Embodiments of the present invention are directed to a liquid delivery apparatus. A non-limiting example of the apparatus includes a substrate including a cavity formed in a surface of the substrate. The apparatus can also include a membrane disposed on the surface of the substrate covering an opening of the cavity. The apparatus can also include a hydrophobic layer disposed on the membrane. The apparatus can also include a seal disposed between the membrane and the substrate, wherein the seal surrounds the opening of the cavity. The apparatus can also include an electrode layer coupled to the membrane.

An atomizer device comprises a container (20) with a liquid chamber (21) for receiving a liquid for atomizing and a spray nozzle (50) which is able and configured to form a mist from the liquid under an increased operating pressure. The liquid chamber (21) is closed by a plunger (22) which is received movably therein and is able and configured to expel during an axial displacement at least a part of the liquid from the liquid chamber. Provided between the plunger (22) and the spray nozzle (50) is an air bubble barrier (80) which is at least substantially unbridgeable to possible air bubbles in the liquid, but which comprises a passage (85) for the purpose of allowing at least substantially free passage of the liquid. In a method for preparing such a container it is subjected to a centrifuging step in order to expel possibly enclosed air upstream of the barrier device as far as possible.

Modular intravenous (IV) assemblies are provided. The modular IV assembly includes a drip chamber having a body and an inlet connector, a base housing coupled directly to a base portion of the drip chamber, the base housing having an inlet port in fluid connection with the drip chamber and a flow path cavity in fluid connection with the inlet port and a flow control assembly coupled directly to a first portion of the base housing. Any of a filter assembly, an anti-run dry member, a check valve and an air vent assembly may be included in the modular IV assembly. IV sets and methods of use are also provided.

The invention relates to the providing of hydrophobic and hydrophilic polymer-based hollow fiber membranes containing a water-insoluble antioxidant; in particular, the invention relates to the providing of hollow fiber membranes for the extracorporeal treatment of blood, wherein the hollow fiber membranes have improved biocompatibility relative to treatment blood, in particular improved complement activation and lower platelet loss vis-à-vis treatment blood. At the same time, the elution of hydrophilic polymers from the lumen of the hollow fiber membrane is reduced.

A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side of the plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

Disclosed embodiments relate to wound therapy apparatuses and methods for use in negative pressure wound therapy (NPWT). Such wound therapy apparatuses and methods may reduce maceration during NPWT. The wound therapy apparatus may include a porous hydrophobic layer surrounded by a hydrophilic ring. The hydrophilic ring may serve to prevent passage of liquid while negative pressure is applied to the wound, but allow liquid passage to an absorbent ring when negative pressure is no longer applied. A transmission layer may also be included, underlying the absorbent layer.

A disposable transfer device has an injection device support surface for receiving an on-body injection device thereon and a flow path arrangement for transfer of fluid into the injection device, the transfer device being configured to define preferential gripping areas for user gripping of an injection device when such device is located on the support surface and interfering areas for interfering with user gripping of the injection device in the interfering areas.

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.

An inductive inline dialysis fluid heater is disclosed. In an example, a dialysis fluid heater includes a cylindrical tube including an inner diameter that is between 4.00 millimeters (“mm”) and 12.7 mm. The dialysis fluid heater also includes a susceptor located within the cylindrical tube and an inductive coil extending around the cylindrical tube in a non-contacting arrangement. The dialysis fluid heater further includes power electronics in electrical communication with the inductive coil and configured to supply an electrical current to the inductive coil, causing the susceptor to heat.
