Description
Technical field
This utility model relates to a kind of entry needle, especially a kind of Novel injection pin.
Background technology
For there is cross infection when avoiding to the mankind or animal input or take out medium, the necessary single use of hypodermic syringe, after a procedure namely as garbage disposal.The maximum disposable syringe of current use is made up of cavity cylindrical shell, syringe needle and the push rod with piston be assemblied in cylindrical shell.Its weak point is: meeting residual liquor in the union joint on syringe, so not only can cause waste, also can bring dangerous and inconvenient factor, if dealt with improperly in processing procedure, to the severe contamination to environment be caused, also may become the source of pestilence.
Puncture needle is dropped immediately upon completion of the injection, as medical refuse burning process.Because injection needle contacts with patient body fluid, and exist most advanced and sophisticated, before destroying, easily operator are stabbed, cause cross infection, therefore there is very large potential safety hazard.
In addition, existing puncture needle generally only has an injection orifice, when the dose injecting medicinal liquid is very large, cannot shorten the time required for injection operation.
Summary of the invention
For the weak point existed in the problems referred to above, this utility model provides a kind of waste avoiding medicinal liquid, avoids operator being stabbed before destruction puncture needle, and can improve injecting medical liquid injection efficiency, shortens the Novel injection pin of injection required time.
For achieving the above object, this utility model provides a kind of Novel injection pin, comprise syringe part (1) and puncture needle (2), described syringe part (1) comprises cylindrical shell (12) and push rod (11), the end of described cylindrical shell (12) is provided with the union joint (13) connecting described puncture needle (2), the end of described push rod (11) is provided with piston head (111), described piston head (111) is evenly provided with three road fins, described push rod (11) is mobilizable to be arranged in described cylindrical shell (12), described piston head (111) center is provided with projection (112),
Needle body (20) in described puncture needle (2) is hollow form structure, the front end of described needle body (20) forms needle tip (21), the opening part of described needle tip (21) forms the first injection orifice (22), the end of described needle body (20) is connected with needle stand (4), the outside wall surface of described needle body (20) is enclosed with a slip sheath (3), is formed with anti-slip veins (5) in the outside wall surface of described slip sheath (3);
The outside wall surface of described needle body (20) also offers one second injection orifice (23), and described second injection orifice (23) is arranged near on the position of described needle tip (21).
Above-mentioned Novel injection pin, wherein, described projection (112) length is less than described union joint (13), and the external diameter of described projection (112) is less than the internal diameter of described union joint (13).
Above-mentioned Novel injection pin, wherein, the cross section of described slip sheath (3) is oval ring structure.
Above-mentioned Novel injection pin, wherein, described needle stand (4) is arranged on the outer wall of described union joint (13).
Compared with prior art, this utility model has the following advantages:
By arranging the projection matched with union joint on the top of piston, avoid the waste of medicinal liquid, improve the safety of disposable syringe post-processed;
By slip sheath is slided to needle tip position, avoid needle tip to be exposed to the external world, thus avoid before destruction, operator being stabbed;
By at the second injection orifice offered on needle tip position, the flow that medicinal liquid is injected in vivo can be improved, thus improve the efficiency of injection, shorten the required time of injection.
Accompanying drawing explanation
Fig. 1 is exploded view of the present utility model.
Main Reference Numerals is described as follows:
1-syringe part; 11-push rod; 111-piston head; 112-projection; 12-cylindrical shell; 13-union joint; 2-puncture needle; 20-needle body; 21-needle tip; 22-first injection orifice; 23-second injection orifice; 3-slip sheath; 4-needle stand; 5-anti-slip veins
Detailed description of the invention
As shown in Figure 1, this utility model comprises syringe part 1 and puncture needle 2, syringe part 1 comprises cylindrical shell 12 and push rod 11, the end of cylindrical shell 12 is provided with the union joint 13 of connecting puncture needle 2, the end of push rod 11 is provided with piston head 111, piston head 111 is evenly provided with three road fins, push rod 11 is mobilizable to be arranged in cylindrical shell 12, and piston head 111 center is provided with projection 112.Wherein, projection 112 length is less than union joint 13, and the external diameter of projection 112 is less than the internal diameter of union joint 13.
Needle body 20 in puncture needle 2 is hollow form structure, and the front end of needle body 20 forms needle tip 21, and the end of needle body 20 is connected with needle stand 4.Needle stand 4 is arranged on the outer wall of union joint 13, thus is arranged on syringe part 1 by puncture needle.
Form the first injection orifice 22 at the opening part of needle tip 21, on the position of needle tip 21, also offer the second injection orifice 23 close.
The outside wall surface of needle body 20 is enclosed with a slip sheath 3, and the cross section of this slip sheath 3 is oval ring structure.In addition, anti-slip veins 5 is formed with in the outside wall surface of slip sheath 3.
By the projection matched with union joint arranged in piston tip, avoid the waste of medicinal liquid, improve the safety of disposable syringe post-processed, the three road fins of this utility model also by arranging on piston, solve the problem of piston seal performance difference, thus enhance the sealing of piston, be conducive to the propelling movement of medicinal liquid.
In addition, slip sheath, after finishing using, is slided to needle tip position by entry needle, avoids needle tip to be exposed to the external world, thus avoids operator being stabbed before destruction.Slip sheath cross section is oval ring, can well be attached on puncture needle, can not initiatively movement; With the two ends that hands extruding slip sheath is looser, its position of can easily sliding.
