[0006] The protective mechanism includes a fixed arc plate, a first rotating shaft, an upper arc plate, a Velcro female patch, a Velcro male patch, an observation port, a second rotating shaft, an observation window, a semi-convex ball, a groove, a pull block, a ventilation window and a filter screen. The fixed arc plate is fixed to the back plate, the upper arc plate is installed on the top of the fixed arc plate through the first rotating shaft, the Velcro female patch is arranged on the outside of one side of the fixed arc plate, the Velcro male patch is arranged on the inside of one side of the upper arc plate, an observation port is opened in the middle of the upper arc plate, an observation window is installed in the observation port through the second rotating shaft, a semi-convex ball is arranged in the middle of one end of the observation window, and a pull block is arranged on the outside of one end of the observation window.
[0007] Preferably, a rubber pad is provided on the inner surface of the fixed arc plate.
[0008] Preferably, the female Velcro patch and the male Velcro patch have the same shape.
[0009] Preferably, a groove is provided on the upper arc plate at a position corresponding to the semi-convex sphere.
[0010] Preferably, the observation window is a component made of a transparent material.
[0011] Preferably, a plurality of ventilation windows are provided on both sides of the upper arc-shaped plate, and filters are installed inside the ventilation windows.
[0012] Beneficial effects: When the utility model is used, the back plate is placed on the patient's back and the arm fixing belt is passed through the armpit and fixed on the corresponding fixing ring, and then the chest fixing belt is tied to the chest. The patient's neck is located in the fixed arc plate, and the upper arc plate is clamped on the fixed arc plate and fixed by the Velcro mother patch and Velcro male patch.
