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.

Appl.No 16921720 Applicant Tarique Jibril Rashaud Inventor Tarique Jibril Rashaud

This novel face shield/window is designed to provide all the protective qualities of traditional OSHA approved PPE face shields. Most critically, however, it also facilitates the creation of a protective Dynamic Ingress Barrier to prevent fine particles and bioaerosols from crossing the face shield plane and transport them away from the often breached and problematic periphery of mask/respirator protective zones. Integral to this process, the novel design enhances a particle's flocculant properties by disrupting the structural integrity of the corona virus electrostatic double layer, and reducing its electrokinetic potential before accelerating it into the airspace. Increasing its ability to flocculate with active viral aerosols, and subsequently settle out of the airspace for cleaning, or captive via a filter.

Appl.No 2004066342 Applicant TOMOYASU YOKO Inventor TOMOYASU YOSHIOKI

PROBLEM TO BE SOLVED: To establish a method for prevention of contracting SARS.

SOLUTION: A fabric is soaked in soap water using a surfactant for which a sterilization effect against SARS is confirmed, and the fabric is superimposed on another fabric to form a mask. The sterilization effect of the surfactant against SARS bacteria is confirmed, so that airborne infection is prevented.

Appl.No 10453722 Applicant RUSSELL JAMES K Inventor Russell James K.

A personal breathing device for filtering, diffusing, and conditioning air inhaled by a person. The device includes an eyewear frame with an attached nose piece and air-permeable membrane which is positioned to surround the nose and permit normally inhaled volumes of air to pass through the membrane as the air is inhaled, and thereby filter and condition the inhaled air. The device can be conveniently placed on and removed from the face, does not obstruct speech, and is suitable for wearing during a variety of normal daily activities to filter and condition inhaled air. The air permeable membrane can be impregnated with various liquids or other agents to enhance filtering and antimicrobial functions, or to provide cooling, moisturizing, or scenting of the inhaled air. The device can be provided with a detachable air permeable membrane which can be easily replaced as needed.

The invention relates to a protective device such as a face mask. The device protects the user from infection and may simultaneously immunise the user against future infection. The invention particularly relates to a protective device comprising a disinfection chamber wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber such that the fluid discharged from the chamber comprises inactive microorganisms, for example a device comprising a disinfection chamber in fluid communication with a face mask and wherein the chamber is arranged to disinfect and/or sterilize fluid in the chamber prior to discharge of the fluid from the chamber to the mask such that the fluid discharged from the chamber to the mask comprises inactive microorganisms. The invention also relates to a method of use of the device.
