It can be seen that "first" and "second" " is only for the convenience of expression, and should not be understood as a limitation on the embodiments of the present utility model, and the subsequent embodiments will not explain them one by one.

With reference to shown in Fig. 1, it is the front view of an embodiment of the utility model oxygen mask. The oxygen mask includes: a mask main body 1, a first adapter 2, a second adapter 3, a suction tube 4 and a feeding tube, which are not shown in the figure. The extension part 11 of the mask main body 1 is adapted to the corresponding face of the human body, and the oxygen mask can be tightly adsorbed on the facial skin during use. Both sides of the mask main body 1 have air outlet holes 12, which are used to discharge the exhaust gas exhaled by the human body in time; gas, which can avoid inhaling too much outside air and reduce the oxygen supply effect of the oxygen mask. The mask main body 1 also has a clip 5 at the position corresponding to the bridge of the nose, and the clip 5 is used to clamp the bridge of the nose so that the oxygen mask fits the face of the human body better. The first adapter 2 is fixed at the position corresponding to the nostril of the mask main body 1, and is used to connect with the external oxygen tube, and introduce the oxygen stored externally into the human body through the oxygen mask; the first adapter 2 is located in the mask The outer part of the main body 1 has at least one air intake hole 21, and the air intake hole 21 is used to inhale external air, so as to avoid oxygen poisoning of the user caused by excessive oxygen concentration in the oxygen mask. The second adapter 3 is arranged at the position corresponding to the mouth of the mask main body 1, the second adapter 3 has two connecting ends inside and outside, and the second adapter 3 is placed inside the mask main body 1. One end is connected with the suction pipe 4, and the other end is connected with the feeding tube for feeding of the patient.

It can be known from the above embodiments that the oxygen mask connects the mouth of the user in the mask with the outside through the second adapter 3, so that when the oxygen mask is in use, the user can inhale through the suction tube 4 and the feeding tube Congee, soup, porridge and water and other liquid foods greatly improve the convenience and safety of the oxygen mask.

In some optional embodiments, the second adapter 3, the straw 4 and the feeding tube are fixedly connected, that is, the straw 4 and the feeding tube are part of the second adapter 3 , forming an overall structure. This can ensure the tightness and stability of the oxygen mask. It is also possible to fix the straw 4 and the second adapter 3 as an integral structure, the outside of which is connected to the feeding tube.

In some optional embodiments, the first adapter 2 is rotatably connected to the mask main body 1 . The position of the mask main body 1 corresponding to the nostril has a columnar protrusion 14 , the first adapter 2 is engaged in the columnar protrusion 14 and the first adapter 2 can rotate relative to the columnar protrusion 14 . In this way, when the oxygen mask is connected to the external oxygen tube, the first adapter 2 can be rotated according to actual needs, so that the oxygen tube is in a proper position.

Preferably, the part where the first adapter 2 is rotatably connected to the mask main body 1 is provided with coincident slots, which are not shown in the figure. Turning the first adapter 2 can adjust the size of the coincident slot between the first adapter 2 and the mask main body 1, that is, adjust the size of the slot where the oxygen mask communicates with the outside. In this way, the user can adjust the size of the air inlet of the oxygen mask correspondingly, and then adjust the concentration of oxygen in the oxygen mask, which greatly improves the oxygen supply effect of the oxygen mask.

In some optional embodiments, as shown in FIG. 2 , the extension portion 11 of the mask main body 1 is an inflatable air bag. In this way, the extension part 11 of the mask main body 1 has better elasticity and tightness, which not only improves the utilization rate of the oxygen mask, but also makes it more comfortable for the user to wear, and greatly reduces the extrusion of the mask to the face.

Further, the inflatable air bag is filled with gas or liquid. The gas or liquid in the inflatable airbag can be set according to the use environment of the oxygen mask and the actual needs of the user. In this way, the oxygen mask becomes more humanized and has better adaptability.

Preferably, the inflatable airbag is filled with air or water. The required air or water is not only easy to replenish, but also does not cause other pollution to the outside world.

In some optional embodiments, the inflatable airbag has an inflation port 111 . The inflation port 111 is used to replenish or adjust the gas in the inflatable airbag. According to different use environments, the gas concentration in the inflatable airbag will also be different. The inflatable airbag can be inflated according to the needs of use. Or emit part of the gas, so that the oxygen mask is in the best condition.

In some optional embodiments, the extension part 11 of the mask main body 1 is provided with at least two hanging leaves 13 for connecting the elastic hanging rope 6 . The hanging leaves 13 are symmetrically arranged on both sides of the mask main body 1, and the two ends of the elastic lanyard 6 are connected to the hanging leaves 13; the elastic lanyard 6 fixes the oxygen mask on the human body. face, improving the reliability of the oxygen mask.

In some optional embodiments, the oxygen mask has two sets of elastic lanyards 6, and the two sets of elastic lanyards 6 are respectively connected to the hanging leaves 13 on both sides of the oxygen mask. A group of elastic lanyards 6 are respectively hung on the two ears. The position of the hanging leaf 13 is offset upwards relative to the position of the commonly used head-mounted connection point. In this way, the force of the oxygen mask is not only more reasonable, but also more convenient and comfortable for the user to wear.

Preferably, four hanging leaves 13 are symmetrically arranged on the extension part 11 of the mask main body 1 , and there are two hanging leaves 13 on the left and right sides respectively. One of the two hanging leaves 13 on one side is located at the position corresponding to the tip of the nose of the mask main body 1 , and the other is arranged at a position between the corresponding mouth and the chin of the mask main body 1 . In this way, both sides of the oxygen mask are connected to the ears of the human body through two connection points, which not only makes the oxygen mask have better sealing performance, but also makes it more convenient and firm to wear.

In some optional embodiments, the part where the elastic lanyard 6 is in contact with the ear is wrapped with a layer of elastic material. The elastic material is used to reduce the friction between the elastic lanyard 6 and the ear, and at the same time, the force exerted by the elastic lanyard 6 on the ear can be evenly distributed at the contact position between the ear and the elastic material, which greatly reduces the user's discomfort.

In some optional embodiments, as shown in FIG. 3 , the first adapter 2 is arranged obliquely along the nostrils, and the second adapter 3 is arranged obliquely accordingly. In this way, not only the interference between the first adapter 2 and the second adapter 3 is reduced, but also the oxygen tube and the feeding tube connected to the outside world are located in front of the face of the human body, which is convenient for the user to wear and does not Interfere with other operations.

Those of ordinary skill in the art should understand that: the discussion of any of the above embodiments is exemplary only, and is not intended to imply that the scope of the present disclosure (including claims) is limited to these examples; under the idea of the present utility model, the above embodiments Or combinations of technical features in different embodiments are also possible, and there are many other variations of the different aspects of the invention as described above, which are not provided in detail for the sake of brevity. Therefore, within the spirit and principle of the present utility model, any omission, modification, equivalent replacement, improvement, etc. should be included in the protection scope of the present utility model.
