Abstract
The present disclosure provides a drug discharge assembly including a drive piece linearly reciprocated along one direction, a rotating unit being in contact with an end of the drive piece and rotating in one direction according to a linear reciprocating motion of the drive piece, a flexible tube disposed adjacent to the rotating unit and having a curved section at least partially extending in a circumferential direction, and a pressing unit mounted on the rotating unit and rotating while pressing the tube according to a rotation of the rotating unit, and a drug injection device comprising the same.
Claims5
A drug discharge assembly comprising:
- a drive piece configured to be linearly reciprocated along one direction;
- a rotating unit in contact with an end of the drive piece and configured to rotate in one direction according to a linear reciprocating motion of the drive piece;
- a flexible tube disposed adjacent to the rotating unit and having a curved section at least partially extending in a circumferential direction;
- and
- a pressing unit mounted on the rotating unit and configured to rotate while pressing the tube according to a rotation of the rotating unit.
A drug injection device comprising:
- a needle assembly;
- a reservoir configured to store a drug discharged to the needle assembly;
- a drive module configured to linearly reciprocate a drive shaft;
- a drive piece connected to the drive shaft and configured to be linearly reciprocated according to a movement of the drive shaft;
- a rotating unit in contact with an end of the drive piece and configured to rotate in one direction according to a the linear reciprocating motion of the drive piece;
- a flexible tube disposed between the needle assembly and the reservoir and having a curved section at least partially extending in a circumferential direction;
- and
- a pressing unit mounted on the rotating unit and configured to rotate while pressing the tube according to a rotation of the rotating unit.
