The current pandemic due to Covid-19 stresses the importance of effectively treating highly contagious and deadly infections. The described medical device is meant to help the medical community by enabling them to treat patients more effectively. The delivery mechanism focuses on the mucous membrane. It is noninvasive and easy to use by patients directly. The device is hand-held, with incorporated germicidal UVC lights. It has two chambers connected by an internal application tip. The tip connects to a removable container which can be used with the prescribed treatment/therapy, vaccine, or viral testing fluid/reagent, as needed. Due to its versatility, non-invasive nature and germicidal properties, this device supports rapid response to infectious diseases, such as COVID-19. It may also further promote the development and use of different inoculation and drug techniques and delivery systems by enabling easy administration, via the mucous membrane.

Disclosed is a mutated lactonase belonging to the phosphotriesterase-like lactonase family, which increases the susceptibility of bacteria to antimicrobial agents as compared to the use of antimicrobial agents alone.

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.

A treatment chamber, preferably a medical treatment chamber for treating articles, preferably medical articles, devices and equipment, more particularly within the scope of sterilizing processes, including a treatment compartment which is surrounded by a lower wall element, a plurality of lateral wall elements and an upper wall element, wherein the treatment compartment is hermetically sealed or sealable for generating a desired internal pressure therein and can be temperature-controlled for generating a desired internal temperature therein, wherein at least one of the wall elements is formed of at least one hollow chamber section is disclosed.

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.

In a first aspect, the present invention relates to a process for producing a stable, injectable solution with low content of noradrenaline, which includes dissolving noradrenaline and optionally an excipient in deoxygenated or degassed water, filtrating the resulting noradrenaline solution in a nitrogen current, distributing the solution in a nitrogen current, and sterilization, preferably hot. The invention further provides a stable, injectable solution with low content of noradrenaline, substantially free of anti-oxidizing and preservative agents, as well as uses thereof in the medical and pharmaceutical fields.

A method and a system for producing a change in a medium. The method places in a vicinity of the medium an energy modulation agent. The method applies an initiation energy to the medium. The initiation energy interacts with the energy modulation agent to directly or indirectly produce the change in the medium. The energy modulation agent has a normal predominant emission of radiation in a first wavelength range outside of a second wavelength range (WR2) known to produce the change, but under exposure to the applied initiation energy produces the change. The system includes an initiation energy source configured to apply an initiation energy to the medium to activate the energy modulation agent.

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.

Disclosed herein are methods, systems, and devices for monitoring cumulative radiation. In one embodiment, a device includes a photodiode; an integrating capacitor electrically coupled with the photodiode; a voltage discharge switch electrically coupled with the integrating capacitor; and amplifier circuitry electrically coupled with the photodiode and the integrating capacitor. The amplifier circuitry is configured to maintain a substantially zero bias voltage between an anode and a cathode of the photodiode monitoring the cumulative radiation. The integrating capacitor is configured to provide a delta voltage representative of radiation received since the beginning of a charge cycle of the integrating capacitor.

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.
