Abstract: Ultraviolet light disinfection systems expose medical devices, surfaces, patients and healthcare clinicians to UV light having wavelengths consist with killing microorganisms. UV light systems may use logic to govern the operation of UV light sources so as to apply a disinfecting dose of the UV light. UV detectors measure UV light exposure. Enclosures contain medical devices and flood the medical devices with the UV light. Some enclosures accommodate a person. Some UV systems project UV light onto high-touch surfaces of a healthcare environment. Some systems may be deployed within a patient transport vehicle. Some UV systems may be incorporated into medical devices.

Abstract: An infusion system for in-line disinfection of a prepared infusate with UV light can include a vascular access device (“VAD”) and a UV light ring. The VAD can include an intracorporeal conduit, one or more extracorporeal conduits fluidly connected to the intracorporeal conduit, a hub between a proximal portion of the intracorporeal conduit and one or more respective distal portions of the one-or-more extracorporeal conduits, and one or more respective connectors of the one-or-more extracorporeal conduits. The intracorporeal conduit is configured to be percutaneously inserted into a patient, and the extracorporeal conduit is configured to remain outside a body of the patient. The UV light ring can be configured to encircle a portion of an infusion lumen of the VAD and irradiate the prepared infusate within the infusion lumen with the UV light for infusing a disinfected infusate into the patient during an infusion of the patient.

Abstract: A disinfection device for disinfecting a hub of a medical device includes a housing having a first end and a second end, a power source, an ultraviolet light source, and a connection mechanism located at the first end of the housing, wherein connection of the hub of the medical device to the disinfection device initiates a disinfection process configured to disinfect the hub. the ultraviolet source may be a light emitting diode with a peak of wavelength within the range of 100-400 nm (specific implementations being 225-264 nm) and the connection mechanism includes one or more of a screw thread, a channel, ridge, a friction fit connector, a magnet, or a ferromagnetic material. The disinfection device may include a port located on the second end, wherein the one or more port is configured for coupling to an external device and receiving a charge or power supply from the external device.

Abstract: A system and method for disinfecting medical devices includes a covering for a medical cart that exposes medical devices disposed on the cart to a disinfecting ultraviolet light. The covering includes a light emitting system that includes a number of UV light sources, such as LEDs, configured to define an ultraviolet light environment beneath the covering. The light emitting system may include one or more light pipes and/or optical fibers. systems and methods. An opaque layer of the covering contains the ultraviolet light environment beneath the covering. Portions of the light emitting system suspend from the covering so as to emit UV light between adjacent medical devices on the cart.

Abstract: A method of operating a security system includes sensing a security breach, and providing an indication to a user that an alarm signal will be issued in response to the sensing of the security breach. The indication perceptibly changes with time.

Abstract: A method of installing a security system includes transmitting an air-borne request signal to a security device. An air-borne reply signal is transmitted from the device in response to the request signal. The reply signal includes identification information corresponding to the device.

Abstract: A method of operating a security system includes providing a plurality of sensors, and detecting at least one event with the sensors. A decision whether to initiate an alarm signal is dependent upon the detecting by each of the sensors, which of the sensors has detected the at least one event, and what nonzero number of times a first of the sensors has detected the at least one event.

Abstract: An ankle rehabilitation device includes a foot platform movably disposed on a support arm coupled to and extending upwardly from a base. The foot platform is configured to pivot along a restricted pivot path configured to limit the user's ankle movement to plantar flexion, inversion and internal rotation in one direction along the restricted pivot path, and dorsi flexion, eversion and external rotation in an opposite direction along the restricted pivot path. A ball and socket type joint is coupled between the foot platform and the support arm, and has an aperture sized and shaped to limit movement of a coupling arm, and thus to limit movement of the foot platform. The device also includes resistance means, such as piston/cylinders, coupled to and between the base and the foot platform, for resisting movement of the foot platform with respect to the base. The piston/cylinder may be oriented transverse to all pivot axes of the foot platform to resist all movement of the foot platform.
