[Technology] TDK-Lambda in vitro diagnostic equipment power supply system overall solution

As an in vitro diagnostic instrument based on the important hardware of the IVD industry, its iterative upgrade speed is also accelerating, and it continues to put higher demands on its testing speed, accuracy and stability. TDK-Lambda combines its low-noise, high-reliability products with local technical service offerings to provide a total solution for the power subsystems within the core of IVD instruments.

1 Overview:

Clinical diagnosis is an important means to confirm the etiology in modern medicine. It is mainly divided into in vitro diagnosis and in vivo diagnosis. At present, more than 80% of clinical diagnosis of diseases depends on in vitro diagnosis. Generalized in vitro diagnosis refers to products and services that obtain diagnostic information by detecting biological samples (blood, body fluids, tissues, etc.) of the human body outside the human body. The narrow in vitro diagnostic industry mainly refers to in vitro diagnostic related products, including in vitro diagnostic reagents and in vitro diagnostic equipment.

2. Classification of in vitro diagnostic instruments:

The basic principle of in vitro diagnosis is to use the reagent and biological sample to carry out biochemical reaction in vitro. According to the corresponding in vitro diagnostic instrument, the intensity of biochemical reaction between the reagent and the biological sample is determined in vitro, and then the nature and quantity index of the biological sample are inferred, and the index is The normal physiological state interval values ​​are compared to determine the physiological state of the human body. Although different in vitro diagnostic methods have the same basic principles, their specific testing principles have significant differences.

According to different test principles, in vitro diagnosis includes biochemical diagnosis, immunodiagnosis, molecular biological diagnosis, hematological diagnosis, microbial diagnosis, urine diagnosis, blood coagulation diagnosis and the like. The corresponding in vitro diagnostic instruments mainly include biochemical analyzer, chemiluminescence immunoassay analyzer, real-time fluorescence quantitative PCR instrument, blood analyzer, microplate reader, flow cytometer and the like.

In vitro diagnostics can be divided into central laboratory and point-of-area testing (POCT) depending on the application site. Central laboratory applications include hospital laboratory and third-party laboratories (ICL), while immediate testing (POCT) applications include hospital operating rooms, ICU wards, emergency rooms, clinics, nursing homes, and homes. Instant detection differs greatly from central laboratory applications in terms of immediacy and ease of operation and compatibility of reagents with analytical instruments.

At present, biochemical diagnosis, immunodiagnosis and molecular biology diagnosis in the domestic market are the three major areas of clinical in vitro diagnosis.

3. Typical architecture of in vitro diagnostic equipment:

In vitro diagnostic instruments typically have built-in complex detection systems, including sample flow control subsystems, optical detection subsystems, environmental control subsystems, automatic control and signal processing subsystems, power supply subsystems, and user graphical interface (GUI) subsystems. Wait.

Although the overall internal architecture of the instrument is similar, there are some differences in the internal system architecture of different in vitro diagnostic instruments because of the differences in the specific testing principles of various in vitro diagnostic techniques.

The figure above shows the internal system block diagram of a typical biochemical analyzer, including subsystems such as biochemical detection, sample flow control, temperature control, signal processing, power supply, and GUI. The biochemical detection system includes a spectrophotometer and an electrochemical module. The sample flow control system includes sample collection and movement, reagent flow control, sample cup and line cleaning. The temperature control system provides a biochemical reaction environment for simulating human body temperature for samples and reagents. The signal processing system provides multi-channel data analysis processing by the DSP on the motherboard. The power supply system includes an AC/DC filter, an off-line switching power supply (AC-DC), and a DC switching power supply (DC-DC).

The chemiluminescence immunoassay analyzer includes a sample subsystem, a incubation subsystem, a centrifugal cleaning subsystem, an optical detection subsystem, a user interface subsystem, a signal processing subsystem, a power subsystem, and the like.

The real-time fluorescence quantitative PCR instrument includes a basic PCR part consisting of heating wire, temperature acquisition and temperature treatment, and a fluorescence detection part consisting of an excitation light source, a photomultiplier tube, and signal acquisition and processing, and is composed of data acquisition and system analysis software. The upper computer part, the power supply system, etc.

Industrial Laser Distance Sensor
