Description

A hybrid heating device

technical field

The invention relates to the technical field of experimental equipment, in particular to a mixing heating device.

Background technique

Pharmacology is a science that studies the law of interaction between drugs and the body and the mechanism of drug action, mainly including two aspects of pharmacodynamics and pharmacokinetics. The former is to clarify the effect and principle of the drug on the body, and the latter is to clarify the process of drug absorption, distribution, biotransformation and excretion in the body, as well as the law of drug effect and blood drug concentration over time.

The main research method of pharmacology is experiment, and in pharmacology experiment, the mixing of various medicinal liquids is an indispensable process, and it is also an important part of frequent experimental research. If manual stirring is used, the experimental efficiency will be affected. In order to ensure the uniformity of mixing, a stirrer is generally used for stirring, and a heater is used to heat the liquid medicine at the same time.

However, when the existing mixing and heating devices are mixed, two different liquid medicines are directly blended together, and the mixing is realized by stirring the stirring shaft or the like. This mixing method makes it difficult to mix the liquid medicine evenly, and it is also difficult for the stirring components to break up completely, resulting in poor mixing or dissolution of the medicine, thereby affecting the subsequent drug verification results.
