Description

Wheelchair supporting device capable of being laid down and convenient for rescuing patients instantly and wheelchair

Technical Field

The utility model relates to the field of wheelchairs, in particular to a reclining wheelchair supporting device and a wheelchair, which are convenient for rescuing patients immediately.

Background

The wheelchair belongs to common tools in hospitals, and along with development, more and more multifunctional wheelchairs are produced according to the requirements of patients. For example, a flat wheelchair can be laid flat by mechanical or electric driving, and the patient can rest in other postures besides sedentary.

There are many wheelchairs with a flat function, for example, the utility model with publication number CN208447968U discloses a flat lying structure, which realizes the function of flat backrest of a simple wheelchair, and realizes the structure of a wheelchair with flat backrest of an electric drive chair through a complex mechanical structure.

In the actual medical work, a plurality of patients using the wheelchair are easy to have the onset of emergency in hospital and need to be rescued immediately, for the patients who are inconvenient or not suitable for carrying, if the wheelchair can be directly rescued, the wheelchair can strive for the gold rescue time, improve the rescue rate, for example, the utility model disclosed in CN109077863A discloses a wheelchair with medical emergency function, when the emergency occurs to the patient, the worker can draw out the tightening shaft relative to the middle part of the second conversion shaft, the bottom end of the backrest is separated relative to the body to rotate the backrest relative to the body, so that the backrest forms the same horizontal state relative to the body, the same adjusting inclined rod is in the horizontal state relative to the body, the unloaded tightening shaft is inserted into the tightening groove, the inclined rod is in a fixed horizontal state relative to the body, so that the wheelchair is constructed into a bed body structure.

However, the wheelchair has serious design defects that after the wheelchair is laid flat, the seat of the wheelchair bears the buttocks and the legs of a patient, the backrest of the wheelchair bears the trunk and the head, the center of gravity of the patient is inclined backward, the supporting wheels of the wheelchair are centered, the patient can easily tip backward after lying flat, when rescue is carried out, first-aid means such as chest pressing are inevitably needed, so that the unstable center of gravity is inclined backward, and the wheelchair can be rescued on the spot by supporting the backrest by a specially-assigned person or a specific supporter.

Of course, in order to adjust the center of gravity of the wheelchair, the wheelchair is also provided with a seat which can be adjusted forwards and backwards, such as disclosed in CN203354789U, so that the distance between the front and the back of the wheelchair is wide and the wheelchair is not flexible enough, and meanwhile, the adjusting mechanism is complex and time-consuming and labor-consuming to adjust, and the emergency treatment is also affected when the patient is not matched in emergency.
