Abstract
The mouth closure for providing artificial respiration to patients consists of a deformable elliptical plate (2), whose periphery is surrounded by a tube (1). The tube is formed in the shape of an air hose made of an elastic film with a hose (3) for admission of air. A tube (4) passes through the plate (2) in a central region. The mouth closure is placed in the dentilabial cavity of the patient's upper and lower jaws. The tube, in association with the gums and the lips and cheeks, seals the oral cavity from the outside. A flow of air through the tube therefore enters the respiratory passages of the patient and also passes back from the respiratory passages, through the tube, to the outside.
Claims14
Device for providing artificial respiration to patients, having a mouth closure comprising a disk means with a soft elastic edge beading and with a tube for passing gas therethrough characterized by the fact that the disk means is a flat and elastically deformable plate with an edge beading of a soft foam plastic arranged on both sides of the plate and shaped to fit in a gas-tight manner, into the dentolabial cavity of the patient to seal the oral cavity, and that the tube for passing gas projects outward from one side of, and is attached at the middle of, the plate.
