Patent attributes
The invention relates to a device for handling a catheter with an elongate valve body (12), a lever arm (26) which is, prestressed by means of a spring element and mounted pivotably on the valve body (12) so as to be pivotable from a first end position into a second end position (34) counter to the prestressing force of the spring element, a pressure piston (24) which is received in the valve body (12) and can be moved in the longitudinal direction by means of the lever arm (26) in order to open a sealing element in the valve body (12) when the lever arm (26) is moved in the direction of the second end position (34), and a catch mechanism (40) which has an arresting arrangement (42) and a catch tongue (50) interacting therewith in order to hold the lever arm (26) in at least one catching position. The catch mechanism (40) is designed in such a way that the arresting arrangement (42) and the catch tongue (50) come out of engagement when the second end position (34) of the lever arm (26) is reached, so that the spring element guides the lever arm (26) back into the first end position (FIG. 1).
