Description

  The present invention relates to an apparatus for producing a hydrogen-containing peritoneal dialysis solution.

  Peritoneal dialysis is one of the effective treatments for patients with renal failure who are unable to excrete urine in order to reduce kidney function and remove water and other harmful substances such as urea. Are known.

  This peritoneal dialysis is a method of removing waste and water present in the capillaries of the patient's peritoneum by injecting dialysate into the patient's abdominal cavity, and has a higher osmotic pressure than body fluid (blood). Peritoneal dialysis fluid is infused, and waste and water are removed from the patient using the difference in osmotic pressure between the body fluid and the peritoneal dialysis fluid via the peritoneum.

  In recent years, it is known that oxidative stress occurs in dialysis patients in peritoneal dialysis. This is considered to be caused by active oxygen generated during dialysis, and it has been proposed to eliminate this active oxygen to reduce oxidative stress.

  For example, a method for producing a dialysis fluid in which a high concentration of hydrogen is dissolved by adding hydrogen molecules to a dialysis fluid sealed in a container has been proposed. More specifically, dialysate is sealed and hydrogen molecules are contacted from the outside of the container (dialysate pack) having hydrogen molecule permeability (the container is immersed in hydrogen-containing water or the container is hydrogenated). A method is disclosed in which hydrogen molecules are contained in the dialysate without opening the container by contacting the gas. And it is described by such a method that the problem of the quality fall of the dialysate resulting from opening of a container can be avoided (for example, refer patent document 1).

  However, in the method for producing a peritoneal dialysis fluid described in Patent Document 1, since the container in which the dialysis fluid is sealed is immersed in hydrogen-containing water, the hydrogen-containing water adheres to the outer surface of the container. As a result, there is a problem that germs and the like propagate on the outer surface of the container in which the dialysate is sealed, and the dialysate is contaminated when performing peritoneal dialysis.

  Further, in the method for producing a peritoneal dialysis solution described in Patent Document 1, a method in which a container in which the dialysis solution is sealed is brought into contact with a hydrogen-containing gas is employed, but there is a risk of ignition even if the amount of hydrogen gas is small. There was a problem that there was.

  Then, this invention is made | formed in view of the above-mentioned problem, and it aims at providing the manufacturing apparatus of the hydrogen containing peritoneal dialysate which does not have the danger resulting from hydrogen gas, and is excellent in the hygiene side.

  In order to achieve the above object, the hydrogen-containing peritoneal dialysate manufacturing apparatus of the present invention has hydrogen permeability, a dialysate bag containing the dialysate, hydrogen permeability, and contains hydrogen. A hydrogen water bag is provided, which contains hydrogen water and supplies hydrogen to the dialysate in contact with the dialysate bag.

  According to this configuration, hydrogen can be supplied to the dialysate by bringing the dialysate bag into contact with the hydrogen water bag, so that the hydrogen-containing peritoneum is superior in terms of hygiene without the dangers caused by hydrogen gas. Dialysate can be produced.

  According to the present invention, it is possible to obtain a hydrogen-containing peritoneal dialysis solution that is superior in hygiene without risk associated with hydrogen gas.

Therefore, it is possible to produce a hydrogen-containing peritoneal dialysis solution that is excellent in hygiene without any risk due to hydrogen gas.

  In addition, in a state where the dialysate bag 4 is in contact with the hydrogen water bag 2, the hydrogen water 5 accommodated in the hydrogen water bag 2 is heated to a predetermined temperature (a temperature in the vicinity of the patient's body temperature, for example, 33 to 35 ° C.). By doing so, the movement of hydrogen to the dialysate 6 is promoted.

  In the present embodiment, since the dialysate bag 4 is stacked on the hydrogen water bag 2, hydrogen lighter than air can be efficiently supplied to the dialysate 6.

  The material which forms the hydrogen water bag 2 is not specifically limited, For example, the material which has hydrogen permeability, such as polyethylene, a polypropylene, a palladium alloy, and a silicon | silicone, can be used.
