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). The thrombelastography device has the cap removal device, and thus can achieve the automatic removal of the cap (5) and the automated control on the drive part (1), thereby improving the cap removal efficiency and the test efficiency, and saving time of manually removing the cap.

Core Innovation

The cap removal device comprises a drive part, a connection shaft, and a cap removal member with a first end and a second end. The first end is pivotally coupled to the connection shaft by a first pivot point, and the drive part is configured to move the connection shaft upward from a first initial position to an upward position.

Upon upward movement of the connection shaft, the cap removal member pivots around a second pivot point located between the first end and the second end. This causes the second end to move downward from a second initial position to a downward position so as to contact and remove a cap.

The drive part is an electromagnet, and the connection shaft comprises a material configured to be attracted or repelled by the magnetic force of the electromagnet. In another configuration, the connection shaft comprises a magnet.

Claims Coverage

The document contains two independent claims. Across the independent claims, three inventive features define the mechanical action and magnetic drive linkage.

The claim set centers on converting upward motion of a connection shaft into downward cap-contacting removal via pivoting around an intermediate pivot point, and on electromagnet-based actuation through a magnetically responsive connection shaft.
