Problems solved by technology

However, this is essentially predetermined by the amount present in the bag, making it impossible to adapt to the amount actually required
At the same time, however, a large number of connection steps are necessary, which leads to handling errors and additionally risks contamination of the blood circuit tubing
Also, having multiple different connections on the bag can cause confusion
Transport of the bags and other steps such as sterilization are also complicated as the bags are filled with liquid

Embodiment Construction

[0054] figure 1 with figure 2 A schematic representation of the method according to the invention for priming a blood circuit line and a corresponding first and second embodiment of the blood circuit line according to the invention is shown. Therein, the blood circuit line comprises an arterial line 4 and a venous line 5 , which are connected to the inlets 2 and 3 of the bag 1 on the patient side. Therein, the bag 1 is arranged such that two inlets 2 and 3 are arranged on the underside of the bag, the two inlets 2 and 3 respectively extending into a cavity 40 formed by the bag. Inlets 2 and 3 can be opened or closed via valves 12 and 13 .

[0055] A feeding catheter 9 is connected to the arterial catheter 4 at a feeding catheter point 10, which can be integrated into the arterial catheter or detachably connected to the arterial catheter. The priming fluid can flow via the supply catheter through the T-shaped connection into the arterial catheter 4 .

[0056] The arterial ...

Abstract

The invention relates to a method for priming a blood line set comprising a venous and an arterial line, the connections on the patient side communicating with two separate inlets of a chamber, especially a bag, and the connections on the machine side communicating with a dialyzer. The method according to the invention comprises the following steps: filling in parallel both the venous and the arterial lines via a feed line so that the priming liquid flows into the chamber through both inlets, and circulating the priming liquid in the circuit from the lines, the dialyzer and the chamber via a pump so that one of the inlets of the chamber functions as the inlet and the other as the outlet. The invention also relates to a corresponding blood line set and bag and to a method for producing the same.

Description

technical field [0001] The invention relates to a method for priming blood circuit lines including venous and arterial lines. Background technique [0002] Blood circuit lines of this type are used in extracorporeal blood treatments such as hemodialysis and form an extracorporeal blood circuit during the treatment. Typically, single-use items are used for arterial and venous catheters, which are packaged in a sterile manner and must be primed and flushed prior to treatment. This filling and flushing of the blood circuit—referred to as priming—is used to prevent the blood from coming into contact with air during extracorporeal therapy and to clean the blood circuit and the dialyzer or dialysis filter. For this purpose, the arterial and venous lines are filled with priming fluid, ie with a physiological solution, and the air is thus removed after the arterial and venous lines are connected to the dialyzer on the filter side. After filling, the patient-side ends of the venous...
