Description

Technical Field

[0001] The invention relates to the field of medical technology, and in particular to an outdoor medical waste collection device. Background Art

[0002] In outdoor emergency medical situations, due to the limitations of on-site conditions, patients cannot be immediately transferred to a more suitable treatment environment, and medical staff need to clean and bandage the wounds on site. In this process, proper disposal of medical waste is crucial to prevent environmental pollution and secondary infection. Special collection devices are required to recycle medical waste. However, since medical waste contains a large amount of flexible items such as gauze, cotton, and paper towels, they tend to expand and occupy most of the space in the collection device, resulting in reduced space utilization.

[0003] The existing medical waste collection box has a technical problem of reduced space utilization due to the difficulty in adapting to the easy expansion characteristics of flexible waste. Summary of the invention

[0004] The object of the present invention is to provide an outdoor medical waste collection device to solve the technical problem in the related art that the space utilization rate is reduced due to the difficulty in adapting to the easy expansion characteristics of flexible waste.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] The outdoor medical waste collection device provided by the present invention comprises:

[0007] A box unit, a feeding unit and a compression unit. The box unit includes a main box, and the feeding unit is installed on the main box. The compression unit includes a first compression assembly and a second compression assembly, the first compression assembly is installed on the feeding unit, and the second compression assembly is installed on the main box. The first compression assembly and the second compression assembly move toward each other to compress the waste in the feeding unit, and then transfer the waste to the storage space of the main box.

[0008] Specifically, the main housing is provided with a collecting hopper, and the collecting hopper is provided with a slide slot hole. The feeding unit includes a sliding draw tube and a pull plate, and the sliding draw tube is slidably connected to the slide slot hole. The sliding draw tube is provided with a compression chamber and a circumferential opening connected to the compression chamber. The pull plate is installed on the sliding draw tube, and is used to drive the sliding draw tube to slide so that the feeding unit is switched from a first state to a second state. In the first state, the circumferential opening is separated from the collecting hopper. In the second state, the circumferential opening is connected to the collecting hopper, and waste enters the compression chamber through the circumferential opening.

[0009] Specifically, the first compression assembly includes a sliding pressure plate, a pneumatic actuator and a thrust pump. The sliding pressure plate is slidably connected to the sliding pump cylinder. The pneumatic actuator is connected to the sliding pressure plate. The thrust pump is used to drive the pneumatic actuator to drive the sliding pressure plate to slide. The sliding pump cylinder is also provided with a bottom opening connected to the compression chamber. In the first state, the circumferential opening is separated from the collecting hopper, and the second compression assembly blocks the bottom opening. The sliding pressure plate slides toward the second compression assembly to reduce the volume of the compression chamber, thereby compressing the waste in the compression chamber.

[0010] Specifically, the second compression assembly includes an adsorption pump and a rotating motor, the rotating motor is installed at the bottom of the adsorption pump, and the adsorption pump is installed at the output end of the rotating motor. In the first state, the circumferential opening is separated from the collecting hopper, and the adsorption pump blocks the bottom opening. The negative pressure generated by the adsorption pump is used to apply suction to the waste material so as to suck the waste material into the compression chamber and adsorb it to the adsorption pump. The sliding pressure plate slides toward the adsorption pump to reduce the volume of the compression chamber, thereby compressing the waste material in the compression chamber. In the second state, the bottom opening is open, and the compression chamber is connected to the storage space of the main box body through the bottom opening. The airflow blown out by the adsorption pump is used to apply thrust to the waste material so that the waste material is separated from the adsorption pump, and the rotating motor drives the adsorption pump to rotate and throws the compressed waste material into the storage space of the main box body through centrifugal force.

[0011] Specifically, the compression unit further includes a limit assembly, which includes a control ring seat and a sliding plate. The second compression assembly further includes an axial sleeve, which is sleeved on the adsorption pump and the rotating motor and inserted into the main housing. The control ring seat is coaxially arranged with the bottom opening and installed on the sliding pump cylinder. One end of the sliding plate is clamped in the circumferential opening, and the other end is threadedly connected to the control ring seat. In the first state, the circumferential opening is separated from the collecting hopper, and the adsorption pump is inserted into the control ring seat and blocks the bottom opening; the abutment between the control ring seat and the axial sleeve is used to achieve axial limiting. In the second state, the abutment between the sliding plate and the collecting hopper is used to achieve axial limiting.

[0012] Specifically, the limit assembly further includes a rotating baffle, an isolation spring belt and a traction element. The rotating baffle is hinged to the sliding plate and extends into the compression chamber through the circumferential opening. The isolation spring belt is installed on the sliding plate to prevent waste from getting stuck in the hinge between the rotating baffle and the sliding plate. The traction element is installed on the sliding plate and connected to the rotating baffle, and can drive the rotating baffle to block the diameter of the compression chamber and limit the sliding range of the sliding pressure plate through the contact between the rotating baffle and the sliding pressure plate.

The rotary pulley is installed on the non-return nozzle, and the control rotary wheel is rotatably connected to the rotary pulley to drive the non-return nozzle to slide along the slide rail.

[0014] Specifically, the non-return nozzle includes a sliding sleeve, the piston nozzle and a spring ring. The inner wall of the sliding sleeve is provided with an annular groove, and the side wall of the piston nozzle is provided with an oblique nozzle. The sliding sleeve is slidably connected to the slide rail, the piston nozzle is slidably connected to the annular groove, and the spring ring is installed in the annular groove. The spring ring is used to drive the piston to slide along the annular groove, so that the sliding sleeve blocks the oblique nozzle. The pressure of the disinfectant pumped out by the suction pump overcomes the elastic force of the spring ring and pushes the piston nozzle to temporarily open the oblique nozzle.

[0015] Specifically, the feeding unit further comprises a pressing cylinder sleeved on the sliding cylinder, the pressing cylinder is configured as an elastic member, and the two ends of the pressing cylinder are respectively in contact with the sliding cylinder and the collecting hopper. The pressing cylinder is used to apply a thrust to the sliding cylinder to switch the feeding unit from the second state to the first state.

[0016] Specifically, the box unit further includes a side drawer box assembly, which includes a sliding box and a spring rod. The sliding box is slidably connected to the main box body and is used to store compressed waste. The two ends of the spring rod are respectively abutted against the main box body and the sliding box, and are used to apply a thrust to the sliding box to drive the sliding box to slide and retract into the main box body.

[0017] Based on the above technical solutions, the beneficial effects of the present invention are analyzed as follows:

[0018] The present invention provides an outdoor medical waste collection device, comprising:

[0019] A box unit, a feeding unit and a compression unit. The box unit includes a main box, and the feeding unit is installed on the main box. The compression unit includes a first compression assembly and a second compression assembly, the first compression assembly is installed on the feeding unit, and the second compression assembly is installed on the main box. The first compression assembly and the second compression assembly move toward each other to compress the waste in the feeding unit, and then transfer the waste to the storage space of the main box.

[0020] In specific application, the medical waste generated during the cleaning process is put into the outdoor medical waste collection device.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the units of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0049] The existing medical waste collection box has a technical problem of reduced space utilization due to the difficulty in adapting to the easy expansion characteristics of flexible waste.

[0050] In view of this, the present invention provides an outdoor medical waste collection device, comprising:

[0051] The box unit 100, the feeding unit 200 and the compression unit 300. The box unit 100 includes a main box 110, and the feeding unit 200 is installed on the main box 110. The compression unit 300 includes a first compression assembly 310 and a second compression assembly 320, the first compression assembly 310 is installed on the feeding unit 200, and the second compression assembly 320 is installed on the main box 110. The first compression assembly 310 and the second compression assembly 320 move toward each other to compress the waste in the feeding unit 200, and then transfer the waste to the accommodation space of the main box 110.

[0052] Based on the above technical solutions, the outdoor medical waste collection device provided by the present invention achieves the following technical effects:

[0053] The outdoor medical waste collection device is provided with a feeding unit 200 and the cooperation between the first compression assembly 310 and the second compression assembly 320. The flexible waste generated by medical treatment first enters the feeding unit 200 for compression operation and then is transferred to the main box 110, thereby reducing the occupation of the internal space by the waste. The technical problem of the existing medical waste collection box that the space utilization rate is reduced due to the difficulty in adapting to the easy expansion characteristics of the flexible waste is overcome.

[0054] The following combination Figures 1 to 18 The structure and shape of the outdoor medical waste collection device provided in this embodiment are described in detail:

[0055] Regarding the structural composition of the cabinet unit 100, specifically:

[0056] The box unit 100 also includes a side drawer box assembly 120, which includes a sliding box 121 and a spring rod 122. The sliding box 121 is slidably connected to the main box 110 and is used to store compressed waste. The two ends of the spring rod 122 are respectively abutted against the main box 110 and the sliding box 121, which is used to apply a thrust to the sliding box 121 to drive the sliding box 121 to slide and retract into the main box 110. The sliding box 121 is provided with a handle 1211, which is used to overcome the elastic force of the spring rod 122 to pull the sliding box 121 to open the internal space of the sliding box 121. Among them, the main box 110 is set to a transparent material.

[0057] How the waste enters the feeding unit 200 is as follows:

[0058] In the scheme of this embodiment, the main box body 110 is provided with a collecting hopper 111, and the collecting hopper 111 is provided with a chute hole. The feeding unit 200 includes a sliding pumping cylinder 210 and a pull plate 220, and the sliding pumping cylinder 210 is slidably connected to the chute hole. The sliding pumping cylinder 210 is provided with a compression chamber 201 and a circumferential opening 202 connected to the compression chamber 201. The pull plate 220 is installed on the sliding pumping cylinder 210, and the pull plate 220 is provided with a lifting handle 221, which is used to drive the sliding pumping cylinder 210 to slide so that the feeding unit 200 is switched from the first state to the second state. In the first state, the circumferential opening 202 is separated from the collecting hopper 111. In the second state, the circumferential opening 202 is connected with the collecting hopper 111, and the waste enters the compression chamber 201 through the circumferential opening 202. After releasing the lifting handle 221, under the action of gravity, the sliding pumping cylinder 210 moves downward to switch the feeding unit 200 from the second state to the first state, thereby closing the circumferential opening 202.

[0059] In order to prevent the waste materials inside the box unit 100 from generating toxic and smelly gases that leak to the outside and thus cause adverse effects on the medical environment, in the solution of this embodiment, the feeding unit 200 also includes a pressing cylinder 230 sleeved on the sliding pumping cylinder 210, and the pressing cylinder 230 is configured as an elastic member, and the two ends of the pressing cylinder 230 are respectively in contact with the sliding pumping cylinder 210 and the collecting hopper 111. The elastic force of the pressing cylinder 230 is used to apply a thrust to the sliding pumping cylinder 210 to switch the feeding unit 200 from the second state to the first state. At the same time, the pressing cylinder 230 further enhances the sealing of the box unit 100 by wrapping the sliding pumping cylinder 210.

[0060] Regarding the structural composition of the first compression assembly 310, specifically:

[0061] In the scheme of this embodiment, the first compression assembly 310 includes a sliding pressure plate 311, a pneumatic actuator 312 and a thrust pump 313. The sliding pressure plate 311 is slidably connected to the sliding pump 210, the pneumatic actuator 312 is connected to the sliding pressure plate 311, and the thrust pump 313 is used to drive the pneumatic actuator 312 to drive the sliding pressure plate 311 to slide. The sliding pump 210 is also provided with a bottom opening 203 connected to the compression chamber 201. In the first state, the circumferential opening 202 is separated from the collecting hopper 111, and the second compression assembly 320 blocks the bottom opening 203. The sliding pressure plate 311 slides toward the second compression assembly 320 to reduce the volume of the compression chamber 201, thereby compressing the waste in the compression chamber 201. Among them, the sliding pump 210 is also provided with a through hole 204, and the through hole 204 serves as an air inlet of the thrust pump 313.

[0062] In an optional solution of this embodiment, the pneumatic actuator 312 is configured as a pneumatic expansion joint, and the thrust pump 313 injects gas into the pneumatic expansion joint to expand and extend the pneumatic expansion joint and drive the connected sliding pressure plate 311 to move downward.

[0063] In an optional solution of this embodiment, the pneumatic actuator 312 is configured as a cylinder, the sliding pressure plate 311 is installed at the protruding end of the cylinder, and the thrust pump 313 drives the cylinder to extend to drive the sliding pressure plate 311 to move downward.

[0064] Regarding the structural composition of the second compression assembly 320, specifically:

[0065] The second compression assembly 320 includes an adsorption pump 321 and a rotating motor 322. The rotating motor 322 is installed at the bottom of the adsorption pump 321, and the adsorption pump 321 is installed at the output end of the rotating motor 322. In the first state, the circumferential opening 202 is separated from the collecting hopper 111, and the adsorption pump 321 blocks the bottom opening 203. The negative pressure generated by the adsorption pump 321 is used to apply suction to the waste material so as to suck the waste material into the compression chamber 201 and adsorb it on the adsorption pump 321, so as to prevent the waste material from directly entering the sliding box 121 from the bottom opening 203 before the compression operation. The sliding pressure plate 311 slides toward the adsorption pump 321 to reduce the volume of the compression chamber 201, thereby compressing the waste material in the compression chamber 201. In the second state, the bottom opening 203 is open, and the compression chamber 201 is connected to the accommodating space of the main box body 110 through the bottom opening 203. The airflow blown out by the adsorption pump 321 is used to apply thrust to the waste material to make the waste material separate from the adsorption pump 321. The rotating motor 322 drives the adsorption pump 321 to rotate and throws the compressed waste material into the slide box 121 through centrifugal force. The adsorption pump 321 realizes the switching between suction and ejection through the forward and reverse rotation of the internal motor.

[0066] How does the compression unit 300 limit the moving distance of the sliding cylinder 210? Specifically:

[0067] The compression unit 300 further includes a limit assembly 330, which includes a control ring seat 331 and a sliding plate 332. The second compression assembly 320 further includes an axial sleeve 323, which is sleeved on the adsorption pump 321 and the rotating motor 322 and inserted into the main housing 110. The control ring seat 331 is coaxially arranged with the bottom opening 203 and installed on the end of the sliding pump 210 close to the adsorption pump 321. One end of the sliding plate 332 is clamped on the circumferential opening 202, and the other end is threadedly connected with the control ring seat 331. In the first state, the circumferential opening 202 is separated from the collecting hopper 111, and the adsorption pump 321 is inserted into the control ring seat 331 and blocks the bottom opening 203; the abutment between the control ring seat 331 and the axial sleeve 323 is used to achieve axial limit. In the second state, the abutment between the sliding plate 332 and the collecting hopper 111 is used to achieve axial limit.

[0068] In the solution of this embodiment, a semicircular notch is provided on the side of the sliding box 121 close to the shaft sleeve 323, which is consistent with the outer wall contour of the shaft sleeve 323. The abutment between the semicircular notch and the shaft sleeve 323 is used to limit the movement distance of the sliding box 121 under the elastic force of the spring rod 122.

[0069] How the compression unit 300 limits the movable distance of the sliding pressure plate 311 is described in detail as follows:

[0070] The limiting assembly 330 further includes a rotating baffle 333, an isolation spring belt 334 and a traction element. The rotating baffle 333 is hinged to the sliding plate 332 and extends into the compression chamber 201 through the circumferential opening 202. The isolation spring belt 334 is installed on the sliding plate 332 to prevent waste from getting stuck in the hinge between the rotating baffle 333 and the sliding plate 332. The traction element is installed on the sliding plate 332 and connected to the rotating baffle 333, which can drive the rotating baffle 333 to block the diameter of the compression chamber 201 and limit the sliding range of the sliding pressure plate 311 through the contact between the rotating baffle 333 and the sliding pressure plate 311. The traction element can be set as an electric pull rod.

[0071] In order to prevent the growth of bacteria inside the slide box 121, which may cause bacterial infection to the operator when the waste inside the slide box 121 is subsequently processed, the solution of this embodiment also includes a disinfection unit 400, which includes a jet assembly 410 and a moving assembly 420. The jet assembly 410 includes a liquid storage tank 411, a drainage hose 412, a suction pump 413 and a non-return nozzle 414. The moving assembly 420 includes a slide rail 421, a rotating wheel column 422 and a control wheel 423. The slide rail 421 is installed at the top of the main box body 110, and the non-return nozzle 414 is slidably connected to the slide rail 421, and is connected to the liquid storage tank 411 through the suction pump 413 and the drainage hose 412 in turn. The rotating wheel column 422 is installed on the non-return nozzle 414, and the control wheel 423 is rotatably connected to the rotating wheel column 422, which is used to drive the non-return nozzle 414 to slide along the slide rail 421. After the waste is thrown into the slide box 121, the disinfectant in the liquid storage tank 411 is extracted by the suction pump 413 and sprayed into the slide box 121 through the non-return nozzle 414 to disinfect the bacteria and odor in the garbage.

[0072] In order to prevent bacteria from entering the liquid storage tank 411 and contaminating the unused disinfectant, in the solution of this embodiment, the non-return nozzle 414 includes a sleeve 4141, a piston nozzle 4142 and a spring ring 4143. The inner wall of the sleeve 4141 is provided with a ring-cutting groove 401, and the side wall of the piston nozzle 4142 is provided with an oblique nozzle 402. The sleeve 4141 is slidably connected to the slide rail 421, the piston nozzle 4142 is slidably connected to the ring-cutting groove 401, and the spring ring 4143 is installed in the ring-cutting groove 401. The two ends of the spring ring 4143 are respectively abutted against the piston nozzle 4142 and the sleeve 4141, and the elastic force applied by the spring ring 4143 to the piston nozzle 4142 is used to drive the piston nozzle 4142 to slide along the axial direction of the ring-cutting groove 401, so that the oblique nozzle 402 is wrapped in the sleeve 4141. The pressure of the disinfectant pumped out by the suction pump 413 can overcome the elastic force of the spring coil 4143 to push the piston nozzle 4142 to temporarily open the oblique nozzle 402, ensuring that the oblique nozzle 402 is connected to the interior of the main box 110 only when working.

[0073] In summary, the specific working process of the outdoor medical waste collection device provided in this embodiment is as follows:

[0074] Take the initial state of the feeding unit 200 as the first state as an example.

[0075] When using the device to collect medical waste outdoors, the user first pulls up the pull plate 220 and the sliding draw tube 210 through the lifting handle 221. At this time, the outer ring shell at the bottom of the sliding draw tube 210 drives the pneumatic actuator 312 to compress upward, and then the circumferential opening 202 of the sliding draw tube 210 slides out from the inside of the main box body 110. The user puts the waste into the sliding draw tube 210 through the circumferential opening 202. At this time, the adsorption pump 321 generates negative pressure to adsorb the waste on the upper surface of the adsorption pump 321. After completing a single waste delivery work, release the lifting handle 221, and the compressed pressure cylinder 230 pulls the sliding draw tube 210 downward through the rebound force to reset the sliding draw tube 210.

[0076] After the waste is put into the sliding pump 210, it will normally slide downward along the inner wall of the sliding pump 210 and then fall onto the top of the adsorption pump 321. After a single feeding is completed, the bottom end of the sliding pump 210 that has descended will be re-covered on the upper surface of the adsorption pump 321, and then the thrust pump 313 will drive the pneumatic actuator 312 to extend by pressurizing, and the sliding pressure plate 311 will slide down along the inner wall of the sliding pump 210 to directly compress the waste. At this time, the waste such as cotton or gauze blocked on the inner wall of the sliding pump 210 is directly compressed on the upper surface of the adsorption pump 321. When the sliding pump 210 is lifted up next time, the rotating motor 322 will twist the adsorption pump 321 at the same time. At this time, the adsorption pump 321 will spray the compressed waste on the upper surface upward to prevent the waste from adhering to the upper surface of the adsorption pump 321. Then the waste is thrown into the interior of the slide box 121 by the rotating centrifugal force, completing the medical waste recycling and collection work.

[0077] When idle, the operator can observe the internal garbage storage situation through the transparent main box body 110 from the outside. When the garbage storage capacity of the main box body 110 is almost full, the sliding box 121 can be pulled to the outside of the main box body 110 by the outer handle 1211, and then the garbage inside the sliding box 121 can be taken out and cleaned.

[0078] When the sliding platen 311 slides along the inner wall of the sliding cylinder 210, it will push the rotating baffle 333 to deflect downward under normal circumstances. At this time, the rotating baffle 333 will not hinder the movement of the sliding platen 311. When there is still a lot of garbage above the adsorption pump 321, it means that the garbage inside the sliding box 121 is full and needs to be cleaned in time. At this time, the rotating baffle 333 is pulled by the traction element to keep it in a fixed state, that is, when the sliding platen 311 slides along the sliding cylinder 210, it will be stuck by the rotating baffle 333 and cannot continue to move, which will cause the sliding platen 311 to be unable to compress the garbage below, thereby terminating the garbage compression work and avoiding too much compressed garbage accumulated above the adsorption pump 321.

[0079] After the waste is thrown into the sliding box 121, the suction pump 413 draws disinfectant from the liquid storage tank 411 through the drainage hose 412, and pressurizes it to the check nozzle 414. At this time, the disinfectant pressurizes and pushes the piston nozzle 4142 downward, and the piston nozzle 4142 slides out from the inner wall of the sliding sleeve 4141, and the disinfectant is diffused and sprayed downward through the opened oblique nozzle 402.

[0080] Then, the rotating wheel slides 422 on both sides perform reciprocating sliding motion along the slide rails 421 on both sides by twisting the rotating wheel 423, and the disinfectant is sprayed onto the medical waste inside the slide box 121 as much as possible through the non-return nozzle 414 at the bottom.

[0081] After the disinfection work is completed, the piston nozzle 4142 shrinks to the inside of the sliding sleeve 4141 under the elastic force of the spring coil 4143, thereby blocking the oblique nozzle 402 and isolating the non-return nozzle 414 from the inside of the main box 110.
