In practice, in addition to the ambulance bed, the transfer bed, the stretcher bed, the emergency bed, etc. can all be used to transport patients, transferring patients from outside the hospital to the hospital, or transferring patients within the hospital.

[0003] The transport devices such as ambulance beds or stretcher beds in ambulances are mainly responsible for the transportation of outdoor patients. When the weather is hot or rainy, patients need to be shielded to prevent them from sunburn or getting wet in the rain, which would aggravate their condition. However, transport devices such as ambulance beds do not have rainproof structures. Generally, rainproof cloth is directly used to cover the patient, or medical staff follow with umbrellas to shelter the patient from the rain. However, the above-mentioned rainproof method is not only troublesome, but also has poor protection effect. Patients are still easily wet, which affects the treatment of their condition. At the same time, the above-mentioned rainproof method does not take medical staff into consideration, and being wet in the rain for a long time is also a harm to medical staff.

[0004] The existing patent number CN208710296U is a medical flatbed with a sunshade or rain shelter, which includes two front and rear support frames, support rods, U-shaped grooves, scaffolds, tarpaulins, curved baffles, etc. The device protects medical staff and patients at the same time through detachable scaffolds and curved baffles. However, the overall size of the device is large, and in actual use, it takes a lot of time to install or disassemble, which is inconvenient to use. Utility Model Content
