It takes the structure connected via.

(System operation overview)
An outline of the operation of this system will be described next.

  In the configuration shown in FIG. 1, the bed control server includes “for medical personnel”, “for patient”, “for a person with a height of 180 cm or more”, and “for a person with a height of 150 cm or less” for each attribute of a person. Alternatively, an appropriate value of the state of the electric bed is registered for each individual such as “for XX doctor”, “for △△ nurse”, or for each combination thereof. The registered value of the electric bed state includes the height value of the electric bed, the angle of the backrest, and the like, which will be referred to as preset information. Note that the preset information may be information corresponding to the state of the electric bed, and may be, for example, the rotation angle from the reference value of the motor in the motor drive mechanism.

  The bed control server notifies preset information to the electric bed as necessary, and the electric bed sets the preset information. And based on the instruction | indication (for example, pressing down of a predetermined button (it calls a preset button)) in operation parts, such as a patient using an electric bed, an electric bed changes to the state corresponding to the preset information set.

(Detailed configuration of electric bed and bed control server)
Next, the electric bed and the bed control server will be described in more detail.

  The electric bed has preset information and an electric bed setting / control unit for controlling the motor drive mechanism.

(System operation details)
Hereinafter, the operation of the system according to the present embodiment will be described in detail.

[Register preset information]
In order to use this system, it is necessary to register preset information suitable for each patient or each medical staff in the bed control server. Examples of the registration method include the following methods. .

  When a height value suitable for a patient to get on and off the electric bed is known, the height value is stored in the database of the bed control server in association with the identification information of the patient. In addition, when values such as the bed height and backrest angle at which a specific doctor for a patient can easily examine the patient are known, these values are associated with the patient and the doctor as preset information. Stored in the bed control server database. The patient identification information may be identification information of an electric bed used by the patient.

  In addition, when the electric bed has a sensor function that detects the current bed height, the angle of the backrest, etc., the patient, medical personnel, etc. use the motor drive mechanism to To the desired state, and by pressing a predetermined button on the operation unit, an instruction to acquire information on the state is sent to the electric bed setting / control unit, and the electric bed setting / control unit responds to the instruction. Then, values indicating the current state (current bed height, backrest angle, etc.) are acquired from the sensor function. The patient or the like inputs a number or name (for example, for getting on and off) for identifying this state from the operation unit, and the state value (preset information) acquired from the sensor function by the electric bed setting / control unit The identification information of the patient or the electric bed and the name for identifying the state are transmitted to the bed control server. The bed control server registers the above information in the database.

  It is also possible to automatically register preset information without instructing by pressing a button as described above. For example, when a specific doctor for a patient manually places the electric bed in order to make it easier to examine the patient, the information on the state is associated with the doctor and the patient, It is automatically registered in the bed control server with the name "state". In order to register automatically, for example, the doctor may register with the bed control server after a certain period of time has elapsed since the doctor put the electric bed in a certain state. Note that identification of a specific doctor can be realized by a wireless tag or PHS described later.

  In the above example, the preset information is registered in the bed control server. However, the preset information acquired as described above may be registered in the preset recording database of the electric bed setting / control unit. The preset information recorded in the preset recording database is used for manual selection.

  Now, the operation of the system according to the present embodiment can be broadly divided into an operation when the user manually selects one of a plurality of preset information and an operation when the system automatically selects the preset information. There is a street. Hereinafter, each case will be described. Note that whether preset information is manually selected or automatically selected can be set by mode selection from the operation unit. Even in the automatic selection mode, if the preset information is manually selected, the manual selection may be prioritized.

[When selecting preset information manually]
Since the operation when manually selecting preset information is mainly executed by the electric bed setting / control unit, the operation will be described below with reference to the flowchart of FIG. 5 showing the operation of the electric bed setting / control unit.

  First, a patient requests display of preset information by pressing a predetermined button on the operation unit. The electric bed setting / control unit receives this display request from the operation unit (step 1), and confirms whether there is preset information in the preset recording database (step 2). If there is preset information, a name for identifying the preset information (for getting on and off, etc.), a number and the like are displayed on the display of the operation unit (step 3). If there is no preset information in the preset recording database, a preset information request including the identification information of the electric bed is transmitted to the bed control server, and the preset information corresponding to the electric bed is received from the bed control server together with its name (step 4). When the bed control server manages preset information in association with the patient identifier, a preset information request including the patient identification information is transmitted to the bed control server, and the bed control server Preset information corresponding to a patient may be acquired. The acquired preset information is stored and displayed in the preset recording database.

  FIG. 6 shows an example of preset information stored in the preset recording database. In FIG. 6, the rotation angle based on a certain initial value of each motor is recorded as the pro-set information in the preset recording database. This is information obtained by converting the preset information including the bed height value and the backrest angle received from the bed control server into the rotation angle of the motor by the preset information access function. Instead of recording the rotation angle of the motor as preset information in the preset recording database as described above, the value of the bed height, the angle of the backrest, etc. may be recorded as preset information in the preset recording database.

  Subsequently, the patient selects desired preset information from the displayed preset information on the operation unit. For example, the selection is performed by inputting a number corresponding to the preset information to the operation unit.

  The electric bed setting / control unit that has received information such as a number indicating the selected preset information acquires preset information corresponding to the information from the preset recording database and notifies the motor control function (steps 5 and 6). ). Thereafter, when the preset button is pressed in the operation unit (step 7), the motor control function operates the motor drive mechanism to shift the electric bed to a state corresponding to the preset information (step 8).

  Although the bed control server is used in the above example, the bed control server may not be used by registering preset information directly in the electric bed setting / control unit.

[When selecting preset information automatically]
When automatically selecting preset information, preset information is selected with a certain situation as a trigger. As the situation, three examples will be described: (1) medical personnel (doctors, nurses, etc.) are present in the room, (2) arrival of time, and (3) pressing a nurse call.
(1) When a medical person exists in a hospital room as a trigger As a method for detecting whether or not a medical person exists, there are, for example, a method using a wireless tag and a method using PHS.

A) Example of using a wireless tag An example of using a wireless tag will be described taking the system configuration shown in FIG. 7 as an example. When the wireless tag is used, a reader 50 that detects the wireless tag ID is provided at the entrance of the hospital room. In addition, each medical person holds a wireless tag 52 that transmits an ID corresponding to each medical person.

  In the configuration of FIG. 7, there are two electric beds in one hospital room. A reader ID is assigned to the reader 50, and each IP address is assigned to the electric bed setting / control unit of each electric bed. The reader, each electric bed, and the bed control server can be connected via a hospital LAN.

  The database in the bed control server stores tables 1 to 3 shown in FIGS. 8A, 8B, and 8C. The table 1 stores information on the reader ID, the room number, and the IP address of the electric bed. The table 2 stores tag IDs and preset information for medical personnel who hold the tag IDs. The table 3 stores a tag ID and a priority for the tag ID for each bed number. Although not shown, it is assumed that preset information for getting on and off for each electric bed is stored in the database in the bed control server. Moreover, in the table 2 of FIG.8 (b), you may store preset information about each tag ID for every electric bed. Thereby, even if it is the same medical staff, it becomes possible to set it as a different state for every patient. Further, in the table 3, instead of providing a priority order for each electric bed, a common priority order may be provided for a plurality of electric beds.

  Next, the operation of the bed control server will be described with reference to the flowchart of FIG.

  The bed control server is initially in a state of waiting for information from the reader (step 11). When the tag ID and the reader ID are received from the reader (step 12), the bed control server refers to the table 3 in FIG. 8 and selects the tag ID to be applied for each bed (step 13). That is, when the two medical personnel who entered the room correspond to the tag ID of A and the tag ID of B, respectively, the tag ID of A is applied to the electric bed 1 and B is applied to the electric bed 2. The tag ID is applied. In addition, for example, when there is one medical person who entered the room and it is A, the tag ID of A is applied to both of the electric beds 1 and 2, but when the tag ID is C, it is applied. Since there is no tag ID to be performed, the process returns to the standby state.

  Subsequently, the bed control server refers to the table 2 in FIG. 8 and acquires each preset information corresponding to the tag ID to be applied (step 14). Then, referring to Table 1, an IP address for each bed number corresponding to the reader ID is acquired (step 15), and preset information applied to the bed number corresponding to the IP address is transmitted to the IP address. (Step 16). The transmission information at this time may include an instruction to notify the preset information to the motor control function in the electric bed setting / control unit. By this instruction, the electric bed setting / control section can determine that the received information should be immediately notified to the motor control function, instead of storing the received information in the preset recording database.

  On the electric bed side, the electric bed is changed to a state corresponding to the preset information in accordance with depression of the preset button in the same manner as steps 6 to 8 in FIG.

  After that, the bed control server monitors whether or not the tag ID is transmitted from the corresponding reader, and determines that the medical staff has left the room by detecting that the tag ID is not transmitted for a certain period of time. (No in step 17). Thereafter, for example, preset information for getting in and out of the electric bed is transmitted (step 18). Thereby, the user of the electric bed can get on and off the electric bed only by operating the preset button after the medical staff leaves the room.

A) Example of using PHS Next, a case of using PHS will be described taking the system configuration shown in FIG. 10 as an example. As shown in FIG. 10, when using PHS, a PHS base station 60 is provided in a hospital room. In addition, each medical person holds a PHS 62 that transmits a machine ID corresponding to each medical person.

  In the configuration example of FIG. 10, one electric bed exists in one hospital room. A base station ID is assigned to the PHS base station, and an IP address is assigned to the electric bed setting / control unit of the electric bed. The PHS base station, the electric bed, the PBX, and the bed control server can be connected via a hospital LAN. The PBX 64 receives and holds the base station ID and the PHS machine ID transmitted from the PHS base station, and uses the base station ID and the PHS machine ID for bed control in response to an information inquiry from the bed control server. It has a function to send to the server.

  Further, tables 1 to 3 shown in FIGS. 11A, 11B, and 11C are stored in the database in the bed control server. Table 1 stores information on base station ID, hospital room number, and IP address of the electric bed. The table 2 stores preset information for medical personnel that holds the machine ID and the PHS of the machine ID. The table 3 stores the machine ID and the priority for the machine ID. Although not shown, it is assumed that preset information for getting on and off for each electric bed is stored in the database in the bed control server. The operation of the bed control server in the configuration of FIG. 10 will be described with reference to the flowchart of FIG.

  The bed control server periodically inquires of the PBX whether or not the information on the aircraft ID has been acquired for each base station ID (step 21). If the information of the machine ID in the corresponding base station ID exists in the PBX, the information is acquired (step 22). After that, the bed control server refers to the table 3 in FIG. 12 and selects the aircraft ID to be applied (step 23). That is, for example, when two medical personnel who have entered the room correspond to the aircraft ID of A and the aircraft ID of B, respectively, the aircraft ID of A is applied. Further, for example, when there is one medical person who enters the room and the machine ID is B, the tag ID B is applied.

  Subsequently, the bed control server refers to the table 2 in FIG. 11 and acquires preset information corresponding to the aircraft ID to be applied (step 24). Then, referring to Table 1, the IP address of the electric bed corresponding to the base station ID is acquired (step 25), and preset information applied to the electric bed corresponding to the IP address is transmitted to the IP address. (Step 26). The transmission information at this time may include an instruction to notify the preset information to the motor control function in the electric bed setting / control unit. By this instruction, the electric bed setting / control section can determine that the received information should be immediately notified to the motor control function, instead of storing the received information in the preset recording database.

  On the electric bed side, the electric bed is changed to a state corresponding to the preset information in accordance with depression of the preset button in the same manner as steps 6 to 8 in FIG.

Thereafter, the bed control server monitors whether or not the aircraft ID is transmitted from the corresponding base station by accessing the PBX, and detects that no aircraft ID is transmitted for a certain period of time. It is determined that the person concerned has left the room (No in step 27), and, for example, preset information for getting on and off is transmitted to the corresponding electric bed (step 28).
(2) When Time is Triggered Next, a case where preset information is automatically selected using time as a trigger will be described. In this case, the bed control server stores tables 1 and 2 as shown in FIGS. 13A and 13B in the database. This table 1 stores identification information (name etc.) of preset information corresponding to the situation at each specific time such as a wake-up time. The table 2 stores preset information corresponding to the identification information of the preset information for each bed. Although not shown, it is assumed that the IP address of each electric bed is recorded in the table 3.

  The bed control server monitors the timer held by itself, and when it is detected that the time recorded in the table 1 of FIG. 13 is reached, acquires the identification information of the preset information corresponding to the time, Using the tables 2 and 3, preset information of each electric bed corresponding to the identification information is transmitted to each electric bed.

Furthermore, by using the above function, it is possible to automatically set preset information corresponding to the doctor in charge on the day at all beds in the ward at the morning roundabout time.
(3) When the trigger is that the nurse call is pressed In this case, the system is configured so that the bed control server is notified that the nurse call button has been pressed. For example, when a center device of a nurse call system is connected to a LAN and the nurse call button is pressed, the center device has a function to notify the bed control server of the nurse call button press information and the electric bed identification information. Prepare.

  As shown in FIG. 14, the bed control server holds preset information for medical personnel who are likely to rush to a specific electric bed (patient) when receiving a nurse call for each electric bed. Keep it. When the bed control server receives information indicating that the nurse call button has been pressed in a certain electric bed, the bed control server refers to the table in FIG. The preset information for the person is transmitted to the electric bed. In the electric bed, the electric bed setting / control unit passes the preset information to the motor control function. Then, in response to pressing of the preset button, the electric bed changes to a state corresponding to the preset information. In this example, it can be said that the state of the electric bed is predicted based on a certain situation.

  In the above examples (1) to (3), the bed control server is used. However, by providing the bed control server function in the electric bed setting / control unit, the bed control server can be preset without using the bed control server. It is also possible to automatically select information. That is, in this case, a means for detecting a predetermined trigger in the electric bed, a preset information selecting section for selecting preset information corresponding to the trigger from the preset recording database when the trigger is detected, and the preset information selection After the preset information is selected by the means, when receiving an instruction to change the state of the movable part, the movable part is made to correspond to the selected preset information by controlling the driving means. Control means for changing to a state.

  In all the above examples, the electric bed setting / control unit is not necessarily provided in the electric bed.

  As described above, according to the embodiment of the present invention, since the medical staff can perform nursing care in the state of the bed that is always easy to care without performing extra work such as height adjustment of the bed, The physical burden on medical personnel is reduced. In addition, for example, it is possible to obtain an environment in which the patient can easily get on and off the bed without performing extra work such as adjusting the height of the bed. As a result, patient independence can be supported, and accidents that occur when getting on and off the bed can be reduced.

  The present invention is not limited to the above-described embodiment, and various modifications and applications can be made within the scope of the claims.
