对各种神经功能失常的患者进行诊断和治疗时,测定颅内压是很重要的。纽约大学神经外科Alvin Wald博士率领的小组发明了一种监视脑膜外颅内压的新技术。过去的各种方法有种种缺点,例如脑内物质和外部积液之间有感染的危险;不适应于幼儿的软性头盖;有触电的潜在危险等。上述新技术所使用的装置就没有这些缺点,并已达到了实用的阶段。新的装置是由埋植式传感器和监视器二部分组成。埋植式传感器是一个厚1毫米、直径10毫米的气囊,内部充填空气,可以压缩或膨胀,气囊内装着一个镜子,镜子可以相应于内外压力变化而进行转动。监视器有
For a variety of neurological dysfunction in patients with diagnosis and treatment, determination of intracranial pressure is very important. A team led by Dr. Alvin Wald, neurosurgeon at New York University, invented a new technique to monitor extracranial intracranial pressure. Various methods of the past have various disadvantages, such as the risk of infection between the brain substance and the external fluid, the soft head cover that is not suitable for young children, and the potential danger of electric shock. The devices used for these new technologies do not have these disadvantages and have reached a practical stage. The new device is composed of embedded sensors and monitors. The implantable sensor is a 1 mm thick, 10 mm diameter balloon filled with air that can be compressed or expanded. The balloon contains a mirror that mirrors the internal and external pressure changes. Monitor there
