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.

Methods of bioprinting a bio-ink construct on an internal tissue defect or a chondral defect during a minimally invasive surgery on an individual in need thereof are provided, comprising: visualizing the defect; positioning a bioprinter comprising a printhead within proximity of or in contact with the defect; and ejecting a bio-ink from the printhead onto the defect to form a bio-ink layer, thereby generating a bio-ink construct. Further provided are systems for bioprinting a bio-ink construct on an internal tissue defect during a minimally invasive surgery on an individual in need thereof, comprising a control system, an endoscope, and a bioprinter comprising a printhead.

Disclosed is an intravenous drug dispensing kit including: a cylinder cartridge for introducing and discharging external fluids through changes in the volume of a cylinder occurring when a pair of first and second pistons disposed therein is fixed and rotates relatively to each other; a first tube connected to an outlet tube of the cylinder cartridge; a three-way valve having a first introducing flow path, a second introducing flow path, and a discharge flow path connected to any one of the first introducing flow path and the second introducing flow path; a second tube for connecting the discharge flow path of the three-way valve to an inlet tube of the cylinder cartridge; a third tube connected to the first introducing flow path of the three-way valve; and a fourth tube connected to the second introducing flow path of the three-way valve.

A rotary pump is presented for use in a medicament delivery device, where the pump has a back plate having an inner surface and a rotor housing is positioned adjacent to the back plate having a peripheral wall. A front plate support is connected to the back plate and a flexible front plate is positioned between the front plate support and the rotor housing. The pump is rotated using a planetary gear transmission, where an eccentric shaft is operatively connected to the planetary gear mechanism. A rotor is rotationally fixed to the eccentric shaft and movably positioned within the rotor housing. The rotor has three lobes, where each lobe has two peripheral curved surfaces sharing a common apex, where a first portion of each peripheral surface adjacent to the apex defines a non-smooth curve.

A dermal patch system for administering a pharmaceutical includes a vial that stores a pharmaceutical and a cartridge coupled to the vial. The cartridge includes a pull mechanism, a pump, a plurality of microneedles in communication with the vial. The microneedles are configured to move between an undeployed position to a deployed position. When pulled, the pull mechanism is configured to cause the microneedles to move from the undeployed position to the deployed position and cause the pump to pump the pharmaceutical from the vial and to the microneedles.

The present disclosure relates to a medical pump for dispensing a liquid. The medical pump includes a housing, a receptacle and a piston. The housing includes an inlet for receiving said liquid and an outlet for dispensing said liquid. The receptacle includes a chamber and a passage that is in fluid communication with the chamber. The receptacle is received in the housing and is axially movable relative to the housing from a filling position, wherein the passage fluidly communicates the chamber with the inlet, to a dispensing position, wherein the passage fluidly communicates the chamber with the outlet. The piston is received in the chamber and is configured such that when the receptacle is in the filling position the piston is axially moveable relative to the receptacle and when the receptacle is in the dispensing position the piston is axially moveable relative to the receptacle.

A fluid infusion device includes a housing having a reservoir chamber that receives a fluid reservoir. The fluid reservoir has a first end and a second end. The fluid infusion device includes a connector system having a first body section coupled to a second body section. The first body section defines a bore in communication with a chamber and a counterbore of the second body section to define a fluid flow path. The chamber of the second body section is in fluid communication with a vent subsystem defined through the second body section. The vent subsystem terminates in an outlet, and the vent subsystem is to direct gas in the fluid flow path through the second body section to the outlet. The fluid infusion device includes at least one ring disposed within the reservoir chamber that cooperates with the connector system to securely couple the connector system to the housing.

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.

In some embodiments, a self-monitoring intravenous catheter system is provided. An alarm controller is provided that receives signals representing a pH value, an oxygen saturation value, and a pressure value in proximity to the distal end of the catheter. By performing a fuzzy logic analysis of the values, the alarm controller is able to detect that the catheter is about to fail or has failed, and can cause alerts to be presented. In some embodiments, an intravenous catheter is provided that has a pH sensor and an oximeter disposed at a distal end of the catheter to obtain the pH value and oxygen saturation values analyzed by the alarm controller. Embodiments of the catheter and self-monitoring intravenous catheter system may be particularly useful in treating neonates, who are sensitive to catheter failure and are not capable of detecting the signs of failure themselves.

A fluid injector system includes a powered fluid injector, a connection port configured to receive a single-use disposable set having tubing connected to a fluid inlet port at a first end and connected to a waste outlet port at a second end, and a detector associated with the connection port and configured to generate a signal in response to a sonic, infrasonic, or ultrasonic wave emitted from the single-use disposable set during a priming operation of the single-use disposable set. In some examples, the detector is configured to generate a signal if the frequency of the wave emitted from the single-use disposable set is outside a predetermined range of frequencies corresponding to a predetermined range of frequencies of air expelled from the tubing. A method for detecting the multiple uses of a single-use disposable set connected to a fluid injector system is also provided.
