Abstract
A biocompatible and/or food-safe tube assembly (1) is used to connect at least three tube connectors (A, B, C). A first tube section (2) serves to connect two (A, B) of the at least three tube connectors (A, B, C). A sec-ond tube section (3) opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2). An orifice sealing body (8) delimits the orifice (4) to the inner lumen of the first tube section (2) and to the inner lumen of the second tube section (3). The first tube sec-tion 2 and the second tube section 3 are molded onto the orifice sealing body 8. A core (10) is used for this purpose. The result is a biocompatible and/or food-safe tube assembly that avoids manufacturing problems.
Claims10
A biocompatible and/or food-safe tube assembly (1) for connecting at least three tube connectors (A, B, C), comprising:
- a first tube section (2) for connecting two (A, B) of the at least three tube connectors (A, B, C);
- a second tube section (3) which opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2);
- and
- an orifice sealing body (8) which delimits the orifice (4) to an inner lumen (6) of the first tube section (2) and to an inner lumen (7) of the second tube section (3),
- wherein the first tube section (2) and the second tube section (3) are molded onto the orifice sealing body (8) and form a single piece that fully encapsulates the orifice sealing body (8),
- wherein the first tube section (2) and the second tube section (3) are made of silicone, and
- wherein the orifice sealing body (8) comprises
- a sleeve section (8a) which extends into the second tube section (3) and
- a further sealing body section (8b) which surrounds the orifice (4) and is designed as a partial peripheral sleeve which extends along a part of a circumference of the first tube section (2).
A biocompatible and/or food-safe tube assembly (1) for connecting at least three tube connectors (A, B, C), comprising:
- a first tube section (2) for connecting two (A, B) of the at least three tube connectors (A, B, C);
- a second tube section (3) which opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2);
- and
- an orifice sealing body (8) which delimits the orifice (4) to an inner lumen (6) of the first tube section (2) and to an inner lumen (7) of the second tube section (3),
- wherein the first tube section (2) and the second tube section (3) are molded onto the orifice sealing body (8) and form a single piece that fully encapsulates the orifice sealing body (8), and
- wherein the orifice sealing body (8) comprises
- a sleeve section (8a) which extends into the second tube section (3) and
- a further sealing body section (8b) which surrounds the orifice (4) and is designed as a partial peripheral sleeve which extends along a part of a circumference of the first tube section (2), and
- wherein the orifice sealing body (8) is made of silicone.
A method for injection molding a biocompatible and/or food-safe tube assembly (1) for connecting at least three tube connectors (A, B, C), including
- a first tube section (2) for connecting two (A, B) of the at least three tube connectors (A, B, C),
- a second tube section (3) which opens into the first tube section (2) via an orifice (4) in a casing wall (5) of the first tube section (2), and
- an orifice sealing body (8) which delimits the orifice (4) to an inner lumen (6) of the first tube section (2) and to an inner lumen (7) of the second tube section (3),
- wherein the first tube section (2) and the second tube section (3) are molded onto the orifice sealing body (8),
- the method comprising:
- providing an injection molding core (10) for defining the inner lumen (6) of the first tube section (2) and the inner lumen (7) of the second tube section (3);
- connecting the orifice sealing body (8) to the core (10) in an area of the orifice (4) of the tube assembly (1) to complete a core to be overmolded;
- inserting the core (10) with the orifice sealing body (8) in an injection mold;
- overmolding the core (10) and the orifice sealing body (8) with silicone and thereby forming the tube sections (2, 3) in the injection mold;
- and
- pulling the core (10).
