Description

[0001] The present invention relates to a phantom and blood pressure monitor calibration system for blood pressure monitor calibration, and a blood pressure monitor calibration method using the same.

The present invention relates to a phantom and blood pressure monitor test system for blood pressure monitor test and a blood pressure monitor test method using the same. More particularly, the present invention relates to a pressure test apparatus and a control unit for forming a pressure, Phantom and blood pressure monitor calibrating system for blood pressure monitor test system which provides blood pressure monitor calibration phantom with blood pressure monitor calibration phantom and sphygmomanometer calibration and calibration server, And to a blood pressure monitor assay method using the same.

Human beings in modern society are struggling with the risk of heart and cerebrovascular diseases such as hypertension, diabetes, hyperlipidemia and heart disease, the metabolic syndrome. As a disease group called so-called adult disease, the incidence of adult diseases is increasing in Korea with the advancement of the diet.

The metabolic syndrome itself is not a serious disease in itself, but it is characterized by the fact that it does not have the symptoms of "a silent murderer", and that it can cause considerable complications and is not easy to cure.

Since such adult diseases usually cause changes in blood pressure, the continuous measurement of blood pressure has recently become more important as a representative means for predicting and diagnosing adult diseases.

Non-invasive blood pressure monitors among blood pressure monitors for measuring blood pressure can be classified into a mercury blood pressure monitor and an electronic blood pressure monitor.

The mercury sphygmomanometer is a method commonly used by specialists. It inserts the body part of the upper arm into the cuff, presses it with a pressure higher than the blood pressure of the human body, slowly lowers the pressure of the cuff while sensing the Cortecov tone with a stethoscope, And an electronic blood pressure gauge, that is, an oscillometric blood pressure meter, is a method of measuring blood pressure by sensing pressure oscillation with a pressure sensor.

Such an oscillometric blood pressure monitor can be easily used at home, and can be configured to measure blood pressure from the upper arm, the wrist or the finger, and has an advantage that the blood pressure value is expressed in digital form. However, it is a sensitive point that the accuracy is low. Therefore, caution is required because measurement of erroneous blood pressure can cause a serious judgment error of the user's current body condition.

In order to overcome the disadvantages of such an oscillometric blood pressure monitor, there has been a comparison with a mercury sphygmomanometer from time to time. However, it has been pointed out that it is difficult to handle the mercury sphygmomanometer since it is not an expert, and that the calibration device is inconvenient to carry due to a large number of accessory devices, and is expensive and difficult to use in the field easily.

Also, although the calibration should be performed after checking the blood pressure monitor, the operator may forget the calibration or the blood pressure of the patient may be measured by the uncorrected blood pressure monitor, thereby causing a medical accident.

Therefore, it is urgently required to develop a phantom and blood pressure monitor calibrating system for blood pressure monitor test, which is light and portable and has a high adaptability to the field.

FIG. 1 is a perspective view of a phantom for a blood pressure monitor test according to the present invention, and FIG. 2 is a perspective view of a phantom mounted on a blood pressure monitor for a blood pressure monitor test according to the present invention.

Will be described with reference to Figs. 1 and 2. Fig.

The phantom 10 for the blood pressure monitor test according to the present invention includes a body 100, a control unit 110, a power supply unit 120, a pressure forming unit 130, a pressure setting unit 140, and a data input unit 150 .

The phantom 10 for the blood pressure monitor test according to the present invention is easy to carry and light because the accessory devices are integrally formed in the phantom 10 unlike the prior art.

The body 100 is formed so as to have a resiliency similar to that of the blood pressure measuring part in order to reproduce the same situation as when the blood pressure monitor 20 measures the human blood pressure.

The body 100 elastically expands as pressure builds therein, and transfers pressure to the cuff 30 of the blood pressure monitor 20. [

The body 100 is provided with a power supply unit 120 for supplying power to the phantom 10. The power supply unit 120 may be a battery or a rechargeable battery.

The formation of the power supply 120 in the phantom 10 allows the phantom 10 to be portable and increases accessibility for blood pressure monitor verification.

The pressure forming portion 130 is disposed inside the phantom 10 to form a pressure inside the body 100. The pressure forming portion 130 may be an air pump or a hydraulic pump. Means for implementing the pressure forming part 130 may be selected by a person skilled in the art in consideration of various aspects such as weight, economy, and vibration.

The pressure setting unit 140 sets a pressure value to be formed by the pressure forming unit 130. [ The pressure setting unit 140 is preferably disposed on the front or rear surface of the body 100 to avoid interference with the cuff 30 when the phantom 10 is mounted on the blood pressure monitor 20. [

A standard blood pressure button 143, a low blood pressure button 146, and a high blood pressure button 149 are formed in the pressure setting unit 140. This is because the blood pressure monitor 20 measures the blood pressure of the patient in various pressure ranges, so that pressure formation in various pressure ranges is possible.

The phantom 10 is provided with a data input unit 150. The operator measures the pressure of the blood pressure monitor 20 while inserting the phantom 10 into the cuff 30 of the blood pressure monitor 20 in order to check whether the blood pressure monitor 20 normally operates. Then, the operator inputs the blood pressure measurement data measured by the blood pressure monitor 20 into the data input unit 150. [ That is, the data input unit 150 serves as an interface for inputting blood pressure measurement data measured by the blood pressure monitor 20.

This is because the blood pressure monitor 20 and the phantom 10 operate independently of each other and do not transmit and receive data between each other. However, when the blood pressure monitor 20 is manufactured to transmit measured blood pressure data between the blood pressure monitor 20 and the phantom 10, the user may omit the data input unit 150 for inputting the blood pressure measurement data to the phantom 10.

The blood pressure data measured between the sphygmomanometer 20 and the phantom 10 may be transmitted using a wireless transmission scheme such as Bluetooth or may be connected to a wired data cable to transmit and receive data.

The control unit 110 disposed inside the phantom 10 compares the pressure measurement value of the blood pressure monitor 20 input to the data input unit 150 with the pressure setting value set in the pressure setting unit 140, ) Is calculated.

For example, when the operator presses the low blood pressure button 146 in the pressure setting unit 140, a predetermined low pressure is formed inside the body 100 by the pressure forming unit 130, , The control unit 110 compares the measured low pressure with the pressure measurement value to calculate the measurement error.

Since the blood pressure monitor 20 measures people in various pressure ranges, it is necessary to test various pressure ranges to accurately determine whether the blood pressure monitor 20 is operating normally.

Therefore, the operator presses the standard blood pressure button 143, the low blood pressure button 146, and the high blood pressure button 149 to measure the pressure for different pressure ranges, and inputs the respective results to the data input unit 150.

Then, the control unit 110 calculates an average error obtained by averaging the measurement errors in the standard blood pressure, hypotension, and hypertension, and determines whether the average error exceeds a preset normal error.

The phantom 10 is provided with a display 160. The display 160 displays an average error, a deviation between an average error and a normal error in each pressure range, and whether or not the normal operation is performed. In this way, the user can easily determine whether the blood pressure monitor 20 is operating normally through the information provided on the display 160.

If the blood pressure monitor 20 needs to be calibrated as a result of the determination by the control unit 110 and it is necessary to restrict the use in clinical use, there is a possibility of leading to a medical accident if it is not appropriately sanitized. Therefore, countermeasures are needed.

3 is a view for explaining a process of forming an excessive pressure in the phantom 10 for the blood pressure monitor test according to the present invention.

Will be described with reference to FIG. 3 (a) is a view showing a situation in which the blood pressure meter 20 tightens the phantom 10 with the air band 35 mounted inside the cuff 30 for blood pressure measurement, FIG. 3 (b) 3 (c) shows a state in which the average error of the blood pressure measurement exceeds the preset normal error, and the phantom 10 And expanding in the cuff 30 due to excessive expansion.

In the present invention, in order to prevent the phantom 10 from being removed from the sphygmomanometer 20 when the average error of the phantom 10 exceeds a preset normal error, the transient pressure signal for expanding the phantom 10 is pressure- Unit 130 of FIG.

The pressure forming part 130 inflates the body 100 inside the cuff 30 to prevent the cuff 30 from being damaged. At this time, the pressure applied to the body 100 by the cuff 30 is measured by the pressure sensor 180 mounted on the surface of the phantom 10, and when the measured pressure is measured at a predetermined pressure or more, And controls to stop the pressure rise in the part (130).

This makes it possible to prevent the sphygmomanometer 20 requiring calibration from being injected into the clinic without any action.

4 is a view showing a blood pressure monitor calibration system according to the present invention.

Will be described with reference to FIG.

In the present invention, a blood pressure monitor calibrating system is constructed to automate blood pressure monitor calibrating tasks and improve work efficiency.

The blood pressure monitor calibration system includes a blood pressure monitor phantom 10 and a blood pressure monitor calibration / calibration server 40.

The phantom 10 for blood pressure monitor test is provided with a transmitter 170.

The transmitting unit 170 automatically transmits a blood pressure measurement result to the blood pressure monitor calibrating server 40 that manages the calibration and calibration of the blood pressure monitor 20, such as the measurement error of the blood pressure monitor, the average error, the blood pressure monitor serial number, .

This makes it possible to solve problems in the management of the blood pressure monitor due to the omission of the operator's record and the like.

In addition, the control unit 110 transmits a password for releasing the pressure of the excessively expanded phantom 10 to the cellular phone of the person in charge of calibrating the blood pressure monitor through the transmission unit 170. The controller 110 transmits a pressure release signal to the pressure forming unit 130 when the calibration manager receives the password and inputs the password to the data input unit 150.

As a result, the blood pressure monitor (20), which requires correction, can be injected into the clinic only by the action of the doctor in charge of calibration and correction.

On the other hand, the blood pressure monitor calibration server 40 uses the blood pressure monitor calibration data transmitted from the phantom 10 to transmit the calibration target blood pressure monitor list to the medical device management unit 50 on the calibration date. Therefore, the medical device management unit 50 can calibrate the blood pressure monitor 20 to be calibrated without any trouble.

5 is a flowchart of a blood pressure monitor testing method using the blood pressure monitor testing system according to the present invention.

Referring to FIG. 5, a blood pressure monitor testing method using the blood pressure monitor testing system according to the present invention will be described.
