摘要:
An intravenous fluid pump (IV) contains a disposable part including a fluid chamber having a resilient top membrane and a non-disposable part including a piston abutting a resilient membrane and a vacuum chamber fitted on top of the resilient top membrane. An external pump is used to create vacuum in the vacuum chamber, resulting in the resilient top membrane being held taut. The flow rate through the pump is relatively independent of changes in the pressure of IV fluid on the upstream and the downstream due to changes in the relative elevation of the fluid reservoir and the patient with respect to the fluid pump.

A pinch clamp assembly for engaging a tube with an enteral feeding or infusion pump adapted to feed nutritionals or to infuse medical solutions to a patient, is provided comprising a base (1) comprising holding means (3) for holding a pumping section (10) of the tube in operative engagement with the base (1) and supporting means (5) for supporting a connector (6), a clamping element (7) having clamping surfaces engageable with the pumping section (10) and moveable between an open position allowing flow of fluid through the pumping section (10) and a closed position wherein the pumping section (10) is occluded by the clamping element (7), and locking means adapted to engage with each other in the closed position and adapted to interact with releasing means external to the pinch clamp assembly so as to bring the clamping element (7) from the closed to the open position, a connector (6) for connecting the tube with a port on a patient, the connector (6) being removable from the pinch clamp assembly, the clamping element (7) further comprising a retaining lever (16), wherein in the open position of the clamping element (7) the connector (6) is retained by the retaining lever (16), and wherein the clamping element (7) is adapted to engage with the releasing means (43) to release the clamping element (7) to the open position when the pinch clamp assembly is mounted to the enteral feeding or infusion pump and the connector (6) is removed.
摘要:
The present invention is directed to a valve that has an orifice closing member adjacent to an orifice through which fluid can flow, a displacement member having a first portion and a second portion, where the first portion is adjacent to the orifice closing member when the valve is in an open position, a first magnet and a second magnet where the first and second magnets are sufficiently proximate to the displacement member to exert a magnetic force on the displacement member, and an actuator for generating a magnetic field to move the displacement member toward the first magnet, cause the first portion to press against the orifice closing member, and cause the orifice closing member to close the orifice.

An apparatus for carrying out selected fluid management and/or renal replacement patient therapy is characterized by an interactive operator control system having operator inputs for selectively changing a panel kit, replacing a filter cartridge, and/or changing to a different patient therapy during a currently running patient therapy, and providing operator instructions for carrying out tasks for completing same. In one embodiment, the interactive operator control system is also characterized by automatically serially identifying different setup steps to be carried out during system setup, displaying the successive steps substantially throughout the system setup as well as displaying on the operator interface screen sequential tasks to be carried out for each of the different setup steps.

摘要:
Die vorliegende Erfindung betrifft ein Verfahren zur Überprüfung und/oder Überwachung der Dichtigkeit mehrerer pneumatisch oder hydraulisch betätigter Aktoren einer Maschine, insbesondere mehrerer Ventilaktoren einer medizinischen Behandlungsmaschine, wobei die Aktoren während des Betriebs der Maschine in unterschiedlichen Kombinationen mit Druck beaufschlagt werden, wobei für mehrere unterschiedliche Kombinationen von mit Druck beaufschlagten Aktoren der während einer stationären Betriebsphase an den in der jeweiligen Kombination mit Druck beaufschlagten Aktoren gemeinsam auftretende Druckabfall gemessen wird und wobei für einzelne Aktoren und/oder einzelne Gruppen von Aktoren jeweils ein Dichtigkeitswert ermittelt wird, in welchen der für jene Kombinationen gemessene Druckabfall eingeht, in welchen der jeweilige Aktor und/oder die jeweilige Gruppe von Aktoren mit Druck beaufschlagt wurde. Weiterhin umfaßt die Erfindung eine Maschine, insbesondere eine medizinische Behandlungsmaschine, mit einer entsprechenden Ventilaktorüberwachung.
摘要:
The invention relates to a method for actuating valves for controlling a flow path of especially a medical treatment machine, comprising a plurality of processes for establishing flow paths by actuating a group of valves, every process requiring a group of valves that are suitable for carrying out said process, so that other processes cannot change the switched state of said valves, and every process deciding on the release of the valves required by it. The invention further relates to a method for monitoring the actual and/or planned state of a plurality of valves in the control of a flow path of an especially medical treatment machine. Said method comprises the following steps: determining the actual and/or planned switched state of the valves, determining the connections resulting from the switched state of the valves, comparing the resulting connections to a predetermined plurality of inadmissible connections. The invention further relates to machines, especially medical treatment machines, which comprise corresponding valve or valve actuator controls.
