Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a negative pressure isolation cover for a wheelchair. Background Art
[0002] Wheelchairs are important tools for rehabilitation. They are not only a means of transportation for people with limb disabilities and mobility difficulties, but more importantly, they enable them to exercise and participate in social activities with the help of wheelchairs. Since wheelchairs are often used to transport some infectious patients who can spread through aerosol contact, fecal-oral contact and other routes, it is inconvenient for patients to put on and take off isolation clothing. However, existing wheelchairs do not have an isolation cover to isolate external sources of infection, which is inconvenient to take protective measures and the user experience is not good. At the same time, the internal support structure of the negative pressure isolation device is mainly divided into the following two categories: one is a tent pole structure, which has the advantages of light weight and can be folded; the disadvantages are too many accessories, complicated operation and poor stability. The second is a plate support structure, the materials include plastic, aluminum alloy and stainless steel, etc., the advantages are high negative pressure resistance, the cabin is not easy to deform, and the dimensional stability is good; the disadvantages are that it is generally not foldable, heavy, and inconvenient to store and transport. Therefore, in order to avoid the shortcomings of the prior art, it is necessary to improve the prior art. Utility Model Content
