Bed device
A bed device includes: an operation section that receives an operation input; a controller that controls a movement of the bed in accordance with the operation input; a detector that detects a position of a patient on the bed; and, a limitation table that stores a limitation area set on the bed in association with a limitation content, wherein when the position of the patient detected by the detector is included in the limitation area, the limitation content is read out from the limitation table so as to control the controller in accordance with the limitation content. With this configuration, it is possible to provide a higher safety bed device which can not only notify the danger based on the bed movement but also limit the movement of the bed in accordance with the status of the patient or the bed device.
1. A mattress system comprising:
an air mattress including first air cells extending in a first direction, a second air cell extending in a second direction crossing the first direction, the second air cell being provided under the first air cells;
an input unit configured to input an instruction of the user;
a detector configured to detect a condition of the air mattress;
a memory configured to store a table, the table including limited movements of the air mattress associated with conditions of the air mattress; and
a controller configured to control an operation of the air mattress based on the instruction, the controller being configured to limit the associated movement of the air mattress if the condition of the air mattress satisfies a condition stored in the table,
wherein the limited movements of the air mattress stored in the table are further associated with a type of the instructions.
2. The mattress system according to claim 1 , wherein the controller is configured to continue to limit the movement of the air mattress even if the input unit receives the instruction.
3. The mattress system according to claim 2 , wherein the controller is configured to temporarily suspend the movement of the air mattress if the condition of the air mattress is satisfied with a first condition.
4. The mattress system according to claim 2 , wherein the controller is configured not to limit the movement of the air mattress if the condition of the air mattress is satisfied with a first condition and the input unit receives a second instruction, and the second instruction is different from the first instruction.
5. The mattress system according to claim 4 , further comprising:
a memory configured to store a table, the table including limited movements of the air mattress, the limited movements being associated with type of the instructions and conditions of the air mattress.
6. The mattress system according to claim 1 , further comprising:
an output unit configured to notify an alarm if the controller is configured to suspend the movement of the air mattress.
7. The mattress system according to claim 5 , further comprising:
an output unit configured to notify an alarm if the controller is configured to suspend the movement of the air mattress.
8. The mattress system according to claim 7 , wherein the controller is configured to decide whether the controller resumes the movement of the air mattress after suspending the movement of the air mattress.
9. The mattress system according to claim 8 , wherein the limited movement of the air mattress is a rolling function of the air mattress.
10. The mattress system according to claim 9 , wherein a first condition is a condition an angle between a back portion of the air mattress and a floor exceeds to a first angle, or a condition a part of body of the user is in a first area on the air mattress.
11. A method of a mattress system including an air mattress, a detector, and a controller, the air mattress including first air cells extending in a first direction and a second air cell extending in a second direction crossing the first direction, the second air cell being provided under the first air cells, the detector being configured to detect a condition of the air mattress, the method comprising:
receiving an instruction of a user to execute a movement of the air mattress;
detecting the condition of the air mattress by the detector;
limiting the movement of the air mattress if the condition of the air mattress is satisfied with a first condition, and
not limiting the movement of the air mattress if the condition of the air mattress is satisfied with a first condition and the input unit receives a second instruction, and the second instruction is different from the first instruction.
12. The method according to claim 11 , wherein a step of the limiting the movement of the air mattress continues even if the input unit receives the instruction.
13. The method according to claim 12 , wherein a step of the limiting the movement of the air mattress is a step of suspending the movement of the air mattress if the condition of the air mattress is satisfied with a first condition.
