Problems solved by technology

[0006] 1. It needs to consume a lot of ultrapure water, and a treatment needs 200-300L ultrapure water
[0007] 2. Simultaneous use of multiple life support systems requires a large space, and the operation of each life support system is relatively complicated, which is not conducive to normal treatment, especially in outdoors, disaster sites and other remote areas where medical conditions are lacking. Allows simultaneous use of multiple life support systems

Embodiment 1

[0044] figure 1 It is a schematic diagram of a blood extracorporeal circulation life support system provided in Example 1 of the present invention. refer to figure 1 , the system consists of:

[0045] A blood circulation subsystem 20 and a dialysis circulation subsystem 30 . The blood of the living body enters the blood circulation subsystem 20 through the circulation pipeline for circulation.

[0046] It can be understood that the circulation pipeline includes three parts, the circulation pipeline connecting the living body and the blood circulation subsystem 20, the circulation pipeline connecting the various components of the blood circulation subsystem 20, and the circulation pipeline connecting the various components of the dialysis circulation subsystem 30 . In addition to the circulation pipeline, the blood extracorporeal circulation life support system also includes other devices distributed in the blood circulation subsystem 20 and the dialysis circulation subsyst...

Embodiment 2

[0070] figure 2 It is a structural diagram of a dialysis circulation subsystem 30 provided by Embodiment 2 of the present invention. figure 2 exist figure 1 On the basis of , the configuration of the ion adjustment device 32 and the temperature adjustment device 35 in the dialysis circulation subsystem 30 is refined. refer to figure 2 , according to the order of dialysate flow, the ion regulating device 32 includes a first solution adding port 321 , an ion sensor 322 , a second pump body 323 and a second solution adding port 324 . The temperature regulating device includes a temperature sensor 351 and a constant temperature device 352 .

[0071] Specifically, the dialysate enters the water balance device 33 after being exchanged with the blood in the hemodialysis device 23 . The water balance device 33 can accurately control the amount of ultrafiltration through weight or flow feedback, and remove part of the dialysate, thereby indirectly removing part of the water in th...

Embodiment 3

[0108] Figure 9 A structural diagram of a blood circulation subsystem provided by Embodiment 3 of the present invention. Embodiment 3 is refined on the basis of Embodiment 2, and provides two other structures of the blood circulation subsystem, both of which can achieve the purpose of increasing blood flow.

[0109] refer to Figure 9 , the blood circulation subsystem 20 further includes a blood pump circuit, and the blood pump circuit includes a first blood pump 25 and a second blood pump 26 connected in parallel. The first blood pump 25 is arranged in front of the first toxin removal device 21, so that blood flows out from the blood outlet and flows into the first toxin removal device 21 through the first blood pump 25; The second blood pump 26 allows the blood to flow into the oxygenation device 22 through the second blood pump 26 after flowing out from the blood outlet. That is, the blood enters the blood circulation subsystem 20 through the blood outlet, and at this t...

Abstract

The invention relates to a blood extracorporeal circulation life support system. The system comprises a blood circulation subsystem and a dialysis circulation subsystem; blood of the living body enters the blood circulation subsystem through a blood outlet of the living body via a circulation pipeline to be circulated and then flows back to the living body through a blood inlet of the living bodyvia the circulation pipeline; the blood sequentially passes through a first blood pump, a first toxin removing device, a hemodialysis device, a feeding device and an oxygenation device in the blood circulation subsystem; and the dialysis circulation subsystem exchanges substances with the blood circulation subsystem through the hemodialysis device, and dialysate in the dialysis circulation subsystem flows back to the hemodialysis device through a water balance device, a first pump body, a second toxin removing device, an ion adjusting device and a temperature adjusting device in sequence afterflowing out of the hemodialysis device. By means of the system, dialysate regeneration and blood purification are conducted at the same time, and the size and operation difficulty of the blood extracorporeal circulation life support system are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood extracorporeal circulation life support system. Background technique [0002] When the organs of the body fail or are damaged, it will cause the accumulation of toxins or metabolites in the body. These accumulations will lead to electrolyte and pH imbalances, increased body fluids, and low oxygen saturation in the body, which will seriously endanger the health of the body. At the same time, organ failure is prone to complications, leading to multiple organ failure or damage. [0003] In order to achieve the purpose of treating the failure or damage of organs, it is necessary to extract the blood of the organism from the body for purification, to remove toxins and wastes in the blood through continuous extracorporeal circulation, to control the balance of electrolytes and pH in the blood, to remove Remove excess fluid from the blood. [0004] In the process of dr...
