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 method can avoid the mutual contact and friction of the rubber plugs and the repeated pollution of the cleaning solution, its disadvantages are: 1. The rubber plugs are immersed in the cleaning solution under static conditions, and the overall cleaning effect is not ideal; 2. In the middle and edge of the hanging basket The cleaning effect between the two areas is inconsistent, especially the rubber stopper in the middle area cannot be effectively cleaned

Embodiment 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 . Container 1 is a cylinder with a diameter of D=800mm, and its bottom and side walls are arranged with water spray holes 14, and the aperture of the water spray holes is D 1 = 15mm, D 2 =40mm; the hole spacing D of the spray hole 3 =6mm, three reflow grooves 15 are arranged at the bottom of the container 1, the groove width H 1 = 8mm. The clean water (deionized water) flowing out from the water storage tank 13 enters the container 1 after being pressurized by the water inlet pipe 12 and the booster pump 10 and is sprayed out from the water spray hole 14 with a liquid flow with a certain pressure. The reflux tank is collected in the drainage tray, and returns to the water storage tank through the water outlet pipe 6, the filter device 7, and t...

Embodiment 2

[0040] The cleaning device and method are the same as in Example 1. It is used for washing and processing double-fork freeze-dried vaccine rubber stoppers, and the processing volume of each batch is 30kg. Geometric size of rubber stopper: d 1 =19mm; d 2 = 13.5 mm; h 1 = 9.2 mm. Cleaning time is 25 minutes. Table 2 compares the test results of insoluble impurity particles on the surface of the obtained product with those of 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 ...
