Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a closed operating room waste collection device. Background Technology

[0002] Operating rooms, as highly sterile environments in medical procedures, play a crucial role in hospital infection control and environmental protection through waste management. However, traditional operating room waste collection devices have certain limitations in practical use, particularly in terms of waste sealing, ease of handling garbage bags, and waste treatment efficiency, all of which require improvement.

[0003] Traditional waste collection systems typically employ an open design, leaving garbage bags directly exposed to the air. Waste at the bag opening area can easily emit odors or generate aerosols, impacting air quality in the operating room and potentially increasing the risk of infection for medical staff and patients. Furthermore, the filling process often requires manually opening the four corners to maximize volume, a cumbersome procedure that can expose the bags to contaminants and increase the likelihood of cross-infection. Sealing the garbage bags after collection is also complex, requiring medical staff to manually pinch the opening and seal it with a tie, which is time-consuming and prone to secondary contamination.

[0004] Furthermore, waste adhering to the inside of the garbage bag often fails to completely slide to the bottom, affecting the cleanliness of waste collection and the full utilization of the bag's internal space. At the same time, gases inside the garbage bag can easily leak out, potentially releasing harmful gases into the operating room environment and posing a threat to the health of medical staff.

[0005] To address this, we have developed a closed-loop operating room waste collection device designed to maximize the sterility, convenience, and efficiency of the waste collection process. This device features an internal mechanism that automatically opens the four corners of the waste bag, eliminating the need for medical staff to manually adjust the bag opening, simplifying the process and preventing direct contact with contaminants. When the cover is opened, the device automatically closes the top of the waste bag, reducing the exposed area of ​​waste in the air and effectively controlling odor diffusion and aerosol pollution. It also facilitates subsequent manual sealing of the waste bag. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a closed operating room waste collection device.

[0007] The objective of this invention is achieved as follows: a closed operating room waste collection device includes a box body, the bottom of which is provided with multiple casters, a side panel is provided on the front side of the box body, the side panel is foldable and connected to the box body, a placement rack is provided at the bottom of the box body that can move back and forth, the placement rack has an L-shaped structure, a cover plate is provided on the top of the box body that can rotate, a disposal port is provided on the cover plate, and two foldable opening plates are symmetrically arranged at the disposal port.

[0008] Furthermore, each of the opening and closing plates is provided with a spring rod on its lower outer side. The outer end of the spring rod is rotatably connected to the lower surface of the cover plate, and a torsion spring is provided between the spring rod and the cover plate.

[0009] Furthermore, the upper part of the inner end of the spring rod protrudes upward, and when the spring rod is not subjected to external force, its protruding part is in contact with the lower surface of the opening and closing plate.

[0010] Furthermore, a clamping mechanism is provided on the upper part of the box body. The clamping mechanism includes two symmetrically distributed guide rods, and each guide rod is provided with two clamping mechanisms that can move back and forth.

[0011] Furthermore, the two clamping mechanisms on each guide rod are symmetrically distributed, and the two clamping mechanisms move synchronously in opposite directions when moving on the guide rod.

[0012] When using this invention, the cover is opened. Simultaneously, the rear end of the cover is rotatably connected to the upper rear end of the container. As the cover rotates backward, it drives the rear ends of traction rope one and traction rope two to move backward simultaneously, meaning the backward movement distances are equal. As the rear ends of traction rope one and traction rope two move backward, they simultaneously move the symmetrically distributed moving blocks to the center of the guide rod. At this time, spring one is compressed, thus ensuring that all four moving blocks inside the container are located in the center of the guide rod. This facilitates pressing the garbage bag against its four corners using the pressure plate. The garbage bag is placed inside the container, and the sleeve is pulled upward to move the pressure plate upward away from the moving blocks. Then, the four corners of the garbage bag are placed on the corresponding moving blocks. The sleeve is released, and under the elastic force of spring two, the sleeve and pressure plate move downward. The pressure plate, in conjunction with the upper surface of the moving blocks, clamps the garbage bag. By rotating the sleeve, the position of the sleeve relative to the moving rod can be adjusted, thereby changing the pressure on spring two and adjusting the clamping force on the garbage bag.

[0013] After the garbage bag is clamped, the cover is reset. During the reset process, the two moving blocks move in opposite directions due to the elastic force of spring one, which in turn drives traction rope one and traction rope two to reset. At the same time, it moves the four corners of the garbage bag away, thus automatically opening the garbage bag. When it is necessary to remove the garbage bag, the cover is opened, and the front and rear corners of the garbage bag move towards the middle, reducing the opening area of ​​the garbage bag (or making it close to completely closed) to prevent a large amount of gas from escaping from the garbage bag, and at the same time reducing the exchange of air between the outside and the inside of the garbage bag.

[0014] After the garbage bag is placed, the controller controls the telescopic electric cylinder two to drive the transmission rod to rotate, causing the two placement frames to move closer to the center. One of the rollers on the two placement frames squeezes against each other to close the middle of the garbage bag (this prevents a large amount of gas from escaping when there is garbage at the bottom of the garbage bag). The garbage is placed on the opening and closing plate, and the opening and closing plate rotates downward under the weight of the garbage. That is, when the opening and closing plate is not filled with garbage, the spring rod can just lift the opening and closing plate upward to keep it horizontal. The spring rod is squeezed downward and rotates downward. The torsion spring is stressed, and the garbage slides into the garbage bag in the garbage can under its own weight. The opening and closing plate loses the weight of the garbage, and the torsion spring drives the spring rod to reset, which in turn drives the opening and closing plate to reset, thus closing the container.

[0015] When the garbage falls into the garbage bag inside the bin, the two rollers seal the middle of the garbage bag, causing the garbage to remain in the garbage bag above the rollers. When a certain amount of garbage has accumulated in the middle of the garbage bag (or for a certain period of time, the specific amount or time identification method is not technically limited and is existing technology), the controller controls the telescopic electric cylinder to drive the rotating rod to rotate, causing the two rollers to squeeze and close the upper part of the garbage bag towards the middle, preventing a large amount of gas from escaping from the garbage bag when the rollers squeeze the garbage downwards. Then, the telescopic electric cylinder drives the transmission rod to reset for a certain period of time (allowing the garbage in the garbage bag to move downwards under its own weight), and then controls the rollers to move towards the middle, while simultaneously controlling the drive motor to rotate, which in turn drives the placement plate to rotate. Secondly, when the placement plate rotates, there is a certain gap between the two rollers to avoid motion interference (the specific control method can be controlled by controlling the extension length of the telescopic electric cylinder, which will not be elaborated on technically). Then, the drive motor is controlled to rotate the placement frame. The side of the placement frame closest to the garbage bag rotates downwards. While the two rollers on the placement frame rotate, they can squeeze the garbage in the garbage bag downwards and move it downwards. At the same time, the servo motor is controlled to rotate, which in turn drives the lifting rod to move downwards. This allows the rollers to move downwards while following the rotation of the placement frame, which can better move the garbage adhering to the inside of the garbage bag downwards. (Note that the minimum downward distance of the rollers is higher than the maximum capacity height of the garbage bag to avoid the garbage bag bursting while squeezing the garbage downwards). When the lifting rod moves to the lowest height, the controller controls the lifting rod to reset, and then controls the rotating rod to reset. At this time, the two rollers on the left and right sides still relatively squeeze and seal the middle of the garbage belt. When garbage is put in again, it will not cause a large amount of gas to escape from the bottom of the garbage bag, and at the same time, it will prevent the garbage at the bottom of the garbage bag from being exposed to the outside air.

[0016] When the garbage bag needs to be emptied, open the cover to bring the four corners of the garbage bag together to reduce the exposed space of the garbage inside the bag. This also makes it easy to manually seal the four corners of the garbage bag. Then open the side panel (the side panel opens to the side) and pull out the shelf to move the garbage bag to the outside of the container for easy handling.

[0017] Beneficial effects: This device can automatically open the four corners of the garbage bag inside the container, and automatically close the upper port of the garbage bag when the cover is opened, reducing the exposed area of ​​garbage in the garbage bag to the air, while facilitating manual sealing of the garbage bag; and it is equipped with a roller that can move up and down and rotate to move the garbage adhering to the inner side of the garbage bag downwards, and the roller can reduce the leakage of gas from the garbage bag.

[0027] Example 1, as Figure 1-7 As shown, the objective of this invention is achieved as follows: A closed operating room waste collection device includes a box 1, the bottom of which is provided with multiple casters, a side plate 2 is provided on the front side of the box 1, the side plate 2 is closable and connected to the box 1, a placement rack 19 is provided at the bottom of the box 1 that can move back and forth, the placement rack 19 has an L-shaped structure, which can support the garbage bags, a cover plate 3 is rotatably provided on the top of the box 1, the cover plate 3 has a disposal port, and two closable opening plates 4 are symmetrically arranged at the disposal port.

[0028] Each hinge plate 4 has a spring rod 5 located on its lower outer side. The outer end of the spring rod 5 is rotatably connected to the lower surface of the cover plate 3, and a torsion spring is provided between the spring rod 5 and the cover plate 3. The upper part of the inner end of the spring rod 5 protrudes upward, and when the spring rod 5 is not subjected to external force, its protruding part is in contact with the lower surface of the hinge plate 4.

[0029] A clamping mechanism is provided on the upper part of the housing 1. The clamping mechanism includes two symmetrically distributed guide rods 8, and two clamping mechanisms are provided on each guide rod 8, which can move back and forth. The two clamping mechanisms on each guide rod 8 are symmetrically distributed, and the two clamping mechanisms move synchronously in opposite directions when moving on the guide rod 8.

[0030] A spring 11 is installed between the two clamping mechanisms. A traction rope 13 is fixedly installed at the lower end of the rear clamping mechanism, and a traction rope 20 is fixedly installed at the lower end of the front clamping mechanism. A guide wheel 18 is fixedly installed on the side of the housing 1, and the guide wheel 18 is placed horizontally. A guide wheel groove 1 is opened inside the rear side of the housing 1, and guide wheels 2 and 3 are rotatably installed in the guide wheel groove 1. A guide wheel groove 2 is opened at the upper part of the rear side of the housing 1, and guide wheels 4 and 5 are installed in the guide wheel groove 2. Guide wheels 2, 3, 4, and 5 are placed longitudinally. The traction rope 20 passes under the guide wheel 3, then passes over the front upper side of the guide wheel 5 and connects to the rear inner side of the cover plate 3. The traction rope 13 passes over the guide wheel 18 from the left side, then passes under the guide wheel 2, then passes over the front upper side of the guide wheel 4 and connects to the rear inner side of the cover plate 3. The guide wheels facilitate the movement of the traction ropes.

[0031] The clamping mechanism includes a movable block 12, which is slidably positioned on the guide rod 8. A movable rod 16 is longitudinally inserted through the movable block 12 and can move up and down. A spring 15 is installed between the lower end of the movable rod 16 and the lower surface of the movable block 12, and the spring 15 is fitted onto the movable rod 16. A pressure plate 9 is movable up and down on the upper part of the movable rod 16, and a sleeve rod 14 is rotatably mounted on the pressure plate 9. The lower part of the sleeve rod 14 is threadedly connected to the upper part of the movable rod 16. Multiple pressure strips are provided on the upper surface of the movable block 12 to increase the squeezing friction on the garbage bag. This application can use garbage bags with four corner openings, or the garbage opening can be evenly divided into four fixed points and fixed to four clamping mechanisms respectively. Each guide rod 8 has a horizontally arranged limit strip 7 on the inner side of the box 1. The inner side of the limit strip 7 is a smooth arc surface. Multiple rollers 6 are evenly distributed on the limit strip 7 to prevent the garbage bag opening from being damaged due to hard friction with the limit strip 7 when it is opened and closed.

[0032] The housing 1 is equipped with two symmetrical sealing mechanisms. Each sealing mechanism includes two symmetrically distributed rotating rods 29, which are rotatably connected to the housing 1. A roller 23 is rotatably mounted on the upper end of each rotating rod 29. A protective plate 20 is fixedly installed inside the housing 1 on the inner side of each sealing mechanism. The left and right sides of the protective plate 20 are fixedly connected to the housing 1. A strip groove is opened on the left and right sides of the upper part of the protective plate 20. The rotating rod 29 rotatably passes through the strip groove. A telescopic electric cylinder 30 is installed between the rear rotating rod 29 and the housing 1. The telescopic electric cylinder 30 is rotatably connected to the rotating rod 29, and its outer end is rotatably connected to the housing 1. The telescopic electric cylinder 30 drives the rotating rod 29 to rotate.

[0033] Two extrusion mechanisms are symmetrically arranged on the bottom of the box 1. Each extrusion mechanism includes two symmetrically distributed transmission rods 32. The transmission rods 32 are connected to the box 1. A placement plate 28 is rotatably mounted on the upper end of the transmission rod 32. The middle part of the placement plate 28 is rotatably connected to the upper end of the transmission rod 32. Rollers 22 are rotatably mounted on both ends of the placement plate 28. A drive motor 31 is fixedly mounted on the rear transmission rod 32. The drive motor 31 drives the placement plate 28 to rotate. A horizontally distributed strip groove 21 is opened in the middle of the protective plate 20. The placement plate 28 rotatably passes through the strip groove 21. Strip grooves 3 are opened on the protective plates 20 on the left and right sides of the strip groove 21. The transmission rod 32 rotatably passes through the strip groove 3.

[0034] The transmission rod 32 includes a telescopic rod one and a telescopic rod two. A spring three is installed between the telescopic rod one and the telescopic rod two. The two ends of the spring three are connected to the telescopic rod one and the telescopic rod two, respectively. A connecting cylinder 33 is installed between the telescopic rod one and the telescopic rod two. The telescopic rod one and the telescopic rod two are movably located inside the connecting cylinder 33. The above structure can prevent the garbage adhering to the garbage bag from being too large and unable to move downwards. In this case, the roller two 22 can move outwards due to its resistance, causing the telescopic rod one to move towards the telescopic rod two, increasing the distance between the left and right roller two 22, and preventing damage to the garbage bag.

[0035] A lifting rod 24 is provided between the transmission rod 32 and the housing 1. The lifting rod 24 and the transmission rod 32 are rotatably connected. The lifting rod 24 and the housing 1 are vertically movable. A guide rail 25 is provided between the lifting rod 24 and the housing 1. The guide rail 25 is fixedly connected to the housing 1. The lifting rod 24 is located on the guide rail 25 and can move vertically. A servo motor 26 is provided at the bottom of the housing 1. A threaded rod 27 is connected to the output end of the servo motor 26. The threaded rod 27 passes through the lifting rod 24. The rotation of the servo motor 26 drives the threaded rod 27 to rotate, thereby driving the lifting rod 24 to move vertically. A telescopic electric cylinder 34 is provided between the transmission rod 32 and the lifting rod 24. The telescopic electric cylinder 34 is rotatably connected to the transmission rod 32. A fixed seat is provided between the outer end of the telescopic electric cylinder 34 and the lifting rod 24. The fixed seat and the telescopic electric cylinder 34 are rotatably connected. The telescopic electric cylinder 34 drives the transmission rod 32 to rotate.

[0036] In use, the cover plate 3 is opened. Simultaneously, the rear end of the cover plate 3 is rotatably connected to the upper rear end of the container 1. As the cover plate 3 rotates backward, it simultaneously moves the rear ends of traction rope one 13 and traction rope two 10 backward, meaning the backward movement distances are equal. This movement of the rear ends of traction rope one 13 and traction rope two 10 also moves the symmetrically distributed moving blocks 12 to the center position of the guide rod 8. At this time, spring one 11 is compressed, thus ensuring that all four moving blocks 12 inside the container 1 are located in the center of the guide rod 8, facilitating the loading of the garbage bag. Plate 9 presses down on the four corners of the garbage bag, placing the garbage bag inside the container 1. Pulling up the sleeve rod 14 moves the pressure plate 9 upward, disengaging it from the moving block 12. Then, place the four corners of the garbage bag on the corresponding moving blocks 12. Release the sleeve rod 14, and under the elastic force of the second spring 15, the sleeve rod 14 and the pressure plate 9 move downward. The pressure plate 9, in conjunction with the upper surface of the moving block 12, clamps the garbage bag. By rotating the sleeve rod 14, the position of the sleeve rod 14 relative to the moving rod 16 can be adjusted, thereby changing the pressure on the second spring 15 and adjusting the clamping force on the garbage bag.

[0037] After the garbage bag is clamped, the cover plate 3 is reset. During the reset process, the two moving blocks 12 move in opposite directions to reset due to the elastic force of the spring 11, which drives the traction rope 13 and traction rope 2 10 to reset. At the same time, it moves the four corners of the garbage bag away, thus automatically opening the garbage bag. When it is necessary to remove the garbage bag, the cover plate 3 is opened, and the front and rear corners of the garbage bag move towards the middle, reducing the opening area of ​​the garbage bag (or tending to be completely closed) to prevent a large amount of gas from escaping from the garbage bag, and at the same time reducing the exchange of air between the outside and the inside of the garbage bag.

[0038] After the garbage bag is placed, the controller controls the telescopic electric cylinder 34 to drive the transmission rod 32 to rotate, causing the two placement racks 19 to move closer to the middle position. One of the rollers 22 on the two placement racks 19 squeezes against each other to close the middle of the garbage bag (this prevents a large amount of gas from overflowing when there is garbage at the bottom of the garbage bag). The garbage is placed on the opening and closing plate 4. The opening and closing plate 4 rotates downward under the gravity of the garbage. That is, when the opening and closing plate 4 is not placed with garbage, the spring rod 5 can just lift the opening and closing plate upward to keep it horizontal. The spring rod 5 rotates downward under the downward squeezing force, and the torsion spring is stressed. The garbage slides into the garbage bag in the garbage can under its own gravity. The opening and closing plate 4 loses the gravity of the garbage, and the torsion spring drives the spring rod 5 to reset, which in turn drives the opening and closing plate 4 to reset, thus closing the container 1.

[0039] When the garbage falls into the garbage bag inside the container 1, the two rollers 22 seal the middle of the garbage bag, causing the garbage to remain in the garbage bag above the rollers 22. When a certain amount of garbage is stored in the middle of the garbage bag (or for a certain period of time, the specific amount or time identification method is not technically limited and is existing technology), the controller controls the telescopic electric cylinder 30 to drive the rotating rod 29 to rotate, causing the two rollers 23 to squeeze and close the upper part of the garbage bag towards the middle, preventing a large amount of gas from escaping from the garbage bag when the rollers 22 squeeze the garbage downwards. Then, the telescopic electric cylinder 34 drives the transmission rod 32 to reset for a certain period of time (allowing the garbage in the garbage bag to move downwards under its own weight), and then controls the rollers 22 to move towards the middle, while simultaneously controlling the drive motor 31 to rotate, which in turn drives the placement plate 28 to rotate. When the rollers 22... 2. When the placement plate 28 rotates, there is a certain gap between the two rollers 22 on the left and right to avoid motion interference (the specific control method can be controlled by controlling the extension length of the telescopic cylinder 34, which will not be described in detail). Then, the drive motor 31 is controlled to rotate the placement frame 19. The side of the placement frame 19 closest to the garbage bag rotates downward. While the two rollers 22 on the placement frame 19 are rotating, they can squeeze the garbage in the garbage bag downward and move it downward. At the same time, the servo motor 26 is controlled to rotate, which in turn drives the lifting rod 24 to move downward. This allows the rollers 22 to move downward while rotating with the placement frame 19, which can better move the garbage adhering to the inside of the garbage bag downward. (Note that the minimum distance that the rollers 22 move downward is higher than the maximum capacity height of the garbage bag to avoid the garbage bag bursting while squeezing the garbage downward). When the lifting rod 24 moves to the lowest height, the controller controls the lifting rod 24 to reset, and then controls the rotating rod 29 to reset. At this time, the two rollers 22 on the left and right still squeeze and seal the middle of the garbage belt, so that when garbage is put in again, a large amount of gas will not leak out from the bottom of the garbage bag, and the garbage at the bottom of the garbage bag will not be exposed to the outside air.

[0040] When the garbage bag needs to be cleaned, open the cover 3 to bring the four corners of the top of the garbage bag together to reduce the exposed space of the garbage inside the garbage bag. At the same time, it is convenient to manually seal the four corners of the garbage bag. Then open the side panel 2 (the side panel 2 opens to the side) and pull out the placement rack 19 to move the garbage bag to the outside of the box 1 for easy handling.
