Description

[Detailed description of the invention] The present invention relates to a blood pressure measurement method.

Various blood pressure monitors are available that measure blood pressure using a microcombiator (hereinafter referred to as a microcomputer). [Figure 1 shows an example]. In the figure, 1" is a cuff band that is wrapped around a human arm, etc., and the inside of this cuff band is electret.

A sound collecting microphone 2 such as a microphone is built-in. 3 is a blood pressure needle body, and the blood pressure needle body 3 mainly includes a pressure sensor 4 that detects the pressure in the blood pressure zone and converts it into voltage, and a converter that converts the signal from this pressure sensor 4 into a digital signal. 5 and a microcomputer 7 which receives a signal from a filter circuit 6 which extracts a sound signal from the sound detected by the converter 5 and the microphone 2 into a pulse signal, and operates according to the given fa program. , and a display 8 made of a liquid crystal or the like to which signals from the microcomputer 7 are applied and display the blood pressure.

When measuring blood pressure, the sound is collected into the blood pressure needle body 3. A microphone 2 is attached, and blood pressure is measured via a nine cuff tube and a cord (not shown), and pulse rate is measured at the same time. That is, the cuff band l is wrapped around the arm and the pressure is detected by the pressure sensor 4, which converts the pressure into a voltage. The receiver converts it into digital data using the A/D converter 5 and sends it to the microcomputer 7. The microcomputer 7 that receives the pressure data converts the pressure data into pressure and displays the blood pressure on the display 8. Further, a microphone 2 attached to the cuff band 1 captures pulse sounds and sends them to a filter circuit 6. This filter circuit 6 uses a signal (
KII signal) and a Kolokotov sound signal (KL signal) for determining the diastolic blood pressure are extracted and transmitted to the microcomputer 7. On the other hand, upon receiving the information, the microcomputer 7 takes appropriate steps to prevent noise, determines the systolic blood pressure and the diastolic blood pressure, and displays them on the display 8. At the same time, we also measured the pulse rate.
The pulse rate is also displayed on the display 8.

However, with such a blood pressure needle, the rounding program for blood pressure measurement is uniformly determined by the microcomputer 7. For example, the blood pressure can be measured by a nurse who is familiar with measuring blood pressure, and also by an elderly person who is not accustomed to measuring blood pressure. However, it is not convenient to use a fixed two-chart that follows a single program, and it is not easy to use. It had drawbacks such as requiring a

The present invention has been proposed in view of the above points, and its purpose is to make it possible to select a program in a microcomputer depending on the person performing the measurement, and to increase the number of microcomputers. To provide a method for measuring blood pressure in a vehicle ahead of the vehicle, allowing various users to select the most suitable blood pressure measurement system without any trouble.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 shows an example of the self-pressure measuring method according to the present invention, and the ruler indicated by a in the figure is the essential part of the present invention.

First, the RAM of my computer in Atsushi 1 diagram.

If the systolic blood pressure has been determined at 10M*0 and the pressure band l is still being pressurized, the systolic blood pressure is cleared as shown in Figure 2 and the blood pressure is measured again. The program: After displaying an error on the display 8, the cuff l is evacuated, and it is determined whether the pressure of the cuff l has become, for example, 20ss+Hg or less, and if this is true, the blood pressure is again A program is prepared that starts the measurement, and if not, continues the evacuation operation, judges the pressure value in the same manner as described above, and then starts the blood pressure measurement again. Let's now temporarily use the former program as a measurement program for people who are skilled in blood pressure measurement, such as nursing nurses, and the latter program as a measurement program for unskilled people who are inexperienced in blood pressure measurement, such as the elderly. Then, to select such a program, for example, by operating a changeover switch, a signal of H level t&FiL level is obtained as a select signal such as MM, original, etc., and the desired program can be selected thereby. In this embodiment, the configuration is such that when the signal level is H level, the signal level for experts is selected, and when the signal level is L level, the fvs mode for unskilled users is selected.

When measuring blood pressure according to the present invention, first, the blood pressure needle main body 3 is powered on, and then, if the measuring person is an experienced person such as a nurse, the above-mentioned program for an expert is activated in advance by an H level signal. Select. Next, as shown in FIG. 2, the cuff band 1 is pressurized to start blood pressure measurement, and at the same time, the microphone 2 outputs a sound signal (K0):17 sound signal (K, signal).
Based on the detection, the microcomputer 7 determines the systolic blood pressure and displays it on the display 8). If the pressurization of the cuff band l has been stopped at the time of the test, it means that the self-pressure measurement has been carried out normally, and the diastolic blood pressure is then determined by the following: Display this and finish the measurement. In addition, determine whether re-measurement is necessary and take remeasurements as necessary.

After determining the systolic blood pressure, if the cuff band 1 is still pressurized, it is determined that an abnormal event has occurred, taking into account the effect on the human body, and abnormal handling is performed.In other words, the above-mentioned H level Since the program for experts (according to the signal of is executed. (Although not shown, it is necessary to perform an evacuation operation on the cuff band 1 at this time.) Therefore, an expert can perform abnormal processing such as when the light intensity hypertension value displayed on the display 8 disappears due to the clearing operation. All you have to do is know what happened and re-measure.

Furthermore, if the program for non-skilled personnel is selected by the L level signal caused by the switching operation, then in the case of the above-mentioned abnormality processing, the error display on the display 8 will first notify the user that the measurement has failed. , the unskilled person was made aware that #i measurement had failed, and the subsequent exhaust operation,
This can accurately indicate the transition to re-measurement.

As described above, according to the present invention, the blood pressure measurement program can be freely selected according to the proficiency level of the person being measured. of! This has the effect of realizing a blood pressure measurement method that is easy to use.
