Abstract: This invention relates to a medical sewage treater, which consists of an article storing bag and water absorbing material, wherein the water absorbing material is a super absorbent polymer and is adhered to the inner wall of the article storing bag or set in the article storing bag. After medical sewage has flowed into the article storing bag, the water absorbing material absorbs water and expands so as to make the treated medical sewage become a colloid or solid of poor flowability such that it is convenient and safe in transportation and can effectively overcome the disadvantages in the prior art, such as uneasily stacking, leakage and thereby pollution during the transportation of the medical sewage. The invention is also applicable to collection and treatment of other deleterious sewage in daily life.

Abstract: The present invention provides an X-ray generator for achieving stereoscopic imaging effect and an X-ray device using the X-ray generator (101) as the X-ray source. The X-ray generator (101) can emit X-rays alternately from two positions the space of which conforms to the requirement for achieving stereoscopic imaging effect of the human beings.

Abstract: A radiopaque biodegradable vascular embolic microsphere comprises of a biodegradable material and a radiopaque material which can be both delivered to the vascular system, in which, the biodegradable material incorporates the radiopaque material to form granule structure. The embolic microsphere, readily visible under X-ray, can be delivered or drift with blood flow to a peripheral vessel or site, and can be manufactured using a simple process. A radiopaque biodegradable vascular embolic microsphere incorporating therapeutic agent(s) comprises of a biodegradable material, a radiopaque material, and therapeutic agent(s), which can be all delivered to the vascular system, in which, the biodegradable material incorporates the radiopaque material and the therapeutic agent to form granule structure. This embolic microsphere can be delivered to the targeted site under X-ray guidance, and then embolize the site, and release the therapeutic agent directly at the targeted site while degrading in vivo.

Abstract: An one-way valve for trocar is provided, which is mounted in the cavity of the end portion of the trocar sheath tube (2), and includes a V-shaped funnel construction (11) acted as the upper portion of the one-way valve (1), a slit (12) provided on the bottom surface of the V-shaped funnel construction (11), and a supporting body (13) acted as the lower portion of the one-way valve (1) and providing the sealing pressure to the slit (12). The supporting body (13) is connected to the outside of the inclined plane of the V-shaped funnel construction (11). Because the supporting body (13) which can provide the sealing pressure to the slit (12) is provided, when the one-way valve (1) is longitudinally compressed, the unique design of the supporting body (13) will provide sealing pressure on the slit (12). This is due to the spring back force formed when the valve is compressed.
