is the power switch.

Next, the operation of the above-mentioned centrally monitored drip device configured as described above will be explained based on a flowchart.

First, on the main body side of each infusion device, Fig. 5 (a) and (b)
As shown in the flowchart, when the power switch 22 is turned on, it is determined whether communication with the monitoring device is possible, and if possible, the communication indicator lamp 19 lights up. If it is determined that communication is impossible due to a poor connection of the connector 31 of the signal cable 30, etc., the buzzer 21 issues a communication failure alarm. In this case, the lamp 19 is not lit.

In the next step, the assembly type 'MWo of the drip container suspended from the hook arm 6 is measured.

Next, enter the total drip amount T from the numeric keypad 17.

When (total weight of liquid 9 in container 8) is input,
In the CPU 28, the incidental weight M of the container 8, tube 10, etc. is calculated. This additional weight M is M=W0−To.

Subsequently, the infusion is started on the patient, and the start switch 23 is pressed.
When is pressed, the start signal and the total infusion fiTo data are sent to the monitoring device.

Next, the weight W of the drip container suspended from the footer arm 6 is measured at regular intervals, and the CPU 28 subtracts the incidental weight M from this weight fiW, thereby reducing the amount of drip remaining during the drip to the patient. The amount T (the remaining amount T of the liquid 9 in the container 8) is calculated. The above-mentioned intravenous drip amount T is T
=WM.

Subsequently, it is determined whether there is a data sending command from the monitoring device, and if there is a command, data on the remaining amount of intravenous drip T is transmitted to the monitoring device, and the remaining amount of intravenous drip -1itT is displayed on the digital display section 1. If there is no data sending command after a predetermined waiting time, it is determined that there is a communication failure, the buzzer 21 issues a communication failure alarm, and the communication indicator lamp 19 is turned off.

In the next step, it is determined whether the intravenous drip re-injection switch 26 has been pressed, and if it has been pressed, a re-immersion signal is sent to the monitoring device and the remaining amount T of the intravenous drip is measured again.

Next, it is determined whether there is an abnormality in the measurement data,
If there is an abnormality, an abnormality alarm will be issued from the buzzer 21,
An abnormal alarm signal is sent to the monitoring device. Here, if the tube 10 is broken and the liquid does not flow normally, or if the intravenous injection needle is pulled out and there is an abnormal outflow of the liquid, the drip container 8
If the hook arm 6 is cracked or an abnormal load is applied to the hook arm 6, an abnormality will occur in the measurement data of the remaining drip 1-1-.

After an abnormality occurs, the author decides whether to reset the measurement of the remaining amount of drip T and restart the drip, or to stop the drip.
If you want to reset, turn on the reset switch 25. This sends a reset signal to the monitoring device.

If the user wishes to stop the drip, the stop switch 24 is turned on. This operation moves to the end operation, and the buzzer 2I issues an infusion end alarm.

Further, if the measured data is normal, it is determined in the next step whether or not the cancel switch 24 has been pressed, and if it has been pressed, the process proceeds to the end operation in 8 lines.

Subsequently, the CPU 28 determines whether the remaining amount of intravenous drip iT is approximately zero or not, and if it is not zero, the remaining amount of intravenous drip T is measured again. After the infusion to the patient has finished,
When the data is determined to be approximately zero, an infusion end alarm is generated and an infusion end signal is sent to the monitoring device.

Subsequently, it is determined whether a termination permission signal has been received from the monitoring device, and if so, the termination permission indicator lamp 20 is lit.

Based on the lighting of this lamp 20, the operator can turn off the power switch 22.

The above is the flow of the operation procedure of each drip device main body.

Next, the operation of the monitoring device will be explained based on the flowchart of FIG.

First, patient data stored in advance on a floppy disk or the like is input manually from the memory device 42 . Here, the patient data includes the patient's name, hospital room number and bed number, time and type of drip given to the patient, amount of drip, etc.

Subsequently, when a start signal indicating that the infusion has started is received, the computer 37 displays on the CRT 4 the hospital room and bed number where the infusion has started based on the start signal.
0, and the patient's name is searched and displayed on the CRT 40.

Subsequently, when the data of the total drip amount T0 is received, the CRT
The drip amount ff1To is displayed in the column of the corresponding patient in 40.

Next, a data sending command is sent to the corresponding operating infusion device, and if the data is received, the received infusion amount i is
Display T on the CRT 40. If the data is not received even after a predetermined waiting time, the buzzer 39 issues a communication failure alarm, and the CRT 40 displays that a communication failure has occurred in the corresponding drip device body.

When the intravenous drip re-injection signal is received after the remaining amount T of the intravenous drip is displayed, the CRT 40 displays that the intravenous fluid has been re-injected into the corresponding drip device main body.

Subsequently, when the abnormal alarm signal is received 3, the buzzer 3
In step 9, an abnormality alarm is generated, and the fact that an abnormality has occurred in the main body of the infusion device is displayed on the CRT 40. In response to this alarm, a nurse or the like who has been waiting at a nurse's station or the like can rush to the hospital room of the patient who is receiving an intravenous drip where an abnormality has occurred.

In the next step, it is determined whether or not a reset signal has been received, and if it has been received, the display of the corresponding remaining drip amount T in the CRT 40 is cleared and the operation procedure returns to the state of waiting for reception of a start signal.

If the reset signal is not received, it is determined whether or not an infusion end signal has been received, and if it is received, an infusion end alarm is issued at the buzzer 39, and the completion of the infusion for the corresponding patient is displayed on the CRT 40. This end alarm may cause a nurse or the like to rush to the patient's room.

After the completion of the infusion is displayed on the CRT 40, various data are stored in a floppy disk or the like in the memory device 42, and a termination permission signal is sent to the corresponding infusion treatment body, and the operation procedure returns to the state of waiting for reception of a start signal.

If the infusion end signal is not received, the data is stored in the memory device 42, a data sending command is sent again, the data is received, and the infusion amount fiT is finally displayed on the CRT 40.

The processing of the above operations is carried out in parallel for the plurality of infusion device main bodies by communicating with the plurality of infusion device main bodies in chronological order.

The various data stored on the floppy disk in the memory device 42 are processed in another device and tables, graphs, etc. are created to obtain clinical data such as the progress of infusion for each patient. Can be done.

In this way, with the above-mentioned centrally monitored infusion device, it is possible to centrally monitor the progress of multiple infusions and the completion of multiple infusions at the nurse's station, etc., making it possible to safely administer infusions to patients. .

Additionally, since an alarm is issued in the event of a communication failure or abnormality, it is possible to take immediate action and prevent accidents from occurring.

Note that the infusion device main body may be provided with a function that can temporarily hold the measurement of the remaining amount of infusion T. This hold function is effective when restarting the infusion after temporarily interrupting the infusion to the patient.

Furthermore, in measuring the remaining drip iT, instead of using the load sensor 14, a displacement sensor may be used to detect the displacement of the hook arm 6 suspended by a coil spring. Further, photosensors may be arranged in tandem on the outside of the drip container 8 to detect the level of the liquid 9 in the container 8 and measure the remaining amount T of the drip.

In addition, communication between the infusion device main body and the monitoring device is not limited to the wired method using the communication cable 33, and a wireless method may also be used (Effects of the Invention) As explained above, in the present invention, The infusion device itself is configured to automatically detect the end of the infusion and send an infusion end signal to, for example, a monitoring device in the nurse's station. There is no need to visually confirm the completion of one infusion and use a buzzer switch to notify the end of the infusion, which eliminates the inconvenience of the conventional method.

Furthermore, according to the present invention, even if a patient falls asleep during an intravenous drip, or if the patient is in a critical condition, a nurse or the like waiting at the nurse's station can confirm that the infusion has ended, and the patient can be immediately informed. You can rush to the hospital. Therefore, it is possible to prevent problems such as backflow of blood into the drip tube due to leaving it alone after the drip is completed, and it is possible to safely drip drip into the patient.
