Description
DEVICE FOR THE ASSISTED LOADING OF A STRETCHER
TECHNICAL FIELD
The present invention relates to the technical field of the medical devices used for transporting patients and it refers to a device for the assisted loading of a stretcher particularly suitable to facilitate the insertion and the loading of the stretcher in an ambulance or the like.
BACKGROUND ART
There are known ambulance stretchers equipped with pivoting legs folded in a direction parallel to the stretcher positioned inside of the ambulance and that, when coming out from this ambulance, they rotate about 900 disposing themselves vertically in order to support the plane of the stretcher.
An end of each leg has a wheel for the movement of the stretcher out of the ambulance.
When the stretcher is loaded with the patient in the space of the ambulance, the legs contact a counterpart of the ambulance and they are refolded.
A drawback of said known stretchers consists in that when loading in the ambulance, the operators need to use a considerable effort to provide the necessary energy for loading the heavy stretcher with the patient and to refold the legs.
Other drawback consists in that the impact between the legs and the counterpart of the ambulance, due to the eventual small run-up made by the operator, can be violent and thus irritating, painful and harmful for the patient particularly for the traumatized patient.
Document EP0972505A2 discloses a fitting for facilitating the loading of a stretcher onto a platform. The fitting includes a pivotable mounting having a trailing larger diameter wheel and a leading smaller diameter wheel.
DISCLOSURE OF THE INVENTION
An object of the present invention is to propose a device for the assisted loading of a stretcher, being able to reduce or avoid the effort of the operator when loading and/or unloading the stretcher with the patient.
Other object is to propose a device that allows to reduce the impact between the legs of the stretcher and the ambulance in order to increase the comfort and the safety for the patient.
The above mentioned objects can be obtained in accordance with the content of the claims.
