Thermal Solutions for Hematology Analyzers
Introduction of blood cell analyzer:
Blood cell analyzer is also called blood cell analyzer, blood cell analyzer, blood cell analyzer, blood cell counter, etc.
Blood cell analyzer is an instrument widely used in clinical testing. Blood testing refers to routine blood examination. It was first counted by manual operation and under microscope. It includes red blood cell, hemoglobin, white blood cell count and its classification, platelet count, etc.
Basic structure of blood cell analyzer:
The basic structure of blood cell analyzer is mainly composed of mechanical system, electrical system and optical system.
Computer system
The mechanical system includes mechanical devices (such as sampling needle assemblies, syringe assemblies, mixers, blood separators, volumetric tubes, etc.) and vacuum pumps to complete the aspiration, dilution, transfer, mixing and transfer of samples into corresponding assays At the same time, the liquid system is the core part of the mechanical system, which mainly includes the sensor part, the colorimetric cell part, the hemolyzing agent adding and mixing part, the dilution part, the volume measurement part, the vacuum part, the pressure part and the auxiliary part.
Electrical system
The electrical system consists of main power supply, main control board, various circuit control boards (power driver board, analog amplifier board, key board, recorder driver board, volume measurement board, switching power supply board, power indicator board, etc.), temperature control system , display, monitoring and alarm system.
Optical system
The optical system is mainly composed of a blood cell detection system and a hemoglobin detection system. There are two main types of blood cell detection systems: electrical impedance detection technology and light scattering detection technology. The electrical impedance detection technology system consists of detector, amplifier, discriminator, threshold regulator, detection counting system and automatic compensation device; the flow light scattering detection technology system consists of laser light source, detection device and detector, amplifier, discriminator, threshold value It consists of regulator, detection and counting system and automatic compensation device. The hemoglobin detection system consists of light source, lens, filter, flow cell and photoelectric sensor.
Glue requirements for blood cell analyzers:
- High bonding strength to the chassis frame;
- Excellent heat dissipation for heating components;
- Environmental protection, non-toxic, with routine testing certification and qualifications;
- Moisture-proof, anti-static, dust-proof, mildew-proof, salt-fog resistance, etc. for circuit boards.
Glue scheme for blood cell analyzer:
| Glue location for blood cell analyzer | Glue function category | Adhesive glue features |
| Cooling components | Thermal grease thermal paste | Excellent thermal conductivity, good insulation effect, moisture-proof, dust-proof, anti-corrosion, shock-proof and other properties |
| relay | Potting compound | Potting protection, insulation, moisture-proof, shock-proof, dust-proof, anti-corrosion, anti-aging |
| Plastic vs Metal (Case) | adhesive sealant | Good adhesion, good sealing effect, high and low temperature resistance, good resistance to stress changes |
| Electronic Components | fixing glue | Strong adhesion and fixation to electronic components, excellent dielectric properties and good heat resistance |
| circuit board | Three-proof glue | Good protective performance, with moisture-proof, anti-static, dust-proof, anti-mold, salt spray resistance and other properties |
Medical devices are related to human health, and hospitals are also the most likely places for viruses to spread, so the use of medical devices is more rigorous. Therefore, in addition to complying with a series of hospital use regulations, many medical devices are resistant to sterilization and low toxicity.
Adhesives used in medical devices need to be tested for effects on viruses, cells, blood and other systems. Because these medical devices or the adhesives used to assemble medical devices can come into contact with the patient’s exposed skin, system tissues, etc. at any time, it is necessary to be more careful.
