Problems solved by technology

However, due to the breathing of the wearer, fog is easily generated on the traditional transparent medical protective mask, resulting in a decrease in vision clarity, which will affect the normal work of medical staff and is not conducive to the use of medical staff.
In addition, traditional medical protective masks are usually fixed by elastic belts, and the length is inconvenient to adjust. Too loose elastic belts cannot be stored and fixed, and too tight will increase the discomfort of the wearer.

Abstract

The invention discloses an anti-fog medical protective mask, which comprises an arc-shaped transparent face screen, a support pad arranged on the arc-shaped transparent face screen, a left adhesive tape and a right adhesive tape; the left adhesive tape is provided with an adhesive buckle, the right adhesive tape is provided with an adhesive female button that can be pasted with the adhesive sub-button; the surface of the curved transparent screen is provided with a hydrophilic anti-fog coating, and the hydrophilic anti-fog coating is coated with It is obtained after being covered with a hydrophilic anti-fog coating and then dried. The anti-fog medical protective mask of the present invention is mainly used to block pollutants with infection risks such as droplets, blood, body fluids, secretions, etc. for the wearer, and is fixed by setting the left adhesive tape and the right adhesive tape, which can conveniently adjust the tightness; By setting a hydrophilic anti-fog coating on the surface of the curved transparent face screen, the curved transparent face screen has excellent anti-fog performance and high light transmittance, which can ensure that the medical staff wearing protective masks have a clear view without affecting The operation of medical staff has a good market application prospect.

Description

technical field [0001] The invention relates to the field of protective equipment, in particular to an anti-fog medical protective mask. Background technique [0002] When medical staff perform surgery or clean medical equipment or deal with patients with infection risks or related operations, in order to prevent cleaning fluid, droplets, blood, body fluids, secretions and other pollutants from splashing on the face of medical staff, they usually need to wear transparent face shields to protect healthcare workers. However, due to the wearer's breathing, fog is easily generated on the traditional transparent medical protective mask, resulting in a decrease in vision clarity, which will affect the normal work of medical staff and is not conducive to the use of medical staff. In addition, traditional medical protective masks are usually fixed by elastic belts, and the length is inconvenient to adjust. Too loose elastic belts cannot be kept and fixed, and too tight will increas...
