The present invention relates to a member (14, 24, 26) of a patient interface (10) for providing a flow of breath-able gas to a self-ventilating patient (12). The member (14, 24, 26) includes a wear-out indicator (32) for indicating a wear-out of the member (14, 24, 26) to the patient (12). The wear-out indicator (32) includes an elastic structure (34) that appears in a first colour in an unstressed condition and is configured to re-versibly change its apparent colour when being stretched and re-turned to its unstressed condition again. The elastic structure (34) is configured to indicate a wear-out of the member (14, 24, 26) by appearing in a second colour in its unstressed condition when the structure (34) has lost at least a part of its elasticity, wherein the second colour is different from the first colour.

This disclosure relates to a medical device including a hard part and a converter. The hard part has fluid paths for conducting a medical fluid through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the medical fluid is present in one of the fluid paths. At least a section of the converter is applied or superimposed to the hard part by at least one additive application method.

The invention relates to a non-heated humidification device comprising a wick; a chamber for holding water in contact with the wick; and a gas inlet to the chamber, wherein the chamber and wick are configured to humidify gas passing through or over the wick at ambient conditions. The device may be modular and attachable to a flow generator. The device may comprise dual gas circuits and a control system for controlling the gas flow through the gas circuits in order to control the humidity of the gas output.

This disclosure relates to a medical device including, a hard part, a converter, and a conductive path. The hard part has fluid paths for guiding a medical fluid, in particular blood, through the hard part. The converter is arranged to measure a characteristic of the medical fluid while the fluid is present in one of the fluid paths. At least a first section of the converter or of the conductive path is applied to or superimposed on the hard part by a first additive application method. At least a second section of the converter or of the conductive path is applied to the hard part by a second application method. The first and the second additive application methods differ from each other.

Implantable and/or insertable devices having a near-IR fluorescing material that allows the device to be visualized through a patient's skin. Also described herein are apparatuses for imaging devices having a near-IR fluorescing material, and methods of imaging devices having a near-IR fluorescing material from within the body, including methods of modifying an implanted device having near-IR fluorescing material.

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

A cushion member (2) is for a patient interface device. The cushion member includes a body portion (4) having a first end (6) and a second end (8) disposed opposite the first end, the body portion defining a passage (5) therethrough, and a support portion (10) extending from the second end into the passage. The support portion includes a first portion (12) and a second portion (14) disposed on or in the first portion. The support portion is movable from a first configuration to a second configuration responsive to a change in environment.

The present disclosure relates to a colorimetric aerosol detection device for detecting target compounds in an aerosol generated from an aerosol delivery device. The colorimetric aerosol detection device includes a tubular housing with a first open end (which can be configured to engage a mouthpiece of the aerosol delivery device) and a second open end (which may be configured as a mouthpiece) such that a stream of vapor can pass through the tubular housing in a direction from the first open end to the second open end. A colorimetric indicator material is located inside the tubular housing, and is configured to signal detection of a target compound in the vapor stream by a change in color visible to the user through a transparent or translucent portion of the tubular housing.

Reduced-pressure sources, systems, and methods involve using a vacuum pump that is disposed within a sealed space to produce reduced pressure. The exhaust from the vacuum pump is exhausted from the sealed space through pores in an enclosure member that is made of a polymeric, porous, hydrophobic material. Other devices, systems, and methods are disclosed.

A monitoring connector for a patient ventilation system serves for connecting to a breathing air tube portion for conducting ventilation air to a patient and for connecting the breathing air tube portion to a patient air interface. The connector has a control/regulation unit and at least one sensor for capturing a breathing air parameter which is in signal communication with the control/regulation unit. According to one aspect, the connector has a signal data memory for at least temporarily storing signal data. According to a further aspect, the sensor is configured as to measure the breathing air parameter in contact with the breathing air. According to one further aspect, the sensor is configured as to measure the breathing air parameter without contact. According to another aspect, the control/regulation unit has a plurality of signal transmission interfaces. This results in a connector which can be used flexibly and adapted to the respective requirements.
