Embodiment Construction

[0041] 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.

[0042] see Figure 1 to Figure 5 , is the first embodiment of the ring-shaped blood oxygen saturation measuring instrument of the present invention. The ring-shaped blood oxygen saturation measuring instrument includes a finger cover 1 and a body 3 installed in the finger cover 1 .

[0043] The finger cot 1 is used to wear the body 3 on the finger, and the body 3 is used to measure blood oxygen saturation. The body 3 can be easily installed and disassembled relative to the finger cot 1 , and the ring-shaped blood oxygen saturation measuring instrument can adapt to fingers of different thicknesses for measurement by changing the finger cot 1 of different sizes.

[0044] Such as Figure 6 to Figure 9 As shown, the shape of the finger cot 1 is...

Abstract

The invention provides a ring type oxyhemoglobin saturation measuring instrument. The ring type oxyhemoglobin saturation measuring instrument comprises a finger sleeve (1) and a body (3) mounted in the finger sleeve (1). The finger sleeve (1) is used for enabling the body (3) to be worn on the finger, and the body (3) is used for measuring oxyhemoglobin saturation. The finger sleeve (1) is further provided with an elastic structure capable of being stretched. The ring type oxyhemoglobin saturation measuring instrument can be suitable for fingers of different thicknesses for measuring by replacing the finger sleeves (1) of different sizes, wearing is convenient, disengaging can not happen easily, and the ring type oxyhemoglobin saturation measuring instrument is suitable for being continuously worn and used for a long time.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a ring-shaped blood oxygen saturation measuring instrument. Background technique [0002] Blood oxygen saturation is one of the key clinical physiological parameters. At present, it is generally measured by a blood oxygen saturation measuring instrument that applies the photoelectric principle. When using a blood oxygen saturation measuring instrument, the common measurement site is the finger. The sensors used for the finger are generally transmissive, that is, the light-emitting tube and the receiving tube are in contact with the nail and finger pulp respectively, and the light emitted by the light-emitting tube passes through the fingernail. It is received by the receiving tube on the pulp side of the finger. Since there are many blood vessels under the nail in the finger and it is easy to measure, the measurement site on the finger is mostly at the nail. The finger clip type ...
