[0012]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings as appropriate.
[0013]
(1) First Embodiment (1-1) Configuration of First Embodiment FIG. 1 is a block diagram showing a home sphygmomanometer according to a first embodiment of the present invention. Here, the sphygmomanometer 1 has a cuff 2 configured to be held around the patient's wrist, and a main unit 3 is arranged on the outer peripheral side of the cuff 2. The sphygmomanometer 1 is configured such that the cuff 2 is wrapped around the wrist of the patient and is always carried by the patient.
[0014]
Here, in the main unit 3, the power supply 4 supplies power to each part of the sphygmomanometer 1 from a power supply of a dry battery or an AC adapter. The pump 5 operates under the control of the control unit 6 to inject air into the cuff 2 and press the wrist of the patient around which the cuff 2 is wound. The exhaust valve 7 is operated under the control of the control unit 6, and gradually discharges the air injected into the cuff 2, thereby reducing the pressure of the cuff 2 pressing the wrist of the patient. The pressure sensor 8 detects the pressure due to the air injected into the cuff 2 and outputs a pressure detection signal S1 to the control unit 6. Thereby, in the sphygmomanometer 1, the pressure received by the cuff 2 from the wrist of the patient is detected by the pressure sensor 8, and the pulse of the patient can be measured by the control unit 6 by the pressure detection signal S 1 from the pressure sensor 8. Further, the control unit 6 can measure the systolic blood pressure and the diastolic blood pressure by changing the wrist pressing force by the cuff 2.
[0015]
The liquid crystal display unit 10 displays various measurement results and messages by the main unit 3 under the control of the control unit 6. The alarm 11 generates a warning sound at a predetermined time under the control of the control unit 6. The timer 12 is started under the control of the control unit 6 and notifies the control unit 6 of time information. The interface (I / F) 13 is, for example, an input / output circuit such as a USB (Universal Serial Bus). In the sphygmomanometer 1, the sphygmomanometer 1 is connected to, for example, a computer in a hospital via the interface 13, and can upload measurement results. In addition, the time until the blood pressure is measured after the medication is set can be set.
[0016]
The memory 14 records and retains a processing program in the control unit 6, a blood pressure measurement result, and a time from the time of medication input via the interface 13 to the time of measuring blood pressure (hereinafter, referred to as measurement time). The event switch 15 is a switch for activating the timer 12, and is configured to notify the pressing operation by the patient to the control unit 6. In the sphygmomanometer 1, the doctor instructs the patient to operate the event switch 15 when taking the medicine. The start switch 16 is an operator for instructing measurement of blood pressure by the sphygmomanometer 1, and is configured to notify the control unit 6 of a pressing operation by a patient.
[0017]
The control unit 6 is a computer that controls the operation of the sphygmomanometer 1, and includes an analog-to-digital conversion circuit that inputs the pressure detection signal S1 by performing an analog-to-digital conversion process, a driving circuit that drives the liquid crystal display unit 10, and the like. Has been done. The control unit 6 executes a processing program stored in the memory 14 in response to the operation of the event switch 15 and the start switch 16, thereby executing a predetermined processing procedure and controlling the operation of each unit. .
[0018]
FIG. 2 is a flowchart illustrating a processing procedure of the control unit 6 triggered by the operation of the event switch 15. In this processing procedure, the control unit 6 proceeds from step SP1 to step SP2, detects the operation of the event switch 15, and starts the timer 12 in the subsequent step SP3. Thus, the control unit 6 measures the elapsed time after the patient takes the medicine with the timer 12.
[0019]
Subsequently, the control unit 6 proceeds to step SP4, determines whether or not the time measurement result by the timer 12 is the measurement time recorded in the memory 14, and if a negative result is obtained here, repeats step SP4. On the other hand, when the time measurement result by the timer 12 becomes the measurement time recorded in the memory 14, the process proceeds from step SP4 to step SP5 to drive the alarm 11 and display a predetermined message on the liquid crystal display unit 10. Here, this message is a message that prompts measurement of blood pressure. Thus, after taking the medicine, the control unit 6 instructs the patient to measure the blood pressure when the measurement time recorded in the memory 14 elapses.
[0020]
When the alarm is driven and the message is displayed in this manner, the control unit 6 proceeds to step SP6 and determines whether or not the output of the alarm has been completed for all the measurement times recorded in the memory 14. If a negative result is obtained in step SP4, the process returns to step SP4 and waits for the subsequent measurement time to drive the alarm 11. On the other hand, if a positive result is obtained in step SP6, the process proceeds from step SP6 to step SP7, and this processing procedure ends.
[0021]
Thus, when a plurality of measurement times are recorded in the memory 14 in units of, for example, 30 minutes, the control unit 6 prompts the patient to measure the blood pressure every 30 minutes after taking the medicine. .
[0022]
On the other hand, FIG. 3 is a flowchart showing a processing procedure when the start switch 16 is operated by the patient by prompting the patient to measure the blood pressure in this manner. In this case, the control unit 6 proceeds from step SP11 to step SP12, and detects the operation of the start switch 16. Subsequently, the control unit 6 proceeds to step SP13, drives the pump 5 and the like to measure the blood pressure and the pulse, and displays the measurement result on the liquid crystal display unit 10. In the subsequent step SP14, the elapsed time is obtained from the timer 12, and the elapsed time and the measurement result are recorded in the memory 14.
[0023]
Thereby, the control unit 6 records and stores the elapsed time after taking the medicine and the blood pressure measurement result in the memory 14. The control unit 6 subsequently proceeds to step SP15, determines whether or not the blood pressure measurement has been completed for all of the measurement times recorded in the memory 14, and if a negative result is obtained here, proceeds to step SP16. This processing procedure ends. On the other hand, if a positive result is obtained in step SP15, the process proceeds to step SP17, in which the operation of the timer 12 is stopped, and then proceeds to step SP16 to end the processing procedure.
[0024]
Thus, in the sphygmomanometer 1, the event switch 15 constitutes a detecting means for detecting the taking of the medicine, and the timer 12 measures the lapse of time after taking the medicine based on the detection result by the detecting means. A timer is configured. The cuff 2, the pump 5, the exhaust valve 7, the pressure sensor 8, and the control unit 6 constitute a blood pressure measuring means for measuring blood pressure, and the memory 14 stores a blood pressure value measured by the blood pressure measuring means and an elapsed time by a timer. And a memory for recording the information.
[0025]
(1-2) Operation of the First Embodiment In the configuration described above, the sphygmomanometer 1 is connected to a hospital computer via the interface 13 when a patient goes to a hospital and receives a prescription for a medicine. After taking is measured in the memory 14 until the blood pressure is measured.
[0026]
Thereafter, the sphygmomanometer 1 is held on the patient's wrist, and the patient operates the event switch 15 when taking the medicine. Thus, the sphygmomanometer 1 measures the elapsed time after taking the medicine by the timer 12, and when the elapsed time reaches the measurement time set in the hospital, the alarm 11 outputs a warning sound and the liquid crystal display section. At 10, a message prompting measurement of blood pressure is displayed. This allows the patient to be encouraged to measure the blood pressure after taking the medicine, if he forgets to measure the blood pressure, or even if he intentionally avoids the blood pressure measurement. Regarding the continued medication, the effect of the medication can be surely confirmed even in patients at home medical treatment.
[0027]
Thus, when the timing of the blood pressure measurement is notified in this manner, the patient operates the start switch 16 in a seated, resting state, for example. In 1, air is pumped into the cuff 2 by the pump 5, and the systolic blood pressure is measured by the control unit 6 by the pressure detection signal S 1 output from the pressure sensor 8. After that, the air in the cuff 2 is caused to flow out by the exhaust valve 7, and the control unit 6 measures the diastolic blood pressure by the pressure detection signal S1. At the same time, the pulse is measured.
[0028]
In the sphygmomanometer 1, the measurement results obtained in this way are displayed on the liquid crystal display unit 10, and are recorded and stored in the memory 14 together with the elapsed time after taking the medicine. Further, the next time the patient goes to the hospital, the record in the memory 14 is uploaded to the computer of the hospital via the interface 13, whereby the measurement result and the elapsed time are displayed on this computer, for example, to confirm the efficacy.
[0029]
In this series of processing, the measurement result is recorded in the memory 14 with the lapse of time after taking the medicine, for example, by measuring the blood pressure at a time different from the time at which the original blood pressure should be measured, Measurement results measured before the effect of the drug has not appeared, as well as measurement results measured in a state where the effect of the drug has weakened after a sufficient time can be reliably determined, so that patients at home remedies etc. Even if there is, the effect of the medication can be surely confirmed.
[0030]
(1-3) Effects of the First Embodiment According to the above-described configuration, the elapsed time after taking the medicine is recorded together with the blood pressure measurement result, so that even if the patient is at home medical treatment, the patient can be surely recorded. The effect of medication can be confirmed.
[0031]
Also, by outputting a warning to measure blood pressure based on the elapsed time after taking the medicine, if blood pressure measurement is forgotten, or if blood pressure measurement is intentionally avoided, blood pressure measurement is encouraged. Therefore, the effect of the medication can be surely confirmed, for example, with respect to the medication that has been continued for a certain period of time, even in patients at home.
[0032]
(2) Second Embodiment In this embodiment, the current time is constantly measured by the timer 12, and the time when the event switch 15 is operated, the measurement time elapses, and the blood pressure measurement by the start switch 16 according to the current time. Detect the time of Further, the time at which the event switch 15 is operated and the time of blood pressure measurement are recorded in the memory 14, so that the elapsed time of blood pressure measurement is recorded in the memory 14 after taking the medicine. In addition, by effectively using the mechanism for monitoring the current time by the timer 12, the user is notified of the timing of taking the medicine by driving the alarm 11 and displaying a message on the liquid crystal display unit 10.
[0033]
In this embodiment, the configuration is the same as that of the sphygmomanometer 1 of the first embodiment except that the processing of the time information related to the timer is different.
[0034]
According to this embodiment, the time when the event switch 15 is operated and the time of blood pressure measurement are recorded in the memory 14 according to the current time by the timer, so that after taking the medicine, the elapsed time of the blood pressure measurement is stored in the memory 14. The same effect as in the first embodiment can be obtained by recording.
[0035]
In addition, by effectively utilizing the mechanism for monitoring the current time by the timer 12 and notifying the user of the timing of taking the medicine, it is possible to keep the medicine from being forgotten. With respect to the administered medication, the effect of the medication can be surely confirmed even in patients at home and the like.
