Abstract

This invention regarding the medical measurement apparatus includes an apparatus body capable of being held with a thumb and at least one of the subject testing-fingers, that is, the forefinger, the middle finger, the third finger, the fourth finger; a sensor slot bearing within a sensor in which the sensor slot is open at the side of the apparatus body capable of inserting the testing finger; a switch of the sensor in which the switch is controlled by the thumb and disposed at a prescribed position of the apparatus body; and a display device for indicating the result measured by the sensor in which the display device is arranged at the front surface of the apparatus body.

Claims

1. A medical measurement apparatus comprising:

an apparatus body capable of being held with a thumb and at least one of the subject testing-fingers constituted of the forefinger, the middle finger, the third finger and the fourth finger;

a sensor slot bearing within a light receiving element of a optical sensor at a lower portion of the sensor slot in which the sensor slot is open at a side of upper portion of the apparatus body capable of inserting the subject testing finger;

a switch of the sensor in which the switch is controlled by the thumb and disposed at bottom surface of the apparatus body; and

a display device for indicating the measurement result by the sensor in which the display device is arranged at a front surface of the apparatus body.

2. The medical measurement apparatus according to claim 1, wherein the sensor disposed inside the sensor slot is a sensor for measuring the arterial oxygen saturation value.

3. The medical measurement apparatus according to claim 1, in respect of the apparatus body, a portion in which the switch is arranged has a groove extending along the longitudinal direction of the thumb.

4. The medical measurement apparatus according to claim 1, wherein a sensor slot member forming the sensor slot bears a structure capable of attaching to and detaching from the apparatus body.

5. The medical measurement apparatus according to claim 4, wherein a variety of sensor slot members having different inner-diameters could be prepared and selectively attached to the medical measurement apparatus.

6. The medical measurement apparatus according to claim 1, further comprising a sound device for informing a situation in which the reading measured by the sensor exceeds a predetermined numerical limit.
