Apparatus is disclosed for ventilation using an airbag, which may also be operable manually. The apparatus comprises: means providing or penetrable to form an aperture in the airbag; retractable means provided separately from the airbag, for extending in the airbag; fixing means for fixing, by an operator, an end of the retractable means to the airbag via the aperture; actuation means, for repeatedly retracting the retractable means at least partially through the aperture in the airbag to collapse the airbag, and for enabling expansion of the airbag to an expanded state; and connecting means for connecting the actuation means to the airbag and for preventing environment egress of gas from within the airbag between the aperture and the actuation means.

A negative pressure wound therapy device can include a negative pressure source configured to be connected, via a fluid flow path, to a wound, a valve positioned in the fluid flow path and configured to, in an open state, permit supply of negative pressure from the negative pressure source upstream of the valve and, in a closed state, block supply of negative pressure from the negative pressure source upstream of the valve, a flow restrictor positioned in the fluid flow path, and a pressure sensor configured to measure a pressure differential across the flow restrictor. The device can include control circuitry configured to, in a normal operational mode, cause the valve to be in the open state and, in a test mode, perform at least one of a leak test, a flow test, or an excessive pressure test.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.

Methods and systems are provided for anesthetic agent leakage diagnostics. In one embodiment, a method for diagnosing leaks in an anesthetic vaporizer includes calculating a leakage rate based on measurements of an anesthetic agent level in a sump of the anesthetic vaporizer, the measurements received from a fluid level sensor at a first time and a second time, and outputting a maintenance alert responsive to the leakage rate exceeding a threshold.

An appliance is provided for negative-pressure therapy of wounds on the human or animal body in which, on the one hand, a substance is delivered to a wound bed (W) and, on the other hand, fluids, in particular an exudate and the delivered substance, are aspirated from the wound bed by negative pressure. The appliance has a suction pump housing, with a suction pump arranged therein for aspirating the fluids from the wound bed (W), and a fluid collection container for collecting the aspirated fluids. Moreover, the appliance has a first measuring device and a second measuring device. The first measuring device serves to determine the quantity of the aspirated fluids, and the second measuring device serves to determine the quantity of the substance delivered to the body.

A porous conduit may be suitable for use in treating a tissue site, and may include a central lumen and a porous wall positioned substantially concentric about the central lumen. The porous wall may have an open porous structure that may define a plurality of interconnected pores in fluid communication with one another. As part of a system, the porous conduit may be used with a manifold adapted to be positioned at a tissue site, a sealing drape adapted to cover the manifold to provide a sealed space relative to the tissue site, and a therapy device including a reduced-pressure source. The porous conduit may be disposed in the sealed space and in fluid communication between the sealed space and the reduced-pressure source.

Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure. In one approach, the breast pump assembly includes a breast adapter and a receptacle configured to cup the breast adapter, and the breast adapter is removable from the receptacle.

A sensor patch, system, and method for detecting a fluid leaked from a target site of a subject are provided. The sensor patch (100) includes a first detecting unit (127), a second detecting unit (128), and a patch body (110). The first detecting unit (127) includes a first pair of sensors (120A) respectively having a first end (121A) configured to be placed approximating the target site, while the second detecting unit (128) includes a second pair of sensors (120B) respectively having a first end (121B) configured to be placed away from the target site. Each sensor includes a conductive wire (125) and an insulating sheath (126) encapsulating the conductive wire (125) in a manner that a portion of the first end (121A, 121B) of the conductive wire (125) is exposed yet without directly contacting the subject's skin. The patch body (110) has an adhesive surface (104) for securing the first and second detecting units (127, 128) to the subject. The sensor patch enhances the detection specificity.

An infusion state detection system includes: a pump unit configured to deliver a liquid in an infusion line; a pressure detector configured to detect a pressure in the infusion line; and a determination processing unit configured to: when the pressure detected by the pressure detector is at a predetermined value or above, stop driving of the pump unit for a stop period, and determine an infusion state on the basis of a value of the pressure detected by the pressure detector during the stop period.

The present technology relates to systems and/or methods for enabling a respiratory device to be configured when a clinician or healthcare professional is remote from the respiratory device. One form provides a method of configuring a respiratory device, the respiratory device comprising a processor configured to control operation of the respiratory device in accordance with a plurality of operating parameters. The method comprises determining a combination of settings for the device from an identifier sent to the device, the identifier corresponding to the combination of settings, and configuring the respiratory device accordingly. Another form provides a method of verifying the configuration of the respiratory device by outputting an identifier corresponding to the combination of settings for the device, and determining the settings from the identifier.
