Integrated blood treatment module and extracorporeal blood treatment apparatus

Abstract

The invention relates to an integrated blood treatment module (1) comprising a support element and a fluid distribution circuitry associated thereto (15); the distribution circuitry (15) comprises at least a blood line (44), a portion of which is secured to the support element and defines with the latter at least a U-shaped tube length (44a) designed to cooperate, when in use, with a respective pump. There are then further fluid lines (45, 48, 50, 51) fastened to the support element and defining each at least a U-shaped tube length (45a, 48a, 50a, 51a) with respect to said element and each designed to cooperate, when in use, with a respective pump. The support element has a first zone (274) in which the portion of the blood line (44) is secured, and at least a second zone (275) opposite said first zone, to which all the corresponding further tube lengths are fastened.

Description

technical field [0001] The invention relates to an integrated blood treatment module and to an extracorporeal blood treatment device which can receive the integrated module. Background technique [0002] It is well known that in order to perform extracorporeal blood treatment, such as hemodialysis, hemofiltration, haemodiafiltration, plasmapheresis, extracorporeal blood oxygenation, extracorporeal blood filtration or other treatments, at least one extracorporeal access must be provided through which the blood The blood flows and is sent to a processing unit; the processed blood is then returned to the patient's cardiovascular system. With reference to a dialysis treatment by way of example, the extracorporeal access used comprises: a dialysis filter constituted by a housing defining at least first and second chambers separated from each other by a semi-permeable membrane, A blood extraction line leading to a first chamber in the dialysis filter, and a blood return line for ...

AI Technical Summary

Problems solved by technology

[0012] First, it needs to be noted that the specific relative arrangement of the various U-shaped conduit segments, and the corresponding specific relative arrangement of the corresponding pumps supported by the device, does not allow for optimal flow of blood, dialysis fluid, waste fluid, etc. Length of different conduit sections

[0013] Also, it is not possible to use a pump with a larger size in any line without compromising the compactness and overall size of the integrated module (which would thus involve a U-shaped conduit section with a larger size)

[0014] Finally, it should be noted that the current module must be designed for the largest of the four peristaltic pumps used to transport the corresponding fluids, since it is not possible to install other lines than those already provided
