Method for manufacture of medicinal plaster bandage

FIELD: medicine, in particular, manufacture of plaster bandages used in traumatology and orthopedics.

SUBSTANCE: method involves applying ground hemihydrate plaster to base and fixing said plaster thereon; using multilayer base; preliminarily applying ground hemihydrate plaster onto each layer of said base; applying layers onto each other and fixing plaster on base; rolling base and placing resultant base roll into plaster fixing enclosure and further into tight package, which fixes shape of article.

EFFECT: provision for producing of high-quality and high-strength article convenient in use.

 

The invention relates to medicine, namely to manufacture medical plaster bandages applied in traumatology and orthopedics.

Of all known methods of producing such bands closest to the invention is a method of rubbing gypsum or plaster powder into the surface of the gauze manually or mechanically (BAM GU, Chernavsky, VA "Plaster bandages in orthopedics and traumatology". M.: Medicine, 1966, page 135).

The disadvantage of this method is unsatisfactory as bandages (hereinafter bandages) due to the scarcity of gypsum on the surface of the gauze, formed as a result of shedding it dry gypsum storage and leaching of gypsum with water in the process of soaking the bandage.

All other ways of making plaster bandages directed, in the main, to the elimination of these two drawbacks - shedding and leaching of gypsum as the number located on the surface of the gauze soaked and prepared to overlay bandage is, ceteris paribus, the main factor in strength and, accordingly, the quality of the bandage.

To this end, apply the liquid adhesive components in the form of water and even water-alcohol solutions of cellulose ethers and the like, which, in turn, in addition to the high cost of the components requires additional costs for drying the gypsum slurry, and therefore greatly complicated and dorogaya production cycle.

Meanwhile, to eliminate asiaeast dry gypsum storage bandage is possible by prior mutual dense compression of plaster and gauze and subsequent careful preservation of immobility between all layers of bandage, wrapped into a roll and placed in a tightly fitting the roll form high strength. This form, for example, can be Packed in shrink film.

Before applying the bandage is kept mainly in the collapsed state by immersing the whole roll into the water, which reduces the time of application of the bandage and provides the convenience of staff.

Here is a preliminary location of the roll in the filter does not pass the plaster shell eliminates the leaching of gypsum in water, and the possibility of free no spin drain excess water reduces the possibility of accidental rupture of the filter shell and uncontrolled in this case, the loss of plaster.

The strength of the bandage is required for firm clamping of the parts of the bone and other tissue, is achieved in medical practice, the imposition of 8-12 layers of bandage, as normalized a thickness of only 0.8 mm

In terms of the minimum time to fixation of tissues such amount imposed layers is at least not justified and may be replaced by the imposition of all, for example, 3 to 4, W is 3-ply bandage, the thickness of which, in this case, will be only 2.4-2.5 mm, This bandage is guaranteed to have the same cosmetic properties as a single layer and will ensure a snug fit all irregularities of projections and depressions - fixed tissue surface, and the number of operations and time overlay bandage is reduced at least three times. In addition, trehalose bandage during operation the overlay provides almost complete mutual immobility between the three adjacent layers of bandage, and thus eliminates loss of gypsum at this stage.

Laboratory studies on the operations of the proposed method showed complete its applicability and the possibility of serial production on industrial equipment, high-quality, and most importantly, high-strength product.

On each of the three pieces of gauze length of 1 m and a width of 14 cm was applied manually in 90 g water-gypsum required performance of fineness of grind, the start time and end time setting. Required then each of the other segments were placed on a hard flat surface, covered with a layer of the same plaster thickness of 4-5 mm, and then hand-roller at him with a hinged load 15 kg (i.e. <1.0 kg per 1 cm rolled the width of the bandage several times already rolled three-layer bandage, after which the bandage was rewind the roll diameter ≈50 mm with the Last maximum is s ' adherence to its cylindrical and straight surfaces in the paper for the packaging of tea so so when soaking to eliminate the possibility of opening the bag (for example, wrap the thread several times). The thus prepared the roll was sealed in shrink-wrap with a maximum force of shrinkage, i.e. compression.

After a short (several days) storage film cover was removed, a bandage untouched paper membrane was immersed in water at room temperature on time reliable soaking - up to 50 with and without subsequent crimping of the excess water was navedyvalsja on the wall rod in position ≈30-45° to the horizon, where it was maintained for another 15-30 s for free drainage of excess water. After removing the paper wrapper the entire plaster except for the part on its outer layer (and the whole surface of this layer is 0.04 working surface of the bandage remains on the gauze in the form of a bandage, ready to overlay up to three layers. However, the absence of influence of any of the components on the indicators setting time and strength of the gypsum gives you the opportunity to have them with maximum precision.

A method of manufacturing a medical bandage, comprising applying on the basis of ground water of gypsum and securing it to the base, characterized in that the use of multilayer-based system, each layer of which is pre-applied ground water gypsum layers impose one on the UGA, then fasten gypsum-based, the basis is coiled, is placed in the filtration plaster shell, and then in a dense packing, fixing the form of the product.
