Description
本発明は、手術、口腔、歯科等の用いる医療用糸付きガーゼに関する。 The present invention relates to a gauze with a medical thread for use in surgery, oral cavity, dentistry and the like.
外科手術では、出血した血液を吸収させるためガーゼが使用されるが、血液を吸収したガーゼが見分けにくいため、術後、体内に残されてしまう場合がある。例えば、特許文献１、特許文献２、特許文献３では術後、体内に残されるのを防ぐためのＸ線造影繊維を含む医療用ガーゼが開発されている。又、特許文献４では鏡視下手術を施行際の挿入しやすいガーゼが記述されている。
歯科や口腔内の出血や唾液、体液等の除去にもガーゼ、脱脂綿等が用いられているが、幼児、小児、高齢者の患者では誤飲して、喉に詰まらせたりする危険がある。このような医療用の問題を解決する安全で挿入も容易で、取り除くのも容易なガーゼはない。 Gauze, absorbent cotton, etc. are also used to remove bleeding, saliva, body fluid, etc. in dentistry and oral cavity, but infants, children, and elderly patients may accidentally swallow and clog their throats. There is no gauze that is safe, easy to insert, and easy to remove, solving these medical problems.
手術、口腔、歯科の止血や貯留液の除去に安全で挿入し易く、吸水性に優れ、且つ取り除き易いガーゼ。 Gauze that is safe and easy to insert for surgery, oral cavity, dental hemostasis and removal of stored fluid, has excellent water absorption and is easy to remove.
以上の課題を解決するために開発した医療用糸付きガーゼは、
１．ロール状のガーゼ中央を糸で縫って固定しその糸の両端が伸びていることを特徴とする医療用糸付きガーゼである。
２．高分子吸水材を含むロール状のガーゼ中央を糸で縫って固定しその糸の両端が伸びていることを特徴とする医療用糸付きガーゼである。
３．１０乃至２００ｍｍ×５０乃至６００ｍｍのガーゼを円形若しくは楕円形のロール状に巻き、ガーゼ中央を糸で縫って固定しその糸の両端が１０ｃｍ乃至１００ｃｍ伸びていることを特徴とする医療用糸付きガーゼである。
４．高分子吸水材を含む１０乃至２００ｍｍ×５０乃至６００ｍｍのガーゼを円形若しくは楕円形のロール状に巻き、ガーゼ中央を糸で縫って固定しその糸の両端が１０ｃｍ乃至１００ｃｍ伸びていることを特徴とする医療用糸付きガーゼである。
５．シート若しくは繊維状の高分子吸水材を含む１０乃至２００ｍｍ×５０乃至６００ｍｍのガーゼを円形若しくは楕円形のロール状に巻き、ガーゼ中央を糸で縫って固定しその糸の両端が１０ｃｍ乃至１００ｃｍ伸びていることを特徴する医療用糸付きガーゼである。

試験例１．吸水量試験
ＪＩＳ Ｌ１９１２ 6.12.3の吸水量試験方法に準じて実施例１〜３の用いたガーゼと市販品（白十字社製、ロール綿）と比較し、評価した。
方法：試験片（１００×１００ｍｍ）試験片を5個採取し、1個の試験片の重さが１ｇ未満の場合には1gになるまで試験片を重ねる。この試験片を０．０１ｇの精度を持つカバー付きこの試験片の重量を測定した。この試験片をステンレス金網の縁にクリップで止め、室温の水槽に水面下２０ｍｍに斜めに入れて気泡の出ないようにする。1分後に試験片と金網を取り出し、一端のクリップを残して他のクリップを外し、垂直に２分つるし、水分を切った後金網から試験片を外し、秤量ガラスにいれて重さをはかる。これを５回繰りかえし、平均値を算出した。実施例１で用いた試験片（３０×１５０ｍｍ）では２．４５ｇ、実施例２の試験片（３０×２５０ｍｍ）では４．０９ｇ、実施例３の試験片（３０×３００ｍｍ）では４．９１ｇの吸水量であった。ｇ当たりの吸水量はそれぞれ１１．１４ｇ、１１．０５ｇ、１１．４１ｇであり、ｇ当たりの吸水量は、市販品（白十字社製、ロール綿）の３．３６ｇに比べ優れていた。
Test Example 1 Water absorption test In accordance with the water absorption test method of JIS L1912 6.12.3, the gauze used in Examples 1 to 3 was compared with a commercial product (white cotton, roll cotton) and evaluated.
Method: Five test pieces (100 × 100 mm) are collected, and if one test piece weighs less than 1 g, the test pieces are stacked until 1 g is reached. The weight of this test piece with a cover having an accuracy of 0.01 g was measured. The test piece is clipped to the edge of the stainless steel wire mesh and placed in a room temperature water tank at an angle of 20 mm below the surface of the water so as not to generate bubbles. After 1 minute, take out the test piece and the wire mesh, remove the other clip except for one end of the clip, hang it vertically for 2 minutes, remove moisture, remove the test piece from the wire mesh, put in a weighing glass and weigh. This was repeated 5 times, and the average value was calculated. 2.45 g for the test piece (30 × 150 mm) used in Example 1, 4.09 g for the test piece of Example 2 (30 × 250 mm), and 4.91 g for the test piece of Example 3 (30 × 300 mm). It was the amount of water absorption. The water absorption per g was 11.14 g, 11.05 g, and 11.41 g, respectively, and the water absorption per g was superior to 3.36 g of a commercially available product (white cotton, roll cotton).
試験例２．溶出試験
実施例１０および実施例１１の糸付きガーゼを生理食塩水に浸し、24時間後の溶出を調べたが、高分子吸水材の溶出は認められなかった。
Test Example 2 Dissolution test The gauze with thread of Example 10 and Example 11 was immersed in physiological saline, and the dissolution after 24 hours was examined. The dissolution of the polymer water-absorbing material was not observed.
