Description

Technical Field

[0001] The utility model relates to the technical field of pharmacology, in particular to a convenient pharmacology experiment grabbing device. Background Art

[0002] Pharmacology is a science that studies the interaction between drugs and the body and the mechanism of drug action. It mainly includes two aspects: pharmacodynamics and pharmacokinetics. The former explains the effects and action principles of drugs on the body, while the latter explains the processes of drug absorption, distribution, biotransformation and excretion in the body, as well as the laws of drug effects and blood drug concentrations over time.

[0003] At present, a Chinese utility model with publication number CN212092349U discloses a free grabbing and fixing device for pharmacological experimental objects, including a laboratory table and an operating table arranged on the surface of the laboratory table, wherein a threaded column is screwed into one end of the surface of the laboratory table, a slider is sleeved on the threaded column, a rotating handle is connected to one side of the slider, a gear three is connected to the bottom end of the rotating handle, a gear two is arranged inside the slider, a threaded cap is connected to one end of the gear two, both the gear two and the threaded cap are sleeved on the threaded column, the threaded cap is connected to the slider through a bearing, when conducting a pharmacological test, the experimental object is fixed by the slider and the threaded column, the experimental object will not shake during the experiment, and it is ensured that no error will be generated due to external factors during the experiment, and the height of the experimental object can be adjusted up and down at the same time, which is suitable for all groups of people to operate this product, the product has a simple structure and is easy to operate, and can improve the accuracy of the experiment to a certain extent.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the above equipment, when applied, can solve the problem of using a grasping and fixing device to fix the research object when conducting pharmacological experiments. The original free grasping and fixing devices for pharmacological experiments are mostly handheld. When conducting in vivo experiments, assistants are often required to hold the fixing devices, resulting in excessive waste of manpower. At the same time, when conducting pharmacological experiments, some drugs will carry toxins. When assistants hold the fixing devices, they are likely to come into contact with the drugs, causing damage to the body of the experimenters. At the same time, during pharmacological experiments, the handheld fixing devices will also shake, which is not conducive to the conduct of the experiment and delays the progress of the experiment. However, during use, the gripper cannot replace the clamp, resulting in the clamp being unable to clamp culture dishes or beakers of different sizes, which makes the culture dishes or beakers easy to loosen and tip over. In addition, during the experiment, liquid drugs often splash out of the culture dishes or beakers. When there is a lot of splashed liquid drugs, it is easy to flow out, and the liquid drugs that flow out cannot be collected and need to be manually cleaned by the experimenters, which is easy to cause damage to the hands of the experimenters.
