For example, magnets are arranged in the plurality of positioning grooves, and a steel positioning block of the elastic pulling rope is detachably clamped and adsorbed in one of the positioning grooves, so that the distance between the nose part of the laminated cover body and the nose part of the laminated cover body is changed by the elastic pulling rope.

Referring to fig. 1 and 2, a positive pressure ventilation mask 100 for department of respiration includes a connection elbow 10, a shell 20, a strap (not shown) and a flexible cover 40, the connection elbow is connected to the flexible cover, the shell is sleeved on the connection elbow and fixed on the flexible cover, two opposite ends of the strap are respectively connected to two opposite sides of the shell, the flexible cover includes a main body cover 41 and a laminated cover 43, the laminated cover is disposed on the main body cover, the shell is fixed on the laminated cover, a flexible recess 45 is disposed between the laminated cover and the main body cover,

noses

411 and 431 are formed on the laminated cover and the main body cover, an elastic pull rope 46 is disposed on the bottom of the main body cover, a steel positioning block is disposed on the end of the elastic pull rope, and a plurality of positioning grooves 435 are disposed on the nose of the laminated cover, the distance between the plurality of positioning grooves and the body of the main body cover is different, magnets are arranged in the plurality of positioning grooves, and steel positioning blocks of the elastic pull rope are detachably clamped and adsorbed in one of the positioning grooves, so that the distance between the nose part of the stacked cover body and the nose part of the stacked cover body is changed by the elastic pull rope.

For example, the usage process of the positive airway pressure mask in the department of respiration specifically includes the following steps: the flexible mask is covered on the nose and mouth of a patient, the bandage is sleeved on the hindbrain of the patient, the positive pressure ventilation mask for the department of respiration is worn on the face of the patient, and the connecting elbow is communicated with the treatment mist. When the nose of the patient is short, the nose of the laminated cover body is pressed to enable the flexible concave part to contract, and the steel positioning block is clamped in a proper positioning groove, so that the flexible concave part is fixed. Because the positive pressure ventilation mask for the department of respiration is provided with the elastic pull rope and the positioning groove, the nose part of the main body mask body and the nose part of the laminated mask body can be pulled by the elastic pull rope, so that the width of the flexible concave part is changed, and the height of the nose part of the laminated mask body is adjusted to adapt to the heights of the noses of different patients.

For example, in order to more stably pull the nose portion of the laminated cover, the nose portion of the main body cover is a first nose portion 411, the nose portion of the laminated cover is a second nose portion 431, the number of the elastic pulling ropes is two, and the two elastic pulling ropes are respectively connected with two opposite sides of the first nose portion.

The two elastic pull ropes are respectively a first elastic pull rope and a second elastic pull rope, and the lengths of the first elastic pull rope and the second elastic pull rope are different. The steel positioning block on the first elastic pull rope is clamped in one of the first group of positioning grooves, and the steel positioning block on the second elastic pull rope is clamped in one of the second group of positioning grooves. The elasticity of the first elastic pulling rope and the elasticity of the second elastic pulling rope are both smaller than the elasticity of the flexible concave part. Through setting up two elasticity stay cords, draw respectively from both sides and hold the nasal part of range upon range of cover body to make the deformation of flexible depressed part is more even, wears the effect better. And the first elastic pull rope and the second elastic pull rope are arranged in different lengths, so that one side of the second nose part, which is far away from the first nose part, can be pulled and held, and the contraction and movement of the second nose part are ensured.

For example, to facilitate the fit with the mouth of the patient, the main body mask further includes a first main body 413 on which the first nose portion protrudes, and the laminated mask includes a second main body 433 on which the second nose portion protrudes. The first body portion has a width greater than a width of the first portion, and the second body portion has a width greater than a width of the second nose portion. The first main body part is directly connected with the second main body part, and the first nose part is connected with the second nose part through the flexible concave part.
