Description

Stretcher is transported in pre-hospital first aid that multi-scene used

Technical Field

The utility model relates to a first aid transfer apparatus technical field, concretely relates to stretcher is transported in pre-hospital first aid that many scenes used.

Background

The first-aid transfer stretcher is common equipment for outgoing first-aid, and plays an important role in quickly transferring wounded persons, ensuring that the wounded persons are treated as soon as possible and are separated from dangerous cases. With the development of modern urbanization, high-rise buildings in China are increasing year by year, but old houses and houses below six floors are not provided with elevators, the stretcher vehicles used in hospitals generally adopt a flat push type or a manual lifting type, the former can not climb the building, the latter needs more rescuers to carry together, and the common soft manual lifting stretcher is light in structure, but is inconvenient to transport patients with large body weight and large body shape, is very inconvenient particularly in the scene of the visit of female doctors and nurses, has transportation cost and potential safety hazards of easy rollover, and even influences the rescue work. In addition, in the rescue scene with an elevator, the situation that the space of the elevator is narrow often occurs, and the transfer stretcher cannot be used. The existing solution is that a wheelchair is firstly used for transporting a patient in a high-rise building with an elevator, the patient is replaced by a stretcher when transported to the flat ground, and sudden diseases in the transportation process cannot be timely used by equipment for cardio-pulmonary resuscitation. The wheelchair needs to be additionally carried when the ambulance goes out of the ambulance for emergency, but the wheelchair is integrally large, not only occupies the space of the ambulance in a squeezing mode, but also has secondary injury risk in multiple transportation.

CN204072514U discloses a stretcher suitable for elevator, which comprises a stretcher base, a stretcher base pin shaft, a stretcher body, a safety belt, a hydraulic system and casters, when in use, the length of the whole pair of stretchers can be changed by rotating the stretcher body by a certain angle, although the technical scheme can make the stretcher enter into a common residential elevator, the stretcher is still inconvenient to be applied to a high-rise residential building which is not equipped with an elevator because the stretcher is inconvenient to climb the building. CN209899798U discloses a novel stair stretcher, which comprises a crawler beam assembly, a balance mechanism and a stretcher bed, wherein the crawler beam assembly comprises two crawler beams and a connecting rod; a balance mechanism is arranged on the connecting rod, the balance mechanism comprises two supporting rods, two bearings, a rotating shaft and a first rotating motor, one end of each of the two supporting rods is connected with the bearing, the rotating shaft is arranged on the two bearings, and the rotating shaft is connected with the first rotating motor; the rotating shaft is also connected with a stretcher bed, the surface of the stretcher bed is arranged upwards, and the stretcher bed rotates relative to the two crawler beams through the rotating shaft; be equipped with the balancing pole on the stretcher bed, the middle part is equipped with the balancing tank in the balancing pole, be equipped with the roll ball in the balancing tank, the roll ball is located the balancing tank when stretcher bed and two track beam place faces are parallel, otherwise roll out the balancing tank outside with the contact of balancing pole tip, all be equipped with contact pick-up on the tip of both ends in the balancing pole, contact pick-up and first rotating electrical machines all are connected with the controller, this technical scheme can keep patient's level to lie when using in stair, can avoid the patient landing in handling, because it can't be folded, inconvenient be applied to in the comparatively narrow and small staircase in space or elevator room. Therefore, the prior art solution still has the defect that the use scenario is limited.
