Abstract

The utility model relates to an oxygen mask which comprises a mask that covers the mouth and nose of human, an oxygen delivery connector that is connected on the mask and a head belt that is fixed on the mask. Vent holes are arranged on the two left and right external sides of the mask body of the mask. Membranes that can open or close the vent holes according to the close and open of air stream are installed at the offside of the vent holes. The oxygen supplying hole of the oxygen delivery connector is provided with a membrane that can perform axial movement along the air stream. The membrane movements of in the oxygen supplying hole in the vent hole and the oxygen connector can be controlled by the movement of the air stream. The structure is simple, the use is convenient. The utility model also solves the problem of oxygen waste and can increase the utilization rate of oxygen uptaking. The utility model can be applied in wards in hospitals, high pressure oxygen cabin, first air center, sanitariums, plateau sections, oxygen bars, planes and trains.

Description

Oxygen absorption mask

Technical field

This utility model relates to a kind of oxygen absorption mask, especially relates to a kind of efficient oxygen absorption mask.

Background technology

Present disclosed oxygen absorption mask is by transparent cover, is arranged on that the transparent face mask both sides are positioned at the breeder tube at mouth and nose place and the oxygen therapy joint on the transparent cover constitutes, pure oxygen is supplied with oxygen therapic patient through conduit by the oxygen therapy joint, oxygen therapic patient then by oxygen therapy joint oxygen intake from oxygen cylinder, then discharge from the breeder tube of face shield by the carbon dioxide that oxygen therapic patient is breathed out.But in oxygen therapic patient oxygen uptake or exhaust process, because of making the air-flow inside and outside the face shield, breeder tube communicates, so when the oxygen therapic patient oxygen intake, just having the part air enters in the face shield by breeder tube, and oxygen therapic patient is when giving off carbon dioxide, and can produce the part carbon dioxide again carries out in the oxygen catheter from the oxygen therapy joint, influences the oxygen uptake effect, cause the oxygen uptake rate to descend, and also cause the waste of oxygen.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of simple in structure, the oxygen absorption mask that the oxygen uptake rate is high.

This utility model is that the technical scheme that achieves the above object is: a kind of oxygen absorption mask, comprise the face shield that is fastened on the human nasal mouth, be connected the oxygen therapy joint on the face shield and be fixed on headband on the face shield, face shield is positioned at that two outsides are provided with breeder tube about cover body, it is characterized in that: the diaphragm that can close or open breeder tube with air-flow also is equipped with in the breeder tube outside of face shield cover body both sides, and is equipped with and can makes axially movable diaphragm with air-flow in the oxygen supply hole of oxygen therapy joint.

This utility model adopts the advantage after the technique scheme to be: this utility model is equipped with along the axially movable diaphragm of aperture at the breeder tube place of face shield both sides, can control diaphragm opening and closing passage by the motion of air-flow, in the oxygen therapy joint, also be equipped with equally by air motion control diaphragm opening and closing oxygen supply hole, easy to use, and solved the problem of waste of oxygen, can improve the oxygen uptake rate effectively.Secondly this utility model only increases diaphragm in the breeder tube outside and oxygen supply hole, and structure is very simple, and is safe and reliable.

The specific embodiment

Oxygen absorption mask as shown in Figure 1, 2, comprise face shield 1, oxygen therapy joint 4 and headband 3, the flaring of face shield 1 is the symmetric space curve, and with the face curves at human body mouth and nose place, face shield 1 can adopt colored or transparent, be connected with oxygen therapy joint 4 and the headband 3 that is fixed on the face shield 1 on the face shield 1, the connecting hole on oxygen therapy joint 4 and the face shield 1 is interference fit.Face shield 1 is positioned at the cover body left and right sides and is provided with breeder tube 5, the diaphragm 2 that can close or open breeder tube 5 also is equipped with in the outside of the breeder tube 5 of cover body both sides, see shown in Figure 4, diaphragm 2 has mandrel 2-1 and is inserted in the connecting hole of face shield 1, and the inboard of mandrel 2-1 is provided with axial limiting catch 2-2 to prevent coming off of diaphragm 2.Also be provided with and make axially movable diaphragm 6 with air-flow in the oxygen supply hole 4-1 in oxygen therapy joint 4, this diaphragm 6 as shown in Figure 2, be installed on the supporting slice 7 of the band ventilation in the 4-1 of oxygen supply hole, the structure of diaphragm 6 is identical with the structure of diaphragm 2, the catch 6-2 that also has axial limiting, its mandrel 6-1 is inserted in the centre bore of supporting slice 7.Diaphragm 6 also can be as shown in Figure 3, be inserted in the joint aperture of 4-1 bottom, oxygen supply hole, and be provided with spacing inner convex platform 4-2 in the 4-1 hole, oxygen supply hole of oxygen therapy joint 4, when diaphragm 6 moves axially control oxygen break-make under the effect of air-flow, in case cause coming off of diaphragm 6.

When the oxygen therapic patient oxygen intake, breeder tube 5 is closed in the both sides of diaphragm 2 applying face shield 1 under the air-flow effect in the face shield 1 both sides outsides, and simultaneously, diaphragm in the oxygen therapy joint 46 is opened with air-flow, and oxygen is all sucked by oxygen therapic patient.When oxygen therapic patient gave off carbon dioxide gas, air-flow was pushed down the diaphragm 6 in the 4-1 of oxygen supply hole, and simultaneously, the diaphragm of face shield 1 both sides 2 moves outward with air-flow, opens breeder tube 5, discharges carbon dioxide, finishes exhaust work.

Oxygen absorption mask of the present utility model is widely used in hospital ward, hyperbaric oxygen chamber, emergency center, sanatorium, highlands, oxygen bar, aviation, train etc.
