摘要：
Embodiments of the present invention relate to the field of pressurized fluid delivery devices for use in medical procedures. In particular, a fluid delivery pump comprises at least one compressive member configured to apply a force to a fluid reservoir. The at least one compressive member is associated with a flexible envelope, such that the flexible envelope may move the compressive member. The flexible envelope may be substantially air-tight so that it may be pressurized. When a negative pressure is created inside the flexible envelope, the flexible envelope may change volume, applying a force to the at least one compressive member. The at least one compressive member may then apply a force to the fluid reservoir and the fluid is forced out of the reservoir.
