  However, in the above-described conventional wheelchair, when a physically handicapped person adds work, the work cannot be added unless the wheelchair 10 is pushed to the toilet. Furthermore, when the patient's legs are inconvenient, nurses and family members have to lift and sit on the toilet, which is very difficult for the family and patients.

The foldable folding wheelchair 10A described in Patent Document 1 (see FIGS. 2A and 2B) is different from the conventional wheelchair 10 in that the frame 120 of the wheelchair is mounted on the two movable poles 121. A seat 130 is installed above the wheelchair frame 120, and a receiving toilet 140 is installed below the wheelchair frame 120, so that the user can use the wheelchair 10A.
However, in such a structural design, the user can directly use the wheelchair 10A. However, since the seat 130 is formed of plastic and has the excretion hole 131, the wheelchair 10A is folded. In some cases, the sheet 130 and the receiving toilet 140 must be removed, which is inconvenient in use. Further, since the excretion hole 131 of the seat 130 is a fixed opening, it is inconvenient when the user uses the wheelchair 10 as shown in FIG. It was not practical.
Such a patent refers to a previous plan such as “a structure of a combination wheelchair having a toilet seat function” described in Patent Document 2, for example. Any wheelchair with a conventional receiving toilet or toilet function has a problem that it is inconvenient to remove and install, so there is room for improvement.

  The present invention has been created in view of the above points, and an object of the present invention is to provide a foldable wheelchair that can be excreted. That is, an object of the present invention is to provide an excretable folding wheelchair that can be used directly by a handicapped person on a wheelchair, can be used as a general wheelchair during normal times, and is easy to carry. .

  In order to solve the above-described problems and achieve the object, an excretory foldable wheelchair according to the present invention includes a foldable wheelchair frame and a foldable seat coupled between the wheelchair frames. In the middle of the sheet, an excretion device installed at the discharge port and the bottom surface of the sheet is installed. In the excretion device, when the cushions are respectively installed on the upper surface and are closed, the two cushions correspond to each other so as to face each other and the two shielding plates protruding into the discharge port. Are installed on the bottom and two sides of the two shielding plates, and the two shielding plates are closed by the operation of being pulled or pushed, and the discharge port is closed or opened to open the discharge port. When the two brake members used for the purpose and the bottom end of the inner side of the two shielding plates are hung and deployed toward the bottom of the two shielding plates, the opening portion is synchronized. A receiving bag that is opened and used to receive the waste.

  By the above technical means, the present invention becomes the same as a general wheelchair at the normal time, and can be folded and transported by a car. When the user adds work, the user can operate directly on the wheelchair and open the excretory device. Furthermore, since the user's buttocks are cleaned by the cleaning device, the patient does not have to descend or sit down from the wheelchair, and can be excreted and cleaned by himself. It is a wheelchair designed to be friendly to people, while protecting the dignity of patients, improving convenience, and reducing the burden on nurses and families.
