Abstract: Various embodiments relate to catheter locking solutions and catheter locking therapies with use of trisodium citrate and ethyl alcohol, and in particular 4.0 to 15.0 weight/volume % trisodium citrate as an anticoagulant component and/or an antibacterial component and 15.0 to 25.0 volume/volume % ethyl alcohol as an antibacterial component. Use of the catheter locking solution and catheter locking therapy can reduce treatment failure during medical procedures that may employ catheters to supply treatment by at least significantly reducing the risks associated with bloodstream infections, catheter system malfunction, emboli formation, patient discomfort, and patient illness. These benefits can be partially due to the synergistic antibacterial effects of the trisodium citrate and ethyl alcohol in solution, generating an effective catheter locking solution with minimal concentrations of ethyl alcohol.

Abstract: A therapeutic substance delivery device is provided for delivering therapeutic substance to the subject. A sterile fluid path includes a needle at an upstream end of the sterile fluid path and an injection assembly at a downstream end of the sterile fluid path. The delivery device engages with a prefilled therapeutic substance reservoir, such that a disinfection chamber is defined between the sterile fluid path and the reservoir. The needle penetrates the disinfection chamber and subsequently the reservoir when the therapeutic substance delivery device and the reservoir are engaged with one another. A disinfection assembly is disposed within the delivery device and configured to disinfect the disinfection chamber prior to the needle penetrating the disinfection chamber. Control circuitry activates the disinfection assembly, terminates the activation of the disinfection assembly, and subsequently drives the needle to penetrate the disinfection chamber and subsequently the reservoir.

Abstract: Embodiments of the invention relate to devices, systems, and methods for selectively emitting scent control material responsive to local conditions of a scent control device. The local conditions may dictate the effectiveness of a given set of output parameters of a scent control device. The scent control device accepts as input, one or more conditional inputs carrying information about the local conditions around the scent control device, such as weather conditions, elevation, barometric pressure, or functional status of the scent control device. Operational programs corresponding to the conditional inputs may be automatically selected based on the combination of conditional inputs to cause the output parameters of the scent control device to match or take into account the local conditions. The scent control device then outputs scent control material such as ozone at a rate effective to control one or more scents to a level that is not perceivable by animals or humans.

Abstract: A room decontamination systems, controllers and methods for decontaminating a room. The room decontamination system may be a UV room decontamination system that uses UV radiation to perform a decontamination operation in the room. A controller may determine whether safe conditions for decontamination exist and initiate a decontamination operation on the basis of whether they exist. Determination of safe conditions for decontamination may be based on light actuation detection and/or sensor data, which may include presence detector data and door sensor data. Determination of safe conditions for decontamination may include a determination of whether sensors are functioning properly. The controller may also determine whether decontamination operations are required on the basis of the historical condition data, for example on the basis of whether the room has been occupied since the last decontamination operation.
