Definitions

  • the present invention finds its field of application in the pronation technique, which allows varying the diaphragmatic mobility of the bedridden patient without autonomous body movement capacity, allowing improvement in the ventilation and cleaning of the patient's body, while preventing the formation of the dreaded bedsores and the creation of acute lung infections.
  • CN 110584911 A patent teaches a pronation bed which has independently articulated rigid planes. Although this document allows partial rotation of the patient's body, it does not solve the problem of placing the patient face down, that is, turning him 118 Q on its axis and the bed does not rotate, it only allows the elevation of segments on the sides of the herself.
  • Document CN 203138904 U illustrates another pronation bed, consisting of a rigid plane on which the patient rests, secured to said plane and is rotated up to 180 Q next to said support plane, with the result that the patient is face down but hidden by said plane, which prevents any cleaning and healing operation of the back of the same. That is, this embodiment is only effective in rotating the patient's body, but with the aggravation that it is hanging upside down from the retention straps or tapes, or from a semi-cylindrical envelope that contains it as a capsule, making it impossible access to the patient's body when pronated.
  • the CN 209059728 U Utility Model presents a structure with two ends or ends consisting of respective vertical planes.
  • a first horizontal frame is linked to said planes, which has the particularity of rotating on a longitudinal axis.
  • a second frame is arranged parallel to the first frame and between both frames the patient is positioned and retained, the first frame being grippable when pronation ends, which allows access to the body of the patient thus rotated.
  • This construction is useful for turning the patient's body but lacks lateral protection, which means that it cannot form a proper bed.
  • Publication US 2002/0138906 A1 by Bartlett, teaches a pronation bed that has a structure at the ends of which two parallel vertical circumferential rings are located. To these rings is linked a bed which rotates on the tracks provided by said rings, and the patient is retained by a series of selectively folding padded arms.
  • the defect of this embodiment is that, apart from presenting a highly complex structure and Very high cost, the patient being left low is suspended, settling against the referred padded arms and the body is hidden by the bed on which it originally rested. Removing the original support mattress is feasible, but it is an operation made difficult by the presence of the aforementioned folding arms.
  • US patent 6,701,553, to Barry D. Hand more than a pronation bed, is a device for the pronation of the patient, which can be carried to the same on a special stretcher which is secured to the frame with axial rotation capacity supported by two structures at each end. Once the stretcher is secured with the patient, it is retained by padded means, and when the rotation occurs, a lower mat is liftable so that the patient rests on it and the stretcher is removed.
  • This pronation device does not form a bed for the patient, so that it must be transferred from its resting place to the device, on the space table mentioned above.
  • Document US 2002/0016994 shows another pronation device, which is of very complex construction and high cost. It consists of a base with a semicircular seat or track on which a stretcher specifically designed to be attached to this device sits. The stretcher is raised on a column and the patient is brought into contact with an upper mat held by a horizontal plate that is attached to a semicircular leather, which couples with the lower track and allows 180 Q rotation on its axis. It is observed that this pronation device cannot, due to its complexity, constitute a bed where the patient usually rests, which must be transported from his bed to this device.
  • the Korean patent KR 2001 10071589 (A) is another ad hoc construction for pronation, but it does not constitute a usual patient bed.
  • This structure is also complex and expensive and comprises a base with wheels, with a head in which a pair of horizontal beams defining a fork-shaped frame is rotatably attached to which a specifically designed stretcher is attached. It presents laterally articulated padded means pivoting on the plane of the stretcher that immobilizes the patient and allows its 180 Q rotation.
  • This embodiment is not suitable for toilet treatments or interventions carried out on the patient on this same construction,
  • US patent 6,282,736 to Barry D. Hand covers a construction somewhat similar to the previous one: it consists of a base and a head in which a cantilevered bed sits rotatable on its axis, on which the patient, which is trapped by a lid that closes on the bed, which allows the patient to rotate up to 180 Q. The patient must then be removed, already pronated, and rested on an additional stretcher. It turns out then that this last construction, which is expensive to manufacture, does not constitute the bed where the patient usually rests and is only useful for pronation.
  • the objective of the present invention is a bed where the prone patient can rest, and which at the same time can act as a pronation device, without the need to transfer the patient. [0018] It is an objective of the invention that said bed allows the patient to rotate at selective angles on its axis from 0 Q to 180 Q.
  • the object of the invention is that the feeding guides, assisted breathing and other conduits and / or connectors to control devices and instruments are free from any interference when the patient's body is turned.
  • this bed / pronation device be of low cost, without maintenance of motor means.
  • the object of the invention is the patient's bed rest, and by means of a quick and simple execution, it becomes a pronation device, and then to turn it back into the same bed of rest, but with the body turned on its axis.
