Abstract
Disclosed is a method for producing a mud suspension for a two-dimensional bandage tissue, comprising the following steps: - the mud is spread on a flat surface and air-dried; - the dried mud is broken into pieces; - the pieces of mud are ground to mud powder by means of a grinding device; - water, preferably purified sea water, is added to the mud powder at a given ratio and stirred so as to obtain a suspension; and - the suspension is applied to the two-dimensional bandage tissue.
Description
METHOD FOR THE PRODUCTION OF A
MUD SUSPENSION FOR BANDAGE TISSUE
This invention relates to a method for preparing a mud suspension for a planar dressing woven fabric and a dressing woven fabric with a mud suspension.
Fango compresses have been known for thermal therapy for a long time. To this end, a finely ground, sulphurous fango is strewed into cotton pad webs and is enveloped with gauze. The fango compresses are heated in hot water of 50° to 60°, are squeezed out and are applied for 20 to 60 minutes depending on the doctor's instruction while being held in place by a cloth or bandage.
The French Laid-Open Patent Application No. 80 02 506 has made known cataplasms which contain a marine mud based product. The marine mud is dehydrated and is pulverized subsequently. Similarly to the case of the fango pack, water is added to the cataplasm prior to use.
DE 39 39 926 has made known a planar dressing woven fabric which is coated with a suspension. The suspension employed is a peloid suspension of marine mud, natural moor or fango. The dressing woven fabric thus obtained has elastic properties and serves as a compression dressing. Active substances pass over from the wet peloid suspension into the body part to be treated and are resorbed there.
The mud has been left in its natural condition hitherto whenever the peloid suspension is prepared. Subsequently, a penetrating hydrogen sulphide odour was felt to exit from the compression dressing thus prepared. It particularly occurred when a pack including the peloid was opened on the dressing woven fabric. The dressing applied in a wet condition will also give off a penetrating hydrogen sulphide odour and exhibit annoying brown to black stains in the course of its desiccation.
../2 It is the object of the invention to provide a mud suspension for a dressing woven fabric in which no odour will develop and which will present a uniform colour when in a dried condition.
According to the invention, the object is achieved by a method having the features of claim 1. Advantageous aspects of the inventive method form the subject of the pertinent sub-claims.
In the inventive method, mud is spread over a flat substrate and is dried in the air with great care. Preferably, it is dried at an ambient temperature to ensure that the components are dried particularly gently. The dried mud is broken into pieces subsequently which are ground in a mill to form a powdered mud. The powdered mud is stirred while water, preferably purified sea water, is added thereto at a predetermined ratio to form a suspension, and the suspension is applied to the planar dressing woven fabric. The advantage of this method consists in that a nasal nuisance by the odour of the hydrogen sulphide will not occur while the mud dressing is being dried. Rather, it was found out that the mud suspension thus obtained will get dry uniformly without any occurrence of an odour or stains.
In addition, the advantage of the inventive method is that it avoids forming lumps in the mud suspension. The known method employs the mud as left in its natural state which often includes small lumps or solid fractions. Even if the mud is stirred at a high speed those components thereof will not disintegrate completely so that annyoing irregularities can also occur in the dressing later and can even result in pressure sores. In addition, an advantage of the inventive method is that the moisture content and water content can be determined very accurately and repeatedly after the drying step.
In an advantageous aspect, the planar dressing woven fabric is formed as a compression dressing, preferably in the form of a bandage. The compression dressing has the advantage that it acts as an active-substance dressing when applied in a wet condition. More specifically, such a dressing including a mud suspension ./3 has a decongesting effect immediately after it is applied. Likewise, it was found out that concomitant inflammatory affections will occur more rarely. When in an excessively refrigerated condition, the mud additionally alleviates pains and causes hyperaemia.
The inventive mud suspension will have dried up after abt. 2 to 3 hours to an extent that it becomes as hard as plaster of Paris. In other words, the active-substance dressing originally applied turns into a support dressing. The advantage which the support dressing has over known plaster dressings or zinc gelatinous dressings is that hypersensitive reactions, e.g. pruritus, have not become know up to now. Hence, unlike the known support dressings, the mud suspension prepared according to the inventive method will be capable of providing a hypoallergenic support dressing.
In preparing the powdered mud, the mud is spread on the substrate at a thickness of about 0.5 cm to 4 cm, preferably at a thickness of about 2 em.
The time it needs to dry in the air is about half a day to four days. When the mud thickness is 2 cm it is preferably sufficient for the mud to dry for 2 to 3 days.
The ingredients can be added to the mud or powdered mud prior to or after the drying procedure, depending on their types. The water fraction is about 30 to 50 by weight during the preparation of the suspension. The water added generally is purified sea water.
The inventive object is also achieved by a dressing woven fabric with a mud suspension which is produced according to the inventive preparation method where the dressing woven fabric preferably has the shape of a bandage, particularly a bandage for a compression dressing.
