Abstract
Description
Technical Field
[0001] This invention relates to the field of medical waste collection technology, and more specifically to an operating room nursing waste collection device. Background Technology
[0002] After surgery, medical staff need to collect the medical waste generated during the procedure. Currently, to avoid mixing solid and liquid medical waste and accelerating the growth of bacteria and viruses, solid and liquid medical waste need to be collected separately.
[0003] For example, Chinese patent number 201910805837.6 discloses an operating room nursing waste collection device, including a box body with a partition inside the box body dividing the box body into a first cavity and a second cavity. A rotating plate that can rotate inside the box body is hinged to the upper middle part of the partition. A sealing plate that is placed above the partition is hinged to the side wall of the box body. The sealing plate can rotate on one side of the second cavity. In the initial state, the sealing plate, rotating plate, and partition are in the same vertical plane. A filter screen that is flush with the upper surface of the partition is provided on the upper part of the first cavity. The sealing plate is placed on one side of the second cavity and connected to the side wall of the box body with a compression spring. The rotation of the rotating plate can push the sealing plate to rotate towards the second cavity.
[0004] While existing operating room medical waste collection devices can separate and collect solid and liquid medical waste, the first chamber storing liquid medical waste becomes connected to the outside when the cover is opened to dispose of medical waste. At this time, bacteria in the first chamber will continuously escape. Moreover, when disposing of medical waste, most people face the disposal port, and the continuously escaping bacteria can easily infect them, reducing the safety of the device. Summary of the Invention
[0005] To address the shortcomings of existing technologies, this invention proposes an operating room nursing waste collection device that prevents the release of bacteria when disposing of medical waste and improves the safety of the device's use.
[0006] An operating room nursing waste collection device, comprising:
[0007] The cylindrical body has a storage cavity inside, and a temporary storage cavity communicating with the storage cavity is opened at the top of the cylindrical body;
[0008] A sealing mechanism includes a sealing plate, a support plate, and a first driving assembly. The sealing plate is rotatably mounted on the top surface of the cylinder via a first rotating shaft and can seal or open the top end of the temporary storage cavity. The support plate is rotatably mounted on the top surface of the storage cavity via a second rotating shaft and can seal or open the bottom end of the temporary storage cavity. The first driving assembly is mounted on the cylinder and connects the sealing plate and the support plate. Adjusting the first driving assembly allows the support plate to seal the bottom end of the temporary storage cavity before driving the sealing plate to open the top end of the temporary storage cavity, or vice versa.
[0009] A separation mechanism, disposed within the storage cavity, is used to perform solid-liquid separation of medical waste within the storage cavity.
[0010] The beneficial effects of the above-mentioned operating room nursing waste collection device are as follows:
[0011] When disposing of medical waste, the first driving component is adjusted to drive the support plate to seal the bottom of the temporary storage chamber, and then the sealing plate is driven to open the top of the temporary storage chamber. The first sealing of the bottom of the temporary storage chamber by the support plate prevents the storage chamber from communicating with the outside when the top of the temporary storage chamber is opened, thus preventing bacteria from escaping. Then, the medical waste is placed into the temporary storage chamber, where the support plate holds the medical waste. The first driving component is then adjusted again to drive the sealing plate to seal the top of the temporary storage chamber, and then the support plate is driven to open the bottom of the temporary storage chamber. The first sealing of the top of the temporary storage chamber by the support plate prevents the storage chamber from communicating with the outside when the bottom of the temporary storage chamber is opened, thus preventing bacteria from escaping. This prevents bacteria from escaping from the storage chamber during the disposal of medical waste, improving the safety of the device.
[0012] In one embodiment, the first driving assembly includes a pedal and a first transmission assembly. The pedal is vertically movable and disposed at the bottom of the cylinder, and is connected to the sealing plate and the support plate via the first transmission assembly. When the pedal moves downward, it drives the support plate to seal the bottom of the temporary storage cavity via the first transmission assembly, and then drives the sealing plate to open the top of the temporary storage cavity. When the pedal moves upward, it drives the sealing plate to seal the top of the temporary storage cavity via the first transmission assembly, and then drives the support plate to open the bottom of the temporary storage cavity. This design allows the patient to control the rotation of the sealing plate and support plate by moving the pedal up and down with their foot, freeing the hands of the disposal personnel to dispose of medical waste and improving the ease of use of the device.
[0013] In one embodiment, the first transmission assembly includes a first bevel gear, a second bevel gear, a rotating shaft, and a connecting rod. A first mounting groove is provided on the circumference of the cylinder. The first rotating shaft and the second rotating shaft both extend into the first mounting groove and are respectively provided with the first bevel gear and the second bevel gear. The rotating shaft is rotatably disposed in the first mounting groove, and one end is provided with a sector bevel gear, and the other end is provided with a transmission gear. The number of teeth of the sector bevel gear is half that of the first bevel gear and the second bevel gear. The sector bevel gear can mesh with the second bevel gear and the first bevel gear in sequence when rotated clockwise. One end of the connecting rod is connected to the pedal, and the other end is provided with a rack. The rack meshes with the transmission gear. The pedal moving downward can drive the transmission gear to rotate clockwise. Moving the pedal downwards causes the connecting rod and rack to move downwards, driving the transmission gear to rotate clockwise. This clockwise rotation of the transmission gear, through the rotating shaft, drives the sector bevel gear to rotate clockwise. The sector bevel gear meshes with the second bevel gear, driving the support plate to rotate and seal the bottom of the temporary storage cavity. After the support plate seals the bottom of the temporary storage cavity, the sector bevel gear continues to rotate and disengages from the second bevel gear. At this point, the support plate stops rotating and remains sealed at the bottom of the temporary storage cavity. When the sector bevel gear continues to rotate and meshes with the first bevel gear, its rotation drives the sealing plate to rotate, opening the top of the temporary storage cavity. Moving the pedal upwards... The upward movement of the connecting rod and rack drives the transmission gear to rotate counterclockwise. The counterclockwise rotation of the transmission gear drives the sector bevel gear to rotate counterclockwise through the rotating shaft. The counterclockwise rotation of the sector bevel gear drives the sealing plate to rotate in the opposite direction through the first bevel gear, sealing the top of the temporary storage cavity. After the sealing plate seals the top of the temporary storage cavity, the sector bevel gear continues to rotate and separates from the first bevel gear. At this time, the sealing plate stops rotating and remains in the state of sealing the top of the temporary storage cavity. When the sector bevel gear continues to rotate and meshes with the second bevel gear, the rotation of the sector bevel gear drives the bearing plate to rotate in the opposite direction through the second bevel gear, opening the bottom of the temporary storage cavity. This allows for convenient control of the sealing plate and the bearing plate to seal the temporary storage cavity separately.
[0014] In one embodiment, the first driving assembly further includes a spring; a second mounting groove is provided at the bottom of the cylinder, and multiple sets of guide posts are spaced apart in the second mounting groove. The pedal is slidably fitted onto the multiple sets of guide posts, and the spring is fitted onto each of the multiple sets of guide posts. The two ends of the spring abut against the bottom surface of the second mounting groove and the bottom end of the pedal, respectively. Stepping on the pedal moves it downwards, and the downward movement of the pedal compresses the spring. By releasing the pressure applied to the pedal, the reaction force of the spring moves the pedal upwards to return to its original position, making it convenient to drive the pedal to move up and down.
[0015] In one embodiment, the separation mechanism includes a partition, a filter screen, a movable plate, and a second drive assembly. The partition is disposed at the bottom of the storage chamber, dividing it into a liquid chamber and a solid chamber. The liquid chamber corresponds to the temporary storage chamber. The filter screen is disposed at the top of the liquid chamber, with its top surface flush with the top surface of the partition. The movable plate is located at the top of the partition and parallel to it. One end of the movable plate is provided with a drive shaft, which is rotatably disposed in the middle of the partition. The other end of the movable plate contacts the periphery of the storage chamber. The second drive assembly is disposed on the cylinder and connected to the drive shaft, driving the drive shaft to rotate. When medical waste passes through the temporary storage chamber, it falls onto the filter screen. At this time, the liquid in the medical waste falls into the liquid chamber through the filter screen, while the solid medical waste remains above the filter screen. Then, the second drive assembly is adjusted to drive the drive shaft to rotate. The rotation of the drive shaft drives the movable plate to rotate, which in turn moves the solid medical waste on the filter screen, causing it to fall into the solid chamber. This facilitates the solid-liquid separation and storage of medical waste.
[0016] In one embodiment, the second drive assembly includes a motor and a controller; the motor is disposed inside the cylinder and its output shaft is connected to the transmission shaft via a coupling; the controller is disposed on the periphery of the cylinder and is electrically connected to the motor; starting the controller once can control the output shaft of the motor to rotate one revolution.
[0017] In one embodiment, the separation mechanism further includes a pressure plate and a torsion spring; a receiving groove is provided on the periphery of the storage cavity, the pressure plate is located at the top of the partition, and one end is rotatably mounted on one end of the receiving groove via the torsion spring, while the other end rests on the movable plate. When the movable plate rotates, it moves the solid medical waste on the filter screen, allowing the solid medical waste to come into contact with the pressure plate. At this time, the rotation of the movable plate, in conjunction with the pressure plate, squeezes the solid medical waste, thereby squeezing out the liquid adsorbed in the solid medical waste, further improving the solid-liquid separation effect of the device. When the force of the movable plate rotating and moving the solid medical waste is greater than the torsion of the torsion spring, the movement of the solid medical waste drives the pressure plate to rotate. At this time, the rotation of the movable plate causes the solid medical waste to fall into the solid cavity. After the solid medical waste falls into the solid cavity, the end of the movable plate can contact the surface of the pressure plate. At this time, the rotation of the movable plate can scrape off the solid medical waste attached to the pressure plate, making it easy to clean the pressure plate.
[0018] In one embodiment, a cleaning component is further included, comprising a cleaning brush. A third mounting groove is provided at the bottom of the movable plate, and the cleaning brush is disposed within the third mounting groove, with the brush bristles capable of contacting the filter screen. By providing the cleaning brush, rotation of the movable plate causes the cleaning brush to rotate and contact the filter screen, thereby facilitating cleaning of the filter screen and making filter screen cleaning convenient.
[0019] In one embodiment, the cleaning assembly further includes a second transmission assembly; the cleaning brush is slidably disposed within the third mounting groove, and the second transmission assembly is disposed on the movable plate and connects the cleaning brush and the cylinder. The second transmission assembly converts the rotation of the movable plate into the reciprocating up-and-down movement of the cleaning brush, allowing the brush bristles of the cleaning brush to pass through the filter screen. Driving the cleaning brush to reciprocate up-and-down movement via the second transmission assembly facilitates the unblocking of the filter screen, preventing clogging. Simultaneously, when the cleaning brush rotates above the solids chamber, the reciprocating up-and-down movement of the cleaning brush shakes off any solid medical waste adhering to the cleaning brush into the solids chamber, facilitating self-cleaning of the cleaning brush.
[0020] In one embodiment, the second transmission assembly includes a tension spring, a lever, and a wedge-shaped guide block. A connecting shaft is provided at the top of the cleaning brush, extending upward through the movable plate and connected to the lever. The tension spring is sleeved on the connecting shaft, with its two ends connected to the lever and the movable plate, respectively. An annular groove is formed around the periphery of the storage cavity, and multiple sets of wedge-shaped guide blocks are spaced apart within the annular groove. One end of the lever extends into the annular groove and can move sequentially along the wedge surfaces of the multiple sets of wedge-shaped guide blocks. Rotation of the movable plate drives the lever to rotate, allowing it to contact and move along the wedge surfaces of the wedge-shaped guide blocks. This upward movement of the lever causes it to move upward, which in turn drives the cleaning brush upward via the connecting shaft, and also puts tension on the tension spring. When the lever separates from the wedge-shaped guide blocks, the reaction force of the tension spring causes the lever to move downward, which in turn drives the cleaning brush downward via the connecting shaft. This process is repeated to drive the cleaning brush to move up and down repeatedly, making the up-and-down movement of the cleaning brush convenient. Attached Figure Description

[0034] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.
[0035] Please see Figures 1 to 4 One embodiment of an operating room nursing waste collection device includes a cylinder 10, a sealing mechanism 20, and a separation mechanism 30.
[0036] The cylinder 10 has a storage cavity inside, and a temporary storage cavity 101 communicating with the storage cavity is opened at the top of the cylinder 10. The sealing mechanism 20 includes a sealing plate 201, a support plate 202, and a first driving assembly. The sealing plate 201 is rotatably disposed on the top surface of the cylinder 10 via a first rotating shaft and can seal or open the top of the temporary storage cavity 101. The support plate 202 is rotatably disposed on the top surface of the storage cavity via a second rotating shaft and can seal or open the bottom of the temporary storage cavity 101. The first driving assembly is disposed on the cylinder 10 and connects the sealing plate 201 and the support plate 202. Adjusting the first driving assembly can drive the support plate 202 to seal the bottom of the temporary storage cavity 101 and then drive the sealing plate 201 to open the top of the temporary storage cavity 101, or drive the sealing plate 201 to seal the top of the temporary storage cavity 101 and then drive the support plate 202 to open the bottom of the temporary storage cavity 101.
[0037] Specifically, the first drive assembly includes a pedal 204 and a first transmission assembly. The pedal 204 is movable up and down at the bottom of the cylinder 10 and is connected to the sealing plate 201 and the support plate 202 through the first transmission assembly. When the pedal 204 moves downward, it can drive the support plate 202 to seal the bottom of the temporary storage cavity 101 through the first transmission assembly, and then drive the sealing plate 201 to open the top of the temporary storage cavity 101. When the pedal 204 moves upward, it can drive the sealing plate 201 to seal the top of the temporary storage cavity 101 through the first transmission assembly, and then drive the support plate 202 to open the bottom of the temporary storage cavity 101. The first transmission assembly includes a first bevel gear 205, a second bevel gear 206, a rotating shaft 207, and a connecting rod 203. A first mounting groove 102 is provided on the circumference of the cylinder 10. The first rotating shaft and the second rotating shaft both extend into the first mounting groove 102 and are respectively provided with the first bevel gear 205 and the second bevel gear 206. The rotating shaft 207 is rotatably disposed in the first mounting groove 102, and one end is provided with a sector bevel gear 2071, and the other end is provided with a transmission gear 2072. The number of teeth of the sector bevel gear 2071 is half that of the first bevel gear 205 and the second bevel gear 206. When the sector bevel gear 2071 rotates clockwise, it can mesh with the second bevel gear 206 and the first bevel gear 205 in sequence. One end of the connecting rod 203 is connected to the pedal 204, and the other end is provided with a rack 2031. The rack 2031 meshes with the transmission gear 2072. When the pedal 204 moves downward, it can drive the transmission gear 2072 to rotate clockwise.
[0038] In the above embodiment, when disposing of medical waste, the foot drives the pedal 204 downward. The downward movement of the pedal 204 drives the rack 2031 downward via the connecting rod 203, which meshes with the transmission gear 2072, driving the transmission gear 2072 to rotate clockwise. The clockwise rotation of the transmission gear 2072 drives the sector bevel gear 2071 to rotate clockwise via the rotating shaft 207. The clockwise rotation of the sector bevel gear 2071 meshes with the second bevel gear 206, thereby driving the support plate 202 to rotate, so that the support plate 202 seals the bottom of the temporary storage cavity 101. When the support plate 202 seals the bottom of the temporary storage cavity 101... Afterwards, the sector bevel gear 2071 continues to rotate and separates from the second bevel gear 206. At this time, the bearing plate 202 stops rotating and remains sealed at the bottom of the temporary storage cavity 101. When the sector bevel gear 2071 continues to rotate and meshes with the first bevel gear 205, the rotation of the sector bevel gear 2071 drives the sealing plate 201 to rotate and open the top of the temporary storage cavity 101 through the first bevel gear 205. By first driving the bearing plate 202 to seal the bottom of the temporary storage cavity 101, bacteria in the storage cavity can be prevented from escaping when the sealing plate 201 opens the top of the temporary storage cavity 101. Then, medical waste is placed into the temporary storage cavity 101. At this time, the bearing plate 202... The carrier plate 202 carries medical waste, which then drives the pedal 204 to move upward. The upward movement of the pedal 204 drives the connecting rod 203 and the rack 2031 to move upward, driving the transmission gear 2072 to rotate counterclockwise. The counterclockwise rotation of the transmission gear 2072 drives the sector bevel gear 2071 to rotate counterclockwise through the rotating shaft 207. The counterclockwise rotation of the sector bevel gear 2071 drives the sealing plate 201 to rotate in the opposite direction through the first bevel gear 205, sealing the top of the temporary storage cavity 101. After the sealing plate 201 seals the top of the temporary storage cavity 101, the sector bevel gear 2071 continues to rotate and separates from the first bevel gear 205. At this time, the sealing plate 201 stops rotating and remains in the sealed top position of the temporary storage cavity 101. When the sector bevel gear 2071 continues to rotate and meshes with the second bevel gear 206, the rotation of the sector bevel gear 2071 drives the bearing plate 202 to rotate in the opposite direction through the second bevel gear 206, opening the bottom of the temporary storage cavity 101. By first driving the sealing plate 201 to seal the top of the temporary storage cavity 101, the bacteria in the storage cavity can be prevented from being released when the bearing plate 202 opens the bottom of the temporary storage cavity 101 and the medical waste falls into the storage cavity. This prevents the bacteria in the storage cavity from being released during the disposal of medical waste and improves the safety of the device.
[0039] Please see Figure 2 , Figure 3Based on the above embodiments, the first drive assembly further includes a spring 2041; a second mounting groove 103 is provided at the bottom of the cylinder 10, and multiple sets of guide posts 1031 are spaced apart in the second mounting groove 103. The pedal 204 is slidably mounted on the multiple sets of guide posts 1031, and a spring 2041 is mounted on each of the multiple sets of guide posts 1031. The two ends of the spring 2041 respectively abut against the bottom surface of the second mounting groove 103 and the bottom end of the pedal 204.
[0040] In the above embodiment, the pedal 204 can be moved downward by stepping on it. The downward movement of the pedal 204 will compress the spring 2041. By releasing the pressure applied to the pedal 204, the reaction force of the spring 2041 can move the pedal 204 upward to reset it. The pedal 204 can be moved up and down easily.
[0041] Based on the above embodiment, one end of the pedal 204 extends outside the cylinder 10, and multiple sets of anti-slip grooves 2042 are evenly provided on the top surface. The extension of the pedal 204 outside the cylinder 10 facilitates the stepping of personnel, and the multiple sets of anti-slip grooves 2042 can improve the stability of the personnel stepping on the pedal 204 and avoid slipping.
[0042] Please see Figure 3 , Figure 4 Based on the above embodiments, magnets 108 are further provided at the top of the temporary storage cavity 101 and around the top surface of the storage cavity. Iron blocks are provided on both the sealing plate 201 and the supporting plate 202. When the sealing plate 201 seals the top of the temporary storage cavity 101 and the supporting plate 202 opens the bottom of the temporary storage cavity 101, the two sets of magnets 108 are magnetically connected to the two sets of iron blocks. By setting the magnets 108 to be magnetically connected to the iron blocks, it is convenient for the device to fix the sealing plate 201 and the supporting plate 202 under normal conditions, and to prevent the device from being affected by external forces, causing the sealing plate 201 to rotate and open the top of the temporary storage cavity 101.
[0043] Please see Figure 2 , Figure 3 , Figure 5In one embodiment, the separation mechanism 30 is disposed within the storage cavity for solid-liquid separation of medical waste within the storage cavity. Specifically, the separation mechanism 30 includes a partition 301, a filter 302, a moving plate 303, and a second drive assembly. The partition 301 is disposed at the bottom of the storage cavity, dividing the storage cavity into a liquid cavity 104 and a solid cavity 105. The liquid cavity 104 corresponds to the temporary storage cavity 101. The filter 302 is disposed at the top of the liquid cavity 104, with its top surface flush with the top surface of the partition 301. The moving plate 303 is located at the top of the partition 301 and is parallel to the partition 301. One end of the moving plate 303 is provided with a drive shaft 3031, which is rotatably disposed in the middle of the partition 301. The other end of the moving plate 303 contacts the periphery of the storage cavity. The second drive assembly is disposed on the cylinder 10 and connected to the drive shaft 3031, for driving the drive shaft 3031 to rotate. The second drive assembly includes a motor 305 and a controller 304. The motor 305 is disposed inside the cylinder 10, and its output shaft is connected to the transmission shaft 3031 via a coupling. The controller 304 is disposed on the circumference of the cylinder 10 and is electrically connected to the motor 305. Starting the controller 304 once controls the output shaft of the motor 305 to rotate one revolution. Specifically, in this embodiment, both the controller 304 and the motor 305 are existing technologies and will not be described in detail.
[0044] In the above embodiment, when medical waste passes through the temporary storage chamber 101, it falls onto the filter screen 302. At this time, the liquid in the medical waste falls into the liquid chamber 104 through the filter screen 302, while the solid medical waste remains above the filter screen 302. Then, the controller 304 is activated to control the output shaft of the motor 305 to rotate one revolution. One revolution of the output shaft of the motor 305 drives the moving plate 303 to rotate one revolution through the transmission shaft 3031. The rotation of the moving plate 303 can move the solid medical waste on the filter screen 302, so that the solid medical waste falls into the solid chamber 105, thereby facilitating the solid-liquid separation of medical waste. After the solid medical waste falls into the solid chamber 105, the moving plate 303 rotates one revolution to reset, so that the controller 304 can be activated again to move the solid medical waste.
[0045] Based on the above embodiments, the separation mechanism 30 further includes a pressure plate 306 and a torsion spring 307; a storage groove 106 is provided on the periphery of the storage cavity, the pressure plate 306 is located at the top of the partition 301, and one end is rotatably disposed at one end of the storage groove 106 by the torsion spring 307, while the other end is placed on the movable plate 303.
[0046] In the above embodiments, when the moving plate 303 rotates and moves the solid medical waste on the filter screen 302, the solid medical waste can come into contact with the pressure plate 306. At this time, the rotation of the moving plate 303 and the cooperation of the pressure plate 306 can squeeze the solid medical waste, thereby squeezing out the liquid adsorbed in the solid medical waste, further improving the effect of solid-liquid separation of medical waste by the device. When the force of the moving plate 303 rotating and moving the solid medical waste is greater than the torque of the torsion spring 307, the movement of the solid medical waste drives the pressure plate 306 to rotate. At this time, the rotation of the moving plate 303 and the movement of the solid medical waste can make the solid medical waste fall into the solid cavity 105. After the solid medical waste falls into the solid cavity 105, the end of the moving plate 303 can contact the surface of the pressure plate 306. At this time, the rotation of the moving plate 303 can scrape off the solid medical waste attached to the pressure plate 306, making it easy to clean the pressure plate 306.
[0047] Please see Figure 2 , Figure 6 In one embodiment, a cleaning component is also included. The cleaning component includes a cleaning brush 40. A third mounting groove 3032 is provided at the bottom of the movable plate 303. The cleaning brush 40 is disposed in the third mounting groove 3032, and the brush part of the cleaning brush 40 can contact the filter screen 302.
[0048] In the above embodiment, by setting a cleaning brush 40, the rotation of the moving plate 303 can drive the cleaning brush 40 to rotate and contact the filter screen 302, thereby facilitating the cleaning of the filter screen 302 and making the cleaning of the filter screen 302 convenient.
[0049] Please see Figure 2 , Figures 4 to 7 In one embodiment, the cleaning assembly further includes a second transmission assembly; the cleaning brush 40 is slidably disposed in the third mounting groove 3032, the second transmission assembly is disposed on the moving plate 303 and connects the cleaning brush 40 and the cylinder 10, the second transmission assembly is used to convert the rotation of the moving plate 303 into the reciprocating up and down movement of the cleaning brush 40, so that the brush part of the cleaning brush 40 can pass through the filter screen 302. Specifically, the second transmission assembly includes a tension spring 402, a lever 403, and a wedge-shaped guide block 404; the top of the cleaning brush 40 is provided with a connecting shaft 401, which extends upward through the moving plate 303 and is connected to the lever 403; the tension spring 402 is sleeved on the connecting shaft 401, and its two ends are respectively connected to the lever 403 and the moving plate 303; an annular groove 107 is provided on the periphery of the storage cavity; multiple sets of wedge-shaped guide blocks 404 are spaced apart in the annular groove 107; one end of the lever 403 extends into the annular groove 107 and can move sequentially along the wedge surface of the multiple sets of wedge-shaped guide blocks 404.
[0050] In the above embodiment, the rotation of the movable plate 303 drives the toggle block 403 to rotate. The rotation of the toggle block 403 allows it to contact the wedge surface of the wedge-shaped guide block 404 and move along the wedge surface. The movement of the toggle block 403 along the wedge surface causes it to move upwards. This upward movement of the toggle block 403 drives the cleaning brush 40 to move upwards via the connecting shaft 401, and also puts tension on the tension spring 402. When the toggle block 403 moves and separates from the wedge-shaped guide block 404, the reaction force of the tension spring 402 causes the toggle block 403 to move downwards. This downward movement of the toggle block 403... The cleaning brush 40 is driven to move downward by the connecting shaft 401. This repeated movement drives the cleaning brush 40 to move up and down repeatedly. The up-and-down movement of the cleaning brush 40 allows the brush bristles to pass through the filter screen 302, making it easier to unclog the filter screen 302 and preventing it from becoming clogged. At the same time, when the cleaning brush 40 rotates to the top of the solid chamber 105, the up-and-down movement of the cleaning brush 40 can shake off the solid medical waste attached to the cleaning brush 40 into the solid chamber 105, which facilitates the self-cleaning of the cleaning brush 40.
[0051] The specific implementation method of the above-mentioned operating room nursing waste collection device is as follows:
[0052] When disposing of medical waste, the foot pedal 204 moves downward, compressing the spring 2041. This downward movement of the pedal 204, via the connecting rod 203, moves the rack 2031 downward, engaging with the transmission gear 2072 and causing it to rotate clockwise. The clockwise rotation of the transmission gear 2072, through the rotating shaft 207, drives the sector bevel gear 2071 to rotate clockwise. The clockwise rotation of the sector bevel gear 2071 engages with the second bevel gear 206, thus driving the support plate 202 to rotate. This causes the support plate 202 to seal the bottom of the temporary storage cavity 101. Once the support plate 202 seals the bottom of the temporary storage cavity 101, the sector bevel gear... As the sector bevel gear 2071 continues to rotate and separates from the second bevel gear 206, the support plate 202 stops rotating and remains sealed at the bottom of the temporary storage cavity 101. When the sector bevel gear 2071 continues to rotate and meshes with the first bevel gear 205, the rotation of the sector bevel gear 2071 drives the sealing plate 201 to rotate and open the top of the temporary storage cavity 101 through the first bevel gear 205. By first driving the support plate 202 to seal the bottom of the temporary storage cavity 101, bacteria in the storage cavity can be prevented from escaping when the sealing plate 201 opens the top of the temporary storage cavity 101. Then, medical waste is placed into the temporary storage cavity 101, at which time the support plate 202 carries the medical waste.
[0053] Then, the force applied to pedal 204 is removed. The reaction force of spring 2041 drives pedal 204 to move upward. The upward movement of pedal 204 drives connecting rod 203 and rack 2031 to move upward, driving transmission gear 2072 to rotate counterclockwise. The counterclockwise rotation of transmission gear 2072 drives sector bevel gear 2071 to rotate counterclockwise through rotating shaft 207. The counterclockwise rotation of sector bevel gear 2071 drives sealing plate 201 to rotate in the opposite direction through first bevel gear 205, sealing the top of temporary storage cavity 101. After sealing plate 201 seals the top of temporary storage cavity 101, sector bevel gear 2071 continues to rotate and interacts with first bevel gear 205. When wheel 205 separates, the sealing plate 201 stops rotating and remains in the sealed top position of the temporary storage cavity 101. When the sector bevel gear 2071 continues to rotate and meshes with the second bevel gear 206, the rotation of the sector bevel gear 2071 drives the bearing plate 202 to rotate in the opposite direction through the second bevel gear 206, opening the bottom of the temporary storage cavity 101. By first driving the sealing plate 201 to seal the top of the temporary storage cavity 101, it is possible to prevent bacteria in the storage cavity from escaping when the bearing plate 202 opens the bottom of the temporary storage cavity 101 and causes medical waste to fall onto the filter screen 302. This avoids the release of bacteria in the storage cavity during the disposal of medical waste and improves the safety of the device.
[0054] When medical waste falls onto filter 302, the liquid in the medical waste will fall into the liquid chamber 104 through filter 302, while the solid medical waste will remain above filter 302. Then, the controller 304 is activated to control the output shaft of motor 305 to rotate one revolution. One revolution of the output shaft of motor 305 drives the moving plate 303 to rotate one revolution through the transmission shaft 3031. The rotation of the moving plate 303 moves the solid medical waste on filter 302. When the solid medical waste comes into contact with the pressure plate 306, the rotation of the moving plate 303 and the cooperation of the pressure plate 306 can squeeze the solid medical waste, thereby removing the adsorbed substances from the solid medical waste. Liquid extrusion further improves the device's effect on solid-liquid separation of medical waste. When the force of the rotating plate 303 driving the solid medical waste to move is greater than the torque of the torsion spring 307, the movement of the solid medical waste drives the pressure plate 306 to rotate. At this time, the rotation of the moving plate 303 driving the solid medical waste to move allows the solid medical waste to fall into the solid chamber 105, making solid-liquid separation of medical waste convenient. After the solid medical waste falls into the solid chamber 105, the end of the moving plate 303 can contact the surface of the pressure plate 306. At this time, the rotation of the moving plate 303 can scrape off the solid medical waste attached to the pressure plate 306, making it easy to clean the pressure plate 306.
[0055] Simultaneously, the rotation of the movable plate 303 drives the rotating block 403 to rotate. The rotating block 403 contacts the wedge surface of the wedge-shaped guide block 404 and moves along the wedge surface. The movement of the block 403 along the wedge surface causes it to move upwards. This upward movement of the block 403 drives the cleaning brush 40 upwards via the connecting shaft 401, and also puts tension on the tension spring 402. When the block 403 moves and separates from the wedge-shaped guide block 404, the reaction force of the tension spring 402 causes the block 403 to move downwards. This downward movement of the block 403 allows the cleaning brush 40 to move upwards via the connecting shaft 401. The connecting shaft 401 drives the cleaning brush 40 to move downwards. Repeating this motion drives the cleaning brush 40 to move up and down repeatedly. The up-and-down movement of the cleaning brush 40 allows the brush bristles to pass through the filter screen 302, facilitating the unblocking of the filter screen 302 and preventing clogging. At the same time, when the cleaning brush 40 rotates to the top of the solid chamber 105, the up-and-down movement of the cleaning brush 40 shakes off the solid medical waste attached to the cleaning brush 40 into the solid chamber 105, facilitating the self-cleaning of the cleaning brush 40.
