Description:The present patent application has a reference to an Indian Patent Application No. 201621019145 filed on 03rd June 2016. The present invention is an improvement or modification of the invention claimed in specification for Patent Application No. 201621019145.
Field of Invention
The present invention is related to a wearable device for calibrating and sensing the pulse on a wrist of a subject and more particularly relates to predicting non-communicable disorders.
Background of Invention:
According to Ayurveda, the personalization-based findings are very important for understanding the state of non-communicable disorders. The current wearables and sensors in the prior art or market provide only the HRV-based indications, that do not reflect the personalization-based findings defined in Ayurveda. According to Ayurveda, the pulse location on the wrist changes as per disease, and the sensing mechanisms in the prior art does not have any feedback loop to accurately know the pulse location for best possible signal acquisition.
A person skilled in the art will appreciate that no wearable device in prior art provides accurate Vata, Pitta And Kapha, and Nadi Guna information. The prior art provides accurate results only of the data measured at a particular time but misses out the effect of the circadian rhythm of the day. The device in the prior art maybe configured for sensing the blood pressure, oxygen levels and other factors all day and night along. However, prior art does not teach the devices for measuring the humours of the pulse namely Vata, Pitta and Kapha throughout the day and night. Further, there are very few attempts for predicting the non-communicable disorders through the humours of Vata, Pitta and Kapha.
One such attempt is discussed in the Chinese Patent Application CN107427235B to D. Morris et.al that teaches wrist-wearing type pulse conduction time sensor. The Chinese Patent Application teaches a wrist-worn cardiac monitoring device. The wrist-worn heart monitoring device includes a radial sphygmomanometer configured to output a pressure signal indicative of a pulse pressure wave at a wrist of a user. Further, two or more electrodes are configured to output an electrical signal indicating that a heart of a user has been commanded to contract.
Further, a microphone is configured to output an audio signal indicative of closure of an aortic valve of the user. The wrist-worn heart monitoring device also includes a pulse transit time monitor configured to calculate a pre-ejection period of the heart of the user based at least on the pressure signal, the electrical signal, and the audio signal, and calculate a pulse transit time based at least on the pre-ejection period, the pressure signal, and the electrical signal.
Another U.S Patent Application US9655522B2 to Debiao Li et.al teaches method and system for “push-button” comprehensive cardiac MR examination using continuous self-gated 3D radial imaging. The U.S Patent Application covers the entire heart with high isotropic resolution within a few minutes and requires no physiological gating and minimal user intervention. The U.S Patent Application in no way limits to cardiac cine, myocardial perfusion, coronary MRA, delayed enhancement imaging, myocardial T1-weighted imaging for fibrosis imaging, and myocardial T2-weighted imaging for edema imaging.
Another Korean Patent KR101068116B1 to Im Jae-Jung discloses an apparatus and method for sensing radial arterial pulses for non-invasive and continuous measurement of blood pressure. The sensing device and method measure radial arterial pulse waves to provide non-invasive and continuous brachial blood pressure, central aortic blood pressure, and arterial elasticity. The device includes a sensor unit that can be worn on the radial artery of the wrist to detect accurate pulse waves, an analog processor for separating only necessary signal components from the output of the sensor unit, and a digital signal processor including A / D conversion
Hence, there is a need for a device that calibrates the location of pulse for sensing the radial pulse. Further, there is a need for a device to sense the pulse data on predefined interval of time to capture the effect of the circadian rhythm of the day. Further, there is a need for a device to analyze the stored data and predict the non-communicable disorders based on the stored data.

Now referring to FIGS. 3, 3A and 3B, the operational flow of the device 100 in accordance with the present invention is described. In an initial step 305, the users 105 wears the device 100 on the radial artery. In this step 305, the users initialize the device 100 and connects with the electronic device 120 through the system 115. In a next step 310, the users 105 logs into the electronic device 120 by entering the appropriate credentials. In a next step 315, the alignment module 260 aligns the position of the device 100 on the user’s 105 wrist. In this step 315, the calibration module 225 prompts the user 105 to reposition the device 100 correctly on the wrist if the position is not as per the predefined requirement and control is transferred back to step 315. In this step 315, if the position of the device 100 is correct than the control is transferred towards step 320.
In a next step 320, the device 100 checks for a valid pulse signal through the pulse sensing module 230 if a valid pulse is present than the control is transferred towards step 360 otherwise the device is recalibrated and the control is transferred towards step 325. In this step 325, the device is repositioned on the radial artery. In a next step 330, the calibration module 225 checks for the placement of the device 100 through the optical, force sensors and level adjusters in the sensor module 245. In a next step 335, the device 100 prompts the users 105 by notifying with the LEDs regarding the correct positioning of the device 100.
In a next step 340, the processing module 250 calibrates the position of the device 100 on the z axis that has the sensor assisted level adjuster mechanism that adjust the pressure exerted along z-axis by the pulse sensor onto pulse location. In the next steps 345, 350 and 355, the pressure sensors of the sensor module 245 checks for the pressure exerted by the sensor module 245. In said steps, the sensor module 245 checks for the amount of pressure for detecting the pulse and accordingly, guides the users 105 unless and until the pulse is detected. In case the pulse is not calibrated than control is transferred back towards step 325.Otherwise, after calibrating the position of the device 100 the control is transferred towards step 360 for further processing.
In step 365, the pulse sensing module 230 is configured to periodically read the pulse at predefined interval of time. In step 370, the processing module 250 reads the next interval of time for sensing the pulse and accordingly transfers the control towards step 375 otherwise the control is transferred towards step 365. In step 375, the pulse is captured through pulse sensing module 230. In a next step 380, the captured pulse data is then sent to the electronic device 120 for capturing the pulse data. In a further step 385, the captured pulse data is stored in the database 215. In a next step 390, the quota of readings is checked and accordingly, the oldest reading is deleted. In last step 395, the data is sent to the system 115 for further processing.

Example 1:
In Example 1, implementation of detecting a non-communicable disease through device 100 is disclosed. Variations, modifications, and enhancements to the described examples and implementations and other implementations may be made based on what is disclosed. In this example 1, the continuous pulse signal data is recorded and saved. On a continuous basis, while the data is being saved, every one-minute pulse data is used to compute different vital parameters or features such as heights, angles, peak to peak differences, areas under the curve, and their statistical values.
From the vital parameters and from the Ayurvedic parameters of Vata, Pitta and Kapha, the health parameters are computed such as for calculating body hydration, five vital parameters are considered out of that high Vata and low area under the curve are considered. Similarly, for toxin accumulation, four vital parameters are considered out of which high area under the curve and heights are considered. For calculating gut health, the toxin information is used and six vital parameters are considered for example Angles 1, Angles 2 may be considered. For calculating stress levels, four vital parameters may be considered for example two high statistical standard deviation of area under the curve, high statistical standard deviation of heights or the like. The above-mentioned computations are performed every minute.
The indicators mentioned in example 1 such as angles, curves, area under the curve depict the overall physical and mental wellbeing of the person at that moment and are stored in the database. In order to indicate or predict non-communicable disorders also identified as phenomenon, these indicators over period of time are analyzed to find out trends leading towards any of non-communicable disorders such as, but not limited to diabetes, hypertension, hormonal imbalance or the like. For example, if the vital parameter Kis observed along with body hydration, toxin accumulation and stress levels, then this condition is one of the prominent conditions of diabetes. There are such multiple combinations of vital and health parameters whose trends lead towards the prediction of non-communicable disorders.
The foregoing description of specific embodiments of the present invention has been presented for purposes of illustration and description. They are not intended to be exhaustive or to limit the present invention to the precise forms disclosed, and obviously many modifications and variations are possible in light of the above teaching.
