Description
Die Erfindung geht aus von einer Vorrichtung zur Blutwäsche lebender Menschen oder Tiere, umfassend ein durch eine Filterschicht mit einer Anströmfläche in zwei Kammern unterteiltes Gehäuse, von denen die an die Anströmfläche angrenzende Kammer das zu waschende Blut enthält, welches parallel zu der Anströmfläche über die Filterschicht hinwegführbar ist, wobei zumindest die die Anströmfläche benetzenden Bestandteile des Blutes durch einen an dem Gehäuse angeordneten, motorischen Schwingungserreger in eine periodisch schwingende Bewegung versetzbar sind, wobei der Schwingungserreger einen Bestandteil einer das Gehäuse aufnehmenden Stützvorrichtung bildet.The invention relates to a device for blood washing of living people or animals, comprising one by one Filter layer with an inflow surface in two chambers subdivided housing, of which the to the inflow surface adjacent chamber contains the blood to be washed, which is parallel to the inflow surface over the filter layer can be led away, at least the flow surface wetting components of the blood by one on the Motor vibration exciter arranged in the housing a periodically oscillating movement can be offset, wherein the vibration exciter is part of the Housing receiving support forms.
Eine solche Vorrichtung ist aus der EP 0 388 546 A1 bekannt. Der Schwingungserreger ist in einer Stützvorrichtung enthalten, die das Gehäuse aufnimmt und mit diesem starr verbunden ist. Die Vorrichtung hat keinerlei Bekanntheitsgrad bei der praktischen Durchführung der Blutwäsche lebender Menschen oder Tiere erlangt.Such a device is known from EP 0 388 546 A1. The vibration exciter is in a support device included, which receives the housing and rigid with this connected is. The device has no level of awareness in the practical implementation of blood washing more live Acquired humans or animals.
Es ist hingegen üblich, zur Blutwäsche lebender Menschen oder Tiere eine Vorrichtung zu verwenden, bei der die Filterschicht durch die Wandung von Kunststoffrohren gebildet wird, die innenseitig von dem zu reinigenden Blut und außenseitig von einer Spülflüssigkeit umströmt sind. Der eigentliche Blutreinigungsvorgang beruht auf der Ausnutzung von Filtrations- und Konvektionsvorgängen sowie auf der Ausnutzung osmotischer Effekte. Die Leistungsfähigkeit des bekannten Querstromfilters ist wenig befriedigend. Der Durchsatz ist am Beginn der Benutzung groß und nimmt durch die Ausbildung von Sekundärmembranen auf der Anströmfläche der Kunststoffrohre exponentiell ab. Das bekannte Querstromfilter benötigt außerdem eine vergleichsweise große Anlaufzeitspanne, bis die volle Leistungsfähigkeit nach Inbetriebnahme erreicht ist. Durch die sich während der Benutzung auf der Anströmfläche ablagernden Blutbestandteile wird die Größe der Filterschicht reduziert und der Porendurchmesser verringert. Eine ausreichende Reinigung ist nicht möglich. Das bekannte Querstromfilter kann dadurch nur einmal verwendet werden.However, it is common for blood washing of living people or animals to use a device in which the Filter layer formed by the wall of plastic pipes which is inside of the blood to be purified and are flushed with a rinsing liquid on the outside. Of the actual blood purification process is based on exploitation of filtration and convection processes as well as on the Exploitation of osmotic effects. The performance of the known cross-flow filter is unsatisfactory. Of the Throughput is large and slow at the beginning of use through the formation of secondary membranes on the The flow area of the plastic pipes exponentially. The known cross-flow filter also requires one comparatively large start-up period until the full Efficiency is achieved after commissioning. Through the during use on the inflow surface Deposited blood components become the size of the filter layer reduced and the pore diameter reduced. A adequate cleaning is not possible. The known Cross-flow filters can only be used once.
Aus der DE-OS 36 05 065 ist eine Separationsvorrichtung für Suspensionen bekannt, welche Zellen von Zellkulturen enthalten. Ein Hinweis auf die Verwendbarkeit bei der Blutwäsche lebender Menschen oder Tiere ist der Druckschrift nicht entnehmbar.DE-OS 36 05 065 is a separation device for Suspensions known which cells are from cell cultures contain. A note on the usability at Blood washing of living people or animals is the document not removable.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art derart weiter zu entwickeln, daß sich bei Verwendung üblicher Querstromfilter eine verbesserte Leistungsfähigkeit und eine Verkürzung der Anlaufdauer nach der Inbetriebnahme ergibt.The invention has for its object a device of the type mentioned in such a way to further develop that when using conventional cross-flow filters improved performance and a reduction in Start-up time after commissioning results.
Diese Aufgabe wird mit dem Gegenstand des Anspruchs 1 gelöst.This task is the subject of Claim 1 solved.
Danach ist es vorgesehen, daß das Gehäuse mittels einer Klemm- oder Schraubverbindung lösbar an der Stützvorrichtung festgelegt ist. Die Erfindung geht aus von der Erkenntnis, daß bei der Blutwäsche lebender Menschen und Tiere üblicherweise Querstromfilter zur Anwendung gelangen, die von bestimmter Form und Größe sind und die nur ein einziges Mal verwendet werden. Derartige Querstromfilter können sehr leicht im Sinn der vorliegenden Erfindung benutzt werden. Das Gehäuse muß dafür mittels einer Klemm- oder Schraubverbindung lösbar an der Stützvorrichtung festgelegt sein. After that it is intended that the housing by means of a clamp or Screw connection releasably fixed to the support device is. The invention is based on the knowledge that the Blood washing of living people and animals usually Cross-flow filters are used by certain Shape and size are and are used only once will. Such cross-flow filters can be very easily in mind of the present invention. The housing must be done by means of a clamp or screw connection be releasably attached to the support device.
Die während der bestimmungsgemäßen Verwendung eingeleitete, periodisch schwingende Bewegung begünstigt sowohl den Benetzungs- als auch den Filtrationsvorgang.The during the intended use initiated, periodically oscillating movement favors both the wetting and the filtration process.
Die schwingende Bewegung kann hin- und hergehender, kreisförmiger oder taumelnder Art sein. Insbesondere im letztgenannten Fall ergibt sich eine deutliche Steigerung der Leistungsfähigkeit.The swinging motion can be reciprocating, circular or tumbling. Especially in the latter case results in a significant increase in Performance.
Eine weitere Steigerung der Leistungsfähigkeit läßt sich erzielen, wenn sich die Anströmfläche vor und während der Durchführung des Filtrationsvorganges in einer im wesentlichen senkrechten Lage befindet. Der Anströmfläche anhaftende Gasbestandteile und schädliche Rückstände aus der Produktion, die das Erreichen der vollen Leistungsfähigkeit nach der Inbetriebnahme verzögern können, werden hierdurch besonders zügig ausgespült.A further increase in performance can be achieve if the inflow surface before and during the Carrying out the filtration process in one essentially vertical position. The inflow surface adhering gas components and harmful residues of production, which is achieving full performance can be delayed after commissioning thereby rinsed particularly quickly.
Die Unteransprüche geben Ausführungsarten der Erfindung an.The subclaims indicate embodiments of the invention.
Als zweckmäßig hat es sich erwiesen, wenn der Schwingungserreger mit einem elektromotorischen Antrieb versehen ist, beispielsweise einem Tauch- oder Drehspulenantrieb. Die Verwendung elektromotorischer Antriebe, die zumindest einen Piezokristall enthalten, wird im Rahmen der vorliegenden Erfindung bevorzugt. Sie zeichnen sich durch eine geringe Baugröße bei hoher Leistungsdichte aus sowie durch die Möglichkeit einer besonders feinfühligen Ansteuerung.It has proven to be useful if the vibration exciter provided with an electric motor drive is, for example, a moving or moving coil drive. The Use of electromotive drives, at least contain a piezo crystal, is within the scope of the present Invention preferred. They are characterized by a small size with high power density the possibility of a particularly sensitive control.
Der Schwingungserreger ist zweckmäßig mit einer variierbaren Frequenz betreibbar, um resonanzüberhöhte Schwingungsausschläge zu vermeiden und eine optimale Filterwirkung zu erzielen. Eine Verbesserung in dieser Hinsicht läßt sich erreichen, wenn der Schwingungserreger alternativ oder zusätzlich mit einer variierbaren Amplitude betreibbar ist.The vibration exciter is useful with a variable Frequency operable to avoid resonant vibrations to avoid and an optimal filter effect to achieve. An improvement in this regard leaves reach themselves if the vibration exciter alternatively or can also be operated with a variable amplitude.
Das erfindungsgemäße Querstromfilter eignet sich besonders gut für die Blutwäsche lebender Menschen oder Tiere. Ein wesentlicher Vorteil darin, daß die volle Leistungsfähigkeit nach Inbetriebnahme schnell erreicht wird und über die gesamte Benutzungsdauer nahezu unveränderlich erhalten bleibt. Darüber hinaus entstehen keine fest anhaftenden Anbackungen auf der Anströmfläche der Filterschicht. Eine Reinigung und Wiederverwendung sind dadurch problemlos möglich.The cross-flow filter according to the invention is particularly suitable good for the blood washing of living people or animals. On significant advantage in that the full performance is reached quickly after commissioning and via the preserved the entire service life almost unchangeable remains. In addition, there are no firmly adhering Caking on the inflow surface of the filter layer. A This makes cleaning and reuse easy possible.
Ein Ausführungsbeispiel der Erfindung ist im folgenden an Hand der Zeichnung, die einen Längsschnitt dargestellt, beschrieben.An embodiment of the invention is as follows based on the drawing, the one Longitudinal section shown, described.
Die Vorrichtung umfaßt ein Gehäuse 1 aus Kunststoff, welches für die Blutwäsche lebender Menschen oder Tiere bestimmt ist.The device comprises a housing 1 made of plastic, which is intended for the blood washing of living people or animals.
Das Gehäuse 1 ist im wesentlichen hohlzylindrisch gestaltet. Es umschließt im Bereich der Stirnseiten die Kammern 3, welche untereinander durch Kunststoffrohre verbunden sind. Das im Bereich der Einlauföffnung 9 in die untere Kammer 3 eintretende, zu reinigende Blut durchströmt die gebündelt vorliegenden Kunststoffrohre und gelangt anschließend in die obere Kammer 3, bevor es das Gehäuse 1 über die Austrittsöffnung 10 verläßt.The housing 1 is essentially hollow cylindrical. It encloses the chambers 3 in the region of the end faces, which are connected to one another by plastic pipes. The blood to be cleaned that enters the lower chamber 3 in the area of the inlet opening 9 flows through the bundled plastic tubes and then reaches the upper chamber 3 before it leaves the housing 1 via the outlet opening 10 .
In der Zwischenzone zwischen den Kammern 3 sind die Kunststoffrohre in einer Kammer 4 aufgenommen, die in Richtung der eingetragenen Pfeile von einer Spülflüssigkeit durchströmbar ist. Diese tritt in die Kammer 4 durch die Eintrittsöffnung 11 ein und verläßt die Kammer 4 über die Austrittsöffnung 12. Die Kammern 3 und 4 sind voneinander durch die die Kunststoffrohre bildenden, hohlzylindrisch gestalteten Filterschichten 2 getrennt. Ein Stoffaustausch zwischen den Kammern 3 und 4 kann nur durch die Filterschichten 2 hindurch erfolgen.In the intermediate zone between the chambers 3 , the plastic pipes are accommodated in a chamber 4 through which a flushing liquid can flow in the direction of the arrows. This enters the chamber 4 through the inlet opening 11 and leaves the chamber 4 via the outlet opening 12 . The chambers 3 and 4 are separated from one another by the hollow-cylindrical filter layers 2 forming the plastic tubes. A mass transfer between the chambers 3 and 4 can only take place through the filter layers 2 .
Das Gehäuse 1 ist an einer Stützvorrichtung 7 mittels einer elastischen Klammereinrichtung 13 lösbar festgelegt und durch einen elektromotorischen Tauchspulenantrieb 8 in eine in senkrechter Richtung periodisch hin- und herschwingende Bewegung versetzbar. Der Magnetkern der Tauschspule ist dazu auf einer Druckfeder abgestützt und gegen deren Kraft durch die Tauchspule bewegbar. Die Frequenz und Amplitude der schwingenden Bewegung sind durch eine in der Zeichnung nicht gezeigte Einrichtung zur elektrischen Aktivierung der Tauchspule veränderbar. Sie lassen sich durch einfach durchzuführende Versuche schnell auf einen Wert einstellen, bei dem sich eine optimale Filterleistung unter Vermeidung einer Schädigung des Blutes ergibt.The housing 1 is detachably fixed to a support device 7 by means of an elastic clamp device 13 and can be set in a periodically oscillating movement back and forth by an electromotive plunger coil drive 8 . The magnetic core of the exchange coil is supported on a compression spring and can be moved by the plunger against its force. The frequency and amplitude of the oscillating movement can be changed by a device for the electrical activation of the moving coil, not shown in the drawing. They can be quickly set to a value by means of simple experiments, at which an optimal filter performance results, while avoiding damage to the blood.
