Since full effluent bags usually weigh around 10 kg, the clinical staff is considerably relieved of this work if the mobile, separately usable bag holder z. B. is placed directly next to the blood treatment device, and the heavy second effluent bag to be emptied no longer has to be laboriously carried around or repositioned.

  • Another advantage of the present invention can also lie in the maximum flexibility with regard to the spatial conditions, for example in treatment rooms or in intensive care units (ICU). Since the second and fourth connectors discussed above (hereinafter referred to as K2 and K4) can always find a fixed place on one of the other connectors or on optional holders, it is advantageously ensured that the effluent drainage line and the pouring line do not hang down and also that when Moving away the bag holder nothing drips.

  • the effluent bag or contents must be emptied into the first effluent bag before the first effluent bag has to be emptied. This can save time and money.
  • the pump section for emptying the second effluent bag with a capacity of 101 (into the first effluent bag) can only require approximately one minute. This is less time than any pending activities on the blood treatment device, for example equipping it with fresh solution bags, require.
  • the height of the pump section relative to the effluent outlet opening of the second effluent bag on the blood treatment device and to the effluent outlet opening of the first effluent bag on or in the bag holder can advantageously be used to enable the venting of a previously air-filled pump section.
  • Another possible advantage is that when the end of the pouring line with the fourth connector, which is opposite the end with the second connector of the pump section, is above the possible filling level of the first effluent bag on the bag holder, the liquid will flow back inside the pouring line when the pump stops can be made possible without liquid running out of the first effluent bag.
  • the flowing back effluent displaces the air usually sucked in towards the end of an emptying process in the pump section, in particular when using an impeller pump, and displaces this air in the direction of the second effluent bag.
  • at least the first connector of the pump section can be arranged preferably less than 27 cm, preferably less than 22 cm, below the effluent outlet opening of the second effluent bag in order to ensure reliable venting. By venting the pump section can be prepared for its next pumping activity.
  • the risk can advantageously be avoided that when the contents of the effluent bag are drained, electrical contact occurs between the effluent and the earth, so that the permissible patient leakage currents would be exceeded, since the bag holder itself does not have to be connected to a power supply.
  • Using a battery-powered pump does not pose a risk of electrical accidents or voltage damage for the patient.
  • Another advantage of the present invention can be that, through its use, workflows at the Blood treatment device can be optimized. Since the emptying of the full first effluent bag has to take place relatively late, depending on its size, the first effluent bag "parked" on the bag holder can, for example, only be pumped empty as soon as the work processes on the patient allow this.
