Problems solved by technology

The disadvantages of this method are: 1. The content and concentration of impurities in the water or washing liquid in the drum are not uniform; 2. When the drum rotates, the rubber plugs contact each other and rub against each other, resulting in new insoluble particles; 3. The water or washing after cleaning Although the liquid can be refluxed and filtered, it cannot completely remove impurities from re-contaminating the rubber stopper
Although this me

Example Embodiment

[0035] Example 1

[0036] See Figure 1, Figure 2 and image 3 .

[0037] The device shown in FIG. 1 is adopted, and its composition includes a container 1, a washing tub 2, a water storage bucket 13, a water inlet pipe 12, and a water outlet pipe 6. The container 1 is a cylinder with a diameter of D=800mm, the bottom and side walls of which are arranged with water spray holes 14, the diameter of the water spray holes D 1 =15mm, D 2 =40mm; the hole spacing D of the spray hole 3 =6mm, there are three reflux grooves 15 at the bottom of container 1, and the groove width is H 1 = 8mm. The clean water (deionized water) flowing out of the water storage tank 13 is pressurized by the water inlet pipe 12 and the booster pump 10, and then enters the container 1 and is sprayed from the spray hole 14 with a certain pressure liquid flow. The reflux tank is collected in the drainage tray, and returned to the water storage tank through the outlet pipe 6, the filter device 7, and the water pump 10 ...

Example Embodiment

[0039] Example 2

[0040] The cleaning device and method are the same as in Example 1. Used for cleaning and processing double fork freeze-dried vaccine rubber stopper, each batch processing volume is 30kg. Geometry size of rubber stopper: d 1 =19mm; d 2 =13.5mm; h 1 =9.2mm. The cleaning time is 25 minutes. Table 2 shows the comparison between the test results of insoluble impurity particles on the surface of the obtained product and the rolling cleaning device and method.

Abstract

A method and equipment for washing the medical or medicinal rubber plugs features that the high-pressure liquid stream is used to flush said rubber plugs downward, so the rubber plugs are cleaned in semi-suspended or suspended state. Its equipment is composed of container with multiple water spraying holes on its bottom and side wall, washing drum, water storage, water inlet pipe, water outlet pipe, and the pressurizing pump and pressure regulating valve for spraying the cleaning liquid from water spraying holes.

Description

technical field [0001] The invention relates to a cleaning treatment method and device for medical or medicinal rubber stoppers capable of effectively reducing surface insoluble particles. Background technique [0002] At present, rubber stoppers (hereinafter referred to as rubber stoppers) made of vulcanized rubber (including various vulcanized rubber based on butyl rubber, natural rubber, isoprene rubber, nitrile rubber, etc.) are widely used to seal the opening of medical or pharmaceutical containers. Part, this is because the rubber is elastic and can produce excellent sealing, gas barrier, needle-resistant and other functions for the contents of the container. However, since its production process includes multiple processes such as mixing, molding, vulcanization, punching, trimming, inspection, and packaging, the surface of the rubber plug is easily attached and contaminated with various insoluble impurities during the transfer process of each process. particle. For ...
