Beneficial effects of the utility model:

The utility model designs a device for the situation that the existing bone marrow fluid is dripped one by one on the glass slide, and the bone marrow fluid is prone to unevenness, and the bone marrow fluid is easy to coagulate when the operation is slow. The liquid dispensing tube constitutes a pipette dropper, and it is detachably installed on the support base. The dispensing tube of the same size and the dispensing hole connected with the joint tube are used to realize the hydraulic pressure of the bone marrow in the syringe. Bone marrow fluid with basically the same quality can be obtained after being put into the pipette dropper. At the same time, a detachable glass slide structure is arranged under the support base to carry the transferred marrow fluid, thus ensuring that it can be carried in multiple carriers at one time. Equal division of bone marrow fluid was achieved on glass slides.
