Abstract
The device is to innovate a face mask with 3 stages:- (First Stage) it is the primary filtration stage to prevent dust and fine sand from passing to the next stage of disinfectant and reduce the amount of microorganisms transported on the dust surface also to create a clean and clear environment inside the sterilizing tube to make the disinfecting sterilizing lamp work effectively without collecting any dust on its surface. (Second Stage) it is the disinfectant stage throw expose the air entering from the first stage to a (Ultraviolet Sterilizing lamp radiation Preferred UV-C). The Ultraviolet lamp is fixed inside a portable cylinder tube with reflected surface from inside to ensure maximum exposer of the airborne bacteria and viruses to enough amount of radiation from the sterilizing UV- lamp that is used to break down the DNA and the RNA of the bacteria and virus cells to kill the bacteria and viruses. (Third Stage) it is the final fine filtration (N95 filter is preferred) to prevent the resulted viruses and bacteria cells after disinfection resulting from the second stage to enter the respiratory system also it is used to decrease and regulate the rate of respiration to give enough retention time to the sterilizing lamp to complete disinfect and kill maximum amount of airborne viruses and bacteria. This innovated mask is mainly for users that highly exposed to airborne viruses and bacteria in hospitals, labs also can be used by public if needed and for patients by reversing the system to decrease and kill viruses result from there respiration to the environment.
Description
Disinfectant viral and Bacterial Portable Mask
Technical Field:
Medical engineering, Environmental engineering and infection control.
Background Art:
The previous art is to use a filter in the face masks to reduce the amount of pathogenic viruses and air bacteria to help in reducing the chance of infection.
The previous art depend on filter porosity to screen airborne viruses and bacteria without killing these pathogens only depend percentage of living pathogens on the outer surface of the filter, that’s make the previous art rule only reduce the percentage of microbes passing through the filter mask without affecting the survival ability of the pathogenic viruses or bacteria.
The Problem or deficiencies in the previous art:
The filter used in the traditional Face Mask is to reduce the amount of viruses that can enter the respiratory system, but there is a percentage of these pathogenic viruses and bacteria can pass through the filter to the respiratory system, and also also the filter becomes contaminated because it contains living viruses and bacteria on its outer surface.
Masks with all kinds of filter do not eliminate, weaken or kill the pathogenic bacteria or virus that infects the respiratory system, but its role only to reduce the percentage of microbes passing through the filter mask without affecting the survival ability of the pathogenic viruses or bacteria.
Disclosure of Invention:
The mask is used the same way as the traditional mask (figure l(No.5)) but with the addition of a sterilization cylinder (figure l(No.2)) (to kill bacteria and viruses) between the initial filter used to screen the dust (figure l(No.l)) and the final fine filter (figure l(No.4)) to prevent the largest possible percentage of the remaining cells of the viruses and bacteria from entering the respiratory system.
The sterilization cylinder (figure l(No.2)) works by passing the air to be exposed to the Sterilizing Ultraviolet radiation. The sterilization cylinder length and the bulb intensity also vary depending on the type of virus or bacteria targeted as each type of bacteria or virus required different retention time to get the amount of radiation required to breaking the DNA and RNA of the viruses and bacteria targeted.
A battery (figure 1 (No.3)) needed to operate the sterilization bulb are installed as shown in drawing direct to the mask or on a belt to give freedom to use hands at work.
Sterilization UV lamp (figure l(No.2)) works inside must be in a reflective cylinder from the inside to ensure distribution and expose the microbes to a sufficient amount of radiation capable of getting rid of these microbes and also to protect the user from exposure to this radiation.
At the last stage, a microfiltration filter (figure l(No. 4)) is installed to screen the remaining microbes after sterilization to reduce or prevent the access to the respiratory system also to regulate respiration rate to give enough retention time for disinfection.
The device is designed to be used directly attached to the face mask as in figure 1 or using a flexible tube to link between desalination stage and fine filtration stage as shown in (figure 2(No.6)).
This device is designed to be used by those dealing directly with viruses and bacteria from doctors, pharmacists, scientists, laboratories, and the public in case of need, as well as patients by inversing the system to sterilize and disinfect and kill the microbes emerging through exhalation.
Brief Description Of the drawings 1 and 2:
1- Dust and fine sand filter
2- disinfection unit including sterilizing Ultraviolet lamp
3- Battery and inverter to operate the ultraviolet lamp
4- Fine Filter to prevent respiring the rest of the virus or bacteria fell after disinfection using the UV lamb also for disinfecting the Filter and its is preferred to use N95 filter to regulate respiration rate to give enough time for complete disinfection.
5- full or half mask
6- flexible tube to link between desalination stage and fine filtration stage
Claims
Claims:
