A breast pump device (1) comprises an expression kit (2), a vacuum unit (3), and a conduit (5) for establishing an air path between an air outlet (27) of the expression kit (2) and an air inlet (35) of the vacuum unit (3). The expression kit (2) is equipped with a barrier portion (26) for preventing milk leakage from the expression kit (2) towards the hose (5) and the vacuum unit (3). In case some droplets of milk enter the barrier portion (26) and/or drawn through the barrier portion (26) by an ongoing pumping action, aspects of the behavior of the motor (32) for driving the pump (31) are influenced, and the insight that this happens is used for terminating operation of the motor (32) as soon as a too large deviation of one or more operational characteristics of the motor (32) with respect to a reference is found.

Systems and methods are provided for generating and applying biomimicry tear film layers to a cornea surface. An example method includes forming a multiple layered tear film that are optically transparent, ultra-thin, and smoothly conforming to cornea surface. The multiple layered tear film can include a biomimicry adhesive layer, a biomimicry aqueous layer, and a biomimicry lipid layer. An atomizer/nebulizer/micronizer can be used to generate and applying the biomimicry tear film layers.

Described herein are methods which involve minimizing or eliminating the occurrence of delayed negative effects that may arise from exposure to reduced oxygen partial pressure. An amount of supplemental oxygen, which substantially mimics a target oxygen partial pressure, is administered to an individual that is exposed to a reduced oxygen partial pressure environment, to compensate for the reduced oxygen partial pressure. The target partial pressure may be selected such that the individual experiences substantially no change in the oxygen partial pressure. Individuals receiving the supplemental oxygen may be healthy, have special sensitivities, or have a pre-existing neurological condition.

The invention provides an inhalation device system for the in-halative administration of a medically active liquid in nebulized form, the system comprising an inhalation device and an exchangeable reservoir for holding the medically active liquid, wherein the inhalation device comprises - a housing having a receiving unit, the receiving unit having a connection unit adapted to releasably and fluidically connect to a connection port of the exchangeable reservoir, the receiving unit being adapted to receive and fluidically connect to the exchangeable reservoir; - a nozzle for nebulization of the medically active liquid; and - a pumping unit arranged within the housing and adapted to be fluidically connected to the reservoir (via the connection unit of the receiving unit) and to the nozzle and being adapted to convey (pressurize, pump) the medically active liquid in a downstream direction from the reservoir to the nozzle.

A system and method for dermal spraying includes a portable, hand-held dermal application device with one or more disposable cartridges that spray a dermal formulation onto the skin, the disposable cartridge having a nozzle that can be activated by placing the cartridge into the spray device.

Vaporizer and/or electronic cigarette chargers useful for the recharging of rechargeable vaporizer or electronic cigarette power supplies such as batteries, compatible vaporizers and/or electronic cigarettes, their components, charging contacts, methods of their use and kits containing such chargers are disclosed.

A peritoneal dialysis system includes a control unit configured to cause (i) a fluid inlet valve and a fluid outlet valve to occlude a fluid inlet line and a fluid outlet line, respectively, while a linear actuator moves a piston to create a positive pressure within a pump housing, the positive pressure measured by a pressure sensor, and (ii) the fluid inlet valve to occlude the fluid inlet line and the fluid outlet valve to open the fluid outlet line, while the linear actuator moves the piston so as to maintain the positive pressure within the pump housing while fluid is pumped out of the fluid pump chamber via the opened fluid outlet line.

In one aspect, a peritoneal dialysis (PD) system includes a housing that receives a disposable cassette, a plurality of pinch valves that receive respective sections of fluid tubing of the disposable cassette, an air port that forms an airtight seal with an air line of the disposable cassette, an air pump that alternatingly pushes air out of the air port and pulls air in from the air port, and a computer processor that controls the plurality of pinch valves and the air pump such that the cassette performs a dwell phase in which the diaphragm pump pumps fresh dialysate from a dialysate bag to a heater bag, a fill phase in which the diaphragm pump pumps the fresh dialysate from the heater bag to a patient line, and a drain phase in which the diaphragm pump pumps spent dialysate form the patient to a drain.

Extracorporeal blood treatment systems and methods to detect the connection of one or more components (e.g., of an extracorporeal blood set) thereto (e.g., to one or more pressure transducers contained in the system housing) by, for example, controlling an air pump apparatus to provide air to a connection port at which the component is to be connected and monitoring pressure resulting therefrom to detect whether the component is operatively connected (e.g., based on a detected change in the monitored pressure due to the increased resistance, based on a monitored rate of decay of pressure of injected air, etc.).
