Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of novel injector.
Background technology
Syringe is a kind of common medical instruments, the appearance of syringe be medical instruments field once epoch-making revolution with and syringe needle extracts or this process of injecting gas or liquid is called injection.Syringe is made up of the foraminate syringe of front end band and the piston core bar that matches, be used for a small amount of liquid or its to be injected into region that other method cannot be close or locally extract out from those, when core bar is extracted, liquid or gas suck from syringe front end aperture, liquid or gas are extruded when core bar pushes.Injector syringe can be plastics also can be that glass is made, and usually has the graduation indication representing liquid volume in syringe above.Glass syringe can carry out disinfection with autoclave, but because the processing cost of plastic injector is lower, so modern medical service syringe majority is made of plastic, this also further reduces the risk of blood born diseases.Under prior art condition, syringe in use, when carrying out absorption and action of injection, need two handss to cooperate to carry out simultaneously, for hand-held by under the occasion of other objects at needs one, application is extremely inconvenient, when the piston simultaneously in syringe walks to lower position, some gaps are left between piston and injection tube, easy left drug, causes waste, in medicine, sometimes has some residues in the gap, if residue is expelled in blood with medicinal liquid, personal injury can be caused.
Utility model content
This utility model, in order to overcome deficiency of the prior art, provides a kind of novel injector, and this utility model should use simple and convenient, convenient quick, noresidue during injectable drug, avoids the waste of medicine, and the residue in medicinal liquid can be filtered out, residue is prevented to be strayed in blood.
This utility model is achieved through the following technical solutions:
A kind of novel injector, comprise injection tube, piston, piston rod, described piston is fixedly connected on piston rod, described piston rod is inserted in injection tube, described injection tube one end is provided with syringe needle port, described injection tube one end lateral symmetry is provided with a groove, and described syringe needle port inside is provided with filtering bodies, and filtering bodies can filter out the residue in medicinal liquid; Described injection tube inside is provided with round platform hole, and described piston nose is provided with the round platform head with round platform hole adaptation, when piston arrives to bottom injection tube, and gapless between piston and injection tube, thus reduce drug residue.
As optimal technical scheme of the present utility model, described piston-rod end is provided with finger ring A.
As optimal technical scheme of the present utility model, the finger ring A on described piston rod is oval.
Compared with prior art, the beneficial effects of the utility model are: this utility model should use simple and convenient, and convenient quick, noresidue during injectable drug, avoids the waste of medicine, and the residue in medicinal liquid can be filtered out, prevents residue to be strayed in blood.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, finger ring A; 2, groove; 3, injection tube; 4, piston; 5, round platform head; 6, filtering bodies; 7, syringe needle port; 8, round platform hole; 9, piston rod.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain this utility model, and be not used in restriction this utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
Described a kind of novel injector, comprise injection tube 3, piston 4, piston rod 9, described piston 4 is fixedly connected on piston rod 9, described piston rod 9 is inserted in injection tube 3, described injection tube 3 one end is provided with syringe needle port 7, described injection tube 3 one end lateral symmetry is provided with a pair groove 2, and finger is stretched into described groove 2 by user, injection tube 3 of conveniently holding with a firm grip.Described syringe needle port 7 inside is provided with filtering bodies 6, and filtering bodies 6 can filter out the residue in medicinal liquid; Described injection tube 3 inside is provided with round platform hole 8, and described piston 4 front end is provided with the round platform head 5 with round platform hole 8 adaptation, when piston 4 arrives to bottom injection tube 3, and gapless between piston 4 and injection tube 3, thus reduce drug residue.
As a preferred embodiment of the present utility model, described piston rod 9 end is provided with finger ring A1, and the finger ring A1 on described piston rod 9 is oval.
Compared with prior art, the beneficial effects of the utility model are, this utility model should use simple and convenient, and convenient quick, noresidue during injectable drug, avoids the waste of medicine, and the residue in medicinal liquid can be filtered out, prevents residue to be strayed in blood.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
