The light transmission intensity of the hemoglobin tissue bed is measured by the light sensing device, the signal collected by the receiving end 112 is converted into a digital signal by the signal processing circuit and then sent to the microprocessor, and the microprocessor analyzes and calculates the digital signal to obtain the hemoglobin concentration and the blood oxygen saturation of the human body and finally displays the hemoglobin concentration and the blood oxygen saturation by the display panel.
(elastic part 30)
Fig. 5 is a front view showing the finger-worn blood oxygen monitoring device 1 with an elastic band according to the first embodiment of the present invention.
In some examples, the elastic portion 30 may be made of a rubber plastic material. Therefore, the elastic rubber has better elasticity. Specifically, the rubber-plastic material may be, for example, isoprene rubber, butadiene rubber, styrene-butadiene rubber, nitrile rubber, chloroprene rubber, sodium butadiene rubber, ethylene-propylene rubber, butyl rubber, natural rubber, or the like.
In some examples, the elastic part 30 has a first elastic band 31 connected from the main body part 10 to the inside of the first clamping part 21, and a second elastic band 32 connected from the main body part 10 to the inside of the second clamping part 22. Therefore, the stress of each elastic belt can be more uniform.
In some examples, the elastic part 30 has a first elastic band 31 connected to the inside of the first clamping part 21 from a preset position of the main body part 10, and a second elastic band 32 connected to the inside of the second clamping part 22 from a preset position of the main body part 10. This enables the first elastic band 31 and the second elastic band 32 to have a common end point in the main body 10. In other examples, the first and second elastic bands 31 and 32 may also be connected between the first and second clamping portions 21 and 22 in an interlaced manner.
In some examples, the width of the first and second elastic bands 31 and 32 extends in the same direction as the width of the extension 20. Thereby, the finger can be conveniently put on the extension part 20.
In other examples, the elastic part 30 may include a plurality of elastic bands juxtaposed in an extending direction of the width of the extending part 20. This improves the adaptability of the elastic part 30 to the finger, and facilitates the finger movement.
In some examples, an end of the first elastic band 31 connected to the first grip part 21 may be disposed between the first window 23 and the body part 10, and an end of the second elastic band 32 connected to the second grip part 22 may be disposed between the second window 24 and the body part 10. This can prevent the first window 23 or the second window 24 from being blocked by the first elastic band 31 or the second elastic band 32.
In some examples, the first and second elastic belts 31, 32 may be in a tensioned state and the elastic transition 25 may be in a relaxed state. In this case, the first and second elastic bands 31, 32 in the tensioned state enable close contact of the fingers with the extension 20, while the elastic transition 25 in the relaxed state enables easy finger penetration through the extension 20, thereby enabling better fit of the fingers and the like with the extension 20.
[ second embodiment ]
Fig. 6 is a bottom oblique view of the finger-worn blood oxygen monitoring device 1 with an elastic band 33 according to the second embodiment of the present invention. Fig. 7 is a front view showing the finger-worn blood oxygen monitoring device 1 with the elastic band 33 according to the second embodiment of the present invention.

Thereby, the elastic band 33 can be provided between the first clip portion 21 and the second clip portion 22 so as to connect the first clip portion 21 and the second clip portion 22. That is, in the present embodiment, the elastic portion 30 includes one elastic band 33. In addition, in the present embodiment, the elastic transition section 25A may have a wave shape.
In some examples, one end of the elastic band 33 may be disposed between the first window 23 and the main body portion 10, and the other end of the elastic band 33 may be disposed between the second window 24 and the main body portion 10. This can prevent the elastic band 33 from blocking the first window 23 or the second window 24.
In some examples, the elastic belt 33 may be in a tensioned state and the elastic transition piece 25 may be in a relaxed state. In this case, the elastic band 33 in the tensioned state can bring a finger into close contact with the extension 20, while the elastic transition section 25A in the relaxed state can facilitate the finger to pass through the extension 20, thereby enabling a better fit of the finger or the like with the extension 20.
In some examples, the elastic band 33 divides the ring into a first space constituted by the main body portion 10 and a portion of the first clip portion 21 and a portion of the second clip portion 22, and a second space constituted by the elastic transition section 25A and another portion of the first clip portion 21 and another portion of the second clip portion 22, the first space being smaller than the second space. In this case, it can be ensured that the second space has a sufficient space for the finger to pass through, whereby wearing of the finger can be facilitated.
