Description

Multifunctional oxygen breathing mask

Technical field

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a respiratory mask, and more particularly to a multi-functional oxygen breathing mask made of a plastic material TPE in contact with a facial skin.

Background technique

Respiratory masks are widely used in medical, life production, monitoring and sports. In the application of breathing masks, the breathing mask filters out dust and other pollutants in the air to make the user healthier and more comfortable to breathe. In addition, medically, Patients often need a sterile environment to avoid infection, and often the patient's immune system is destroyed to make the patient more susceptible to infection, so the isolation of bacteria and pollutants is very important; in addition, patients often carry some bacterial pathogens, breathing masks It can filter the gas that the patient calls into the air to prevent the patient from bringing the pathogen into the air. In addition, in the medical convenience, the respiratory mask is also used to help patients with oxygen and gas anesthesia. However, in practical applications, the mask for filtering dust and air pollutants is used separately from the medical mask, and the part of the medical mask that is in contact with the patient's face is complicated in structure and costly, so that the patient bears a high cost and is inconvenient to produce and promote. application.

Summary of the invention

The present invention is directed to the deficiencies of the prior art, and aims to provide a multi-functional oxygen breathing mask that can be used for breathing or medical treatment and has a simple structure and low cost.

The present invention is achieved by the following technical solutions: A multifunctional oxygen breathing mask comprising: a mask body having a chamber formed on the mask body; and a connecting tube pivotally connected to the mask body Up and facing one of the chambers relative to the mask body a side extension, the chamber has a through hole connected to the connecting tube; the chamber formed on the mask body is provided with a ring of elastic material at the edge of the chamber; the sealing ring is integrally molded with the chamber forming.

The above technical solutions are further elaborated below:

The connecting pipe is a "Π"-shaped connecting pipe whose vertical portion is connected with the receiving chamber and forms a pivoting end; the lateral portion is connected with an intake pipe.

The pivoting end is formed by forming two protruding annular pads on the outside of the end of the vertical portion of the connecting pipe, and the annular pad near the end of the inflection of the "Π"-shaped connecting pipe is placed outside the cavity, away from the "Π" shape. The annular pad at one end of the indentation portion of the connecting tube is placed inside the chamber, and the through hole edge of the chamber is sandwiched between the two annular pads to connect the connecting tube to the chamber; the lateral portion of the "Π" connecting tube is The groove of the inlet pipe is recessed to form a groove ring, and one end of the inlet pipe and the connecting pipe are integrally convexly formed to form a convex ring, and the concave groove ring of the connecting pipe and the convex convex of the inlet pipe The looping rings are engaged with each other to connect the intake pipe to the connecting pipe.

The "," shaped connecting pipe is provided with a venting cover at the back of the inflection portion, and a plurality of venting holes are provided in the venting cover.

The two layers of the protruding annular pad at the end of the vertical portion of the connecting tube are evenly distributed on the annular pad near one end of the inflection portion.

The chamber on the mask body is made of pp plastic material; the sealing ring is made of TPE plastic material.

The invention has the following beneficial effects: First, the sealing ring for separating the indoor air and the outside air of the face cover is a sealing ring provided at the edge of the chamber, and the sealing ring is integrally molded with the chamber, and the sealing ring is made of TPE plastic material, so The designed mask user is comfortable to wear and knots The structure is simple and the production cost is low; Secondly, the through hole edge of the chamber is sandwiched between the two annular pads to connect the connecting tube and the chamber; the concave groove ring of the connecting tube and the convex protrusion of the inlet pipe The rings are interlocked to connect the intake pipe and the connecting pipe movably. The structure thus designed is used when the patient performs oxygen delivery or in a dizzy state, and the connecting pipe can be conveniently rotated so that the air inlet can be connected to the oxygen cylinder in multiple directions. For practical application.
