[0033] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0034] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0035] In related technologies, oxygen masks are generally fixed to the patient's mouth and nose by straps along the patient's left and right cheeks. When the patient moves, the oxygen mask will move relative to the patient along the symmetry axis of the face, resulting in poor fit between the oxygen mask and the patient and oxygen leakage, affecting the oxygen supply effect, and the mask or other parts press on the patient's eye sockets, causing discomfort to the patient.

[0036] In view of this, if Figures 1 to 4 As shown, some embodiments of the present invention provide an oxygen mask, comprising: a mask 1 and a fixing assembly; the fixing assembly comprises an extension portion 2 and a connecting strap, the length direction of the extension portion 2 is consistent with the length direction of the mask 1, one side of the mask 1 is connected to the extension portion 2, and the connecting strap surrounds the patient along the top of the patient's head and is connected to the extension portion 2.

[0037] In the above embodiment, the mask 1 can be made of transparent material, including transparent polycarbonate and polyethylene. The mask 1 covers the patient's mouth and nose and leaves a cavity between the patient's mouth and nose. The side of the mask 1 away from the patient is provided with an oxygen supply tube for supplying oxygen to the cavity, so that the patient can inhale the oxygen in the cavity through the mouth and nose. Figure 2 In the direction shown, an extension portion 2 is provided above the mask 1, and the extension direction of the extension portion 2 is Figure 2 The connecting belt is then fixed to the patient's head through the connecting belt and connected to the patient's mask 1 and the extension part 2. The connecting belt can be passed through the patient's back of the head and around the left and right sides to the patient's cheek position to connect to the mask 1 to fix the mask 1. Then, it can also be passed through the patient's head position to the extension part 2 for fixing, so that the mask 1 and the extension part 2 can be connected. Figure 2 The mask 1 is fixed on the left and right sides in the direction, and the extension part 2 is also fixed to prevent the extension part 2 and the mask 1 from moving downward. The connecting belts that pass through the left and right sides of the patient and go around the patient's cheeks can be set on the side of the patient's ear away from the cheek. When the mask 1 moves upward, it can be fixed by the ears and the connecting belts on the left and right sides to prevent the mask 1 from moving upward, so that the mask 1 and the extension part 2 are fixed, the mask 1 fits the patient more firmly, is not easy to leak, and the patient is more comfortable when using it.

[0038] The connecting strap may be made of an elastic material, such as rubber, and the connecting strap may fix the extension portion 2 and the mask 1 on the patient's face through elastic force, making the connection more secure.

[0039] Some embodiments of the present invention provide an oxygen mask, comprising: a mask 1 and a fixing assembly; the fixing assembly comprises an extension portion 2 and a connecting strap, the connecting strap surrounding the patient along the top of the patient's head and connected to the extension portion 2, thereby preventing the mask 1 and the extension portion 2 from moving in the length direction of the mask 1 when the patient moves, causing oxygen leakage and the mask 1 or other parts pressing on the patient's eye sockets, causing patient discomfort. This solves the technical problem in the prior art that the mask 1 moves relative to the patient, causing oxygen leakage and patient discomfort, and achieves the technical effect that the mask 1 fits the patient more firmly, is not prone to leakage, and is more comfortable for the patient when used.
