[0029] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0030] Embodiment 1: A disposable blood oxygen sensor that prevents accidental disconnection, such as Figure 1-Figure 4 As shown, it includes a finger positioning member 1, a covering component 2, a docking plug 3 and a docking component 4. The finger positioning member 1 includes a finger placement plate 11, a Velcro Ⅰ 12 and a finger positioning plate 13. Velcro Ⅰ 12 is symmetrically arranged at the bottom of the finger placement plate 11, and the adhesive surface of the Velcro Ⅰ 12 faces the lower side. The finger placement plate 11 is provided with a finger positioning plate 13 on the front side. The finger positioning plate 13 has a tapered surface extending toward the front side for positioning the finger. The covering component 2 includes a wrapping tape 21, a Velcro Ⅱ 22 and an adhesive tape Ⅰ 23. Velcro II 22 is symmetrically provided in the finger placement plate 11 for sliding front and back. Velcro II 22 can slide left and right in the finger placement plate 11. Velcro II 22 is bent downward and adhered to Velcro I 12. A wrapping belt 21 is connected to the left side of Velcro II 22. Adhesive belt I 23 is symmetrically provided front and back on the left side of the wrapping belt 21. Grooves for fixing sensors and strip holes for ventilation are provided on the finger placement plate 11 and the wrapping belt 21. The docking plug 3 and the finger placement plate 11 are detachably connected through the docking assembly 4.

[0031] like Figure 5 As shown, the docking assembly 4 includes a docking joint I 41, a docking joint II 42, a clamping block 44 and a spring 45. A docking joint I 41 is provided at the middle of the rear side of the finger placement plate 11, and a clamping groove 43 is symmetrically opened on the outer surface of the docking joint I 41 from top to bottom. A docking joint II 42 is provided at the end of the docking plug 3, and a clamping block 44 is rotatably provided at the front side of the docking joint II 42. A spring 45 is connected between the rear side of the clamping block 44 and the docking joint II 42. The front end of the clamping block 44 is clamped in the clamping groove 43, and the front end of the clamping block 44 can be detached from the clamping groove 43 by pressing the rear end of the clamping block 44.

[0032] When it is necessary to monitor the patient's blood oxygen saturation and pulse rate, first fix the corresponding sensor in the grooves on the finger placement plate 11 and the wrapping belt 21, then separate the Velcro I 12 and the Velcro II 22 according to the size of the human finger, and adjust the position of the wrapping belt 21 to the left or right according to the strap of the human finger, so that when the wrapping belt 21 wraps the finger, the two sensors can overlap in the vertical direction. After the position of the wrapping belt 21 is adjusted, the Velcro I 12 and the Velcro II 22 are glued together again, and then the finger is placed on the position of the finger positioning plate 13, and the back of the finger is fitted with the top of the finger positioning plate 13, and then the wrapping belt 21 is wrapped around the human finger until the adhesive tape I 23 is fitted with the wrapping belt 21. The person's fingers are fixed, and then the docking plug 3 is connected to the instrument to start monitoring the patient's blood oxygen saturation and pulse rate. Because there are strip holes for ventilation on the finger placement plate 11 and the wrapping belt 21, the heat can be dissipated from the person's fingers to prevent sweating of the person's fingers, which causes the wrapping belt 21 to loosen and affect the detection results. After the monitoring is completed, the adhesive tape I 23 is first loosened, and then the wrapping belt 21 is loosened, the patient's fingers are taken down, and then the rear side of the clamping block 44 is pressed downward, the spring 45 is compressed, and the front side of the clamping block 44 leaves the clamping groove 43, and then the docking joint I 41 and the docking joint II 42 are separated. At this time, the finger positioning member 1 can be replaced. In this way, the docking plug 3 can continue to be used, saving materials.

[0033] Embodiment 2: Based on embodiment 1, Figure 6 As shown, it also includes a finger positioning sleeve 5. The finger positioning sleeve 5 is arranged on the finger placement plate 11 at the finger positioning plate 13. The finger positioning sleeve 5 includes a finger sleeve 51 and a sponge 52. The finger sleeve 51 is fixedly installed on the outer side of the finger positioning plate 13. The finger positioning sleeve 5 is annular. The sponge 52 is arranged on the upper side of the finger sleeve 51. The cross-section of the sponge 52 is an inverted V shape.

[0034] like Figure 6 As shown, a finger fixing part 6 is also included. The finger fixing part 6 is arranged on the front side of the finger sleeve 51. The finger fixing part 6 includes a finger clamping plate 61 and a flexible pad 62. The finger clamping plate 61 is symmetrically arranged on the front side of the finger sleeve 51, and a flexible pad 62 is arranged on the inner side of the finger clamping plate 61 to protect human fingers.

[0035] like Figure 7 As shown, it also includes an anti-pressure piece 7, which is a finger model. The finger model is sleeved in the finger sleeve 51. The finger model can prevent the device from being transported or placed.

[0036] like Figure 8As shown, a reinforcement component 8 is also included. The bottom of the finger placement plate 11 is provided with a reinforcement component 8 extending toward the front side. The reinforcement component 8 includes a connecting plate 81, an annular belt 82 and an adhesive tape II 83. The connecting plates 81 are symmetrically arranged at the bottom of the finger placement plate 11. An annular belt 82 is connected between the front ends of the connecting plates 81. An adhesive tape II 83 is arranged at one end of the annular belt 82.

[0037] When placing a finger on the finger placement plate 11 for monitoring, first pull the finger model out of the finger sleeve 51. The finger model can prevent the finger sleeve 51 from being squeezed and deformed during transportation or placement of the device. The finger passes through the finger sleeve 51, and the sponge 52 allows the finger sleeve 51 to have a buffering space, so that the finger sleeve 51 can be suitable for fingers of different sizes. Then, the finger clamping plate 61 is attached to the finger. The flexible pad 62 allows the finger clamping plate 61 to have a buffering space to prevent the finger clamping plate 61 from damaging the finger. After the finger is placed, the annular belt 82 is put on the front side of the finger joint, and the adhesive tape II 83 is attached. In this way, the finger placement plate 11 and its components can be better fixed to the finger to prevent the detection result from being deviated due to accidental touch.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
