Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a medical waste treatment device for an intensive care unit. Background Art

[0002] During intensive care unit (ICU) treatment, the proper disposal of medical waste is crucial for ensuring a safe medical environment and preventing the spread of pathogens. This is especially true for abrasive medical waste, which contains sharp instruments like needles and blades and may carry pathogens. The collection and disposal of this waste plays a crucial role in preventing and controlling hospital infections.

[0003] Currently, the collection of harmful medical waste (such as injection needles, suture needles, disposable scissors, and scalpels) in the ICU primarily relies on sharps containers. While this has improved the efficiency of pre-processing harmful medical waste to a certain extent, the limitations of manual operation pose numerous risks. When handling medical devices contaminated with patient fluids, blood, and other contaminants, medical staff must manually open and close the sharps container. If this is not closed promptly, the sharps container can become a source of pathogenic bacteria and cause secondary contamination. To avoid this, medical staff must frequently manually open and close the sharps container, which not only increases workload and reduces work efficiency, but also easily leads to secondary infections in patients.

[0004] Based on the above problems, the present application proposes a medical waste treatment device for intensive care units to improve the above problems and prevent harmful medical waste contaminated with body fluids from becoming a secondary pollution source. Summary of the Invention

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0021] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it constitute a separate or selective embodiment that is mutually exclusive of other embodiments.

[0022] Furthermore, the present invention is described in detail with reference to schematic diagrams. For ease of illustration, when describing the embodiments of the present invention, cross-sectional views illustrating device structures may be partially enlarged and not to scale. Furthermore, the schematic diagrams are merely illustrative and should not limit the scope of protection of the present invention. Furthermore, in actual production, the three-dimensional dimensions of length, width, and depth should be included.

[0023] Please see the attached Figures 1 to 4 As shown, the first embodiment of the present invention provides a medical waste treatment device for an intensive care unit, including an outer shell 100, a bottom shell 101 is fixed to the lower end of the outer shell 100, a pedal cavity is opened inside the outer shell 100, a collection bucket 110 is detachably tied to the inner part of the outer shell 100, and the outer shell 100 and the collection bucket 110 are clearance-matched, the upper end of the outer shell 100 is rotatably connected to a top cover 120, a first feeding trough 121 is opened at the lower end of the inner part of the top cover 120, a blocking plate 130 is rotatably connected to the inner part of the top cover 120, a second feeding trough 131 is opened inside the blocking plate 130, and the first feeding trough 121 and the second feeding trough 131 are adapted to each other, and a reset cavity 122 is formed between the top cover 120 and the blocking plate 130, and further comprising: The driving unit 200 is assembled at the upper end of the bottom shell 101, and the driving unit 200 and the top cover 120, as well as the driving unit 200 and the blocking plate 130, are interconnected. The driving unit 200 includes a reset elastic member 201, which is assembled between the top cover 120 and the blocking plate 130 and is located inside the reset chamber 122. The disinfection unit 300 is assembled at the upper end of the bottom shell 101. The disinfection liquid is stored inside the disinfection unit 300, and the driving unit 200 is connected to the disinfection unit 300. The driving unit 200 can drive the disinfection unit 300 to operate synchronously; Among them, in the initial state, the first feeding trough 121 and the second feeding trough 131 are staggered from each other in the vertical direction, and the first feeding trough 121 and the second feeding trough 131 form a cover on the collection barrel 110. When the driving part 200 and the disinfection part 300 operate synchronously, the first feeding trough 121 and the second feeding trough 131 overlap with each other in the vertical direction, and the disinfection part 300 sprays atomized disinfectant liquid into the inside of the collection barrel 110.

[0024] Here, an annular support plate is integrally formed inside the outer shell 100, and a limiting plate is integrally formed on the upper end of the outer side of the collecting barrel 110. The annular support plate and the limiting plate are adapted to each other, and the outer shell 100 and the collecting barrel 110 are connected by the matching sleeve of the annular support plate and the limiting plate.

[0025] Furthermore, a medical waste bag is used in conjunction with the collection barrel 110. The medical waste bag has good toughness and markings and is used to store harmful medical waste. Specifically, medical waste bags are a mature application, and the specific type selection and usage can refer to the existing technology.

[0026] Furthermore, the reset elastic member 201 can be any one of the following elements: a spring, a coil spring or other elastic elements capable of elastic deformation. In this embodiment, the reset elastic member 201 is preferably a spring.

[0027] In this embodiment, the top cover 120 is rotated, the medical waste bag is opened and placed inside the collection bucket 110, and the top cover 120 is rotated in the opposite direction so that the top cover 120 and the blocking plate 130 cover the collection bucket 110 again. In the ICU, when collecting harmful medical waste (hereinafter referred to as waste), the driving part 200 is stepped on with the foot. The driving part 200 is driven to operate by stepping on the driving part 200, and the blocking plate 130 is driven to rotate and connect and drive the disinfection part 300 to operate. The blocking plate 130 rotates and drives the reset elastic member 201 to undergo elastic deformation. When the second feeding trough 131 and the first feeding trough 121 overlap with each other in the vertical direction, the top cover 120 and the blocking plate 130 no longer cover the collection bucket 110, and the medical staff can put the waste into the collection bucket. In the medical waste bag inside 110, medical staff do not need to open the device by hand, which reduces the risk of occupational exposure of medical staff. After the device is turned on, the occupied space will not increase. When the user's feet are separated from the driving part 200, the elastically deformed reset elastic member 201 releases elastic potential energy to restore the initial shape. The reset elastic member 201 drives the sealing plate 130 to reset, so that the second feeding trough 131 and the first feeding trough 121 are staggered with each other again. The collection barrel 110 is covered by the cooperation of the top cover 120 and the sealing plate 130, so that the waste inside the collection barrel 110 is in a closed space. The atomized disinfectant sprayed inside the collection barrel 110 can disinfect the surface of the waste, avoiding the waste contaminated with body fluids inside the collection barrel 110 from becoming a secondary pollution source.

[0028] It should be noted that in order to ensure that the reset elastic member 201 can drive the sealing plate 130 to restore its initial state, the reset elastic member 201 is always in a compressed state, and a corresponding limit lever is provided inside the top cover 120. The limit lever can limit the reset sealing plate 130 to prevent the sealing plate 130 from continuing to rotate after being reset.

[0029] Next, please refer to Figures 3 to 5The driving part 200 also includes a driving rod 202, a foot pedal 203 and a linkage rope 204. The driving rod 202 is rotatably connected to one end of the upper end of the bottom shell 101. A limiting groove 205 is provided inside the driving rod 202. The foot pedal 203 is fixed to the upper end of the driving rod 202. The linkage rope 204 is assembled between the blocking plate 130 and the driving rod 202.

[0030] Here, a plurality of anti-skid grooves are evenly arranged on the surface of the foot pedal 203. The anti-skid grooves can increase the friction between the foot pedal 203 and the user's foot to avoid slipping.

[0031] For further information, see Figure 5 and Figure 8 As shown, a sharps separation hole 123 and an avoidance hole 124 are provided inside the top cover 120. The horizontal cross-section of the sharps separation hole 123 is in the shape of a water drop. The avoidance hole 124 is adapted to the linkage rope 204, and the avoidance hole 124 passes through the inside of the linkage rope 204. A guide surface 125 is provided at an angle on the upper end of the top cover 120. The cross-section of the guide surface 125 in the vertical plane is in an inverted T-shape. The sharps separation hole 123 is provided to separate the injection needle and the syringe, and when the first feeding trough 121 and the second feeding trough 131 overlap with each other, the sharps separation hole 123 and the second feeding trough 131 also overlap with each other.

[0032] It should be noted that the portion of the linkage rope 204 located at the lower end of the avoidance hole 124 is in a vertical state, and the portion of the linkage rope 204 located at the upper end of the avoidance hole 124 is attached to the outer side of the blocking plate 130 in an arc shape. In this embodiment, when it is necessary to put waste into the collection barrel 110, the medical staff puts their feet on the surface of the foot pedal 203 and steps on it. The driving rod 202 is rotated by the fixed connection between the driving rod 202 and the foot pedal 203 and the rotation connection between the driving rod 202 and the bottom shell 101. Since the linkage rope 204 is assembled between the blocking plate 130 and the driving rod 202, the linkage rope 204 is pulled by the driving rod 202, and then the blocking plate 130 is rotated by the linkage rope 204 and the reset elastic member 201 is elastically deformed. When the first feeding trough 121 and the second feeding trough 131 overlap with each other, Medical staff can put the waste into the medical waste bag inside the collection barrel 110 for collection. After the medical staff's foot leaves the foot pedal 203, the elastically deformed reset elastic member 201 releases elastic potential energy to restore the initial shape, and drives the blocking plate 130 to reset, so that the first feeding trough 121 and the second feeding trough 131 are staggered with each other again, and then the top cover 120 and the blocking plate 130 form a cover on the collection barrel 110 again, so that the device can automatically reset without manual operation. In this process, medical staff do not need to manually open or close the device, which reduces the risk of occupational exposure of medical staff and reduces the workload of medical staff.

[0033] Secondly, please also refer to Figures 6 to 8 304, a fourth one-way valve 305, a linkage rod 306 and a plurality of nozzles 307. The liquid storage tank 301 and the corrugated piston cylinder 302 are both fixed to the upper end of the bottom shell 101. The interior of the liquid storage tank 301 is injected with disinfectant. The second one-way valve 303 is fixed to the outside of the liquid storage tank 301. The third one-way valve 304 and the fourth one-way valve 305 are both fixed to the lower end of the outside of the corrugated piston cylinder 302. The second one-way valve 303 and the third one-way valve 304 are connected by a pipeline. The linkage rod 306 is fixed to the corrugated piston cylinder 3 02, the lower end of the linkage rod 306 extends to the interior of the corrugated piston cylinder 302, and the linkage rod 306 is slidably connected to the drive rod 202, and the drive rod 202 can drive the linkage rod 306 to move in the vertical direction, and multiple nozzles 307 are fixed at the lower end of the outer side of the top cover 120 and are located at the lower end of the sealing plate 130, and the fourth one-way valve 305 and the multiple nozzles 307 are connected by a pipeline, wherein the flow direction of the third one-way valve 304 is from the second one-way valve 303 to the inside of the corrugated piston cylinder 302, and the flow direction inside the fourth one-way valve 305 is from the inside of the corrugated piston cylinder 302 to the nozzle 307.

[0034] Furthermore, a shaft rod 308 is fixed to the upper end of the linkage rod 306 , and the shaft rod 308 is slidably connected to the inside of the limiting groove 205 , and the driving rod 202 and the linkage rod 306 are slidably connected through the matching limiting groove 205 and the shaft rod 308 .

[0035] It should be noted that in the initial state, the second one-way valve 303 is immersed in the disinfectant liquid, and an avoidance molding surface is integrally formed inside the collection barrel 110, and the avoidance molding surface and the drive rod 202, the avoidance molding surface and the foot pedal 203, and the avoidance molding surface and the corrugated piston cylinder 302 are all adapted to each other.

[0036] Here, the disinfectant can be one of the following substances: 75% alcohol, sodium hypochlorite, hydrogen peroxide or other medical disinfectants with disinfection function. In this embodiment, the disinfectant is preferably 75% alcohol.

[0037] In this embodiment, when the medical staff puts waste into the collection barrel 110, they step on the foot pedal 203 to rotate the driving rod 202, and the driving rod 202 drives the linkage rod 306 to move in the vertical direction. Since the linkage rod 306 is fixedly connected to the upper end of the driving rod 202, the linkage rod 306 drives the upper end of the driving rod 202 to move, so that the driving rod 202 is compressed in the vertical direction, the space inside the corrugated piston cylinder 302 gradually decreases, and the pressure increases synchronously, so that the disinfectant inside the corrugated piston cylinder 302 passes through the fourth one-way valve 305 and the inside of the nozzle 307 in turn, and is sprayed into the collection barrel 110 in an atomized state, and the surface of the waste is disinfected by the disinfectant in the atomized state. At the same time, the top cover 120 and the sealing plate 130 no longer cover the collection barrel 110, and the medical staff can also use the disinfectant to disinfect the waste. The medical staff can put in the waste. After the waste is put in, the medical staff's feet are separated from the foot pedal 203, and the top cover 120 and the sealing plate 130 cover the collection barrel 110 again. The driving rod 202 drives the linkage rod 306 to reset, and the corrugated piston cylinder 302 synchronously restores its initial shape. The internal space of the corrugated piston cylinder 302 gradually increases, and the pressure decreases synchronously. The disinfection liquid inside the liquid storage tank 301 flows into the corrugated piston cylinder 302 through the second one-way valve 303 and the third one-way valve 304 in turn. This cycle continues. Every time waste is put in, the device performs disinfection, which can avoid incomplete disinfection caused by waste stacking and ensure the effectiveness of disinfection. At the same time, the disinfection liquid in the atomized state inside the collection barrel 110 gradually falls under the action of gravity, and can disinfect the surface of the last waste put in.

[0038] Please refer again Figures 6 to 9 A pressure plate 309 is fixed to the outside of the linkage rod 306, and the pressure plate 309 is fixedly connected to the upper end of the corrugated piston cylinder 302.

[0039] In this embodiment, when medical staff puts waste into the container, they step on the foot pedal 203 to drive the linkage rod 306 to move downward. Through the fixed connection between the linkage rod 306 and the pressure plate 309, the linkage rod 306 drives the pressure plate 309 to move synchronously. Since the upper end of the corrugated piston cylinder 302 is fixedly connected to the pressure plate 309, the pressure plate 309 can evenly squeeze the upper end of the driving rod 202, so that the top of the driving rod 202 can be evenly stressed during the compression process.

[0040] Please refer again Figure 9 A bottom plate 310 is fixed to the bottom of the corrugated piston cylinder 302, and the bottom plate 310 is fixedly connected to the bottom shell 101. The upper end of the bottom plate 310 is located on the guide sleeve 311, and the linkage rod 306 and the guide sleeve 311 are slidably connected.

[0041] In this embodiment, the provision of the guide sleeve 311 can guide the linkage rod 306 , thereby preventing the corrugated piston cylinder 302 from being twisted during the movement of the linkage rod 306 .

[0042] Please refer again Figures 2 to 4 A first one-way valve 102 is fixed to the outside of the outer shell 100, and a liquid injection hole is opened on the outside of the liquid storage tank 301. The first one-way valve 102 and the liquid injection hole are connected by a pipeline, wherein the flow inside the first one-way valve 102 is reversed from the end away from the liquid storage tank 301 to the end close to the liquid storage tank 301.

[0043] In this embodiment, the provision of the first one-way valve 102 facilitates medical personnel to inject disinfectant liquid into the liquid storage tank 301 .

[0044] It should be noted that in this embodiment, medical staff can shake the device and listen to the sound to determine whether the disinfectant liquid inside the liquid storage tank 301 needs to be replenished. Specifically, when shaking the device, if the shaking and impact feeling are obvious and the sound is obvious, it can be determined that the disinfectant liquid inside the liquid storage tank 301 is sufficient. Otherwise, the disinfectant liquid inside the liquid storage tank 301 needs to be replenished.

[0045] The working principle of the present invention is: The top cover 120 is rotated to open the medical waste bag and place it inside the collection barrel 110. The top cover 120 is rotated in the opposite direction so that the top cover 120 and the blocking plate 130 cover the collection barrel 110 again. In the ICU, when collecting waste, the foot pedal 203 is stepped on by the foot to drive the driving rod 202 to rotate and drive the linkage rod 306 to move. After the driving rod 202 rotates, the linkage rope 204 is pulled, so that the blocking plate 130 is pulled to rotate and drive the reset elastic member 201 to undergo elastic deformation. When the second feeding trough 131 and the first feeding trough 121 overlap in the vertical direction, the medical staff can put waste into the medical waste bag inside the collection barrel 110. At the same time, after the linkage rod 306 moves, it drives the pressing plate 309 to move synchronously and squeeze the upper end of the driving rod 202. The space inside the driving rod 202 becomes smaller and the pressure increases synchronously, thereby causing the disinfectant inside the driving rod 202 to pass through the first and second feeding troughs 131 and 121 in sequence. The four one-way valves 305 and the nozzle 307 spray into the collection barrel 110 in an atomized state to disinfect the surface of the waste and prevent the waste contaminated with the patient's body fluids from becoming a secondary pollution source. After the waste is put into the medical staff, the foot of the medical staff leaves the foot pedal 203, and the reset elastic member 201 releases the elastic potential energy, driving the blocking plate 130, the driving rod 202, the linkage rope 204 and the linkage rod 306 to reset synchronously. The internal space of the corrugated piston cylinder 302 increases and the pressure decreases. The disinfection liquid inside the liquid storage tank 301 flows into the corrugated piston cylinder 302 through the second one-way valve 303 and the third one-way valve 304 in turn, and the cycle operation is carried out, so that every time the medical staff puts in the waste, the device can disinfect the inside of the collection barrel 110 to prevent the waste inside the collection barrel 110 from becoming a secondary pollution source. In addition, during the process of putting in the waste, the medical staff does not need to perform manual operation, which reduces the risk of occupational exposure of the medical staff.

[0046] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained herein shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
