Abstract: A drug delivery pump drive which uses a linear piezoelectric motor to advance a syringe piston to deliver a liquid drug and a method thereof are disclosed. The pump drive, provided in a drug delivery pump, provides silent operation and very low energy consumption compared to electric motor-based drives. The small size of the motor helps also to reduce overall size of the pump drive and the resulting drug delivery pump.
Abstract translation: 公开了一种使用线性压电电动机推进注射器活塞以输送液体药物的药物输送泵驱动器及其方法。 药物输送泵中提供的泵驱动器与基于电动机的驱动器相比提供无声操作和非常低的能量消耗。 马达的体积小也有助于减少泵驱动器和所产生的药物输送泵的总体尺寸。

Abstract: A test strip container comprising a housing defining a cavity having a dispensing wall, a housing inlet, and a dispensing outlet is presented. The container may also comprise a lid mounted movably on the housing to define a primed position and an unprimed position therebetween. A cartridge may be provided within the cavity and holding a plurality of test strips. The cartridge may have a plunger entrance seal and a strip exit seal. A biasing member may be disposed within the cartridge urging the plurality of test strips towards the dispensing wall to be aligned with the dispensing outlet. A plunger may be provided, and oriented to open the plunger entrance seal through the housing inlet when the lid is in the primed position, and to urge a single test strip from the plurality of test strips through the strip exit seal of the cartridge and the dispensing outlet of the housing when the lid is transitioned from the primed position to the unprimed position.
Abstract translation: 提供了一种测试条容器,其包括限定具有分配壁,壳体入口和分配出口的空腔的壳体。 容器还可以包括可移动地安装在壳体上的盖子,以限定底漆位置和它们之间未被引导的位置。 可以在空腔内提供盒,并且保持多个测试条。 墨盒可以具有柱塞入口密封件和带出口密封件。 偏置构件可以设置在盒内,将多个测试条朝向分配壁推动以与分配出口对准。 可以设置柱塞,并且当盖处于初始位置时,定向成通过壳体入口打开柱塞入口密封件,并且通过盒的带出口密封件从多个测试条推动单个测试条,并且 当盖子从起始位置转移到未启动位置时,分配出壳体的出口。
