Description

Medical adsorbent particle sorting device

Technical Field

The utility model relates to a medical adsorbent particle sorting device.

Background

Progressive kidney disease can cause damage to the nephron and its progressive loss of function. When kidney function is not enough to maintain the balance of human metabolism, kidney failure occurs, and serious people turn to uremia and are life-threatening. The annual incidence rate of the end-stage nephrotic patients is 50-150 per million people in the global range, and according to the survey of partial provinces and cities, the annual incidence rate of the end-stage nephrotic patients in China is about 100 per million people.

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. After the last hundred years of efforts, 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, so as to achieve 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.

Wherein, Hemoperfusion (HP) adsorbs middle and large molecule harmful toxicants such as exogenous poisoning substances, creatinine, microglobulin and the like in a patient body through physical adsorption, chemical adsorption, bioaffinity adsorption and the like, and is used in combination with hemodialysis to remove small molecule metabolites such as creatinine, uric acid and the like and also remove middle and large molecule metabolites such as beta 2-microglobulin and the like.

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 adsorption material is easily damaged or cracked due to self or external force in the preparation and transportation processes, and is easily separated from particles, so that the safety and clinical application of the product are affected.

Detailed Description

The present invention will be more fully described with reference to the following examples. The present invention may be embodied in many different forms and should not be construed as limited to the exemplary embodiments set forth herein.

For ease of description, spatially relative terms, such as "upper," "lower," "left," "right," and the like, may be used herein to describe one element or feature's relationship to another element or feature as illustrated in the figures. It will be understood that the spatial terms are intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" other elements or features would then be oriented "above" the other elements or features. Thus, the exemplary term "lower" can encompass both an upper and a lower orientation. The device may be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.

As shown in fig. 1 to 3, the medical adsorbent sorting device in the present embodiment includes a hopper 1 and a rotary sorting table 61; a guide cone 62 is arranged at the center of the rotary particle selecting table 61. The conical surface of the guide cone 62 can provide a guide surface for medical adsorbent particles flowing out of the hopper 1, and the movement direction of the particles falling from the upper part is adjusted from vertical falling to radial movement along the nozzle of the material conveying pipe 2; the particles acquire a greater radial initial velocity.

The bottom of the hopper is provided with a material conveying pipe 2; the medical adsorbent in the hopper 1 is delivered to the rotary sorting table 61 through the delivery pipe 2. A flow control gap is arranged between the outlet of the conveying pipe 2 and the guide cone 62; the flow rate of the medical adsorbent particles can be controlled by adjusting the size of the flow control gap.

The flow control gap can be adjusted by raising the outlet of the feed conveyor pipe 2 or by lowering the height of the guide cone 62. If necessary, an electrically controlled adjusting mechanism may be provided to raise the outlet of the feed conveyor pipe 2 or lower the height of the guide cone 62. The adjustment mechanism may be of the prior art and will not be described in detail here.

To facilitate storage of the medical adsorbent; the medical adsorbent particle sorting device in the embodiment is also provided with a blanking bin 31 for accommodating the medical adsorbent, and the accommodating cavity of the blanking bin 31 is larger than the outer edge of the rotary particle sorting table 61; the particles are caused to fall from the outer edge of the rotating classifier table 61 into the blanking chamber.

In order to collect particles in the particle sorting process, the bottom surface of the blanking bin 31 is provided with a slope surface, the blanking bin 31 is provided with a discharge hole 32, and the discharge hole 32 is arranged at the lower end of the slope surface; thus, the successively screened particles are continuously discharged from the discharge port 32.
