Description

[Detailed Description of the Invention] Anesthesiologists are responsible for managing the body of a patient under anesthesia and recording it, but it is necessary to understand the biological information at any given moment in a macroscopic manner. The use of devices that provide detailed and large amounts of information is not suitable unless there is a particularly abnormal situation.

Therefore, in conventional anesthesia records, various information such as blood pressure and pulse rate is read sequentially by an anesthesiologist and written by hand on recording paper to judge the overall trend and provide it for future reference. The situation is such that they are so busy with their work that they do not have time to record the measured values and record them later or even take measurements.

This situation can lead to discrepancies, misreading and writing of data, and in the worst case scenario, the completeness of patient management may be compromised. .

In order to improve the current situation as described above, the emergence of a system that automatically takes in biological information at controlled timing and writes necessary data on a predetermined recording paper has been awaited.

In the present invention, an anesthesia progress recording device is constituted by a microcomputer, a memory and an input/output register controlled by the computer, and a biological measuring device and a plotter connected to the input/output register. We are trying to achieve this by processing biological data with a microcombicoater and providing a plotter with the ability to draw numbers or graphs every moment on anesthesia progress recording paper.

Next, the present invention will be described in detail with reference to the drawings. 1st
The figure is a configuration diagram of an anesthesia recording device according to the present invention. 10
Reference numeral 1 denotes a microcombination circuit, and its peripheral circuits include a control signal line group 102, an address line group 103, and a data line group 1.
04 to the excavator 1050 at a timely and appropriate electrical control signal.
Input/output based on the time of occurrence.

A selection signal issued by a decoder 106 that allocates a function to each peripheral element by combination of address line groups 10 and 10 is sent through a selection signal line group 107 to a read memory in which a program is stored, that is, ROM1Q8, and to a read memory that stores a program, that is, an omitted read memory, that is, It, A M 109 and a turnout register so-called boat 110 are energized. The boat 110 can also be called an external information input/output window for the microcontroller system described above. .

The board 1-110 includes a plotter 120 that actually performs anesthesia recording, an AD converter 121 that converts analog signals into digital signals, a digital input terminal 126 that inputs digitized signals, and predetermined data. In particular, there is a fixed data input device 124 for manually inputting letters, numbers, etc. such as doctor's name, drug name, etc., and a manual numerical formula that is designed to arbitrarily express numerical values corresponding to the data recorded by the fixed data input device 124. mosquito device 125,
Switch 126 for recording the doctor's will if necessary
, a lamp 127 that indicates a device malfunction, input failure, etc., and an alarm 128 that serves to notify when the plotter 120 begins to move are connected. Reference numeral 129 indicates a time opening for recording at regular intervals. 140 is a recording medium, such as a magnetic tape or a disk, which non-volatilely stores data as needed.

130 is a body temperature sensor, 161 is a respiratory waveform detector, 1 and 62 are anesthetic gas concentration side, and 166 is a gas flow meter, all of which are A.
I) Connected to converter 121. 164 is a digital blood pressure terminal, which is connected to the digital input terminal 12;

The selection of a series of biomeasuring instruments such as this, il, etc. is only an example in this embodiment, and various other biomeasuring instruments may be applied as necessary.

Next, the operation of the anesthesia progress recording apparatus of the present invention will be explained based on the program flowchart 1 in FIG. 2(A). In the "initial top node", the initial state of the boat 110 is determined and the data in ItAM is made constant as necessary. "
In "Fixed data reading and writing", data inputted from a fixed data input device such as a magnetic card or a semiconductor memory, such as doctor's name, drug name, etc., is written on a predetermined recording paper using the plotter 120. The following example of the program flowchart is an example in which measurement and recording are performed every 5 minutes, or every 300 seconds, if no instructions are given. After recording the fixed data, the program waits for a while to check the clock 129 and repeats scanning of the manual input device 125 and switch 126.
-0 When 270 seconds have not elapsed since the previous recording, if the manual input device 125 or the switch 126 other than the 1 temporary key is operated, the block 120 indicates that if a predetermined mark such as "anesthesia" is pressed at a predetermined position on the recording paper, anesthesia will start. Mark the end.

The keys are used to record matters that cannot be known from electrical signals or to record the administration of a drug with a number corresponding to the drug number written from fixed data.

The "temporary" key is used specially when you want to record data at times other than fixed time intervals, and when you operate it, the digital blood pressure monitor 16
After starting 4, a series of body temperature side 160, respiratory wave detector 1
61, data from the anesthetic gas concentration meter 162, gas flow meter 166, and digital blood pressure meter 164 are read and recorded.

If more than 270 seconds have passed since the last recording, the program will start the digital blood pressure monitor 134 and then record 300 seconds.
Wait for the second. The time of 300 seconds during this time is plotter 1.
20 is the time it takes to start the operation, finish writing, and return to the starting point.If such a system of double waiting time is not used and the keys are always enabled manually, the switch 126 will be operated at, for example, 299 seconds. The 300th second cannot be recognized in the program, and the time delay will be accumulated later.
Or you may have to wait indefinitely.

However, the time of 30 seconds should of course be changed depending on the speed of the plotter used.

When the 300th second comes, various data are read and each data is entered. Also, the recording medium 140 operates as required.

While the above mentioned program is running, as shown in Figure 2 (
A special training routine such as B) is operated periodically by a flag sensing method or an interrupt method. That is, the clock is advanced by 1 second every second, and the plotter 1200 time axis, for example,
Advance the axis by 1 second.

The reason why the program runs every 0.5 seconds in Figure 2 (B) is only possible due to the convenience of the overall system.Whether it is i seconds or 0.25 seconds, it is fine as long as 1 second can be subtracted. .

Also, the time axis is calculated every second, but it is okay to calculate it all at once when the plotter moves.

Also, although I did not mention each step in detail, the plotter arm is programmed to move away from the recording paper, for example, to the left after the block finishes drawing a number or graph. This is due to the fact that it is arranged so that it is easy to see the progress on the recording paper, and that it should normally be possible to write by hand.

By configuring this anesthesia recording device with the equipment organization and program described above, even when anesthesiologists are busy, situations such as failure to record, misreading, or writing errors can be avoided, leading to even more accurate patient management. It will be.
