Abstract
The utility model relates to a medical appliance used for curing acute and chronic renal failure resulted from various diseases. Hollow fiber 2 is arranged in a transparent housing 6 of the dialyzer; the left end of the housing 6 is provided with dialysate outflow openings 1 and 5 and a blood inflow opening 4; the right end of the housing 6 is provided with a dialysate inflow opening 3 and a blood outflow opening 7; the dialysate outflow opening 5 is connected with the dialysate inflow opening 3 by a rubber pipe 10, a flow control pump 9 and a three-way joint 8. The dialyzer can accelerate the speed of flowing of the dialysate, the flow quantity of the dialysate reaches 1000 ML per minute and is twice than the usual blood dialysis quantity, and furthermore, the raw material consumption is not increased, and the removing effect of toxic material is increased.
Description
This utility model relates to the medical apparatus and instruments of the acute or chronic renal failure that a kind of treatment causes because of various diseases, especially a kind of doughnut dialyser that is used for blood purification.
At present, domestic and international clinical employed doughnut dialyser is single current and engages in this profession, and the flowing velocity of dialysis solution is slower, and is not ideal enough to the removing effect of noxious substance.
The purpose of this utility model is to overcome the existing existing defective of doughnut dialyser, provides a kind of flowing velocity of dialysis solution fast, and is effective to the removing of noxious substance, and the double fluid that need not increase the dialysis solution consumption doughnut potentiation dialyser of engaging in this profession.
Task of the present utility model realizes in the following manner: be provided with doughnut in the hyalomitome shell of dialyser, the left end of shell is provided with the blood flow inlet, left end side is provided with the dialysis fluid flow outlet, the right-hand member of shell is provided with the blood flow outlet, the right-hand member side is provided with the dialysis fluid flow inlet, in order to accelerate flowing of dialysis solution, this utility model has additional a dialysis fluid flow outlet at shell left end and former dialysis fluid flow outlet symmetry.
In order to guarantee that the dialysis solution consumption does not increase, a dialysis fluid flow outlet is coupled together by sebific duct, flow control pump and three way cock and dialysis fluid flow inlet, make dialysis solution can be recycled.
This utility model is owing to be provided with two dialysis fluid flow and engage in this profession, thereby accelerated the flowing velocity of dialysis solution greatly, and the dialysate flow of per minute reaches 1000ml, is 2 times of hemodialysis amount usually; Because this dialyser is provided with the dialysis solution EGR, so the dialysis solution total amount that is consumed is constant, does not promptly increase consumption of raw materials, can improve the removing effect to noxious substance effectively.The applicant has carried out hemodialysis with this dialyser 25 times to 4 routine chronic renal failure patients, and process is smooth, has no adverse reaction.Through dialysis in 5 hours, Bun can descend 50～65%, and SG descends 30～40%, and hemodialysis improves usefulness 20% usually.Patient feels well, the very fast disappearance of skin itching, and hematochrome rises very fast, and the blood transfusion requirement reduces.
Concrete structure of the present utility model is provided by drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples this utility model is described in more detail.
Embodiment:
With reference to Fig. 1, thousands of doughnuts 2 are housed in the hyalomitome shell 6, the left end of shell 6 is a blood flow inlet 4, the left end top is provided with dialysis fluid flow outlet 1, the left end below is provided with dialysis fluid flow outlet 5, the right-hand member of shell 6 is blood flow outlet 7, and the right-hand member top is provided with dialysis fluid flow inlet 3, and dialysis fluid flow outlet 5 is connected with dialysis fluid flow inlet 3 by sebific duct 10, flow control pump 9 and three way cock 8.
