휴대용 디지털 압통기Portable digital tender
본 발명은 휴대용 디지털 압통기에 관한 것이다.The present invention relates to a portable digital tender.
최근 통증평가가 체온, 혈압, 맥박, 호흡에 이어 환자를 치료하는데 중요한 징후로 인식되고 있다.Recently, pain assessment has been recognized as an important symptom for treating patients following body temperature, blood pressure, pulse rate, and breathing.
통증에 대한 치료를 위해 환자의 통증 정도를 객관적이고 정량적인 수치로 측정하는 것이 필요하다.For the treatment of pain, it is necessary to measure the pain degree of the patient by objective and quantitative figures.
하지만 통증은 환자가 주관적으로 느끼는 부분이라 환자의 통증을 객관적인 데이터로 표시하는 데 한계가 있다. However, since pain is a subjective part of the patient, there is a limit in displaying the pain of the patient as objective data.
이러한 객관적인 통증의 평가 방법으로는 현재는 눈썹, 이마 및 눈꺼풀의 움직임을 관찰하여 통증 정도를 평가하는 방법 및 환자가 느끼는 통증의 정도를 1단계~10단계로 구분하고 환자가 느끼는 통증의 정도가 얼마인지를 물어서 표시하고 있는 방법이 주로 사용되고 있으나 환자에 따라 주관적으로 통증을 느끼는 정도가 달라 통증에 대한 객관적인 측정이 안되고 있다.These objective pain assessment methods are currently used to evaluate the degree of pain by observing the movement of the eyebrows, forehead and eyelids, and the degree of pain felt by the patient in 1 to 10 steps. The method of asking and displaying cognition is mainly used, but subjective pain is different from subject to patient, and objective measurement of pain is not possible.
피부에 압력을 가했을 때에 느끼는 통증을 측정하는 장치를 일반적으로 통각계 또는 압통기라 한다. 종래의 압통기는 아날로그 압통기와 전자 압통기로 대별된다. 종래 아날로그 압통기는 측정자가 실시간으로 표시되는 압통기의 측정값을 정확히 기록하기 어려우며 미세한 압력에 의한 통증은 측정하기 어려웠다. 또한 종래 전자 압통기는 압통 측정 프로브, 스위치 및 프린터 등이 선으로 연결되어 있어 사용하기 불편하고, 측정 데이터를 저장 할 수 없으며, 정확한 통증 부위에서의 압통 측정이 어려운 단점이 있다.A device for measuring the pain felt when pressure is applied to the skin is generally called a pain sensor or a tender. Conventional presses are roughly classified into analog presses and electronic presses. Conventional analog pressure gauges are difficult for a measurer to accurately record the measured value of a pressure gauge displayed in real time, and pain due to minute pressure is difficult to measure. In addition, the conventional electronic tender, it is inconvenient to use, can not store the measurement data, it is difficult to measure the tenderness in the accurate pain area is connected to the line of the pressure measurement probe, switch and printer, and the like.

먼저, 도 1을 참고로 하여, 본 발명의 한 실시예에 따른 휴대용 디지털 압통기에 대해 설명한다.First, with reference to FIG. 1, a portable digital pressurizer according to an embodiment of the present invention will be described.
도 1을 참고로 하면, 도 1은 본 발명의 바람직한 일 실시예에 의한 휴대용 디지털 압통기를 설명하기 위한 블록도로서, 압력센싱부(100), A/D 변환기(200), 데이터 분석부(400), 디지털 제어부(300), 데이터 표시부(500), 스위치부, 파워다운모드 제어부(600)를 구비한다.Referring to FIG. 1, FIG. 1 is a block diagram illustrating a portable digital pressure cylinder according to an exemplary embodiment of the present invention, which includes a pressure sensing unit 100, an A / D converter 200, and a data analyzing unit 400. ), A digital controller 300, a data display unit 500, a switch unit, and a power down mode controller 600.
도 1을 참조하면 압력센싱부(100)는 압력에 따른 전기적 신호를 출력한다. 이를 위하여 압력센싱부(100)는 압력센서(100a), 압력센서 구동부, 전류-전압 변환부(100b), 증폭부(100c), 저역통과 필터(100d)를 구비한다. 압력 센서(100a)로는 지름10의 활성감지영역내에 힘을 인가하였을 때 반응하여 0 ~ 25lb (111N)까지의 압력을 측정할 수 있는 플렉시포스 압력센서(Flexiforce Pressure Sensor A101 : Flexiforce)를 사용할 수 있으며 플렉시포스 압력센서는 압력이 없을 때 높은 저항 값(수)이며 압력을 가하면 저항값이 내려가며(수) 작은 압력에도 저항 값의 변화량이 크다. 압력센서 구동부는 압력센서를 구동시켜 가해진 압력에 따라 전류 신호를 출력하게 하며, 전류-전압 변환부(100b)는 이 출력된 전류신호를 전압 신호로 변환하고 증폭부(100c)에서 이를 소정의 증폭률로 증폭한다. 상기 증폭부(100c)의 출력신호로부터 잡음을 제거하기 위해 10Hz의 차단주파수를 갖는 저역통과필터(100d)를 거친다.Referring to FIG. 1, the pressure sensing unit 100 outputs an electrical signal according to pressure. To this end, the pressure sensing unit 100 includes a pressure sensor 100a, a pressure sensor driver, a current-voltage converter 100b, an amplifier 100c, and a low pass filter 100d. As the pressure sensor 100a, a Flexiforce pressure sensor A101 (Flexforce), which can measure a pressure from 0 to 25 lb (111 N) in response to a force applied in the active sensing area of diameter 10, can be used. Flexiforce pressure sensors have a high resistance value (male) when there is no pressure, and the resistance decreases when a pressure is applied (male). The pressure sensor driver drives the pressure sensor to output a current signal according to the applied pressure, and the current-voltage converter 100b converts the output current signal into a voltage signal and the amplifier 100c converts the current signal into a predetermined amplification factor. Amplify. In order to remove noise from the output signal of the amplifier 100c, the low pass filter 100d having a cutoff frequency of 10 Hz is passed.
A/D변환기(200)는 압력센싱부(100)의 출력신호를 디지탈 신호로 변환하여 데이터 분석부(400)로 출력한다.The A / D converter 200 converts the output signal of the pressure sensing unit 100 into a digital signal and outputs the digital signal to the data analysis unit 400.
데이터 분석부(400)는 마이크로콘트롤러로 이루어져 있으며, A/D 변환기(200)의 출력신호를 힘(kg)에 대한 값으로 환산한다. 이때 환산은 수학식 1에 의해 구해진다.The data analyzer 400 includes a microcontroller, and converts the output signal of the A / D converter 200 into a value for force kg. At this time, the conversion is obtained by the equation (1).
[수학식 1][Equation 1]
y=2.3595xy = 2.3595x
(단, y는 힘(kg)이고, x는 A/D 변환기의 출력신호인 전압값)(Where y is force (kg) and x is voltage value which is output signal of A / D converter)
여기서 계수인 2.3595는, A/D변환기(200)의 전압값을 힘으로 환산하기 위한 교정곡선으로부터 구해진 기울기이다. 즉, 데이터 분석부(400)에서 A/D변환기(200)의 출력신호인 전압값을 힘으로 환산하기위해서 환산(교정)을 위한 수학식이 필요하며 이는 교정곡선으로부터 구해진다. 교정곡선은, 도 2와 같이, 각각 100g, 500g, 1kg, 2kg, 5kg의 분동과 전자저울을 사용하여 힘에 대한 전압값을 측정하며, 이렇게 해서 얻어진 그래프(교정곡선)에서 얻어진 기울기가 상기 수학식 1의 기울기이다.The coefficient 2.3595 is a slope obtained from a calibration curve for converting the voltage value of the A / D converter 200 into a force. That is, in order to convert the voltage value, which is the output signal of the A / D converter 200, into a force in the data analyzer 400, a mathematical equation for conversion (calibration) is required, which is obtained from a calibration curve. The calibration curve, as shown in Figure 2, using a weight and an electronic balance of 100g, 500g, 1kg, 2kg, 5kg, respectively, to measure the voltage value for the force, the slope obtained in the graph (calibration curve) obtained in this way is It is the slope of equation 1.
데이터 표시부(500)는 데이터 분석부(400)의 출력신호를 표시하는데, 압통측정값과 압통측정그래프를 동시에 표시한다. 압통측정그래프에는 1초마다 1kgf/cm2씩 압력을 증가시키는 조건을 만족하게하기 위한 기준선과 실제 측정된 압통치를 표시한다. 이 기준선을 그래프상에 제공함으로써, 매초 마다 일정하게 소정의 값으로 증가된 압력을 사용자에게 제공할 수 있다.The data display unit 500 displays an output signal of the data analyzer 400, and simultaneously displays a pressure measurement value and a pressure measurement graph. The tenderness graph shows the baseline and actual measured tenderness values to satisfy the condition of increasing pressure by 1 kgf / cm 2 per second . By providing this baseline on a graph, it is possible to provide the user with an increased pressure to a predetermined value constantly every second.
파워다운모드 제어부(600)은 시작스위치(701)가 온(ON)되면 전원부를 슬립모드에서 작동모드로 변경하고 시작스위치(701)가 오프(OFF)되면 전원부를 작동모드에서 슬립모드로 변경한다.The power down mode control unit 600 changes the power supply unit from the sleep mode to the operation mode when the start switch 701 is ON, and changes the power supply unit from the operation mode to the sleep mode when the start switch 701 is OFF. .
또한, 알람부(800)는 매초마다 부저를 울리어 데이터 표시부에 표시된 기준선에 맞추어 일정하게 압력을 사용자에게 제공하도록 돕는다.In addition, the alarm unit 800 helps to provide the user with a constant pressure in accordance with the reference line displayed on the data display unit, buzzing the buzzer every second.
