Description:FIELD OF THE INVENTION

[0001] The present invention relates to a handheld physiological metrics monitoring assistive pen that enables real-time measurement of multiple health parameters, ensuring accurate and continuous tracking of physiological parameters, immediate access to medical information, and supporting timely awareness, personal health management, and clinical decision-making through reliable data collection and instant result display.

BACKGROUND OF THE INVENTION

[0002] Monitoring physiological parameters such as blood glucose, oxygen saturation, and body temperature is essential for individuals managing chronic conditions and for maintaining general health awareness. Conventional devices often require multiple bulky instruments, invasive sampling methods, or frequent clinic visits, which are inconvenient for daily use and limit timely monitoring. Users face challenges including discomfort from invasive sampling, difficulty carrying and operating separate devices, lack of real-time data access, and limited integration with medical reporting systems. These issues leads to missed health variations, delayed interventions, and reduced user compliance. Therefore, there is a strong need for a compact device that enables convenient, accurate, and continuous physiological monitoring in real time.

[0003] Several portable health monitoring devices are currently available, including glucometers, pulse oximeters, non-contact thermometers, and wearable fitness trackers. While these devices serve specific purposes, they each come with drawbacks. Glucometers require invasive finger pricking and separate test strips, causing discomfort and hygiene concerns. Pulse oximeters and thermometers function as standalone units, requiring users to carry multiple devices for comprehensive monitoring. Wearable trackers provide only approximate readings, often lacking medical-grade accuracy and reliability. Moreover, most existing devices do not integrate multiple parameters into one compact unit, nor do they support seamless data sharing with medical systems. This creates inconvenience, inconsistent usage, and limits timely health management for patients and caregivers.

[0004] US20120323097A9 discloses a patch for sampling one or more analytes through the skin of a patient comprises an electrode layer for positioning adjacent to the skin of a patient; and means for actuating the electrode layer to induce the withdrawal of analytes through the skin by reverse iontophoresis. A first reservoir in the patch contains an electrically conducting medium such as a liquid electrolyte, which can be controllably delivered onto a surface of the electrode layer adjacent to the skin to increase the conductivity between the electrode layer and the skin. Means are provided for transporting the analytes to a location where they are to be analysed. The patch may comprise a second reservoir containing a drug for transdermal delivery to the patient. An actuator may stretch and/or compress the reservoirs to expel their contents. The actuator may comprise a generally planar mesh formed from a shape memory alloy.

[0005] US8190223B2 include a handheld multi-parameter patient monitor capable of determining multiple physiological parameters from the output of a light sensitive detector capable of detecting light attenuated by body tissue. For example, in an embodiment, the monitor is capable of advantageously and accurately displaying one or more of pulse rate, plethysmograph data, perfusion quality, signal confidence, and values of blood constituents in body tissue, including for example, arterial carbon monoxide saturation (“HbCO”), methemoglobin saturation (“HbMet”), total hemoglobin (“Hbt”), arterial oxygen saturation (“SpO2”), fractional arterial oxygen saturation (“SpaO2”), or the like. In an embodiment, the monitor advantageously includes a plurality of display modes enabling more parameter data to be displayed than the available physical display real estate.

[0006] Conventionally, many devices are available in the market for monitoring physiological parameters. However, the cited inventions lack to provide a compact, user-friendly, and multi-functional solution. Existing technologies either focus on a single physiological parameter, demand invasive sampling, or present bulky designs, which hinder portability, continuous monitoring, and seamless integration with clinical reporting systems, limiting widespread daily usability.

[0007] In order to overcome the aforementioned drawbacks, there exists a need in the art to develop a pen that is capable of integrating glucose, oxygen saturation, and temperature monitoring within a single handheld unit. Such a device must provide real-time, accurate, and secure health insights while supporting clinical reporting, thereby ensuring convenience, compliance, and timely medical interventions.

DETAILED DESCRIPTION OF THE INVENTION

[0018] The following description includes the preferred best mode of one embodiment of the present invention. It will be clear from this description of the invention that the invention is not limited to these illustrated embodiments but that the invention also includes a variety of modifications and embodiments thereto. Therefore, the present description should be seen as illustrative and not limiting.

[0019] In any embodiment described herein, the open-ended terms "comprising," "comprises,” and the like (which are synonymous with "including," "having” and "characterized by") may be replaced by the respective partially closed phrases "consisting essentially of," consists essentially of," and the like or the respective closed phrases "consisting of," "consists of, the like.

[0020] As used herein, the singular forms “a,” “an,” and “the” designate both the singular and the plural, unless expressly stated to designate the singular only.

[0021] The present invention relates to a handheld physiological metrics monitoring assistive pen that provides real-time monitoring of multiple physiological parameters, enabling accurate health tracking and immediate access to essential medical information, while also allowing integration of collected physiological data into existing medical reporting system to ensure clinical usability, support secure healthcare communication, and enhance the effectiveness of medical decision-making.

[0022] Referring to Figure 1, an isometric view of a handheld physiological metrics monitoring assistive pen is illustrated, comprising a contoured pen-shaped housing 101, a microneedle unit arranged on the housing 101, includes a needle housing 102 with an ergonomically optimized finger groove 103, a spring-loaded platform 104, a knob 105 installed on the exterior surface of the housing 101, a microfluidic conduit, comprises of a micro-duct 106 positioned adjacently to the microneedle channel 107, a glucose test strip 108, a reverse iontophoresis module comprises a microfluidic chamber 109, a blood oxygen saturation monitoring module installed on the housing 101 comprising a detachable clip 110 with an LED (Light Emitting Diode) emitter 111, a non-contact body temperature monitoring unit 112 integrated within the housing 101, an embedded compact OLED display 113 mounted on an exterior portion of the housing 101 and a glucose quantification processing module 114 arranged within the needle housing 102.

[0023] The pen disclosed in the present invention includes a contoured pen-shaped housing 101 for writing purposes but also for monitoring critical physiological parameters of a patient. The housing 101 is ergonomically designed for ease of handling and multifunctional operation, providing a portable solution for routine health monitoring integrated within a writing instrument.

[0024] A dual-mode blood glucose monitoring module is positioned within the housing 101, capable of performing both invasive and non-invasive glucose measurements. In the invasive method, the pen employs a microneedle unit designed for minimally invasive blood sample extraction.

[0025] In a preferred embodiment of the present invention, a contact sensor is embedded within the housing 101 to detect the contact of the user with the user. The contact sensor is constructed using capacitive touch elements embedded within the housing 101. The outer casing incorporates a thin insulating layer above the conductive surface to ensure safe usage. When the user holds or touches the pen, the sensor detects changes in electrical resistance or capacitance caused by skin contact. This change is transmitted to an inbuilt microcontroller for processing, confirming the user’s grip or touch.

[0026] The input means of the device includes a user interface installed in a computing unit wirelessly linked to the microcontroller of the pen. This interface receives input commands from the user regarding initiation of sample collection and glucose analysis. The user interacts with the interface through a touch display, keyboard, or other input methods available on the computing unit. The computing unit mentioned herein includes, but not limited to smartphone, laptop, tablet. The wireless communication between the microcontroller of the device and the computing unit is achieved through a communication module.

[0027] The communication module mentioned herein includes, but not limited to Wi-Fi (Wireless Fidelity) module, Bluetooth module, GSM (Global System for Mobile Communication) module. The communication module used in the device is preferably the Wi-Fi module. The Wi-Fi module enables wireless communication by transmitting and receiving data over radio frequencies using IEEE 802.11 protocols. It connects to a network via an access point, converting digital data into radio signals. The module processes TCP/IP protocols for data exchange, interfaces with microcontrollers through UART/SPI, and ensures encrypted communication using WPA/WPA2 security standards for secure and efficient wireless connectivity.

[0028] The microneedle unit is designed with a specialized needle housing 102 that features an ergonomically optimized finger groove 103. This groove 103 guides and aligns the user’s fingertip accurately, ensuring correct placement for blood sampling, improving precision, minimizing discomfort, and reducing chances of incorrect deployment during glucose monitoring procedures.

[0029] A spring-loaded platform 104 is arranged within the needle housing 102, which is manually triggered through a knob 105 on the housing 101 that facilitates controlled microneedle deployment. When the user manually rotates the knob 105 in the clockwise direction, the knob 105 releases the compressed spring force. This controlled release drives the microneedle forward to puncture the skin minimally and extract a small blood sample. The spring loaded platform 104 ensures consistent penetration depth, reducing pain and preventing accidental over-insertion. Once the sample is collected, the spring automatically retracts the needle back into the needle housing 102, maintaining hygiene and preventing exposure.

[0030] The knob 105 is further linked to a needle replacement arrangement, which disengages a needle lock when the user rotates the knob in opposite direction, allowing safe removal and replacement of needles without direct contact.

[0031] The knob 105 is connected to an internal cam that controls the needle lock securing the microneedle in place. During normal operation, the lock holds the needle firmly, preventing accidental displacement. When the user rotates the knob 105, the cam action mechanically disengages the lock, releasing the needle from its holder. This enables the spent needle to be safely ejected or withdrawn without the user touching the needle directly.

[0032] Once the microneedle extracts the blood sample, it is directed into a microfluidic conduit containing a finely structured micro-duct 106 adjacent to the microneedle channel 107. The transport of blood relies on capillary action, a phenomenon where liquid moves through narrow spaces without external force. This occurs because of the adhesive force between blood and the duct’s inner walls combined with cohesive forces within the liquid, allowing the blood to be naturally pulled forward. The micro-duct 106 ensures smooth, precise, and contamination-free flow of the sample in controlled volume. The blood then reaches the glucose test strip 108, where electrochemical sensors perform glucose analysis.

[0033] To enhance operational efficiency, the invasive method further integrates a humidity detection and strip activation module, wherein a humidity sensor placed proximate to the test strip 108 detects the presence of blood and initiates glucose quantification. The humidity sensor measures humidity by using a hygroscopic conductive material, often a polymer, whose electrical resistance changes with moisture absorption. As humidity levels increase, the conductive material absorbs moisture, causing its resistance to decrease. The sensor measures these changes in resistance and converts them into an electrical signal that represents the relative humidity. The final signal is then sent to an inbuilt microcontroller of the pen.

[0034] A strip 108 rotation assembly is incorporated, executing a 90-degree rotation of the blood-laden test strip 108 into a glucose quantification module, where electrochemical analysis takes place. The strip 108 rotation assembly consists of a miniature rotating platform 104 or holder connected to a micro-motor or spring-driven gear arrangement. Once the blood sample is deposited, the strip 108 rotation assembly is actuated and executes a controlled 90-degree rotation of the strip 108, shifting it from the sampling position to the analysis position. This movement aligns the test strip 108 with the electrochemical sensing electrodes inside the quantification module.

[0035] Electrochemical processing is a technique that measures chemical reactions using electrical signals to determine the concentration of specific analytes, such as glucose in blood. In this method, a test strips 108 coated with enzymes, like glucose dehydrogenase, reacts with the target molecule, producing an electroactive byproduct. Electrodes on the strip 108 detect this reaction by measuring the generated electrical current or potential difference. The magnitude of the electrical response is directly proportional to the analyte concentration. This data is then processed by the microcontroller to provide accurate readings.

[0036] In addition, a strip 108 replacement unit ensures seamless relocation and replacement of the glucose test strip 108, thereby improving hygiene and usability. The strip 108 replacement unit consists of a rotatable cartridge chamber aligned with the microfluidic conduit and rotation assembly. After a strip 108 is used and analyzed, an ejection assembly, such as a spring-loaded pusher displaces the spent strip 108 into a disposal slot. Simultaneously, the cartridge advances the next unused strip 108 into the sampling position.

[0037] The non-invasive glucose monitoring method employs a reverse iontophoresis module integrated within the housing 101. The reverse iontophoresis module is equipped with silver chloride electrodes, which induce transdermal glucose extraction by driving sweat through the skin. A dedicated microfluidic chamber 109 is arranged to collect sweat induced by reverse iontophoresis, while an electrochemical biosensor placed above the chamber facilitates real-time measurement of glucose concentration.

[0038] When activated, the silver chloride electrodes generate a mild electric field across the sweat collected in the microfluidic chamber 109, causing ion migration and inducing sweat extraction that carries glucose molecules transdermally. The electrochemical biosensor is mounted above the chamber, where glucose molecules react with enzyme-coated electrodes. The resulting electrochemical signal is processed in real-time to provide precise glucose concentration readings.

[0039] A blood oxygen saturation (SpO₂) module is housed within the pen. The blood oxygen saturation monitoring module includes a detachable fingertip clip 110 fitted with an LED emitter 111 and a photodetector. The oxygen saturation monitoring module operates on the principle of differential light absorption by oxygenated and deoxygenated hemoglobin, providing precise SpO₂ readings. The fingertip clip 110 is attached to the pen through an electromagnet.

[0040] The electromagnet is made of insulated copper wire wound into a coil and a ferromagnetic material is placed inside the coil to enhance the magnetic field. When an electric current flows through the coil of wire, it creates a magnetic field around the wire. The magnetic field is concentrated and intensified by the core material inside the coil and strengthens the overall magnetic field produced by the coil. The created magnetic field attracts the clip 110 creating a connection. When the current is turned off, the magnetic field collapses, and the electromagnet no longer attracts the clip 110 and clip 110 is released.

[0041] The fingertip clip 110 measures blood oxygen using the principle of pulse oximetry. The fingertip clip 110 contains the LED emitter 111 that emits light, typically red and infrared, through the fingertip, and a photodetector on the opposite side receives the transmitted light. Oxygenated hemoglobin and deoxygenated hemoglobin absorb light differently at these wavelengths. By comparing the intensity of absorbed light at both wavelengths during each pulse, the oxygen saturation monitoring module calculates the ratio of oxygenated to total hemoglobin in the blood. This ratio provides the oxygen saturation level (SpO₂).

[0042] A non-contact body temperature monitoring unit 112 is integrated within the housing 101. This module enables precise body temperature measurement without physical contact, thereby ensuring hygiene and comfort during frequent use. The temperature monitoring unit 112 consists of a temperature sensor that detects the temperature of the user’s body.

[0043] The temperature sensor operates by using a temperature-sensitive element, such as Resistance Temperature Detector (RTD), which changes its electrical resistance with temperature variations. As the temperature rises or falls, the resistance of the element changes accordingly. This change in resistance is converted into an electrical signal by the sensor's circuitry, which then processes the signal to determine the temperature.

[0044] The microcontroller is embedded in the pen, which serves as the central processing unit for all physiological monitoring modules. The microcontroller is operatively linked to a glucose quantification processing module 114, designed to interpret electrical currents generated by the electrochemical interaction between blood glucose and glucose dehydrogenase enzyme on the test strip 108. These electrical signals are converted into calibrated glucose concentration readings displayed on an OLED display 113 mounted on the housing 101.

[0045] The glucose quantification processing module 114 is constructed with an electrochemical sensing circuit and signal conditioning unit. When the blood or sweat sample contacts the enzyme-coated test strips 108, glucose reacts with glucose dehydrogenase, producing electrons. Electrodes on the strip 108 capture this reaction as an electrical current. The signal is transmitted to the module’s sensing circuit, where it is amplified and filtered to remove noise. The microcontroller interprets the processed signal, converting current intensity into a glucose concentration value. The quantified reading is then displayed on the OLED display 113 and optionally transmitted wirelessly for medical use.

[0046] The OLED (Organic Light Emitting Diode) display 113 works by using organic compounds that emit light when an electric current passes through them. The OLED display 113 consists of multiple thin layers: a substrate, anode, organic emissive layer, and cathode. When voltage is applied, electrons from the cathode and holes from the anode recombine in the emissive layer, releasing energy as visible light. Each pixel is made of sub-pixels (red, green, and blue), which combine to produce full-color images.

[0047] In addition, the microcontroller comprises a multi-sensor data integration module, which aggregates data from the glucose monitoring unit, SpO₂ module, and body temperature sensor. The integrated results are processed to provide synchronized physiological metrics that are simultaneously displayed on the OLED display 113 and transmitted to an external user interface.

[0048] The interface incorporates a data export module operatively connected to the microcontroller, which formats physiological data into standardized medical reporting formats. The module enables secure and encrypted transmission of data to healthcare providers or electronic health record unit, ensuring clinical usability and patient data security.

[0049] The data export module includes a data formatting unit, encryption engine, memory buffer, and wireless communication module such as Bluetooth, Wi-Fi, or NFC. Physiological data from glucose, SpO₂, and temperature sensors are first processed by the microcontroller and sent to the formatting unit, which converts the values into standardized medical formats like HL7 or FHIR. The encryption engine secures the data using AES or RSA. The wireless unit then transmits the encrypted reports to healthcare providers or electronic health record unit, ensuring accuracy, usability, and privacy.

[0050] In an exemplary embodiment of the present invention, smart health-monitoring pen is used by diabetic patients who also need to track other vital signs. For instance, consider a working professional with diabetes who carries this pen daily. During a meeting or while traveling, working professional discreetly use the microneedle unit for quick invasive glucose measurement or switch to the non-invasive reverse iontophoresis module for painless monitoring. The same pen also allows the working professional to clip 110 their fingertip to measure blood oxygen saturation (SpO₂) and check body temperature instantly. The results appear on the OLED display 113 and are securely transmitted to their doctor’s electronic health record unit for continuous remote monitoring, ensuring convenience, hygiene, and real-time medical support.

[0051] The present invention works best in the following manner, where the contoured pen-shaped housing 101 that supports both writing and physiological monitoring. The dual-mode blood glucose monitoring module operates either invasively or non-invasively, wherein the invasive method utilizes the microneedle unit comprising the needle housing 102 with an ergonomically optimized finger groove 103, the spring-loaded platform 104 actuated by the knob 105 for controlled microneedle deployment, and the needle replacement arrangement linked to the knob 105 for safe removal and replacement. The extracted blood flows through the microfluidic conduit with the micro-duct 106, which guides the sample via capillary action to the glucose test strip 108. A humidity detection and strip 108 activation module detects blood presence and initiates analysis, while the glucose strips 108 rotation assembly executes the 90-degree rotation of the blood-laden strip 108 into the glucose quantification module, and the replacement unit manages cartridge relocation for new strips 108. In the non-invasive mode, the reverse iontophoresis module with silver/silver chloride electrodes induces transdermal glucose extraction, directing sweat into the microfluidic chamber 109, where an electrochemical biosensor measures glucose in real time.

[0052] In continuation, the pen also integrates the blood oxygen saturation monitoring module with detachable clips 110 housing the LED emitter 111 and photodetector to measure SpO₂ through differential light absorption, and the non-contact body temperature monitoring unit 112 for accurate temperature assessment. The microcontroller processes sensor outputs via the glucose quantification processing module 114, interpreting electrochemical currents and converting them into glucose readings, and the multi-sensor data integration module, which aggregates glucose, SpO₂, and temperature data for synchronized display on the OLED display 113. The user interface, wirelessly connected to the microcontroller, enables input commands and incorporates the data export module that formats physiological data into standardized medical reports and transmits them securely to healthcare providers or personal health records through encrypted protocols.
