Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0035] Reference Figures 1 to 5 According to the embodiment of the present invention, the housing 100 of the oximeter is provided with a receiving hole 130 along the left and right directions (refer to Figure 3 ), the first flap door 110 and the second flap door 120 are arranged in parallel in the axial direction (i.e., in the left-right direction) in the accommodation hole 130. The first flap door 110 includes a plurality of first flaps 111 connected end to end and connected in a circle, and a first through hole 113 is formed in the first flap door 110 (refer to Figure 5 Similarly, the second flap door 120 includes a plurality of second flaps 121 connected end to end to form a circle, and a second via hole 123 is formed in the second flap door 120 (refer to Figure 4 ). The projection of the first slit 112 between two adjacent first flaps 111 along the axial direction of the receiving hole 130 falls on the second flap 121, that is, the first slit 112 and the second slit 122 between two adjacent second flaps 121 are staggered, and after light enters from the first slit 112, it will irradiate the second flap 121.

[0036] The first flap door 110 is provided with a first through hole 113, and the second flap door 120 is provided with a second through hole 123, so that a finger can easily pass through the first flap door 110 and the second flap door 120 and enter the receiving hole 130. Figure 7 ), the finger in the receiving hole 130 can be detected. In addition, after the user's finger blocks the first through hole 113 and the second through hole 123, only the first slit 112 can pass light, and the light passing through the first slit 112 is also blocked by the second petal 121, and the external light is effectively blocked outside the receiving hole 130.

[0037] In some embodiments of the present invention, the receiving hole 130 is a blind hole, and the first flap door 110 and the second flap door 120 are arranged at the opening end of the receiving hole 130. In this case, the housing 100 of the oximeter is suitable for being worn on the fingertips. After the housing 100 of the oximeter is sleeved on the fingertips, external light can only enter from the opening end of the receiving hole 130, so it is only necessary to arrange the first flap door 110 and the second flap door 120 at the opening end of the receiving hole 130.

[0038] Reference Figure 1 and Figure 3 In some embodiments of the present invention, the receiving hole 130 is a through hole, and the first flap door 110 and the second flap door 120 are provided at both ends of the receiving hole 130. At this time, the housing 100 of the oximeter can be put on the fingertips. After the housing 100 of the oximeter is put on the finger, light may enter from both ends of the receiving hole 130. Therefore, a first flap door 110 and a second flap door 120 need to be provided at the left end of the receiving hole 130, and a first flap door 110 and a second flap door 120 also need to be provided at the right end of the receiving hole 130. As a result, external light is blocked outside the receiving hole 130.

[0039] In some embodiments of the present invention, the diameter of the receiving hole 130 is adjustable. Due to age, gender or individual differences, people's fingers are thicker or thinner. By adjusting the diameter of the receiving hole 130, this situation can be adapted to meet the usage needs of different people.

[0040] Reference Figure 1 , Figure 3 and Figure 4 In some specific embodiments of the present invention, the side wall of the receiving hole 130 has an elastic pleated structure that can be opened or folded along the radial direction of the receiving hole 130. When not in use, the elastic pleated structure is in a contracted state, and the aperture of the receiving hole 130 is the smallest. When different fingers are inserted into the receiving hole 130, the elastic pleated structure can adapt to the fingers and open to the corresponding size to meet the use requirements. In addition, the elastic pleated structure has a wide range of size variations, is applicable to a wide range of people, and has strong versatility.

[0041] In another embodiment, the side wall of the receiving hole 130 may also be a common straight elastic structure. In this case, the diameter of the receiving hole 130 may also be variable and adjustable.

[0042] In some embodiments of the present invention, the shell 100 of the oximeter is made of silicone, which is a non-toxic and soft material that can meet the requirements of changing the diameter of the accommodating hole 130 and also meet safety requirements.

[0043] In another embodiment, the housing 100 of the oximeter may also be made of rubber.

The light emitter 210 and the light receiver 220 are arranged opposite to each other up and down, and are connected by wires wrapped in the housing 100 of the blood oxygen meter. After the light emitter 210 and the light receiver 220 are powered on, the finger inserted into the receiving hole 130 can be detected.

[0046] Since external light is effectively blocked by the first flap door 110 and the second flap door 120, the light received by the light receiver 220 is basically the light emitted by the light transmitter 210, the blood oxygen saturation detection is accurate, the light emitting power of the photoelectric sensor 200 does not need to be excessively increased, and energy is saved.
