Description
Technical field
The utility model belongs to the field of medical instrument technology, and in particular to a kind of with the disposable of safety protective cover
Asepsis injector.
Background technique
Currently, Dispoable medical syringe is storage and transport under aseptic conditions, usually injector for medical purpose is put
Enter in a closed polybag, since the syringe needle of syringe can puncture polybag in polybag and destroys gnotobasis,
Using after being over also due to syringe needle stretch out puncture medical waste recycling polybag, therefore, at present on syringe needle
One protective case is set, polybag will not be punctured again when syringe needle is put into protective case, shielded to polybag.But
It is to be easily lost after current protective case is removed, pillow is exposed after such syringe abandons is easy to accidentally injure other people outside, non-
Normal danger.
Utility model content
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of one with safety protective cover
Secondary property uses asepsis injector, and structure is simple, and rationally, safe and practical, protective case is not allowed easy to be lost for design.
To solve the above problems, technical solution used by the utility model is as follows:
A kind of disposable sterilized syringe with safety protective cover, including needle tubing, syringe needle, push rod and piston, institute
It states push rod and piston is all set in the needle tubing, and one end of push rod is connected with the piston, the other end of the push rod is set
There is connecting hole, the one end of the needle tubing is equipped with the first connector, and one end of first connector is connected with the second connector, the needle
Head is connected on second connector；The sleeve for coating the syringe needle is connected on first connector, described sleeve one end
Diameter is consistent with the internal diameter of the connecting hole.
Further, the diameter of first connector is greater than the diameter of second connector, first connector and described
The fluid bore being connected with the needle tubing is equipped on second connector.
Further, the connecting hole inner wall is equipped with internal screw thread, and the outer surface of described sleeve one end is equipped with external screw thread,
The external screw thread and the internal screw thread are in mating connection.
Further, the surface of the needle tubing is equipped with a pair of of supporting device, and the supporting device includes baffle and setting
Annulus in the baffle side, the baffle and annulus are all set on the needle tubing.
Further, the baffle and the annulus are an integral molding structure.
Further, the side of the annulus is equipped with arc panel, and one end of the arc panel is set on the needle tubing.
Compared with prior art, the utility model has the beneficial effects that: firstly, sleeve is covered plays protection on the first connector
The effect of syringe needle, secondly, push rod can be played the role of in this way in use, remove sleeve and connect on push rod, it is convenient
Medical worker carries out injection work, is removing sleeve after the completion of injection and is reinstalling on the first connector, closes syringe needle to come again,
Other people would not be stabbed after throwing away in this way, greatly reduces risk, structure is simple, and design is rationally, safe and practical.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is structural schematic diagram when the utility model is used；
In attached drawing, 1 is needle tubing, and 2 be syringe needle, and 3 be push rod, and 4 be piston, and 5 be connecting hole, and 7 be the first connector, and 8 be second
Connector, 9 be sleeve, and 10 be fluid bore, and 11 be baffle, and 12 be annulus, and 13 be arc panel.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Such as Fig. 1 and Fig. 2, a kind of disposable sterilized syringe with safety protective cover, including needle tubing 1, syringe needle 2,
Push rod 3 and piston 4, the push rod 3 and piston 4 are all set in the needle tubing 1, and one end of push rod 3 and 4 phase of piston
Even, the other end of the push rod 3 is equipped with connecting hole 5, and the one end of the needle tubing 1 is equipped with the first connector 7, first connector 7
One end be connected with the second connector 8, the second connector is to be threadedly coupled with the second connector for connecting sleeve, sleeve, disassembly in this way
Convenient, the syringe needle 2 is connected on second connector 8；The sleeve for coating the syringe needle 2 is connected on first connector 7
9, the diameter of described 9 one end of sleeve is consistent with the internal diameter of the connecting hole 5, and 5 inner wall of connecting hole is equipped with internal screw thread, described
The outer surface of 9 one end of sleeve is equipped with external screw thread, and the external screw thread and the internal screw thread are in mating connection, preferably, sleeve
The diameter of one end is greater than other end diameter, for example, end diameter of the sleeve connection on the first connector is greater than sleeve far from first
The end diameter of connector, and the diameter of the end is less than or equal to the internal diameter of needle tubing, and sleeve is far from the first fitting end
It can connect in connecting hole, push rod can be lengthened in this way, it is easy to use.
For the ease of connection sleeve and syringe needle, the diameter of first connector 7 is greater than the diameter of second connector 8, institute
It states and is equipped with the fluid bore 10 being connected with the needle tubing 1 on the first connector 7 and second connector 8.
For the ease of hand syringes, the surface of the needle tubing 1 is equipped with a pair of of supporting device, and the supporting device includes
