Description

[0001] “AN AUTOMATED PORTABLE WIRELESS DIABETIC FOOT RISK PROFILER DEVICE AND SYSTEM”

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to a foot risk profiler device. More particularly, the present invention relates to an automated portable wireless diabetic foot risk profiler device and system thereof.

[0004] BACKGROUND OF THE INVENTION

[0005] Diabetic foot is a medical condition where individuals with diabetes experience complications in their feet due to prolonged high blood sugar levels. Thereafter, the elevated glucose levels lead to nerve damage and poor blood circulation which increases the risk of serious foot problem like ulcer, infection, gangrene. The end point of this is usually amputation or loss of life in a majority of cases. There is no effective treatment that can reduce the morbidity of diabetic foot infection and thereof prevention of diabetic foot ulcer and infection is always preferred than treating them. Best way of prevention is detection of the risk factors; loss of planter protective sensation and loss of blood circulation at feet to be done earliest and adequate measures are followed accordingly.

[0006] In current time, the doctor detects the nerve damage and poor blood circulation of a diabetic patient’s foot either manually or through a dedicated device. The manual detection involved direct examination by the doctor, where the detection relies on visual and physical examination. Further, the device-based detection utilizes infrared thermography technology, ultrasound and Doppler imaging, pressure and plantar scanning, electrical impedance spectroscopy.

[0007] However, the currently available systems and devices for detection of diabetic foot are not automated, portable or wireless and have significant limitation that affect their usability and effectiveness. Further, the lack of automation makes the device time-consuming and labor-intensive which requires consistent operator input that leads to variability in results and increase the need for specialized training. In addition to this, the doctor usually detects diabetic foot complications using a dedicated device that produces vibration sensations on different areas of the patient’s feet. The patient indicates where the sensation is felt and the doctor manually records the corresponding region. However, because this process relies heavily on manual observation and patient response, there may be a time gap between the patient reports the sensation and when the doctor notes it. This delay, along with subjective nature of the interaction, may introduce significant errors in the assessment, reducing the reliability and accuracy of early diabetic foot detection.

[0008] Additionally, the non-portable devices are generally restricted to clinical settings, which limits access for patient in rural or remote areas, thereby reducing the convenience of regular monitoring. Further, without wireless capabilities, the data cannot be easily transferred or stored remotely, moreover this limitation complicates the real time tracking. The above-mentioned limitation collectively hinders the potential for widespread, efficient and proactive diabetic foot care.

[0009] US20070016079A1 discloses methods and systems of hyperspectral and multispectral imaging of medical tissues. In particular, the invention is directed to new devices, tools and processes for the detection and evaluation of diseases and disorders such as, but not limited to diabetes and peripheral vascular disease, that incorporate hyperspectral or multispectral imaging. However, this invention fails to provide a complete solution to prevent or manage diabetic foot.

[0010] IN202311020165 discloses a preventive diabetic foot care system and method thereof for screening of diabetic foot through a survey and recommended screening modules that empower the physicians to detect the high-risk population easily and effectively. However, this invention does not automated, portable or wireless solution and this invention have significant limitation that affect their usability and effectiveness.

[0011] Therefore, there is a need of an automated portable wireless diabetic foot risk profiler device and system thereof for the objective assessment and continuous monitoring of diabetic peripheral neuropathy expressed as loss of planter protective sensation (FOPS) and peripheral arterial disease (PAD) in patients with Type II diabetes.

[0015] Yet another object of the present invention is to provide an automated portable wireless diabetic foot risk profiler device and system that is cost friendly.

[0016] Still another object of the present invention is to provide an automated portable wireless diabetic foot risk profiler device and system that include an adequate data preservation feature for future clinical implication.

[0030] In another embodiment, the present invention relates to a method to operate automated portable wireless diabetic foot risk profiler system. The method comprises the steps of a) performing neuropathy assessment using a first portable device configured to produce vibration and tactile stimuli and to detect a patient’s response to those stimuli with the help of a remote response button unit acquiring in real time corresponding to the patient’s response; b) performing vascular assessment using a second portable device configured to measure blood pressure and detect pulse wave patterns of the patient; acquiring in real time through a central control panel, c) processing the acquired data in the central control panel to generate a comprehensive foot risk profile, and d) transmitting the processed data and generated foot risk profile to a remote server for storage, synchronization, and remote analysis.

[0031] Referring to Figure 1, a block diagram of the automated portable wireless diabetic foot risk profiler system is depicted. The automated portable wireless diabetic foot risk profiler system (100) comprises at least two portable devices, a central control panel (102), and a remote server (101) that are communicatively connected through a wireless network.

[0032] The first portable device (103) is configured to perform neuropathy assessment by producing controlled vibration and tactile stimuli and detecting a patient’s response to those stimuli acquiring in real time with the help of a remote response button unit, thereby determining sensory nerve functionality.

[0033] The first portable device (103) comprises a load sensor-based monofilament for tactile sensation detection and an electronic tuning fork for vibration sense detection. The load sensor-based monofilament is configured to detect tactile pressure within a range from 0 to 20 grams, providing a resolution of approximately 0.1 gram, thereby quantifying the threshold at which a patient perceives tactile stimuli. The load sensor based monofilament is a plastic and has a diameter in range from 0.2 mm to 0.5 mm / gauge 5.01 to 5.07. The electronic tuning fork is configured to generate vibration within a frequency range of 127 to 129 Hz with an automated amplitude variation from 0 to 50 volts, producing consistent and standardized vibratory stimuli. The first portable device (103) further comprises a display unit, such as a 5 x 5 cm capacitive touchscreen, configured to provide visual control and feedback to the clinician during operation.

[0034] The first portable device (103) is wirelessly connected to a remote response button unit (105), which is an ergonomic handheld wireless controller having a single-button interface and operating within a GHz frequency band. The remote response button unit (105) comprises a tactile feedback mechanism for button press confirmation and is configured to capture a patient’s response to tactile and vibration stimuli produced by the first portable device (103).

[0035] The automated portable wireless diabetic foot risk profiler system (100) detects the response of the patient with a latency of less than 50 milliseconds from button activation, from remote response button, for ensuring high temporal precision and minimizing human error. The remote response button unit (105) further includes TED indicators for connectivity and battery status and supports continuous operation for at least 100 hours of standby time.

[0036] The second portable device (104) comprises an automated Doppler-based blood pressure measurement and pulse wave pattern detection unit and a photoplethysmography (PPG)-based sensor. The Doppler-based unit is configured to measure blood pressure and detect arterial pulse waveforms at a first body part, including the arm, calf, and ankle, using a Doppler probe operating within a frequency range of 7 to 9 MHz.

[0037] The PPG-based sensor is configured to measure blood pressure and pulse wave patterns at a second body part, including the toe, using an optical wavelength of approximately 940 nm and a sampling rate of 100 Hz. The second portable device (104) measures blood pressure within a range of 0 to 300 mmHg with an accuracy of ±3 mmHg and features an automated inflation and deflation mechanism with a safety cutoff at 280 mmHg. The combined Doppler and PPG measurements enable computation of indices such as the ankle-brachial index (ABI) and toe-brachial index (TBI) for peripheral vascular assessment.

[0038] The central control panel (102) comprises an industrial-grade touchscreen display of approximately 15 x 15 cm, an ARM Cortex-based processor, and wireless communication modules for bidirectional data exchange with both the portable devices.

[0039] The central control panel (102) is configured to perform real-time data acquisition, processing, and integration of patient response data from the first portable device

[0040] (103) along with blood pressure and pulse wave data from the second portable device

[0041] (104). The central control panel (102) processes this information to generate a comprehensive foot risk profile, representing neuropathic and vascular health parameters. The automated portable wireless diabetic foot risk profiler system (100) maintains a measurement tolerance of ±2% across all devices to ensure consistency and accuracy. The control panel (102) further features a clinician interface for initiating tests, monitoring progress, and displaying results, including color-coded severity indicators, pulse waveform graphs, and quantitative threshold values.

[0042] The remote server (101) is communicatively linked to the central control panel (102) through an encrypted wireless or cloud-based connection utilizing IEEE 802.15.4 low-power communication protocol operating in the 2.4 GHz ISM band with AES- 128 encryption. The remote server (101) is configured to receive and store the processed data and foot risk profiles generated by the central control panel (102), enabling wireless synchronization, cloud storage, remote access, and longitudinal tracking of patient data. The server supports standard ompliance for interoperability with electronic health record (EHR) systems and ensures compliant data security and privacy standards.

[0043] Additionally, the present invention provides a method (depicted in Figure 2) to operate automated portable wireless diabetic foot risk profiler system. The method comprises stepf of a) performing the neuropathy assessment using the first portable device (103) configured to induce the vibration and tactile sensation and to detect the response of the patient, via the remote response button unit (105) in real time corresponding to response, b) performing the vascular assessment via the second portable device (104) configured to measure blood pressure and detect pulse wave patterns of the patient through the central control panel (102) upon completion of step (a), c) processing the acquired data from step (a) and step (b) in the central control panel (102) to generate a comprehensive foot risk profile and d) transmitting a processed data obtained from step (c) and generated foot risk profile to the remote server (101) for storage, synchronization, and remote analysis.

[0044] EXAMPLE 1

[0045] Preferred implementation of the present invention

[0046] In operation, the present invention performs a structured sequence of assessments. During neuropathy assessment, the clinician applies tactile pressure using the load sensor-based monofilament at predetermined anatomical sites, including the hallux, first, third, and fifth metatarsal heads, mid-sole, and heel, bilaterally. The patient indicates sensation perception by pressing the button on the remote response button unit (105), and the automated portable wireless diabetic foot risk profiler system ( 100) records the corresponding pressure value. For vibration testing, the electronic tuning fork produces vibrations at the medial malleolus and hallux bilaterally, with amplitude ramping from 0 to 50 volts, and the patient’s first perception of vibration is recorded automatically when patient indicates sensation perception by pressing the button on the remote response button unit (105).

[0047] During vascular assessment, the second portable device (104) automatically measures blood pressure and pulse wave patterns at the arm, ankle, and toe. The Doppler probe records blood pressure and arterial flow signals at the brachial, dorsalis pedis and posterior tibial arteries, while the PPG sensor records blood pressure and optical waveforms at the toe. The automated portable wireless diabetic foot risk profiler system (100) automatically calculates ankle brachial and toe brachial indices and displays the results on the control panel (102). All data are transmitted wirelessly to the central control panel (102) with a response time of less than 100 milliseconds for each sensor input.

[0048] The processed data and the generated foot risk profile are subsequently transmitted to the remote server (101) for secure storage, clinical review, and remote monitoring. The automated portable wireless diabetic foot risk profiler system (100) supports cloud-based analytics, trend visualization, and automated report generation in formats such as PDF and CSV, with digital signature support for clinical validation.

[0049] The present invention is configured to operate within a 10-meter wireless range under environmental conditions of 15°C to 35°C and 30% to 75% relative humidity. Safety features include an automatic amplitude limit, motion and artifact detection, timeout control after 60 seconds of continuous activation, and encrypted data transfer for communication integrity.

[0050] The present invention thus provides a quantitative, objective, and standardized diagnostic platform for early detection of diabetic peripheral neuropathy and peripheral arterial disease. By integrating tactile, vibratory, and vascular assessment modalities into a single wireless and portable framework, the present invention enhances diagnostic accuracy, reduces operator dependency, and enables remote data access for continuous patient monitoring and clinical decision support.

[0051] The method begins with initialization and calibration. The clinician powers on the central control panel (102), which automatically establishes wireless communication with the first and second portable devices (103, 104) through a secure 2.4 GHz connection. Each device performs a self-diagnostic and calibration routine lasting approximately thirty seconds to verify sensor accuracy and wireless link integrity. Patient information is entered or retrieved from the database and displayed on the control panel interface.

[0052] Step 1: Neuropathy Assessment The clinician selects the neuropathy assessment mode on the central control panel (102). The first portable device (103), containing the load-sensor-based monofilament and electronic tuning fork, is activated. For tactile testing, the clinician applies the monofilament tip to standardized anatomical sites on the patient’s foot, typically the hallux, first, third, and fifth metatarsal heads, mid-sole, and heel. The first portable device (103) applies controlled pressure within the calibrated 0 - 20-gram range. When the patient perceives the tactile stimulus, the patient presses the button on the handheld remote response button unit (105). The controller transmits the response signal with latency below 50 milliseconds, which is recorded by the first portable device (103) and relayed to the central control panel (102).

[0053] For vibratory testing, the electronic tuning fork automatically generates vibration at 127 - 129 Hz and gradually increases amplitude from 0 to 50 volts. The patient again uses the remote response button unit ( 105) to indicate the first perception of vibration. The automated portable wireless diabetic foot risk profiler system (100) logs the voltage threshold corresponding to the sensory perception point.

[0054] Step 2: Vascular Assessment

[0055] Upon completion of neuropathy testing, the clinician selects the vascular assessment mode. The second portable device (104) performs automated cuff inflation at the arm and ankle triggered by stable pulse detection by doppler probe, and at toe triggered by stable pulse detection by PPG sensor to measure blood pressure in the range of 0 - 300 mm Hg with an accuracy of ± 3 mm Hg. The integrated Doppler probe, operating at 7 - 9 MHz, detects arterial flow at the brachial, dorsalis pedis and posterior tibial arteries, providing audible feedback of pulse detection. Simultaneously, the photoplethysmography sensor placed at the toe measures optical pulse waveforms using a 940 nm light source. The onboard processor captures systolic and diastolic pressures, pulse amplitudes, and wave patterns. These data are transmitted wirelessly to the central control panel (102).

[0056] Step 3: Data Processing and Foot Risk Profiling

[0057] The central control panel (102) receives tactile, vibratory, and vascular data streams in real time with the response time of less than 100 milliseconds. Embedded protocols analyze the patient’s sensory thresholds and vascular indices to determine loss of protective sensation and peripheral arterial status. The central control panel (102) integrates these metrics to generate a combined foot risk profile that categorizes the patient’s neuropathic and vascular condition according to predefined clinical criteria. The display presents numerical results, color-coded risk indicators, and pulse waveform graphs for clinician interpretation.

[0058] Step 4: Data Transmission and Storage

[0059] The processed results and generated foot risk profile are automatically transmitted to the remote server (101) through an encrypted cloud connection using IEEE 802.15.4 protocol with AES-128 encryption. The remote server (101) stores all patient data within a HIPAA-compliant database and synchronizes with electronic health record systems via HL7 FHIR standards. Clinicians can remotely access the reports, trend analyses, and historical comparisons through a secure portal.

[0060] Step 5: Report Generation and Quality Assurance

[0061] The automated portable wireless diabetic foot risk profiler system (100) generates a digital report in PDF and CSV formats containing patient demographics, measured parameters, calculated indices, and risk level classification. Built-in quality assurance software detects motion artifacts, incomplete readings, or out-of-range measurements and prompts the operator for retesting when required. All sensors maintain a measurement tolerance of ± 2 percent across the automated portable wireless diabetic foot risk profiler system (100).

[0062] The technical effect of the present invention lies in providing an automated, portable, and wireless system capable of performing accurate, repeatable, and quantitative assessment of both neuropathic and vascular risk factors associated with diabetic foot complications. Through the integration of a load sensor based monofilament and an electronic tuning fork in the first portable device (103), the automated portable wireless diabetic foot risk profiler system (100) enables objective quantification of tactile and vibratory perception thresholds, eliminating subjectivity inherent in conventional manual monofilament and tuning fork tests. The controlled stimulus generation within defined pressure and frequency ranges ensures uniform testing conditions, resulting in consistent and reproducible neuropathy detection. Through remote response button unit ( 105) reduces the error possibility of manual data capture by two way communication which may cause relay-delay

[0063] Collectively, these features result in significant technical improvements, including enhanced measurement precision, reduced latency, automated analysis, consistent repeatability, and efficient data management.

[0064] Therefore, the present invention provides a reliable, portable, and integrated diagnostic solution that improves the early detection, prevention, and management of diabetic foot complications while reducing human error and clinical workload.

[0065] Many modifications and other embodiments of the invention set forth herein will readily occur to one skilled in the art to which the invention pertain having the benefit of the teachings presented in the foregoing descriptions and the associated drawings. Therefore, it is to be understood that the invention is not to be limited to the specific embodiments disclosed and that modifications and other embodiments are intended to be included within the scope of the appended claims. Although specific terms are employed herein, they are used in a generic and descriptive sense only and not for purposes of limitation.
