Embodiment 1

[0039] Such as figure 1As shown, the embodiment of the present invention provides a dialysate regeneration device, which includes the first flow pump 202, the purification unit 230, the liquid storage tank 210, the second flow pump 206 and the dialysis fluid that are connected in sequence through pipelines to form a circulation loop. The outer cavity of device 110. The first flow pump 202 is used to pump the dialysate to be purified from the outer cavity of the dialyzer 110 into the purification unit 230 . The purification unit 230 is used to remove small and medium molecular toxins such as urea, ammonium ions, uric acid, creatinine, phosphate, and β-microglobulin in the blood. Preferably, the purification unit 230 is composed of one or more of activated carbon materials, zirconium-based anion and cation exchange resins, urease, and polymer adsorption materials, which are used to adsorb urea, uric acid, and creatinine in the dialysate. Nitrogen-containing toxoid molecules, o...

Embodiment 2

[0055] This embodiment provides a blood purification system, including a blood circuit and a dialysate circuit, and the dialysate circuit is the dialysate regeneration device in the above embodiment.

[0056] The blood circuit includes a blood pump 101 connected in sequence through the pipeline and the lumen pipeline of the dialyzer 110 in the dialysate circuit. The input end of the blood pump 101 is connected to the human artery through the pipeline, and the lumen outlet of the dialyzer 110 is passed through the tube. The road is connected with the veins and blood vessels of the human body, so that the blood to be purified flowing out of the arteries of the human body passes through the dialyzer 110 for dialysis and purification, and finally re-enters the human body. During the purification process, the external blood is easy to coagulate, so an anticoagulation unit is connected between the output end of the blood pump 101 and the lumen inlet of the dialyzer 110 . The anticoa...

Embodiment 3

[0062] Such as image 3 As shown, the solution in this embodiment has similarities with the above-mentioned embodiments. For the sake of brevity, in the description process of this embodiment, the same technical features as those of the above-mentioned embodiments will not be described. The difference:

[0063] In the blood purification system provided in this embodiment, the fourth liquid pump 205 and the fourth liquid storage bag are removed, and the liquid volume is adjusted through the ultrafiltration unit, wherein the fifth liquid pump 201 in the ultrafiltration unit is a bidirectional pump. During use, if the dialysate in the liquid storage tank 210 exceeds the preset range value, the fifth liquid pump 201 is turned on to store part of the dialysate in the fifth liquid storage bag. If the dialysate in the liquid storage tank 210 If it is lower than the preset range, the fifth liquid pump 201 is turned on in reverse to replenish the dialysate into the liquid storage tank...

Abstract

The invention relates to the field of blood purifying equipment, and discloses a dialyzate regenerating device and a blood purifying system. The dialyzate regenerating device comprises a first flow pump, a purifying unit, a liquid storage pot, a second flow pump and an outer cavity of a dialyzer which communicate with each other through pipelines to form a circulating loop, wherein an ion concentration adjusting unit and an acid-base balance adjusting unit are further arranged on the pipeline between the purifying unit and the liquid storage pot; an electrolyte adjusting unit is further connected on the pipeline between the output end of the liquid storage pot and the inlet of the outer cavity of the dialyzer; and a sensor group used for detecting the ionic concentration, the pH value and the amount of liquid in the liquid storage pot is arranged in the liquid storage pot. For the dialyzate regenerating device and the blood purifying system provided by the invention, the recycling of the dialyzate can be realized, the use amount of dialyzate in the dialysis process is greatly reduced, the dialysis cost is reduced, the integral size of the dialysis device is reduced, the carrying is convenient, and due to the modular design, the system can realize various functions.

Description

technical field [0001] The invention relates to the field of blood purification equipment, in particular to a dialysate regeneration device and a blood purification system. Background technique [0002] When disease or injury causes the decline or loss of human organ function, it will lead to the disturbance of water, electrolyte and pH balance in the body, and various toxins or end products of metabolism in the body may accumulate in the blood or tissues, causing serious damage to the body and endangering life. Blood purification therapy can remove toxins and wastes from the body, control electrolyte and pH balance, and remove excess body fluids from the body. It is an effective therapy for the treatment of organ failure, loss or replacement. [0003] In the traditional blood purification treatment process, the peritoneum or dialyzer is mainly used to diffuse the toxins in the blood in the body to the external dialysate, so that the toxins flow away with the dialysate and e...
