Systems and methods for cleaning and maintaining artificial airways sized for insertion within pediatric or neonatal patients (e.g., external diameters of less than 5 mm) are disclosed. The system includes a multi-port ventilator manifold configured to couple to a ventilation source, thereby forming a ventilator circuit with the patient. The manifold includes an occluder configured to advantageously reduce an amount of dead space in the manifold so as to prevent less of positive end expiratory pressure of the ventilator circuit and reduce the likelihood of broncho-pulmonary dysplasia of the patient, or even premature death.

The invention relates to automated devices for pro¬ducing aerosols of liquid disinfectants and for spraying same. A mo¬bile hygiene unit comprises a housing (1) containing a disinfectant spraying unit (2) with a spraying nozzle (3), a tank (4) containing disinfectant, a compressor (5), and a control unit (6). It further com¬prises a mechanism for regulating the droplet size distribution of the aerosol, including a pump (7), an electromagnetic valve (8), and a dosing nozzle (9) with an internal cylinder. The disinfectant spraying unit (2) comprises a shaped nozzle (3) having a nozzle head (10) of axisymmetric cross-section attached thereto, and a mixing chamber (11) for mixing disinfectant with compressed air, having two thread¬ed inlets for a pneumatic line (12) and a hydraulic line (13), said inlets being arranged at an angle of 180°. The dosing nozzle (9) contains an internal cylinder and a rod with a threaded tip. The mobile hygiene unit generates an aerosol in four droplet size distribution modes: dry fog (from 3.5 to 10 pm), wet fog (from 10 to 30 pm), mist (from 30 to 50 pm), and spray (from 50 to 100 pm). The invention allows highly precise regulation of the droplet size distribution of the aerosol in each mode without the need to change the spraying nozzle.

The robotic devices disclosed herein may sanitize environments comprising people.

The use of plasma to clean or sterilize items can be particularly advantageous for items that cannot be readily washed or cleaned by standard methods. The toxicity and complications generating sufficient plasma makes it hard to use for such purposes. The subject invention addresses the problem by generating a minimal amount of highly reactive plasma to sterilize an item. This is achieved by reducing the amount of space and ambient air around and within the item. In this way, the plasma generated fills only the required volume of the item to be cleaned and the plasm is directed at the object, not directed at or released into non-target areas.

A portable illumination apparatus having a sterilizing function, the illumination apparatus including: a lamp unit which includes an illuminating light element on an interior side of the lamp unit; a base coupled to the lamp unit by a hinge; and a sterilizing light element located on the interior side of the lamp unit. When the lamp unit is in a closed position with the base, the lamp unit and the base meet at a boundary section to form a cylinder with a top and a bottom. Also, the boundary section is substantially mirror-symmetrical and at least partially U-shaped such that the lamp unit has a longest height line and a shortest height line. Additionally, the illuminating light element is arranged on or along the longest height line and the hinge is formed about the shortest height line.

UV hard-surface disinfection system that is able to disinfect the hard surfaces in a room, while minimizing missed areas due to shadows by providing multiple UV light towers that can be placed in several areas of a room such that shadowed areas are eliminated and that can be transported by a cart that is low to the ground such that the towers may be loaded and unloaded easily by a single operator. The system is able to be controlled remotely, such that during activation of the system, no operator is present, and to automatically cut power to all towers in the event that a person enters the room.

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

A system for sterilizing biological material comprising beam generation circuitry for generating a radiating wave having radiating energy therein at a predetermined frequency therein. A controller controls the radiating wave generation at the predetermined frequency. The predetermined frequency equals a resonance frequency of a particular biological material and is determined responsive to a plurality of parameters from an influenza virus. The predetermined frequency induces a mechanical resonance vibration at the resonance frequency of the particular biological material within the particular biological material for destroying a capsid of the particular biological material. Radiating circuitry projects the radiating wave on a predetermined location to destroy the particular biological material at the predetermined location.

A system for pretreating and disinfecting waste, wherein the system includes a transport line configured to move the waste, and including a conveying device, a heating device configured to heat a part at least of the waste when the waste moves along a part at least of the transport line, and in that the system includes a tunnel hermetically sealing a part at least of the waste transport line, and in that the system further includes an ozone injection device configured to apply ozone on a part at least of the waste when the waste moves along a part at least of the transport line.
