The biggest problem in imaging medicine is the occurrence of light reflection in the imaging process for lesion diagnosis. The formation of light reflection obscures the diagnostic field of the lesion and interferes with the correct diagnosis of the observer. The existing method has the inconvenience of performing a diagnosis in a state in which light reflection is suppressed by adjusting the direction angle of the camera. This paper proposes a method for rotating a linear polarization filter to remove light reflection in a diagnostic imaging camera. Vertical polarization and horizontal polarization are controlled through the rotation of the filter, and the polarization is adjusted to horizontal polarization. The rotation angle of the filter for horizontal polarization control will be 90°, and the vertical and horizontal polarization waves induce a 90° difference from each other. In this study, light reflection can be effectively removed during the imaging process, and light reflection removal can secure the field of view of the lesion. The removal of light reflection can help the observer’s accurate diagnosis, and these results are expected to be highly reliable and commercialized for direct application in the field of diagnostic medicine.

Background Intravenous fluid treatment is the most common way to take care of inpatients. Because of the global pandemic, the number of inpatients is increasing rapidly, leading to constant demand in the contactless system. Purpose In this article, we suggest a web-based intravenous fluid treatment monitoring platform in the nursing station to unburden the medical staff’s workload.

Background: After surgery, the exudation at a surgical site can cause complications and infections. The exudation is periodically removed through a Jackson-Pratt (JP) drain while maintaining a negative pressure in the JP bulb. However, the JP drainage tube may be clogged due to blood clotting. Thus, the periodic management of the JP drain is essential. In particular, the postoperative management of the JP drain includes squeezing and stripping it. In this study, we proposed a JP drain auxiliary system that can perform automatic stripping to assist specialists and nurses. Methodology: The proposed system was designed based on pre-experimental measurements and operated as a gripping and rolling device. Experimental Results: Twenty experiments were performed, and an average stripping efficiency of 93.8% was obtained. Conclusions: Consequently, we think that the proposed auxiliary system can automatically contribute to increase working efficiency for specialists and nurses.
