The invention discloses a high-breathability water absorbable acrylic ester foamed material as well as a preparation method and an application thereof. The prepared high-breathability water absorbable acrylic ester foamed material has strong toughness, and good breathability; the obtained foamed material is small in cell size, average deionized water absorption rate, average saline water absorption rate, average artificial urine absorption rate and average artificial blood absorption rate of the obtained foamed material are respectively higher than 15g / g, and water retention rate in half hour is more than 80%, so that the high-breathability water absorbable acrylic ester foamed material is applicable to dispersion and storage of water containing fluid; meanwhile, nano calcium carbonate is added, so that production cost is obviously reduced, and the high-breathability water absorbable acrylic ester foamed material is applicable to mass production; a block flexible water absorbing material in the invention is suitable for application in the field of health products.

The invention discloses a 11-dehydro-thromboxane B2 determination kit. The kit comprises: a reagent R1 including 0.01-2% (w / v) of 11dhTxB2 antibody and a buffering solution; a reagent R2 including 0.1-2% (w / v) of a 11dhTxB2 protein coated latex nanoparticle buffering solution; a calibrating substance comprising the 11dhTxB2 protein and a buffering solution; and a quality control substance which is a 11dhTxB2 protein dissolved in artificial urine. The 11-dehydro-thromboxane B2 determination kit improves the sensitivity and the linear range of detection of the 11-dehydro-thromboxane B2 content of urine, the detection sensitivity can reach 775pg / ml, and the linear range can reach 0-6300pg / ml. The 11-dehydro-thromboxane B2 determination kit has the advantages of high sensitivity, good specificity, high accuracy, good precision and good stability.

The invention belongs to the field of biological macromolecular probes, and particularly relates to a fluorescent reagent and a method for measuring human albumin and efficiently and quickly identifying the human albumin and bovine serum albumin. A schiff base organic compound with a typical torsion intramolecular charge transfer feature is designed and synthesized on the basis of a triphenylamine and 15-crown-5 ester structure, and is used as the fluorescent reagent; protein is added into a neutral phosphate buffer solution, the human albumin can be quickly identified from several types of common proteins according to compound fluorescent spectrum features, and a standard curve is established to quantitatively measure the contents of serum proteins in a buffered saline solution and artificial urine. The concentration of the probe reagent is 50mu M, and the 5mu M human albumin can be identified; after quantitative detection, the range of the human albumin in the buffered saline solution is 0 to 5.6mu M, and the minimum detection limit is 0.112mg / L; the range of the human albumin in the artificial urine is 0 to 1.2mu M, and the minimum detection limit is 1.95mg / L.

The invention relates to an intelligent urine detector, a urinal and a urine detection method. The intelligent urine detector comprises: a feeding mechanism comprising a storage box and a pushing unit, wherein the storage box is filled with a plurality of test paper boxes, and the pushing unit is used for pushing the test boxes to a two-dimensional conveying mechanism; the two-dimensional conveying mechanism which is controlled to move along a first direction to realize feeding or discharging or is controlled to move along a second direction to realize urine taking or supplied urine information reading; a scanning mechanism used for reading the urine information in the test paper boxes; and a control mechanism connected with the feeding mechanism, the conveying mechanism and the scanning mechanism to control coordinative work of all the mechanisms in order to realize intelligent urine detection. The intelligent urine detector, the urinal and the urine detection method effectively overcome the disadvantages of artificial urine detection, and realize feeding, automatic urine taking, urine information reading and discharging through adopting the cooperation of the feeding mechanism, the two-dimensional conveying mechanism, the scanning mechanism and the control mechanism.
