Description

Technical Field

[0001] This utility model belongs to the technical field of operating room equipment, specifically relating to a sterilized trash can for medical waste in operating rooms. Background Technology

[0002] The handling of medical waste in the operating room is an important part of hospital infection control. The medical waste bins currently in use have significant technical defects: the traditional design only uses a single top cover structure, which creates a completely exposed state when the waste is opened and disposed of. The laminar flow system in the operating room will carry bacterial aerosols to spread, resulting in the bacterial concentration within 30cm when the single cover is open being more than 3 times the operating room environmental standard.

[0003] Existing trash cans generally lack instant disinfection functions. 78% of standard models cannot disinfect simultaneously when discarding trash, resulting in bioaerosols (particle size <5μm) generated by accumulated waste remaining suspended for 2-4 hours. Special pollutants, such as bone fragments from orthopedic surgery, may even puncture the trash bag, causing leakage and contamination. More seriously, a single opening operation will disrupt the negative pressure environment inside the can, causing aerosols containing drug-resistant bacteria such as MRSA to spread outward. Studies have confirmed that this diffusion can increase the number of airborne bacteria within a 2m radius by 40%. In addition, traditional foot-operated opening mechanisms have a delay of 0.5-1 second, which is enough time for a large number of pollutants to escape. The high frequency of use in operating rooms (15-20 openings per hour on average) further exacerbates the risk of contamination.

[0004] While ultraviolet-sterilized trash cans offer some improvements, their periodic disinfection mode cannot meet the immediate protection needs of each opening, and their disinfection effectiveness for damp waste is reduced by more than 60%. These problems are particularly prominent when performing infectious surgeries (such as surgery on tuberculosis patients), and the existing trash can structure has become a weak link in infection control in operating rooms. Therefore, this utility model proposes a sterilized trash can for medical waste in operating rooms to address the above-mentioned problems. Utility Model Content

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figure 1-5 As shown, a sterilized trash can for medical waste in an operating room includes a cylinder 1, a step-linkage mechanism 2, and a secondary inner sealing mechanism 3. The step-linkage mechanism 2 is installed on the cylinder 1 and corresponds to the secondary inner sealing mechanism 3. The secondary inner sealing mechanism 3 is installed inside the cylinder 1, and a bagging mechanism 4 that cooperates with the secondary inner sealing mechanism 3 is installed inside the cylinder 1.

[0028] A nozzle 5 is installed on the opposite side above the secondary inner sealing mechanism 3 inside the cylinder 1. A delivery pump assembly 6 is provided on the side of the cylinder 1. The delivery pump assembly 6 includes a delivery pump, a delivery pipe and an inlet pipe installed on the side of the cylinder 1. The delivery pipe is interconnected with the nozzle 5 and the outlet end of the delivery pump. The inlet pipe is installed on the storage tank 7 and the inlet end of the delivery pump. The storage tank 7 is installed on the side of the cylinder 1. A battery assembly 8 is installed on the side of the cylinder 1 below the storage tank 7. The battery assembly 8 includes a mounting frame and a battery. The battery is installed in the mounting frame. The mounting frame is installed on the side of the cylinder 1. A controller 9 is installed on the side of the cylinder 1 below the mounting frame. The controller 9 is equipped with a control program that is linked to the trigger 24 and the delivery pump. The time for each start-up of the delivery pump is not less than 5 seconds.

[0029] As an optional implementation, the foot-operated linkage mechanism 2 includes a flip cover 21, a mounting plate 25, and a foot pedal 27. The flip cover 21 is flipped and snapped into place on the upper side of the cylinder 1. A flip plate 22 and a hinge seat 23 are provided on the side of the cylinder 1. One side of the flip plate 22 is rotatably mounted on the side of the cylinder 1 through the hinge seat 23, and the other side is fixed on the side of the flip plate 22. The mounting plate 25 is installed on the bottom surface of the cylinder 1 on the side corresponding to the flip plate 22. A linkage rope 28 is provided on the outer side of the cylinder 1. The linkage rope 28 is configured as a closed loop with both ends tied together. Its upper side is fitted into the through hole opened on the flip plate 22. Two grooved wheels 26 are provided on the bottom surface of the cylinder 1 corresponding to the flip plate 22. The two sides of the linkage rope 28 are fitted onto the two grooved wheels 26. The two grooved wheels 26 are rotatably mounted on both sides of the mounting plate 25. In this way, the flip cover 21 can be flipped open by foot operation through the cooperation of the linkage rope 28 and the foot pedal 27, which facilitates the disposal operation by medical staff.

[0030] See attached document Figure 2 and attached Figure 3 The foot pedal 27 is located on the bottom surface of the cylinder 1 away from the mounting plate 25. The linkage rope 28 passes around the groove wheel 26 and its other side is fitted into the rope hole opened on the foot pedal 27. An inner bottom plate 10 is fixedly installed inside the cylinder 1. A fixing plate 29 corresponding to the foot pedal 27 is installed below the inner bottom plate 10. The lower side of the fixing plate 29 rotates with the foot pedal 27. A trigger 24 is installed on the foot pedal 27. This allows the operator to step on the foot pedal 27 and simultaneously step on the trigger 24, thereby transmitting a signal to the controller 9 to control the delivery pump to draw disinfectant from the storage tank 7 and spray it out through the nozzle 5 to disinfect discarded medical waste. At the same time, the disinfectant is suppressed when the secondary inner sealing mechanism 3 is open to prevent bacteria from overflowing.

[0031] See attached document Figure 4 The secondary inner sealing mechanism 3 includes two opposing plates 31, two sets of bending connecting rods 32, and two lifting ropes 33. The two opposing plates 31 are set on the same horizontal plane and located inside the cylinder 1. The opposite sides of the two opposing plates 31 are slidably fitted into the sliding holes on the opposite sides of the two sliding perforated plates 11. The two sliding perforated plates 11 are fixed to the upper side inside the cylinder 1. Two extrusion springs 34 are fitted into the sliding holes on the sliding perforated plates 11. The extrusion springs 34 are set in the sliding holes on the opposite sides of the opposing plates 31 and are fixedly connected to the sides of the opposing plates 31. The elastic force of the extrusion springs 34 is set at 8-15N. Rubber buffer pads are attached to the opposite sides of the two opposing plates 31. After the flip cover 21 is closed, the extrusion springs 34 push the two opposing plates 31 to move relative to each other, thereby sealing the channel between the two sliding perforated plates 11 and thus blocking bacteria in the enclosure 41.

[0032] Furthermore, two sets of bending connecting rods 32 are set on the opposite sides of the two splicing plates 31, and the opposite ends of the bending connecting rods 32 are rotatably connected to the opposite sides of the bottom surface of the two splicing plates 31 through the hinge seat 23. The lifting rope 33 is set between the two splicing plates 31 and is tied to the central shaft 32a on the lower side. The central shaft 32a is rotatably installed at the bend of the bending connecting rod 32. The upper side of the lifting rope 33 is fixed on the cover block 33a, which is fixed on the inner side of the flip cover 21. In this way, when the flip cover 21 is flipped upward, the lifting rope 33 will pull the bending connecting rod 32 upward, so that the bending connecting rod 32 will push the two splicing plates 31 away from each other, thereby opening the channel between the two sliding plate 11, which is convenient for medical staff to discard medical waste into the enclosure 41.

[0033] Furthermore, when the two sets of bending connecting rods 32 bend downwards, they fit perfectly inside the frame 41 on both sides. The length of the bending connecting rods 32 after being straightened is greater than the distance between the opposite sides of the two sliding plate 11. This allows the lifting rope 33 to pull the bending connecting rods 32 upwards, thus pushing the two opposing plates 31 away from each other and preventing the bending connecting rods 32 from bending upwards and affecting subsequent operations.

[0034] See attached document Figure 5 The bagging mechanism 4 includes two frames 41 and a fitting cover 43. The side plate of the cylinder 1 corresponding to the foot pedal 27 has an inner insertion hole. Both frames 41 are inserted into the inner insertion hole. Two sets of vertical plates 42 are fixed between the two frames 41. The fitting cover 43 is fitted into the inner insertion hole and fixed on the side of one set of vertical plates 42. A pull plate 44 is fixed on the outer side of the fitting cover 43. This allows the operator to pull the bagging mechanism 4 out of the cylinder 1 through the pull plate 44, thereby collecting and disposing of discarded medical waste.

[0035] Using the above structure, the following steps are included:

[0036] 1. Trampling Trigger Phase

[0037] When medical staff step on the pedal 27, the flip plate 22 is pulled by the linkage rope 28, which drives the flip cover 21 to flip upward and open around the hinge seat 23;

[0038] Synchronously, when the pedal 27 is pressed, the trigger 24 is activated, which transmits a signal to the controller 9 to start the delivery pump assembly 6.

[0039] 2. Disinfectant spraying and inner seal opening

[0040] The delivery pump draws disinfectant from the storage tank 7, delivers it through the delivery pipe to the atomizing nozzle 5 and sprays it out. Before the flip cover 21 on the cylinder 1 is opened, the atomized disinfectant covers the opening area of ​​the cylinder 1.

[0041] When the flip cover 21 is opened, the two opposing plates 31 of the secondary inner sealing mechanism 3 are pulled away from each other by the lifting rope 33, thus releasing the sealing of the bagging mechanism 4.

[0042] 3. Waste disposal and antibacterial protection

[0043] Medical waste falls into the collection bag of the bagging mechanism 4 through the opening, and the sprayed disinfectant immediately disinfects its surface.

[0044] 4. Closure and Residual Disinfection

[0045] After the pedal 27 is released, the flip cover 21 is pressed down, and the extrusion spring 34 pushes the two opposing plates 31 to move relative to each other to the closed state.

[0046] During the closing process:

[0047] Disinfectant droplets remain between the splicing plate 31 and the flip cover 21, continuously disinfecting the contact surface;

[0048] The double-layer closed structure (flip-top 21 + splicing plate 31) blocks the escape route of bacteria.

[0049] This trash can combines electromechanical linkage with structural design to meet the high-frequency, high-safety waste disposal needs of the operating room.
