AQUEOUS OZONE GENERATOR CARTRIDGE

An illustrative expendable or reconstructable ozone generator cartridge for an aqueous ozone delivery device, for example, for antimicrobial sanitizing and/or medical treatment, includes a housing for a water ozonating manifold, at least one ozone generating cell coupled to the manifold, and optionally a data logging and authentication feature. Advantageously, a water inlet, an aqueous ozone outlet, and an electrical connector of the ozone generator cartridge are simultaneously pluggable into and unpluggable from a docking station of the aqueous ozone delivery device, for example, a hand or implement washing and sanitizing device or a medical treatment device.

Gas treatment delivery systems and methods

The present disclosure provides apparatuses and systems for delivering a measureable absorbed-dose of a gaseous activating agent to a fluid including a biological liquid and/or cells. The apparatuses or systems include a gas-fluid contact device configured to controllably rotate or oscillate a control member having an interior surface in contact with the fluid and a control system configured to control rotation or oscillation of the contact member by the gas-fluid contact device. In some embodiments, the control system is further configured to control absorption of the gaseous activating agent by the fluid. The present disclosure also provides methods of treating a fluid including a biological liquid or cells with a gaseous activating agent to controllably activate the fluid.

GENERATING COLD PLASMA AWAY FROM SKIN, AND ASSOCIATED SYSTEMS AND METHODS

A cold plasma system and method for treating a region of a biological surface is presented. In one embodiment, the system includes: a housing; an air conduit within the housing; a first electrode configured proximately along the air conduit; a second electrode configured proximately along the air conduit and opposite from the first electrode; and a source of alternating current (AC) electrically connected with the first electrode. The source of alternating current is configured to generate cold plasma in the air conduit.

METHOD OF STERILIZATION OF BIOLOGICS
20220323621 · 2022-10-13 · ·

Methods of sterilizing biologics or biological components are disclosed wherein the biologic or biological component in solution or suspension form are formed using an annealing step during freeze drying so that a porous solid matrix which allows penetration of a sterilizing gas such as EtO to pass through. The annealing process decreases the particle size of lyophilized material as compared to other methods and provides a more uniform cake that is easy to reconstitute. In addition, the resulting lyophilized material made with the annealing step allows better penetration of the sterilizing gas for more effective and uniform sterilization of the material.

Magnetic Fluid Seal for Implantable Devices

Systems and methods for providing a magnetic fluid (MF) seal suitable for a fluid environment may provide a shaft and a magnet that is cylindrical or ring-shaped. A magnetic fluid may be present between the magnet and shaft. Additionally, pole pieces may also be provided, which are also cylindrical or ring-shaped. These pole pieces are positioned on the shaft so the magnet is sandwiched between the pole pieces. The magnet, pole pieces, and shaft, if magnetic, may attract and retain the magnetic fluid in an annular gap or region between the shaft and the magnet and/or the pole pieces. The magnetic fluid in the annular gap serves as a seal or barrier that prevents fluid from passing through when pressure is below a predetermined level.
