Device for cutting, separation, and discharge of syringe

A device for cutting, separation, and discharge of a syringe, the device comprising:

• a barrel unit into which a syringe is insertable and which has a needle portion through-hole provided to allow only a needle portion to be cut to pass through a lower end thereof;
• a main body including
• an upper shell which has a first groove,
• a lower shell which has a second groove corresponding to the first groove and is coupled to the upper shell, and
• a driving unit which is provided between the upper shell and the lower shell and is directly coupled to the barrel unit, which is installed through the first and second grooves, to rotate the barrel unit at a predetermined angle;
• and
• a cutting body which is detachable from a lower portion of the main body and includes a cutting blade to cut the needle portion during rotation of the barrel unit,
• wherein
• the barrel unit, the main body, and the cutting body are configured such that transfer of the inserted syringe, cutting of the needle portion, discharge of the cut needle portion, and discharge of a syringe main body from which the needle portion is removed are performed by only one rotation of the barrel unit,
• the cutting body includes:
• a detachable body which is detachable from the lower portion of the main body by sliding through a detachment groove provided in the lower portion of the main body;
• a curved groove which is provided in an upper portion of the detachable body and formed to be curved and concave along a direction of rotation of the barrel unit while facing a lower end of the barrel unit, the curved groove being curved and concave away from the lower end of the barrel unit in a vertical direction;
• an arc-shaped slot which is provided along the direction of rotation of the barrel unit through the curved groove and configured to allow the needle portion of the syringe inserted into the barrel unit to pass therethrough;
• and
• a cutting blade which is provided at a tip of the arc-shaped slot and configured to cut the needle portion in response to the needle portion rotating in conjunction with the rotation of the barrel unit in a state of passing through the arc-shaped slot.
