Description

Technical Field

[0001] The utility model relates to the technical field of respiratory assist devices, in particular to an adjustable breathing mask. Background Art

[0002] Respiratory masks are usually used to assist breathing, such as providing oxygen support to patients with breathing difficulties, or providing anesthetic gases to patients during surgery. When the patient requires external support and uses a ventilator, a respiratory mask is needed as a connector between the air supply tube on the ventilator and the patient's face to provide breathing support to the patient.

[0003] Chinese patent announcement number CN215135380U discloses an adjustable breathing mask, including a mask body, and also including a plurality of sealing rings for fitting the face, the plurality of sealing rings are arranged in sequence from the inside to the outside, the area enclosed by the plurality of sealing rings arranged from the inside to the outside increases in sequence, two adjacent sealing rings are connected by a flexible folding portion, and the sealing ring with the smallest enclosed area among the plurality of sealing rings is fixedly connected to the mask body. Although the patent can select different sealing rings according to the size of different people's faces, the fixing belt of the patent adopts a fixed length elastic design. If the fixing belt is too tight, it may cause the wearer to feel uncomfortable or even cause a sense of pressure on the head; if the fixing belt is too loose, it may cause the breathing mask to not fit the face tightly, affecting the breathing effect. In the actual production process, in order to prevent the respiratory mask from becoming too loose or sliding during wearing, the manufacturer generally adjusts the fixing strap of the respiratory mask to be tighter; due to the differences in facial bone shapes of different patients, some patients have higher cheekbones. At this time, when wearing a respiratory mask, the bottom edge of the respiratory mask will exert greater pressure on the cheekbones of the patient with higher cheekbones. If worn for a long time, it will not only cause more obvious pressure on the higher areas of the patient's face, but also cause damage to the facial muscles, and may even cause facial pressure sores in the patient.
