A vascular graft includes deformable sleeves that include an electrical component. The electrical component can be variable-resistance or piezoelectric, in embodiments, such that deformation of the sleeves due to pressure changes create or modify an electrical signal. A transponder can then transmit information relating to the pressure inside and outside of the vascular graft.

Method for sterilising a body fluid drainage system for handling a body fluid ex vivo. The body fluid drainage system comprises a chamber. The method comprises the steps providing a container containing a surface protective fluid to be released into the chamber of the body fluid drainage system, subjecting the container to radiation sterilisation, inserting the container into the chamber of the body fluid drainage system, and subjecting the chamber containing the container to gas sterilisation. A body fluid drainage system for handling a body fluid ex vivo. The body fluid drainage system comprises a chamber. The body fluid drainage system further comprises a container containing a surface protective fluid. The container is arranged to release the surface protective fluid into the chamber. The surface protective fluid is sterilised by radiation sterilisation. An outer surface of the container and at least the chamber of the body fluid drainage system is sterilised by gas sterilisation.

Applicators for applying an on-skin assembly to skin of a host and methods of their use and/or manufacture are provided. An applicator includes an insertion assembly configured to insert at least a portion of the on-skin assembly into the skin of the host, a housing configured to house the insertion assembly, the housing comprising an aperture through which the on-skin assembly can pass, an actuation member configured to, upon activation, cause the insertion assembly to insert at least the portion of the on-skin assembly into the skin of the host, and a sealing element configured to provide a sterile barrier and a vapor barrier between an internal environment of the housing and an external environment of the housing.

The present disclosure generally relates to pressure detection technology, and in particular, to a pressure sensor, a method of fabricating a pressure sensor, and a pressure detecting device. The pressure sensor may include a flexible nanopaper, and a graphene film on one side of the flexible nanopaper.

A mask apparatus including a mask body that defines a communication hole, a sensor mounting portion that extends from a front surface of the mask body, that surrounds the communication hole, and that defines an installation space therein, a seal coupled to a rear surface of the mask body and configured to define a breathing space between the mask body and a user, a pressure sensor accommodated in the installation space and configured to sense air pressure inside the breathing space that is in communication with the communication hole, and a film disposed in the installation space and configured to restrict permeation of moisture from the breathing space into the installation space through the communication hole.

A module for an oscillometry system of the type having an oscillatory flow source, the module comprises an enclosure adapted to be releasably connected to a core assembly of the oscillometry system. The enclosure defines a breathing flow pathway adapted to be in fluid communication with the oscillatory flow source. A user port is at a first end of the breathing flow pathway configured for receiving a breath of a user. A calibration file specific to the module is programmed as a function of the breathing flow pathway and configured for being used by the oscillometry system to assess breathing parameters for the user.

A patient monitoring sensor having a communication interface, through which the patient monitoring sensor can communicate with a monitor is provided. The patient monitoring sensor includes a light-emitting diode (LED) communicatively coupled to the communication interface and a detector, communicatively coupled to the communication interface, capable of detecting light. The patient monitoring sensor includes hydrophobic materials provided around the light-emitting diode and the detector, wherein the hydrophobic materials reduce water absorption and prevent bacterial growth within the sensor.

A medical apparatus includes a therapy component for performing a therapeutic procedure on the patient. The therapy component includes sensing circuitry for sensing electrical signals from one or more sensing electrodes of the therapy component that are placed on and/or in the patient. With the medical apparatus powered on, a determination is made as to when the therapy component is actively engaged in performing the therapeutic procedure on the patient. When the therapy component is actively engaged in performing the therapeutic procedure on the patient, the one or more sensing electrodes of the therapy component are electrically connected to the sensing circuitry. When the therapy component is determined to not be actively engaged in performing the therapeutic procedure on the patient, the one or more sensing electrodes of the therapy component are electrically isolated from the sensing circuitry.

Apparatus and methods related to an underbody support for supporting a body of a being, such as during surgery to prevent contact pressure injuries. In certain embodiments, the underbody support may include one or more inflatable chambers enclosing a volume. At least one of the inflatable chambers may include one or more compression sensitive switches for monitoring the volume of the inflatable chamber, and the one or more compression sensitive switches may be located within the inflatable chamber. In some embodiments the one or more compression sensitive switches are sized to close when the said inflatable chamber is deflated to a desired residual volume.

An ambulatory monitor includes a conductive adhesive for electrically coupling a data recording module with a patient adhereable flexible patch. The ambulatory monitor includes a skin adhereable flexible patch and a data recording module that can be mounted to and demounted from the patch.
