Abstract
The utility model discloses a sealing cup cover for dissolution of pharmaceutical dissolution tester, which comprises an upper cover and a lower cover. An open groove with the width of D is respectively arranged in the radial direction along the center of the lower cover and the upper cover. In order to closely coincide and relatively rotate the center of the upper and lower covers, a convex platform with the height of 2 to3mm is positioned along the outside diameter of the lower cover of the sealing cup cover. A drug delivery hole and a sampling hole are positioned on the upper cover; a round hole of similar diameter is also positioned on the open groove of the lower cover. The dissolution cup sealing cup cover is made of engineering plastic. The utility model has the advantages that: it prevents the influence to the testing result due to the evaporation of the dissolution medium and, at the same time, simplifies the complicated operation as no fluid replacement is needed. With simple structure and convenient operation, the utility model can meet with the requirements for pharmaceutical dissolution experiment stated in national pharmacopoeia.
Description
Technical field
The utility model relates to and belongs to the drug test device, is specifically related to the stripping rotor bowl cover in the drug dissolution detector.
Technical background
Stripping rotor is one of main device in the drug dissolution detector, and the structural design of stripping rotor and bowl cover thereof should meet the drug dissolution test condition of pharmacopeia regulation, also will consider the convenience of experimental implementation simultaneously.But present employed stripping rotor bowl cover has certain defective, show that mainly the fluting and the thief hole that (are used to pack loom into or change the basket bar) on the bowl cover belong to open, make the dissolution medium in the stripping rotor evaporate easily, in the medicine dissolution test, must constantly carry out fluid infusion, so both make the loaded down with trivial details inconvenience of test operation, reduced the accuracy that dissolution rate detects again.Proposition of the present utility model can make this problem obtain satisfied solution.
Summary of the invention
The purpose of this utility model provides the stripping rotor bowl cover in a kind of medicine stripping detector with sealing function.
Structure of the present utility model as shown in drawings.The stripping rotor sealed cup cover is made up of loam cake 1 and lower cover 2 two parts, and two parts are the dish structure, can the as a whole bowl cover of overlapping applying.It is the open slot of D that radially there is a width at lower cover 2 centers of sealed cup cover, and it is the open slot of D that radially also there is same widths at loam cake 1 center of sealed cup cover.For the center that makes upper and lower cover accurately overlaps and can rotate relatively, being provided with along the external diameter of sealed cup cover lower cover 2 highly is the boss 3 of 2～3mm.Loam cake 1 outer through equaling the internal diameter of lower cover 2 convex platforms 3, the thickness of loam cake 1 equals the height of boss 3 substantially.Be convenient throw in experiment medicine and sampling at any time, be provided with offer medicine hole 4 and thief hole 5, the circular hole of same diameter is also arranged on the fluting of lower cover 2 at the loam cake 1 of sealed cup cover.The upper and lower cover of stripping rotor sealed cup cover is made by engineering plastics.When carrying out medicine stripping/release test, the upper and lower cover of bowl cover is stacked as one and rotation overlaps its open slot, make open slot be inserted in the boss that loom places on the stripping rim of a cup and pushes down the lower cover edge with the compression cup piece, loam cake is rotated about 180 degree relatively, the diameter of its center hole is suitable with the diameter of loom, does not influence the loom rotation and tests.
Description of drawings
Accompanying drawing 1 is a three-dimensional structure diagram of the present utility model.
Accompanying drawing 2 is for having the stripping rotor stereographic map of stripping rotor bowl cover.
Embodiment
Below in conjunction with accompanying drawing and by specific embodiment the utility model is described further.
The stripping rotor bowl cover is made by engineering plastics, and the stripping rotor volume is 1000ml, and the stripping rotor bottom is a semisphere.Internal diameter 102mm: high 168mm (as Fig. 2).The width D of bowl cover upper and lower cover open slot is according to the diameter design of changeing the basket bar, present embodiment D=12mm.The stripping rotor bowl cover directly is placed on the stripping rotor, stripping rotor is placed in the water bath with thermostatic control of dissolution rate apparatus, guarantee that the central axis of each stripping rotor and the axis deviation of the molten instrument transfer of medicine basket bar turning axle all are not more than 2mm, amplitude of fluctuation is disalignment 1.0mm not.At first the upper and lower cover of bowl cover being stacked as one and rotation overlaps its open slot, make open slot be inserted in the boss that loom places on the stripping rim of a cup and pushes down the lower cover edge with the compression cup piece, loam cake is rotated about 180 degree relatively, the diameter of its center hole is suitable with the diameter of loom, not influencing the loom rotation tests, because bowl cover is in sealing state, can effectively prevent the medium evaporation.The 45 ° of tablets of hole dextrorotation of when throwing in test sample loam cake being offerd medicine can fall into stripping rotor from the slotted eye of lower cover.The slotted eye of itself and lower cover is aligned left-handed 45 degree of loam cake thief hole and can carry out sampling operation.
Characteristics of the present utility model are: avoided affecting because the dissolution medium evaporation causes the result to test, simultaneously because need not Fluid infusion and simplified troublesome operation. The utility model structure is very simple, and is easy to operate, can satisfy again NF rule Fixed medicine dissolving out experimental requirement.
