Technical Field

[0001] The present invention relates to the technical field of medical waste treatment, and particularly to a disinfection chamber cover of a medical waste disinfection device. Background Art

[0002] Medical waste is special waste with direct or indirect infectivity, toxicity and other hazards generated by medical and health institutions during activities such as diagnosis and treatment, scientific research, etc. Its safe disposal is an important link in the fields of public health management and environmental protection. Improper treatment may lead to serious consequences such as pathogen transmission and environmental pollution. Therefore, efficient and reliable disinfection equipment is one of the core equipment in the harmless treatment chain of medical waste.

[0003] The patent publication number of the existing patent application is: CN208301906U, and the publication date is January 1, 2019. The name of this patent is "A mechanical structure for opening, closing and locking the centrifuge chamber cover". This patent includes a centrifuge chamber body, a chamber cover assembly, and a cover lock assembly. The chamber cover assembly is located on the centrifuge chamber body, and the cover lock assembly is located at one end of the chamber cover assembly. The cover lock assembly includes a locking nut and a locking rod. The locking nut is located above the locking rod. A limiting hole is provided inside the locking nut, and a locking nut stop block is provided at the limiting hole. Two limiting grooves are symmetrically provided at the upper conical surface of the locking rod. A limiting pin is provided on the limiting groove. A spring is provided at the lower end of the locking rod, and a limiting block is provided at the bottom end of the locking rod. A thrust ball bearing is provided between the limiting block and the locking rod. Three ball head set screws are also symmetrically provided at the upper end of the locking rod. A limiting stop block is provided on the centrifuge chamber body. This utility model has a reasonable structure, precise cooperation, convenient operation, good smoothness, improves work efficiency and operation convenience, and at the same time can prevent misoperation of a single unlocking action.

[0004] The above application has deficiencies. The chamber cover locking mechanism often has complex operations, which requires staff to spend more time and energy to operate, reducing the waste treatment efficiency. Secondly, due to the unreasonable design of the locking mechanism, it is easy to have situations of incomplete locking or excessive locking, resulting in poor sealing or damage of the chamber cover. In addition, during the disinfection process of the chamber cover of the existing medical waste disinfection equipment, the use of biological indicators is often ignored. Biological indicators are a reliable tool for monitoring the disinfection effect. It can simulate the survival situation of microorganisms during the disinfection process, thereby judging whether the disinfection is qualified. However, the traditional chamber cover design does not provide a suitable storage and observation position for biological indicators, or the access to biological indicators is not convenient enough, making the use of biological indicators difficult.

[0031] To make the objectives, technical solutions and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are some but not all of the embodiments of the present disclosure. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0032] Please refer to Figure 1-8 , a disinfection hatch cover of a medical waste disinfection device provided by an embodiment of the present invention includes a bracket 1 installed at the hatch opening and a crossbeam 2 hinged to the bracket 1. It further includes a hatch body 3 located below the crossbeam 2, and an observation pipe 4 is installed through between the hatch body 3 and the crossbeam 2. Transparent panels 43 are installed at both the upper and lower pipe orifices of the observation pipe 4. A locking mechanism 5 is movably installed inside the hatch body 3. An adjustment kit 6 for driving the locking mechanism 5 is rotatably sleeved outside the observation pipe 4. A keyhole 11 corresponding to the locking mechanism 5 is provided on the bracket 1. A biological indicator storage tube 7 is fixed to the bottom surface of the hatch body 3 and has openings 71 at both ends. An anti-disengagement limit assembly 8 for covering the openings 71 and locking the locking mechanism 5 is installed in the hatch body 3. One end of the anti-disengagement limit assembly 8 abuts against the outer wall of the observation pipe 4. After the adjustment kit 6 drives the locking mechanism 5 to insert into the keyhole 11, the observation pipe 4 is rotated to make the anti-disengagement limit assembly 8 be engaged with the locking mechanism 5 in a limited state.

[0033] Specifically, the bracket 1 is fixed at the hatch of the disinfection cabin, and the bracket 1 and the disinfection cabin are connected by fasteners. One end of the crossbeam 2 is connected to the bracket 1 in a hinged manner, so that the crossbeam 2 can drive the hatch cover body 3 to flip around the hinge point to realize the opening and closing of the disinfection cabin. A pulling frame is also sleeved on the crossbeam 2, and the bottom of the pulling frame is fixed to the top surface of the hatch cover body 3. The hatch cover body 3 is a flat plate structure, and its bottom surface size matches the hatch of the disinfection cabin. The inner cavity 31 is inside the hatch cover body 3, which is used to install the locking mechanism 5 and Other related parts, both ends of the biological indicator storage tube 7 have openings 71, which can be used to quickly place biological indicators. Biological indicators provide the ultimate verification of sterilization effects by simulating the survival state of the most difficult-to-kill microorganisms. Its use is the core link of medical sterilization quality control to ensure that the sterilization process of the disinfection cabin truly meets the "sterile" requirements. When it is necessary to close the hatch cover body 3, first pull the crossbeam 2 and the hatch cover body 3 toward the hatch of the disinfection cabin manually or electrically, so that the hatch cover body 3 is closed in the hatch, and then After that, the adjusting kit 6 is turned, and the adjusting kit 6 can also be connected to the driving source and driven electrically. During the rotation process, the locking element of the locking mechanism 5 is driven to move radially and be inserted into the corresponding locking hole 11 on the bracket 1. After being inserted into the locking hole 11, the observation pipe 4 is rotated separately to drive the anti-slip limit assembly 8 to be engaged with the locking mechanism 5 in the limited state, that is, the anti-slip limit assembly 8 itself is also limited, so that when the locking operation of the hatch cover is completed, it can also ensure that the tube mouth of the biological indicator storage tube 7 is always in a closed state in the disinfection cabin. When it is necessary to open the hatch cover, the observation pipe 4 is first rotated in the opposite direction to separate the anti-slip limit assembly 8 from the locking mechanism 5, and then, the adjusting kit 6 is used to drive the adjusting disk 62 to reverse to drive the locking element of the locking mechanism 5 to move radially and be pulled out from the locking hole 11. Finally, the crossbeam 2 and the hatch cover body 3 are lifted from the hatch of the disinfection cabin manually or electrically to complete the opening operation of the hatch cover. During the disinfection process, the staff can intuitively understand the disinfection situation in the cabin through the observation pipe 4.

[0034] Compared with the prior art, in the embodiment of the present invention, by providing a locking mechanism 5 and an adjustment kit 6, rapid locking and unlocking of the hatch cover are achieved. At the same time, further engagement between the anti-disengagement limiting component 8 and the locking mechanism 5 is used to determine whether the locking mechanism 5 is in the correct locking position, avoiding the situations of insufficient locking or excessive locking, ensuring the service life of the hatch cover seal. Secondly, the observation pipeline 4 in the hatch cover body 3 allows the staff to directly understand the disinfection situation inside the cabin, improving the transparency and controllability of the disinfection work. The design of the adjustment kit 6 makes the driving of the locking mechanism 5 and the rotation of the observation pipeline 4 interrelated, further simplifying the operation process. In addition, in this solution, a biological indicator storage tube 7 is provided on the bottom surface of the hatch cover body 3, and an anti-disengagement limiting component 8 for covering the opening 71 and locking the locking mechanism 5 is equipped. The design of the biological indicator storage tube 7 provides a suitable storage position for the biological indicator. When the locking mechanism 5 is unlocked, the anti-disengagement limiting component 8 can quickly move away from the two ends of the opening 71 of the biological indicator storage tube 7. When the locking mechanism 5 locks the hatch cover body 3 and the disinfection chamber, adjusting the observation pipeline 4 can lock the anti-disengagement limiting component 8 in place and engage with the locking mechanism 5, ensuring the stability and safety of the biological indicator during the disinfection process.

[0035] In a further technical solution of the present invention, one end of the cross beam 2 is fixedly connected with a connecting rod 21. A hydraulic telescopic rod 22 is hinged on the connecting rod 21. The bottom of the hydraulic telescopic rod 22 is hinged with a mounting bracket 23. Specifically, the connecting rod 21 serves as a connecting bridge, playing a role in supporting and transmitting force. The hydraulic telescopic rod 22 connected to the connecting rod 21 can be telescoped as needed to adjust its length. The mounting bracket 23 at the bottom of the hydraulic telescopic rod 22 can be fixed on the side wall of the cabin body of the disinfection chamber. When the hatch cover needs to be closed, the hydraulic telescopic rod 22 is activated, and its piston rod extends, pushing the cross beam 2 and the connected hatch cover body 3 to rotate around the hinge axis on the bracket 1 until the hatch cover body 3 closely fits on the hatch opening of the disinfection chamber. At this time, the locking mechanism 5 is driven by the adjustment kit 6 to insert into the lock hole 11, and the observation pipeline 4 is rotated to make the anti-disengagement limiting component 8 engage with the locking mechanism 5 to complete the locking operation of the hatch cover. When the hatch cover needs to be opened, the locking mechanism 5 is unlocked, the piston rod of the hydraulic telescopic rod 22 retracts, pulling the cross beam 2 and the hatch cover body 3 to rotate reversely around the hinge axis, and the hatch cover can be easily opened. Since there is no need for manual opening of the cover, the biological indicator can be taken down more quickly.

[0036] In a further technical solution of the present invention, an inner cavity 31 is provided in the hatch cover body 3. The locking mechanism 5 includes a plurality of locking rods 51 that move radially and are annularly distributed at the top of the inner cavity 31. An anti-deviation frame 52 through which the locking rods 51 pass is installed in the inner cavity 31. Specifically, by providing the annularly distributed locking rods 51 and the anti-deviation frame 52 in the inner cavity 31, a simple and effective hatch cover locking mechanism is realized. The locking rods 51 move radially under the driving action of the adjustment kit 6, and move from the center of the hatch cover body 3 to the edge along the direction set by the anti-deviation frame 52 until each locking rod 51 is inserted into the corresponding lock hole 11 at the same time, completing the locking of the hatch cover. When unlocking, the adjustment kit 6 is flipped to make the locking rods 51 move radially inward and withdraw from the lock holes 11. This design not only improves the stability and safety of the hatch cover, but also makes the opening and closing operations of the hatch cover more convenient and efficient. This locking method is also more direct and reliable because it can lock the support 1 fixed on the hatch opening in multiple directions, avoiding the situation that a certain area of the hatch cover is not firmly connected to the disinfection chamber in case of an accident.

[0037] In a further technical solution of the present invention, the bottom end of the observation pipe 4 penetrates through the hatch cover body 3 and is fixedly connected with a lower anti-disengagement ring 41, and the top end of the observation pipe 4 penetrates through the cross beam 2 and is fixedly connected with an upper anti-disengagement ring 42. Transparent panels 43 are embedded in both the upper anti-disengagement ring 42 and the lower anti-disengagement ring 41. Specifically, the observation pipe 4 is inserted into the through holes preset on the cross beam 2 and the hatch cover body 3, and both the upper anti-disengagement ring 42 and the lower anti-disengagement ring 41 are closely attached to their respective installation surfaces to provide good sealing performance and stability. In addition, the transparent panels 43 in the upper anti-disengagement ring 42 and the lower anti-disengagement ring 41 are made of high-strength and high-transparency materials, such as tempered glass or transparent plastic. Without opening the hatch cover body 3, the equipment or environmental state below the hatch cover can be directly observed through the transparent panels 43, which not only ensures the integrity and safety of the hatch cover structure, but also improves the convenience of observation and monitoring, effectively reducing the maintenance cost and safety risk. At the same time, the observation pipe 4 can also play the role of connecting the cross beam 2 and the hatch cover body 3, eliminating the need to additionally install connecting parts between the cross beam 2 and the hatch cover body 3.

[0038] In a further technical solution of the present invention, the adjustment kit 6 includes a connecting sleeve 61 sleeved outside the observation pipeline 4. At the bottom end of the connecting sleeve 61, an adjustment disc 62 is installed in the inner cavity 31. A number of arc-shaped guide grooves 63 are annularly distributed on the adjustment disc 62. One end of the locking rod 51 is rotatably connected to a docking transmission rod 55 inserted into the corresponding arc-shaped guide groove 63. Specifically, when the connecting sleeve 61 is rotated to drive the adjustment disc 62 to rotate, due to the change in the position of each arc-shaped guide groove 63, after the docking transmission rod 55 is squeezed by the inner wall of the arc-shaped guide groove 63, the locking rod 51 that moves radially in a single direction is forced to move towards the edge of the hatch body 3. If the hatch body 3 is in a fully closed state at this time, the head of the outwardly moved locking rod 51 will be inserted into the reserved lock hole 11 on the bracket 1, so that the locking mechanism 5 can quickly complete the locking between the hatch body 3 and the disinfection chamber from multiple directions. When it is necessary to open the hatch body 3, reverse-rotate the connecting sleeve 61 to drive the adjustment disc 62 to reverse, and the locking rod 51 can be pulled out of the lock hole 11.

[0039] In a further technical solution of the present invention, the anti - detachment and limit component 8 includes a cross - bar 81 elastically and slidably connected to the bottom of the inner cavity 31. A slider is fixedly connected to the bottom of the cross - bar 81. A chute is horizontally opened at the bottom of the inner cavity 31, and a top spring that abuts against the slider is installed in the chute. One end of the cross - bar 81 abuts against the outer wall of the observation pipe 4. A number of annularly distributed limit protrusions 44 are provided on the outer wall of the observation pipe 4. A through - slot 82 is horizontally opened at the other end of the cross - bar 81. An elastic cover member 9 is inserted through the bottom of the hatch body 3. The elastic cover member 9 covers the openings 71 at both ends of the biological indicator storage tube 7. One side of the inner wall of the through - slot 82 is fixedly connected with a plug - in block 83 that is in plug - in cooperation with the elastic cover member 9. Specifically, the number of limit protrusions 44 on the outer wall of the observation pipe 4 can cooperate with the cross - bar 81. When the cross - bar 81 abuts against the outer wall of the observation pipe 4 under the action of the top spring, its end will be in the depression between two adjacent limit protrusions 44, restricting the axial movement of the observation pipe 4 and preventing it from easily deflecting and shaking. At the same time, the elastic cover member 9 can cover the openings 71 at both ends of the biological indicator storage tube 7 under the action of elastic force. Moreover, the plug - in block 83 in the through - slot 82 forms a plug - in cooperation with the elastic cover member 9. When the cross - bar 81 abuts against the inner wall of the observation pipe 4, the plug - in block 83 and the elastic cover member 9 are separated. When the pipe is twisted so that the limit protrusions 44 abut against the cross - bar 81, the cross - bar 81 is forced to move outwards, causing the plug - in block 83 to be inserted into the elastic cover member 9. That is to say, when the hatch body 3 is opened, the elastic cover member 9 can be directly pulled to open the openings 71 at both ends of the biological indicator storage tube 7, thus facilitating the storage of the biological indicator. After releasing the elastic cover member 9, it will cover the opening 71 again under the action of elastic force. When the hatch body 3 is closed, the observation pipe 4 can be twisted to push the cross - bar 81 through the limit protrusions 44, so that the plug - in block 83 on the cross - bar 81 is inserted into the elastic cover member 9, avoiding the shaking and deviation of the elastic cover member 9 caused by the vibration generated during the medical waste treatment process and preventing the biological indicator from falling into the disinfection chamber, improving the stability and durability of the entire structure.

[0040] In a further technical solution of the present invention, the elastic cover member 9 includes a connecting frame 91. At both ends of the bottom of the connecting frame 91, anti-detachment end caps 92 matching the opening 71 are respectively fixedly connected. The top of the connecting frame 91 penetrates through the through groove 82 and is fixedly connected with a top plate 93 above the cross bar 81. The top of the top plate 93 abuts against the locking rod 51. An abutting pressure plate 94 is elastically connected to the bottom of the top plate 93. The abutting pressure plate 94 and the top plate 93 are connected by a connecting spring. The abutting pressure plate 94 is in contact with the top of the cross bar 81. A jack for inserting the insertion block 83 is horizontally opened on the connecting frame 91. Specifically, under the action of the abutting pressure plate 94, the top surface of the top plate 93 and the bottom of the locking rod 51 are in close contact. When the two are in contact, the anti-detachment end caps 92 on the connecting frame 91 just cover the openings 71 on both sides of the biological indicator storage tube 7. At this time, when the connecting frame 91 is pulled downward, the anti-detachment end caps 92 can move downward from the opening 71. After the openings 71 on both sides are opened, a biological indicator can be inserted through one of the openings 71. Then, the connecting frame 91 is released, and it automatically resets and moves upward under the elastic force of the abutting pressure plate 94, quickly covering the opening 71, preventing the biological indicator from falling during the process of the hatch cover body 3 flipping and closing, and also making the jack on the connecting frame 91 at the same horizontal line where the insertion block 83 can be smoothly inserted. When the cross bar 81 moves outward, the height of the connecting frame 91 is locked by the insertion block 83 on the cross bar 81, further ensuring the reliable closing of the openings 71 at both ends of the biological indicator storage tube 7.

[0041] In a further technical solution of the present invention, a wedge-shaped top block 84 is fixedly connected to the top of the cross bar 81. A limit clamping block 53 that abuts and cooperates with the wedge-shaped top block 84 is movably embedded at the bottom of the anti-deviation frame 52. A clamping groove 54 adapted to the limit clamping block 53 is opened at the bottom of the locking rod 51. Specifically, after the hatch cover body 3 is completely closed and the locking mechanism 5 completes the locking action, if one end of the cross bar 81 abuts against the observation pipeline 4, the positions of the wedge-shaped top block 84 and the limit clamping block 53 will be offset from each other. At this time, a part of the limit clamping block 53 protrudes from the bottom of the anti-deviation frame 52 under the action of gravity. When the cross bar 81 moves outward with the wedge-shaped top block 84, the wedge-shaped top block 84 will gradually lift the limit clamping block 53 until the wedge-shaped top block 84 supports the limit clamping block 53 from below and inserts it into the corresponding clamping groove 54 on the locking rod 51, performing clamping and limiting on the locking rod 51 that plays a role in locking the hatch cover, ensuring the locking strength. At the same time, if the locking rod 51 does not move completely to the designated position for complete locking, the positions of the clamping groove 54 and the limit clamping block 53 will deviate. At this time, the staff can timely discover whether it is completely locked by further locking the locking rod 51, reducing relevant safety hazards.

[0042] In a further technical solution of the present invention, a plugging rotating rod 32 is rotatably plugged at the top of the hatch body 3. A docking groove 56 matching the bottom of the plugging rotating rod 32 is formed at the top of the docking transmission rod 55. A plurality of cleaning scraping arms 33 for cleaning the transparent panel 43 at the bottom of the observation pipeline 4 are rotatably installed at the bottom of the hatch body 3, and the initial installation angles of the cleaning scraping arms 33 are distributed in an arithmetic progression. An adjusting ring 66 respectively in transmission connection with the docking transmission rod 55 and the cleaning scraping arms 33 is rotatably installed at the bottom of the adjusting disc 62. A transmission gear 57 is fixedly connected to the bottom of the docking transmission rod 55, and a driven gear 36 is installed at the top of the cleaning scraping arm 33. The transmission gear 57 and the driven gear 36 are respectively meshed and transmitted with the inner wall of the adjusting ring 66. Specifically, when the locking rod 51 does not move outwards to lock the hatch body 3, the positions of the docking transmission rod 55 and the plugging rotating rod 32 are staggered from each other. The docking transmission rod 55 is closer to the observation pipeline 4 at the center of the hatch body 3 than the plugging rotating rod 32. After the locking rod 51 moves outwards and is inserted into the lock hole 11 on the bracket 1, the docking transmission rod 55 is exactly below the plugging rotating rod 32, and the transmission gear 57 at the bottom of the docking transmission rod 55 is also meshed with the internal teeth of the adjusting ring 66. At this time, only need to align the bottom of the plugging rotating rod 32 with the docking groove 56 on the plugging rotating rod 32, and then rotate the plugging rotating rod 32 to drive the adjusting ring 66 to rotate, thereby driving the plurality of cleaning scraping arms 33 to rotate synchronously to clean the transparent panel 43 at the bottom of the observation channel, avoiding sundries from affecting the accuracy of observation. Since the initial angles of the cleaning scraping arms 33 are different, they will not affect each other during the synchronous rotation process, and further improve the cleaning efficiency.

[0043] In a further technical solution of the present invention, a cushion ring 67 is fixedly connected to the top of the connecting sleeve 61. The top of the cushion ring 67 is in contact with the bottom of the cross beam 2.

Specifically, the cushion ring 67 can form a tight contact surface with the bottom of the cross beam 2 to ensure the stability of the connecting sleeve 61. At the same time, the pressing spring 68 at the bottom of the cushion ring 67 tightly abuts against the hatch body 3. In this way, the connecting sleeve 61 will not easily deflect axially, avoiding the locking mechanism 5 being in a loose state during the opening and closing process of the hatch body 3.

[0044] In a further technical solution of the present invention, a medium injection joint 34 is installed at the top of the hatch body 3, and a conveying hose 35 is installed at the top of the medium injection joint 34. Specifically, the medium injection joint 34. The function of this joint is to allow external media (such as gas, liquid, etc.) to be safely and effectively injected into the disinfection chamber space enclosed by the hatch body 3. In order to ensure the smooth and stable flow of the medium, a conveying hose 35 is further connected to the top of the medium injection joint 34, which can adapt to various complex medium conveying environments.
