Description

The invention relates to a system for rapid loading, loading and unloading of patients on carriers in ambulance and a corresponding ambulance.

In ambulances, among the well-known include emergency ambulance and ambulance, there are special forms that are used in the fields of civil protection, rapid response groups and the military. A typical representative of a military ambulance is the 4-carrier ambulance.

This type is primarily used to transport lightly injured people who do not require acute care while driving or who need to be evacuated immediately from a danger zone in the event of a military attack.

A typical design includes a structure with four straps, each side are located on the left and right of the vehicle wall two carrying racks superimposed, on each of which two patients can be spent on each other.
The carrying devices are usually folded up, so that a flat and large cargo area for other purposes in case of non-occupancy by patients arises. This can be, for example, for a space-saving re-functioning of the carrying racks for the use of seating for the slightly injured, as is done in the Bundeswehr. Also mixed forms with one, two or three carriers are possible. The Bundeswehr works around the carrying racks in such a way that up to 6 lightly injured persons can be transported more space-saving.

A concrete realization of a patient transport vehicle shows AT 233165 B , with a folding arrangement of two lateral stretcher platforms and a carrying platform in the middle for transporting up to 5 patients.

The EP 2 366 369 B1 describes a support module that includes a telescoping base unit for receiving a patient support.

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 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 rollable stretcher on board a vehicle, wherein in the movable support a telescoping on the ground ramp is mounted and guided. The ramp is driven by the stretcher to then move it into the vehicle.

Due to the very tight space conditions in special vehicles, especially in military vehicles with and without armor, the patients to be transported often have to be accommodated in niche-like areas within the vehicle, the access is usually very small openings in the vehicle. In addition, there is typically a considerable height difference between the loading level, the surrounding soil / terrain level and the patient positioning position in the vehicle, so that the loading height is well above the civil demands to be considered in the context of DIN EN 1789_2014-12 regarding the maximum values of loading height and loading angle ,

It is an object of the invention to provide a lightweight and flexible loading and unloading system for rapid transport positioning of at least one patient, on or several levels, under spatially close conditions, such as those present in a military means of transport, with an individual setting of Beladewinkels or loading height to create.

This object is achieved with the carrier loading system according to claim 1. Advantageous embodiments of the invention are the subject of dependent claims. A patient transport cart employing the carrier loading system is claimed in claim 10.

With the carrier loading system according to the invention, it is possible to quickly and flexibly bring at least one lying on a stretcher in a vehicle or means of transport or environment and later unload it, the storage of the patient takes place at least on one level in a patient transport car.
Likewise, the invention can also be used for emergency ambulance, ambulance, as well as for other situations, the cramped conditions and large differences in height in the load such as wounded transport in a mobile shelter or container.

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

The invention essentially consists of a positioning device, which is connected to a telescopic central unit which receives the patient support. The positioning device is responsible for the inclination and vertical position or height of the central unit, which is designed so that two independently movable struts are used, which considered laterally over the entire stroke (ie in a direction perpendicular to the plane of movement of the struts; Direction corresponds to the transverse direction of the patient support, if this is intended to be arranged on the central unit) have an intersection. In other words, the struts are not interconnected and thus can cross freely.

The struts may also be implemented as multiple parallel strut pairs or a mixture of a parallel pair and a single strut according to the previous conditions similar to a scissors table. The struts are preferably mounted at opposite ends of the central unit with respect to the longitudinal direction (corresponding to the longitudinal direction of the patient support, insofar as it is intended to be attached to the central unit) and are moved via an actuation system. As actuation system for the struts, which are rotatably mounted on the central unit or on the vehicle, linear actuators are expediently used, which make a force or movement initiation in the struts and thereby control the tilting over the transverse axis and the height adjustment of the central unit.
A control can be done individually manually, semi-automatically or fully automatically, depending on the control or control device used.

The above-mentioned central unit can be designed such that it contains receiving elements for the patient support, which allow (advantageously a guided) lateral movement, perpendicular to the movement plane of the patient support conveyed by the positioning device. This is particularly advantageous for a displacement of the patient support from the carrying loading system into predetermined carrying receptacles within the ambulance.

For loading the central unit, an integrated into the central unit guideway for the receiving element is advantageous, which allows a longitudinal movement during loading and unloading.

The central unit forms the interface for receiving the patient support, wherein the insertion of the support into the receiving elements, which are positioned on the central unit takes place.

The invention will be described with reference to a concrete embodiment with reference to Fig. 1 to 13 explained in more detail:

In Fig. 1 to 4 is an exemplary representation of the invention carrying loading system T shown in different states and in the Fig. 5 and 11 a corresponding ambulance. The carrier loading system T comprises as essential elements a positioning device P and a telescopic central unit Z and z. B. on a patient transport vehicle (see Fig. 5 ) can be arranged.

The central unit Z includes the receiving elements A for the patient support, guide track F for the movement of the receiving elements A in the longitudinal direction and the telescoping device TP.
The telescoping device TP consists, as in the example in Fig. 4 to see at complete telescoping of the central unit Z, from the two telescopic elements TE, as well as the outer frame R of the central unit Z, which forms another telescopic element.

The positioning device P includes the independently movable and freely intersecting struts S1, S2. How to look in particular from the Fig. 1 detects, the freely crossing struts are not connected to each other and have in the embodiment shown for each of the two struts S1, S2 each have a parallel strut. In the following, two parallel struts together with S1 and S2 are referred to.

The two independent struts S1, S2 are rotatably connected to the central unit Z (see Fig. 2, 3rd . 4 ). An actuation system comprises the movement units B1, B2, the concrete embodiment in the illustrated example showing a movement of the struts S1, S2 via 3 actuators, two actuators on the strut S1 and an actuator on the strut S2. At least each independent strut (or parallel strut pair) S1, S2 requires an actuator, so that at least two actuators form the movement units B1, B2. The actuator may, for example, as in Fig. 2, 3rd . 4 be designed as a linear lifting cylinder, which has a piston with cylinder eye.

The attachment of the struts S1, S2 and movement units B1, B2 typically takes place on the vehicle structure. The lower end of the strut S2 (see Fig. 2, 3rd . 4 ), which is not connected to the central unit Z and is located on the Beladeöffnungsnahen side of the positioning device P, is mounted rotatably mounted on the vehicle structure.
The lower end of the strut S1 (see Fig. 2, 3rd . 4 1), which is not connected to the central unit Z and located on the loading port remote side, is rotatably mounted on the cylinder eye of the moving unit B1 as shown in the example, and thus is linearly movable, ie, the lower end of the strut S1 becomes linear in the moving direction of the lifting cylinder moves (see stroke change from B1 to FIGS. 2 and 3 ). In the case of the movement unit B1, the actuators are fixed to the vehicle structure or, in the case of the movement unit B2, the actuator is connected rotatably to the latter, wherein the angle between the longitudinal axis of the actuator and the longitudinal axis of the vehicle changes during the movement (see position of B2 in FIG FIGS. 2 and 3 ).

Fig. 2 to 4 show a schematic representation of the movement and Teleskopierzustände the Carrying loading system T in side view, orthogonal to the lifting and Teleskopierrichtung the central unit Z. The positioning means P changed by controlling the moving units B1, B2, visible from the change of Aktuatorenhubs and the position of the cylinder eyes Deflection of the struts S1, S2 with respect to height and inclination of the central unit Z, whereby the height change from H1 to H2 corresponding to H2 = H1 + ΔX in the Fig. 2, 3rd results.
It can be seen here that the projected fictitious crossing point of the struts S1, S2, in the representation of the movements in the Fig. 2-4 according to moves, from Fig. 2 to Fig. 3 moves up and finally at Fig. 4 has moved to the lower right in the image, thus can move freely in the plane, which is a significant advantage compared to a scissor table, which includes only one degree of freedom along its axis of motion.

Fig. 4 shows a possible receiving position for the patient support PT, which shows the fully telescoped central unit Z with the telescopic elements TE, wherein the angle alpha α indicates the inclination of the central unit Z with respect to the longitudinal axis of the transport, which by appropriate control of the movement units B1, B2 in Each position of the central unit is individually adjustable.
In addition, one sees the rotatable attachment points BP of the struts S1, S2 indicated on the central unit structure, as well as the storage points or pivot points for the movement units B1, B2, which are shown in this example as actuators. The struts S1, S2 are rotatably mounted longitudinally at various locations on the central unit Z, on the near and far side relative to the loading opening.

A typical value for the loading angle Alpha α is 16 °, however, angles of 0 ° can be approached to the technical limits in the positive and negative directions of rotation, with only positive angles having a practical relevance for the load, since this reduces the transfer height effect of the loading process. If the angles are too large, there is a risk of the patient slipping off the stretcher.

The Fig. 5 to 13 show exemplarily a Beladeablauf to explain the invention and its function divided into a choice of 8 steps.

Fig. 5 shows a schematic representation of a section of a 4-carrier ambulance during loading or unloading the patient support PT, wherein rough outlines of the vehicle transport space Fz are outlined and 4 stretcher receptacles TA are recognizable with a corresponding guide FA in the transport space.

The invention and its function will be described using the example of the loading, wherein the Fig. 6 to 13 the loading process divided into representative steps show. This process follows the preparation phase, according to Fig. 1 to 4 in which the carrying loading system T, is moved into the receiving position by tilting and telescoping the central unit Z.

The receiving elements A are individually and free to remove or insert from the guide FT or F of the central unit Z (similar to how inserts in a magazine or within which are moved). For patient accommodation, the receiving elements are placed in the corresponding guides FT and the upper receiving element A along the guideway F to the lower end, the closer to the bottom and inclined side, moved. After carrying out said steps, the sequence of which can be carried out variably, the carrying loading system T is prepared for receiving the patient support PT in the setting-up phase.

Step 1 according to Fig. 6 shows the positioning of the system to a receiving angle alpha α, this angle, the transfer or receiving height conditions, the central unit Z is fully telescoped and the positioning of the upper receiving element A has been carried out in the receiving position for receiving the patient support PT. Fig. 5 . 6 shows the patient support PT, wherein the head-side supporting feet TF are already inserted into the upper receiving element A, expediently, the receiving element A includes a lock. The said locks the support feet TF serve to increase the security, but are not a prerequisite for the inventive implementation of the carrier loading system T.

Subsequently, step 2 follows the pushing up of the receiving element A, along the guideway F, this can be designed for example as a C-rail, with the patient to the upper end position. In this position, the foot-side support feet TF in the lower nor free receiving element A, which is located in the guide FT, set down and conveniently locked. The now reached position shows Fig. 7 ,

In step 3, the complete telescoping of the central unit Z is reduced to an intermediate position, after which the change of the inclination to the horizontal is achieved by movement of the struts S1, S2. This will be in Fig. 8 achieved by the complete insertion of one of the telescopic elements TE. This intermediate position can be provided according to the respective requirements arbitrarily between the basic position (undelivered) and the complete telescoping. Even if a complete withdrawal of the telescoping of the central unit Z without intermediate position in one step would be possible, the introduction of the patient for ergonomic reasons, as shown advantageously via the intermediate position.

The introduction of the central unit Z, regardless of whether there is a patient support PT as described above, is done manually by a sliding movement into the vehicle until reaching the intermediate position. If necessary, the angle α α of the central unit Z can be reduced for easier movement. The application of force for the sliding movement takes place either via the frame of the central unit Z or via the patient support PT.

A complete withdrawal of the inclination angle alpha α takes place in step 4 (FIG. Fig. 9 ), if not already done in step 3, this leads to a horizontal orientation alpha α = 0 ° of the central unit Z. Subsequently, the insertion (step 5) of the remaining telescoping takes place, wherein now all telescope elements TE are within the central unit Z, according to Fig. 10 , The telescopic device expediently includes TP interlocks.

In Fig. 11 According to step 6, the vertical positioning of the carrier loading system T is carried out to the desired transfer height of the carrier mount TA. How to get in FIG. 5 recognizes, there are 4 carrier tapes TA on two different levels. After reaching the transfer height and releasing the appropriate locks of the receiving elements A takes place a lateral movement of the receiving elements A along the guide FT in the direction of the support holder TA in accordance Fig. 12a, 12b (Step 7), wherein the carrying receptacle TA expediently contains guides FA (eg rails) for the receiving elements A.
After moving the patient along the guides FT, FA according to the arrows of Fig. 12a, 12b in the final position according to Fig. 13 , an appropriate locking of the receiving elements A. takes place. This represents the transport position, in which the further transport is possible with the ambulance.

The unloading process should be carried out in the reverse order of steps 1 to 8. For the further loading with patients, a new pair of receiving elements A is to be inserted into the central unit Z for each further patient support PT, to be taken correspondingly during the unloading process, then the procedure is as described above.
The storage of the receiving elements A takes place advantageously within the transport vehicle. The attachment of the carrier loading system T in the appropriate means of transport eg in the vehicle compartment, work space, containers, mobile shelter, truck bed, etc., takes place in a connection method known to the person skilled in the art, for example by direct screwing to the transport structure or indirectly when using a corresponding adapter, so that this Item is not described in detail.

The folding stretcher supports TA are to be mounted in the vehicle so that a transfer of the receiving elements is ensured at the appropriate transfer level, in which case a corresponding guide or lock on the stretcher receptacle is expedient. An attachment of the stretcher support in the vehicle, as well as any lowering variants, are not described in detail and are expertly for the use of the carrier loading system T execute.
