Definitions

  • the invention relates to a bed for variable storage of a patient, with a frame, one with a coupling gear provided articulated hoist by a drive device can be operated with two drive units and one Mattress frame on the support elements of the articulated hoist is included, the support elements in the region of two parallel, spaced, horizontal transverse axes arranged and between a highest and a lowest Position can be raised and lowered and the support elements in protrude from the lowest position over the frame.
  • a patient With such a bedside, a patient can become therapeutic Purposes in a so-called flat position in a high position or upside down.
  • the foot high will also as Trendelenburg and the head high position as anti-Trendelenburg storage designated.
  • Trendelenburg With such a flat storage the patient lies on one level. However, this level is inclined towards the head or feet.
  • a flat storage for example in the case of a Decrease in a patient's circulating amount of blood applied.
  • a reduced blood pressure due to blood loss can such support for blood flow to the brain make necessary.
  • a flat position in head-up position used for example in traumatic brain traumas.
  • the mattress frame must be on a relatively large Stroke can be raised and lowered.
  • the nurse can adjust the bed to the desired position Adjust height.
  • a mattress rack on the mattress frame that can also be provided with several adjustable backrests can, for example, a backrest, a thigh rest and a footrest.
  • a backrest a thigh rest
  • a footrest a flat storage out additional high storage individual Overlay body parts, for example the legs or Of the head.
  • the transmission links of the coupling gear are relatively long educated.
  • the two parallel support elements that accommodate the mattress frame, in the middle under arranged the mattress frame.
  • the support elements have one relatively short distance from each other. Because of the two design features "small distance between the support elements" and "long stroke of the mattress frame” can the mattress frame when a support element is raised and a lowering of the other support element a strong one Take an incline. This can easily be so large that the downward sloping end of the mattress frame with the Frame collides. Frequent collisions with the frame can damage to the same and the mattress frame or other parts. They endanger the patient's safety.
  • limit switches In addition to the anchor devices, limit switches must also be used be provided, the drive units always then switch off when an attack has occurred.
  • Another known safety device has a drive device with sensor control. With one the stroke can be limited in terms of control technology. This However, construction is expensive and prone to failure.
  • the invention has for its object a generic To further develop the sick bed in such a way that with a light Construction inclined flat bearings in head or foot height are adjustable, collisions between mattress frame and Rack are systematically excluded and also a ease of use and good portability becomes.
  • the object is achieved in that the support elements in the area of the head or foot end of the Rack are arranged and apart so far that in a distance between each possible position of the mattress frame this and the frame.

Because the Load of a patient over the articulated hoist into the installation elements is directed between the installation elements lying areas of the frame only a very small Bending stress exposed. This allows an easy, to create an inexpensive and easily transportable frame.
  • the drive units of the articulated hoist are favorable designed as self-braking electric linear drive units. These reliable linear drive units are made in large quantities also used in other constructions and can therefore be bought inexpensively.
  • An operating device is advantageously provided with which both linear drive units can be controlled separately.
  • the Operating device allows a variable adjustment of the Sick bed.
  • the two linear drive units can be individually be adjusted. This is consecutive or also possible at the same time. It is also a training course conceivable in which an initially set inclined flat position of a mattress frame are maintained and even can be raised and lowered. Only one is required for this corresponding electronic circuit with which the desired Functions are controllable.
  • the mattress frame is preferably collapsible.
  • the folding can for example by folding over hinges or by separating the mattress frame in several parts are done.
  • the collapsible in this way Mattress frames can then easily be used in vehicles, for example transport. It is also convenient if the frame is collapsible. This can also be used for this purpose have several separation points at which there are two or more Parts can be separated.
