    • 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.
    • 提供了一种IV流量控制器,其通过IV管调节供应给患者的IV材料的量并且加入冲洗特征。 根据本发明的IV控制器包括:第一主体单元,第二主体单元,固定辊和驱动辊。 固定辊固定地且可旋转地布置,并且具有第一齿轮单元和第二齿轮单元。 驱动辊被容纳成使其一部分露出,并且驱动辊沿着长度方向移动,同时在暴露部分转动时控制IV的流动。 此外,在冲洗位置,驱动辊与固定辊的第一齿轮单元一起跨越IV管旋转,以冲洗其。 固定辊的第二齿轮单元可以构造成具有棘轮,并且第二主体单元具有与固定辊的棘轮啮合的棘爪,以防止反向旋转。 根据本发明,通过棘轮防止反向冲洗,从而可以防止由反向冲洗引起的医疗事故。
