Envelopes Surgical Grade
The packages for surgical sutures are used according to the nature of the suture and its intended use. In general the ideal packaging maintains and protects the suture during handling and storage, also allows the suture ready to be removed from its packaging with a minimum of handling and difficulty.
REQUIREMENTS OF PACKING MATERIAL
- - Permeable to sterilizing agent
- - Resistant to microorganisms entrance
- - Resistant to breakage
- - Do not leave fibers or particles
- - Do not react with the sterilizing agent
- - Do not react with the packing material
- - Resistant to liquids
- - Non-toxic (inks, fibers, fluff)
- - Cost / benefit positive ratio
For dry absorbable sutures (Braided Black Silk, Nylon Monofilament, etc) Surgical Grade Paper Envelopes are used.
For Synthetic absorbable sutures (Polyglycolic acid, polyglactin, polydioxanone, polyglecaprone) aluminum envelopes are used.
For Absorbable Sutures (Chromic Catgut, Catgut Simple) F4 Film envelopes are used
ENVELOPES OF PAPER SURGICAL GRADE
This is the ideal material for the sterilization process. In its development no optical bleaching are added. The weight is 60 to 65 g/m2, neutral pH and has high tear resistance.
It consists of a binding glue and cellulose fiber for extra long fibers having high strength, this leads to high mechanical stability. Cellulose fibers are linked into a sheet using a glue, in this case a moisture resistant glue, this is needed to make the paper resistant to sterilization and during storage to protect the product against humidity, otherwise should lead to contamination.
ENVELOPES OF ALUMINUM
This type of container is highly resistant to penetration by water vapor and gives high protection to sutures moisture sensitive; therefore, synthetic absorbable sutures are well protected against degradation by atmospheric moisture diffused into the container through the heat seal during storage.
Synthetic absorbable sutures as homo-polymers and co-polymers of lactic and glycolic acids are known to be susceptible to degradation by hydrolysis, even by small amounts of water vapor. Care must be taken on using the container to substantially remove all suture moisture traces from inside the container to seal the suture in a substantially anhydrous environment.
Aluminum envelopes provide a perfect barrier against suture biological contamination and have adequate protection against water vapor entrance. When a conventional container is stored for long periods of time under conditions of temperature and humidity, a large amount of water vapor can penetrate into the container through the heat seal layer to attack and degrade the suture material.
Resistance to water vapor permeability of packaging sutures and sealed laminated heat is significantly better by providing an airtight container to the atmosphere, featured by an important lack of bubbles in the seal area.
SOBRES DE FILM F4
They are made of Tereflatate Polyethylene material heat-sealed on three sides, transparent, without impressions, especially to contain the liquid preservative used for Catgut Chromic and Simple strands conservation.
