The medical effects of Ouvert (which means "open" in French) are as follows: "It restores finger function in patients with hemiplegia due to stroke, etc. This product moves the joints by constantly flexing and extending the fingers, thereby preventing adhesion and contracture of the joints and improving the range of motion of the joints." The patient places their paralyzed and healthy hands on the robotic hands of this product. The robotic hands are electrically connected to each other, driven by individual motors, and their positions are detected by encoder sensors. When the patient moves the robotic hand on which the healthy hand is placed, the robotic hand on which the paralyzed hand is placed moves in perfect synchronization in the opposite direction. This movement flexes and extends the joints of the paralyzed hand. It is remarkable that patients can independently carry out rehabilitation by moving their own healthy hand. This product implements a mirror therapy function that displays on the display an image of the normal hand taken by a camera and a mirror image that is reversed left and right by image processing. In addition, during training, the product has a game function that projects a character (beans, etc.) onto the image of the training hand on the display and has the patient catch the character with the paralyzed hand. The product consists of the main unit, AC adapter and display set. The product has built-in software that controls the motors, camera, LEDs, image processing and display of the mechanisms within the main unit, as well as setting the range of motion, etc.
