IV flow controller having flushing feature

摘要

Provided is an IV flow controller which adjusts the amount of an IV material supplied to a patient through an IV tube and to which a flushing feature is added. The IV controller according to the present invention includes: a first body unit, a second body unit, a fixed roller, and a driving roller. The fixed roller is fixedly and rotatably arranged, and has a first gear unit and a second gear unit. The driving roller is accommodated such that a portion thereof is exposed, and the driving roller is moved along the lengthwise direction while controlling the flow of the IV when the exposed portion is turned. Also, in the flushing position, the driving roller rotates in cooperation with the first gear unit of the fixed roller across the IV tube so as to flush the latter. The second gear unit of the fixed roller may be configured so as to have a ratchet gear, and the second body unit has a pawl which meshes with the ratchet gear of the fixed roller in order to prevent reverse rotation. According to the present invention, flushing in the reverse direction is prevented by the ratchet gear, and thus medical accidents caused by reverse flushing can be prevented.

主权项

1. An IV flow controller having a flushing feature, comprising:
a first body unit which includes a bottom surface part and a wall surface part, with an open space being formed at the opposite side of the wall surface part, the first body unit further including a tube pressing surface and a fixed roller groove; a second body unit which is secured to the first body unit and forms a space through which an IV flow tube passes, in a longitudinal direction between the second body unit and the first body unit, the second body unit including a tube pressing surface and a fixed roller groove; a fixed roller which is rotatably fixed since a shaft is inserted in the fixed roller groove of each of the first body unit and the second body unit and includes a first gear unit, and a second gear unit formed of a latchet gear; and a driving roller which is configured in such a way that part of the driving roller is accommodated between the first body unit and the second body unit, while being exposed toward the open space, and when the exposed portion is rotated, the flow of the IV solution is regulated since the degree when an IV flow tube is pressed against the tube pressing surface varies while moving along the longitudinal directions of the first body unit and the second body unit, and the flushing is performed at a flushing position of an end portion of one side moving along the longitudinal direction since the driving roller rotates in cooperation with the first gear unit of the fixed roller with the IV flow tube being disposed between the first gear unit and the driving roller, wherein the second body unit includes a pawl which is engaged with the latchet gear for thereby preventing reverse rotation.
