Patent ID: 7611497

Claim:
A device for handling a catheter comprising: a valve body; a lever arm which is prestressed by means of a spring element and mounted pivotably on the valve body so as to be pivotable from a first end position into a second end position counter to the prestressing force of the spring element, a pressure piston which is received in the valve body and can be moved in a longitudinal direction by means of the lever arm in order to open a sealing element in the valve body when the lever arm is moved in the direction of the second end position, and a catch mechanism comprising an arresting arrangement with a front side having a catch nose and a rear side, and a catch tongue interacting with the catch nose in order to hold the lever arm in at least one catching position intermediate said first and second end positions, wherein the catch mechanism further comprises a guide surface adapted to guide the catch tongue from the front side to the rear side of said arresting arrangement when the second end position of the lever arm is reached, so that the catch tongue cannot enter into engagement with the catch nose and the spring element guides the lever arm along the rear side back into the first end position.
