Description

A MEDICAL SYRINGE

The present invention relates to a medical syringe, and more particularly, to a medical syringe capable of simultaneous removal of body fluids and injection of a therapeutic agent even in a single scan operation in the treatment of a tongue such as a ganglion.

The ganglion is a positive scab resulting from the swelling of jelly-like liquid in the thin film of the joint. In addition to the wrist, the gonadal tendon often occurs in joints with large movements such as the shoulder and back of the hand, palms, fingers, ankles, and toes, or in adjacent areas of the tendon around the joints, and rarely in the nerves or wrists.

When the ganglion develops, there is a tingling or stinging pain in the area where the ganglion develops and its surroundings. For example, wrist ganglion can cause severe pain when breaking a wrist, putting on the floor, lifting a heavy object, and so on. Treatment of wrist ganglion is a method of suctioning a ganglion with a syringe or a method of extruding a ganglion by externally compressing it. Surgical treatment also treats wrist ganglion with an incision.

Treatment of ganglion using a syringe is carried out by injecting a therapeutic agent after sucking the contents such as jelly in the syringe with a syringe. In the course of these treatments, syringes for extracting body fluids from the scrotum and injecting therapeutic agents are used separately. Thus, when a syringe for fluid removal and a syringe for injecting a therapeutic agent are used separately, the clinician must stab the injection needle twice or more in the human body, and the patient must suffer from the pain caused by the injection of the syringe more than once .
