Description

Technical Field

[0001] The utility model relates to the technical field of detection equipment, in particular to a capsule release rate measuring device. Background Art

[0002] Release rate refers to the rate and extent of release of an oral drug from a sustained-release, controlled-release, or enteric-coated formulation in a specified solvent. Determination of release rate is an essential and important step in drug development and production.

[0003] Capsule release rate is usually determined using the basket method. The capsule to be measured is placed in a dissolution beaker, which is then placed in a water bath and stirred with a stirring rod to simulate the human body environment. Testers then extract samples based on time periods and store them for convenience in a series of subsequent tests. However, in actual use, there are some functional deficiencies and room for improvement. For example, the dissolution beaker itself is made of glass. After the dissolution solution is injected into it, it has a certain weight and is stuck in the notch at the top of the water bath. After the measurement is completed, it is not easy to remove. The operator needs to pinch the edge of the beaker with his fingers and lift it up, which is quite laborious and does not provide a function for facilitating the extraction of the beaker.

[0004] Now, a new type of capsule release rate measuring device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1: Please refer to Figure 1-4 , a capsule release rate measuring device, comprising a bottom shell 1, a fixed cylindrical shell 2 is fixedly connected to the left side of the top of the bottom shell 1, a movable cylindrical shell 3 is sleeved on the top of the fixed cylindrical shell 2 from top to bottom, the top of the movable cylindrical shell 3 is fixedly connected to the top shell 5, the bottom end of the fixed cylindrical shell 2 is installed with an electric cylinder 4, a reduction motor 6 is installed on the right side of the top of the top shell 5, and a stirring paddle 7 is fixedly connected to the output end of the reduction motor 6, a water bath 12 is fixedly connected to the right side of the top of the bottom shell 1, a beaker socket 13 is provided at the top of the water bath 12, a measuring beaker 14 is inserted into the inside of the beaker socket 13 from top to bottom, a beaker edge 15 is fixedly connected to the top of the measuring beaker 14, electric heating rods 22 are respectively installed on both sides of the bottom end of the water bath 12, a controller 25 is provided at the front end of the bottom shell 1, and a lifting component for facilitating the removal of the beaker is provided at the top of the beaker edge 15;

[0026] See also Figure 1-4 A capsule release rate measuring device also includes a pulling assembly, which includes a stainless steel ring 11, which is fixedly connected to the top of the beaker edge 15. Two sets of fixing rods 8 are vertically fixedly connected to the right side of the bottom of the top shell 5. The bottom end of the fixing rod 8 is welded with an arc plate 9, and the bottom end of the arc plate 9 is fixedly connected to two sets of electromagnets 10.

[0027] The fixing rods 8 are symmetrically arranged about the vertical centerline of the measuring beaker 14. The bottom end of the arc-shaped plate 9 is higher than the top end of the water bath 12. The electromagnet 10 and the controller 25 are electrically connected. The position and size of the electromagnet 10 correspond to the position and size of the stainless steel ring 11. The outer diameter of the stainless steel ring 11 is the same as the outer diameter of the beaker rim 15. The inner diameter of the stainless steel ring 11 is the same as the inner diameter of the measuring beaker 14, making it easy to lift the beaker.

[0028] Specifically, if Figure 1 and Figure 2 As shown, during the operation, the electromagnet 10 is in a powered-on demagnetized state. After the operation is completed, the beaker needs to be removed, and the electric cylinder 4 further retracts so that the electromagnet 10 fits the stainless steel ring 11 at the top of the beaker edge 15. The electromagnet 10 is powered off and has magnetism, which firmly adsorbs the stainless steel ring 11. As the electric cylinder 4 extends upward, the measuring beaker 14 can be lifted from the beaker socket 13.

[0029] Example 2: The bottom end of the measuring beaker 14 is fixedly connected to the bottom glass shell 16, and the bottom end of the bottom glass shell 16 is glued with a magnetic block 17. A stainless steel lower screen 18 is horizontally placed at the bottom end of the inside of the measuring beaker 14. Positioning rods 19 are welded on both sides of the top of the stainless steel lower screen 18. A stainless steel upper screen 20 is horizontally placed on the top of the stainless steel lower screen 18. Positioning holes 21 are respectively provided on both sides of the bottom end of the stainless steel upper screen 20. The outer diameter of the positioning rod 19 is the same as the inner diameter of the positioning hole 21. The positions of the positioning rod 19 and the positioning hole 21 correspond to each other, which is convenient for fixing the position of the capsule;

[0030] Specifically, if Figure 3 and Figure 4 As shown, the capsule is placed horizontally in the stainless steel lower screen 18, and then the stainless steel upper screen 20 is buckled on the top of the stainless steel lower screen 18. The positioning rod 19 on the stainless steel lower screen 18 is inserted into the positioning hole 21 on the stainless steel upper screen 20 to prevent the stainless steel lower screen 18 and the stainless steel upper screen 20 from being misplaced. As the stainless steel lower screen 18 and the stainless steel upper screen 20 are placed in the measuring beaker 14, the magnetic block 17 in the bottom glass shell 16 attracts the stainless steel lower screen 18 and the stainless steel upper screen 20 to prevent them from being displaced, thereby limiting the position of the capsule.

[0031] Example 3: A servo motor 23 is installed on the right side of the top end of the bottom shell 1, and a stirring impeller 24 is movably connected to the middle position of the bottom end of the water bath 12. The vertical center lines of the water bath 12, the measuring beaker 14, and the stirring impeller 24 coincide with each other. The output end of the servo motor 23 is connected to the bottom end of the stirring impeller 24, which can make the water temperature uniform;

[0032] Specifically, if Figure 1 and Figure 3 As shown, during the heating process of the electric heating rod 22, the servo motor 23 drives the stirring impeller 24 to rotate continuously, stirring the pure water in the water bath 12 and making the temperature uniform by increasing the fluidity.

[0033] Working principle: When the present invention is in use, first, the dissolution medium solution is injected into the measuring beaker 14, and then the capsule is placed in the stainless steel screen, and then put into the measuring beaker 14 together with the stainless steel screen, and the measuring beaker 14 is inserted along the beaker socket 13 at the top of the water bath 12. The electric heating rod 22 heats the pure water inside the water bath 12 to simulate the temperature of the human body. At this time, the electric cylinder 4 retracts, and the stirring paddle 7 extends into the measuring beaker 14. The reduction motor 6 drives the stirring paddle 7 to rotate continuously to stir the medium solution. The operator regularly collects the medium solution for sampling and analysis. During the operation, the electromagnet 10 is in an energized and demagnetized state. After the operation is completed, the beaker needs to be removed, and the electric cylinder 4 further retracts so that the electromagnet 10 fits the stainless steel ring 11 at the top of the beaker edge 15. The electromagnet 10 is magnetic when it is powered off, and the stainless steel ring 11 is firmly adsorbed. As the electric cylinder 4 extends upward, the measuring beaker 14 can be lifted from the beaker socket 13. When placing the capsule, it is placed horizontally within the stainless steel lower screen 18. The stainless steel upper screen 20 is then buckled onto the top of the stainless steel lower screen 18. The positioning rod 19 on the stainless steel lower screen 18 is inserted into the positioning hole 21 on the stainless steel upper screen 20 to prevent the stainless steel lower screen 18 and the stainless steel upper screen 20 from being misaligned. As the stainless steel lower screen 18 and the stainless steel upper screen 20 are placed into the measuring beaker 14, the magnetic block 17 within the bottom glass shell 16 attracts the stainless steel lower screen 18 and the stainless steel upper screen 20, preventing them from shifting, thereby limiting the position of the capsule. During the stirring and dissolution process, the electric heating rod 22 generates heat to heat the purified water in the water bath 12, keeping it at a constant temperature. During the heating process, the servo motor 23 drives the stirring impeller 24 to rotate continuously, stirring the purified water in the water bath 12 and making it temperature-uniform by increasing fluidity.

[0034] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
