Aspects of the present technology comprise a positioning and stabilising structure to hold a seal-forming structure in a therapeutically effective position on a head of a patient. The seal-forming structure may be constructed and arranged to form a seal with a region of the patients face surrounding an entrance to the patients airways for sealed delivery of a flow of air at a therapeutic pressure of at least 4 cmH2O with respect to ambient air pressure throughout the patients respiratory cycle in use. The positioning and stabilising structure may comprise a front hoop arranged to contact, in use, at least a region of the patients head superior to an otobasion superior of the patients head and a rear strap. The positioning and stabilising structure may comprise an adjustment mechanism for adjustment of the front hoop and the rear strap relative to the patients head, the adjustment mechanism being arranged in a single operation to adjust both the front hoop and rear strap to enable the positioning and stabilising structure to fit different size heads.

A breathing assistance apparatus has a pressurised gases source featuring a lightweight impeller with a plastic shaft. The impeller is shroudless. The plastic shaft is supported within the stator by a bearing structure. The resilient motor mount couples the stator and the housing and provides compliance and/or damping for the motor.

A medical device (100) for securing a catheter (700) to a support (600) is described, comprising a base element (200) having a first side (201) fixable to the support (600), and a second side (202) opposite the first side (201), and comprising a top element (500) having a first side (501) connectable with the second side (202) of the base element (200). When the first side (501) of the top element (500) is connected with the second side (202) of the base element (200), the top element (500) and the base element (200) are arranged for forming a feedthrough for the catheter (700) between the second side (202) of the base element (200) and the first side (501) of the top element (500). At least one of the base element (200) and the top element (500) comprises a deformable fluidum filled chamber (430), the deformable fluidum filled chamber (430) arranged such that the catheter (700) is locally tightly held between the base element (200) and the top element (500) when positioned there between.

Disclosed herein are vascular access systems and methods thereof. For example, a vascular access system includes a port configured for subdermal implantation and a single-use access device. The port can include a port hub and a catheter tube. The port hub can include an access funnel and a septum defining a pair of port-hub lumens. The catheter tube can include a septum defining a pair of catheter-tube lumens fluidly coupled to the pair of port-hub lumens. The access device can include a bifurcated hub and a pair of cannulas. The pair of cannulas defines a pair of cannula lumens coupled to a pair of access device-hub lumens of the bifurcated hub. The pair of cannulas can be configured to simultaneously insert into the access funnel and couple the pair of cannula lumens to the pair of catheter-tube lumens when the pair of cannulas is fully seated in the port hub.

A nebuliser for nebulising liquid droplets, including: a housing; at least one piezoelectric substrate (2) accommodated within the housing and having a transducer surface (2a) upon which is located at least one electroacoustic transducer (48) for generating acoustic wave energy within the at least one piezoelectric substrate (2), and an opposing non-transducer surface (2b); a liquid supply system for supplying a liquid to at least one of the transducer and non-transducer surfaces, the liquid supply system including a reservoir (3) for accommodating the liquid, and at least one relatively rigid supply conduit in contact with the at least one piezoelectric substrate (2) for supplying the liquid from the reservoir (3) to the at least one piezoelectric substrate (2); and a sensor for detecting a volume of liquid on the at least one piezoelectric substrate (2).

A patient interface a positioning and stabilising structure, which includes a gas delivery tube with a tube wall that has an interior passage for flow of pressurized air. A portion of the tube wall includes a patient contacting portion and a non-patient contacting portion. The patient contacting portion includes a layer of textile material or foam material configured to lie against the patient's head. At least a section of the non-patient contacting portion includes of a transparent and/or translucent material. The layer of textile material or foam material is bonded to the transparent and/or translucent material so that the tube wall is formed as a one piece construction. A plane extends generally transverse to longitudinal axis contains both (1) the textile material or foam material and (2) the transparent and/or translucent material, so that the patient may view the interior passage along a transverse axis extending through the plane.

A drug delivery device comprising a pumping system (4) and a liquid reservoir (7) fluidly connected to a delivery system outlet (12), the liquid reservoir comprising an elastic plunger (14) sealingly slidable within a container wall (13) of the liquid reservoir for expelling liquid out of the reservoir. The pumping system comprises a piston pump (5) comprising a plunger actuator arranged to displace the plunger (14), and a dosing unit (6) arranged downstream of the liquid reservoir (7) and fluidly connected to the liquid reservoir. The dosing unit (6) comprises a chamber portion (22) arranged between an inlet valve (24) and an outlet valve (26), the chamber portion (22) arranged to receive from the liquid reservoir a pump cycle volume of liquid under an operational pressure greater than ambient pressure generated by the piston pump, and to the deliver said pump cycle volume of liquid to the delivery system outlet, said pump cycle volume being dependent on the operational pressure.

The invention relates generally to wearable accessory carriers for mechanical circulatory support systems, and more specifically relates to belts for carrying peripheral components of a VAD. Such wearable accessory carriers may be suitable for carrying and retaining peripheral components of the VAD in a safe, comfortable, and convenient manner. In certain aspects, the invention provides a wearable accessory carrier configured as an elastic belt with several pockets for holding peripheral components. In other aspects, a wearable accessory carrier may be configured as a belt with a magnetic strip configured to carry one or more modular compartments or pockets for holding peripheral components via magnetic attachment. The wearable accessory carriers disclosed herein may be sized to fit around or configured to be worn on a patient's waist, lower or upper torso, thigh, calf, arm, or other limb.
