Disclosed is a multifunctional care bed for patient self-defecation, comprising: a bed body (10), a bed plate member (20), a top support mechanism (30A, 30B), a defecation device (4), a washing mechanism (50), a urine blocking device (60), a covering device (70), and a control device (90) which is electrically connected to the above-mentioned devices and is used for controlling the devices being on or off. When a patient wants to defecate, the control device (90) commands the top support mechanism (30A, 30B) to start up to move the bed plate member (20) upwards while the covering device (70) rises and opens and the bed plate member (20) descends back to its original position, and at the same time the covering device (70) is pressed and sinks, a urine mask of the urine blocking device (60) rises, showing a state of use for the patient. Whereby, the multifunctional care bed can be used for the patient to perform defecation actions directly on the bed, and can reduce the burden on patients, improve the convenience for patients defecation, and achieve the effect that patients can take care of themselves without the help of others.La présente invention concerne un lit de soins multifonctionnel permettant au patient de déféquer seul, comprenant : un corps (10) de lit, un élément plaque (20) de lit, un mécanisme de support supérieur (30A, 30B), un dispositif de défécation (4), un mécanisme de lavage (50), un dispositif (60) de blocage durine, un dispositif de recouvrement (70), et un dispositif de commande (90) qui est connecté électriquement aux dispositifs précités et est utilisé pour commander la mise en marche ou larrêt des dispositifs. Lorsquun patient souhaite déféquer, le dispositif de commande (90) permet de commander au mécanisme de support supérieur (30A, 30B) de démarrer le déplacement de lélément plaque (20) de lit vers le haut pendant que le dispositif de recouvrement (70) monte et souvre et que lélément plaque (20) de lit redescend vers sa position initiale,
