DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1-7 The present invention provides a technical solution: a breathing mask for critically ill patients, comprising a mask body and a mask mounting seat, wherein the mask body is used for protective treatment and oxygen supply of the patient, and the mask mounting seat is convenient for wearing the mask body on the patient's face, and the mask mounting seat can be used to adjust the angle and posture of the patient's head, and the specific structures of the two are as follows: The mask body comprises a mask 1, and a plurality of fixing straps 2 are fixed to the side of the mask 1; The mask mounting seat includes a bottom plate 11, a rotating plate 12 with an adjustable angle is rotatably provided on one side of the bottom plate 11, a curved headrest 15 with an adjustable angle is rotatably provided on the side of the rotating plate 12, and a plurality of ear plates 16 for positioning the fixing belt 2 are provided on the side of the curved headrest 15; Preferably, three fixing straps 2 are provided, one on each side and another on the middle of the side. Figure 1 or Figure 6 As shown, the number and position of the ear plates 16 correspond to the number and position of the fixing belts 2. The wearing strength of the mask 1 can be ensured by multi-angle positioning. When the mask 1 is worn, the medical staff passes the multiple fixing belts 2 through the ear plates 16 for fixing, so that the mask 1 can be effectively worn on the patient's face. Compared with the traditional mask wearing method, the wearing method in this solution can reduce the lifting of the patient's head, which is convenient for monitoring or treatment of the patient, and avoids the inconvenience of wearing caused by the patient's head trauma. Moreover, it can be operated by one person, and it is easy to wear, replace or remove the mask 1; In addition, in the above scheme, the angle of the patient's head support can be adjusted by adjusting the angle of the rotating plate 12, so as to prevent the patient from being in a supine position for a long time when in a coma, causing the tongue to fall and block breathing, or the fluid accumulated in the mouth to flow back into the respiratory tract and cause the patient to have difficulty breathing. At the same time, the tilt angle of the patient's head can be adjusted by rotating the arc-shaped headrest 15, so as to facilitate treatment with the patient's head in different postures.

[0019] A mounting opening is provided on the side of the mask 1, and an oxygen supply tube 6 with an adjustable position is provided in the mounting opening. The oxygen supply tube 6 is used to supply oxygen for the patient to breathe.

The oxygen supply tube 6 is set according to the patient's condition, and oxygen is inhaled through the nose or mouth. The position of the oxygen supply tube 6 is adjustable, so that an appropriate length of the oxygen supply tube 6 can be reserved in the mask 1 according to usage requirements.

[0020] A plurality of arc-shaped splints 3 are fixed to the side of the mask 1 near the mounting opening, and a gap is provided between two adjacent arc-shaped splints 3. The plurality of arc-shaped splints 3 form a cylinder, and the oxygen supply tube 6 is slidably arranged in the cylinder.
