An UV-C device may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-C in a particular direction and at a particular size and shape. Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Multiple UV-C inactivation devices may be coupled in series and placed into a single housing for in order to increase the efficacy of the UV-C inactivation device. The inlet of the device may draw air using an inlet module attachment (e.g., a hood with one or more than one inlet hood) and may output air using an outlet module attachment (e.g., a duct to deliver air to an outflow air duct). Computational fluid dynamic software may be provided where UV-C inactivation devices may be positioned (e.g., manually or autonomously by an adaptive algorithm) to determine impact on airflow against various pathogens (e.g., Staphylococcus and/or SARS-CoV-2).

The present application relates to an oral irrigator, the oral irrigator includes at least a main body, a partition wall, a sterilization portion, and a control main board. By providing the partition wall, the first cavity and the second cavity are separated from each other, and the spray head is separately accommodated in the second cavity, and the first cavity is provided with the sterilization portion corresponding to the second cavity. The sterilization portion includes a UV lamp module. The second cavity and the spray head are sterilized through the UV lamp module, which effectively reduces the secondary pollution of the flushing fluid.

A laser device for dentistry has a body, a light source group, and a light guiding pipe. The body has an outer casing, an operating module, and a controlling module. The light source group is disposed in the body and has multiple light-emitting elements, a reflector, a collimating mirror, and a focusing mirror. Each light-emitting element is a laser diode, is disposed at a connecting portion of the body and is electrically connected to the controlling module. The reflector is mounted around the light-emitting elements. The collimating mirror is disposed on a side of the reflector away from the light-emitting elements. The focusing mirror is disposed on a side of the collimating mirror away from the reflector. The light guiding pipe is detachably connected to the connecting portion of the body and is located on a front side of the light source group.

Embodiments of the present disclosure relate to systems and methods for the application of vaporized chemicals in sterilization procedures, and systems and methods for controlling (e.g., distributing, moving, or exhausting) such chemicals. For example, embodiments of the present disclosure may relate to systems and methods for effecting terminal sterilization of medical products using vaporized hydrogen peroxide (VHP), and/or for the distribution of VHP to, or removal of VHP from, a sterilization system or parts thereof.

The invention describes stable high level disinfectant compositions with peracetic acid, organic acids, a fatty acid and a surfactant that are useful for the elimination of surface contaminants from a medical device such as an endoscope.

A first alternative to a composition for preventing or retarding degradation of a functional coating on a medical device comprising an antioxidant selected from gallic acid or a derivative thereof. A second alternative to a composition for preventing or retarding degradation of a functional coating on a medical device includes carboxymethyl cellulose or a derivative or salt thereof. The use of the compositions for preventing or retarding degradation of a functional coating on a medical device from reactive species generated during exposure of radiation, and a wetting agent comprising the compositions, are also provided. The wetting agent prevents or retards the hydrolytic degradation of the coating during the intended shelf-life of the wetted coated product.

Antiseptic caps that can be used to disinfect and/or protect medical connectors are disclosed herein. In some embodiments, the antiseptic cap can include a first chamber configured to be removably attached to the medical connector. Delivery systems for use with medical articles are also disclosed herein. In some embodiments, the delivery system comprises various dispensing systems for antiseptic caps and/or antiseptic cap holder assemblies. In some embodiments, the delivery system can be configured to permit the medical articles to be individually removable from the delivery system.

A multi-use disinfecting cap and method for disinfection and protection of a needleless IV injection port. The disinfecting cap has an upper chamber which contains a sterilizing solution and a low chamber which connects to a needleless IV injection port. The fluid can be manipulated to flow between the two chambers. When in use the cap protects and disinfects a needleless IV injection port when exposed prior to injecting medication into the needleless port and continues to disinfect and protect prior for any subsequent exposures. The cap is re-usable and provides a clear indication of the disinfecting solution and a datable top surface. The multi-use disinfecting cap may be removably clipped to the IV tubing and is shaped to prevent accidental rolling away if dropped.

Systems are disclosed which are programmed to receive data regarding a quantity and/or type of at least a subset of a plurality of disinfection sources for disinfecting an area or room and determining, based on the received data, operating parameter/s for one or more disinfection sources to disinfect the area or room. In addition, systems are disclosed which facilitate power redirection among multiple disinfection sources upon detecting a given area has received a predetermined dose of ultraviolet light. Furthermore, a method is disclosed which includes determining a schedule of locations to position a disinfection apparatus in a room or area to successively disinfect identified objects and/or surfaces in the room that are arranged between 2 and 4 feet from a floor of the room/area and tailoring one or more operating parameters of the disinfection apparatus to primarily disinfect the target objects and/or surfaces at each of the scheduled locations.

A catheter insertion aid may comprise: an insertion tip located at a proximal end of the insertion aid; a flexible bag; a self-sealing mating mechanism on the proximal end of the insertion aid; and a physical interface that helps a user hold and support the insertion aid against the body when inserting the catheter tube into the male or female urethral tract. The catheter insertion aid may mate with a urinary intermittent catheter with a catheter tube to be inserted into a male or female urethral tract to facilitate drainage of urine from a bladder into a receptacle. The flexible bag may surround the catheter tube with a first collar connection mechanism connecting to the insertion aid and a second collar connection mechanism connecting to a catheter funnel. The self-sealing mating mechanism may mate with the catheter funnel to create a hermetic seal that is substantially air- and water-tight. The catheter insertion aid may further comprise a lubrication reservoir that holds a lubricant to coat a thin layer of the lubricant on the catheter tube facilitating insertion of the catheter tube into the male or female urethral tract.
