The invention generally relates to the technical field of medical equipment, in particular to an ECMO pre-filling system and a pre-filling method.The ECMO pre-filling system comprises a pre-filling support, a pre-filling bag and a peristaltic pump, the pre-filling support is sequentially provided with a first connecting part, a second connecting part and a third connecting part from top to bottom, the first connecting part is provided with an infusion bottle, and the second connecting part is provided with a second connecting part; a pre-filling bag is arranged on the second connecting part, a peristaltic pump is arranged on the third connecting part, the infusion bottle is communicated with the pre-filling bag through an infusion pipe, a conveying pipe is connected to the bottom of the pre-filling bag, the conveying pipe conducts infusion pumping on the ECMO pipeline through the peristaltic pump, and a backflow pipe of the ECMO pipeline is communicated with the pre-filling bag. Layered management can be achieved through the pre-filling support, the infusion bottle, the pre-filling bag and the peristaltic pump are sequentially arranged from high to low in the pre-filling liquid flowing direction, and the flowing resistance of the pre-filling liquid and collision mixing between gas and liquid are reduced; meanwhile, the peristaltic pump has a good emptying effect, the ECMO pipeline can be gradually filled with the pre-filling liquid, and gas is prevented from entering the ECMO pipeline again.

The utility model relates to the field of cell sorters, in particular to a sample filling structure of a cell sorter, which comprises a bearing platform, the device further comprises a sealing assembly, a liquid injection assembly, a gas injection assembly, a lifting assembly, a liquid scraping assembly and a braking assembly. A sealing assembly is arranged at the upper end of the bearing table. Liquid is injected into the rotating cylinder through the liquid injection assembly, then the braking assembly is started to drive the rotating cylinder to rotate, and the liquid in the rotating cylinder can be thrown out from the lower end of the rotating cylinder and the liquid outlet groove through the rotation effect of the liquid, can be located on the inner wall of the mixing cylinder and then slides down, so that a small amount of liquid can be quickly mixed, and the mixing efficiency is improved. Then a brake assembly is started to drive a threaded column to rotate, a lifting disc moves downwards along the outer wall of the threaded column, and the side wall of the lifting disc scrapes off liquid attached to the inner wall of a mixing barrel downwards, so that the problems that residual filling liquid in a pipeline is difficult to quickly move out by an existing filling structure, and the filling efficiency is high are solved. And a small amount of different filling liquids are difficult to quickly mix.

The utility model discloses a quick emptying device for diesel oil of an engine, which belongs to the technical field of engines and solves the problem of low efficiency of the existing fuel oil emptying method. The rapid diesel oil emptying device for the engine comprises a cart, an oil drum is arranged on the cart, a pneumatic diaphragm pump is arranged on the cart above the oil drum, an oil return pipe is arranged at an oil outlet of the pneumatic diaphragm pump and communicated with the oil drum, a support is arranged on the cart on one side of the pneumatic diaphragm pump, and the pneumatic diaphragm pump is arranged on the support. The support is detachably provided with an air source triple piece, the air source triple piece comprises an air lubricator, a pressure regulator and an air filter which are communicated in sequence, an air inlet of the air lubricator is provided with a first air inlet branch pipe communicated with the air lubricator, and the other end of the first air inlet branch pipe is provided with a three-way connector; and one interface of the three-way joint is provided with an air inlet header pipe. According to the quick emptying device for the diesel oil of the engine, the working efficiency is effectively improved.
