摘要:
A peritoneal dialysis system includes first and second concentrate sources in selective fluid communication with a medical fluid pumping cassette, the first and second concentrate sources holding first and second peritoneal dialysis concentrates, respectively; a pump actuator configured to cause the medical fluid pumping cassette to pump the first and second concentrates; and a processor and memory configured to (i) determine a cumulative volume of at least one of the first or second peritoneal dialysis concentrates pumped from the medical fluid pumping cassette by the pump actuator, (ii) compare the cumulative volume to a threshold, and (iii) if the cumulative volume is outside of the threshold, modify a subsequent stroke volume of at least one of the first or second pump chambers actuated by the pump actuator in an attempt to cause an updated cumulative volume for the at least one peritoneal dialysis concentrate to be within the threshold.

Medical device assemblies having a connection mechanism for securely connecting a hub to fluid storage containers in a luer slip relationship are described. An exemplary medical device includes a hub forming a cavity, a second indicating element disposed within the cavity that engages the hub. Additional features of the medical device include a second indicating element contoured to form a line contact with the hub. In a specific configuration, the hub includes a first indicating element attached to the hub and extending proximally into the cavity having a protrusion. In a more specific configuration, the medical device includes a fluid storage container that has an indication system for visually indicating optimal fluid-tight engagement of the hub and the fluid storage container.

A connector system for a medical device includes a first connector having an elongate opening, and a second connector including a lock portion, where the first connector is movable relative to the second connector between an initial position where the first connector is not in fluid communication with the second connector and an activated position where the first connector is in fluid communication with the second connector. The system also includes a locking member connected to the first connector. The locking member is transitionable between an unlocked position where the second connector is movable within the elongate opening of the first connector and a locked position where the locking member is configured to engage the lock portion of the second connector to lock the first connector to the second connector in the activated position. The locking member comprises a spring body received by the elongate opening of the first connector.

Delivering a blood processing solution to blood in a blood bag includes coupling a first tube to a vented spike at one end and to a Y-shaped tube connector at a second end. An in-line microbiotic barrier filter is coupled to the first tube between its ends. A second tube is coupled to a transfer bag at one end and to the Y-shaped tube connector at its other end. A third tube is coupled to the output of the Y-shaped tube connector and sealed at its distal end. The blood bag includes a fourth tube that is sealed at a distal end. The third tube is welded to the fourth tube using a sterile tubing welder, wherein a functionally-closed, sterile flow path through which the blood processing solution can flow into the blood bag is maintained.

A male member (1) includes a tubular member (10) and a cover (20) covering at least a tip (11) of the tubular member. A lateral hole (14) that communicates with a flow path (13) is formed in an outer peripheral surface of the tubular member. The cover includes an outer peripheral wall (21) that can be deformed elastically by compression and a head part (23) that is provided at one end of the outer peripheral wall. The head part includes an interior cavity (24) into which the tubular member is inserted, and a slit (25) is formed in an innermost part (24a) of the interior cavity. In a state where the outer peripheral wall is not deformed by compression, an inner peripheral surface of the interior cavity contacts closely with the outer peripheral surface of the tubular member so as to block the lateral hole, and the tip of the tubular member and the innermost part of the interior cavity are spaced apart from each other. Thereby, it is possible to reduce an amount of a liquid substance adhering to outer surfaces of the cover and a female member after separation from the female member.

The present invention relates to a device comprising a capillary tube assembly (100) having a proximal (20) end and a distal (30) end, comprising: a think walled capillary tube shaft (10) disposed with a capillary lumen (12) extending from an open proximal (20) end to an open distal (30) end, and a fluidic adapter (40) at the proximal (20) end in fluid connection the capillary tube lumen (12), wherein the capillary tube shaft (10) is adapted for dismountable insertion into a fluid-carrying lumen (212) of a bodily invasive tube (200), and the adapter (40) provides fluidic access to the capillary tube lumen (12) that is fluidically isolated from access to the invasive tube lumen (212). It further relates to an applicator package comprising the capillary tube assembly (100) and an applicator (510).
摘要:
The connector for a fluid line of an extracorporeal circuit comprises a tubular body which internally defines a fluid passage, a first connection port predisposed for coupling to the fluid line, a second connection port predisposed for coupling to a male Luer connector borne by an external element, and a closure element of the second connection port. The closure element is formed of a breakable membrane made in a single piece with the tubular body. On coupling, the membrane is broken by the truncoconical projection of the male Luer connector. The connector connects a service line of an extracorporeal circuit to a pressure sensor of a dialysis machine.
