Abstract

PURPOSE:To make an electronic blood pressure gauge easy to use for a very old person and set the optimum pressurization value for a user by displaying the pressurization value set by a pressurization value setting means at least at two positions of a display unit when no pressurization value is set by the pressurization value setting means. CONSTITUTION:The pressurization value set by a pressurization value setting means 4 is displayed at two positions of a display unit 6. The pressurization value is dedicatedly displayed at one position, and a user can confirm the pressurization value whenever necessary. The pressurization value is also displayed at the portion where blood pressure is displayed. The pressurization value is held by a pressurization value memory means 5, this value is automatically displayed on the display unit 6 when it is used again, and it is used as the pressurization value as it is if no change is required. If a change is required, it can be changed to the desired value within the range 50-280mmHg by a pressurization value setting means 4.

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for setting a pressurization value of an electronic blood pressure monitor and a display of the set value.

0002

2. Description of the Related Art In electronic blood pressure monitors, particularly automatic electronic blood pressure monitors, it is necessary to pressurize the armband to a value that is approximately 20 mmHg to 40 mmHg higher than the blood pressure of the user being measured. Since this pressurization value needs to be set each time depending on individual differences, physiological conditions, etc., conventionally, mechanical means such as a slide switch have been used.

0003

[Problems to be Solved by the Invention] Since slide switches have sliding contacts, they tend to malfunction due to mechanical friction, and their production costs are high. Further, setting the pressure value using the slide switch becomes particularly difficult as the person gets older, since the characters printed on the slide portion generally have to be smaller due to space constraints. Further, the values that can be set are discrete values at most three or four points, and the user cannot select the optimal value, so unnecessary pressurization is often forced.

The purpose of the present invention is to solve the above-mentioned problems, to achieve high operational reliability, low production cost, easy to use even for elderly people, and to be able to set the optimal pressure value for the user. The purpose of the present invention is to provide a pressurization setting means that can be used.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the present invention has the following configuration. That is, a cuff that compresses a part of the body, a pressurizing/depressurizing means that increases or decreases the pressure within the cuff, a blood pressure determining means that determines blood pressure from changes in the cuff pressure, and a blood pressure determining means that determines blood pressure from changes in the cuff pressure. In an electronic blood pressure monitor having a display means for displaying, the pressurization value setting means sets the pressurization value of the cuff, and the pressurization value storage means stores the pressurization value set by the pressurization value setting means. and the pressurization value set by this pressurization value setting means, if the pressurization value is not set by the pressurization value setting means, the pressurization value stored in the pressurization value storage means. are displayed on at least two locations on the display.

[0006]Furthermore, one of the at least two locations on the display that displays the pressurization value is a portion dedicated to displaying the pressurization value, and the other one is determined by the blood pressure determining means. This is the part that displays blood pressure.

Furthermore, the pressurization value set by the pressurization value setting means is set to an arbitrary value within the range of 50 mmHg to 280 mmHg.

[0008]

[Operation] According to the above configuration, the pressurization value can be set as follows. That is, the pressurization value set by the pressurization value setting means is displayed at two locations on the display. Since one of these places exclusively displays the pressurization value, the user can check the pressurization value whenever necessary. or,
This pressurization value is also displayed in the area that displays blood pressure and other information. In addition, this pressurization value is stored in the pressurization value storage means, and in the case of reuse, this value is automatically displayed on the display, and if the user does not need to change it, this value can be used as is. Used as a pressure value. If you need to make changes,
From 50mmHg to 280mmH depending on the pressure value setting means
g can be changed to any desired value within the range.
