Description

Technical Field

[0001] This utility model relates to the field of Western medicine dissolution testing technology, specifically a Western medicine dissolution testing and analysis device. Background Technology

[0002] Dissolution rate of Western medicine refers to the rate and extent to which a drug dissolves from solid dosage forms such as tablets in a specified solvent. Dissolution rate is an important indicator for tablet quality control. Dissolution rate also refers to the rate and extent to which a drug dissolves in a specified solvent in solid dosage forms such as tablets, capsules, and granules. It evaluates the in vitro release characteristics of a formulation by simulating the disintegration and dissolution process of a drug in the human gastrointestinal tract.

[0003] When measuring the dissolution rate of Western medicine, a dissolution meter is required. Generally, the dissolution cup is placed in the base of the dissolution meter. The base is usually equipped with a corresponding tank. After the dissolution cup is placed, even though it is restricted by the tank, a gap will still be formed between the two. Therefore, after the stirring rod is working, the dissolution cup is prone to excessive shaking in the gap space, which can easily damage the dissolution cup. Utility Model Content

[0004] The purpose of this invention is to provide a Western medicine dissolution testing and analysis device to solve the problem mentioned in the background art that, even if the dissolution cup is restricted by the tank after it is placed, a gap will still be formed between the two, which makes it easy for the dissolution cup to shake excessively in the gap space after the stirring rod is working, thus easily causing damage to the dissolution cup.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Western medicine dissolution testing and analysis device, comprising a base plate, a base, and a head box. Three sets of placement slots are evenly distributed in the top of the base. Dissolution cups are contained in the placement slots. A cup rim plate is fixed to the top of the dissolution cup. Adhesive layers are coated on both sides of the bottom of the cup rim plate. Iron sheets are bonded and fixed to the bottom of the adhesive layers. Grooves are formed in the top of the base at the positions on both sides of the placement slots. Magnetic blocks are fixed in the grooves. The positions of the iron sheets and the grooves correspond one-to-one.

[0006] As a further technical solution of this utility model, the grooves are symmetrically distributed about the central axis of the placement groove, and the iron pieces are symmetrically distributed about the central axis of the cup rim plate.

[0007] As a further technical solution of this utility model, the iron sheet and the adhesive layer are bonded and fixed together, and the magnetic block and the iron sheet are magnetically attracted together.

[0008] As a further technical solution of this utility model, the lateral dimension of the cup rim plate is larger than the lateral dimension inside the placement groove, and the lateral dimension outside the dissolution cup is smaller than the lateral dimension inside the placement groove.

[0009] As a further technical solution of this utility model, an anti-slip pad is fixed to the bottom of the base plate, and anti-slip protrusions are uniformly fixed to the outer surface of the bottom of the anti-slip pad.

[0010] As a further technical solution of this utility model, an operation panel is fixed on the front end face of the machine head box, and three sets of working motors are installed on the top of the machine head box, with stirring rods being driven to the output ends of the three sets of working motors.

[0011] As a further technical solution of this utility model, a first support rod is fixed on both sides of the base, a reserved groove is opened in the first support rod, a second support rod is inserted in the reserved groove, and the top of the second support rod is fixed to the bottom of the machine head box.

[0012] As a further technical solution of this utility model, an electric telescopic rod is installed at the bottom of the second support rod, and guide rails are fixed on both sides of the inner wall of the reserved groove. Guide blocks are fixed at the lower positions on both sides of the second support rod, and the guide rails slide through the inside of the guide blocks.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this kind of Western medicine dissolution test and analysis device not only improves the stability of the dissolution cup, but also improves the height adjustment capability and bottom anti-slip effect of the Western medicine dissolution test and analysis device.

[0014] (1) By opening a placement groove in the top of the base, the placement groove is used to accommodate and place the dissolution cup. The base is transparent for staff to observe and analyze the dissolution rate. Grooves are opened in the top of the base on both sides of the placement groove. The magnetic block is fixed inside the groove. When in use, the iron sheet is glued and fixed to the bottom of the cup rim plate using an adhesive layer. Therefore, when the dissolution cup is placed, the cup rim plate is above the base, and the iron sheet is positioned in the groove and cooperates with the magnetic block to form an adsorption positioning, thereby reducing the shaking problem after the dissolution cup is placed and improving stability.

[0015] (2) By installing and fixing the first support rod on both sides of the base, and fixing the top of the second support rod at the bottom of the head box, the second support rod can be pushed up and down in the first support rod after the electric telescopic rod is started. When moving, it is guided by the guide block and the guide rail. Therefore, the height of the head box can be adjusted to achieve the purpose of adjusting the position of the stirring rod, which makes it convenient for the staff to place and pick up the dissolution cup.

[0016] (3) The anti-slip pad is glued and fixed to the bottom of the base plate by means of adhesive. At the same time, anti-slip protrusions are evenly distributed on the outer surface of the bottom of the anti-slip pad. Therefore, during use, the anti-slip pad is used to improve the anti-slip effect of the bottom. At the same time, the anti-slip protrusions further improve the anti-slip effect of the pad itself, thereby improving the stability during work. Attached Figure Description
