Technical Field

The invention relates to an injector, in particular to an adjustable injector, and belongs to the field of medical equipment.

Background

Syringes are common infusion therapy devices for hospital care personnel. When in use, the injector sucks medicine and then injects the medicine into the body of a patient through the needle, however, the existing injector has a simple structure, when a plurality of medicines are required to be injected into the same patient, different injectors are required to be replaced, and the operation is troublesome, so that the pain of the patient is increased.

Disclosure of Invention

Aiming at the problems in the prior art, the invention aims to provide an adjustable injector which can inject a plurality of compound medicines for a patient in one operation according to the requirement, is simple to operate and can also relieve the pain of the patient.

In order to achieve the purpose, the invention adopts the technical scheme that: an adjustable injector comprises an injection needle cylinder, wherein the wall of the injection needle cylinder is provided with a plurality of medicament storage containers, the medicament storage containers are communicated with the injection needle cylinder and used for introducing medicaments into the injection needle cylinder and mixing the medicaments with the medicament in the injection needle cylinder, the front end of the injection needle cylinder is provided with a needle head, and an opening at the rear end of the injection needle cylinder is inserted with a push rod.

Before injection, the medicines are respectively loaded in the medicine storage containers according to requirements, the medicine storage containers are installed on the wall of the injection needle cylinder, the push rod is pulled backwards to suck the other medicine into the injection needle cylinder, after the multiple medicines are mixed in the injection needle cylinder, the needle head is inserted into a patient, and the push rod is pushed to inject the medicines into the patient.

Preferably, the medicament storage container is made of PVC plastic. The PVC plastic is transparent, so that the injection dosage can be observed conveniently during operation.

The operation is influenced by the excessive quantity of the medicament storage containers, preferably, the quantity of the medicament storage containers is two, the medicament storage containers are distributed on the outer wall of the injection needle cylinder in a surrounding manner, two medicaments can be placed in the two medicament storage containers, and one medicament in the injection needle cylinder is added, so that three medicaments can be injected simultaneously.

Preferably, the medicament storage container is connected with the wall of the injection syringe through a threaded port. The threaded port connection is convenient for disassembling and replacing different medicament storage containers.

The design of the invention can inject a plurality of compound medicines for the patient in one operation according to the treatment requirement, has simple operation, reduces the working pressure of medical care personnel, does not need to inject for many times, and reduces the pain of the patient.

Drawings

FIG. 1 is a schematic structural view of the present invention;

in the figure, 10 is a syringe, 20 is a medicament container, 11 is a needle, 12 is a push rod.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in the figures, the adjustable injector comprises an injection needle cylinder 10, wherein a plurality of medicament storage containers 20 are arranged on the wall of the injection needle cylinder 10, the medicament storage containers 20 are communicated with the injection needle cylinder 10 and used for introducing medicaments into the injection needle cylinder 10 and mixing the medicaments with the medicament in the injection needle cylinder 10, a needle 11 is arranged at the front end of the injection needle cylinder 10, and a push rod 12 is inserted into an opening at the rear end of the injection needle cylinder 10.

Before injection, the medicines are respectively arranged in the medicine storage containers 20 according to requirements, the medicine storage containers 20 are arranged on the wall of the injection syringe 10, the push rod 12 is pulled backwards to suck the other medicine into the injection syringe 10, after a plurality of medicines are mixed in the injection syringe 10, the needle 11 is inserted into a patient, and the push rod 12 is pushed to inject the medicines into the patient.

Preferably, the medicament storage container 20 is made of PVC plastic. The PVC plastic is transparent, so that the injection dosage can be observed conveniently during operation.

The operation is influenced by the excessive number of the medicament storage containers 20, preferably, the number of the medicament storage containers 20 is two, the medicament storage containers 20 are circumferentially distributed on the outer wall of the injection syringe 10, two medicaments can be placed in the two medicament storage containers 20, and one medicament in the injection syringe 10 is added, so that three medicaments can be injected simultaneously.

Preferably, the medicament container 20 is connected to the wall of the syringe 10 through a threaded port. The threaded port connection facilitates removal and replacement of different medicament storage containers 20.
