Description

  The present invention relates to a nurse call system for a medical worker in the vicinity of a patient's bed to request support from another medical worker.

  In general, a nurse call system is used in hospitals and care facilities. The nurse call system is used when a patient admitted to a hospital needs assistance from a nurse or when a cared person in a care facility needs assistance from a caregiver. A care recipient (hereinafter collectively referred to as a patient) can call a nurse or caregiver (hereinafter collectively referred to as a health care worker) by operating the call operation unit. It is a system that has been made.

  Many nurse call systems are installed in the vicinity of beds in hospital rooms, toilets, bathrooms, etc., and are installed in nurse call cordless handsets with button-like call operation units and nurse stations where medical workers are stationed. The nurse call master unit that alerts you to the call and is installed on the corridor near the entrance of each room such as a hospital room or nursing room (hereinafter collectively referred to as a hospital room) and displays the names of patients in the hospital room Or a corridor lamp that displays that a patient in a hospital room is calling, and a controller that performs control related to call and data transmission / reception. In addition to the above-described configuration, a nurse call system including a portable terminal such as a PHS (Personal Handy phone System) terminal carried by a medical worker and a PBX (Private Branch Exchange) is also provided.

  In such a nurse call system, when the call operation unit of the nurse call slave unit is operated, the call signal generated by the nurse call slave unit is output to the nurse call master unit via the corridor lamp. The nurse call parent device or mobile terminal notifies the patient that the call has been made by voice or the like, and displays information on the display for identifying the patient who made the call (actually, the bed number including the room number). To display. A medical worker who has grasped the notification can respond to the call by off-hooking the handset installed in the nurse call master unit or off-hooking the portable terminal he / she carries. . Here, when a response is made to the call, the notification performed on the nurse call parent device or the portable terminal stops.

  The medical worker who made the response goes to the hospital room where the patient who operated the call operation unit of the nurse call slave (in other words, the patient who made the call) and checked the patient's condition. However, a medical worker who goes to a hospital room where the patient is present may not be able to handle the patient. This may be the case when the patient's condition is changing suddenly. In addition, the patient's solution may suddenly change while the medical worker is patroling regardless of the call by the nurse call slave.

  In any of the cases described above, the medical staff operates the nurse call slave unit or a staff call operation unit (also referred to as an emergency call operation unit) provided in the vicinity of the nurse call slave unit. Then, a staff call signal is generated by the staff call operation unit and is output to the nurse call master unit. The nurse call parent device or mobile terminal informs by voice that a call requesting the support of another medical worker has been made by a medical worker, and also indicates the place where the call was made (actually the room number) The information for specifying the bed number (including the bed number) is displayed on the display. Other medical workers who have grasped this notification can respond to the call by off-hooking the handset installed in the nurse call master unit or off-hooking the portable terminal carried by themselves. . Here again, when a response is made to the call, the notification performed on the nurse call parent device or the portable terminal stops.

  By the way, when the patient's condition is changing suddenly, in order to avoid life-saving treatment when there is another patient in the patient's room, move the patient who has changed suddenly to an empty room. There are cases where lifesaving treatment is performed. In this case, since the medical staff moves the patient to an empty room after operating the staff call operation unit, there is a problem that the medical staff who came to support cannot know which room to go to. It was. On the other hand, if a health care worker moves a patient to an empty room and then operates the staff call operation section of that room, the staff call is made after the health care worker has completely entered the empty room. As a result, the staff call was delayed.

  In order to solve such a problem, the following technique is known (see Patent Document 1). In the technique described in Patent Document 1, hospital room information indicating the number of patients in a hospital room and the number of patients admitted to the hospital room is stored for each patient room, a wireless transmitter is attached to the bed, and the wireless transmitter is installed in the hospital room. A wireless reading device that reads radio signals when passing through the entrance / exit is installed near the entrance / exit, and the wireless reading device reads the radio signal at the entrance / exit of a hospital room with two or more hospitalized patients. After that, when the wireless reading device of the hospital room where the patient who is hospitalized with the wireless signal from the same wireless transmitter reads zero, the hospital room requests that other medical personnel be supported. The nurse call parent machine is informed.

JP 2014-161467 A

  However, in the above-described prior art, the radio signal from the same radio transmitter is hospitalized after the radio reader reads the radio signal at the entrance and exit of a hospital room where the number of patients in the room and the number of hospitalized patients are two or more. When the wireless reading device in the hospital room where the patient is zero reads, the nurse call parent device informs that the patient is requesting the support of another medical worker in the hospital room. Even if the bed is moved to a hospital room where the number of patients in the room and the number of hospitalized patients from two or more hospital rooms is zero, the staff call will be notified and a false alarm will occur. There was a problem that.

  The present invention has been made to solve such a problem. When the patient's condition is suddenly changed, the patient is emptied when there is another patient in the patient's room. The purpose is to be able to appropriately call the support of other medical professionals.

  In order to solve the above-described problems, in the present invention, hospital room information indicating the number of patients in a hospital room and the number of patients hospitalized in the hospital room is stored for each patient room, a wireless transmitter is attached to the bed, and the vicinity of the bed is installed. A staff call operation unit for calling other medical personnel is attached. In addition, a wireless reading device that reads a wireless signal when the wireless transmitter passes through the entrance / exit of the hospital room is attached in the vicinity of the entrance / exit. Then, after the staff call operation unit is operated and the wireless reader reads the wireless signal at the entrance and exit of the hospital room where the number of hospital rooms and the number of hospitalized patients are two or more, the wireless signal from the same wireless transmitter is received. When the wireless reading device of another hospital room reads it, the nurse call parent machine will notify that the hospital room that has received the wireless signal from the wireless transmitter later requests the support of another medical worker. I have to.

  According to the present invention configured as described above, when a bed is moved from a hospital room where another patient is present to a patient room where there is no other patient, and the staff call operation unit is operated before the movement is performed. Because the nurse call parent device will notify you of the support of other medical personnel, in addition to the patient whose condition has suddenly changed, when moving the patient from bed to room where the patient is vacant In addition, it is possible to appropriately request the support of other medical staff.

It is a figure which shows the example of installation of the nurse call system by this embodiment. It is a block diagram which shows the structural example of the nurse call system by this embodiment. It is a figure which shows the example of the memory content of the memory | storage part of a nurse call parent machine. It is a figure which shows the operation example of the movement of the patient by this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a diagram illustrating an installation example of the nurse call system according to the present embodiment, and FIG. 2 is a block diagram illustrating a configuration example of the nurse call system according to the present embodiment. In FIG. 1, four beds are installed in the first hospital room, and three of them are used by hospitalized patients. The remaining floor is an empty bed. A wall unit is provided on the wall surface in the vicinity of each bed, and a wired nurse call cordless handset is connected to the wall unit. The nurse call cordless handset is provided with a call operation unit 10 that is operated by a patient to call a medical worker. The wall unit is also provided with a staff call operation unit 12 that is operated when a medical worker requests support from another medical worker. In addition, a wireless transmitter 30 is attached to the bed, and a wireless reader 20 is installed in the vicinity of the entrance of the hospital room.

  In FIG. 2, reference numeral 1 denotes a nurse call parent device, which is installed in a nurse station where a medical worker resides. In addition, you may make it use the portable terminal which a medical worker carries as the nurse call main | base station 1. FIG. Here, the nurse call parent device 1 includes a control unit 2, a notification unit 3, a storage unit 4, and a parent device interface 5.

  The interface 11 is installed in each hospital room, and connects the call operation unit 10 of the nurse call slave unit, the staff call operation unit 12 of the wall unit, and the wireless reading device 20 to the nurse call master unit 1. In addition to communicating, it controls each connected device. Here, the above-described devices (call operation unit 10, staff call operation unit 12, and wireless reading device 20) are also installed in other hospital rooms such as the second hospital room. The interface 11 includes a timer (not shown).

  When the call operation unit 10 is operated by the patient, the interface 11 generates a call signal. At this time, the call signal includes handset identification information for identifying the call operation unit 10 (actually a nurse call handset) from other call operation units 10.

  Further, when the staff call operation unit 12 is operated by the medical staff, the interface 11 generates a staff call signal. At this time, the stuff call signal includes handset identification information for identifying the stuff call operation unit 12 (actually a nurse call handset) from other stuff call operation units 12. Here, as the slave unit identification information, a bed number (determined by the number of the hospital room and the serial number of the bed in the hospital room) or the like is used.

  Next, each component of the nurse call parent device 1 will be described. The control unit 2 is for controlling each component of the nurse call master device 1 as described later, and is configured by a CPU (Central Processing Unit) or the like.

  The notification unit 3 is configured by a speaker, a display, and the like, and a voice and display that the patient is calling a medical worker and that the medical worker is requesting support from another medical worker. It is for informing. Here, the alerting | reporting part 3 needs to change the alerting | reporting pattern of alerting | reporting which shows the call from a patient, and alerting | reporting which shows the request | requirement of the support from a medical worker. The notification content of the notification unit 3 includes handset identification information indicating the patient who is calling (actually a bed number or the like).

  The storage unit 4 stores, for each hospital room, hospital room information indicating the number of hospital rooms and the number of patients currently admitted to the hospital room in association with the room identification information (see FIG. 3). Here, the hospital room information stored in the storage unit 4 is updated as the patient enters and leaves the hospital, the bed moves, and the like. When the number of sickrooms is 1, the sickroom is a private room, and when the sickroom capacity is 2 or more, the sickroom is a multi-bed room. Also, the number of patients currently admitted to the room will not exceed the capacity. When the number of hospitalized patients is 0, the room is vacant. The room identification information is for identifying each room so as to be specified, and is determined by the room number. Here, the hospital room number constitutes a part of the bed number described above.

  In the example shown in FIG. 3, the capacity of the first hospital room is 4, and the number of patients currently hospitalized in the first hospital room is 3. Moreover, the capacity of the second hospital room is 2, and the number of patients currently hospitalized in the second hospital room is 0. Similarly, the capacity of each hospital room and the number of patients currently hospitalized are stored in the storage unit 4.

  The master unit interface 5 is used for communication by connecting the nurse call master unit 1 and the interface 11 installed in each hospital room. The base unit interface 5 receives a call signal generated by the call operation unit 10, a stuff call signal generated by the stuff call operation unit 12, and a radio signal generated by the wireless reading device 20 described later.

  When the wireless transmitter 30 approaches the reading range of the wireless reader 20, power is supplied to transmit a wireless signal. This wireless signal includes slave unit identification information (for example, a bed number) for identifying the bed to which the wireless transmitter 30 is attached from other beds. In addition, the subunit | mobile_unit identification information of the radio transmitter 30, the staff call operation part 12, and the call operation part 10 installed in the same bed becomes the same.

  The wireless reader 20 reads a wireless signal transmitted from the wireless transmitter 30 that has approached the reading range. Here, it is preferable that the wireless reader 20 reads a wireless signal from the wireless transmitter 30 that has passed through the entrance of the hospital room. Further, the wireless reading device 20 that has read the wireless signal adds the room identification information for identifying the hospital room in which the wireless reading device 20 is installed to the wireless signal, and the nurse call parent device 1 through the interface 11. Output to.

  Next, the operation of the nurse call system configured as described above will be described with reference to FIGS. The medical worker responds to the notification performed by the notification unit 3 of the nurse call master unit 1 when the call operation unit 10 of the nurse call slave unit is operated, so that the patient's hospital room (first hospital room) can respond. Ask. In addition, the visit of a medical worker to a hospital room is not limited to this, and includes cases where a medical worker patrols.

  If the patient's condition changes suddenly while the medical worker is in the first hospital room, the medical worker operates the staff call operation unit 12. Then, a timer provided in the interface 11 starts operating. Then, the medical worker moves the patient out of the first room with the bed. When the bed passes through the entrance / exit of the first hospital room, power is supplied to the wireless transmitter 30 attached to the bed, and the wireless transmitter 30 transmits a wireless signal (state shown in FIG. 4A).

  Here, when the wireless reader 20 reads a wireless signal in a state where the time measured by the timer is within a predetermined time (for example, within 30 seconds), the slave unit identification information included in the wireless signal; The interface 11 determines whether or not the slave unit identification information included in the staff call signal generated when the staff call operation unit 12 is operated matches. When the interface 11 determines that the two match, the interface 11 outputs the radio signal input from the radio reader 20 to the nurse call parent device 1. On the other hand, if the interface 11 determines that the two do not match, the interface 11 does not output a radio signal to the nurse call master unit 1 simply because the bed movement has been performed.

  Further, when the interface 11 does not input a wireless signal from the wireless reading device 20 even when the time measured by the timer is equal to or longer than a predetermined time (in other words, the wireless reading device 20 reads a wireless signal from the wireless transmitter 30). If not, the interface 11 outputs a staff call signal to the nurse call master unit 1 as if the staff call operation unit 12 was simply operated. And the alerting | reporting part 3 of the nurse call main | base station 1 alert | reports that the medical worker is requesting the support of another medical worker. At this time, the handset identification information included in the staff call signal is that of the nurse call handset installed in the first hospital room.

  When the interface 5 of the nurse call parent device 1 inputs a wireless signal, the control unit 2 extracts the child device identification information and the room identification information included in the wireless signal, and extracts them by referring to the storage unit 4. Based on the room information stored in association with the room identification information, it is determined whether the number of patients in the room and the number of patients hospitalized in the room are two or more.

  When the number of hospital rooms and the number of hospitalized patients are both 2 or more, the wireless reading device 20 installed in another hospital room includes a wireless signal including the same child device identification information as the extracted child device identification information. It is determined whether or not the input has been made.

  On the other hand, if the hospital room is a private room or there are no other hospitalized patients, the capacity of the hospital room and the number of hospitalized patients are both 1. This corresponds to a case where the patient in the hospital room is moved with the bed for reasons other than a sudden change in the condition, or a case where only the bed in the hospital room is carried out of the hospital room. When there are no inpatients in the hospital room, the number of hospitalized patients is zero. This corresponds to the case where only the bed in the sickroom is carried out of the sickroom. In these cases, the control unit 2 ends the process.

  The health care worker who moved the patient with the bed out of the first room brings the patient into a single room or a second room without inpatients. When the bed passes through the entrance / exit of the second hospital room, power is supplied to the wireless transmitter 30 attached to the bed, and the wireless transmitter 30 transmits a wireless signal (see, for example, FIG. 4B). . Since the slave unit identification information included in the wireless signal is the same as the slave unit identification information included in the wireless signal input to the master unit interface 5 earlier, the same slave unit identification information as the extracted slave unit identification information is used. The control unit 2 determines that the included wireless signal is input from the wireless reading device 20 installed in the second hospital room.

  Then, the control unit 2 refers to the storage unit 4 and extracts the room identification information included in the wireless signal input from the wireless reading device 20 installed in the second hospital room. And the control part 2 makes the alerting | reporting part 3 alert | report that the medical worker has requested | required the support of another medical worker, after specifying a hospital room by hospital room identification information. Other medical workers who have grasped this notification will go to the hospital room of the destination and provide support.

  Here, if the slave unit identification information does not match, the wireless signal including the slave unit identification information is transmitted from the wireless transmitter 30 attached to another bed, so that determination and control are separately performed. Done.

  As described above in detail, according to the present embodiment, the room information indicating the number of patients in the room and the number of patients admitted to the room is stored for each room, the wireless transmitter 30 is attached to the bed, A staff call operation unit 12 for calling other medical personnel is attached in the vicinity. In addition, a wireless reading device 20 that reads a wireless signal when the wireless transmitter 30 passes through the entrance of the hospital room is attached in the vicinity of the entrance. Then, after the staff calling operation unit 12 is operated and the radio reader 20 reads the radio signal at the entrance / exit of the hospital room where the number of hospital rooms is equal to or more than two patients, the same radio transmitter 30 When the wireless reading device 20 of another hospital room reads the wireless signal, the nurse call parent that requests the support of other medical workers in the hospital room that received the wireless signal from the wireless transmitter 30 later. The machine 1 is informed.

  As a result, when a bed moves from a hospital room where other patients will be located to a hospital room where there are no other patients, and the staff call operation unit is operated before moving, the support of other medical staff is supported. The nurse call master unit 1 provides the requested notification, so that in addition to the patient whose condition is changing suddenly, other medical workers should be properly engaged when moving the patient from the patient room where the patient is located to the vacant room. You can ask for support.

  In the above-described embodiment, the staff call operation unit 12 is configured such that when the bed leaves the hospital room within a predetermined time measured by the timer of the interface 11, the place where the other medical staff should go is the destination of the bed. If it is determined that the patient is in a hospital room and the time measured by the timer of the interface 11 has passed a predetermined time without leaving the patient room, it is determined that the place where other medical personnel should go is the patient room. However, it is not limited to this. For example, a staff call operation unit for requesting support for the patient room and a staff call operation unit for requesting support for another patient room may be provided separately.

  In the above-described embodiment, a medical worker who carries a bed out of a hospital room looks for a vacant hospital room visually, but the present invention is not limited to this. For example, a display device may be attached on the flow line of the bed, and hospital room identification information of a hospital room in which the number of patients hospitalized is zero may be displayed on this display device as hospital room information. Here, the flow line of the bed may be a corridor or an entrance / exit of a hospital room. Further, a display device may be attached to the bed.

  Further, in the above-described embodiment, the nurse call parent device 1 performs notification when the bed is moved to the destination hospital room, but is not limited thereto. For example, the nurse call parent device 1 may notify the user when the staff call operation unit 12 is operated or when the bed leaves the moving room. Here, since the information about the location of the destination hospital room is specified when the bed enters the destination hospital room, when the staff call operation unit 12 is operated, or when the bed leaves the source hospital room. At that time, the notification unit 3 notifies the child device identification information associated with the bed and that the support of another medical worker is requested. And the display of the place where another medical worker should go is performed when the bed enters the destination hospital room.

  In addition, the said embodiment is only what showed the example in implementation in implementing this invention, and, as a result, the technical scope of this invention should not be interpreted limitedly. In other words, the present invention can be implemented in various forms without departing from the spirit or main features thereof.
