Abstract

The utility model relates to an oxygen supply mask. Soft silicon rubber at the edge of the mask is tightly combined with a face; and exhalant carbon dioxide is smoothly removed through an outward one-way valve, so that an oxygen supply amount is effectively increased. The problem of tightly contacting a carbon dioxide breathing channel and the mask with the face can be better solved.

Description

A kind of oxygen mask of giving

Technical field

This utility model is a kind of oxygen mask of giving in the technical field of medical instruments, can combine closely with face through the soft silica gel at face shield edge, through outside unidirectional flap valve the carbon dioxide of exhalation is got rid of smoothly again, has increased effective oxygen supply amount.

Background technology

The structure that at present common face shield closely is not connected with face causes face shield to combine poorly with facial, and the while exhalation vents is a style of opening, effective oxygen uptake weak effect.

The utility model content

The purpose of this utility model provides a kind of oxygen mask of giving, and realizes combining closely to oxygen mask and face, increases effective oxygen supply amount.

Its objective is such realization; At face shield and facial jointing edge soft silica gel is installed among Fig. 1, two outside unidirectional flap valves are installed in the relevant position of exhaling in the nostril, when the static line fixed visors; Soft silica gel can be well and face combine closely, increase effective oxygen supply amount.

Having solved face shield well combines closely and the smooth problem of breathing out of carbon dioxide with facial.

Description of drawings

The concrete structure of this utility model is provided by following examples and accompanying drawing:

Fig. 1, be a kind of oxygen mask side view of giving of this utility model.

Fig. 2, be that this utility model is a kind of to oxygen mask direct-view figure.

Among Fig. 1, Fig. 2,1, soft silica gel, 2, outside unidirectional flap valve, 3, the oxygen interface, 4, face shield, 5, static line.

The specific embodiment

Specify the concrete working condition that this utility model proposes below in conjunction with Fig. 1, Fig. 2; At face shield (4) and facial jointing edge soft silica gel (1) is installed among Fig. 1, Fig. 2; Two outside unidirectional flap valves (2) are installed in the relevant position of exhaling in the nostril; When static line (5) fixed visors (4), soft silica gel (1) can be well and face combine closely, increase effective oxygen supply amount.

Claims

1. give oxygen mask for one kind, form by soft silica gel, outside unidirectional flap valve, oxygen interface, face shield, static line; It is characterized in that: at face shield and facial jointing edge soft silica gel is installed, two outside unidirectional flap valves are installed in the relevant position of exhaling in the nostril.
