Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial Application Field The present invention relates to a blood pressure needle having a slow exhaust mechanism and a rapid exhaust mechanism.

The slow exhaust mechanism and rapid exhaust mechanism in this type of blood pressure monitor according to the prior art are disclosed in, for example, Japanese Utility Model Publication No. 57-1924 and Japanese Utility Model Publication No. 55-12.
A device provided in a pressurized rubber bulb portion is known as disclosed in Japanese Patent No. 802.

However, in these conventional examples, switching between the slow exhaust mechanism and the rapid exhaust mechanism must be performed manually using the pressurized rubber bulb, which is cumbersome to handle.

□ (C) Purpose of the Invention The present invention automatically switches between the slow exhaust mechanism and the rapid exhaust mechanism in conjunction with the on/off switching of the electrical circuit, thereby simplifying handling, and When the switch is off, no air remains in the cuff to prevent errors when measuring blood pressure.

B) Structure of the Invention The blood pressure monitor of the present invention switches between a slow exhaust mechanism and a rapid exhaust mechanism within the blood pressure monitor body by an exhaust button that is operated in conjunction with a switch that turns on and off the power of the blood pressure monitor circuit. Pressurized air is exhausted, and the exhaust button is configured to be pressed by a switch knob to switch the slow exhaust mechanism to the rapid exhaust mechanism when the switch is moved to the OFF position. It is something that exists.

(E) Example (1) is a blood pressure monitor body with an integrated arm cuff, and a pressure rubber bulb (2
) is sent to the cuff bag in the arm cuff (4) through the air pipe (3) to compress the area around the subject's upper arm, and further into the cuff (4). The equipped Korotkoff sound detection microphone detects the Korotkoff sound, and the pressurized air is gradually exhausted by the slow exhaust mechanism (described later) provided inside the blood pressure monitor body (1), and the pressurized air pressure is further detected by the pressure sensor (5). is detected, and the air pressure when the Korotkoff sounds start to be produced is displayed as the systolic blood pressure, and the air pressure when the Korotkoff sounds disappear is displayed as the diastolic blood pressure on the display (6).

(7) is a printed circuit board housed within the main body (1);
On the surface of this printed circuit board (7) are the display device (6) and the microcomputer IC (8) that constitutes the blood pressure monitor circuit.
) and a sliding power switch (9) that turns on and off these blood pressure monitor circuits.

QOi is a slide switch knob that is slidably provided on the surface of the blood pressure monitor body (1), and this knob aO) is located in a recess on the back side (111 is inserted into the operation lever (9a) of the power switch (9)). The switch (9) is turned on and off as the switch knob slides when pushed in, and the blood pressure monitor body (1) is located on the back of the knob head.
An articulation protrusion Q3 is provided on the upper case (1B) and engages with the six articulation engagement parts to dynamically position the switch knob to the on and off positions of the switch (9). In addition, by forming an inclined surface (14B) at the lower end of the base of this articulating protrusion 03), the base becomes a pressing rib circle.

(2) is an exhaust valve device installed below the switch knob α0 on the back side of this printed circuit board (7).
) is a lower valve case that has a slow exhaust pipe aE bored in the center of the bottom surface, and an inlet pipe α9) on the side. The upper valve case has a cylinder (support) on the side, and these are integrated through a sealing ring seal. Further, (to) is a cylindrical packing that is fitted into the slow exhaust pipe 08 through the gap maintaining wire and covers behind the slow exhaust hole Qη. Furthermore, (E) is a quick exhaust button equipped with a suppressing part (26&) that can freely protrude from the quick exhaust hole (21),
This button (a) has a partition flange (26b) whose periphery is covered with a sealing cover gasket (2), and is constantly biased upward by a spring (28) to keep the cover gasket (26b) on the upper side. The upper part of the suppressing part (26B) is pressed against the inner surface of the upper bottom surface of the valve case (2), and the upper part of the suppressing part (26B) is formed into an inclined circumferential surface (29) whose diameter becomes smaller as it goes upward. This exhaust valve device (2) protrudes onto the printed circuit board (7) from the button insertion hole of the printed circuit board (7), and when the switch knob (10i) is in the OFF position, the switch knob (10i) is pressed. A rib (141) is equipped to press the top part of the suppression part (2<Sa) of the quick exhaust button (26).Furthermore, the pressure sensor (5) is connected to the outlet tube (support), and the pressure sensor (5) is connected to the outlet tube (support), Air pipe (3
) is connected to the inlet tube (19) via the air supply rubber tube (31) that communicates with the cuff bag, and therefore, this exhaust valve device is not pressed when the switch knob α0 is in the on position. Since the lip valve is not pressing the rapid exhaust button (a), the partition hook (26b) seals the inner surface of the upper bottom surface of the upper valve case (20j), and therefore, in this state, pressurized air flows through the gap maintaining wire (2). Through the gap between the cylindrical packing (end) and the slow exhaust pipe side formed by the slow exhaust hole a'
) constitutes a slow exhaust mechanism that slowly exhausts air through the
In addition, this pressurized air pressure is detected by the pressure sensor (5), and on the other hand, when the switch knob (10) is in the OFF position, the inclined surface (14B) of the pressurized lip is pressed against the rapid exhaust button ( By riding over the inclined peripheral surface of a) and pressing the top surface of the suppressing part (26a) of the button □□□), the partition flange pieces (26, b) resist the force of the spring. and lower the upper valve case @J and the flange piece (26b).
Therefore, in this state, pressurized air is rapidly exhausted from the rapid exhaust hole (21) through the exhaust passage, forming a rapid exhaust mechanism. The switch knob 00), which is slid to perform the on/off operation of the switch (9), presses the quick exhaust button (2)) in the off position to press the exhaust valve device 00).
5) is switched from the slow exhaust mechanism to the rapid exhaust mechanism, and when the power switch (9) is in the OFF position, the air pressure inside the cuff bag is completely zero to prevent measurement errors during subsequent blood pressure measurements. There is.

Shokuni is −j& wo pond,! 3) is a quick exhaust valve knob conventionally equipped on the pressurizing rubber bulb (2), and rapid exhaust can be performed even if this knob (33) is pressed manually.

(f) Effects of the Invention Therefore, according to the present invention, the slow exhaust mechanism of the exhaust valve device can be automatically switched to the rapid exhaust mechanism by simply turning the switch knob of the power switch to the OFF position, making it extremely easy to handle. Additionally, since the air pressure inside the cuff bag can be reduced to zero in the off position, no measurement error occurs during blood pressure measurement, making it possible to obtain a blood pressure monitor that can accurately measure blood pressure.
