The infusion of fluid and blood is necessary in the ward, operating room, recovery room, neonatal room, etc. for nutrition and blood supply to the patient, but air bubbles generated during infusion of fluid and blood circulate along the artery or vein. Serious illnesses occur and there is also a risk of death. In this paper, we propose a medical bubble detection system, a bubble detection system, a bubble detection alarm system, and a communication method in order to develop a safer fluid and blood injection system in the existing system, which is detected by a medical staff monitoring system or an ultrasonic bubble detection sensor In this study, infrared rays are transmitted to a tube through a tube for injecting fluid or blood into a patient, infrared rays transmitted by an infrared ray emitting section are received, and the amount of light is measured in real time. Based on the data, we study how to detect and analyze the presence of bubbles in fluid and blood.

In this paper, an ECG-NIBP patient monitor is designed. This is an essential equipment to measure and monitor patient's physical condition - electrocardiogram(ECG) wave, heart rate(HR), and noninvasive blood pressure(NIBP) - in ICU, CCU, and operating room. The ECG is an electrical waveform produced by relaxation and contraction of the cardiac muscle. Most physicians diagnose patient's cardiac states from ECG pattern. A blood pressure is one of the clinical indexes measured in a emergency room or operating room. In this paper, the blood pressure is measured in artery by using the nonivasive oscillometric method. The developed patient monitor was inspected and compared with other instruments in operating rooms. The results were 1bpm of maximum difference in the heart rate, 15mmHg in the systolic pressure, 16mmHg in the diastolic pressure, and 25mmHg in the mean blood pressure. But the total results were 0.15bpm of the mean difference in the heart rate, 5mmHg in the systolic pressure, 10mmHg in the diastolic pressure, and 9mmHg in the mean blood pressure. The designed ECG-NIBP patient monitor can measure the ECG wave, HR, and BP. And the multi-tasking module of pulse oximetry . respiration . temperature monitor will be added in the near future.

The present study investigated the actual conditions of physical therapy rooms at long-term hospitals in Korea and conducted a comparative analysis to develop an efficient floor plan and facility improvement measures. 1. At hospitals surveyed, physical therapy services were used at a high frequency but they did not have enough space for rehab treatment and long paths of patient flow were found to make patient management inconvenient. Therefore, physical therapy units should be conveniently located both in terms of distance and direction so as to be accessible from patient rooms or wards. The space should be organized in a concentrated layout for efficiency of physical therapy, and floor planning for therapy units should ensure the best possible viewing angle to therapists. 2. With regard to the disease characteristics of patients, many physical therapy rooms were in difficult circumstances because of poor facilities, so they need to secure skilled personnel, supplement apparatuses and equipment and have rooms for functional recovery, hydrotherapy and operation treatment. In addition, each of the curtained or partitioned areas for treatment should be set up with consideration for the amount of space taken up by medical equipment. The area under each bed should be designed for patient convenience so that it can be used as storage space for patient's belongings and shoes. 3. Patients complained about the lack of physical therapy space, resting places or exercise areas and demanded the expansion of rehab programs and facilities. Physical therapy facilities need to be improved for patient privacy and effective natural ventilation. 4. At most of the long-term hospitals surveyed, physical therapy units were found to have small areas and treatment equipment and devices were insufficient compared to the number of patients. Therefore, it is required to secure more space (at least 138.24 sq. meters per 100 beds) and improve facilities for better physical therapy services.

In this study, electromagnetic fields emitted from the various environment in the hospital were measured. Measurement spot was patients' head. To monitor how much magnetic fields are emitting from operation room, monitoring device was attached to 19 anesthesiologist and monitoring lasted 8 hours. We also took a measurement from various medical devices. Devices include ESWL, PET, MRI, CT, Gamma knife, X-ray, Angiogram, Echocardiogram, Upper GI and Linear Accelerator. Electromagnetic fields were measured from 10 spots from each of 5 patient waiting room. As a results, there were no places showing risk of high exposure. All the measurement values were below the reference levels for general public exposure to time varying electric and magnetic fields which is issued by ICNIRP.

The azygos vein sometimes merges abnormally across the right upper lobe of the lung and it hangs at the lower edge of a membranous septum, called the meso-azygos. The septum invaginates the lobe and makes a fissure. The smaller medial part of the right upper lobe is called an azygos lobe. A 16-year-old male patient was diagnosed with right-sided pneumothorax, and a closed thoracostomy was done in the emergency room. During elective wedge resection including the bulla, the meso-azygos, abnormal azygos vein, and azygos lobe were detected. We reviewed the computed tomography images and found that the azygos lobe had re-expanded laterally, not medially, to the meso-azygos after the closed thoracostomy in the emergency room. The patient had been diagnosed with left-sided pneumothorax a year ago, and no one noticed the azygos lobe at that time. We report the intraoperative findings and comparative images of a migratory azygos lobe.

The color planning in the hospital could influence the patient's improvement and lead the users from room to room. This study shows the data of present colors used in the hospitals. In order to get the data, we surveyed and analyzed the current color usages of the present interior of hospitals by the individual data from the projectors. The color scheme is analyzed by the rooms which are the common room, the ward, and the examination room along the projectors. It is also analyzed by the finishes of the hospitals, and is addressed to the present color scheme by the means of the hue value, and chroma. The color scheme in the interior design of hospital is an important factor for the hospital users. It has to more sincerely considered to use colors effectively in the hospital interior since people use their organ of vision greatly when they sense things. According to the data, this study is proposed to the effective color plan which is considered psychologically and emotionally about the human activities, in the interior design of hospitals for the future.

A 47-year-old man was referred to the operating room to treat a dentigenous cyst of the mandibular bone. Initial assessment of the airway was considered normal. However, after the induction of anesthesia, we could not intubate the patient due to severe distortion of the glottis. Fiberoptic bronchoscopy and video laryngoscopy were not effective. Intubation using a retrograde wire technique was successful. After the conclusion of surgery, the patient recovered without any complications. Subsequent magnetic resonance imaging of the patient's neck showed a $6{\times}4{\times}8.6cm$ heterogeneous T2 hyperintense, T1 isointense well-enhancing mass in the prestyloid parapharyngeal space. The patient was scheduled for excision of the mass. We planned awake intubation with fiberoptic bronchoscopy. The procedure was successful and the patient recovered without complications. Anesthetic induction can decrease the muscle tone of the airway and increase airway distortion. Therefore, careful airway assessment is necessary.
