Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a ventilator system and a ventilator. Background Art

[0002] In modern clinical medicine, ventilators, as an effective means of artificially replacing spontaneous ventilation function, have been widely used in respiratory failure caused by various reasons, anesthesia respiratory management during major surgery, respiratory support therapy and emergency resuscitation, and occupy a very important position in the field of modern medicine.

[0003] However, the traditional ventilator has a relatively monotonous way of processing air. Some traditional ventilators may directly introduce air for oxygen production or atomization treatment. If the surrounding air quality is poor, it will affect the treatment effect; another part of the traditional ventilator may filter or disinfect the introduced air, while the surrounding air quality may be very high and can be used directly. In fact, there is no need to filter or disinfect and consume too much energy, which will objectively accelerate the aging of the ventilator. Therefore, it is necessary to provide a ventilator that can judge the air quality and selectively process the introduced air.

In addition, it should be emphasized that if the surrounding air quality is low, the air can be re-discharged into the outside atmosphere from the purified air path after being disinfected by the disinfection module of the second air inlet path to improve the surrounding air environment.
