Description

Title of the invention: Panty-type underwear intended for postoperative use

[0001] The invention relates to a panty-type undergarment intended for postoperative use by a patient. State of the art

[0002] Operations involving the vaginal, rectal, abdominal (body lift and others), urinary tracts, as well as cesarean sections and stomas, require heavy follow-up care for patients and necessitate the use of suitable underwear.

[0003] It is particularly known to use postoperative panty-type underwear, which has a lining in the crotch area, the main function of which is to absorb discharges, secretions, bleeding and urinary leaks.

[0004] Document CN202288548 thus proposes a panty with an absorbent base which can be filled with a layer impregnated with therapeutic active ingredients.

[0005] Document TWM628307 also offers a panty with an absorbent base which has an improved structure in terms of leakage as well as an antibacterial function.

[0006] However, products on the market often have limited absorption capacity, both in terms of the volume of liquid to be absorbed and the coverage of the parts of the human body requiring absorption. For example, current underwear does not always allow for the treatment of post-operative effects following a cesarean section, rectal resection, abdominal surgeries (body lift and others), prolapse, or a stoma.

[0007] Furthermore, the materials used are not always suitable for the epidermal areas surrounding the operated area. Indeed, the materials of these types of underwear are not always adapted to scars, whether hypertrophic or not, as well as to local changes in the epidermis. Description of the invention

[0008] Therefore, the invention proposes to remedy all or part of the aforementioned disadvantages by providing an extended absorbent function as well as a restraint function at least in the ventral and dorsal area of ​​the patient.

[0009] The invention relates in particular to a panty-type undergarment intended for postoperative use by a patient, the undergarment defining a first part called ventral and a second part called dorsal, the two parts being made of the same first textile material, the undergarment further comprising a third absorbent part covering at least one area called crotch, characterized in that the third absorbent part extends up to or under the first part called ventral at least along a first distance hi00 so as to cover the pubis of the patient, as well as up to or under the second part called dorsal at least along a second distance hi02 to reach the coccyx of the patient.

[0010] Various embodiments of the invention are provided, incorporating, according to all their possible combinations, the different optional features set out below.

[0011] Preferably, the first textile material allows for a warp and weft weave so as to ensure support at the ventral and dorsal levels.

[0012] According to a certain particular embodiment, the first textile material is composed of a mixture of polyamide and elastane fibers in the ratio of 60 to 70% for polyamide fibers and 30 to 40% for elastane fibers.

[0013] Advantageously, the first textile material is composed of a mixture of polyamide and elastane fibers in the ratio of 66 to 70% for polyamide fibers and 30 to 34% for elastane fibers, preferably in the ratio of 68% for polyamide fibers and 32% for elastane fibers.

[0014] According to a preferred aspect of the invention, the first textile material has a thickness between 0.1 and 0.2 mm.

[0015] According to another preferred aspect of the invention, the first textile material has a density of less than 200 g / m². The textile material Cl may also have barrier properties against UVA and UVB rays. Scars, in fact, have weaknesses in their protection against UVA and UVB rays and can be the site of cellular degeneration leading to skin cancer.

[0016] According to another preferred aspect of the invention, the first textile material also possesses barrier properties against UVA and UVB rays. Scars, in fact, exhibit weaknesses in protection against UVA and UVB rays and can be the site of cellular degeneration leading to skin cancer.

[0017] According to another particular embodiment, the third absorbent part comprises between two and four superimposed layers, with at least one waterproof layer and one absorbent layer, the waterproof layer being disposed on the outside and the absorbent layer being disposed on the inside.

[0018] Preferably, the third absorbent part further comprises a drainage layer intended to cover the absorbent layer.

[0019] More preferably, the waterproof layer consists of a waterproof membrane, and the absorbent layer consists of a blended textile. made of Polyamide / Polyester / Elastane with a mesh weave, and the drainage layer is made of a polyester textile with a mesh weave.

[0020] According to another preferred aspect of the invention, the first ventral part, the second dorsal part, and the third absorbent part are assembled together by gluing or by heat-welding.

[0021] According to yet another particular embodiment, the first ventral part, the second dorsal part are separated and connected to each other at the level of the so-called crotch area by means of the third absorbent part (10).

[0022] According to yet another particular embodiment, the first ventral part and the second dorsal part meet at the crotch area, so that the third absorbent part forms a lining.

[0023] According to yet another particular embodiment, the first so-called ventral part is entirely lined so as to be made up of two layers of the same first textile material.

[0024] According to yet another particular embodiment, the second part, called dorsal, is partially lined so as to be made up of two layers of the same first textile material at the level of its upper part intended to cover the lumbar region of the patient. List of figures

[0035] The embodiments described below are in no way limiting; variants of the invention may include, in particular, a selection of the described features, isolated from the other described features (even if this selection is isolated within a sentence containing these other features), if this selection of features is sufficient to confer a technical advantage or to differentiate the invention from the prior art. This selection includes at least one feature, preferably a functional one without structural details, or with only a portion of the structural details if this portion alone is sufficient to confer a technical advantage or to differentiate the invention from the prior art.

[0036] For the sake of brevity and clarity, the elements bear the same references on the different figures.

[0037] Figures 1 and 2 represent a schematic view of the inside of a panty-type undergarment 1 intended for postoperative use by a patient according to a first embodiment of the invention.

[0038] The undergarment defines a first part called ventral 11 and a second part called dorsal 12, both parts being made of the same textile material CL

[0039] The undergarment further comprises a third absorbent part 10 covering at least one area called the crotch area 13.

[0040] According to the invention, the third absorbing part extends at the level of the first part called ventral 101 at least along a first distance hioi so as to cover the pubis of the patient, as well as at the level of the second part called dorsal 102 at least along a second distance hi02 up to the coccyx of the patient.

[0041] According to a first embodiment, the first ventral part 11 and the second dorsal part 12 meet at the level of the so-called crotch area 13. Thus, the third absorbent part 10 extends along a portion referenced 101, under the first so-called ventral part 11, and extends along a portion referenced 102, under the second so-called dorsal part 12. The third absorbent part 10 thus forms a lining.

[0042] According to a second embodiment represented in figures 3 and 4, which represent a schematic view of the inside or outside of the undergarment 1, the first part, referred to as ventral 11, and the second part, referred to as dorsal 12, are disjointed since only the third absorbent part 10 covers the area referred to as crotch 13. According to this variant, the third absorbent part 10 extends along a portion referred to as 101, up to the first part referred to as ventral 11, and extends along a portion referred to as 102, up to the second part referred to as dorsal 12.

[0043] As can be seen, the postoperative panty according to the invention has an extensive absorption area which makes it possible to protect scars from a wide range of surgical operations (such as anal, vaginal, abdominal (body lift and others), prolapse surgeries, stomas, cesarean sections) and to absorb the discharges following these operations.

[0044] According to an improvement of the invention, the first textile material Cl of the first part, referred to as the ventral part 11, and of the second part, referred to as the dorsal part 12, has a warp and weft weave so as to provide support at the ventral and dorsal levels. A warp and weft weave consists of interlaced threads, the warp threads being parallel to the selvedge of the fabric (along the length of the fabric), and the weft threads being perpendicular to them (along the width of the fabric). It is primarily this type of weave that makes it possible to obtain support along both dimensions (length and width). In the two embodiments shown respectively in Figures 1 and 2, and 3 and 4, the first part, referred to as the ventral part 11, and the second part, referred to as the dorsal part 12, together present a support zone 14 that is both ventral and dorsal.

[0045] Advantageously and in order to reinforce the support, the first part, called ventral 11, is entirely lined so as to be made up of two layers defining a ventral support zone 141 of the same first textile material Cl. This also makes it possible to keep the undergarment spread out on the skin and to prevent it from rolling up on itself.

[0046] Also advantageously, and to further enhance the support, the second, so-called dorsal section 12 is partially lined so as to consist of two layers of the same first textile material Cl in its upper part, which is intended to cover the patient's lumbar region. This dorsal support zone 142 also helps to keep the undergarment spread out against the skin and prevents it from rolling up.

[0047] Warp and weft weaving, which overcomes the drawbacks of mesh weaves, preferentially uses a single, wrapped and balanced yarn (i.e., without torque) from end to end. This limits abrasive effects and makes it an ultra-resistant technical yarn.

[0048] According to a preferred aspect of this improvement, the first textile material Cl is composed of a mixture of polyamide and elastane fibers in the ratio of 60 to 70% for polyamide fibers and 30 to 40% for elastane fibers.

[0049] The composition of this textile material, combined with the warp and weft weave, allows for greater biaxial elongation than a conventional knit, i.e., 20% more elongation. This textile material also exhibits dynamic behavior with significant multidirectional extensions, resulting in freedom of movement in all directions without deformation, and with excellent muscle support.

[0050] Preferably, the first textile material Cl is composed of a mixture of polyamide and elastane fibers in the ratio of 66 to 70% for polyamide fibers and 30 to 34% for elastane fibers, preferably in the ratio of 68% for polyamide fibers and 32% for elastane fibers.

[0051] the textile material Cl can advantageously admit a thickness of between 0.1 and 0.2 mm.

[0052] the textile material Cl can advantageously admit a density of less than 200 g / m2.

[0053] The textile material Cl can also possess barrier properties against UVA and UVB rays. Scars, in fact, exhibit weaknesses in protection against UVA and UVB rays and can be the site of cellular degeneration leading to skin cancers.

[0054] By way of example, textile materials of the AQUATECH® type may be used, which employ elastic covered yarns of the PAGASTIC® type, with a ratio of 68% polyamide fibers and 32% elastane fibers. These fabrics allow for multidimensional stretching, while providing superior muscle support compared to other textile materials of equivalent composition. As a result, these fabrics adapt to the movements of muscles and joints, which are naturally accompanied by multidirectional deformation of the textile. For example, and as shown in Figures 6 and 7, a multidirectional elongation of 120% is achieved without resistance.

[0055] The density of AQUATECH® type textiles ranges from 50 to 230 g / m², making these fabrics approximately 35% lighter than conventional fabrics used for postoperative underwear. As shown in [Fig. 8], these fabrics have a density of around 120 g / m². This 35% weight reduction is This is especially true when the post-operative briefs are used in aquatic environments. Indeed, textile materials such as AQUATECH® are also compatible with aquatic use, which is favored in certain post-operative care programs such as spa treatments, pool rehabilitation, etc.

[0056] AQUATECH® type textiles also exhibit significant resistance to abrasion and chemicals, as they withstand standard Martindale tests such as the FS ISO 12947-2 test, with no damage observed after 500,000 cycles (see [Fig. 9]). Regarding chlorine resistance, after 60 hours of immersion, AQUATECH® type textiles lose only 17% of their elasticity, compared to 70% for a conventional mesh structure.

[0057] AQUATECH® type textile materials have an ultra-fast drying quality, i.e. 3 minutes compared to 10 to 17 minutes for mesh according to standard NF G07 166.

[0058] Textile materials of the AQUATECH® type also have the advantage of being breathable since air and water slide over these materials without penetrating the fibers.

[0059] AQUATECH® type textile materials offer very high performance UV protection, since the measurement of the UV protection index according to the AS / NZS 4399 standard produces a score of over 700 UPF, which makes it easy to meet the highest level of protection, i.e. 50+.

[0060] Regarding the third absorbent part 10, its textile material CIO preferably comprises between two and four superimposed layers, with at least one waterproof layer ClOa and one absorbent layer ClOb, the waterproof layer being arranged on the outside and the absorbent layer being arranged on the inside.

[0061] Preferably, the third absorbent part CIO further comprises a draining layer ClOc intended to cover the absorbent layer.

[0062] As represented in a preferred embodiment in [Fig.5], the textile material CIO composing the third absorbent part comprises a waterproof layer ClOa consisting of a waterproof membrane, an absorbent layer ClOb consisting of a textile blend of Polyamide / Polyester / Elastane following a mesh-type weave, and a draining layer ClOc consisting of a polyester textile following a mesh-type weave.

[0063] The polyamide and elastane of the absorbent layer ClOb give said layer its absorbent character, while the standard polyester “cool max” gives said layer its breathable and quick-drying character.

[0064] The third absorbent part 10 thus keeps the scars dry to facilitate healing, while absorbing fluids. The absorption capacity is 25 to 35 ml per day.

[0065] In order to preserve the skin and to seal the boundaries between the third absorbent part 10, the first so-called ventral part 11 and the second so-called dorsal part 12, the assembly between the third absorbent part 10, and the first and second parts is carried out by gluing or by heat-welding.

[0066] All CIO and Cl textile materials are OEKOTEX 100 and REACH certified. The OEKO-TEX Standard 100 label is a quality label, also known as “Confidence in Textiles” in France, which guarantees the safety of textiles or products used during the production process, for humans and the environment. REACH certification is based on a European regulation (Regulation No. 1907 / 2006) which came into force in 2007 to ensure the safe manufacture and use of chemical substances in European industry.

[0067] In summary, the first ventral part 11 and the second dorsal part 12 allow, by virtue of the first textile material Cl constituting them, to:

[0068] protect postoperative abdominal and lumbar scars, particularly against friction and UV radiation (scars have weaknesses in protection against UVA and UVB rays and can be the site of cellular degeneration leading to skin cancer),

[0069] slow down the formation of hypertrophic scars,

[0070] to protect old and painful hypertrophic scars, particularly against friction and UV radiation,

[0071] keep the epidermis and scars dry

[0072] The third absorbent part 10, due to its constituent textile material CIO, allows for:

[0073] absorb menstrual or postpartum bleeding or bleeding resulting from certain gynecological operations,

[0074] absorb menstrual and urinary incontinence,

[0075] relieve and protect perineal scars (episiotomies, perineum, prolapse,...), and anal scars (hemorrhoidal resection,...).

[0076] Thus, the underwear that is the subject of the invention can also take the form of a thong, a boxer short or a one-piece bodysuit.

[0077] Of course, the invention is not limited to the examples just described and many modifications can be made to these examples without departing from the scope of the invention. Nomenclature
