The internal pressure setting is a set value of the internal pressure of the air cell 120. In the example of FIG. 3, a value of 14 to 22 mmHg is registered as the internal pressure setting. A plurality of internal pressure setting values may be provided so that the internal pressure can be set for each air supply system. The expansion / contraction cycle setting indicates a temporal period in which the air cell 120 connected to each air supply system is periodically expanded and contracted. In the example of FIG. 3, a value of 5 minutes is registered as the expansion / contraction cycle setting. As the setting information of the air mattress 100, the degree of fluctuation of the internal pressure of the air cell 120 according to the back-raising state of the user may be stored. Further, as the setting information of the air mattress, information for managing the internal pressure in each mode set according to the user's condition such as the back-raising mode corresponding to the back-raising state and the contracture mode corresponding to the contracture state. May be registered. Further, as the setting information of the air mattress 100, the function of the air mattress 100 corresponding to the type of the bed in which the air mattress 100 is installed may be set. For example, in the case of a bed having a back-raising function, the internal pressure of the air cell 120 may be controlled according to the back-raising state. Further, in the case of a bed having a foot raising function, the internal pressure of the air cell 120 may be controlled according to the foot raising state.

The mode setting is an item for setting an operation mode such as a normal mode, a contracture mode, and a rest mode according to the state of the user.

The group ID is an identifier for classifying a plurality of users having the same setting of the air mat 100 into a plurality of groups, and is set in common with the plurality of users. For the group ID, for example, a value having a smaller number of digits than the identification information for identifying the individual user can be set.

In the external medium 300 or the external medium 310 (hereinafter collectively referred to as "external medium 300"), a group ID of a group in which users having the external medium are classified is set. For example, when an RFID tag used as a patient tag in an existing patient management system is used as the external medium 300, the group ID is set in a free area different from the area in which the identification information of the individual user is stored. Can be set.

The air mattress control device 200 acquires the group ID as user information from the external medium 300, and acquires the information of the internal pressure setting and the expansion / contraction setting associated with the acquired group ID from the storage 240. The air mattress control device 200 controls the air mattress 100 based on the internal pressure setting and the expansion / contraction setting acquired from the storage 240.

In this way, by setting the group ID and controlling the state of the air mattress 100 for each group, for example, when the patient tag used in the existing patient management system or the like is diverted to this system, each individual Even when the format of the user identification information varies and it is difficult to identify the user, the state of the air mattress 100 can be appropriately controlled. Further, since the value of the number of digits smaller than the identification information of the individual user can be set as the group ID, the amount of information stored in the storage 240 can be suppressed to a small amount, and the memory resource can be saved.

In the above embodiment, an example in which the setting information of the air mattress 100 is associated with the group ID and stored in the storage 240 has been described, but the present invention is not limited to this. Physical information and biological information may be associated with the group ID, and the state of the air mattress 100 may be controlled based on each information.

Further, in each of the above embodiments, an example in which the air supply unit 270 is integrally provided as a part of the air mattress control device 200 has been described, but the hardware configuration of the air mattress system is not limited to this. For example, the air mattress control device 200 and the air supply device may be provided as separate bodies and wirelessly connected to each other. That is, the external terminal 400 of FIG. 6 described in the third embodiment may be used as the air mattress control device 200, and may communicate with the air supply unit 270 provided as a separate device to control the state of the air mattress 100.
