A mobile infusion pump is used for the constant delivery of a fluid medium. The infusion pump comprises a balloon body for receiving the medium as well as a filling unit and a delivery unit that are in a fluid connection with the balloon body for filling the medium into the balloon body and delivering the medium from the balloon body to a patient. A throttling unit defines a delivery flow rate of the medium. By means of a plurality of continuous longitudinal ribs arranged on a part of the balloon body configured as a tube body, the expansion behavior of the balloon body is improved.

A fill adapter for filling a reservoir and a related method are disclosed herein. The fill adapter includes a button assembly actuator and a pump chamber plunger actuator hingeably attached to the button assembly actuator, wherein the actuation of the button assembly actuator actuates the pump chamber plunger actuator and wherein the pump chamber plunger actuator actuates a pump chamber membrane before the at least one button assembly is actuated.

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.

A drug delivery system includes a delivery container including a container body adapted to accommodate a drug therein, a supply line, a flow rate sensor, and a flow controller. The delivery container further includes an outlet port and is constructed from a resilient material. The container body is adapted to exert an urging force on the drug to expel the drug from the outlet port. The supply line is operably coupled to the outlet port to deliver the drug to a user. The flow sensor senses a flow rate of the drug within the supply line. The flow controller is configured to regulate a flow rate of the drug; the flow controller includes a supply line restrictor and a controller for adjusting the supply line restrictor between at least two settings.

An infusion system includes a chamber for accommodating an infusion fluid and an infusion line for transferring the infusion fluid from the chamber. The infusion line includes at least a rotor module or is connected to a rotor module at least at a downstream end of the infusion line. The rotor module includes a rotor that is drivable by the infusion fluid.

The infusion pump for stem cells includes a liquor storage device and an infusion pipe. The inner wall of the liquor storage sac of the liquor storage device and inner walls of the infusion pipe are provided with an anionic protective film to prevent stem cells from adhering to the infusion pump by mutual repulsion between anions. The infusion method includes checking an infusion pump for integrity, losing a liquor stop clamp, injecting a mixed liquor of stem cells and medicine, covering a protective cap, opening the liquor stop clamp, closing the liquor stop clamp for use, connecting an external cone joint with a venous cannula, and then opening the liquor stop clamp. The method also includes steadily placing the liquor storage sac on a horizontal plane using an auxiliary placing device, and after infusion ends, closing the liquor stop clamp, and disconnecting the external cone joint.

A balloon type liquid medicine injector for continuously injecting a small amount of liquid medicine into a body of a patient is disclosed as to be easily assembled and to prevent unnecessary dead space while being inflated after a liquid medicine is injected, so as to be miniaturized. When a tube body is provided outside a fixed pipe, both ends of the tube body are folded and inserted into both ends of the fixed tube, to remove the dead space while being inserted inside the case. In addition, in a state where the both ends of the tube body are folded and inserted into the both ends of the fixed tube, an injection mechanism for injecting the liquid medicine or a stopper mechanism are coupled while pressing the tube body folded inward, so that a separate packing is unnecessary and the airtightness is maintained.
