the pore diameter of the micro-pore filtration membrane material of the second filter element assembly 7 is between 0.2 and 0.25 microns, and under the condition that bacteria are larger than 0.5 microns, macromolecular substances in plasma of a patient can pass through the pore diameter, so that the passing of the bacteria can be blocked under the condition that the patient is not influenced, and the safety of treatment is improved; for the current non-specific treatment method of the asthma without hepatorenal toxicity, long-term standardized treatment is required to be adhered to control the asthma, so that the recurrence is reduced, the illness state of a patient can be rapidly and effectively controlled, and the quality of life is improved;
through the first decelerating part 304 and the second decelerating part 305 arranged at the inner sides of the blood inlet pipe 301 and the lower guiding pipe 303, when the blood plasma is input to the first filter element assembly 5, the flow velocity of the blood plasma can be buffered twice, so that the direct impact of the blood plasma to the top-mounted filter plate 501 is weakened, IL-8 inflammatory factors in the blood plasma are prevented, the holes of the top-mounted filter plate 501 positioned at the uppermost part are directly blocked, the service life of the top-mounted filter plate 501 is prolonged, and the tops of the rest auxiliary filter plates 502 can fully play a role in the process of adsorbing and filtering the blood plasma;
secondly, by the plasma buffered by the first decelerating section 304 and the second decelerating section 305, after being led into the inner side of the dome cover 9 via the downdraft tube 303, the vertical downward flow speed of the plasma is slowed down, the initial effective contact area between the plasma and the top filter plate 501 is enlarged, and the plasma is exclusively led onto the first filter element assembly 5 mounted above the fixed cover 6 by the dome cover 9, the overall effective contact area between the first filter element assembly 5 and the plasma can be enlarged; through the operation, under the buffer guidance of the plasma by the inlet pipe component 3, the effective filtering area of the plasma by the first filter element component 5 is increased in an auxiliary way, the traditional vertical downward flow guiding type plasma guiding mode is changed, and the traditional direct current pipe type guiding not only ensures that the initial inflow velocity of the plasma is high, but also ensures that the initial effective contact area of the plasma and the filter element is small, thus the filtering effect of the filter element on the plasma is not fully exerted;
meanwhile, by means of the mutual matching between the drainage hopper 11, the collection port 13 and the blood tube 14, the filtered and adsorbed blood plasma can be gathered and guided rapidly and returned to the patient, so that the blood plasma return time is shortened, and the discomfort caused by the filtration of the blood plasma of the patient is reduced;
and utilize the upper port of vault 9 bottom insertion fixed cover 6, eliminate the hidden danger that first filter core subassembly 5 and second filter core subassembly 7 are linked together with external air through gas vent 4, isolate vault 9 promptly, fixed cover 6, drainage fill 11 and the unnecessary space between plasma adsorber 15, utilize the drainage space that plasma adsorber 15, lower casing 2 and dome 9, fixed cover 6, drainage fill 11 constitute jointly, provide dual isolation measure for the appearance of unnecessary bubble in the plasma, guarantee that plasma can fill fast in the drainage space that dome 9, fixed cover 6, drainage fill 11 formed, when avoiding unnecessary bubble to produce, can release the bubble that probably exists from the gap of ring wall under the delivery pressure of plasma, then discharge by gas vent 4, guarantee that this filter equipment filters the smooth of plasma.
The treatment process comprises the following steps: blood is collected and punctured at a vein of a patient by utilizing a blood taking needle, blood of the patient is led out, whole blood of the patient is separated into plasma and blood cells by a plasma separating device, the blood cells are returned into the patient by equipment, the plasma is adsorbed, filtered and purified by an asthma treatment filter, and the purified plasma is returned into the patient:
among them, there are two other treatment regimens that differ in the way plasma is separated by the treatment device:
the second scheme is that the centrifugal plasma single-sampling machine and the peristaltic pump are combined for treatment; wherein, the centrifugal plasma single-sampling machine is used for separating and transporting blood cells from plasma; the peristaltic pump is used for transporting blood plasma and measuring pressure of the filter;
a third scheme is that the column type plasma separator is combined with the continuous blood purifying equipment for treatment; wherein the column plasma separator is used for separating plasma; and the continuous blood purification device is used for transporting whole blood, blood cells, plasma and filter for pressure measurement.
It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art and which are included in the embodiments of the present invention without the inventive step, are intended to be within the scope of the present invention. Structures, devices and methods of operation not specifically described and illustrated herein, unless otherwise indicated and limited, are implemented according to conventional means in the art.
