Abstract

PURPOSE:To enable the measuring of a correct blood pressure both on a wrist and on an upper arm with one unit of a sphygmomanometer which has hemostatic bands different for the wrist and for the upper arm according to mounting locations of the hemostatic bands. CONSTITUTION:This apparatus is provided with a hemostatic band 1 for an upper arm and a hemostatic band 2 for a wrist, connection plugs 6 and 7 to be combined exclusively for these hemostatic bands and a plurality of fine speed exhaust valves whose numbers opened are selected according to the exclusive connection plugs 6 and 7 on a piping path within the body of a sphygmomanometer. Thus, hemostatic bands 1 and 2 for the upper arm and the wrist and the plugs 6 and 7 exclusively for these hemostatic bands are used according to purposes and an exhaustion is performed corresponding to the hemostatic bands. This structure enables accurate measurement of a blood pressure both on the upper arm and on the wrist with one unit.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic sphygmomanometer that monitors a change in pressure in an arm band using a sensor to measure a blood pressure value.

[0002]

2. Description of the Related Art Generally, in blood pressure measurement, when blood pressure is measured in the upper arm of a subject as shown in FIG. 4, an upper arm tourniquet 1 and an air rubber tube 5 for feeding pressurized air into the upper arm tourniquet 1 When the blood pressure is measured by the unit composed of the blood pressure monitor main body 3 for the upper arm and the blood pressure is measured on the wrist of the person to be measured, the tourniquet 2 for the wrist, the air rubber tube 5, and the blood pressure monitor main body for the wrist measurement. The blood pressure was measured by the unit composed of 4.

[0003]

By the way, a general electronic sphygmomanometer is a dedicated tourniquet suitable for being attached to a blood pressure measurement site and a dedicated tourniquet for lowering the pressure in the tourniquet at an appropriate speed. It consists of a main body with a built-in slow exhaust valve. Therefore, when the measured blood pressure value measured at a certain place seems to be wrong, even if it is attempted to measure and confirm it at another place, the tourniquet and the sphygmomanometer dedicated to that place must be purchased again. Further, even if only the tourniquet is changed according to the measurement point, the air volume in the tourniquet is different, the exhaust speed is not appropriate, and the processing system in the sphygmomanometer main body cannot be applied as it is.

In view of the above-mentioned conventional problems, the present invention provides an electronic sphygmomanometer that can share the sphygmomanometer main body even if only the tourniquet is changed according to the measurement point, and can correctly measure blood pressure at an appropriate exhaust speed. It is an object.

[0005]

In order to solve such a problem, the present invention is provided with tourniquets for the upper arm and wrist, and is provided with a plug for main body dedicated to each tourniquet and the main body is provided with a plug. A plurality of fine speed exhaust valves are provided, and the number of opened fine speed exhaust valves differs depending on the dedicated connection plug.

[0006]

In the above structure, when the tourniquet for the upper arm is used, the number of the slow-moving exhaust valves is increased by connecting the dedicated connection plug to reduce the exhaust volume, and when the tourniquet for the wrist is used, the connection plug for the dedicated connection is connected. Thus, the number of fine speed exhaust valves to be opened is reduced to reduce the exhaust amount, that is, the exhaust speed is adjusted, and accurate blood pressure measurement can be performed using any tourniquet.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the electronic sphygmomanometer of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of this embodiment.
The same components as those in the conventional example are designated by the same reference numerals. As shown in the figure, the electronic sphygmomanometer is provided with an upper arm tourniquet 1 and a wrist tourniquet 2, and a tip of each air rubber tube 5 is an upper arm tourniquet dedicated connection plug 6 and a wrist tourniquet dedicated connection plug 7. Is attached. The sphygmomanometer main body 18 is provided with an air pipe path connection port 10 through which the connection plug 6 for exclusive use of the tourniquet for the upper arm and the connection plaque 7 for exclusive use of the tourniquet for the wrist can be freely connected.
Further, in the sphygmomanometer main body 18, an air pipe passage 10a connected to the air pipe passage connection port 10, a fine speed exhaust valve A8, a fine speed exhaust valve B9, a pressure sensor 11, a pump 12, a quick exhaust valve 13 are provided.
Is provided, and further receives a signal from the pressure sensor 11 to control the pump 12 and the quick exhaust valve 13, and a display device 15 for receiving a signal from the control device 14 and displaying a blood pressure value.
A power switch 16 for inputting to the control device 14 and a pressure switch are provided.

FIG. 2 shows the upper arm tourniquet cord-dedicated plug 6 and the wrist tourniquet cord-dedicated plug 7, each of which has an O-ring on the outer circumference of the large-diameter portion for shutting off the outside air and the pipe passage connection port 10 in the sphygmomanometer body. A19 is provided, and only the wrist tourniquet plug 7 is provided with an O-ring B20 for shutting off one of the slow speed exhaust valves on the outer circumference of the connection portion 7a having a small diameter.

FIG. 3 is a schematic diagram when the upper arm tourniquet plug 6 and the wrist tourniquet plug 7 shown in FIG. 2 are connected to the air pipe connection port 10 of the sphygmomanometer main body 18. Generally, the capacity of the tourniquet 2 for the wrist and the tourniquet 1 for the upper arm are larger in the tourniquet 1 for the upper arm, and therefore the displacement of the tourniquet 1 for the upper arm is increased in order to make the exhaust rates the same. There is a need.

Therefore, in this embodiment, when the wrist tourniquet plug 7 for wrist is connected to the air pipe connection port 10 of the sphygmomanometer body 18, as shown in FIG. 3B, the ventilation to the slow exhaust valve A8 is an O-ring. At B20, the air in the wrist tourniquet 2 is exhausted only from the slow exhaust valve B9. Conversely, the upper arm tourniquet plug 6 is connected to the air pipe connection port 10 of the sphygmomanometer main body 18.
When connected to the O-ring B2 as shown in Figure 3 (a)
Since there is no 0, the exhaust from the upper arm tourniquet 1 is exhausted from both the slow exhaust valve A8 and the slow exhaust valve B9, and the exhaust amount increases.

As described above, by properly using the dedicated plugs for the upper arm tourniquet and the wrist tourniquet, respectively, it is possible to measure the correct blood pressure at the correct pumping speed for both the upper arm and the wrist.

[0012]

As is clear from the description of the above embodiment,
According to the present invention, the tourniquet for each of the upper arm and the wrist and the plug for the tourniquet are selectively used, and by changing the number of the slow exhaust valves in the sphygmomanometer main body at the time of exhaust, one wrist can be worn by one sphygmomanometer. However, accurate blood pressure measurement can be performed. Further, when the measured blood pressure value measured at a certain place is significantly different from the normal value, the blood pressure value can be confirmed again by changing only the tourniquet.

Further, since parts other than the tourniquet and the dedicated connection plug, that is, each constituent part of the sphygmomanometer main body can be shared by the upper arm type and the wrist type, mass production of the parts is possible, which is convenient for cost reduction. .
