20150190628 | IV Flow Controller Having Flushing Feature - 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. | 07-09-2015 |
