発明の分野
本発明は使用中、装着者に面することを意図される第一表面、及び使用中、装着者から離れて面することを意図される第二表面を有する解剖学的に造形された吸収体を含み、かつ陰唇内に装着されるように設計される吸収性衛生保護手段に関する。
【0002】
背景技術
月経と関連して使用するための極めて多くの様々なタイプの吸収性保護手段がある。最も一般的なものは衛生ナプキン及びパンティライナーであり、それらは体の外側に装着されかつほとんどの場合において装着者のパンツに固定される吸収性保護手段であり、放出された月経液を収集しかつ吸収する。タンポン又は液体収集配置の形の内部衛生保護手段もまた存在し、それは使用者の膣の中に挿入される。今まで市場に浸透していない第三の分類の衛生保護手段は陰唇内保護手段として知られるものであり、それは装着者の陰唇の間に完全に又は部分的に装着される。かかる保護手段は他のタイプの衛生保護手段の両方の利点を併せ持つ。即ち、陰唇内保護手段は内部保護手段のように小さくて装着しても目立たない。さらに、陰唇内保護手段は膣の中に挿入されず、それを多くの装着者は有利であると考える。
【0003】
しかしながら、従来公知の陰唇内保護手段は多数の欠点を有し、それはそれらの良好な特性にもかかわらず、それらの商業的成功を達成するようには至っていない。一つの問題は保護手段を使用中適所に保持することである。もし保護手段が装着者のパンツにおいて接着剤などによって従来の方法で固定されるなら、それは装着者が動くときにパンツとともに動くだろう。これは、装着者の体と密着した位置から動き、その密着性を失う危険があることを意味する。陰唇内保護手段は装着者の陰唇間に収容されるように相対的に小さくかつ短く作られなければならないので、保護手段の小さな動きであっても保護手段を越える漏れの危険が劇的に増大する。しかしながら、もし保護手段が使用位置で全く固定されないなら、装着者の体と下着の間に隙間がある場合、それが落下又は移動してしまう危険がある。それはまた、もしトイレに行くときに保護手段を失い、例えばトイレ中に落とすことになれば欠点である。
【0004】
別の主要な問題は従来入手可能であった陰唇内保護手段が装着を不快に感じることである。これは陰唇間の領域が摩擦及び圧力に対して極めて敏感であり、それゆえ快適な保護手段に対する要求と適切な吸収能力及び漏出安全性に対する条件を組合わせることが実質的に不可能であることが証明された。
【0005】
それゆえ快適に装着できて使用中適所にしっかりと留まり、さらに満足のいく漏出防止性を与える、効果的に機能する陰唇内衛生保護手段に対する要求がなお存在する。
【0006】
しかしながら、本発明によって、陰唇内使用のための従来公知の衛生保護手段が被っていた欠点及び問題が本質的に除去された、冒頭で言及されたタイプの吸収性衛生保護手段が製造される。本発明に従って作られた製品は製品の吸収体が予め形成された少なくとも部分的に脱水されたヒドロゲルからなり、かつ第一表面上に配置されたカップ形状部分と細長い把手形状部分を有するスプーンの形状であり、把手形状部分が予備形成によって、湿潤すると膨潤して保護手段の第一表面上で隆起部分を形成する部分を含むことを特徴とする。
【0007】
衛生保護手段の特別なデザインの結果として、使用中の保護手段の特に良好な解剖学的適合、結果としての良好な保持、並びに高い漏出安全度が達成される。さらに、衛生保護手段は装着者の体に対して最初から正しく位置されることを確実にされる。この関連において、衛生保護手段は装着者のクリトリス上にカップ形状部分を、膣開口上に細長い把手部分を伴って配置される。このようにしてもたらされうる位置決めの正確性は隆起部分が装着者の体に対して正しい場合で形成されることを確実にする。
【0008】
本発明による吸収性衛生保護手段は相対的に小さく、この点に関して好ましくは約8.5cmを越えない長さを持つので、衛生保護手段が使用後、保護手段の除去のための把持手段を含むなら有利になりうる。この関連において、好適な把持手段は把持ループ、除去紐、把持タブなどである。把持手段は衛生保護手段の残りと同じ材料から作られることができ、それゆえその一体部分を構成することができる。あるいは把持手段は衛生保護手段に固定される別個の構成要素であることができる。この関連において、把持手段はヒドロゲル中に成形されることができ、又は衛生保護手段に接着、溶接又は機械的に固定されることができる。
【0009】
把持タブ又は把持ループの形の把持手段はクリトリス及び膣開口上への衛生保護手段の適用を容易にするために使用されることもできる。ヒドロゲルは装着者の粘膜を刺激しない材料から作られ、この点に関してビニルアルコール、ポリアクリレート、ポリメタクリレート、ポリエチレンオキサイド、ポリサッカライド、アクリルアミド、ビニルピロリドン、ポリエーテル、アミノ酸又はウレタンに基づくポリマー、及びそれらの混合物、コポリマー及び誘導体を含むことができる。
【0010】
衛生保護手段が型中で成形することによって製造されるとき、ヒドロゲルの第二表面上に皮膚状表面が形成される。かかる皮膚状表面は液体が保護手段から漏出するのを防止する液体バリヤーとして機能する。あるいは、プラスチックフィルムの形の別個の液体ブロッキング層、又は液体ブロッキング材料の被覆を衛生保護手段に与えることももちろん可能である。
【0011】
吸収性衛生保護手段は好適には膨潤されたヒドロゲルを成形することによってカップ形状前部分及び隆起部分を持つ細長い後部分を有する解剖学的に適応された形状を付与される。造形された膨潤ヒドロゲルは完全に又は少なくともヒドロゲルが吸収性衛生保護手段において使用中湿潤を受けたときに液体を再吸収できるような範囲に脱水される。生じた保護手段は脱水後、すぐに使用できる。
【0012】
保護手段が使用されるとき、ヒドロゲルは体液を吸収し、次いで後隆起部分を有するその元の予め決められた形状に膨潤するだろう。同時に、液体吸収はヒドロゲルの表面が粘着性になることを意味し、それは優しくて快適な方法で装着者の陰唇間の粘膜に対する保護手段の容易な接着を可能にする。吸収中、吸収材料中に減圧も生じ、それは装着者の体に対して保護手段を保持することに寄与する。粘着質の表面は使用中、湿り、それは結果として装着者の粘膜が乾燥する危険を除去する。吸収製品の表面から液体を迅速に運び去るように設計された従来の表面材料及び従来の繊維吸収材料が使用されるとき、粘膜の乾燥はかなり問題である。
【0013】
さらに、粘膜の如き敏感な体の表面と接触している吸収製品上の乾燥表面は摩擦及び他の機械的刺激の増大した危険に導く。
【0014】
湿潤ヒドロゲルの接着能力は衛生保護手段の解剖学的に適応された形状とともに、装着者の粘膜を摩擦したり又は刺激したりせずに保護手段を使用中、適所にしっかりと保持する。顕著に良好な適合及び信頼性のある取り付けは漏出安全性を損なわずに保護手段を小さくかつ目立たないように設計することができる。これは保護手段が従来の繊維吸収材料から本質的になる従来公知の陰唇内保護手段より嵩ばらず、装着するのに不快感が少ないことを意味する。
【0015】
より大きな吸収能力が要求される場合、又は予想した体液の流れが相対的に大きい場合、衛生保護手段の液体吸収能力は保護手段の隆起部分内に高い液体吸収速度を持つ吸収材料を配置することによって増大されることができる。好適なかかる吸収材料は吸収フォームである。内部吸収材料は衛生保護手段の第一表面上のヒドロゲル中の開口を通して液体を受けるために露出されていることが好適である。
【0016】
別の例によれば、衛生保護手段は隆起部分を伴って設計されることができ、その隆起部分には一以上のキャビティ又は溜めが配置され、それは衛生保護手段の第一側上の体液の流入のために開放している。ヒドロゲルによってすぐに吸収されることができない体液は溜め中に一時的に捕獲されることができ、次いでヒドロゲルによって徐々に吸収されることができる。この例は隆起部分中に内部吸収体を有する前述された例の単なる変形である。本発明による吸収性衛生保護手段は女性装着者の性器領域において解剖学的構造に密接に従うように設計されることが好ましい。この関連において、スプーン形状部分は15〜20mmの長さを有し、把手部分は55〜65mmの長さを有することが好ましい。もし衛生保護手段が隆起部分を与えられるなら、これは保護手段の縦方向で測定すると約10mmのスプーン形状部分からの距離で位置されることが好ましい。隆起部分は好適には30〜35mmの長さを有し、それは15〜20mmである縦方向の範囲を有する隆起部分の後に本質的に平坦な部分を残す。衛生保護手段の全長は約85mmであることが好適である。衛生保護手段の幅、即ち横方向の範囲はスプーン形状部分の最も幅広い部分において好適には5〜20mm、好ましくは10〜15mmである。把手形状部分は好適には20mmの最大幅を有し、隆起部分の幅は約10mmである。
【0017】
本発明による保護手段の一つの利点はその小さなサイズ及び大きなフレキシビリティによって保護手段を使用後、流し去ることができることである。使用した保護手段はそれゆえ簡単で便利な方法で廃棄されることができる。
【0018】
本発明による衛生保護手段は例えば夜の使用のために、体液の流れがきついとき又は増大した漏出安全性が望ましいとき、パンティライナー又は衛生ナプキンと組合わせて使用されることができる。
【0019】

発明を実施するための方式
図1,2及び3に示された衛生保護手段1はヒドロゲルから作られ、それは使用中、装着者の前方に面することを意図されかつ装着者の体に対してカップ形状部分で装着者のクリトリス上に配置される前方のカップ形状部分2を伴って、示されたスプーン形状に成形される。衛生保護手段はまた、使用中、装着者の後方に面しかつ膣開口上に位置され会陰に向かって後方に延びる細長い後部分3を有する。
【0021】
衛生保護手段1は使用中、装着者から離れて面することを意図される下部表面4を有する。この関連において、下部表面は好適には液体不透過性であり、プラスチックフィルムの如き液体不透過性材料の層、又は液体不透過性材料の被覆からなることができる。あるいは、衛生保護手段は本質的に液体不透過性の表面が下部表面上に形成されるような方法で製造されることができる。
【0022】
衛生保護手段1はまた、保護手段の使用時に装着者に面することを意図される上部表面5を有する。上部表面5は液体を受けとり、それを衛生保護手段中に受け入れる。この目的のため、上部表面は親水性又は疎水性材料の開放した表面層によってカバーされることができる。もし液体受入表面がヒドロゲル表面からなるなら、わずかに粘着した、接着性でかつ湿った表面が吸収中に得られ、それは一方では装着者の粘膜に優しく、他方では衛生保護手段が使用中、適所にしっかり留まることを確実にする利点を有する。
【0023】
衛生保護手段が使用中、湿潤されるとき、ヒドロゲルは液体を吸収して膨潤し、それによって後部分3は図2及び3に示されたように隆起部分6を形成する。隆起部分6の形状及びサイズは膨潤されたヒドロゲルが解剖学的に適応された形状に成形されるときに衛生保護手段の製造中に既に決定されている。ヒドロゲルが膨潤するとき、その表面は湿潤してわずかに粘着し、それは装着者の体への保護手段の柔軟で快適な接着を与え、装着者の陰唇間の粘膜を湿った状態に保つ。これは粘膜の乾燥及び摩擦の危険を除去する。膨潤されたヒドロゲルは柔らかくてフレキシブルであり、しかも弾性的である。それは本発明による衛生保護手段が装着されたときに装着者に対して実質的に知覚されないことを意味する。保護手段の柔らかい構造によって、保護手段は装着者の体に従ってそれ自身造形し、圧力又は鋭いコーナーの侵入などの形の不快感が避けられる。吸収中にヒドロゲルに起こる液体の減圧はまた、前述のように衛生保護手段の接着能力に寄与し、それゆえ使用中、保護手段の保持のために有利である。
【0024】
本発明による衛生保護手段は湿潤後、柔らかくフレキシブルで粘着性を持つようになるので、使用後、保護手段の除去を容易にするある形の把持部材を与えられるなら有利である。図4には把持ループ7の形のかかる把持部材の一例が示されている。把持ループ7はヒドロゲルから形成されることができ、この関連において衛生保護手段1自体とともに成形されることができる。あるいは、把持ループ7は別個の構成要素であることができ、例えば紐ループ、プラスチックバンド、金属ループなどからなることができ、それは衛生保護手段上にしっかりと成形、接着又は溶接される。
【0025】
図5及び6は把持部材のさらなる例を示す。図5は衛生保護手段1を示し、それに二つの把持紐8が成形されている。もちろん一つだけの把持紐8を使用すること及び別の方法で、例えば溶接又は接着によって紐(単数又は複数)を固定することができる。また衛生保護手段に把持紐を結ぶことによってそれを固定することも考えることができる。かかる固定は細長い後部分3の端に貫通穴(図示せず)を有する衛生保護手段を与え、その穴を通して把持紐を結ぶことによって実施されることが好適である。
【0026】
図6は把持タブ9の形の把持部材を示す。把持タブ9は前述の把持部材と関連して示されたものに対応する方法で衛生保護手段1とワンピースで成形されることができ又は成形、接着又は溶接によって衛生保護手段に固定される別個の材料から作られることができる。
【0027】
図6に示された衛生保護手段1は吸収に関する限り、隆起部分6がヒドロゲルの内側に配置される吸収体10を含み、かつ周囲のヒドロゲルより高い吸収速度を有する材料から作られる点において図1〜5に示された保護手段と異なる。かかる例は衛生保護手段1が強い体液の流れ及び/又は相対的に多量の液体を受けることを予想されるとき好適である。内部吸収体10のために使用されることができる材料は繊維材料、吸収フォーム、繊維材料と超吸収材料の混合物などである。内部吸収体10を持つ本発明による衛生保護手段は吸収前、保護手段の細長い後部分3において小さな隆起部分6を既に有する。しかしながら、湿潤すると、隆起部分6はさらに膨潤し、図6に示された予め決められた形状及びサイズをとる。
【0028】
体液が内部吸収体10によって迅速に吸収されることができるためには、内部吸収体はヒドロゲル中の開口11を通して体液の流れに暴露される。
【0029】
一例(図示せず)によれば、衛生保護手段1の隆起部分6はヒドロゲル中に溜め又はキャビティを与えられることができ、その溜め又はキャビティにおいて液体がヒドロゲルによって吸収されうる前に液体を一時的に収集することができる。かかる例は図6に示されたものと同様であるが、内部吸収体10を持たない。
【0030】
示された様々な把持部材7,8,9はもちろん相互交換可能であり、衛生保護手段1の残りのデザインにかかわらず、把持部材のタイプを自由に選択することができる。

FIELD OF THE INVENTION The present invention is an anatomically shaped having a first surface intended to face the wearer during use, and a second surface intended to face away from the wearer during use. Absorbent sanitary protection means comprising an absorbent body and designed to be worn in the labia.
[0002]
BACKGROUND There are numerous different types of absorbent protection means for use in connection with menstruation. The most common are sanitary napkins and panty liners, which are absorbent protective means that are worn on the outside of the body and most often secured to the wearer's pants, to collect the released menstrual fluid. And absorb. There is also internal hygiene protection in the form of a tampon or liquid collection arrangement, which is inserted into the user's vagina. A third class of hygiene protection measures that have not hitherto penetrated the market are known as intralabial protection measures, which are worn completely or partially between the wearer's labia. Such protection measures combine the advantages of both other types of sanitary protection measures. That is, the intralabial protection means is small and inconspicuous even when worn, like the internal protection means. In addition, the intralabial protection is not inserted into the vagina, which many wearers find advantageous.
[0003]
However, the previously known intralabial protection measures have a number of disadvantages, which, despite their good properties, have not yet achieved their commercial success. One problem is to keep protective measures in place during use. If the protective means is secured in the wearer's pants in a conventional manner, such as by an adhesive, it will move with the pants as the wearer moves. This means that the user moves from a position in close contact with the body of the wearer, and there is a risk of losing the close contact. Since the intralabial protective means must be made relatively small and short so as to be accommodated between the wearer's labia, the risk of leakage across the protective means increases dramatically even with small movements of the protective means I do. However, if there is no gap between the body of the wearer and the underwear, there is a risk that it will fall or move if the protection means is not fixed at all in the position of use. It is also a disadvantage if you lose your protection when you go to the toilet, for example if you drop it in the toilet.
[0004]
Another major problem is that the conventionally available intralabial protection means feel uncomfortable to wear. This means that the area between the labia is extremely sensitive to friction and pressure, so that it is virtually impossible to combine the requirements for comfortable protective measures with the requirements for adequate absorption capacity and leakage safety. Was proved.
[0005]
There is therefore still a need for an effectively functioning intralabial hygiene protection means that can be worn comfortably, stays in place during use, and provides more satisfactory leakage protection.
[0006]
However, the present invention produces an absorbent sanitary protection of the type mentioned at the outset, which essentially eliminates the drawbacks and problems encountered by previously known hygiene protections for intralabial use. A product made in accordance with the invention comprises a spoon having a cup-shaped portion and an elongated handle-shaped portion disposed on a first surface, the product comprising an at least partially dehydrated hydrogel with a preformed absorbent article. Wherein the handle-shaped portion comprises, by preforming, a portion which swells when wetted and forms a raised portion on the first surface of the protection means.
[0007]
As a result of the special design of the hygiene protection means, a particularly good anatomical fit of the protection means during use, a resulting good retention and a high degree of leakage safety are achieved. Furthermore, it is ensured that the hygiene protection means is correctly positioned from the start with respect to the wearer's body. In this connection, the hygiene protection means is arranged with a cup-shaped part on the wearer's clitoris and with an elongated handle part on the vaginal opening. The positioning accuracy that can be provided in this way ensures that the raised portions are formed in the correct case for the wearer's body.
[0008]
The absorbent sanitary protection means according to the invention is relatively small, and preferably has a length not exceeding about 8.5 cm in this respect, so that the sanitary protection means comprises gripping means for removal of the protection means after use. Then it can be advantageous. In this context, suitable gripping means are gripping loops, stripping cords, gripping tabs and the like. The gripping means can be made from the same material as the rest of the hygiene protection means and can therefore constitute an integral part thereof. Alternatively, the gripping means can be a separate component fixed to the sanitary protection means. In this connection, the gripping means can be molded into the hydrogel or can be glued, welded or mechanically fixed to the sanitary protection means.
[0009]
The gripping means in the form of gripping tabs or loops may also be used to facilitate the application of hygiene protection on the clitoris and vaginal opening. Hydrogels are made from materials that do not irritate the wearer's mucous membranes, and in this regard, polymers based on vinyl alcohol, polyacrylates, polymethacrylates, polyethylene oxides, polysaccharides, acrylamides, vinylpyrrolidone, polyethers, amino acids or urethanes, and the like. Mixtures, copolymers and derivatives may be included.
[0010]
When the hygiene protection means is manufactured by molding in a mold, a skin-like surface is formed on the second surface of the hydrogel. Such a skin-like surface functions as a liquid barrier to prevent liquid from leaking out of the protective means. Alternatively, it is of course possible to provide the hygiene protection means with a separate liquid blocking layer in the form of a plastic film, or a coating of a liquid blocking material.
[0011]
The absorbent hygiene protection means is preferably provided with an anatomically adapted shape having a cup-shaped anterior portion and an elongated posterior portion with a raised portion by molding a swollen hydrogel. The shaped swelled hydrogel is completely or at least dehydrated to such an extent that the hydrogel can resorb liquid when subjected to wetness during use in absorbent hygiene measures. The resulting protective means can be used immediately after dehydration.
[0012]
When a protective means is used, the hydrogel will absorb body fluids and then swell to its original predetermined shape with posterior ridges. At the same time, liquid absorption means that the surface of the hydrogel becomes sticky, which allows for easy adhesion of the protective means to the mucous membrane between the labia of the wearer in a gentle and comfortable manner. During absorption, a reduced pressure also occurs in the absorbent material, which contributes to holding the protective means against the wearer's body. The sticky surface gets wet during use, which eliminates the risk of drying out the wearer's mucous membrane. Drying of mucous membranes is a significant problem when conventional surface materials and conventional fiber absorbent materials designed to rapidly carry liquids away from the surface of the absorbent product are used.
[0013]
In addition, dry surfaces on absorbent products in contact with sensitive body surfaces, such as mucous membranes, lead to increased risk of friction and other mechanical irritation.
[0014]
The adhesive capacity of the wet hydrogel, together with the anatomically adapted shape of the hygiene protection means, keeps the protection means firmly in place during use without rubbing or irritating the wearer's mucous membranes. A significantly better fit and a reliable mounting allow the protection to be designed to be small and unobtrusive without compromising leakage safety. This means that the protection means is less bulky and less discomforting to wear than conventionally known intralabial protection means consisting essentially of conventional fiber-absorbing materials.
[0015]
If greater absorption capacity is required or the expected body fluid flow is relatively large, the liquid absorption capacity of the sanitary protection means should be to place an absorbent material with a high liquid absorption rate in the raised part of the protection means. Can be increased by A preferred such absorbent material is an absorbent foam. The inner absorbent material is preferably exposed to receive liquid through an opening in the hydrogel on the first surface of the sanitary protection means.
[0016]
According to another example, the sanitary protection means can be designed with a raised part, in which the raised part is arranged with one or more cavities or reservoirs, which are adapted for the bodily fluids on the first side of the sanitary protection means. Open for inflow. Body fluids that cannot be immediately absorbed by the hydrogel can be temporarily captured in the reservoir and then gradually absorbed by the hydrogel. This example is a mere modification of the previous example with an internal absorber in the raised portion. The absorbent hygiene protection according to the invention is preferably designed to closely follow the anatomy in the genital area of the female wearer. In this connection, the spoon-shaped part preferably has a length of 15-20 mm and the handle part has a length of 55-65 mm. If the sanitary protection means is provided with a raised part, it is preferably located at a distance from the spoon-shaped part of about 10 mm, measured in the longitudinal direction of the protection means. The raised portion preferably has a length of 30 to 35 mm, which leaves an essentially flat portion after the raised portion having a longitudinal extent of 15 to 20 mm. Suitably, the total length of the sanitary protection means is about 85 mm. The width of the hygiene protection means, i.e. the lateral extent, is suitably 5-20 mm, preferably 10-15 mm, at the widest part of the spoon-shaped part. The handle-shaped part preferably has a maximum width of 20 mm, the width of the raised part being about 10 mm.
[0017]
One advantage of the protection means according to the invention is that, due to its small size and great flexibility, the protection means can be washed away after use. The used protection means can therefore be disposed of in a simple and convenient manner.
[0018]
The sanitary protection means according to the invention can be used in combination with a panty liner or a sanitary napkin when the flow of bodily fluids is tight or when increased leakage safety is desired, for example for night use.

[0020]
MODES FOR CARRYING OUT THE INVENTION The sanitary protection means 1 shown in FIGS. 1, 2 and 3 is made of a hydrogel, which is intended to face in front of the wearer during use and to the body of the wearer. The cup-shaped part is shaped into the spoon shape shown, with the front cup-shaped part 2 being placed on the wearer's clitoris. The hygiene protection means also has an elongate rear portion 3 which, in use, faces rearward of the wearer and is located above the vaginal opening and extends rearwardly towards the perineum.
[0021]
The hygiene protection means 1 has a lower surface 4 intended to face away from the wearer during use. In this context, the lower surface is preferably liquid-impermeable and can consist of a layer of liquid-impermeable material, such as a plastic film, or a coating of liquid-impermeable material. Alternatively, the sanitary protection means can be manufactured in such a way that an essentially liquid-impermeable surface is formed on the lower surface.
[0022]
The sanitary protection means 1 also has an upper surface 5 intended to face the wearer when using the protection means. The upper surface 5 receives the liquid and receives it in sanitary protection. For this purpose, the upper surface can be covered by an open surface layer of a hydrophilic or hydrophobic material. If the liquid receiving surface consists of a hydrogel surface, a slightly sticky, adherent and damp surface is obtained during absorption, which, on the one hand, is gentle to the wearer's mucous membranes, and, on the other hand, in place when hygiene protection measures are in use It has the advantage of ensuring that it stays tight.
[0023]
When the hygiene protection is wetted during use, the hydrogel absorbs the liquid and swells, whereby the rear part 3 forms a raised part 6 as shown in FIGS. The shape and size of the raised portions 6 have already been determined during the manufacture of the hygiene protection means when the swollen hydrogel is shaped into an anatomically adapted shape. When the hydrogel swells, its surface becomes wet and slightly sticky, which provides a soft and comfortable adhesion of the protective means to the wearer's body, keeping the mucous membrane between the wearer's labia wet. This eliminates the risk of mucous membrane drying and rubbing. The swollen hydrogel is soft, flexible and elastic. That means that when the hygiene protection measures according to the invention are worn, they are not substantially perceived by the wearer. Due to the soft structure of the protection means, the protection means shapes itself according to the wearer's body and avoids discomfort in the form of pressure or the entry of sharp corners. The decompression of the liquid that takes place in the hydrogel during absorption also contributes to the adhesive capacity of the sanitary protection means, as described above, and is therefore advantageous for the retention of the protection means during use.
[0024]
Since the hygiene protection means according to the invention becomes soft, flexible and tacky after wetting, it would be advantageous if provided with a form of gripping member which facilitates removal of the protection means after use. FIG. 4 shows an example of such a gripping member in the form of a gripping loop 7. The gripping loop 7 can be formed from a hydrogel and in this connection can be molded with the sanitary protection means 1 itself. Alternatively, the gripping loop 7 can be a separate component, for example consisting of a lace loop, a plastic band, a metal loop, etc., which is firmly molded, glued or welded on the sanitary protection means.
[0025]
5 and 6 show further examples of gripping members. FIG. 5 shows the hygiene protection means 1, on which two gripping cords 8 are formed. Of course, only one gripping strap 8 can be used and the strap (s) can be secured in another way, for example by welding or gluing. It is also conceivable to fix it by tying the holding string to the sanitary protection means. Such fixation is preferably carried out by providing a sanitary protection means having a through hole (not shown) at the end of the elongated rear part 3 and tying the holding string through the hole.
[0026]
FIG. 6 shows a gripping member in the form of a gripping tab 9. The gripping tab 9 can be one-piece molded with the sanitary protection means 1 in a manner corresponding to that shown in connection with the aforementioned gripping members, or a separate, secured to the sanitary protection means by molding, gluing or welding. Can be made from materials.
[0027]
As far as absorption is concerned, the hygiene protection means 1 shown in FIG. 6 comprises, as far as absorption is concerned, an absorber 10 arranged inside the hydrogel and in that it is made of a material having a higher absorption rate than the surrounding hydrogel. 5 is different from the protection means shown in FIGS. Such an example is preferred when the sanitary protection means 1 is expected to receive a strong body fluid flow and / or a relatively large amount of liquid. Materials that can be used for the inner absorbent body 10 are fibrous materials, absorbent foams, mixtures of fibrous and superabsorbent materials, and the like. The sanitary protection means according to the invention with the internal absorber 10 already has a small raised portion 6 in the elongated rear part 3 of the protection means before absorption. However, when wet, the raised portions 6 swell further and assume the predetermined shape and size shown in FIG.
[0028]
In order for bodily fluids to be rapidly absorbed by the internal absorber 10, the internal absorber is exposed to a flow of bodily fluid through openings 11 in the hydrogel.
[0029]
According to one example (not shown), the raised portion 6 of the sanitary protection means 1 can be provided with a reservoir or cavity in the hydrogel, in which the liquid is temporarily stored before the liquid can be absorbed by the hydrogel. Can be collected. Such an example is similar to that shown in FIG. 6, but without the internal absorber 10.
[0030]
The various gripping members 7, 8, 9 shown are of course interchangeable, so that the type of gripping member can be freely selected, irrespective of the remaining design of the sanitary protection means 1.
