A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engageable with the piston regardless of a rotational orientation of the piston relative to the plunger.

Syringe plunger

A pressure jacket for use with a fluid injector may have a pressure jacket body having a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a pressure jacket longitudinal axis. The pressure jacket may further have at least one resiliently deflectable retaining member having a first segment attached to the pressure jacket body and a second segment protruding from the first segment toward the distal end of the pressure jacket body and deflectable relative to the first segment. The pressure jacket may further have at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member may interact with a housing of the fluid injector when the pressure jacket is connected to the housing to deflect the at least one resiliently deflectable retaining member upon rotation of the pressure jacket.

System and method for fluid engagement with a pressure jacket and syringe cap

An adapter for releasably attaching a syringe to an injector. The adapter comprises a mounting mechanism positioned at a rear end of the adapter to mount the adapter in a desired position relative to a front wall of the injector; and a syringe carrier section adapted to seat at least a portion of the syringe. The syringe carrier section defines a first opening on a top thereof to allow placement of the syringe therein from the top and a second opening in a rear section thereof to allow the drive member of the injector to communicate forward force to the plunger. A cover portion extends over a rearward end of the first opening and has a first end configured to abut the flange of the syringe when the syringe is positioned within the syringe carrier section.

Injector systems and syringe adapters for use therewith

A plunger for use with a syringe has a plunger body with a proximal end, a distal end, and a circumferential sidewall extending between the proximal end and the distal end along a plunger longitudinal axis. The plunger further has at least one resiliently deflectable retaining member having a first segment attached to the plunger body and a second segment protruding toward the distal end of the plunger body and deflectable relative to the first segment. The plunger further has at least one actuation member associated with the at least one resiliently deflectable retaining member. The at least one actuation member interacts with a piston to deflect the at least one resiliently deflectable retaining member upon rotation of the plunger relative to the piston. The plunger is engagable with the piston regardless of a rotational orientation of the piston relative to the plunger.

A selector valve for a medical fluid delivery device is disclosed. The valve includes a valve bore in fluid communication with an outlet channel, first and second outlet ports, and a selector valve body which includes a valve stem located within the valve bore and having a flow passage. The selector valve body is adapted to place the flow passage in fluid communication with one of the first outlet port, the second outlet port, and a shut-off position. Further, the selector valve body includes a sealing arrangement having an elastomeric core disposed within a thin-walled valve stem which comprises a thin cylindrical sidewall in direct contact with the valve bore. When the elastomeric core and the valve stem are subjected to internal fluid pressure, the thin cylindrical sidewall of the valve stem expands outward to increase a sealing force between an outer diameter of the valve stem and the valve bore.

Continuous multi-fluid pump device, drive and actuating system and method

A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.

Modular pressure support system and method

A system and method of assembling a disposable fluid pump device is provided. The fluid pump device includes a pump body having a plurality of pump cylinders and at least one inlet selector valve for controlling fluid input to the pump cylinders. The method includes the steps of identifying at least one initial inlet selector valve position; generating, with at least one processor, encoded data representing at least the at least one inlet selector valve position; and setting the at least one selector valve to the at least one initial inlet selector valve position.

Assembly method for a fluid pump device for a continuous multi-fluid delivery system

The continuous fluid delivery systems includes a fluid pumping device comprising a pump housing comprising a base member with a plurality of inlet ports and at least one outlet port and at least two pairs of opposing pistons movably associated with the housing. Each pair of opposing pistons at least in part defines a respective pumping chamber of the fluid pumping device. The pistons in each pair of opposing pistons may be independently controlled such that any one of the plurality of inlet ports or the at least one outlet port is independently selectable to be in fluid communication with one of the respective pumping chambers. A drive system may be interfaced with the respective pistons to at least reciprocally operate the pistons relative to the base member. The pump housing and the at least two pairs of opposing pistons may comprise a disposable unit.

Modular pressure support system

An electrophotographic image forming apparatus comprises a drive roller having a textured finish with a plurality of microscopic protrusions and a plurality of microscopic depressions; the drive roller comprising a shaft and a surface coating on the shaft; a flexible belt having a first hardness driven by the drive roller, the belt moving at least one of a toner image or a recording media having a toner image thereon; with the surface coating comprising a base compound and plurality of grit particles having a second hardness which is higher than the first hardness. The grit coating may advantageously have a thickness of not more than about 50 microns. The grit particles may comprise one or more ceramics, or one or more polymer compounds, or other materials. The drive roller advantageously has a coefficient of static friction of at least 0.5 with the belt.
