PERISTALTIC PUMP

摘要

A peristaltic pump includes a mounting concave section 8a on which a peristaltically-actuated tube connected to an arterial blood circuit is mountable; a roller which compresses the peristaltically-actuated tube mounted on the mounting concave section in a radial direction and causes the peristaltically-actuated tube to be peristaltically actuated in a longitudinal direction such that a liquid therein is flowable in the arterial blood circuit; a load sensor that is able to detect displacement of the peristaltically-actuated tube 1a mounted on the mounting concave section in the radial direction; and blockage detecting means that is able to detect a blockage of the arterial blood circuit based on the displacement detected by the load sensor.

1. A peristaltic pump comprising:
a mounting concave section on which a peristaltically-actuated tube connected to a liquid flow route, through which a predetermined liquid is circulatable, is mountable; a peristalsis section which compresses the peristaltically-actuated tube mounted on the mounting concave section in a radial direction and causes the peristaltically-actuated tube to be peristaltically actuated in a longitudinal direction such that a liquid therein is flowable in the liquid flow route; displacement detecting means that is able to detect displacement of the peristaltically-actuated tube mounted on the mounting concave section in the radial direction; and blockage detecting means that is able to detect a blockage of the liquid flow route based on the displacement detected by the displacement detecting means.
