Abstract: In a contaminated environment with health threatening aerosol a helmet with transparent face shield as an alternative to mask can be used. The helmet protects the entire head of a person using a transparent shield that is knotted at the back of the neck. The helmet uses a fan to suck the environment air, filter it with an aerosol filter and releases the clean air into the interior of the helmet. The contaminated air inside the helmet is filtered and then the clean air is sucked by another fan and released to the environment. The fans are battery powered and their speed can be controlled using sensors and a controller.

Abstract: An alternative device to a mask that blocks a patient's aerosol and avoids contamination of the patient's surrounding environment is described. The device has a flexible arm that holds an aerosol disposal pipe with one side connected to a wall, a bed, or pole attached to a floor. The second side of the flexible arm is attached to a circular or elliptical pipe that covers the face of the patient. The elliptical or circular pipe comprises of two independent moving and rotating halves to create two aerosol sucking planes. The sucking function is provided by sucking fans attached to the two halves of the circular or elliptical pipes or by a remote pump. The sucked aerosol may be filtered and released to the environment or guided to a sink P-Trap or an inlet of sewer.

Abstract: Hygiene regulations and social distancing are very effective in blocking short distance infections. During the lockdown, the distance rules can usually be adhered to, but what happens when the actual lockdown is over, and the people meet again in a confined space? Then additional effective and efficient protection is essential to stabilize infection rates. Since the viruses are spread by contact and droplet infection, technical devices are required that effectively intervene in the chain of infection and effectively block infection. An effective protection is the respiratory mask as known since 100 years. This patent application discloses an alternative to mask that is an aerosol protection helmet (APH) for various applications in the environment. The aerosol protection helmet consists of adjustable air sucking and blowing devices in different form factors based on the application. The aerosol protection helmet protects against any aerosol in the environment.

The protection system consists of adjustable air sucking device and air blowing device in different form factors based on application. The aerosol protection system uses either an air curtain or air shield to prevent the aerosol going from one side of the curtain or shield to the other side.
