The invention discloses a double-cavity chamber transfusion set, which includes a spike, a soft cannula, a chamber, a transfusion tube and a vena transfusion needle, the vena transfusion needle is connected with the output end of the chamber by the transfusion tube, the chamber includes a chamber
bottle, a dropper arranged in the chamber
bottle and a filter, the dropper is positioned at the middle part of the chamber
bottle and is closely connected with the inner wall of the chamber bottle and partitions the inner cavity of the chamber bottle into an upper cavity and a lower cavity serving as a press cavity, the filter is arranged in the upper cavity of the chamber bottle. Because of the adoption of the technique proposal of the invention, the
peripheral wall of the lower cavity of the chamber bottle can be pinched come-and-go during the blood transfusion process for ensuring that the filter net will not be blocked and the traffic will not be affected, then the pressure in the lower cavity of the chamber bottle can be pushed upward, blood coagulation matters and impurities piled on the filter will be scattered in the upper cavity of the chamber bottle, so the filter is unblocked, thus the dripping amount and blood cleanness of the dropper can be ensured, and the blood coagulation matters and impurities will not flow into the
human body.
