Self-locking T-piece

摘要

A self-locking T-piece connects an attachment to a breathing gas line. The self-locking T-piece has a line section (2), a connection line (4) branching off therefrom, a movable valve body (10) with a valve disk (12), and a valve seat (14). The valve body (10) is prestressed by a spring (16) into a position to seal the connection line (4) against the line section (2), with the valve disk in the valve seat, and moves out of the sealing position when connecting the attachment to the connection line. The valve body (10) is elastically deformable such that it can be advanced through the connection line (4) and the valve seat (14), while undergoing elastic deformation, and returns to its original shape during the entry of valve disk (12) into the line section, in which it has a sufficient extension to be able to cover the valve seat for sealing.

1. A self-locking T-piece for connecting an attachment to a breathing gas line, the self-locking T-piece comprising:
a line section; a connection line branching off from the line section; a spring; a movable valve body with a valve disk body; and a valve seat, wherein the valve body is prestressed by the spring into a sealing position with the valve body engaging the valve seat, in which the valve body seals the connection line relative to the line section, and the valve body is moved out of the sealing position when connecting the attachment to the connection line, the valve body being elastically deformable, such that the valve body can be advanced through the connection line and through the valve seat while undergoing elastic deformation and the valve body returns to an original shape during entry of the valve disk body into the line section, the original shape of the valve body having a sufficient extension to be able to cover the valve seat for sealing.
