In vitro diagnostic system is mainly composed of diagnostic instruments and diagnostic reagents. For the common in vitro diagnostic medical device, the core components that mainly rely on import are as follows.
1. Single Photon Counting Module
Single photon counting module is the core key component of chemiluminescent immunoassay. It is used to count the weak photons produced by chemiluminescent reagents. At present, the annual consumption in China is about 10,000 units per year.
2. Concave flat field grating
Concave flat field grating is the core key component of high-end automatic biochemistry analyzer. It is used for the generation of post-spectroscopic monochromatic light.
3. Lasers
Laser is an important key component of flow cytometer, flow particle fluorescence analyzer, digital PCR, and high-end five-classification hematology analyzer. It is used to generate a stable and narrow and fine spot light source in order to irradiate or excite the test object to form a detection signal.
4. Spiking Needle
The spiked needle is an important key component of high-end automatic biochemical analyzer and automatic chemiluminescence immunoassay analyzer. It is used to aspirate a small amount of sample (minimum 1ul) into the reaction cup. It is a key component of a series of equipment and its quality directly affects the overall performance of the instrument.
5. Plunger pump
Plunger pump is a key component of in vitro diagnostic instruments such as automatic biochemical analyzer and automatic chemiluminescent immunoassay analyzer. The plunger pump is mainly used to absorb samples and reagents.
6. Non-valve plunger pump
The valveless plunger pump is an important key component of the automatic chemiluminescence immunoassay analyzer, mainly used to pump the excitation substrate into the reaction cup. The manufacturer of valveless plunger pump is mainly IWAKI from Japan, and the price is about 2000 RMB/pc.
7. Solenoid valve
Solenoid valve is the key component of automatic biochemical analyzer, automatic chemiluminescence immunoassay analyzer and five classification hematology analyzer. Solenoid valve is mainly used for liquid flow switching and on/off, its performance directly affects the performance of the machine.
8. sheath flow cell
The sheath flow cell is a key component of the automatic five-classification hematology analyzer, flow cytometer, and flow particle fluorescence analyzer. The sheath flow cell is mainly used to generate sheath flow and detection area, and the annual demand is about 40,000~50,000.
