Description

Technical Field

[0001] This invention relates to the field of medical disinfection technology, and more specifically to an automatic medical disinfection device. Background Technology

[0002] An electrocardiogram (ECG) lead is a circuit connection method in which electrodes are placed at different points on the body and connected to the positive and negative terminals of an ECG machine's galvanometer via lead wires to record an electrocardiogram (ECG). Currently, the widely adopted internationally accepted lead system is called the standard 12-lead system, which includes limb leads connected to the limbs and chest leads connected to the chest. The standard 12-lead system includes ten lead wires, each connected to an electrode. These electrodes are connected to four electrode bulbs and six electrode clips to acquire ECG data from the patient's limbs and chest cavity.

[0003] During use, the end of the lead wire closest to the electrode comes into contact with the patient's skin. Therefore, it is usually necessary to disinfect the lead wire after use to avoid cross-infection. Currently, most commercially available ECG lead wire disinfection devices are designed for portable ECG machines, which have fewer leads and separate leads. Disinfection devices for the lead wires commonly used in the standard 12-lead system are not common, and most of these devices do not disinfect the electrodes at the bottom of the lead wire sufficiently. In actual use, the electrodes have the longest contact time with the patient's skin, and the surface structure of the electrodes is more complex than that of the lead wires, requiring more thorough disinfection. Summary of the Invention

[0004] The present invention aims to provide an automatic medical disinfection device to solve the problem that existing disinfection devices do not disinfect electrodes sufficiently when disinfecting the lead wires of a conventional 12-lead system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a medical automatic disinfection device, comprising a disinfection plate, a disinfection nozzle, and a winding mechanism. The disinfection plate has several disinfection holes, and the disinfection nozzle is connected to a lifting mechanism, which enables the disinfection nozzle to unfold and retract. The winding mechanism includes a winding shaft with a locking part. The distance from each disinfection hole to the locking part is different.

[0006] The beneficial effects of this solution are as follows: a disinfection plate and a disinfection nozzle are installed inside the device. The disinfection holes on the disinfection plate disinfect the lead wires and the side of the motor. After the lifting mechanism controls the disinfection nozzle to unfold, it sprays disinfectant again on the electrode ends wound on the winding mechanism, so that the electrodes are fully disinfected and the disinfection effect is improved.

[0007] 1. A winding mechanism is set up to wind up the lead wires. Since the ten lead wires in a conventional 12-lead system are of the same length, after the lead wires are wound up, the ten electrodes will be arranged in sequence on the winding mechanism so that the disinfection nozzle can be unfolded and the electrodes can be further disinfected.

[0008] 2. The lifting mechanism enables the disinfection nozzle to unfold and retract. After the nozzle unfolds to spray disinfectant, it will retract again to avoid affecting the next disinfection operation of the disinfection device.

[0009] 3. After use, the lead wires may become partially tangled. Since all lead wires are the same length, by setting different distances from each sterilization hole to the locking part, the lead wires can be pulled out one by one from different sterilization holes, avoiding the risk of the lead wires getting tangled due to being wound and pulled from different angles at the same time.

[0010] Preferably, the disinfection holes are all inclined, each disinfection hole includes an inlet end and an outlet end, and the outlet end of each disinfection hole faces the snap-fit ​​part.

[0011] The beneficial effects of this solution are as follows: 1. All disinfection holes are set at an angle, and the outlet end of the disinfection hole faces the locking part on the winding shaft. During the winding process, all lead wires are wound towards the locking part. At this time, the angled disinfection holes can prevent the lead wires from being bent at a small angle at the outlet end. A small angle bend will damage the lead wires.

[0012] 2. The inclined disinfection hole has a larger inner wall area compared to the vertically set disinfection hole, which increases the number of soft bristles inside the disinfection hole, further improving the disinfection effect on the conductor and electrode surface.

[0013] Preferably, the disinfection plate has a liquid inlet channel, and all disinfection holes are connected to the liquid inlet channel. Each disinfection hole is provided with several soft bristles.

[0014] The beneficial effects of this solution are as follows: 1. Disinfectant is introduced into each disinfection hole through the liquid inlet channel to disinfect the lead wires and electrodes; the soft bristles draw up the disinfectant entering the disinfection hole and transfer it to the surface of the lead wires and electrodes to achieve disinfection by application.

[0015] 2. The soft bristles can be used to apply the coating to small-diameter leads and allow larger-diameter electrodes to pass through smoothly, while avoiding scratches and damage to the outer walls of the leads and electrodes during disinfection.

[0016] Preferably, the lifting mechanism includes a cylinder, an eccentric block, a fixed block, and a rotating shaft. One end of the rotating shaft is connected to the eccentric block, and the other end of the rotating shaft is connected to the disinfection nozzle. The rotating shaft is rotatably connected to the output shaft of the cylinder. The fixed block is provided with a groove, which is an inverted J-shape, and the eccentric block is slidably connected in the groove.

[0017] The beneficial effects of this design are as follows: The inverted J-shaped groove includes a vertical section, a turning section, and a horizontal section from bottom to top. The output shaft of the cylinder drives the disinfection nozzle to move up and down in the vertical direction, while the eccentric block enables the disinfection nozzle to move along the groove trajectory. When the output shaft of the cylinder extends and the eccentric block moves from bottom to top, under the action of the turning section, it changes from a vertical state located in the vertical section to a horizontal state located in the horizontal section. Then, through the rotating shaft, the disinfection nozzle rotates counterclockwise around the rotating shaft to the horizontal state, thus unfolding. When the output shaft of the cylinder retracts, the disinfection nozzle rotates clockwise around the rotating shaft to return to the retracted state. Thus, the unfolding and retracting operation of the disinfection nozzle is realized through a simple structure.

[0018] Preferably, the winding mechanism further includes a clamping block and a support block. One end of the winding shaft is rotatably connected to the support block, and the other end of the winding shaft is connected to a motor. The clamping block is sleeved on the winding shaft and is provided with a limiting part.

[0019] The beneficial effects of this solution are as follows: 1. The support block and motor provide support for both ends of the take-up shaft, and the rotation of the motor drives the take-up shaft to rotate slowly to achieve the winding of the guide wire.

[0020] 2. The clamping block is fitted onto the take-up shaft to press the surface of the take-up shaft, thereby pressing the lead wire wound on the take-up shaft to prevent the lead wire from unraveling after winding. The limiting part limits the winding of the lead wire to ensure that the lead wire is more neat after winding.

[0021] Preferably, it also includes a disinfectant storage tank, with the motor and support block both mounted on the disinfectant storage tank, and a tension spring between the bottom of the pressing block and the top of the disinfectant storage tank.

[0022] The beneficial effects of this solution are: 1. Under the action of the tension spring, the clamping block can always be in a state of pressing against the take-up shaft, thereby achieving the clamping of the guide wire wound on the take-up shaft.

[0023] 2. Both the motor and the support block are mounted on the disinfectant storage tank to improve the utilization of the tank space and reduce the overall size of the device.

[0024] 3. The disinfectant storage tank containing disinfectant has a certain weight, which can improve the stability of the entire tank and reduce vibration when the device is working. This avoids making the tank a heavy material to ensure the stability of the device during the disinfection process, which would increase the difficulty of handling. In this solution, the disinfectant in the storage tank can be removed to reduce the weight when the device needs to be moved.

[0025] Preferably, the clamping block is provided with several clamping grooves.

[0026] The beneficial effects of this solution are: the clamping groove can further limit the guide wire to ensure more neat winding.

[0027] Preferably, the disinfectant storage tank is connected to a first outlet pipe and a second outlet pipe. The first outlet pipe is connected to the inlet channel and is also connected to an infusion pump. The second outlet pipe is connected to the disinfection nozzle, and a push-button switch is provided between the second outlet pipe and the disinfection nozzle. The push-button switch is connected in a groove.

[0028] The beneficial effects of this solution are as follows: 1. Once the infusion pump is started, the disinfectant in the disinfectant storage tank can be pumped into the inlet channel through the first outlet pipe and then flow into the disinfection hole; the push-button switch is located in the horizontal part above the groove. When the slide bar moves upward and the push-button switch is squeezed, the disinfection nozzle sprays disinfectant outward, improving the automation of the device.

[0029] 2. The push-button switch is set in the groove and works in conjunction with the slide bar in the lifting mechanism to ensure that the push-button switch is only touched when the spray nozzle on the disinfection nozzle is aligned with the electrode, so as to avoid waste of disinfection solution.

[0030] Preferably, a double-control switch is provided above the clamping block, the motor and the infusion pump are connected to one wire of the double-control switch, the cylinder is connected to the other wire of the double-control switch, and a relay is provided between the cylinder and the double-control switch. The cylinder is connected to a two-position five-way valve.

[0031] The beneficial effects of this solution are as follows: During the winding process, when the winding shaft finishes winding the guide wire, the top of the clamping block can just touch the double-control switch. The double-control switch controls the motor and the infusion pump to cut off the power and stop working. At the same time, the cylinder is energized, and the cylinder output shaft extends, driving the disinfection nozzle to unfold during the upward process. It also sprays disinfectant solution onto the electrode end at the bottom of the guide wire after winding. The disinfectant solution enters from the bottom of the motor and thoroughly disinfects the electrode, improving the disinfection effect. Then, under the action of the relay energizing and delaying disconnection, the cylinder is de-energized again. At this time, under the action of the two-position five-way valve, the cylinder output shaft retracts again, driving the disinfection nozzle to move downward and retract at the same time, so as not to affect the use of the disinfection device next time. This process is completed by the cooperation of various components in the device without manual intervention, which greatly improves the automation and ease of use of the disinfection device and further enhances the automation of the device.

[0041] The following detailed description illustrates the specific implementation method:

[0042] The reference numerals in the accompanying drawings of the instruction manual include: box body 1, box door 11, handle 111, double control switch 12, start switch 13, take-up frame 14, disinfection plate 2, fixing plate 201, moving plate 202, disinfection hole 21, outlet end 211, inlet end 212, connection hole 22, disinfection nozzle 3, cylinder 31, connecting block 311, fixing block 32, groove 33, eccentric block 34, slide rod 341, rotating shaft 35, push button switch 36, take-up shaft 4, motor 41, annular groove 42, first locking groove 43, second locking groove 44, support block 45, pressing block 5, limiting part 51, tension spring 52, pressing groove 53, disinfectant storage tank 6, liquid filling port 61, lead wire 7, electrode 71, USB connector 72, main line 73, splitter board 74.

[0043] Example 1

[0044] Example 1 is basically as shown in the appendix. Figure 1-8 As shown, Figure 1 The illustrated automatic medical disinfection device includes a housing 1, a disinfection plate 2, a disinfection nozzle 3, and a winding mechanism. The disinfection plate 2, disinfection nozzle 3, and winding mechanism are all housed within the housing 1. Figure 2 As shown, the box 1 is a cuboid. A door 11 is hinged to the top of the box 1, and the door 11 has a handle 111. Closing the door 11 seals the box 1, ensuring that the device is not subject to secondary contamination during disinfection. A cable tray 14 is also glued to the bottom of the box 1 to facilitate the collection of the lead wire 7. Figure 8As shown, in this embodiment, the lead 7 to be disinfected is a conventional 12-lead electrocardiogram lead 7, including a main line 73 and ten lead lines 7. A USB connector 72 is connected to the main line 73. A splitter 74 is provided between the main line 73 and the lead lines 7. The ten lead lines 7 are separated from the main line 73 and made independent by the splitter 74. An electrode 71 is provided at the bottom of each lead line 7. The electrode 71 is connected to an electrode ball or an electrode clip to realize the connection to the human chest cavity and limbs.

[0045] Correspondingly, the disinfection plate 2 has ten disinfection holes 21. The upper end of each disinfection hole 21 is the outlet end 211, and the lower end is the inlet end 212. All disinfection holes 21 are cylindrical, and their diameters are larger than the diameter of the electrode 71 at the bottom of the lead wire 7, ensuring that the lead wire 7 and electrode 71 can smoothly pass through the disinfection holes 21. Figure 3 As shown, in this embodiment, the disinfection plate 2 is assembled from a fixed plate 201 and a movable plate 202. Specifically, multiple elongated protrusions (not shown in the figure) are integrally formed around the fixed plate 201, and a grooved edging (not shown in the figure) is integrally formed around the movable plate 202, with the protrusions fitting into the grooves of the edging. The edging and protrusions seal the movable plate 202 onto the fixed plate 201, completing the assembly. After assembly, a disinfection hole 21 is formed between the movable plate 202 and the fixed plate 201. The length of the fixed plate 201 is greater than the length of the movable plate 202, and the thickness of the fixed plate 201 is also greater than the thickness of the movable plate 202. Two-thirds of the disinfection hole 21 is located within the fixed plate 201.

[0046] The left end of the fixing plate 201 is welded and fixed to the inner wall of the housing 1. The fixing plate 201 has a liquid inlet channel (not shown in the figure) inside. There are four connecting holes 22 between the liquid inlet channel and each disinfection hole 21. The four connecting holes 22 are located at the four corners of the axial section of the disinfection hole 21 to ensure that the disinfectant can penetrate into all parts of the disinfection hole 21 more evenly, thereby improving the uniformity of disinfection of the lead wire 7 and the motor 41 passing through the disinfection hole 21. Several soft bristles are evenly fixed to the hole wall of each disinfection hole 21 by adhesive. The soft bristles draw up the disinfectant output from the connecting hole 22 and transfer it to the surface of the lead wire 7 and the electrode 71 to achieve coating disinfection. At the same time, the soft bristles can coat the lead wire 7 with a smaller diameter and allow the electrode 71 with a larger diameter to pass through smoothly, and avoid scratching or damaging the outer wall of the lead wire 7 and the electrode 71 when disinfecting them.

[0047] like Figure 4As shown, the disinfection nozzle 3 is generally elongated, with multiple spray holes evenly distributed on its lower half. The disinfection nozzle 3 is connected to a lifting mechanism, which enables the nozzle to extend and retract. The lifting mechanism includes a cylinder 31, an eccentric block 34, a fixed block 32, and a rotating shaft 35. One end of the rotating shaft 35 is welded and fixed below the eccentric block 34, and the other end is fixed to the top of the disinfection nozzle 3. The rotating shaft 35 is rotatably connected to the output shaft of the cylinder 31. Specifically, a connecting block 311 is threaded onto the top of the cylinder 31's output shaft. A cylindrical through-slot is formed in the connecting block 311, with an inner diameter larger than the diameter of the rotating shaft 35. The rotating shaft 35 is passed through the through-slot to achieve the rotatable connection between the rotating shaft 35 and the cylinder 31's output shaft. The fixing block 32 is welded and fixed to the inner wall of the box 1. A groove 33 is provided on the fixing block 32, and the groove 33 is inverted J-shaped. The inverted J-shaped groove 33 consists of a vertical part, a turning part and a horizontal part from bottom to top. A sliding rod 341 is welded and fixed above the eccentric block 34. A protrusion is connected to the other end of the sliding rod 341. The protrusion is slidably connected in the groove 33, so that the eccentric block 34 is slidably connected in the groove 33. The output shaft of cylinder 31 drives the disinfection nozzle 3 to move up and down in the vertical direction. The eccentric block 34 enables the disinfection nozzle 3 to move along the trajectory of the groove 33. When the output shaft of cylinder 31 extends and the eccentric block 34 moves from bottom to top, under the action of the steering part, it changes from a vertical state in the vertical part to a horizontal state in the horizontal part. Therefore, through the fixed connection of the rotating shaft 35, during this process, the disinfection nozzle 3 will rotate counterclockwise around the rotating shaft 35 to the horizontal state, thus unfolding. When the output shaft of cylinder 31 retracts, the disinfection nozzle 3 will rotate clockwise around the rotating shaft 35 to return to the retracted state. In this embodiment, the disinfection nozzle 3's transition from retraction to unfolding is... Figure 1 State transition Figure 7 state.

[0048] like Figure 1As shown, the box 1 also contains a disinfectant storage tank 6. The disinfectant storage tank 6 is made of transparent material to allow observation of the remaining amount of disinfectant stored in it. The disinfectant storage tank 6 has a filling port 61 with a sealing cap. Removing the sealing cap allows for adding disinfectant to the storage tank 6. The disinfectant storage tank 6 is connected to a first outlet pipe and a second outlet pipe, both of which are located inside the side wall of the box 1 to improve the cleanliness of the device and prevent tangling between the first and second outlet pipes and the connecting wire 7. The first outlet pipe is connected to the inlet channel and is also connected to an infusion pump. Activating the infusion pump pumps the disinfectant from the storage tank 6 into the inlet channel through the first outlet pipe, and then into the disinfection hole 21. The second outlet pipe is connected to the disinfection nozzle 3 and is also connected to a pump. A push-button switch 36 is located between the second outlet pipe and the disinfection nozzle 3. Figure 4 As shown, the push-button switch 36 is located in the horizontal part above the groove 33. When the slide bar 341 moves upward to the horizontal part, it will press the push-button switch 36. When the push-button switch 36 is pressed, the disinfection nozzle 3 will spray disinfectant outward. At the same time, the disinfection nozzle 3 is fully extended, and the spray hole is directly facing the bottom of the electrode 71. That is, the push-button switch 36 will only be touched and the disinfectant will be sprayed out when the spray hole on the disinfection nozzle 3 is aligned with the electrode 71, thus avoiding waste of disinfectant. The disinfectant storage tank 6 is placed inside the box body 1. This allows for easy observation of the remaining disinfectant while keeping the disinfectant in a shaded environment, preventing the disinfectant from being affected by exposure. At the same time, the disinfectant storage tank 6, which contains disinfectant, has a certain weight, which can improve the stability of the entire box body 1 and reduce vibration when the device is working. This avoids making the box body 1 a heavy material to ensure the stability of the device during the disinfection process, which would increase the difficulty of handling. In this solution, when the device needs to be moved, the disinfectant in the disinfectant storage tank 6 can be removed to reduce the weight.

[0049] like Figure 1 As shown, the winding mechanism is located on top of the disinfectant storage tank 6 to improve the space utilization of the tank 1 and reduce the overall size of the device. The winding mechanism includes a winding shaft 4, a clamping block 5, and a support block 45. The left end of the winding shaft 4 is detachably rotatably connected to the support block 45, and the right end of the winding shaft 4 is connected to a motor 41. A pad is provided below the motor 41 to make the output shaft of the motor 41 coaxial with the winding shaft 4. The output shaft of the motor 41 and the winding shaft 4 are detachably connected by a coupling. When the motor 41 is started, it drives the winding shaft 4 to rotate, winding up the guide wire 7. Figure 5As shown, the take-up spool 4 is provided with an annular groove 42, a first latching groove 43, and a second latching groove 44. The first latching groove 43 and the second latching groove 44 are opened in the annular groove 42, and the first latching groove 43 is closer to the center of the take-up spool 4 than the second latching groove 44. The first latching groove 43 realizes the latching and fixing of the USB connector 72. When the take-up spool 4 rotates, it will first wind the main cable 73 into the annular groove 42. After the main cable 73 is wound, the surface of the main cable 73 is exactly parallel to the surface of the take-up spool 4. Finally, the splitter plate 74 is latched into the second latching groove 44, filling the second latching groove 44 to facilitate the subsequent winding of the lead wire 7.

[0050] The clamping block 5 is positioned directly above the take-up shaft 4, as shown below. Figure 6 As shown, the clamping block 5 has limiting parts 51 on both sides, and each limiting part 51 has a moving hole. The moving hole ensures that the clamping block 5 can move upward relative to the winding shaft 4; the bottom of the clamping block 5 has an arc-shaped clamping surface that fits against the surface of the winding shaft 4; as shown Figure 1 As shown, a tension spring 52 is vertically fixed between the bottom end of the limiting part 51 and the top of the disinfectant storage tank 6. Under the tension of the tension spring 52, the clamping block 5 can always be in a state of pressing against the winding shaft 4, thereby clamping the guide wire 7 wound on the winding shaft 4 and preventing the guide wire 7 from unraveling after winding. The two limiting parts 51 limit the winding guide wire 7, so that the guide wire 7 is always located between the two limiting parts 51 when winding. In addition, in order to improve the winding effect of the guide wire 7, ten clamping grooves 53 are provided on the clamping surface of the clamping block 5. The groove walls of the clamping grooves 53 are respectively attached to the upper surface of different guide wires 7. The clamping grooves 53 can further limit the guide wire 7 to ensure more neat winding. Furthermore, the clamping block 5 is subjected to the tension of the two tension springs 52 below, which can prevent the electrodes 71 from being wound up when there is no other external interference. Since the ten lead wires 7 are all the same length, after the winding is completed, the ten electrodes 71 will be arranged in sequence outside the clamping block 5, so that the electrodes 71 can be further disinfected in the next step.

[0051] like Figure 1 As shown, after the winding mechanism is installed on the disinfectant storage tank 6, the distance between the disinfection holes 21 on the disinfection plate 2 and the winding shaft 4 decreases from left to right. Since all the lead wires 7 are of the same length, the lead wire 7 in the leftmost disinfection hole 21 will be pulled out first, and all ten lead wires 7 will be pulled out one by one from different disinfection holes 21. After use, some of the lead wires 7 may become tangled. If the lead wires 7 are wound and pulled from different angles at the same time during winding, the risk of tangling will increase. Setting them to be pulled out one by one can reduce the tangling situation. At the same time, as Figure 3As shown, all disinfection holes 21 are inclined, and the outlet end 211 of the disinfection hole 21 faces the take-up shaft 4. During the take-up process, all lead wires 7 face the take-up shaft 4 in the upper right corner. At this time, the inclined disinfection hole 21 can prevent the lead wire 7 from bending at a small angle when it passes through the outlet end 211. A small angle bend will damage the lead wire 7. In addition, the inner wall of the inclined disinfection hole 21 has a larger area than that of the vertically set disinfection hole 21, thereby increasing the number of soft bristles set in the disinfection hole 21, which can further improve the effect of coating and disinfecting the surface of the lead wire 7 and the electrode 71.

[0052] The specific implementation process is as follows: When it is necessary to disinfect the lead wire 7, open the box door 11 and first confirm whether there is enough disinfectant in the disinfectant storage tank 6. Then lift the clamping block 5 upwards to snap the USB connector 72 into the first slot 43. Next, remove the moving plate 202 and place the ten lead wires 7 under the splitter plate 74 into the different disinfection holes 21 on the fixed plate 201 one by one from left to right. Since the disinfection holes 21 on the fixed plate 201 occupy two-thirds of the total disinfection holes 21, the lead wires 7 can be well limited and will not move during the process of placing them in one by one. Then, seal the moving plate 202 on the fixed plate 201 and do a simple combing of the lead wires 7 to avoid serious tangling and knots. Then, place the lower ends of all the lead wires 7 in the cable tray to prevent them from scattering. Make full use of the length of the main line 73 so that the splitter plate 74 is located in the middle of the disinfection hole 21, so that each lead wire 7 can enter more of the disinfection hole 21, increasing the disinfection area of ​​the lead wires 7. After placing the lead wire 7, close the box door 11.

[0053] First, the motor 41 and the infusion pump are started. The infusion pump pumps the disinfectant from the disinfectant storage tank 6 into the inlet channel through the first outlet pipe, and then into each disinfection hole 21 through the connection hole 22. The soft bristles in the disinfection hole 21 absorb the disinfectant and transfer it to the surface of the guide wire 7. At the same time, the motor 41 drives the winding shaft 4 to rotate slowly, winding up the guide wire 7. The guide wire 7 slowly passes through the disinfection hole 21, and the soft bristles brush across the surface of the guide wire 7 to apply disinfection. During the winding process, the guide wire 7 is pulled out of the disinfection hole 21 one by one from left to right to avoid multiple guide wires 7 being pulled tight at the same time and forming a knot.

[0054] Once winding is complete, cylinder 31 is activated, and the output shaft of cylinder 31 extends, causing the disinfection nozzle 3 to move upward and unfold. As the disinfection nozzle 3 fully unfolds, the slide rod 341 touches the button switch 36, activating the liquid pump connected to the second liquid outlet pipe. The spray nozzles on the disinfection nozzle 3 spray disinfectant onto the ends of the electrodes 71 arranged between the clamping block 5 and the winding shaft 4, further disinfecting the ends of the electrodes 71 and improving the disinfection effect. After pressing the button switch 36, the output shaft of cylinder 31 is immediately retracted, causing the disinfection nozzle 3 to retract again, completing the disinfection process.

[0055] Example 2

[0056] like Figure 9 The medical automatic disinfection device shown differs from Embodiment 1 in that, to improve the ease of operation, a double-control switch 12 is installed on the inner wall of the top of the housing 1, and a start switch 13 is installed on the outside of the housing 1. The start switch 13 is connected to the motor 41 and the infusion pump. Pressing the start switch 13 will start the motor 41 and the infusion pump simultaneously. The motor 41 and the infusion pump are simultaneously connected to one wire of the double-control switch 12, and the cylinder 31 is connected to the other wire of the double-control switch 12. A relay is also provided between the cylinder 31 and the double-control switch 12, and a two-position five-way valve is connected to the cylinder 31. During the winding process, as the number of turns of the guide wire 7 on the winding shaft 4 increases, the clamping block 5 gradually moves upward. The distance between the double-control switch 12 and the top of the clamping block 5 is pre-set so that when the winding shaft 4 finishes winding the guide wire 7, the top of the clamping block 5 just touches the double-control switch 12. The double-control switch 12 then de-energizes the motor 41 and the infusion pump, stopping their operation. Simultaneously, the cylinder 31 is energized, and its output shaft extends, causing the disinfection nozzle 3 to unfold during its upward movement. This also helps to tighten the bottom of the guide wire 7 after winding. Disinfectant is sprayed onto the end of electrode 71. The disinfectant enters from the bottom of motor 41 and thoroughly disinfects electrode 71, improving the disinfection effect. Then, under the action of the relay's energization delay disconnection, cylinder 31 is de-energized again. At this time, under the action of the two-position five-way valve, the output shaft of cylinder 31 is retracted again, driving the disinfection nozzle 3 to move downwards while retracting, so as not to affect the use of the disinfection device next time. This process is completed by the cooperation of various components in the device without manual intervention, which greatly improves the automation and ease of use of the disinfection device.

[0057] The specific implementation process is as follows: After placing the disinfected lead wire 7 into the device, press the start switch 13, and the motor 41 and infusion pump will start working. The infusion pump pumps the disinfectant from the disinfectant storage tank 6 into the inlet channel through the first outlet pipe, and then into each disinfection hole 21 through the connection hole 22. The soft bristles in the disinfection hole 21 absorb the disinfectant and transfer it to the surface of the lead wire 7. At the same time, the motor 41 drives the winding shaft 4 to rotate slowly, winding the lead wire 7. The lead wire 7 slowly passes through the disinfection hole 21, and the soft bristles brush across the surface of the lead wire 7 for disinfection. During the winding process, the lead wire 7 will be pulled out from the disinfection hole 21 one by one from left to right to avoid multiple lead wires 7 being pulled tight at the same time during the winding process, which would cause a knot.

[0058] As the lead wire 7 is gradually wound onto the take-up shaft 4, the clamping block 5 gradually rises until the winding is complete and the clamping block 5 contacts the double-control switch 12. The double-control switch 12 controls the motor 41 and the infusion pump to stop working. At the same time, the cylinder 31 starts immediately. The output shaft of the cylinder 31 extends and drives the disinfection nozzle 3 to move upward and unfold. The slide rod 341 contacts the push button switch 36. The spray holes on the disinfection nozzle 3 spray disinfectant onto the ends of the electrodes 71 arranged between the clamping block 5 and the take-up shaft 4, disinfecting the ends of the electrodes 71 again and improving the disinfection effect. Finally, under the action of the relay energizing delay disconnection, the cylinder 31 is de-energized. After the cylinder 31 is de-energized, under the action of the two-position five-way valve, the output shaft of the cylinder 31 retracts, thereby causing the disinfection nozzle 3 to retract again, and the disinfection is completed.
