DEVICES, SYSTEMS, AND METHODS FOR STERILIZATION, DISINFECTION, SANITIZATION AND DECONTAMINATION

A sterilization, disinfection, sanitization, or decontamination system having a chamber defining a region, and a generator for creating a free radical effluent with reactive oxygen, nitrogen, and other species and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The system is used in sterilizing, disinfecting, sanitizing, or decontaminating items in the chamber or room and, with a wound chamber, in treating wounds on a body. The wound chamber may be designed to maintain separation from wounds being treated. Various embodiments can control moisture to reduce or avoid unwanted condensation. Some embodiments can be incorporated into an appliance having a closed space, such as a washing machine. Some embodiments may include a residual coating device that deposits a bactericidal coating on sterilized items.

HEMODIALYSIS SYSTEM INCLUDING ULTRAVIOLET CHAMBER(S)

A hemodialysis system including one or more ultraviolet chambers is disclosed. The hemodialysis system including a dialyzer arranged and configured to filter a patient's blood, a hemodialysis machine arranged and configured to pump, move, or the like dialysate through the dialyzer, the hemodialysis machine including an outlet valve and an outlet fluid flow path to pump or move dialysate from the hemodialysis machine to the dialyzer, and an inlet valve and an inlet fluid flow path to pump or receive dialysate from the dialyzer, and one or more ultraviolet chambers arranged and configured to kill bacteria, viruses, or a combination thereof. Thus arranged, by incorporating one or more ultraviolet chambers in strategic areas of the system, the ultraviolet chambers may eliminate, or at least greatly reduce, the possibility of cross-contamination in, for example, the dialysate, and thus eliminate the need for disinfecting the system between treatments.

20170348663 · 2017-12-07 ·

The invention relates to a method for treating a nanofibrillar cellulose hydrogel, wherein the method comprises the steps of: providing a nanofibrillar cellulose hydrogel, wherein the nanofibrillar cellulose is oxidized nanofibrillar cellulose, wherein the oxidation has been carried out through N-oxyl mediated catalytic oxidation of cellulose-based raw material, and has at most 50 μmol of aldehyde groups per gram of dry nanofibrillar cellulose; and subjecting the nanofibrillar cellulose hydrogel to a heat treatment.

HIGH-PRESSURE WATER DEBRIDEMENT SYSTEM
20230173550 · 2023-06-08 ·

There is disclosed a system and methods for debriding soft tissue from bone using a high-pressure water debridement system. One embodiment includes a cylindrical sleeve bounded by endcaps and having a drainage port positioned for effluent drainage. A central shaft is configured to receive a bone segment and is disposed along a longitudinal center of the sleeve and rotatively coupled between the endcaps. At least one high-pressure water nozzle is disposed on each side of the sleeve, each of which is positioned to impact the bone segment with a high-pressure water stream. A rotational actuator is configured to rotate the central shaft and the bone segment relative to the sleeve and the water nozzles such that when the high-pressure water nozzles are operational, the high-pressure water streams debride the bone segment. Other embodiments are also disclosed.

Wefted hair dryer
09826812 · 2017-11-28 ·

Systems, devices, and methods for drying wefted hair. Systems can include an enclosure for drying wefted hair by removing moisture from the wefted hair. The wefted hair can be hung on racks having a plurality of tines. The wefted hair can be placed on trays.

PLASMA GENERATION

A plasma torch having an open end from which a plasma plume is emitted in use is disclosed. The plasma torch includes a central cathode rod, a grounded conductive tube having an open end and being arranged around the cathode and spaced therefrom to form a first cylindrical cavity open at one end; and a high voltage electrode having a dielectric barrier material at a radially inward-facing surface thereof and being arranged around the grounded conductive tube and spaced apart therefrom to form a second annular cylindrical cavity open at one end. A constant direct current (DC) electrical power plus a high voltage pulsed electrical power is provided to the cathode producing an arc discharge in the first cavity between the cathode and grounded tube to generate a central thermal plasma emitted at an open end of the first cylindrical cavity. A high voltage alternating current electrical power or pulsed electrical power is provided to the high voltage electrode producing a dielectric barrier discharge in the second annular cylindrical cavity to generate a non-thermal plasma emitted from an open end of the second cavity as a halo around the central thermal plasma.
