Abstract
A controllable in-vivo syringe consists of a needle (1), a case (2), a sleeve (3) and a push rod (4), wherein the outer wall of the push rod (4) clings to the inner wall of the sleeve (3), the needle (1) is fixed on the left end of the sleeve (3), and the most important point is that the needle (1) is fixedly sleeved with the case (2) which is close to the sleeve (3). The utility model can ensure the injection of drugs accurate on the test site so to resolve the defect in the prior art that the routine syringe's insert depth is not easy to control. The utility model is simple in structure, easy to produce, low cost, economical and practical, and has wide usage and wide market application.
Description
One, technical field
This utility model relates to a kind of medical apparatus and instruments, is particularly useful for the controllable type live body syringe of living animal body internal cavity or parenchymal viscera official injection.
Two, background technology
At present, the needle tubing that injectable drug is used, the degree of depth of inserting needle all is to determine with medical worker's oneself experience when injection, the degree of depth of inserting needle is even more important when particularly doing the living animal experiment in medical research.As make medicine or injection cell in the cardiac muscle, under the situation of heartbeat, needle tubing injection with routine, the depth of inserting needle is difficult to grasp, if inserting needle is crossed shallow injectable drug and is gone into visceral pericardium and do not reach experiment purpose, deeply then expose the through chambers of the heart of whole heart if inserting needle is crossed, heart is caused damage, do not reach experiment purpose equally.In injection process, there is very big blindness, easily causes the failure of an experiment.
Three, summary of the invention
This utility model provides a kind of medicine that can guarantee accurately to be expelled to the controllable type live body syringe of experimental point.
Concrete scheme of the present utility model is: a kind of controllable type live body syringe, comprise sleeve, and push rod is in sleeve, and the outer wall of push rod is close to sleeve lining, and the sleeve left end is fixed with syringe needle, and its crux is to be installed with sleeve pipe on the syringe needle.Sleeve pipe is positioned at and leans on into telescopic position, and the sleeve pipe of employing different length can be realized the controllability of injection depth.
Adopt the advantage of such scheme to be: in making living animal body internal cavity or substantive cardiac muscle, during injectable drug, can be expelled to medicine exactly and test the position, but protect Success in Experiment.After one's own heart intramuscular medicine injection or injection cell under the situation of heartbeat, can be expelled to the region of anatomy to medicine exactly, and its reason is exactly to be installed with sleeve pipe on the syringe needle of controllable type live body syringe, has guaranteed the degree of depth of inserting needle when injectable drug.Solved the inaccurate problem of the inserting needle depth in the living animal experiment, made the success of experiment that assurance arranged, use manpower and material resources sparingly, and controllable type live body syringe construction has been simple, be convenient to make, with low cost, economical and practical, to use extensively, market is big.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, specific embodiments
Please see Figure 1, this utility model is a kind of controllable type live body syringe, by sleeve 3, push rod 4 in sleeve 3, the outer wall of push rod 4 is close to sleeve 3 inwalls, sleeve 3 left ends are fixed with syringe needle 1, and its key is: be installed with sleeve pipe 2 on the syringe needle 1, sleeve pipe 2 is positioned at the position near sleeve 3.
Claims (2)
1, a kind of controllable type live body syringe comprises sleeve (3), push rod (4) in sleeve (3), and the outer wall of push rod (4) is close to sleeve (3) inwall, and sleeve (3) left end is fixed with syringe needle (1), it is characterized in that: be installed with sleeve pipe (2) on syringe needle (1).
2, a kind of controllable type live body syringe according to claim 1 is characterized in that described sleeve pipe (2) is positioned at the position near sleeve (3).
