When the first box 110 and the second box 120 are fastened together, the relatively sealed thermal insulation box 100 is formed. Of course, in practical implementation, the first box 110 and the second box 120 should be made of heat insulating materials. In addition, in this embodiment, the inner walls of the first box 110 and the second box 120 are both provided with insulation cotton. The heat preservation effect can be further improved by the heat preservation cotton. By adopting the openable heat preservation box 100, the dialysate bag can be conveniently placed and fixed.

An outlet pipe notch 111 is formed in the side edge of the first box body 110 adjacent to the hinged edge, and after the dialysate bag is placed into the heat preservation box 100, a dialysis pipe on the dialysate bag passes through the outlet pipe notch 111. Of course, to facilitate the flow of dialysate within the bag, the outlet tube notch 111 should be located on the side near the ground during dialysis.

In this embodiment, in order to facilitate the fixing of the dialysate bag and the flowing of the liquid in the bag, an inner hook 112 is disposed on the inner sidewall of the first box 110 opposite to the outlet pipe notch 111. During dialysis, the dialysate bag is suspended from the inner hanger 112. In addition, an outer hanging rope 113 is arranged on the outer wall of the first box body 110 on the same side with the inner hook 112.

In addition, because the elastic heat-conducting plate 211 and the elastic heat-insulating plate 212 of the heating box 210 have elasticity, under the action of the elastic member 230, the two heating boxes 210 can be tightly attached to the dialysate bag and are always tightly attached to the heating box 210 along with the reduction of the liquid in the bag, so that the heating mechanism 200 can better heat the dialysate bag. The dialysis bag is hung on the inner hook 112 and the whole heater is hung on the infusion support through the outer hanging rope 113, so that the dialysis bag can be fixed conveniently and the liquid in the bag can flow conveniently, and the phenomenon that the dialysate flow is incomplete is avoided.
