HaydonKerk linear stepper motors, due to their high precision, large thrust, and small space requirements, perfectly meet the design requirements of medical instruments and are widely used in the medical and laboratory automation industries, especially in medical diagnostic and laboratory analytical testing instruments. Today, we'll discuss how HaydonKerk linear stepper motors are used in these instruments .
HaydonKerk linear stepper motors are categorized into hybrid and permanent magnet linear stepper motors based on their excitation method. Hybrid motors offer higher precision and greater thrust for the same size, while permanent magnet linear stepper motors are smaller and more cost-effective. The other two types of motors are further divided into fixed-axis, through-axis, and externally driven motors based on their structure. Each type of motor has its own characteristics, allowing customers to choose the most suitable structure based on their space, structural requirements, and usage needs.
The square motors in the image below are hybrid motors, while the round ones are permanent magnet motors.
After understanding the structure and characteristics of HaydonKerk linear stepper motors, let's look at how these motors are used in medical diagnostic and testing instruments.
In vitro diagnostic (IVD) instruments, commonly known as clinical laboratory analyzers, come in many types and have diverse functions. These instruments generally test human samples, such as blood, body fluids, and tissues. By testing and verifying these samples, they obtain clinical diagnostic information, which is then used for disease prevention, diagnosis, treatment, post-treatment monitoring, and health evaluation. Based on their testing principles and diagnostic methods, these products can be further categorized into blood, biochemical, immunological, biomolecular, and tissue/cell analysis instruments. For example, in biochemical analysis instruments, chemical reactions occur between sample tissue components and specific reagents, and the instrument automatically analyzes and compares the results to arrive at the appropriate conclusions. The data from these tests is a crucial reference for doctors' judgments, making laboratory instruments a vital diagnostic tool in modern medicine.
Because testing requires liquid chemical reactions, precise sample and reagent movement and quantitative sample addition are two crucial steps, involving two linear movements: sample movement and reagent addition. Both movements have high positioning requirements, especially reagent addition. Since addition accuracy directly affects diagnostic results, and these movements must be completed within a compact instrument, the transmission components must be as small as possible while maintaining precise positioning. HaydonKerk linear stepper motors perfectly meet these requirements, hence their widespread use and excellent performance in laboratory instruments.
The image below shows an example of the application of Haydon Kerk hybrid motors in a biochemical analyzer.
In addition, with the outbreak of the COVID-19 pandemic, many medical instrument companies at home and abroad have launched COVID-19 nucleic acid testing instruments to combat the epidemic. HaydonKerk 's linear stepper motors have performed outstandingly in these instruments and are the core transmission components of these instruments, ensuring accurate analysis of the disease.
The image below shows the application of the HaydonKerk G4-19000 motor in a COVID-19 nucleic acid testing instrument developed by the Finnish company Mobidiag.
In summary, HaydonKerk linear stepper motors enjoy a high reputation and wide application in the fields of medical diagnostics and laboratory analytical instruments, making them the preferred linear drive partner for instrument manufacturers worldwide! HaydonKerk is also continuously developing new products to provide customers with better products and services!
