Description

DETAILED DESCRIPTION OF THE INVENTION Background of the Invention (1) Technical Field The present invention relates to an electronic sphygmomanometer equipped with a storage unit that stores measured blood pressure values at any time.

(2) Prior Art and its Problems Conventionally, this type of electronic blood pressure monitor has memorized all measurement data except for when the device determines that the measured data is clearly an abnormal value. However, in cases where this type of electronic blood pressure monitor is used at an individual level,
It is difficult to judge a blood pressure value measured by someone else as an abnormal value, and even though it is meaningless, it is memorized and may cause confusion when comparing blood pressure values to be measured in the future. There were many flaws.

Purpose of the Invention The present invention has been made in view of the above-mentioned prior art. By making it possible to erase the data displayed on the electronic blood pressure monitor, it is possible to easily erase abnormal values measured in the past and blood pressure information stored by a third party. This is what we are trying to provide.

Configuration of the Invention In order to solve this problem, the electronic blood pressure monitor of the present invention has the configuration shown below. That is, an electronic sphygmomanometer comprising a storage section that stores a plurality of minimum units of a set of blood pressure measurement data obtained as a result of blood pressure measurement, wherein a first one of the blood pressure measurement data stored in the storage section is provided. a search means for extracting the smallest unit of blood pressure measurement data from the latest data in response to a first signal inputted by the input means; and each time the smallest unit of blood pressure measurement data is extracted by the search means , a display means for updating the display with the contents of the blood pressure measurement data; and a display means for updating the display with the content of the blood pressure measurement data; and erasing means for erasing the minimum unit of blood pressure measurement data displayed immediately before the second input means is energized from the storage unit when the second signal is input by the second input means.

Further, it is preferable that the blood pressure measurement data search/deletion process is terminated when the first input means or the second input means is not activated for a predetermined period of time.

DETAILED DESCRIPTION AND OPERATIONS OF THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of the electronic blood pressure monitor of this embodiment.

In the figure, 1a is a CPU that controls each peripheral device and circuit in this block diagram, and 1b is a series of programs related to blood pressure measurement and a subroutine program of the flowchart diagram shown in FIG. 2 in the search/delete mode described later. ROM where etc. are stored
It is. Further, 2 is a storage unit that stores the measured blood pressure value, its pulse rate, etc., and 3 is a pressure transducer that outputs the pressure value in the cuff as an analog quantity. 4
converts the analog signal from the Korotkoff sound detection circuit 6, which detects the Korotkoff sound from the pulse sound from the pressure transducer and the sound collecting microphone 5, into a digital signal,
It is an A/D converter that outputs to CPU1a,
Through this A/D converter 4, the CPU 1a measures the blood pressure value and pulse rate based on signals from the Korotkoff sound detection circuit 6 and the pressure converter 3. Further, 7 is a display section that displays various measurement data, messages, and the like. 8 is a search switch that outputs a signal to the CPU 1a to search for various measurement data in the storage section 2; 9 is a search switch that outputs a signal to erase the data etc. searched by the search switch 8;
This is an erase switch that outputs to the CPU 1a.

FIG. 2 is a flowchart of the search and delete routine. For example, the signal generated by inputting the search switch 8 is used as an interrupt signal to the CPU 1.
Output to a.

In step S1, data such as the systolic blood pressure value, diastolic blood pressure value, and pulse rate of the most recent blood pressure measurement result are displayed on the display section 7.

Next, in step S2, it is determined whether the search switch 8 or the erase switch 9 has been input. If the search switch 8 is input at this time, the data immediately preceding the currently displayed measurement data is read from the storage unit 2 in step S3, displayed on the display unit 7, the timer is reset, and the process returns to step S2. return. If no input is made for a certain period of time, this process ends (step S5). Furthermore, when the erase switch 9 is input, the data currently displayed on the display section 7 is erased from the storage section 2, and the process ends.

As explained above, according to this embodiment, each time the search switch 8 is input, a set of diastolic blood pressure value, systolic blood pressure value, and pulse rate obtained in one measurement is searched from the present to the past. The direction will be displayed.
When data that the user clearly recognizes as abnormal values is displayed due to incorrect wearing of the wrist cuff related to blood pressure measurement and noise contamination, the user simply performs the first operation of inputting the erase switch 9 while the information is displayed. You can delete the information by simply doing this. Furthermore, it becomes possible to search and delete data that has been used by another person, thereby eliminating confusion.

Furthermore, when the search switch 8 is input, the reason why the latest measurement results are used as a reference and the results are displayed sequentially is to respond immediately if it is determined that the results measured this time are abnormal. ,and,
This is because the closer the measurement data is to the present, the greater its significance.

Further, in this embodiment, an interrupt signal is used for executing the subroutine of the search/erase mode, but the present invention is not limited to this, and the CPU 1a may use the interrupt signal for judgment at any time.

Effects of the Invention As explained above, according to the present invention, each time one key operation is performed, the data obtained in one measurement is sequentially displayed in the past, and the data is displayed with one key operation. Since the data is erased, it becomes possible to easily erase abnormal values measured in the past and blood pressure information that was used and stored by a third party.
