Description

Kühlgerät für Insulin zum stationären und beweglichen Betrieb.Insulin cooling device for stationary and mobile operation.

Die Erfindung betrifft ein Kühlgerät für Insulin zum stationären und beweglichen Betrieb.The invention relates to a cooling device for insulin for stationary and mobile operation.

Insulin in seiner gebräuchlichsten Form muß unter 15 °C gekühlt aufbewahrt werden. Dazu stehen nur handelsübliche Kühlschränke zur Verfügung mit großem Platzbedarf und einer begrenzten Mobilität.Insulin in its most common form must be kept refrigerated below 15 ° C. For this purpose, only commercially available refrigerators are available with a large space requirement and limited mobility.

Der Erfindung liegt die Aufgabe zugrunde, dem Diabetiker ein Kühlgerät in die Hand zu geben, um sein Insulin bei optimaler Temperatur zuhause und auf Reisen hygienisch aufzubewahren.The object of the invention is to provide the diabetic with a cooling device in order to keep his insulin hygienically at an optimal temperature at home and when traveling.

Die Aufgabe wird dadurch gelöst, daß das Kühlgerät neben der speziell für die Aufnahme von Insulinampullen dimensionierten Kühlzelle mit Kühlguthorde, das Kühlelement selbst, die Temperaturregelung und die elektronische Anpassung an das 220V Netz sowie an das 12V Bordnetz eines Kraftfahrzeuges enthält.The object is achieved in that the cooling device contains, in addition to the cooling cell with refrigerated goods rack specially dimensioned for receiving insulin ampoules, the cooling element itself, the temperature control and the electronic adaptation to the 220V network and to the 12V electrical system of a motor vehicle.

Die mit der Erfindung erzielten Vorteile bestehen darin, daß das Medikament nicht mit Lebensmitteln im Kühlschrank bei einer ziemlich undefinierten Temperatur aufbewahrt werden muß. Das Kühlgerät nimmt Ampullen aller europäischer Hersteller auf und bietet durch den Autobatteriebetrieb individuelle Bewegungsfreiheit.The advantages achieved by the invention are that the medication does not have to be kept in the refrigerator at a fairly undefined temperature with food. The cooling unit accepts ampoules from all European manufacturers and offers individual freedom of movement thanks to the car battery operation.

Die Zeichnung 1 zeigt die Kühlzelle mit der Kühlguthorde.Drawing 1 shows the cold room with the refrigerated goods tray.

Die Kühlzelle besteht aus einem Aluminiumhohlprofil mit den Innenmaßen 72x32x170 mm und einer Wandstärke von 4 mm. Ein Ende des Profils ist mit einem Aluminiumblech von 2mm Dicke verschlossen. An der linken Seite mittig ist ein Peltierelement mit Kühlblock angeschraubt. Das Peltierelement ist beidseitig mit je einem 10 mm starken Adapter versehen um die Kühlzelle durchgehend mit 20 mm dickem extrodiertem Hartschaum isolieren zu können. Die Unebenheiten zwischen Peltierelement und Isolierung sind mit PVC-Schaumstoff abgedichtet. Die Hartschaumisolierung ist innen und außen mit Alufolie als Wärme- und Feuchtigkeitssperrschicht belegt. Zwischen Aluminiumhohlprofil und Hartschaumisolierung ist ein Luftspalt von ca. 3 mm als zusätzliche Isolierschicht. Als Abstandshalter dienen selbstklebende Hartschaumstreifen. Die Luftspalte am offenen Ende zwischen Isolierung und Aluminiumhohlprofil sowie zwischen Isolierung und Kühlblock sind gegen eindringende Feuchte mit Silikon ausgespritzt.The cooling cell consists of an aluminum hollow profile with the internal dimensions 72x32x170 mm and a wall thickness of 4 mm. One end of the profile is closed with an aluminum sheet 2mm thick. A Peltier element with a cooling block is screwed onto the center left. The Peltier element is provided on both sides with a 10 mm adapter to insulate the cold room with 20 mm thick extruded hard foam. The bumps between the Peltier element and the insulation are sealed with PVC foam. The rigid foam insulation is covered on the inside and outside with aluminum foil as a heat and moisture barrier layer. There is an air gap of approx. 3 mm between the hollow aluminum profile and hard foam insulation as an additional insulating layer. Self-adhesive hard foam strips serve as spacers. The air gaps at the open end between the insulation and the aluminum hollow profile as well as between the insulation and the cooling block are sprayed with silicone against the ingress of moisture.

Die Kühlguthorde besteht aus einem quadratischen PVC-Hohlprofil (30x30 mm, 2 mm Dicke) mit 6 Bohrungen zu 24 mm. Diese dienen zur Aufnahme von 6 Insulinampullen (letzte Ampulle plus neue Packung mit 5 Ampullen). Die Abmessungen der Kühlzelle und der Kühlguthorde sind so gewählte daß Ampullen aller europäischen Hersteller verwendet werden können. An der Kühlguthorde befindet sich der Verschluß der Kühlzelle. Die Isolierung ist entsprechend. Der Luftspalt zwischen Kühlzelle und Verschluß wird mit PVC-Schaumstoff abgedichtet. Die Arretierung des Verschlußes erfolgt über ein umlaufendes Magnetband. Sie ist verstärkt mit 4 Dauermagneten an den Ecken des Verschlusses.The refrigerated goods tray consists of a square PVC hollow profile (30x30 mm, 2 mm thick) with 6 holes of 24 mm. These are used to hold 6 insulin ampoules (last ampoule plus new pack of 5 ampoules). The dimensions of the cold room and the refrigerated goods tray are selected so that ampoules from all European manufacturers can be used. The cold store lock is located on the refrigerated goods rack. The insulation is appropriate. The air gap between the cold room and the closure is sealed with PVC foam. The closure is locked using a circumferential magnetic tape. It is reinforced with 4 permanent magnets at the corners of the closure.

Zeichnung 2 zeigt das Prinzipschema des Kühlgerätes. Die elektronischen Baugruppen (Regler und Schaltnetzteil) sind im Fachhandel fertig bzw. als Bausatz erhältlich.Drawing 2 shows the basic diagram of the cooling device. The electronic modules (controller and switching power supply) are available from specialist dealers or are available as a kit.

Der Temperaturfühler des Reglers ist an der kalten Seite des Peltieralements am Adapter befestigt. Durch die Anordnung des Temperaturfühlers am Adapter wird die Temperatur in der Kühlzelle nie unter den eingestellten Wert absinken, aber aufgrund der relativ großen Massen auch nicht darüber liegen. Bei dieser Anordnung und einer Außentemperatur von 30 °C sowie einer Kühltemperatur von 10 °C wurde eine Temperaturkonstanz von ± 0,5 °C gemessen. Der maximale Kühlbereich des Peltierelements wird laut Hersteller mit bis zu ca. 60 °C niedriger als die Außentemperatur angegeben. Schaltnetzteil, Regler und Ventilator arbeiten mit 12V Gleichspannung. Die Versorgung erfolgt über den eingebauten Transformator und die beiden 'Gleichrichter oder eine Autobatterie. Die Schnittstelle Energieversorgungsteil - Funktionsteil ist steckbar und somit die Art der Energieversorgung einfach zu wechseln. Die Betriebszustände "betriebsbereit" und "Kühlung ein - aus" werden durch Leuchtdioden angezeigt.The temperature sensor of the controller is attached to the adapter on the cold side of the Peltier element. By arranging the temperature sensor on the adapter, the temperature in the cold room will never drop below the set value, but will not be above it due to the relatively large masses. With this arrangement and an outside temperature of 30 ° C and a cooling temperature of 10 ° C, a constant temperature of ± 0.5 ° C was measured. According to the manufacturer, the maximum cooling range of the Peltier element is specified as up to approx. 60 ° C lower than the outside temperature. Switching power supply, controller and fan work with 12V DC voltage. The supply takes place via the built-in transformer and the two 'rectifiers or a car battery. The interface between the energy supply section and the functional section can be plugged in, making it easy to change the type of energy supply. The operating states "ready for operation" and "cooling on - off" are indicated by LEDs.

Ergänzende Erläuterungen:Additional explanations:

Die Anordnung der Ampullen in einer Reihe hat den Vorteil, daß der Kälte-Wärmekontakt von Kühlgut zu Kühlzelle optimal ist. Zur Entnahme der "Gebrauchsampulle" muß das Kühlgerät nur einen Spalt geöffnet werden.The arrangement of the ampoules in a row has the advantage that the cold-heat contact from the refrigerated goods to the cold room is optimal. To remove the "ampoule", the cooling device only has to be opened slightly.

Die beidseitige Belegung der Isolierung mit einer Feuchtigkeitssperrschicht schließt Kälteverluste und Verrottung des Isoliermaterials aufgrund von Feuchtigkeitskondensation völlig aus. Die Reflektion erhöht die Isolationswirkung.The double-sided covering of the insulation with a moisture barrier layer completely prevents cold loss and rotting of the insulation material due to moisture condensation. The reflection increases the insulating effect.
