Measuring device, urological instrument and receiving device

A urological instrument that includes a measuring device (10) for recording a peak level of a liquid flow from a user, the urological instrument comprising:

• a receiving member (20) for receiving the liquid flow;
• the measuring device (10) for recording the peak level of the liquid flow;
• a collecting device (30) for collecting said liquid flow,
• wherein said receiving member connects to said measuring device and said measuring device connects to said collecting device,
• wherein the measuring device (10) includes
• i) an inlet (2) opening into an inlet chamber (3), wherein the inlet chamber receives the liquid flow through the inlet opening;
• ii) a recording chamber (4) that communicates with the inlet chamber (3) through a passage opening (6) to allow said liquid flow to accumulate, at least temporarily, up to a level in said recording chamber, and
• an outlet chamber (7) that is adjacent said recording chamber (4),
• wherein said recording chamber is separated from said inlet opening for direct liquid communication by an intermediate wall that leaves said passage opening (6) on a side remote from said inlet opening (2);
• wherein said recording chamber comprises at least one outflow opening (9, 9′) to allow a discharge of said liquid from the recording chamber into the outlet chamber up to a peak level,
• wherein said at least one outflow opening (9,9′) comprises a series of outflow openings (9,9′) configured to allow a partial discharge of said liquid from said recording chamber into said outlet chamber at consecutive indication levels;
• and
• indicator means provided in said recording chamber that leave an indication of said peak level,
• wherein the indicator means are arranged to each of said series of outflow openings to register a liquid level up one of said indication levels,
• wherein said measuring device comprises an at least substantially flat assembly of a first sheet-like structural part and a second sheet-like structural part that is attached at least substantially liquid-tightly to said first structural part while enclosing at least one transverse wall that defines said inlet chamber, said recording chamber and said outlet chamber,
• wherein said measuring device (10) is enclosed between a pair of foil sheets that are joined hermetically to each other on a mutual contact surface;
• wherein said collecting device (30) is at least partially formed by and between said foil sheets,
• wherein said receiving member (20) is at least partially formed by and between said foil sheets,
• wherein said receiving device comprises a substantially hollow receiving chamber inside a wall that opens on opposites side, said wall being expandable from a relatively flat storage state to an expanded ready-to-use state in which the receiving member extends between a circumferential upper edge and a circumferential lower edge, a cross section enclosed by said upper edge being significantly larger than a cross section enclosed by said lower edge,
• wherein said receiving member connects at said lower edge to the inlet opening of said measuring device,
• wherein said receiving member carries a form-retaining rim member around said upper edge that is manually deployable from a relatively compact storage state to a deployed ready-to-use state exposing said receiving chamber inside said receiving device, and
• wherein said receiving device is formed by said pair of foil sheets between said rim member and said lower edge.
