SAP Connector Air detection method for Intravenous fluids Medication error Prevention

摘要

More particularly, the present invention relates to a method for detecting air bubbles in a fluid connection tube by using an infrared light emitting portion and a light receiving portion, The present invention relates to a method for detecting air bubbles in a vein, and more particularly, to a method for detecting air bubbles in a vein, which can reliably generate 3D bubble images using a multi-image and provide the bubbles to an administrator. The present invention provides a method for detecting air in a fluid connection tube for preventing intravenous infusion errors, An infrared light emitting step (S100) for emitting infrared light to the liquid connection tube by the infrared light emitting part; An infrared ray receiving step (S200) for receiving infrared rays by the infrared ray receiving unit; An image analysis step (S300) for determining whether air bubbles have been formed by capturing an image in multiple angles by providing an operation signal to the camera unit when air bubbles are detected by the central processing unit; A boundary surface extracting step (S400) for extracting a boundary surface when it is determined by the central processing unit as an air bubble; An air bubble determination step (S500) for determining whether there is air bubbles by determining whether a color different from blood color exists in the inside of the interface by the central processing unit; When it is determined by the central processing unit that there is another color, images taken in the front, back, top and bottom of the image taken at the same time as the corresponding air bubble image of the images taken at various angles are obtained, An air bubble determination step (S600) for precise determination through an image; A three-dimensional air bubble image generation step (S700) for generating three-dimensional bubble images by acquiring forward, backward, upside, and downside images when the air bubble is detected as a result of precision determination by the central processing unit; And an air bubble informing step (S800) for transmitting the 3D bubble image to the representative terminal and informing the three-dimensional bubble image to the representative terminal.
