Description

The present invention relates to a nurse call system used in a hospital or a care facility.

As is well known, a nurse call system is mainly installed at a hospital or a nursing facility for a patient to talk to a nurse (such as a caregiver at a nursing facility). In this nurse call system, each bed is provided with a hand-type slave unit having a hand push button or a call function used by a patient for calling and a call button. There is a wall-mounted cordless handset on the side wall of the head of the bed. It is connected to a hand-push button or hand-type cordless handset, and when the patient presses the call button, it is installed from the wall-mounted cordless handset near the entrance of each room. The nurse call master unit installed in the nurse station (a staff station in a nursing facility) is notified via a corridor light. In the nurse call master unit, the room number / bed number where the call is made is displayed, a ringing tone sounds to inform the nurse, and the nurse can pick up the handset to talk to the patient.
(For example, see Patent Document 1)
Japanese Patent No. 2887552 Patent Publication 2002-191648

For infusions for infusions or medications to patients, the nurse has traditionally placed several tens of minutes or regularly visited the hospital room to confirm the completion, or a timer that the nurse has (for example, a kitchen timer) To check the room when the timer is up, or to receive a nurse call from the patient and know the end of the drip from the call.

It is a waste of nursing work that nurses go to hospital rooms many times to confirm the end of infusion, which hinders the original nursing work. In addition, since a nurse must take care of a plurality of patients, when setting a timer, a plurality of timers must be prepared. The notification of the end of infusion by the nurse call from the patient places an extra burden on the patient and is not always grasped at an appropriate timing, and in some cases, a delay occurs in the subsequent treatment, which is very undesirable.

Thus, for example, a system that attaches a sensor for measuring weight or a sensor for detecting the position of the liquid surface to the infusion device, connects the detection signal to the nurse call slave unit, and notifies the nurse call master unit of the end of the infusion. ing. (For example, see Patent Document 2)
However, such a system has a drawback that the infusion apparatus becomes complicated and expensive.

The present invention has been made in view of the above points, and provides a system that can always notify the end of infusion at an appropriate timing without using a complicated and expensive apparatus.

In order to achieve the above object, the present invention displays a timer unit that can measure the infusion time on the corridor lamp, a setting panel unit that can set the infusion time, etc., and the patient name and the remaining drip time for each patient A display panel unit that can be used, and a control processing unit that detects that the set infusion time has expired and generates a notification sound, and communicates the end of the infusion to the nurse call master.

The infusion time is set by selecting either the time required for infusion after selecting a patient, the infusion end time, or the amount of infusion and the flow rate per unit time. When the setting is completed, timing starts, and the remaining drip time can be displayed and confirmed at any time by the operation of the nurse. In addition, an infusion indicator can be provided to start blinking when timing is started, and when the remaining drip time decreases, the infusion situation can be notified by increasing the blinking cycle stepwise.

The setting panel unit and the display panel unit can be combined with a touch panel system that can be set by touching the screen. The infusion time can be counted simultaneously by counting softly with a combination of a timer unit and a control processing unit composed of a microcomputer.

When the nurse call master receives a drip end message from the corridor lamp, the nurse call master displays the corresponding room number, bed number (or patient name) and drip end and informs the nurse with a ringing sound.
It is also possible to provide a voice synthesizing function in the corridor lamp, and when the nurse lifts the handset of the nurse call master unit, the end of the infusion can be notified by voice.

Since the present invention is based on monitoring the infusion time with a corridor lamp, and since a plurality of timers can be set, a nurse has conventionally had a timer (such as a kitchen timer) for each patient individually. It becomes unnecessary.
If you do not have a timer, the nurse will have to go to the room several times to confirm the end of the infusion, but this is not necessary by monitoring the infusion time with a corridor light.
In addition, the drip time can be set with the corridor lamp, and the infusion progress can be roughly grasped in the corridor from the blinking speed of the drip indicator lamp, and the remaining drip time can be viewed by operating with the corridor lamp. , Nurses do not have to return to the nurse center and the flow line is shortened.

By monitoring the infusion time with a corridor lamp, a complicated and expensive infusion device with a sensor is unnecessary, and the patient does not have to bother with the need to notify the end of the infusion.
The corridor lamps are basically equipped with a display / setting function and a microcomputer. Therefore, infusion time monitoring is costly as equipment by adding a timer unit, voice synthesis function, and infusion time monitoring software. Can easily be achieved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows the structure of the corridor lamp. FIG. 2 shows a basic configuration example of a nurse call system.
FIG. 3 shows an operation flow relating to drip time management of the corridor lamp.
FIG. 4 shows an example of a display panel that displays the infusion time of the corridor lamp.
FIG. 5 shows an example of a setting panel for setting the drip time of the corridor lamp.

In FIG. 2, the nurse call master unit (1) and the corridor lamp (2) are connected by a communication line (8). On the bedside of the hospital room, there is a hand-push button (4) for calling a nurse call or a hand-type handset (5) equipped with a call button and a call function. And connected to the corridor lamp (2). When the patient presses the call button, the call is notified to the nurse call master (1) via the wall mounted slave (3), the corridor lamp (2) and the communication line (8), and the nurse call master (1). Then, the corresponding room number / bed number (or patient name) that has been called is displayed and a ringing tone is sounded to notify the nurse. When the nurse picks up the handset, he can talk to the patient.

In FIG. 1, a control processing unit (12) is a part for controlling the operation of the corridor lamp (2), and includes a microcomputer memory and its peripheral circuits. The control processing unit (12) communicates with the nurse call master (1) via the communication control unit (9). The wall mounted slave unit (3) is connected via a slave unit connection part (21). Also, a setting panel section (14), a display panel section (15), a patient-specific infusion display lamp (16), a patient-specific call display lamp (17), a call representative display lamp (18), a recovery button (6), a speaker (20 ) Are connected via the input / output unit (13).
A timer unit (10), a speech synthesizer (11), and a patient-specific infusion display lamp (16) are provided to perform infusion time management with the hallway lamp (2).

In order to set the infusion time, the setting panel unit (14) is used, and the set time and the patient name are stored in the control processing unit (12). When the setting of the infusion time is confirmed, the infusion timer prepared for each patient starts timing with the reference clock obtained from the timer unit (10).

When checking the progress of the infusion timer (drip remaining time), the contents can be viewed on the display panel (15) by operating the setting panel (14).
Simultaneously with the start of time measurement of the infusion timer, the patient-specific infusion display lamp (17) blinks, and by increasing the blinking speed as the infusion remaining time decreases, the remaining infusion time can be roughly known.

The control processing unit (12) constantly monitors the infusion timer and, when the infusion time expires, communicates and informs the nurse call master unit (1) of the room number, bed number, and infusion end information. In addition, the patient-specific infusion display lamp (17) is changed from blinking to continuous lighting, and a sound is emitted from the speaker (20) to notify the nurse passing through the hallway.

When there is a call response from the nurse call parent device (1), the control processing unit (12) plays a voice message of drip end held in the voice synthesis unit (11). When the nurse who knows the end of the infusion with the corridor light presses the recovery button (6) after confirmation, the patient-specific infusion display light (17) is turned off and the ringing sound is stopped.

In FIG. 3, when an operation is performed on the setting panel section of the corridor lamp (step 3a), it is necessary to input a personal identification number. (Step 3b) Since a general person such as a visitor passes through a corridor of a hospital or a nursing care facility, it is necessary to protect the operation based on a personal identification number. In FIG. 5, the password input button (30) is pressed and the password is input using the numeric keypad (37). (Step 3b)
Only when the personal identification number is correctly input (step 3c), various settings can be made. (Step 3d)

When setting the infusion time, the infusion time setting button (31) is pressed, the patient is designated (33), and the time is input with the numeric keypad (37). (Step 3e) Since the set numerical value is displayed on the numerical value display (36), if there is an error in the setting, it can be started again by pressing the cancel button (35). When the setting confirmation button (34) is pressed (step 3f), the drip timer provided for each patient starts timing, and the drip indicator lamp starts blinking. (Step 3g)

In order to view the remaining drip time, the drip remaining display button (32) is pressed (step 3r), and the drip remaining time is displayed on the display panel as shown in FIG. Press the recovery button (Step 3s)
Turn off the remaining drip time. (Step 3t)

It is the operations of Step 3m and Step 3n that the blinking speed of the drip indicator lamp increases as the remaining time decreases after the drip time has elapsed.

When the infusion time of a patient expires (step 3h), information on the end of the infusion is communicated to the nurse call master unit, and the sound of the sound and the infusion display lamp are changed to continuous lighting in the hallway light. (Step 3i)
When there is a call response from the nurse call master (step 3p), a voice message indicating the end of infusion is sent from the corridor lamp to the nurse call master. (Step 3q) When a nurse is present at the corridor lamp and confirms the end of the drip and presses the recovery button (step 3j), the sound of the corridor lamp is stopped and the drip indicator lamp is turned off.
(Step 3k)

In FIG. 5, the drip time is set, but it is possible to set the drip end time instead of the drip time. It is also possible to set the drip amount and the flow rate per unit time.
When the time setting, the amount of infusion, and the flow rate are set, the calculation is performed by the control processing unit (12) and converted into the infusion time.
In FIG. 4, the drip display lamp is provided independently, but it may be provided as an image in the display panel.
Although the setting buttons and the numerical value display in FIG. 5 are provided independently, it is also possible to use a touch panel method in which an image is displayed on the display panel and can be operated by touching the image.

When setting infusion by time, it is not always necessary to have a clock circuit with a corridor lamp, and time management can also be performed by periodically receiving time information from the nurse call master unit. In addition, the infusion timer for each patient is not held by the corridor lamp, but is held by the nurse call master unit, and the setting and display of the infusion can be realized by sharing the functions of the corridor lamp.
There is no voice synthesis function for each corridor lamp, and it is possible to have it on the nurse call master unit side. Having each function in the nurse call master unit without providing each function in the corridor lamp is negative in terms of risk dispersion, but it is economically advantageous.
