The device comprise a self-pressurized reservoir for storing the medication for subsequent delivery to a patient, a needle for delivering the medication to the patient subcutaneously, a first MEMS device configured as a microvalve in a fluid path between the self-pressurized reservoir and needle for controlling flowrate of medication through the needle as the self-pressurized reservoir discharges, a second MEMS device configured as a micropump configured to increase flowrate of the medication in the fluid path to ensure a constant flowrate in the fluid path as the self-pressurized discharges independent of orientation of the device, a flow sensor configured to measure flowrate in the fluid path for controlling microvalve and micropump, and control circuitry connected to the microvalve, micropump and flow sensor for controlling operation of the micropump and microvalve.

A coupler of a valve assembly for coupling a flow control valve to an infusion device. The coupler includes a proximal portion and a distal portion. The proximal portion comprises a plurality of recessed segments configured for receiving the infusion device. The distal portion comprises a valve flange that defines a central cavity for receiving the flow control valve. The valve flange comprises a swage extending radially inward to the central cavity for mechanically engaging a luer lock fitting of the valve assembly.

Disclosed is a tube connector for medical treatment including a housing including an internal channel configured to allow an inflow pipe disposed at the front end thereof and an outflow pipe disposed at the rear end thereof to fluidly communicate with each other, an insertion hole formed from the outer surface of the rear end of the housing to the internal channel, and at least one branch pipe disposed so as to fluidly communicate with the internal channel, a push button having a through hole, the push button being disposed in the insertion hole so as to be movable upwards and downwards, and an elastically deformable dome-shaped balloon configured to surround the insertion hole of the housing, the lower part of the balloon being open, wherein the internal channel of the housing is opened and closed through the upward and downward movement of the push button.

A wearable infusion port for infusing a fluid includes a first housing that defines an inlet port to receive the fluid, and a second housing coupled to the first housing. The second housing is to be coupled to an anatomy. The wearable infusion port includes a valve assembly fluidly coupled to the inlet port, and the valve assembly is movable from a closed state to an opened state to dispense the fluid. The wearable infusion port includes a cannula assembly extending through the first housing and the second housing, and the cannula assembly includes a cannula fluidly coupled to the valve assembly. The cannula is to be coupled to the anatomy. The wearable infusion port includes a flow sensor fluidly coupled to the inlet port and the cannula. The flow sensor is fluidly coupled upstream from the cannula to observe an amount of fluid received by the cannula.

A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, a first flexible tube having a first lumen, a second flexible tube having a second lumen, and a valve assembly configured to selectively and reversibly compress the first flexible tube and the second flexible tube to open and close the first lumen and the second lumen. The valve assembly includes a first anvil moveable between a retracted position in which the first lumen is at least partially pen and an extended position in which the first anvil closes the first lumen, a second anvil moveable between a retracted position in which the second lumen is at least partially open and an extended position in which the second anvil closes the second lumen, and at least one eccentric cam rotatable to move the first anvil and the second anvil between the retracted and extended positions.

A levered flow regulation clamp assembly for adjusting the fluid flow rate in a connector tube of an infusion set is provided. The levered flow regulation clamp assembly includes a housing to receive the connector tube and a slider rotatably engaged within the housing and configured to compress the connector tube to provide a fluid flow adjustment. Infusion sets and methods of adjusting fluid flow rates are also provided.

A system suitable for delivering a therapeutic agent to a target site may include a container for holding a therapeutic agent, a pressure source having pressurized fluid, where the pressure source is in selective fluid communication with at least a portion of the container, a catheter in selective fluid communication with the container and configured for delivery of the therapeutic agent to a target site, a first valve connected between the container and the catheter, a second valve connected between the pressure source and the container, a button configured to selectively actuate the second valve, and a brake assembly coupled to the first valve and configured to selectively permit actuation of the second valve, such that when the first valve is in a first state, the brake assembly blocks the button such that the button does not actuate the second valve.

An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.

An intravenous IV pressure assembly includes a body, an outlet port disposed on the body and a connector coupled to the outlet port, the connector being configured to couple with a fluid reservoir and the IV pressure assembly configured as a pressurized container. IV sets with an IV pressure assembly and methods of operating an IV pressure assembly are also provided.
