Traditional medical device cleaning methods mainly rely on manual operations. Although this method can achieve a certain cleaning effect, there are many problems, such as low cleaning efficiency, high labor intensity, incomplete cleaning, and secondary contamination that may be caused by improper manual cleaning.

The free end of the traction line 208 is fixedly connected to the upper end of the limiting plate 219. When a larger instrument (such as a metal plate) is placed on the support plate 204, the protruding side of the metal plate will contact the pressure rod 203. Then, when the pressure rod 203 moves downward, the traction line 208 is pulled downward by the limiting plate 219, so that the two clamping blocks move in opposite directions, thereby tightening and fixing the metal plate;

[0046] like Figure 5 , Figure 7 As shown, more specifically, a rectangular through hole is provided on the outer surface of the support plate 204, and a clamping block 210 is inserted into the inner surface of the rectangular through hole. A high-temperature resistant non-slip rubber block is fixedly connected to the end of the clamping block 210 away from the support plate 204, and a driving screw 213 is rotatably installed on the inner end of the clamping block 210.

The expansion piece 216 is made of elastic metal material, and the outer surface is wrapped with a high-temperature resistant rubber non-slip pad sleeve, and the outer surface of the driving screw 213 is threadedly sleeved with a movable sleeve 215, and the expansion piece The right end of 216 is fixedly connected to the movable sleeve 215. When the driving screw 213 rotates, the movable sleeve 215 moves to the left. At this time, the expansion piece 216 is deformed by the extrusion force and deforms in the direction away from the driving screw 213, and then contacts the inside of the support plate 204. The right end of the clamping block 210 is rotatably installed with a rotating piece 214 for easy force application. The driving screw 213 is fixedly connected to the rotating piece 214, so that after the instrument is placed on the top of the tray 202, the clamping block 210 can be quickly moved and then clamped and fixed.

[0047] like Figure 4 - Figure 6 , Figure 8As shown, movable rods 206 are penetrated at both ends of the left and right sides of the tray 202, and driving racks 212 are slidably installed at both ends of the inner side of the tray 202, and the movable rod 206 is fixedly connected to the driving rack 212. A plurality of lifting plates 218 are rotatably installed at the inner upper end of the tray 202, and the lifting plates 218 correspond to the support plate 204 and are located below the support plate 204. A driving rod 209 is rotatably installed at the inner end of the tray 202, and the lifting plates 218 are fixedly connected to the driving rod 209. The right end of the driving rod 209 is fixedly connected to a passive gear 211, and the passive gear 211 meshes with the driving rack 212. A switching block 207 is sleeved on the outer surface of the movable rod 206. Specifically, two limit blocks are fixedly installed on the outer surface of the movable rod 206, and the switching block 207 is located between the two limit blocks, and the switching block 207 can move freely in the space restricted by the two limit blocks. A locking groove 217 is opened on the outer surface of the tray 202, and the locking groove 217 corresponds to the switching block 207, and the size of the locking groove 217 is equal to that of the switching block 207. When the switching block 207 is rotated and embedded in the locking groove 217, the switching block 207 cannot move, so that the movable rod 206 cannot move with the switching block 207.

[0048] See also Figure 2 , Figure 8 - Fig.10 A card plate 405 is slidably mounted on the upper end of the movable plate 401, and the card plate 405 corresponds to the switching block 207. A bayonet is provided at the left end of the card plate 405, and the bayonet width is equal to the length of the switching block 207. An electric push rod 404 is fixedly mounted on the right end of the isolation frame 101, and the telescopic end of the electric push rod 404 is fixedly connected to the bottom end of the movable plate 401. A driving motor 403 is fixedly mounted on the upper end of the movable plate 401, and a lifting screw 409 is fixedly connected to the output end of the driving motor 403.

When the bayonet at the left end of the card plate 405 clamps the switching block 207, if the switching block 207 can move normally, the output end of the driving motor 403 drives the lifting screw 409 to rotate, and then the lifting screw 409 can directly drive the passive sleeve 402 to rotate, and under the action of the abutment block 408 being clamped between the two blocks 407, the card plate 405 starts to move. If the switching block 207 cannot move, the card plate 405 cannot move normally. At this time, when the lifting screw 409 rotates, the abutment block 408, under the limiting action of the two blocks 407, causes the movable sleeve 215 to move upward.

[0050] Example 3: Please refer to Figure 2 , Fig. 9 , Fig.11 , Fig.12 , Fig.13 , a medical device scrubbing device, combined with Example 1 and Example 2, the spray device includes a heating tube 303, the heating tube 303 is fixedly installed at the inner end of the extension sleeve 301, and a heating wire is arranged inside the heating tube 303.

The infusion tube 302 is a combination of two pipes of different materials, namely a high-temperature resistant silicone rubber tube (-60°C to 250°C) and a metal steel pipe. The metal steel pipe part is penetrated into the interior of the heating tube 303, and the outer surface is tightly fitted with the inner wall of the heating tube 303, and is sealed by a silicone rubber sealing ring to increase the sealing performance. The extension sleeve 301 located above the support frame 201 is fixedly connected to the isolation frame 101 , the heating tube 303 inside the extension sleeve 301 located above the support frame 201 is directly fixedly connected to the metal steel pipe part of the infusion tube 302, the extension sleeves 301 on the left and right sides of the isolation frame 101 are slidably installed on the upper end of the passive sleeve 402, and the left and right ends of the isolation frame 101 are provided with limiting grooves 406, the left end of the extension sleeve 301 is arranged inside the limiting groove 406, and the upper and lower sides of the limiting groove 406 are provided with through holes of the same size as the extension sleeve 301, so that the extension sleeve 301 can be more accurately inserted into the through hole within the limited space. Specifically, the length of the lifting screw 409 is equal to the width of the limiting groove 406, and the extension sleeves 301 on the left and right sides of the isolation frame 101 are connected to the movable plate 401 through a tension spring, and the pressure of the water flow inside the infusion tube 302 is greater than the elastic force of the tension spring;

[0051] A plurality of output sleeves 306 are fixedly welded at both upper and lower ends of the inner side of the extension sleeve 301. A plurality of shunt pipes 304 are fixedly connected to the outer surface of the heating tube 303. The end of the shunt pipe 304 away from the heating tube 303 is fixedly connected to the output sleeve 306. A passive ring 312 is provided at the inner end of the output sleeve 306. The passive ring 312 and the shunt pipe 304 are connected by a telescopic pipe 313. The passive ring 312, the shunt pipe 304 and the telescopic pipe 313 are all made of metal. The telescopic part of the telescopic pipe 313 is sealed by a silicone rubber sealing ring, which can withstand high temperatures and ensure sealing. A heat receiving pipe 305 is fixedly installed at the inner end of the extension sleeve 301. The heat receiving pipe 305 is made of metal. The inner end of the heat receiving pipe 305 is fixedly A bimetallic spiral sheet 308 is fixedly installed. The bimetallic spiral sheet 308 is formed by overlapping two metals with different thermal expansion coefficients. In the process of temperature change, due to the difference in thermal expansion coefficients, distortion occurs. A switching rod 307 is penetrated at the inner end of the heat receiving tube 305. The right end of the bimetallic spiral sheet 308 is fixedly connected to the outer surface of the switching rod 307, and the left and right ends of the switching rod 307 are respectively penetrated inside two adjacent output sleeves 306. The end of the switching rod 307 away from the heat receiving tube 305 is fixedly connected to a cam 309 by bolts. The cam 309 is located below the passive ring 312. Then, when the cam 309 rotates, the outer surface of the cam 309 contacts the bottom end of the passive ring 312 and then moves upward;

[0052] like Fig.12 , Fig.13As shown, a heating ring 310 is fixedly installed at the inner bottom end of the output sleeve 306, and a support tube 311 is fixedly installed at the upper end of the heating ring 310. The support tube 311 is made of metal, and a passive ring 312 is sleeved on the outer surface of the support tube 311. The outer surface of the support tube 311 is sleeved with a silicone rubber sealing ring and is in close contact with the inner wall of the passive ring 312. A connecting rod 314 is fixedly installed at the inner end of the passive ring 312, and the bottom end of the connecting rod 314 is fixedly connected to an injection pipe 316. A flow groove is opened on the outer surface of the connecting rod 314 and corresponds to the injection pipe 316. A nozzle 317 is fixedly installed at the inner bottom end of the support tube 311. The nozzle 317 is made of a high-resistance metal material (such as stainless steel), and the nozzle 317 is funnel-shaped. A liquid outlet 318 is fixedly installed at the upper end of the nozzle 317, and a switching plug 315 is fixedly installed on the outer surface of the injection pipe 316. When the switching plug 315 moves downward, the liquid outlet 318 is blocked. At the same time, the bottom end of the injection pipe 316 contacts the center of the nozzle 317 (i.e., the smallest part of the center of the funnel). Specifically, an electromagnetic coil is installed inside the heating ring 310. When an alternating current passes through the coil, an alternating magnetic field is generated around it. At the same time, the nozzle 317 is located inside the alternating magnetic field. The alternating magnetic field will induce eddy currents inside the metal. When the eddy current flows in the nozzle 317, heat (Joule effect) is generated due to the resistance of the nozzle 317, thereby quickly heating the nozzle 317, thereby heating the water flowing inside.

[0053] More specifically, a temperature sensor is provided inside the extension sleeve 301. The specific working principle of the temperature sensor is an existing mature technology and will not be elaborated here. When the internal temperature of the extension sleeve 301 reaches a certain threshold, the control terminal on the outer surface of the equipment box 1 begins to make decisions, driving the vacuum press 103 to start extracting the air inside the pressure box 105 until a vacuum state is formed. At the same time, air is continuously applied to the inside of the water collecting box 102 through its natural air intake port (Note: the vacuum press 103 has a natural air intake port) to ensure that the water inside can still be sprayed out normally.

[0054] See also Fig.14 , Fig.15 A sliding base frame 108 is slidably mounted on the upper end of the isolation frame 101, an extraction tube 107 is fixedly connected to the upper end of the pressure box 105, a driving gear 111 is rotatably mounted on the upper end of the extraction tube 107, a passive rack is fixedly mounted on one end of the sliding base frame 108 close to the driving gear 111, and the passive rack is meshed with the driving gear 111, so when the sliding base frame 108 slides, the driving gear 111 is driven to rotate through the passive rack;

[0055] A connecting pipe 113 is provided inside the extraction pipe 107. When the connecting pipe 113 moves upward, the ventilation can flow into the interior of the pressure box 105 through the connecting pipe 113. Specifically, a rectangular block is fixedly installed on the outer surface of the connecting pipe 113. A rectangular groove is provided at the inner end of the extraction pipe 107. The rectangular block is located in the rectangular groove, so that the connecting pipe 113 is prevented from rotating during the upward movement. A passive screw 112 is fixedly welded to the upper end of the connecting pipe 113, and a driving gear 111 is threadedly sleeved on the outer surface of the passive screw 112. A plurality of ventilation holes are provided on the outer surface of the driving gear 111 to ensure the normal flow of air.

[0056] A plurality of triangular blocks 110 are fixedly installed on the upper end of the sliding base 108. The triangular blocks 110 are of different sizes. The bottom end of the support frame 201 is supported by a plurality of cross bars. The triangular blocks 110 are inserted between two cross bars. Only two cross bars with a specific spacing allow the triangular blocks 110 to pass through smoothly, thereby preventing the support frame 201 from being stuck by the triangular blocks 110 when it has not fully moved to the specified position during the sliding process. The sliding base 108 and the isolation frame 101 are connected by a reset spring 109. When the support frame 201 moves, the sliding base 108 is driven to move by the triangular blocks 110. Then, after the support frame 201 continues to move, the cross bar is slightly lifted upward under the action of the contact between the slope surface of the triangular block 110, and finally disconnected from the triangular block 110.

[0057] The working principle of the present invention is:

[0058] When in use, the medical device to be sterilized is placed on the support plate 204, and then the support frame 201 is placed on the feed table 2, and enters the interior of the isolation frame 101 through the rolling of the pulley 3. The telescopic end of the electric push rod 404 drives the movable plate 401 to move, and the bayonet at the left end of the card plate 405 clamps the switching block 207. If the device placed on the support plate 204 is a plate, the staff has already embedded the switching block 207 in the movable rod 206. At this time, the switching block 207 cannot move, and the card plate 405 cannot move normally. At this time, when the lifting screw 409 rotates, the abutment block 408 is restricted by the two card blocks 407, so that the movable sleeve 215 moves upward. The movement avoids the extension sleeve 301 from damaging the instrument when it moves. If it is a long strip instrument, the switching block 207 can move normally, and the output end of the driving motor 403 drives the lifting screw 409 to rotate, and then the lifting screw 409 can directly drive the passive sleeve 402 to rotate, and the abutment block 408 is clamped between the two clamping blocks 407, so that the clamping plate 405 starts to move, and drives the passive gear 211 to rotate by driving the rack 212, and then the passive gear 211 drives the driving rod 209 to rotate, and the driving rod 209 rotates to drive the lifting plate 218 to rotate, and lift the support plate 204 to rotate it to a certain angle. At this time, the end of the instrument away from the support plate 204 is tilted;

[0059] Then, the vacuum press 103 applies pressure to the inside of the water collecting box 102, so that the pressure inside the water collecting box 102 increases, and the water flow inside enters the inside of the heating tube 303 along the infusion tube 302, and the extension sleeves 301 on the left and right sides of the isolation frame 101 start to move under the pressure of the water flow, and then move to the bottom of the device, at which time the temperature of the heating tube 303 gradually increases;

[0060] The water flows through the shunt pipe 304 to the inside of the injection pipe 316, and starts to sputter and clean the outer surface of the instrument. At this time, the heating ring 310 also starts to heat the nozzle 317. As the temperature gradually rises, the water flowing to the nozzle 317 begins to boil and vaporize directly. At the same time, as the temperature of the heating tube 303 rises, the bimetallic spiral sheet 308 is twisted by heat when the metal has the property of heat transfer, and drives the switching rod 307 to rotate. At this time, the cam 309 drives the passive ring 312 to move upward, and the passive ring 312 During the upward movement, the injection tube 316 is driven to move upward through the connecting rod 314, and the switching plug 315 no longer blocks the liquid outlet 318. At this time, when the heated water flows to the nozzle 317, the contact area with the nozzle 317 becomes larger. Since the hole of the nozzle 317 is small, the water flow has a sufficiently long contact time and is directly vaporized under the action of high temperature and sprayed on the outer surface of the instrument, quickly drying the residual water on the outer surface of the instrument, and driving the vacuum press 103 to start extracting the air inside the pressure box 105 until a vacuum state is formed.

[0061] Subsequently, after the equipment is cleaned and dried, the control terminal controls all devices to return to their initial state. The movable plate 401 returns to its initial state under the action of the electric push rod, and the extension sleeve 301 returns to its initial state under the action of the tension spring. The telescopic end of the electric push rod 404 pushes the support frame 201 to move. During the movement of the support frame 201, the pressure box 105 absorbs the redundant heat inside the isolation frame 101 through the extraction tube 107, thereby avoiding hot air from gushing out when the insulating tempered glass is opened, thereby increasing a certain degree of safety.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed in the present invention, which should be covered by the protection scope of the present invention.
