Abstract

The extra-safe clinical thermometer is designed to reduce the dangerous consequences of an escape of Mercury due to the fracture of the thermometer glass. The protection for the thermometer is provided by a plastic coating which totally encloses the thermometer's glass walls. The accu racy is not affected but the measurement time is slightly extended. This small disadvantage is offset by the increased safety of the instrument. The plastic coating is not uniform, but is thickened at strategic points requiring greater protection. Should the glass become fractured, the glass fragments and the Mercury filling are safely contained within the plastic envelope.

Description

Kunststoffüberzogenes Fieberhtermometer zur VerhinderungPlastic covered thermometer for prevention

von Quecksilberaustritt bei Glasbruch.of mercury leakage in the event of glass breakage.

Beschreibung Gegenstand vorliegender Patentanmeldung ist ein mit einer geschlossenen Kunststoffhülle ummanteltes Fieberthermometer. Bricht der Glaskörper des Fieberthermometers, so hält die nicht zerbrechliche Kunststoffhülle den Glaskörper derart, daß Quecksilber nacht austreten und später unkontrolliert veruampfen kann.Description The subject of the present patent application is a with a closed plastic cover covered clinical thermometer. Breaks the vitreous humor of the clinical thermometer, the non-breakable plastic cover holds the glass body in such a way that mercury can escape at night and later evaporate in an uncontrolled manner.

Fieberthermometer müssen aus den bekannten Gründen mit Quecksilberfüllung versehen werden. Zerbrechen solche Thermometer (was im Krankenhaus eine tägliche Erscheinung ist), so ist meist nicht za verhindern, daß der Quecksilberinhalt oder doch ein Teil davon, austritt, und sich in kleinste Kügelchen verteilt. Diese können meist garnicht oder nur zum 2eil eingesammelt und entfernt werden. Das im Raum verbliebene Quecksilber verdampft bereits bei Zimmertemperatur geruchlos und wird mit der Luft vermischt eingeatmet. Dies kann je nach Konzentration und Dauer zu schweren Vergiftungen führen.For known reasons, clinical thermometers must be filled with mercury be provided. Break such thermometers (which is a daily in hospital Appearance), it is usually not possible to prevent the mercury content or but part of it emerges and distributes itself into tiny spheres. these can usually not at all or only collected and removed for 2eil. The one left in the room Mercury evaporates odorless even at room temperature and becomes odorless with the air inhaled mixed. Depending on the concentration and duration, this can lead to severe poisoning to lead.

Der Erfindung liegt die Aufgabe zugrunde, erstens das Quecksilber DHim Zerbrechen des Thermometers am Austreten zu hindern und zweitens die Bruchgefahr des Glaskörpers zu mindern.The invention is based on the object, firstly, the mercury Preventing the thermometer from leaking out when the thermometer breaks and, secondly, the risk of breakage to reduce the vitreous.

Dies erfolgt durch Ummantelung des Glaskörpers mit einer geschlossenen Kunststoffhülle. Die Meßgenauigkeit wird durch aLe durchsichtige Ummantelung nicht verändert; die Meßdauer s;arn unter dmstarlden geringfügig verzögert werden. Dieser iTanriteil wird aber durch die Verhinderung des unkontrollierten Verdampfens von Quecksilber bei weitem ausgeglichen.This is done by sheathing the glass body with a closed one Plastic cover. The measuring accuracy is not affected by a transparent coating changes; the measurement period s; arn to be slightly delayed under dmstarlden. This iTanriteil is made by preventing the uncontrolled evaporation of Mercury balanced by far.

Angestrebt wird auch eine Herabsetzung der Bruchwahrscheinlichkeit dadurch, daß die Ummantelung nicht einheitlich stark sein muß, sondern an den kritischen Stellen eine oesondere Verstärkung erhält.The aim is also to reduce the probability of breakage in that the sheathing does not have to be uniformly thick, but rather on the critical ones Make a special reinforcement.
