BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a scoop litter for the transporting an injured person. There are principally two types of litters and namely rigid, possibly folding litters, to use in which, the injured person must be lifted up and placed on the litter. In the second type, the so-called "scoop litter" which is divided along its longitudinal axis, the longitudinal braces are equipped with support elements, which can be pushed under the injured person like a series of scoops, without the person having to be lifted in order to perform this action. Such scoop litters are extremely useful in cases where the injured person has suffered a spinal injury. In these cases, incorrect lifting can be extremely dangerous to the injured person. This is true not only for transport from the scene of the accident to the hospital, but also during treatment at the hospital itself. This is because at the hospital, an x-ray is first taken, in order to determine the nature and extent of the injury. A first observation generally takes place while the injured person is still lying on the litter on which the patient was brought to the hospital. Present designs of scoop litters only permit this to a limited extent. X-rays can only be taken vertically to the support surface of the litter. X-rays cannot be taken from the sides since the metallic parts, and in particular the braces of the litter, are made of metal. An X-ray picture taken from the side is often insufficient to determine the exact location of the injury.
If an X-ray must be taken from the side, the patient must be lifted off the litter on which he was brought into the hospital, which under certain circumstances, can be dangerous to the patient.
SUMMARY OF THE INVENTION
Therefore, it is one object of the invention to provide a scoop litter which will permit both vertical and side X-rays to be taken. This represents a great improvement for the patient, for the personnel and for the radiologist and also reduces the risk to the patient. It is a necessity to take X-rays of a person lying on a litter. Thus, for example EU-A-0110 851 describes a litter to which support elements made of plastic can be retrofitted for this purpose. Nonetheless, even with the retrofit such litter does not fulfill the above-mentioned requirements, because it does not permit X-rays to be taken from the side. In addition, this litter is designed solely for use within the hospital and is not a litter which permits the conveyance from the scene of the accident to the hospital which permits a subsequent X-rays examination at the hospital without the patient having to be lifted from the litter. The manufacture of a litter which permits X-rays to be taken from the side of the patient lying upon it has only become possible through the use of recently developed materials for the braces.
The connection of the bearing elements to the braces, especially where these are intended to pivot, also presents certain difficulties because of occurring high local loads.
The invention solves the above object of this invention with the litter having a rectangular, tubular frame which can be divided along its longitudinal axis. The length and width of the tubular frame are dimensioned to accommodate the form of a human. At least the middle portion of the longitudinal braces of the frame and the attached support elements are constructed only of non-metallic material which allows the passage of X-rays to permit radiological examination from all sides of a patient lying on the litter.
The problem which arises if the support elements are also to be able to individually pivot is solved by retaining blocks being firmly attached to the longitudinal braces and by the support elements being removably attached.
