    摘要: An administration set is configured to couple to a control module of a peristaltic infusion pump. The set can include a pressure plate and a peristaltic tube. The pressure plate can have attachment features structured to mate with corresponding attachment features of the control module such that the pressure plate is maintained in a fixed position relative to the control module. The peristaltic tube can include a first portion having first inner and outer diameters, a second portion downstream of the first portion having second inner and outer diameters, and a transition portion between the first and second portions. The peristaltic tube can be located along the pressure plate and positioned such that when the attachment features of the pressure plate and control module are mated, an expulsor of the control module engages the first portion and an air- in-line detector of the control module engages the second portion.

    摘要: The invention provides an infusion pump that allows a health-care professional to avoid, through a visual check, installing an infusion tube in an incorrect installation direction during installation of the infusion tube and that enables the drug to be correctly delivered from upstream side to downstream side of the infusion tube along a preset delivery direction. An infusion pump 1 in which an infusion tube allowing a drug 171 in a drug containing bag 170 to be infused to a patient P is installed in a lateral direction (horizontal direction or X direction) and in which a delivery driving unit 60 applies peristaltic motion to the infusion tube 200 to deliver the drug 171 in a delivery direction T preset along the lateral direction. The infusion pump 1 has a tube installation unit 50 in which the infusion tube 200 is installed in the lateral direction, and the tube installation unit 50 includes an infusion tube set direction display unit 150 that displays an upstream side 200A and a downstream side 200B of the infusion tube 200.

    摘要: A drug delivery device (100) for estimating the amount of free air in a cartridge (1) comprising a cartridge receiving portion (not shown) adapted to receive a cartridge (1), the cartridge (1) comprising a body portion (6), an axially displaceable piston (5), and a distal outlet portion (4), an expelling assembly comprising an axially displaceable piston drive member (10) adapted to interface with the proximal piston (5) portion of a received cartridge (1), the piston drive member (10) is adapted to be moveable in a distal direction, and to thereby pressurize the drug in a received cartridge. The drug delivery device further comprises means for measuring and acquiring a property relating to a fluid pres-sure of the drug in a received cartridge (1), and where the property depends on the amount of free air (7) contained in the cartridge (1). The drug delivery device further comprises means (20) for measuring and acquiring the position of the piston rod drive member (10), and means (40) for measuring and acquiring the time. The drug delivery device further comprises means (30) for storing, and means (31) for processing the acquired measurements. The processing means are configured for estimating the amount of air (7) in the cartridge (1).
