Embodiment Construction

[0077] figure 1 A cross-section (in a separate window) of the central section of the mask frame is shown. Both figures show the frame 1 as translucent, consisting of an inner wall 2 and an outer wall 3 .

[0078] The mask frame has an inlet / outlet 4 (side opening) for air exchange while breathing. Cutouts 5 for nose breathing are shown on the inner wall of the frame. Located in the upper part of the frame is a nasal opening 6 for passing air exhaled through the nose to the frame cavity. The support 7 is located between the inner wall of the frame and the surface of the face. Supports are shown as closed circles. The flexible part 8 extends along the inner wall of the frame. It is made of elastic material. figure 1 An option for a flexible member in the form of an arc extending around the back of the ear is shown. figure 2 An option for a flexible part in the form of an arc extending around the back of the head is shown.

Abstract

A structured barrier-exhaust-type mask with a support relates to personal protective equipment, and specifically to masks intended primarily for use in the field of medicine. The present mask can serve as all-round environmental and hygiene protection for doctor and patient during the delivery of medical care of any degree of complexity, including long surgical procedures, and also as personal protection for civilians against airborne infection. The mask completely prevents exhaled air from passing between doctor and patient, and exhausts exhaled air in a given direction. The mask comprises ahollow structure which forms a mask cavity in the facial region and is designed in the form of a channel having an inlet and an outlet for the passage of an air flow, said mask being characterized inthat the inner and outer walls of the structure are made of an air-impermeable material, and a support is provided between the surface of the face and the inner wall of the structure, said support being in the form of an ergonomic cushion around the mouth region, or an arc running along the lower or upper jaw.

Description

technical field [0001] The claimed invention relates to personal protective equipment for humans, namely face masks mainly used in medicine. [0002] The present invention is: [0003] Provide a universal environmental and hygienic protection device for doctors and patients when performing medical assistance of any complexity, including prolonged surgical procedures; [0004] ·Provides personal protection for civilians against dust and airborne infections contained in industrial environments. [0005] In contrast to medical filtering masks, the present invention relates to masks of the barrier and venting type, ie, which completely prevent the passage of exhaled air between the doctor and the patient, and deliver the exhaled air in the intended direction. The mask is structurally presented as a hollow frame. Background technique [0006] Various options for barrier and frame mask designs are available from Background Art. [0007] From the literature (Journal "Surgical C...
