<P>PROBLEM TO BE SOLVED: To provide a compact portable pump that can be manually activated by a patient who receives treatment as needed, and can be activated again. <P>SOLUTION: A manually-activated reduced pressure treatment system 11 includes a substantially rigid housing, and an end cap slidably received by the housing. An inner chamber 51 is disposed between the end cap and housing, and a volume of the inner chamber is variable depending on the position of the end cap within the housing. The end cap is slidably movable between an uncompressed position at which the volume of the inner chamber is at a maximum value and a compressed position at which the volume of the inner chamber 51 is at a minimum value. A position indicating member is provided with the end cap and housing to indicate the position of the end cap relative to the housing at predetermined positions between the uncompressed position and the compressed position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
