Description

DETAILED DESCRIPTION OF THE INVENTION (a) Technical Field of the Invention The present invention relates to medical measuring devices used for disease diagnosis, daily health management, etc., and in particular, to obtain required information by converting physical quantities into electrical quantities. Related to medical measuring devices.

(b) Prior Art and Problems Sphygmomanometers are not only used in medical offices for diagnosing diseases, but also widely used at home for daily health management. A sphygmomanometer pumps air into a cuff wrapped around the arm of the person being measured, presses the upper arm to temporarily stop the blood flow in the artery, and then gradually releases the air. The pressure at which blood begins to flow into the artery again is the systolic blood pressure, and the pressure at which the natural blood flow returns is the diastolic blood pressure, and these values can be read on a scale or in numbers. Detection is performed using an electronic blood pressure monitor, and an outline of the electronic blood pressure monitor will be explained below with reference to FIG. FIG. 1 is a block diagram illustrating the operation of the electronic blood pressure monitor. 1st
The pressure gauge in the figure includes a cuff 1 equipped with a microphone 5, a pressurizer 2 that pumps air into it, a leak valve 3 that gradually reduces the pressure by leaking the pumped air, and a physical quantity such as blood pressure. A pressure-to-electrical converter 4 is connected to convert the signal into an electrical signal.

In addition, the output of the pressure/electricity converter 4 is converted by an analog/digital converter 6 and supplied to the storage devices 7 and 8.
The output of the microphone 5 is supplied to the systolic and diastolic blood pressure detectors 9 and 10, respectively, and the outputs are used as write command signals for the storage devices 7 and 8, and the outputs of the storage devices 7 and 8 are displayed on the display devices 11 and 12, respectively. I am trying to display it. Therefore, air is pumped into the cuff 1 to create a sufficiently high pressure,
When the leak valve 3 is opened after the vascular sound by the microphone 5 is no longer detected, the pressure gradually decreases and reaches a predetermined value, the vascular sound by the microphone 5 is detected, and the systolic blood pressure detector 9 displays the pressure at that time. It is displayed on the display 11. When the pressure in the cuff 1 further decreases and reaches a predetermined value, the microphone 5 no longer detects blood vessel sounds, and the diastolic blood pressure detector 10 displays the pressure at that time on the display 12.

As described above, electronic blood pressure monitors are widely used because they can be easily measured by anyone, but there is usually only one type of cuff used at home. On the other hand, in medical offices such as hospitals,
Multiple types of wristbands are prepared and used depending on the person to be measured, such as one for adults and one for children. Sensors with different electrical characteristics and measurement ranges are attached to these multiple types of wristbands, but the conventional method has the disadvantage that it is not possible to know from the outside what kind of sensors are built in. Furthermore, when measuring blood pressure, there is a drawback that more air pressure than necessary is applied to the person being measured.

(C) Purpose of the Invention The present invention has been made to solve the above-mentioned drawbacks.
The purpose of this invention is to provide a medical measuring device that prevents operational errors during measurement.

(d) Structure of the invention The present invention includes a converter that converts a physical quantity into an electrical signal,
A medical device that obtains desired information from an electrical signal from a transducer, the transducer, a means for setting an identification code indicating the type or electrical characteristics of the transducer, and a transmission for guiding the identification code and the electrical signal to the outside. A medical measuring device comprising: a first device having means; and a second device having determining means for determining the identification code by the transmitting means. As described above, in a blood pressure monitor using a transducer, the present invention provides a means for setting an identification code related to the transducer on a wristband to which the transducer is attached, and a means (connector) for extracting the identification code to the outside together with the electrical signal. etc.) and a means for determining the identification code from the connector, so that blood pressure measurement can be performed under appropriate conditions for the person to be measured. It is.

(e) Examples of the invention The present invention will be explained below with reference to the drawings. FIG. 2 is a block diagram illustrating an embodiment of the present invention. The piezoelectric transducer 5' in FIG. 2 corresponds to the microphone 5 in FIG. 1, and is provided inside the cuff 1.

The piezoelectric transducers 5' have different shapes, structures, electrical characteristics, and measurement ranges depending on the type of object to be measured (that is, the person to be measured) (adult, child, etc.). Moreover, the connectors 21 and 22 are connectors for taking out signals from the wristband 1 to the outside, 21 is a male (plug), 22
is a female (jack). In this embodiment, two of the seven pin terminals are used for the piezoelectric transformer 5', and the remaining five are used for the piezoelectric transformer 5'.
The individual is used to transfer the type code. In Figure 2,
The voltage supply line V from the piezoelectric transducer 5' is connected to the terminal P7 of the connector 21, while the sense line S is connected to the terminal P6. Therefore, when connectors 21 and 22 are mated, voltage v1 from power supply terminal 23 is applied to terminal J7. P7, the voltage is applied to the piezoelectric transducer 5/ by the voltage supply line V. The detection signal from the sense line S passes through terminals ps and Js, is amplified by an amplifier 24, and then sent to an analog-to-digital converter 6.

In the present invention, five terminals p1 of the connector 21 (and 22)
(Jt) to ps (J5) are used to transfer the type code. Terminal P5 of the connector 21 is a grounding terminal.
When the connectors 2 and 22 are fitted together, the terminal J5 is grounded. Four lead wires Ll” on the connector 21 side
One end of L4 is connected to terminal P5, and voltage V2 is applied from power supply terminal 25 via resistor R to four terminals J1 to J4 on the connector 22 side. When the four lead wires L1 to L4 on the connector 21 side are not connected to the terminals PI-P4 as shown in the figure, that is, in the open state, the four terminals J1 to L4 on the connector 22 side are connected when the connectors 21 and 22 are mated. The potential of J4 is the same potential as voltage V2. On the other hand, if the four lead wires LJ-L4 on the connector 21 side are connected to the terminals P1 to P4 (fixed with terminals etc.), when the connectors 21 and 22 are mated, the connector 22 side The potentials of terminals J] to J4 are all ground potential.

Therefore, depending on whether or not the four lead wires L1 to L4 are connected to the corresponding terminals P1 to P4, the information (type code) of 16 combinations can be transmitted from the connectors 21 to 22.
can be communicated to. For example, when lead wires L1 to L4 are connected to terminals PI to P4, this corresponds to a code of "0000" and is determined to be for adults, and lead wires L1 to L4 are connected to terminals PI to P4.
When L4 is not connected, this corresponds to the [1111J code, and this is determined to be for children, and codes for other combinations are used to identify other species.

When the connectors 21 and 22 are fitted together, the potential of the terminals Jl to J4 (V2 volts or 0 volts) is input to the determination circuit 26. The determination circuit 26 determines 9 by determining the input.
Outputs 16 determination signals AO-A1.5.

These determination signals AO to A15 can be used to identify the type of piezoelectric transformer 5'.

The embodiment is an example in which the maximum value of the air pressure supplied to the cuff 1 is controlled. In FIG. 2, determination signals (AO to AJ5) from the determination circuit 26 are sent to the search section 27. The search unit 27 searches the table 4 according to the received determination signal and finds the maximum value of the air pressure to be supplied to the cuff 1. For example, in the case of the judgment signal AO (adult), the maximum value of the air pressure is 2501, and in the case of the judgment signal A]5 (child), the maximum value of the air pressure is 140. The highest value of air pressure found by the search section 27 is sent to the comparison section 29 . The comparison unit 29 compares the output signal of the analog-to-digital converter 6 with the search unit 2.
7, and when the value of the output signal of the analog-to-digital converter 6 matches or exceeds the maximum value of the air pressure determined by the search unit 27, the pressurizer 2 control to stop the operation. As a result, when measuring blood pressure using the child cuff 1, it is possible to prevent applying more air pressure than necessary to the child being measured, and it is possible to control the air pressure depending on the type of cuff. Become.

(f) Effects of the Invention As described in F-F, the present invention allows the type of sensor attached to the cuff of the blood pressure monitor or the type of detected information to be identified from the outside, so that the processing of the detected information is easy. This method has the advantage of not only making it easier to tolerate, but also preventing misuse of the wristband, and allowing measurements to be performed under optimal conditions depending on the person being measured.
