Description

TECHNICAL FIELD

[0001] The utility model relates to pipette technical field especially relates to a grommet bromide neostigmine injection liquid pipette. BACKGROUND

[0002] Pipette is a precise liquid handling tool commonly used in laboratories, which is mainly used for accurate and rapid transfer and distribution of micro-liquid in scientific research fields such as biology, chemistry, medicine, etc. The design principle of pipette is usually based on air displacement or piston principle, and the piston is driven by manual or electric mode to generate negative pressure in the gun head, so as to suck or release liquid.

[0003] When using pipette to manually suck injection liquid, it is difficult to ensure that the depth of needle insertion is consistent every time because the pipette is inserted into the container by hand operation. If the depth of needle insertion into the injection liquid is different every time, a series of problems may be caused, such as different compression degree of air in the gun head and change of residual liquid volume, etc. These problems will directly affect the accuracy of pipette during each pipetting, thus causing errors. For injection liquids such as grommet bromide and neostigmine, accurate dosage is crucial because their effects in experiments or treatment are closely related to dosage. If there is error in pipette during pipetting, it may lead to inaccurate dosage of these injection liquids, thus affecting the reliability of experimental results or the effectiveness of treatment.
