[0001] The present invention relates to the technical field of liquid biopsy kits, and in particular to a portable liquid biopsy kit for rapid detection of lung cancer glycosylation markers. Background Art
[0002] With the continuous development of early cancer screening and diagnosis technology, liquid biopsy technology has become a non-invasive tumor detection method and is widely used in cancer marker detection.

[0014] Preferably, a longitudinal section of one end of the limit card block is arranged to be square, and one end of the limit card block is plug-fitted with the limit card slot.
[0015] Working principle: when using the device, the sealing cover is opened to place the test tube inside the receiving groove on the top of the receiving plate, and the test tube is pressed downward so that the bottom of the test tube squeezes one end of the limit card block, thereby squeezing the compression spring to retract the limit card block, so that when the test tube moves downward to a certain position, the compression spring can be used to push one end of the limit card block into the interior of the limit card groove, thereby conveniently fixing the bottom of the test tube, and the pressing rod can be pressed downward to squeeze the squeezing spring, so that one end of the pressing rod moves downward, and then one end of the pressing rod squeezes the connecting block, thereby driving the limit card block to retract, so that the test tube can be pulled upward to conveniently take out the test tube;
[0016] During the downward movement of the test tube, the connecting slider is squeezed to move downward synchronously, thereby driving the connecting ropes on both sides to move inside the connecting groove.

[0017] By starting the cooler and cooperating with the function of the air intake pipe, the external gas is extracted and cooled by the cooler. The dust can be effectively filtered with the function of the filter to prevent dust from entering the machine and affecting the operation. The cooled gas is then transported to the inside of the test kit body through the air outlet pipe, thereby cooling the inside of the test kit body. In this way, the sealing cover and the test kit body are closed, and the inside of the test kit body is sealed by the mutual cooperation of the sealing block and the sealing groove.
[0018] The present invention provides a portable liquid biopsy kit for rapid detection of lung cancer glycosylation markers. It has the following beneficial effects:
[0019] 1. The present invention places the test tube in the accommodating groove and presses the test tube downward, so that the test tube squeezes the limit card block to retract, so that when the test tube continues to move downward, the limit card block cooperates with the rebound effect of the compression spring to enter the interior of the limit card groove, and by pressing the pressing rod downward, one end of the pressing rod squeezes the connecting block to drive the limit card block to retract, so that the test tube can be conveniently taken out, so that the fixing and unlocking operations of the test tube can be more convenient, and the test tube can be conveniently taken out, thereby saving time and improving operation convenience.
[0020] 2. The present invention moves the connecting slider synchronously by moving the test tube downward, thereby driving the connecting ropes on both sides to pull the positioning block to move on the inner wall of the containing plate, so that one end of the positioning block can clamp the outside of the test tube, thereby effectively preventing the test tube from shaking. In this way, while the test tube is fixed, it can also prevent it from shaking during storage, thereby reducing the impact of the external environment on the test tube sample.
[0021] 3. The present invention starts the cooler, draws external gas into the cooler through the air inlet pipe for cooling, and cooperates with the filter to effectively filter dust. The cooled gas is then transported to the inside of the reagent box through the air outlet pipe for cooling. In this way, by transporting the cooled gas to the inside of the reagent box, a stable low-temperature environment is provided during the sample storage process to prevent temperature fluctuations from affecting the sample.
