The invention relates to a multifunctional electric cart with an enclosing barrier for facilitating excretion of high-level quadriplegia patients, belonging to the technical field of medical equipment. As a high-level quadriplegia patient sits on a wheel chair for a long term, the lower part of the body is amyotrophic and the upper limbs become very weak; and a conveying tool taken by the high-level quadriplegia patient has huge defects and cannot meet requirements on various aspects of the high-level quadriplegia patient. In the technical scheme provided by the invention, the bottom surface of an inflating supporting stand column (23) is fixed on a foot pedal (22), the foot pedal (22) is fixedly arranged on a base fixing plate (6) provided with two electric cart wheels (24) and a universal wheel (7), a storage battery (25) is arranged on the base fixing plate (6), and the upper surface of the inflating supporting stand column (23) is provided with two grooves (17) for placement of legs. The multifunctional electric cart has the advantages of multiple functions and wide application range, can meet overall needs of high-level quadriplegia patients, brings great convenience to the living and the medical treatment for the high-level quadriplegia patients, and fills a gap on equipment for serving the high-level quadriplegia patients.
