Abstract
The invention provides a medical injector. The injector comprises a push rod, a needle and an injector body; a first-level filter membrane is arranged at the lower end of the injector body; a second-level filter membrane is arranged between the needle and the first-level filter membrane; the injector body is provided with scales. The injector can effectively filter bottle stopper scraps and impurities; as two levels of filtration are adopted, tiny impurities can be well filtered out; the medical injector is simple in structure, economic and practical; the injector is provided with the scales, and the volume of injection solution can be well measured.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be specifically related to a kind of syringe for medical treatment.
Background technology
Syringe conventional in the market, when extracting the medicine in ampoule bottle for the tiny glass disintegrating slag in ampoule bottle, is difficult to prevent entering of glass chip completely; When piercing air-tight bottle, being difficult to prevent entering of rubber stopper impurity completely, having the possibility polluted; Injecting drug use can produce a large amount of particulate matter besides, and insoluble granule can produce the consequence more much bigger than the side effect of medicine itself after entering the health of people, and the treatment safety of precipitation on patient of medicine itself also can produce certain impact in addition.Present people have recognized the seriousness of this problem, start to adopt the syringe needle with defecator or needle tubing, but yet there is certain deficiency in this syringe needle or needle tubing, wherein most important be exactly filtering material selection on: the too sparse filter effect that easily causes is bad, and too Mi Zeyi causes filtering material to block, so that liquid medicine is not smooth.Also there is now a kind of two syringe filtered, be just equipped with two syringe needles, with one when making up a prescription, separately change one during injection, although such configuration ensure that filter effect, use inconvenience, be difficult to when workload is large ensure timely replacing, do not reach due effect.
Summary of the invention
The object of the invention is to overcome weak point that prior art exists and provide a kind of syringe for medical treatment.
For achieving the above object, the technical scheme taked: a kind of syringe for medical treatment, described syringe comprises push rod, syringe needle and syringe body, single filter film is provided with in the lower end of described syringe body, between described syringe needle and described single filter film, be provided with cascade filtration film, described syringe body is provided with graduation mark.
As the preferred embodiment of the present invention, the aperture of described cascade filtration film is greater than the aperture of single filter film.
As the preferred embodiment of the present invention, the range of described graduation mark is 0 ~ 50ml.
Beneficial effect of the present invention is: the invention provides a kind of syringe for medical treatment, and this syringe effectively can filter bottle stopper bits and impurity, owing to have employed cascade filtration, well can also filter out fine impurity, and its structure is simple, economical and practical; And this syringe has graduation mark, the volume of injection solution can be measured well.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the syringe for medical treatment of the present invention; In figure, 1 is push rod, and 2 is syringe needle, and 3 is single filter film, and 4 is cascade filtration film, and 5 is syringe body, and 6 is graduation mark.
Detailed description of the invention
For better the object, technical solutions and advantages of the present invention being described, below in conjunction with specific embodiment, the invention will be further described.
Embodiment 1
A kind of embodiment of the syringe for medical treatment of the present invention, described syringe comprises push rod 1, syringe needle 2 and syringe body 5, single filter film 3 is provided with in the lower end of described syringe body 5, cascade filtration film 4 is provided with between described syringe needle 2 and described single filter film 3, described syringe body 5 is provided with graduation mark 6, the aperture of described cascade filtration film 4 is greater than the aperture of single filter film 3, and the range of described graduation mark 6 is 0 ~ 50ml.
Finally to should be noted that; above embodiment is only in order to illustrate technical scheme of the present invention but not limiting the scope of the invention; although be explained in detail the present invention with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to technical scheme of the present invention or equivalent replacement, and not depart from essence and the scope of technical solution of the present invention.
Claims (3)
