A device and a system that delivers continuous positive airway pressure in conjunction with oxygen delivery is disclosed. The system is portable so that patients may be mobile and conveniently travel. Several means are disclosed for integrating oxygen production into a positive airway pressure (PAP) device, including oxygen production machinery entirely integrated into the PAP housing, oxygen production machinery that mates with a PAP device but which may operate independently, and where portions of the oxygen production machinery are located in the PAP housing and other portions (for example, the compressor) are located in a separate module, such as, for example, an AC-to-DC power conversion module.

A treatment device system includes a treatment machine for performing a therapy on a patient, the treatment machine including at least one fluid conveyor and a controller, the controller having a first memory, to cause the at least one fluid conveyor to produce a therapeutic fluid by mixing purified water and at least one concentrate. The system also includes and a water purifier in fluid communication with and providing the purified water to the treatment machine. A wired or wireless control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier, wherein the controller of the treatment machine transmits data via the control line to the internal central controller of the water purifier for control of the water purifier, the data provided based on at least one of the operator inputs received via the user interface.

A peritoneal dialysis device includes a disposable tubing set that includes a fill line with a patient access connector at one end and a dialysis fluid receiving end opposite the patient access connector end. The device also includes a fill-side pressure measuring sensor attached at the fill end and forming a disposable component of the tubing set and a patient-side pressure measuring sensor located at the fluid receiving end. The patient-side and fill-side pressure measuring sensors are adapted for measuring pressure in the fill line at the respective ends thereof. The device also includes a controller configured to regulate a rate of flow in the fill line responsively to a signal from the at least the patient-side pressure measuring sensor.

The invention provides a device for aspirating uterine fluid of a woman in her period, enabling her, without using tampons, pads or synthetic hormones, to be free of menstrual flow for six or more hours and to be involved in even the most demanding activities entirely undisturbed.

A drainage device for removing fluid from a body cavity of a patient is provided. The device comprises a drainage tube, and a pressure sensing means. The drainage tube is connectable to a pump unit, which unit is configured to apply a suction pressure to the fluid in the body cavity, and the pressure sensing means is configured to detect when the applied suction pressure is at or above a predetermined threshold level.

The invention relates to the field of inhalation devices for liquids. In particular, the invention relates to an inhalation device having improved flow characteristics. A inhalation device for medically active liquids (F) for generation of an aerosol comprises a housing (1), inside this housing (1) a reservoir (2) for storing a liquid (F), a pumping device with a hollow cylinder (9) providing a pumping chamber (3) for the generation of a pressure inside said pumping chamber (3), wherein the pumping chamber is fluidically connected with the reservoir (2) via an inlet check valve (4) which blocks in direction of the reservoir (2), a riser pipe (5) which can be received with at least one reservoir-facing, interior end (5A) in said hollow cylinder (9), and a nozzle (6) which is connected liquid-tight to an exterior end (5B) of the riser pipe (5), wherein the volume of the pumping chamber (3) is changeable by means of relative motion of the cylinder (9) to the riser pipe (5), and is characterised in that the riser pipe (5) is immobile and firmly attached to the housing (1) and to the nozzle (6), whereas the hollow cylinder (9) is moveable relative to the housing (1) and to the nozzle (6). The invention also discloses a method for the generation of an aerosol of a medically active liquid (F) by means of an inhalation device.

The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

A peritoneal dialysis (“PD”) system includes a housing; a PD fluid pump housed by the housing; a dual lumen patient line extending from the housing, the dual lumen patient line including a fill lumen and a return lumen; a PD fluid fill line in fluid communication with the fill lumen and an outlet of the PD fluid pump; a PD fluid return line in fluid communication with the return lumen and an inlet of the PD fluid pump; a fill pressure sensor configured to detect PD fluid pressure along the PD fluid fill line; a return pressure sensor configured to detect PD fluid pressure along the PD fluid return line; and a control unit configured to use outputs from the fill and return pressure sensors to determine if one of the fill lumen or the return lumen of the dual lumen patient line is occluded.

The present invention relates to an apparatus for performing peritoneal dialysis, the apparatus comprising means for delivering dialysis fluid to the peritoneal cavity of a patient, a measurement device for measuring the fluid pressure of the delivered dialysis fluid and/or the fluid pressure in the peritoneal cavity, i. e. the intraperitoneal pressure and/or any pressure related thereto, and a control unit operably connected to said means and the measurement device, wherein the control unit is configured to effect an inflow or outflow phase encompassing a series of fill-and-measurement or drain-and-measurement steps, each step comprising delivering a predetermined quantity of dialysis fluid to the peritoneal cavity or draining a predetermined quantity of dialysis fluid from the peritoneal cavity and subsequently measuring and recording a pressure value.

The disclosure relates to devices and methods for the treatment of edema, which devices use a restrictor for flow compensation. Devices and methods of the invention further use a flow-restrictor in the circulatory system, upstream of an intravascular pump, to balance pressure changes induced by the pump and to compensate for downstream flow. The device may be provided as an indwelling, intravascular catheter with a mechanical pump such as an impeller and a selectively deployable restrictor such as an inflatable balloon. Congestive heart failure or edema is treated by\operating the pump in an innominate vein and using the restrictor for flow compensation, to restrict the upstream flow and thus amplify or maintain pressure reduction at the lymphatic outlet.
