Abstract

The invention discloses a finger type pulse and blood oxygen measuring device, including an upper shell suite and a lower shell suite that are installed with silica gel soft finger pad, and a semi-closed holding. A removable power supply module is installed in the lower shell suite. The beneficial effect of the invention is that because of the adoption of the removable type power supply module which is able to load the battery, it is easier to assemble and disassemble the battery. Additionally, the structure of the device facilitates manufacturing, enhances quality, and also increases the comfort of a person using the device.

Claims

1. A finger type pulse and blood oxygen measuring device, comprises:

an upper shell suite and a lower shell suite that are installed with silica gel soft finger pads, and a semi-closed holding cavity shaped by the coordination of the silica gel soft finger pads that are installed within the upper shell suite and the lower shell suite;

wherein the silica gel soft finger pads installed within the upper shell suite and the lower shell suite have optical windows which are opposingly aligned with respect to each other, the silica gel soft finger pads each include a transparent section of silica gel which forms the optical window resulting in the optical window and the remaining portion of the associated silica gel soft finger pad being a single silica gel member free of joints therebetween,

the optical window not being formed by a hole through the associated silica gel soft finger pad, the optical window extending completely through the associated silica gel soft finger pad, a light emitting diode is fixed on the transparent silica gel optical window of one of the silica gel finger pads, the light emitting diode being located on the side of the one silica gel finger pad on a side opposite from where the finger would make contact;

a power supply module is removably installed in the lower shell suit, wherein the power supply module is configured to hold batteries in two elongated compartments that are separate and parallel and each have two open sides when the power supply module is disconnected from the lower shell suite, a first open side of each of the two open sides of the two elongated compartments is configured to expose a lateral side of the batteries and a second open side of each of the two open sides of the two elongated compartment is configured to provide access to a terminal end of batteries when the batteries are positioned in the associated one of the two elongated compartments;

a battery installation groove lid is located on each of the two elongated compartments along the first open side to prevent batteries from falling from the power supply module while the power supply module is disconnected from the lower shell suite,

a wall between the elongated compartments has a T-shaped cross section which forms a flanging boss structure proximate the first open side and extending over a portion of the first open side of the two elongated compartments to cooperate with the respective battery installation groove lid to retain batteries in the elongated compartments when the power supply module is disconnected from the lower shell suite, wherein the battery installation groove lid located on each elongated compartment is fixed in position between the power supply module and the bottom of the lower shell cover by clamping therebetween when the battery supply module is engaged with the lower shell suite;

wherein one sidewall of each of the elongated compartments includes a circular arc structure stretching from the surface of a bottom of the power supply module along the second open side;

a fixed clip is detachably positioned on an end of the wall between the elongated compartments to prevent batteries from sliding from the power supply module through the second open side when the power supply module is detached from the lower shell suite, wherein the power supply module is configured to allow greater ease in battery changing by removal of the fixed clip and sliding out of old batteries and sliding in of new batteries without the need to pry batteries out of the power supply module.

2. The finger type pulse and blood oxygen measuring device as set forth in claim 1 characterized in that the upper shell suite includes an upper shell cover, a lens cover and a push-button device which is installed in a channel of a concave corresponding to the top end of the upper shell cover;

a control circuit board is fixed in an inner side of the bottom of the upper shell cover by mainboard fastener.

3. The finger type pulse and blood oxygen measuring device as set forth in claim 2 characterized in that the bottom of the control circuit board is installed with optoelectronic sensors, and the top end of the circuit board installs with display screen.

4. The finger type pulse and blood oxygen measuring device as set forth in claim 1 characterized in that the lower shell suite mainly includes silica gel soft finger pad, light emitting diode (LED) and lower shell cover;

the light emitting diode (LED) connects with the control circuit board, and the silica gel soft finger pad is installed in a channel of a concave of the top end of the lower shell cover.
