| 摘要 |
The invention provides a flow rate stabilizer for a peristaltic pump having at least one pressure-applying member (8), including pressure-applying means for applying pressure to a tubing portion (6) in addition to the pumping pressure applied thereto by the pump, the additional pressure to the tubing portion (6) being substantially perpendicular to the direction of the action of the pumping pressure, causing the tubing portion (6) to retain its original cross section or to return thereto, the pressure applied by the member (8) and the pressure applied by the pressure-applying means being applied sequentially so that at least some of the tubing portion upon which the pressure-applying member (8) operates, is alternately subjected to both pressures during the pumping period, whereby the flow rate in the tubing is stabilized, ensuring the filling of the entire original volume of the tubing (6) with fluid and preventing a decrease in the volume of the tubing portion (6) during the operation of the pump. |
