Abstract

Shipping Along with the aging of the total population, its importance is greater cause of stroke, which is one of the diseases are listed cerebral perfusion is about 80%,.ie that the flow of blood flowing to the brain is reduced as the cause. One of the most typical prophylaxis and treatment of these stroke is to enhance cerebral perfusion. There are several ways to increase cerebral blood flow are a therapy through drugs, through surgery and invasive NeuroFlo. NeuroFlo is to insert a catheter to which a balloon is attached into a patient's artery. However, since the method of enhancing conventional cerebral perfusion have been conducted mainly in invasive method, giving a burden to the patient, the problem of inducing a number of complications were noted. In this paper, an attempt to supplement the shortcomings of such invasive brain perfusion increase method, to provide a device to enhance the non-invasively brain perfusion.

전 인구의 노령화와 더불어 그 위험성이 커지는 질환 중 하나인 뇌졸중은 원인의 80%정도가 대뇌관류, 즉 뇌로 흐르는 혈류량이 줄어드는 문제로 발생한다. 이러한 뇌졸중의 가장 대표적인 예방법과 치료법중 하나가 대뇌관류를 증강하는 것 이다. 하지만 기존의 대뇌 관류 증강 방식이 주로 침습적인 방법으로 행해져 왔기 때문에, 환자에게 부담을 주고, 다수의 합병증을 유발한다는 문제점이 지적되었다. 이에 본 논문에서는 이러한 침습적 대뇌 관류 증강 방법의 단점을 보완하고자, 비침습적으로 대뇌관류를 증강 시키는 장치를 제안한다. 비침습적 대뇌 관류 증강장치는 환자의 사지에 압박패드를 장착한 후 각 사지의 혈압을 정확히 측정한 후, 측정된 혈압을 바탕으로 사지압박을 실시하여 대뇌관류증강을 이룬다. 이는 기존의 침습적 대뇌 관류 증강 방법과는 비교해 대뇌관류 증가율이 상대적으로 조금 부족할 수 있지만 환자에게 부담이 되지 않고 대뇌혈류량을 의미 있게 증가시키기 때문에 환자에게 선택적으로 사용될 수 있다.
