After the completion of taking, then changes fine needle and injected.It is cumbersome in this way, and it is possible in operating process, staff's hand
The pollution that fine needle causes syringe needle can be touched, is also easy to that staff's hand is caused to stab when replacing syringe needle.
Utility model content
In view of the above technical problems, the utility model provides integral type double needle injection device, and the device is without more
Under the premise of needle exchange head, liquid can be conveniently extracted, after extracting liquid, passes through rotating needle, so that it may to carry out
Injection.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：
Integral type double needle injection device, including needle component and the syringe with plunger part, the needle component packet
Include flexible syringe needle and injection needle, the injection needle is located in flexible syringe needle, the flexible syringe needle and injection needle respectively with
Syringe is connected to, and the flexible syringe needle is equipped with catch with syringe connectivity part, and the company of flexible syringe needle and syringe can be controlled by catch
Logical state, the catch is hinged with syringe, and the catch is equipped with elastic component with syringe hinged place, and the flexible syringe needle is by least two
Casing socket composition is saved, and forms stretching structure, is threaded between casing.
The elastic component is reed, and protective layer is provided with outside the reed.
The protective layer is medical grade rubber layer.
The syringe uses transparent material, convenient for liquid inside observation syringe.
The material of described sleeve pipe is metal.
The utility model compared with prior art, has an advantageous effect in that：
Flexible syringe needle is made of the casing being socketed one by one, is often threaded between section casing；When needing to extract liquid,
Casing can be extended by rotating, carry out the extraction of liquid after elongation by casing；After extraction, by reversely rotating casing
It retracts, is injected by injection needle, when injection, catch hinders the connection of casing and syringe, and liquid is avoided to be flowed out from casing.
The quick extraction and injection of liquid may be implemented while easy to use in the utility model.

Specific implementation mode
The technical scheme in the utility model embodiment is clearly and completely described below, it is clear that described reality
It is only the utility model a part of the embodiment to apply example, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this reality
With novel protected range.
As shown in Fig. 1~2, integral type double needle injection device, including needle component and the syringe 2 with plunger part 1,
Needle component includes flexible syringe needle and injection needle 3.Syringe 2, which is one end, has top, the cylindrical structure of another end opening to pass through column
Plunger member 1 can be drawn fluid into syringe 2.Flexible syringe needle and injection needle 3 are arranged at 2 top of syringe.
Injection needle 3 is located in flexible syringe needle, and flexible syringe needle and injection needle 3 are connected to syringe 2 respectively, and the syringe needle that stretches is logical
It crosses through-hole 8 to be connected to syringe 2, catch 4 is equipped at through-hole 8, can block or leak out through-hole 8 by catch 4, to which control is flexible
The connected state of syringe needle and syringe 2, catch 4 is hinged with syringe 2, and catch 4 is equipped with elastic component with 2 hinged place of syringe.Elastic component is
Reed 9, reed 9 are wrapped with medical grade rubber layer.It is, of course, also possible to using torque spring or helical spring as elastic component
It uses.The both ends of reed 9 couple with catch 4 and syringe 2 respectively.
Flexible syringe needle is socketed by least two section casings and is formed one by one, is formed flexible pipe structure, is joined by screw thread between casing
It connects.Often the internal diameter of section casing is more than the outer diameter of injection needle 3, and the cross-sectional area of each casing is sequentially increased from inside to outside.
As shown in Fig. 2, flexible syringe needle is made of three section casings, the internal diameter of casing 37 is more than the outer diameter of casing 26, casing
26 internal diameter is more than the outer diameter of casing 1.
The other end of one 5 one end of casing and 2 top attachment of syringe, casing 1 is joined by one end of screw thread and casing 26
It connects, the other end of casing 26 is coupled by screw thread with one end of casing 37.When needing elongation, casing 1 can be pinched with hand
Or syringe 2, elongation is realized by revoling tube 37 and casing 26.When needing to shrink, casing 1 or syringe are pinched with hand
2, by reversely rotating casing 26 and casing 37, make in one 5 retraction casing 26 of casing, in 26 retraction casing 37 of casing.When
So, the quantity of casing can be adjusted according to actual conditions.
As shown in figs. 34, the effect of catch 4 is the connection or disconnection of control flexible syringe needle and syringe 2, when extraction liquid
When, liquid jacks up catch 4（Elastic deformation occurs for reed 9, generates elastic potential energy）, through-hole 8 is exposed, liquid is made to can smoothly enter into
In syringe 2；When injecting fluid, in reed 9（Discharge elastic potential energy）Under the action of, so that catch 4 is blocked through-hole 8, avoids liquid
It is flowed out from casing by through-hole 8.
Catch 4 is arranged inside 2 top of syringe, can only inwardly open；It can be jacked up when extracting liquid, meeting when injecting fluid
It is compressed by liquid.
In use, syringe 2 is pinched with hand, by rotating outermost casing（Casing 37）And intermediate casing（Casing 26）,
Casing is extended（Total length after casing elongation is more than the length of injection needle 3）, then extracted.After drug extracts, use
Hand pinches syringe 2, by reversely rotating outermost casing（Casing 37）And intermediate casing（Casing 26）, casing is retracted successively
（Total length after cannula retraction is less than the length of injection needle 3）, so that injection needle 3 is exposed, may then pass through injection needle 3
It is injected.
Only the preferred embodiment of the utility model is explained in detail above, but the utility model be not limited to it is above-mentioned
