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 resuscitation bag system (1) useable for resuscitating a person in cardiac arrest, and having a gas control unit (90) with a first valve (92) fluidly connected to a first (922) and to a second conduit (923), the first (922) and second conduits (923) being arranged in parallel and further fluidly connected to the first conduit element (56), the first conduit (922) having a first flow restriction (924) configured for limiting the gas flow to a first flowrate, and the second conduit (923) comprising second flow restriction (925) configured for limiting the gas flow to a second flowrate, with the second flowrate being less than the first flowrate.

Headgear for a patient interface includes at least one headgear strap and an indicator provided to the at least one headgear strap structured to indicate attainment of a desired adjustment setting of the headgear in response to headgear tension applied to the at least one headgear strap.

Add-on module (100) for logging the value of an expelled dose from a pen-type drug injector (200), comprising a magnetic sensor system comprising first and second sensor means (745/746) as well as a mechanical dose setting and expelling mechanism comprising a magnetic clutch element (240/740) which rotates during drug expelling. The system further comprises processor means configured to determine (i) on the basis of measured values from the first sensor means, a rotational position of the clutch element, (ii) on the basis of measured values from the second sensor means, a high-speed condition in which the rotational speed of the clutch element exceeds a given threshold level, and (iii) indicate an error state if the high-speed condition is detected.

A dressing for treating an open abdominal cavity with negative pressure. In some embodiment, the dressing may comprise a viscera contact layer capable of communicating a negative pressure to the viscera and capable of forming flow paths for a fluid through the contact layer; a fluid manifold capable of being disposed adjacent to the contact layer and capable of communicating a negative pressure to a tissue and capable of forming flow paths for a fluid; and a sensor capable of acquiring data associated with strain in one or more of the fluid manifold and the viscera contact layer

The present invention relates to a member (14, 24, 26) of a patient interface (10) for providing a flow of breathable gas to a self-ventilating patient (12). The member (14, 24, 26) comprises 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) comprises an elastic structure (34) that appears in a first colour in an unstressed condition and is configured to reversibly change its apparent colour when being stretched and returned 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.

A flexible self-adhesive label comprising a radiation-sensitive indicator for a syringe, the syringe comprising a barrel part with a front part and a rear part, having a tip at the front part, a piston at the rear part, and an exterior surface with a marking thereon. The label is attached to at least one part of the syringe and does not overlap with the marking. Also disclosed is a labeling method, kit and dispenser featuring such labels.

A universal respiratory detector for detecting a respiratory gas. The universal respiratory detector may include a plurality of layers with a visual indicator to quickly and reversibly change color to detect a respiratory gas parameter such as carbon dioxide. The color change may be visible from both sides of the detector. In some examples, the respiratory detector may be a biocompatible and conformable sticker for mounting on a person's face or an oxygen delivery device.

A medical drainage tube for transporting liquid from a liquid source to a liquid storage device, the medical drainage tube includes an inner surface which defines a lumen; an inlet for coupling to a liquid source and for receiving liquid into the lumen from the liquid source; an outlet for coupling to a liquid storage device and for transporting the received liquid from the lumen to the liquid storage device; and an indicator including an indicating agent which, when the medical drainage tube is in use, is configured to dissolve after being exposed to the liquid for at least 24 hours, thereby providing a trigger which notifies a user that the medical drainage tube requires replacement.

An assembly for coupling a dressing to a tube connected to a pump includes a hydrophobic film layer comprising a perforation extending therethrough, an indicator coupled to a first side of the hydrophobic film layer and positioned proximate the perforation, a felted foam layer coupled to a second side of the hydrophobic film layer and fluidly communicable with the indicator via the perforation, and a connection pad coupled to the first side of the hydrophobic film layer and coupleable to the tube.
