Title:
蠕動ポンプ
Document Type and Number:
Japanese Patent JP4685816
Kind Code:
B2
Abstract:
A method for operating a peristaltic pump (10) is provided. The peristaltic pump comprises a molded flow channel (26) contained on an elastomeric sheet (20) that is bonded or mechanically attached to a rigid substrate (22). The pump head rollers (16) are mounted radially from the axis of rotation (24) of the pump motor (12) and compress the clastomeric flow channels against the rigid substrate. During reflux, the pump head is positioned so that at least one of the rollers is parked in a position to compress the elastomeric flow channel at the input end of the peristaltic pump. Such an operation minimizes the amount of the elastomeric sheet that is exposed to high transient pressures.
