Description

Technical Field

[0001] The utility model relates to the field of dissolution equipment, in particular to a dissolution cup cover with an automatic adjustment function. Background Art

[0002] The drug dissolution apparatus is an in vitro test instrument that simulates the disintegration and dissolution of drugs under different conditions in the human body. The experimental process is generally that the staff places the drug in a dissolution cup filled with a solvent, then covers and closes the cup to make it sealed, and then observes and records the dissolution of the drug inside the dissolution cup.

[0003] A lot of improvements have been made to the existing dissolution cup covers. The original manual cup cover structure has been changed to a mechanical one, which is more convenient and quick. For example, the automatic opening and closing dissolution cup cover device of the reciprocating cylinder dissolution instrument with patent number 202222359022X can open the beakers on both sides by setting an opening and closing mechanism, which can pull the two flip plates to flip in reverse. The opening and closing operation is simpler, the manufacturing cost is lower, and the maintenance is convenient. A lifting and adjusting mechanism is set to drive the lifting support platform, and the beaker can be lifted from the fixed ring for easy picking, thereby improving work efficiency.

[0004] However, it was found during actual use that if the size of the dissolution cup changes, the lid of the dissolution cup cannot be closed tightly, resulting in the inability to seal the dissolution cup and the evaporation of the solvent. In addition, manual introduction is required when adding the solvent, and multiple dissolution cups need to be repeated multiple times. The existing method of adding solvent is time-consuming and labor-intensive. Utility Model Content

[0007] Preferably, the dissolution cup cover is provided with a first cleaning nozzle hole and a first medium nozzle hole, and the dissolution cup support frame is provided with a second cleaning nozzle hole and a second medium nozzle hole, the size and position of the first cleaning nozzle hole correspond to those of the second cleaning nozzle hole, the size and position of the first medium nozzle hole correspond to those of the second medium nozzle hole, a cleaning nozzle is connected to the inner wall of the first cleaning nozzle hole, one end of the cleaning nozzle is located below the dissolution cup cover, and the other end of the cleaning nozzle passes through the second cleaning nozzle hole and is located above the dissolution cup support frame, a medium nozzle is connected to the inner wall of the first medium nozzle hole, one end of the medium nozzle is located below the dissolution cup cover, and the other end of the medium nozzle passes through the second medium nozzle hole and is located above the dissolution cup support frame.

[0008] Preferably, the cleaning nozzle and the medium nozzle are respectively clearance-matched with the second cleaning nozzle hole and the second medium nozzle hole.

[0009] Preferably, the first cleaning nozzle hole and the first medium nozzle hole are respectively located on the left and right sides of the first paddle rod slot.

[0010] Preferably, the dissolution cup cover plate is a truncated cone structure that is high in the middle and low around.

[0011] The beneficial effects of the utility model are:

[0012] 1. A dissolution cup support frame is arranged above the dissolution cup cover plate, and a spring is used to connect the dissolution cup cover plate and the dissolution cup support frame. The dissolution cup support frame is moved to seal the dissolution cup cover plate and the dissolution cup. Even if the dissolution cup is small, the problem of the dissolution cup and the dissolution cup cover plate being unable to close will not occur.

[0013] 2. By setting the medium nozzle hole and the cleaning nozzle hole on the dissolution cup cover plate and the dissolution cup support frame, and setting the medium nozzle and the cleaning nozzle, the staff can add solvent to the dissolution cup through the medium nozzle, and can also use the cleaning nozzle to rinse the sampling needle and the rotating paddle.
