[0025] See also Figure 1 The utility model provides an oxygen mask, which includes a mask body, a overlapped seam is arranged on the mask body, two sides of the overlapped seam are connected by a fixing piece, a flexible connection structure 10 is arranged at the bottom of the overlapped seam, and when the fixing piece is in a connected state, the flexible connection structure 10 forms a perforation.

[0026] In the present invention, the overlapping seam can be one or two. Taking two overlapping seams as an example, for the convenience of subsequent description, the two overlapping seams are respectively referred to as the first overlapping seam 1 and the second overlapping seam 2. The first overlapping seam 1 and the second overlapping seam 2 are symmetrically distributed with respect to the central axis of the mask body, and the first overlapping seam 1 and the second overlapping seam 2 divide the mask body into the first cover body 11 and the second cover body 12. The bottoms of the first cover body 11 and the second cover body 12 are still connected to each other, that is, the first overlapping seam 1 and the second overlapping seam 2 do not completely separate the first cover body 11 and the second cover body 12. The mask body is made of a soft material, so that the first cover body 11 can be bent to fit the second cover body 12, that is, the first cover body 11 can move toward the second cover body 12 to close the first overlapping seam 1 and / or the second overlapping seam 2. A flexible connection structure 10 is provided at the bottom of the first overlapped seam 1 and the second overlapped seam 2. The flexible connection structure 10 at the bottom of the first overlapped seam 1 encloses the first perforation 3, and the flexible connection structure 10 at the bottom of the second overlapped seam 2 encloses the second perforation 4. The ends of the first overlapped seam 1 and the second overlapped seam 2 are fixedly connected with the flexible connection structure 10. With the connection of the first overlapped seam 1 and the second overlapped seam 2, the flexible connection structure 10 can enclose the first perforation 3 and the second perforation 4. The flexible connection structure 10 is preferably a lining cloth or soft silicone.

[0027] When the first overlapping seam 1 and the second overlapping seam 2 are closed, the first cover body 11 and the second cover body 12 can be fixedly connected by a fixing member. The fixing member includes a hook surface 9 and a velvet surface 8, wherein the hook surface 9 is fixed on the second cover body 12, and the velvet surface 8 is fixed on the first cover body 11, and the hook surface 9 is arranged opposite to the velvet surface 8. When the first overlapping seam 1 and / or the second overlapping seam 2 are closed, the velvet surface 8 fits the hook surface 9. When the patient uses the oxygen mask, the velvet surface 8 can be set to face the face and the hook surface 9 can be set to face away from the face to avoid the surface structure of the hook surface 9 causing damage to the facial skin during use, affecting the user experience.

[0028] Taking the insertion of a nasogastric tube during oxygen inhalation as an example, the nasogastric tube can be inserted through the first perforation 3 or the second perforation 4. Taking the insertion of a nasogastric tube through the first perforation 3 as an example, specifically, when the first perforation 3 is needed, the second overlap seam 2 is first closed, and when closing, the edges of the first cover body 11 and the second cover body 12 on the other side can be overlapped with each other until the second perforation 4 becomes smaller, until the second perforation 4 disappears, and then the nasogastric tube is inserted into the first perforation 3, and the first overlap seam 1 is closed after the nasogastric tube is inserted into the first perforation 3, and the nasogastric tube passes through the first perforation 3. The flexible connection structure 10 is abutted against the outer peripheral surface of the nasogastric tube to make up for the gap of the nasogastric tube and improve the sealing. It can be seen that while the oxygen mask supplies oxygen, the nasogastric tube can also provide nutrition, and the nasogastric tube does not need to pass between the oxygen mask and the face, which is more comfortable to wear. Nasogastric feeding and oxygen inhalation can be carried out simultaneously, ensuring that the patient's basic vital signs are stable while also ensuring the supply of nutrition and oxygen.

[0029] The center distance between the first perforation 3 and the second perforation 4 is 1-3cm, so that it can be closer to the user's nostril position and is more convenient to use. Preferably, the center distance between the first perforation 3 and the second perforation 4 is 1.5cm, so that the first perforation 3 and the second perforation 4 are as close to the position of the nostril as possible, reducing the possibility of bending of the pipeline such as the nasogastric tube. At the same time, the aperture of the first perforation 3 and the second perforation 4 is 4-8cm, and preferably, the aperture of the first perforation 3 and the second perforation 4 is 6mm to ensure that the nasogastric tube can pass smoothly. The distance between the first perforation 3 and the edge of the first cover body 11 is 2-6cm, and the distance between the second perforation 4 and the edge of the first cover body 11 is 2-6cm. More preferably, the first perforation 3 and the second perforation 4 are 4cm away from the edge of the mask body to adapt to the face shape of most users. Reduce the possibility of bending of pipelines such as nasogastric tubes.

[0030] The shaping strip 5 is fixed to the end surface of the first mask body 11 that contacts the face. The shaping strip 5 is arranged to fit the edge of the first mask body 11. After wearing, the shaping strip 5 contacts the bridge of the nose. By pressing the shaping strip 5, the first mask body 11 can fit the direction of the bridge of the nose, thereby improving the sealing of the first mask body 11 and making the first mask body 11 fit the face better.

[0031] The second mask body 12 is provided with a vent hole 6 so that the oxygen mask can normally discharge the carbon dioxide in the oxygen mask after being worn. The edge of the second mask body 12 is fixed with a strap 7, which is symmetrically arranged with the central axis of the mask body as the symmetry axis. The width of the strap 7 can be 0.5 cm-1 cm or wider. The mask body can be fixed by the strap 7 when worn. At the same time, the contact surface between the strap 7 and the facial skin is wider, which makes it more comfortable to wear and reduces the possibility of pressure sores.

[0032] The oxygen mask provided by the utility model is provided with a first perforation 3 and a second perforation 4 on the mask body, and the relative position is just at the outlet of the nasogastric tube. The first perforation 3 and the second perforation 4 are used as starting points to form a first overlap seam 1 and a second overlap seam 2 at the edge of the mask body, and the mask body is divided into a first cover body 11 and a second cover body 12. The first cover body 11 and the second cover body 12 are bonded to each other through a velvet surface 8 and a hook surface 9 to ensure the airtightness of the mask body. When in use, the hook surface 9 is preferably set to face away from the face to reduce the damage caused by the hook surface 9 to the facial skin. During use, in addition to being able to meet the oxygen supply demand, it is also possible to use a nasopharyngeal ventilation tube or a nasogastric tube through the first perforation 3 or the second perforation 4 during oxygen supply, reduce the occurrence of facial pressure sores, meet the patient's comfort requirements, facilitate the patient's oxygen inhalation and nasogastric feeding at the same time, facilitate the patient's oxygen supply and sufficient nutrition intake, and have a good use effect.
