Embodiment 1

[0046] Such as Figure 1 to Figure 3 As shown, a wearable artificial kidney includes a hemodialysis component and a wearable device 10, and the hemodialysis component is installed on the wearable device 10;

[0047] The hemodialysis assembly includes a blood pump 11, a dialyzer, a dialysate pump 15 and a dialysate container 14;

[0048] The blood pump 11 is connected to the dialyzer through a pipeline, and the blood pump 11 is used to provide power for the blood to flow through the dialyzer;

[0049] The dialysate pump 15 is connected in series in the pipeline between the dialysate container 14 and the dialyzer, and the dialysate pump 15 is used to provide power for the dialysate to flow through the dialyzer.

[0050] Specifically, the wearable device 10 above can be a device that can be worn on the human body in the form of a belt, mandarin jacket, backpack, etc., so as to improve the human body wearing the artificial kidney by increasing the contact area between the wearabl...

Embodiment 2

[0053] Such as Figure 1 to Figure 3 As shown, this embodiment is further limited on the basis of Embodiment 1: in the prior art, the dialysate required to complete a single hemodialysis is generally about 150 L, so that when using the artificial kidney, the user does not need to carry A large amount of dialysate to reduce the burden on the dialyser, and also includes a regeneration device 13 for dialysate regeneration,

[0054] A pipeline is also arranged between the dialysate outlet on the dialyzer and the dialysate container 14, and the regeneration device 13 is connected in series in the pipeline between the dialysate outlet on the dialyzer and the dialysate container 14;

[0055] The pipeline between the dialysate outlet on the dialyzer and the dialysate container 14, the pipeline between the dialysate inlet on the dialyzer and the dialysate container 14, the dialysate pump 15, the dialyzer, the regeneration device 13, the dialysate container 14 Together they form a circ...

Embodiment 3

[0060] Such as Figure 1 to Figure 3 As shown, this embodiment further limits this case on the basis of the technical solution provided in Example 2, as a dialyzer solution that requires less dialysate volume to achieve a specific dialysis effect, and the dialyzer includes The dialyzer housing 1, the dialyzer housing 1 is also provided with a blood inlet port 5, a dialysate outlet port 6, a dialysate inlet port 7 and a blood outlet port 8, and the dialyzer housing 1 is also provided with a dialysis tube 3, It also includes a choke part 2 arranged in the dialyzer housing 1, the choke part 2 is located outside the dialysis tube 3, and the choke part 2 is located between the dialysate outlet port 6 and the dialysate inlet port 7, so The choke part 2 is used to increase the resistance of the dialysate flowing through the dialyzer;

[0061] The blood pump 11 is connected to the dialyzer through the blood inlet port 5;

[0062] The blood outlet port 8 is used to connect the pipeli...

Abstract

The invention discloses a wearable artificial kidney. The wearable artificial kidney comprises a hemodialysis assembly, and also comprises a wearable device, and the hemodialysis assembly is installed on the wearable device; the hemodialysis assembly comprises a blood pump, a dialyzer, a dialysis fluid pump and a dialysis fluid container; the blood pump is connected with the dialyzer through a pipe and used for providing power for blood flowing through the dialyzer; the dialysis fluid pump is connected in the pipe between the dialysis fluid container and the dialyzer in series, and the dialysis fluid pump is used for providing power for dialysis fluid flowing through the dialyzer. The wearable artificial kidney can be carried by a dialysis person so that it can be achieved that hemodialysis of a hemodialysis patient is completed in the daily work and life.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wearable artificial kidney. Background technique [0002] Hemodialysis (HD) is one of the renal replacement therapies for patients with acute and chronic renal failure. It drains the blood from the body to the outside of the body through a dialyzer composed of thousands to tens of thousands of hollow fiber tubes. During dialysis, the blood flows through the hollow fiber tubes, and the dialysate flows through the hollow fiber tubes, through diffusion / convection. Carry out solute exchange to remove metabolic waste in the body, maintain electrolyte and acid-base balance; at the same time remove excess water in the body, and return the purified blood to the body. Among them, the hollow fiber tube is a semi-permeable membrane tube covered with tiny holes on the tube wall, and only the solute whose molecular diameter is smaller than the micropores can pass freely. [0003] ...
