[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0024] Reference Figure 1-4 , an oxygen supply mask for patients with nasogastric tubes, comprising a facial mask body 1, an oxygen tube connector 2 and a head strap 3. In order to facilitate the use of patients carrying nasogastric tubes, a separation groove 11 is provided on the facial mask body 1 in this embodiment, and a separation sheet 12 is embedded in the separation groove 11, and a retention hole 41 is provided on the separation sheet 12 for the nasogastric tube to pass through. A clamping ring 43 for fixing the nasogastric tube is threadedly connected to the retention hole 41. Since the diameter of the retention hole 41 is usually required to be larger than the nasogastric tube, the nasogastric tube can be clamped and fixed by the clamping ring 43 to prevent the nasogastric tube from shaking at will in the retention hole 41, and to prevent the retention hole 41 from being too large, so that the oxygen in the facial mask body 1 leaks too much. In this embodiment, a positioning groove can be provided along the side wall of the separation groove 11, and then the outer edge of the separation sheet 12 is embedded in the positioning groove to achieve the interlocking of the two.

[0025] The purpose of providing the separation groove 11 and the separation sheet 12 in this embodiment is to facilitate the patient to remove the mask while wearing a nasogastric tube. By separating the separation sheet 12 from the facial mask body 1, only the separation sheet 12 is left on the nasogastric tube, which will not interfere with the patient's activities. When putting on the facial mask body 1 again, it is only necessary to reinsert the separation groove 11. If the separation sheet 12 is to be separated from the nasogastric tube, it can be pulled out from the retention hole 41 through the end of the nasogastric tube outside the patient's body; if the separation sheet 12 is to be re-combined with the facial mask body, one end of the nasogastric tube can be inserted into the retention hole 41; if there is no need to wear a nasogastric tube, the separation sheet 12 can also be used normally in combination with the facial mask body 1. Therefore, in this embodiment, the patient can choose to insert a nasogastric tube in advance before wearing the facial mask 1, or can remove the facial mask 1 during the process of wearing the nasogastric tube. Compared with the traditional design of slotting the side of the facial mask 1 to insert the nasogastric tube, this embodiment can reduce oxygen leakage in the facial mask 1 and improve the overall sealing of the facial mask 1, especially in situations where there is no need to wear a nasogastric tube; it can also reduce the discomfort caused by the sharp edges of the slots contacting the patient's face; through one design, it can be suitable for different situations such as wearing a nasogastric tube, not wearing a nasogastric tube, and removing the facial mask 1 during the process of wearing a nasogastric tube.

[0026] In addition, the present embodiment also clamps a sealing sheet 45 for blocking the retention hole 41 between one end of the clamping ring 43 facing the retention hole 41 and the end face of the retention hole 41. This allows the present embodiment to be used for patients who do not need to carry a nasogastric tube, and the retention hole 41 is blocked by the sealing sheet 45, thereby reducing the leakage of oxygen in the facial mask 1. The present embodiment provides a limiting countersunk hole 44 for fixing the sealing sheet 45 at one end of the clamping ring 43 facing the retention hole 41, and then embeds the sealing sheet 45 in the limiting countersunk hole 44, and the sealing sheet 45 is clamped by the bottom of the limiting countersunk hole 44 and the end face of the extension section 42 to achieve sealing and fixing, so that the sealing sheet 45 is blocked on the end face of the retention hole 41. The sealing sheet 45 can be made of rubber or other materials to prevent deformation during the clamping process.

[0027] Specifically, in this embodiment, an extension section 42 (which can be integrally formed with the facial mask body 1) is provided on the side of the retaining hole 41 facing the clamping ring 43, and the end face of the retaining hole 41 is extended. Since the cross-section of the clamping ring 43 is annular in structure, during use, it is easy to thread the inner circumferential surface of the clamping ring 43 and the outer side of the extension section 42 to achieve matching.

[0028] In order to fix the nasogastric tube, in this embodiment, a plurality of clamping claws 46 are arranged on the inner circumferential surface of the clamping ring 43, each of which is in an arc-shaped structure and is arranged circumferentially around the axis of the clamping ring 43. The clamping claws 46 can be preferably designed as a J-shaped structure. The arc-shaped contact surface can reduce damage to the nasogastric tube, facilitate the insertion or removal of the nasogastric tube, and have elastic deformation ability to clamp the nasogastric tube. The clamping claws 46 should be arranged on the side of the limiting counterbore 44 away from the retention hole 41 to avoid contact with the sealing sheet 45.

[0029] In addition, in order to further improve the comfort of this embodiment, this embodiment is provided with a sealing edge 47 at the edge of the facial mask body 1, and the sealing edge 47 is made of a hydrocolloid dressing. It can better protect the patient's facial skin and increase the patient's comfort during long-term wearing.

[0030] During use of this embodiment, if the patient does not need to carry a nasogastric tube, the mask can be used normally. If a nasogastric tube is needed, in addition to the conventional oxygen tube connection, the mask can be used normally by unscrewing the clamping ring 43, removing the sealing sheet 45, and then screwing the clamping ring 43 onto the extension section 42 of the retention hole 41, and then passing the nasogastric tube through the clamping ring 43 and the retention hole 41, and fixing it with the clamping claws 46 in the clamping ring 43, and finally wearing the facial mask 1 normally.

[0031] In order to further reduce oxygen leakage, another implementation method can be provided, in which a sealing strip made of a flexible sealing material is provided on the side of each clamping claw 46, so that the sealing strips on two adjacent clamping claws 46 can fit and seal according to the distance after clamping the nasogastric tube, thereby closing the gap between adjacent clamping claws 46.

[0032] To facilitate the placement of the nasogastric tube, the present embodiment may also provide a group of retention holes 41 on both sides of the facial mask body 1 to reduce the bending of the nasogastric tube.

[0033] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
