Definitions
- the present invention privilege refers to an innovative thermoplastic material for veterinary use as an orthopedic immobilizer, which consists of the combination of specially treated textile materials with a low melting, thermally-adhesive, easily molded polymeric structure providing stabilization of the areas immobilized after cooling.
- the veterinary literature cites two methods, closed or conservative (crutches, molds, plasters, bandages, etc.) and open or surgical (orthopedic plates and screws, cerclage wires, intramedullary pins and percutaneous pins) (Newton and Nunamer 1985, Fossum et al., 1997, PIERMATTEI, FLO, 1999).
- fixation technique depends on the age and size of the patient, the axial stability of the fracture, concomitant musculoskeletal lesions, associated soft tissue conditions, patient cooperation, facilities and materials available and the capacity of the veterinarian surgeon .
- Orthopedic cotton bandages (elastic or not), plaster bandage (gypsum), flat metal plates (such as aluminum, iron etc.) and / or common plastics are currently known and used by veterinary surgeons.
- plastics such as Polypropylene, Polyethylene, Polyvinyl Chloride, etc. coated with bandages and adhesive tapes, in addition to preformed common plastic orthoses.
- the object of the present invention privilege relates to an innovative thermoplastic material for veterinary use as an orthopedic immobilizer in order to make a bracing directly with the anatomy of an animal patient. This is achieved by combining specially treated textile materials with a low melting, thermally-adhesive, easily molded polymeric structure which provides easy, rapid and functional stabilization of immobilized areas after cooling.
- thermoplastic material of the invention has in its composition woven and / or nonwoven base textile material specially treated with a waterproofing and antimicrobial additive and auxiliary in the dermatological protection, thus reducing dermatitis, allergies and itching; these treatments in their textile portions allow the product to have a differentiated performance in its application process and the ability to minimize damage and injury to immobilized limbs.
- the material of the invention has a combination of special polymers which, due to its low temperature thermal reactivation characteristics (between 60 ° C to 90 ° C), low recrystallization rate, that is, after being heated to its softening temperature, the polymer (s) remain malleable and tacky for a long period of time (generally greater than 60 seconds) and after cooling the material to room temperature, it returns to the original rigidity and hardness.
- thermoplastic material for veterinary use as an orthopedic immobilizer, exclusive and unique in relation to the other products available in the market, and its constructive characteristics offer as advantages:
- the polymeric and textile composition of the material object of the invention confers a residual open time of its malleability and bonding in such a way as to enable the handling, application and post adjustment and positioning of the strips, sheets, blades, etc. in the members to be immobilized animal patients.
- This open time of malleability, conformation and bonding allows, if the positioning of the piece on the limb is not adequate, the professional who applies it can reposition it and adjust its correct positioning within an estimated time period of 60 to 90 seconds.
- the malleability of the material object of the invention when thermally reactivated allows its edges, borders, corners and edges to be curved shaped, providing greater comfort to the interface areas between the immobilizer and the member of the patient animal.
- the material object of the invention has a certain density of perforations in its structure, together with the presence of special textiles, breathability and waterproofing are provided, ensuring a healthy state of the dermis and other tissues of the limbs of the patient animals, in addition to a lower internal bracing temperature during use.
- the presence of woven and / or nonwoven base textile layers in the subject matter of the invention provides stability in the handling of the product when thermally reactivated.
- the immobilization will not present a risk of dermatological contamination and will be transpirable.
- Thermoplastic material for veterinary use is 100% recyclable.
- the present Privilege invention proposes an innovative thermoplastic material for veterinary use as a breathable orthopedic immobilizer, which consists of the combination of specially treated textile materials with a low melting, thermally-adhesive, easy-molded polymeric structure which provides easy, quick and functional stabilization of immobilized areas after cooling.
- the textile materials of their composition may come from constructions known as woven and / or nonwoven.
- Nonwovens that can be used to manufacture this material are the following:
- All the textile materials listed may contain treatments such as waterproofing, antimicrobial additives and other additives that improve their performance when applied, thus avoiding the generation of diseases of the dermis caused by bacteria, accumulation of moisture and heat, also because it is transpirable.
- thermoplastic polymers which may constitute the polymeric structure of the novel material object of the invention are:
- the polymer structure has the following composition:
- the polymeric structure has the following composition:
- thermoplastic polyester and / or poly (epsilon) -caprolactone polyurethane having an average molecular weight of 80,000 g / mol and between 20% and 50% by weight of polycarbonate and / or polyethylene terephthalate and between 0.001% and 30% by weight of vinyl acetate-ethylene copolymer.
- thermoplastic material for veterinary use as an orthopedic immobilizer can be manufactured with the following arrangements:
- thermoplastic material for veterinary use as an orthopedic immobilizer containing the Nonwoven arrangement + Polymer Matrix Layer + Fabric.
- these polymers After physical mixing, these polymers are melted and rolled onto the spunlaced 100% polyester nonwovens previously and treated with waterproofing and antimicrobial additives and simultaneously receiving the flat polyester and / or cotton fabric on the other side; after passing through calenders with refrigerated cylinders occurs the compacting and stabilization of the material that is later cut and fractioned.
- Its combined textile and polymeric structure enables the material of the invention to be thermally reactivated through a simple, practical and risk-free process of working at elevated temperatures and heating sources which may cause risks to the user, as well as to the animal patient who receives it; it can be used to reactivate heated water at temperatures in the range of 60 ° C to 90 ° C and immerse the material of the innovation in this water for 15 to 30 seconds, after its removal from the heating it is found to be malleable, be applied to the limb to be immobilized from the patient animal such as a textile bandage. Upon cooling to room temperature, the material stiffens and immobilizes the limb and its movements.
