    摘要: Disclosed are a gastrointestinal tract ultrasonic examination aided developer and a preparation method therefor. The aided developer is mainly composed of a thickener, an osmotic pressure regulator, a solid contrast, a defoamer and a flavoring agent, wherein a density of the solid contrast is the same as that of aided developer liquid. The present disclosure adopts the solid contrast with a special particle size, making a distribution area present a more obvious homogeneous high echo after the aided developer reaches the stomach and intestine, and a good aided developing effect is achieved.

    摘要: The present disclosure relates to a medical silicon rubber having high mechanical property and a preparation method thereof. The medical silicon rubber comprises the following raw materials in parts by weight: 50˜90 parts of silicon rubber, 10˜50 parts of polyurethane, 10˜50 parts of fillers, 2˜6 parts of hydrogen-containing silicon oil and 2˜5 parts of a vulcanizing agent. The preparation method comprises: evenly mixing a part of fillers with silicon rubber in an internal mixer for later use, and evenly mixing the other part of fillers with polyurethane in the internal mixer; and mixing the mixed polyurethane on an open type rubber refining machine, then successively adding hydrogen-containing silicon oil, the evenly mixed silicon rubber and the vulcanizing agent into the open type rubber refining machine many times by small portions, and finally vulcanizing the mixed rubber on a plate rubber vulcanizing machine for 5˜15 min at 150˜190° C.
