An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

A system and method removing air from a reservoir, the system comprising the reservoir that carries a medicament, a first pump connected to the reservoir that draws the medicament out of the reservoir, an air removal device connected to the first pump that releases air from the medicament, and a second pump connected to the air removal device that delivers the medicament.

An inline microgravity air trap device includes an elongate air trap chamber, the air trap chamber having a blind end, an opposite air outlet end containing a gas egress opening, a fluid inlet port connecting to a pressurized fluid supply, a fluid outlet port connecting the air trap chamber to a fluid delivery destination, a filter forming a tube having an interior, a first end at the blind end of the air trap chamber and a second end at the gas egress opening, and a structural insert in the interior of the tube, having a first insert end located at the blind end, and a second insert end located the air outlet end, where the chamber is formed to direct fluid from the pressurized fluid supply to accelerate centrifugally around the filter, forcing gas contained in the fluid to pass through the filter into the interior of the tube.

The invention disclosed herein generally relates to matrices comprising polymers and methods for preparing them.

A syringe system includes a syringe and a filtration device connected to the syringe for sterilizing and introducing fluid into the syringe. The syringe includes a syringe barrel having a proximal end defining a barrel opening, a distal end defining a delivery opening, a bore extending between the proximal end and the distal end, and a stopper disposed in the bore of the syringe barrel. The filtration device has an inlet and an outlet coupled in fluid communication with the delivery opening at the distal end of the syringe barrel. The filtration device includes a stem and a filter membrane disposed in line with the stem. The filter membrane optionally has a plurality of pores each with a nominal pore size in a range of approximately 0.1 m to approximately 0.5 m such that a pharmaceutical fluid can be introduced as a sterilized pharmaceutical fluid into the bore of the syringe barrel by passing through the filtration device.

A device for administering an infusion or transfusion of liquid from a container includes a pump for pumping liquid to a patient connection via a conduit having a liquid-retaining filter membrane. The device also includes a pressure measuring device for acquiring measurement values corresponding to a pump-inlet-side pressure, and a control device for detecting a change in the pump-inlet-side pressure based on the measurement values. The control device determines, based on the change in the pump-inlet-side pressure, whether to stop pumping. The control device also generates a control signal when the pumping is to be stopped. Moreover, the control device emits, based on the control signal, a communication signal to a data connection between the device and a unit that reads the communication signal. In addition, or in the alternative, the control device switches the device from a first state to a second state based on the control signal.

An infusion line gas removal device and process for its fabrication and use is disclosed herein. The gas removal device includes a gas permeable tubing coupled between first and second couplers, and an impermeable tubing shield encasing the gas permeable tubing between the first and second couplers. The impermeable tubing shield is larger in diameter than the gas permeable tubing and comprises at least one vent and a plurality of supports, the plurality of supports being between the tubing shield and the gas permeable tubing and configured to support the gas permeable tubing within the impermeable tubing shield in a fixed position between the first and second couplers and facilitate passage of gas from the gas permeable tubing to the at least one vent.

Provided herein are systems and methods for monitoring one or more health or physiological parameters in a subject. The systems and methods may comprise a patch coupled to an injector. Data may be transmitted to a mobile device or remote server, where the data may be processed. Processed data may be used to inform a subject on a health or physiological condition.

Filter for infusion medical lines having a box-like body within which there are arranged four filtering hydrophilic membranes parallel and spaced from each other so as to form three interspaces placed in communication with the inlet connector of the liquid to be filtered.
