Preparation of gypseous bandage, londet, applyings and puttings off

The most spread shape of bandages which harden, is available a plaster bandage which allows to fix well spalls of bones at fractures as a result of a prompt indurations. Gypsum СаSО4 x 2H2O - the mineral spread in the nature. For plaster bandages use the inciderated gypsum (at an incideration he loses a part of crystal water). After wetting he enters with water a chemical combination and within several minutes is transmuted into firm mass. The medical gypsum should look like a white powder, without blobs, soft at a palpation. If in him its blobs come across is necessary sits through a bolter. To maintain gypsum it is necessary in a dry place as he easily retracts a moisture. If the gypsum has dampened, it is necessary to dry - to pour out it on an iron leaf not thick and to deliver in the heated case for some minutes at temperature +120°С.

The indication to application of plaster bandages

 The Immobilization of fractures.

 The Immobilization of patholologically variated bones and joints.

 Correction of strains.

 Prophylaxis of strains.

 Urgent gypsuming.

 Manufacturing shapes and mould pieces of separate parts of a body with the purpose of a prosthetic repair.

 The Immobilization, as a method of treatment of combustions and arrangements of the soft tissues at absence of fractures.

Before applying of a plaster bandage it is necessary to check quality of a gypsum.

Assays on quality of gypsum

 The Gypsum and water in the ratio 1:1 admix and make a globule; in 7-10 minutes he should harden and not be broken at slope from height 1м.

 It is plotted gypsies mixture from an admixture of a gypsum with water of a consistence of fluid sour cream which smear a lamina on saucer, thus the good-quality gypsum hardens in 5-6 minutes; at pressing by a dactyl the gypsum should not crush and on its surface the moisture should not act.

 Impose on a brush or a forearm made of 2-3 stratums gypsum and the bandage moistened by water longet: the good-quality gypsum hardens in 5-7 minutes, and at putting off from an arm such splint is not crumbled, maintaining the shape given to her.

 The Gypsum fill in metal ware and preheat on an electrical tile. Above a gypsum hold a pocket mirror. If the pocket mirror has misted over - from a gypsum steam is oozed. Such gypsum for use is unsuitable, for contains a moisture.

 The Small part of gypsum to admix with water and to define an odor of gypsum. If the gypsum has an odors of rotten eggs - he oozes a hydrogen sulfide and not applicable to use.

 At a tightening of a gypsies powder in a fist he should transit freely between dactyls and at a unclamping of a fist on a palm there should be an inappreciable quantity of a gypsum. At such assay he is considered applicable for use.

At wetting by hot water the gypsum hardens more promptly, cold - more slowly. Normally for wetting gypseous bandage use water of temperature +30-35°С.
