Abstract
The utility model discloses a simple disposable anti-pollution sterile injection syringe, which is used for solving the problem of reduction in the dosing speed existing in a conventional anti-pollution sterile injection syringe. The simple disposable anti-pollution sterile injection syringe comprises a needle cylinder and a piston rod, wherein a telescopic cylinder is arranged in the inner cavity of the needle cylinder; the telescopic cylinder is formed by connecting a telescopic rod and a bottom ring; the bottom ring is fixedly arranged on the bottom of the needle cylinder; an insertion hole is formed in the center of the bottom ring; the piston rod is inserted into the telescopic rod through the insertion hole; and the head of the telescopic rod is fixedly arranged on the bottom surface of a piston head. Due to the adoption of the simple disposable anti-pollution sterile injection syringe, a piston of the injection syringe is prevented from polluting the needle cylinder, hospital infection is reduced, the dosing speed is increased, an operator can use the sterile injection syringe flexibly, and a needle tube is prevented from being polluted.
Description
Technical field
This utility model belongs to disposable medical article, specifically the disposable anti-pollution asepsis injector of a kind of plain type.
Background technology
Though existing anti-pollution asepsis injector plays a significantly greater role to preventing nosocomial infection, dosing speed has in use obviously slowed down.
The utility model content
The purpose of this utility model provides the disposable anti-pollution asepsis injector of a kind of plain type, to solve the problem of the dosing speed that slowed down that existing anti-pollution asepsis injector exists.
Technical solutions of the utility model are as follows: the disposable anti-pollution asepsis injector of a kind of plain type, comprise syringe and piston rod, the inner chamber of described syringe is provided with retracting cylinder, described retracting cylinder is formed by connecting by expansion link and foundation ring, described foundation ring is fixed on the syringe bottom, the center of described foundation ring is provided with socket, and described piston rod inserts in the described expansion link by described socket, and the head of described expansion link is fixed on the described piston head bottom surface.
This utility model has avoided syringe piston to pollute syringe in the dosing process, has reduced nosocomial infection, has also accelerated dosing speed.The operator can be applied in a flexible way, namely avoided the pollution needle tubing.

Fig. 1 is the structural representation of the disposable anti-pollution asepsis injector of a kind of plain type;
Fig. 2 is the structural representation of retracting cylinder foundation ring in the disposable anti-pollution asepsis injector of a kind of plain type;
Fig. 3 is the state diagram after the disposable anti-pollution asepsis injector of a kind of plain type is taken out medicine.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
As depicted in figs. 1 and 2, the disposable anti-pollution asepsis injector of a kind of plain type, comprise syringe and piston rod, the inner chamber of syringe 4 is provided with retracting cylinder, retracting cylinder is formed by connecting by expansion link 2 and foundation ring 7, and foundation ring 7 is fixed on the syringe bottom 5, and the center of foundation ring 7 is provided with socket 6, piston rod 3 inserts in the expansion link 2 by socket 6, and the head of expansion link 2 is fixed on the piston head bottom surface 1.The interior shape of socket 6 is four jiaos of stars, and is suitable with the shape of piston rod 3.The piston rod that piston rod in the present embodiment is used than present syringe on the market is thin by 1/5th.Retracting cylinder can be made of plastics.
Fig. 3 shows the state diagram after the disposable anti-pollution asepsis injector of plain type is taken out medicine, during use, and pulling piston rod 3, expansion link 2 compresses automatically, extracts medicine.Promote piston 3, expansion link 2 slowly restores, and has cut off the approach of piston rod pollution syringe.
