Description

The invention refers to a carrying module for moving a patient carrier from a patient storage position to a patient receiving position and vice versa.

In armored ambulance vehicles, space is generally very limited, and the patients to be transported often have to be accommodated in niche-like spaces within the vehicle. In addition, there is typically a considerable height difference between the loading plane (e.g., ground) and the patient positioning position in the vehicle.

The DE 2620939 A1 describes a stretcher storage rack with pivoting and telescoping guide rail for guiding a stretcher receiving a sub-stage.

The DE 2200814 B describes a frame for a stretcher, wherein the stretcher receiving frame frame is supported during extension via a hinged to the frame frame support arm in longitudinal guideways.

The DE 1541315 A describes a tiltable about a transverse axis support platform, wherein the tilting movement is generated by means of a linkage and supported by resilient means.

The GB 2286813 A describes a merely laterally movable support for a stretcher on board a vehicle, wherein in the movable support a telescopic ramp is mounted and guided on extension. In the course of the Extension is a pivoting down. The ramp bridges the height difference between the beam and the ground, allowing the stretcher to move from the vehicle to the ground.

It is an object of the invention to provide a support module for a patient support, with a safe and gentle for the patient loading the patient support is possible, especially in tight spaces and large difference in height between the loading level and patient positioning position.

This object is achieved with the support module according to claim 1. Advantageous embodiments of the invention are the subject of dependent claims.

The carrying module according to the invention makes it possible to load a patient carrier loaded with a person, in particular into a vehicle. Here, a height difference between loading level / ground and vehicle can be compensated. Loading is possible even in confined spaces within the vehicle, e.g. Vehicle superstructures are present on the sides of the patient positioning position. Finally, accessibility in one spatial direction is already sufficient for loading the patient support.

The inventive solution is characterized by an easy to handle and safe operating concept. It can also be designed as a lightweight construction.

In addition to the already mentioned loading of a patient into a civilian or military vehicle, however, the carrying module according to the invention can also be used in other situations in which the conditions mentioned (limited space, great height difference) are relevant, e.g. also in the transport of wounded in a mobile shelter or container.

The invention will be explained in more detail with reference to a concrete embodiment with reference to FIG.

Fig. 1a / 2a / 3a / 4a

In FIGS. 1a / 2a / 3a / 4a, the carrying module 10 according to the invention is shown in the completely contracted state. The support module 10 comprises as an essential element the telescopic base unit 9, on which the stretcher 50 (see Fig. 2 ) is arranged. The base unit comprises an outer 8 and an inner telescopic element 7 which can be pulled out of the outer telescopic element (see the following Fig. 1c / 2c / 3c / 4c ). Furthermore, a guide device is used to move the telescopic base unit. The guide device comprises parallel to the direction of movement of the base unit side cheeks 5 right and left of the base unit 9 with therein integrated guideways 51 (see Fig. 3b ). The side walls 5 are connected via the bearing 3.4 fixed to the vehicle.

The one in the Fig. 1 a / 2a / 3a / 4a shown state of the support module 10 corresponds to the patient storage position, ie the state before the start (when unloading) or after completion (when loading) of the loading process. The support module is completely inside the vehicle in this state ( Fig. 4a ) arranged. In this state, the support module or its moving parts is secured by bolts against movement in all directions. Bolt 1 locks the front receiving element 20 of the stretcher. Bolt 2 locks the rear receiving element 15 of the support 50 and additionally the base unit 9 in the side walls. 5

Fig. 1 b / 2b / 3b / 4b

To change the position of the carrying module in FIG. 2 To reach the base unit 9 must be backwards (definition rear / front see Fig. 1a - in the application in the vehicle according to Fig. 4 means rear out of the vehicle) to be moved. First, the lock 32 must be pressed, this pulls the bolt 2 the side cheeks 5 out. However, the bolts 2 still lock the receiving element 15 of the patient support. Now, the base unit 9, in which is pulled on the handle 12, be moved backwards. The base unit 9 is guided by way of a front bearing 29, which is located in the guide track 51 (see FIG Fig. 3b ) rolls along the side walls 5, and via a shaft 30, on which the base unit 9 rests. The guideway 51 in the side wall 5 is designed so that by the ratio of front bearing 29 to shaft 30, the base unit 9 lowers when pulling down and thus the position as shown in the Fig. 1c / 2c / 3c / 4c is shown reached. The exact course of the lowering of the support 50 can be determined by the course of the guide track 51 relative to the position of the shaft 30. The guideway 51, as shown in the 3D representation of the Fig. 3b has, for example, three substantially rectilinear partial passages. In its wave-distant partial passage, it has a horizontal course (whose height level is slightly above the height of the shaft 30), but then goes over in a linearly increasing range. This means that the closer the withdrawal of the base unit 9, the front bearing 29 of the shaft 30 comes, the greater is the distance measured in the vertical direction between the bearing and the shaft 30. In the 1 b / 2b / 3b / 4b is the base unit 9 furthermore in the non-telescoped state, ie the inner telescopic element 7 (FIG. Fig. 1c ) is still completely in the outer telescopic element 8 ( Fig. 1 c) ,

Fig. 1c / 2c / 3b / 4c

To change the position of the carrying module in Fig. 1c / 2c / 3c / 4c to reach, the locking pin 22 must be actuated. Now, the inner telescopic element 7 can be moved out together with the support 50 and the associated support receiving elements 15,20 from the outer telescopic element 8 of the base unit 9. The outer telescopic element 8 is designed slotted, so that the two support-receiving elements 15,20 can run during the extension of the inner telescopic element 7 therein. When driving in, the locking bolts 22 lock the inner telescopic element 7 automatically. When moving out of the inner telescopic element 7, the front support receiving element 20 moves out of the locking link 11 and unlocks the bolt 1 automatically. When driving in takes place through the locking link 11 also automatically a lock. By unlocking the front foot of the stretcher is only in 20 stretcher element, but is no longer secured by the bolt 1. The inner telescopic element 7 reaches its end position when moving out through an end stop.

Fig. 1 d / 2d / 3d / 4d

To change the position of the carrying module in Figure 1d / 2d / 3d / 4d To reach the lock 32 (see Fig. 1 a) of the rear stretcher member 15 are fully opened. The bolts 2 are pulled into the center of the rear stretcher member 15 and release the foot of the stretcher 50 at the rear. The stretcher can now be lifted out of the rear stretcher receiving element 15. By moving the stretcher 50 rearwardly, the front stretcher member 20, which still supports the front feet of the stretcher 50, descends in the slotted inner telescoping member 7 until it rebounds against a cushioning in the rear stretcher member 15 , Thus, the stretcher 50 has arrived in the patient receiving position where it can be loaded and unloaded.

When retracting the carrying module, the procedure is reversed.
