Description

Technical Field

[0001] This utility model relates to the field of vacuum negative pressure unit technology, specifically a medical vacuum negative pressure unit structure for use in infectious disease wards. Background Technology

[0002] Air quality in hospital infectious disease wards is often poor, with various viruses and bacteria accumulating and spreading through the air, seriously endangering the health and safety of patients and medical staff. To ensure the safety of both, a separate vacuum pump is needed in the infectious disease ward to purify the air and reduce the probability of cross-infection. Infectious disease wards differ from traditional medical vacuum equipment; they typically have around 100 beds in a tertiary hospital and require a vacuum pumping speed of 70 m / s². 3 Since there is no gas distribution cylinder in the machine room, the waste collection tank is usually installed at the lowest end of the building riser. Existing medical vacuum negative pressure units use a vacuum pump-based suction system, which lacks a buffer reserve pressure structure. It directly delivers harmful gases to the filter and purification device for filtration and purification, resulting in high operating pressure for the vacuum negative pressure unit, which can easily damage the unit. Moreover, this mode has poor purification effect. Utility Model Content
