    • The invention relates to a low-frequency focus ultrasound-generating device and its application in clinical physical therapy to cause embolism of new blood vessels of tumor. The device comprises a hand grip, an ultrasound output, a half-ellipsoid reflector, and a water sack. The half-ellipsoid reflector is disposed on the forward end of the hand grip. The rear part of the ultrasound output is set in the hand grip, while the front part of the ultrasound output is set in the half-ellipsoid reflector. On a lateral side of the ultrasound output in the front of the hand grip, there is a tie-in for water infusion and gas exhaust. The inner portion of the tie-in is in communication with the inner portion of the half-ellipsoid reflector. At an opening on the forward end of the half-ellipsoid reflector is disposed the water sack. The front face of said ultrasound output lies in a focus of the half-ellipsoid reflector.
    • 本发明涉及一种低频聚焦超声波发生装置及其在临床物理治疗中的应用,以引起肿瘤新血管栓塞。 该装置包括手柄,超声波输出,半椭圆反射器和水袋。 半椭圆反射器设置在手柄的前端。 超声波输出的后部设置在手柄中,而超声输出的前部设置在半椭圆反射器中。 在手柄前方的超声波输出的侧面,有一个接合用于输水和排气。 连接件的内部与半椭圆反射器的内部连通。 在半椭圆反射器的前端的开口处设置水袋。 所述超声输出的前表面位于半椭圆反射器的焦点。

    • A tracing or marking isotope micro-bubble reagent with targeting substance, the combination or mixture of ultrasonic micro-bubble imaging reagent with tracing or marking isotope. The tracing or marking isotope includes generally medical used isotopes. The micro-bubble reagent includes fluoro-carbon type, medical salt water type, semi lactose bubble liquid type, envelope bubble liquid type and carbon dioxide generating type. Large molecule substance is selected as the carrier of ultrasonic reagent to wrap, stick, stabilize and carry the bubbles. The tracing or marking isotope micro-bubble reagent with targeting substance is applied to position the tumor area in the treatment of tumor by using low frequency, low energy ultrasonic to induce the cavitation effect of micro-bubbles to form thrombus embolus in blood vessels, Meanwhile, radial β isotope is applied to radiate the tumor cells by using the ionizing radiation biological effect thereof.
    • 具有靶向物质的跟踪或标记同位素微泡试剂,超声微泡成像试剂与追踪或标记同位素的组合或混合物。 跟踪或标记同位素一般包括医学上使用的同位素。 微泡试剂包括氟碳型,医用盐水型,半乳糖气泡液型,包膜泡沫液型和二氧化碳生成型。 选择大分子物质作为超声波试剂的载体包裹,粘附,稳定和携带气泡。 采用靶向物质追踪或标记同位素微泡试剂,采用低频,低能量超声波,将肿瘤区域定位于肿瘤治疗中,诱导微泡形成血栓形成血栓栓塞的气穴作用,同时 应用径向β同位素通过其电离辐射生物学效应辐射肿瘤细胞。
