Embodiment

[0016] Such as figure 1 The shown medical dialyzer of the present invention comprises: a shell 1, the shell 1 is cylindrical, and a certain number of porous hollow fiber tubes 2 with selectivity are installed in the interior along the axial direction, and a blood inlet 3 is arranged at one end, and a blood inlet 3 is arranged at the other end. Outlet 4, dialysate inlet 5 and dialysate outlet 6 are provided on both sides, blood can be evenly distributed into the shunt device 7 in each hollow fiber tube 2, the patient's blood enters the dialyzer from the blood inlet 3, and the blood enters first The flow diversion device 7 distributes the blood evenly into each hollow fiber tube 2 . At the same time, the dialysate enters the shell side of the dialyzer through the dialysate inlet 5, and adopts the reverse flow method. Due to the pressure difference and concentration difference between the blood side and the dialysate side, the toxins and excess water in the blood are driven by th...

Abstract

The invention relates to a medical dialyzer. The medical dialyzer comprises a casing, flow distributing devices, hollow fiber pipes and a vibration device, wherein the casing is cylindrical; the flow distributing devices are arranged at two ends of the casing; the hollow fiber pipes are arranged between the flow distributing devices and are in airtight connection with the flow distributing devices; the two flow distributing devices are connected with a blood inlet and a blood outlet respectively; a dialysate inlet is formed in the upper part of the casing, a dialysate outlet is formed in the bottom of the casing, and the vibration device is arranged in the middle of the bottom of the casing.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical dialyzer. Background technique [0002] Surveys show that there are more than 100 million kidney disease patients in my country, and most of them need kidney dialysis to alleviate their illness and pain. At present, kidney dialysis in my country is mainly realized through dialyzers. The charcoal kidney widely used clinically has many disadvantages such as not being able to effectively remove excess water in the human body. Although the hollow fiber dialyzer can effectively remove excess water, it has the disadvantages of easy concentration polarization and long dialysis time. . In addition, patients will suffer a lot during the dialysis process, so strengthening the mass transfer process as much as possible, improving the clearance rate, and shortening the dialysis time have become the key issues that need to be solved urgently in the current dialyzer. Contents of the invention ...
