71479 1 Operating room crane

Exemption from operations 5

The invention relates to an operating room crane for lifting and moving a patient in a hospital, which operating room crane comprises a wheeled body part, a vertical column directed upwards therefrom, to which a lifting and lowering ring is connected by means of a lifting member, on which a patient is placed. .

The operating room crane is used in hospital conditions, e.g. when transferring a patient to the operating room and lifting the patient to the operating table. The lifting circumference of the crane is usually a horizontal circumference in which the patient is placed on top of the connected transverse belts. Both ends of the straps are equipped with quick connectors so that the straps can be quickly attached to or detached from the lifting ring. The operating room crane is operated in such a way that the patient resting on the straps of the lifting ring is brought by the crane into the operating room above the operating table. Thereafter, the lifting ring is lowered so that the patient rests on the operating table on the swings. Since the patient is no longer dependent on the straps, the quick locks between the straps and the lifting ring can now be opened. The crane is then moved aside. During surgery, the straps may be left under the patient. After the cut, the crane is brought back to the cutting table and the straps are fastened to the lifting ring with quick locks.

The patient is then lifted up from the operating table by the straps and moved out of the operating room.

The operating room crane greatly facilitates patient lifting and transfer procedures in the hospital. However, there are many awkward drawbacks in the known skid crane cranes which have not been satisfactorily resolved. The object of the present invention is to eliminate the drawbacks of known operating room cranes and to provide a device which is substantially more efficient than known devices.

One of the disadvantages of the known operating room cranes is that their lifting circumference cannot be moved laterally with respect to the crane body when the 35 2 71479 1 crane is loaded. After all, it is important, for example, to place the patient in just the right place on the operating table. In order to achieve this positioning movement, the operating room crane structure according to the invention is mainly characterized in that horizontal guides are formed in the body part, on which a carriage moving on rollers, wheels or the like is mounted, to which the vertical column and its supporting perimeter are connected.

The horizontal alignment of the lifting ring is important, for example, when the patient cannot or does not want to lift by hand and thus move to the right place on the operating table.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which 15

Fig. 3 corresponds to Fig. 1 and shows a operating room crane according to the invention, the lifting circumference of which has been moved vertically and horizontally.

Figure 1 shows a side view of an operating room crane according to the invention and Figure 2 shows a top view. The crane comprises a frame 1 at its lower part, which is formed by a longitudinal beam 2 and transverse beams 3 and 4 connected to its ends. At each of the four corners of the frame frame there are wheels, shown in Figures 30 1 and 2. 5 and 6. The longitudinal frame beam 2 is further formed with beam-parallel guides 7 in which a horizontally moving carriage 8 is placed. A vertical column 9 is connected to the carriage and a vertically movable slide 10 is connected to the carriage. 12 hydraulic pumps in the hydraulic section.

3 71479 1 Attached to the upper end of the skate 10 is an actual lifting ring 13 which allows the patient to be lifted and lowered in the operating room. The structure of the circumference is shown from above in Figure 2. However, the figures do not show the transverse straps attached to the circumference on which the patient is placed.

The lifting ring 13 is fixed to the slide 10 of the vertical column 9 by a joint 14 so that the ring 13 can be tilted to raise or lower either end. To control the movement, two gas springs 15 are placed between the slide 10 and the circumference 13.

10 As the operating room crane is also used as a means of transport to move the patient in and out of the operating room, the crane wheels must be pivotable, but they must also be lockable. Thus, the wheels of the operating room crane according to the invention, which are indicated by reference numerals 5 and 6 in Figures 1 and 2, can be locked in several different ways. Locking takes place by rotating the impellers 16 arranged at the ends of the longitudinal beam 2 of the body 1. The impellers are connected to each other by means of a connecting rod so that when the other impeller is rotated, the other also rotates. It follows that the locking operations can be performed at either end of the body 1. The connecting rod 20 is located inside the beam 2 and is not shown in the figures.

Fig. 3 is a side view of a cutting hall crane corresponding to Fig. 1, in which the carriage 8 and the vertical column 9 connected to it have been moved to the left in the guide 7 of the beam 2. Since four rollers are placed inside the carriage 8, which rest on the guides 7, this lateral joint of the vertical column 9 and at the same time the lifting ring 13 can also be made when the crane is loaded, i.e. supporting the patient. In Fig. 3, the slide 10 connected to the vertical column 9 is also raised so that the lifting ring 13 and the patient possibly supported by it are raised upwards. The lifting sleeve is provided by pumping the hydraulic pump of the hydraulic part 12 in the lower part of the vertical column 9 with the foot pedal 11. Lowering of the lifting ring 13 is achieved by opening the hydraulic valve with the second foot pedal 17 shown in Fig. 2.
