Application of integrated brushless motor in automatic sampling transdermal diffusion system

 

In the field of drug development and cosmetic testing, the application of transdermal diffusion systems is critical. The automated sampling transdermal diffusion system provides researchers with an accurate and efficient means of testing by simulating the penetration process of drugs or cosmetics on the skin.

With the advancement of technology, the integrated brushless motor has been widely used in the automatic sampling transdermal diffusion system because of its advantages of high efficiency, low noise and long life.

01. Equipment Introduction

Automatic sampling transdermal diffusion system is a device used to simulate the penetration process of drugs or cosmetics on the skin. The system achieves accurate measurement of drug or cosmetic transdermal release through the functions of high precision sampling, heating, stirring and exhaust bubble.

A

system usually consists of the following parts:

A customer's automatic sampling transdermal diffusion system

Diffusion cell:

For the placement of skin samples and pharmaceutical preparations to simulate a transdermal absorption environment.

Sampling device:

Automatic sampling by sampling needle and collection of sample solution.

Heating stirring device:

Keep the temperature in the diffusion cell constant, and promote the uniform distribution of the drug in the medium by stirring.

Control system:

is used to control the operation of the entire system, including sampling, heating, mixing and other processes.

The integrated brushless motor is a highly integrated servo "system" that integrates a brushless motor, encoder and driver. Compared with the traditional distributed brushless motor, the integrated brushless motor is greatly reduced in size and reduces the connection of cables, making the entire servo system more compact and easy to install into the equipment, especially those with limited internal space. At the same time, the encoder built into the motor monitors the rotation Angle of the motor in real time to ensure that the desired position is reached and maintained.

Using the Integrated brushless motor in the automatic sampling transdermal diffusion system can make the whole system more compact and integrated. At the same time, the high efficiency, low noise, high precision and other characteristics of the integrated brushless motor ensure the accuracy and reliability of the sampling, heating, stirring and other processes, making the operation of the automatic sampling transdermal diffusion system more stable and efficient.

02. Solution Example

In the automatic sampling transdermic diffusion system, the integrated brushless motor is used to drive the rotation of the "sampling device", so that the sampling needle reaches the "vertical" or "inclined" state, and then realizes the functions of automatic cleaning, automatic sampling, automatic sample collection, automatic media recovery.
