Description

Technical Field

[0001] The present invention belongs to the medical field, and particularly relates to a disposable blood oxygen probe that prevents accidental touch and disconnection. Background Art

[0002] A disposable blood oxygen probe is a medical device specifically designed to be discarded after single use, mainly used for non-invasive monitoring of a patient's blood oxygen saturation (SpO2) and pulse rate. Such probes are typically used in situations where strict prevention of cross-infection is required, such as in intensive care units (ICUs), emergency rooms, or operating rooms in hospitals.

[0003] For existing disposable blood oxygen probes, they are usually fixed by tape. Fixing with tape easily causes sweating on the fingers, which in turn causes the tape to lose its adhesiveness. In this case, if affected by external forces, the opposite sensors are likely to be displaced, resulting in inaccurate detection results. At the same time, the finger sizes of different patients are inconsistent. Before the sensor is put on a person's finger, the position of the sensor needs to be adjusted well. With the fixing method using tape, the position of the sensor is not easy to adjust.

[0004] Therefore, there is an urgent need to develop a disposable blood oxygen probe that can ventilate, is convenient to adjust, and prevents accidental touch and disconnection. Summary of the Invention

[0005] To overcome the above-mentioned disadvantages of the prior art, the present invention provides a disposable blood oxygen probe that can ventilate, is convenient to adjust, and prevents accidental touch and disconnection.

[0006] A disposable blood oxygen probe that prevents accidental touch and disconnection includes a finger positioning member, a covering assembly, a docking plug, and a docking component. The finger positioning member includes a finger placement plate and Velcro I. Velcro I is symmetrically arranged at the front and back of the bottom of the finger placement plate. The covering assembly includes a wrapping band, Velcro II, and an adhesive tape I. Velcro II is symmetrically and slidably arranged inside the finger placement plate in the front and back directions. Velcro II bends downward and is bonded to Velcro I. The left side of Velcro II is connected to the wrapping band. The adhesive tape I is symmetrically arranged at the front and back of the left side surface of the wrapping band. Slots for fixing the sensor and strip-shaped holes for ventilation are provided on both the finger placement plate and the wrapping band. The docking plug is detachably connected to the finger placement plate through the docking component.

[0007] More preferably, the finger positioning member further includes a finger positioning plate, and the finger positioning plate is arranged on the front side surface of the finger placement plate.

[0008] More preferably, the docking component includes a docking head Ⅰ, a docking head Ⅱ, a clamping block and a spring.

Therefore, it should not be construed as a limitation to the present application.

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

[0030] Embodiment 1: A disposable blood oxygen probe that prevents accidental touch and disconnection, as Figures 1 - 4 shown, includes a finger positioning member 1, a covering assembly 2, a docking plug 3 and a docking assembly 4. The finger positioning member 1 includes a finger placement plate 11, a magic tape I 12 and a finger positioning plate 13. Magic tapes I 12 are symmetrically arranged at the front and rear of the bottom of the finger placement plate 11, and the adhesive surface of the magic tape I 12 faces downward. A finger positioning plate 13 is arranged on the front side of the finger placement plate 11, and a tapered surface extending forward is provided on the finger positioning plate 13 to position the finger. The covering assembly 2 includes a wrapping band 21, a magic tape II 22 and a sticking tape I 23. Magic tapes II 22 are symmetrically and slidably arranged inside the finger placement plate 11 in the front and rear directions. The magic tape II 22 can slide left and right inside the finger placement plate 11. The magic tape II 22 bends downward and is bonded to the magic tape I 12. A wrapping band 21 is connected to the left side of the magic tape II 22. Sticking tapes I 23 are symmetrically arranged at the front and rear of the left side surface of the wrapping band 21. Slots for fixing the sensor and strip-shaped holes for ventilation are provided on both the finger placement plate 11 and the wrapping band 21. The docking plug 3 is detachably connected to the finger placement plate 11 through the docking assembly 4.

[0031] As Figure 5 shown, the docking assembly 4 includes a docking head I 41, a docking head II 42, a clamping block 44 and a spring 45. A docking head I 41 is arranged in the middle of the rear side of the finger placement plate 11. Clamping grooves 43 are symmetrically arranged on the outer surface of the docking head I 41 in the up and down directions. A docking head II 42 is arranged at the end of the docking plug 3. A clamping block 44 is rotatably arranged on the front side of the docking head II 42. A spring 45 is connected between the rear side of the clamping block 44 and the docking head II 42. The front end of the clamping block 44 is stuck in the clamping groove 43. By pressing the rear end of the clamping block 44, the front end of the clamping block 44 can be disengaged from the clamping groove 43.

[0032] When it is necessary to monitor the blood oxygen saturation and pulse rate of a patient, first fix the transmissive sensor in the grooves on the finger placement plate 11 and the wrapping band 21. Then, according to the size of the human finger, separate the magic tape I 12 and the magic tape II 22, and move the wrapping band 21 left or right to adjust its position according to the size of the human finger, so that when the wrapping band 21 wraps the finger, the two sensors can coincide in the vertical direction. After the position of the wrapping band 21 is adjusted, bond the magic tape I 12 and the magic tape II 22 again. Then place the finger at the position of the finger positioning plate 13, with the back of the finger fitting against the top of the finger positioning plate 13. Then wrap the wrapping band 21 around the human finger until the adhesive tape I 23 fits against the wrapping band 21 to fix the human finger. Then connect the docking plug 3 to the instrument to start monitoring the blood oxygen saturation and pulse rate of the patient. Since there are strip-shaped holes for ventilation on the finger placement plate 11 and the wrapping band 21, heat dissipation can be carried out on the human finger to prevent the human finger from sweating, which may cause the wrapping band 21 to loosen and affect the detection result. After the monitoring is completed, first loosen the adhesive tape I 23, then loosen the wrapping band 21, and remove the patient's finger. Then press the rear side of the clamping block 44 downward, the spring 45 is compressed, the front side of the clamping block 44 leaves the clamping groove 43, and then separate the docking head I 41 and the docking head II 42. At this time, the finger positioning member 1 can be replaced. In this way, the docking plug 3 can still be used, saving materials.

[0033] Embodiment 2: On the basis of Embodiment 1, as Figure 6 shown, it further includes a finger positioning sleeve 5. A finger positioning sleeve 5 is provided 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 outside of the finger positioning plate 13. The finger positioning sleeve 5 is annular. A sponge 52 is provided on the inner upper side of the finger sleeve 51, and the cross-section of the sponge 52 is an inverted V shape.

[0034] As Figure 6 shown, it further includes a finger fixing member 6. A finger fixing member 6 is provided on the front side of the finger sleeve 51. The finger fixing member 6 includes a finger clamping plate 61 and a flexible pad 62. Finger clamping plates 61 are symmetrically provided on the front side of the finger sleeve 51, and a flexible pad 62 is provided on the inner side surface of the finger clamping plate 61 to protect the human finger.

[0035] As Figure 7 shown, it further includes a pressure prevention member 7. The pressure prevention member 7 is a finger model. The finger model is sleeved in the finger sleeve 51. The finger model can prevent the device during transportation or placement.

[0036] As Figure 8As shown, it further includes a reinforcement component 8. A reinforcement component 8 extending forward is provided at the bottom of the finger placement plate 11. The reinforcement component 8 includes a connecting plate 81, an annular belt 82, and an adhesive tape II 83. Connecting plates 81 are symmetrically provided 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 provided at one end of the annular belt 82.

[0037] When the finger is placed on the finger placement plate 11 for monitoring, first, the finger model is pulled out of the finger sleeve 51. The finger model can prevent the finger sleeve 51 from being squeezed and deformed during the 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 buffer space, so that the finger sleeve 51 can accommodate fingers of different sizes. Subsequently, the finger clamping plate 61 is attached to the finger. The flexible pad 62 allows the finger clamping plate 61 to have a buffer 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 pasted well. In this way, the finger placement plate 11 and its components can be better fixed to the finger, preventing the detection result from being deviated due to accidental touch.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
