Abstract
Description
Die Erfindung betrifft ein Antudekubitus-Bett.The invention relates to an anti-decubitus bed.
Es handelt sich um ein Bett für Langzeitkranke, bei dem die Matratze auf zwei getrennten Reihen von Querplatten aufliegt, die mit Abständen angeordnet sind und durch zwei getrennte bewegliche Ebenen getragen werden, die sich mit alternierender Bewegung vertikal bewegen.It is a bed for the long-term sick, in which the mattress rests on two separate rows of transverse plates that are spaced apart and supported by two separate movable levels that move vertically with alternating movements.
Die Matratze wird alternierend durch die eine oder die andere Reihe von Platten gestützt und bleibt dabei immer auf der gleichen Höhe. Auf diese Weise ändern sich die Kontaktpunkte zwischen der Matratze und dem Körper des Patienten ständig.The mattress is alternately supported by one or the other row of sheets and always remains at the same height. In this way, the contact points between the mattress and the patient's body are constantly changing.
Die Apparatur wurde zur Behandlung und zur Vorbeugung von Dekubitus-Wunden konzipiert und besitzt dafür ein System zur zyklischen Änderung der Abstützpunkte des Körpers auf der Matratze und erlaubt somit die Blutzirkulation des Patienten in sämtlichen Teilen der Körpers.The device was designed for the treatment and prevention of pressure ulcer wounds and therefore has a system for cyclically changing the support points of the body on the mattress and thus allows the blood circulation of the patient in all parts of the body.
Es gibt auf dem Markt mehrere Antidekubitus-Betten, diese weisen jedoch verschiedene Mängel, wie die Notwendigkeit periodischer Eingriffe der Krankenpfleger oder der Bewegung des Körpers des Patienten mit entsprechenden schwerwiegenden Unbequemlichkeiten für denselben, auf.There are several anti-decubitus beds on the market, but they have various shortcomings, such as the need for periodic nursing interventions or the movement of the patient's body, with corresponding serious inconveniences for the patient.
Ausgehend von diesen Voraussetzungen wurde ein neues Antidekubitus-Bett entwickelt und realisiert, das durch automatische zyklische Variierung der Abstützflächen das Auftreten von Dekubituswunden ohne die Notwendigkeit ständiger Bewegungen durch das Betreuungspersonal vermeidet.Based on these prerequisites, a new anti-decubitus bed was developed and implemented, which prevents the occurrence of pressure sores through the automatic, cyclical variation of the support surfaces without the need for constant movements by the care personnel.
In den beigefügten Zeichnungen wird die praktische Ausführung der Erfindung in einer für den Fachmann zu deren Durchführung ausreichender Form dargestellt. Das Bett besteht in seinen Hauptteilen aus einem festen Haupttragrahmen (A) auf vier Rädern, die gehoben und gesenkt werden können, wobei zwei der beiden Räder frei drehbar und die beiden anderen fest und mit Bremsmöglichkeit ausgestattet sind.In the accompanying drawings, the practical embodiment of the invention is shown in a form sufficient for the person skilled in the art to carry it out. The main parts of the bed consist of a fixed main support frame (A) on four wheels that can be raised and lowered, whereby two of the two wheels can rotate freely and the other two are fixed and equipped with braking facilities.
Der genannte feste Hauptrahmen trägt zwei bewegliche Rahmen (B1, B2), die jeweils mehrere Stützen (C1, C2) aufweisen, welche Platten (Tragelemente/Leisten/Gurte) (D1, D2) in Queranordnung, die die Matratze (E) tragen, stützen.Said fixed main frame carries two movable frames (B1, B2), each of which has a plurality of supports (C1, C2), which plates (supporting elements / strips / belts) (D1, D2) in a transverse arrangement, which carry the mattress (E), support.
Der Abstand zwischen je zwei Platten (Tragelementen, Leisten D1, D2) jedes Rahmens ist so, daß der Einschub einer Platte des anderen Rahmens in der Weise möglich ist, daß eine doppelte Abstützfläche für die Matratze geschaffen wird. Die beiden Rahmen bewegen sich alternierend und zyklisch in der Weise, daß die Person auf konstankter Höhe ruhig liegenbleibt, sich aber die Abstützpunkte ändern.The distance between two plates (support elements, strips D1, D2) of each frame is such that the insertion of one plate of the other frame is possible in such a way that a double support surface for the mattress is created. The two frames move alternately and cyclically in such a way that the Person remains at a constant height, but the support points change.
Die Hubbewegungen der Rahmen erfolgen periodisch, wobei dieser Rhythmus in der Weise geändert werden kann, daß Zyklen verschiedener Dauer je nach Zustand des Patienten gewählt werden können. Die Bewegungen der beiden beweglichen Rahmen erfolgen in der Weise, daß, wenn sich der erste Rahmen in der Position der größten Höhe befindet (Phase D), also den Patienten trägt, der zweite Rahmen abzusinken beginnt, bis er den unteren Totpunkt (Phase A) erreicht; anschließend beginnt der zweite Rahmen bis zum oberen Totpunkt zu steigen, wo er den Patienten übernimmt (Phase B), und zu diesem Zeitpunkt beginnt der erste Rahmen bis zum unteren Totpunkt abzusinken (Phase C), um dann wieder anzusteigen, den Patienten wieder zu übernehmen, womit ein neuer Zyklus begonnen wird (Phase D).The lifting movements of the frames take place periodically, and this rhythm can be changed in such a way that cycles of different duration can be selected depending on the condition of the patient. The movements of the two movable frames take place in such a way that when the first frame is in the position of greatest height (phase D), i.e. carrying the patient, the second frame begins to drop until it reaches bottom dead center (phase A) reached; then the second frame begins to rise to top dead center, where it takes over the patient (phase B), and at this point the first frame begins to drop to bottom dead center (phase C), and then rises again to take over the patient again which starts a new cycle (phase D).
Auf diese Weise wurden zwei Reihen von Abstützflächen in getrennter und alternierender Form geschaffen, die es dem Patienten im Liegen ermöglichen, die Abstützpunkte ständig auszutauschen, ohne daß dabei Bewegungen oder Änderungen der Höhe eintreten, also ohne daß er in irgendeiner zusätzlichen Form gestört wird.In this way, two rows of support surfaces were created in separate and alternating form, which enable the patient lying down to constantly replace the support points without any movements or changes in height, that is, without being disturbed in any additional form.
Die beiden Rahmen werden jeweils durch den hydraulischen, einfach wirkenden Zylinder bewegt. Sie werden sukzessive über Drei-Wegeventil mit einem einstellbaren Potentiometer verbunden. Das Ganze wird durch eine gedruckte Schaltung gesteuert, die mit 24 Volt Strom versorgt wird, der direkt aus dem Netzstrom heruntertransformiert wird.The two frames are each moved by the hydraulic, single-acting cylinder. They are successively connected to an adjustable potentiometer via a three-way valve. The whole thing is controlled by a printed circuit, which is supplied with 24 volts of electricity, which is transformed directly from the mains current.
Jede Platte Leiste/Gurt D1/D2 wird durch zwei Rollen (F1,F2) über den Stützen der Rahmen getragen. Die genannten Platten werden durch zwei seitliche Federn unter Spannung gehalten, die ein Absinken der Platte ermöglicht, wenn der Patient bewegt wird bzw. sich selbst bewegt.Each panel bar / belt D1 / D2 is carried by two rollers (F1, F2) over the supports of the frame. The plates mentioned are held under tension by two lateral springs, which allow the plate to drop when the patient is moving or moving.
