Description

Technical Field

[0001] This utility model relates to the field of drug dissolution equipment technology, and in particular to a transparent, tumbler-type drug dosing device adapted for use with a dissolution apparatus. Background Technology

[0002] In drug dissolution testing, the administration of liquid drugs is a crucial step. Traditional administration methods typically rely on manual operation, but this method generally suffers from the following problems:

[0003] 1. Inaccurate dosing position: Traditional manual liquid dosing operations usually use a syringe to manually inject the sample into the dissolution vessel from above. This operation is prone to poor repeatability of experimental results due to differences in the force (speed) and angle of sample injection.

[0004] 2. May cause data (sample) loss: Another type of liquid dosing device is usually a flat-bottomed cylindrical dosing cup. After entering the dissolution cup, the dosing cup is easily affected by the internal solvent and may invert, preventing the sample in the cup from being released and resulting in the scrapping of data and samples.

[0005] 3. Low level of automation: Traditional manual liquid dosing usually requires multiple people to operate and complete 8-12 samples. This operation is extremely labor-intensive and accompanied by unpredictable differences in dosing time. Utility Model Content

[0034] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0035] As attached Figure 1-6 As shown, this utility model provides a transparent, self-righting dosing device adapted for use with a dissolution apparatus, comprising:

[0036] Dissolution cup lid 1;

[0037] The quick-release synchronous dosing device 2 is located on the top of the dissolution cup lid 1 and is slidably connected to the dissolution cup lid 1.

[0038] The dosing hole 6 is located on the quick-release synchronous dosing device 2;

[0039] Dissolution cup 5 is located at the bottom of dissolution cup lid 1 and is detachably connected to dissolution cup lid 1;

[0040] The cup opening is set on the dissolving cup lid 1, and the cup opening connects the dissolving cup 5 at the bottom of the dissolving cup lid 1 with the outside world;

[0041] The dosing cup 3 is set inside the dosing hole 6. The dosing cup 3 is a hollow cylinder. The bottom of the dosing cup 3 is provided with a semi-circular body. The semi-circular body increases the counterweight at the bottom of the dosing cup 3 and improves the stability of the dosing cup 3 when dosing.

[0042] The driving device is used to drive the quick-release synchronous dosing device 2 to slide on the dissolution cup lid 1, so that the quick-release synchronous dosing device 2 is close to or away from the cup opening.

[0043] In actual use, the operator first installs the device on the dissolution apparatus and adds the liquid sample to be tested into the dosing cup 3. Then, the dosing cup 3 is placed into the dosing hole 6 of the quick-release synchronous dosing device 2. At this time, the quick-release synchronous dosing device 2 is in its initial position, and the bottom of the dosing cup 3 is in contact with the dissolution cup lid 1, and it does not tip over under the influence of the dosing hole 6. Next, according to the experimental requirements, the automatic dissolution experiment is set and executed in the dissolution apparatus. When the dissolution experiment reaches the dosing point, the drive device drives the quick-release synchronous dosing device 2 to move towards the cup opening. When the dosing hole 6 coincides with the cup opening, the dissolution cup lid 1 no longer supports the dosing cup 3, and the dosing cup 3 falls from the dosing hole 6 into the cup opening, and further falls vertically into the dissolution cup 5. After the dosing cup 3 falls to the bottom of the cup, the dosing cup 3 tilts to one side, and the liquid sample to be tested is released from the dosing cup 3 to carry out the dissolution experiment.

[0044] Specifically, both the dissolution cup 5 and the dosing cup 3 are made of transparent material.

[0045] In this embodiment, a dosing cup fixing device 4 is provided inside the dosing hole 6. The dosing cup fixing device 4 is provided with a through hole. The diameter of the through hole is adapted to the dosing cup 3. The outer contour of the dosing cup fixing device 4 is adapted to the dosing hole 6.

[0046] After the dosing cup 3 is placed into the dosing hole 6, the staff can insert the dosing cup fixing device 4 through the dosing cup 3 into the dosing hole 6, so that the dosing cup 3 is fixed in the through hole of the dosing cup fixing device 4, ensuring that the dosing cup 3 moves parallel without angular deflection during the movement, so that it eventually falls vertically into the dissolution cup 5.

[0047] Specifically, the diameter of the semicircle is larger than the diameter of the dosing cup 3, and one flat end of the semicircle is close to the dosing cup 3, forming a platform at the bottom of the dosing cup 3 to ensure that the liquid medicine will not spill during transportation after being filled into it.

[0048] Specifically, the inner wall of the dosing hole 6 is provided with a stepped groove, and the outer wall of the dosing cup fixing device 4 is provided with a step that is compatible with the stepped groove.

[0049] Preferably, the height of the dosing cup fixing device 4 is adapted to the height of the cylinder of the dosing cup 3, and the height of the dosing hole 6 is adapted to the height of the dosing cup 3 plus the semi-circular body.

[0050] In another embodiment, the driving device includes:

[0051] A drive motor is mounted on the dissolution cup lid 1.

[0052] A rack is installed at one end of the quick-release synchronous dosing device 2;

[0053] The gear is coaxially mounted on the output shaft of the drive motor and meshes with the rack.

[0054] This drives the gear to rotate via the drive motor, which in turn drives the rack to move in parallel, causing the quick-release synchronous dosing device 2, which is fixedly connected to the rack, to slide on the dissolution cup lid 1.

[0055] Specifically, a slide is provided on the dissolution cup lid 1, and the quick-release synchronous dosing device 2 is slidably connected to the slide.

[0056] In another embodiment, the dissolution cup lid 1 is provided with multiple cup openings and quick-release synchronous dosing devices 2 and driving devices corresponding to the multiple cup openings, so as to simultaneously dosing drugs into multiple dissolution cups 5.

[0057] In another embodiment, the dissolution cup lid 1 is provided with multiple cup openings, and the quick-release synchronous dosing device 2 is provided with dosing holes 6 corresponding to the multiple cup openings, so as to simultaneously dosing drugs into multiple dissolution cups 5.

[0058] In another embodiment, the drive device is electrically connected to a control template, which allows staff to set the dosing time. Once the dosing time is reached, the drive device is automatically activated, improving the automation and efficiency of the experiment.
