ANALYSIS OF PHYSICAL AND CHEMICAL PROPERTIES OF INDIVIDUAL DRESSING PACKS

Individual dressing pack (IDP) constitute one of the main components in the military first-aid kit of military personnels, being the most important element of the material equipment for assisting the wounded and sick soldiers. Constantly developing new IDP types should fully ensure the provision of medical care at the stages of medical evacuation in accordance with the latest achievements of science and practice. This article discusses to the analysis of IDPs with an expiring shelf life on the subject of packaging integrity and determination of physical-chemical properties such as tightness of the seam, moisture and capillarity of the material. The external inspection of the packages allowed making a conclusion that the packaging material did not lose its functionality after storage during 5 years. To analyze the physicochemical properties, it was used five dressing bags according to GOST 1179-93, an apparatus for determining capillarity and wettability, and a gravimetric method. The tightness of the seam was determined according to GOST 1172-93, capillarity - according to GOST 3816-81, the humidity of the bandage - according to GOST 3816-81. Descriptive statistics of the experimental results was performed. A comparative analysis of the obtained data compared with GOST standards allowed us to conclude that it is advisable to use IDP on the ending shelf life and for a period after the expiration date indicated on the package.
