AI Technical Summary
Existing medical-surgical compresses are poorly absorbent, costly, generate hospital waste, and release lint and particles, contributing to infections, despite existing patents lacking innovative solutions for these issues.
A compress model combining 70% viscose and 30% polyester layers sealed by ultrasound, with a wrinkled surface and radiopaque thread, providing high absorption, minimal particle release, and enhanced visibility.
The solution offers efficient fluid absorption, low particle release, improved visibility, and increased resistance, addressing the limitations of conventional compresses while reducing waste and infection risk.

Abstract
Description
[0001] “CONSTRUCTION DISPOSITION APPLIED TO COMPRESSES FOR CURATIVE, MEDICAL, SURGICAL AND RELATED PROCEDURES”. Field of the invention
[0001] The subject matter of the invention patent application belongs to the technical sector of auxiliary devices for carrying out curative and medical procedures in general, including surgical or non-surgical ones. Fundamentals of the invention
[0002] As is known mainly by all those who work directly or indirectly in activities related to the health sector, nursing, medicine, and related fields, compresses (object) are typically sterile fabric fractions intended for dressings and / or in surgeries and medical procedures in general, aiming at the absorption of liquids, blood, and other secretions, in addition to acting as a shield for viscera, tissues, and similar bodily elements, and are widely used in cavity surgeries, as well as on raw surfaces. State of the art / existing problems
[0003] It is known that the vast majority of medical-surgical compress models are usually marketed as 100% cotton fabric pieces, which are poorly absorbent and require the use of a significant number of units in procedures. This, in addition to being more expensive and costly, also ends up producing much more hospital waste, aggravated by the release of residue, lint, and particles, whose condition is inappropriate for their respective purposes, as they can contribute to the onset and / or worsening of generalized infections. From the state of the art
[0004] In order to assist and clarify the state of the art, some surveys were carried out that pointed to the existence of patent documents dealing with relatively similar solutions, without evidencing, however, the innovative, utilitarian, constructive and functional characteristics intrinsic to the object of the patent application in question, and the processes listed below can be cited as an example: - BR102018071533: related to a model of gauze compress consisting of a non-adherent mesh of cellulose acetate impregnated with extra virgin coconut oil, developed more specifically to act as a primary dressing, aiming at hydrating wounds, which, according to its inventor, maintains the ideal moist environment for healing;- BR112014013337: refers to a hemostatic compress comprising a bioabsorbable scaffold material, lyophilized powders of thrombin, fibrinogen and meltable binder, for hemostatic treatment or sealing at a wound site; - BR102012032924: presents a computerized surgical compress consisting of a sewn-in label that can be identified via radiofrequency and remote sensors, preventing foreign bodies from being left inside the patient, also enabling control of the quantity of compresses used in surgical procedures;- BR112012011049: brings a reusable intelligent textile complex for medical use, washable protective medical tracing and reusable washable compress made with said complex, intended to keep patients with general incontinence dry, through an outer upper layer composed of a double-layer honeycomb mesh fabric of thermoplastic fiber, where the exposed layer is a soft-touch fabric and the inner layer is a lace bonding fabric, both sides being joined by a zigzagging monofilament that keeps them separated from each other; a set of inner layers comprising: a first layer of a lace bonding thermoplastic fiber fabric; a second layer formed by a set of at least three plies, each composed of low-density non-woven material (geotextile) composed of polypropylene fibers encapsulated in polyester yarn, said plies being related with a continuous filament yarn;a third layer of at least one fabric composed of a high-density non-woven material (geotextile) of artificial cellulose fibers, and an outer lower layer composed of a waterproofed continuous thermoplastic fiber jersey; - BR202013031858: deals with an improvement introduced in a constructive arrangement in a gauze compress, defined by cotton threads processed on a loom, producing interlacings finished in a tissue structure in a sinusoidal weave combined with curvilinear interlacings. Object of the invention;
[0005] Regarding the subject matter of the patent application in question, a compress model is presented that stands out from other known, conventional and existing models on the market due to the combination and arrangement of the different materials comprised by it, resulting in a super absorbent surgical compress in non-woven and viscose and polyester with two or more layers, which do not release residue, lint or excess particles, also bringing a double safety handle designed to facilitate its handling, solving, in a practical, economical and effective way, the main problems reported above, in addition to adding the following advantages and benefits: - highly efficient absorption of fluids; - very low release of particles during use; - excellent visibility in radiological examinations; - reinforced layers that increase resistance; - ultrasound sealing that ensures greater safety; - wrinkled surface for better absorption;- material free of unwanted particles; - high resistance for use in surgical procedures; - design designed for efficiency and safety. Description of the invention;
[0006] The object herein disclosed constitutes a compress for use in healing, medical, surgical and similar procedures, obtained in two or more layers composed of 70% viscose and 30% polyester, sealed by ultrasound and with wrinkled surfaces for better absorption, in addition to equipped with a radiopaque thread and added a safety strap, and can be made available to the market in the most varied formats and dimensions necessary and appropriate, combining the following characteristics: - composition: non-woven (viscose 70% + polyester 30%); - absorption: superabsorbent; - visibility: radiopaque thread; - color: white (allows variations); - layers: two or more layers (e.g., weights of 130g / m2, 170g / m2, etc.); - sealing and fixation: performed by ultrasound; - surface: wrinkled; - particle release: absent or minimal; - high strength and durability. Brief description of the drawings
[0007] In order to better understand the constructive, functional, utilitarian and innovative characteristics of the subject matter of the patent application disclosed herein, the images listed below are attached, in which: - Figure 1 illustrates a schematic view of a model of the compress in question, exemplifying it in three layers; - Figure 2 shows the said compress in perspective view. Detailed characteristics of the invention
[0008] It presents a compress (1) for use in healing, medical, surgical and similar procedures, obtained in two or more layers (C) composed of 70% viscose and 30% polyester, sealed by ultrasound and with wrinkled surfaces (2) for better absorption, in addition to being equipped with a radiopaque thread (3) and added with a safety strap (4), making it opportune to emphasize that regardless of the description and representation of the compress model revealed here, nothing prevents it from having its characteristics, layouts and technical capabilities changed, given the possibility of updating or varying versions, maintaining or even improving the performance achieved, logically without straying from the spirit and scope of what is now explained, therefore ending in an innovation of great utility and which meets the essential requirements of novelty, inventive step and industrial application necessary for the protection now required.
