Balloon type liquid medicine injector

Abstract

Disclosed is a balloon type liquid medicine injector for continuously inject a small amount of liquid medicine into a body of a patient so as to be easily assembled and prevent an unnecessary dead space while being inflated after a liquid medicine is injected, so as to be miniaturized. When a tube body is provided outside a fixed pipe, both ends of the tube body are folded and inserted into both ends of the fixed tube, to remove the dead space while being inserted inside the case. In addition, in a state where the both ends of the tube body are folded and inserted into the both ends of the fixed tube, an injection mechanism for injecting the liquid medicine or a stopper mechanism are coupled while pressing the tube body folded inward, so that a separate packing is unnecessary and the airtightness is maintained. In addition, the injector and the plug device are connected and fixed to the injection device through the plug device from the outside of the shell by using a locking device, sothat not only the injection device and the plug device are fixed, but also the fixation between the injection device and the plug device and the shell can be realized synchronously.

Description

technical field [0001] The present invention relates to a balloon type medicinal liquid injector, which is used to continuously inject a small amount of medicinal liquid into the patient's body, more specifically, a balloon type medicinal liquid injector, which is not only easy to assemble, but also expands when the medicinal liquid is injected. There is no unnecessary dead space (Dead Space) in the state, so that miniaturization can be realized. Background technique [0002] Often, people who have had emergency surgery, such as cancer or leukemia, continue to receive medications such as antibiotics or pain relievers after surgery to eliminate inflammation and reduce their pain. [0003] Although these liquid medicines vary from patient to patient, depending on the patient, if the appropriate amount is exceeded or less than the appropriate amount, another dangerous situation may be brought to the patient. [0004] Therefore, in order to solve such problems, a separate injec...

Problems solved by technology

[0011] However, fixing the injection device or the stopper device to the fixed tube while maintaining airtightness requires the use of other packing devices, etc., and due to the use of such packing devices, etc. Other defect problems, or cause various difficulties
