FIG. The external medium 300 is a medium external to the air mattress control device 200, such as a name tag or tag attached to the user. The air mattress control device 200 acquires user information from the external medium 300 owned by the user, and controls the state of the air mattress 100 according to the user based on the acquired user information. Each configuration will be described in detail below.

<Air mattress 100>
The air mattress 100 is, for example, placed on a bed mattress 110 and configured by arranging a plurality of bag-like air cells 120 extending in the lateral direction of the bed mattress 110 in the longitudinal direction of the bed mattress 110 . The air mattress 100 has a plurality of independent air supply systems. A different blower tube is connected to each air supply system, and air is supplied to each air supply system independently. Each air cell 120 is connected to one of a plurality of air supply systems, and the internal pressure is controlled for each air supply system. Each air cell 120 may be divided into a plurality of groups, and each air cell 120 may communicate with each other for each group.

For example, in the example shown in FIG. 1, the air mattress 100 has three air supply systems. Each air cell 120 is sequentially divided into three groups in the order in which they are arranged, and the air cells 120 within each group are communicated with each other. Each group is connected to three air supply systems respectively. By periodically changing the internal pressure settings of the three air supply systems, the air cells 120 connected to the respective air supply systems are cyclically expanded and contracted, and the air mattress 100 can be waved. As a result, the air cell 120 that contacts the user can be periodically changed, and the stuffiness and pressure caused by the same air cell 120 continuously contacting the user for a long period of time can be prevented, thereby suppressing the occurrence of bedsores. The type, shape, number, arrangement, etc. of the air cells 120 are not limited to the example shown in FIG. 1, and the air cells 120 may be used in any manner. Also, the number of air supply systems, the connection method of the air cells 120, and the like are not limited to the above examples.

<Information Stored in Storage 240>
FIG. 3 is a diagram showing an example of information stored in the storage of the air mattress control device.

As shown in FIG. 3, in the storage 240 of the air mattress control device 200, for example, information such as user identification information, name, height, weight, state, internal pressure setting, inflation/deflation cycle setting, etc. are stored in association with each other. It is

The identification information is information for identifying a user, and is unique information within the system represented by, for example, alphanumeric characters and symbols. As the identification information, for example, a patient ID given to each patient in a hospital patient management system can be used.

The name is the name of the user, etc., and is used as information for identifying the user in the same manner as the identification information described above. Further, for example, the name may be displayed on the display operation unit 250 of the air mattress control device 200 to be confirmed by the user, and used to detect errors in patient tag attachment, information registration errors, and the like. In addition to the name, the user's age, date of birth, information about the user's face and voice, etc. may be recorded, and the air mattress control device 200 uses each information to identify the user. , can be authenticated.

Height and weight are physical information of the user and are used to optimally control the state of the air mattress 100 according to the user. For example, the air mattress control device 200 may calculate the optimum internal pressure of the air mattress 100 according to the weight of the user and control the internal pressure of the air mattress 100 . Alternatively, the air mattress control device 200 may determine the body shape of the user based on the weight and height of the user, and control the internal pressure of the air mattress 100 and the variation of the internal pressure according to the body shape.

The state is biometric information indicating information about symptoms, chronic diseases, etc. of the user, and is used to optimally control the state of the air mattress 100 according to the user. For example, in the example of FIG. 3, it is shown that "Mr. B" and "Mr. D" have symptoms of contracture. When contracture occurs, the user's body bends and the area in contact with the air mattress 100 becomes smaller, increasing the pressure. As a result, the air mattress 100 sinks excessively and bottoms out, making bedsores and the like more likely to occur. In order to prevent this, by setting the internal pressure of the air mattress 100 higher than usual when there is a symptom of contracture, the user's posture can be stabilized and pressure concentration can be prevented. Also, it is shown that "Mr. E" is in a state requiring "rest". When the user is in a state that requires rest, the amount of movement of the user can be reduced and the rest can be maintained by setting a long expansion/contraction cycle or setting a small degree of fluctuation of the internal pressure. As biological information, for example, information relating to body temperature, blood pressure, heart rate, etc. may be stored and used to optimally control the state of air mattress 100 . For example, the air mattress control device 200 controls the temperature adjustment means and air blowing means of the air mattress 100 based on the information about the body temperature of the user to adjust the surface temperature of the air mattress 100 and the sensible temperature of the user. You can make it comfortable.

The internal pressure setting and the inflation/deflation cycle setting are setting information of the air mattress 100, and optimal setting values for each user are stored in advance. The internal pressure setting is a set value of the internal pressure of the air cell 120 . In the example of FIG. 3, values of 14 to 22 mmHg are registered as internal pressure settings. A plurality of internal pressure setting values may be provided so that the internal pressure can be set for each air supply system. The inflation/deflation cycle setting indicates the time cycle when the air cells 120 connected to each air supply system are cyclically inflated and deflated. 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 user's back-raising state may be stored. Also, as setting information of the air mattress 100, information for managing the internal pressure in each mode set according to the state of the user, such as a back-raised mode corresponding to the back-raised state and a contracture mode corresponding to the contracture state. may be registered. Furthermore, as the setting information of the air mattress 100, the function of the air mattress 100 corresponding to the type of bed on 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 leg lifting function, the internal pressure of the air cell 120 may be controlled according to the leg lifting state.

For example, the air mattress control device 200 and the air supply device may be separately provided 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 to communicate with the air supply unit 270 provided as a separate device to control the state of the air mattress 100 .

Moreover, although each of the above embodiments has been described as an independent embodiment, each embodiment may be combined with each other and carried out. For example, by combining the third to fifth embodiments, the external terminal 400 acquires the group ID from the external medium 300, acquires setting information associated with the group ID from the server 500, and controls the state of the air mattress 100. may be in any form.

In addition, each processing unit in the flowchart described above is divided according to the main processing contents in order to facilitate understanding of the processing of the air mattress control device 200 . The method of classifying the processing steps and their names do not limit the present invention. The processing performed by the air mattress control device 200 can also be divided into more processing steps. Also, one processing step may perform more processing.
