Cap removal device and thrombelastography device having same
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.
1. A cap removal device comprising a drive part, a connection shaft, and a cap removal member, the cap removal member comprising a first end and a second end, the first end being pivotally coupled to the connection shaft by a first pivot point,
wherein:
(i) the drive part is configured to move the connection shaft upward from a first initial position to an upward position;
(ii) the cap removal device is configured such that, upon upward movement of the connection shaft by the drive part, the cap removal member pivots around a second pivot point located between the first end and the second end, causing the second end to move downward from a second initial position to a downward position so as to contact and remove a cap, and
(iii) the drive part is an electromagnet and the connection shaft comprises a material configured be attracted or repelled by the magnetic force of the electromagnet.
2. The cap removal device of claim 1 , wherein:
(i) the drive part is further configured to move the connection shaft downward from the upward position to the first initial position; and
(ii) the cap removal device is further configured such that, upon downward movement of the connection shaft by the drive part, the cap removal member pivots around the second pivot point, causing the second end to move from the downward position to the second initial position, thereby resetting the cap removal device.
3. The cap removal device of claim 1 , wherein the connection shaft comprises a through hole, the first end passing through the through hole, the through hole being configured to facilitate flexible movement of the cap removal member.
4. The cap removal device of claim 1 , further comprising a control unit, the control unit being configured to, in response to a cap removal request, control the drive part to move the connection shaft upward.
5. The cap removal device of claim 1 , wherein the cap removal member comprises a first part and a second part, the first part being at an angled incline relative to the cap and the second part being substantially parallel to the cap.
6. The cap removal device of claim 1 , the cap removal device is configured for use with a thromboelastography device.
7. A cap removal device comprising a drive part, a connection shaft, and a cap removal member, the cap removal member comprising a first end and a second end, the first end being pivotally coupled to the connection shaft by a first pivot point,
wherein:
(i) the drive part is configured to move the connection shaft upward from a first initial position to an upward position;
(ii) the cap removal device is configured such that, upon upward movement of the connection shaft by the drive part, the cap removal member pivots around a second pivot point located between the first end and the second end, causing the second end to move downward from a second initial position to a downward position so as to contact and remove a cap, and
(iii) the drive part is an electromagnet and the connection shaft comprises a magnet.
