Description

Portable elderly patient walking assistance nursing device Technical Field The invention relates to the technical field of rehabilitation auxiliary instruments, in particular to a portable walking assisting nursing device for old patients. Background The prior art is mainly divided into two types, namely a passive supporting type which provides stable support for a user through a rigid or lockable joint structure, but is generally large in weight and insufficient in flexibility, and is difficult to adapt to natural gait, and an active driving type which directly drives the joint to move through a power source such as a motor, and the like, wherein the auxiliary effect is good, but the structure is complex, the cost is high, the energy consumption is high, and potential safety hazards exist once the power fails. Regardless of the type of device described above, the weight and center of gravity distribution of the device are critical factors affecting wear comfort and safety in use. Existing devices typically distribute weight statically to the user's limb, adding additional load to the user. Particularly, at the moment when the body of a user is unbalanced and falls about to fall, the existing device cannot always provide effective reverse balance moment due to the fact that the mass of the existing device is fixedly connected with a human body, and even the falling trend is aggravated, so that higher safety risks exist. Therefore, there is an urgent need for a walking aid device that can actively cope with an unbalanced state while reducing the load on the user and improve the safety of walking. Disclosure of Invention Aiming at the defects in the prior art, the invention provides a portable walking assisting nursing device for elderly patients, which is used for actively coping with an unbalanced state and avoiding the elderly patients from toppling over. The portable walking assisting nursing device for the elderly patients comprises a main body supporting structure, a counterweight part and a driving part, wherein the main body supporting structure sequentially comprises a waist fixing component, a thigh supporting component, a knee joint component, a shank supporting component and a foot component from top to bottom along lower limbs of a human body, the thigh supporting component and the shank supporting component are of cavity structure design, the sensing part is arranged on the main body supporting structure and comprises at least one gesture sensor group and a controller, the gesture sensor group is used for sensing body gesture change of a user, one end of the controller is electrically connected with the gesture sensor group, the counterweight part is arranged on the main body supporting structure and is respectively positioned in the thigh supporting component and the shank supporting component, the counterweight part is electrically connected with the other end of the controller of the sensing part, and when the gesture sensor group detects a counterweight indicating that a human body is about to incline abnormally, the controller immediately sends a command to the counterweight part, and the driving part is rapidly moved along the opposite direction of the human body.
