Method for taking out pipeline packaging liquid

Abstract

The invention relates to a method for taking out liquid packaged in a pipeline. A pipe clamp type liquid taking device is adopted; and the pipe clamp type liquid taking device comprises the following steps that 1), inserting a cylindrical guide pipe for packaging the liquid between a main body and a clamping plate of the pipe clamp type liquid taking device, and fixing the cylindrical guide pipe; 2), using a needle head component, piercing a needle head into a cylindrical guide pipe filled with the liquid, and ensuring that a needle hole of the needle head is completely positioned in the cylindrical guide pipe; and 3) pressing the main body and the clamping plate, and through extrusion of the main body and the clamping plate, extruding out the liquid packaged in the cylindrical guide pipe by using the needle head. According to the method for taking out the liquid packaged in the pipeline, the pipeline for packaging the liquid can be efficiently punctured, the liquid in the pipeline can be accurately extracted, and meanwhile, the safety of an operator can be protected, the operator does not make direct contact with the liquid such as blood or plasma or polluted liquid, efficient extrusion of the liquid in the pipeline is further achieved, the operation success rate is high, and operation is convenient and fast.

Description

technical field [0001] The invention relates to the technical field of liquid-taking tools, in particular to a method for taking out pipe-encapsulated liquid. Background technique [0002] At present, in industries or other fields, a tubular packaging structure is often used for packaging liquids, that is, liquids are packaged in a section of packaging tube. For example, some glues in industry, some reagents used in biochemical experiments, etc., will adopt this packaging method. This packaging method can quantitatively package the required liquid and take the whole tube, which can solve the problem of inconvenient operation in dosage control. [0003] Such packaging also exists in medicine. For example, when donating blood, the blood bank will sample and store the blood of the donor, and the preserved sample will be hot-melted and sealed in a section of blood cylindrical catheter. The above-mentioned reserved blood samples are used for matching with the blood of patients...

AI Technical Summary

Problems solved by technology

[0008] Although the above-mentioned patented technology can solve various problems of manual operation, there are certain defects in its structural design.

Double-sided needles need to pierce both ends of the pipeline, and the two ends of the pipeline are usually hot-melt ends, which are hard and irregular in shape, which can easily lead to failure of needle penetration or bending of the needle during operation, resulting in operation failure

Moreover, after the needle is inserted, there is a certain distance from the inner end of the tube. This part of the liquid cannot enter the needle tube from the tip hole of the needle and cannot be taken out, which will cause a certain amount of liquid waste.
