Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a luer connector plug for a dialysate filter. Background Technique

[0002] Hemodialysis treatment and hemofiltration treatment are the main treatment methods for patients in the end stage of uremia and acute and chronic renal failure syndrome. Each hemodialysis machine manufacturer in the market will design a special dialysate filter for its own equipment, and the hemodialysis machine and the dialysate filter of the same brand can be simply, reliably and directly connected.

[0003] Compared with the original imported dialysate filter that is fully adapted to some specific hemodialysis machines in Japan, the dialysate filter produced by Penney has one more passage port. The luer connector at the lower end must be blocked in order to replace the original imported one for use; the protective cover of the luer connector at the lower end of the existing dialysate filter produced by Penney only plays a role in dust prevention and anti-collision protection, and cannot completely play a sealing role. Therefore, the plug of the present utility model is needed to block the luer connector at the lower end of the dialysate filter produced by Penney.

[0004] Therefore, we propose a luer connector plug for a dialysate filter to solve the above problems. Content of the Utility Model
