Replaceable forehead pad for positive pressure breathing mask

Abstract

The invention discloses a replaceable forehead pad for a positive pressure breathing mask. The replaceable forehead pad comprises a substrate part, a support part and a buckling body; the substrate part is provided with two contact sheet bodies and a connection arm which is used for connecting two contact sheet bodies; the support part is provided with two support bodies and a plate arm which is connected with the two support bodies; a hollow area is formed among the support bodies, the plate arm and the contact sheet bodies and a hollow hole is formed on each support body to ensure that the support bodies can be flexibly compressed to be deformed; the buckling body is extended from the surfaces of two support bodies and the plate arm, and the long side of the buckling body is longer than the long side of the formed hollow area; the buckling body is provided with buckling parts; the buckling parts, and buckled parts of a mask device of the positive pressure breathing mask can be buckled and assembled; therefore, the replaceable forehead pad can be buckled conveniently and reduce the falling risk, and structural intensity and stress dispersing can be enhanced so as to reduce stress discomfort.

Description

technical field [0001] The invention relates to a breathing mask, in particular to a replaceable forehead pad structure design of a breathing mask of a positive pressure respirator. Background technique [0002] Sleep apnea (obstructive sleep apnea syndrome) is when a person sleeps, the upper airway (including nasopharynx, oropharynx, and larynx) collapses repeatedly, thus blocking the airway and causing breathing to become shallow and laborious. It can cause complete blockage of the airway, resulting in inability to breathe air and suffocation. One of the most effective ways to treat sleep apnea at present is to use continuous positive airway pressure (CPAP), which is to make the patient wear a breathing mask connected to a pump during sleep, and the pump With the help of a host control with adjustable airflow pressure, it is used to continuously inject air into the airway to generate a continuous airflow of positive pressure (positive pressure), so as to keep the patient'...

AI Technical Summary

Problems solved by technology

In actual use, the fastening portion with a slope structure is used to fasten to the mask device, which has poor structural strength and is not easy to fasten; and, the base part is a continuous sheet, and the contact part is two independent structures. The compressed stress is not easy to disperse during use, and it is easy to feel uncomfortable
