Description

Novel syringe

Technical Field

The utility model relates to a medical instrument especially relates to a novel syringe.

Background

Clinical injection is the most routine clinical procedure and syringes are the most commonly used medical devices. However, in the using process, when the needle head and the needle cap are tightly matched, the needle head and the needle cap are not separated, but the needle head is separated from the nipple of the needle cylinder, so that the separation is difficult, and the inconvenience is brought to the use. And meanwhile, most of injectors are disposable, and disposable injectors on the market cannot be guaranteed not to be recycled, so that potential safety hazards exist.

SUMMERY OF THE UTILITY MODEL

Aiming at the defects of the prior art, the utility model provides a novel injector.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a novel syringe includes syringe needle, cylinder, piston, the syringe needle with the nipple of cylinder cup joints, the piston includes rubber buffer, piston rod, piston handle, the piston rod is close to piston handle one end is provided with the pawl, the opening part of cylinder be provided with pawl assorted back-off.

In a preferred embodiment of the novel syringe provided by the present invention, the needle head is sleeved with a needle cap.

In a preferred embodiment of the novel syringe provided by the present invention, the bottom end of the needle head is umbrella-shaped, and the diameter of the bottom end is larger than the diameter of the needle cylinder.

In a preferred embodiment of the novel injector provided by the present invention, the bottom of the syringe is symmetrically provided with fixing rings capable of accommodating fingers.

In a preferred embodiment of the novel syringe provided by the present invention, the inner side of the fixing ring and the bottom of the piston handle are covered with an anti-slip material.

Compared with the prior art, the utility model provides a pair of novel syringe's beneficial effect is: the disposable syringe needle has the advantages that the disposable syringe needle is truly realized, the syringe needle cannot be reused after being used up, the design of the syringe needle can better realize the separation of the syringe needle and the syringe cap, and the use is convenient.

Drawings

In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the drawings used in the description of the embodiments are briefly introduced below, and it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained without inventive work, wherein:

fig. 1 is a schematic structural diagram of a novel syringe.

In the figure: 1. a needle head; 2. a needle cylinder; 3. a piston; 4. a nipple; 7. a rubber plug; 8. a piston rod; 9. a piston handle; 10. chamfering; 11. reversing; 12. a needle cap; 13. and (4) fixing the ring.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1, the novel syringe comprises a needle 1, a syringe 2 and a piston 3, wherein the needle 1 is sleeved with a nipple 4 of the syringe 2, the piston 3 comprises a rubber plug 7, a piston rod 8 and a piston handle 9, one end of the piston rod 8 close to the piston handle 9 is provided with a pawl 10, and an opening of the syringe 2 is provided with a reverse buckle 11 matched with the pawl 10.

The needle head 1 is sleeved with the needle cap 12, so that the needle head 1 can be protected, and the needle head 1 is convenient to treat after being used.

The bottom of the needle head 1 is umbrella-shaped, the diameter of the bottom end of the needle head is larger than that of the needle cylinder, when the needle cap 12 is matched with the needle head 1 tightly, the umbrella-shaped bottom end of the needle head 1 can be pressed, the needle cap 12 is convenient to separate from the needle head 1, and the use is more convenient.

The fixing rings 13 capable of accommodating fingers are symmetrically arranged at the bottom of the needle cylinder 2, so that the single-hand operation of medical staff is facilitated.

The inner side of the fixing ring 13 and the bottom of the piston handle 9 are covered with anti-slip materials, so that slipping between hands and the syringe can be prevented, and pain of a patient is increased.

During the use, take off needle cap 12 stretches into the medicament bottle with syringe needle 1 in, through carrying and drawing piston 3 absorbs the injection, when accomplishing the injection, pawl 10 can block into back-off 11 is inboard to make 3 auto-locks of piston can't reverse removal again, realize the disposable in the true sense.

The above only is the embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structures or equivalent processes made by the present specification can be changed, or directly or indirectly applied to other related technical fields, and all the same principles are included in the protection scope of the present invention.
