Abstract
The utility model provides a needle protective cap of dynamic vulcanization type thermoplastic elastomer TPV (Thermo-Plastic Vulcanizate) for a pre-embedded injector. The needle protective cap of the dynamic vulcanization type thermoplastic elastomer TPV for the pre-embedded injector comprises a needle protective cap main body made of the dynamic vulcanization type thermoplastic elastomer TPV; a needle hole is formed in the needle protective cap main body; and a bottom edge bulge is arranged at the lower part of the needle protective cap main body. The TPV needle protective cap uses the dynamic vulcanization type thermoplastic elastomer TPV, so that the material has the characteristics of high own purity and less extractive and transportable matters; the TPV needle protective cap has the advantages of good elasticity, moderate intensity, easiness of molding, various sterilization-resistant requirements, environmental friendliness, recycling utilization the like; and the production uses primary molding in an injection molding process, so that one-step positioning, fewer process steps, and clean and environment-friendly products can be realized.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of syringe needle helmet.
Background technology
Medical pre-encapsulated injector is had concurrently medical packaging and injects the high-quality injector assembly of two kinds of functions by what the advanced technologies device fabrication went out by the Medicine packaging material exactly, is a kind of advanced person's medical packaging form; It has packing and storing medicine and two kinds of effects of medicine injection simultaneously, is mainly used in the higher biologics of added value, genomic medicine and immune drug packaging, and the packing of domestic treatment chronic disease medicine; Pre-encapsulated injector is a very important accessory with the hard helmet of syringe needle, and the application percentage of the syringe needle helmet of pre-encapsulated injector constantly increases at present, does not occur a comparatively suitable auxiliary products on market, well large-scale production.
The conventional syringe needle helmet that uses is to adopt butadiene-styrene rubber (SBR) or halogenated butyl rubber and synthetic polyisoprenes rubber production, usually need to add the compounding ingredients such as various filleies and vulcanization accelerator, need through batching, refining glue, sulfuration, a plurality of steps such as die-cut, the contaminated probability of product to be increased.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of pre-encapsulated injector dynamic vulcanization analog thermoplastic elastomer TPV syringe needle helmet of cleaner health.
In order to address the above problem by the following technical solutions: a kind of pre-encapsulated injector dynamic vulcanization analog thermoplastic elastomer TPV syringe needle helmet, comprise by the syringe needle helmet main body that adopts dynamic vulcanization analog thermoplastic elastomer TPV to be made, syringe needle helmet main body is provided with the syringe needle hole, and the bottom of syringe needle helmet main body is provided with the root edge projection.
Syringe needle hole opening part is positioned at syringe needle helmet main body bottom center place; The root edge projection is step-like.
Described syringe needle hole be shaped as the shape that cylinder and cone combine.
This utility model adopts dynamic vulcanization analog thermoplastic elastomer TPV, and the purity of material own is high, and extractable and transportable thing are few; Have the advantages such as good springiness, moderate strength, easily molding, anti-various sterilization requirements, environmental protection section recycling; Produce and adopt the injection molding technique one-shot forming, settle at one go, processing step is few, the clean environmental protection of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of pre-encapsulated injector comprises by the syringe needle helmet main body 1 that adopts dynamic vulcanization analog thermoplastic elastomer TPV to be made with dynamic vulcanization analog thermoplastic elastomer TPV syringe needle helmet; Syringe needle helmet main body 1 is provided with syringe needle hole 2, syringe needle hole 2 be shaped as the shape that cylinder and cone combine, syringe needle hole opening part is positioned at syringe needle helmet main body bottom center place; The bottom of syringe needle helmet main body 1 is provided with root edge projection 3, and the root edge projection is step-like.
Produce pre-encapsulated injector syringe needle helmet with dynamic vulcanization analog thermoplastic elastomer TPV, can process on conventional thermoplastic injection former, adopt the injection molding technique one-shot forming.
