Description

Technical Field

[0001] The invention relates to the technical field of medical disinfection equipment, in particular to medical disinfection equipment and a disinfection method. Background Art

[0002] Medical disinfection equipment and methods are mainly used to kill or remove pathogenic microorganisms on medical devices, diagnosis and treatment environments and medical supplies to ensure medical safety and reduce the occurrence of hospital infections. Common medical disinfection equipment includes steam sterilizers, ultraviolet disinfectors, chemical disinfection cabinets, etc., and disinfection methods mainly include physical disinfection methods (such as high-temperature steam disinfection, radiation disinfection, etc.) and chemical disinfection methods (such as the use of sodium hypochlorite, hydrogen peroxide and other disinfectants). Steam sterilizer is a disinfection and sterilization equipment that uses pressurized saturated steam to quickly and reliably sterilize items. It heats water through a steam generator to form high-pressure steam, and releases a large amount of latent heat in the sterilization chamber, thereby thoroughly sterilizing items with bacteria. Since steam sterilizers have the advantages of rapid heating, thorough sterilization, safety and reliability, they are widely used in medical and health, scientific research and other fields. It is the main sterilization method for high-temperature resistant items such as surgical instruments, dressings, glassware, culture media, etc.

[0003] In the prior art, there is a high-efficiency autoclave with publication number CN221617981U, which includes an autoclave body and a sterilization rack, wherein the autoclave is movably provided with a sterilization rack, and the sterilization rack includes a top plate, a bottom plate, a screw, a material tray and a threaded sleeve, and a screw is provided between the top plate and the bottom plate. The materials can be stored in layers by the arrangement of the top plate, the bottom plate, the screw and the material tray, thereby increasing the contact area between the materials and the high-temperature steam and improving the sterilization efficiency, and by rotating the threaded sleeve on the material tray, the height of the material tray can be easily adjusted, thereby adapting to the placement requirements of materials of different heights and sizes, saving space, and greatly improving the utilization rate of space.

[0004] In order to solve the problem of uniformity in product sterilization, the existing technology adopts a layered storage method to increase the contact area between materials and high-temperature steam.

[0022] Embodiment 2, refer to the attached Figure 1-16On the basis of the first embodiment, in the future, the medical appliances can be stored in layers to improve the space utilization. The present embodiment further proposes that: the lower surface of the limiting annular plate 22 is fixedly connected to the upper surface of the supporting annular plate 21, the upper inner surface of the limiting annular plate 22 is movably connected to the outer ring surface of the annular plate 23, the outer ring surface of the annular plate 23 is fixedly connected with an insert 231, the insert 231 and the annular plate 23 are an integrally formed structure, and the outer surface of the insert 231 is movably embedded with the inner wall of the embedding groove 220; the central inner surface of the annular plate 23 is fixedly connected with a sleeve column 230, the sleeve column 230 and the annular plate 23 are an integrally formed structure, the inner surface of the sleeve column 230 is movably connected with a sleeve inner cylinder 27, and the upper end of the sleeve inner cylinder 27 is higher than the sleeve column 2 30, a rotating ring 271 is fixedly connected to the lower end of the sleeve inner cylinder 27; the rotating ring 271 and the sleeve inner cylinder 27 are an integrally formed structure, the upper side surface of the rotating ring 271 is movably connected to the lower surface of the annular plate 23, the upper side surface of the sleeve inner cylinder 27 is movably connected to the lower surface of the active rotating gear cylinder 24, the active rotating gear cylinder 24 is integrally formed with a hollow cylindrical structure and a plane gear disk, the inner surface of the hollow cylindrical structure is movably connected to the outer surface of the sleeve column 230; an incomplete gear 241 is meshed and rotated on the outer surface of the plane gear disk, and a shaft 242 is fixedly connected to the inner wall of the incomplete gear 241, the lower end of the shaft 242 is rotatably connected to the inner wall of the annular plate 23, and the upper end outer surface of the shaft 242 is fixedly connected to the lower end inner wall of the classification storage frame 26; In this embodiment, the support ring plate 21 is used as the bottom support structure, and the limiting ring plate 22 is installed above the support ring plate 21. When the medical device placement mechanism 2 is placed as a whole, the bottom of the ring plate 23 is aligned with the upper ring surface of the limiting ring plate 22 and is limited by the upper side ring surface of the limiting ring plate 22. At this time, the insert 231 is aligned with the embedding groove 220 for embedding. Figure 3-Figure 5 As shown, after the annular plate 23 is embedded, the inner cylinder 27 is rotated to drive the rotating ring 271 to move axially at the bottom of the annular plate 23; it is worth noting that, as Figure 7-Figure 8 As shown, when the annular plate 23 and the limiting annular plate 22 are embedded in place, the locking block 2711 at the bottom of the rotating ring 271 is just aligned with the inner side of the parallel groove plate 221, so that the horizontal movement of the locking block 2711 is limited by the parallel groove plate 221; It should be noted that the active rotating gear cylinder 24 is formed by a hollow cylindrical structure and a flat gear disk, and the anti-fouling ring 25 is fixedly connected to the active rotating gear cylinder 24. Before the medical tool placement mechanism 2 is placed as a whole inside the medical sterilization pot body 1 or after it is taken out, the anti-fouling ring 25 and the active rotating gear cylinder 24 can be manually rotated as a whole, so that the tooth surface of the flat gear disk and the incomplete gear 241 are meshed with each other. Under the action of the adaptive bite, the incomplete gear 241 drives the connected classification storage frame 26 to swing. In this way, the swinging state of multiple groups of classification storage frames 26 can be adjusted by rotating the active rotating gear cylinder 24. When the classification storage frame 26 is completely retracted to the inner side of the annular plate 23 and the anti-fouling ring 25, it does not affect the placement of the medical tool placement mechanism 2 and the medical sterilization pot body 1. When the classification storage frame 26 swings to the expanded state, it can be convenient for medical staff to quickly and conveniently take and place medical tools, thereby improving space utilization.

[0023] Embodiment 3, refer to the attached Figure 1-16 On the basis of the second embodiment, this embodiment adds a contraction component and a locking component: a limited arc groove 2710 is provided on the inner wall of the rotating ring 271, and a contraction component is provided on the inner side of the limited arc groove 2710, and the contraction component includes a locking block 2711, and the outer surface of the locking block 2711 is slidably connected to the lower surface of the rotating ring 271, and the upper end of the locking block 2711 is fixedly connected to the limited column 27110, and the outer surface of the limited column 27110 is movably connected to the inner surface of the limited arc groove 2710; a parallel groove plate 221 is fixedly connected to the inner bottom surface of the limited annular plate 22, and a locking groove 2201 is provided on the inner wall of the outer ring of the limited annular plate 22, and the parallel groove plate 221 is fixedly connected to the inner bottom surface of the limited annular plate 22, and a locking groove 2201 is provided on the inner wall of the outer ring of the limited annular plate 22. The inner surface of 21 is slidably connected with the outer surface of the locking block 2711, and a locking assembly is arranged at one end of the outer side of the locking block 2711, and the locking assembly includes an elastic extrusion clamping block 2712, and the elastic extrusion clamping block 2712 is fixedly installed inside the locking groove 2201, and two groups of elastic extrusion clamping blocks 2712 are arranged inside each group of locking grooves 2201, and the two groups of elastic extrusion clamping blocks 2712 are mirror-distributed about the horizontal central axis of the locking groove 2201, and the inner surface of the elastic extrusion clamping block 2712 is movably abutted with the outer surface of the locking block 2711, and the inner side of the elastic extrusion clamping block 2712 is fixedly connected with an abutting block 2713, and the abutting block 2713 is an "A"-shaped block structure; In this embodiment, if Figure 4-Figure 8 As shown in the figure, after the embedding block 231 and the embedding groove 220 are initially engaged and limited, in order to ensure the stability of the medical tool placement mechanism 2 as a whole inside the medical sterilization pot body 1, the annular plate 23 and the limiting annular plate 22 are further locked. Specifically, the operator rotates the top of the sleeve inner cylinder 27 by hand. Since the sleeve inner cylinder 27 is higher than one end of the sleeve column 230, the sleeve inner cylinder 27 can be directly rotated at this time. When the sleeve inner cylinder 27 is rotated, the rotating ring 271 rotates synchronously, as shown in FIG. Figure 5As shown, the locking block 2711 is now fitted with the parallel groove plate 221, and the limiting arc groove 2710 drives the limiting column 27110 to move, thereby making the two sets of locking blocks 2711 relatively movable. At this time, one end of the locking block 2711 enters between the locking grooves 2201. It is worth noting that Figure 6 As shown, at this time, both sides of the locking block 2711 resist the inner curved surface of the elastic extrusion clamp block 2712, so that the elastic extrusion clamp block 2712 and the abutment block 2713 are elastically squeezed. After the locking block 2711 stops moving, the elastic extrusion clamp block 2712 and the abutment block 2713 generate reverse elastic force to clamp the locking block 2711 to prevent the locking block 2711 from moving. In this way, the overall locking of the annular plate 23 is achieved, further enhancing the stability of the medical device during the high-temperature steam sterilization process.

[0024] Embodiment 4, refer to the attached Figure 1-16 On the basis of the third embodiment, in order to make the high-temperature steam evenly distributed in the inner cavity of the sterilizing inner pot 12, the present embodiment further proposes that: the outer surface of the hollow fixed cylinder 31 is movably connected to the inner surface of the sleeve inner cylinder 27, the outer surface of the lower end of the hollow fixed cylinder 31 is fixedly connected to the central inner wall of the support ring plate 21, the lower end of the hollow fixed cylinder 31 is connected with a sewage pipe 310, the sewage pipe 310 extends to the inside of the hydrocondensate collection cylinder 120, the lower end of the steam through pipe 32 passes through the bottom of the hollow fixed cylinder 31 and The steam pipe 32 extends to the interior of the steam generator 11. The upper end of the steam passage 32 is connected with a steam exhaust tube 321. The upper inner wall of the steam exhaust tube 321 is provided with a steam exhaust hole 3210. The upper inner wall of the hollow fixed tube 31 is fixedly connected with a support sleeve 311. The upper end of the support sleeve 311 is set as a concave annular structure. The inner wall of the support sleeve 311 is provided with a water collecting groove 312. The inner ring surface of the support sleeve 311 is fixedly connected with the outer surface of the steam exhaust tube 321. In this embodiment, if Figure 13-14As shown, the hollow fixed cylinder 31 is used as a support, the hollow fixed cylinder 31 is connected to the support ring plate 21, and the steam pipe 32 is extended to the inside of the steam generator 11 to realize the transmission of high-temperature steam. The bottom of the hollow fixed cylinder 31 is connected with a sewage pipe 310 for collecting water droplets. It is worth noting that the top of the steam pipe 32 is connected with a steam discharge cylinder 321, and a flow cavity is formed between the steam discharge cylinder 321 and the conical jacking column 33. It should be noted that the diameter of the steam nozzle 323 is smaller than that of the hollow fixed cylinder. The diameter of the cylinder 31 is set in this way to ensure that the water droplets dripping from the top of the steam nozzle 323 can smoothly drip into the upper concave structure of the support sleeve 311. Such an inclined concave design ensures that the water droplets can more smoothly pass through the water collecting tank 312 into the annular cavity formed by the hollow fixed cylinder 31 and the steam through pipe 32, avoiding the generation of water droplets backflowing into the steam through pipe 32 and causing secondary contamination of the steam. When the condensed water droplets enter the condensate collection cylinder 120, they can be discharged through the drain valve to avoid the accumulation of sewage and the formation of scale.

[0025] Embodiment 5, refer to the attached Figure 1-16 On the basis of the fourth embodiment, in order to realize uniform steam ejection, the present embodiment further proposes: a threaded ring 322 is threadedly connected to the upper outer surface of the steam discharge tube 321, a steam nozzle 323 is fixedly connected to the outer ring surface of the threaded ring 322, the steam nozzle 323 is a conical table structure as a whole, an inclined surface is arranged on the upper side of the steam nozzle 323, and a second steam exhaust hole 3230 is opened on the inner wall of the inclined surface; the conical lifting column 33 is movably mounted on the steam discharge tube On the inner side of 321, a flow cavity is formed between the conical lifting column 33 and the inner wall of the steam discharge tube 321, and the upper end of the flow cavity is mutually connected with the exhaust hole 3210; the conical lifting column 33 is a conical table-like structure with a narrow bottom and a wide top, and a connecting ring 331 is fixedly connected to the upper outer surface of the conical lifting column 33, and an abutting elastic wire 332 is fixedly connected to the upper surface of the connecting ring 331, and the other end of the abutting elastic wire 332 is fixedly connected to the top surface of the inner cavity of the steam nozzle 323; In this embodiment, if Fig.14As shown, high-pressure steam impacts the bottom of the conical lifting column 33 through the output port of the steam passage 32. At this time, the conical lifting column 33 moves upward, and a circulation cavity is formed between the conical lifting column 33 and the steam discharge tube 321. The steam enters the top of the steam discharge tube 321 through the circulation cavity, and then is ejected through multiple groups of exhaust holes 1 3210 arranged in an array. At this time, the high-pressure steam enters the inner side of the steam nozzle 323 for buffering, and then is discharged in all directions through multiple groups of exhaust holes 2 3230; and it should be noted that the mutual cooperation between the connecting ring 331 and the abutting elastic wire 332 can ensure the stable movement of the conical lifting column 33 when it is lifted by the bottom high-pressure steam, avoid the deflection of the conical lifting column 33 when it is lifted and lowered, and utilize the reverse elastic force of the abutting elastic wire 332 to meet the automatic reset of the conical lifting column 33 when it is not lifted by steam impact, thereby realizing the automatic blocking of the output port of the steam passage 32.

[0026] Embodiment 6, refer to the attached Figure 1-16 On the basis of the fifth embodiment, the present invention further provides a method for disinfecting medical disinfection equipment, comprising the following steps: Step 1: before placing the medical implement placement mechanism 2 as a whole inside the medical sterilization pot body 1, unfold multiple groups of classification storage frames 26 to place medical implements of different categories, rotate the anti-fouling ring 25 and the active rotating gear cylinder 24 as a whole, so that the tooth surface of the plane gear disk and the incomplete gear 241 are meshed with each other, and under the action of the adaptive bite, the incomplete gear 241 drives the connected classification storage frame 26 to be completely recovered between the annular plate 23 and the anti-fouling ring 25; Step 2: Place the medical implement placement mechanism 2 and the placed medical implements into the sterilization inner pot 12, align the bottom of the annular plate 23 with the upper annular surface of the limiting annular plate 22 and limit the position through the upper annular surface of the limiting annular plate 22. At the same time, the locking block 2711 is adapted and clamped with the parallel groove plate 221. Step 3: Rotate the top of the sleeve inner cylinder 27, and lock the annular plate 23 as a whole by cooperating with the contraction component and the locking component. After the locking is completed, cover the pot cover 13; Step 4, trigger the steam generator 11, and use the steam through pipe 32 to extend to the inside of the steam generator 11 to realize the transmission of high-temperature steam. The high-pressure steam impacts the bottom of the conical jacking column 33 through the output port of the steam through pipe 32. At this time, the conical jacking column 33 moves upward, and a flow cavity is formed between the conical jacking column 33 and the steam discharge tube 321. The steam enters the top of the steam discharge tube 321 through the flow cavity, and then sprays out through multiple groups of exhaust holes 1 3210 arranged in an array. At this time, the high-pressure steam enters the inner side of the steam nozzle 323 for buffering, and then passes through multiple groups of exhaust holes 2 3230 to be discharged; Step 5. After the sterilization of the medical instruments is completed, the pot cover 13 is opened and slightly moved to one side. After part of the high-temperature steam is discharged, the pot cover 13 is completely opened, and then the annular plate 23 is lifted out as a whole. Then, the active rotating gear cylinder 24 is rotated to extend multiple groups of classification storage frames 26, and finally the medical instruments are taken out for sterile storage.
