And exposed injection needle be easy to stab nurse or other people, so general nurse can cover protective cap again, this will increase
The workload of nurse is added.
Summary of the invention
Technical problem to be solved by the present invention lies in: it is easy to be contaminated for the presence of existing injection needle, is easy to stab
Nurse or other people, cover protective cap, improve the problems such as workload, and provide a kind of safety injector that needle point can stretch repeatedly,
To solve the above problems.
Technical problem solved by the invention can be realized using following technical scheme:
A kind of safety injector that needle point can stretch repeatedly, including syringe, needle tubing, needle tubing seat and needle tubing set, the syringe
The core bar for being inside provided with piston and being fixed on the piston, one end of the core bar are extended to outward outside the syringe, institute
The setting of needle tubing seat is stated in the syringe and backwards to the piston, the needle tubing is fixed on the needle tubing seat, the needle tubing set
The front end of the syringe is set and is arranged in parallel with the syringe needle of the needle tubing, which is characterized in that in the needle tubing seat surface to institute
The one end for stating piston is provided with an elastomeric element, and the elastomeric element, which floats, to be arranged on the needle tubing seat, the needle tubing seat
Side is provided with for controlling the flexible switch block of elastomeric element.
In a preferred embodiment of the invention, it is additionally provided in the needle tubing set to limit elastomeric element movement
Limiting device.
In a preferred embodiment of the invention, the limiting device is limited block, and the limited block is fixed on described
On the inner wall of needle tubing set.
In a preferred embodiment of the invention, the elastomeric element is to stretch hose.
In a preferred embodiment of the invention, the switch block includes button and the lock that is arranged on the button
Stop member, one end of the button are connect with the needle tubing seat, the other end pass through the needle tubing set extend outwardly, the lock piece with
The lock piece being arranged on the needle tubing set inner wall is cooperatively connected.
Due to using technical solution as above, the beneficial effects of the present invention are: bullet is used on syringe of the invention
Property component, it is possible to reduce the process of health care workers' Reusability protective cap, avoid nurse by needle point accidentally thorn probability, simultaneously
Alleviate the working strength of nurse.Needle tubing can be released or retract at any time as needed, it is not only simple but also convenient.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is the structural schematic diagram that the safety injector that a kind of needle point of the invention can stretch repeatedly stretches out state.
Fig. 2 is the structural schematic diagram for the safety injector retracted state that a kind of needle point of the invention can stretch repeatedly.
Specific embodiment
In order to be easy to understand the technical means, the creative features, the aims and the efficiencies achieved by the present invention, below into
One step illustrates the present invention.
Referring to Fig. 1 to a kind of safety injector that needle point can stretch repeatedly shown in Fig. 2, including syringe 10, needle tubing 11, needle
Tube socket 12 and needle tubing set 13, housing 10a is cased on syringe 10, piston 10b is provided in syringe 10 and is fixed on piston 10b
On core bar 10c, one end of core bar 10c extends to outward outside syringe 10, and needle tubing seat 12 is arranged in syringe 10 and backwards to piston
10b, needle tubing 11 are fixed on needle tubing seat 12, Nian Jie using adhesive of medical between needle tubing 11 and needle tubing seat 12, and needle tubing set 13 is set
It sets in the front end of syringe 10, and needle tubing set 13 and the syringe needle 11a of needle tubing 11 are arranged in parallel.In needle tubing seat 12 towards piston 10a's
One end is provided with an elastomeric element 20, and elastomeric element 20 preferably stretches hose.Elastomeric element 20, which floats, to be arranged in needle tubing seat 12
On, the side of needle tubing seat 12 is provided with for controlling the flexible switch block 30 of elastomeric element 20.
Switch block 30 include button 31 and lock piece 32, lock piece 32 be arranged on button 31, one end of button 31 with
Needle tubing seat 12 connects, and 31 other end of button passes through needle tubing set 13 and extends outwardly, and lock piece 32 and setting cover on 13 inner walls in needle tubing
