Liquid preparation and transfer mechanism

Abstract

The invention discloses a liquid preparation and transfer mechanism. The liquid preparation and transfer mechanism comprises a liquid preparation mechanism and a transfer mechanism, wherein the liquidpreparation mechanism comprises columns, a large cross beam is installed on the columns, small cross beams are movably installed on the large cross beam in the X direction, and a liquid dropping assembly is movably installed on the small cross beams in the Y direction. The liquid preparation action is automatically completed through the liquid preparation mechanism so that titrated liquid drops can be regular in position, size and shape; meanwhile, the amount of liquid titrated can be accurately controlled, and the oil covering amount of the liquid can be accurately controlled; in addition, after the liquid preparation action is completed, the titrated liquid can be immediately put into an incubator by the transfer mechanism to be subjected to pretreatment of temperature and PH value adjustment; and finally, the whole liquid preparation process does not need manual intervention, so that the labor cost is greatly reduced. The liquid preparation and transfer mechanism is suitable for preparation and pretreatment of a culture dish before embryo culture.

Description

technical field [0001] The invention relates to the technical field of embryo culture, in particular to a liquid preparation transfer mechanism. Background technique [0002] At present, in the field of assisted reproduction, during the embryo culture process, it is necessary to prepare a culture dish for embryo culture in advance. This process is called liquid preparation. Then squeeze the A burette to titrate the culture liquid in the petri dish according to a certain arrangement, the titrated quantity is measured by the number of squeezes, the titrated position is controlled manually, and the titrated size is manually observed by the operator. Control; then squeeze the B buret to titrate a certain amount of mineral oil liquid, so that the mineral oil can completely cover the droplet of the culture solution, prevent the water in the culture solution from volatilizing, and affect the change of the osmotic pressure of the culture solution; after dripping, manually Then put ...

AI Technical Summary

Problems solved by technology

[0003] 1. The droplet shape and position of the artificially titrated culture solution are irregular, and the titration is not easy to control accurately;

[0004] 2. The amount of mineral oil manually titrated is not easy to accurately control;

[0006] 4. The process of preparing petri dishes usually requires manual long-term operation, which is a waste of manpower
