Background
The annual incidence of this end-stage renal disease is 50 ~ 150/million worldwide, and according to some provincial surveys, the end-stage incidence of our country is about 100/million.
In order to remedy these patients at risk of dying, dialysis was proposed in the middle of the 19 th century to eliminate the possibility of toxic symptoms in patients with renal failure by removing diffusible substances from their blood. Through the recent hundred years of effort, the Dutch Kolff first applied the regenerated cellulose dialyzer to clinic in 1943, and initiated a new era of replacing kidney function with artificial devices. In fact, the basic technical concept of artificial kidney is to draw the blood of a patient out of the body, to complete the transfer and removal of solutes and water in the blood by using devices (such as hemodialyzer, hemofilter, etc.) made by different technical principles, and then to return the purified blood to the human body to achieve the purpose of treatment; namely, the transfer and removal of metabolic waste, poison, pathogenic factors, water and electrolyte which are to be removed in blood are completed through the biophysical mechanism of the artificial kidney, thereby achieving the balance of internal environment. In recent years, basic research on artificial kidneys has been greatly advanced due to interpenetration of various disciplines, development of new devices has been advanced, and new technologies have emerged.
The Hemoperfusion (HP) adsorbs middle and large molecule harmful toxicants such as exogenous toxic substances, creatinine and microglobulin in a patient body in a physical adsorption mode, a chemical adsorption mode, a biological affinity adsorption mode and the like, and is used in combination with hemodialysis, so that small molecule metabolites such as creatinine and uric acid can be removed, and middle and large molecule metabolites such as beta 2-microglobulin can also be removed.
The core of the disposable blood perfusion device technology is the use of the adsorption material filled in the tank body, and the adsorption material not only is safe and nontoxic for human bodies, does not cause anaphylactic reaction and pyrogen, but also has stable chemical property, regular appearance, no breakage, no falling of particles, good blood compatibility and the like. Therefore, no matter the adsorbent is an activated carbon material or a macroporous resin material, on the premise of ensuring stable chemical properties, good biocompatibility becomes a key point that the material can be successfully applied to clinic. The appearance of the adsorbing material is spherical particles, and the surface is smooth. However, the adsorbing material is easily damaged or cracked due to self or external force during the preparation and transportation processes, thereby damaging blood visible components such as erythrocytes and the like and causing poor biocompatibility. Meanwhile, particles are easy to fall off after the particles are damaged or cracked, and the fallen particles enter a human body system through extracorporeal blood circulation, so that the safety and clinical application of the product are seriously influenced.
