Abstract
A needle head hard protective cap for a pre-potting injector is formed by embedding a rubber soft protective cap into a hard plastic protective cap. The needle head hard protective cap for the pre-potting injector has the advantages of being simple in structure, lower in cost and convenient to produce on a large scale. By assembling the rubber soft protective cap and the hard plastic protective cap in a full-automatic vacuum tamponade assembly machine in clean environment, the needle head hard protective cap for the pre-potting injector ensures that a composite isoprene rubber IR307 soft needle cap can be correctly matched with a medical polypropylene hard plastic protective cap, and therefore man-made pollution is reduced, and quality of the needle head hard protective cap for the pre-potting injector is further guaranteed.
Description
Technical field
This utility model belongs to technical field of medical instruments, relates in particular to a kind of pre-encapsulated injector with the hard helmet of syringe needle.
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 the market, well large-scale production.
The utility model content
Technical problem to be solved in the utility model provides a kind of pre-encapsulated injector with the hard helmet of syringe needle.
Provide following technical scheme in order to address the above problem: a kind of pre-encapsulated injector is with the hard helmet of syringe needle, by forming in the soft helmet embedding of the rubber duroplasts helmet.
The soft helmet of described rubber matches with the cavity of duroplasts helmet.
The soft helmet of described rubber is pyramidal structure, is provided with the syringe needle hole in the middle of the soft helmet of rubber; The thin-wall construction with cavity of duroplasts helmet for matching with the soft helmet of rubber.
The cavity internal diameter of the external diameter of the soft helmet of rubber and duroplasts helmet matches, and its lower edge of the soft helmet of rubber is provided with projection, and the endoporus inwall place of corresponding duroplasts helmet is provided with groove, and groove matches with projection.
The soft helmet of described rubber is the soft helmet of rubber of being made by synthetic polyisoprenes rubber IR307; Described duroplasts helmet is the duroplasts helmet that polypropylene for medical article is made.
The soft helmet of rubber and duroplasts helmet fit together by fully automatic vacuum tamponade kludge.
This utility model is simple in structure, and cost is lower, is convenient to produce in enormous quantities.Employing is in clean environment, the soft helmet of rubber and duroplasts helmet are assembled in a fully automatic vacuum tamponade kludge, guaranteed the correct collocation of the soft pin medicated cap of synthetic isoprene rubber IR307 and polypropylene for medical article duroplasts helmet, reduced artificial pollution, guaranteed that further pre-encapsulated injector is with the quality of the hard pin medicated cap of syringe needle.
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 is with the hard helmet of syringe needle, embedded in the duroplasts helmets 1 by the soft helmet 2 of rubber to form, and the soft helmet 2 of rubber and duroplasts helmet 1 fit together by fully automatic vacuum tamponade kludge.The soft helmet 2 of rubber is pyramidal structure, is provided with syringe needle hole 4 in the middle of the soft helmet 2 of rubber; The thin-wall construction with cavity of duroplasts helmet 1 for matching with the soft helmet 2 of rubber.The external diameter of the soft helmet 2 of rubber and the cavity internal diameter of duroplasts helmet 1 match, and its lower edge of the soft helmet 2 of rubber is provided with projection 5, and the endoporus inwall place of corresponding duroplasts helmet 1 is provided with groove 3, and groove 3 matches with projection 5.
Preparation technology: the soft helmet of rubber is the very clean gel-free anion synthetic polyisoprenes rubber IR307 that adopts, adopt very clean peroxide vulcanizing system, add inertia and the good ultra-high molecular weight polyethylene of dispersibility in the prescription, improve lubricity and the chemical inertness of sizing material, and very property and the hardness of elastomeric compound; Directly adopt injection moulding vulcanization technique to carry out molding, the product size precision is high, and the product density is good.
Duroplasts helmet employing polypropylene for medical article in conjunction with accurate hot runner mould, is produced the polypropylene duroplasts helmet with cavity and thin-wall construction on the precision injection molding machine.
To synthesize the soft helmet of isoprene rubber IR307 rubber and polypropylene for medical article duroplasts protects in a fully automatic vacuum tamponade kludge and assembles production.
