DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The present invention is with respect to a stretcher with an adjustable belt designed for use as a safety belt for a patient using the stretcher.
On transporting persons on stretchers in an ambulance, there is a chance, from time to time, of the ambulance being voilently slowed down, as for example on smashing up against something in its way in a road accident. For stopping injuries to the patient in such a case, there has been a suggestion (see German Pat. No. 2,543,473) to have a belt sloping over one shoulder of the patient and fixed to the head end of the stretcher so that the patient's shoulder is kept at least 20 cm from the head end. This distance of 20 cm is in fact a lower limit for the distance between the patient's shoulder and the head end. On an ambulance (transporting a stretcher on which a patient is safety belted by using such a sloping shoulder belt) crashing up against something in its way, the patient will firstly be forced forwards through this distance of about 20 cm before being stopped by the safety belt; it may then be that his or her head will be even pushed over and past the head end of the stretcher so that it will no longer be supported.
For getting round such shortcomings, I have, in the past, designed a system in which the safety belt was to be fixed at shoulder level, this, however, limiting the width of the stretcher for supporting the patient; furthermore it seemed likely that, if the stretcher was, in effect, made narrower for the patient, there would be a greater chance of patient injury. It would furthermore have been possible for the safety belt to have been trained round under the stretcher, that is to say not at its head end, for which purpose, however, the safety belt would have to have been threaded through holes in the cover sheet on the stretcher and the support thereunder. Because, however, the support is to be able to be taken off again, it would seem to be a waste of time and unnecessarily complex for the safety belt to have to be threaded through the cover sheet and into the support every time the stretcher is used. Furthermore, the support and the cover of the stretcher would have to have special holes for this.
GENERAL OUTLINE OF THE INVENTION
For this reason, the purpose of the invention is that of designing a stretcher of the sort noted, in the case of which there is no chance of injury to the patient even when there is a sudden, sharp motion of the stretcher in the length direction. For effecting this purpose, the safety belt is united with a backup cushion on which the patient is so rested that, even on sudden forces acting in the length-direction of the stretcher, the patient is kept in position on the stretcher.
In the case of the invention it is, in fact, possible to say that the safety belt is united with a backup or stop cushion to make up inertia forces when the ambulance is violently slowed down or speeded up.
More specially, it is possible for the backup cushion to be designed so that the shoulders of the patient are supported on it on a backup face, the cushion being inwardly curved for the head and neck of the patient.
As a further useful development of the invention, the stretcher has a further safety belt, which, like the first-noted safety belt, is run over one shoulder in each case of the patient. The safety belt and the further safety belt are, in this case, each fixed at one end on the backup cushion while the other ends of the two belts are fixed to said rails of the stretcher at its head end. The other end of the two safety belts may, in this respect, be fixed on the side rails at the same level as a fixing belt, running across the stretcher. It is furthermore possible for the first safety belt and the further safety belt noted to be joined to the fixing belt itself.
A useful effect may furthermore be produced if at least one belt is used for fixing the backup cushion on the stretcher. This belt, and possibly a further belt, will, in this case, be able to be fixed on one side rail or bar of the head end o
