Description

Technical Field

[0001] The utility model relates to the technical field of Chinese medicinal material detection sample processing, in particular to a Chinese medicinal material detection sample preprocessing device. Background Art

[0002] Chinese medicinal materials refer to native medicinal materials used under the guidance of traditional medicine to treat diseases. However, due to the influence of external growth factors such as the place of origin, there are certain differences in the internal composition of the same medicinal materials.

[0003] Before Chinese medicinal materials are processed and used, samples of the same medicinal materials from multiple origins of the same batch are usually taken for testing. The testing process mostly requires decoction, and then the medicinal liquid is tested. Most existing decoction methods use an alcohol lamp to heat a beaker or test tube to complete the decoction of a small amount of medicinal materials. However, in actual use, an alcohol lamp can only heat one test tube or beaker, and the test samples are usually large in number. Multiple alcohol lamps are used to heat multiple containers, which poses certain safety hazards. In addition, there must be certain differences in the decoction of multiple containers. These differences will cause deviations in the sample testing process and affect the test results. Utility Model Content

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0005] In actual use, one alcohol lamp can only heat one test tube or beaker, but the number of test samples is usually large, and multiple alcohol lamps will be used to heat multiple containers, which poses certain safety hazards. In addition, there will inevitably be certain differences when boiling multiple containers separately. These differences will cause deviations in the sample testing process and affect the test results.

[0006] In order to solve the problems existing in the prior art, the utility model provides a sample pretreatment device for Chinese medicinal materials testing, including a box body, a sealing cover is provided on the top of the box body, a slot is provided at the bottom of the sealing cover, a placement plate is clamped on the inner wall of the box body, a test tube is inserted inside the placement plate, a support foot is provided on the side of the bottom of the box body close to the test tube, a partition is provided on the inner wall of the box body, heating wires are provided on the inner wall of the box body and the surface of the partition, and the end of the heating wire is electrically connected to a control device.

[0007] The utility model provides a sample pretreatment device for Chinese medicinal material detection.

[0008] Furthermore, the box body is made of a temperature-resistant material as a whole, a temperature-resistance layer is arranged on its inner wall, a heating wire is arranged on the surface of the temperature-resistance layer, and a rectangular protrusion is arranged on one side of the inner wall of the box body close to the top.

[0009] Furthermore, the placement plate is a perforated plate made of a temperature-resistant hard rubber material with perforations on the surface and edges, and the perforations on the surface of the placement plate are adapted to the test tubes, and the bottom of the placement plate contacts the rectangular protrusions on the inner wall of the box body.

[0010] Furthermore, the slot at the bottom of the cover is an annular groove structure, which is integrally matched with the open end of the test tube, and the inner wall of the slot is wavy on one side close to the inner wall of the test tube.

[0011] Furthermore, the support leg is composed of six radially arranged cylindrical rod-shaped structures with depressions on the tops, and the depressions on the tops thereof are adapted to the bottoms of the test tubes and in contact with the test tubes.

[0012] Furthermore, the partition is a plate-like structure arranged in the horizontal direction of the box body, a through groove is opened on its surface, and a gap is left between the bottom and the inner wall of the box body.

[0013] Furthermore, the heating wires are arranged in a wavy shape on both sides of the inner wall of the box body and the surface of the partition. There are three heating wires in total. The ends of the three heating wires pass through the box body and are connected to the control device. The outer side of the part of the heating wire passing through the box body is covered with a barrier material.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The utility model fixes the test tube by clamping a placement plate inside the box body and inserting the test tube into the placement plate. After putting medicine and water into the test tube, the box body is filled with water and the cover is closed. The slot at the bottom of the cover is adapted to the test tube to seal the top opening of the test tube. A gap is left between the wavy inner wall of the slot and the test tube to ensure that the pressure generated by the high temperature inside the test tube can be discharged outward. Subsequently, the electric heating wire is started by the control device, and the electric heating wire heats the water in the box body until the water boils. The boiling water heats up the test tube, and the water in the test tube boils accordingly to decoct the medicine. The heating speed of each test tube in the box body is the same, so that the difference in heating between the decoctionated medicines is avoided to the greatest extent, and multiple samples can be processed at the same time, thereby improving work efficiency.
