The invention discloses a fiber reinforced heating device (100) and a mattress equipped with the fiber reinforced heating device (100). The heating device (100) comprises flexible filaments (11) woven vertically and horizontally into a network, hard synthetic resin filaments (12) alternately woven with the flexible filaments (11) in the vertical or horizontal direction, and Copper wire (32) braided with flexible filaments (11) on the longitudinal edges on both sides and center, and the braided material is dipped in liquid carbon and then dried. Connect the copper wires (32) on the two longitudinal edges to the positive (+) terminals (31, 51) and the copper wire in the center to the negative (-) terminal (41). The carbon-coated woven material has a coating (90) formed by compressing or impregnating a gel-type flexible synthetic resin at the top and bottom. The heating device (100) can maintain the original network structure through the hard synthetic resin filaments (12) while maintaining flexibility. The heating device (100) has excellent durability because the flexible filament (11) does not break even when the heating device is subjected to bending or folding. Furthermore, the heating device (100) can provide localized heating by selectively applying power to the positive (+) terminals (31, 51) on both sides.

The invention discloses a soil sampler, comprising a first sampling drill bit, a second sampling drill bit, a first slot, a second slot, a first connecting rod, a second connecting rod, a first handle, a second handle, a first A fastener, a second fastener, a first connecting strip and a second connecting strip; first slots are arranged on both sides of the first sampling drill bit, and the bottom end of the first sampling drill bit is connected to one end of the first connecting rod connected, and the first sampling bit and the first connecting rod are coaxial; the two sides of the second sampling bit are provided with second slots; the bottom end of the second sampling bit is connected to one end of the second connecting rod, and the second sampling The drill bit is coaxial with the second connecting rod. In the present invention, two semicircle-arc sampling drill bits are inserted into the soil successively for sample collection, and the sampling drill bits are easy to press down in the soil; the vertical pressure on the soil sample is small during the pressing down process, and it is easy to keep the original state of the soil; The arc sampling drill bit can be separated directly, which is convenient for taking out the soil sample from the sampling head, and effectively avoids disturbing the soil sample again.

The invention discloses a liquid based cell preservative fluid which is used for matching with an imported or home-made film type liquid based cell film making machine for making films and belongs to the technical field of medicaments. The liquid based cell preservative fluid basically consists of the following components according to the ratios by volume: 10-30 percent of alcohols and the balance of double distilled water; the liquid based cell preservative fluid comprises the following components with the concentration expressed in percentage by mass / volume: 0.1-3.0 percent of phosphate, 0.1-2.0 percent of phenol and 0.1-2.0 percent of N-methyl-N-cyclohexyl-2-amino-3, 5-dibromobenzylamine. Firstly, the invention uses an ordinary biochemical reagent, and the price of consumptive materials is reduced in comparison with the cell preservative fluid produced by an imported auxiliary consumptive material Thinprer TCT. Secondly, because the N-methyl-N-cyclohexyl-2-amino-3, 5-dibromobenzylamine as a unique mucus decomposer is used, the cells wrapped by the mucus in a sample can be successfully separated, avoiding the accumulation and loss of positive cells. Smears prepared by using the liquid based cell preservative fluid to match with an automatic film making machine have clear and transparent backgrounds and uniformly distributed cell monolayers, and are convenient for the film reading of doctors in a pathology department.
