Abstract
Description
Technical Field
[0001] This utility model relates to a testing instrument, and more particularly to an instrument for drug dissolution testing, specifically a drug dissolution auxiliary device. Background Technology
[0002] For the dissolution testing of transdermal patches, the paddle method is usually used, which involves two layers of mesh discs. The patch to be tested is placed flat between the two mesh discs and then placed in a container containing a solution. The paddle is rotated to simulate the dissolution process of the transdermal patch on the surface of the skin.
[0003] To ensure a secure connection between the two mesh discs, a through-hole is typically provided on the edge of one mesh disc, and a protrusion is provided on the edge of the other mesh disc. This protrusion passes through the corresponding through-hole, allowing for precise positioning of the two mesh discs. A latex ferrule or PTFE ferrule is then used to secure the mesh discs, ensuring a firm connection.
[0004] However, because the through holes and bumps are usually very small, they are inconvenient to assemble, and the ferrules are small and easy to lose, which affects the normal operation.
[0005] Therefore, improvements are needed to better meet user needs. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a drug dissolution aid device that enables rapid fixation of drug patches. This device is simple in structure, easy to use, and creates favorable conditions for improving operational efficiency.
[0007] The technical solution of this utility model is:
[0008] A drug dissolution aid includes an upper dish and a lower dish, which are identical in shape and size, both being hollow discs. The sides of the upper and lower dishes are hinged together, allowing them to open, close, and rotate around the hinge. The device also includes a fastening structure disposed on the upper and lower dishes, enabling them to be stably joined together.
[0009] Furthermore, both the upper and lower plates are disc-shaped.
[0010] Furthermore, both the upper and lower plates include an outer frame; the outer frame is annular, and a mesh-like plate is provided inside it.
[0011] Furthermore, both the outer frame and the disc are made of stainless steel.
[0012] Furthermore, there is one hinge point between the upper and lower discs.
[0013] Furthermore, the upper and lower discs are hinged together by a hinge.
[0014] Furthermore, the fastening structure includes a buckle and a slot; the buckle is disposed on the outer frame of the upper dish; the slot is disposed on the outer frame of the lower dish; the slot corresponds to the buckle, so that the buckle can be engaged in the slot.
[0015] Furthermore, the fastening structure is 180° opposite the hinge point.
[0016] The beneficial effects of this utility model are:
[0017] This utility model has a reasonable design, simple structure, and is easy to use. It can conveniently fix the drug patch, and no positioning is required during operation, which improves the operation efficiency and avoids problems such as loss of the clip, making it easy to maintain. Attached Figure Description
[0018] Figure 1 This is a schematic diagram of the structure of this utility model.
[0019] Among them, 1-upper disc; 2-lower disc; 3-clasp; 4-hinge; 5-disc plate; 6-outer frame; 7-slot. Detailed Implementation
[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0021] like Figure 1 As shown.
[0022] A drug dissolution aid device includes an upper dish 1, a lower dish 2, and a fastening structure.
[0023] The upper dish 1 and lower dish 2 are identical in shape and size, both being hollow discs, comprising an outer frame 6 and a disc plate 5. The outer frame 6 is annular, with an outer diameter of approximately 92mm, an inner diameter of approximately 86mm, and a thickness of approximately 3mm. The disc plate 5 is a mesh, disposed inside the outer frame 6, with 2x2mm square holes.
[0024] Both the outer frame 6 and the disc plate 5 are made of stainless steel, which facilitates manufacturing and maintenance.
[0025] The upper plate 1 and the lower plate 2 are hinged together by a hinge 4. There is one hinge 4, which is set on the outer frame of the upper plate and the lower plate, so that the upper plate and the lower plate can open and close around the hinge point, and the outer frames of the upper plate and the lower plate can fit together completely when they are closed.
[0026] The fastening structure includes a buckle 3 and a slot 7. The buckle 3 is disposed on the outer frame of the upper plate 1. The slot 7 is disposed on the outer frame of the lower plate 2. The slot 7 corresponds to the buckle 3, allowing the buckle 3 to be inserted into the slot 7, ensuring that the upper and lower plates will not easily separate when they are fitted together.
[0027] Preferably, the fastening structure and the hinge point are positioned at 180° to each other for ease of use.
[0028] To use, pull the clip out of the slot and flip the upper plate upwards. Then place the drug patch to be tested on the lower plate. Next, close the upper plate onto the lower plate and insert the clip into the slot to complete the assembly, effectively securing the drug patch to be tested.
[0029] This invention can conveniently fix the drug patch, and no positioning is required during operation, which improves the operation efficiency and avoids problems such as loss of the clip, making it easy to maintain.
[0030] The parts not covered in this utility model are the same as or can be implemented using existing technologies.
