Abstract

The invention provides a transfusion apparatus and a method for detecting bubbles and achieving miniaturization of the transfusion apparatus. The transfusion apparatus according to an embodiment includes a finger-type pump mechanism, the finger-type pump mechanism including a plurality of fingers, the plurality of fingers and a holding member sandwiching a passage composed of a flexible material, the holding member being arranged to face the plurality of fingers in an opposed manner, the finger-type pump mechanism depressing and elastically deforming a side face of the passage by a peristaltic motion reciprocating the plurality of fingers to send a liquid with which the passage is filled, the transfusion apparatus comprising: a pressure sensor provided to at least one of the plurality of fingers or the holding member; and a determination unit that determines presence or absence of bubbles in the passage based on pressure detected by the pressure sensor when a finger is depressing the passage.

Description

technical field [0001] The invention relates to an infusion device and a bubble detection method in the infusion device. Background technique [0002] In a medical infusion device, a technique for detecting air bubbles mixed in a tube (infusion tube) for transporting a drug solution is disclosed. For example, in Patent Document 1, the infusion pump sequentially presses the infusion tube (peristaltic type) or presses (piston type) a part of the infusion pump to deliver and detects air bubbles present during the infusion. In this infusion pump, an air bubble detector using an ultrasonic sensor is provided in the infusion pump, whereby air bubbles can be detected with high accuracy. [0003] Patent Document 1: Japanese Patent Laid-Open No. 2000-325476 [0004] However, in the technique described in Patent Document 1, since it is necessary to secure a dedicated space for installing a bubble detector using an ultrasonic sensor in the infusion device, there is a problem in terms...
