Abstract:
A blood circuit detaching apparatus for simultaneously detaching a dialyzing artery plastic tube blood circuit and a dialyzing vein plastic tube blood circuit from a dialyzer, comprising:two groove portions for receiving therein the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit, respectively; two dialyzer side clamping portions for clamping a dialyzer-side part of the dialyzing artery plastic tube blood circuit and a dialyzer-side part of the dialyzing vein plastic tube blood circuit, respectively, when the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit are respectively received within said two groove portions; two patient side clamping portions for clamping a patient-side part of the dialyzing artery plastic tube blood circuit and a patient-side part of the dialyzing vein plastic tube blood circuit, respectively, when the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit are respectively received within said two groove portions; two circuit cutting portions for cutting the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit, respectively, between the patient-side part and the dialyzerside part when the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit are respectively received within said two groove portions and clamped by said two dialyzer side clamping portions and said two patient side clamping portions, said two circuit cutting portions being arranged between said two dialyzer side clamping portions and said two patient side clamping portions, respectively; and a cam mechanism constructed and arranged to pivotally move such that said two dialyzer side clamping portions are activated to respectively clamp the dialyzer-side part of the dialyzing artery plastic tube blood circuit and the dialyzer-side part of the dialyzing vein plastic tube blood circuit and said two patient side clamping portions are activated to respectively clamp the patient-side part of the dialyzing artery plastic tube blood circuit and the patient-side part of the dialyzing vein plastic tube blood circuit, and then said two circuit cutting portions are activated to respectively cut the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit between the patient-side part and the dialyzer-side part, whereby the dialyzing artery plastic tube blood circuit and the dialyzing vein plastic tube blood circuit become simultaneously detached from the dialyzer.
