Abstract
The utility model discloses a pollution-prevention syringe, which consists of a needle tube, a plunger and a plunger fixed cap. The top end of the plunger is a thick column with the diameter which is fit with the inner diameter of the needle tube, the middle and lower part thereof is a thin column with the diameter which is smaller than the inner diameter of the needle tube, and the other end of the plunger is provided with a handle which is fixed by a thread; the plunger fixed cap is connected with the needle tube by the thread, the middle of which is provided with a round hole which is fit with the thin column of the plunger, and a gas hole is arranged at the side of the round hole. When in using process of the syringe, the plunger part which is drawn out is not contacted with the inner wall of the needle tube, which can effectively prevent the pollution of the inner wall of the needle tube and the medicine liquid, so as to prevent the damage on the patients.
Description
Technical field:
This utility model relates to a kind of hygiene medical treatment apparatus, specifically a kind of syringe.
Background technology:
In the existing technology, the plunger integral body of syringe all is cylindrical, and it is exposed outside in use to pull out part, and the nurse touches easily in operating process and pollutes, and plunger pollutes the syringe inwall again after advancing, and the syringe inwall contacts with medicinal liquid and pollutes medicinal liquid.The easier liquid medicine contamination that causes when nurse's centralized configuration medicine particularly, thus harm caused to patient.
Summary of the invention:
The purpose of this utility model is to provide a kind of anti-pollution injector.
The purpose of this utility model is to realize by following technical scheme: it is made up of needle tubing, plunger, plunger locking cap, it is characterized in that: the top of plunger is diameter and the needle tubing internal diameter thick cylinder that adapts, the middle and lower part is the thin cylinder of diameter less than the needle tubing internal diameter, and the other end of plunger has by the fixed handle of screw thread; The plunger locking cap is connected with needle tubing by screw thread, in the middle of it circular hole that adapts with the thin cylinder of plunger is arranged, and there is pore on the circular hole limit.
On the described plunger locking cap is external screw thread, is female thread on the needle tubing.
Can be female thread also on the described plunger locking cap, be external screw thread on the needle tubing.
Advantage of the present utility model is: the middle and lower part of plunger is the thin cylinder of diameter less than the needle tubing internal diameter, and in use, the part that is drawn out does not contact with needle interior wall, has prevented pollution needle interior wall and medicinal liquid effectively, thereby prevents the harm to patient.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the front view of this utility model plunger locking cap.
Fig. 3 is the side view of this utility model plunger locking cap.
The specific embodiment:
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
Shown in Figure 3 as Fig. 1 Fig. 2, anti-pollution injector is made up of needle tubing 3, plunger, plunger locking cap 4, the top of plunger is diameter and the needle tubing internal diameter thick cylinder 1 that adapts, and the middle and lower part is the thin cylinder 2 of diameter less than the needle tubing internal diameter, and the other end of plunger has by the fixed handle 5 of screw thread; Plunger locking cap 4 is connected with needle tubing 3 by screw thread, is external screw thread on the plunger locking cap, is female thread on the needle tubing, in the middle of the plunger locking cap 4 circular hole 6 that adapts with the thin cylinder of plunger is arranged, and there is pore 7 on the circular hole limit.
