[0002] A lancet is a medical device specifically designed for collecting blood samples. It's an indispensable tool in modern medical diagnosis, treatment monitoring, and blood donation. In hospital laboratories, lancets are used to collect blood samples from patients for diagnostic testing and diagnosis of various diseases.

[0003] During the production process of existing blood collection needles, plasticized needle tube materials are extruded into shape using an extruder. Since the temperature of the extruded needle tube is high, it is not convenient to quickly cool the needle tube, and it is easy for the subsequently extruded needle tubes to come into contact with each other, causing the cooled needle tubes to stick together, affecting the molding quality of the needle tube.

[0004] Therefore, in view of the fact that it is inconvenient to quickly cool the needle tubes during the production process of the above-mentioned blood collection needle tubes, and the needle tubes are easily brought into contact with each other, resulting in the cooled needle tubes sticking together, affecting the molding quality of the needle tubes, a rapid extruder for the production of blood collection needles can be designed. By setting up a water-cooling structure, the extruded needle tubes can be dropped into a cooling box for water cooling. The flow of water is used to accelerate the cooling while facilitating the movement of the needle tubes. The cooled needle tubes can be transported and collected to avoid contact with the subsequent extruded needle tubes that have not been completely cooled, thereby preventing the needle tubes from sticking together and affecting the molding quality.
