Abstract

Disclosed is a fingerstall oximeter including a soft gum coat and a case, a display screen for displaying measurement results is provided on the upper part of the case and an open corresponding to the display screen is provided on the soft gum coat. The soft gum coat is slipped over the outside of the case, the case is used to accommodate and protect a circuit board, and a chamber for accommodating finger is formed and rounded by the upper part of the case and the bottom of the soft gum coat, for accommodating a finger to be measured. A first measurement module is provided on the bottom of the soft gum coat and a second measurement module is provided within the case at a position corresponding to the first measurement module.

Claims

1. A fingerstall oximeter comprising:

a soft gum coat,

a case, which includes a circuit board chamber and a battery chamber, the circuit board chamber and the battery chamber being juxtaposed and separated by a partition,

a display screen provided on an upper part of the case to display a measurement result, wherein an opening is provided on the soft gum coat at a position corresponding to the display screen, the soft gum coat slipped over the outside of the case, wherein the circuit board chamber of the case accommodates and protects the circuit boards and the battery chamber of the case accommodates a dry cell, and a chamber for accommodating finger is formed and surrounded by a lower part of the case and the bottom of the soft gum coat to accommodate a finger to be measured,

a first measurement module provided on the bottom of the soft gum coat,

a second measurement module provided in the case at a position corresponding to the first measurement module, and

a finger stop plate is provided in the lower part of the case, wherein the chamber for accommodating finger is surrounded by the finger stop plate and the bottom of the soft gum coat.

2. The fingerstall oximeter of claim 1, wherein only one dry cell can be accommodated in the battery chamber for supplying power to the fingerstall oximeter.

3. The fingerstall oximeter of claim 1, wherein the finger stop plate is shaped to be an arc, and the front side of the case is formed to be an arc-shaped edge corresponding to the arc.

4. The fingerstall oximeter of claim 1, further comprising a soft gum pad provided on the finger stop plate.

5. The fingerstall oximeter of claim 1, wherein the finger stop plate is combined with the case by means of a buckle or a screw, or the finger stop plate and the case are formed integrally.

6. The fingerstall oximeter of claim 1, further comprising a flange provided on the upper part of the end of the case, a roundabout part adapting the flange provided on the soft gum coat, wherein the roundabout part and the soft gum coat form a trench into which the flange can be embedded, so that the case and the soft gum coat can be assembled closely.

7. The fingerstall oximeter of claim 1, wherein a battery cover is provided on the back side of the case, and the battery cover is connected to the case via a pivot and can be buckled up with the case in a sliding manner.

8. The fingerstall oximeter of any one of claims 1, 2 and 3 to 7, wherein the case is made from metal materials or hard organic materials.
