Leech Bionic Ventilation Mask

Abstract

The invention discloses a leech bionic ventilation mask, which comprises an interface for connecting with a breathing pipeline, a cover body of the ventilation mask, and a leech bionic cushion for sealing contact with the facial skin around the mouth and nose of a human body during ventilation. The leech bionic cushion includes a ring-like base body that basically fits the shape of the facial skin around the mouth and nose of the human body and a ring-like suction cup surface arranged on the lower surface of the base body for close contact with the facial skin around the mouth and nose of the human body. , the leech bionic ventilation mask adsorbs the base body of the ring-like suction cup surface to the facial skin on the periphery of the mouth and nose through continuous negative pressure, which can provide excellent sealing performance during ventilation. The sealing performance of the present invention is good during mechanical ventilation, completely avoiding Air leakage and aspiration occur, 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 that the mask isolates the patient's airway from the outside world is compression isolation. When non-invasive breathing support is used, the ring-like soft gasket or air bag of the mask needs to be tightly compressed around the patient's mouth and nose. Long-term compression may cause the patient's face and face. Insufficient blood supply, and it is easy to cause respiratory support failure due to air leakage caused by mask displacement, resulting in accidents. [0004] For short-term breathing support during anesthesia in...

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
