Abstract

A plaster of paris bandage is disclosed comprising a bandage impregnated with a powder comprising plaster of paris mixed, prior to impregnation of the bandage, with an additive which forms a viscous solution when wet. Adhesion of the plaster of paris to the bandage is thereby improved when the bandage is wet. Prior to wetting cohesion of the dry powder is improved by moistening the powder with an anhydrous liquid such as alcohol. This may be done prior to packaging the bandage for storage and sale.

Description

PLASTER OF PARIS BANDA GE CONTAINING AN ADDITIVE
Field of the Invention
This invention relates to a bandage and in particular what is commonly called a plaster of paris bandage being a bandage which is impregnated with a cementitious powder, usually calcium sulphate or gypsum, which sets hard after being wet with water. Bandages of this kind are wrapped around broken and fractured limbs to immobilise them after they have been set. Such bandages will be referred to herein as "plaster of paris" bandages and the cementitious powders with which they are impregnated will be referred to as "plaster of paris" .
Description of the Prior Art
Commonly available plaster of paris bandages comprise bleached cotton fabric impregnated with a powder made up of at least 85% by weight of calcium sulpha.te. The fabric may be treated prior to the application of the dry plaster of paris to promote the adhesion thereof to the bandage. Calcium sulphate is strongly hygroscopic so the bandage is generally packaged in air-tight packaging to prevent the powder from absorbing moisture from the atmosphere. A major problem encountered in the use of conventional plaster of paris bandages is that the wetting of the bandages creates a slurry (i.e. a mixture of water and plaster of paris) which before it sets is apt to drip off or be detached from the bandages while they are being applied. This makes a mess and the difficulty of cleaning up the mess is exacerbated since after the hardened hydrated powder has been removed a film is usually left which remains unseen until all the moisture has evaporated, necessitating a second clean up.
Another problem with conventional such bandages is that the dry plaster of paris also is apt to fall off the bandages during handling (particularly when extracting it from its package) before it is wet. This also requires cleaning up although this task is not as laborious as cleaning up the messed slurry. Summary of the Invention
According to the invention there is provided a plaster of paris bandage comprising a fabric impregnated with a powder comprising plaster of paris, characterised in that the powder is premixed with an additive which is compatible with the plaster of paris and which, when mixed with water, forms a viscous solution.
Further according to the invention there is provided a method of making a bandage including the steps of impregnating the bandage with a powder comprising plaster of paris, characterised that prior to impregnating the bandage the powder is mixed with an additive which is compatible therewith and which, when mixed with water, forms a viscous solution.
The viscous solution has the effect of rendering the slurry more cohesive and thus reducing if not entirely preventing the messing of the slurry previously referred to during application of the bandage. The additive must thus be chosen so that it has this effect. Most if not all additives which form colloidal solutions in water will probably have this effect and would thus be fall within the scope of the invention provided they were suitable in other respects. Additives other than those which form colloidal solutions might also be suitable.
The additive, which is preferably a powder, and the plaster of paris must be in suitable proportions. The proportions can vary widely and can be determined by experimentation in each case. Naturally, sufficient additive must be used to be practically effective in rendering the slurry in a practical sense cohesive; and at the same time not so much additive must be used as to interfere (again in a practical sense) with the properties of the plaster of paris. A minimum of about 0.1% and a maximum of about 5% by weight of the additive in dried powder form may be mixed with most available plaster of paris mixtures for making plaster of paris bandages. It is of considerable advantage if the additive is chosen so that it can be added to the plaster of paris mixtures made according to established methods and using existing apparatus for manufacturing the bandages without requiring any substantial changes to such methods or apparatus or to the fabrics of which available such bandages are made. For thus purpose the additive must also be compatible with the other constituents such as the setting retardants or accelerants used in available plaster of paris mixtures. The additive should, for the same reason, be able to stand up to the same processes which are in use for sterilising available plaster of paris and the bandages made therewith, including irradiation and heat processes. It is also of course necessary that the additive should have little or no toxicity. There are a wide range of additives having these properties. Among the additives which may be used and which which have the additional advantageous properties of being odourless, soluble in water over a wide temperature range and in particularly in cold water and are stable over a wide PH range are ethylcellulose, ethylhydroxyethylcellulose, ethylmethylcellulose, hydroxypropylmethylcellulose, hydroxyethylcellulose, hydroxyethylmethylcellulose, sodium carboxymethylcellulose, methylcellulose and carboxypoly methylene as well as various gums.
Further according to the invention the propensity of the dry plaster of paris to fall off a plaster of paris bandage prior to wetting it with water can be reduced by moistening the bandage after application of the dry powder with a suitable anhydrous liquid.
The liquid is advantageously sprayed on the outer surface of the rolled up bandage prior to packaging. The liquid is advantageously sprayed as a fine mist.
In one form of the invention the liquid is an alcohol such as propyiene glycol which is soluble in water and can thus disperse in the water which wets the bandage prior to application. Brief Description of the Drawing
An example of the invention is described with reference to the accompanying drawing in which
Figure 1 is a schematic perspective view of a short length of plaster of paris bandage; and
Figure 2 is a view of the bandage rolled up prior to insertion in a package.
Detailed Description of the Embodiment shown in the Drawing
In the drawings there is shown a bandage 10 comprising a conventional fabric used for making such bandages impregnated by the use of known machinery in conventional fashion with a plaster of paris powder indicated by the stippling in the drawing. The powder comprises plaster of paris (calcium sulphate) premixed with an additive which is compatible with the plaster of paris and which, when mixed with water, forms a viscous solution.
After impregnation the bandage 10 is rolled up into a roll 12 and the outer surface thereof is sprayed with an anhydrous liquid which is passed through an atomising nozzle indicated at 12 so that it emerges as a fine mist. If a single nozzle is used the roll 12 may be mounted on a spindle 14 so that it rotates about its longitudinal axis as it is being sprayed, thereby ensuring that the spray covers the outer surface of the bandage evenly.
The rolled up bandage is packaged in a conventional moisture tight package immediately after spraying. In one example of the invention, the additive is hydroxypropylmethylcellulose which is commonly called hypromellose and is readily available at an economic price in most countries in various viscosity ranges. It is also made to B.P., U.S.P and other standards. Common trade tames for this substance are Celacol HPM, Methocel HG and Methofas. It is a white or creamy white, odourless, tasteless, fibrous powder. It is a mixed ether of cellulose containing 27 to 30% of methoxyl (- OCH3) groups and 4 to 7.5% hydroxypropyl (-OC3H6OH) groups, calculated on the dried material. Solutions have a PH between 6 and 8.
In one example a quantity of 1% by weight of the above additive was added to plaster of paris, both in dry powder form. The resulting mixture was used to make a plaster of bandage as described above. The fabric used was a commercially available bandage made by Johnson & Johnson (TM). After being rolled up as described above and prior to packaging the bandage was sprayed with a fine mist of anhydrous propylene glycol so that the outer surface of the rolled up bandage was slightly moist to the touch. Acceptable results are obtained by using as little as 0.1% and up to 5% by weight of the same additive in the plaster of paris powder.
When the bandage was removed from its package much less powder became detached from therefrom. In the course of applying the bandage considerably less mess was made after the bandage was wet. It was firmer to the feel and more susceptible of control during application. The final look of the cast was better and the feel of the cast was improved.
It is not intended that the scope of the invention should exclude modifications and/or improvements to the embodiments described and/or illustrated which are within the spirit of the invention as defined in the claims or be limited by details of such embodiments further than is necessary to distinguish the invention from the prior art.
