Abstract
The utility model relates to an improved injector of one time whose structure is improved. A detachable cover is sheathed on the front end of the needle cylinder body, the tail end of the needle cylinder body is a push-and-pull piston rod which is provided with small holes and is a leafy thin rod, so the piston rod is easy to be broken off, the repeatedly use of the utility model can be avoided, and the utility model can be used as a sealed centrifuge tube after the blood (liquid) taking. The utility model overcomes the defects of difficult destruction and insufficient utilization existing in the prior art, and has the advantages of safety, and convenient operation.
Description
A kind of follow-on disposable syringe belongs to area of medical devices.
Instrument as injection and blood drawing (liquid) sample chemical examination is a syringe, in recent years since disposable syringe in preventing cross infection, possess superiority and be widely used in medicine and hygiene fields.But existing disposable syringe has also existed to be solved and has made full use of problem.Mainly be reflected in two aspects.1: use the back quite difficulty it is destroyed and modification by force.Careless slightlyly in the management make the illegal molecule utilization of making profit cause using repeatedly and lack medicinal knowledge people misuse, moved by the ignorant child and make toy and play and want.The existing report of these situations.2: that blood is expelled in the centrifuge tube reuse stopper lid is tight in order to extract behind the blood promptly for conventional blood drawing assay step, send the laboratory to wait for centrifugal extracting work, careless slightly especially epidemic victim's the blood of environmental pollution that promptly causes brings suitable inconvenience simultaneously disposable syringe not to be fully used yet to behaviour person.
The purpose of this utility model is: provide a kind of the work to be easy to destroy after syringe uses, make the disposable syringe of providing convenience behind blood drawing (liquid) sample.
This utility model be achieved in that the needle cylindrical unit opening direction of syringe with opposite originally be that the needle cylindrical unit front end is that big muzzle has a dismountable upper shield, needle cylindrical unit tail end piston place is the push-pull bar that the aperture piston rod then adopts lobate thin excellent type, and fractureing after easy to use like this reaches demolition purpose.
Advantage of the present utility model: one: human body is prevented epidemic or after medicine controls as syringe, the operator easily destroys promptly piston push-pull rod fractureed to it and it is blocked use leak repeatedly.Two: behind human body blood drawing (liquid) sample, the operator fractures push-pull bar and just forms the centrifuge tube of a Totally-enclosed-type automatically, reduces operation sequence and avoids causing environmental pollution, disposable syringe is reached make full use of.
Detailed structure of the present utility model and embodiment accompanying drawing are described:
Among the figure: 1: be syringe needle, 2: be to isolate rubber, 3: be the syringe lid, 4: be piston, 5: for behind blood drawing (liquid) sample as the centrifuge tube place that fractures, 6: be needle cylindrical unit, 7: be push-pull bar, 8: do the place that fractures behind the syringe.
Embodiment: follow-on disposable syringe, using method is identical with original syringe.Follow-on push-pull bar that do not exist together destruction that is easy to fracture is blocked and is used leak to provide convenience for blood drawing (liquid) sample repeatedly.
Claims (1)
1, a kind of follow-on disposable syringe, it comprises: syringe needle, isolate rubber, the syringe lid, piston, needle cylindrical unit, push-pull bar, combine, it is characterized in that: the needle cylindrical unit front end is with a dismountable syringe and covers at lid the isolation rubber is housed, and push-pull bar fractures when having two places of fractureing to be respectively injection, fractures during blood drawing (liquid) sample, the needle cylindrical unit tail end is provided with the scrobicular ring purpose for ease of injection, does not imitate again simultaneously to hinder needle cylindrical unit to make centrifuge tube.
