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.

A method (600) of determining disinfection levels of a lighting device (130) is disclosed. The lighting device (130) is configured to emit disinfection light. The method (600) comprises: capturing (602), by a camera 108 of an augmented reality device (102), an image of a physical area (100), displaying (604), on a display (110) of the augmented reality device (102), the image, determining (606) an irradiation value of disinfection light provided or to be provided by the lighting device 130 on the target surface (140), wherein the irradiation value is determined based on a location of the lighting device (130) with respect to the target surface (140) and based on properties of the disinfection light provided or to be provided by the lighting device (130), determining (608) a level of disinfection of the target surface (140) based on the irradiation value of disinfection light, and rendering (610), on the display (110) of the augmented reality device (102), an indicator (120) indicating the level of disinfection, wherein the indicator (120) is overlaid on the image of the physical area (100).

The present disclosure provides a pathogen inactivation method, which is low-frequency sonication together with illumination of a photosensitizer-containing blood sample; and the low-frequency sonication is conducted at a frequency of 15-500 KHz. Through the combination of sonication and photochemical pathogen inactivation technology that enhance and complement each other, the blood pathogen inactivation method provided by the present disclosure enhances a pathogen inactivation effect, reduces a dosage of the photosensitizer, photosensitizer-related blood quality damage, energy demand for the illumination, and pathogen inactivation treatment time, increases the blood illumination thickness for effective pathogen inactivation, saves illumination bag materials, shortens the size of illumination equipment, saves costs, and helps the pathogen inactivation technology go to the market.

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 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 present disclosure relates to light emitting devices, systems and methods for use in animal nests, such as mink nests or piglet nests, for enhancing the formation of ND3 in animals and minimizing the microbial pressure in the animal nest, while providing the animals with an improved resting condition. A light emitting device comprises at least one UVB light source, wherein the light emitting device is configured such that UV light below 285 nm is not emitted from the device, visible light between 380 and 750 nm is not emitted from the device, and light in a wavelength interval of 290 nm-315 nm is emitted from the device.

Efficient and adequate disposal of medical infectious waste is proportional to the reduction of the spread of infectious diseases and the disease itself among humans. The essence of this invention is that infectious medical waste is in a timely, fast, efficient, simple, and environmentally friendly safely disposed of and turned into inert-municipal waste. Previous methods and devices for the disposal of infectious medical waste involved long-term procedures for the collection, sorting and storage of infectious medical waste, which increases the risk of secondary infections. This invention skips the process of collecting, sorting and storing medical infectious waste, and the entire process in the invention takes place in three unbreakable phases whose end product is municipal-inert waste. It is important to emphasize that with this invention, even the smallest amount of infectious medical waste will be disposed of immediately in an appropriate manner. And as a result, a maximum control over all medical infectious waste is achieved.
