Description

Technical Field

[0001] The utility model relates to the technical field of pipettes, in particular to a pipette for blood gene detection experiments. Background Technique

[0002] With the rapid development of genomics and bioinformatics, blood gene detection has become a widely used detection method in the fields of medicine and public health. Through a single cell in a blood sample, a comprehensive analysis of the patient's genetic information can be carried out, so as to help doctors diagnose and treat diseases, predict the prognosis and response of patients, and conduct personalized medicine, etc. When performing detection, pipettes are needed for liquid transfer processing.

[0003] At present, the containers for liquid transfer on the market are mainly traditional pipettes, which have the advantages of high safety such as tips, pipettes, and scales. However, most of the common quantitative pipettes on the market are similar in structure at present. The main body is a glass tube, which is slender and straight throughout. The bottom of the glass tube main body has a small-diameter nozzle of the same material, which is convenient to insert into the solution for suction. There is a rubber head at the top that can shrink and rebound. There are scale marks on the surface of the tube body for measuring the inhalation and removal amounts of the liquid. There are some functional deficiencies in the actual use process and there is room for improvement. For example, the tube body is straight without a buffer section. During the liquid suction process, the rubber head releases too fast, causing a sudden drop in the internal pressure of the tube body. The solution is easily brought into the rubber head, causing corrosion of the rubber head and contamination of the liquid at the same time, affecting the accuracy of the experimental conclusion, and the pipette itself is also damaged. It does not have the function of intermediate buffering to prevent solution contamination, and it is an integrated design, which is not convenient to replace damaged parts and not convenient for cleaning.
