Introduction to the application and function of magnets in medical sensors

 

We are all very familiar with magnets, which are widely used in various fields of our lives. Many products will be useful. Today I will tell you about the application of magnets in medical sensors. What is the main function?

1. It is applied to the force sensor of the infusion pump to ensure that the pipelines of the infusion pump and the insulin pump that deliver the medicinal solution to the patient are unimpeded.

 

2. Gas flow sensors for gas chromatographs, medical chromatographs need to accurately monitor and regulate the flow of gas. The precision and reliability of the chromatograph is enhanced because the ceramic gas flow lines in the sensor prevent outgassing.

 

3. Sensors used in hospital diagnostic equipment, such as airflow sensors to regulate the airflow velocity of gas chromatographs, touch force and position sensors to control laboratory automatic robots.

 

4. The thermistor element temperature sensor used in the blood analyzer is used to monitor the temperature of the compartment, diffusion lamp and oil-cooled motor to avoid overheating. If overheating occurs, stop the machine immediately to cool it down.

 

5. The gas flow sensor used in the anesthesia machine can measure the flow of air, oxygen and nitrous oxide, so that the composition of the gas supplied to the patient is appropriate and meets the standards set by the doctor. The thermistor element temperature sensor monitors the temperature/humidity of the air sent by the anesthesia machine, which can make the patient breathe comfortably and avoid sore throat caused by inhaling dry and cold air.

 

6. Sensors used for monitoring instruments, pressure sensors, and gas flow sensors can be used for respiratory monitoring, and special-shaped magnet manufacturers display key indicators related to breathing. Insertable pressure sensors are used for blood pressure monitoring and glucose monitoring.

 

7. The airflow sensor applied to the sleep apnea machine, when the patient starts to exhale, the sensor sends a signal to inform the sleep apnea machine to reduce the speed of the ventilator fan, so as to prevent the patient from feeling uncomfortable in the confrontation with the machine. The humidity sensor is used to Monitor the humidity of the air, accurately measure its dew point and absolute humidity or water content, in order to supply the patient with air of appropriate humidity.

 

8. Infrared sensor for blood cell analyzer. When the infrared sensor is used for blood cell analyzer, it can be combined with the encoder on the pump shaft to calculate the number of rotations of the pump shaft. When opaque objects pass through the packaging gap to block the passage of infrared rays , the sensor can detect it.

 

9. Humidity sensors used in medical ventilators help to deliver warm and humid air and make patients feel comfortable. When moisture is introduced into the airflow, it should be monitored and controlled.

The above is an introduction to the application and function of magnets in medical sensors. In addition to medical sensors, there are many sensors that use magnets.
