First aid items, and in an inclined compartment 351 for receiving a set of four 500 ml IV bottles B. The bottles are positioned at such an angle that the IV solution does not come into contact with the inner seal in the bottle neck comes. Figs. 2 and 15 show the arrangement of an adjustable Stand 38 on both sides of the stretcher 13LS and 13TJS of the middle part of the bed frame.

The inclined compartment 351 of the drawer 35 for receiving liquid containers completes the inclined Kontrο11tafelende of the electronic lifesaving device 25, so that the ä device in the stowed position is partially under the inclined drawer compartment (Fig. 2) .. This means that the device 25 does not need the rear The end of the middle part 13 of the bed frame of the stretcher protruding. .

For the embodiment of the invention, a tray-like wire frame 39 is important, which is reversibly attachable to the lower front cross member 13B of the middle part of the bed frame, either so that it protrudes forward from the storage housing and is located under the door part I4 of the bed frame, where it a battery-powered suction device 40, see FIG. 1, or so that it protrudes to the rear below the drawer 25, see FIG. To the for the '

and

Legs of certain parts of the rear frame on the middle part of the frame are tether straps for securing the upper body, arms and legs of the patient.

Finally, a pair of links 4I 'are pivotably attached to the stretcher frame (FIG. I4), the lower end of each being articulated to the support 13V and the upper end having an L-shaped slot 4IL which receives a pin 15P which is attached to the side rails 15S of the rear of the bed frame. The links 4I are provided with torsion springs 41T, which hold the links 41 in locking engagement with the pins 15P, thereby preventing the rear

Frame 15 in its horizontal extended position
hold (Fig. 1 and 5). The links 41 can be released in order to enable the pivoting movement of the frame 15 into its collapsed position according to FIGS. 1 and 14.

From the above description it can be seen that the stretcher according to the invention brings important advantages in that it facilitates the organized treatment of urgent cases, in particular of patients with a heart attack. The patient is lifted onto the stretcher and manual chest compression and ventilation are started immediately. The resuscitation device R is turned on immediately and an operator remains at the control handles of this device during the entire life-saving process. The electronic life-saving device. 25 is quickly pushed backwards and then brought into a 45 ° position in which all control handles and control devices and cable connections are easily accessible and visible. The cables of the device-25 electrocardiograph are attached to the patient, and
the EKG is read on the electrocardiograph which is visible to the operator at the head of the stretcher on the control panel on device 25.

Depending on the diagnosis made, therapy is started as follows:

A. Ventrical fibrillation, i.e. ventricular flutter -

the patient is treated immediately with the defibrillator;

B. Cardiac asystole (standstill) - the pacemaker becomes
briefly employed;

C. Medicines are given regardless of the type of cardiac arrest; drawer 35 - is of both
Sides at the head end of the stretcher are easily accessible and enable appropriate administration of drugs and IV fluids.
