A face mask, also called a face guard, is usually worn by medical professionals for various purposes. It is designed to keep bacteria from infecting health care workers and patients by trapping bacteria from the mouth and nose of the wearer and capturing droplets of fluid droppings and secretions from the patient’s mouth. However, there are some cases where a mask can also be used to protect the patient from the environmental contamination and skin irritation that can come with various medications and medical procedures, such as those involved in chemotherapy. In such instances, the face mask might be made from other materials than polyethylene or vinyl.
Face masks come in many different shapes, sizes, styles, designs, and materials. Some face guards are disposable while others are to be used for a long time, and they may be reusable. They are available in a variety of colors, including white, yellow, black, red, blue, purple, pink, orange, brown, gray, and green. The face masks can be custom-made according to the patient’s specifications or chosen by the physician’s order.
The material used to make the face masks is determined by the type of materials required by the face mask manufacturer. A polyethylene or vinyl are used in most face masks. There are also some models that come in plastic, which makes them suitable for use in laboratories and other medical facilities. Vinyl or polyethylene is made from polymerized polyvinyl butyrate, or PVC, and is preferred because it is durable, easy to clean and relatively cheap. Plastic face shields are popular because they can be used for a long time.
Facial masks can come in a variety of designs. Some have a clear plastic covering to provide protection from exposure to bacteria and other substances that can damage the plastic, or to allow easy ventilation for patients who are breathing through a mask. Others feature a plastic covering that has small holes, or openings, or have small holes on all sides to allow for easier breathing.
The color and pattern of the mask can vary depending on the needs of the patient and the medical procedure. For example, many patients need an adhesive bandage or mask cover to help retain the elasticity of a patient’s face. An elastic bandage can be used if the plastic bandage used to cover the face is too loose to prevent air from blowing into the cavity between the teeth and nasal airway. When an elastic bandage is used as a face mask to cover, it is important to get the elastic bandage trimmed to an appropriate size prior to use to ensure proper fit. If the elastic bandage is too small, it will not fit the face properly.
Face masks come in different sizes so that they are easier to fit on patients’ faces, and also more convenient for them. There are also disposable plastic face masks that have tabs attached to the side so that the mask can be taken off easily when a patient needs it.
