Sterile circulating ventilation device for intensive care unit and circulating ventilation method

Abstract

The invention discloses a sterile circulating ventilation device for an intensive care unit and a circulating ventilation method. The sterile circulating ventilation device comprises a connecting base and a disinfection filtering net plate, wherein a driving motor is arranged at the top of the connecting base; embedded sliding blocks are arranged on the surface of a first reciprocating lead screw and the surface of a second reciprocating lead screw; a supporting bottom plate is arranged at the tops of the embedded sliding blocks; a suction windbox and a mounting chamber are arranged at the top of the supporting bottom plate; an air supply pipe is arranged in the mounting chamber; a branch pipe is arranged on the side surface of the air supply pipe; a T-shaped alarm valve cock is arranged at the top of the branch pipe; one end of the air supply pipe is connected to a preparation branch pipe; and a push-pull cylinder is arranged on the top surface of the side, away from the driving motor, of the connecting base. By arranging the alarm valve cock, when an exhaust air duct of the device is blocked, warning light and warning buzzing can be given out in time, medical workers are reminded of coming to maintain the device, and it is guaranteed that ventilation cycle work of the device is normally conducted.

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...

AI Technical Summary

Problems solved by technology

The indoor air disinfection device for the ICU intensive care unit can initially sterilize the indoor air through the setting of the air disinfection layer and the first ultraviolet disinfection lamp. Under the excitation of the second ultraviolet disinfection lamp, the catalyst material mainly composed of nano-titanium oxide can catalyze and decompose the chemical pollutants in the air, so as to further disinfect and sterilize the indoor air, making the air disinfection in the intensive care room more thorough , to avoid secondary pollution caused by air flow", but the device is fixed installation, the effective area of ​​the ventilation cycle is limited, and the moving distance of the ventilation cycle cannot be adjusted, which is inconvenient to use
