A UV-C generator is provided where multiple UV-C LEDs are provided around a work area (e.g., a tube) in order to sterilize contaminants in that work area (e.g., virus and/or bacteria) to provide a sterilization device for substances in, or flowing through, the work area. The tube may gates to change the speed and/or direction of a flowing working substance and may have a spiraling channel in the tube such that the length of travel in the spiraling channel is longer than the tube. Such UV-C generator devices may be utilized, for example, to sanitize air flowing through devices such as a ventilator or face mask.

A UV-C generator is provided where multiple UV-C LEDs are provided around a work area (e.g., a surface) in order to sterilize contaminants in that work area (e.g., virus and/or bacteria). The sterilization device can be utilized, for example, in a wand, broom, set distance surface sterilizer, hand sanitizer, foot sanitizer, conveyer sanitizer, or any other sanitizer. Mating structures may be included to mate multiple devices to extend work area that may be impacted. The devices may be portable and may include one or more rechargeable batteries.

A hands-free object sanitization system is provided where multiple UV-C LEDs are provided around a work area (e.g., a surface) in order to sterilize contaminants located on objects placed in that work area (e.g., virus and/or bacteria). Objects may travel through the work area without direct human intervention so that a hands-free sanitization system is provided. For example, objects may be dropped through a working area so that gravity provides a transport force through that working area.

An UV-C device may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-C in a particular direction and at a particular size and shape. Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Sound suppression compartments may be placed around a UV-C generating device inlet and/or a device outlet to reduce sound from the UV-C generating device. Human perceivable (e.g., audible, tactile, and/or visual) notifications may be utilized to provide notification of different modes of operation and/or different efficacy levels (e.g., percent ranges of inactivation of a particular or multiple particular viruses, bacteria, spores, etc.

A UV-C Amplifier is provided where multiple UV-C LEDs are provided around a work area (e.g., a hollow cylinder) in order to sterilize contaminants in that work area (e.g., virus and/or bacteria) to provide a sterilization device for substances in, or flowing through, the work area. The sterilization device have, for example, mating structures so that the device may be mated with other devices such as, for example, a ventilator or face mask. The sterilization device may be portable and may include one or more rechargeable batteries so that the device can sterilize material flowing into, through, and/or out of one or more devices such as a ventilator or face mask.

An air sanitization device is provided where a UV-C generator applied UV-C to infected air for sterilization and then the sterilized air is used to cool heat sinks attached to the UV-C. One or more fans can be utilized to push and/or pull air through the device. For example, the fans may create airflow in the device above, for example 200 liters per minute or above 400 liters per minute. Accordingly, a closed air system with a fan may push air through a UV-C generation device to sanitize air and the sanitized air may be pushed over a heat sink attached to the UV-C generation device and then pushed out of the closed air system into the environment. Thus, sanitized air may be circulated by the fan while being air cooled in a manner that does not circulate contaminated air.

An UV-C device may include several UV-C light sources (e.g., UV-C LEDs) and such UV-C LEDs may have UV-C reflecting structures arranged to direct UV-C in a particular direction and at a particular size and shape. Doing so may, for example, increase the UV-C in a particular direction or working area. A UV-C generating device may be utilized in an air stream, such as an air duct, to sterilize air from that air stream. Air may be pushed out of an annulus at the end of an air inactivation device and an annulus outlet cone may be provided in the middle of the annulus to assist, for example, inactivated air in moving smoothly away from the device and reduce pressure at the annulus exit. A UV-C inactivation tube may have UV-C reflective structures at each end to permit air to flow through the tube while reflecting UV-C light back into the tube.

An array of high intensity UVC LEDs usable for in vivo reduction of patient viral load or ex vivo sterilization.

Techniques for emergency apneic oxygenation include a cannula having a longitudinal inner passage with an inner diameter. A distal portion has a first outer diameter greater than the inner diameter, and is made of shape memory material shaped to bend in a first direction along the inner passage. A cannula base has a second outer diameter greater than the first outer diameter. A distance from a distal end of the cannula to a proximal end of the distal portion of the cannula is less than a distance from a surface of a throat of a subject to a distal surface of an airway of the subject. The inner passage is configured to pass a catheter connected at a proximal end to an oxygen source. In various embodiments, the cannula is used with a trocar and, optionally, a system base, or supplied in a kit with a catheter.

A hygiene filter for a device for artificial respiration, having at least one filter for filtering microorganisms and/or solid particles from a respiratory air volume flow, and a device for artificial respiration, having a holding device within the air intake region. The filter material is designed as a seal against the respiratory air volume flow conducting elements such that the risk of the occurrence of secondary air is reduced.
