Patent Application
20210346631
This invention relates to medical apparatus and instruments, and in particular, it relates to a protective helmet system, such as an antivirus helmet system.
There is no doubt that there are many ways infectious diseases can spread. Accordingly, various preventions should be taken to cope with a specific mode of transmission. For a pandemic, such as Covid-19, the infection form are still not exactly known. However, one known way that the coronavirus spreads is through normal breathing of infected humans. It has been proven that the coronavirus floats in air for quite a long time. As patients are treated in hospitals, it is inevitable that medical staff will be in close contact with patients. At the present, the common way to protect doctors and nurses from being infected is for them to wear face masks and safety goggles. In spite of this protective gear, a proportion of the medical staff may catch the virus. Traditional masks and goggles can only provide a limited degree of protection. There is no perfect way to completely avoid being infected with the virus. In addition, wearing a mask makes the user feel suffocated.
To address this problem, a protective helmet, such as an antivirus helmet including a helmet and a backpack is provided to protect medical staff from the virus spread by breathing the air in the place where they work. A healthy air supply, free from the virus, is stored in the air reservoir, and flows into a helmet for medical staff to breathe freely during their contact with patients. The antivirus helmet is a much safer protective device than face masks and goggles.
The antivirus helmet system according to embodiments of the present invention includes an airtight helmet, air and electricity supply system. The helmet encloses the user's head and is airtight except for an inlet and outlet. The helmet has an observation window made of sandwich glass or other transparent materials. Some heater wires are embedded in the sandwich glass; electricity is supplied by an external battery. The air that the user breathes is provided by an external air reservoir. The high pressure air free from virus is depressurized and cooled a bit before entering the helmet. To prevent the virus from entering the helmet against the exhaling current, the user's exhaled gas passes through a breathing valve and a water tank before being discharged into the ward. The air reservoir, battery, refrigerator and water tank are all placed in a backpack carried by the user. Such an antivirus helmet can provide a safe and comfortable breathing environment for medical staff working in a virus ward.
Additional features and advantages of the invention will be set forth in the descriptions that follow and in part will be apparent from the description, or may be learned by practice of the invention. The objectives and other advantages of the invention will be realized and attained by the structure particularly pointed out in the written description and claims thereof as well as the appended drawings.
To achieve the above objects, the present invention provides a protective helmet system which includes: a helmet, including a rigid enclosure with a transparent viewing window, and a retaining ring joined to the enclosure in an airtight connection, wherein the transparent viewing window includes multiple layers of transparent materials with embedded heater wire, and wherein the enclosure an air inlet hole and an air outlet hole in its side wall; and a backpack, wherein the backpack contains an air and electricity supply system coupled to the helmet.
In some embodiments, the rigid enclosure includes an upside-down cylindrical container and an upside-down frustum joined to the upside-down cylindrical container in an airtight connection, and wherein the retaining ring includes an elastic band.
In some embodiments, the air and electricity supply system includes: an air reservoir with an pressure reducing valve, configured to storing high pressure air; an air cooler; and a battery; wherein the air reservoir is connected to the air cooler, and the air cooler is connected to the air inlet hole of the helmet by a first tube, and wherein the battery is electrically coupled to the air cooler and the heater wire of the helmet.
It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory and are intended to provide further explanation of the invention as claimed.
It will be apparent to those skilled in the art that various modifications and variations can be made in the helmet system of the present invention without departing from the spirit or scope of the invention. Thus, it is intended that the present invention cover modifications and variations that come within the scope of the appended claims and their equivalents.
