Abstract
The utility model relates to a pre-charge type injector, which belongs to the field of a medical injector. The utility model comprises a needle seat which is arranged on the front end of the injector. The main technical point is that the needle seat is provided with a rigid bowl-shaped protecting sleeve, the protecting sleeve is provided with an elastic sealing plug with a sealing groove, and the sealing groove is sleeved on the needle seat. After the utility model is improved, the needle seat is added with a sealing device, and thereby the needle is separated from the needle tube. When in use, the needle is just sleeved on the needle seat after the needle is opened, and thereby the utility model has the advantages of small size and convenient use, which can guarantee the safety and normal use of the injector.
Description
Technical field
This utility model belongs to the injector for medical purpose field, specifically is a kind of medical precharging type syringe.
Background technology
Syringe is one of utensil of each medical institutions' indispensability, for the ease of first aid, the medical apparatus and instruments designer has developed precharging type syringe, promptly just the direct fill of injectable drug in glass syringe, and injection needle is installed on the glass syringe, syringe and medicinal liquid packing container are united two into one, direct injection during use, very easy to use and shelf-life is the same with cillin bottle with the peace bottle.It has following very outstanding advantage:
1. do not have cross infection when using, unclean air does not reach medicine in the ward, accomplishes positive safety injection;
2. the doctors and nurses is extremely easy to use, need not to take out medicine, need not to install syringe needle, direct injection, disposable use;
More 3. can make full use of the noresidue medicinal liquid as high-grade medicines such as insulin, blood products;
4. open-air occasion is fit to the self first aid injection;
But in the use of reality, medical personnel find the precharging type syringe of prior art, because needle tubing and syringe needle are integral structure, cause the volume of syringe integral body bigger, carry inconvenience, and syringe needle subject to damage, influence the normal use of syringe,, just need improve for this reason prior art, reducing the syringe volume, and can ensure safe, the normal use of syringe.
The utility model content
The purpose of this utility model is to solve above-mentioned the deficiencies in the prior art, and prior art is improved, and provides a kind of volume little, easy to use, and can ensure the precharging type syringe of safe, the normal use of syringe.
For achieving the above object, this utility model is achieved through the following technical solutions:
Be a kind of precharging type syringe, comprise the needle holder of syringe front end, the present technique main points are to be provided with on the needle holder the bowl-shape sheath of rigidity, and the elastic packing plug that has sealed groove is put in the embedded installing of sheath, and sealed groove is sleeved on the needle holder.
For the bonded firmness of reinforced sheath and sealing-plug contact site, avoid the pollution of medicinal liquid, sheath and sealing-plug contact site be processed with respectively mutual coupling revolve the silk and spin slot.
In addition, for further strengthening sealing, the isolation to medicinal liquid, setting-in high resiliency sealing shroud in the sealed groove.
Therefore this utility model owing to installed sealing device additional on the needle holder, can make syringe needle separate with needle tubing after above-mentioned improvement, and it is little, easy to use to have a volume, and can ensure the advantage of safe, the normal use of syringe.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described in further detail:
Fig. 1: this utility model example structure sketch map.
The specific embodiment
As shown in Figure 1, this precharging type syringe comprises the needle holder 6 of syringe front end, and the present technique main points are to be provided with on the needle holder 6 the bowl-shape sheath 5 of rigidity, and the elastic packing plug 1 that has sealed groove 3 is put in sheath 5 embedded installings, and sealed groove 3 is sleeved on the needle holder 6.
For reinforced sheath 5 and the bonded firmness in sealing-plug 1 contact site, avoid the pollution of medicinal liquid, what sheath 5 and sealing-plug 1 contact site were processed with mutual coupling respectively revolves silk and spin slot 4.
In addition, for further strengthening sealing, the isolation to medicinal liquid, setting-in high resiliency sealing shroud 2 in the sealed groove.
The utility model owing to installed sealing device additional on the needle holder, can make syringe needle separate with needle tubing after above-mentioned improvement, uses In time, only needs cover after the syringe needle unpacking installed on the needle holder and get final product, so it is little, easy to use to have a volume, and can ensure syringe The advantage of safe, normal use.
