Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a long-time blood pressure monitor using an oscillation method.

(b) Conventional technology In medical institutions, it is necessary to know patient data accurately and quickly. Regarding blood pressure, the relationship between antihypertensive drug administration and blood pressure is important data, and there is a strong desire to know the temporal changes in blood pressure after drug administration.

Therefore, conventionally, “Nihon Rinkyu Vol. 39 No. 7 (7゜1981
) As disclosed in J's "24-hour blood pressure measurement method and its significance", blood pressure can be measured over a 24-hour period by inserting a catheter into an artery and recording the measurement results with a data recorder. was being attempted.

B→ Problems to be solved by the invention In the prior art, invasive methods or bedside devices were used to measure blood pressure over long periods of time. It was not possible to measure the temporal changes in blood pressure.

In addition, some conventional technologies use data recorders to record measurement results, and analysis requires special playback equipment, making it difficult to obtain patient data quickly, and large and portable devices. It was inconvenient.

Furthermore, when using the device for home use, one must always keep an eye on the measurement time, and if one forgets to take a measurement, there is a problem that important data may be lost.

B) Means for Solving the Problems The present invention provides, in addition to the usual means necessary for blood pressure measurement such as a cuff and a sensor, a clock part, a notification part for telling the time of blood pressure measurement or the time of administration, and a measuring part. The apparatus is constructed by providing a memory for storing blood pressure values and measurement times for a long period of at least one day, and an interface for inputting the contents of the memory to a host computer for aggregation.

(E) Effect In the present invention, the alarm unit announces the time of blood pressure measurement or the time of administration, so it can be used even at home.

Measurements can be performed reliably without forgetting, and the measurement results are displayed on the display means. In addition, the measurement results and measurement times are stored in a conveniently portable memory, so when you visit a hospital, you can simply connect the interface to your host computer.
It becomes possible to quickly display a total of blood pressure trends, etc.

(F) Embodiment FIG. 1 is a block diagram schematically showing a long-term blood pressure monitor according to the present invention, and FIG. 2 is an external view thereof.

In the figure, (1) is a cuff wrapped around the patient's upper arm;
(2) is a mechanical part that pressurizes and depressurizes the cuff and applies external pressure to the upper arm; (3) and (4) are an oscillation sensor and a pressure sensor that detect oscillation and pressure caused by blood flow, respectively; 5) and (6) are preamplifiers that amplify each sensor output, and (7) is a preamplifier (5).
and (6) a processing unit that calculates systolic and diastolic blood pressure values and pulse rate based on the detection results input through (6), (8) a clock unit, and (9) a time at which blood pressure should be measured or a medication administration time. Q (l is the measured systolic and diastolic blood pressure values and pulse information as shown in Figure 2).

Furthermore, there is a display section that digitally displays the alarm setting time,
αD is R with non-volatile memory or backup function
A memory that stores the measured blood pressure value, pulse rate, and measurement time including month and day; (111 is an operation switch consisting of alarm setting switches (12a) (12b) and a reset switch (126);

αJ is the host computer α for tabulation installed in the hospital.
4) is an interface for inputting the contents of the memo IJtlυ, and a9 is a speaker for outputting an alarm sound.

Therefore, the patient first operates the alarm setting switches (12a) and (12b) while looking at the display section α■.
Set the blood pressure measurement time. In this case, the administration time of the antihypertensive agent may be set.

Then, at the set time, the alarm section (9) generates an alarm sound from the speaker (19) to notify the patient that it is time to measure blood pressure. Upon receiving this, the patient or an attendant turns on the mechanical section ( 2) to start blood pressure measurement.In other words, when the alarm sounds, wrap the cuff (1) around the upper arm, operate the reset switch (12c), and then
Mechanical part (2) 1 For example, pressure is applied by a manual pump.

The results measured in this manner are displayed on the display section aα and are stored in the memory αD together with the measurement time.

Therefore, if medication and measurement are performed every 4 hours, measurement data for 6 times a day will be stored in the memory αB.

If the capacity of memory αD is large enough, one week or one
The measurement data of the month is stored in the memory (111).

Then, once a week or once a month, you visit a hospital with this blood pressure monitor and connect the interface α3 to the hospital's host computer (+41). Ba,
As shown in Figure 3, the daily blood pressure trend Durham,
One month's blood pressure fluctuations can be quickly displayed or printed out.

Therefore, from these displays or printouts, physicians should
It is possible to know the relationship between medication and blood pressure values for the patient, which is useful for subsequent treatment.

In the above-described embodiment, the time setting of the alarm part is performed using the operation switch of the blood pressure monitor, but the time setting may be performed from the host computer α4 when visiting a hospital. Alternatively, a pump for automatic pressurization may be provided as the mechanical part (2), and pressure may be automatically applied inside the can by operating a switch.

(G) Effects of the Invention According to the present invention, it is possible to reliably and easily measure blood pressure in daily life, where one spends a long time, and it is also possible to quickly process the measurement results. In particular, the relationship between medication and blood pressure values, or
It becomes possible to provide important data for medical activities, such as diagnosis of pseudohypertension such as white coat hypertension.
