Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical equipment, and specifically relates to a drug liquid preheating device for drug research and development. Background Art

[0002] The existing liquid medicine preheating usually places the liquid medicine test tube above the heating end, and heats the liquid medicine test tube through the bottom of the heating source to heat the internal liquid medicine. However, the heat conduction is uneven, resulting in uneven heating of the liquid medicine during preheating. Among them, the "a kind of experimental liquid medicine heating system" disclosed with the application number "CN201810774425.6" is also an increasingly mature technology. It can improve the efficiency of the experiment by uniformly and effectively preheating the liquid medicine discharged into the experimental test tube. The liquid medicine is preheated by heat transfer after the liquid is heated. The heat conduction is uniform, and the liquid medicine can be preheated quickly. However, the device also has the following defects: before the heating process, it is not convenient to control the amount of preheated liquid medicine added. At the same time, it is not convenient to recover the evaporated water vapor and liquid medicine during the preheating process after use. After the liquid medicine is preheated, the temperature drops rapidly, which easily leads to a temperature difference in the preheated liquid medicine. Utility Model Content
