[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The present invention is further described in detail below in conjunction with the embodiments.

[0018] like Figure 1-3 As shown in the suction channel, a specific embodiment 1 of a dialysate sealing cover provided by the utility model:

[0019] A dialysate sealing cover comprises a cylindrical side wall 1, a round bottom plate 2 is fixed to the bottom of the cylindrical side wall 1, and a support ring 3 is fixed to the top periphery of the cylindrical side wall 1;

[0020] The circular bottom plate 2 is provided with a central hole 4, a liquid suction channel 5 is fixed at the central hole 4, a rubber positioning plate 6 is provided on the top of the liquid suction channel 5, and at least one connecting hole 7 is provided on the side wall of the liquid suction channel 5;

[0021] The rubber positioning plate 6 is made of rubber material, and is provided with three tearable annular dotted lines 8, and the radii of all the tearable annular dotted lines 8 are different. A plurality of operating heads 9 are provided on the rubber positioning plate 6, and each operating head 9 is located on the upper surface of the rubber positioning plate 6 between two adjacent tearable annular dotted lines 8.

[0022] The dialysate sealing cover of this embodiment is placed on the dialysate concentrate barrel when in use. Figure 2 As shown, the dialysis concentrate barrel comprises a barrel body 10, a barrel mouth 11 is arranged on the top of the barrel body 10, a cylindrical side wall 1 of the dialysis liquid sealing cover is placed in the barrel mouth 11, and the inner diameter of the barrel mouth 11 is equal to the outer diameter of the cylindrical side wall 1, a support ring 3 is supported and placed on the barrel mouth 11, a barrel cover 12 is also threadedly mounted on the barrel mouth 11, a sealing gasket 13 is arranged between the support ring 3 and the barrel cover 12, and the sealing gasket 13 can seal the gap between the support ring 3 and the barrel cover 12 to prevent the concentrate from overflowing from the gap;

[0023] When dialysis is needed, the barrel cover 12 is opened, the sealing gasket 13 is peeled off, and then according to the thickness of the pipette, a suitable tearable annular dotted line 8 is selected, and the operating head 9 is held to tear the rubber positioning plate 6 along the tearable annular dotted line 8, leaving the annular rubber positioning plate 6 on the top of the cylindrical side wall 1. At this time, the outer diameter of the pipette is matched with the inner diameter of the annular rubber positioning plate 6, and the pipette is inserted into the barrel body 10 through the rubber positioning plate 6. The rubber positioning plate 6 is located on the outer periphery of the pipette, thereby adjusting the barrel mouth 11. The connecting hole 7 is sealed to prevent foreign matter from entering. In addition, during dialysis, the connecting hole 7 is used to connect the air pressure in the barrel body 10 with the external atmospheric pressure to ensure the normal suction operation of the pipette. Preferably, the connecting hole 7 is inclined. Specifically, the direction close to the center line of the pipette channel 5 is the inner side, and the direction away from the center line of the pipette channel 5 is the outer side. The inner end of the connecting hole 7 is higher than the outer end. The purpose of such a setting is to prevent foreign matter from entering the interior of the pipette channel 5 through the connecting hole 7, causing contamination of the dialysis concentrate.

[0024] In addition, the liquid suction channel 5, the round bottom plate 2 and the cylindrical side wall 1 together form an annular cavity 14, and the annular cavity 14 can collect liquid spilled at the barrel mouth 11, so as to timely discover the possibility of cross contamination.
