The invention is directed to an inhaler device for inhalable liquids, in particular for the administration of inhalable volatile liquids such as halogenated volatile liquids, to a patient. According to particular embodiments, the inhaler device may include a liquid container for hermetically storing inhalable liquid; a wicking material for supporting inhalable liquid; a piercing member configured to pierce the liquid container, wherein the liquid container may be provided in a first position in which the piercing member does not engage the liquid container and inhalable liquid remains hermetically stored within the liquid container, and the liquid container may be displaced from the first position to a second position such that the piercing member pierces the liquid container to release inhalable liquid onto the wicking material, whereby during inhalation inhalable liquid vapor from the wicking material is delivered to the patient.

An aerosol provision system having a heating system; a power system for providing power to the heating system; and control circuitry for controlling a heating profile provided by the heating system, the control circuitry including a first sensor for measuring an output of the power system; and a second sensor for measuring an electrical property of the heating system, wherein the control circuitry controls the heating profile provided by the heating system based on measurements from the first sensor and the second sensor, and wherein the first sensor and second sensor are arranged to take measurements during periods of non-smoking.

A device for conditioning blood including a heat exchanger module including a heat exchanger fiber layer including heat exchanger fibers to receive a heat exchanger fluid and exchange heat with the blood, a gaseous micro-emboli removal module including a micro-porous fiber layer including micro-porous fibers to receive atmospheric or sub-atmospheric pressures such that at least some gaseous micro-emboli are drawn from the blood through the micro-porous fibers, a gas exchanger module including a gas exchanger fiber layer including gas exchanger fibers to receive a gas mixture and exchange gas with the blood, and a potting material body that embeds the heat exchanger fibers, the micro-porous fibers, and the gas exchanger fibers and defines a blood compartment that extends through the heat exchanger module, the gaseous micro-emboli removal module, and the gas exchanger module.

A patient interface may include a dual chamber cushion assembly having a nasal chamber and an oral chamber. The nasal chamber may be arranged to deliver pressurized breathable gas to a patients nasal passages, and the oral chamber may be arranged to deliver pressurized breathable gas to the patients oral passages. The nasal chamber may be pressurized to a different level than an oral chamber to promote nasal breathing. An air passage may fluidly connect the nasal chamber and the oral chamber so that pressurized breathable gas may flow from the nasal chamber to the oral chamber.

A pressure measurement pod for use in blood circuits includes a pressure sensing pod defining a chamber and having a rigid wall portion and an integral flexible wall portion forming a flexible, moveable, fluid-impermeable diaphragm with a first major side thereof facing an interior of the chamber and a second major side opposite the first major side. The second major side faces outwardly away from the chamber, and the pod has ports on sides of the chamber. The internal surfaces of the chamber and ports are shaped such that any contour following the internal surfaces to the outside of one of the ports traces only surfaces characterized by positive or neutral draft angles such that invasive mold portions may be withdrawn through the ports thereby permitting the pressure measurement pod to be molded in a single shot molding process.

The invention provides an insufflation apparatus having a housing and a gas generator arranged to be, at least partially, mounted to the housing. The housing includes a gas outlet for delivering gas to a patient and a gas storage chamber arranged to store gas and deliver it to the gas outlet. The gas generator includes a cartridge mount on the housing adapted to receive a gas generating cartridge, the gas generating cartridge containing gas generating material that generates gas that is delivered to the gas storage chamber. The invention also provides alternative insufflation apparatus, a gas cartridge and a method of generating insufflation gas.

Systems and methods for filtering materials from biologic fluids are discussed. Embodiments may be used to filter cerebrospinal fluid (CSF) from a human or animal subject. In an example, CSF is separated into a permeate and retentate using a tangential flow filter. The retentate is filtered again and then returned to the subject with the permeate. During operation of the system, various parameters may be modified, such as flow rate and waste rate.

The invention relates to an extracorporeal blood treatment device comprising a hydraulic system II comprising a plurality of flow paths, the blood treatment device having a control unit 40 which provides an operating mode for disinfecting the hydraulic system with a liquid which can be supplied via one of the flow paths. Moreover, the invention relates to a method for operating an extracorporeal blood treatment device with a hydraulic system comprising a plurality of flow paths. The blood treatment device according to the invention is characterized in that the hydraulic system II has a valve device 23 which provides several switching positions. The valve device 23 has an inlet 25A for the liquid for disinfecting the hydraulic system and a plurality of outlets 26A, 27A, 28A, wherein in a switching position the inlet 25A is connected to one of the outlets 26A, 27A, 28A and in another switching position the inlet is connected to a plurality of outlets 26A, 27A, 28A. The inlet 25A of the valve device 23 is in fluid communication with the flow path via which liquid for disinfecting the hydraulic system II can be supplied, and the outlets 26A, 27A, 28A of the valve device 23 are in fluid communication with another flow path of the hydraulic system, so that liquid can simultaneously be supplied to the individual flow paths.

A method of peritoneal removal of electrolytes and inflammatory mediators. The method begins with infusing a treatment solution into the peritoneal cavity of a patient by way of a catheter. The treatment solution is drained from the peritoneal cavity by way of the catheter. During the draining, the treatment solution is filtered for removing electrolytes and inflammatory mediators.

A stool management system having a tubular body including a first end section disposable in a rectum of a patient and a second end section including a first connector which detachably mates with a second connector coupled to a collection container which receives waste matter passed through the tubular body from the bowel of the patient.
