Description

The invention relates to radiation protection clothing for shielding radiation, which is emitted by a radiation source, in particular an X-ray source, according to the preamble of claim 1.

For example, is from the US 4,843,641 a radiation protection jacket is known which has at least one Velcro strip on a lower layer and a corresponding Velcro strip on the upper layer of the radiation protection clothing, wherein the corresponding Velcro strips overlap at least partially when the radiation protection clothing is worn by a person. Furthermore, the radiation protection clothing comprises an at least partially elastic belt, which also has Velcro strips at its ends, which allow the attachment of the belt around the hips of the radiation protective clothing wearer.

Furthermore, from the German Utility Model Gm 77 07 129 an X-ray apron is known which comprises a front part and two backs and a closure for holding the backs, wherein at each back a band is attached, at its end a Velcro closure layer is, and complementary Velcro layers the apron are provided, on which the Velcro layers at the end portions of the bands after they are crosswise guided over the other back part, for the purpose of producing an adhesive bond can be placed. The complementary Velcro closure layers for the Velcro layer of each band are arranged on the other back part.

A disadvantage of the known from the above patent or utility model writings Radiation protection garments is in particular that the complementary Velcro layers, in particular the so-called wool part, lose their adhesive force by frequent opening and closing of the Velcro connection. Over time, it is therefore no longer possible to ensure a secure connection between the complementary velcro layers or a correct and secure fit of the radiation protection clothing.

This is particularly noticeable in the X-ray apron known from the Gm 77 07 129, since this is fixed only by two tapes provided with Velcro, which are secured in the back area, so that the not inconsiderable weight of the X-ray apron rests exclusively on the shoulders of the wearer and thereby the Velcro connection in the back area is exposed to strong tensile forces. This can occur when the Velcro connection becomes fatigued, so that the X-ray apron accidentally slips off the shoulders.

Although it is possible to separate the complementary Velcro layers of the radiation protection clothing and to fix new Velcro layers on the radiation protection clothing, but this is expensive and therefore costly. The particular problem with this is that the radiation protection layer, which prevents the ionizing radiation, when sewing or otherwise attaching the Velcro layers must not be penetrated by seams, rivets or the like. Therefore, in most cases, a large part of the radiation protection clothing must be separated and re-sewn, so that this effort is not worthwhile.

From the US 4,843,641 is a garment for wearing in a radioactive environment known. The known garment comprises a front and a back part, a shoulder part to hang the garment on a user, and an elastic belt, which is preferably attached to the garment at the waist or waist.

The object of the present invention is to provide a radiation protection clothing in which Velcro parts can be exchanged in a simple manner and which ensures a reliable protection against radiation.

The object is achieved by the characterizing features of claim 1 in combination with the generic features.

Advantageous developments of the invention are specified in the subclaims.

Advantageously, Velcro fasteners, which are located in the end region of fastening straps of the radiation protection clothing, for example, with zippers, snaps or snap fasteners can be fixed to the radiation protection clothing. Since these straps are usually in a range of radiation protection clothing, which is not relevant radiation absorption technology, can be fixed to the fastening straps in a simple way rivets, zippers or snap buckles and the complementary Velcro parts.

Furthermore, the complementary Velcro fastener parts can also be arranged on the surface of the radiation protection clothing, for example by means of zippers, in such a way that they are interchangeable even in areas which are relevant to radiation without impairing the safety of the radiation protection clothing.

Particularly advantageous is the attachment of the Velcro fastener parts by means of another Velcro fastener connection, wherein one of the complementary Velcro fastener parts is attached to the surface of the radiation protective clothing and on it a double-sided Velcro part is placed at these positions. Since the bottom velcro is rarely opened and closed, the adhesive force is very high, so that a secure fixation is given with easy interchangeability.

Furthermore, it is advantageous that none of the fastening measures on a fixture in radically relevant The field of radiation protection clothing is dependent. The attachment can be made in each case on fastening straps, straps or a radiation-technically not relevant outer shell or the upper layer of radiation protection clothing.

Fig. 1A and 1B show a first exemplary radiation protective clothing 1, which comprises a front part 2, which shields the body of the wearer from the shoulders to about knee height against ionizing radiation, and fastening straps 3. Radiation protection clothing of this type is used in particular for the shielding of X-rays in the surgical and diagnostic field of clinics and medical practices.

The radiation protection clothing 1 has in the present embodiment, two straps 3, which are placed over the shoulders of the wearer, crossed behind the back and by means of complementary Velcro fastener parts 4, which are fixed to the fastening straps 3 and the front part 2 in corresponding positions, are attached. The complementary Velcro parts 4 are attached to the radiation protection clothing 1, that the protective function against the radiation remains unaffected. In particular, the lead-containing layer of radiation protection clothing 1 serving for shielding is not penetrated by seams, rivets or the like.

In the in Fig. 1A illustrated embodiment of an exemplary radiation protection clothing 1 is a so-called tooth part 4b of the complementary Velcro parts 4 arranged laterally on the front part 2 of the radiation protection clothing 1 and a so-called wool part 4b of the complementary Velcro parts 4 fixed to the ends of the fastening bands 3. The complementary Velcro parts 4 are arranged so that they overlap at least partially and thereby apply a holding force which is large enough to fix the radiation protection clothing 1 securely on the carrier.

Fig. 1C shows in a schematic representation of the in the Fig. 1A and 1B shown radiation protection clothing 1 in expanded state. On the front part 2, as already mentioned above, the tooth parts 4b of the complementary Velcro parts 4 fixed. In the same way, the wool part 4a of the complementary hook and loop fastener parts 4 can be fixed to the front part 2 of the radiation protection clothing 1. The respective complementary hook and loop fastener parts 4, in the present case the wool parts 4a, are not visible at the ends of the fastening straps 3.

To improve the fit of the radiation protection clothing at least one elastic zone 5 is provided in the shoulders of the wearer, which allows a limited stretching of the fastening bands 3.

In order to remedy the aforementioned disadvantages of fatigue, in particular of the wool part 4a of the complementary Velcro parts 4, various possibilities of interchangeable Velcro parts 4 are described below. In Fig. 1C are zippers 6 are provided at various positions of the radiation protection clothing, which can be arranged for example in the end region of the fastening bands 3 or in the shoulder region of the radiation protection clothing 1. On the left the in Fig. 1C shown fastening straps 3 is shown as the simplest fastening measure a zipper 6, through which the located at the back of the fastening tape 3 wool part 4a of the complementary Velcro parts 4 is connected to the end of the fastening tape 3 releasably connected to the radiation protection clothing 1. Is the wool of the wool part 4 a by frequent opening and closing when Anund undressing the radiation protection clothing 1 so badly damaged that the secure fit of the radiation protection clothing 1 is not guaranteed, the zipper 6 is opened, which removes the wool part 4 a part of the fastening tape 3 and through replaced a new one.

Since the elastic zones 5 are claimed by frequent use and in particular by the not inconsiderable weight of the radiation protection clothing 1 and thereby lose their elasticity with time, it is under It may be desirable to exchange both the velcro velcro parts 4 and the elastic zones 5 together. A corresponding arrangement is Fig. 1C to remove the right of the two straps 3. In this case, both the elastic zone 5 and the zipper 6 can be arranged at an arbitrary position of the fastening band 3.

In Fig. 1D Another possibility of attachment of the Velcro part 4 having the end of the fastening strap 3 is shown. In this case, the attachment of at least one, preferably several snaps 7 is taken. In this case, an upper part of the push buttons 7 is fastened to one side of the fastening band 3, for example by riveting, while the counterpart of the push buttons 7 are located on the releasably connectable part of the fastening band 3 with the Velcro fastener part 4. If necessary, the snaps are simply opened and a new end of the fastening tape 3 with the corresponding snaps buttoned again.

The Fig. 1E and 1F show a further fastening means of snap fasteners 8, which in Fig. 1E in open and in Fig. 1F are shown in the closed state. In the illustrated embodiment, the connection is performed by 2 snap fasteners 8. If necessary, the snap buckles 8 are released by squeezing lateral legs of the buckles 8a in the closure parts 8b. A corresponding new end with closure parts 8b fastened thereto can be connected to the fastening strap 3 by means of simple attachment of the closure parts 8b to the buckles 8a. Particularly advantageous in this embodiment is the ability to integrate the elastic zones 5 in fastening tabs 9 of the snap buckles 8 by the fastening tabs 9 are made of elastic material.

The FIGS. 2A and 2B show a further exemplary radiation protection clothing 1 in a relation to the in Fig. 1 shown radiation protection clothing modified embodiment.

While the front part 2 of in Fig. 2A illustrated radiation protection jacket 1 in about that in Fig. 1 is equal to, is from the back view in Fig. 2B It can be seen that, due to the protective function required by the back parts 10 of the radiation protection clothing 1, the fastening straps 3, which can be made interchangeable, are shorter. In order to ensure the protective function of the back parts 10, the elastic zones 5 and the zippers 6 must be arranged relatively close to one another in the end region of the fastening straps 3. In Fig. 2B are again exemplified zippers 6 shown for releasable connection. It can, however, as in the Fig. 1C to 1F also push buttons 7 or snap buckles 8 are used for releasable connection.

The front part 2 of the radiation protection clothing 1 in turn has two hook and loop fastener parts 4, which in the present embodiment in the tooth parts 4b exist, on which the wool parts 4a are placed on the back parts 10 of the radiation protection clothing 1 for attachment. For releasable connection of the tooth parts 4b turn, for example, a circumferential zipper 6 or a double-sided Velcro part can be used. In both cases, the hook-and-loop fastener part 4 can be sewn, sewn or riveted onto a textile cover 11 enveloping the radiation protection layer without impairing the radiation protection function of the radiation protection layer.

In the FIGS. 3A and 3B is a radiation protection clothing 1 for the protection of the thyroid and the sternum, which is also referred to as Sternumschutz 12 shown. Fig. 3A shows the sternum protection 12 in the applied state, wherein a push button strip 13 is provided, for example, for fixing the Sternumschutzes 12 at another part of the radiation protection clothing 1.

As already explained in the previous exemplary embodiments, the complementary hook-and-loop fastener parts 4, in particular the wool part 4a, can in turn be connected to the sternum protector 12 by various measures. The right fastening band 3 in Fig. 3B is provided with a zipper 6, while the left mounting band 3 in Fig. 3B has a series of snaps 7. Also the fixation by means of in Fig. 1E and 1F shown snap fasteners 8 is conceivable. Also, to improve the fit elastic zones 5 may be arranged at any point of the fastening bands 3. These can be designed so that they are interchangeable with the complementary Velcro parts 4.

In the present embodiment, in particular the variant of the attachment would offer by means of a double-sided Velcro closure part, after the Sternumschutz 12 is relatively small and therefore relatively light. As a result, excessive weight loading of the Velcro connection is avoided and ensures a particularly easy replacement.

The invention is not limited to the illustrated embodiments and, for example, for any radiation protective clothing such as full-body shields for infants, dental aprons or the like applicable.
