Description

本発明は、抗菌性を有する医療用防水敷きシーツに関し、詳しくは銀の超微粉を含有するナイロン糸にて編組した防水敷きシーツにて、被介護者の排泄物の水分などから生ずる各種菌の繁殖に対する抗菌性効果を高めた抗菌性を有する医療用防水敷きシーツに関するものである。   The present invention relates to a waterproof sheet for medical use having antibacterial properties, and in particular, a waterproof sheet that is braided with a nylon thread containing ultrafine silver powder. The present invention relates to a waterproof sheet for medical use having an antibacterial property with enhanced antibacterial effect on breeding.

長寿社会を迎え、寝たきり老人が年々増加して来ている。そして、これら被介護者が就床しているベッドには、腰部に当たる位置にもう一枚の医療用防水敷きシーツが必要とされる場合が多い。   With the longevity society, the number of bedridden elderly people is increasing year by year. In many cases, the bed on which these care recipients are placed requires another sheet of medical waterproofing sheets at a position corresponding to the waist.

しかして、この従来の防水敷きシーツにも、被介護者の発汗、体液、排泄物の水分が敷布団やマットレスに浸透していかないようには工夫が施されている。   Thus, this conventional waterproof sheet is also devised so that the sweater's perspiration, body fluids, and excrement moisture do not penetrate into the mattress and mattress.

即ち、防水敷きシーツの芯にはポリウレタンフィルムが使用され、その上に編地が接着されて構成されている。したがって、ポリウレタンフィルムにて被介護者の排泄物の水分が敷布団、マットレスなどに浸透していくということはなかった。   That is, a polyurethane film is used for the core of the waterproof sheet, and a knitted fabric is adhered thereon. Therefore, the moisture of the caregiver's excrement did not penetrate into the mattress, mattress, etc. with the polyurethane film.

しかしながら、防水敷きシーツ自体に抗菌性、消臭性を発揮するようには配慮されていなかった。したがって、病原菌の繁殖抑制及び消臭効果に大きな問題点があった。
特開平７−３９５６４ However, the waterproof sheet has not been considered to exhibit antibacterial and deodorant properties. Therefore, there are significant problems in the propagation suppression of pathogenic bacteria and the deodorizing effect.
JP-A-7-39564

本発明の防水敷きシーツは、銀の超微粉を含有するナイロン糸にて丸編みした編地を使用することによって上記問題点を解決した。所謂、本発明は銀イオンによる病原菌の繁殖抑制及び消臭効果を持たせた医療用シーツの研究開発に成功した。したがって、従来の問題点を完全に解決できた。   The waterproof laid sheets of the present invention have solved the above problems by using a knitted fabric circularly knitted with nylon yarn containing ultrafine silver powder. In other words, the present invention has succeeded in research and development of a medical sheet that has the effect of inhibiting the propagation of pathogenic bacteria by silver ions and having a deodorizing effect. Therefore, the conventional problems can be solved completely.

本発明は上記課題を解決するためになされたものであって、その要旨とするところは、銀の１ミクロン以下超微粉を混入したナイロンフィラメント使用の７０Ｄ／２４Ｆ〜１４０Ｄ／４８Ｆのナイロン糸を２０〜４０％と通常のポリエステル１００％の７０Ｄ／２４Ｆ〜１４０Ｄ／４８Ｆのポリエステル糸を８０〜６０％使用して２８ゲージ〜３２ゲージに丸編みした編地を０．０５〜０．１５ｍ／ｍ厚のポリウレタンフィルムの両面へ夫々ポリウレタン樹脂を介在して加熱、加圧して積層接着してなる防水敷きシートにて、病原菌の繁殖抑制及び消臭効果を高め、永続させたことを特徴とする抗菌性を有する医療用防水敷きシーツに関するものである。   The present invention has been made to solve the above-mentioned problems. The gist of the present invention is that a nylon yarn of 70D / 24F to 140D / 48F using a nylon filament mixed with ultrafine powder of 1 micron or less of silver is used. 0.05 to 0.15 m / m thickness of knitted fabric circularly knitted to 28 gauge to 32 gauge using 80 to 60% of polyester yarn of 70D / 24F to 140D / 48F of 100% polyester and -40% Anti-bacterial property characterized by improving and perpetuating the growth and deodorizing effect of pathogenic bacteria with waterproofing sheet that is laminated and bonded by heating, pressing and laminating on both sides of polyurethane film The present invention relates to a waterproof sheet for medical use.

本発明の医療用防水敷きシーツは、銀の超微粉を含有するナイロン糸を２０〜４０％と、他には通常のポリエステル糸を８０〜６０％とで丸編みした編地をポリウレタンフィルムの両面に接着剤にて加熱、加圧して積層接着してなる。したがって、抗菌性を強め、消臭効果、耐洗濯性、耐乾燥性を高めた防水敷きシーツで人体から発する汗、体液、排泄物の水分を一時的に保持し、敷布団、敷マットレス等に通しにくい機能を有する。   The waterproof sheet for medical use according to the present invention is formed by knitting a circular knitted fabric of 20 to 40% nylon yarn containing ultrafine silver powder and 80 to 60% normal polyester yarn on both sides of a polyurethane film. The film is laminated and bonded by heating and pressing with an adhesive. Therefore, the waterproof sheets with enhanced antibacterial properties, deodorant effect, washing resistance, and drying resistance temporarily hold the moisture of sweat, body fluids and excrement from the human body, and pass them through mattresses, mattresses, etc. Has difficult functions.

また、各種菌の繁殖に対して抗菌性効果大で、特に病原菌としてはＭＲＳＡ、黄色ブドウ球菌、肺炎桿菌、大腸菌などに対して抗菌効果が顕著である。且又菌の繁殖による異臭の増大を防止する。   In addition, it has a large antibacterial effect on the propagation of various bacteria, and particularly has a remarkable antibacterial effect on MRSA, Staphylococcus aureus, Klebsiella pneumoniae, Escherichia coli and the like as pathogenic bacteria. It also prevents the increase in off-flavors caused by the growth of bacteria.

本発明の医療用防水敷きシーツは、ポリウレタンフィルムの両面に銀１ミクロン以下の超微粉を含有するナイロン糸にて丸編みした編地が接着してあるから、防水敷きシーツの両面を使用でき、甚だ利便性、経済性に富み実用上有益である。   The waterproof sheet for medical use of the present invention has both sides of the polyurethane film bonded with a knitted fabric circularly knitted with nylon yarn containing ultrafine powder of 1 micron or less of silver, so both sides of the waterproof sheet can be used. It is very convenient and economical and useful for practical use.

本発明の抗菌性を有する医療用防水敷きシーツの実施例を別紙図面を参照しながら詳細に説明する。   Embodiments of the waterproof sheet for medical use having antibacterial properties of the present invention will be described in detail with reference to the accompanying drawings.

図４に於て、Ａは銀の超微粉２を含有するナイロン糸１を２０〜４０％と、他の通常のポリエステル糸８０〜６０％とで丸編みしてなる編地である。   In FIG. 4, A is a knitted fabric obtained by circularly knitting nylon yarn 1 containing ultrafine silver powder 2 with 20 to 40% and other ordinary polyester yarns 80 to 60%.

上記編地Ａについて、さらに詳しく述べると、銀１ミクロン以下の超微粉２を混入したナイロンフィラメント使用の、所謂７０Ｄ／２４Ｆ〜１４０Ｄ／４８Ｆのナイロン糸１を２０〜４０％と、通常のポリエステル糸を８０〜６０％を使用して２８ゲージ〜３２ゲージに丸編みしてなる編地である。   The above knitted fabric A will be described in more detail. 20 to 40% of a so-called 70D / 24F to 140D / 48F nylon yarn 1 using a nylon filament mixed with ultrafine powder 2 of 1 micron or less of silver, a normal polyester yarn Is a knitted fabric formed by circular knitting to 28 to 32 gauge using 80 to 60%.

編地Ａを丸編み生地を利用するのは編地にソフト感が出し易く、然も内部の剥がれも周囲への伸びがあるため、ポリウレタンフィルム３からの剥離が起こり難いためである。また、ナイロン糸１を使用した理由は、ナイロン糸１には親水性があるので、水分の吸収により、銀の超微粉２より銀イオンの発生が容易ゆえである。   The reason why the knitted fabric A is made of a circular knitted fabric is that the knitted fabric tends to have a soft feeling, and the internal peeling also extends to the surroundings, so that the polyurethane film 3 hardly peels off. The reason for using the nylon thread 1 is that the nylon thread 1 has hydrophilicity, so that it is easier to generate silver ions than the ultrafine silver powder 2 due to moisture absorption.

さらに、銀の超微粉２入りナイロン糸１を２０〜４０％迄に限定したのは、ナイロン糸１が４０％以上使用すると価格が上がり過ぎるばかりでなく、製品使用者が特異体質の場合、皮膚障害が起こることも考えられるからである。   Furthermore, the nylon thread 1 containing the ultrafine silver powder 2 is limited to 20 to 40% because the nylon thread 1 is used not only when the nylon thread 1 is used at 40% or more, but also when the product user is unusual. This is because a failure may occur.

図４に於て、３は０．５〜０．１５ｍ／ｍ厚のポリウレタンフィルムであって、このポリウレタンフィルム３の両面へ上記編地Ａ、Ｂを夫々馴染みの良い（相性の良い）ポリウレタン系の接着剤４、４を使用して加熱、加圧して積層接着して、本発明の抗菌性を有する医療用防水敷きシーツは構成されるものである。
なお、上記加工を詳しく述べると以下の通りである。
加圧は２．５〜３．０ｋｇ／ｍ２加熱は７５〜８５度Ｃ、時間は０．９ｍ〜１．０ｍ／１分（加圧ローラー、加圧ベルト使用して連続移動。 In FIG. 4, 3 is a polyurethane film having a thickness of 0.5 to 0.15 m / m, and the knitted fabrics A and B are both familiar to the both surfaces of the polyurethane film 3 (good compatibility). Thus, the waterproof sheet for medical use having antibacterial properties of the present invention is constituted by heating and pressing using adhesives 4 and 4 and laminating and bonding.
The above processing will be described in detail as follows.
