A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

Pumping fluid delivery systems and methods using force application assembly

A system for priming an infusion pump is disclosed. The system includes a priming cap including a septum and configured to matably connect with a male part comprising a needle and attached to a length of tubing for fluid, wherein when matably connected with the male part, the priming cap occludes the tubing.

Infusion pump methods, systems and apparatus

A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

Patch-sized fluid delivery systems and methods

A flow control device is disclosed. The flow control device includes a solenoid, the solenoid including an armature. Also, a piston connected to the armature. The piston includes a primary orifice. The piston having an open position and a closed position. A piston spring connected to the piston is also includes and at least one secondary orifice. The movement of the piston to the open position at least partially opens the at least one secondary orifice and the movement of the piston to the closed position at least partially closes the at least one secondary orifice. The movement of the armature actuates the piston movement and controls fluid flow from the primary orifice through the at least one secondary orifice.

Product dispensing system

Slide clamp

A flow sensor includes a fluid chamber configured to receive a fluid. A diaphragm assembly is configured to be displaced whenever the fluid within the fluid chamber is displaced. A transducer assembly is configured to monitor the displacement of the diaphragm assembly and generate a signal based, at least in part, upon the quantity of fluid displaced within the fluid chamber.

A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

Adhesive and peripheral systems and methods for medical devices

A peristaltic pump having at least first, second, and third stages is provided. The peristaltic pump includes a plunger, inlet and outlet valves, a spring, and an actuator. The plunger actuates toward and away from a tube, the inlet valve is upstream of the plunger, the outlet valve is downstream of the plunger, the spring biases the plunger toward the tube, and the actuator mechanically engages and disengages from the plunger. In the first stage, the inlet valve is opened and the plunger is actuated from the tube, in the second stage, the inlet valve is closed, the plunger is actuated toward the tube, and the actuator is mechanically disengaged from the plunger, and in the third stage, the outlet valve is opened. In the third stage or in a fourth stage, the actuator actuates the plunger toward the tube to discharge fluid downstream past the outlet valve.

Peristaltic pump

A method for controlling a device using a shape-memory alloy wire is disclosed. The method includes determining an ontime for the shape-memory alloy wire based on a target volume to be pumped by a pump plunger, determining the temperature of the shape-memory alloy wire and adjusting the ontime based on the temperature of the shape-memory alloy wire.

Method and system for shape-memory alloy wire control

A protective mechanism for use when gripping a medical device to a rack is provided. A related system and method are also provided. The protective mechanism includes a connector, an actuation member configured to have a first end portion and a second end portion. The cover member is configured to interact with the actuation member so as to pivot to uncover the connector when the actuation member pivots in a first direction and to pivot to cover the connector when the actuation member pivots in a second direction.

System, method, and apparatus for clamping

A pump for treating a patient is disclosed that includes a spring-biased plunger biased toward actuation against a tube; a cam shaft configured to actuate the spring-based plunger; a lever actuatable between a closed position and an open position; a shaft coupled to the lever, the shaft having a central axis centrally along the length of the shaft, the shaft coupled to the lever to rotate around the central axis in accordance with actuation of the lever; and a lift cam pivotally coupled to the shaft, wherein the lift cam pivots around a lift cam axis, the lift cam axis of the lift cam is parallel to the central axis of the shaft, and the lift cam engages with the spring-based plunger to lift the spring-biased plunger off of the cam shaft as the shaft rotates in accordance with actuating the lever to the open position.

Medical pump

Handle of a central controller

A peristaltic pump includes a plunger-cam follower, a tube receiver, a spring-biased plunger, a spring, a position sensor, and a processor. The plunger-cam follower engages the plunger cam to follow the plunger cam and to disengage from the plunger cam. The spring-biased plunger is coupled to the plunger-cam follower and the spring biases the spring-biased plunger toward the tube receiver. The position sensor determines a position of the spring-biased plunger when the plunger-cam follower is disengaged from the plunger came. The processor estimates fluid flow utilizing at least the position of the spring-biased plunger as indicated by the position sensor when the plunger-cam follower is disengaged from the plunger cam and the spring biases the spring-biased plunger against the tube.
