Smart wearable device for health watch
First Claim
1. A wearable device (201) comprising:
- a central unit (202) similar to a wrist watch;
a flexible wristband (204) attached to the central unit (202) wherein the central unit and the flexible wristband together forming the wearable device for wearing on a wrist;
a first, a second and a third sensor pads (208A, 208B and 208C) mounted on the flexible wristband (204) wherein the first and the second sensor pads (208A and 208B) are mounted on the inner side of the flexible wristband (204) configured to touch a skin part on the wrist to collect a first and a second electrical signals from the respective locations when the wearable device (201) is tied around the wrist and the third sensor pad (208C) is mounted on outer surface of the flexible wrist-band (204) and configured to collect a third electrical signal when a finger is placed over the third sensor pad (208C);
an ejectable tray (1802) housed within the central unit (202);
a set of micro needle (170A) and enzyme test strip pairs (170B) housed in the ejectable tray (1802);
a fourth sensor pad (210) mounted on the outer surface of the flexible wrist-band (204) closer than the first and second sensor pads to the third sensor pad (208C) wherein the fourth sensor pad (210) operative as Photoplethysmogram (PPG) sensor providing a fourth electrical signal;
a spring and latch mechanism (1801 through 1806) deployed within the central unit (202) comprising a first spring (1805 or 1806) and a latch (1803 or 1804) to hold the ejectable tray (1802) within the central unit (202) and a second spring (1801), when activated, releases the latch (1803 and 1804) causing the ejectable tray (1802) to protrude outside of the central unit (202) for accessing at least one micro needle (170A) and enzyme test strip pair (170B);
a processor (314) mounted within the central unit (202) to process the first, the second, the third and the fourth electrical signals respectively received from the first, second, third, fourth sensor pads (208A, 208B, 208C and 210) and a fifth electrical signal from the enzyme test strip (170B), where-in the first, second, third, fourth sensor pads (208A, 208B, 208C and 210) and the enzyme test strip (170B) electrically coupled to the processor (314); and
a display device (320) integrated within the central unit (202) 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.
