Problems solved by technology

Disadvantages of the closures known from the prior art include that only a relatively small cross-section is released in order for the flow medium to pass through
Another disadvantage: possible sharp burrs at the plastic parts, which can lead to hemolysis when blood flows through
A final disadvantage that must be pointed out is that manual disconnection of the cone causes pain to the operator who often repeats this action

Embodiment Construction

[0048] The view on the left side of FIG. 1 shows a tool 50 that can be actuated manually or by machine and has a collet 54 with a semicircular protrusion 55 and a collet 56 with a similar semicircular protrusion 55 . The recess 57 , the diameter of the recess 57 is larger than the diameter of the protrusion 55 .

[0049] The middle view in FIG. 1 shows a schematic sectional view of a pipeline 10 according to the invention, which is closed by a closing body 20 . The closing body 20 is positioned in the flexible portion 12 of the pipeline 10 . Embodiments are also conceivable in which only the portion 12 on which the closure body 20 is located is made flexible. It is also conceivable that the entire line 10 is made flexible.

[0050] The closing body 20 can be made solid, hollow, open towards the pipeline side or completely closed. It can consist of a porous and non-permeable material or can be made hollow with a filling.

[0051] In order to improve the adhesion between the...

Abstract

The invention relates to a conduit, especially of a blood tube system or blood bag system, comprising a closing element that blocks the conduit passage. Said closing element is formed by a plastically deformable closing member which is disposed in the conduit and blocks the conduit in at least one state. At least the conduit section in which the closing member is located is embodied in a flexible manner.

Description

technical field [0001] The invention relates to a pipeline, especially a pipeline of a blood vessel system or a blood bag system, which has a sealing member blocking the passage of the pipeline. Background technique [0002] For currently known blood vessel systems and blood bag systems it is known to provide an externally openable closure which remains sterile and which is opened by breaking a plastic part. After breaking the so-called fracture cone, the channel for the previously blocked or blocked fluid is released. A blood bag is known from US Pat. No. 6,132,413 with a line closed by such a breakable element. In order to open the line channel, the line with the member is bent, which causes the member to break freeing the line channel. Disadvantages of the closures known from the prior art include the fact that only a relatively small cross-section is freed to allow the flow medium to pass through. In addition, particles are generated due to fracture of the plastic par...
