The invention discloses medical dialysis body paper and a production method thereof. The production method of the medical dialysis body paper comprises the following four steps of (1) raw material selection, namely adopting a bleached chemical needlebush pulp board and a hardwood pulp board as raw materials; (2) pulp production, namely breaking and beating the bleached chemical needlebush pulp board and the hardwood pulp board in the step (1) respectively for use; (3) pulp blending, namely mixing pulp in the step (2) in a pulp blending tank according to a ratio, adding a sizing agent and a wetstrength agent, and sending a mixture to a machine chest for use after stirring the mixture; and (4) papermaking, namely conducting papermaking and shaping on the pulp in the step (3) through a pulpconditioning box, a fan pump, a conical scummer and a pressurized screen upper screen part, dehydrating paper through a squeezing part, conducting drying and surface sizing on the paper through a front drying part, drying the paper through a rear drying part, finishing the paper through a soft calendar, treating the paper through a paper winding machine and a rewinder, and the like to produce a qualified finished product.

The invention provides an extraction method for phellinus vaninii polysaccharide. The method comprises the following steps: crushing a phellinus vaninii fruiting body to 1-5 mesh, performing soaking in physiological saline for 8-24 h, performing centrifugation, and collecting residues; boiling the residues of the phellinus vaninii fruiting body in boiling water at 110-130 DEG C for 20-40 min, performing centrifugation, and collecting residues; adding water into the residues, performing freezing for 24-36 h, and performing unfreezing; adding water into the unfrozen mixture to obtain a mixed liquid, adding a complex enzyme into the mixed liquid, performing enzymatic hydrolysis at 50-60 DEG C for 2-4 h, and performing centrifugal separation to obtain a supernatant liquid; and finally, performing adsorption on the supernatant liquid by using resin, performing dialysis, performing concentration, and performing freeze drying to obtain the phellinus vaninii polysaccharide. According to the extraction method for the phellinus vaninii polysaccharide provided by the invention, the extracted phellinus vaninii polysaccharide has obvious activity of inhibiting tumor cell proliferation, has goodbiocompatibility compared with a polysaccharide extracted and purified by a chemical method, and does not bring an inflammatory reaction; and the phellinus vaninii polysaccharide provided by the invention can be used in anti-tumor drugs or health-care products.

The invention relates to a traditional Chinese medicine composition for treating kidney failure and a preparation method thereof. The traditional Chinese medicine composition comprises four Chinese medicines which are barrenwort, milk veteh, rhubarb, and tuckahoe and has the efficacies of warming the kidney, enhancing yang, replenishing qi to invigorate the spleen, fu-dredging and turbidity-purgating, is used for azotemia phase of kidney failure and early stage uremia, can reduce blood urea nitrogen and creatinine, improves and protects renal function, postpones the beginning time of dialysis, reduces number of times of dialysis, improves renal anemia and has the effect of increasing the immune function of human body.

The invention relates to a portable medical rolling pump for testing the performance of a hemodialysis and fluid infusion pipeline. A central control module of the medical rolling pump is respectivelyconnected with a phi 6 peristaltic pump module, a phi 8 peristaltic pump module, a display screen module, a physical button module and a power supply module. Reverse osmosis water or distilled wateris used for simulating human blood, the flow speed, starting and stopping functions of a hemodialysis pipeline are manually set through a solid button, and the pump pipe characteristics of a human body in a dialysis state are simulated. The medical rolling pump is relatively small in size, light in weight, simple in structure, low in manufacturing cost and capable of being conveniently carried tovarious places or various workshops to test the characteristics of pump pipes with different batch numbers.
