Description

Technical Field

[0001] This invention relates to the field of medical waste collection devices, and specifically to a medical film-type waste treatment device. Background Technology

[0002] In the medical field, disposable sterile drapes are a common medical supply, widely used in various hospital departments such as obstetrics and gynecology, infectious diseases, internal medicine, and surgery. These sterile drapes are mainly used to cover examination beds and chairs to ensure the cleanliness and hygiene of the medical environment. Currently, common disposable sterile drapes are made of non-woven fabric and PE film. Non-woven fabric drapes are thicker than PE film drapes, but are also more expensive and are widely used in various surgical scenarios; while PE film drapes are mostly used in outpatient examination rooms of various hospital departments. Currently, PE film sterile drapes are frequently used in the obstetrics and gynecology examination room of our hospital. In practical application, the inventor found that it is difficult to collect the used sterile drapes, mainly for the following reasons:

[0003] Sterile drapes made of thin film are lightweight and highly susceptible to buoyancy and static electricity. When removed from the examination table, they tend to stick to the hands, making them difficult to dispose of in a trash can. Furthermore, the large size of the drapes laid on the examination table makes it difficult for them to reach the bottom of the trash can even after disposal. In outpatient examination rooms, with a high volume of patients and waste, drapes not properly disposed of can easily overflow, polluting the environment. Currently, patients are usually asked to dispose of their drapes themselves after their examinations. Many patients simply grab the drape from the examination table, throw it in, and rush off without crumpling it up or checking if it's properly disposed of. If the trash is not disposed of properly or overflows after the patient leaves, medical staff have to clean it up again, which is very inconvenient. Summary of the Invention

[0004] The present invention aims to provide a medical film waste disposal device to solve the technical problem that lightweight film-type sterile cloths are difficult to quickly throw into the trash can after use, and are also prone to overflowing from an empty trash can.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A medical film waste disposal device includes a main body, which is divided into a processing area and a collection area from top to bottom. The collection area is used to house the waste collection device, and the processing area is used to suck up the film waste and roll it into a ball. The processing area is provided with a processing channel and an installation channel. The bottom of the processing channel is connected to the collection area, and the top is connected to the outside as a waste inlet. The installation channel is connected to the middle of the processing channel. A disinfection area is provided on the side wall of the installation channel near the processing channel, and a disinfection component is provided in the disinfection area. A winding device is provided in the installation channel. The winding device includes a housing, a negative pressure roller slidably disposed in the housing, and a drive mechanism for driving the negative pressure roller to rotate and extend. One end of the negative pressure roller extends out of the housing and into the processing channel, and the part of the negative pressure roller extending into the processing channel is provided with several negative pressure holes for adsorbing the film waste at the waste inlet onto the negative pressure roller. When the negative pressure roller retracts into the housing, the surface of the negative pressure roller contacts the disinfection component.

[0007] Beneficial effects:

[0008] 1. The film waste disposal device of this application includes a collection area and a processing area. The collection area is used to place waste collection devices, including garbage bags and garbage bins. When in use, film waste is thrown into the processing area, where it is automatically rolled into a ball and sent to the collection area for storage, facilitating subsequent unified processing. This solves the existing technical problems of film waste being difficult to throw into garbage bins and prone to overflow due to factors such as static electricity and air buoyancy. This application automatically rolls the waste into a ball in the processing area, which reduces the risk of contamination compared to manually rolling it into balls, making it cleaner and more hygienic. In addition, this device can be used to process film waste in multiple departments of hospitals, making it highly practical. Moreover, compared to improving the structure of the garbage bins themselves, the operating cost is lower.

[0009] 2. In use, simply throw the waste into the waste inlet at the top. The negative pressure roller generates negative pressure, sucking the waste into the processing channel and adhering it to the negative pressure roller. At this time, the drive mechanism drives the negative pressure roller to rotate, rolling the film into a ball. Then, the negative pressure is stopped and the negative pressure roller is retracted. Due to the obstruction of the installation channel wall, the balled film leaves the negative pressure roller and falls down along the processing channel to the collection area under the action of gravity. Setting the negative pressure hole on the negative pressure roller ensures that the film adheres to the roller and rotates into a ball when the negative pressure roller rotates, solving the problem of the film slipping on the negative pressure roller.

[0010] 3. A disinfection zone is set up on the installation channel. When the negative pressure roller is retracted, it comes into contact with the disinfection component, thereby automatically disinfecting the negative pressure roller. That is, each time the negative pressure roller rolls up a piece of used film waste, it can be disinfected when the waste is released, making it cleaner and more hygienic to use.

[0011] Preferably, as an improvement, a sliding cavity is provided inside the housing, and the driving mechanism includes a telescopic component and a rotating component. The power output end of the telescopic component is connected to the rotating component. The telescopic component is fixedly disposed at the end of the sliding cavity away from the processing channel, and the rotating component is slidably disposed inside the sliding cavity. The rotating component includes a mounting shell, and the end of the negative pressure roller away from the processing channel extends through the mounting shell into the sliding cavity. The negative pressure roller is rotatably connected to the mounting shell, and a rotating drive component for driving the negative pressure roller to rotate is also provided inside the mounting shell.

[0012] Beneficial effects: When the film waste is adsorbed onto the negative pressure roller, the rotary drive component drives the negative pressure roller to rotate. Since the negative pressure roller is rotatably connected to the mounting shell, the mounting shell will not rotate. When it is necessary to retract the negative pressure roller to release the clump of waste, the telescopic component drives the entire rotating component to slide in the sliding cavity, thereby driving the negative pressure roller to retract.

[0013] Preferably, as an improvement, the rotary drive component includes a motor, a drive gear, and a driven gear. The drive gear is fixedly connected to the power output shaft of the motor, and the driven gear is mounted on the negative pressure reel and meshes with the drive gear. The negative pressure reel is rotatably connected to the mounting housing via bearings.

[0014] Beneficial effects: Connecting the negative pressure roller to the mounting housing via bearings not only supports the negative pressure roller, making it an integral part of the mounting housing and facilitating the telescopic assembly to extend and retract the negative pressure roller, but also reduces friction between the negative pressure roller and the mounting housing, thus improving its service life.

[0015] Preferably, as an improvement, a limiting groove is also provided on the side wall of the sliding cavity, and a limiting block is provided on the mounting shell, with the limiting block slidably disposed in the limiting groove.

[0016] Beneficial effects: The limiting groove and limiting block limit the mounting shell, preventing it from rotating and improving its stability and service life.

[0017] Preferably, as an improvement, a negative pressure channel is provided inside the negative pressure reel. One end of the negative pressure channel is connected to a negative pressure hole, and the other end passes through the end of the negative pressure reel. A connector is provided at the end, and a negative pressure tube is rotatably provided on the connector. The negative pressure tube extends out of the housing to the outside for connection with a negative pressure generator.

[0018] Beneficial effects: The rotatable connection between the negative pressure tube and the connector solves the problem of the negative pressure tube winding and tangling when the negative pressure roller rotates, thus improving the service life of the negative pressure tube; the negative pressure tube can be connected to the negative pressure system of the hospital to provide negative pressure, or a negative pressure exhaust fan or a small vacuum machine can be set on the outside of the main body to generate negative pressure in the processing channel, so that the film waste is quickly sucked into the processing channel.

[0019] Preferably, as an improvement, the disinfection component includes a sponge and a storage bottle. The sponge is placed on the side wall of the installation channel and contacts the negative pressure roller. The storage bottle is placed in the disinfection area, and a drip hole is provided on the mouth of the storage bottle, which contacts the sponge.

[0020] Beneficial effects: When in use, the disinfectant in the storage bottle automatically soaks into the sponge through the drip hole. When the negative pressure roller extends or retracts, it comes into contact with the sponge, thereby wiping the disinfectant on the sponge onto the negative pressure roller, achieving automatic disinfection.

[0021] Preferably, as an improvement, the processing area includes two parts from top to bottom: a cover and a main body. The installation channel, the winding device, and the disinfection area are located on the main body. The installation channel is closed by the cover, and the winding device is detachably installed in the installation channel.

[0022] Beneficial effects: The main body and the cover are designed to facilitate the disassembly and assembly of the winding device for maintenance and repair, and also to facilitate the replacement of the liquid storage bottle.

[0023] Preferably, as an improvement, the disinfection area is provided with a connecting channel, the bottom of which is connected to the installation channel, and a spring is provided at the top of the connecting channel. The mouth of the liquid storage bottle extends through the spring to the connecting channel, and the sponge is fixed on the mouth of the bottle without contacting the negative pressure roller. The cap is provided with a clearance groove to avoid the body of the liquid storage bottle, and a pressing rod to squeeze the liquid storage bottle. The sponge on the liquid storage bottle is brought into contact with the negative pressure roller by adjusting the pressing rod.

[0024] Beneficial effects: Setting the above settings allows for the disinfection of the negative pressure roller when needed, such as disinfecting the negative pressure roller once a day, to suit different scenarios.

[0025] Preferably, as an improvement, the pressing rod is L-shaped, and the pressing rod includes an adjusting end and a pressing end. The short side of the "L" of the pressing rod is the pressing end, which extends into the recess and is located above the liquid storage bottle. The long side of the "L" of the pressing rod extends to the outer wall of the cap as the adjusting end and is threadedly connected to the cap. When the adjusting end of the pressing rod is rotated, the pressing end is used to squeeze the liquid storage bottle downward, so that the sponge contacts the roller.

[0026] Beneficial effects: When it is necessary to disinfect the negative pressure roller, simply rotate the pressing rod to bring the sponge into contact with the negative pressure roller. At this time, the drive assembly can be used to drive the negative pressure roller to rotate and extend, so as to achieve comprehensive disinfection of the negative pressure roller alone. After disinfection, rotate the pressing rod in the opposite direction to remove the sponge from the negative pressure roller. The operation is simple and convenient.

[0027] Preferably, as an improvement, the adjustment end is provided with a knob, and the knob is provided with an indicator area.

[0028] Beneficial effects: The marking area can be used to guide users and help operators understand that different rotation angles correspond to different disinfection methods. Attached Figure Description

[0038] The following detailed description illustrates the specific implementation method:

[0039] The reference numerals in the accompanying drawings include: body 1, processing area 11, cover 111, clearance groove 1110, main body 112, collection area 12, waste collection device 121, processing channel 21, waste inlet 210, second inlet 211, scraper 211, installation channel 22, winding device 3, shell 31, sliding cavity 311, limiting groove 3110, limiting block 3111, negative pressure roller 32, negative pressure hole 320, negative pressure channel 321, connector 322, negative pressure pipe 323, telescopic component 33, mounting shell 34, bearing 340, motor 341, driving gear 342, driven gear 343, disinfection area 4, liquid storage bottle 41, sponge 42, connecting channel 5, spring 51, pressing rod 6, pressing end 61, adjusting end 62, knob 621, cylinder 7, push plate 71.

[0040] Example 1 is basically as shown in the attached document. Figure 1-3 As shown:

[0041] A medical film-type waste disposal device, such as Figure 1As shown, the device includes a main body 1, which can be a cylindrical or square structure. The main body 1 is divided into a processing area 11 and a collection area 12 from top to bottom. The processing area 11 is used to suck up thin film-like waste and roll it into a ball, while the collection area 12 is used to place a waste collection device 121. In this embodiment, the collection area 12 is hollowed out, with support columns on both sides, allowing existing waste collection devices 121, such as trash cans or trash bags, to be placed directly inside. If trash bags are placed directly, clamping elements can be provided at the bottom of the processing area 11 to hold the bag opening. Alternatively, the main body 1 can be directly installed on top of an existing large cylindrical trash can.

[0042] Processing area 11 is set with such Figure 2 The vertical processing channel 21 and the horizontal installation channel 22 are shown. The bottom of the processing channel 21 is connected to the collection area 12, and the top is connected to the outside as a waste inlet 210. In this embodiment, the waste inlet 210 is set in a cone shape to facilitate the disposal of waste into the inlet. The installation channel 22 is connected to the middle of the processing channel 21. The installation channel 22 is provided with a winding device 3 and a disinfection area 4 in sequence towards the processing channel 21. Figure 3 As shown, the winding device 3 includes a housing 31, a negative pressure roller 32 slidably disposed within the housing 31, and a drive mechanism for driving the negative pressure roller 32 to rotate and extend. One end of the negative pressure roller 32 extends out of the housing 31 and into the processing channel 21, and the portion of the negative pressure roller 32 extending into the processing channel 21 is provided with a plurality of negative pressure holes 320 for adsorbing the film waste at the waste inlet 210 onto the negative pressure roller 32. A scraper 211 is also provided on the processing channel 21, and the scraper 211 abuts against the surface of the negative pressure roller 32 and is slidably connected to the negative pressure roller 32. When the negative pressure roller 32 retracts into the mounting channel 22 to release the clumps of film waste, the scraper 211 can better detach the clumps of film waste from the negative pressure roller 32, thereby allowing it to fall from the processing channel 21 into the collection area 12. In other embodiments besides this one, in order to better facilitate the falling of clumps of waste from the processing channel 21, a positive pressure air supply system can be provided on the side wall of the processing channel 21.

[0043] Specific examples Figure 3As shown, a sliding cavity 311 is provided inside the housing 31. The driving mechanism includes a telescopic component 33 and a rotating component. The power output end of the telescopic component 33 is connected to the rotating component. The telescopic component 33 is fixedly disposed at the end of the sliding cavity 311 away from the processing channel 21. In this embodiment, the telescopic component 33 is a cylinder. The rotating component is slidably disposed inside the sliding cavity 311. The rotating component includes a mounting shell 34. The end of the negative pressure roller 32 away from the processing channel 21 extends through the mounting shell 34 into the sliding cavity 311. The negative pressure roller 32 is rotatably connected to the mounting shell 34. A rotating drive component for driving the negative pressure roller 32 to rotate is also provided inside the mounting shell 34. To prevent the mounting shell 34 from rotating inside the sliding cavity 311, a limiting groove 3110 is also provided on the side wall of the sliding cavity 311 in this embodiment. A limiting block 3111 is provided on the mounting shell 34. The limiting block 3111 is slidably disposed in the limiting groove 3110.

[0044] The rotary drive component includes a motor 341, a drive gear 342, and a driven gear 343. The drive gear 342 is fixedly connected to the power output shaft of the motor 341. The driven gear 343 is fixed on the negative pressure roller 32 and meshes with the drive gear 342. The negative pressure roller 32 is rotatably connected to the mounting housing 34 via a bearing 340. Connecting the negative pressure roller 32 to the mounting housing 34 via the bearing 340 not only provides support for the negative pressure roller 32, making the negative pressure roller 32 and the mounting housing 34 a single unit, facilitating the extension and retraction of the negative pressure roller 32 by the telescopic component 33, but also reduces friction between the negative pressure roller 32 and the mounting housing 34, thereby improving service life. A negative pressure channel 321 is provided inside the negative pressure roller 32. One end of the negative pressure channel 321 is connected to several negative pressure holes 320, and the other end passes through the end of the negative pressure roller 32. The end is provided with a connector 322, which is a rotary joint. The negative pressure pipe 323 is rotatably connected to the negative pressure channel 321 by the rotary joint. The negative pressure pipe 323 extends out of the housing 31 to the outside for connection with the negative pressure generator. The negative pressure generator can be a hospital's negative pressure system, or a negative pressure exhaust fan or a small vacuum machine can be installed outside the main body 1 to generate negative pressure on the processing channel 21, so that the membrane waste is quickly sucked into the processing channel 21.

[0045] like Figure 2 As shown, a disinfection assembly is installed in the disinfection zone 4. Specifically, the disinfection assembly includes a sponge 42 and a storage bottle 41. The sponge 42 is placed on the side wall of the installation channel 22 and contacts the negative pressure roller 32. The storage bottle 41 is placed upside down in the disinfection zone 4. A drip hole is provided on the mouth of the storage bottle 41, and the drip hole contacts the sponge 42. When in use, the disinfectant in the storage bottle 41 automatically soaks into the sponge 42 from the drip hole. When the negative pressure roller 32 extends or retracts, it contacts the sponge 42, thereby wiping the disinfectant on the sponge 42 onto the negative pressure roller 32, thus achieving automatic disinfection.

[0046] The method of using a medical film-type waste disposal device is as follows:

[0047] When the used film waste needs to be disposed of, it is thrown into the waste inlet 210 at the top of the processing area 11. To facilitate the activation of the winding device 3, a foot pedal start switch (not shown in the figure) can be installed at the bottom of the main body 1. After pressing the start switch, the negative pressure system is activated, and a negative pressure zone is formed in the processing channel 21. The film is sucked into the processing channel 21 and adsorbed onto the negative pressure roller 32. At this time, the motor 341 drives the negative pressure roller 32 to rotate, and the film waste rotates along with it and is rolled into a ball. After being rolled into a ball, the negative pressure is turned off, and the telescopic component 33 drives the negative pressure roller 32 to retract. During the retraction of the negative pressure roller 32, with the assistance of the scraper 211, the ball of waste is detached from the negative pressure roller 32 and then falls from the processing channel 21 into the waste bin in the collection area 12. During the retraction of the negative pressure roller 32, it comes into contact with the sponge 42, thereby wiping the disinfectant on the sponge 42 onto the negative pressure roller 32, realizing automatic disinfection and making it cleaner and more hygienic to use.

[0048] Example 2

[0049] The difference between this embodiment and Embodiment 1 is that, as Figure 4 As shown, the processing area 11 consists of two parts from top to bottom: a cover 111 and a main body 112. One side of the cover 111 is hinged to the main body 112. A conical waste inlet 210 is provided on the cover 111, and a processing channel 21 is provided on the main body 112. The waste inlet 210 corresponds to the processing channel 21. The installation channel 22, the winding device 3, and the disinfection area 4 are also provided on the main body 112. The top of the installation channel 22 and the top of the disinfection area 4 are both open. The installation channel 22 is closed by the cover 111. The winding device 3 is fixed in the installation channel 22 by bolts for easy disassembly, maintenance, or repair. The disinfection bottle is placed upside down in the disinfection area 4 for easy replacement.

[0050] Example 3

[0051] The difference between this embodiment and Embodiment 2 is that, as Figure 5-6 As shown, the disinfection area 4 is provided with a connecting channel 5. The bottom of the connecting channel 5 is connected to the installation channel 22. A spring 51 is provided at the top of the connecting channel 5. The mouth of the liquid storage bottle 41 extends through the spring 51 to the connecting channel 5. The sponge 42 is fixed on the mouth of the bottle and does not contact the negative pressure roller 32. The body of the liquid storage bottle 41 is higher than the top of the main body 112. The cover 111 is provided with a clearance groove 1110 to avoid the body of the liquid storage bottle 41 and a pressing rod 6 to squeeze the liquid storage bottle 41. By adjusting the pressing rod 6, the sponge 42 on the liquid storage bottle 41 is brought into contact with the negative pressure roller 32, thereby realizing the disinfection of the negative pressure roller 32 when needed.

[0052] Specific examples Figure 7 As shown, the pressing rod 6 is L-shaped and includes an adjusting end 62 and a pressing end 61. The short side of the "L" of the pressing rod 6 is the pressing end 61, which extends into the recess 1110 and is located above the liquid storage bottle 41. The long side of the "L" of the pressing rod 6 extends from the recess 1110 to the outer wall of the cover 111 as the adjusting end 62, and is threadedly connected to the cover 111. In this embodiment, the adjusting end 62 is provided with a knob 621, and the knob 621 is provided with an identification area. When it is necessary to disinfect the negative pressure roller 32, rotating the pressing rod 6 will make the sponge 42 contact the negative pressure roller 32. At this time, the driving component can be used to drive the negative pressure roller 32 to rotate and extend, so as to achieve comprehensive disinfection of the negative pressure roller 32 alone. After disinfection, the pressing rod 6 is rotated in the opposite direction to make the sponge 42 leave the negative pressure roller 32. The operation is simple and convenient, and it can be applied to scenarios with different disinfection requirements, thereby improving the service life of the disinfection structure.

[0053] Example 4

[0054] The difference between this embodiment and Embodiment 1 is that, as Figure 8 As shown, the processing area 11 is provided with a second inlet 211. The bottom of the second inlet 211 is connected to the collection area 12. Other waste, except for film waste, can be thrown in through the second inlet 211, such as cotton swabs, tissues and other waste.

[0055] Example 5

[0056] The difference between this embodiment and Embodiment 1 is that, as Figure 9 As shown, a sealing assembly is provided at the bottom of the processing area 11. The sealing assembly includes a cylinder 7 and a push plate 71. The cylinder 7 is fixed to the bottom of the processing area 11, and the piston rod of the cylinder 7 is fixedly connected to the push plate 71, used to push the push plate 71 to close or open the processing channel 21. Specifically, when the negative pressure hole 320 on the negative pressure roller 32 generates negative pressure, the cylinder 7 pushes the push plate 71 to close the bottom of the processing channel 21. When the negative pressure roller 32 rolls the film into a ball and extends into the installation channel 22 to release the film, the piston rod of the cylinder 7 retracts, pulling the push plate 71 back. At this time, the bottom of the processing channel 21 opens, and the rolled-up film waste falls from the processing channel 21 into the collection area 12. By setting up the sealing assembly, the problem of the processing channel 21 generating negative pressure and sucking up the waste in the collection area 12 when there is a lot of waste in the collection area 12 can be avoided.
