Abstract

An assembly-monitoring device for the drip detector on the drip chamber of an infusion device comprising a second photoelectric section in addition to the drip-recording photoelectric section, the second section scanning the contours of the drip chamber.

Description

Montageüberwachungseinrichtung des- Tropfendetektors an derAssembly monitoring device of the drop detector on the

Tropfenkammer eines Infusionsgerätes Bei Infusionsregelgeräten, insbesondere bei Schwerkraftinfusionsreglern, wird in aller Regel die in der Tropfenkammer fallende Tropfenfolge als Ist für die Regelung des Solls benutzt. Dies ist unabhängig davon, ob es sich um einen Nachlaufregler mit kontinuierlichem Fluß oder um ein intermettierendes Gerät, das die einzelnen Tropfen durchlaufen läßt, handelt. Aus dieser Prämisse ist evident, daß die Montage bzw. das richtige Anklemmen des Tropfendetektors an die Tropfenkammer von eminenter Bedeutung sind. Eine nicht erfolgte oder. nicht korrekt durchgeführte Montage des Tropfendetektors verursacht durch die Nicht-Erkennung der fallenden Tropfen fast immer den gefürchteten Freifluß (engl.: run away), der eine Stoß- bzw. Oberdosierung der medikamentösen Infusionslösung zur Folge hat, verbunden mit größter Gefahr für den Patienten, insbesondere im Falle hochwirksamer Arzneien wie z.B. Dopamin oder Nitroprussate.Droplet chamber of an infusion device In infusion control devices, in particular in the case of gravity infusion regulators, the one falling in the droplet chamber is generally used Droplet sequence used as actual for regulating the target. This is independent of whether it is a follower with continuous flow or an intermittent one Device that lets the individual drops run through, acts. From this premise it is evident that the assembly or the correct connection of the drop detector to the drop chambers are of eminent importance. A failed or. not Correct installation of the drop detector caused by non-detection of the falling drops almost always the dreaded free flow (English: run away), the results in a burst or overdosing of the medicated infusion solution, associated with the greatest danger to the patient, especially in the case of highly effective Medicines such as dopamine or nitroprussate.

Ziel dieser Erfindung ist das Schaffen einer sicheren einfachen und preiswerten Einrichtung, die das Nicht- oder Falschmontieren des Tropfendetektors der elektronischen Steuerung des Gerätes meldet und eventuell den Start unterbindet sowie einen Alarm auslöst.The aim of this invention is to provide a safe and simple inexpensive device that prevents the non-mounting or incorrect mounting of the drop detector reports to the electronic control of the device and possibly prevents the start as well as triggering an alarm.

In Fig. 1 ist eine mögliche Ausführung dargestellt. Zusätzlich zu der an sich belcannten tropfenerfassenden photoelektrischen Strecke (1,2), die üblicherweise in einem kleinen Gehäuse (3) untergebracht ist, wird eine zweite photoelektrische Strecke (4,5; die die Kontouren der Tropfenkammer (6) abtastet, so angeordnet, daß hauptsächlich die Peripherie der Tropfenkammer abgetastet wird. Letzteres ist nötig, weil ein nicht vollständig eingeschobener Tropfendetektor zur Folge haben kann, daß die Achse (7) der photoelektrischen Strecke nicht mit der der fallenden Tropfen (.#) koinzidiert. Da die Gestaltung der Tropfenkammer verschiedenartig istD kann es erforderlich sein wie in Fig. 3 dargestellt, daß, die zusätzliche photoelektrische Strecke unterhalb der Tropfenaötaststrecke angeordnet werden soll.In Fig. 1 a possible embodiment is shown. In addition to the per se belcanned drop-detecting photoelectric path (1,2), which is usually is housed in a small housing (3), a second photoelectric Distance (4,5; which scans the contours of the drop chamber (6), arranged so that mainly the periphery of the drop chamber is scanned. The latter is necessary because a drop detector that is not fully inserted can result in that the axis (7) of the photoelectric path does not coincide with that of the falling drops (. #) coincides. Since the design of the drop chamber is differentD can it may be necessary, as shown in FIG. 3, that the additional photoelectric Section is to be arranged below the droplet section.

In Fig. 4 ist eine universelle Ausführung dargestellt, die zwei zusätzliche photoel ektri sche Strecken aufweist, damit mit einem einzigen Tropfendetektorgehäuse (3) mindestens zwei Tropfenkammerformen erfaßt werden können.In Fig. 4, a universal design is shown, the two additional Photoel ektri cal routes, thus with a single drop detector housing (3) at least two droplet chamber shapes can be detected.
