Description

Medicine-storaged disposable syringe

Technical field:

This utility model relates to a kind of disposable syringe, a kind of specifically medicine-storaged disposable syringe.

Background technology:

The disposable syringe of use is gone up in medical treatment at present and the medicine and the storage capsule (ampoule, bottle) thereof of injection respectively is an independently integral body, and existing division is as follows:

1. disposable syringe (hereinafter to be referred as syringe): form by syringe needle, syringe, nook closing member three parts.

(1) syringe needle: form by the syringe needle tube of stainless steel and the syringe needle tail pipe of plastics matter.The rear end of syringe needle tube firmly is fixed in the syringe needle tail pipe prosopyle, and front end is Horse hoof face inclined-plane.During use, the syringe needle tail pipe is nested with on the syringe needle joint of syringe front end.(2) syringe: cylindric.Outer wall is marked with not isometric scale, and front end has an outstanding forward thin tube-like syringe needle joint, is about 1cm, in order to syringe needle to be installed.(3) nook closing member: form by nook closing member dish and needle core handle.A, nook closing member dish: be positioned at the needle core handle front end, round pie is manufactured by the elastic material of tool.There is a round pie button inner chamber that is opened on the bottom in the centre in this disk body, and needle core handle can insert intracavity in the button by accent in the button.B, needle core handle: be divided into button, handle neck, handle body, final quotaion four parts.1) button: be positioned at the needle core handle front end, for being slightly less than the round pie of button inner chamber, it is contained in intracavity in the button at ordinary times, and needle core handle and nook closing member dish are together interconnection by this chamber.2) handle neck: between button and handle body 3) cross section of handle body is "+" font.4) final quotaion: be the disk shape, be fixed on handle body end.

2. medicine and storage capsule: the medicine of injection has three kinds of solution, powder and lyophilized preparation, and they are enclosed in the nature of glass ampoule of bullet shape by appearance or bottle cap is in the bottle of rubber mass.

The problem that exists has: 1. the syringe of current use itself does not possess any prompting or prevents reusable structure or sign, so that can be repeatedly used, pathogenic microorganism such as hepatitis virus, HIV (human immunodeficiency virus) (Human Immunodeficiency Virus) can be propagated by them and give the patient, cause the popular of disease and spread, especially the phenomenon that is repeated to use in the rural area is more serious.National health administrative department repeatedly reaffirms to forbid to reuse, but polyisomenism is still general.2. because syringe and medicine and container thereof are two independently integral body, bring inconvenience for whole treatment operating process, very numerous and diverse.Each operating process all needs through opening the injector package bag, take out syringe, syringe needle is installed, polishing, sterilization is also broken or is destroyed the ampoule head into two with one's hands, medicinal liquid is pumped in the syringe, makes puncture injection behind the skin degerming, these steps are time-consuming bothersome again, and are to needs the race against time acute myocardial infarction of rescuing, the critically ill patient of respiratoring palpitating suddenly stopping, more apparent and unable to do what one wishes especially.3. the aforesaid operations process is all carried out there being bacterium to have in the air-polluting environment.After the peace bottle was opened, medicine was polluted unavoidably, and medicinal liquid can cause potentiality harm to the patient after injecting human body.4. brute force is knocked peace bottle open or when breaking into two with one's hands, easily causes glass fragment to splash or scratches finger, contaminated environment, injury human body.5. the operator who has ignores the incompatibility of medicine, and the suction of several medicinal liquids is blended in the syringe, and human body is worked the mischief or malpractice takes place.6. the syringe of using do intramuscular injection, commonly used is 5 milliliters, 2 milliliters and 10 milliliters three kinds, especially with 5 milliliters the most using more.Amount of liquid medicine in the suction syringe often only occupies the syringe total length Remainder has no value for use, just goes out of use after the disposable use, and be a very big waste to raw material, also cause environmental pollution, increase patient's financial burden.

The utility model content

The purpose of this utility model provides a kind of medicine-storaged disposable syringe, to solve the problem that in the existing syringe medicine is not housed and makes generation drug contamination in the operating process.

This utility model comprises medicine administered by injection integral injector, syringe needle and needle core handle, and the medicine administered by injection integral injector comprises syringe, is positioned at the syringe needle joint of syringe end; Syringe needle comprises syringe needle tail pipe and syringe needle tube; Needle core handle comprises nook closing member dish, button, handle neck handle body and final quotaion, is provided with the button inner chamber in the nook closing member dish, has accent in the button in the nook closing member tray bottom; Described nook closing member dish is located at the syringe intracavity bottom, and the nook closing member dish is apart from syringe tail mouth 2-3 millimeter; In the syringe inner chamber, medicine is housed; The prosopyle of syringe needle joint is sealed with the prosopyle diaphragm seal, and syringe tail mouth is sealed with tail mouth diaphragm seal; Described syringe needle tube is made up of syringe needle tube leading portion and syringe needle tube back segment, and the prosopyle diaphragm seal that the syringe needle tube back segment passes the syringe needle joint enters syringe needle junction block intracavity.

This utility model no longer is stored in the medicine of injection in peace bottle or the bottle at ordinary times, and foot directly is stored in the syringe, abolishes the ampoule and the bottle that store medicine.The medicine of injection is stored in the syringe at ordinary times.Advantage of the present utility model has and has 1. reached a people one pin one medicine, has fundamentally stopped the reusable disadvantage of syringe, has cut off the pathophoresis approach, has avoided cross infection, has safeguarded that the patient's is healthy.2. wholistic therapy operating process is injected human body with medicine in the free of contamination operating process of absolutesterility, avoided the pollution of medicine.3. obviously reduced operation link, needle core handle and syringe needle have been installed from opening the package to,, only needed 3-4 operation link, for treating and rescuing and shortened the time to skin degerming.Avoided the past when brute force is knocked peace bottle open or broken into two with one's hands, caused glass fragment to splash or scratch finger, the phenomenon of injury human body.4. stop operation lack of standardization, avoided the operator that the past has that several medicinal liquids suctions are blended in the syringe, human body is worked the mischief or the phenomenon of malpractice takes place.5. shortened syringe and needle core handle length, discarded peace bottle and bottle, made needle core handle become public product, these series of measures have reduced the making raw material, have reduced waste, have saved fund, have alleviated patient's financial burden.

The utility model is described in further detail below in conjunction with accompanying drawing.
