摘要:
A system and method for locking a door. An assembly has a first engagement surface. A door is coupled to the assembly, the door including a latch member having a second engagement surface for engaging the first engagement surface. A movable member is capable of generating a force against at least one of the assembly and the door to press together and substantially prevent disengagement of the first engagement surface and the second engagement surface.

A system, device, and method for mixing a substance with a liquid pumps the liquid into a container of the substance to produce a solution. The container may be part of a container assembly including a port assembly for coupling with the container to produce an inlet and/or and outlet port for the container. The container assembly may be received within a receiving chamber for causing the coupling. The solution may be permitted to flow out of the outlet port when the solution rises within the container to a level of the outlet port so that the substance is partially diluted before flowing out of the outlet port.

An occluder, and methods for occlusion, that employs first and second opposed occluding members associated with each other, a tube contacting member connected to, or comprising at least a portion of, at least one of the first and second occluding members, and a force actuator constructed and positioned to apply a force to at least one of the first and second occluding members. Application of the force by the force actuator may cause the tube contacting member to move between a tube occluding and an open position. A release member may be configured and positioned to enable an operator to manually move the tube contacting member from the tube occluding position to the open position even with no force applied to the at least one of the first and second occluding members by the force actuator. In one embodiment, the force actuator may apply a force sufficient to bend both the first and second occluding members, so that upon application of the force by the force actuator (such as an air bladder), the first and second occluding members (e.g., spring plates pivotally connected at opposite ends) bend and the tube contacting member may move between the tube occluding and the open position.

A fluid handling cassette (24), such as that useable with an APD cycler device or other infusion apparatus, may include a generally planar body having at least one pump chamber (181) formed as a depression in a first side of the body and a plurality of flowpaths for fluid that includes a channel. A patient line port may be arranged for connection to a patient line (34) and be in fluid communication with the at least one pump chamber via at least one flowpath, and an optional membrane (15) may be attached to the first side of the body over the at least one pump chamber. In one embodiment, the membrane may have a pump chamber portion (151) with an unstressed shape that generally conforms to the pump chamber depression in the body and is arranged to be movable for movement of fluid in the useable space of the pump chamber. One or more spacers (50) may be provided in the pump chamber to prevent a pump membrane from contacting an inner wall of the pump chamber. Patient, drain (28) and/or heater bag lines (26) may be positioned to be separately occludable in relation to one or more solution lines (30) that are connectable to the cassette.
摘要:
A system and method for pumping fluid using a pump cassette. The system includes a control assembly for operating the pump cassette. A force assembly having a movable member is capable of applying force to the pump cassette to press the pump cassette against the control assembly. The movable member may be an expandable member, such as a bladder.

A sample carrier comprising a top wall, a base, and a support wall joining the top wall and the base. The top wall includes aligned, spaced-apart openings on at least one side of the support wall which are sized to receive sample tubes. Sleeves depending from the top wall and circumscribing each opening direct sample tubes into sample tube holding areas. The sample tube holding areas each include one or more retaining walls extending upward from the base opposite the support wall. Springs extending outward from the support wall bias sample tubes against the retaining walls. A drip shield comprising a cover plate, a pair of through-holes for accessing sample tubes in the sample carrier, and a depending fin which separates sample tubes on opposite sides of the support wall protects against cross-contamination between sample tubes held by the sample carrier.
