[0032] In addition, terms such as "first" and "second" are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0033] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0034] Please refer to Figures 1 to 6 for an explanation of the pulse oximeter provided by the present invention.

[0035] The pulse oximeter includes an upper shell assembly 1 and a lower shell assembly 2. The upper shell assembly 1 includes an upper shell 11, a first positioning post 12, and a first rubber pad 13. The lower shell assembly 2 includes a lower shell 21, a second positioning post 22, and a second rubber pad 23. The upper shell 11 is provided with a first receiving groove 14. The first positioning post 12 is installed on the groove wall of the first receiving groove 14 and is used to position the first rubber pad 13. The first rubber pad 13 is in interference fit with the first receiving groove 14. The lower shell 21 is provided with a second receiving groove 24. The second positioning post 22 is installed on the groove wall of the second receiving groove 24 and is used to position the second rubber pad 23. The second rubber pad 23 is in interference fit with the second receiving groove 24.

[0036] It can be understood that the first positioning post 12 of the pulse oximeter is installed on the groove wall of the first receiving groove 14 and is used to position the first rubber pad 13. The first rubber pad 13 is in interference fit with the first receiving groove 14. The second positioning post 22 is installed on the groove wall of the second receiving groove 24 and is used to position the second rubber pad 23. The second rubber pad 23 is in interference fit with the second receiving groove 24, so that the first rubber pad 13 and the second rubber pad 23 can be directly pulled out from the upper shell 11 and the lower shell 21, and then reinstalled after cleaning, which is convenient and fast to use.

[0037] It should be noted that the first rubber pad 13 is closely fitted with the edge of the first receiving groove 14, so that the first rubber pad 13 can be in interference fit with the first receiving groove 14, so that the first rubber pad 13 can be installed on the upper shell 11. The second rubber pad 23 is closely fitted with the edge of the second receiving groove 24, so that the second rubber pad 23 can be in interference fit with the second receiving groove 24, so that the second rubber pad 23 can be installed on the lower shell 21.

[0038] In an embodiment, as Figures 2 to 4 shown, the pulse oximeter further includes a torsion spring 3. The upper shell 11 is provided with a rotating shaft 15 and a first clamping position 16, and the lower shell 21 is provided with a rotating groove 25 and a second clamping position 26. The rotating shaft 15 is rotatably connected in the rotating groove 25. One end of the torsion spring 3 is clamped in the first clamping position 16, and the other end is clamped in the second clamping position 26 to clamp the finger between the first rubber pad 13 and the second rubber pad 23. During the process of the upper shell 11 rotating relative to the lower shell 21, the upper shell 11 drives the rotating shaft 15 to rotate in the rotating groove 25. The upper shell 11 and the lower shell 21 overcome the pulling force of the torsion spring 3, so that the upper shell 11 can move relative to the lower shell 21. After the finger is placed between the first rubber pad 13 and the second rubber pad 23, the upper shell 11 is released, and the pulling force of the torsion spring 3 pulls the upper shell 11 and the lower shell 21, so that the finger is clamped between the first rubber pad 13 and the second rubber pad 23.

[0039] The torsion spring 3 includes a torsion body, and a first body and a second body connected to the torsion body. The first body is clamped in the first clamping position 16, and the second body is clamped in the second clamping position 26.

[0040] In this embodiment, the upper shell 11 is provided with a first abutting surface 100, and the lower shell 21 is provided with a second abutting surface 200. The first abutting surface 100 abuts against the second abutting surface 200. The upper shell 11 and the lower shell 21 are limited in the lateral direction, so that the upper shell 11 and the lower shell 21 rotate at a limited angle.

[0041] In an embodiment, as Figure 2 and Figure 4As shown, the upper shell assembly 1 further includes a main board 17, and the lower shell assembly 2 further includes an adapter board 27. The main board 17 is installed in the first receiving groove 14, and the adapter board 27 is installed in the second receiving groove 24. The first rubber pad 13 is provided with a first transparent window 131, and the second rubber pad 23 is provided with a second transparent window 231. The light emitted by the first light-emitting diode on the main board 17 passes through the first transparent window 131 and is emitted to the second light-emitting diode on the adapter board 27 through the second transparent window 231. Specifically, the first light-emitting diode on the main board 17 is equivalent to the transmitting end, and the second light-emitting diode on the adapter board 27 is equivalent to the receiving end. The first light-emitting diode and the second light-emitting diode interact to measure the blood oxygen content of the swollen finger using the optoelectronic principle. By providing the first transparent window 131 and the second transparent window 231, light can penetrate the finger. The rest of the first rubber pad 13 and the second rubber pad 23 is black to prevent external light from penetrating into the upper shell 11 and the lower shell 21 and affecting the measurement effect.

[0042] In this embodiment, the first rubber pad 13 is provided with a first arc surface 132, and the second rubber pad 23 is provided with a second arc surface 232. By providing the first arc surface 132 and the second arc surface 232, the first rubber pad 13 and the second rubber pad 23 can better fit the finger.

[0043] In one embodiment, as Figure 2 shown, the upper shell assembly 1 further includes a display screen 19 and a bracket 18. The display screen 19 is installed on the main board 17 through the bracket 18 and is exposed outside the upper shell 11. In this way, the display screen 19 can be installed on the main board 17. The display screen 19 is exposed outside the upper shell 11, enabling the user to observe the information on the display screen 19.

[0044] In this embodiment, the upper shell 11 assembly further includes an upper shell cover plate 194. The upper shell cover plate 194 is disposed in the first receiving cavity and is engaged with the upper shell 11. The upper shell cover plate 194 is used to protect the main board 17. The upper shell cover plate 194 is provided with a first avoidance groove for avoiding the light emission of the first light-emitting diode on the main board 17. The upper shell cover plate 194 is further provided with a second avoidance groove for avoiding the first positioning post 12.

[0045] Furthermore, the upper shell assembly 1 further includes a panel 191. The panel 191 covers the upper shell 11. The panel 191 is provided with a display area 192 for displaying the display screen 19. By providing the panel 191, it is used to protect the display screen 19.

[0046] Furthermore, the upper shell assembly 1 further includes a button 193. The button 193 is electrically connected to the main board 17 and is exposed outside the panel 191. By providing the button 193, the button 193 can control and select the functions of the pulse oximeter.

[0047] In one embodiment, continuing as Figures 2 to 5As shown, the lower shell assembly 2 further includes a shrapnel 281 and a battery 28. The battery 28 is electrically connected to the adapter board 27 through the shrapnel 281. Specifically, there are two shrapnel 281, which are fixed from different surfaces of the lower shell 21 respectively. The welding ends of the shrapnel 281 are inserted at the welding holes of the adapter board 27, so that the shrapnel 281 can be welded to the adapter board 27. The battery 28 can supply power to the adapter board 27.

[0048] Furthermore, the lower shell 21 is further provided with an arc-shaped groove 212. The battery 28 is arranged in the arc-shaped groove 212 for limiting the battery 28. During the actual use of the product, for example, when the blood oxygen meter is held on the finger and the finger knocks on the table, under the impact of the product and the table with a non-destructive force, the display screen 19 may have a situation of power-off and restart. The design of the arc-shaped groove 212 clamps the battery 28 into a limited space to prevent shaking, thus avoiding the above-mentioned power-off and restart situation.

[0049] Furthermore, the lower shell assembly 2 is further provided with a lower shell cover plate 296. The lower shell cover plate 296 is snap-fitted to the lower shell 21 and covers a part of the second receiving groove 24.

[0050] In an embodiment, as Figure 5 and Figure 6 shown, the lower shell assembly 2 further includes a battery cover 29 and a limiting arm 291. The lower shell 21 is provided with a limiting groove 211. The battery cover 29 includes a first end 292 and a second end 293 opposite to the first end 292. The limiting arm 291 gradually inclines from the first end 292 to the second end 293, and the limiting arm 291 abuts in the limiting groove 211. Specifically, the limiting arm 291 gradually inclines from the first end 292 to the second end 293. That is to say, the limiting arm 291 and the limiting groove 211 are not in a straight-line design (wedge-shaped surface), so that during the process of the battery cover 29 being snapped onto the lower shell 21, the lateral gap on both sides becomes smaller as it is snapped deeper. After being pushed to the appropriate position, the lateral gap is zero, preventing a shaking gap from being generated between the battery cover 29 and the lower shell 21. When the hand pushes the battery cover 29 outwards, only a little force is needed, and the snap position of the battery cover 29 is unfastened. As the battery cover 29 is pushed backwards, the lateral gap changes from zero to a larger gap, so as to take out the battery cover 29.

[0051] In this embodiment, the limiting arm 291 is provided with a limiting protrusion, and the limiting protrusion abuts against the groove wall of the limiting groove 211.

[0052] Furthermore, the battery cover 29 is provided with a first snap position 294 and a second snap position 295. The first snap position 294 is arranged at the first end 292 and is snap-fitted with the lower shell 21. The second snap position 295 is arranged at the second end 293 and is snap-fitted with the lower shell 21. By setting the first snap position 294 and the second snap position 295, the battery cover 29 can be stably snap-fitted onto the lower shell 21.

[0053] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0054] The above-disclosed is only the preferred embodiment of the present utility model, and of course, it cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made according to the claims of the present utility model still fall within the scope covered by the present utility model.
