Description

Description

The invention relates to an ambulance for small children with a treatment room that is accessible via a side door of the vehicle and separate from the driver's cab, in which supply and monitoring units, such as compressed air and oxygen cylinders and pressure and supply indicators and medical treatment and observation devices, installed partly permanently and partly interchangeably, are arranged, as well as a treatment and transport table arranged transversely to the direction of travel for receiving a transportable incubator, wherein the treatment and transport table comprises an upper and a lower frame, the upper of which is held in a high working position by at least one swivel support hinged to both frames so as to be pivotable about parallel axes and can be lowered towards the vehicle floor in a movement path directed in a translational manner to the vehicle's longitudinal axis.

In a known ambulance for small children, the transport and treatment table can only be adjusted manually between a lowered receiving position and a raised transport and treatment position, whereby lifting the treatment table loaded with the incubator requires a relatively large amount of force despite the use of weight compensation springs. Furthermore, the known transport and treatment table can also be manually adjusted to different heights of the transport or treatment position using plug-in devices by lengthening or shortening the telescopic swivel supports accordingly, which is particularly advantageous for adjusting to the height of the treatment staff, but such an adjustment is either not possible at all or only with extreme effort when the treatment table is loaded with the incubator, particularly due to the very cramped conditions in the ambulance.

be made.

"The invention is based on the object of creating, in conjunction with a small child ambulance, equipment and in particular a transport and treatment table for the incubator, which facilitates loading and unloading of the incubator and at the same time also makes it possible to hold the incubator, if necessary, at a height within the vehicle that is required for the treatment of the patient and does not correspond to either of the two end positions of the treatment table.

This object is essentially achieved according to the invention in that the treatment and transport table is equipped with a pressure medium-operated lifting unit that switches off automatically in at least one of the end positions of the upper frame. In this case, the invention also provides in particular that the treatment table consists in a known manner of a base frame and a table frame supporting the incubator as well as two swivel supports that are pivotably connected to both frames about axes that are parallel to one another, and the lifting unit, in particular a lifting cylinder, of the lifting unit is arranged congruently with the longitudinal center of the table and is connected to the table frame in alignment with the articulation axis of one of the two swivel supports.

This creates a transport and treatment table that is adapted in size to be accommodated in the rescue vehicle, which ensures that the incubator can be easily loaded and unloaded and also makes it possible to adjust the height of the treatment table loaded with the incubator to the required treatment or the height of the treatment staff during the journey. The pressure medium supply for the lifting unit can be derived from the vehicle's own pressure medium sources or from these

be designed independently. The lifting unit can also be designed as a hydraulic or pneumatic system.

In a preferred implementation form,

that the lifting unit is an electro-hydraulic unit with

a pressure pump driven by an electric motor

and a hydraulic cylinder piston and switching valves

designed and is arranged or supported on the floor frame of the treatment table.

Preferably, it is further provided that a mechanical weight compensation spring for the incubator is assigned to the pressure medium-operated lifting unit, wherein the weight compensation spring is expediently penetrated by a rod and is supported on the one hand by a joint against the floor frame and on the other hand engages one of the pivot supports.

It is also advantageous for the weight relief spring to be arranged congruently with it below the lifting unit in the longitudinal center of the table, whereby the lifting unit and the weight relief spring are supported by joints pivotable about mutually parallel axes on successive cross members of the floor frame of the treatment table.

In a further embodiment, it is further provided that the ζ lifting unit is assigned a limit switch arrangement, at least for the limit switch when the upper table frame is in the raised end position, consisting of a switching cam connected to the table frame and a switch supported on the base frame via an upstanding support, wherein the switching cam and switch of the limit switch arrangement are expediently arranged on the inside opposite the longitudinal beams of the table and base frame.

To ensure the stability of the treatment table even in the event of a failure of the pressure medium supply for the lifting unit, it is finally provided that

The lifting unit, in particular a lifting cylinder 15, of the lifting unit 14 is arranged in the embodiment shown so as to be congruent with the longitudinal center of the table and is pivotably connected to the table frame 8 about an axis aligned with the articulation axis 10 of one of the two pivot supports 12. The lifting unit 14 is designed as an electro-hydraulic unit with a pressure medium pump 17 driven by an electric motor 16 and a hydraulic cylinder piston forming the lifting unit 15 as well as switching valves 18 and is arranged on the base frame 9 of the treatment table.
