Definitions

  • the hemodialyzer preferably has a filtration device 71 for filtering blood.
  • the filtration device 71 includes a second housing 73, a blood filtration membrane 61, and a filtrate discharge part 63.
  • This blood filtration membrane 61 is connected to the arterial blood circuit 7 and is a membrane for filtering blood that does not flow into the first housing 3 but flows into the second housing 73.
  • the blood channel layer 43 is a layer provided in the first housing 3 and having the blood channel 41.
  • the blood flow path 41 is a blood flow path for guiding the blood flowing into the first housing 3 to the venous blood circuit 11.
  • the dialysate flow path layer 47 is a layer provided in the first housing 3 and having the dialysate flow path 45.
  • the dialysate flow path 45 is a dialysate flow path for guiding the dialysate flowing into the first housing 3 to the dialysate discharge section 31.
  • the dialysate channel 45 may be connected to the dialysate inlet and the dialysate outlet.
  • the hemodiafiltration membrane 5 is interposed between the blood channel layer 43 and the dialysate channel layer 47 and diafilters the blood flowing through the blood channel 41.
  • FIG. 6 is a conceptual diagram showing a hemodialysis apparatus having a blood channel layer, a dialysate channel layer, and a filtrate channel layer.
  • the blood flow path layer 43, the dialysate flow path layer 47, and the filtrate flow path layer 69 are preferably included in a plurality of layers. In this case, it is preferable that the blood flow path layer 43 and the dialysate flow path layer 47 and the blood flow path layer 43 and the filtrate flow path layer 69 are adjacent to each other.
  • the blood filtration membrane 61 has the same shape (here, hexagonal) as each layer.

  • the blood whose waste product has been scraped by the blood filtration membrane 61 is discharged to the venous blood circuit 11. Further, the filtrate filtered by the blood filtration membrane 61 is discharged to a liquid discharge portion 63 (for example, a tube).
  • the liquid discharge part 63 is connected to a tube connected to the bladder, for example. Then, the filtrate accumulates in the bladder and is appropriately released outside the body.
  • the present invention can be used in the field of medical equipment.

Abstract

Le problème décrit par la présente invention est de fournir un dispositif d'hémodialyse qui réduit le risque d'accidents et d'infections et peut éliminer les déchets à un degré suffisant. A cet effet, l'invention concerne un dispositif d'hémodialyse qui comprend : une membrane de filtration d'hémodialyse 5 à l'intérieur d'un premier boîtier 3; un circuit sanguin côté artériel 7 pour faire circuler du sang dans le premier boîtier 3; un circuit sanguin côté intraveineux 11 pour faire sortir le sang du premier boîtier 3; une unité d'introduction de dialysat 21 qui est raccordée au premier boîtier 3 et introduit un dialysat dans le premier boîtier 3; une unité de décharge de dialysat 31 qui est raccordée au premier boîtier 3 et qui est destinée à décharger le dialysat qui a été à travers le boîtier; et une première unité de raccordement extracorporelle 25 pour raccorder une unité d'alimentation en dialysat d'un dispositif d'alimentation en dialysat extracorporel avec l'unité d'introduction de dialysat 21.
