Specific implementation

[0024] The technical scheme in the utility model is further explained below in combination with the drawings and embodiments.

[0025] As Figure 1 Indicated, the utility model discloses a blood oxygen saturation detection device, including first clamping plate 1 and second clamping plate 2, still including:

[0026] Two connecting plates 3 are arranged at the both sides of first clamping plate 1, and the both sides of second clamping plate 2 are all provided with installation slot 201, and connecting plate 3 is clamped in corresponding installation slot 201;

[0027] Fixing piece, slidingly arranged on the side surface of second clamping plate 2, and penetrating to the inside of installation slot 201, and clamped on the side surface of connecting plate 3, for fixing connecting plate 3 in installation slot 201.

[0028] In the embodiment of the utility model, first clamping plate 1 and second clamping plate 2 are parallelly arranged, and detection is carried out through transmission, and the light emitting tube is arranged on first clamping plate 1, and the receiving tube is arranged on second clamping plate 2, and the blood oxygen saturation can be calculated through the change of light absorption rate.Specifically, when detecting the blood oxygen saturation, the finger is inserted between first clamping plate 1 and second clamping plate 2, and first clamping plate 1 or second clamping plate 2 is directly pressed, so that first clamping plate 1 and second clamping plate 2 are close to each other, until first clamping plate 1 and second clamping plate 2 contact the finger and generate a certain pressure on the finger, and the first clamping plate 1 and the second clamping plate 2 can be directly fixed under the action of the fixing piece, and finally the blood oxygen saturation detection can be carried out.

[0029] The scheme is pressed to the finger through the mutual close mode of first clamping plate 1 and second clamping plate 2, as Figure 5As shown, the first clamp 1 and the second clamp 2 always apply force to the fingers in a parallel manner, so that the fingers can be subjected to pressure more evenly when they are clamped, rather than applying greater force only to the fingertips. This can reduce discomfort that may be caused by excessive local force. In addition, after adjustment, the first clamp 1 and the second clamp 2 can be directly fixed by the fastener without additional pressing force. They can also adapt to different finger sizes and ensure stability during clamping.

[0030] Based on the above solutions, such as Figure 2 and Figure 3 As shown, the second clamping plate 2 has a second limiting groove 203 on its side. The fixing member includes a movable block 4 that is slidably disposed in the second limiting groove 203 and a snap-fit ​​part 6 disposed in the movable block 4. The connecting plate 3 has a plurality of snap-fit ​​grooves 304, and the snap-fit ​​part 6 snaps into one of the snap-fit ​​grooves 304.

[0031] Specifically, when the first clamping plate 1 and the second clamping plate 2 are fixed by the fastener, the movable block 4 in the initial state is housed in the second limiting groove 203, so that the connecting plate 3 is not restricted when moving in the mounting groove 201. In use, when a finger presses the inside of the second clamping plate 2, the first clamping plate 1 is pressed, causing the first clamping plate 1 to drive the connecting plate 3 to move in the mounting groove 201, thereby changing the distance between the first clamping plate 1 and the second clamping plate 2. When the first clamping plate 1 clamps the finger and there is a certain pressure, the movable block 4 is directly pushed, causing the movable block 4 to drive its set snap-fit ​​part 6 to snap into the corresponding snap-fit ​​groove 304 on the connecting plate 3, thereby completing the fixing of the first clamping plate 1 and implementing clamping.

[0032] Specifically, such as Figure 3 As shown, a first spring 5 is engaged in the second limiting groove 203. The first spring 5 abuts against the side of the movable block 4 and the second limiting groove 203. Under the action of the first spring 5, the initial state of the movable block 4 is changed, so that the movable block 4 is always under the pressure of the first spring 5 and is in the opening of the second limiting groove 203. The engaging part 6 is always engaged in the slot 304. When the connecting plate 3 is always limited, when adjusting the first clamping plate 1, the engaging part 6 is separated from the slot 304 by moving the movable block 4. After the adjustment is completed, the movable block 4 is released directly, so that it is automatically engaged in the corresponding slot 304 under the pressure of the first spring 5. The force of the first spring 5 increases the stability of the engaging part 6 in the slot 304, ensuring that the first clamping plate 1 will not move upward.

[0033] Specifically, to further facilitate operation, such as Figure 3As shown, the clamping portion 6 is wedge-shaped and has a guide slope 601 and a locking surface 602, and the clamping groove 304 is matched with the guide slope 601 and the locking surface 602; when the first clamping plate 1 and the second clamping plate 2 are clamped on the fingers, the movable block 4 does not need to be pushed, and the fingers are in the second clamping plate 2, the first clamping plate 1 is directly pressed downward, so that the first clamping plate 1 directly transmits the force to the clamping portion 6, the guide slope 601 of the clamping portion 6 is automatically retreated under the extrusion of the clamping groove 304 in the connecting plate 3, until the clamping portion 6 is clamped into the next clamping groove 304, and the pressing is continued until the fingers are stopped under the pressure of the first clamping plate 1, and the clamping portion 6 can be automatically moved into the corresponding clamping groove 304 under the action of the first spring 5, and the locking surface 602 is a plane, which can prevent the first clamping plate 1 from retreating under the action of the locking surface 602, so as to realize fixation, and the operation is more convenient.

[0034] Specifically, as shown in the drawings, Figure 3 The side surface of the second clamping plate 2 is provided with a push block 401, the push block 401 is provided with a plurality of anti-skid strips, and the movable block 4 is fixedly connected with the push block 401; after detection, the first clamping plate 1 cannot be moved under the action of the locking surface 602, at this time, the push block 401 is pushed to drive the movable block 4 to move in the second limiting groove 203, so that the clamping portion 6 is separated from the clamping groove 304, and the first clamping plate 1 is lifted upward to take out the fingers.

[0035] Moreover, the movable block 4 is provided with a limiting block 402, and the limiting block 402 is clamped on the side surface of the second limiting groove 203; the movable block 4 can be limited under the action of the limiting block 402, so as to ensure that the movable block 4 is always in the second limiting groove 203.

[0036] Based on the above scheme, as shown in the drawings, Figure 1 and Figure 2 The connecting plate 3 is also provided with a sliding block 301, the side surface of the mounting groove 201 is provided with a first limiting groove 202, the sliding block 301 is clamped in the first limiting groove 202, the first limiting groove 202 is provided with a second spring 302, and the second spring 302 is abutted between the side surface of the first limiting groove 202 and the sliding block 301.

[0037] During detection, the first clamping plate 1 moving downward will drive the sliding block 301 to move in the first limiting groove 202, so as to drive the second spring 302 in the first limiting groove 202 to be compressed, and when the detection is completed, the push block 401 can be directly pushed to release the limitation of the connecting plate 3, so that the sliding block 301 is automatically moved to the top end of the first limiting groove 202 under the reset of the second spring 302, so as to drive the first clamping plate 1 to reset, open the first clamping plate 1, and take out the fingers, which further simplifies the operation.

[0038] Moreover, the first limiting groove 202 is provided with a mounting rod 303, the sliding block 301 and the second spring 302 are sleeved on the mounting rod 303; under the action of the mounting rod 303, the sliding block 301 and the second spring 302 can be limited, and the radial bending of the second spring 302 can be avoided, so that the normal use of the second spring 302 is ensured.

[0039] Finally, it should be pointed out that the above embodiments are only used to illustrate the technical solutions of the present application and are not limiting. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the purpose and scope of the technical solutions of the present application, and all should be covered in the scope of the claims of the present application.
