Abstract

The present invention provides a liquid medicine injection apparatus capable of injecting an additional fluid after completion of liquid medicine injection. A liquid medicine injection apparatus capable of injecting an additional fluid after completion of liquid medicine injection according to an embodiment of the present invention comprises: a cylinder lengthily extending in one direction and having a nozzle formed at one end thereof; a piston installed inside the cylinder to be movable in an airtight manner along the one direction and being capable of forming a liquid medicine storage spacewhich is filled with the liquid medicine introduced through the nozzle; an injector moving the piston and disposed at the other end of the cylinder; a fluid tank storing a fluid in a sealed state, disposed movably inside the cylinder so as to be movable with the piston, and being deformable by a pressure; a needle unit disposed between the nozzle and the fluid tank and passing through a part of the fluid tank to enable communication therebetween; and a cap member disposed between the needle unit and the fluid tank and being deformable to allow the needle unit to pass through the fluid tank.

Description

technical field [0001] The present invention relates to a liquid medicine injecting device capable of injecting an additional fluid after liquid medicine injection is completed, and more particularly, relates to a device capable of sequentially injecting a second liquid medicine after a first liquid medicine is injected into a patient's body, or capable of A liquid medication infusion device that flushes with additional fluid after liquid medication has been injected into the patient so that no fluid remains in the device and / or tubing. [0002] For example, the present invention relates to a liquid medicine injecting device implemented as a single device capable of performing the following functions: in the case of sequentially administering two liquid medicines to a patient to enhance the curative effect, After the injection is completed, the second liquid medicine is injected sequentially. [0003] Further, the present invention relates to a liquid medicine injection devic...
