Embodiment Construction

[0026] The detailed description set forth below in connection with the accompanying drawings is intended as a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be practiced. The detailed description includes specific details to provide a thorough understanding of various concepts. It will be apparent, however, to those skilled in the art that these concepts may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form in order to avoid obscuring such concepts.

[0027] Figures 2A-2C is a schematic diagram of a dialysis system according to a first embodiment of the present disclosure.

[0028] Such as Figure 2A As shown in , a dialysis system 200 may include a dialyzer 22, an arterial line 230 with a blood pump 235, a venous line 240 with a venous chamber 244, a venous clamp 246, communicating with the venous cha...

Abstract

A priming method (300, 500, 600) and a priming apparatus (700) are provided. The priming method (300, 500, 600) comprises: controlling, on the condition that an arterial line (230) is blocked and a venous line (240) is opened, a supply device to deliver a priming solution to a dialysate compartment (222) of a dialyzer (220), wherein one end of the arterial line (230) with a blood pump (235) and one end of the venous line (240) with a venous chamber (244) are connected to a blood compartment (224) of the dialyzer (220) and the other end of the arterial line (230) and the other end of the venous line (240) are connected to a container (270, 275) via a connector (280, 285), and the priming solution in the dialysate compartment (222) crosses a membrane of the dialyzer (220) and enters into the venous line (240); turning on, after a predefined amount of priming solution is delivered into the dialysate compartment (222) by the supply device, the blood pump (235) to circulate the priming solution in an extracorporeal circuit composed of the arterial line (230), the blood compartment (224) and the venous line (240). The priming method (300, 500, 600) and the priming apparatus (700) can be applicable in the basic and advanced dialysis machines.

Description

technical field [0001] The invention relates to a preflush method and a preflush device. Background technique [0002] For dialysis treatment preparation, a priming method of flushing and cleaning both the blood tubing set and the dialyzer is required, wherein a normal saline solution is usually used as the priming solution, which is also called dialysate fluid. In order to save labor and cost, an online priming method utilizing dialysate fluid is advocated, but it is mainly available from high-end machines with an online HDF function. [0003] There is a prior art JP2011182992A2 that applies a reverse filtration method on a dialyzer to direct the dialysate fluid across the dialyzer's membrane to the extracorporeal circuit of the dialyzer for priming. Such as Figure 1A As shown in , the arterial line 30 is first pre-flushed, wherein the arterial clamp 90 is opened and the blood pump 50 is operated in counter-rotation when dialysate fluid is delivered through the septum usi...
