Integrated double-color needle protective cap

Abstract

The invention belongs to the technical field of medical instruments, and particularly relates to an integrated double-color needle protective cap. The integrated double-color needle protective cap comprises an inner protective cap and an outer protective cap, wherein the inner protective cap is made of a thermoplastic elastomer; the inner protective cap is sleeved with the outer protective cap, and the outer protective cap and the inner protective cap are of an integrated structure; and an inner cavity channel is formed in the inner protective cap. The inner protective cap and the outer protective cap are integrally formed in the clean room through injection molding, the service life is longer, the cost is lower, the process is completed in the clean room, and the protective cap can be put into use without cleaning; the thermoplastic elastomer (TPE) is adopted as the inner protective cap of the integrated double-color needle protective cap, and the inner protective cap does not have the phenomena of yellowing, white frost and the like, so the integrated double-color needle protective cap is safer and safer to use; and the simple and three-dimensional structural design is adopted, so that the practicability is higher, and the use is more convenient.

Description

technical field [0001] The invention belongs to the field of medicine packaging, and in particular relates to an integrated two-color needle protective cap. Background technique [0002] Currently commonly used needle shields are assembled from PP / PE shields and rubber shields. The rubber shields currently produced on the market have many and complex procedures, low pass rate, high equipment investment, large floor space, and high production costs. , waste of resources, and also cause great environmental pollution. [0003] The current production process of the needle shield has the following disadvantages: first, the assembled needle shield is prone to separation between the PP / PE shield and the rubber shield during use, which brings inconvenience to the operator; second, the rubber needle The inner hole of the protective cap is small, and it is difficult for the cleaning liquid to enter the inner cavity of the needle protective cap, resulting in the inner cavity of the ru...
