Problems solved by technology
[0003] In the process of using a medical centrifuge, because it separates blood samples, it does not need to be completely crushed, and high-speed separation will cause excessive separation of blood samples. In addition, in order to ensure the effect of fast centrifugation, it is usually necessary to use an air pump for negative pressure treatment , and the noise of the air pump will have a great impact on the hospital environment

The invention provides a low-speed self-pumping negative pressure centrifugal machine for a medical laboratory, and relates to the technical field of centrifugal machines. The upper end of the supporting base is in butt joint with a bearing ring. A shunting cover is mounted on the supporting base below the bearing ring; a centrifugal barrel is mounted on the bearing ring; a control box is mounted at the upper end of the centrifugal barrel; and the upper end of the driving rod is correspondingly and rotationally sleeved with a centrifugal rod. When a driving rod rotates, on one hand, a balancing frame drives a centrifugal rod to rotate centrifugally, on the other hand, a driving gear drives a planetary gear to rotate, an air draft wheel can rotate, and therefore negative pressure extraction can be conducted on an inner cavity of a centrifugal barrel, centrifugal operation can be better guaranteed, and huge noise brought by an air pump is removed; the problems that blood samples are excessively separated due to high-speed separation, and the hospital environment is greatly affected by noise of an air compression pump are solved.
Description
technical field [0001] The invention relates to the technical field of centrifuges, in particular to low-speed self-pumping negative pressure centrifuges used in medical laboratories. Background technique [0002] Medical laboratory centrifuges are mainly used in medical experiments, hospitals, pharmaceutical companies, biological research institutes, and fine chemicals. Centrifuges are used; when testing pharmaceutical ingredients, centrifuges are often used for component separation. [0003] In the process of using a medical centrifuge, because it separates blood samples, it does not need to be completely crushed, and high-speed separation will cause excessive separation of blood samples. In addition, in order to ensure the effect of fast centrifugation, it is usually necessary to use an air pump for negative pressure treatment , and the noise of the air pump will have a great impact on the hospital environment. Contents of the invention [0004] In view of this, the p...
