Improved deep venous thrombosis prevention device

The invention provides an improved deep venous thrombosis prevention device. The improved deep venous thrombosis prevention device mainly comprises a massaging device (1) and a folding portion (2). The two portions of the folding portion (2) are located on the inner and outer sides of the two ends of a cylindrical shell respectively. The folding portion (2) is at least provided with a fixing device (21). The inside dimension of the massaging device (1) is adjusted by adjusting a male buckle (2111) and a female buckle (2112) of the fixing device (21), a sticky tearing belt (2121), lint (2122) and a bundling belt (213). The massaging device (1) is internally provided with an inflatable device (12). The inflatable device (12) is connected with an electric inflation device (122) to be controlled by a timer (33). The function of a muscle pump is achieved, and it is ensured that a massaging paster (13) is tightly attached to the human limbs through a stretchable belt with an electric motor (12). The improved deep venous thrombosis prevention device can partially or completely cover the massaging device of the human limbs stably when in use.
