Abstract
Mittel zur Behandlung von Verätzungen mit Fluorwasserstoffsäure, hergestellt durch Vermischen von gleichen Volumina von kristallinem Magnesiumsulfat und Glycerin und anschließendes Erhitzen unter Umrühren bis nahe 290°C.Agent for the treatment of chemical burns with hydrofluoric acid, prepared by mixing equal volumes of crystalline magnesium sulphate and glycerol and then heating with stirring to near 290 ° C.
Description
Die Erfindung betrifft ein Mittel zur Behandlung von Verätzungen mit Fluorwasserstoffsäure.The The invention relates to an agent for the treatment of chemical burns with hydrofluoric acid.
Anwendungsgebiet ist der Arbeitsschutz beim Umgang mit Fluorwasserstoffsäure im Labor, bei TUL-Prozessen und in der chemischen Industrie.field of use is occupational safety when handling hydrofluoric acid in the laboratory, at TUL processes and in the chemical industry.
In der Silikatanalytik als Aufschlussmittel und bei Fertigungsprozessen in der Mikroelektronik ist Fluorwasserstoffsäure (40%, 70% und 100%), im weiteren HF, unverzichtbar. Beim Umgang damit kann es zu Hautkontakt kommen. Die Folge sind äußert schmerzhafte Verätzungen, die wegen der hohen Diffusionsgeschwindigkeit der Fluoridionen auch tiefer in das Hautgewebe reichen können und nur langsam abheilen.In Silicate analysis as a digestion agent and in manufacturing processes in microelectronics is hydrofluoric acid (40%, 70% and 100%), in the further HF, indispensable. Dealing with it may cause skin contact. The episode are extremely painful Acid burns, because of the high diffusion rate of the fluoride ions also deeper can reach into the skin tissue and only heal slowly.
Das klassische Mittel zur Behandlung solcher Verätzungen (s. Lehrbücher, Erste-Hilfe-Instruktion) ist eine durch Verrühren von Magnesiumoxid mit Glycerin hergestellte Paste, mit der die betroffenen Stellen zu bestreichen sind. Die Fluoridionen werden vom Magnesiumoxid zu ebenfalls unlöslichem und inertem Magnesiumfluorid gebunden. Diese Behandlungsmethode ist uneffektiv: Es werden nur die Fluoridionen gebunden, die noch nicht in das Hautgewebe eingedrungen sind. Tiefer gehende Gewebeschäden (bis zur Nekrose) sind, besonders wenn nach der Benetzung mit HF bereits einige Minuten angedauert hat, nicht mehr abzuwenden. Selbst Hautärzte stehen diesem Problem noch immer ratlos gegenüber.The classical means of treating such burns (see textbooks, First Aid Instruction) is one by stirring made of magnesium oxide with glycerin paste, with the affected areas to brush. The fluoride ions are added by the magnesium oxide also insoluble and inert magnesium fluoride bonded. This treatment method is ineffective: Only the fluoride ions are bound have not penetrated into the skin tissue. Lowering tissue damage (to to necrosis), especially after wetting with HF already persisted for a few minutes, no longer averting. Even dermatologists are standing still baffled by this problem.
Ziel der Erfindung ist es, ein effektives Mittel zur Behandlung von Verätzungen mit Fluorwasserstoffsäure zu entwickeln.aim The invention is an effective agent for the treatment of chemical burns with hydrofluoric acid to develop.
Diese Aufgabe wird gemäß den Ansprüchen gelöst.These Task is solved according to the claims.
Vorgeschlagen wird die Behandlung der mit HF kontaminierten Hautstellen mit einem Mittel, das durch Mischen gleicher Volumina kristallinem Magnesiumsulfat und Glycerin und Erhitzen bis nahe 290°C hergestellt wird.proposed The treatment of HF contaminated skin with a Agent, by mixing equal volumes of crystalline magnesium sulfate and glycerol and heating to near 290 ° C.
Nach dem Erkalten wird eine hydrophile Masse mit vaselineartiger Konsistenz erhalten, in der Magnesium in ionischer Bindung vorliegt. Beim Auftragen dieser Masse auf die Haut dringen die Magnesiumionen ebenfalls in das Gewebe ein. Wegen des deutlich geringeren Ionenradius der Magnesiumionen gegenüber den Fluoridionen, ist ihre Diffusionsgeschwindigkeit entsprechend größer. So werden auch bereits in das Gewebe eingedrungene Fluoridionen noch erreicht und gebunden. Die Gewebeschädigung bleibt aus oder wird vermindert, je nachdem, wie viel Zeit bis zum Aufbringen des Mittels vergangen ist.To cooling is a hydrophilic mass with Vaseline-like consistency obtained in which magnesium is in ionic bond. When applying The magnesium ions also penetrate this mass on the skin the tissue. Because of the much lower ionic radius of the magnesium ions across from the fluoride ions, their diffusion rate is corresponding greater. So are also already penetrated into the tissue fluoride ions reached and bound. The tissue damage remains or becomes diminished, depending on how much time to apply the agent has passed.
Eigene Erfahrung mit dem beschriebenen Mittel hat gezeigt, dass rechtzeitig behandelte mit HF benetzte Hautpartien unversehrt bleiben.own Experience with the means described has shown in good time treated with HF wetted skin remains intact.
