Abstract
A flow-through fluid reservoir includes a body with a first fluid port, a member movable within the body by an actuator to increase or decrease a volume of a chamber defined by a sidewall of the body. The actuator has a second fluid port. Movable member has a fluid path therethrough such that fluid ports are in fluid communication irrespective of the position of the movable member or the volume of chamber. A shaped slot on the shell of the actuator and a projection on the body cooperate to constrain relative movement of the body and actuator along a path corresponding to the shaped slot. The slot advantageously may include a stop intermediate therealong. A canted aspect of the slot may be used to initiate relative movement of the member within body. The body includes an end wall through which the first fluid port communicates. A shroud is defined by a coaxial extension of the sidewall beyond the end wall to surround the first fluid port, and gripping elements may be provided on the shroud. The projection may include a vent communicating into a space between a flexible barrier and an internal wall of the body. The slot may also have a one-way opening with a cammed roof. A clip may be provided for mounting the reservoir and includes a support member supporting a clip member which releasably receives the shroud and supports a mounting member such as for a sample site.
