[0008] Preferably, corresponding protective pads are provided on the inner walls of the annular grooves.

[0009] Preferably, a granular layer is provided on the top surface of the extension block.

[0010] Preferably, a groove is provided on the front side or right side wall of the housing, an adhesive layer is provided on the notch wall of the groove, and a release paper is provided on the adhesive surface of the adhesive layer.

[0011] Preferably, the shell is made of transparent material.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] Before using this gastrostomy tube fixer, the two extension blocks are pressed by fingers to drive the movable block and the lower clamping wheel to move downward in the shell, so that the gastrostomy tube can be inserted into the shell through the first through hole and extended out of the shell through the second through hole in turn. Then the fingers release the extension block to make the movable block and the lower clamping wheel move upward in the shell, so that the gastrostomy tube can be clamped and fixed by the annular grooves on the upper clamping wheel and the lower clamping wheel, so that the shell is tightly attached to the outside of the patient's abdominal wall through the adhesive layer on the notch wall of the groove. The shell is further bonded and fixed to the patient's abdomen by straps on both sides, so that this gastrostomy tube fixator is more firmly fixed, making it difficult for the gastrostomy tube to move, avoiding long-term inflammation of the skin around the fistula opening and causing discomfort to the patient.
