Linkage device for promoting limb rehabilitation

Abstract

The invention discloses a linkage device for promoting limb rehabilitation. The linkage device comprises a shell, a control piece, a water tank and a pump body are arranged in the shell, the water outlet pipe of the pump body communicates with a three-way piece, the outlet of the three-way piece is provided with a first communicating pipe and a second communicating pipe, valve bodies are arrangedon the first communicating pipe and the second communicating pipe, one end of the first communicating pipe is communicated with the three-way piece, a first liquid bag is arranged at the other end ofthe first communicating pipe, one end of the second communicating pipe is communicated with the three-way piece, a second liquid bag is arranged at the other end of the second communicating pipe, thelinkage device comprises an oversleeve, and pressure sensors are arranged on the first liquid bag and the second liquid bag. According to the linkage device, the arm / leg is sleeved with the oversleeve, pulling pieces on the first liquid bag and the second liquid bag are pulled to make the first liquid bag located at the elbow joint / knee joint, so stretching of the arm / leg and intermittent rotationof the pump body are achieved, reciprocating motion of the arm / leg is achieved, and the purpose of exercising is achieved.

Description

technical field [0001] The invention relates to a linkage device, in particular to a linkage device for promoting rehabilitation of limbs. Background technique [0002] Patients after stroke mainly rely on passive muscle training. The linkage system in the prior art has the following disadvantages: 1. It is not safe and comfortable, and it is easy to hurt the user; 2. It does not have a temperature adjustment function and is uncomfortable to use in winter. ; 3. Traditional exoskeleton robots are driven by motors. Long-term training may easily cause the motors to overheat or the torque of some motors may be insufficient due to individual differences in patients. Contents of the invention [0003] The purpose of the present invention is to provide a linkage device for promoting limb rehabilitation. Put the sleeve on the arm / leg, and pull the pulling parts on the first liquid bag and the second liquid bag, so that the first liquid bag is located at the elbow joint / At the kn...
