When a radio reader 20 of a sickroom which has no patient reads a radio signal from a radio transmitter 10 after a radio reader 20 reads the radio signal at the doorway of a sickroom whose capacity and the number of patients are two or more patients, a notification section 3 notifies request for assistance of another medical worker in the sickroom. Thereby, another notification is performed at the timing when the bed is brought into the sickroom of destination, and assistance of another medical worker can be requested as soon as possible.

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 at a hospital needs assistance from a nurse or when a care recipient at a care facility needs support from a caregiver (hereinafter referred to as “caregiver”). This system is configured so that a nurse or a caregiver (hereinafter collectively referred to as a medical worker) can be called by operating a call operation unit.

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 portable terminal such as a PHS (Personal Handy phone System) terminal carried by a medical worker and a PBX (Private
There is also a nurse call system with Branch Exchange.

  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 the mobile terminal notifies the patient that the call has been made by voice or the like. 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, there is a possibility that the patient's solution suddenly changes while the health care worker is traveling, regardless of the call by the nurse call cordless handset.

  In any case described above, the medical staff operates the nurse call slave unit or the staff 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. In the nurse call parent device or the portable terminal, it is notified by voice or the like that a call from a medical worker requesting the support of another medical worker has been made. 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.

  In addition, in order to prevent the staff calling operation unit for calling other medical workers from being erroneously operated by the patient, the medical worker is provided with a tag, and the tag reader provided in the nurse call slave unit reads the tag. A technique is known that calls other medical personnel only in the case of (for example, see Patent Document 1).

  By the way, when the patient's condition is suddenly changed, if there is another patient in the room, the patient who has caused the sudden change should be vacated to avoid performing lifesaving treatment in front of the other patient. There are cases where life-saving treatment is performed after moving to a hospital room. In this case, if a medical worker moves the patient to an empty room after operating the staff call operation unit, the medical staff who came to support will not know which room to go to There was a problem. 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, a technique (for example, refer to Patent Document 2) for detecting that the emergency medical device has been moved from a predetermined location and notifying the nurse call parent device or the portable terminal is applied to the bed. By doing so, when the movement of the bed is detected, the nurse call parent device or the portable terminal can be notified. Here, by attaching a wireless transmitter to the bed and attaching a wireless receiver to the entrance / exit of the hospital room, it is possible to detect that the bed has entered the hospital room, and call the staff when the bed enters the hospital room Can do.

JP 2006-325784 A JP 2008-113182 A

  However, since the wireless transmitter is attached to the bed in the above-described prior art, the staff is called even when the bed is simply moved (for example, when a bed not used in one hospital room is moved to another hospital room). There has been a problem that a false alarm occurs. In addition, it is possible to attach a wireless transmitter to the patient, but in that case, when the patient enters another room by himself, the staff call is notified, and there is a problem that a false alarm occurs. there were.

  The present invention has been made to solve such problems. When the patient's condition is changing suddenly, when there is a patient other than the patient, the patient is placed in an empty room. The purpose is to be able to call the support of other medical professionals as soon as possible.

  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 admitted to the hospital room is stored for each patient room, and a wireless transmitter is attached to the bed. A wireless reading device that reads a wireless signal when passing through the entrance / exit of a hospital room is attached in the vicinity of the entrance / exit. And after the wireless reader reads the wireless signal at the entrance and exit of a hospital room where the number of patients in the room and the number of hospitalized patients is two or more, the number of patients hospitalized with the wireless signal from the same wireless transmitter is zero. When a wireless reading device in a hospital room reads, the nurse call parent device notifies that the medical room is requesting the support of another medical worker.

  According to another aspect of the present invention, in addition to the above-described configuration, a patient wireless transmitter is attached to the patient, and the wireless reader reads the wireless signal transmitted from the wireless transmitter within a predetermined time. When a patient radio signal is read from a radio transmitter for a patient, the nurse call parent device notifies the request of support from another medical worker.

  According to another aspect of the present invention, in any of the above-described aspects, a display device that displays a hospital room in which a hospitalized patient is zero is attached on the flow line of the bed.

  According to the present invention configured as described above, a nurse call is made to request the support of another medical worker at the timing when the bed moves from a hospital room where another patient is present to a patient room where there is no other patient. Requesting the support of other medical staff as soon as possible when moving a patient from bed to room that is vacant in addition to a patient whose condition is changing suddenly Can do.

  Further, according to another aspect of the present invention, since the patient radio signal is read from the patient radio transmitter attached to the patient, only the bed is moved to a vacant room. Misinformation can be prevented.

  According to another aspect of the present invention, when a patient whose condition is suddenly changed is moved to an empty room, the empty room is displayed on the display device. The patient can be moved quickly.

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 a nurse call main | base station. It is a block diagram which shows the modification of the nurse call system by this embodiment.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a configuration example of a nurse call system according to the present embodiment. In the nurse call system according to the present embodiment, the description of the configuration and operation when the patient calls the medical staff is omitted. In FIG. 1, reference numeral 1 denotes a nurse call parent device, which is installed in a nurse station where medical personnel are resident. 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 an interface 5.

  A wireless transmitter 10 is attached to a bed (not shown) in a hospital room. Here, the wireless transmitter 10 is supplied with power and transmits a wireless signal when it approaches a reading range of the wireless reading device 20 described later. The radio signal includes bed identification information (for example, a bed number) for identifying the bed to which the wireless transmitter 10 is attached from other beds.

  Reference numeral 20 denotes a wireless reader, which is attached in the vicinity of the entrance / exit of each hospital room, and reads a wireless signal transmitted from the wireless transmitter 10 approaching the reading range. Here, the wireless reading device 20 is connected to the nurse call parent device 1. Moreover, it is preferable that the radio | wireless reader 20 reads a radio signal from the radio transmitter 10 which passed the entrance / exit of the hospital room. In addition, the wireless reading device 20 that has read the wireless signal adds hospital room identification information for specifying the hospital room in which the wireless reading device 20 is installed, and outputs the information to the nurse call parent device 1.

  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 alerting | reporting part 3 is comprised by the speaker, the display display, etc., and alert | reports the call which requests | requires the support of another medical worker from a medical worker by an audio | voice or a display. Here, since the nurse call cordless handset (not shown) is connected to the nurse call system by this embodiment, the alerting | reporting part 3 is used also when alert | reporting the call from a patient. Therefore, 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 call from a medical worker. The notification content of the notification unit 3 includes room identification information indicating the room where the call is being made.

  For each room, the storage unit 4 stores room information indicating the capacity of the room and the number of patients currently admitted to the room in association with the room identification information (see FIG. 2). 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 interface 5 is used for communication by connecting the nurse call master 1 and the wireless reading device 20 installed in each hospital room. In the example shown in FIG. 1, the interface 5 connects a wireless reading device 20 installed in a first hospital room and a wireless reading device 20 installed in a second hospital room. The interface 5 inputs a wireless signal to which the room identification information is added from the wireless reading device 20.

  Next, the operation of the nurse call system configured as described above will be described. The medical staff visits the patient's room by calling or patrol with a nurse call cordless handset (not shown). At that time, if the patient's condition changes suddenly, the healthcare worker will move the patient out of the room, bedside, unless the room is a private room or there are no other hospitalized patients. Move. When the bed passes through the entrance of the hospital room, power is supplied to the wireless transmitter 10 attached to the bed, and the wireless transmitter 10 transmits a wireless signal.

  The wireless reading device 20 that has read the wireless signal adds the room identification information to the wireless signal and outputs it to the nurse call parent device 1. When the interface 5 of the nurse call master unit 1 inputs a radio signal, the control unit 2 extracts the bed identification information and the room identification information included in the radio signal and refers to the storage unit 4 to extract the extracted room. Based on the room information stored in association with the identification information, it is determined whether or not the number of patients in the room and the number of patients hospitalized in the room are two or more. Corresponds to one control).

  Then, when the number of hospital rooms and the number of hospitalized patients are both 2 or more, a wireless signal including the same bed identification information as the extracted bed identification information is input from the wireless reader 20 installed in another hospital room. It is determined whether or not (corresponding to the second control in the claims).

  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 in which a patient in a hospital room is moved from bed to bed for reasons other than a sudden change in condition, or a case in which only a bed in a 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 out of the room by bed brings the patient into a private room or a room without inpatients. When the bed passes through the entrance of the hospital room, power is supplied to the wireless transmitter 10 attached to the bed, and the wireless transmitter 10 transmits a wireless signal. Since the bed identification information included in this wireless signal is the same as the bed identification information included in the wireless signal input to the interface 5 earlier, a wireless signal including the same bed identification information as the extracted bed identification information is transferred to another signal. The control unit 2 determines that the input has been made from the wireless reader 20 installed in the hospital room. Then, the control unit 2 refers to the storage unit 4 and examines the room information stored in association with the room identification information included in the wireless signal input from the wireless reading device 20 installed in the other room. It is determined whether or not the number of patients admitted to the hospital room is zero (corresponding to the third control in the claims).

  Here, if the bed identification information does not match, the wireless signal including the bed identification information is transmitted from the wireless transmitter 10 attached to another bed, so that determination and control are performed separately. .

  When the control unit 2 determines that the number of patients admitted to the hospital room is not 0, there are other patients in the hospital room. Therefore, this bed movement is considered to be a simple bed movement (for transferring the patient to another hospital room) which is not related to a sudden change in the patient's condition.

  On the other hand, when the control unit 2 determines that the number of patients admitted to the hospital room is 0, there are no other patients in the hospital room. Then, the control part 2 operates the alerting | reporting part 3, and the alerting | reporting part alert | reports that the medical worker is requesting the support of another medical worker with hospital room identification information. Other medical workers who have grasped this notification will go to the hospital room of the destination and provide support.

  FIG. 2 is a diagram illustrating an example of the contents stored in the storage unit 4. For example, when a bed is carried out from a patient room with the patient room identification information “101”, when the bed is brought into a patient room with the patient room identification information “105” or a patient room with the patient room identification information “107”, the nurse call master unit 1 Notification is performed. Similarly, when a bed is carried out from the room of the patient room identification information “102” and “103”, when the bed is carried into the patient room of the patient room identification information “105” or the patient room identification information “107”, The notification is performed by the nurse call master unit 1.

  In addition, when a bed is carried out from the patient room of the patient room identification information “104”, there is only one inpatient in the patient room. Therefore, the nurse call master unit 1 is notified even if the bed is carried into any bed. Not done. Similarly, when a bed is carried out from the room of the room identification information “106”, there is only one patient in the room and there is only one inpatient in the room, so the bed was brought into which bed. However, the nurse call master unit 1 does not notify.

  In addition, when a bed is carried out from the hospital room of the patient room identification information “105” and “107”, since there is no patient in the hospital room, no matter which bed the nurse call master unit 1 is brought into Then no notification is made.

  As described in detail above, according to the present embodiment, the room information indicating the number of hospital rooms and the number of patients admitted to the hospital room is stored in the storage unit 4 of the nurse call parent device 1 for each hospital room. In addition, the wireless transmitter 10 is attached to the bed, and the wireless reading device 20 that reads a wireless signal when the wireless transmitter 10 passes through the entrance / exit of the hospital room is attached near the entrance / exit. Then, after the wireless reader 20 reads the wireless signal at the entrance and exit of a hospital room where the number of hospital rooms is equal to or more than two, the patient who is admitted to the hospital receives the wireless signal from the same wireless transmitter 10. When the wireless reading device 20 of the hospital room in which the patient is zero reads, the notification unit 3 of the nurse call parent device 1 notifies the request of the support of another medical worker in the hospital room. .

  As a result, the nurse call master unit 1 notifies the request of the support of other medical workers at the timing when the bed moves from the hospital room where other patients will be to the patient room where there are no other patients. When a patient is moved from bed to room to a vacant room in addition to a patient whose condition has suddenly changed, support from other medical staff can be requested as soon as possible.

  In the above-described embodiment, when the bed is moved from a multi-bed room where there are other inpatients to a room where there are no in-patients, the notification unit 3 of the nurse call master unit 1 performs notification. However, it is not limited to this. For example, when the bed is moved regardless of the sudden change of the container, a stop button for temporarily stopping the operation of the wireless transmitter 10 may be provided in the wireless transmitter 10. Thereby, if the cancel button is operated when the bed is moved from the multi-bed room to the hospital room where there are no inpatients, erroneous notification of the notification unit 3 can be prevented.

  In the embodiment described above, when an empty bed is moved from a multi-bed room where there are other inpatients to a room where there are no in-patients, the notification unit 3 of the nurse call master unit 1 notifies the user. I have gone there, but is not limited to this. For example, as shown in FIG. 3, when the patient wireless transmitter 11 is attached to the patient, the wireless signal is read from the wireless transmitter 10 attached to the bed, and the patient wireless signal is read from the patient wireless transmitter 11. Only the wireless reader 21 may output a wireless signal to the nurse call master unit 1.

  Specifically, as shown in FIG. 3, the patient wireless transmitter 11 is attached (or carried) to the patient, and a timer 22 for measuring time is provided in the wireless reader 21 to identify the patient from other patients. The wireless reader 21 is provided with a wireless reader storage unit 23 that stores the patient identification information for identifying the bed used by the patient specified by the patient identification information in association with each other. ing. Here, the patient radio signal transmitted from the patient radio transmitter 11 includes patient identification information.

  When the wireless reader 21 reads a wireless signal from the wireless transmitter 10, the wireless reader 21 operates the timer 22, and refers to the wireless reader storage unit 23, and the time measured by the timer 22 is a predetermined time ( For example, it is determined whether or not the patient wireless signal including the patient identification information stored in association with the bed identification information included in the wireless signal has been read by the time it is about 5 seconds). Determine whether or not there is. In addition, when the wireless reader 21 reads a patient wireless signal from the patient wireless transmitter 11, the wireless reader 21 operates the timer 22 and refers to the wireless reader storage unit 23, so that the timer 22 It is determined whether or not the radio signal including the bed identification information stored in association with the patient identification information included in the patient radio signal has been read until the measured time reaches a predetermined time (for example, about 5 seconds). To determine if there is a patient on the bed. Here, when it is determined that there is a patient on the bed, the wireless reading device 21 outputs a wireless signal including hospital room identification information to the nurse call parent device 1.

  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, as shown in FIG. 3, a display device 30 may be attached on the flow line of the bed, and hospital room identification information of a hospital room in which the number of hospitalized patients is zero may be displayed on the display device. . Here, the flow line of the bed may be a corridor or an entrance / exit of a hospital room. Moreover, the display device 30 is attached to the bed.

  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.
