Description

Technical Field

[0001] This utility model relates to the field of experimental dissolution equipment technology, and in particular to a pharmaceutical experimental dissolution device. Background Technology

[0002] In drug development and testing, drug dissolution is a fundamental and crucial step, directly impacting the accuracy and reliability of subsequent experimental results such as efficacy evaluation, component analysis, and dosage form development. Whether it's solvent dissolution of solid drugs, dilution and mixing of liquid drugs, or homogenization of suspensions, all processes must be carried out under stable and controllable conditions to ensure that the solute is fully dissolved and forms a homogeneous solution system.

[0003] Currently, existing drug dissolving devices have certain limitations in practical applications. Most traditional dissolving devices are equipped with dedicated dissolving cylinders as containers, but they are poorly adapted to Erlenmeyer flasks commonly used in pharmaceutical experiments. In experimental operations, researchers often prefer to use Erlenmeyer flasks as dissolving containers for ease of sampling, transfer, and compatibility with other experimental instruments. However, existing dissolving devices cannot directly and stably fix Erlenmeyer flasks for efficient dissolution. This forces researchers to first dissolve the drug in a dedicated dissolving cylinder and then transfer the solution to the Erlenmeyer flask. This process not only increases the complexity of the operation and prolongs the experimental time, but more importantly, frequent solution transfers can easily lead to sample loss, increased risk of contamination, and concentration deviations, adversely affecting the accuracy of experimental results.

[0004] Therefore, this application proposes a pharmaceutical experimental dissolution device to solve the above problems. Utility Model Content

The telescopic rod 72 is L-shaped, and its horizontal bar extends into the fixed frame 71. The lower end of the fixed frame 71 is fixedly connected to the output end of the auxiliary motor 6. A locking bolt 73 is provided on the outside of the fixed frame 71. One end of the locking bolt 73 near the fixed frame 71 passes through the side wall of the fixed frame 71 and abuts against the side wall of the telescopic rod 72. The locking bolt 73 is threadedly connected to the side wall of the fixed frame 71. By adjusting the position of the telescopic rod 72 and the fixed frame 71, the distance between the support cylinder 74 and the output end of the auxiliary motor 6 can be adjusted, thereby adjusting the amplitude of shaking of the dissolving bottle 8. The telescopic rod 72 is L-shaped, and a support cylinder 74 is fixedly connected to the upper end of the longitudinal side wall of the telescopic rod 72. The lower end of the dissolving bottle 8 extends to the inner side of the support cylinder 74, and the lower side wall of the support cylinder 74 is inclined downward on the side near the output end of the auxiliary motor 6. An electric heating plate 13 is installed inside the lower side wall of the support cylinder 74. During the dissolution process, the temperature of the dissolution bottle 8 is raised and controlled, thereby increasing the dissolution speed. Several abutting rubber rings 75 are fixedly connected to the inner side wall of the support cylinder 74. When the dissolution bottle 8 is placed inside the support cylinder 74, the inner end of the abutting rubber ring 75 abuts against the outer side wall of the dissolution bottle 8, thereby cooperating with the top limiting mechanism 10 to improve the stability of the dissolution bottle 8. The top limiting mechanism 10 includes a sliding plate 102 and two auxiliary plates 101. The rear end of the sliding plate 102 is located between the two auxiliary plates 101. A limiting slide 9 is provided on the rear side wall of the equipment frame 1, located between the two auxiliary plates 101. The front end of the sliding plate 102 passes through the limiting slide 9 and is hinged to a connecting plate 105. A rubber band 106 is fixedly connected to the end of the connecting plate 105 away from the sliding plate 102. A limiting outer ring 107 is fixedly connected to the front end of the rubber band 106.

The inner diameter of the rubber abutment ring 75 is smaller than the inner diameter of the limiting outer ring 107. The inner wall of the rubber abutment ring 75 abuts against the outer wall of the dissolving bottle 8. The upper end of the lower auxiliary plate 101 is fixedly connected to the limiting slide rod 103. The upper end of the limiting slide rod 103 passes through the sliding plate 102 and is connected to the lower end of the top auxiliary plate 101.

The upper and lower ends of the abutment spring 104 are fixedly connected to the lower end of the upper auxiliary plate 101 and the upper end of the sliding plate 102, respectively. The limiting outer ring 107 and the contact rubber ring 108 are fitted on the upper end of the dissolving bottle 8. The inner end of the contact rubber ring 108 abuts against the outer wall of the dissolving bottle 8. Under the action of the abutment spring 104, the contact rubber ring 108 and the limiting outer ring 107 apply a downward force to the dissolving bottle 8. In conjunction with the bottom support mechanism 7, the position of the dissolving bottle 8 is restricted, thereby ensuring the stability of the dissolving bottle 8 during shaking. A spring rope 11 is fixedly connected to the upper end of the limiting outer ring 107. An auxiliary stirring rod 12 is fixedly connected to the end of the spring rope 11 away from the limiting outer ring 107. The lower end of the auxiliary stirring rod 12 extends into the dissolving bottle 8. When the auxiliary motor 6 drives the bottom support mechanism 7 to shake, the auxiliary stirring rod 12 is inserted into the dissolving bottle 8.

A temperature detection sensor is installed at the position of the electric heating plate 13, and the temperature detection sensor is electrically connected to the controller.

[0019] Working principle: In use, place the material to be dissolved into the dissolving bottle 8, loosen the locking bolt 73, and adjust the position of the telescopic rod 72 and the fixing frame 71 to adjust the distance between the support cylinder 74 and the output end of the auxiliary motor 6, thereby adjusting the shaking amplitude of the dissolving bottle 8; after position adjustment, tighten the locking bolt 73, place the dissolving bottle 8 containing the reagent to be dissolved into the support cylinder 74, with the lower end of the dissolving bottle 8 abutting against the lower inner wall of the support cylinder 74, and several abutting rubber rings 75 abutting against the outer wall of the dissolving bottle 8, while simultaneously setting the limiting outer ring 107 and the contact rubber ring 108. The rubber ring 108, fitted onto the upper end of the dissolving bottle 8, abuts against the outer wall of the dissolving bottle 8. Under the action of the abutment spring 104, the rubber ring 108 and the limiting outer ring 107 apply a downward force to the dissolving bottle 8. This, in conjunction with the bottom support mechanism 7, restricts the position of the dissolving bottle 8, ensuring its stability during shaking. Simultaneously, when the bottom support mechanism 7 is shaken by the auxiliary motor 6, the auxiliary stirring rod 12 is inserted into the dissolving bottle 8. During the shaking process, the solution collides with the auxiliary stirring rod 12, further increasing the dissolving speed. The shaking time and the rotation speed of the auxiliary motor 6 are set on the operation screen 3. During shaking, the auxiliary motor 6 operates by rotating in both forward and reverse directions. The liquid in the dissolving bottle 8 is more easily agitated during the rotation of the auxiliary motor 6, facilitating the dissolution of the reagent. An electric heating plate 13 is installed at the bottom of the support cylinder 74. During the dissolution process, the temperature of the dissolving bottle 8 is raised and controlled, thereby increasing the dissolution speed.
