Abstract
The utility model provides a syringe carrying with medicine used for injection, which is composed of a plastic ampoule, a fixed adhesive tape, a needle tube, a sealing cap, a sealing snap ring, a double-layer rubber plug, an air bag washer and a thin film for closing mouth. The sealing snap ring which is clamped with the sealing cap is sheathed at the back end of the outside of the needle tube. The neck of the plastic ampoule is extended to the terminal port of the thin cylindrical tube and is connected with the needle seat of the injection needle. The air bag washer is sheathed on the front end of the needle tube. The thin film for closing mouth is sealed on the opening at the front end of the needle tube and is coiled on the surface of the needle seat of the injection needle. The air bag washer, the thin film for closing mouth, the needle tube and the injection needle are connected to a whole by the fixed adhesive tape to form a syringe. The utility model has the advantage of easy use, is particularly suitable for using in egress diagnosing-treating and the field.
Description
This utility model is to belong to a kind of syringe.
Syringe commonly used at present, it is very cumbersome in use will to finish injection process, opening medicine peace bottle aluminium lid is earlier also sterilized, opening injection solvent peace bottle is again sterilized, take syringe and extract injection solvent, inject in the medicine peace bottle,, be drawn in the needle tubing start injection again after treating to dissolve fully with the hands vibration.Its process complexity, operator's labor intensity height not only, and go wrong easily, when first aid, make troubles especially.
The purpose of this utility model is to make a kind of prefilled syringe, makes medicine and solvent be stored in one respectively, and is easy to use, simple to operate, can eliminate cumbersome operating process in traditional injection process, prevents unexpected pollution.
This utility model is mainly by plastics peace bottle 1, entry needle 2, fixedly adhesive tape 3, needle tubing 4, sealing cap 5, seal snap ring 6, double-deck plug 7, air bag packing ring 8 and sealing film 9 are formed.This utility model has solved to separate between former medicine and the solvent and has stored and converged two difficult problems of dissolving.Solid drugs such as powder place the leading section in the needle tubing 4, available double-deck plug 7 sealed storage.The outer-rear end of needle tubing 4 is with seal snap ring 6, can with sealing cap 5 clampings that are enclosed within needle tubing 4 rear ends, in its sealing cap 5 openings burr is arranged, be stuck in the groove of seal snap ring 6, needle tubing 4, seal snap ring 6 and sealing cap 5 are combined into one.Drug blockage in needle tubing 4, is prevented to pollute, save the original packaging material such as the glass ampoule of medicine, make things convenient for medicine to dissolve fast again.The drug solvent sealing places in the plastics peace bottle 1, guarantees solvent ne-leakage and pollution.Eck at plastics peace bottle 1 is a layer plastic sheeting, and the draw point that is beneficial to entry needle thrusts conveniently.The thin round long tube of band elastic thread is extended at plastics peace bottle neck place again, and its length slightly is longer than the draw point of entry needle.In the end of elastic thread mini diameter tube burr is arranged, can tightly be enclosed within on the needle stand of entry needle, plastics peace bottle 1 is joined together with entry needle, prevent that the draw point of entry needle from being polluted.Be with annular air bag packing ring 8 at the front opening place of needle tubing 4, and opening sealed, prevent that medicine from spilling and pollute with sealing film 9.Needle tubing 4 front opening ends insert in the entry needle needle stand, make sealing film 9 turnups to entry needle needle stand outside, reuse fixedly adhesive tape 3 is linked together entry needle 2, sealing film 9, air bag packing ring 8 and needle tubing 4, and plastics peace bottle 1, entry needle 2 are joined together with needle tubing 4, forms prefilled syringe.
During use, as long as firmly needle tubing 4 front ends are pushed away to last, at this moment air bag packing ring 8 squeezes brokenly, and the sealing film that will be enclosed in front opening punctures, and makes needle tubing 4 front ends just insert the draw point joint of entry needle 2, at this moment be placed on the interior draw point of elastic thread mini diameter tube that plastics peace bottle 1 eck extends, pass the plastic sheeting of its eck, insert in the solvent in the plastics peace bottle 1, solvent is along the draw point of entry needle, after entering the dissolving of needle tubing 4 front ends and medicament mixed, i.e. injectable.
This utility model compared with prior art, it is simple in structure, medicine and solvent are enclosed in the one, prevent accidental pollution, avoid adorning wrong medicine, favourable emergency call salving in busy.This syringe is simplified complicated operations process in the past, alleviates operator's labor intensity.Easy to carry, be suitable for going out using under diagnosis and treatment and the field condition.Owing to save the drug packages material, reduce cost, alleviate patient economy burden.

Embodiment of the present utility model:
This utility model mainly contains plastics peace bottle 1, entry needle 2, fixedly adhesive tape 3, needle tubing 4, sealing cap 5, seal snap ring 6, double-deck plug 7, air bag packing ring 8 and sealing film 9 are formed.Wherein entry needle 2, needle tubing 4, double-deck plug 7 and fixedly adhesive tape 3 for selecting part for use.The medical plastic of the transparent or semitransparent shape of other plastics peace bottle 1 usefulness is injection molded into cylindrical bottle, and its eck place is a plastic sheeting, and extends into the thin cylindrical tube of elastic thread, and its pipe end internal orifice has burr.Air bag packing ring 8 usefulness non-toxic plastics are injection molded into the annular membrane aeration ring, and sealing film 9 is the brittle plastic thin film.Sealing cap 5, seal snap ring 6 are used injection molding.
Double-deck plug 7 is packed in the needle tubing 4, and seal snap ring 6 is sleeved on the outer-rear end of needle tubing 4, sealing cap 5 is enclosed within the rear end of needle tubing 4 again, and is connected on the seal snap ring 6.After medicine is injected by needle tubing 4 front openings under aseptic condition, air bag packing ring 8 is enclosed within needle tubing 4 front opening places, seal with sealing film 9 then, the draw point of entry needle 2 inserts in the eck elasticity of extension screw thread mini diameter tube of plastics peace bottle 1, and the burr in the eck elasticity of extension screw thread mini diameter tube front end is connected on the needle stand of entry needle 2.The needle stand of entry needle is enclosed within on needle tubing 4 front openings, and sealing film 9 turnups join needle tubing 4, air bag packing ring 8, sealing film 9, entry needle 2 together with fixing adhesive tape 3 on needle stand, form prefilled syringe.
