Leech bionic ventilation mask

Abstract

The invention discloses a leech bionic ventilation mask. The leech bionic ventilation mask comprises a connector used for being connected with a breathing pipe, a ventilation mask body and a leech bionic cushion used for being in sealing contact with the portions, on the periphery of the mouth and the periphery of the nose of the human body, of the face skin during ventilation. The leech bionic cushion comprises an approximately-annular base body basically attached to the portions, on the periphery of the mouth and the periphery of the nose of the human body, of the face skin in shape and an approximately-annular suction cup face arranged on the surface layer of the lower portion of the base body and used for being in close contact with the portions, on the periphery of the mouth and the periphery of the nose of the human body, of the face skin. According to the leech bionic ventilation mask, the base body provided with the approximately-annular suction cup face is sucked to the portions, on the periphery of the mouth and the periphery of the nose, of the face skin through the continuous negative pressure, and the quite good sealing performance can be provided during ventilation. When the leech bionic ventilation mask conducts mechanical ventilation, the sealing performance is good, air leakage and wrong sucking can be avoided thoroughly, and the leech bionic ventilation mask is safe and reliable.

Description

technical field [0001] The invention relates to a ventilation mask, in particular to a leech bionic ventilation mask, which belongs to the technical field of medical devices. Background technique [0002] The anesthesia mask is a ventilation tool for non-invasive breathing support. During non-invasive breathing, the mask isolates the patient's airway from the outside world and provides breathing support for the patient. [0003] At present, the principle of the mask to isolate the patient's respiratory tract from the outside world is compression isolation. During non-invasive respiratory support, the ring-like soft gasket or air bag of the mask is tightly pressed around the patient's mouth and nose with a belt. Long-term compression may cause the patient's face Insufficient blood supply, and it is easy to cause air leakage due to mask displacement, resulting in failure of respiratory support, leading to accidents. [0004] For short-term respiratory support during anesthesi...

AI Technical Summary

Problems solved by technology

When an obese patient is encountered, the anesthesiologist is extremely laborious during ventilation, and the short-term assisted ventilation will sweat profusely, requiring replacement operations; the isolation effect of the anesthesia mask during ventilation is poor, and once the air leaks, the risk of anesthesia-induced ventilation is significantly increased, and even caused Failure of ventilation puts the patient at greater risk
