    • The invention relates to a membrane pump (700) comprising a first membrane (701) and a second membrane (702). A membrane interior space (704) with vacuum is formed between the first membrane (701) and the second membrane (702). The membrane interior space (704) comprises a first element (705) and a second element (707), wherein the first element (705) and the second element (707) are separated and electrically insulated by the vacuum in the interior space (704). The membrane pump (700) further comprises a resistance meter (709) which is configured to detect a resistance between the first element (705) and the second element (707) arising from a fluid leakage into the membrane interior space (704) due to rupture of the first membrane (701) and/or the second membrane (702).

    • Positive displacement pump system for the dispensing of droplets of liquid comprises a pump with a liquid-containing chamber (337) with a movable portion (313), an actuator (321) adapted to move said movable portion of said chamber for changing the volume of said chamber, a liquid outlet (343) in fluid communication with said chamber. A dispensing valve (344) for controlling flow through said liquid outlet and control means (326) for controlling said actuator and said valve are included. The system is characterized in that said actuator is a self-locking piezo-linear actuator in which the force required to produce a unit change in linear displacement of said movable portion of said chamber is substantially independent of the position of the actuator. Preferably the linear actuator is a walking piezo-motor. The pump may preferably be a bellows pump or a syringe pump. In a method to use the device the system pressure is stabilized before dispensing a plurality of droplets.

    • A disc pump includes an elliptical pump base (110) having at least one aperture (125) extending through the pump base (110). The pump base (110) comprises a first end wall (111) and a sealing surface (121). The disc pump includes an isolator (150) overlying the pump base (110) and having an isolator valve aperture (155) extending through the isolator (150) at or near the periphery of the isolator (150) and partially overlying a cavity (115) formed by the pump base (110) to form an outlet. In addition, the disc pump includes a valve flap (130) disposed between the pump base (110) and the isolator (150). The valve flap (130) has apertures (533) arranged about its periphery, beyond the periphery of the cavity (115) but underlying an isolator valve aperture (155). The valve flap (130) seals against the sealing surface (121) to close the pump outlet and prevent fluid from flowing from the outlet into the cavity (115) and flexes away from the sealing surface (121) to allow fluid to pass from the cavity (115) through the pump outlet.
    • 盘泵包括具有延伸穿过泵基座(110)的至少一个孔(125)的椭圆形泵基座(110)。 泵基座(110)包括第一端壁(111)和密封表面(121)。 盘式泵包括覆盖泵基座(110)并具有隔离器阀孔(155)的隔离器(150),隔离器阀孔(155)在隔离器(150)的周边处或附近延伸穿过隔离器(150),并且部分地覆盖空腔 )由所述泵基座(110)形成以形成出口。 此外,盘式泵包括设置在泵基座(110)和隔离器(150)之间的阀瓣(130)。 阀瓣(130)具有围绕其周边布置的孔(533),超过空腔(115)的周边,但位于隔离阀孔(155)下方。 阀瓣(130)密封在密封表面(121)上以关闭泵出口,并防止流体从出口流入空腔(115)并且偏离密封表面(121),以使流体从 空腔(115)通过泵出口。
