What is a ventilator bacterial filter?

The ventilator bacterial filter is a simple filtration structure, low cost, high stability, and simple operation. Use discarded types for later use without the need for equipment maintenance and replacement. The filter membrane of a bacterial filter usually selects an imported effective filtering medium, which can effectively remove residues, bacteria, and other pathogenic bacteria in the flow pipeline. Usually, the filtering rate of 0.5m in the air exceeds 90. Patients are infected with each other caused by the main bacteria of various diseases. So what is a ventilator bacterial filter?

What is a ventilator bacterial filter?

The types of ventilator bacterial filters can be divided into a time recyclable bacterial filter:

1. The expiration date for using the sex bacteria filter is 6 minutes, and it should be discarded after use.

2. The cable can be used for bacterial filters. After use, sterilize with high-pressure and high-temperature steam. The usual pressure is 2.2kPa, the ambient temperature is 135C, and the time period is 7 minutes. It can achieve sterilization effect.

What is the difference between a ventilator bacterial filter and an artificial nose filter?

1. There are significant differences in mechanism and clinical medicine: Artificial nose filter heat exchange (HME), commonly referred to as an artificial nose, is a passive humidification device. This mechanism utilizes the combination of the patient's environmental temperature and humidity with chemical water and heat storage functions to exhale in gas, thereby reducing hydrogenation in the respiratory tract and moderate heating of inhaled gas. Specifically targeting patients with short-term airway temperature and humidity, for emergency, anesthesia, and ICU short-term mechanical ventilation patients.

Although the appearance of the two is similar for clinical medical work, everyone can distinguish the name from the external packaging box; If it is no different from the packaging box, then everyone can construct from its features. Lithium chloride sponge structure, while bacterial filters have filter membranes.

What are the preventive measures for using a respirator bacterial filter?

Currently, the mainstream of bacterial filters is low resistance bacteria/virus filters. It effectively solves the problem of gas delivery resistance caused by improving filters. Therefore, bacterial/viral filters.

However, in clinical practice, due to nebulization caused by ventilators, airway temperature, and humidity, water filters may accumulate, leading to resistance to mechanical ventilation and affecting the patient's proper ventilation. When this situation occurs, the bacterial filter should be replaced immediately to prevent accidents.

What is a ventilator bacterial filter? Regarding the relevant knowledge, the use of bacterial filters in ventilators is still quite widespread. I hope it can help you!
