This invention discloses a low-temperature thermoplastic composition and the low-temperature thermoplastic material made therefrom, as well as its applications, relating to the field of medical materials technology. The low-temperature thermoplastic composition mainly comprises the following components: thermoplastic resin, reinforcing filler, and radiation crosslinking agent; the thermoplastic resin includes polyurethane, and each 100 parts of the low-temperature thermoplastic composition contains at least 27 parts of a first polyurethane with a flow start temperature of 50-95°C and an open time of at least 6 minutes. Through the selection of polyurethane and the combination of reinforcing filler, the low-temperature thermoplastic composition enables the low-temperature thermoplastic material to have lower shrinkage and a longer operating time, allowing the low-temperature thermoplastic material prepared from the composition to be used for fixation of parts with higher operating time requirements.

The application discloses a kind of pelvic floor muscle training devices, including at least two air bags, air pipe and charge and discharge component, wherein, air bag includes probe part and bending part, probe part and bending part are communicated, probe part and bending part inside are hollow structure, air pipe is connected with the end of probe part away from bending part, charge and discharge component is connected with the end of air pipe away from probe part, charge and discharge component is configured to charge and discharge air bag by air pipe, to make probe part and bending part swell and shrink.The above scheme provided by the application, charge and discharge air bag by charge and discharge component, at this time, probe part and bending part can swell and shrink, so in the process of swelling and shrinking, pelvic floor muscle can be pressed and relaxed uninterruptedly, so as to improve the contraction force and coordination of muscle group at pelvic floor muscle, to enhance the massage effect of pelvic floor muscle.

The application discloses an asymmetric bag type pneumatic artificial muscle and a manufacturing method thereof. The asymmetric bag type pneumatic artificial muscle comprises an upper film cloth, a lower film cloth, a plurality of air bags, a winding belt and a gas source system. The upper film cloth is overlapped with the lower film cloth. The air bags are sequentially arranged on the upper film cloth and located between the upper film cloth and the lower film cloth. The distance between the two side edges of the air bag and the lower film cloth is less than the length of the air bag along the outer surface. The winding belt sequentially passes through the upper film cloth and the lower film cloth and passes through each air bag. The two ends of the winding belt are fixed on the lower film cloth. The gas source system is communicated with the air bag. The air bag is formed by folding and heat sealing the upper film cloth and the additional film cloth on the upper film cloth. The expansion of the air bag only drives the expansion of the upper film cloth to form one-side expansion. The human body is directly contacted with the lower film cloth, so that the human body is avoided from being squeezed.
