Patent number: 4988337Abstract: Disclosed is a syringe pump apparatus adapted to have a syringe mounted thereon so as to supply in a specified amount per specified unit of time an aqueous solution such as medication within the syringe. A first shaft is fixed to a slider for causing a piston portion of the syringe to operate. Between this slider and a drive motor there are provided a block and a second shaft, the block being provided with an overload detecting mechanism. When the movement of the slider is forcedly stopped during a time period in which the slider is being moved through driving of the drive motor, the resulting load is transmitted to the first shaft in response to the forced stoppage of the slider. In accordance with this load, the overload detecting mechanism detects the state of overload of the slider. Then, when the value detected has exceeded a specified value, the drive motor is stopped by a drive halting mechanism.Type: GrantFiled: August 8, 1989Date of Patent: January 29, 1991Assignee: Terumo Kabushiki KaishaInventor: Yoshio Ito
