Abstract
The utility model provides an anti-contamination injector, comprising a syringe barrel and a plunger. The outer end of the plunger is provided with a push handle; an extensible seal barrel is arranged outside the plunger, the outer end of the seal barrel is connected hermetically with the push handle, and the inner end of the seal barrel is connected hermetically with the upper opening of the syringe barrel; the push handle in the seal barrel is provided with ventilation holes which is provided with a seal rubble plug inside. This utility model has the advantages of simple structure, convenient operation and avoiding contamination caused by hand touching the plunger, which is applied for muscle injection or liquid medicine preparation.
Description
Technical field
This utility model relates to a kind of medical supplies, refers in particular to a kind of flexible shell type anti-pollution injector that is used for intramuscular injection or medicinal liquid allotment.
Background technology
At present, the syringe that generally uses in the hospital is made up of urceolus and piston rod, and medical personnel are by the push-and-pull piston rod in operation, realizes operations such as aspiration medicinal liquid, admixing medical solutions, injection.But find that in use medical personnel are when carrying out operation such as aspiration medicinal liquid, admixing medical solutions, injection, finger can touch piston rod, causes liquid medicine injection to pollute easily.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to use, can prevent to point a kind of flexible shell type anti-pollution injector that the contact piston bar pollutes.
The purpose of this utility model is achieved in that a kind of flexible shell type anti-pollution injector, comprise syringe and piston rod, be provided with handle in the piston rod outer end, wherein: described piston rod periphery is provided with telescopic Sealed casing pipe, the outer end and the handle of Sealed casing pipe are tightly connected, and the inner upper oral part with syringe of Sealed casing pipe is tightly connected; Be provided with passage on the handle in Sealed casing pipe, passage is provided with the sealing plug.
Telescopic Sealed casing pipe described in above-mentioned a kind of anti-pollution injector is an organ type.
After this utility model adopts said structure,, can prevent from effectively that medical personnel from point directly to touch piston rod when operating syringe, avoid causing pollution, the assurance injection safety liquid medicine injection by telescopic Sealed casing pipe is set outside piston rod.
Description of drawings
Below in conjunction with the embodiment in the appended drawings this utility model is described in further detail, but does not constitute any restriction of the present utility model.
Fig. 1 is the structural representation of a kind of specific embodiment of this utility model;
Fig. 2 is a user mode sketch map of the present utility model.
Among the figure: 1-syringe, 2-piston rod, 3-handle, 4-Sealed casing pipe, 5-passage, 6-seal plug.
The specific embodiment
As shown in Figure 1, a kind of anti-pollution injector of the present utility model comprises syringe 1 and piston rod 2, be provided with handle 3 in piston rod 2 outer ends, be provided with telescopic Sealed casing pipe 4 in piston rod 2 peripheries, telescopic Sealed casing pipe 4 adopts organ type in the present embodiment, also can adopt diaphragm type; The outer end of Sealed casing pipe 4 and handle 3 are tightly connected, and Sealed casing pipe 4 inner upper oral parts with syringe 1 are tightly connected, and can form confined space like this, prevent that syringe from using the direct contact piston bar of finger; Be provided with passage 5 on the handle 3 in Sealed casing pipe 4, passage 5 is provided with sealing plug 6, and the effect of passage 5 and sealing plug 6 is to be used for sterilization, adjust blood pressure and assembling in process of production; When this utility model specifically uses, consult shown in Figure 2ly, identical with the common syringe using method, medical personnel can grip handle 3 with hands, can carry out suction, mixing or the injection operation of medicinal liquid; Because of the sealing function of telescopic Sealed casing pipe 4, can avoid liquid medicine contamination effectively.
