Description

Technisches GebietTechnical field

Die Erfindung betrifft einen einteiligen Personenschutzanzug zum Schutz gegen chemische, bakteriologische und/oder radioaktive Medien, der über eine Verbindungsleitung mit einer Luftversorgungseinheit verbindbar ist.The invention relates to a one-piece personal protective suit for Protection against chemical, bacteriological and / or radioactive media, the can be connected to an air supply unit via a connecting line.

Derartige einteilig ausgebildete Schutzanzüge sind an sich bekannt. Sie bestehen aus einem overallähnlichen Anzug aus einem flexiblen Material und umfassen ein die Atemmaske bildendes kapuzenförmiges Kopfteil, das vorderseitig durch ein visierartiges Fenster verschlossen ist.Such one-piece protective suits are known per se. They consist of an overalls-like suit made of a flexible material and comprise a hood-shaped head part forming the breathing mask, the is closed on the front by a visor-like window.

Bei bekannten einteiligen Schutzanzügen erfolgt die Luftversorgung der zu schützenden Person entweder mit Hilfe von in Flaschen gefüllter Luft oder mit Hilfe tragbarer Gebläse, deren Saugseite mit einem Filteranschluß und deren Druckseite über eine Verbindungsleitung mit dem Inneren des Schutzanzuges verbunden ist. Dabei wird der Luftstrom über einen entsprechenden, an der Rückseite des Schutzanzuges angeordneten Anschluß in den Schutzanzug eingeblasen und gelangt in das kapuzenförmige Kopfteil. Die eingeblasene Luft erzeugt im gesamten Schutzanzug einen Überdruck, der auch bei eventuellen Undichtheiten des Anzuges ein Eindringen von Giftstoffen verhindert. In the case of known one-piece protective suits, the air is supplied the person to be protected either with the help of air filled with bottles or with the help of portable blowers, the suction side with a filter connection and its pressure side via a connecting line to the inside of the Protective suit is connected. The air flow is over a corresponding, arranged on the back of the protective suit Connection blown into the protective suit and gets into the hood-shaped headboard. The air blown creates throughout Protective suit an overpressure, which is also in case of possible leaks of the Suit prevents the penetration of toxins.

Damit der zu schützenden Person definiert Luft zum Atmen zugeführt werden kann, wird das gesamte Kopfteil mittels versteifender Elemente helmartig ausgebildet oder der Überdruck in dem Schutzanzug wird derart gewählt, daß der Luftstrom das Kopfteil in einen entfalteten Zustand aufbläst.So that the person to be protected is supplied with air to breathe , the entire headboard is made using stiffening elements formed like a helmet or the overpressure in the protective suit is such chosen that the air flow the headboard in an unfolded state inflates.

Nachteilig ist bei den bekannten Personenschutzanzügen vor allem, daß relativ große Luftmengen in den jeweiligen Schutzanzug eingeblasen werden müssen, was -je nach Luftversorgungseinheit- entweder einen häufigeren, sehr aufwendigen Wechsel der Sauerstoff- bzw. Luftflaschen oder die Verwendung relativ schwerer und kostenaufwendiger Gebläse erforderlich macht.A disadvantage of the known personal protective suits is above all that relatively large amounts of air are blown into the respective protective suit must become, depending on the air supply unit, either one frequent, very complex replacement of the oxygen or air bottles or the use of relatively heavy and expensive blowers makes necessary.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, einen Personenschutzanzug anzugeben, bei dessen bestimmungsgemäßen Verwendung geringere Luftmengen in den Anzug eingeblasen werden können, als dieses bei vergleichbaren bekannten Schutzanzügen erforderlich ist.The invention has for its object a Specify a personal protective suit when used as intended Use smaller amounts of air to be blown into the suit can, as this is required in comparable known protective suits is.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Anspruchs 1 gelöst. Weitere, besonders vorteilhafte Ausgestaltungen der Erfindung offenbaren die Unteransprüche.This object is achieved by the features of Claim 1 solved. Further, particularly advantageous embodiments of the Invention disclose the subclaims.

Die Erfindung beruht im wesentlichen auf dem Gedanken, das kapuzenförmige Kopfteil mindestens in Teilbereichen doppelwandig auszubilden und den dadurch entstehenden Zwischenraum als Luftkanal zu verwenden, welcher die zum Atmen benötigte Frischluft gezielt dem Gesichtsbereich der zu schützenden Person zuführt. Der Luftkanal ist hierzu über eine Verbindungsleitung mit der Luftversorgungseinheit verbunden und weist im Gesichtsbereich der zu schützenden Person Luftaustrittsöffnungen auf, über welche die Frischluft vorzugsweise oberhalb oder seitlich von dem Gesicht austritt.The invention is essentially based on the idea that hood-shaped headboard double-walled at least in some areas train and the resulting space as an air duct use, which the fresh air needed for breathing Facial area of the person to be protected. The air duct is for this connected to the air supply unit via a connecting line and has air outlet openings in the facial area of the person to be protected on which the fresh air is preferably above or to the side of the Face emerges.

Da durch die relativ kleinen Luftaustrittsöffnungen die Luft innerhalb des Luftkanals gestaut wird, ergibt sich in dem Luftkanal ein Überdruck, der zu einem Aufblasen des aus Innen- und Außenkapuze bestehenden kapuzenförmigen Kopfteiles führt. Das aufgeblasene kapuzenförmige Kopfteil bildet daher in Verbindung mit dem visierartigen, z.B. aus einer Kunststoffplatte bestehenden Fenster ein sich selbsttragendes Kopfteil, innerhalb dessen der Kopf der zu schützenden Person vorzugsweise frei beweglich ist.Because of the relatively small air outlet openings, the air inside of the air duct is stuck, there is an overpressure in the air duct which to inflate the inner and outer hood hood-shaped headboard leads. The inflated hood-shaped Head part therefore forms in connection with the visor-like, e.g. from one Plastic panel existing window a self-supporting headboard, within which the head of the person to be protected is preferably free is mobile.

Als vorteilhaft hat es sich erwiesen, wenn die Innen- und die Außenkapuze derart miteinander verbunden sind, daß sich mindestens drei im wesentlichen parallel zueinander angeordnete Luftkanäle ergeben, die von der Rückseite des Kopfteiles oberhalb der Schädeldecke der zu schützenden Person verlaufen und an den Luftaustrittsöffnungen enden.It has proven to be advantageous if the interior and the Outer hood are connected to each other in such a way that there are at least three result in air ducts arranged essentially parallel to one another, which from the back of the headboard above the cranium to the protect person and end at the air outlet openings.

Der erfindungsgemäße Personenschutzanzug hat sich insbesondere bei einmal verwendbaren Schutzanzügen bewährt, weil das Haubensystem sehr kostengünstig herstellbar ist und somit der Preis des erfindungsgemäßen Personenschutzanzuges gegenüber bekannten Einweganzügen gering gehalten werden kann.The personal protective suit according to the invention has in particular Proven for single-use protective suits because of the hood system is very inexpensive to manufacture and thus the price of Personal protection suit according to the invention compared to known One-way suits can be kept low.

Sofern es sich um einen nur einmal verwendbaren Schutzanzug handelt, sollte an dem kapuzenförmigen Kopfteil ein mechanischer Anschluß zur lösbaren Verbindung des Kopfteiles mit der Verbindungsleitung der Luftversorgungseinheit vorgesehen sein, um die Luftversorgungseinheit mehrmals verwenden zu können.If it is a one-time protective suit acts, should a mechanical connection to the hood-shaped head part for releasable connection of the head part to the connecting line of the Air supply unit can be provided to the air supply unit to be able to use several times.

In Fig.1 ist mit 100 ein erfindungsgemäßer Personenschutzanzug bezeichnet, in dem sich eine zu schützende Person 2 (Fig.2) befindet. Der Schutzanzug 100 umfaßt ein kapuzenförmiges Kopfteil 1, welches über eine Schlauchleitung 11 mit einer über dem Schutzanzug getragenen Gebläseeinheit 102 verbunden ist. Die Gebläseeinheit 102 saugt über ein Filter 103 Luft aus dem Umgebungsraum an.1 shows a personal protective suit according to the invention at 100 referred to, in which there is a person to be protected 2 (Fig.2). The Protective suit 100 comprises a hood-shaped head part 1, which has a Hose line 11 with one worn over the protective suit Blower unit 102 is connected. The blower unit 102 sucks in Filter 103 air from the surrounding area.

Das kapuzenförmige Kopfteil 1 ist vorderseitig durch ein visierartiges Fenster 3, z.B. aus einem beschlaghemmenden widerstandsfähigen Kunststoff, verschlossen.The hood-shaped head part 1 has a visor-like front Window 3, e.g. from an anti-fog resistant Plastic, closed.

Das kapuzenförmige Kopfteil 1 ist doppelwandig ausgebildet (Fig.2), derart, daß eine Innenkapuze 4 und eine Außenkapuze 5 gebildet wird, zwischen denen sich Luftkanäle 6-8 erstrecken (Fig.4), die randseitig miteinander verklebt und abschnittsweise über Nähte 9 miteinander verbunden sind. Dadurch werden bei dem dargestellten Ausführungsbeispiel insgesamt drei Luftkanäle 6-8 gebildet. Diese erstrecken sich von einem auf der Rückseite 101 des Kopfteiles 1 halsseitig angeordneten Anschlußstutzen 10, der mit der Schlauchleitung 11 zur Zuführung der Frischluft verbunden ist, über den Kopf 12 der zu schützenden Person 2 bis zu den Luftaustrittsöffnungen 13, welche oberhalb und seitlich des Gesichtsbereiches 14 der Person 2 angeordnet sind (Fig.3). Der Verlauf der Luftströmung innerhalb des Kopfteiles 1 ist in den Fig.2-4 und 6 mit Pfeilen 15 angedeutet.The hood-shaped head part 1 is double-walled (FIG. 2), such that an inner hood 4 and an outer hood 5 are formed, between which air channels 6-8 extend (Fig.4), the edge glued together and in sections with seams 9 together are connected. As a result, in the illustrated embodiment a total of three air channels 6-8 formed. These extend from one the rear 101 of the head part 1 connecting piece arranged on the neck side 10, which is connected to the hose line 11 for the supply of fresh air is over the head 12 of the person to be protected 2 to the Air outlet openings 13, which above and to the side of the Facial area 14 of the person 2 are arranged (Fig.3). The course of the Air flow within the head part 1 is in Figures 2-4 and 6 with arrows 15 indicated.

Die Luftkanäle 6-8 sind derart ausgebildet, daß die Innenkapuze 4 keine Kompression auf die Außenkapuze 5 ausübt.The air channels 6-8 are designed such that the inner hood 4th exerts no compression on the outer hood 5.

Nackenseitig sind oberhalb eines Innenkragens 19 Luftauslaßventile 16 vorgesehen (Fig.6).On the neck side, there are 19 air outlet valves above an inner collar 16 provided (Fig. 6).

Der erfindungsgemäße Schutzanzug 100, der z.B. bei Einweganzügen aus dem im Handel erhältlichen Material Tyvec C oder F der Firma DuPont bestehen kann, weist eine einzige Öffnung 17 auf (Fig.5), über welche die zu schützende Person 2 in den Schutzanzug 100 steigt oder diesen von sich abstreift. Bei der Öffnung 17 handelt es sich um eine unterhalb des kapuzenförmigen Kopfteiles 1 angeordnete, in Schulterhöhe quer von einer zur anderen Seite verlaufende Öffnung, die mittels eines Reißverschlusses 18 verschließbar ist und anschließend versiegelt werden kann.The protective suit 100 according to the invention, which e.g. at Disposable suits made of the commercially available material Tyvec C or F der The DuPont company can have a single opening 17 (FIG. 5) which the person 2 to be protected climbs into the protective suit 100 or strips this off itself. The opening 17 is a arranged below the hood-shaped head part 1, at shoulder height opening from one side to the other, which is opened by means of a Zipper 18 is closable and then sealed can.

Die zu schützende Person 2 steigt zum Anlegen des Schutzanzuges 100 zunächst in den Schutzanzug 100 wie in einen Sack ein und streift sich diesen von unten über die Beine und den Rumpf bis zu den Schultern über. Nach Anschluß der Schlauchleitung 11 der nicht dargestellten Gebläseeinheit an den Anschlußstutzen 10 wird die Gebläseeinheit 102 eingeschaltet und das Kopfteil 1 angelegt. Der Reißverschluß 18 wird dann komplett geschlossen und versiegelt.The person 2 to be protected rises to put on the protective suit 100 first in the protective suit 100 as in a sack and strips this from below over the legs and the trunk up to the shoulders. After connecting the hose 11 of the not shown The blower unit 102 on the connecting piece 10 becomes the blower unit 102 turned on and the headboard 1 created. The zipper 18 will then completely closed and sealed.

Durch die oberhalb und seitlich des Gesichtsbereiches 14 angeordneten Luftaustrittsöffnungen 13 ist eine Frischluftversorgung im Gesichtsbereich 14 garantiert.Through the above and to the side of the face area 14 Air outlet openings 13 is a fresh air supply in the Face area 14 guaranteed.

Trotz des im Halsbereich angeordneten Innenkragens 19 mit dehnbaren Bündchen, vorzugsweise aus dem Anzugsmaterial, ergibt sich durch die aus den Luftaustrittsöffnungen 13 ausströmende Luft im gesamten Schutzanzug 100 ein leichter Überdruck. Dieser Überdruck dient der Vermeidung des bewegungsabhängigen intrinsischen Unterdruckes, der unter Umständen zu einer unzulässigen Insufflation von kontaminierter Außenluft führen würde.Despite the inner collar 19 arranged in the neck area stretchable cuffs, preferably from the suit material, results through the air flowing out of the air outlet openings 13 as a whole Protective suit 100 a slight overpressure. This overpressure serves the Avoidance of motion-dependent intrinsic negative pressure, the under certain circumstances to an inadmissible insufflation of contaminated Outside air would lead.

Die Erfindung ist selbstverständlich nicht auf das vorstehend beschriebene Ausführungsbeispiel beschränkt. So ist es beispielsweise auch möglich, die Luftauslaßventile in den Bereich unterhalb des Fensters 3 des kapuzenförmigen Kopfteiles zu legen.The invention is of course not based on the above described embodiment limited. So it is, for example possible the air outlet valves in the area below the window 3 of the hood-shaped headboard.

Ferner kann, wie aus Fig.7 ersichtlich ist, die Schlauchleitung 11 auch innerhalb des Schutzanzuges 100 liegen und die Gebläseeinheit 102 unter dem Anzug getragen werden. In diesem Fall wird das Filter 103 durch eine Öffnung des Schutzanzuges an die Gebläseeinheit 102 angeschraubt. 7, the hose 11 can also lie within the protective suit 100 and the blower unit 102 underneath to be worn with the suit. In this case, the filter 103 is replaced by a The opening of the protective suit is screwed onto the blower unit 102.
