An anaesthetic halocarbon capture system is provided. The system includes a pressure-intolerant sleeve containing filter material for capturing one or more types of anaesthetic halocarbon prior to supercritical fluid extraction, and a pressure-tolerant housing into which the sleeve can be inserted so as to permit exposure of the sleeve contents to pressures required for supercritical fluid extraction.

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.

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.

An absorption system (100) and a process for absorption of gas from a medical apparatus (1) are provided. The absorption system includes a feed line (6), a discharge line (8), a filter unit (4) with a filter and at least one buffer storage device. The feed line establishes a fluid connection between the medical apparatus and the filter unit. The discharge line establishes a fluid connection between the filter unit and a fluid absorption unit (7). The gas is discharged from the medical apparatus and is passed through the feed line to the filter unit and from there through the discharge line to the fluid absorption unit. The filter filters at least one gas component out of the gas that is passed through the filter unit. The one or more buffer storage device absorbs and again discharges gas from time to time.

The present disclosure describes a ventilator. The ventilator includes tubing configured to receive an input gas and a flow outlet airline in fluid communication with the tubing. The flow outlet airline includes an airline outlet, and the flow outlet airline is configured to supply an output gas to a user via the airline outlet. The ventilator includes an aerosol generator in fluid communication with the flow outlet airline. The aerosol generator is configured to receive an input liquid through an inlet tube and transform the liquid input into an aerosol. The ventilator further includes a breath detection airline including an airline inlet, wherein the airline inlet is separated from the airline outlet of the flow outlet airline, and configured to receive breathing gas from the user during exhalation by the user via the airline inlet. A method of supplying respiratory gas containing an aerosol is disclosed.

A passive valve for use as a fixed leak valve. The valve includes a body having an internal chamber, first and second body ports in fluid communication with the chamber with the first port configured for fluid communication with a patient connection and the second body port configured for fluid communication with a ventilator, a body passageway in fluid communication with the chamber and with ambient air exterior of the body, and a check valve seal positioned to seal the body passageway to permit the flow of gas within the chamber through the body passageway to the exterior of the body and to prevent the flow of ambient air exterior of the body through the body passageway into the chamber. In alternative embodiments, the valve is incorporated into the patient connection or constructed as a separate part connectable to the patient connection.

A portable oxygen generating system is provided that comprises a reaction chamber, a feed system for providing and controlling hydrogen peroxide solution to the reaction chamber, and a cooling/condensing system for cooling the hot oxygen and water vapor leaving the reactor and condensing and removing water. The portable chemical oxygen generation system produces humidified, breathable oxygen, that is substantially free of hydrogen peroxide and other contaminants, at a controlled flow and temperature over an extended period of time.

A monitoring and control system of a molecular sieve oxygen plant generator comprising a PLC controller installed in an oxygen generator, which in turn is connected with an oxygen generator and an air storage tank. The system allows the generation of oxygen in situ and the control and monitoring is remotely controlled. The system comprises artificial intelligence for the monitoring, control and fault self-diagnosis.

Lightweight, portable oxygen concentrators that operate using an ultra rapid, sub one second, adsorption cycle based on advanced molecular sieve materials are disclosed. The amount of sieve material utilized is a fraction of that used in conventional portable devices. This dramatically reduces the volume, weight, and cost of the device. Innovations in valve configuration, moisture control, case and battery design, and replaceable sieve module are described. Patients with breathing disorders and others requiring medical oxygen are provided with a long lasting, low cost alternative to existing portable oxygen supply devices.

A composite ion conducting tube is made by wrapping a support material or ion conducting sheet to from a tube having overlaps of layers that are bonded. The ion conducting sheet or tape used to make the tube may be very thin and the tube may be formed in situ by wrapping the support material and then coating with ion conducting polymer. The ion conducting tubes may be used in a pervaporation module or desalination system. The ion conducting tubes may be spirally wrapped or longitudinally wrapped and may be very thin having a tube wall thickness of no more than 25 microns.
