Description

Technical Field

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

[0002] In outdoor emergency medical situations, due to limited on-site conditions, patients cannot be immediately transferred to a more suitable treatment environment. Medical personnel must clean and bandage wounds on-site. Proper disposal of medical waste is crucial in this process to prevent environmental pollution and secondary infections, requiring specialized collection devices to recycle it. However, because medical waste contains a large amount of flexible materials such as gauze, cotton, and tissues, these materials easily expand and occupy a significant portion of the collection device's space, leading to reduced space utilization.

[0003] Existing medical waste collection bins suffer from reduced space utilization due to their inability to accommodate the easily expanding characteristics of flexible waste. Summary of the Invention

[0004] The purpose of this invention is to provide an outdoor medical waste collection device to solve the technical problem of reduced space utilization caused by the difficulty in adapting to the easily expandable characteristics of flexible waste in related technologies.

[0005] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows:

[0006] The outdoor medical waste collection device provided by this invention includes:

[0007] The system comprises a housing unit, a feeding unit, and a compression unit. The housing unit includes a main housing, and the feeding unit is mounted on the main housing. The compression unit includes a first compression component and a second compression component. The first compression component is mounted on the feeding unit, and the second compression component is mounted on the main housing. The opposing movement of the first and second compression components compresses the waste material in the feeding unit and then transfers the waste material to the receiving space of the main housing.

[0008] Specifically, the main housing is equipped with a collection hopper, which has a swivel hole. The feeding unit includes a sliding cylinder and a pull plate, with the sliding cylinder slidably connected to the swivel hole. The sliding cylinder has a compression chamber and a circumferential opening communicating with the compression chamber. The pull plate is installed on the sliding cylinder and is used to drive the sliding cylinder to slide, thereby switching the feeding unit from a first state to a second state. In the first state, the circumferential opening is isolated from the collection hopper. In the second state, the circumferential opening is connected to the collection hopper, and waste material 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 suction cylinder, the pneumatic actuator is connected to the sliding pressure plate, and the thrust pump drives the pneumatic actuator to move the sliding pressure plate. The sliding suction cylinder also has a bottom opening communicating with the compression chamber. In the first state, the circumferential opening is separated from the collection hopper, and the second compression assembly blocks the bottom opening. The sliding pressure plate slides towards the second compression assembly to reduce the volume of the compression chamber, thereby compressing the waste material in the compression chamber.

[0010] Specifically, the second compression assembly includes an adsorption pump and a rotary motor. The rotary motor is mounted at the bottom of the adsorption pump, and the adsorption pump is mounted at the output end of the rotary motor. In the first state, the circumferential opening is separated from the collection hopper, and the adsorption pump seals the bottom opening. The negative pressure generated by the adsorption pump is used to apply suction to the waste to draw it into the compression chamber and adsorb it onto the adsorption pump. The sliding pressure plate slides towards the adsorption pump to reduce the volume of the compression chamber, thereby compressing the waste in the compression chamber. In the second state, the bottom opening is open, and the compression chamber communicates with the receiving space of the main housing through the bottom opening. The airflow blown by the adsorption pump is used to apply thrust to the waste to detach it from the adsorption pump. The rotary motor drives the adsorption pump to rotate and uses centrifugal force to throw the compressed waste into the receiving space of the main housing.

[0011] Specifically, the compression unit further includes a limiting assembly, which includes a control ring seat and a sliding plate. The second compression assembly also includes a shaft sleeve, which is fitted onto 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 suction cylinder. One end of the sliding plate is engaged with 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 collection hopper, the adsorption pump is inserted into the control ring seat and blocks the bottom opening; the abutment between the control ring seat and the shaft sleeve is used to achieve axial limiting. In the second state, the abutment between the sliding plate and the collection hopper is used to achieve axial limiting.

[0012] Specifically, the limiting assembly further includes a rotating baffle, an isolation spring band, and a traction element. The rotating baffle is hinged to the sliding plate and extends through the circumferential opening into the compression chamber. The isolation spring band is installed on the sliding plate to prevent waste material from getting stuck at 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, enabling the rotating baffle to block the passage of the compression chamber and limiting the sliding range of the sliding pressure plate through the contact between the rotating baffle and the sliding pressure plate.

[0013] Specifically, it also includes a disinfection unit, which comprises a spray assembly and a moving assembly. The spray assembly includes a storage tank, a drainage hose, a pressure pump, and a check nozzle. The moving assembly includes a slide rail, a rotating roller, and a control roller. The slide rail is installed on the main housing, and the check nozzle is slidably connected to the slide rail and connected to the storage tank sequentially via the pressure pump and the drainage hose. The rotating roller is installed on the check nozzle, and the control roller is rotatably connected to the rotating roller to drive the check nozzle to slide along the slide rail.

[0014] Specifically, the check nozzle includes a sliding sleeve, a piston nozzle, and a spring ring. The inner wall of the sliding sleeve has an circumferential groove, and the side wall of the piston nozzle has an angled nozzle. The sliding sleeve is slidably connected to the slide rail, the piston nozzle is slidably connected to the circumferential groove, and the spring ring is installed in the circumferential groove. The spring ring drives the piston to slide along the circumferential groove, thereby blocking the angled nozzle. The pressure of the disinfectant pumped by the pump overcomes the elasticity of the spring ring, pushing the piston nozzle to temporarily open the angled nozzle.

[0015] Specifically, the feeding unit further includes a pressure cylinder sleeved on the sliding drum. The pressure cylinder is configured as an elastic element, and its two ends abut against the sliding drum and the collection hopper, respectively. The pressure cylinder is used to apply a thrust to the sliding drum to switch the feeding unit from the second state to the first state.

[0016] Specifically, the housing unit further includes a side drawer assembly, which comprises a sliding box and a spring rod. The sliding box is slidably connected to the main housing and is used to store compressed waste. The two ends of the spring rod abut against the main housing and the sliding box, respectively, to apply a pushing force to the sliding box, thereby causing the sliding box to slide and retract into the main housing.

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

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

[0019] The system comprises a housing unit, a feeding unit, and a compression unit. The housing unit includes a main housing, and the feeding unit is mounted on the main housing. The compression unit includes a first compression component and a second compression component. The first compression component is mounted on the feeding unit, and the second compression component is mounted on the main housing. The opposing movement of the first and second compression components compresses the waste material in the feeding unit and then transfers the waste material to the receiving space of the main housing.

[0020] In practical applications, medical waste generated during the cleaning process is put into the outdoor medical waste collection device. The put-in waste first enters the feeding unit, activating the first compression component and the second compression component to move in opposite directions to squeeze the waste inside the feeding unit. The compressed waste is then transferred to the accommodating space of the main box.

[0021] As can be seen, compared with existing technologies, this outdoor medical waste collection device, through the feeding unit and the cooperation of the first and second compression components, allows flexible waste to first enter the feeding unit for compression before being transferred to the main body, reducing the space occupied by flexible waste. This overcomes the technical problem of reduced space utilization caused by the difficulty in adapting to the easily expanding characteristics of flexible waste in existing medical waste collection boxes.

The units of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0047] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0048] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0049] Existing medical waste collection bins suffer from reduced space utilization due to their inability to accommodate the easily expanding characteristics of flexible waste.

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

[0051] The system comprises a housing unit 100, a feeding unit 200, and a compression unit 300. The housing unit 100 includes a main housing 110, and the feeding unit 200 is mounted on the main housing 110. The compression unit 300 includes a first compression component 310 and a second compression component 320. The first compression component 310 is mounted on the feeding unit 200, and the second compression component 320 is mounted on the main housing 110. The opposing movement of the first compression component 310 and the second compression component 320 compresses the waste material in the feeding unit 200 and then transfers the waste material to the receiving space of the main housing 110.

[0052] In summary, the outdoor medical waste collection device provided by this invention achieves the following technical effects:

[0053] This outdoor medical waste collection device, through the combination of a feeding unit 200 and a first compression component 310 and a second compression component 320, allows flexible medical waste to first enter the feeding unit 200 for compression before being transferred to the main container 110, reducing the space occupied by the waste. This overcomes the technical problem of reduced space utilization caused by the difficulty in adapting to the easily expanding characteristics of flexible waste in existing medical waste collection boxes.

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

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

[0056] The housing unit 100 also includes a side drawer assembly 120, which includes a sliding box 121 and a spring rod 122. The sliding box 121 is slidably connected to the main housing 110 and is used to store compressed waste. The two ends of the spring rod 122 abut against the main housing 110 and the sliding box 121 respectively, applying a pushing force to the sliding box 121 to cause it to slide and retract into the main housing 110. The sliding box 121 is provided with a handle 1211, used to overcome the elastic force of the spring rod 122 to pull the sliding box 121 and open its internal space. The main housing 110 is made of transparent material.

[0057] Specifically, regarding how the waste material enters the feeding unit 200:

[0058] In this embodiment, the main housing 110 is equipped with a collection hopper 111, which has a sliding groove. The feeding unit 200 includes a sliding drum 210 and a pull plate 220, with the sliding drum 210 slidably connected to the sliding groove. The sliding drum 210 is configured as a compression chamber 201 and a circumferential opening 202 communicating with the compression chamber 201. The pull plate 220 is installed on the sliding drum 210 and is equipped with a lifting handle 221, which is used to drive the sliding drum 210 to slide so that the feeding unit 200 switches from a first state to a second state. In the first state, the circumferential opening 202 is separated from the collection hopper 111. In the second state, the circumferential opening 202 communicates with the collection hopper 111, and waste material enters the compression chamber 201 through the circumferential opening 202. After releasing the lifting handle 221, under the action of gravity, the sliding drum 210 moves downward so that the feeding unit 200 switches from the second state to the first state, thereby closing the circumferential opening 202.

[0059] To prevent the leakage of toxic and foul-smelling gases from the waste inside the housing unit 100, which could adversely affect the medical environment, the feeding unit 200 in this embodiment further includes a pressure cylinder 230 sleeved on the sliding drawer 210. The pressure cylinder 230 is an elastic element, with its two ends abutting against the sliding drawer 210 and the collection hopper 111, respectively. The elasticity of the pressure cylinder 230 applies a pushing force to the sliding drawer 210 to switch the feeding unit 200 from the second state to the first state. Simultaneously, the pressure cylinder 230 further enhances the sealing performance of the housing unit 100 by encasing the sliding drawer 210.

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

[0061] In 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 suction cylinder 210, the pneumatic actuator 312 is connected to the sliding pressure plate 311, and the thrust pump 313 drives the pneumatic actuator 312 to drive the sliding pressure plate 311 to slide. The sliding suction cylinder 210 also has a bottom opening 203 communicating with the compression chamber 201. In the first state, the circumferential opening 202 is separated from the collection hopper 111, and the second compression assembly 320 blocks the bottom opening 203. The sliding pressure plate 311 slides towards the second compression assembly 320 to reduce the volume of the compression chamber 201, thereby compressing the waste material in the compression chamber 201. The sliding suction cylinder 210 also has a through hole 204, which serves as the air inlet of the thrust pump 313.

[0062] In an optional 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 cause the pneumatic expansion joint to expand and extend, thereby driving the connected sliding pressure plate 311 to move downward.

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

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

[0065] The second compression assembly 320 includes an adsorption pump 321 and a rotary motor 322. The rotary motor 322 is mounted at the bottom of the adsorption pump 321, and the adsorption pump 321 is mounted at the output end of the rotary motor 322. In the first state, the circumferential opening 202 is separated from the collection hopper 111, and the adsorption pump 321 seals the bottom opening 203. The negative pressure generated by the adsorption pump 321 is used to apply suction to the waste to draw the waste into the compression chamber 201 and adsorb it onto the adsorption pump 321, preventing the waste from directly entering the slide box 121 from the bottom opening 203 before compression. The sliding pressure plate 311 slides towards the adsorption pump 321 to reduce the volume of the compression chamber 201, thereby compressing the waste in the compression chamber 201. In the second state, the bottom opening 203 is open, and the compression chamber 201 communicates with the receiving space of the main box 110 through the bottom opening 203. The airflow blown out by the adsorption pump 321 is used to apply thrust to the waste material so that the waste material is detached 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 switches between suction and jetting by rotating its internal motor in both directions.

[0066] Specifically, regarding how the compression unit 300 limits the movement distance of the sliding drum 210:

[0067] The compression unit 300 also includes a limiting component 330, which includes a control ring seat 331 and a sliding plate 332. The second compression component 320 also includes a shaft sleeve 323, which is fitted onto 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 sliding suction cylinder 210 near the adsorption pump 321. One end of the sliding plate 332 is engaged with the circumferential opening 202, and the other end is threadedly connected to the control ring seat 331. In the first state, the circumferential opening 202 is separated from the collection hopper 111, the adsorption pump 321 is inserted into the control ring seat 331 and blocks the bottom opening 203; the contact between the control ring seat 331 and the shaft sleeve 323 is used to achieve axial limiting. In the second state, the contact between the sliding plate 332 and the collection hopper 111 is used to achieve axial limiting.

[0068] In this embodiment, the slide box 121 has a semi-circular notch on the side near the shaft sleeve 323 that matches the outer contour of the shaft sleeve 323. The contact between the semi-circular notch and the shaft sleeve 323 limits the movement distance of the slide box 121 under the elastic force of the spring rod 122.

[0069] Specifically, regarding how the compression unit 300 limits the travel distance of the sliding pressure plate 311:

[0070] The limiting assembly 330 also includes a rotating baffle 333, an isolation spring band 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 band 334 is installed on the sliding plate 332 to prevent waste material from getting stuck at 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. It can drive the rotating baffle 333 to block the passage of the compression chamber 201 and limit the sliding range of the sliding pressure plate 311 by abutting against it. The traction element can be configured as an electric pull rod.

[0071] To prevent the excessive growth of bacteria inside the slide box 121, which could lead to bacterial infection of operators during subsequent waste processing, this embodiment also includes a disinfection unit 400. The disinfection unit 400 includes a spray assembly 410 and a moving assembly 420. The spray assembly 410 includes a storage tank 411, a drainage hose 412, a pump 413, and a check nozzle 414. The moving assembly 420 includes a slide rail 421, a rotary slide column 422, and a control wheel 423. The slide rail 421 is installed at the top of the main housing 110. The check nozzle 414 is slidably connected to the slide rail 421 and is connected to the storage tank 411 sequentially via the pump 413 and the drainage hose 412. The rotary slide column 422 is installed on the check nozzle 414, and the control wheel 423 is rotatably connected to the rotary slide column 422 to drive the check nozzle 414 to slide along the slide rail 421. After the waste is thrown into the slide box 121, the disinfectant in the storage tank 411 is drawn by the pump 413 and sprayed into the slide box 121 through the check nozzle 414 to disinfect the bacteria and odor in the waste.

[0072] To prevent bacteria from entering the storage tank 411 and contaminating unused disinfectant, in this embodiment, the check nozzle 414 includes a sliding sleeve 4141, a piston nozzle 4142, and a spring ring 4143. The inner wall of the sliding sleeve 4141 has an annular groove 401, and the side wall of the piston nozzle 4142 has an oblique nozzle 402. The sliding sleeve 4141 is slidably connected to the slide rail 421, the piston nozzle 4142 is slidably connected to the annular groove 401, and the spring ring 4143 is installed in the annular groove 401. The two ends of the spring ring 4143 abut against the piston nozzle 4142 and the sliding sleeve 4141, respectively. The elastic force applied by the spring ring 4143 to the piston nozzle 4142 drives the piston nozzle 4142 to slide along the axial direction of the annular groove 401, thereby enclosing the oblique nozzle 402 within the sliding sleeve 4141. The pressure of the disinfectant pumped out by the pressure pump 413 can overcome the elastic force of the spring ring 4143 to push the piston nozzle 4142 to temporarily open the angled nozzle 402, ensuring that the angled nozzle 402 is connected to the interior of the main housing 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] Taking the initial state of the feeding unit 200 as the first state as an example.

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

[0076] After the waste is fed into the sliding drum 210, it will normally slide down the inner wall of the sliding drum 210 and fall onto the adsorption pump 321. After a single feeding, the bottom of the sliding drum 210 will be reattached to the upper surface of the adsorption pump 321. Then, the thrust pump 313 will push the pneumatic actuator 312 by pressurizing, and the sliding pressure plate 311 will slide down the inner wall of the sliding drum 210 to directly compress the waste. At this time, the cotton or gauze and other waste blocking the inner wall of the sliding drum 210 will be directly compressed onto the upper surface of the adsorption pump 321. When the sliding drum 210 is lifted up again, the rotating motor 322 will rotate the adsorption pump 321. 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 will be thrown into the sliding box 121 by the centrifugal force of rotation, completing the medical waste recycling and collection work.

[0077] When not in use, the operator can observe the garbage capacity inside the transparent main container 110 from the outside. When the garbage storage capacity of the main container 110 is almost full, the sliding box 121 can be pulled to the outside of the main container 110 through the handle 1211 on the outside, and then the garbage inside the sliding box 121 can be removed and cleaned.

[0078] When the sliding pressure plate 311 slides along the inner wall of the sliding suction cylinder 210, it will normally push the rotating baffle 333 to deflect downwards. At this time, the rotating baffle 333 will not obstruct the movement of the sliding pressure plate 311. When there is still a large amount of garbage above the adsorption pump 321, it means that the garbage inside the slide 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 pressure plate 311 slides along the sliding suction cylinder 210, it will be stuck by the rotating baffle 333 and cannot continue to move. This will cause the sliding pressure plate 311 to be unable to compress the garbage below, thereby terminating the garbage compression work and avoiding excessive accumulation of compressed garbage above the adsorption pump 321.

[0079] After the waste is thrown into the slide box 121, the pump 413 draws disinfectant from the storage tank 411 through the drainage hose 412 and pressurizes it to deliver it to the check nozzle 414. At this time, the disinfectant pressurizes and pushes the piston nozzle 4142 downward. The piston nozzle 4142 slides out from the inner wall of the slide sleeve 4141, and the disinfectant diffuses and sprays downward through the open angled nozzle 402.

[0080] Then, the rotating rollers 422 on both sides slide back and forth along the slide rails 421 by twisting the rotating rollers 423, and spray the disinfectant onto the medical waste inside the slide box 121 as much as possible through the anti-reverse nozzles 414 at the bottom.

[0081] After the disinfection work is completed, the piston nozzle 4142 retracts into the inside of the sliding sleeve 4141 under the elastic force of the spring ring 4143, thereby blocking the oblique nozzle 402 and isolating the check nozzle 414 from the inside of the main housing 110.

[0082] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
