Description

technical field

[0001] The invention relates to the technical field of circulation ventilation devices, in particular to an aseptic circulation ventilation device and a circulation ventilation method for intensive care units. Background technique

[0002] After the patient undergoes surgery, the patient usually needs to stay in the ICU ward for a period of time, and gradually wake up and recover under the care of medical machines and related professional medical staff. During this period, the patient in the ward usually has poor self-management ability and weak resistance. Poor, the environmental requirements of the ward are more stringent than those of the general ward, so it is necessary to carry out ventilation cycle purification treatment for the ICU ward, so as to improve the quality of medical care and reduce or eliminate postoperative infection.

[0003] The defective that existing circulating ventilation device exists is:

[0004] 1. The comparative document CN20986...
