Abstract

The utility model discloses a novel syringe of medical treatment, including syringe casing, push rod, piston ring, disposable bellows anther sac, anther sac discharge nozzle, syringe needle screwed pipe, syringe needle seat, interior needle tubing and injection needle tubing, compare with prior art, the utility model discloses a disposable anther sac direct use, syringe itself does not have any medicine contact, can use repeatedly, need not to adopt extra bottled, and it is also convenient to use, and direct use has stopped the chance with the air contact, reduces the infection rate, has the value of popularization and application.

Description

A kind of medical treatment novel injector

Technical field

The utility model relates to a kind of medical instrument more particularly to a kind of medical novel injectors.

Background technique

Syringe is a kind of common medical instruments.Early in the 15th century, Italian's Ka Di Nellie just proposes syringe Principle.Gas or liquid are mainly extracted or injected with syringe needle.In the prior art, it in order to avoid infection, uses disposable Needle and syringe head, syringe inject when, need to knock out the bottleneck of glass drug, then draw medical fluid and injected, first, strike Bottle is easy to crack and hurt hand, in addition, be abandoned after entire syringe first use, also more waste of resource, in addition, drawing drug Process, drug contacts with air, also will receive the pollution in air to a certain extent, accordingly, there exist rooms for improvement.

Utility model content

The purpose of this utility model is that solve the above-mentioned problems and provides a kind of medical novel injector.

The utility model achieves the above object through the following technical schemes:

The utility model includes injector housing, push rod, piston ring, disposable bellows anther sac, anther sac ejection nozzle, syringe needle Screwed pipe, needle holder, inner needle tube and injection needle, the push rod are connect with the piston ring, and the piston ring is located at the note It in emitter shell, and can slide, the disposable bellows anther sac is located in the injector housing, the piston ring and institute The tail portion contact of disposable bellows anther sac is stated, the anther sac ejection nozzle of the disposable bellows anther sac exposes the injection Outside the front end of device shell, the syringe needle screwed pipe is fixedly connected with one end of the needle holder, the syringe needle screwed pipe with it is described Anther sac ejection nozzle is threadedly coupled, and the inner needle tube is fixed in the needle holder, and is located in the syringe needle screwed pipe, and described Inner needle tube can puncture the anther sac ejection nozzle, and the injection needle is fixed on the other end of the needle holder, and the interior needle It is connected between pipe and the injection needle.

The utility model has the beneficial effects that:

The utility model is a kind of medical novel injector, and compared with prior art, the utility model is using disposable Anther sac directly uses, syringe itself without any medicament contact, can Reusability, without additional bottled, use also side Just, it directly uses, has prevented the chance contacted with air, reduce infection rate, have the value of popularization and application.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

In figure: the disposable bellows anther sac of 1- injector housing, 2- push rod, 3- piston ring, 4-, 5- anther sac ejection nozzle, 6- Syringe needle screwed pipe, 7- needle holder, 8- inner needle tube, 9- injection needle.

Specific embodiment

The utility model is described in further detail with reference to the accompanying drawing:

As shown in Figure 1: the utility model include injector housing 1, push rod 2, piston ring 3, disposable bellows anther sac 4, Anther sac ejection nozzle 5, syringe needle screwed pipe 6, needle holder 7, inner needle tube 8 and injection needle 9, the push rod are connect with the piston ring, The piston ring is located in the injector housing, and can slide, and the disposable bellows anther sac is located at the syringe In shell, the piston ring is contacted with the tail portion of the disposable bellows anther sac, the disposable bellows anther sac it is described Anther sac ejection nozzle exposes outside the front end of the injector housing, and one end of the syringe needle screwed pipe and the needle holder is fixed to be connected It connects, the syringe needle screwed pipe is threadedly coupled with the anther sac ejection nozzle, and the inner needle tube is fixed in the needle holder, and is located at In the syringe needle screwed pipe, and the inner needle tube can puncture the anther sac ejection nozzle, and the injection needle is fixed on the needle The other end of headstock, and be connected between the inner needle tube and the injection needle.

The working principle of the utility model is as follows:

Disposably bellows anther sac 4 is disposable, extracts push rod 2 and piston ring 3, places disposable bellows anther sac 4, in injector housing 1, are threadedly coupled by syringe needle screwed pipe 6 with anther sac ejection nozzle 5, at this point, inner needle tube 8 punctures anther sac row Mouth 5 out, push rod 2 and piston ring 3 are put back in injector housing 1, can be injected by injection needle 9, the compression of piston ring 3 one Secondary property bellows anther sac 4, medical fluid can be discharged, and when replacement, abandon disposable bellows anther sac 4 and needle portion.

The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
