A wearable infusion pump assembly includes a reservoir for receiving an infusible fluid, and an external infusion set configured to deliver the infusible fluid to a user. A fluid delivery system is configured to deliver the infusible fluid from the reservoir to the external infusion set. The fluid delivery system includes a volume sensor assembly, and a pump assembly for extracting a quantity of infusible fluid from the reservoir and providing the quantity of infusible fluid to the volume sensor assembly. The volume sensor assembly is configured to determine the volume of at least a portion of the quantity of fluid. The fluid delivery system further includes a first valve assembly configured to selectively isolate the pump assembly from the reservoir, and a second valve assembly configured to selectively isolate the volume sensor assembly from the external infusion set.

Infusion pump assembly

An apparatus, system and method for regulating fluid flow are disclosed. An apparatus for infusing fluid into a patient includes a housing, a tube-contact member, a rotating arm, and a tube-retention cover. The housing has an opening on a front side of the housing. The opening is sized to receive a drip chamber having an inlet tube and an outlet tube. The tube-contact member contacts one of the inlet tube and the output tube of the drip chamber when inserted into the opening. The rotating arm is coupled to the tube-contact member and is configured to rotate along an axis. The tube-retention cover is configured to close when the drip chamber is initially loaded into the opening.

Apparatus for monitoring, regulating, or controlling fluid flow

A peristaltic pump disclosed herein includes a raceway, a plunger, a motor, and a heater. The raceway is configured to retain a tube (e.g., an IV tube). The plunger acts on the tube disposed within the raceway. The motor engages the plunger to actuate the plunger. The heater is disposed in thermal-conductive contact with the tube. That is, the heater, either through direct or indirect application, heats the tube.

Apparatus and method for infusing fluid through a tube by appropriately heating the tube

A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.

Apparatus for infusing fluid

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

Embodiments of the present invention relate generally to certain types of reciprocating positive-displacement pumps (which may be referred to hereinafter as 'pods,' “pump pods,” or “pod pumps”) used to pump fluids, such as a biological fluid (e.g., blood or peritoneal fluid), a therapeutic fluid (e.g., a medication solution), or a surfactant fluid. The pumps may be configured specifically to impart low shear forces and low turbulence on the fluid as the fluid is pumped from an inlet to an outlet. Such pumps may be particularly useful in pumping fluids that may be damaged by such shear forces (e.g., blood, and particularly heated blood, which is prone to hemolysis) or turbulence (e.g., surfactants or other fluids that may foam or otherwise be damaged or become unstable in the presence of turbulence).

Fluid pumping systems, devices and methods

A system for at least partial closed-loop control of a medical condition is disclosed. The system includes at least one medical fluid pump. The medical fluid pump including a sensor for determining the volume of fluid pumped by the pump. Also, at least one continuous analyte monitor, and a controller. The controller is in communication with the medical fluid pump and the at least one continuous analyte monitor. The controller includes a processor. The processor includes instructions for delivery of medical fluid based at least on data received from the at least one continuous analyte monitor.

Systems and methods for fluid delivery

A pump for administering an agent to a patient includes a housing, a motor, a gearbox, a sensor, and a controller. The motor may be coupled to housing. The gearbox is operatively connected to the motor. The sensor senses a rotation of the motor. The controller acts to control operation of the motor and monitor the quantity of the agent delivered to the patient. The pump also includes a pump assembly such that the pump is configured such that the pump assembly may be interchangeable from a syringe pump assembly and a peristaltic pump assembly.

Syringe pump

A wearable infusion pump assembly includes a reusable housing assembly, and a disposable housing assembly including a reservoir for receiving an infusible fluid. A releasable engagement assembly is configured to allow the reusable housing assembly to releasably engage the disposable housing assembly. A detachable external infusion set is configured to deliver the infusible fluid to a user.

Wearable pump assembly

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 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.
