Abstract

The medical plaster incorporates a lead layer which absorbs gamma or X-ray radiation. This lead layer is either smooth or with greater thicknesses is folded or laminated so that the plaster can conform to the body contours of the patient. On its packaging the plaster carries an indication of the absorption value of the clinically most important isotope. The plaster has at its base a wound-covering layer with adhesive zones, above which is the lead absorbing layer. There is an intermediate layer of cellular material, and an outer plastic covering. ADVANTAGE - To protect the ambiance of a patient being treated with a radio-isotope therapy.

Description

In der modernen Therapie der Hirntumoren wird oft eine Implantation von Radionukliden durchgeführt. Dabei wird mittels einer kleinen Kanüle ein Radioisotop in das Zentrum des Tumors eingebracht und der Tumor von innen zerstrahlt. Die dabei auftretende Strahlung, insbesondere an der Stelle des Trepanationsloches von 8-15 mm Durchmesser, führt jedoch auch zu einer Strahlenbelastung der Umwelt. Daher ist es geboten, diese nach außen dringende Strahlung abzuschirmen. Durch ein Pflaster, - wie in Abb. 1 dargestellt - das ein strahlenabsorbierendes Medium enthält (Blei od. ähnliches) kann bei dem heute vorwiegend verwendeten Isotop I-125 eine praktisch vollständige Absorption erreicht werden. Damit können die Patienten wieder am normalen Leben teilnehmen, was sonst nur mit Einschränkung bzw. mit einer bestimmten Strahlenbelastung der Umwelt möglich wäre.In modern therapy of brain tumors, radionuclides are often implanted. A radioisotope is inserted into the center of the tumor using a small cannula and the tumor is blasted from the inside. However, the radiation that occurs, particularly at the location of the trepanation hole with a diameter of 8-15 mm, also leads to radiation pollution of the environment. It is therefore necessary to shield this radiation, which penetrates outwards. A plaster, as shown in Fig. 1, which contains a radiation-absorbing medium (lead or the like) can be used to achieve practically complete absorption in the isotope I-125, which is predominantly used today. This enables patients to participate in normal life again, which would otherwise only be possible with restrictions or with a certain radiation exposure to the environment.

Da das Isotop I-125 Photonen mit Gammaenergien zwischen 29 und 35 KeV emittiert, ist im einfachsten Falle das Pflaster auf diesen Energiebereich ausgelegt. Da die Halbwertsschicht für Blei bei diesen Energien rund 0.025 mm beträgt und zehn Halbwertsschichten eine Herabsetzung der Strahlung auf rund ein Promille bewirken, kann mit einer Schichtdicke von 2 mm ein fast vollständiger Schutz der Umwelt erreicht werden. Dabei ist wichtig, daß sich auf der Pflasterverpackung eine genaue Bezeichnung über die Strahlenschutzwerte befindet.Since the isotope I-125 photons with gamma energies between 29 and 35 KeV is emitted, in the simplest case the patch is on this Energy range designed. Since the half-value layer for lead at these energies is around 0.025 mm and ten half-value layers cause the radiation to be reduced to around one per thousand, can provide almost complete protection with a layer thickness of 2 mm of the environment. It is important that the A precise description of the plaster packaging Radiation protection values.

Umgekehrt kann mit dem Pflaster auch eine aus therapeutischen Gründen von außen erfolgende Bestrahlung so optimiert werden, das bestimmte Hautregionen des Patienten eine definiert geringere Dosis erhalten.Conversely, the patch can also be used for therapeutic purposes Reasons from outside radiation are optimized so that certain areas of the patient's skin have a defined lower dose receive.

Gemäß den verschiedenen Anwendungen sind eine Reihe von Ausführungen möglich. In Abb. 1 ist eine der denkbaren Ausführungen dargestellt: 1 - Klebezone, 2 - Pflasterabdeckung, 3 - absorbierende Schicht, entweder mehrlagig oder - bei höherer Schichtdicke, gegliedert wie dargestellt in Abb. 2. In letzterem Falle besteht die Absorberschicht - wegen der notwendigen Anpassung an die Körperkonturen des Patienten - aus einzelnen Lamellen, die überlappend angeordnet sind, wie Abb. 2 im seitlichen Schnitt zeigt. 4 - Zwischenschicht aus Plastik- oder Zellstoff-Folie, 5 - wundversorgende Pflasterschicht. Es ist auch ein Ausführung denkbar, bei der das Pflaster in Form einer Tasche ausgeführt ist, so daß ein oder mehrere Absorptionsfolien eingelegt werden können.A number of designs are possible according to the different applications. In Fig. 1 one of the conceivable versions is shown: 1 - adhesive zone, 2 - plaster cover, 3 - absorbent layer, either multi-layer or - with a higher layer thickness, structured as shown in Fig. 2. In the latter case, the absorber layer exists - because of the necessary Adaptation to the body contours of the patient - from individual lamellae, which are arranged overlapping, as Fig. 2 shows in the lateral section. 4 - intermediate layer made of plastic or cellulose film, 5 - wound-dressing plaster layer. An embodiment is also conceivable in which the plaster is designed in the form of a pocket, so that one or more absorption foils can be inserted.
