Description

Technical Field

[0001] The utility model belongs to the technical field of drug detection, in particular to a quantitative titration device for drug detection. Background Art

[0002] Titration device for drug testing: It is an experimental device used to accurately determine the concentration of components in liquid samples. It is widely used in the fields of chemical analysis and quality control. The device is usually composed of components such as a burette, a conical flask, a bottle transfer device, a sensor, and a control system. It can realize an efficient and automated titration process. At the same time, the equipment is equipped with a real-time data monitoring function, which can record and display key parameters in the titration process in real time, facilitating subsequent data analysis and result verification.

[0003] Existing titration devices for drug testing are typically equipped with only a single burette, a design that limits their efficiency in testing multiple titrants. Since they can only store a single titrant to be tested, operators must frequently replace the drug solution when performing multiple tests using different titrants. This process is not only cumbersome but may also adversely affect the reaction between the titrant and the drug. Furthermore, existing titration devices typically rely on manual control of the titrant dosage during titration. This manual operation not only easily leads to inaccurate titrant dosage but can also introduce human errors due to improper operation, affecting the reaction effect.

[0004] To this end, we provide a quantitative titration device for drug testing to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to provide a quantitative titration device for drug testing. Through the cooperation of a bottle transfer component and a quantitative component, the problem that the titration device for drug testing in the prior art is inconvenient for multiple titrations and cannot accurately control the titration amount of the titrant is solved.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Specific embodiment 1

Both sides of the surface of the two-way screw 5 are threadedly connected to a sliding sleeve 6, and the top of the sliding sleeve 6 is fixedly connected to an arc splint 7, one end of the two-way screw 5 is fixedly connected to a rotating rod 8, and a sliding part is provided in the inner cavity of the base 1; a quantitative assembly is provided at the bottom of the liquid storage bottle 3, and the quantitative assembly includes a burette 9, which is connected to the bottom of the liquid storage bottle 3, and a scale line 10 is provided on the surface of the burette 9. A metering valve 11 is installed on one side of the surface of the burette 9, and a valve 12 is installed on the other side of the surface of the burette 9.

[0028] Specifically: There are three liquid storage bottles 3, each of which can store a titrant, so as to avoid the need to frequently clean and replace the titrant when titrating multiple titrants. The bottom of the slide 4 fits and slides with the movable groove of the inner cavity of the base 1 to limit the slide 4. A limiting groove is provided at the top of the inner cavity of the slide 4, and the sliding sleeve 6 slides in the inner cavity of the limiting groove. One end of the bidirectional screw 5 is fixedly connected to the rotating rod 8, and one end of the rotating rod 8 extends to the outside of the slide 4. The other end of the bidirectional screw 5 is rotatably connected to one side of the inner cavity of the slide 4 through a bearing. A valve 12 is installed on the top of the surface of the burette 9 to facilitate the quantitative delivery of the titrant in the liquid storage bottle 3 to the burette 9. A metering valve 11 is installed at the bottom of the surface of the burette 9, which can quantitatively titrate the titrant in the burette 9 into the conical flask. Specific embodiment 2

[0030] See also Figure 1-4 The cam 14 is connected to the inner cavity of the sliding plate 13 and the sliding plate 4 is connected to the sliding plate 13 on the inner cavity of the sliding plate 13. The sliding plate 13 is connected to the sliding plate 13 on the inner cavity of the sliding plate 13. The sliding plate 13 is connected to the sliding plate 13 on the inner cavity of the sliding plate 13. The sliding plate 13 is connected to the sliding plate 13 on the inner cavity of the sliding plate 13. The sliding plate 13 is connected to the sliding plate 13 on the inner cavity of the sliding plate 13.

[0031] Specifically: the sliding plate 4 can be driven to move left and right in the inner cavity of the base 1 by the moving rod 14, so that the conical flask fixed on the top of the sliding plate 4 can be moved to the bottom of different burettes 9. When disassembling and assembling the liquid storage bottle 3, the bolt 17 in the inner cavity of the fixing block on one side of the limiting ring 16 can be used to limit or release the limit of the liquid storage bottle 3. One side of the inner cavity of the slide groove is connected with one side of the inner cavity of the moving groove, so that the sliding plate 4 can be driven to move by the moving rod 14.

The bottom of the sliding sleeve 6 is slidably connected to the surface of the slide bar, which can limit the sliding sleeve 6.

[0032] The working principle of the present invention is as follows: when it is necessary to perform quantitative titration detection on a drug, first place the drug to be detected in the conical flask, then place the conical flask on the top of the slide 4, and then rotate the hand wheel, the hand wheel drives the rotating rod 8 to rotate, the rotating rod 8 drives the bidirectional screw 5 to rotate, the bidirectional screw 5 drives the two sliding sleeves 6 on its surface to move relatively, and the sliding sleeve 6 drives the arc-shaped splint 7 to move, so as to limit the conical flask to prevent the conical flask from tipping over during subsequent movement, then open the valve 12, and introduce the titrant in the liquid storage bottle 3 into the burette 9. After closing the valve 12, open the metering valve 11, and quantitatively add the titrant to the conical flask through the burette 9. The operator can observe the amount of each titration and the amount of the remaining titrant in the burette 9 through the scale line 10, so as to add the titrant to the burette 9 in time.

[0033] When titration of multiple titrants is required, the handle is simply pulled, and the handle drives the moving rod 14 to move, and the moving rod 14 drives the slide plate 4 to slide on the surface of the slide rod 13, so that the conical flask is moved to the bottom of different burettes 9, and then quantitative titration is performed on the conical flask through the metering valve 11.
