Abstract

The cushion (1) is connected to an electro-pneumatic unit (3) comprising a pressure distributor (4), a pressure sensor (6), a membrane air pump (7), an electro-pneumatic valve (8), and a rechargeable battery (12). The data obtained by the sensor (6) are transmitted to a control device assembled of a microprocessor (13) and an adjustable potentiometer (14). The pressure within the cushion (1) is changed as required in order to avoid the patient developing a decubitus.

Description

Stark in der Bewegung eingeschränkte Menschen, wie zum Beispiel Tetraplegiker, also an allen vier Gliedmaßen Querschnittsgelähmte, sind nicht in der Lage ihre Sitzposition regelmäßig zu entlasten. Durch den konstanten Druck auf eine Stelle bilden sich häufig Druckgeschwüre im Sitzbeinbereich.strongly restricted in movement People, such as quadriplegics, so paraplegics on all four limbs, are unable to relieve their sitting position on a regular basis. By the Constant pressure on a site often forms pressure sores in the ischial area.

Einkammerkissen verteilen den Druck gleichmäßig über eine größere Fläche, der Druck bleibt jedoch für den ganzen Bereich konstant.Einkammerkissen distribute the pressure evenly over one larger area, the However, pressure remains for the whole area constant.

Die im Schutzanspruch 1 angegebene Erfindung erreicht durch das regelmäßige, kurzzeitige Aufpumpen und Ablassen der Luftkammer, dass bei langem Sitzen, der permanente statische Druck auf eine Stelle vermieden wird und somit die Gefahr von Druckgeschwüren erheblich verringert wird.The in protection claim 1 invention achieved by the regular, short-term inflation and deflating the air chamber, that during long sitting, the permanent Static pressure on a body is avoided and thus the danger of pressure sores is significantly reduced.

Ein Ausführungsbeispiel der Erfindung wird anhand der 1 und 2 erläutertAn embodiment of the invention will be described with reference to 1 and 2 explained

1 zeigt die einzelnen Komponenten und die pneumatischen und elektrischen Verbindungen zwischen Ihnen. 1 shows the individual components and the pneumatic and electrical connections between them.

2 zeigt die physikalische Anordnung der Komponenten. 2 shows the physical arrangement of the components.

Das pneumatische Sitzkissen (1) ist über einen Schlauch (2) mit der Elektro-Pneumatischen Einheit (3) verbunden.The pneumatic seat cushion ( 1 ) is via a hose ( 2 ) with the electro-pneumatic unit ( 3 ) connected.

In dieser wird der Druck des Kissens über einen Druckverteiler (4) und über kurze Schläuche (5) mit einem elektronischen Drucksensor (6), einer Membran-Luftpumpe (7) und einem elektronischen Ablassventil (8) verbunden.In this, the pressure of the pad via a pressure distributor ( 4 ) and over short tubes ( 5 ) with an electronic pressure sensor ( 6 ), a membrane air pump ( 7 ) and an electronic drain valve ( 8th ) connected.

Die Pumpe und das Ablassventil werden mittels Treibern (9) über ein Kabel (10) von dem Steuergerät (11) ein- bzw. ausgeschaltet. Der Drucksensor liefert dem Steuergerät eine Spannung, die dem aktuellen Druck im Sitzkissen entspricht.The pump and the drain valve are controlled by means of drivers ( 9 ) via a cable ( 10 ) from the controller ( 11 ) on or off. The pressure sensor provides the control unit with a voltage that corresponds to the current pressure in the seat cushion.

Ein aufladbarer Akku (12) liefert die nötige Spannung für die Treiber und das Steuergerät. Das Steuergerät besteht im wesentlichen aus einem Mikroprozessor (13) und einem einstellbaren Potentiometer (14), mit dem der korrekte Normaldruck des Kissens eingestellt werden kann.A rechargeable battery ( 12 ) supplies the necessary voltage for the drivers and the control unit. The control unit consists essentially of a microprocessor ( 13 ) and an adjustable potentiometer ( 14 ) with which the correct normal pressure of the pad can be adjusted.

Der Mikroprozessor ist steckbar und somit leicht austauschbar. Dadurch können alternativ Mikroprozessoren mit unterschiedlichen Programmabläufen, die den individuellen Bedürfnissen des Behinderten angepasst werden können, eingesetzt werden.Of the Microprocessor is pluggable and thus easily replaceable. Thereby can alternatively microprocessors with different program sequences, the the individual needs be adapted to the disabled.

Ablauf des Standardprogramms:Expiration of the standard program:

Nach dem Einschalten des Mikroprozessors wird das Kissen auf einem Normaldruck gehalten. Dabei wird die Spannung des Drucksensors mit der des Potentiometers verglichen. Ist der Druck zu hoch, wird kurz das Ablassventil geöffnet, danach wird wieder gemessen.To turning on the microprocessor, the pad is at a normal pressure held. The voltage of the pressure sensor with that of the potentiometer compared. If the pressure is too high, the drain valve is opened briefly, then is measured again.

Ist der Druck zu gering wird die Pumpe für wenige Sekunden gestartet und wieder gemessen.is the pressure is too low, the pump is started for a few seconds and measured again.

Nach 20 Minuten wird durch Starten der Pumpe der Druck im Kissen erhöht.To 20 minutes, the pressure in the cushion is increased by starting the pump.

Ist der Maximaldruck erreicht, wird wieder auf Normaldruck abgelassen. Das wiederholt sich 3 mal hintereinander.is the maximum pressure is reached, is released again to normal pressure. This is repeated 3 times in a row.

Danach beginnt alles von vorn, also 20 Minuten halten des Normaldrucks usw..After that starts all over again, so keep 20 minutes of normal pressure etc..
