Problems solved by technology

Among the above sensors, finger clip and finger cot blood oxygen saturation sensors can be used repeatedly, but they are unreliable fixed on the finger and are easy to fall off during sleep; sticky blood oxygen saturation sensors are not easy to locate and easy to use. Inaccurate alignment, in addition, high cost for one-time use
The wrapped sensor can be reused, but it is not easy to operate by one person when using it, and it is not easy to align when fixed
Therefore, these types of sensors are not very suitable for patients with sleep apnea monitoring

Embodiment Construction

[0057] In order to further illustrate the technical means adopted by the present invention and its effects, the following describes in detail in conjunction with preferred embodiments of the present invention and accompanying drawings.

[0058] see Figure 1 to Figure 3 The present invention firstly provides a finger-pulp blood oxygen saturation sensor. The finger-pulp blood oxygen saturation sensor 10 includes a blood oxygen probe 1, a wire 3 electrically connected to the blood oxygen probe 1 at one end, and another wire 3 connected to the wire 3. Connector 5 with one end electrically connected. The blood oxygen probe 1 is used for sensing blood oxygen saturation, and the connector 5 is used for signal transmission.

[0059] Please also see Figure 4 to Figure 8 , the blood oxygen probe 1 includes a finger ring 11, a flexible cable 13 installed inside the finger ring 11 and electrically connected to one end of the wire 3, a light emitting tube installed inside the finger ri...

Abstract

The invention provides a finger pulp type blood oxygen saturation degree sensor and a measuring system thereof. The finger pulp type blood oxygen saturation degree sensor comprises a blood oxygen probe (1), a wire (3) and a connector (5). The blood oxygen probe (1) comprises a finger ring (11), a soft flat cable (13) installed on the inner side of the finger ring (11), a light-emitting tube (15) and a receiving tube (17), wherein the light-emitting tube (15) and the receiving tube (17) are installed on the inner side of the finger ring (11) and electrically connected with the soft flat cable (13). The two ends of the finger ring (11) are communicated so that one finger can extend out of the finger ring (11). When the blood oxygen saturation degree sensor (10) is worn on the finger, the finger ring (11) is matched with the finger in shape and fully wraps the finger, and the length of the finger ring (11) does not exceed one section of the finger. The light-emitting tube (15) and the receiving tube (17) make contact with the two sides of the finger pulp respectively. The finger pulp type blood oxygen saturation degree sensor is convenient to wear, firm, not prone to falling, low in cost, and particularly suitable for monitoring breath during sleep.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a finger-pulp type blood oxygen saturation sensor and a measurement system thereof. Background technique [0002] Blood oxygen saturation is one of the key clinical physiological parameters. At present, the blood oxygen saturation measuring instrument applying the photoelectric principle is generally used for measurement, wherein the blood oxygen saturation sensor is the core component of the blood oxygen saturation measuring instrument. [0003] When using the blood oxygen saturation measuring instrument, the common measurement part is the finger, and the common use part of the blood oxygen saturation sensor is the finger, and the sensors used for the finger part are generally transmissive, that is, the light-emitting tube and the receiving tube respectively contact the nail and the Finger pulp, the light emitted by the light-emitting tube is received by the receiving tube on the...
