Definitions

  • This Utility Model Patent application concerns an IMPROVEMENT IN A DISPOSABLE DIAPER WITH A WASTE CONTAINMENT SYSTEM BY ISOLATION OF THE EDGES, the object of this patent, which constitutes a physical blocking system in geriatric diapers to prevent contamination of the urethra by fecal material; its field of application is the health area, personal hygiene articles for the elderly (female public), more specifically disposable sanitary pads.
  • a diaper is an absorbent, usually disposable, article designed to be used by humans for the containment and collection of bodily waste (urine and feces).
  • a diaper generally consists of several layers of materials, each with specific functions, and as standard they have: a top sheet, an absorbent core, a waterproof back sheet and a fastening system on the side flaps.
  • the top sheet is a soft, comfortable layer that lies next to the individual's skin and helps keep them dry by absorbing moisture.
  • the absorbent core is made from a blend of fluff pulp and polymer particles, which can absorb and retain a large amount of liquid.
  • the back sheet is a waterproof layer that prevents any leakage, and the fastening system secures the diaper so that it fits snugly around the individual.
  • the urethra is more susceptible to contamination by fecal matter, which not only generates the possibility of skin irritation but also susceptibility to urinary infections.
  • the market lacks appropriate technology for women ⁇ with a system that prevents fecal matter from coming into contact with the urethra.
  • This diaper model also features an additional fecal containment system consisting of two semicircular flaps, diametrically opposed, located in the center of the diaper, on the lateral ends of the Containment Barrier. This system reinforces the physical seal, preventing contamination of the urethra by fecal material that emerges from the sides of the diaper.
  • the geriatric diaper with feces containment system will work as follows: (i) the film protecting the adhesive of the feces containment barrier on the inside of the diaper is removed; (ii) the containment barrier is then glued to the perineum region of the patient/user/consumer; finally, (iii) the film protecting the adhesives on the side flaps closing the diaper is removed, securing it to the patient and adjusting the anatomical elastic folds on the user's legs.
  • the main differential of the claimed invention is a feces containment system, located on the inside of the diaper, characterized by a soft protuberance 5 to 10 mm high by 10 mm wide, padded with 45 to 90% LLDP foam and 10 to 55% polypropylene, coated on the upper part (which will be in contact with the perineum region) with an adhesive dressing composed of a semipermeable film of polyurethane and carboxymethyl cellulose polymer (CMC).
  • CMC carboxymethyl cellulose polymer
  • the geriatric diaper with fecal containment system is made using the traditional diaper manufacturing system, with the exception of the application of the containment barrier, which will require the introduction of an additional gluing process using pressure and heat.
  • the adhesive dressing composed of a semipermeable film of polyurethane and carboxymethyl cellulose (CMC) polymer is indicated as primary coverage for lesions with light to moderate exudation and as protection for intact skin.
  • CMC carboxymethyl cellulose
  • the solution to this need involves introducing a flap system associated with a small, non-absorbent adhesive pad to be placed on the perineum, physically separating the urethra from the anal region.
  • This pad has a system of adhesive elastic folds suitable for skin, including the skin of the elderly.
  • the geriatric diaper with fecal containment system is made using the traditional diaper manufacturing system, with the exception of the application of the containment barrier, which will require the introduction of an additional gluing process using pressure and heat.
  • the inner layer, outer layer and other components are added around the absorbent core.
  • the inner layer made of soft and absorbent materials, is placed directly on the core to ensure that the user's skin remains dry.
  • the outer layer made of waterproof material, is applied on top to prevent leaks.
  • elastic bands and anti-leak barriers are inserted into the sides of the diaper.
  • the containment barrier is inserted after all the internal elements of the diaper have been formatted and is applied using a heat and pressure welding process applied to the perimeter of the barrier (which has the shape of a rectangular cushion, with polypropylene or polyethylene flaps that fuse with the internal lining when pressure and heat are applied in a specific manner).
  • Cutting and Modeling The diapers are cut and molded into their final shape using high-precision cutting machines. Depending on the diaper model, specific adjustments can be made, such as anatomically shaped cuts.
  • Fixing the Adhesive Tapes The adjustable adhesive tapes are applied to the sides of the diaper to allow it to be fixed and adjusted around the user's waist.
  • Figure 1 shows the geriatric diaper, open, with its internal part exposed, where it is possible to see (1) the flap system and (2) adhesives for closing the diaper, (3) the internal lining of the diaper (absorbent core) – composed of cellulose pulp and superabsorbent polymers, (4) the ergonomic elastic – which allows adjustment and comfort around the legs, (5) the internal elastic sealing pleats and (6) external elastic sealing pleats – which prevent the leakage of liquids/waste through the sides of the diaper, (7) adhesive and non-absorbent pad with (8) adhesive to be glued to the perineum.
  • Figure 2 illustrates the longitudinal section of the diaper, revealing the protuberance represented by the (7) adhesive and non-absorbent pad with (8) adhesive to be glued to the perineum, as well as the (3) internal lining of the diaper (absorbent core), and the (9) external layer (external lining) consisting of a polyolefin film.
  • Figure 3 shows the diaper open, with its external part exposed, where it is possible to see the (9) external lining, the (4) ergonomic elastic, which serves to tighten the part of the diaper close to the inner part of the thighs, helping the diaper to follow the shape of the user's body and also preventing leaks from the sides of the diaper; finally, it indicates the (1) flap system with (2) adhesive closure.
