Description

A purification type negative ion bed Technical Field

[0001] The present invention relates to the technical field of hospital beds, in particular to a purification-type negative ion hospital bed. Background Art

[0002] In recent years, outbreaks of influenza viruses such as the new coronavirus and influenza A have continued, and hospitals across the country are in urgent need of prevention and control supplies, especially hospital beds.

[0003] Ordinary hospital beds cannot prevent viral infection, and wards with air circulation purification are too expensive. Therefore, in wards for patients with infectious diseases, cross-infection is likely to occur between patients and between patients and medical staff. Simply placing air purification equipment has a general purification effect and can only purify a part of the air purification equipment. It cannot effectively purify the air exhaled by the patient on the bed. Therefore, we propose a purification-type negative ion hospital bed.
