Blood chamber for extracorporeal blood circuits and a process for manufacturing the blood chamber
First Claim
1. A blood chamber comprising a container body for blood having a plurality of connection ports for fluid communication with outside the container body, each of the plurality of connection ports comprising a tubular mouth configured to be coupled to an end zone of a tube, wherein:
- each tubular mouth is made in a single piece with the container body;
at least one of the tubular mouths is provided with an insert having a surface configured to receive in a fluid-proof sealed coupling the end zone of the tube; and
the insert has at least one first tubular part covering at least a part of an internal surface of the tubular mouth, said at least one first tubular part being configured to be interposed between the internal surface of the tubular mouth and the end zone of the tube, wherein said tubular mouth has an internal surface with at least a first transversal section and at least a second transversal section, the first transversal section being, with reference to the container body. more external than the second transversal section, the more external first transversal section having a larger diameter than a diameter of the internal second transversal section.

Abstract
A blood chamber for extracorporeal blood circuits comprises a container body (2) made in a single piece by blowing of a plastic material, and has a plurality of connection ports (3, 4) for fluid communication with outside; each connection port (3, 4) comprises a tubular mouth (6) having a truncoconical internal surface (61) which is coupled in a fluid-proof coupling to a tubular first part (101) of an insert (10), made by injection molding of a plastic material. The insert (10) has a truncoconical and smooth internal surface (102) which is coupled by gluing with a solvent to an end zone of a fluid transport tube (7, 8). The coupling between the blood chamber and the fluid transport tubes is very strong and reliable. The blood chamber is part of an extracorporeal blood circuit which is operatively associated to a dialysis machine.

22. A blood chamber comprising a container body for blood having a plurality of connection ports for fluid communication with outside the container body, each of the plurality of connection ports comprising a tubular mouth configured to be coupled to an end zone of a tube, wherein:
-
each tubular mouth is made in a single piece with the container body; and at least one of the tubular mouths having an insert having a surface configured to receive the end zone of the tube in a fluid-proof sealed coupling, said insert having at least a first tubular part covering at least a part of an internal surface of the tubular mouth, said at least one first tubular part being configured to be interposed between the internal surface of the tubular mouth and then end zone of the tube, wherein the tubular mouth has an internal surface that converges toward an inside of the container body, said internal surface being joined to an external surface of the insert.
