본 발명은 점적 챔버 또는 튜브에 설치된 광학 센서를 이용하여 환자에게 링거액 주입 상태에 대한 다양한 정보를 제공해주는 링거액 주입 상태 모니터링 장치에 관한 것이다.The present invention relates to a Ringer's fluid injection state monitoring device that provides a variety of information on the Ringer's fluid injection state to the patient using an optical sensor installed in the drop chamber or tube.
종래의 링거액 주입 상태 모니터링 장치로는,As a conventional ringer liquid injection state monitoring device,
광센서를 감지 수단으로 이용하는 장치는 광센서의 조도 변화를 감지하는 방식으로 링거액의 색상, 투명도, 주변의 밝기에 영향을 받으며, 튜브에는 설치할 수가 없으며 점적 챔버가 기울어진 경우에도 사용할 수가 없고, 더구나 점적 챔버 외각에 장치가 설치되기 때문에 점적 챔버 내부를 보기 위한 시야에 영향을 주게 되고,
링거액 내부에 전극을 삽입시켜 전류를 감지토록 하는 장치는 이물질, 세균 등의 오염에 노출되고,
정전용량센서를 사용하는 방식은 고감도 센싱 능력을 구현하기 위해선 제작 비용이 너무 많이 들고 부피가 커지는 단점이 있다.Devices that use light sensors as sensing means are affected by the color, transparency, and ambient light of the Ringer's solution by detecting changes in the illuminance of the light sensors, and cannot be installed in the tube, even when the drop chamber is tilted. Because the device is installed outside the drip chamber, it affects the view to the inside of the drip chamber,
The device to detect the current by inserting the electrode inside the Ringer's solution is exposed to contamination such as foreign substances, bacteria,
The method using the capacitive sensor has the disadvantage of being too expensive and bulky to realize high sensitivity sensing capability.
따라서, 본 발명은 상술한 바와 같은 종래의 링거액 주입 상태 모니터링 장치들의 문제점을 해결하기 위해 안출된 것으로,Therefore, the present invention has been made to solve the problems of the conventional ringer liquid injection state monitoring apparatus as described above,
본 고안의 목적은 링거액의 종류 및 주변 밝기에 영향을 덜 받고 오염의 염려가 전혀 없으며 소형이면서 제작 비용이 적게 드는 링거액 주입 상태 모니터링 장치를 제공하는 데에 있으며, 이하 첨부된 도면에 의거 본 발명의 구성 및 작용을 상세히 설명하면 다음과 같다. An object of the present invention is to provide a ringer liquid injection state monitoring device that is less affected by the type of ringer liquid and ambient brightness, there is no concern about contamination, and is small and low in manufacturing cost, and according to the accompanying drawings of the present invention The configuration and operation will be described in detail as follows.
본 발명에서 예시되는 실시 예 1은 도 1에서 도시된 바와 같이, 점적 챔버(5) 외각에 설치된 광학 센서(CCD 이미지 센서, CMOS 광학 센서 등과 같이 이미지를 전기 신호로 변환하는 센서)(1), 초점 렌즈(2), 발광 다이오드(3)로 구성되어지며, 링거액 방울(4)이 광학 센서(1)와 발광 다이오드(3) 사이를 통과하게 되면 방울의 이미지는 초점 렌즈(2)를 통해 광학 센서(1)에 촬상(撮像)된다. 촬상된 이미지는 디지털 신호 처리 장치(7)에 의해 전기 신호로 변환되어지게 되며 마이크로프로세서(8)는 전기 신호를 분석하여 링거액 방울의 낙하 시간 간격 및 방울의 용적을 계산한다. As illustrated in FIG. 1,
도 2는 가로 세로 각각 6 픽셀(pixels)의 총 36 픽셀을 가진 광학 센서를 사용했을때, 링거액 방울이 광학 센서를 통과하는 동안에 방울이 광학 센서에 촬상되는 모습을 예시로 보여준다. 도 2의 A는 링거액 방울이 광학 센서(1)와 발광 다이오드(3) 사이를 진입하기 시작하는 시점의 광학 센서 픽셀들의 촬상 상태를 보여주며, 방울이 광학 센서 앞을 거의 통과하게 되면 I와 같은 픽셀 촬상 상태가 나타나게 된다. 광학 센서의 픽셀에 촬상되는 방울 이미지의 형상 및 위치에 따라 광학 센서에서 발생하는 전기 신호의 특성이 달라지기 때문에, 이러한 변동 전기 신호를 마이크로프로세서(8)로 분석하여 방울의 낙하 시간 간격과 방울의 용적을 계산하게 된다.FIG. 2 shows an example in which the droplets are captured by the optical sensor while the Ringer's droplet passes through the optical sensor when using an optical sensor having a total of 36 pixels of 6 pixels each. FIG. 2A shows the imaging state of the optical sensor pixels at the time when the Ringer's solution droplet starts to enter between the
본 발명에서 예시되는 실시 예 2는 도 3에서 도시된 바와 같이, 튜브의 외각에 광학 센서(1), 초점 렌즈(2), 발광 다이오드(3)을 설치하여, 튜브 속을 흐르는 링거액의 이미지를 광학 센서에 촬상되도록 하여, 상기 실시 예 1과 같은 방식으로 촬상된 이미지를 디지털 신호 처리 장치(7)로 분석하여 링거액 유속을 마이크로프로세서(8)에 의해 계산하는 방안을 보여준다. In Example 2 illustrated in the present invention, as shown in FIG. 3, an
본 발명에서 예시되는 실시 예 3은 도 4에서 도시된 바와 같이, 점적 챔버의 외각에 반사 거울(12)을 설치하여 발광다이오드(3)의 빛이 거울(12)에 반사된 후 광학 센서(1)에 도달하도록 하는 방안을 보여준다.As illustrated in FIG. 4, in
이상과 같이 본 발명에 의하면 광학 센서를 점적 챔버 또는 튜브의 외각에 설치하는 방법에 의해 링거액의 주입 속도 및 주입량을 계산할 수 있으므로,As described above, according to the present invention, the injection speed and the injection amount of the Ringer's solution can be calculated by the method of installing the optical sensor in the outer chamber of the dropping chamber or the tube.
환자의 이동 중에 발생하는 원치 않는 링거액 주입 속도의 변화를 감지하여 경보 신호를 환자에게 통보할 수 있으며,It can detect the unwanted change in Ringer's fluid infusion rate during the patient's movement and notify the patient of the alarm signal.
원하는 만큼의 링거액이 주입되었을 때 경보 신호를 환자에게 보낼 줄 수 있으며,It can alert the patient when the amount of Ringer's solution is given.
링거액이 모두 소진되었을때 이를 경보 신호로 환자에게 통보해 줄 수 있는 효과가 제공된다.When the Ringer's fluid is used up, it is possible to notify the patient by an alarm signal.
