Definitions

  • the object of the present utility model is a device that, in case of being suspended from a harness, allows to release the pressure suffered by the legs of the injured person through the harness fixing straps that acts with tourniquet effect.
  • the use of the harness has been generalized as a security system in different areas of the labor world, such as construction, tree pruning, the wind sector and, in general, any work that is performed at height and that carries the risk of suffering any type of fall. Although its use is becoming widespread, unfortunately, deaths due to falls are still one of the main causes of death in the workplace. In general, the reasons for these deaths are varied, but they correspond to an inadequate, badly used or directly non-existent material.
  • the standard safety device for work at height is the harness.
  • the fall of a subject by a harness and subsequent arrest may not be the most dangerous part of the accident.
  • the anchoring systems and the harness itself have resisted, the injured person remains in the most dangerous phase, which is the suspension phase, which, if it lasts for a long time and the rescue becomes more complicated, can It is very dangerous, especially if the victim is unconscious or unable to move during the duration of the suspension.
  • Suspension trauma also known as harness syndrome or orthostatic syndrome, is a set of symptoms that appear when a person is hanging for a brief period of a harness and there is a combination of two factors: immobility and suspension.
  • Immobility can occur both in people who are unconscious, as in people who reach exhaustion, which ends up causing the person to be suspended for a period of time that the longer it lasts, the more damage it will cause in the victim.
  • the suspension situation will produce an accumulation progressive blood in the legs due to a failure in the venous return, since the harness straps act as a tourniquet preventing, totally or partially, the passage of blood to the heart.

  • the combination of the shock caused by the position in which the injured one is and the compression on the abdomen causes an important respiratory difficulty that leads to the victim who is suspended to death in a short period of time.
  • the chances of survival when the suspension lasts more than two hours are scarce. It is important to remember that the death of the victim due to this cause may occur during the suspension or after the rescue.
  • the most probable cause of the death of the rescue is the acute overload of the right ventricle of the heart due to a massive arrival of blood that is retained in the lower extremities by the tourniquet effect of the harness itself.
