Ventilator and Anesthesia Machine

The respiratory system is a very important life support system for the human body. The gas flow sensor, which is a key component for monitoring airflow velocity parameters, has been widely used in ventilators and plays an important role. From hospital bed oxygen supply, floor pipeline oxygen supply to oxygen generators, ventilators, anesthesia machines and other medical equipment needs the support of flow sensors.

Sensors for ventilator

A ventilator is a device that can change, control or replace human normal physiological breathing, improve respiratory function, increase pulmonary ventilation, reduce respiratory work consumption, and save heart reserve energy. It can play an important role in preventing and treating respiratory failure, reducing complications, saving and prolonging the life of patients.It has been widely used in the treatment of respiratory failure caused by various reasons, anesthesia and respiratory management during major surgery, respiratory support treatment and emergency resuscitation.

F1031V-2 micro-flow sensor

The ventilator is mainly composed of turbine, pump, valve, chip, sensor (flow sensor, humidity sensor, oxygen sensor and pressure sensor) etc. The structure is relatively simple, but the requirements are very high. Winsen Technology's fast-response micro-flow sensor F1031V-2 has been used in intensive care ventilators and portable ventilators for a long time, with stable performance and high precision.

Winsen’s oxygen sensor offering for ventilator

The oxygen pool of the ventilator, also known as the oxygen sensor, is the main component of the ventilator, which is generally located between the patient's inspiratory end and the air-oxygen mixer. The oxygen pool is only used for terminal monitoring in the ventilator. It is mainly used to measure the oxygen concentration of the mixed gas to ensure that the oxygen in line with the preset oxygen concentration is delivered to the patient. The ME2-O2 oxygen sensor is a sensor specially designed to detect oxygen concentration, the oxygen sensor has the advantages of good anti-interference, fast response and recovery, and good stability. It can avoid the possibility of oxygen poisoning caused by long-term high-concentration oxygen inhalation or life-threatening due to low oxygen concentration.

Flow sensor in anesthesia machine

sensor for Ventilator and Anesthesia Machine

Anesthesia machines are designed to deliver anesthetic to patients to relieve pain and other discomfort. Continuous anesthesia machines can continuously supply correct medical gases (such as air, oxygen, nitrous oxide) and anesthetic vapors (such as isoflurane) with accurate concentrations, and deliver these mixed gases to patients at appropriate pressure and flow rate.

The gas flow sensor can measure the flow of air, oxygen and nitrous oxide, so that the gas composition supplied to the patient is appropriate, the mixed gas delivered to the patient can be measured by the flow sensor and displayed on the screen of the anesthesia machine to meet the standards set by the doctor.

What is the Difference Between Semiconductor Sensors and Electrochemical Sensors?

There is no good linear correspondence between the gas concentration and voltage of the semiconductor sensor, and it is generally only used for fixed-point calibration products; there is a good linear correspondence between the gas concentration and the output current of the electrochemical sensor, and can be made into quantitative detection products.

What Are the Precautions for Manual Soldering of Semiconductor Sensors?

1. Flux: rosin flux with the least chlorine; 2. Constant temperature soldering iron; 3. Temperature: 250℃; 4. Time: no more than 3 seconds.

Can Wave Soldering Be Used for Semiconductor Sensors?

Yes, but you need to pay attention to the following points: 1. Use rosin flux with the least chlorine; 2. Speed: 1-2m/min; 3. Preheating temperature: 100±20℃; 4. Soldering temperature: 250±10℃;
