Description
Technical field
The present invention relates to technical field of medical instruments, and in particular to a kind of syringe.
Background technology
The syringe that domestic hospitals use at present is made up of syringe needle and needle tubing, and intermediate connections are detachable, by it during use
It is seated.But slotting tension is commonly encountered in clinical position and causes taking, pressure mistake when inserting not tight and causing to push away medicine
Big easy to fall off, medicine is splashed, and conflict between doctors and patients are caused when serious.
On the other hand, there is researcher to improve the structure of syringe, but the syringe construction after improvement becomes more
Complexity, departing from the conventional structure of syringe, it is unfavorable for mass producing, and operates and be not also inconvenient, especially
For the practice medical personnel just to have entered a profession, practicality is not strong.
In addition, when syringe punctures to patient in use, piercing depth is often by virtue of experience controlled,
To mitigate the pain brought to patient as much as possible, especially some privileged sites are punctured, depth is pierced into and seems outstanding
For key, but it is again undoubtedly a problem for the practice medical personnel to lack experience.
The content of the invention
In order to solve the problems, such as that prior art is present, it is an object of the invention to provide a kind of syringe, its syringe needle dismounting side
Just it is and difficult for drop-off and simple in construction, it is easy to use, it is practical.
The technical scheme that the present invention solves above-mentioned technical problem is as follows：
A kind of syringe, including：Syringe needle, syringe and the push rod being arranged in syringe；Wherein, syringe needle include needle tubing and

Body, sleeve pipe are set in the outside of connecting tube and the space for accommodating connector are formed between sleeve pipe and connecting tube, sleeve pipe
Inwall is provided with screw thread, and the pitch of screw thread and the thickness of annular protrusion match so that connector is connected with casing threads, connecting tube
It is connected with sleeve pipe with cylinder, push rod is provided with cylinder.
The present invention sets sleeve pipe on the outside of the connecting tube of existing syringe, by the screw thread of internal surface of sleeve pipe, recycles syringe needle
Itself there is annular protrusion, realize the threaded connection between syringe needle and sleeve pipe, so as to which syringe needle is conveniently mounted on syringe.This
On the one hand the sleeve pipe of invention causes the junction of syringe needle and syringe to have enough compression resistances, syringe needle will not when can ensure to push away medicine
Come off；On the other hand due to the presence of sleeve pipe, the pollution to syringe needle and syringe junction can be prevented, while be also prevented from
Liquid splash when syringe needle comes off under fortuitous event, avoids drug waste；Another further aspect, the presence of sleeve pipe do not change original injection
The structure of device, can be general with the syringe needle of existing Clinical practice syringe needle and transfusion device front end, is easy to clinical application, and in life
Mould structure is adjusted on a large scale also without producer during production, is readily produced.
Convenient disassembly of the present invention, and it is simple to operate, it is only necessary to the connector of syringe needle is aligned between connecting tube and sleeve pipe
Space, then connector is tightened on sleeve pipe.The syringe of the present invention will not installed as ordinary syringe
When need syringe needle clamping firmly, make syringe needle installation loosely so as to cause firmly to kick the beam, or overexert and cause easily to hurt
Finger.
The agent structure (syringe needle and syringe and push rod) of the present invention is not right with existing very nearly the same with ordinary syringe
The structure of syringe has larger change, maintains the shape of the original simple structure of syringe substantially, is injected after avoiding improvement
Device is complicated and the defects of cause versatility and not strong practicality, production also very simple of getting up is convenient.
Further, in preferred embodiments of the present invention, the surface of above-mentioned needle tubing is provided with length scale.
The syringe needle of the present invention is provided with scale also on needle tubing, and medical personnel can be by according on needle tubing when being punctured
Scale judge or control the depth punctured, very simple, conveniently, for the practice medical personnel of not abundant operating experience
For also extremely benefit from, it is practical.
Further, in preferred embodiments of the present invention, above-mentioned syringe also includes being arranged at the push handle at cartridge openings,
Push handle stretches out in the opening of cylinder, and push handle includes first side and the second side being oppositely arranged with first side,
The outer surface of first side and cylinder connects, and first side is provided with the inner surface company of anti-slop serrations, second side and cylinder
Connect.
The present invention is provided with anti-slop serrations also in the push handle of syringe, in injection, it is possible to increase grasping of the finger to syringe
Power, so as to carry out more stable injection operation, it can avoid skidding because of sweat on hand.
Further, in preferred embodiments of the present invention, above-mentioned push handle is laminated structure.
Further, in preferred embodiments of the present invention, above-mentioned push rod includes sealing gasket, the body of rod and press section, sealing
Pad is arranged in cylinder and the outer wall of sealing gasket contacts with the inwall of cylinder, and one end of the body of rod is connected with sealing gasket, the body of rod
The other end is connected with press section.
Further, in preferred embodiments of the present invention, above-mentioned press section is arc-shaped flaky structure, press section include with
The convex surface of the end face connection of the body of rod and the concave surface for finger pressing.
In order to further improve the convenience that syringe uses, the present invention is used for finger pressing (or pushing) by press section
Press surface be arranged to concave surface, it can be bonded with thumb well, during push rod, can more smoothly push away
Drugs.
Further, in preferred embodiments of the present invention, the concave surface of above-mentioned press section is provided with anti-slop serrations.
The anti-slop serrations that the present invention is set on the concave surface of press section can increase the frictional force between thumb and push rod, and push is more
Add steady.
The syringe of the present invention is identical with common disposable syringe material.
The invention has the advantages that：
1st, simple structure of the present invention, it is easy to use, patient burden will not be increased, it is practical, it can produce in batches, it is economical
Value is high.
2nd, the present invention is by the threaded connection between sleeve pipe and connector, and compression resistance is strong, and syringe needle also will not when pushing hard medicine
Come off.
3rd, syringe of the invention can be general with the syringe needle of existing Clinical practice syringe needle and transfusion device front end, is easy to clinic and pushes away
Wide application.
4th, the present invention is convenient for production, production cost is low.
