This invention provides a dual-lumen thrombus aspiration catheter assembly, belonging to the field of interventional medical device technology. The assembly includes an aspiration tube body with an aspiration cavity and a guide cavity arranged parallel along the axial direction. The proximal end of the aspiration cavity is used to connect to a negative pressure aspiration device, and the distal end has an aspiration port. A distal protection unit is slidably inserted within the guide cavity. The distal protection unit has a guide portion and an interception portion located distal to the guide portion. The interception portion has a compressed state and an expanded state. During operation, the compressed distal protection unit is transported to the distal end of the target location along with the aspiration tube body. After the interception portion of the distal protection unit detaches from the guide cavity, it expands and supports itself at a set position to intercept any thrombi that fall during the operation. The aspiration cavity of the aspiration tube body can move along the guide portion to adjust the position of the aspiration port. This invention primarily addresses the technical problems in existing technologies where adjusting the position of the aspiration catheter requires repeated establishment of guidewire pathways, and the distal protection requires additional instruments, leading to long operation times and high risks.

This invention relates to the field of semiconductor product testing technology and discloses a high and low temperature testing and conveying device for semiconductor products. The device includes a carrier on which a tray is placed. Several sets of lower pressure plates and upper pressure components are respectively installed on the carrier. The lower pressure plates and upper pressure components are drively connected and move in opposite directions. One set of lower pressure plates has a positive trapezoidal plate, and an inverted trapezoidal plate is also provided inside the testing chamber. The inverted trapezoidal plate cooperates with the positive trapezoidal plate to move the lower pressure plates downwards. By setting relatively movable lower pressure plates and pressure cylinders, the cooperation of the inverted and positive trapezoidal plates during carrier movement drives the automatic clamping of the tray. This forcibly corrects the unevenness of the tray top caused by long-term wear, ensuring that the tray top always remains level. This guarantees that the suction cup can accurately pick up semiconductor products from all positions within a fixed stroke, effectively avoiding missed tests due to partial tray sagging, and significantly improving the integrity and reliability of the test.
