Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical laboratory equipment technology, and in particular to a disintegration device for drug detection. Background Technology
[0002] Disintegration refers to the complete disintegration or fragmentation of oral solid dosage forms under specified conditions. Except for insoluble coating materials or broken capsule shells, all fragments should pass through a sieve. If a small amount fails to pass through the sieve but has softened or floated lightly without a hard core, it can be considered compliant. The disintegration time test is used to examine the disintegration of oral solid dosage forms under specified conditions. The disintegration time test is applicable to tablets (including regular tablets, film-coated tablets, sugar-coated tablets, enteric-coated tablets, colon-targeted enteric-coated tablets, lozenges, sublingual tablets, and effervescent tablets), capsules (including hard capsules, soft capsules, and enteric-coated capsules), and pellets.
[0003] A disintegration apparatus is an instrument used to test disintegration time. Generally, oral tablets should disintegrate in a medium under specified conditions and within a specified time. The method for testing disintegration time is as follows: Take one tablet and place it in a glass tube in a basket, one tablet in each tube. Then, start the disintegration apparatus, immersing the basket in a 1000°C beaker filled with water at 37±1°C. Within the specified water level and vertical movement distance, the apparatus should move back and forth at a speed of 30-32 times per minute. Generally, each compressed tablet should completely dissolve or disintegrate into fragments within 15 minutes and pass through a sieve. For sugar-coated tablets, extract tablets, or film-coated tablets, the disintegration time should be tested using the same method; they should completely dissolve or disintegrate through a sieve within one hour (excluding insoluble coating fragments).
[0004] During use, the disintegration apparatus needs to heat and keep the liquid in the beaker at a constant temperature by means of water bath heating. The heating method of the existing disintegration apparatus is mostly to use heating tubes to directly heat the water outside the beaker. Due to the concentrated heating position, the liquid in the beaker may be heated unevenly and the uniformity may not be strong, thus affecting the disintegration test results of the drug.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0028] Example 1:

[0030] Water bath 3 is fixedly connected to the body 1;
[0031] Beaker 4 is rotatably connected to water bath 3;
[0032] Bracket 8 is rotatably connected to water bath 3;
[0033] The limiting rod 9 is fixedly connected to the bracket 8, and the limiting rod 9 abuts against the bottom wall of the beaker 4.
[0034] A connecting rod 7 is rotatably connected to the water bath 3, and a support rod 702 is fixedly connected to the connecting rod 7. The support rod 702 and the limiting rod 9 are fixedly connected.

[0036] A rubber ring 801 is fixedly connected to the bracket 8, and the rubber ring 801 abuts against the side wall of the beaker 4.
[0037] Reference Figure 4The rubber ring 801 set on the bracket 8 can effectively hold the bottom of the beaker 4, thereby improving the stability of the beaker 4 when it rotates.

[0039] Reference Figures 1-5 During use, beaker 4 is placed in water bath 3, and the medicine is placed in the glass tube of basket 201. At this time, the heating function of water bath 3 is started. After heating for a period of time, drive motor 6 is started. Drive motor 6 will drive drive rod 601 connected to its drive end to rotate. The rotation of drive rod 601 will drive connecting rod 7 to rotate. The rotation of connecting rod 7 will drive support rod 702 to rotate, thereby driving beaker 4 to rotate at a uniform speed. The rotation of beaker 4 will improve the heating efficiency and effect of the liquid in beaker 4 and improve the uniformity of the liquid in beaker 4.
[0040] Reference Figure 4 When the connecting rod 7 rotates, it will also drive the stirring blade 701 to rotate. The rotation of the stirring blade 701 will disturb the water in the water bath 3.

[0045] A limiting ring 401 is fixedly connected to the side wall of beaker 4, and the limiting ring 401 and the rotating ring 5 abut against each other.
[0046] Reference Figure 2 By setting a limiting ring 401 fixedly connected to the side wall of beaker 4, the stability of beaker 4 can be improved and the safety of beaker 4 can be improved when it rotates.
[0047] This invention, by rotating the beaker 4, enables the liquid inside the beaker 4 to be heated evenly, thereby improving the uniformity of the liquid inside the beaker. This effectively solves the problem in the prior art where the liquid in the beaker is not heated evenly and the uniformity is not strong, thus affecting the disintegration test results of the drug.
