The respective flow rates and electric conductivity of the infusion and the urine with time are sent to an upper system from an antenna 33 of a communication unit 32 through a serial interface 31 at every sampling period.

Description

Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to medical monitoring equipment, and more particularly to a system for monitoring infusion patients.

2. Description of the Related Art In a conventional infusion patient monitoring system, the minute flow rate of an infusion solution is monitored and an alarm is issued when the scheduled flow rate is reached. In addition, the urine flow rate of the patient is visually measured with a urine meter at regular intervals. In addition, the electrical conductivity of infusions and patient urine was monitored by regular sampling.

However, the above-mentioned prior art is not a monitoring system that responds to changes in the patient's condition over time. For example, it has not been possible to monitor the condition of the patient in real time, such as displaying the water balance and electric conductivity balance of the patient in time. An object of the present invention is to realize highly accurate medical treatment by monitoring the flow rate and electrical conductivity of infusion and urine in real time.

[Means for Solving the Problems] In the infusion patient monitoring system for monitoring the flow rate of an infusion solution, the above-described object is to display means such as a graph, and to measure the electrical conductivity of the infusion solution and the urine flow rate of the infusion patient in real time. It is achieved by providing a means for measuring the electric conductivity and displaying the water balance and the electric conductivity balance of an infusion patient over time.

By measuring the minute flow rate and the electrical conductivity of infusion and urine in real time, it is possible to display the time of water balance and conductivity balance of an infusion patient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.
This will be described with reference to FIGS. 3 and 4. FIG. 1 is a block diagram showing a part of the configuration of the present invention.
The infusion solution (1) is supplied to 4) via the drip cylinder (2) and the infusion pump (5). The infusion pump (5) has a structure in which the outer side of the infusion tube (22) is compressed and moved by a roller or a finger to deliver the infusion solution (1) to the patient and does not directly touch the infusion solution. In addition, the microcomputer system (3
0) receives the flow rate signal (4) from the flow rate measuring means (3) and outputs a setting signal (6) to the infusion pump (5) so as to obtain a preset flow rate. Also, for infusion, a waste liquid means is provided after measuring the required amount. That is, the infusion tube (22) is branched by the three-way stopcock (11) and then is thrown into the waste solution bottle (12) by the infusion monitor pump (8) via the check valve (7). The electric conductivity is measured by the electrode (10) while the infusion is being discharged, and the result is stored in the storage unit of the microcomputer system (30). Further, the microcomputer system (30) responds to the drive signal (9) to the monitor pump (8) according to the discard amount in order to monitor the amount of infusion (for example, 1/100 to 1/1000) corresponding to the infusion rate. Output the number of times. Alternatively, it is driven at any time by the time management program of the microcomputer system (30). That is, by providing the infusion monitor pump (8) or the infusion draining means, it is possible to safely measure the electrical conductivity of the infusion without applying a current directly to the infusion supplied to the patient. Then, the urine of the transfused patient is accumulated in the urine pack (21) through the bladder indwelling catheter (15) and the vinyl ureter (20). As shown in the figure, there are a flow velocity detecting means (16) and an electric conductivity measuring means (18) in the middle of the urinary tract, which are respectively output to the microcomputer system (30). In this way, the microcomputer system (30)
The minute flow rate and the electric conductivity of each of the infusion solution and urine stored in are sent to the host system from the antenna (33) of the communication unit (32) via the serial interface (31) at every sampling cycle (the drawing is omitted). ). The system is a 1: N telemetry system that manages multiple infusion patients. The personal computer or printer of the master station displays the time chart as a monitoring record graph as shown in FIGS. 2, 3, and 4 for each patient. FIG. 2 is a time display regarding the infusion solution supplied to the patient. In Figure 2, one of the patients
The minute infusion amount (41), the total infusion amount (42), the infusion conductivity (43), and the total infusion conductivity (44) in the day are respectively represented by time graphs. Further, in the memo field (40), the treatment record such as the drug administration time and the drug name can be written.
Similarly, FIG. 3 is a time display regarding the urine of an infusion patient. In Figure 3, the patient's daily minute urine volume (51), total urine volume (52), urine conductivity (53) and total urine conductivity (54).
Are each represented by a time graph. Fig. 4 shows a transfusion patient
It is a time graph showing the balance of water and electric conductivity in one day, and the water balance (61) and the water balance total amount (6
2), the conductivity balance (63) and the total conductivity balance (64) are displayed in time. The respective calculation formulas are shown below. Water balance = Volume of fluid per minute − Volume of urine per minute Water balance Total volume = Total volume of fluid − Total volume of urine Conductivity balance = Volume of fluid conductivity − Conductivity of urine Total conductivity balance = Volume of total fluid conductivity − Total urine conductivity The parameter is an important factor for determining an infusion agent, an infusion amount, an infusion rate, etc. for an infusion patient. As described above, instead of monitoring only the flow rate of infusion, in the patient monitoring system for infusion, the electrical conductivity of the infusion, the flow velocity and the electrical conductivity of urine are monitored in real time with a display means such as a graph. By providing such a means, it is possible to accurately display the water balance and the conductivity balance over time.

According to the present invention, not only medical treatment with high accuracy can be provided to infusion patients, but also the burden on medical staff such as nurses can be reduced.
