Abstract: The present invention discloses a radiotherapy patient-positioning shell, which comprises a low-temperature thermoplastic board fabricated to have different positioning zones for different regions of the human body. Each positioning zone has holes. Different positioning zones respectively have different layout densities of the holes. The radiotherapy patient-positioning shell of the present invention has optimized structure and superior usability. The layout densities of different positioning zones of the radiotherapy patient-positioning shell are varied according to requirements of different regions of the human body. Thereby, different positioning zones will have different degrees of contraction and apply different intensities of fixing force to the related body regions. Thus is promoted the comfort of the user and prolonged the service life of the radiotherapy patient-positioning shell without affecting the fixing force thereof.

Abstract: A low-temperature thermoplastic plate with velvet layer comprises a low-temperature thermoplastic plate and a velvet layer, wherein the low-temperature thermoplastic plate has meshes, and wherein the velvet layer is fixed to the regions which are on the top of the low-temperature thermoplastic plate and outside the meshes. The low-temperature thermoplastic plate with velvet layer of the present invention with velvet layers attached to the top and bottom thereof has rational and compact structure. Thereby, the low-temperature thermoplastic plate with velvet layer of the present invention has high gas permeability, high sweat absorbance and high extensibility and is comfortable for users and easy to work. Besides, the low-temperature thermoplastic plate with velvet layer of the present invention can be mass-produced in high efficiency.
