This disclosure is directed to a medical device including a surface that has been roughened to provide a roughened surface that inhibits the adhesion of microorganisms on the roughened surface.

This disclosure is directed to a medical device including a surface that has been roughened to provide a roughened surface that inhibits the adhesion of microorganisms on the roughened surface.

The disclosure is a medical device system that applies pressure to biologic products in a container to inactivate pathogens (e.g., viruses, bacteria, including sepsis, fungi, parasites, prions, mold and other harmful microorganisms), or abnormal or damaged cells (e.g., cancer, carcinoma in situ, lipoproteins, lipids, antibodies), while preserving the desired cells and the efficacy of the biologic product (e.g., whole blood, plasma, red blood cells, platelets and cells derived from blood, bone marrow, stem cells, brain dura matter, bone graft, skin graft or other bodily sources, either allogeneic or autologous). The biologic product may be autologously sourced then processed and transfused or administered, or be allogeneicly sourced and then processed and transfused or administered.

A bulk HPP container (10) includes a flexible body portion (12) having closed off ends (14), at least one of which is depicted as being recessed to enable the containers (10) to be positioned end-to-end in an efficient manner, for example, when placed into an HPP pressure vessel, such as a wire wound vessel. One or more openings are provided in the body portion of the container with n appropriate closure for pumpable product to enter and exit the container. In this regard, an inlet valve (16) or other type of closure may be located at the opening in one or both of the ends of the container. Also, one or more outlet valves (18) or other type of closure are located at an opening on the body portion (12) of the container for emptying the container, for example, after HPP. The body portion 12) is composed of sufficient flexural strength and sufficient flexural modulus to enable the container to reduce in volume by from 0 to at least 30% while being rigid enough for reuse over a desired number of HPP cycles.

An apparatus, system, and method for contacting blood with ozone to kill microorganisms in the blood are described. The method involves injecting microbubbles of ozone containing gas into a flow of blood, preferably at a temperature of less than 12° C. The apparatus includes a blood flow conduit including a blood ozone contacting portion including a porous ozone injector.

A system and method for mitigating airborne contamination in a conditioned indoor environment utilizes one or more sensing modules configured to detect presence and/or concentration of particles and/or aerosols at different locations. A control module employs an artificial intelligence algorithm to selectively activate at least one mitigation module utilizing machine learning programmed rules and output signals from the sensing module(s). The mitigation module(s) are configured to take one or more actions to reduce presence and/or concentration of particles and/or aerosols in the conditioned indoor environment.

A method of follow-up decontamination operation for the polluted storage canister of a high activity nuclear waste storage facility, using needle and steel brushes driven by pneumatic tools for abrading the bottom and the inner wall of the storage canister to remove contaminants, a multi-level filter system for air filtration and removing pollutants in the storage canister, and a cover to be used in association with the pneumatic tools and the multi-level filtration system suitable to cap the storage canister, thus effectively block the exposure of contaminant of the storage canister to the external environment, achieving effective decontamination of the radioactive waste and reducing spreading to the environment.

A food processing and/or packaging device comprises at least one food chamber. Via a conduit system, the at least one food chamber is connected to a vacuum pump for generating vacuum in the at least one food chamber. For sterilizing the conduit system and/or the food chamber, a sterilization device is provided. The sterilization device comprises e.g. spray nozzles for introducing cleaning liquid into the conduit system. The cleaning liquid is separated by a liquid separator arranged upstream of the vacuum pump in flow direction.

An air purifier includes a shell, a wind turbine and an air filter layer. The shell includes at least one air inlet and at least one air outlet, and an air passage is defined between the at least one air inlet and the at least one air outlet. The wind turbine is located in the air passage. The air filter layer is located in the air passage and includes a filter screen. The air filter screen includes a carbon nanotube structure including a plurality of carbon nanotube films stacked and crossed with each other. The carbon nanotube structure includes a plurality of micropores. A diameter of the micropores is ranged from about 1 micrometer to about 2.5 micrometers.
