Example Embodiment

[0021] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0022] The present invention provides an oxygen mask, including a mask body, the mask body is composed of three planes and has a triangular prismatic structure with an opening. When the mask body is worn, the mask body extends upward to the middle and lower nasal bones. One part, down to the front edge of the arteries on both sides of the mandible, while surrounding the mandible, the middle of the upper edge is provided with a supplementary port 1, about the tip of the nose, which is convenient for oxygen inhalation. The supplementary port 1 is provided with a first one-way valve The body allows gas to enter the inner cavity of the mask body in one direction. The two planes on the upper part are respectively provided with gas storage mechanism...

Abstract

The invention provides an oxygen mask, comprising a mask body. The mask body is of a three-edged structure having an opening and composed of three planes, the middle of an upper edge is provided with a gas supplement port, two planes above are provided with gas storage mechanisms, respectively, one side of each gas storage mechanism close to the opening is also provided with an oxygen supplement port used to connect an oxygen supplement appliance, and each gas storage mechanism comprises a gas storage shrinking film which has preset elasticity and size. The oxygen mask can provide constant oxygen concentration without local stimulus; the stimulus of catheter oxygen supply upon nasal mucosa is overcome, and unsmooth sputum discharge caused by sputum dryness may be avoided; the special gas storage mechanisms help increase the oxygen content in the inhaled gas and fully exert the action of oxygen therapy; a special exhaust chamber has a special one-way valve inside, helping discharge carbon dioxide and avoiding retention of the carbon dioxide; the mask is of a three-edged structure, the edges of the mask are inflating round tubes, and it is possible to increase the fit between the mask and a human face may be increased and reduce oxygen loss.

Description

technical field [0001] The invention relates to the field of medical equipment, and the feature relates to an oxygen mask. Background technique [0002] Medical oxygen masks are mainly used for oxygen delivery to patients in a hypoxic state. The medical oxygen face shield as prior art mainly is made up of face mask, oxygen delivery pipeline and free small cover etc. The medical oxygen mask isolates the user's oral cavity and nasal cavity from the outside world, and provides oxygen to the user through the oxygen pipeline connected with the medical oxygen mask. However, during the oxygen delivery process of the existing medical oxygen mask to the patient's exhalation and inhalation, the moisture in the patient's nose and mouth evaporates faster, which stimulates the mouth and nasal mucosa. Carbon dioxide is not easily released. Contents of the invention [0003] In order to solve the defects and deficiencies of the prior art, an embodiment of the present invention provide...
