Problems solved by technology

[0004] The present invention aims to solve the problem that the existing anesthesia masks cannot overcome the serious gas repeated inhalation caused by the continuous implementation of NPPV by ordinary anesthesia masks, and the volume of the anesthesia masks is generally 200-300ml. Accounting for about one-third of the ventilation volume, it is easy to cause carbon dioxide accumulation inside the mask, causing respiratory acidosis in patients, and an anesthesia volume-reducing mask is proposed

Abstract

The invention discloses an anesthesia volume-reducing mask, and relates to the field of medical anesthesia instruments. In order to overcome the defect that an existing anaesthetic mask cannot overcome the defect that serious repeated inhalation of gas occurs due to the fact that a common anaesthetic mask continuously implements NPPV, the volume of the anaesthetic mask is generally 200-300 ml, anairway dead space formed by the volume of the mask can occupy about one third of the ventilation capacity in the using process, carbon dioxide in the mask is easily accumulated, and a patient suffersfrom respiratory acidosis, the technical scheme is that a sealing cushion is arranged on the edge of the bottom of a mask body, a volume reduction air bag is attached to the inner surface of the maskbody, a circular through hole is formed in the lower portion of the outer surface of the mask body, an air bag inflation valve is arranged on the lower portion of the outer surface of the volume reduction air bag, the inflation end of the air bag inflation valve penetrates through the circular through hole in the outer surface of the mask body, and a mask hook is arranged in the center of the topouter surface of the mask body. The anesthesia volume-reducing mask is applicable to the field of medical anesthesia instruments.

Description

technical field [0001] The invention relates to the field of medical anesthesia equipment, in particular to an anesthesia volume reduction mask. Background technique [0002] During mechanical ventilation under general anesthesia, non-invasive positive pressure ventilation (NPPV) with a general anesthesia mask has a serious problem of gas reinhalation. Long-term mask NPPV will cause carbon dioxide accumulation in the patient's body and cause respiratory acidosis. The main reason is that the internal space volume of the anesthesia mask increases the ventilation dead space, and this part of the gas is repeatedly inhaled during mechanical ventilation. The anesthesia mask is designed according to the contour of the maxillofacial region of the human body, and all kinds of anesthesia masks have a large internal space volume. The volume of anesthesia masks commonly used by adults is generally 200-300ml, and the airway dead space formed by the volume of the mask can account for abo...
