To provide a multifunctional nursing care medical instrument wherein the burden in terms of time, mind, physical strength and costs is reduced for a care giver.

In the nursing care medical instrument, for changing into a wheelchair from the bed where a patient lies, when a backrest is lifted with the aid of a rising spring 16, an arm rest 6 and a footrest are simultaneously set to fixed positions while keeping horizontal states. An armchair is used when taking a rest and set by a base point pin 11 when used as a wheelchair or the like. Filth in an excreta tank 22 is processed by a toilet at home and put in a storage place 27 again. When moving, a getting-on/off safety metal fixture 14 of the footrest is lifted up and a brake is released. When eating or reading, a table plate stored in the backrest at the back is engaged with the armrest 6 for use. When excreting, the body is raised by a pull-up rod 20, it is easy to take off/put on the clothes or put things right later. The pull-up rod 20 is also very helpful to prevent bedsores, for turning over while asleep, and for arm exercises. A sunshade is provided as well so as to prevent the sun when going out, so that it works as a rain cover. A pushing handle 18 of the wheelchair serves as a leg when it is used as a bed.
