项目摘要

In Japan, it was only after the 19th century that research concerning pathogens, the diseases they cause, and their cures, were discussed. Research about protective clothing for medical staff began in the latter half of the 20th century. Operation gowns with improved defense performance against various pathogens exist today in a wide variety. To investigate how selection of one of the many kinds that are available by hospitals is done, a questionnaire survey concerning operation gowns was carried out and the results were analyzed. The shift from gowns made from cotton fabric that could be repeatedly worn through washing and sterilization, to disposable gowns made from polyester, non-woven fabric was remarkable in the 1990's. Hospitals that used only disposable gowns comprised 53% of the total surveyed. There were many comments in the survey indicating a desire to shift completely to disposable types, from the perspective of safeguarding medical personnel. Defense performance improvement of the gowns and their performance evaluation were also requested.We have made a device which evaluates blood penetration resistance performance using an automatic pressurizing controller. It is an improvement on the device shown in the ASTM 1670 method. By adjusting a regulator and a proportion valve, the device can alter the time required to reach the maximum pressure of 2 psi in the ASTM method from 1 to 60 seconds. The blood penetration resistance performance of the cloth of 13 kinds of operation gowns was measured with this device. The experiment was conducted with an increase of pressure of 3.5kPa/sec, based on the ASTM 1670 method. Our goal is the development of operation gowns with a higher defense performance as a physical characteristic, especially with respect to blood penetration resistance.

在日本，直到世纪之后，才开始讨论病原体、它们引起的疾病及其治疗方法。医务人员防护服的研究始于世纪后半叶。具有针对各种病原体的改进的防御性能的手术服如今以各种各样的形式存在。为了解医院如何选择手术衣，对医院手术衣进行了问卷调查，并对调查结果进行了分析。在20世纪90年代，从可以通过洗涤和消毒反复穿着的棉织物制成的长袍到由聚酯无纺布制成的一次性长袍的转变是显着的。仅使用一次性手术衣的医院占调查总数的53%。调查中有许多评论指出，从保护医务人员的角度来看，希望完全转向一次性类型。此外，还要求提高防护服的防护性能，并进行性能评价。我们制作了使用自动加压控制器的抗血液渗透性能评价装置。这是对ASTM 1670方法中所示装置的改进。通过调节调节器和比例阀，该装置可以将达到ASTM方法中2 psi的最大压力所需的时间从1秒改变到60秒。用该装置对13种手术服面料的抗血液渗透性能进行了测试。基于ASTM 1670方法，以3.5kPa/sec的压力增加进行实验。我们的目标是开发具有更高防护性能的手术服，特别是在抗血液渗透方面。
