Abstract

An anesthetic mask, related to mask areas, especially related to the anesthesia mask of which the facial skin contact parts are made of TPE plastic materials, includes a mask body which has a chamber on it and a connecting tube which pivots with the mask body and extends toward one side relative to the chamber of mask body. The chamber has a through hole connected to the connecting tube. The edge of said chamber formed on the mask body is mounted with a sealing ring made of elastic material. The sealing ring and chamber are integrated by injection molding. The advantageous effects of the invention are that the edge of chamber is mounted with the sealing ring for isolating air in chamber from air outside. The sealing ring made of TPE plastic materials and chamber are integrated by injection molding. The mask is so designed to make users comfortable to wear, and have simple structure and low production cost.

Description

Anesthesia mask

Technical field

The present invention relates to the field of face masks, and more particularly to an anesthesia mask made of plastic material TPE in contact with facial skin.

Background technique

Anesthesia masks are widely used for medical convenience, but the existing anesthesia masks are complicated in structure and high in production cost. For example, an anesthesia mask disclosed in Patent No. 200320129357.7 includes a mask body for covering a mouth and a nose of a human body, an annular airtight mask airbag at the lower end of the mask body, and a bubble capsule filled in the mask airbag, the mask airbag The spring flap is mounted on one side, and the anesthesia nozzle is arranged on the upper end of the mask body; the patent is used for sealing the mask body on the human body surface with an annular closed mask airbag at the lower end of the mask body, and the mask airbag is filled with foam particles, the mask A spring flap is mounted on one side of the airbag, and the structure is relatively complicated, and micro-leakage occurs.

Another example is an adsorption fixed anesthesia mask disclosed in Patent No. 200520124781.1. The structure for sealing the mask body on the face is a straw which is embedded in a ring structure in the wall of the mask body, the upper end of the straw and the annular suction airbag. Connected, the lower end of the straw is a bell-shaped suction cup, and a sealing film airbag is respectively disposed inside and outside the lower mouth of the mask body; a sealing film airbag is added inside and outside the bell-shaped suction cup mouth, so that the mask body is leakproof The gas performance is greatly improved; however, the structure disclosed in this patent is more complicated, and the suction of the suction cup on the human body makes the user very uncomfortable.

Summary of the invention

The present invention is directed to the deficiencies of the prior art, and aims to provide a simple structure and production cost. Low and easy to use, comfortable anesthesia mask.

The present invention is achieved by the following technical solutions: The anesthesia mask includes a mask body having a chamber formed on the mask body; and a connecting tube pivotally connected to the mask body and facing relative to the mask body One side of the chamber extends, 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; It is integrally molded with the chamber.

The above technical solutions are further elaborated below:

One end of the connecting tube is connected to the chamber and forms a pivoting end at the joint.

The pivoting end is formed by forming two protruding annular pads at the end of the connection between the connecting tube and the chamber, and the annular pad closer to the bottom end of the connecting tube is placed inside the chamber, and the annular pad is farther away from the bottom end of the connecting tube. Outside the chamber, the through hole edge of the chamber is sandwiched between the two annular pads to connect the connecting tube to the chamber.

Three hooks are evenly distributed on the annular circumference of the annular pad on the pivoting end farther from the bottom end of the connecting tube.

The chamber on the mask body is made of pp plastic material;

Made of TPE plastic material.

The utility model has the beneficial effects that: the sealing ring for separating the indoor air and the outside air of the mask 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, the mask thus designed The user is comfortable to wear, has a simple structure and low production cost.

detailed description

Referring to FIG. 1 , the anesthesia mask of the present invention includes a mask body 1 , a chamber 2 formed on the mask body 1 , and a connecting tube 3 . The connecting tube 3 is pivotally connected to the mask body 1 and faces the mask body. One side of the chamber 2 extends, the chamber 2 has a through hole connected to the connecting tube 3; a ring of elastic material 4 is arranged at the edge of the chamber 2, and the sealing ring 4 and the chamber 2 The injection molding is integrally formed, and the sealing ring 4 is made of TPE plastic material. The sealing chamber 4 seals the chamber 2 of the mask body 1 on the human body surface, has a simple structure, low production cost, and is very convenient to use.

The connecting tube 3 - end is connected with the chamber 2 and forms a pivoting end 5 at the joint; the pivoting end 5 is formed by forming a two-layer protruding annular pad at the end of the connecting tube 3 and the chamber 2, which is closer to the connecting An annular pad at one end of the bottom of the tube 3 is placed inside the chamber 2, and an annular pad farther from the bottom end of the connecting tube 3 is placed outside the chamber 2, and the through-hole edge of the chamber 2 is sandwiched between the two annular pads to connect the tube 3 with the volume The chamber 2 can be movably connected. In practical application, the connecting tube 3 can be rotated relative to the gas pipeline for inputting the anesthetic gas, which facilitates the connection of the mask body 1 with the gas pipeline, and leaves an active space for the patient.

Three hooks 6 are evenly distributed on the annular circumference of the annular pad on the pivot end 5 away from the bottom end of the connecting tube 3, and the mask body 1 is fixed to the patient's head by three hooks 6.

The above embodiments may be modified and modified as appropriate by those skilled in the art in light of the above disclosure. Therefore, the present invention is not limited to the specific embodiments disclosed and described, and the modifications and variations of the invention are intended to fall within the scope of the appended claims. In addition, although used in this manual There are some specific terms, but these terms are for convenience of description and do not constitute any limitation to the present invention.
