Detailed Description

The present invention will be further described with reference to the accompanying drawings.

Example 1:

the oxygen mask shown in fig. 1 comprises a mask body 1 and a tying belt 2 for fixing the mask body 1 on the mouth and nose parts, wherein two ends of the tying belt 2 are respectively fixed on two sides of the mask body 1, an opening 21 is arranged in the middle of the tying belt 2, a plurality of connecting belts 22 are arranged on the opening 21, and two ends of the connecting belts 22 are respectively fixed on the tying belts 2 on two sides of the opening 21.

Fix the oxygen mask of this embodiment behind patient's oronasal part, adjust the position of frenulum 2, place patient's headrest portion in the middle of the opening 21 of frenulum 2, the frenulum 2 of opening 21 both sides is located patient's top of the head and neck portion respectively, patient's head has the radian, and frenulum 2 on opening 21 both sides can effectually be fixed on patient is overhead, when patient's head takes place to move about, can not move patient's head yet and break away from, has strengthened the steadiness of face guard.

In order to adapt to patients with different head circumference and facilitate wearing of the oxygen mask in the embodiment, the strap 2 or the connecting band 22 may be made of elastic material according to requirements. The opening 21 is provided with a plurality of connecting belts 22, two ends of each connecting belt 22 are respectively connected with the tying belts 2 on two sides of the opening 21, and the connecting belts 22 arranged on the opening 21 can ensure that the head of the patient cannot pass through the opening 21 when the opening 21 is too large. And be parallel to each other and perpendicular to frenulum 2 is fixed between the different connecting bands 22, when the frenulum 2 that itself has elasticity takes place deformation, can not receive connecting band 22 to influence, can normal use.

In this embodiment, adopt the screw thread to be connected connector 4 and connector 3 on pipe 61 or the atomizer, can strengthen the connection steadiness that links, guarantee that connector 4 can not break away from connector 3 of the cover body 1 when the patient's head is in the activity.

As shown in fig. 2 and fig. 3, the connection structure of the connection port 3 and the connection head 4 on the cover 1 is schematically illustrated, and the connection port 3 and the connection head 4 are fixed to each other by a sleeve 5.
