Description

Technical Field

[0001] This invention belongs to the field of medical dressing technology, specifically a sterilization and disinfection device for a medical dressing production line. Background Technology

[0002] Medical dressings are a class of medical materials used to cover sores, wounds, or other lesions. They mainly include natural gauze, synthetic fiber dressings, polymer film dressings, foamed polymer dressings, hydrocolloid dressings, and alginate dressings. Because medical dressings come into direct contact with the patient's wound, they must be disinfected and sterilized during application to ensure their safety and sterility. Currently, common methods for disinfecting and sterilizing medical dressings include high-temperature steam sterilization, ultraviolet negative ion sterilization, and disinfectant sterilization. Among these, high-pressure steam sterilization can kill not only common bacteria but also bacterial spores. It is widely used due to its advantages of fast sterilization speed, absence of any chemicals, and good sterilization effect.

[0003] Currently, some small-scale high-temperature steam sterilization devices spray high-temperature steam from specific locations or angles. This may result in insufficient sterilization of the surface of medical dressings, failing to ensure that all medical dressings receive high-pressure steam sterilization. Furthermore, medical dressings sterilized by high-pressure steam still need to be dried, and the drying process needs to be transferred to the next stage. Therefore, these devices lack the function of drying dressings, which cannot improve production efficiency. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a sterilization and disinfection device for a medical dressing production line.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sterilization and disinfection device for a medical dressing production line, comprising a conveyor, wherein multiple sets of medical dressing bodies are attached to the top surface of the conveyor, and a trough box is fixedly connected to the outer wall of the top of the conveyor. Material troughs are provided through both ends of the bottom of the trough box. The conveyor is provided with a sterilization and disinfection section, which includes a U-shaped frame plate fixedly connected to the outer wall of the top of the trough box. A motor is fixedly connected to the top of the U-shaped frame plate, and a rotating rod is fixedly connected to the shaft of the motor. The rod body and the U-shaped frame plate are rotatably connected through the rotating rod, and a sleeve rod is fixedly connected to the rod body. Rubber abutments are fixedly connected to both sides of the sleeve rod, and an elastic telescopic structure is provided below each of the two rubber abutments. A rotating spraying structure is also provided on the top side wall of the trough box, and the two elastic telescopic structures are combined to form a drying structure.

[0006] Preferably, each of the two elastic telescopic structures includes a corrugated pipe fixedly connected to the top side wall of the trough box. A ring plate is fixedly connected to the outer wall of the corrugated pipe near the top. Elastic telescopic rods are fixedly connected to the outer walls on both sides of the bottom end of the ring plate, and the bottom ends of the two elastic telescopic rods are fixedly connected to the top side wall of the trough box.

[0007] Preferably, a delivery pipe and a extraction pipe are respectively fixedly connected to the two ends of the corrugated pipe near the bottom. The pipe body of the extraction pipe is fixedly connected to the side wall of the U-shaped frame plate. A high-temperature liquid tank is fixedly connected to the other end of the pipe body. The outer wall of one end of the high-temperature liquid tank is fixedly connected to the side wall of one end of the U-shaped frame plate.

[0008] Preferably, the rotary spraying structure includes a conical plate movably sleeved in the side wall of the trough box. Multiple discharge holes are circumferentially opened on the bottom side wall of the conical plate. A sleeve plate is movably sleeved on the outer wall of the conical plate near the bottom. The sleeve plate and the rod near the bottom of the rotating rod are fixedly connected. Multiple atomizing nozzles are circumferentially and fixedly connected to the bottom end of the sleeve plate.

[0009] Preferably, two rectangular grooves are formed through the bottom two side plates of the sleeve plate, and rectangular groove plates are attached to the top outer walls of the two sets of rectangular grooves. Multiple sets of ultraviolet lamps are fixedly connected to the inner walls of the two sets of rectangular groove plates.

[0010] Preferably, two slots are provided on the inner walls of both sides of the bottom end of the sleeve plate, which can be slidably connected to the two rectangular slot plates respectively. Two springs are fixedly connected to the inner walls of both sides of the two sets of rectangular slot plates, and the bottom end of each spring is fixedly connected to the inner wall of the bottom end of the sleeve plate.

[0011] Preferably, each set of rectangular grooves has two support rods fixedly connected to its inner wall, and each set of support rods has a baffle movably sleeved on it. The outer walls at both ends of each set of baffles are respectively fixedly connected to the inner walls at both ends of each corresponding rectangular groove with torsion springs. Each set of ultraviolet lamps can intermittently slide and fit against the top outer wall of each set of baffles.

[0012] Preferably, the drying structure includes a mesh plate fixedly connected to the outer wall of the other side of the top of the trough box, and a sealing plate is tightly snapped onto the outer wall of one end of the mesh plate.

[0013] Preferably, a dividing tube is fixedly connected through a section of the conveying pipe, and the other end of the dividing tube is fixedly connected through to the outer wall of the end of the mesh plate near the bottom.

[0014] Preferably, a wind turbine is movably sleeved in the inner wall of both ends of the mesh plate, and a flow guide plate is fixedly connected to the outer wall of the bottom end of the mesh plate. The plate body of the flow guide plate and the plate body on the other side of the top of the trough box are fixedly connected through each other.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention activates a motor on a U-shaped frame plate, causing it to drive a rotating rod, sleeve rod, and rubber abutment to rotate synchronously. The rotating rubber abutment repeatedly contacts and presses against the corrugated pipe below. When the corrugated pipe passively expands and contracts, creating a negative pressure reciprocating motion, high-temperature steam is forced through multiple discharge holes and moves into the sleeve plate with impact force. Even then, the steam is still driven by the pressure generated by the corrugated pipe and sprayed out from multiple atomizing nozzles, forming an extremely fine high-temperature steam spray. When the high-temperature steam reaches the sleeve plate under pressure, it forces a rectangular groove plate to slide downwards within the groove. Thus, during the downward movement of the rectangular groove plate... The process will cause multiple sets of ultraviolet lamps to contact the corresponding baffles, causing them to rotate around the support rod as the axis. While the baffles are passively rotated, they will also drive the torsion springs to rotate and deform. The maximum rotation angle of the baffles is 90 degrees. Without the obstruction of the baffles, the ultraviolet lamps can disinfect and sterilize the medical dressings conveyed on the conveyor with ultraviolet light. Combined with the high-temperature steam sprayed by multiple atomizing nozzles, a secondary disinfection and sterilization effect is produced. During the passive rotation of the rotating rod, the sleeve plate will also rotate at a fixed point on the conical plate. The centrifugal force generated by the rotation can make the spraying range of the atomizing nozzles larger.

[0017] When high-temperature steam is introduced into the conveyor pipe, a small amount of high-temperature steam automatically enters the dividing pipe and then drifts into the mesh plate containing desiccant. At the same time, the high-temperature steam entering the mesh plate drives the impeller to rotate. During the rotation, the impeller agitates the desiccant, allowing it to completely absorb the moisture in the high-temperature steam. Thus, the remaining high-temperature gas automatically drifts down through the guide plate, thereby drying the medical dressing body that has passed through the high-temperature steam on the conveyor.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] like Figures 1 to 8As shown, the present invention provides a sterilization and disinfection device for a medical dressing production line, including a conveyor 1. Multiple sets of medical dressing bodies 11 are attached to the top surface of the conveyor 1. A trough box 12 is also fixedly connected to the outer wall of the top of the conveyor 1. A material trough 13 is opened through both ends of the bottom of the trough box 12. The conveyor 1 is provided with a sterilization and disinfection section 2. The sterilization and disinfection section 2 includes a U-shaped frame plate 21 fixedly connected to the outer wall of the top of the trough box 12. A motor 22 is fixedly connected to the top of the U-shaped frame plate 21. A rotating rod 23 is fixedly connected to the shaft of the motor 22. The rod body of the rotating rod 23 is rotatably connected to the U-shaped frame plate 21. A sleeve rod 24 is also fixedly connected to the rod body of the rotating rod 23. Rubber abutment plates 25 are fixedly connected to both sides of the sleeve rod 24. An elastic telescopic structure is provided below the two rubber abutment plates 25. A rotating spraying structure is also provided on the top side wall of the trough box 12. The two elastic telescopic structures are combined to form a drying structure.

[0031] The above solution is adopted: by starting the conveyor 1 in the existing technology, the medical dressing body 11 is moved. The continuous movement will passively pass through the material trough 13 opened on one end of the trough box 12 and enter the trough box 12. At the same time, the motor 22 on the U-shaped frame plate 21 is started, which drives the rotating rod 23 and the sleeve rod 24 to rotate synchronously, thereby driving the rubber abutment plates 25 on both sides of the sleeve rod 24 to rotate synchronously.

[0032] Each of the two elastic telescopic structures includes a corrugated pipe 26 fixedly connected to the top side wall of the trough box 12. A ring plate 27 is fixedly connected to the outer wall of the corrugated pipe 26 near the top. Elastic telescopic rods 28 are fixedly connected to the outer walls of the bottom two sides of the ring plate 27. The bottom ends of the two elastic telescopic rods 28 are fixedly connected to the top side wall of the trough box 12. A delivery pipe 29 and a extraction pipe 230 are respectively fixedly connected to the two ends of the corrugated pipe 26 near the bottom. The pipe body of the extraction pipe 230 is fixedly connected to the side wall of the U-shaped frame plate 21. A high-temperature liquid tank 231 is fixedly connected to the other end of the pipe body of the extraction pipe 230. One end of the outer wall of the high-temperature liquid tank 231 is fixedly connected to one end of the side wall of the U-shaped frame plate 21.

[0033] Using the above scheme: the rubber abutment 25 rotates to repeatedly contact and press the corrugated pipe 26 below. When the corrugated pipe 26 passively generates a reciprocating motion of expansion and contraction, the negative pressure generated inside can draw the water heated at high temperature in the high-temperature liquid tank 231 through the suction pipe 230, and draw the high-temperature steam generated in the water. Then, the high-temperature steam is drawn from the conveying pipe 29 through the corrugated pipe 26 under pressure and introduced into the conical plate 233 that is fixedly connected to the conveying pipe 29.

[0034] The rotary spraying structure includes a conical plate 233 movably fitted into the side wall of the trough box 12. Multiple discharge holes 234 are arranged around the bottom side wall of the conical plate 233. A sleeve plate 235 is movably fitted onto the outer wall of the conical plate 233 near the bottom. The sleeve plate 235 and the rod near the bottom of the rotating rod 23 are fixedly connected. Multiple atomizing nozzles 236 are fixedly connected around the bottom end of the sleeve plate 235. Two rectangular grooves are opened through the bottom two side plates of the sleeve plate 235. Rectangular groove plates 237 are attached to the top outer walls of the two sets of rectangular grooves. Multiple sets of ultraviolet lamps 238 are fixedly connected to the inner walls of the two sets of rectangular groove plates 237. The sleeve plate 235... Two slots 239 are provided on the inner walls of both sides of the bottom end, which can be slidably connected to the two rectangular slot plates 237 respectively. Two springs 240 are fixedly connected to the inner walls of both sides of the two sets of rectangular slot plates 237. The bottom end of each spring 240 is fixedly connected to the inner wall of the bottom end of the sleeve plate 235. Two support rods 241 are fixedly connected to the inner wall of each set of rectangular slots. A baffle 242 is movably sleeved on each set of support rods 241. The outer walls of both ends of each set of baffles 242 are respectively fixedly connected to the inner walls of both ends of each corresponding rectangular slot with torsion springs 243. Each set of ultraviolet lamps 238 can be intermittently slidably connected to the outer wall of the top end of each set of baffles 242.

[0035] Using the above scheme: High-temperature steam will be squeezed and impacted as it moves down through multiple feed holes 234 into the sleeve 235. Even so, it will still be driven by the squeezing impact force generated when the bellows 26 is pressed out from multiple atomizing nozzles 236, forming an extremely fine high-temperature steam spray. When the high-temperature steam reaches the sleeve 235 under pressure, it will squeeze the rectangular slot plate 237 to slide down within the slot 239. As the rectangular slot plate 237 moves down, it will cause multiple sets of ultraviolet lamps 238 to contact the corresponding baffles 242, causing them to rotate around the support rod 241 as the axis. While the passive rotation of 42 is occurring, it also drives the torsion spring 243 to rotate and deform. The maximum rotation angle of the baffle 242 is 90 degrees. Without the obstruction of the baffle 242, the ultraviolet lamp 238 can disinfect and sterilize the medical dressing body 11 conveyed on the conveyor 1 with ultraviolet light. Combined with the high-temperature steam sprayed by multiple atomizing nozzles 236, a secondary disinfection and sterilization effect is produced. During the passive rotation of the rotating rod 23, it also drives the sleeve plate 235 to rotate at a fixed point on the conical plate 233. The centrifugal force generated by the rotation can make the spraying range of the atomizing nozzles 236 larger.

[0036] The drying structure includes a mesh plate 244 fixedly connected to the outer wall of the top of the trough box 12. A sealing plate is tightly snapped onto the outer wall of one end of the mesh plate 244. A dividing pipe 2441 is fixedly connected through a section of the conveying pipe 29. The other end of the dividing pipe 2441 is fixedly connected through the outer wall of the mesh plate 244 near the bottom. A fan wheel 245 is movably sleeved in the inner wall of both ends of the mesh plate 244. A guide plate 246 is fixedly connected to the outer wall of the bottom end of the mesh plate 244. The plate body of the guide plate 246 is fixedly connected through the plate body of the top of the trough box 12.

[0037] The above scheme is adopted: when high-temperature steam is introduced into the conveying pipe 29, a small amount of high-temperature steam will automatically enter the dividing pipe 2441 and drift into the mesh plate 244 containing desiccant. At the same time, the high-temperature steam entering the mesh plate 244 will drive the impeller 245 to rotate. During the rotation, the impeller 245 will agitate the desiccant, so that it can completely absorb the moisture in the high-temperature steam. Thus, the remaining high-temperature gas will automatically drift down through the guide plate 246, thereby drying the medical dressing body 11 on the conveyor 1 after passing through the high-temperature steam.

[0038] The working principle and usage process of this invention are as follows: The conveyor 1 in the prior art is started, causing it to move the medical dressing body 11. This continuous movement passively passes through the material trough 13 at one end of the trough box 12, entering the trough box 12. Simultaneously, the motor 22 on the U-shaped frame 21 is started, causing the rotating rod 23 and the sleeve rod 24 to rotate synchronously. This causes the rubber abutments 25 on both sides of the sleeve rod 24 to rotate synchronously, repeatedly contacting and pressing against the corrugated pipe 26 below. When the corrugated pipe 26 passively undergoes a reciprocating motion of expansion and contraction, it can... The internal negative pressure draws high-temperature steam from the heated water in the high-temperature tank 231 through the suction pipe 230. The steam is then drawn from the water and pressurized through the corrugated pipe 26, and introduced into the conical plate 233, which is connected to and permeates the pipe 29. The steam is then compressed and impact-driven, flowing down through multiple discharge holes 234 into the sleeve 235. Even then, the pressure generated by the corrugated pipe 26 propels the steam out through multiple atomizing nozzles 236, creating extremely fine high-temperature... When steam is sprayed and reaches the sleeve 235 under the pressure of high-temperature steam, it will compress the rectangular slot plate 237 and make it slide downward within the slot 239, thereby compressing multiple corresponding springs 240. The springs 240 can be used to drive the rectangular slot plate 237 to automatically reset. As the rectangular slot plate 237 moves downward, it will cause multiple sets of ultraviolet lamps 238 to contact the corresponding baffles 242, causing them to rotate around the support rod 241. The passive rotation of the baffles 242 will also drive the torsion springs 243 to rotate and deform, and the rotation angle of the baffles 242 will also be affected. The maximum angle is 90 degrees, and without the obstruction of the baffle 242, the ultraviolet lamp 238 can disinfect and sterilize the medical dressing body 11 conveyed on the conveyor 1 with ultraviolet light. Combined with the high-temperature steam sprayed by multiple atomizing nozzles 236, a secondary disinfection and sterilization effect is produced. In addition, during the passive rotation of the rotating rod 23, the sleeve 235 will also be driven to rotate at a fixed point on the conical plate 233. The centrifugal force generated by the rotation can make the spraying range of the atomizing nozzles 236 larger, avoiding the specific area spraying disinfection method, and making its high-temperature sterilization method more comprehensive.

[0039] Furthermore, when high-temperature steam is introduced into the conveying pipe 29, a small amount of high-temperature steam will automatically enter the dividing pipe 2441 and drift into the mesh plate 244 containing desiccant. At the same time, the high-temperature steam entering the mesh plate 244 will drive the impeller 245 to rotate. During the rotation, the impeller 245 will agitate the desiccant, enabling it to completely absorb the moisture in the high-temperature steam. Thus, the remaining high-temperature gas will automatically drift down through the guide plate 246, thereby drying the medical dressing body 11 on the conveyor 1 after it has been exposed to high-temperature steam. This avoids the need for the medical dressing body 11 to be transferred again for drying in the prior art.
