Description

Blood oxygen meter capable of measuring body temperature

TECHNICAL FIELD The present invention relates to the field of medical device technology, and in particular to an oximeter capable of measuring body temperature. Techniques Blood oxygen and body temperature are two indicators that reflect and measure the physiological function of human body. In clinical practice, the two have a certain correlation. Therefore, in the diagnosis and evaluation of multiple diseases and physiological conditions, blood oxygen and body temperature are often needed. Combined for comprehensive assessment to improve the accuracy of diagnosis and treatment.

At present, when users are testing body temperature and oxygen saturation, and comprehensively evaluating the two, it is often necessary to use two instruments, a thermometer and an oximeter, which is not only not conducive to comprehensive analysis and recording of test results, but also If the user needs to perform the test when going out, the two instruments must be carried at the same time, which brings inconvenience to the user.

To this end, a blood oxygen meter that measures blood oxygen and body temperature by a single instrument has been designed, as shown in Figure 1, which is a finger-clip blood disclosed in the Chinese utility model patent with the authorization number CN 201426987U. An oxygen meter comprising a pluggable housing 1 and a body temperature sensor 2. Wherein, a circuit board and a blood oxygen signal collection module are disposed in the housing 1 (the internal structure of the housing 1 is not shown in the figure), and a blood oxygen signal processing module and a body temperature signal processing module are integrated on the circuit board. . The blood oxygen signal collection module is configured to collect the blood oxygen signal of the detected object and send it to the blood oxygen signal processing module; the blood oxygen signal processing module is configured to convert the blood oxygen signal into blood such as blood oxygen saturation. Oxygen information, and send it out.

Send to the body temperature signal processing module. When the above-mentioned finger-clip oximeter is used, the blood oxygen signal of the subject can be collected by means of the blood oxygen signal collection module, or the body temperature can be transmitted by means of body temperature. The sensor 2 collects the body temperature signal of the subject, so that the body temperature and blood oxygen saturation can be detected by only a single instrument.

Although the above-mentioned finger-clamp oximeter can detect the body temperature and blood oxygen saturation of a single instrument, the finger-clamp oximeter inevitably has the following problems in practical applications:

The sensor interface 10 is detached, so the plugging method is not stable, and it is easy to cause problems such as poor contact and wear over time, thereby bringing certain accuracy to the detection accuracy and service life of the finger-clip oximeter. Bad effects.
