Description

Novel four-limb joint injector

Technical Field

The utility model relates to the technical field of medical instruments, in particular to a novel four-limb joint injector.

Background

Joint penetration is the treatment of joint diseases by injecting drugs into the joint cavity using a syringe. Clinically, joint treatment was performed as follows: in the joint injection treatment process, a doctor firstly injects local anesthetic, then leaves the needle head in the joint clearance, changes the injection needle cylinder, and then injects therapeutic medicine. However, in the special injector in the prior art, a doctor can only hold the tail of the needle head to replace the syringe, and the process easily pollutes the connection part of the tail of the needle head and the syringe, so that the infection probability of a patient is increased. Moreover, the metal needle portion of the prior art syringe is not marked with graduations and cannot determine depth of penetration after penetration into the patient's joint space (or skin tissue). And the connection part between the metal needle head and the injector in the prior art is in plug-in connection, and the connection part is easy to fall off in the process of injecting medicine.

Therefore, a new type of injector for the joints of the limbs is needed.

Disclosure of utility model

The utility model aims at overcoming the defects in the prior art and provides a novel four-limb joint injector.

In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

A novel extremity joint injector, comprising: a barrel assembly, a needle assembly, and a connector; the needle head assembly comprises a scale mark and a needle head; the needle head is provided with the scale marks, and the tail part of the needle head is provided with a handheld handle; the barrel assembly is detachably connected to the needle assembly by the connector.

Preferably, the shape of the handle is a single-wing butterfly.

Preferably, the syringe assembly comprises: a medicament shell and a push rod; wherein, a cavity is arranged in the medicament shell, and the push rod is movably arranged in the cavity of the medicament shell; the inner diameter of the cavity of the medicament shell corresponds to the outer diameter of the push rod.

Preferably, scale marks are arranged on the outer wall of the medicament shell.

Preferably, the needle assembly tail length is 2.5cm.

Preferably, three scale marks are arranged on the needle head, the origin of each scale mark is positioned at the tip end of the needle head, and the positions of the scale marks are 3cm, 4cm and 5cm.

Preferably, the connecting piece comprises a first connecting piece and a second connecting piece; wherein the first connecting piece is arranged at the tail end of the needle head assembly, and the second connecting piece is arranged at the front end of the needle cylinder assembly; the first connecting piece and the second connecting piece are in threaded fit connection.

Compared with the prior art, the utility model has the following technical effects:

(1) The hand-held handle on the needle can avoid needle pollution when medical staff changes the needle, reduce the incidence of infection in operation and facilitate the operation of the medical staff.

(2) The needle head is provided with the scale marks, so that medical staff can observe the position of the needle head entering human tissues more conveniently.

(3) The connecting piece is connected with the needle cylinder assembly and the needle head assembly, so that the connection of the needle cylinder assembly and the needle head assembly is firmer, and the risk of falling off of the injection needle cylinder is reduced.
