Devices and systems disclosed herein may include a negative pressure pump that includes a reservoir defining a lumen and a longitudinal axis, a piston, and a drive assembly comprising a spring. Motionof the spring may move the piston along the longitudinal axis of the reservoir to create a negative pressure within the reservoir. Methods of manufacturing a negative pressure pump and using a negative pressure pump to remove fluid from a target site are also described. 本文中公开的装置和系统可包括负压泵；该负压泵包括限定腔体和纵向轴线的贮室、柱塞、及包括弹簧的驱动组件。弹簧的运动可使柱塞沿贮室的纵向轴线移动从而在贮室内部产生负压。也描述了制造负压泵和利用负压泵从靶部位排除体液的方法。
