Precision medicine liquid light-avoiding filter and manufacturing method thereof

Abstract

The invention relates to a precision medicine liquid light-avoiding filter and a manufacturing method of the precision medicine liquid light-avoiding filter. The precision medicine liquid light-avoiding filter comprises an upper cover of the filter, a filtering film and a lower cover of the filter. The upper cover of the filter and the lower cover of the filter can be mutually buckled and welded. The upper cover of the filter is formed by molding double layers in an injection mode. The inner layer of the upper cover is a colorless transparent layer. The outer layer of the upper cover is a light-avoiding layer added with a light-avoiding agent. A liquid entering end is arranged on the upper cover of the filter. At least one air outlet is formed in the upper cover of the filter. A lyophobic film is fixed at the air outlet. The lower cover of the filter is formed by molding double layers in an injection mode. The inner layer of the lower cover is a colorless transparent layer. The outer layer of the lower cover is a light-avoiding layer added with a light-avoiding agent. A liquid outlet end is arranged on the lower cover of the filter. The filtering film is arranged between the upper cover of the filter and the lower cover of the filter. A medicine liquid cavity is formed between the filtering film and the upper cover of the filter. A filtering cavity is formed between the filtering film and the lower cover of the filter. The precision medicine liquid light-avoiding filter and the manufacturing method of the precision medicine liquid light-avoiding filter are obvious in use effect. A product is simple and reasonable in structure, good in light-avoiding effect, safe, reliable and meanwhile, simple in manufacturing technology.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a precision medicinal liquid light-shielding filter and a manufacturing method thereof. Background technique [0002] At present, in order to meet the requirements of light-shielding for clinically used light-shielding filters, the main measures are as follows: (1) Use light-shielding sleeves to cover the liquid medicine filter that does not have light-shielding performance to achieve the light-shielding effect. The problem is that the specifications and structural forms of infusion sets produced by various manufacturers are different, which leads to the difficulty of processing the light shielding sleeve and the compatibility of use; (2) Some use light shielding agents added to the raw materials, and some even use added Ordinary dyes are used to achieve the purpose of light protection. Therefore, during the infusion process, the light protection agent will inevitably...
