Description

Technical Field

[0001] This invention belongs to the field of gauze disinfection technology, specifically an automatic gauze disinfection machine. Background Technology

[0002] Gauze is widely used in various departments of hospitals as a medical consumable, especially surgical gauze. For departments with high requirements for the cleanliness of gauze, such as burn surgery, oncology surgery, and ophthalmology, non-sterile gauze can no longer meet the requirements of patients. Furthermore, sterile gauze will lose its sterility if it is exposed to a bacterial environment for a long time after being opened. Therefore, it is necessary to disinfect the gauze.

[0003] A Chinese patent with publication number CN109200302A discloses a gauze disinfection device, including a sealed box. Multiple ultraviolet lamps are installed on the top and bottom surfaces of the box. The box contains multiple horizontal first rollers that can move upwards and return to their original position downwards. These first rollers are arranged side-by-side with a gap between them. A second roller that can move downwards and return to its original position is located between every two adjacent first rollers. Initially, the first rollers are positioned below the second rollers, with a horizontal gap between the lower first rollers and the upper second rollers. By fully unfolding the gauze and exposing it to the ultraviolet lamps on both sides during the gauze roll disinfection process, disinfection is faster and more thorough, effectively improving the efficiency of gauze disinfection.

[0004] In current technologies, due to the limited lifespan and easy decay of ultraviolet lamps, the disinfection effect may not be very good in the later stages. Moreover, when the thickness of the gauze changes or when it is stacked and overlapped, the ultraviolet penetration rate is significantly reduced, and the disinfection effect is not very good either.

Detailed Implementation

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 4As shown in the embodiment of the present invention, an automatic gauze sterilizer includes a pretreatment box 1; a first sterilization box 2, a second sterilization box 3, and a winding box 4 are sequentially arranged on one side of the pretreatment box 1; a winding shaft 11 is rotatably connected to the inner wall of the pretreatment box 1 via bearings; a toggle mechanism is provided inside the first sterilization box 2; the toggle mechanism includes two toggle rods 21, one end of each toggle rod 21 is fixedly connected to a connecting shaft 23, and the other end of each connecting shaft 23 is fixedly connected to a second rotating wheel 24. A second belt 25 is sleeved between them; a pretreatment mechanism is also provided inside the pretreatment box 1; the pretreatment mechanism includes three cleaning rollers 18 rotatably connected to the inner wall of the pretreatment box 1 by bearings, and the three cleaning rollers 18 are arranged in a triangle; a third rotating wheel 26 is fixedly connected to one end of the connecting shaft 23 near the cleaning roller 18, and a rotating wheel is fixedly connected to one end of the cleaning roller 18 near the actuating rod 21, and a third belt 27 is sleeved between the rotating wheel and the third rotating wheel 26; a driving mechanism is provided at one end of the cleaning roller 18.

[0024] In existing technologies, due to the limited lifespan and easy decay of ultraviolet lamps, the disinfection effect may not be very good in the later stages. Moreover, when the thickness of the gauze changes or when it is stacked and overlapped, the ultraviolet penetration rate is significantly reduced, and the disinfection effect is not very good either.

[0025] In use, the actuating mechanism provided by this invention first drives the unwinding shaft 11 to rotate, which in turn drives the cleaning roller 18 to rotate. The cleaning roller 18 then drives the connected wheel to rotate, which in turn drives the third belt 27 to rotate. The third belt 27 then drives the third wheel 26 to rotate, which in turn drives the connected shaft 23 to rotate. The connected shaft 23 then drives the second wheel 24 to rotate, which in turn drives another second wheel 24 via the second belt 25. This, in turn, drives another connected shaft. The rotating shaft 23 drives the rotating rod 22 to rotate, which in turn drives the actuating rod 21 to rotate around the connecting shaft 23. The actuating rod 21 rotates up and down to beat the gauze, which helps the gauze to fully contact the disinfectant for disinfection. The periodic actuation causes the gauze fibers to repeatedly stretch and contract, forcing the disinfectant to penetrate deep into the fabric, which is especially suitable for medical gauze with a dense weave. Moreover, the actuating rod 21 breaks the static adsorption layer of disinfectant on the surface of the gauze, maintaining effective contact between fresh disinfectant and the gauze and avoiding sterilization blind spots caused by local depletion. By activating the drive mechanism, the cleaning roller 18 is driven to peel off physical impurities such as attached threads and fiber debris from multiple angles, significantly reducing the contaminants remaining in the gauze roll and solving the problem that traditional ultraviolet disinfection cannot remove physical impurities. The cleaning roller 18 can be a soft brush roller for deep cleaning of micro-dust, or a silicone polishing roller to improve the smoothness of the gauze. By integrating an infrared turbidity sensor at the shaft end of the cleaning roller 18, the cleanliness of the gauze surface is monitored in real time. When the contaminants exceed the standard, an alarm should be triggered in time to replace the cleaning roller 18.

[0026] like Figure 3 and Figure 4 As shown, the drive mechanism includes a first gear 14 and a second gear 15. One end of the unwinding shaft 11 extends to the outside of the pretreatment box 1 and is fixedly connected to the first gear 14. One end of each cleaning roller 18 extends to the outside of the pretreatment box 1 and is fixedly connected to a first rotating wheel 16. One end of a cleaning roller 18 near the unwinding shaft 11 is fixedly connected to a second gear 15. The first gear 14 meshes with the second gear 15. A first belt 17 is sleeved on the outside of the three first rotating wheels 16. A first motor 12 is fixedly connected to the outer wall of the pretreatment box 1 via an L-shaped plate 13. The output shaft of the first motor 12 is fixedly connected to one end of the unwinding shaft 11.

[0027] When the drive mechanism provided by this invention is in use, it is a gauze unwinding type. The first motor 12 needs to be turned on. The output shaft of the first motor 12 drives the unwinding shaft 11 to rotate. The unwinding shaft 11 drives the gauze to rotate and unwind. During the rotation of the unwinding shaft 11, the first gear 14 is driven to rotate. The first gear 14 drives the second gear 15 to rotate in the opposite direction. The second gear 15 drives the connected cleaning roller 18 to rotate. The cleaning roller 18 drives the first belt 17 to rotate through the connected first rotating wheel 16. The first belt 17 drives the other two first rotating wheels 16 to rotate. The first rotating wheels 16 drive the cleaning roller 18 to rotate. Thus, the cleaning roller 18 and the unwinding shaft 11 rotate in opposite directions, which facilitates the multi-angle peeling of attached physical impurities such as thread ends and fiber debris from the gauze surface.

[0028] like Figure 3 and Figure 4 As shown, a first partition 19 is provided between the pretreatment box 1 and the first disinfection box 2. A first through hole is provided on the first partition 19, and a clamping mechanism is provided in the first through hole for sealing the pretreatment box 1 and the first disinfection box 2.

[0029] When the clamping mechanism provided by the present invention is used, the first through hole of the first partition 19 is provided with a clamping mechanism to fix the position of the gauze when it transitions to the first disinfection box 2, to prevent the disinfectant in the first disinfection box 2 from splashing, and to ensure that the gauze passes through the cleaning area flat and orderly, avoiding incomplete cleaning due to wrinkles or displacement.

[0030] like Figure 2 As shown, the second disinfection box 3 is connected and fixed to the side wall of the first disinfection box 2 through the first port; a plurality of first guide rollers 31 and second guide rollers 32 are connected and fixed to the inner wall of the second disinfection box 3, and the plurality of first guide rollers 31 and second guide rollers 32 are arranged in an S-shape; a second partition 34 is fixed inside the second disinfection box 3, and a clamping mechanism is provided in the second through hole on the second partition 34.

[0031] When the first guide roller 31 and the second guide roller 32 provided by the present invention are in use, the gauze passes through the bottom of the actuating rod 21, then through the first opening into the second disinfection box 3, and then passes through the first guide roller 31 and the second guide roller 32 in an S-shape, which facilitates the drying and secondary disinfection of the gauze. The gauze is clamped by the clamping mechanism to reduce the leakage of hot air and improve the drying efficiency.

[0032] like Figure 2 and Figure 5 As shown, heating boxes 35 are installed on the top and bottom inner walls of the second disinfection box 3 near the first disinfection box 2, and two exhaust fans 36 are installed in each heating box 35; heating tubes 37 are fixedly connected to the end of the heating box 35 near the first guide roller 31; multiple ultraviolet lamps 33 are installed on the top and bottom inner walls of the second disinfection box 3 away from the first disinfection box 2.

[0033] When the heating box 35 provided by the present invention needs to be heated, the heating tube 37 and the exhaust fan 36 are powered on. The heating tube 37 emits heat, which is blown onto the gauze by the exhaust fan 36, which is beneficial to drying the gauze. Then, the gauze is irradiated with ultraviolet light by the ultraviolet lamp tube 33 to achieve the effect of secondary disinfection.

[0034] like Figure 8 As shown, the winding box 4 is connected and fixed to the side wall of the second disinfection box 3 away from the first disinfection box 2 through the second port; the top of the winding box 4 is rotatably connected to the third guide roller 41 through the bearing; two fixed plates 412 are symmetrically fixed to the side wall of the winding box 4, and a slide rod 413 is fixed between the two fixed plates 412. A slider 414 is slidably connected to the slide rod 413, and a limit roller 411 is rotatably connected between the two sliders 414. A first spring 415 is sleeved on the outside of the slide rod 413, and the limit roller 411 is horizontally aligned with the third guide roller 41.

[0035] When the third guide roller 41 and the limiting roller 411 provided by the present invention are used, the yarn is conveyed downward through the third guide roller 41 and the limiting roller 411. During the conveying process, it needs to be cut. Since the two ends of the limiting roller 411 are pushed to one side of the third guide roller 41 by the first spring 415, the yarn is clamped by the slider 414 to prevent the yarn from rebounding during the cutting process, which would be detrimental to the next winding and cutting.

[0036] like Figure 10 As shown, two third motors 437 are symmetrically fixed to the outer wall of the winding box 4. The output shafts of the third motors 437 are rotatably connected to the winding box 4 via bearings. A rotating plate 436 is fixed to the output shaft of each third motor 437. An electric push rod 435 is fixed to the side wall of each rotating plate 436. A mounting bracket 432 is fixed to the output end of each electric push rod 435. A bidirectional ball screw 433 is rotatably connected to each mounting bracket 432 via bearings. Two moving plates 431 are threadedly connected to each bidirectional ball screw 433. A clamping roller 43 is rotatably connected to each moving plate 431. A motor is provided at one end of each bidirectional ball screw 433. Two crossbars 434 are fixed to each mounting bracket 432. The moving plates 431 slide on the two crossbars 434. The clamping rollers 43 are located directly below the third guide roller 41.

[0037] The clamping roller 43 provided by this invention is used for clamping and winding. When winding is required, the mounting frame 432 and the clamping roller 43 are pushed to both sides of the yarn by the electric push rod 435. Then, the motor is turned on, and the output group of the motor drives the bidirectional ball screw 433 to rotate. The bidirectional ball screw 433 drives the moving plate 431 to move towards the yarn until the yarn is clamped. Then, the third motor 437 is turned on, and the output shaft of the third motor 437 drives the rotating plate 436, the electric push rod 435, the mounting frame 432 and the clamping roller 43 to rotate for winding. When the yarn reaches a suitable thickness, the third motor 437 is stopped for cutting. Then, the electric push rod 435 is turned on to retract. During the retraction process, the yarn falls off, completing one winding cycle.

[0038] like Figure 9 As shown, a reciprocating lead screw 42 is rotatably connected to the side wall of the winding box 4 via a bearing. A mounting plate 422 is threaded onto the reciprocating lead screw 42. Two guide rods 421 are fixedly connected to the side wall of the winding box 4, and the mounting plate 422 is slidably connected to the two guide rods 421. A cutting blade 423 is mounted on the side wall of the mounting plate 422 near the clamping roller 43. A second motor 424 is provided at one end of the reciprocating lead screw 42. A distance sensor 44 is fixedly connected to the side wall of the winding box 4 away from the cutting blade 423.

[0039] The cutting blade 423 provided by this invention is used to cut gauze. After being wound to a suitable thickness, the distance sensor 44 monitors the set value, and the system controls the third motor 437 to turn off while the second motor 424 turns on. The output shaft of the second motor 424 drives the reciprocating screw 42 to rotate, which in turn drives the mounting plate 422 to move. The mounting plate 422 then drives the cutting blade 423 to move, and the cutting blade 423 cuts the gauze to obtain the required length.

[0040] like Figure 2 As shown, a storage box 5 is fixedly connected to the bottom of the winding box 4 through a hollowed-out design, and an inclined plate 51 is fixedly connected to the inner wall of the bottom of the storage box 5.

[0041] When the storage box 5 provided by the present invention is in use, the cut gauze is retracted by opening the electric push rod 435. During the retraction process, the gauze falls into the storage box 5 and then slides to one end of the storage box 5 via the inclined plate 51 for easy removal.

[0042] like Figure 6 and Figure 7 As shown, the clamping mechanism includes a first pressure roller 6 rotatably connected to the bottom end of the first through hole, a sliding frame 62 slidably connected to the top end of the first through hole, a second pressure roller 61 rotatably connected to the bottom of the sliding frame 62, a plurality of second springs 63 fixedly connected between the sliding frame 62 and the top inner wall of the first through hole, a first electromagnetic block 64 fixedly connected to the top of the sliding frame 62, and a second electromagnetic block 65 fixedly connected to the top inner wall of the first through hole.

[0043] When the first pressure roller 6 and the second pressure roller 61 provided by the present invention are used, in order to ensure that both the first pressure roller 6 and the second pressure roller 61 are in close contact with the gauze during the clamping process, the first electromagnetic block 64 and the second electromagnetic block 65 are activated. The first electromagnetic block 64 and the second electromagnetic block 65 have the same magnetism. According to the principle of like poles repelling each other, the sliding frame 62 is pushed towards the gauze and in close contact with the gauze, preventing the disinfectant in the second disinfection box 3 from splashing into the pretreatment box 1. At the same time, the second through hole, the first through hole and the second through hole are all provided with clamping mechanisms. The structure is the same as the clamping mechanism in the first through hole, and they are all used to isolate adjacent boxes to facilitate disinfection and drying.

[0044] Working principle: First, the first motor 12 is turned on, and the output shaft of the first motor 12 drives the unwinding shaft 11 to rotate. The unwinding shaft 11 drives the gauze to rotate and unwind. During the rotation of the unwinding shaft 11, the first gear 14 rotates, and the first gear 14 drives the second gear 15 to rotate in the opposite direction. The second gear 15 drives the connected cleaning roller 18 to rotate. The cleaning roller 18 drives the first belt 17 to rotate through the connected first rotating wheel 16. The first belt 17 drives the other two first rotating wheels 16 to rotate, and the first rotating wheels 16 drive the cleaning roller 18 to rotate. Thus, the cleaning roller 18 and the unwinding shaft 11 rotate in opposite directions, which facilitates the multi-angle peeling of attached lint, fiber debris and other physical impurities from the surface of the gauze. This significantly reduces the pollutants remaining in the gauze roll and solves the defect that traditional ultraviolet disinfection cannot remove physical impurities. The cleaning roller 18 drives the connected rotating wheel to rotate, which in turn drives the third belt 27 to rotate. The third belt 27 drives the third rotating wheel 26 to rotate, which in turn drives the connected shaft 23 to rotate. The connected shaft 23 drives the second rotating wheel 24 to rotate, which in turn drives another second rotating wheel 24 to rotate via the second belt 25. This, in turn, drives the other connected shaft 23 to rotate, which in turn drives the rotating rod 22 to rotate. The rotating rod 22 then drives the actuating rod 21 to rotate around the connected shaft 23. The actuating rod 21 rotates up and down to beat the gauze, which helps the gauze to come into contact with the disinfectant. Sufficient contact is achieved for disinfection. Periodic agitation causes the gauze fibers to repeatedly expand and contract, forcing the disinfectant to penetrate deep into the fabric's gaps, making it particularly suitable for densely woven medical gauze. Furthermore, the agitator 21 breaks the static adsorption layer of disinfectant on the gauze surface, maintaining effective contact between fresh disinfectant and the gauze, avoiding blind spots in sterilization caused by localized depletion. The cleaning roller 18 can be a soft-bristled brush roller for deep cleaning of fine dust, or a silicone polishing roller to improve the gauze's smoothness. An infrared turbidity sensor integrated into the shaft end of the cleaning roller 18 monitors the cleanliness of the gauze surface in real time; when contaminants exceed the standard, an alarm should be triggered to replace the cleaning roller 18. When heating is required, the heating tube 37 and the exhaust fan 36 are powered on. The heating tube 37 emits heat, which is blown onto the gauze by the exhaust fan 36, which is beneficial for drying the gauze. Then, the gauze is irradiated with ultraviolet light by the ultraviolet lamp tube 33 to achieve the effect of secondary disinfection.

[0045] The gauze is conveyed downwards via the third guide roller 41 and the limiting roller 411. During the conveying process, cutting is required. Because both ends of the limiting roller 411 are supported by the first spring 415, the slider 414 pushes the limiting roller 411 to one side of the third guide roller 41, clamping the gauze and preventing it from rebounding during cutting, which would be detrimental to the next winding and cutting. When winding is required, the electric push rod 435 pushes the mounting frame 432 and the clamping roller 43 to both sides of the gauze. Then, the motor is turned on, and the output group of the motor drives the bidirectional ball screw 433 to rotate. The bidirectional ball screw 433 drives the moving plate 431 to move towards the gauze until it is clamped. Then, the third motor 437 is turned on, and the output shaft of the third motor 437 drives the rotating plate 436, the electric push rod 435, the mounting frame 432, and the clamping roller 43 to rotate for winding. Once the appropriate thickness is reached, the distance sensor... When the device 44 detects the set value, it can control the third motor 437 to turn off and the second motor 424 to turn on. The output shaft of the second motor 424 drives the reciprocating screw 42 to rotate, which in turn drives the mounting plate 422 to move. The mounting plate 422 then drives the cutting blade 423 to move, cutting the gauze. After the gauze is cut, the electric push rod 435 is activated to retract it. During the retraction process, the gauze falls into the storage box 5 and then slides to one end of the storage box 5 via the inclined plate 51 for easy removal.
