Description

Technical Field

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

[0002] Medical disinfection equipment and disinfection methods are mainly used to kill or remove pathogenic microorganisms on medical devices, the diagnosis and treatment environment, and medical supplies, so as to ensure medical safety and reduce the occurrence of hospital infections. Common medical disinfection equipment includes steam sterilizers, ultraviolet disinfection devices, 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 using disinfectants such as sodium hypochlorite and hydrogen peroxide). A steam sterilizer is a disinfection and sterilization equipment that uses saturated steam under pressure 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. Due to the advantages of rapid heating, thorough sterilization, safety and reliability, etc., steam sterilizers are widely used in the fields of medical and health, scientific research, etc., and are the main sterilization methods for high-temperature-resistant items such as surgical instruments, dressings, glassware, and culture media.

[0003] In the prior art, for example, a high-efficiency sterilization pot with the publication number of CN221617981U includes a sterilization pot body and a sterilization rack. The sterilization rack is movably arranged in the sterilization pot. The sterilization rack includes a top plate, a bottom plate, a screw rod, a material tray and a threaded sleeve. A screw rod is arranged between the top plate and the bottom plate. Through the settings of the top plate, the bottom plate, the screw rod and the material tray, materials can be stored in layers, increasing the contact area between the materials and high-temperature steam, improving the sterilization efficiency, and by rotating the threaded sleeve on the material tray, the height of the material tray can be easily adjusted to adapt to the placement requirements of materials with different heights and different sizes, saving space and greatly improving the utilization rate of space.

[0004] In order to solve the uniformity of product sterilization, the prior art adopts a layered storage method to increase the contact area between materials and high-temperature steam. However, in the actual use process, the existing sterilization rack lacks a protective structure, and when the traditional sterilization pot performs steam sterilization and disinfection on products, water vapor is easy to condense into water droplets on its inner top wall and drip into the items, causing secondary pollution of the items and reducing the disinfection effect of the medical disinfection equipment.

Detailed Implementation Manner

[0041] In order to clearly and completely describe the objectives and technical solutions of the present invention and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0042] Example 1. Please refer to Figure 1-16 , the present invention provides a technical solution: a medical disinfection device, including a medical sterilizer body 1. A steam generator 11 is provided at the lower end of the medical sterilizer body 1. A pot cover 13 is movably installed at the upper end of the medical sterilizer body 1. A sterilization inner pot 12 is fixedly connected inside the medical sterilizer body 1. A water condensation collection cylinder 120 is provided directly below the sterilization inner pot 12. A medical appliance placement mechanism 2 is provided inside the sterilization inner pot 12. The medical appliance placement mechanism 2 includes a support ring plate 21, a limit annular plate 22, a first annular plate 23, a driving rotary gear cylinder 24, and an anti-pollution ring 25. The inner ring surface of the anti-pollution ring 25 is fixedly connected to the upper end of the driving rotary gear cylinder 24. The support ring plate 21 is fixedly installed between the sterilization inner pot 12 and the water condensation collection cylinder 120. A classification storage frame 26 is movably connected between the first annular plate 23 and the anti-pollution ring 25. A steam anti-backflow mechanism 3 is provided at the center of the sterilization inner pot 12. The steam anti-backflow mechanism 3 includes a hollow fixed cylinder 31, a steam through pipe 32, and a conical lifting column 33. An annular cavity is formed between the inner surface of the hollow fixed cylinder 31 and the outer surface of the steam through pipe 32; A pot cover water collection assembly is provided inside the upper end of the medical sterilizer body 1. The pot cover water collection assembly includes a diversion ring 131 and a storage tank plate 132. The upper ends of the storage tank plate 132 and the diversion ring 131 are fixedly connected to the inner cavity top surface of the medical sterilizer body 1. A seepage groove is formed between the lower end of the diversion ring 131 and the storage tank plate 132. A discharge pipe is connected through the inner wall of the storage tank plate 132 and extends to the outside of the medical sterilizer body 1. A solenoid valve is provided inside the discharge pipe; The storage tank plate 132 here is used to store the water droplets generated on the pot cover 13, avoiding the situation that the steam condensed from the high temperature on the pot cover 13 drops onto the medical items and causes secondary pollution.

[0043] In this embodiment, through the optimization of the overall structure of the medical appliance placement mechanism 2, multi-layer classification storage of medical products can be carried out, and it can be expanded and retracted after steam sterilization, which is convenient for taking and placing, saves storage space and improves space utilization rate. Moreover, through the design of the steam anti-counterflow mechanism 3, while ensuring uniform distribution of steam at the bottom of the sterilization inner pot 12, the steam is extended upward to expand the sterilization area. And through the setting of the steam anti-counterflow mechanism 3, it is possible to avoid the reverse flow of condensed water droplets through the steam outlet holes, causing secondary pollution of the sterilized products and the steam pipe 32.

[0044] Embodiment 2. Refer to the attached Figure 1-16 , on the basis of Embodiment 1, in order to achieve layered storage of medical appliances in the future and improve space utilization rate, this embodiment also proposes that the lower surface of the limiting annular plate 22 is fixedly connected to the upper surface of the support ring plate 21, and the inner surface of the upper side of the limiting annular plate 22 is movably connected to the outer ring surface of the annular plate 1 23. An embedded block 231 is fixedly connected to the outer ring surface of the annular plate 1 23. The embedded block 231 and the annular plate 1 23 are integrally formed structures. The outer surface of the embedded block 231 is movably embedded in the inner wall of the embedded groove 220. A socket column 230 is fixedly connected to the inner surface of the center of the annular plate 1 23. The socket column 230 and the annular plate 1 23 are integrally formed structures. The inner surface of the socket column 230 is movably connected to a socket inner cylinder 27. The upper end of the socket inner cylinder 27 protrudes above the socket column 230. The lower end of the socket inner cylinder 27 is fixedly connected to a rotating ring 271. The rotating ring 271 and the socket inner cylinder 27 are integrally formed structures. The upper surface of the rotating ring 271 is movably connected to the lower surface of the annular plate 1 23. The upper surface of the socket 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 by a hollow cylindrical structure and a flat gear disk. The inner surface of the hollow cylindrical structure is movably connected to the outer surface of the socket column 230. An incomplete gear 241 meshes and rotates on the outer surface of the flat gear disk. A shaft rod 242 is fixedly connected to the inner wall of the incomplete gear 241. The lower end of the shaft rod 242 is rotatably connected to the inner wall of the annular plate 1 23. The outer surface of the upper end of the shaft rod 242 is fixedly connected to the inner wall of the lower end of the classification storage frame 26.

[0045] In this embodiment, with the support ring plate 21 as the bottom support structure and the limiting annular plate 22 installed above the support ring plate 21, when the entire medical appliance placement mechanism 2 is placed, the bottom of the annular plate 1 23 is aligned with the upper ring surface of the limiting annular plate 22 and is limited by the upper ring surface of the limiting annular plate 22. At this time, the embedded block 231 is aligned with the embedded groove 220 for embedding. As Figures 3-5 shown, after the annular plate 1 23 is embedded, at this time, by rotating the socket inner cylinder 27, the rotating ring 271 is driven to perform axial movement at the bottom of the annular plate 1 23. It should be noted that as Figures 7-8As shown, when the annular plate 1-23 and the limiting annular plate 22 are fitted 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;

[0046] It should be noted that the active rotating toothed cylinder 24 is integrally formed by a hollow cylindrical structure and a planar toothed disc, and the anti-fouling ring 25 is fixedly connected to the active rotating toothed cylinder 24. Before or after the medical appliance placing mechanism 2 is placed entirely inside the medical sterilizer body 1, the anti-fouling ring 25 and the active rotating toothed cylinder 24 as a whole can be manually rotated so that the tooth surface of the planar toothed disc meshes with the incomplete gear 241. Under the action of adaptive engagement, the incomplete gear 241 drives the connected classification storage frame 26 to swing. In this way, by rotating the active rotating toothed cylinder 24, the swinging states of multiple groups of classification storage frames 26 are adjusted. When the classification storage frame 26 is fully retracted to the inner sides of the annular plate 1-23 and the anti-fouling ring 25, it does not affect the taking and placing between the medical appliance placing mechanism 2 and the medical sterilizer body 1. When the classification storage frame 26 swings to the unfolded state, it is convenient for medical staff to quickly and conveniently take and place medical appliances, improving space utilization.

[0047] Embodiment 3, referring to the attached Figure 1-16 , on the basis of Embodiment 2, this embodiment adds a contraction component and a locking component: a limiting arc-shaped groove 2710 is formed on the inner wall of the rotating ring 271, and a contraction component is arranged inside the limiting arc-shaped groove 2710. The contraction component includes a locking block 2711. The outer surface of the locking block 2711 is slidably connected to the lower surface of the rotating ring 271. The upper end of the locking block 2711 is fixedly connected with a limiting column 27110, and the outer surface of the limiting column 27110 is movably connected to the inner surface of the limiting arc-shaped groove 2710; a parallel groove plate 221 is fixedly connected to the inner bottom surface of the limiting annular plate 22, a locking groove 2201 is formed on the outer ring inner wall of the limiting annular plate 22, the inner surface of the parallel groove plate 221 is slidably connected to the outer surface of the locking block 2711, and a locking component is arranged at the outer end of the locking block 2711. The locking component includes an elastic extrusion clamp block 2712, and the elastic extrusion clamp block 2712 is fixedly installed inside the locking groove 2201. Two groups of elastic extrusion clamp blocks 2712 are arranged inside each locking groove 2201, and the two groups of elastic extrusion clamp blocks 2712 are symmetrically distributed about the horizontal central axis of the locking groove 2201. The inner surface of the elastic extrusion clamp block 2712 is movably abutted against the outer surface of the locking block 2711, and an abutting block 2713 is fixedly connected to the inside of the elastic extrusion clamp block 2712. The abutting block 2713 has an "A"-shaped block structure;

[0048] In this embodiment, as Figures 4-8As 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 5 As 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.

[0049] 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.

[0050] In this embodiment, if Figures 13-14As shown in the figure, with the hollow fixed cylinder 31 as the support, the hollow fixed cylinder 31 is connected to the support ring plate 21. The steam pipe 32 extends into 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 discharge pipe 310 for collecting and discharging water droplets. It should be noted that the top of the steam pipe 32 is connected with a steam discharge cylinder 321. A flow cavity is formed between the steam discharge cylinder 321 and the conical lifting column 33. It should be noted that the diameter of the steam nozzle 323 is smaller than that of the hollow fixed cylinder 31. Such a setting is to ensure that the water droplets dripping from the top of the steam nozzle 323 can smoothly fall into the upper concave structure of the support socket 311. Such an inclined concave design ensures that the water droplets can more smoothly enter the annular cavity formed by the hollow fixed cylinder 31 and the steam pipe 32 through the water collecting tank 312, avoiding the water droplets flowing back into the steam pipe 32 and causing secondary pollution of the steam. When the condensed water droplets enter the water condensation collection cylinder 120, they can be discharged through the drain valve to avoid the accumulation of sewage and the formation of scale.

[0051] Embodiment 5. Refer to the attached Figure 1-16 , on the basis of Embodiment 4, in order to realize the uniform ejection of steam, this embodiment also proposes that: the outer surface of the upper side of the steam discharge cylinder 321 is threadedly connected with a threaded ring 322. The outer ring surface of the threaded ring 322 is fixedly connected with a steam nozzle 323. The steam nozzle 323 is integrally in the shape of a frustum of a cone. There is an inclined surface on the upper side of the steam nozzle 323, and exhaust holes II 3230 are opened on the inner wall of the inclined surface; the conical lifting column 33 is movably installed inside the steam discharge cylinder 321. A flow cavity is formed between the conical lifting column 33 and the inner wall of the steam discharge cylinder 321. The upper end of the flow cavity communicates with the exhaust hole I 3210; the conical lifting column 33 is in the shape of a frustum of a cone with a narrow bottom and a wide top. A connecting ring 331 is fixedly connected to the outer surface of the upper side of the conical lifting column 33. A contact elastic wire 332 is fixedly connected to the upper surface of the connecting ring 331. The other end of the contact elastic wire 332 is fixedly connected to the top surface of the inner cavity of the steam nozzle 323;

[0052] In this embodiment, as Figure 14As shown, high-pressure steam impacts the bottom of the conical lifting column 33 through the outlet of the steam pipe 32. At this time, the conical lifting column 33 moves upward, and a flow cavity is formed between the conical lifting column 33 and the steam discharge cylinder 321. The steam enters the top of the steam discharge cylinder 321 through the flow cavity and then is ejected through a plurality of sets of exhaust holes one 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 through a plurality of sets of exhaust holes two 3230; 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 lifted by the high-pressure steam at the bottom, prevent the conical lifting column 33 from deflecting during lifting and lowering, and utilize the reverse elastic force of the abutting elastic wire 332 to satisfy the automatic reset of the conical lifting column 33 when not impacted by steam for lifting, realizing the automatic sealing of the outlet of the steam pipe 32.

[0053] Embodiment Six. Refer to the attached Figure 1-16 , on the basis of Embodiment Five, the present invention also provides a disinfection method for a medical disinfection device, including the following steps:

[0056] Step 3: Rotate the top of the sleeved inner cylinder 27, and through the cooperation of the contraction component and the locking component, lock the entire annular plate one 23. After locking is completed, cover the pot lid 13;

[0057] Step 4: Trigger the steam generator 11. Use the steam pipe 32 to extend into the interior of the steam generator 11 to achieve the transmission of high-temperature steam. The high-pressure steam impacts the bottom of the conical lifting column 33 through the outlet of the steam pipe 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 cylinder 321. The steam enters the top of the steam discharge cylinder 321 through the circulation cavity, and then is ejected through a plurality of rows of exhaust holes one 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 through a plurality of rows of exhaust holes two 3230;

[0058] Step 5: After the sterilization and disinfection of medical appliances are completed, open the pot lid 13 and move it slightly to one side. After part of the high-temperature steam is discharged, fully open the pot lid 13, and then lift out the entire first annular plate 23. Then, rotate the active rotating gear cylinder 24 to make a plurality of classified storage frames 26 extend out, and finally take out the medical appliances for sterile storage.
