Abstract

1484394 Infusion apparatus ALZA CORP 17 Jan 1975 [4 Feb 1974] 2137/75 Heading A5R [Also in Divisions Fl and F2] A liquid infusion unit for continuous infusion of liquid drugs into a patient at a controlled rate comprises a housing 10 which is attachable to the patient by straps 14, 16 and which has a recess 90 on the side facing away from the patient; a cartridge assembly 200 for containing the liquid under pressure and which removably fits within said recess; a liquid flow path enclosed within the housing and which connects with the liquid outlet of said cartridge; an adjustable flow controller in said housing for regulating the flow rate in said flow path; and a conduit leading from the flow path to the infusion site. The unit has a generally crescent shaped transverse cross section having a concave support base 12 for engaging the patient and a convex upper surface. The flow path comprises a hollow needle 72 which is mounted on an element 70 having a cylindrical interior chamber 76 in communication with the hole 74 in the needle. A filter 80 is mounted in the chamber 76. A passageway 82 leads to two flexible parallel conduits 98 and 100 which lead to a chamber in a connecting block 108 having an outlet. Conduit 100 is closed by a spring 124 and may be opened by a tool 150 for bleeding the unit prior to use. Conduit 98 contains a plurality of longitudinally extending fibers. A wedge 128 is transversely slidably mounted between stops 130 and 132 and is acted on by a longitudinally movable control wedge 134 to squash conduit 98 between a wall 106 and wedge 128 to thus reduce the cross-sectional area inside conduit 98 and thereby control the flow of liquid. A rack gear 136 is provided on the control wedge, and this is operated by a pinion 152 on tool 150 which may be inserted through a hole 148 in the housing. A pointing arm 140 is provided to correspond with a scale 144 along the edge of an opening 146 in the housing. A flexible diaphragm is provided in the flow passage and this operates an indicator arm 164 having a flag 170 which may be seen through a aperture 172 in the housing to signal excess pressure in the event of a flow blockage downstream of the outlet. The cartridge 200 comprises outer shell halves housing a distendable bladder 212. The cartridge has a valve assembly 210 comprising a resilient member 214 having apertures and an end wall having a central aperture such that insertion of needle 72 through said aperture distends the resilient member allowing flow communication from the bladder via said apertures. The bladder has a gas permeable microfilter 220 which allows venting of gas during filling. A spider attached to the bladder has an indicating arm 228 which corresponds with a scale 232 on the outside of the cartridge. A locking lever 40 engages pins on the cartridge to hold it firmly in position.
