  • Patent number: 11927587
    Abstract: A thrombelastography device, a heating apparatus, a blood coagulation analysis system, and a rotational angle measurement method are disclosed. The thrombelastography device consists of a plurality of thrombelastography device splits (2) that are horizontally arranged in parallel. The thrombelastography device split (2) comprises a worktable (4), a rack (5), a test bar (6), a tester (8), and a processor (9). The thrombelastography device overcomes the defect in the prior art that the measurement result of a thrombelastography device is inaccurate. The amount of reflected light is used as a reference for thrombelastographic evaluation, and thus the result is more accurate.

  • Patent number: 11866311
    Abstract: A cap removal device and a thrombelastography device having same are disclosed. The cap removal device comprises a drive part (1), a connection shaft (2), and a cap removal member (3). The connection shaft (2) can move upward when driven by the drive part (1). The cap removal member (3) has an end (31) and the other end (32); the end (31) is pivotally connected to the connection shaft (2), so that when the connection shaft (2) moves upward when driven by the drive part (1), the cap removal member (3) rotates, due to the upward movement, around a pivot point (4) located between the end (31) and the other end (32) of the cap removal member (3), so that the other end (32) of the cap removal member (3) moves downward to contact a cap (5) to be removed, thereby removing the cap (5).
