最近,英国医学科学家研制出一种微型高压水枪,可用来清洗病人动脉中的血凝块。在这一系统中,医生用一根橡皮导管将微型水管植入于病人体内,然后通过标准X线照射将水管定位在血块附近,通过6个小孔向血块喷射生理盐水,迫使血块进入橡皮导管,最后将血块从病人动脉中取出。 科学家们设计一个可以灵活移动的压力泵,以每平方英寸1万磅的压力将水压进微型水管。该系统非常小,医生可在直径2毫米的心脏动脉内清除血块,较小的血块可在两分钟内
Recently, British medical scientists developed a miniature high-pressure water cannons that can be used to clean blood clots in the patient’s arteries. In this system, the doctor uses a rubber catheter to implant the miniature water tube in the patient’s body. The tube is then positioned near the blood clot by standard X-ray irradiation. Physiological saline is injected through the six holes into the blood clot to force the blood clot into the rubber catheter , Finally remove the clot from the patient’s artery. Scientists have designed a flexible displacement pump that pumps water into a miniature hose at 10,000 pounds per square inch. The system is so small that doctors can remove blood clots in a 2 mm diameter heart artery and smaller blood clots in less than two minutes
