A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing has also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

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.

An oxygen pressure regulating device (100) is disclosed. The device (100) comprises a housing (102) including an inlet port (104) and an outlet port (106), the housing (102) including: a spring unit (112) including a plate (116) placed in fluid communication with the inlet port (104), the plate (116) being configured to be moved when impinged upon by an oxygen stream at a first pressure received through the inlet port (104); a bellows arrangement (118); and a switch (146) configured to be activated to open the outlet port (106) for releasing the oxygen stream through the outlet port (106). Also disclosed is a system comprising the oxygen pressure regulating device (100), a laminar flow element and a second conduit.

Dialysis systems and methods for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a dialysis machine for transferring dialysate to a patient from a dialysate source. The dialysate may flow from the dialysate source through a cartridge or cassette (e.g., a disposable cartridge or cassette) positionable within the dialysis machine. The cassette includes a fluid flow channel. The dialysis machine includes a heating chamber for in-line heating of the dialysate in the fluid flow channel. The fluid flow channel is arranged and configured to provide turbulent flow of the dialysate through the fluid flow channel to provide increased heat transfer from the heating chamber to the dialysate.

An exhalation valve arrangement includes an upstream breathing gas duct, which extends along a first duct path, a downstream breathing gas duct, which extends along a second duct path, and a valve assembly having a valve body and a valve seat, which valve assembly is provided such that, in the event of a predetermined first breathing gas overpressure in the upstream breathing gas duct relative to the downstream breathing gas duct. The valve assembly permits an exhalatory breathing gas flow from the upstream breathing gas duct to the downstream breathing gas duct and, in the event of a predetermined second breathing gas overpressure in the downstream breathing gas duct relative to the upstream breathing gas duct, the valve assembly blocks a gas flow from the downstream breathing gas duct to the upstream breathing gas duct.

A biocontainment assembly for use with a patient suspected of having or diagnosed with a transmissible disease(s) capable of respiratory, airborne, contact, or droplet transmission includes a housing configured to be positioned over and at least partially enclose a head, neck, and/or torso of the patient. A sidewall of the housing includes an open portion contiguous with an at least partially pen bottom portion of the housing, sized to fit over at least a portion of the head, neck, and/or a torso of the patient. The housing also includes an airflow opening for evacuating fluid from an interior defined by the housing. The assembly also includes a drape configured to extend across the open portion of the sidewall having a first portion removably connected to the housing and an opposing second portion configured to be draped over the torso, abdomen, waist, and/or legs of the patient.

The present invention relates to a dialysis machine having an extracorporeal circuit in which a dialyzer is located which has a chamber on the blood side which is flowed through by blood and a first pressure sensor, which is located upstream of the chamber on the blood side in the direction of flow of the blood, for determining a first pressure value and a second pressure sensor, which is located downstream of the chamber on the blood side in the direction of flow of the blood, for determining a second pressure value, wherein the dialysis machine has first means for determining the pressure difference between the second pressure value and the first pressure value, second means for determining the dynamic viscosity of the blood on the basis of the determined pressure difference, of the blood flow rate through the chamber on the blood side and of one or more characteristic properties of the dialyzer and third means for determining the hematocrit or the hemoglobin value of the blood on the basis of the determined viscosity, and wherein the dialysis machine has a control or regulation unit which is configured such that it sets the blood flow rate and/or the dilution rate and/or the ultrafiltration rate such that the time change of the hematocrit and/or of the hemoglobin value does not exceed a limit value or lies in a desired value range.

An apparatus for administering a respirable gas to an individual includes a body receivable against a facial area for enclosing a respiratory organ, a vacuum hose, and a scavenger valve. The body is cup shaped, and includes a first side and a second side. An inhalation member extends from the first side of the body. An exhalation member extends from the second side of the body. The vacuum hose is for coupling a vacuum source to the exhalation member. The scavenger valve is coupled to the vacuum hose. The inhalation member is for administering respirable gas into the body, the exhalation member is for exhausting exhaust gas from the body into the vacuum hose, and the scavenger valve is for exhausting exhaust gas therethrough from the vacuum hose to an atmosphere.

Implementations of a delivery device and method are disclosed. One implementation is a delivery device comprising a flow chamber with an inlet port for receiving a fluid flow in the flow chamber, and an outlet port for exiting a material from the flow chamber. The flow chamber may include a formation portion in which a suspension of the material is formed, and a collection portion that directs the suspension toward and/or into the outlet port. An amount of the material may collect in the collection portion adjacent the outlet port. The device may further comprise an insertion port for permitting insertion of the material in the flow chamber, and/or a pusher operable to move the amount of material through the outlet port. Related devices and methods also are disclosed.

A nebulizer assembly for a respiratory device is provided having a housing defining a chamber. The housing also has a nebulizer port configured to receive a nebulizer to discharge atomized medication into the chamber. An outlet of a handle is coupled to the inlet of the housing. A hose is coupled to an inlet of the handle. A patient interface is coupled to the outlet of the housing. Air flows from the hose to the patient interface via the handle and the housing. The air mixes with the atomized medication within the chamber.
