Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 6, a memory foam shaping device for radiotherapy human body shape comprises a radiotherapy bottom plate 1 and a memory foam pad 2 disposed on the radiotherapy bottom plate 1;

the radiotherapy bottom plate 1 is flat, two sides of the surface of the radiotherapy bottom plate 1 are spliced with guard plates 3, and the guard plates 3 are perpendicular to the radiotherapy bottom plate 1; radiotherapy bottom plate 1 is carbon fiber integration board, and this radiotherapy bottom plate 1 can cover the great half of the body of human body, the material of backplate 3 with the material of radiotherapy bottom plate 1 is the same.

The memory foam pad 2 is composed of memory foam and a skin layer 21 wrapping around the memory foam 22, before use, the memory foam 2 is in a pre-compression state, the compression rate is 1/2-1/3, the compressed foam is more beneficial to rapid heat conduction when being heated, the softening time is shortened, the size is small, and the transportation cost can be greatly reduced; the foam pad can be shaped according to the requirement, for example, as shown in fig. 3, in order to adapt to the shape of the head, neck and shoulder of the memory foam pad 2, when a human body lies on the foam pad, the shape can be shown in fig. 5; if the waist needs to be shaped, it can be referred to fig. 6.
