Abstract
The utility model belongs to the field of medical equipment, a puncture injector is equipped with the needle tubing, the syringe needle, the frenulum, and the frenulum adopts elastic silica gel, and its one end is equipped with annular lasso, overlaps at the syringe needle afterbody, and the other end is equipped with bellied ball, is equipped with the jack on the needle tubing lateral wall, and bellied ball gets into and locks in the jack. The structure is simple and reasonable, namely the structure is improved on the prior injector, the manufacture is easy, the cost is low, the use is convenient, and the unnecessary trouble and the workload increase caused by the falling of the needle head are effectively avoided.
Description
Affiliated technical field
This utility model belongs to medical instruments field, specifically a kind of puncture injection device.
Background technology
The syringe that uses generally is a disposable syringe at present, and its syringe needle and needle tubing connection place connect as one both by planar frictional force.Dosing clinically, adopt disposable syringe when doing thoracic cavity or abdominal paracentesis, taking out under the situation that dose is many or the liquid bottles internal pressure is big, in liquid bottles during dosing, owing to be connected not tight between needle tubing and the syringe needle, be easy to cause needle tubing and syringe needle to disconnect, medicinal liquid overflows outside bottle, causes losing and wasting of medicinal liquid; When doing thoracic cavity or abdominal paracentesis, need to extract thoracic cavity or hydroabdomen with disposable needle tubing, its repeatable operation easily makes needle tubing and syringe needle be connected not tight, even finger fixes, also causes needle tubing and syringe needle to disconnect easily, even causes syringe needle to come off.So not only pollute, easily cause antibacterial or viral infection, and need once more puncture again when changing needle tubing, not only increased patient's misery but also caused unnecessary waste, also increased workload to medical personnel.
Summary of the invention
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple and reasonable for structure, and cost is low, makes easily, and is easy to use, can effectively reinforce the puncture injection device that is connected of needle tubing and syringe needle.
This utility model solves the scheme that its technical problem takes: a kind of puncture injection device, be provided with needle tubing, syringe needle, it is characterized in that being provided with frenulum, frenulum adopts elastic silica gel, and the one end is provided with annular collar, be enclosed within the syringe needle afterbody, the other end is provided with the ball of projection, and the needle tubing sidewall is provided with jack, and the ball of projection enters locking in the jack.
This utility model is simple and reasonable for structure, promptly improves on original syringe, makes easily, and cost is low, and is easy to use, avoids syringe needle to come off effectively and unnecessary trouble and the workload brought strengthen.
Description of drawings
This utility model is described in detail by embodiment below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Labelling among the figure: 1, syringe needle, 2, lasso, 3, frenulum, 4, the ball of projection, 5, jack, 6, needle tubing.
The specific embodiment
Shown in Figure 1, a kind of puncture injection device has needle tubing 6, syringe needle 1, it is provided with frenulum 3, and frenulum 3 adopts elastic silica gel to make, and an end is provided with annular collar 2, can be enclosed within syringe needle 1 afterbody, the other end is provided with the ball 4 of projection, and the needle tubing sidewall is provided with jack 5, and the ball 4 of projection enters locking in the jack 5.Annular collar 2 with frenulum 3 one ends during use is enclosed within the syringe needle afterbody, and the ball 4 of other end projection is inserted in connection and fixing in the jack 5, and needle tubing and syringe needle can not disconnected.When using the action need needle tubing to separate,, again needle tubing is separated with syringe needle as long as the ball 4 of projection is separated in jack 5 with syringe needle.This utility model is simple and reasonable for structure, promptly improves on original needle tubing, makes easily, and cost is low, and is easy to use, avoids syringe needle and needle tubing to come off effectively and the unnecessary trouble brought and loaded down with trivial details workload.
