The invention relates to a system for storing and distributing a gaseous mixture formed of NO/N.sub.2, comprising a container (6) containing an NO/nitrogen mixture equipped with an in-built pressure regulator (8) with an internal passage (22) for gas made of stainless steel and means for regulating the expansion of the gas collaborating with an expansion valve (27) and a valve seat (28) made of stainless steel. A first outlet coupling (21a) referred to as a ‘pressure’ outlet delivers the gas at low pressure and a second outlet coupling (21b) associated with a flow meter device comprising calibrated orifices and a flow rate selection member delivers the gas at several different flow rates. The invention also relates to an installation for distributing a gas containing NO to a patient comprising a ventilator (1) delivering a gas containing oxygen and to a system for storing and distributing a gaseous mixture formed of NO/N.sub.2 according to the invention.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

This disclosure includes wound dressings and systems for effluent management of topical wound therapy and related methods. Some devices, which are configured to dilute therapeutic gas effluent flowing from a dressing, comprise a therapeutic gas source configured to provide therapeutic gas to the dressing; a container comprising a sidewall that defines a chamber configured to receive therapeutic gas effluent from the dressing; a negative pressure source configured to be coupled to the container such that the negative pressure source can be activated to draw fluid from the dressing through the chamber of the container; and a diluent gas source configured to deliver a diluent gas to dilute therapeutic gas effluent before the therapeutic gas effluent enters the negative pressure source.

A blood loop system for controlling blood oxygen saturation includes a conduit loop, a pump, a flow cell, a matter source, an aeration chamber, a collection chamber and an oxygen probe. The pump is coupled to the conduit loop and positioned to circulate blood through the conduit loop. The flow cell is positioned to measure a characteristic of the blood circulated through the conduit loop. The matter source includes a gas. The aeration chamber is coupled to the conduit loop and is in fluid communication with the matter source to enable the gas to combine with the blood. The collection chamber is in fluid communication with the aeration chamber and is positioned to receive the blood. The oxygen probe is positioned to measure an amount of oxygen in the blood.

In order to acquire patient respiratory information during oxygen concentrator operation, it is necessary to separate patient respiration components and variable pressure components associated with PSA from the measured data of the patient respiration pressure. Provided is a respiratory information acquisition device which acquires respiratory information of a patient and which is used fora PSA-type oxygen concentrator, including a pressure detection unit for detecting pressure in conduit and/or a flow rate detection unit for detecting a gas flow rate in the conduit, and a calculation unit for extracting oxygen respiratory information from detected pressure data and/or flow rate data, wherein the calculation unit estimates a fluctuation component which does not depend on respiration of the patient based on detected data and information related to an operation state of the oxygen concentrator obtained from the oxygen concentrator, and extracts respiratory information by removing the fluctuation component estimated from the detected pressure data and/or the flow rate data.

A method of forming a stream having a therapeutic concentration of nitric oxide (NO) is disclosed, along with an apparatus and system suitable to accomplish this method.

The present technology is directed to ventilator systems that can provide both ventilation therapy and oxygen therapy. The systems described herein may include a ventilation assembly that can provide inspiratory gas to a patient circuit and an oxygen assembly that can provide pulses of oxygen to an oxygen delivery circuit. In some embodiments, the oxygen delivery circuit is distinct from the patient circuit. For example, the patient circuit can include a corrugated conduit coupled a ventilation mask, and the oxygen delivery circuit can include a nasal cannula. The ventilation mask can be positioned over the nasal cannula so that the patient can receive both the inspiratory gases and the pulses of oxygen.
