Definitions
- the invention relates to a centrifuge for centrifuging blood with an insert cup, into which a blood bag can be inserted, which is connected to at least one other blood bag within the centrifuge via connecting tubes, and with a displacement body which bears against the insert cup and which has the volume of the insert cup can change.
- the insert cup is designed there as a one-piece container, the blood bag being at least partially inserted into the insert cup and projecting connection or supply tubes upward from the blood bag.
- FR-A-2 593 413 describes a clip for closing the upper end of a blood bag, which consists of two elongated clip halves exist, which are pivotally connected at one end via a film hinge and which can be releasably closed at the other end via a latch with barbs.
- the object of the invention is to further develop the insert cup so that it is easier and more reliable to operate at low manufacturing costs.
- the insert cup consists of two pivotable, longitudinally connected shell halves, each of which has a flange plate formed in the upper region, and that on the top of the shell halves there is a holder for the blood bag to be inserted between these shell halves is arranged.
- the blood bag can be inserted and is attached with its corresponding attachment tabs to the holder formed on the shell halves.
- This holder does not necessarily have to be designed as a plug holder, but it can be a simple clamp holder or some other guide which prevents the hoses from being kinked and breaking during the centrifuging process.
- the further design of the insert cup or the shell parts results from the subclaims.
- the insert cup 1 according to FIGS. 1 to 5 consists of two shell halves 2, 3 which are connected to one another in an articulated manner via a so-called film hinge 4.
- a film hinge instead of using a film hinge, other pivotable fastenings or articulated fastenings are of course also possible, such as molded joint parts, tapes that are riveted or glued, and the like. Swivel bearings more.
- a film hinge is preferred because such an insert cup is produced as an integral part by the injection molding process and in particular consists of an impact-resistant, wear-resistant plastic material.
- the insert cup has an interior 5, into which the blood bag is then inserted.
- Each shell half 2, 3 merges into a flange plate 6, 7 in its upper region, the flange plates lying opposite one another in the closed state (FIG. 2).
- Stud bolts 8 are formed on one flange plate 6, which are preferably made of the same material as the plastic material of the insert cup itself and are integrally connected to it.
- the stud bolts of one flange plate 6 engage in assigned elongated recesses 9 in the opposite flange plate.
- the design as slot-shaped recesses are preferred so that when the two shell halves are closed, the stud bolts 8 can be brought into engagement with these recesses without any particular friction and bumping against the edges of the recesses. Such an intervention is shown in FIG. 2, for example.
- a grip edge 10, 11 is formed on the top of each flange plate 6, 7, which makes it easier to grip the entire insert cup from above.
- Another advantage is that the handle edge 10, 11 increases the mechanical stability of the respective flange plate 6, 7 at the same time.
- reinforcing ribs 12, 13 are shown attached to the flange plates, which are supported on the top of the angled shell halves 2, 3. This improves the mechanical stability of the flange plates 6,7.
- Figure 5 also shows that one shell half 2 on its inner circumference, i.e. on its circumferential edge, has a circumferential lip 14 which protrudes beyond the clear opening 15 of the other shell half 3 (see FIG. 5).
- This protruding, circumferential lip 14 has the purpose of ensuring a precise centering of the two shell halves 2, 3 with respect to one another when these shell halves are closed.
- the profile cross section 16 of the respective insert cup 1 corresponds exactly to the clear profile of the centrifuge cup (metal centrifuge hanger) in which the insert cup is inserted.
- the insert cup thus fits positively and with relatively little play into the clear opening of a centrifuge suspension.
- the insert cup has a certain volume, which is generally matched exactly to the volume of the blood bag to be centrifuged.
- a hollow shell or cushion is inserted into the insert cup, which at least partially fills the volume of the insert cup.
- This hollow shell or cushion is placed in one half of the shell, and in the the other half of the shell, the blood bag is then inserted with a reduced volume.
- the hollow shell or the pad comes to lie on the blood bag with a reduced volume, so that the inside of the insert cup is completely filled; the blood bag is thus supported, is protected against collapse and the arrangement can thus be centrifuged reliably.
- the cushion can be glued directly into the insert cup and could e.g. B. be inflatable with air or contain a liquid.
- the cushion can be integrally connected in one piece with the material of the insert cup, so that the interior of the insert cup can be reduced or enlarged in accordance with the requirements.
Description
Die Erfindung betrifft eine Zentrifuge zum Zentrifugieren von Blut mit einem Einsatzbecher, in den ein Blutbeutel eingelegt werden kann, der über Verbindungsschläuche mit mindestens einem anderen Blutbeutel innerhalb der Zentrifuge in Verbindung steht, und mit einem an dem Einsatzbecher anliegenden Verdrängungskörper, der das Volumen des Einsatzbechers ändern kann.The invention relates to a centrifuge for centrifuging blood with an insert cup, into which a blood bag can be inserted, which is connected to at least one other blood bag within the centrifuge via connecting tubes, and with a displacement body which bears against the insert cup and which has the volume of the insert cup can change.
Eine derartige Zentrifuge beschreibt die DE-29 38 367-C2. Der Einsatzbecher ist dort als einstückiger Behälter ausgebildet, wobei der Blutbeutel zumindest teilweise in den Einsatzbecher eingeführt wird und dabei Verbindungs- oder Zuführungsschläuche nach oben hin von dem Blutbeutel abragen.Such a centrifuge is described in DE-29 38 367-C2. The insert cup is designed there as a one-piece container, the blood bag being at least partially inserted into the insert cup and projecting connection or supply tubes upward from the blood bag.
Bei dieser Art von Einsatzbechern konnte insbesondere ein praller Blutbeutel nur schwer eingeführt werden und weiterhin bestand die Gefahr, daß beim Zentrifugieren die vom Blutbeutel abragenden Schläuche abknickten und möglicherweise brechen konnten.With this type of insert cup, it was particularly difficult to insert a bulging blood bag, and there was still the risk that the tubes protruding from the blood bag would kink and possibly break during centrifugation.
Es ist weiterhin bekannt, Blutbeutel mit entsprechenden Halterungen lösbar an Einsatzbechern zu halten. Diese Halterungen sind aber konstruktiv relativ aufwendig und daher sind die Herstellungskosten eines derartigen Einsatzbechers relativ hoch.It is also known to detachably hold blood bags on insert cups with appropriate holders. However, these holders are structurally relatively complex and therefore the manufacturing costs of such an insert cup are relatively high.
Die FR-A-2 593 413 beschreibt eine Klammer zum Verschließen des oberen Endes eines Blutbeutels, die aus zwei länglichen Klammerhälften bestehen, die an einem Ende über ein Filmscharnier schwenkbar miteinander verbunden sind und die am anderen Ende über eine Rastnase mit Widerhaken lösbar geschlossen werden kann.FR-A-2 593 413 describes a clip for closing the upper end of a blood bag, which consists of two elongated clip halves exist, which are pivotally connected at one end via a film hinge and which can be releasably closed at the other end via a latch with barbs.
Ausgehend von einer Zentrifuge mit den eingangs genannten Merkmalen liegt der Erfindung die Aufgabe zugrunde, den Einsatzbecher so weiterzubilden, daß er bei geringen Herstellungskosten leichter und betriebssicherer zu bedienen ist.Starting from a centrifuge with the features mentioned in the introduction, the object of the invention is to further develop the insert cup so that it is easier and more reliable to operate at low manufacturing costs.
Zur Lösung der gestellten Aufgabe ist die Erfindung dadurch gekennzeichnet, daß der Einsatzbecher aus zwei schwenkbaren, längs miteinander verbundenen Schalenhälften besteht, welche im oberen Bereich jeweils eine Flanschplatte angeformt aufweisen, und daß an der Oberseite der Schalenhälften eine Halterung für den zwischen diesen Schalenhälften einzulegenden Blutbeutel angeordnet ist.To achieve the object, the invention is characterized in that the insert cup consists of two pivotable, longitudinally connected shell halves, each of which has a flange plate formed in the upper region, and that on the top of the shell halves there is a holder for the blood bag to be inserted between these shell halves is arranged.
Durch Aufklappen der Schalen werden sie Schalen somit geöffnet, der Blutbeutel kann eingelegt werden und wird mit seinen entsprechenden Ansatzlappen auf die an den Schalenhälften angeformte Halterung aufgesteckt.When the shells are opened, the shells are opened, the blood bag can be inserted and is attached with its corresponding attachment tabs to the holder formed on the shell halves.
Diese Halterung muß nicht unbedingt als Steckhalterung ausgebildet sein, sondern es kann eine einfache Klemmhalterung sein oder eine sonstige Führung die verhindert, daß die Schläuche abgeknickt werden und während des Zentrifugiervorganges brechen.
Die weitere Ausgestaltung des Einsatzbechers bzw. der Schalenteile ergibt sich aus den Unteransprüchen.This holder does not necessarily have to be designed as a plug holder, but it can be a simple clamp holder or some other guide which prevents the hoses from being kinked and breaking during the centrifuging process.
The further design of the insert cup or the shell parts results from the subclaims.
Die Erfindung wird nun anhand von Zeichnungen näher beschrieben.The invention will now be described with reference to drawings.

Der Einsatzbecher 1 gemäß Figur 1 bis 5 besteht aus zwei Schalenhälften 2,3, die gelenkig miteinander über ein sogenanntes Filmscharnier 4 verbunden sind. Statt der Verwendung eines Filmscharniers sind selbstverständlich auch andere schwenkbare Befestigungen oder gelenkige Befestigungen möglich, wie z.B. angespritzte Gelenkteile, Bänder, die angenietet oder geklebt sind, und dgl. Schwenklagerungen mehr.The
Aus Herstellungsgründen wird jedoch die Verwendung eines Filmscharniers bevorzugt, weil ein derartiger Einsatzbecher als integrales Teil im Spritzgruß-Verfahren hergestellt wird und insbesondere aus einem schlagzähen, verschleißfesten Kunststoffmaterial besteht.For manufacturing reasons, however, the use of a film hinge is preferred because such an insert cup is produced as an integral part by the injection molding process and in particular consists of an impact-resistant, wear-resistant plastic material.
Der Einsatzbecher weist hierbei einen Innenraum 5 auf, in den dann der Blutbeutel eingesteckt wird. Der Kunststoff, der bevorzugt verwendet wird, ist Arnitel (PBTP = Polybutylenterephthalat).The insert cup has an
Jede Schalenhälfte 2,3 geht in ihrem oberen Bereich in jeweils eine Flanschplatte 6,7 über, wobei im geschlossenen Zustand (Figur 2) die Flanschplatten einander gegenüberliegen.Each
An der einen Flanschplatte 6 sind hierbei Stehbolzen 8 angeformt, die bevorzugt aus dem gleichen Material bestehen wie das Kunststoffmaterial des Einsatzbechers selbst und werkstoffeinstückig mit diesem verbunden sind.Stud bolts 8 are formed on one
Statt derartiger Stehbolzen ist es jedoch auch möglich, Metallstehbolzen im Kunststoffmaterial einzuformen.Instead of such stud bolts, however, it is also possible to form metal stud bolts in the plastic material.
Im geschlossenen Zustand greifen die Stehbolzen der einen Flanschplatte 6 in zugeordnete langlochförmige Ausnehmungen 9 in der gegenüberliegenden Flanschplatte ein. Die Ausbildung als langlochförmige Ausnehmungen werden bevorzugt, damit beim Schließen der beiden Schalenhälften die Stehbolzen 8 ohne besondere Reibung und Anstoßen an den Rändern der Ausnehmungen in diese Ausnehmungen zum Eingriff bringbar sind.
Ein derartiger Eingriff ist beispielsweise in Figur 2 dargestellt.In the closed state, the stud bolts of one
Such an intervention is shown in FIG. 2, for example.
An der Oberseite jeder Flanschplatte 6,7 ist jeweils ein Griffrand 10,11 angeformt, der das Ergreifen des gesamten Einsatzbechers von oben erleichtert.A
Hierbei ist als weiterer Vorteil gegeben, daß der Griffrand 10,11 gleichzeitig die mechanische Stabilität der jeweiligen Flanschplatte 6,7 erhöht.Another advantage is that the
In einer Weiterbildung der vorliegenden Erfindung sind noch Verstärkungsrippen 12,13 an den Flanschplatten ansetzend gezeigt, die sich an der Oberseite der abgewinkelten Schalenhälften 2,3 abstützen. Damit ist die mechanische Stabilität der Flanschplatten 6,7 verbessert.In a further development of the present invention, reinforcing
Die Figur 5 zeigt ferner, daß die eine Schalenhälfte 2 an ihrem Innenumfang, d.h. an ihrem umlaufenden Rand, eine umlaufende Lippe 14 aufweist, die über die lichte Öffnung 15 der anderen Schalenhälfte 3 hervorsteht (vergleiche Figur 5). Diese hervorstehende, umlaufende Lippe 14 hat den Zweck, ein genaues Zentrieren der beiden Schalenhälften 2,3 zueinander beim Schließen dieser Schalenhälften zu gewährleisten.Figure 5 also shows that one
Dies erfolgt beim Schließen dadurch, daß zunächst die umlaufende Lippe 14 beim Aufeinandertreffen der Schalenhälften in den Innenraum der anderen Schalenhälfte eingreift und hierdurch die Schalenhälften zueinander zentriert werden und das Schließen vereinfacht wird.This takes place when closing in that first the
Im übrigen entspricht der Profilquerschnitt 16 des jeweiligen Einsatzbechers 1 genau dem lichten Profil des Zentrifugenbechers (metallenes Zentrifugengehänge), in welches der Einsatzbecher eingesetzt wird.Otherwise, the
Der Einsatzbecher paßt also formschlüssig und mit relativ geringem Spiel in die lichte Öffnung eines Zentrifugengehänges hinein.The insert cup thus fits positively and with relatively little play into the clear opening of a centrifuge suspension.
Weitere Vorteile der vorliegenden Erfindung sind also, daß man mit Verwendung eines neuerungsgemäßen Einsatzbechers die Blutbeutel nun bei geöffnetem Einsatzbecher in den Einsatzbecher hineinbringt, den Einsatzbecher dann sauber schließen kann und den so fertig geschlossenen Einsatzbecher in die lichte Öffnung des Zentrifugengehänges ohne weiteres einsetzen kann. Es entfallen daher die vorher beschriebenen Schwierigkeiten.Further advantages of the present invention are, therefore, that with the use of an insert cup according to the invention, the blood bags can now be inserted into the insert cup when the insert cup is open, the insert cup can then be closed properly and the insert cup thus closed can be inserted into the clear opening of the centrifuge hanger without further ado. The difficulties described above are therefore eliminated.
Vorstehend wurde beschrieben, daß der Einsatzbecher ein bestimmtes Volumen aufweist, welches in der Regel genau an das Volumen des zu zentrifugierenden Blutbeutels angepaßt ist.It has been described above that the insert cup has a certain volume, which is generally matched exactly to the volume of the blood bag to be centrifuged.
In bestimmten Anwendungsfällen kommt es jedoch vor, daß man Blutbeutel zentrifugieren will, deren Volumen wesentlich geringer ist als das Volumen des Einsatzbechers.In certain applications, however, it happens that you want to centrifuge blood bags, the volume of which is significantly less than the volume of the insert cup.
Hierbei ist es dann vorgesehen, daß in den Einsatzbecher hinein noch eine Hohlschale oder ein Polster eingelegt wird, welches mindestens teilweise das Volumen des Einsatzbechers ausfüllt. Diese Hohlschale oder dieses Polster wird in die eine Schalenhälfte hineingelegt, und in die andere Schalenhälfte wird dann der Blutbeutel mit verringertem Volumen eingelegt.It is then provided that a hollow shell or cushion is inserted into the insert cup, which at least partially fills the volume of the insert cup. This hollow shell or cushion is placed in one half of the shell, and in the the other half of the shell, the blood bag is then inserted with a reduced volume.
Nach dem Schließen dieses Einsatzbechers kommt damit die Hohlschale oder das Polster auf den Blutbeutel mit verringertem Volumen zu liegen, so daß damit der Einsatzbecher in seinem Inneren vollständig ausgefüllt ist; der Blutbeutel ist damit gestützt, wird vor dem Zusammenfallen geschützt und damit kann die Anordnung betriebssicher zentrifugiert werden.After closing this insert cup, the hollow shell or the pad comes to lie on the blood bag with a reduced volume, so that the inside of the insert cup is completely filled; the blood bag is thus supported, is protected against collapse and the arrangement can thus be centrifuged reliably.
Hierbei gibt es mehrere Ausführungsformen zur Verwendung eines derartigen Polsters in Einsatzbechern.There are several embodiments for using such a cushion in insert cups.
In einer ersten Ausführungsform kann das Polster unmittelbar in den Einsatzbecher eingeklebt sein und könnte z. B. mit Luft aufblasbar sein oder eine Flüssigkeit enthalten.In a first embodiment, the cushion can be glued directly into the insert cup and could e.g. B. be inflatable with air or contain a liquid.
In einer anderen Ausführungsform kann das Polster werkstoffeinstückig direkt mit dem Material des Einsatzbechers verbunden sein, so daß der Innenraum des Einsatzbechers entsprechend den Erfordernissen verkleinerbar oder vergrößerbar ist.In another embodiment, the cushion can be integrally connected in one piece with the material of the insert cup, so that the interior of the insert cup can be reduced or enlarged in accordance with the requirements.
Mit dem beschriebenen Einsatzbecher ist es also möglich, wesentlich betriebssicherer Blutbeutel verschiedenster Volumen zu zentrifugieren, wobei gleichzeitig die Schläuche und sonstigen Zuführteile sicher gehalten werden und vor dem Abknicken geschützt werden. Diese Schläuche und Zuführteile werden von den Flanschplatten mit eingeklemmt und damit erfolgt eine sichere Halterung.With the insert cup described, it is thus possible to centrifuge substantially reliable blood bags of various volumes, while at the same time holding the tubes and other supply parts securely and protecting them from kinking. These hoses and feed parts are also clamped in by the flange plates, thus ensuring secure mounting.
Wesentlich hierbei ist, daß mehrere Beutel in diesem Einsatzbecher aufgenommen werden können, wobei das Einsetzen dieser mehreren Beutel in den Einsatzbecher leicht erfolgt und immer nur dafür gesorgt werden muß, daß der Einsatzbecher zu schließen ist; die anderen Beutel sind in der Regel leer und können irgendwie zusammengefaltet in den Einsatzbecher zusammen mit dem zu zentrifugierenden, vollen Beutel gebracht werden.It is essential here that several bags can be accommodated in this insert cup, the insertion of these several bags in the insert cup is easy and only has to be ensured that the insert cup is closed; the other bags are usually empty and can be folded into the insert cup together with the full bag to be centrifuged.
Ein Hineinstopfen dieser Mehrfachanordnung bereits schon in das Zentrifugengehänge ergibt Schwierigkeiten, weil eben diese leeren Beutel zusammen mit dem gefüllten Beutel sonst nur schwierig unterzubringen sind.Plugging this multiple arrangement into the centrifuge hanger already gives rise to difficulties because these empty bags together with the filled bag are otherwise difficult to accommodate.
