Apparatus For Cup Loading and Unloading and Thromboelastography Machine

A thromboelastography machine, comprising an apparatus for cup loading and unloading, wherein the apparatus comprises:

• a base;
• a shaft, rotatably connected to the base about an axis of the shaft and having an end configured to engage with an inner cup;
• a movable cover, disposed around the shaft and slidably connected to the base along the axis of the shaft, the movable cover being provided with an elastic member therein;
• a cup holder, slidably connected to the base along the axis of the shaft and disposed below the base and the shaft, the cup holder having a cavity configured to engage with an outer cup, and the cavity having an open directed upward;
• a cup ejection assembly, comprising an ejection driving mechanism and an ejection block, the ejection block being slidably connected to the shaft along the axis of the shaft, the ejection driving mechanism being disposed between the base and the ejection block and configured to provide a downward force on the ejection block, and the elastic member being disposed between the ejection block and the movable cover and configured to provide an upward force on the ejection block when in a deformation state;
• and
• wherein, when the cup holder slides upward to a contact position, the cup holder is in contact with a bottom end of the movable cover, and an upward movement of the cup holder drives the movable cover to slide upward;
• the elastic member is configured to provide a downward force on the movable cover when in a deformation state;
• and
• an approach movement between the end of the shaft and the cup holder is configured to generate a force to engage the inner cup with the end of the shaft and to engage the outer cup within the cavity of the cup holder.
