Abstract
The utility model discloses a disposable syringe with a filter, which is composed of a needle cylinder, a needle pin and a needle head. The utility model is characterized in that a filer with a needle head seat is arranged on a nipple at the front end of the needle cylinder, the front end of the syringe is provided with a nipple, the size of the nipple corresponds to the size of the needle head seat of the needle head and the needle head is arranged on the nipple at the front end of the filter through the needle head seat. The utility model has the advantages of simple structure and novel design. Because the filter with a needle head seat is arranged on the nipple at the front end of the needle cylinder, insoluble particles or bottle stopper crumbs in liquid medicine can be filtered under the condition of being pumped in the needle cylinder. In order to prevent that the insoluble particles or the bottle stopper crumbs remain inside the needle head, the needle head can be changed again when the utility model is used for patients' intramuscular injection. Thus, the utility model can thoroughly avoid the condition that the insoluble particles or the bottle stopper crumbs inject into patients' bodies to cause clinical complications.
Description
Technical field this utility model belongs to the injector for medical purpose technical field, is specifically related to a kind of syringe of disposable band filter.
Background technology is present, and the syringe of clinical use is made of syringe, pintle and syringe needle, and syringe needle is installed on the nipple of syringe front end by needle holder.The syringe of prior art, is extracted into insoluble granule in the medicinal liquid or bottle stopper bits in the syringe when the preparation injection easily owing to there is not defecator, when giving patient's intramuscular injection, is expelled in patient's body, causes clinical complication.
Summary of the invention the purpose of this invention is to provide a kind of syringe of disposable band filter, to overcome the deficiencies in the prior art.
For achieving the above object, the syringe of the disposable band filter of this utility model, constitute by syringe, pintle and syringe needle, its main points are filters that the nipple of syringe front end is provided with the band needle holder, the front end of said filter is provided with nipple, the size of nipple is corresponding with the needle holder of syringe needle, and syringe needle is installed on the nipple of filter front end by needle holder.
This utility model is simple in structure, novel in design, owing to be provided with the filter of band needle holder on the nipple of syringe front end, insoluble granule in the medicinal liquid or bottle stopper can obtain filtering when considering to be worth doing in being extracted into syringe.In order to prevent residual insoluble granule or bottle stopper bits in the syringe needle, when giving patient's intramuscular injection, can change syringe needle again, like this, can thoroughly avoid insoluble granule or bottle stopper bits to be expelled in patient's body, cause clinical complication.
Appended drawings is this utility model structural representation.
The specific embodiment with reference to the accompanying drawings, this utility model is made of syringe 2, pintle 1 and syringe needle 7, the nipple 3 of syringe 2 front ends is provided with the filter 5 of band needle holder 4, the front end of filter 5 is provided with nipple 6, the size of nipple is corresponding with the needle holder of syringe needle, and syringe needle is installed on the nipple of filter front end by needle holder.
