Abstract: Occlusion assemblies facilitating occlusion of flexible tubing are disclosed. Occlusion assemblies may be associated with or form part of a medical infusion device and may facilitate fluid handling by such devices. Occlusion assemblies may position and immobilize tubing. Occlusion assemblies comprise a tubing occluder constructed and positioned to apply a force to tube(s) to occlude the tubes. Occlusion assemblies may be configured to include a single tube in certain cases, and in other cases to occlude multiple tubes, whether an odd number of tubes or an even number of tubes. Occlusion assemblies may include automatic actuators and in certain cases also include a manual actuator to provide an override function. Occlusion assemblies may include safety features, for example, to prevent a release of occlusion force on the tubing and/or convenience features, for example a retainer mechanism to hold the tube occluder in a non-occluding position.

Abstract: A pump for administering an agent to a patient includes a housing, a syringe seat, and a bumper. The syringe seat is coupled to the housing. The bumper is coupled to the housing adjacent to the syringe seat.

Abstract: An improved floating rail system for mounting accessories on a firearm having a barrel including a chassis and a clamp adapted to attach the chassis about the barrel of the firearm. A plurality of elongate accessory mounting rails are attached to the chassis and extend parallel to an axis of the barrel. The accessory mounting rails are supported in the chassis radially spread apart from the barrel.

Abstract: A medical infusion fluid handling system, such as an APD system, may be arranged to de-cap and connect one or more lines (30) (such as solution lines) with one or more spikes (160) or other connection ports on a fluid handling cassette (24). This feature may reduce a likelihood of contamination since no human interaction is required to de-cap and connect the lines and spikes. For example, an APD system may include a carriage (146) arranged to receive a plurality of solution lines (30) each having a connector end (31a) and a cap (31). The carriage may move along a first direction so as to move the connector ends of the solution lines along the first direction, and a cap stripper (149) may be arranged to engage with caps on the solution lines on the carriage. The cap stripper may move in a second direction transverse to the first direction, as well as to move with the carriage along the first direction.

Abstract: An occluder (147), and methods for occlusion, that employs first and second opposed occluding members (165) associated with each other, a tube contacting member (161) connected to, or comprising at least a portion of, at least one of the first and second occluding members, and a force actuator (166) 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 (169) 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 occluding member by the force actuator.

Abstract: A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a cycler device (14) may include a heater bag receiving section (142) and a lid (143) mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of dialysate. A user interface (144) may be moveable to be received into the receiving section and covered by the Hd, if desired. The system may detect anomalous conditions, such as tilting of the system housing, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines (30) connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution.

Abstract: A two-component elastomeric enclosure surrounding a mechanical device can effectively attenuate the noise and vibration associated with the device. The outer shell of the enclosure comprises a castable polyurethane elastomer, while the inner shell of the enclosure comprises polymeric foam. The inner foam layer of the enclosure can contact both vertical and horizontal surfaces of the enclosed device in order to immobilize it within the enclosure, and to enhance the dampening effect of the enclosure on acoustic and mechanical vibrations. The enclosure can act as a vertical and horizontal supporting structure for the enclosed mechanical device. The enclosure may in turn be fastenable to a housing or frame member via relatively stiff elastomeric bushings, pads or mounts, in order to further reduce the transmission of vibrations originating from the mechanical device. The enclosure can be molded in a two-stage pour-molding process using a cavity mold and two forming dies—one for each layer of the enclosure.

Abstract: The present invention generally relates to occluders and, in particular, to occluders for use in medical infusion systems. In one aspect, the occluder contains one or more tubes through which fluid can flow, and the occluder can be automatically controlled to allow or at least partially prevent fluid flow. In some cases, the occluder may be constructed and arranged to fail (e.g., due to loss of power) in a “closed” position, i.e., a position that at least partially prevents fluid flow. In addition, in one embodiment, the occluder may be manually overridden, even when in a failed state, by a user. For instance, in the event of a power failure, a user may be able to manually override the occluder to remove tubing from the occluder. Such occluders may find use, for example, in medical devices such as hemodialysis machines, medical infusion pumps, plasmapheresis devices, and the like.
