Description

Technical Field

[0001] This utility model relates to the technical field of sterilization cabinets, and in particular to an ampoule leak detection sterilization cabinet. Background Technology

[0002] Sterilization refers to the use of strong physical and chemical agents to permanently disable the growth and reproduction of all microorganisms, both inside and outside an object. Common sterilization methods include chemical sterilization, radiation sterilization, dry heat sterilization, moist heat sterilization, and filtration sterilization. Different methods are used depending on the specific needs; for example, moist heat sterilization is generally used for culture media sterilization, while filtration sterilization is used for air. The thoroughness of sterilization is limited by the sterilization time and the strength of the sterilizing agent. The resistance of microorganisms to sterilizing agents depends on the initial population density, the species, or the resistance conferred by the environment. Sterilization is a necessary condition for obtaining pure cultures and is an essential technology in the food and pharmaceutical industries.

[0003] The existing device places the ampoules inside a steam sterilizer and sterilizes them with steam. After sterilization, a pressure differential is used to monitor for any gaps in the ampoules. However, the fixed placement plate design of the existing device makes it inconvenient to remove the ampoules. Therefore, a lifting structure was designed to address the above-mentioned problems and facilitate the removal of the ampoules. Utility Model Content

[0004] The purpose of this invention is to provide an ampoule leak detection and sterilization cabinet to solve the problems mentioned in the background art.

[0005] The technical solution adopted in this utility model is:

Therefore, they should not be construed as limitations on this utility model.

[0025] In current technology, existing devices place ampoules inside a steam sterilizer to sterilize them with steam, and then monitor for gaps using a pressure differential environment after sterilization. However, the fixed placement plate design of existing devices makes it inconvenient to remove the ampoules.

[0026] As shown in the attached drawings, this utility model embodiment provides an ampoule leak detection and sterilization cabinet.

[0027] The device includes: a cover 12 on the top of the sterilizer body 11; a placement plate 13 disposed inside the sterilizer body 11; and a lifting assembly 2 disposed inside the sterilizer body 11. The lifting assembly 2 includes: a housing 21 whose bottom end is fixedly connected to the inner wall of the sterilizer body 11; a slot 22 formed on the outer wall of the housing 21; a vertical rod 23 whose bottom end is inserted into the interior of the housing 21 and whose outer wall is connected to one end of the placement plate 13, and whose top end is fixedly connected to the bottom of the cover 12; a locking block 24 whose one end penetrates the inner wall of the vertical rod 23 and is inserted into the slot 22; a crossbar 25 whose two ends both penetrate the locking block 24 and are fixedly connected to the inner wall of the vertical rod 23; a connecting rod 26 whose bottom end is rotatably connected to one end of the locking block 24; and a pull rod 27 whose bottom end penetrates the cover 12 and is inserted into the interior of the vertical rod 23 and rotatably connected to the top end of the connecting rod 26.

[0028] Specifically, the sterilizer body 11 is a key pharmaceutical equipment that integrates sterilization and leak detection functions. It is mainly used to ensure the sterility and sealing integrity of injections (especially water injections filled in ampoules), and is an indispensable part of safe drug production.

[0029] I. Sterilization Principle

[0030] The sterilization process usually employs saturated steam sterilization, which utilizes the property that saturated steam under high temperature and pressure releases a large amount of latent heat when condensing, so that the medicine in the ampoule quickly and evenly reaches the sterilization temperature and maintains it for a sufficient time, thereby killing all microorganisms, including heat-resistant bacterial spores.

[0031] II. Leak Test Principle

[0032] Leak detection is a crucial step in determining whether an ampoule is sealed tightly and whether there are any minor cracks. Its basic principle is based on pressure difference. Currently, the most mainstream and reliable methods are high-voltage discharge leak detection and colorimetric leak detection (vacuum decay method). Modern ampoule leak detection sterilization cabinets typically integrate the latter into the sterilization process.

[0033] When placing ampoules, insert the top of the ampoule into the hole on the placement plate 13, then pull the lever 27 to pull it out from inside the upright 23. This will cause the connecting rod 26 to rotate, making the locking block 24 slide inside the crossbar 25. This will cause the locking block 24 to retract into the upright 23 and disengage from the slot 22 on the housing 21, thus releasing the fixation on the upright 23. Then, insert the upright 23 into the housing 21 and place the placement plate 13 into the sterilizer body 11. Next, push the lever 27 downward to insert it into the upright 23, causing the connecting rod 26 to rotate. This will push the locking block 24 out from inside the upright 23 and insert it into the slot 22, completing the process of fixing the upright 23. Then, use the sterilizer body 11 to sterilize the surface of the ampoule and perform leak detection. The above principle can be used as a reference.

[0034] In some embodiments, one end of the card block 24 is designed with a bevel.

[0035] The inclined surface design allows the locking block 24 to retract into the interior of the upright 23 when the upright 23 is pulled upward, eliminating the need for manual control of the pull rod 27.

[0036] In some embodiments, the lifting assembly 2 further includes a pull plate 271 fixedly disposed on the top of the pull rod 27.

[0037] The design of the pull plate 271 makes it easy to grip and allows the pull rod 27 to move up and down more easily.

[0038] In some embodiments, the lifting assembly 2 further includes: a spring 28 sleeved on the outside of the crossbar 25, and fixedly connected at both ends to the locking block 24.

[0039] The design of spring 28 allows it to use its elasticity to push the locking blocks 24 away from each other on the outside of the crossbar 25, so that they can be stably engaged with the locking slot 22.

[0040] In some embodiments, the lifting assembly 2 further includes a handle 29 fixedly disposed on the top of the cover 12.

[0041] The handle 29 is designed so that when gripping the pull plate 271, the lid 12 can be moved upward while pulling the lever 27 upward, making it easier to grip.

[0042] In some embodiments, a fixing component 3 is provided on the outer side of the upright 23. The fixing component 3 includes: an insertion hole 31 opened at the top of the placement plate 13; a frame 32 fixedly disposed on the outer side wall of the upright 23; a bottom end of an insertion rod 33 inserted into the interior of the frame 32; a top plate 34 fixedly disposed at the top of the insertion rod 33; and a second spring 35 sleeved on the outer side of the insertion rod 33, with both ends fixedly connected to the top plate 34 and the frame 32 respectively.

[0043] The different heights of the ampoules require adjustment of the spacing between the placement plates 13. This can be done by pulling the top plate 34, which stretches the second spring 35 and disengages the insertion rod 33 from the insertion hole 31 on the placement plate 13, thus releasing the fixation of the placement plate 13. Then, one end of the placement plate 13 can be pulled out from the inside of the frame 32 to complete the disassembly. Subsequently, it can be inserted into the inside of another frame 32 (while pulling the top plate 34 in the same way). Then, the top plate 34 is released, and the second spring 35 retracts, allowing the insertion rod 33 to engage with the insertion hole 31, thereby fixing the placement plate 13.

[0044] In some embodiments, two sets of the insertion holes 31, the insertion rods 33, and the top plate 34 are symmetrically arranged.

[0045] It features two sets of additional connection points to enhance stability.

[0046] In some embodiments, the fixing component 3 further includes a cone 36 fixedly disposed at the bottom end of the insertion rod 33.

[0047] The design of the tip of the cone 36 makes it relatively easier to insert into the socket 31.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
