Description
Technical field
This utility model relates to a kind of hemodialyzer housing, belongs to the blood purification technical field.
Background technology
Hemodialyzer cooperates dialysis machine and pipeline, is used for the acute or chronic renal failure patient and carries out hemodialysis.Hemodialyzer is mainly by housing be installed in the intravital macromolecule dialyzer of shell and constitute, when the inlet of blood from housing one end flows in the housing, by the intravital macromolecule dialyzer of shell the time, utilize macromolecule dialyzer both sides solute concentration difference, through infiltration, diffusion and Ultrafiltration, macromolecular substances such as hemocyte in the blood and protein are trapped, and in electrolyte and the water etc., small-molecule substance is separated from blood, liquid outlet through the housing other end is discharged, make in the blood recovery patient body after the purification, reach and remove metabolite and toxicant, correct water, the purpose of electrolyte balance disorder.Present disclosed hemodialyzer housing mainly is made of cylindrical shell and the end cap that is sealedly connected on the cylindrical shell two ends, introduce and discharge dialysis solution by the dialysis solution pipe that is arranged on the cylindrical shell both sides, because dialysis solution is to be introduced into macromolecule dialyzer place from the dialysis solution pipe, and dialysis solution pipe on the cylindrical shell and main cylinder are bypass structures, when so dialysis solution enters cylindrical shell by the dialysis solution pipe, the macromolecule dialyzer that is positioned at dialysis solution pipe one side is contacted with dialysis solution earlier, and contact dialysis solution after being positioned at the macromolecule dialyzer of dialysis solution pipe far-end, so dialysis solution has a time gradient when flowing into from the cylindrical shell end, and can not make dialysis solution evenly flow in the cylindrical shell, can not give full play to the dialysis-effect of macromolecule dialyzer, to blood, the flowability of dialysis solution has certain influence.
Goal of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and is easy to make, can improve the hemodialyzer housing of the dialysis-effect of macromolecule dialyzer.
This utility model is that the technical scheme that achieves the above object is: a kind of hemodialyzer housing, comprise cylindrical shell and two end caps, described cylindrical shell comprises that both sides are provided with the connection cylindrical shell of dialysis solution pipe and diameter less than the main cylinder that connects cylindrical shell, two end cap seal with joint are connected and connect on the cylindrical shell, it is characterized in that: the two ends of described main cylinder extend in the connection cylindrical shell respectively and form annular retaining ring, and annular retaining ring forms the liquid storage chamber with being connected between the cylindrical shell, the end face of annular retaining ring is the inclined-plane, and the height on inclined-plane point is positioned at dialysis solution pipe one side, and the inclined-plane of annular retaining ring and the angle β between the radial section are at 5 °～12 °.
Wherein: the inclined-plane of annular retaining ring (24) and the angle β between the radial section are at 7 °～10 °.
This utility model extends into the two ends of main cylinder respectively in the connection cylindrical shell, make and extend into two annular retaining rings of the intravital shell portion formation of connecting cylinder, make annular retaining ring can form a liquid storage chamber between the cylindrical shell with being connected, therefore when dialysis solution when the dialysis solution pipe flow goes out or flow out, dialysis solution pre-exists this liquid storage intracavity, make at dialysis solution by annular retaining ring and to carry out speed-buffering from the liquid storage intracavity in dialysis solution pipe import department and exit at dialysis solution, make the dialysate flow of each position on the speed that flows into dialysis solution and the entrance section even, the annular retaining ring end face is the inclined-plane in addition, and the height point on this inclined-plane is positioned at dialysis solution pipe one side, therefore make dialysis solution enter cylindrical shell from dialysis solution pipe distal-most end earlier, simultaneously dialysis solution evenly flows to the macromolecule dialyzer around the angled end-face of annular retaining ring, velocity disturbance and velocity gradient that dialysis solution flows into are littler, make the dialysate flow of macromolecule dialyzer position even, blood and dialysis solution exchange are fully, rational in infrastructure, easy to make, can improve macromolecule dialyzer treatment effeciency.
