Description

Technical Field

[0001] The utility model belongs to the field of hemodialysis, in particular to a dialysis tube auxiliary positioning device. Background Art

[0002] Hemodialysis, also known as artificial kidney or dialysis, is a type of blood purification technology. It uses the principle of semipermeable membrane to remove harmful and redundant metabolic waste and excess electrolytes from the human body through diffusion, thereby purifying the blood and correcting the water-electrolyte and acid-base balance.

[0003] After searching, a Chinese patent discloses a dialysis tube fixing device for nephrology (authorization announcement number CN213219797U), which includes a first fixed frame and a rotating block, wherein a clamping block is fixed on one side of the first fixed frame, wherein the other side of the first fixed frame is connected to a connecting shaft, and one side of the connecting shaft is connected to a second fixed frame, and a first extrusion groove is provided on one side of the second fixed frame away from the connecting shaft. The dialysis tube fixing device for nephrology is provided with a second rotating block that can be rotated by rotating the positioning block, so that the second rotating block can rotate with the rotating groove when rotating, and the positioning block can drive the positioning groove to coincide with the winding groove while rotating, and the positioning groove and the winding groove are consistent. After the dialysis tube is pulled to be wound inside the winding groove, the positioning block can be rotated after the dialysis tube is wound, and the positioning groove can be rotated to drive the positioning groove to rotate, and the positioning groove can be misaligned with the position of the winding groove when rotating. After the positioning groove and the winding groove are misaligned, the positioning block can squeeze and fix the dialysis tube, which is convenient for the dialysis tube to avoid being scattered when in use.

[0004] In this technology, the dialysis tube is squeezed and fixed by a positioning block, so that the dialysis tube does not become scattered during use. However, positioning the dialysis tube by squeezing can easily cause the dialysis tube to deform, causing discomfort to the patient, and causing the tube diameter at the squeezed location to be different from the tube diameter at other locations, thereby affecting the dialyzer's monitoring of the dialysate delivery volume during dialysis, which can easily lead to medical accidents.
