[0021] The utility model will be further explained in detail as follows:

[0022] For example Figures 1 to 5The utility model provides a CRRT pipeline fixer, including connecting portion 1, the top fixed connection of connecting portion 1 has base 2, the top fixed connection of base 2 has fixed assembly 3, and fixed assembly 3 includes the connecting plate 31, and the top fixed connection of connecting plate 31 has inner fixed sheet 32 and outer fixed sheet 33, and inner fixed sheet 32 is located the inside setting of outer fixed sheet 33, and the inside setting of inner fixed sheet 32 has inner click 34, and the outside setting of outer fixed sheet 33 has the adjusting tooth 35 of adaptation with inner click 34.

[0023] Through setting the inner fixed sheet 32 cooperation outer fixed sheet 33 that is symmetrically arranged above the connecting plate 31, it is made into the elastic material and can be moved deformation, through the adjusting tooth 35 of outer fixed sheet 33 outside setting is clamped in the inside setting of inner click 34 in the inside setting of inner fixed sheet 32, and the limit is carried out, to facilitate the double pipeline separation of CRRT pipeline and is fixed, through the inner fixed sheet 32 and outer fixed sheet 33 through the inner click 34 and adjusting tooth 35 cooperation adjustment avoids the pipeline to come out when fixing CRRT pipeline, is more practical, through the contact layer 11 adopts non-woven fabric material, cooperation left and right setting glue layer 12 in its bottom is pasted on the skin of patient, to ensure good air permeability, reduce the discomfort of long-time pasting.

[0024] As Figure 3 The inner fixed sheet 32 and outer fixed sheet 33 are symmetrically arranged on the top of the connecting plate 31.

[0025] The inner fixed sheet 32 and outer fixed sheet 33 are symmetrically arranged on the top of the connecting plate 31.

[0026] As Figure 3 And Figure 4 The inner fixed sheet 32 and outer fixed sheet 33 are symmetrically arranged on the top of the connecting plate 31.
