Automatic injection device

A dialysis system includes a disposable cassette including a flexible sheet and a plurality of dialysis fluid pathways, a plurality of actuators operable with the flexible sheet to direct dialysis fluid through the plurality of dialysis fluid pathways, and a controller configured to (i) determine at least one limitation of the plurality of dialysis fluid pathways, (ii) generate a flow schedule indicating how dialysis fluid should be directed through the plurality of dialysis fluid pathways in accordance with the at least one limitation, and (iii) control the plurality of actuators so that dialysis fluid is pumped through the plurality of dialysis fluid pathways according to the flow schedule.

Dialysis system and method for pumping and valving according to flow schedule

An embodiment of a peritoneal dialysis system includes an enclosure, a door hingedly attached to the enclosure, a stepper motor housed by the enclosure, a solid pump piston in operable communication with the stepper motor and including a solid pump shaft attached to or integrally formed with a solid pump head, and a disposable unit contacting the enclosure and the door. The disposable unit includes a moveable membrane operable with the solid pump head. The stepper motor is configured to move the solid pump head towards and away from the disposable unit. The system further includes a position detection apparatus operable with the stepper motor and located to provide an output indicative of a position of the solid pump head relative to a reference position.

Automated peritoneal dialysis system using stepper motor

Automatic injection device includes a housing, a syringe, a plunger, and a syringe carrier. The housing includes a barrel. The barrel includes an elongated window to allow viewing of contents inside the housing. The syringe is disposed within the housing and has a reservoir. The plunger is at least partially disposed within the syringe and includes a visual indicator. The syringe carrier is disposed within the housing and configured to contain the syringe and displace the syringe within the housing between a first position and a second position. The syringe carrier can have at least one opening and at least one pair of legs defining at least a portion of the at least one opening.

Exemplary embodiments provide automatic injection devices in which a shroud is automatically deployed to protectively sheath a needle after an injection is performed. Exemplary embodiments also provide shroud deployment assemblies including a shroud and a syringe carrier that, when cooperatively configured in an automatic injection device, ensure that the shroud is automatically and completely deployed after an injection is performed using the automatic injection device. Exemplary embodiments are also configured to ensure that, once the shroud is deployed to an extended position to sheath the needle, accidental forces applied to the shroud do not succeed in subsequently retracting the shroud to a retracted position in which the needle would become exposed.

Automatic injection device includes a housing, a syringe, a plunger, and a syringe carrier. The housing includes a barrel between a first end and a second end. The barrel includes an elongated window to allow viewing of contents inside the housing. The syringe is disposed within the housing and has a reservoir. The plunger is at least partially disposed within the syringe and includes a visual indicator. The syringe carrier is disposed within the housing and configured to contain the syringe and displace the syringe within the housing between a first position and a second position. The syringe carrier can be substantially transparent. The syringe carrier can have first and second legs and an extension disposed therebetween, and at least a portion of the extension can be configured to align with the window and the reservoir when the syringe carrier is in the first position.

Exemplary embodiments provide a syringe plunger formed of a polymeric material. The syringe plunger includes a pressurizer disposed at a proximal end, and a distal end bifurcated into a first plunger arm having a first conical surface and a second conical surface, and a second plunger arm having a first conical surface and a second conical surface. The distal end includes a first contact surface defined by the first conical surface of the first plunger arm and the first conical surface of the second plunger arm, the first contact surface configured to initially contact a firing engagement mechanism, the first contact surface disposed at a first angle of between about 40&#xb0; and about 80&#xb0; relative to a longitudinal axis of the syringe plunger. The distal end also includes a second contact surface defined by the second conical surface of the first plunger arm and the second conical surface of the second plunger arm, the second contact surface configured to contact the firing engagement mechanism subsequent to contact by the first contact surface.
