The utility model relates to the technical field of blood preservation, in particular to a stable preservation liquid device for preserving plasma free DNA for a long time, which comprises a preservation liquid device main body, the upper surface of the preservation liquid device main body is fixedly connected with a supporting material receiving shell, and the inner ring surface of the supporting material receiving shell is fixedly connected with a mounting block. And an extended threaded rod is inserted into the surface of the inner ring of the mounting block in a limiting manner. According to the stable preserving fluid equipment for preserving plasma free DNA for a long time, a preserving test tube can be clamped through a fixing plate, the temperature can be adjusted after ice blocks are added into a supporting material collecting shell, and after the temperature is adjusted, a pull handle needs to be pulled, so that the preserving fluid equipment can be used for preserving plasma free DNA stably. And then a user can take down the piston from the supporting material collecting shell, so that ice blocks in the supporting material collecting shell can be replaced, and the preserving fluid equipment can be conveniently transferred to a site through a plurality of universal wheels fixedly connected to the surface of the bottom of the preserving fluid equipment main body and an operation handrail.

The invention discloses a blood preserving fluid suitable for preserving immune cells, which is composed of the following components in terms of 100 ml: 1 to 5 g of glucose, 2 to 4 mg of glutathione, 0.2 to 0.4 g of citric acid, 0.1 to 0.3 g of sodium dihydrogen phosphate, 1 to 3 g of sodium citrate, 8 to 12 mg of sodium ferulate, and 8 to 12 mg of notoginsenoside. The composition comprises L-glutamine, L-arginine, L-aspartic acid, L-histidine, L-glutamine, L-arginine, L-aspartic acid, L-histidine and the like, and the balance of sterile water. By optimizing the formula of the preserving fluid, the stability of the PBMC in the transportation process is specifically maintained, granulocyte activation and pollution are effectively inhibited, immune cell apoptosis is reduced, the multiplication capacity and the cell factor secretion function of the immune cells are maintained, and the recovery rate and activity of the immune cells after long-distance transportation are remarkably improved.

The invention relates to the technical field of blood miRNA preservation, and particularly discloses a disposable blood miRNA preservation tube and a preservation solution thereof, the preservation solution is composed of the following components: 30 mg / ml of glycine, 3 mg / ml of glutamine, 3 mg / ml of glucose, 600 mg / ml of sodium orthovanadate, 3 mg / ml of aluminum fluoride, 25 mg / ml of acetylcysteine, 300 mg / ml of diazoalkyl urea, 2.0 mg / ml of EDTA-2Na, 6 mg / ml of sorbitol, 6 mg / ml of trehalose, and the balance of water. The preservation tube is good in sealing performance and convenient to use, the preservation liquid can effectively slow down rupture of blood cells, DNA in the blood cells is prevented from diluting and polluting target miRNA, nuclease is prevented from degrading the target miRNA, and the preservation period of a blood sample containing target nucleic acid is prolonged.

The utility model relates to the technical field of medical instruments, in particular to a constant-temperature cushioning anti-hemolysis blood storage and transportation device which comprises a transportation box body. The containing cabin is arranged in an inner cavity of the transport case body and slidably connected with an inner cavity of the containing cabin, the containing cabin comprises an anti-coagulation tube storage bin and a constant-temperature bin arranged at the bottom of the anti-coagulation tube storage bin, and a constant-temperature assembly is arranged in the constant-temperature bin; the anticoagulation tube storage device comprises rotating shaft rotating pieces symmetrically arranged on the two side walls of the anticoagulation tube storage bin, a rotating shaft connected with the two rotating shaft rotating pieces, and an anticoagulation tube storage tube arranged on the rotating shaft and connected with the rotating shaft through a universal rotating piece. The cushioning assembly comprises a first cushioning piece arranged on the upper end face of the containing cabin, a second cushioning piece arranged between the lower bottom face of the containing cabin and the bottom of the transport box body and a third cushioning piece wrapping the periphery of the rotating shaft rotating piece.

The invention discloses a multi-union blood bag capable of removing white blood for preserving blood of cats and dogs, which relates to the field of multi-union blood bags for animals and comprises a blood collection bag, a blood taking needle connected with a blood inlet of the blood collection bag, a filtered blood bag connected with a blood outlet of the blood collection bag, and a red blood cell preserving fluid bag connected with the filtered blood bag. The leukocyte filter is arranged between the blood collection bag and the filtered blood bag, the mixing structure is arranged between the blood collection bag and the blood taking needle and can realize mixing of collected blood and an anticoagulant, the anticoagulant bag is connected with the mixing structure, and the one-way control structure is arranged between the anticoagulant bag and the mixing structure; according to the multi-union blood bag capable of removing white blood and used for cat and dog blood preservation, through the mixing structure and the one-way control structure, instant and sufficient mixing of blood and anticoagulant is achieved, and therefore the problems that anticoagulation is delayed and the microclot forming probability is high are solved, and the blood collection quality and preservation safety are improved.
