By adjusting the distance between the first Velcro 9 and the second Velcro 10, the length of the chest fixing belt 6, the abdomen fixing belt 7, and the hip fixing belt 8 can be adjusted to fit the patient's body closely to prevent the body from shaking during the puncture process. Since the patient is firmly and comfortably fixed in a suitable position, the puncture deviation caused by the movement of the patient is reduced. Therefore, the patient's comfort is fully considered, and skin damage and poor blood circulation in the limbs caused by excessive restraint are avoided;

[0047] In actual use, the staff can start the electric slider 14 and the electric guide block 16 according to the required puncture position, and can adjust the position of the puncture plate 12, which can be adjusted according to different puncture sites, so as to improve the accuracy and convenience of puncture.

[0048] In addition, the drainage tube can be placed in the placement port 19. At this time, the limit block 22 can squeeze the drainage tube under the pressure of the limit spring 21, so that the drainage tube can be easily fixed to prevent the drainage tube from twisting or shifting. Therefore, the multifunctional effect of the fixed bed can be achieved.
