An electronic sanitizing device includes a germicidal light source and one or both of a red light source or a near infrared light source. The germicidal light source is configured to output germicidal light with a peak wavelength of 250 to 270 nanometers. The red light source is configured to output red light with a peak wavelength of 620 to 700 nanometers. The near infrared light source is configured to output near infrared light with a peak wavelength of 800 to 1200 nanometers.

An organ preservation system having; an organ chamber with a perfusate reservoir, a pump arranged to circulate perfusate, from the reservoir and passes the perfusate through a dialysis filter, oxygenator, and temperature and pressure sensors prior to entering the chamber where an organ is perfused. The organ rests on the platform such that perfusate leaving the organ flows into the perfusate reservoir. The dialysis filter having permeable tubes which allow perfusate constituents to be exchanged with dialysate flowing through the dialysis filter. The dialysate pass through an ion exchange resin removing selected constituents or waste products from the dialysate by absorption by the ion exchange resin. Following waste absorption, the dialysate is recycled to the dialyzer to again remove waste. Removing waste products from the perfusate by dialysis followed by removal of the waste products from the dialysate with the exchange resin, enables dialysate reuse for extended duration.

A method of reducing the risk of ventilator-associated pneumonia by decontaminating the oropharynx using a safe, antimicrobial light-emitting device.

An air-drying storage device for cleaned slides, including a storage box and a slide rack; an upper right corner in the storage box is fixedly provided with a miniature air intaking pump, a lower left corner in the storage box is fixedly provided with a miniature air expelling pump; a plurality of positioning plates are arranged on left and right inner walls of the storage box; the slide rack is detachably arranged between the positioning plates; an upper end of the storage box is provided with an electric control box configured to controls entire circuit. The air expelling pump and the air expelling pump accelerate the air flow rate inside the storage box; a sealing device and a magnetic device are arranged between edges of the box doors and edges of the storage box to prevent air leakage; an ultraviolet sterilization lamp sterilize the inside of the storage box.

A method of sterilisation, certification and traceability of liquid nitrogen, includes the steps of preparing a container, provided with an opening, in use, at the top, and pouring into it a batch of liquid nitrogen to be sterilised; providing an identification element uniquely associable with the batch of liquid nitrogen, said identification element including an indicator of the sterilisation state of the batch contained in said container configured to modify its appearance following exposure to ultraviolet radiation; associating the identification element with the container of the batch of liquid nitrogen to be sterilised, positioning it in a portion of said container, adjacent to said opening; carry out a batch sterilisation treatment through exposure to ultraviolet radiation for a predetermined period of time, to modify at least one characteristic of the indicator to certify the sterilisation of the batch.

A personal, portable, handheld UV light sanitizer (20) having a tubular housing (22) with a UV light source (32) for uniformly radiating a user's hand through a light transmittable outer wall (24) of the housing having a girth and length that enables substantially the entire the exterior surface of the outer wall to be covered by a user's hand when fully grasping the outer wall. A rearward annular wall (41) reduces any rearward light leakage and provides a bearing surface against which the edge of the user's hand may rest to prevent slippage. An annular forward wall (40) reduce forward light leakage and mounts actuation switches (36, 56), remote sensors (58, 60), a status indicator light (61) and an alarm speaker (59). When the skin surface sanitization mode switch (36) is actuated, skin sanitizing UV light radiation (42) radiates the inside of the user's hand for a preselected time period, unless there have previously been an excessive number of past hand sanitization cycles or too little time has passed since the last hand sanitization cycle (FIG. 9). Once energization, it is automatically deenergized after a preselected maximum time period (FIG. 9). Mounted to the front of the forward annular wall is another UV light source (51) that radiates UV light to suspect target surfaces spaced from the user's hand. A range finder (58) helps the user to hold the surface UV light source at the right distance from the target surface for effective sanitization, and energization is immediately terminated in response to an infrared sensor detecting that the surface UV light source is directed at a person's skin.

A system for irradiating a microplate may include a light engine with a plurality of light sources, such as light-emitting diodes, included in one or more linear arrays. The plurality of light sources are configured to emit germicidal irradiation, which is directed to the microplate by optical components, such as optical lenses positioned on top of each well of the microplate. The linear array is linearly movable so that as the linear array scans across the microplate, the optical components direct the germicidal irradiation to a plurality of surfaces of each well.

An arrangement, and associated method, for cleaning and disinfecting an endoscope having an internal channel accessible via an opening. The arrangement includes: a support structure; at least one tray including at least one fixture arranged to maintain the endoscope in the desired position within the tray; a rack arranged to support the tray; a control unit arranged to control and operate the arrangement; a user interface connected to the control unit and arranged to make it possible for an operator to indicate the type of endoscope arranged in the tray; an optical device connected to the control unit and configured to confirm the type of endoscope arranged in the tray; a robotic device operated by the control unit and arranged to clean the at least one channel in the endoscope arranged in the tray; and a disinfector device arranged to enclose the tray and disinfect the endoscope.

A disinfection tunnel includes an enclosure, an ozonated water tank, an ozonated water generator, a set of nozzles, a mist generator, and a processor. The ozonated water generator generates ozonated water and stores the ozonated water in the tank. When a person enters the enclosure, the processor starts the mist generator. The mist generator receives ozonated water from the tank, turns the ozonated water to a mist of ozonated water, and pumps the mist of ozonated water to the nozzles. The nozzles spray the mist of ozonated water inside the enclosure for a time period.

Apparatuses for sanitizing and/or sterilizing a dental/orthodontic appliance are described herein. These apparatuses may include an internal chamber in which one or more sanitizing/sterilizing modes, such as UV light (e.g., UVC light), ultrasound, heat, etc. may be applied to an appliance.
