In order to overcome the above-mentioned shortcoming of prior art, this utility model provides a kind of and on the blood pump of haemodialysis control unit double-layer filtering net is set, utilize double-layer filtering net can filter and remove impurity in the water fully to the water that enters haemodialysis control unit, make the blood after the dialysis cleaner, prolonged the service life of haemodialysis control unit, reduced the obstruction of impurity simultaneously to drainage screen and flow regulator, improved the result of use of haemodialysis control unit, improved the started rate of equipment, utilization rate and efficient, be a kind of simple in structure, easy to assembly and firm haemodialysis control unit with high efficiency filter effect.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of haemodialysis control unit with high efficiency filter effect, comprise a Dialysis container, two doughnuts are arranged in Dialysis container, wherein an end of a doughnut passes through blood pump, pipeline is connected with an injection needle, the other end of this root doughnut passes through blood pump, pipeline is connected with another injection needle, import and export at described blood pump are respectively equipped with drainage screen, this drainage screen comprises internal layer drainage screen and outer filter net, the bottom centre position of outer filter net is provided with through hole, the bottom centre position of internal layer drainage screen is provided with union joint, the other end of union joint is provided with back-off structure, and corresponding with the overanxious online through hole of skin, the surface of internal layer drainage screen and outer filter net all is latticed.
The sidewall of described two doughnuts is close to mutually; Wherein an end of another root doughnut is connected successively by the container of pipeline with heating container, dress dialysis solution, and the other end of this root doughnut is connected with the dialysis solution returnable; Adorning compressed-air actuated bottle for one is communicated with by the internal tank of pipeline with the dress dialysis solution.
Described outer filter net and internal layer drainage screen all are round barrel shape.
The both sides of the through hole that described outer filter sieve bottom center is provided with are provided with brace summer respectively, and thin slice evenly is set between the brace summer at interval.
The back-off structure that is provided with on the described internal layer drainage screen is conical back-off structure, its normal cross-section is a triangle, this leg-of-mutton base is connected with elongate rod, and the length on base is greater than the diameter of the online through hole that is provided with of outer filter, and this triangle and elongate rod are integral structure.
The back-off structure that is provided with on the described internal layer drainage screen is the spheroidal back-off structure, and the diameter of this ball is greater than the diameter of the online through hole that is provided with of outer filter.
The beneficial effects of the utility model are: be respectively equipped with drainage screen in the import and export of blood pump and double-layer filtering net be set on by the water intaking valve at haemodialysis control unit, filter area increases greatly, can the water that enter haemodialysis control unit be filtered fully on the one hand, strengthened filter effect, can make the blood after the dialysis cleaner, reduced pollution and the damage of particulate contamination simultaneously, prolonged the life-span of the use of haemodialysis control unit part in valve body and the haemodialysis control unit; Reduced the obstruction of impurity to drainage screen and flow regulator on the other hand, this filter screen structure is simple in addition, and easy to assembly cutting firmly reduced manufacturing cost simultaneously.When using this utility model, at first dialysis solution is put into about vessel in heating to 37 ℃, then two injection needles is certain intervals and penetrates in the vein, open compressed air again, blood and dialysis solution are dialysed at Dialysis container, thereby can be implemented in the purpose that reaches dialysis blood in the family.
