the patient's hand to ascertain the Naadi. A further and natural extension of this device can be not only to measure the blood pressure of the patient but it can also be used for EKG or ECG measurement of the patient.

[0025] Central to this invention is the microchip (107) with a flash memory, which using embedded software, not only reads the data received by the three independent sensors (103) but also stores it locally in a flash memory and transmits the data to the cloud for later access by authorized people. The three sensors are strategically located in the device to read the Vata, Pita and Kapa parameters of a patient. The transmission protocol uses either 4G or WI-FI. The front of the device has a display screen that displays the data collected by the microchip (107) locally on the device itself. This way, the patient can also view the Naadi instantaneously.

[0026] This device is operated first by turning on the on/off switch (104) so that it is ready to read the data. Then the device should be placed in the body in such a way that the three sensors or the sensor pad touch the wrist of the patient gently at the location where we normally feel the pulse or in the case of the rear mounted sensors (103), the device is placed on or near the location of the heart of the patient. The software is so designed that it would initially ensure that all three sensors read data. If one of the sensors is not picking up data, it will give a warning indicator on the display screen. If a warning indicator appears on the screen, all that needs to be done is to move the device towards the direction of the sensor which is not picking up the data ever so gently till the warning indicator goes off and when there is no warning indicator, it means that all three sensors are reading the data. After placing the sensors at the appropriate location, the device should be turned on so that it starts actively reading the Naadi data from the patient’s wrist or the chest, as the case may be. Since typically the Naadi data is measured on the left hand of a female patient and the right hand of a male patient, the LH/RH switch (108) makes sure that the same sensor reads the same Naadi (either Vata or Kapa). The Pita Naadi is measured by the sensor located at the center. Therefore the LH/RH switch (108) should be at either the LH or RH position depending on if the left hand is used to measure the Naadi or the right hand is used to measure the Naadi.

[0027] The embedded software built into this Pulscraft helps not only temporarily store the data locally in the device in a flash memory but also when the communication protocol is available (WI-FI or 4G), helps transmit the data to a cloud server for storage and later access. The physician or any other authorized person with proper registration with the cloud can access the data and either display it on his laptop or in his mobile device for his review.

[0028] The embedded software built into this device helps not only temporarily store the data locally in the device in flash memory but also when the communication protocol is available (WI-FI or 4G), helps transmit the data to a cloud server for storage and later access. The physician or any other authorized person with proper registration with the cloud can access the data and either display it on his laptop or his mobile device for his review.
[0029] As a first step in using this device, one needs to turn on the device by switching on the ON/OFF button (104). Make sure that depending on which wrist the measurements are made, the appropriate LH/RH switch (108) is turned on. Before placing the device on the wrist, it will be helpful if the hand is placed at the edge of a table in such a way that the wrist is at the edge of the table (so that the hand from elbow to the wrist is supported and the portion after the wrist is not supported). This is done to make sure that the hand is steady and does not move during the measurement. Place the device at the appropriate location of the wrist in such a way that the display screen sensors read the pulse data. If one of the sensors or all of them are not reading the pulse data, a warning message will be displayed on the screen. If a warning message is displayed on the screen, then the position of the device should be adjusted in such a way that the warning light goes off. More often the device needs to be moved linearly either towards the wrist or away from the wrist to make sure that the sensors read the data or in rare cases, the pressure of the device on the hand needs to be increased or decreased. Similar adjustments must be made if the device is used in the ankle or chest or neck. In order to make sure there is no relative motion between the device and the body location when measuring at the ankle or neck, or chest, perhaps one would require help from another individual. Once the device is reading the data correctly, hold the device in its place for 5 seconds approx. Within five seconds, the sensors would have captured the pulse data correctly. After that, the device can be removed from the body. At this time, the display screen will display the three distinct pulse data corresponding to the Vata, Pita, and Kapa doshas.

[0030] When the device is used for the second time, the previous Naadi information will be shown on the screen. There is no need to reset the device. When the sensors read the newer data, they will erase the old one and display the new one automatically.

[0031] The device of the present invention can be used standalone or can be incorporated into any device such as but not limited to a smart watch, mobile, or any wearble device.

[0032] In one of the variants of the device, a provision is given to measure the blood pressure of the patient. This works as follows. The device is initially used as explained above. Once it reads the Naadi information, press the device against the wrist in such a way that no information is read by the sensors (here the sequence is important; first one needs to ensure that the Naadi information is read correctly and without removing the device from the wrist, one needs to press it against the wrist so that the sensors will report that no information is being read. As one slowly relieves the pressure of the device against the wrist, the sensors will pick up the pressure exerted by the arteries the first time which is the diastolic pressure and when it picks up the pressure the second time, it is the systolic pressure. We are working on additional modifications to this device so that this is done automatically without manually pressing the device against the wrist. Both the diastolic and systolic pressures will be displayed on the display screen along with the Naadi data.

[0033] The embedded software built into this Pulscraft helps not only temporarily store the data locally in the device in a flash memory but also when the communication protocol is available (WI-FI or 4G), helps transmit the data to a cloud server for storage and later access. The physician or any other authorized person with proper registration with the cloud can access the data and either display it on his laptop or in his mobile device for his review.

[0034] Figures 1a through 1e show sketches of Pulscraft wherein the sensors are installed opposite side of the display screen. This variation is ideally suited for reading the Naadi data from the chest of a patient.

[0035] Figures 2a through 2e show sketches of Pulscraft wherein the sensors are installed at the bottom of the device. This variation is ideally suited for reading the Naadi data from the wrist or ankle of a patient.

[0036] Figures 3a through 3e show sketches of Pulscraft wherein the device looks L shaped and the sensors are installed below the L portion of the device. On the top of the L portion of the device is a pressing pad, which when pressed against the body of the patient will temporarily stop the blood flow and slowly release the pressure so that both diastolic and systolic blood pressures can be recorded by the sensors. The release of the sensors after being pressed against the body of the patient is done by a spring mechanism at a very slow rate (this is not shown in these sketches)

[0037] Figures 4a through 4e show sketches of Pulscraft which are designed as a wristwatch, which when worn by the patient and tightened by the strap will measure the Naadi. This can be worn for a long time for continuous monitoring of Naadi or Blood Pressure.

[0038] Figures 5a through 5e show sketches of Pulscraft which is designed as a clip which when inserted on the wrist of ankle area of the patient can measure the Naadi. An additional pressing pad will help measure blood pressure of the patient as well.

[0039] Furthermore, in the future, the device can also be implemented using a single, high-precision sensor, such as a photoplethysmogram (PPG), to read heart pulses and transform this data into Naadi information. Advanced signal processing algorithms filter the raw data, and enhance accuracy. This streamlined approach integrates modern heart pulse monitoring with traditional Ayurvedic pulse diagnosis, providing valuable insights into an individual's health and the balance of their doshas (Vata, Pitta, and Kapha).

[0040] While the foregoing written description of the invention enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, combinations, and equivalents of the specific embodiment, method, and examples herein. The invention should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope of the invention as claimed.
