Technical Field
[0001] This utility model relates to the field of traditional Chinese medicine testing technology, and in particular to a sample preparation device for traditional Chinese medicine testing. Background Technology
[0002] The preparation of test samples for traditional Chinese medicine (TCM) analysis is one of the key steps in TCM analysis and testing. For solid TCM materials, such as roots, rhizomes, and fruits, grinding or pulverizing is required to obtain fine powder samples suitable for analysis. The processed TCM materials are placed in a test sample preparation device. According to the component characteristics of the TCM materials and the testing requirements, a suitable solvent is selected for extraction. Commonly used solvents include ethanol. The effective components of the TCM are dissolved into the TCM mixture by heating and stirring. Finally, the TCM test sample is obtained by filtration.
[0003] Previous sample preparation devices for traditional Chinese medicine (TCM) testing had the following drawbacks: 1. They were inconvenient for accurately measuring the added ethanol solvent, 2. They were inconvenient for filtering the medicinal solution for convenient use in TCM testing, and 3. They were inconvenient for cleaning up residual residue. Therefore, those skilled in the art have provided a sample preparation device for TCM testing to solve the problems mentioned in the background art. Utility Model Content

[0012] As a further embodiment of this utility model: a screwing block is fixedly fitted on the outside of the liquid outlet tube, and a sealing cap is engaged at the tail end of the liquid outlet tube. After removing the sealing cap, the liquid is easily filtered out by the metal filter screen inside the liquid outlet tube, which is convenient for use in traditional Chinese medicine testing. Furthermore, the screwing block can be rotated to remove the external threaded sleeve from the dregs cleaning port.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. Add the pulverized Chinese medicinal materials into the preparation cylinder through the addition port and add a measured amount of water. Add the prepared ethanol solvent to the solvent measuring cylinder in advance for accurate measurement. Open the control valve on the connecting pipe to add the measured amount of ethanol solvent into the preparation cylinder. Use a servo motor to drive the stirring blades on the stirring rod to rotate, so as to quickly and evenly stir the raw materials. Use a temperature controller to automatically control the electric heater to keep the mixture of medicine and liquid in the preparation cylinder at a constant temperature. Under the action of ethanol solvent, the effective components in the Chinese medicinal materials dissolve into the mixture.
[0015] 2. Pressure is released through the pressure relief valve during the preparation process to ensure the stability inside the preparation cylinder. After preparation is completed, the sealing cap is removed. Due to the metal filter screen in the liquid outlet pipe, the liquid is easily filtered and flows out for use in traditional Chinese medicine testing. The external threaded sleeve is removed from the dregs cleaning port by rotating the screw block, which facilitates the cleaning of dregs from the dregs cleaning port. Attached Figure Description
