Abstract
Zur Verbesserung der Hygiene bei Infusionen wird vorgeschlagen, das Einperlen der Luft in die starre oder halbstarre Infusionsvorlage zu verhindern, indem ein Element (Röhrchen) verwendet wird, welches die Luft getrennt von der Infusionsflüssigkeit zum Boden des Behälters führt. Ferner wird vorgeschlagen, die Querschnittsfläche des Infusionsbehälters geringer als derzeit üblich auszubilden, d. h. den Schlankheitsgrad zu erhöhen.To improve the hygiene of infusions, it is proposed to prevent the sparging of the air into the rigid or semi-rigid infusion template by using an element (tube) which directs the air separated from the infusion liquid to the bottom of the container. It is also proposed to make the cross-sectional area of the infusion container smaller than currently customary, d. H. to increase the degree of slimming.
Description
Die Erfindung betrifft eine Entnahmevorrichtung bzw. einen Spike, insbesondere zur Entnahme von Infusionsflüssigkeit aus einem starren oder halbstarren Behälter sowie die Gestaltung der Infusionsgefäße.The invention relates to a removal device or a spike, in particular for the removal of infusion fluid from a rigid or semi-rigid container and the design of the infusion vessels.
Stand der Technik: Bei Infusionen muss besonders darauf geachtet werden, dass keine Verunreinigungen (Aerosole, Bakterien, Viren) in die Venen gelangen. Bei starren und halbstarren Infusionsbehältern muss beim Ausfließen des Medikamentes darauf geachtet werden, dass die in das Infusionsgefäß einperlende Luft rein ist.
Problemlösung: Die Erfindung sieht vor, das Aufsteigen der Luft in der Infusionsflüssigkeit weitgehend zu verhindern, indem Mittel vorgesehen werden, welche die Luft beim Einströmen in das Infusionsgefäß getrennt von der Infusionsflüssigkeit halten (siehe Hauptanspruch) und die Luft so getrennt zum nach oben aufgehängten Boden des Infusionsgefäßes führen. Die Kontaktfläche Luft/Infusionslösung begrenzt sich dann lediglich auf die obere innere Querschnittsfläche des Infusionsgefäßes, bei einem Durchmesser von 10 cm also auf etwa 1/200 der obigen Kontaminationsfläche!Problem Solution: The invention provides to prevent the rising of the air in the infusion liquid largely by providing means which keep the air as it flows into the infusion vessel separate from the infusion liquid (see main claim) and the air separated so to the suspended bottom of the infusion vessel. The contact surface air / infusion solution is limited then only to the upper inner cross-sectional area of the infusion vessel, with a diameter of 10 cm so to about 1/200 of the above contamination surface!
