普通的鼻填寒方法有以下缺点:阻塞了鼻呼吸,不能在出血部位用药。为克服上述缺点,作者设计了一种鼻填塞器。此填塞器由四个管组成:外管、内管和两个辅助管。内管的鼻内端带有由两层膜组成的囊。用探子弯曲内管可使囊位于所需的位置。可经一个辅助管向囊内注入气体或低温液体止血,还可经另一个辅助管向两层囊膜之间注入药物,经外膜上的小孔至出血部位止血。两个辅助管的开口和内外管之间 Ordinary nasal cold method has the following disadvantages: blocked nasal breathing, can not be used in the bleeding site. To overcome these shortcomings, the authors designed a nasal obturator. This obturator consists of four tubes: the outer tube, the inner tube and two auxiliary tubes. The nasal end of the inner tube has a capsule made up of two layers of membranes. Bending the inner tube with a probe positions the capsule in the desired position. Can be injected into the bladder via an auxiliary tube gas or cryogenic liquid to stop bleeding, but also through another auxiliary tube between the two capsule injection of drugs, the epicardial holes to the bleeding site to stop bleeding. Between the two auxiliary tube openings and the inner and outer tubes
