Description

Technical Field

[0001] This utility model relates to the field of pulse oximeter technology, specifically a finger clip pulse oximeter with an anti-slip structure. Background Technology

[0002] The main indicators measured by a pulse oximeter are pulse rate, oxygen saturation, and perfusion index. Oxygen saturation is one of the most important basic data in clinical medicine. Oxygen saturation refers to the percentage of bound oxygen in the total blood volume relative to the total available oxygen volume.

[0003] Chinese Patent Publication No. CN221383533U discloses a finger-pressure pulse oximeter, including an upper clamp assembly and a lower clamp assembly. The upper clamp assembly includes an upper clamp housing, an upper support member, and an upper rubber pad. The lower clamp assembly includes a lower clamp housing and a lower rubber pad. The upper clamp housing and the lower clamp housing are hinged together. The upper rubber pad is connected to the upper clamp housing via the upper support member. The lower rubber pad is connected within the lower clamp housing and is distributed opposite to each other. The upper rubber pad has a first clamping groove, and the lower rubber pad has a second clamping groove distributed opposite to the first clamping groove. Flexible sensors are disposed on both the first and second clamping grooves. The use of the upper and lower rubber pads improves the comfort of clamping during use, and directly placing the flexible sensors on the upper and lower rubber pads improves the accuracy of detection.

[0004] The aforementioned patent ensures the fixation between the pulse oximeter and the finger by adding a rubber pad that contacts the finger, while also ensuring comfort. However, adding a rubber pad to the molded shell and support components increases the cost and complicates the assembly process. Utility Model Content

[0026] Example 1

[0027] Please see Figure 1 , 2 3. A finger clip pulse oximeter with an anti-slip structure includes a lower outer shell 1 and an upper outer shell 2. An inner shell 3 is provided on the opposing surfaces of the lower outer shell 1 and the upper outer shell 2. A plurality of anti-slip holes 4 are provided on the inner shell 3.

[0028] The inner shell 3 is made of plastic.

[0029] The working principle and beneficial effects of the above scheme are as follows:

[0030] This application eliminates the rubber pad and provides several anti-slip holes 4 on the inner shell 3. The anti-slip holes 4 on the inner shell 3 increase the friction with the fingers, ensuring the stability of the pulse oximeter when fixed to the fingers during use. The inner shell 3 with anti-slip holes 4 is made of plastic, ensuring comfort during use. During production, the plastic inner shell 3 and anti-slip holes 4 can be integrally molded, reducing subsequent assembly steps and simplifying assembly.

[0031] Example 2

[0032] Please see Figure 1 , 2 3. Based on embodiment 1, the inner shell 3 is connected to the lower outer shell 1 and the upper outer shell 2 by a snap fastener.

[0033] The working principle and beneficial effects of the above scheme are as follows:

[0034] The inner shell 3 is connected to the lower outer shell 1 and the upper outer shell 2 by snap-fit, which is convenient and quick.

[0035] Example 3

[0036] Please see Figure 1 , 2 3. Based on embodiments 1-2, a connecting shaft is provided between the lower outer shell 1 and the upper outer shell 2. The lower outer shell 1 and the upper outer shell 2 are rotatably connected to the connecting shaft, and a torsion spring is provided on the connecting shaft. The two ends of the torsion spring are respectively fixedly connected to the lower outer shell 1 and the upper outer shell 2.

[0037] The opposing surfaces at one end of the lower outer shell 1 and the upper outer shell 2 are each provided with a chamfered surface 5, and a retraction groove 6 is formed between the two sets of chamfered surfaces 5.

[0038] The working principle and beneficial effects of the above scheme are as follows:

[0039] Press one end of the lower outer shell 1 and the upper outer shell 2. Because this end is provided with a beveled surface 5, when it is pressed, the retraction groove 6 retracts, which will not affect the rotation of the lower outer shell 1 and the upper outer shell 2. The other end of the lower outer shell 1 and the upper outer shell 2 forms an opening that can place a finger and hold the finger under the action of the torsion spring.

[0040] Example 4

[0041] Please see Figure 1 , 2 3. Based on embodiments 1-3, the upper surface of the outer shell 2 is provided with a display screen 7.

[0042] A switch button 8 is provided on the upper surface of the upper outer casing 2.

[0043] A battery compartment 9 is provided on the lower outer casing 1.

[0044] Example 5

[0045] Please see Figure 1 , 2 3. Based on embodiments 1-4, a detection cavity for accommodating a finger is formed between the inner shell 3 connected to the lower outer shell 1 and the upper outer shell 2 respectively.

[0046] The detection cavity has a spindle-shaped cross-section in the direction perpendicular to the length of the inner shell 3.

[0047] The working principle and beneficial effects of the above scheme are as follows:

[0048] The spindle-shaped detection cavity that accommodates the finger fits the finger better, improving comfort.

[0049] Example 6

[0050] Please see Figure 4 , 5 Based on embodiments 1-5, a detection element 10 is provided on the inner shell 3 connected to the upper outer shell 2.

[0051] The detection element 10 is rotatably connected to the inner shell 3. A connecting block 12 is fixedly connected to the upper part of the detection element 10. At least half of a rotating ball 13 is embedded in the connecting block 12. The rotating ball 13 can rotate in the connecting block 12. A micro-motion rod 15 is fixedly connected to the upper end of the rotating ball 13.

[0052] A micro-motion cavity 14 is provided between the upper outer shell 2 and the inner shell 3. The micro-motion rod 15 is partially located in the micro-motion cavity 14 and can move within the micro-motion cavity 14.

[0053] The micro-motion rod 15 is fixedly connected to a first fixing plate 16 on its side wall. A first fixing rod 17 is fixedly connected to the first fixing plate 16. A first rotating plate 18 is rotatably connected to the first fixing rod 17. An insertion rod 24 fixed on the first rotating plate 18 is inserted into a slot 19. A spring 20 is provided between the slot 19 and the insertion rod 24. The slot 19 is fixedly connected to a second rotating plate 21. The second rotating plate 21 is rotatably connected to a second fixing rod 22. The second fixing rod 22 is fixedly connected to a second fixing plate 23. The second fixing plate 23 is fixedly connected to the inner wall of the micro-motion cavity 14.

[0054] The working principle and beneficial effects of the above scheme are as follows:

[0055] When the lower outer shell 1 and the upper outer shell 2 rotate and open relative to each other to clamp a finger, a large angle is formed between the two sets of inner shells 3. During clamping, this angle is not easy to fit with the finger, which can easily cause inaccurate detection. By rotating the detection element 10, and when the detection element 10 rotates, the spring 20 connected to the micro-motion rod 15 applies a certain pressure to the finger (when clamping the finger, the detection element 10 deflects upward, the micro-motion rod 15 moves upward, the slot 19 and the insertion rod 24 deflect, the height of the insertion rod 24 is higher than the slot 19, the spring 20 extends, and there is a pulling force on the slot 19 and the insertion rod 24. The vertical component of this pulling force acts on the micro-motion rod 15, thereby making the detection element 10 exert a certain pressure on the finger), the detection element 10 can fit with the finger, ensuring the accuracy of the detection.

[0056] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
