Finger clip type oximeter

Abstract

The invention provides a finger clip type oximeter. The finger clip type oximeter comprises a signal acqusition unit, a signal processing unit, a display unit and a shell, wherein the signal acqusition unit is used for acquiring a human body blood oxygen signal and a human body pulse rate signal; the signal processing unit is used for calculating a human body blood oxygen parameter based on the blood oxygen signal and calculating a human body pulse rate parameter based on the pulse rate signal; the display unit is used for displaying the blood oxygen parameter and the pulse rate parameter; an upper shell and / or a lower shell of the shell is provided with an auxiliary component; the auxiliary component is provided with a recess which is conformal to a human body finger pad and a positioning component; the positioning component can be used for determining whether the position of the human body finger pad relative to the recess is correct. According to the finger clip type oximeter, the problem that finger clipping is not accurate can be solved, and a user can also be stimulated and awakened when the human body blood oxygen parameter is over-low or the pulse rate parameter is over-low.

Description

technical field [0001] The invention relates to a finger-clip oximeter, which is used for blood oxygen detection and pulse rate detection of a human body, and belongs to the technical field of medical equipment production. Background technique [0002] At present, finger-clip blood oxygen parameter detection has been widely used clinically. The blood oxygen parameters of peripheral tissues are calculated by detecting the absorbance of red light or infrared light of different wavelengths on the congested peripheral tissues of the human body, such as fingers and earlobes. . In the prior art, a finger clip oximeter generally includes an upper finger clip housing on the upper surface of the finger hole and a lower finger clip housing on the lower surface of the finger hole. The upper housing and the lower housing are wound around a common pivot by a torsion spring. The shafts rotate and close together to form a finger hole, which clamps the finger to be measured to measure bloo...

AI Technical Summary

Problems solved by technology

However, due to the difference in the thickness, length, and external shape of the user's fingers, the oximeter's pinching of the measuring finger is inaccurate or too tight, which affects blood circulation or inaccurate measurement positions, and ultimately leads to inaccurate measurement parameters.

[0003] In addition, some people often suffer from shortness of breath during sleep, and shortness of breath will lead to low blood oxygen saturation and pulse rate parameters, which will threaten human life. It is very necessary to wake up the structure of the human body when it is low, and it can avoid the danger of life caused by the low oxygen saturation of the human body

[0004] In order to solve the above-mentioned technical defects of the existing finger-clip oximeters, medical device developers urgently need to develop a device that can not only solve the technical problem of inaccurate finger pinch pressure, but also can be used when the blood oxygen parameters of the human body are too low or the pulse rate parameters are too low. When the temperature is too low, the finger clip oximeter will remind the human body to wake up
