Hemodialysis concentrated solution preparation device

Abstract

The invention relates to a hemodialysis concentrated solution preparation device comprising a liquid preparation barrel and a barrel cover. A feeding hole, a liquid inlet pipeline and a disinfectant pipeline are arranged on the barrel cover; the tail end, extending into the liquid preparation barrel, of the liquid inlet pipeline is provided with a flow guide pipe; and the flow guide pipe is in close contact with the inner wall of the liquid preparation barrel. An annular pipeline is arranged on the upper end in the liquid preparation barrel along the inner wall of the liquid preparation barrel; a plurality of liquid outlet holes are formed in the annular pipeline; and disinfectant pipeline is connected with the annular pipeline. An air blower is arranged on the other side of the liquid preparation barrel and connected with the liquid preparation barrel through an air path pipeline; a first one-way valve is arranged at the joint of the air blower and the liquid preparation barrel; a second one-way valve is arranged at an air outlet of the air blower; and an air filter element is arranged on the air path pipeline.

Description

technical field [0001] The invention relates to the field of medical devices for preparing medical concentrates, in particular to a hemodialysis concentrate preparation device. Background technique [0002] In recent years, hemodialysis technology has been widely used and developed in the medical field. Dialysis refers to the movement of solutes from a high-concentration solution to a low-concentration direction through a semipermeable membrane, including the movement of solutes and water. The therapeutic range of hemodialysis Wider and wider, the hemodialysis centers of many medical units have become large-scale, and the workload is increasing. At present, the concentrated solution used in the hemodialysis room generally has the following sources: [0003] (1) All the concentrates in barrels are purchased. This method is costly and has certain requirements for storage space, and the required storage space is large; [0004] (2) Purchase all the concentrated powder, and th...

AI Technical Summary

Problems solved by technology

[0003] (1) All the concentrates in barrels are purchased. This method is costly and has certain requirements for storage space, and the required storage space is large;

[0004] (2) Purchase all the concentrated powder, and then centrally supply the liquid through pipelines, but the centralized liquid supply system is expensive, mainly imported products, and some hemodialysis centers also choose to only supply A liquid and self-prepared B liquid, and the prescription is unified, which cannot personalize treatment;

[0005] If you choose to buy all the concentrated powder and make your own concentrated solution or buy concentrated A liquid and B concentrated powder and make your own concentrated B liquid, you need a special preparation tank. The concentrated liquid preparation tank currently on the market has a single function, simple and practical It is not high, and the process of cleaning the preparation barrel is time-consuming and labor-intensive. The amount of disinfectant and purified water is huge, causing waste, polluting the environment, and there are dead corners and blind areas that cannot be disinfected, making it difficult to achieve the cleaning and disinfection effect
