Modes for Carrying Out the Invention

[0044] In order to enable those skilled in the art to better understand the solutions of the present invention, the following will provide a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0045] The present application is further described in detail below with reference to the accompanying drawings.

[0046] The embodiments of the present application disclose an embedded automatic disinfection negative pressure medical waste collection device and method.

[0047] As shown in Figures 1, 2 and 3, an embeddable automatic disinfection negative pressure collection device for medical waste includes: a mounting member 1, a negative pressure maintaining module 2 and a cover opening module 3. The mounting member 1 is nested on the mouth of the trash can, and a delivery through hole 114 is provided on the mounting member 1, and the delivery through hole 114 is provided corresponding to the mouth of the trash can; and an accommodating space is formed inside the mounting member 1; the negative pressure maintaining module 2 is provided in the accommodating space; the negative pressure maintaining module 2 extends into the delivery through hole 114, and is used to suck the air in the delivery through hole 114; the cover opening module 3 is rotatably provided on the mounting member 1, and the cover opening module 3 is used to cover the delivery through hole 114; wherein, a central control device is provided on the mounting member 1, the negative pressure maintaining module 2 is electrically connected to the central control device, and the cover opening module 3 is electrically connected to the central control device, and the central control device is used to receive the opening signal of the cover opening module 3 and control the suction power of the negative pressure maintaining module 2.

[0048] Put the garbage bag on the trash can and place the trash can under the mounting member 1 so that the insertion hole 114 corresponds to the opening of the trash can, so that the mounting member 1 can be embedded on the top of the trash can. After the mounting member 1 is installed, the medical waste negative pressure collection device is activated. Under normal circumstances, the cover module 3 is in a state covering the delivery hole 114. At this time, the negative pressure maintaining module 2 works to suck the gas in the trash can, so that a stable negative pressure environment is formed in the trash can. When medical waste needs to be delivered to the trash can, the cover module 3 is opened. At this time, to prevent the gas in the trash can from flowing out of the outside with the opening of the cover module 3, the central control device receives the signal of the cover module 3 opening and controls the negative pressure maintaining module 2 to increase the suction power. When the gas in the trash can flows to the position of the delivery hole 114, it can be sucked by the negative pressure maintaining module 2, effectively preventing the gas in the trash can from flowing out of the outside. The medical waste negative pressure collection device is separated from the trash can structure and is compatible with existing medical waste cans. The trash can only require a single-layer shell, and does not require a special inner and outer barrel two-layer design. It has high adaptability to trash cans and reduces manufacturing costs. When in use, it only needs to be nested above the trash can to achieve negative pressure suction of the trash can, solving the problem that existing trash cans on the market are not compatible with negative pressure devices.

[0049] As shown in Figures 3 and 4, the mounting member 1 includes a sealed shell 11 and a workbench 12. The sealed shell 11 is provided with a delivery hole 114, and an accommodating space is formed inside the sealed shell 11; the workbench 12 is arranged in the accommodating space and is arranged around the delivery hole 114.

[0050] Specifically, in this embodiment, the sealed housing 11 is rectangular in shape and includes an upper sealing plate 111, a lower sealing plate 112, and a sealing frame 113. The outer peripheral edge of the lower sealing plate 112 is fixedly connected to the upper sealing plate 111 through the sealing frame 113.

[0051] The through hole 114 is located at the center of the sealed housing 11. The through hole 114 faces the opening of the trash can and is smaller than or equal to the opening of the trash can. In this embodiment, the through hole 114 is circular.

[0052] The workbench 12 is fixed within the storage space. Its thickness is the same as that of the sealing frame 113, and its upper and lower surfaces can abut against the upper sealing plate 111 and the lower sealing plate 112, respectively. A communication hole 121 is located at the center of the workbench 12. The size of the communication hole 121 should be smaller than or equal to the size of the delivery hole 114. The communication hole 121 is concentrically arranged with the delivery hole 114, so that the workbench 12 is also located at the center of the sealed housing 11. The workbench 12 is bolted to the upper sealing plate 111 and the lower sealing plate 112, respectively, so that the workbench 12 is in a compressed and sealed state between the upper and lower sealing plates 111 and 112. The bolt holes on the workbench 12 are spaced around the communication hole 121, improving the stability of the workbench 12 within the storage space and effectively preventing gas within the trash can from entering the storage space through the gaps between the workbench 12 and the upper and lower sealing plates 111 and 112.

[0053] As shown in Figures 1, 3 and 6, the negative pressure maintaining module 2 includes a negative pressure fan 21, a negative pressure pipeline 22 and a negative pressure exhaust nozzle 23. One end of the negative pressure pipeline 22 is connected to the negative pressure fan 21, and the other end extends into the accommodating space and is arranged around the workbench 12. One end of the negative pressure exhaust nozzle 23 is connected to the negative pressure pipeline 22.

[0054] Specifically, the negative pressure fan 21 is used to provide the power for exhaust, and the negative pressure fan 21 is arranged outside the mounting member 1. The negative pressure fan 21 is electrically connected to the central control device, which can control the speed of the negative pressure fan 21 to achieve the control of the exhaust power of the negative pressure maintaining module 2.

[0055] The negative pressure pipeline 22 includes a main negative pressure pipeline 221, a secondary negative pressure pipeline 222, and a negative pressure manifold 223. The negative pressure manifold 223 can connect multiple pipelines and allow multiple pipelines to communicate within the negative pressure manifold 223. The main negative pressure pipeline 221 is connected to the negative pressure blower 21 at one end and to the negative pressure manifold 223 at the other end. The negative pressure manifold 223 is also connected to multiple secondary negative pressure pipelines 222. The multiple secondary negative pressure pipelines 222 extend into the accommodating space and are arranged around the workbench 12. A negative pressure exhaust nozzle 23 is provided at the end of the secondary negative pressure pipeline 222.

[0056] The negative pressure branching piece 223 is also arranged on each auxiliary negative pressure pipeline 222, and the negative pressure branching piece 223 arranged on each auxiliary negative pressure pipeline 222 is also connected to a negative pressure exhaust nozzle 23, so that multiple negative pressure exhaust nozzles 23 can be set on one auxiliary negative pressure pipeline 222, thereby improving the overall exhaust power.

[0057] In this embodiment, there is one main negative pressure line 221 and two auxiliary negative pressure lines 222, namely a first auxiliary negative pressure line and a second auxiliary negative pressure line. Three negative pressure manifolds 223 are provided, namely a first negative pressure manifold, a second negative pressure manifold, and a third negative pressure manifold. The first negative pressure manifold is provided below the mounting member 1, and the main negative pressure line 221, the first auxiliary negative pressure line, and the second auxiliary negative pressure line are all connected to the first negative pressure manifold. The first auxiliary negative pressure line and the second auxiliary negative pressure line respectively enter the accommodating space from both ends of one side of the mounting member 1, and the first auxiliary negative pressure line and the second auxiliary negative pressure line are respectively provided on opposite sides of the workbench 12 in the accommodating space. The negative pressure exhaust nozzle 23 at the end of the first auxiliary negative pressure line is the first negative pressure exhaust nozzle, and the negative pressure exhaust nozzle 23 at the end of the second auxiliary negative pressure line is the second negative pressure exhaust nozzle. The second and third negative pressure manifolds are respectively disposed on the first and second auxiliary negative pressure pipelines. Both the second and third negative pressure manifolds are fixedly connected to the lower sealing plate 112. The negative pressure exhaust nozzle 23 on the second negative pressure manifold is the third negative pressure exhaust nozzle, and the negative pressure exhaust nozzle 23 on the third negative pressure manifold is the fourth negative pressure exhaust nozzle. The first, second, third, and fourth negative pressure exhaust nozzles are spaced apart around the workbench 12.

[0058] The negative pressure maintaining module 2 also includes a filter device 24 and an exhaust pipe 25. The filter system is connected to the negative pressure blower 21 through the exhaust pipe 25. The filter device 24 is located below the mounting member 1 and can perform harmless treatment on the gas extracted from the trash can.

[0059] Of course, the negative pressure fan 21 can also be directly connected to the hospital's dedicated channel to achieve harmless treatment of the gas extracted from the garbage bin.

[0060] As shown in Figures 1, 4, 5 and 6, first negative pressure vent holes 122 connecting the accommodating space and the delivery through hole 114 are arranged at intervals on the workbench 12; the negative pressure maintaining module 2 is inserted into the first negative pressure vent hole 122 for drawing air toward the delivery through hole 114.

[0061] Specifically, a plurality of first negative-pressure vent holes 122 are provided, and are disposed on the sidewall of the workpiece. The first negative-pressure vent holes 122 are disposed at positions corresponding to the negative-pressure exhaust nozzles 23, and the other end of the negative-pressure exhaust nozzles 23 are connected to the first negative-pressure vent holes 122. The negative-pressure exhaust nozzles 23 can draw gas from the first negative-pressure vent holes 122. The negative-pressure exhaust nozzles 23 are threadedly connected to the first negative-pressure vent holes 122, and a nut is further provided at the portion of the negative-pressure exhaust nozzles 23 located within the accommodating space. When the negative-pressure exhaust nozzles 23 are threadedly connected to the first negative-pressure vent holes 122, the nut can abut against the sidewall of the workbench 12, thereby improving the airtightness of the negative-pressure exhaust nozzles 23 after they are attached to the first negative-pressure vent holes 122, and effectively preventing gas within the trash can from entering the accommodating space through the gap at the connection between the negative-pressure exhaust nozzles 23 and the first negative-pressure vent holes 122.

[0062] In this embodiment, four first negative pressure vent holes 122 are provided, and the four first negative pressure vent holes 122 are arranged at the same height on the workbench 12, and the first negative pressure exhaust nozzle, the second negative pressure exhaust nozzle, the third negative pressure exhaust nozzle and the fourth negative pressure exhaust nozzle are respectively inserted into the corresponding first negative pressure vent holes 122.

[0063] A second negative pressure vent hole 123 is further provided on the workbench 12 . One end of the second negative pressure vent hole 123 is connected to the delivery through hole 114 , and the other end is connected to the first negative pressure vent hole 122 .

[0064] Specifically, the end of the negative pressure exhaust nozzle 23 does not protrude from the first negative pressure vent hole 122, but is located inside the first negative pressure vent hole 122. A ventilation channel is provided in the first negative pressure vent hole 122, and the ventilation channel is provided in front of the negative pressure exhaust nozzle 23. The second negative pressure vent hole 123 is connected to the ventilation channel, and the second negative pressure vent hole 123 is not connected to the accommodating space. In this way, when the negative pressure exhaust nozzle 23 is in operation, it can not only suck the air in the trash can through the first negative pressure vent hole 122, but also connect the first negative pressure vent hole 122 and the second negative pressure vent hole 123 through the ventilation channel, so that they can jointly suck the air in the trash can, forming a negative pressure air curtain, and ensuring that the air in the trash can does not overflow.

[0065] In this embodiment, a plurality of second negative pressure vent holes 123 are arranged at intervals on both sides of each first negative pressure vent hole 122 , wherein the aperture size of the second negative pressure vent holes 123 is smaller than the aperture size of the first negative pressure vent holes 122 .

[0066] The negative pressure maintaining module 2 also includes a negative pressure sensor, which is arranged on the inner wall of the connecting hole 121 and is electrically connected to the central control device. The negative pressure sensor can sense the negative pressure state in the trash can and transmit the signal to the central control device in real time for processing.

[0067] When the opening cover module 3 covers the delivery hole 114, the negative pressure maintaining module 2 works at the first suction power, and the negative pressure fan 21 runs at the first speed, so that the negative pressure suction nozzle 23 maintains the first suction power to exhaust the gas in the trash can through the first negative pressure vent 122 and the second negative pressure vent 123, thereby forming a negative pressure environment in the cavity formed between the trash can and the mounting part 1. The negative pressure environment at this time is the first negative pressure state.

[0068] When the cover opening module 3 is opened to dump medical waste into the trash can, the central control device receives the cover opening signal transmitted by the cover opening module 3. In order to prevent the gas in the trash can from escaping to the outside, it is necessary to control the negative pressure fan 21 to increase the speed and run at the second speed, so that the negative pressure exhaust nozzle 23 exhausts the gas in the trash can through the first negative pressure vent 122 and the second negative pressure vent 123 with the second exhaust power.

[0069] When the medical waste is dumped and the cover module 3 is re-covered on the delivery hole 114, the negative pressure exhaust nozzle 23 continues to exhaust the gas in the trash can through the first negative pressure vent 122 and the second negative pressure vent 123 at the second exhaust power until the negative pressure sensor detects that the negative pressure environment has returned to the first negative pressure state. The negative pressure sensor transmits a signal to the central control device, which controls the negative pressure fan 21 to reduce its speed and return to the first speed. The first exhaust power is less than the second exhaust power.

[0070] As shown in Figures 1, 3, 8, 9 and 10, the opening module 3 includes a rotating cover plate 31 and a rotating hinge 32. The rotating cover plate 31 covers the injection hole 114; the rotating hinge 32 is arranged on the top of the mounting member 1, and the rotating cover plate 31 is hinged to the mounting member 1 through the rotating hinge 32.

[0071] Specifically, the rotating cover 31 is disposed near the delivery hole 114, and the rotating hinge 32 is detachably connected to the rotating cover 31 and the upper sealing plate 111 by threads. When the rotating cover 31 is flipped over so that the rotating cover 31 covers the delivery hole 114, the rotating cover 31 can completely cover the delivery hole 114.

[0072] The cover opening module 3 also includes a push rod assembly 34 and a cover plate connector 36. The push rod assembly 34 is arranged on the inner surface of the top of the mounting member 1 of the sealed shell 11. The push rod assembly 34 is rotatably connected to the cover plate connector 36, and the cover plate connector 36 is fixedly connected to the rotating cover plate 31.

[0073] Specifically, the push rod assembly 34 includes a push rod fixing member 341, an electric push rod 342, and a connecting rod 343. The push rod fixing member 341 is fixed to a side of the upper sealing plate 111 located in the accommodating space. The electric push rod 342 is pressed against the lower surface of the upper sealing plate 111 by the push rod fixing member 341. The electric push rod 342 is electrically connected to the central control device. The electric push rod 342 includes a push rod housing 3421 and an output rod 3422. The push rod housing 3421 is pressed, and the output rod 3422 is slidably set in the push rod housing 3421. The output rod 3422 can perform telescopic movement in the push rod housing 3421 under the control of the central control device. The end of the output rod 3422 away from the push rod housing 3421 is rotatably connected to one end of the connecting rod 343, and the other end of the connecting rod 343 is rotatably connected to the cover plate connector 36.

[0074] The cover plate connector 36 includes a push rod connecting portion 361 and a fixed portion 362. The push rod connecting portion 361 and the fixed portion 362 are integrally formed, and the push rod connecting portion 361 and the fixed portion 362 are arranged perpendicularly. The push rod connecting portion 361 is located within the accommodating space and is rotatably connected to the connecting rod 343. Part of the fixed portion 362 passes through the upper sealing plate 111 and is bolted to the rotating cover plate 31. The upper sealing plate 111 is provided with a flip hole 1111 for the fixed portion 362 to pass through at the position where the fixed portion 362 passes through. The size of the flip hole 1111 is larger than the cross-sectional area of ​​the fixed portion 362, and the flip hole 1111 reserves a folding space for the fixed portion 362 to rotate.

[0075] In this embodiment, two sets of push rod assemblies 34 and cover plate connectors 36 are provided on both sides of the rotating cover plate 31 , and the two push rod assemblies 34 are both provided close to the workbench 12 .

[0076] When it is necessary to open the rotating cover 31 to dump medical waste into the trash can, the central control device sends a signal to the electric push rod 342. After the electric push rod 342 receives the command, the output rod 3422 retracts close to the push rod housing 3421. Through the transmission of force, the cover connector 36 rotates under the action of the force, thereby causing the rotating cover 31 to rotate and close.

[0077] When the rotating cover 31 needs to be closed, the central control device sends a signal to the electric push rod 342. After the electric push rod 342 receives the command, the output rod 3422 extends away from the push rod housing 3421. Through the transmission of force, the cover connector 36 rotates in the opposite direction under the action of the inner force, thereby causing the rotating cover 31 to rotate open.

[0078] The cover opening module 3 also includes a human body sensing sensor 33, which is arranged on the mounting part 1. The human body sensing sensor 33 is used to control the movement of the push rod assembly 34. The human body sensing sensor 33 is electrically connected to the central control device. The human body sensing sensor 33 is used to collect information on whether someone is approaching the medical waste negative pressure collection device and is preparing to throw medical waste.

[0079] Specifically, the human body sensing sensor 33 includes one of an infrared sensor, a PCR radar sensor, and a Doppler microwave sensor. The human body sensing sensor 33 can sense the surrounding environment in real time and determine whether a human body is approaching the medical waste negative pressure collection device. In this embodiment, the human body sensing sensor 33 is disposed within the accommodating space. The human body sensing sensor 33 is located on the side opposite to the installation position of the rotating cover 31. The human body sensing sensor 33 is fixed to the sealing frame 113. A sensing hole 1112 is provided on the upper sealing plate 111. The sensing hole 1112 is located directly above the human body sensing sensor 33. The human body sensing sensor 33 can pass through the sensing hole 1112 to detect the upper front position of the medical waste negative pressure collection device.

[0080] Normally, the rotating cover 31 is in a state of covering the injection hole 114 .

[0081] When the human body sensing sensor 33 detects that someone is approaching, the human body sensing sensor 33 transmits the signal to the central control device. After processing, the central control device issues a command to the electric push rod 342. After the electric push rod 342 receives the command, the output rod 3422 retracts close to the push rod housing 3421, and the rotating cover 31 is opened to dump medical waste into the trash can.

[0082] When the human body sensing sensor 33 detects that there is no one, the human body sensing sensor 33 transmits the signal to the central control device. After processing, the central control device issues a command to the electric push rod 342. After the electric push rod 342 receives the command, the output rod 3422 extends away from the push rod housing 3421 to close the rotating cover 31.

[0083] As shown in Figures 1, 3, 4 and 7, the negative pressure collection device for medical waste also includes a disinfectant container 41, a disinfection pipeline 42 and a disinfection nozzle 43. One end of the disinfection pipeline 42 is connected to the disinfectant container 41, and the other end extends into the accommodating space and docks with the disinfection nozzle 43; wherein, a disinfection through hole 124 connecting the accommodating space and the delivery through hole 114 is provided on the workbench 12, and the disinfection nozzle 43 is arranged in the disinfection through hole 124.

[0084] Specifically, the disinfectant container 41 is disposed outside the mounting member 1 and below the mounting member 1. The disinfection line 42 includes a main disinfection line 421, a disinfection branch line 422, and a disinfectant pump 423. One end of the main disinfection line 421 is connected to the disinfectant container 41, and the other end is connected to the disinfection branch line 422. The disinfection nozzle 43 is arranged on the pipe mouth of the disinfection branch pipe 422. One or more disinfection branch pipes 422 can be set. The disinfection branch pipes 422 are arranged around the workbench 12. The disinfection nozzle 43 passes through the disinfection through hole 124 and is exposed from the side wall of the connecting hole 121. The disinfectant stored in the disinfectant container 41 can pass through the main disinfection pipe 421 and the disinfection branch pipe 422 in turn and finally be sprayed out from the disinfection nozzle 43. The disinfection nozzle 43 is a low-pressure atomizing nozzle. The disinfectant is sprayed from the side wall of the connecting hole 121 to form a mist distribution in the space of the connecting hole 121, and will fall into the trash can below under the action of gravity, thereby disinfecting the medical waste in the garbage bag in the trash can, thereby improving the safety of storing medical waste.

[0085] In this embodiment, two disinfection branch pipes 422 are provided, and the disinfection nozzles 43 on the two disinfection branch pipes 422 are arranged opposite to each other on the workbench 12, thereby expanding the disinfection range so as to more comprehensively disinfect the medical waste in the garbage belt.

[0086] The medical waste negative pressure collection device also includes a liquid level sensor 44 and a control valve 45. The liquid level sensor 44 is arranged on the disinfectant container 41 and is used to collect the liquid level signal in the disinfectant container. The control valve 45 is arranged on the disinfection pipeline 42 and is used to control the on and off of the disinfection pipeline.

[0087] Specifically, the liquid level sensor 44 is electrically connected to the central control device. The liquid level sensor 44 can collect the liquid level information in the disinfectant container 41 in real time. When the liquid level in the disinfectant container 41 is lower than the position of the liquid level sensor 44, the liquid level sensor 44 will send a signal to the central control device.

[0088] The control valve 45 is provided at the connection between the main disinfection pipeline 421 and the disinfection branch pipeline 422. The control valve 45 can control the on-off of the connection between the main disinfection pipeline 421 and the disinfection branch pipeline 422. The control valve 45 is electrically connected to the central control device, and the opening or closing of the control valve 45 is controlled by the central control device.

[0089] The liquid level sensor 44 is arranged on the outside of the disinfectant container 41 near the bottom. When there is no disinfectant in the disinfectant container 41 or the amount of disinfectant is insufficient, the disinfection module 4 automatically stops disinfecting the trash can and sends an alarm signal to the central control device, prompting the replacement of the disinfectant, thereby avoiding damage to the disinfectant pump 423.

[0090] The central control unit is equipped with a timing program that controls control valve 45, intermittently opening and closing it, enabling disinfection module 4 to release a fixed amount of disinfectant at regular intervals. Control valve 45 is normally closed. At regular intervals, the central control unit sends a signal to control valve 45, opening it for a specific period, allowing disinfection nozzle 43 to spray disinfectant into the trash can. Control valve 45 then opens again, and after a certain period, opens again to spray disinfectant into the trash can. For example, every ten minutes, the central control unit opens control valve 45 for one second, then opens it again for another ten minutes, and then opens it again for one second, repeating this cycle (not limited to ten minutes or one second). This intermittent opening and closing of control valve 45 allows for the timely and fixed release of disinfectant, effectively conserving disinfectant, avoiding the waste of disinfectant that would otherwise be wasted by continuously spraying it into the trash can, and preventing disinfectant in the pipeline from seeping into the trash can.

[0091] Here, the disinfectant container 41 , the disinfection pipeline 42 , the disinfection nozzle 43 , the liquid level sensor 44 and the control valve 45 are collectively referred to as the disinfection module 4 .

[0092] The disinfection module 4 can also cooperate with the lid opening module 3. That is, when the human body sensing sensor 33 detects that someone is approaching and sends a signal to the central control device, the central control device will send a signal to the lid opening module 3 to open the rotating cover 31, and at the same time, it will command the control valve 45 to be turned on for a preset time to disinfect the trash can.

[0093] Among them, the priority of the above-mentioned two central control devices to command the control valve 45 to be turned on or off is lower than the priority of the liquid level sensor 44 feedback and commanding the control valve 45 to be closed, that is, regardless of whether the scheduled time for releasing the disinfectant has arrived or the control valve 45 needs to be turned on when the lid is opened, as long as the liquid level in the disinfectant container 41 is lower than the position of the liquid level sensor 44, the control valve 45 is in the disconnected state.

[0094] As shown in FIG1 , FIG3 and FIG11 , the negative pressure collection device for medical waste further includes a sealing module 5 , which is disposed below the mounting member 1 and abuts against the opening of the trash can.

[0095] Specifically, the sealing module 5 includes an annular airbag 51, a pressure relief control valve 52, an air pump 53, and an air charging line 54. The annular airbag 51 is positioned on the lower surface of the lower sealing plate 112 and surrounds the delivery hole 114. Existing medical waste bins typically have rectangular openings with a raised ridge around the edges.

[0096] In this embodiment, the shape of the annular airbag 51 is a rectangle that matches the ridges on the mouth of an existing medical waste bin.

[0097] One end of the inflation line 54 is connected to the inflation pump 53, and the other end is connected to the annular airbag 51. The inflation pump 53 can inflate the annular airbag 51 through the inflation line 54, causing the annular airbag 51 to expand. A pressure relief control valve 52 is also connected to the annular airbag 51 and is used to discharge the gas in the annular airbag 51, facilitating the disconnection of the medical waste negative pressure collection device from the trash can.

[0098] An air inlet pipe joint 511 and an air outlet pipe joint 512 are also installed on the annular airbag 51 . The air inlet pipe joint 511 is connected to the inflation pipeline 54 and the annular airbag 51 , and the air outlet pipe joint 512 is connected to the pressure relief control valve 52 and the annular airbag 51 .

[0099] In addition, an air intake valve core can be provided in the air intake pipe joint 511 . The air intake valve core has unidirectional conductivity and controls the gas to flow into the annular airbag 51 in one direction through the inflation pump 53 .

[0100] The trash can is placed under the mounting member 1 so that its opening faces the through hole 114. The annular airbag 51 on the lower sealing plate 112 adheres to the surface of the trash can's opening with its ridges surrounding the opening. The airbag 51 is inflated by the air pump 53. The airbag 51 expands inward and outward, clamping onto the ridges around the edge of the trash can's opening. Since a trash bag is placed inside the trash can and is about to be turned outward from the opening, the bag is pressed against the trash can by the airbag 51, forming a seal.

[0101] The provision of the sealing module 5 not only enhances the stability of the embedded fit between the mounting member 1 and the trash can, but also forms a seal at the fitting location, effectively preventing the gas generated in the trash can from flowing out through the gap between the mounting member 1 and the trash can.

[0102] In addition, the present invention can also realize the classified collection of various medical wastes, and set up multiple sets of medical waste negative pressure collection devices. The negative pressure maintaining modules 2 and disinfection modules 4 of the multiple sets of medical waste negative pressure collection devices can be connected and used. A universal medical waste bin can be placed below to quickly realize multiple sets of arrangements.

[0103] For example, as shown in Figures 1, 6, 7, and 12, two medical waste negative pressure collection devices are provided. These two devices have identical structures, except that the negative pressure maintenance module 2 of one of these devices no longer includes the negative pressure blower 21 and the main negative pressure pipeline 221, and the disinfection module 4 no longer includes the liquid level sensor 44, disinfectant container 41, and main disinfection pipeline 421. The two medical waste negative pressure collection devices are connected via a disinfection branch pipeline 422 and a secondary negative pressure pipeline 222. The secondary negative pressure pipeline 222 is connected to the negative pressure branching members 223 on each of the two medical waste negative pressure collection devices, and the disinfection branch pipeline 422 is connected to the control valves 45 on each of the two medical waste negative pressure collection devices. This allows the negative pressure blower 21 and disinfectant container 41 to simultaneously provide a negative pressure environment and disinfect the corresponding waste bins of both medical waste negative pressure collection devices.

[0104] As shown in FIG13 , the present invention further discloses a method for an embedded automatic disinfection medical waste negative pressure collection device as described above, which comprises the steps of:

[0105] S100 , extracting gas from the delivery through hole with a first pumping power through a negative pressure maintaining module to maintain a negative pressure environment in the delivery through hole.

[0106] S200: When a lid opening signal is received, control the negative pressure maintaining module to pump air at a second pumping power; wherein the second pumping power is greater than the first pumping power. The adjustment method disclosed in this embodiment enables the central control device to promptly respond to and adjust the negative pressure state within the trash can, effectively preventing gas within the trash can from escaping to the outside world and resolving the issue of existing trash cans on the market being incompatible with negative pressure devices.

[0107] To sum up, an embeddable automatic disinfection negative pressure collection device for medical waste includes: a mounting part 1, a negative pressure maintaining module 2 and a cover opening module 3, the mounting part 1 is nested on the mouth of the trash can, and a delivery through hole 114 is provided on the mounting part 1, and the delivery through hole 114 is provided corresponding to the mouth of the trash can; and a accommodating space is formed inside the mounting part 1; the negative pressure maintaining module 2 is arranged in the accommodating space; the negative pressure maintaining module 2 extends into the delivery through hole 114, and is used to suck the air in the delivery through hole 114; the cover opening module 3 is rotatably arranged on the mounting part 1, and the cover opening module 3 is used to cover the delivery through hole 114; wherein, a central control device is provided on the mounting part 1, the negative pressure maintaining module 2 is electrically connected to the central control device, and the cover opening module 3 is electrically connected to the central control device, and the central control device is used to receive the opening signal of the cover opening module 3 and control the suction power of the negative pressure maintaining module 2.

[0108] Put the garbage bag on the trash can and place the trash can under the mounting member 1 so that the insertion hole 114 corresponds to the opening of the trash can, so that the mounting member 1 can be embedded on the top of the trash can. After the mounting member 1 is installed, the medical waste negative pressure collection device is activated. Under normal circumstances, the cover module 3 is in a state covering the delivery hole 114. At this time, the negative pressure maintaining module 2 works to suck the gas in the trash can, so that a stable negative pressure environment is formed in the trash can. When medical waste needs to be delivered to the trash can, the cover module 3 is opened. At this time, to prevent the gas in the trash can from flowing out of the outside with the opening of the cover module 3, the central control device receives the signal of the cover module 3 opening and controls the negative pressure maintaining module 2 to increase the suction power. When the gas in the trash can flows to the position of the delivery hole 114, it can be sucked by the negative pressure maintaining module 2, effectively preventing the gas in the trash can from flowing out of the outside. The medical waste negative pressure collection device is separated from the trash can structure and is compatible with existing medical waste cans. The trash can only require a single-layer shell, and does not require a special inner and outer barrel two-layer design. It has high adaptability to trash cans and reduces manufacturing costs. When in use, it only needs to be nested above the trash can to achieve negative pressure suction of the trash can, solving the problem that existing trash cans on the market are not compatible with negative pressure devices.

[0109] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.
