Description
Technical field
This utility model relates to medical instruments field, particularly relates to a kind of injector for medical purpose.
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 and inconvenience thereof, when piston simultaneously in syringe walks to lower position, leave some gaps between piston and injection tube, easy left drug, causes waste in the gap.
Utility model content
This utility model, in order to overcome deficiency of the prior art, provides a kind of injector for medical purpose, and this utility model should use simple and convenient, and convenient quick, noresidue during injectable drug, avoids the waste of medicine.
This utility model is achieved through the following technical solutions:
A kind of injector for medical purpose, comprise injection tube, piston, piston rod, described piston is fixing on the piston rod, piston rod is inserted in injection tube, described injection tube one end is provided with syringe needle port, the one end described injection tube being provided with syringe needle port is provided with conical bore in injection tube inside, and the front end of described piston is provided with the nose cone with conical bore adaptation, and the other end of described piston rod is provided with finger ring.
As optimal technical scheme of the present utility model, described finger ring is threaded with adopting between piston rod.
As optimal technical scheme of the present utility model, the opening of described injection tube is provided with the finger holder that a pair positional symmetry is arranged.
As optimal technical scheme of the present utility model, described injection tube is provided with necking section.
Compared with prior art, the beneficial effects of the utility model are: piston rod of the present utility model is provided with finger ring, injection tube is provided with and refers to holder, should use simple and convenient, convenient quick, conical bore on the nose cone of piston nose and injection tube fits tightly and does not stay gap, noresidue during injectable drug, avoids the waste of medicine.
Accompanying drawing explanation
