The disclosure relates to a microbicidal composition with excellent action of limiting a decrease in durability of synthetic adhesives as well as high microbicidal action. The microbicidal composition contains 0.03 to less than 1.0 mass % of peracetic acid, 0.045 to less than 1.5 mass % of hydrogen peroxide, and 0.036 mass % or more of glycine.

Embodiments of the present disclosure disclose a multipurpose ultraviolet (UV) floor curing device. The device includes a mobile carriage, a UV panel, and a control device. The mobile carriage is configured to move on a floor applied with a photocurable coating. The UV panel is coupled to the mobile carriage and removably secures a plurality of radiation units configured to emit UV light of a predetermined intensity capable of curing the photocurable coating. The UV panel is configured to transition between a floor configuration and a non-floor configuration. The control device configured to drive the UV panel for the plurality of radiation units to project the UV light towards the ground substantially underneath the UV panel in the floor configuration and towards elevated surfaces proximate to the ground in the non-floor configuration.

An embodiment of the present disclosure relates to a sterilization module comprising: a light source module that generates light; a light guide which extends in a first direction and into which the light is incident; and a body having an upper surface that is open and supporting the light guide disposed therein, wherein the light guide includes a first side and a second side disposed opposite the first side in the first direction, and the light source module is disposed on the first side of the light guide to allow the light to be incident on the light guide.

The present disclosure discloses a pool-cleaning robot including a housing defining a receiving chamber therein, a power assembly, an underwater germicidal lamp assembly, a filter assembly, and a pump assembly. The housing defines a water inlet and a water outlet which are fluidly communicated with one another. The pump assembly is configured to drive the water flowing into the receiving chamber and being filtered by the filter assembly. The underwater germicidal lamp assembly includes a base, a light source module, and a lamp cover. The light source module includes a light-emitting element. An area of the lamp cover corresponding to a light-emitting area of the light source module is a light-transmitting area. A light-emitting surface of the light-transmitting area is provided with a laminating film. The present disclosure further discloses the above described underwater germicidal lamp assembly.

A contrast therapy machine is disclosed. The contrast therapy machine includes a cavity that is sized and shaped to accommodate one or more human bodies. Single user contrast therapy machines may include an opening through a top surface permitting the human body from the neck up to be outside of the contrast therapy machine while it is use. The contrast therapy machine includes a heater and a cooler. The contrast therapy machine can switch automatically or be manually switched between one or more cooling cycles and one or more heating cycles. Heating cycles and cooling cycles may be customized.

An ultraviolet C self-sterilizing germicidal light airborne pathogen killing system for ultraviolet C self-sterilization of door access devices, such as door handles, door levers, door push plates for hand sanitation, which includes a door access device associated with a door jamb, a module affixed to the door access device, a source of electricity associated with the door access device, a device for electrically powering the module, a device for the module to sanitize air for hand sanitization, and a device for activating the module for hand sterilization. The system may be of varying sizes depending on room measurements/needs and the module may contain its own batteries, may run on direct electrical wiring using a concealed power transfer system or may use any related battery or power source. The module may also be functional when utilized as a stand-alone device without being associated with door access devices.

A treatment transducer for a generator of alternating magnetic fields for in vivo disinfection of electrically conductive surfaces of medical implants, which may be used with a wide variety of implants and medical devices. The treatment head includes an enclosure for enveloping a portion of a body in which an implant is to be treated, and which contains a plurality of transducers for converting a radio-frequency signal to generating a shaped alternating magnetic field.
