Document Type and Number:
WIPO Patent Application WO/2015/102078
Kind Code:
A1
Abstract:
An objective of the present invention is to achieve both avoidance of contamination and overall reduced device size when channeling a drug. Provided is an infusion set (2), comprising: a connection part (4) which is capable of being connected with an infusion bag (B1); a channeling part (5) for channeling a drug which is received from the infusion bag (B1) via the connection part (4); a conduit (6) which is disposed between the connection part (4) and the channeling part (5) so as to guide the drug from the connection part (4) to the channeling part (5); a pump (11) comprising connection conductors (15), a piezoelectric element (14) which repeatedly extends and contracts by drive voltages which are supplied via the connection conductors (15), and a diaphragm (13) which oscillates by the extension and contraction of the piezoelectric element (14), said pump (11) imparting to the drug a force for channeling the drug through the channeling part (5) in response to the supply of the drive voltages; and a drug delivery part (7) for detachably mounting a control device (3), which is for supplying the drive voltages to the pump (11), in a state wherein the control device (3) and the connection conductors (15) are electrically connected.
