[0022] By adopting a rounded design on the front of the pillow base 1, it can provide a more fitting and comfortable support for the user's neck and head. Especially for patients with CVC catheters on the right side of their neck, the rounded design can leave space to avoid compression of the catheter, thereby ensuring its stability and safety. Furthermore, the inclined grooves 103 on both sides of the top of the pillow base 1 increase the pillow's adjustability and facilitate the installation of the cloth strap 201 and the adjustable pillow 2. By adjusting the position of the cloth strap 201 in the inclined groove 103, the height and angle of the adjustable pillow 2 can be easily adjusted to meet the personalized needs of different users.

[0023] like Figures 4 to 5 As shown, the pillow base 1 is U-shaped, and the two adjustable pillows 2 are triangular. Several ventilation holes 101 are provided on the outer wall of the lowest point of the U-shape of the pillow base 1. The ventilation holes 101 all penetrate the pillow base 1 and are distributed in an equidistant array.

Insert the fabric straps 201 at the top of the two adjustable pillows 2 into the corresponding oblique grooves 103. Carefully adjust the height of the two adjustable pillows 2 according to the patient's head circumference. After determining the height, first, use the Velcro loop side 202 and the Velcro hook side 102 for initial fixation, ensuring the adjustable pillows 2 will not move arbitrarily. Then, use the Velcro loop side 2011 and the Velcro hook side 2011 for further fixation. The 104-fold fit provides secondary fixation. The ventilation holes 101 on the pillow base 1 significantly improve air circulation, effectively reducing stuffiness and enhancing the user's overall comfort. Especially during prolonged bed rest, the ventilation holes 101 prevent skin dampness and discomfort. The adjustable protrusions 203 on the pillow 2 provide additional support and a massage effect, helping to relieve pressure on the neck and head. The rounded design on the front of the pillow base 1 is particularly suitable for patients with CVC catheters on the right side of the neck. The rounded design provides space to ensure that the catheter will not bend or shift due to pressure, thus maintaining its original fixed position.
