Embodiment Construction

[0015] Such as Figure 1 to Figure 3 As shown, the transdermal diffusion cell electromagnetic stirrer provided by the present invention includes an electromagnetic coil and an electromagnetic stirring driver circuit connected with the electromagnetic coil. The electromagnetic coil includes a shell 3 from which two coil pins 2 are drawn. ”-shaped hollow coil bobbin 4, coil 5 is wound on the hollow coil bobbin 4, a soft iron core 6 is arranged inside the hollow coil bobbin 4, soft iron sheets 7 are stamped at both ends of the soft iron core 6, and two ends of the coil 5 are connected with two coil pins 2 connections. The air-core coil bobbin is cylindrical with a hollow center and square sides. The air-core coil bobbin is covered with 0.06 mm enameled wire to make the coil resistance reach 700Ω. A soft iron core with a diameter of 3 mm is placed in the hollow of the hollow coil skeleton, and the two ends of the soft iron core are 1 mm long and 2.5 mm in diameter, and then stamp...

Abstract

The invention discloses an electromagnetic stirrer of a transdermal diffusion cell. According to the electromagnetic stirrer, a direct-current motor is not used any longer and the problems of large volume, high noise and short life of the traditional magnetic stirrers are overcome; by applying positive and negative alternating voltage on a coil through a driving circuit, an electromagnetic field with magnetism alternating 180 DEG between N and S is generated between soft iron sheets at two ends of a soft iron core; the electromagnetic stirrer consists of an electromagnetic coil and an electromagnetic stirring driver circuit; the electromagnetic coil comprises a shell which is provided with coil pins at the lower part; an I-shaped hollow coil framework is arranged in the shell; a coil is arranged on the hollow coil framework; the soft iron core is arranged in the hollow coil framework; the soft iron sheets are respectively arranged between two ends of the soft iron sheet and two ends of the hollow coil framework; and coils are arranged on the coil pins. The electromagnetic stirrer of the transdermal diffusion cell has the characteristics of being simple in structure, small in volume, free of noise, low in power consumption, durable, good in stirring effect and suitable for the transdermal vertical diffusion cells and horizontal diffusion cells in any heating manner.

Description

technical field [0001] The invention belongs to the technical field of in vitro transdermal diffusion test equipment for transdermal drug preparations, in particular to an electromagnetic stirrer for a transdermal diffusion cell applied to a vertical diffusion cell and a horizontal diffusion cell. Background technique [0002] At present, the main method used in the in vitro transdermal diffusion test of transdermal preparations is the diffusion cell method. This method can reflect the speed and degree of drug penetration through the skin of living animals, and can screen the prescription of transdermal drug preparations. It is currently an internationally recognized standard detection method for drug transdermal absorption tests. [0003] There are two main types of diffusion cells currently used in in vitro transdermal diffusion tests, the improved Franz diffusion cell (vertical diffusion cell) and the Valia-Chien double-chamber diffusion cell (horizontal diffusion cell). ...
