16Devices for influencing the respiratory system of patients by gas treatment, e.g. mouth-to-mouth respiration; Tracheal tubes
Appl.No 15471882 Applicant Mohamed A Basiony Inventor Mohamed A Basiony

A present idea relates to a device to kill micro-organisms inside the patient's respiratory tract using UV light, specifically UV-C. It is particularly used to treat patients with Coronaviruses family such as Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS). The device consists of a triple-lumen catheter and UV control unit. The distal end of one of the catheter's lumen has a curved UV chamber while the proximal end has a cable with a socket to be connected to the UV control unit. The second lumen of the catheter is used for oxygen supply, and the third lumen of the catheter is used for suction.

The invention provides a device used for blocking infecting of diseases such as novel coronavirus spread by droplets. The device comprises a chemical sterilization and disinfection unit, a physical sterilization and disinfection device, an air filter, a hood and other auxiliary unit. Different combinations of the units of the device can achieve two work states, the positive-pressure work state andthe negative-pressure work state. When the device is in the positive-pressure work state, the hood is full of sterilized and disinfected air, the pressure is higher than environment pressure, and thedevice is suitable for healthy personnel working in environments where people are likely to be infected. When the device is in the negative-pressure state, the internal pressure of the hood is lowerthan the environment pressure, air exhaled by users is exhausted into the environment after being sterilized and disinfected, and the device is suitable for being used by suspected infected patients or diagnosed infectious victims. According to the device capable of reducing the concentrations of bacterial viruses in the local environment through direct sterilization and disinfection, bacterial viruses are eliminated from the source and are killed before being diffused, healthy personnel who have to work in the environment are protected, and the patient recovery process is promoted.
