Description

A double syringe {A DOUBLE SYRINGE}

The present invention relates to a double syringe, and more particularly, to a double syringe capable of simultaneous removal of body fluid and injection of a therapeutic agent even in a single scanning operation.

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.
