Smart Wearable Device for Health Watch
First Claim
1. A wearable device comprising:
- a central unit substantially similar to a wrist watch dial;
a flexible wristband attached to the central unit wherein the central unit and the flexible wristband together forming the wearable device;
a first, a second and a third sensor pads mounted on the flexible wristband wherein the first and the second sensor pads are mounted on the inner side of the flexible wristband touching the skin to collect first and second electrical signals from the respective locations when the wearable device is tied around the wrist and the third sensor pad is mounted on outer surface of the flexible wrist band to collect a third electrical signal when a finger is placed over the third sensor pad;
an ejectable tray housed within the central unit;
a set of micro needle and enzyme test strip pairs housed in the ejectable tray;
a fourth sensor pad mounted on the outer surface of the flexible wrist band conveniently closer to the third sensor pad wherein the fourth sensor pad operative as Photoplethysmogram (PPG) sensor providing a fourth electrical signal;
a spring and latch mechanism deployed within the central unit comprising a first spring and a latch to hold the ejectable tray within the central unit and a second spring, when activated, releases the latch causing the ejectable tray to protrude outside of the central unit for accessing at least one micro needle and enzyme test strip pair;
a processor mounted within the central unit to process the first, the second, the third and the fourth electrical signal respectively received from the first, second, third, fourth sensor pads and a fifth electrical signal from the micro needle and enzyme test strip pair, where in the first, second, third, fourth sensor pads and the micro needle and enzyme test strip pair are electrically coupled to the processor; and
a display device integrated within the central unit to display a plurality of health parameters determined from the first, the second, the third, the fourth and the fifth electrical signals.

Abstract
A wearable device comprising a display dial configured to display various health parameters, a wristband assisting the device to wear on wrist, an eject-able tray comprising a micro-chip, a first spring coupled to the eject-able tray, at least one latch provided with a second spring to hold the eject-able tray within the device by compressing the first spring, and a health monitoring unit provided with multiple sensors to determine various health parameters, wherein compression of the second spring results in the latch to release the eject-able tray which in turn relaxes the compressed first spring to eject the micro-chip outside the device for collecting blood samples. The microchip comprises at least one micro-needle and an enzyme test strip for collecting and analyzing the blood samples. The health monitoring unit comprises at least three conductive sense pads which are collectively operable to provide electrocardiograph (ECG) information.
