Description

Disposable noninvasive ventilation mask

Technical Field

The utility model relates to the technical field of ventilation masks, in particular to a disposable noninvasive ventilation mask.

Background

Critically ill patients who cannot breathe spontaneously often need an indwelling gastric tube through which a fluid food is injected into the patient's stomach with a syringe to supplement the nutritional ingredients required in the patient's body.

The serious patients who cannot breathe spontaneously often need a breathing machine to assist in breathing support, the breathing machine is often communicated with a noninvasive ventilation mask through a hose, and the noninvasive ventilation mask is used for carrying out breathing support treatment on the patients, but the noninvasive ventilation mask compresses the faces of the patients, moisture in the noninvasive ventilation mask is caused by adding water vapor exhaled by the patients, and the problems of skin surface pressure sores such as reddening, blisters or crumbling are easy to occur due to long-time facial compression.

Part of patients needing to be left with the gastric tube, because the gastric tube needs to pass through between the noninvasive ventilation mask and the facial skin, the passing position of the gastric tube can also be provided with an indentation, and the conditions of the noninvasive ventilation mask such as sealing inaccuracy, air leakage and the like are often caused.

In addition, the existing noninvasive ventilation mask bandage often can tie the neck, so that the skin of the neck of a patient is easily damaged, skin infection can be caused under severe conditions, and the recovery of the patient is not facilitated. The current common noninvasive ventilation mask generally only supports a single wearing mode, and cannot be selected in a diversified manner according to the needs of patients.

The facial contours of different patients are different, the existing noninvasive ventilation mask cannot be adjusted according to the facial contours of the patients, so that the noninvasive ventilation mask is completely attached to the facial skin, the risk of pressure sore occurrence is increased, and the probability of air leakage is increased. Accordingly, it would be a problem to be addressed by those skilled in the art to provide a disposable noninvasive ventilation mask that increases tightness and reduces pressure sores, selects different straps according to the needs of the patient, and has gastric tube access holes left.
