Abstract: An apparatus for measuring blood coagulation data, and a use method, a connection member and a support (2101) thereof are disclosed. The apparatus for measuring blood coagulation data comprises: a blood cup support (101), a detachment mechanism (102), and a rotary shaft (103, 805). The blood cup support (101) is used for supporting a blood cup (207) that is not used and a lid (206) of the blood cup, driving, under a first driving force, the blood cup (207) that is not used and the lid (206) of the blood cup to ascend until the lid (206) of the unused blood cup to be connected to the rotary shaft (103, 805), and driving, under a second driving force, a blood cup (207) that is used to descend; and the detachment mechanism (102) is used for separating, under the second driving force, the lid (206) of the used blood cup from the rotary shaft (103, 805). The method can reduce the labor intensity in blood coagulation data measurement.
