    • Disclosed is a pneumatically-driven volume controlled bellows pump apparatus for oscillating liquid into a localized area of the human body, preferably methyl-tertiary butyl ether or another solvent, into the gallbladder. The pump includes a fluid reservoir in the form of an inverted syringe attached via a stopcock to the bellows. The bellows is attached via a second stopcock to a catheter also attached to a priming syringe. An inlet pinch valve is disposed between the bellows and the fluid reservoir and an outlet pinch valve between the bellows and the fluid receiver.To use the pump, a pigtail catheter with outlets in the pigtail is inserted into the desired area of the body, preferably a receptacle such as the gallbladder, to introduce a selected volume of liquid for gallstone dissolution. Liquid is infused into the receptacle by decompression of the bellows with the inlet but not the outlet valve open and then by compression of the bellows with the outlet but not the inlet valve open. Repeated infusion and aspiration is automatically accomplished by decompression and compression of the bellows with the inlet valve closed and the outlet valve open, or by compression and decompression of the bellows while the inlet valve is open and the outlet valve is closed alternated with compression and decompression while the inlet valve is closed and the outlet valve is open. Complete aspiration is accomplished by the use of a vacuum pump attached to the fluid reservoir. Also disclosed are syringe units and a transfer cap for use with the pump, together with a method for dissolving gallstones.
    • 公开了一种气动驱动的体积控制的波纹管泵装置,用于将液体振荡到人体的局部区域,优选甲基叔丁基醚或另一种溶剂进入胆囊。 该泵包括呈倒置的注射器形式的流体储存器,其通过旋塞连接到波纹管。 波纹管通过第二个旋塞连接到也连接到灌注注射器的导管上。 入口夹管阀设置在波纹管和流体储存器之间,以及在波纹管和流体接收器之间的出口压紧阀。 为了使用该泵,将在尾纤中具有出口的猪尾导管插入身体的所需区域,优选地插入诸如胆囊的容器中,以引入选定体积的用于胆结石溶解的液体。 通过用入口减压波纹管而不是出口阀打开,然后通过带有出口的波纹管压缩而不是入口阀打开,将液体注入到容器中。 重复输注和抽吸通过减压和压缩波纹管自动完成,入口阀关闭,出口阀打开,或通过压缩和减压波纹管,同时入口阀打开,出口阀关闭,与压缩和减压交替 而入口阀关闭,出口阀打开。 完全抽吸是通过使用连接到流体储存器的真空泵来实现的。 还公开了用于泵的注射器单元和转移盖,以及用于溶解胆结石的方法。
