図1,2に示すように、本発明の第1の実施形態に係る陰圧治療用装填材1は、透水性弾性体から成る母材3が複数の部分塊5に区分され、個々の部分塊5よりも断面積の小さい連結部7を介して、複数の部分塊5が相互に連なるものである。 As shown in FIGS. 1 and 2, negative pressure therapeutic stuffing 1 according to the first embodiment of the present invention, the base material 3 made of water-permeable elastic member is divided into a plurality of partial masses 5, the individual parts through a small connecting portion 7 cross-sectional area than the mass 5, a plurality of partial masses 5 are those leading to another. 例えばポリウレタンフォーム、ポリエステル系ウレタンフォーム、又はポリエーテル系ウレタンフォームのように、連続気孔を有する発泡樹脂(スポンジ)を透水性弾性体として適用するのが好ましい。 For example, as polyurethane foam, polyester urethane foam or a polyether-based urethane foam, it is preferable to apply a foamed resin having continuous pores (sponge) as a water-permeable elastic member. 上記の断面積の比率は、部分塊5に対して連結部7が1/10〜1/5 0であることが好ましい。 The ratio of the cross sectional area of the above, the connecting portion 7 to the portion ingot 5 is preferably 1 / 10-1 / 5 0. 連結部7の肉厚は1.5〜0.3m mであることが好ましい。 It is preferable the thickness of the connecting portion 7 is 1.5~0.3m m.

図2は、連結部7を表すために隣合う部分塊5の間を空隙としているが、図1に示すように隣合う部分塊5は密接していても良い。 2, although the between portions ingot 5 adjacent to represent the coupling portion 7 and the air gap, partial masses 5 adjacent as shown in FIG. 1 may be closely. 個々の部分塊5は、その厚み方向、幅方向、及び長手方向の一辺の長さをそれぞれ約1〜4cmとした立方体である。 Individual partial mass 5, the thickness direction, a width direction, and the cube longitudinal side length were respectively about 1 to 4 cm. 部分塊5の一辺の長さは4cmを超えても良く1cm未満であっても良い。 Length of one side of the part mass 5 may be better than 1cm be greater than 4 cm. 部分塊5の形状、及び個数が限定されることはなく、個々の部分塊5が、多面体、球体、又は図4(a),(b)に示すような錐体であっても良い。 Shape of the portion lumps 5, and never number is limited, the individual parts lumps 5, polyhedral, spherical, or FIG. 4 (a), the may be a cone, as shown in (b). また、総ての部分塊5のそれぞれの形状、又は寸法が互いに同じである必要はない。 Further, each of the shapes of all parts lumps 5, or size need not be the same to each other.

次に、陰圧治療用装填材1を使用する手順について説明する。 Next, the procedure for using the stuffing 1 for negative pressure therapy. 作業者は総ての連結部7の中から破断するべき対象の連結部を選択する。 Operator selects a connection portion of the object to be broken out of all of the connecting portion 7. 例えば、図3(a)にドットを付した3つの部分塊5を切り分けるには、これらの部分塊5を作業者が把持し、三者が互いに離れるような力を母材3に加える。 For example, the isolate three parts masses 5 marked with dots in FIG. 3 (a), these portions ingot 5 is gripped by the operator, applying a force of three parties away from each other in the base material 3. これにより母材3に発生する応力は、切断する対象となる連結部7に集中し、これらの連結部7が図3(b)に示すように伸長する。 Thus the stress generated in the base material 3 is concentrated on the connecting part 7 for which to cut these connecting portions 7 is extended, as shown in FIG. 3 (b). そして、連結部7が伸長できる限度を超えると直ちに破断するので、この時点で母材3が切り分けられる。 Then, the connecting portion 7 is broken as soon as it exceeds the limit can be extended, the base material 3 is cut at this point. 図4(c)は、母材3から切り離された部分塊5の連結部7の切り口9を表している。 FIG. 4 (c) represents the cut 9 of the connecting part 7 of the part masses 5, separated from the base material 3.

以上に述べた要領で、作業者は、陰圧治療用装填材1を創傷の固有の形状に適合するよう容易に整形することができ、或いは適正な寸法に裁断することができる。 In the manner described above, the operator can cut the stuffing 1 for negative pressure therapy can be easily shaped to conform to the unique shape of the wound, or to an appropriate size. また、作業者は、母材3を切り分けるのに刃物を使用しなくて済むので、医療の現場における手間が大幅に軽減されることになる。 In addition, the operator, since it is not necessary to use a knife to isolate the base material 3, so that the time and effort in the field of medical care is greatly reduced. 上記の応力は、連結部7の破断した直後に残留し、連結部7の切り口9を収縮させる力として作用するので、連結部7が断片化するのを抑止し、透水性弾性体の屑が飛散するのを予防することができる。 Additional stress remains immediately after rupture of the connection portion 7, because they act as a force for contracting the cut 9 of the connecting part 7, to suppress the coupling portion 7 is to fragment, is waste water permeable elastic member it can be prevented from dispersing.

図5(a)は創傷11に倣う形状に整形された陰圧治療用装填材1が装填される工程を表している。 FIG. 5 (a) represents the step of negative pressure therapeutic loading member 1 is shaped into a shape to follow the wound 11 is loaded. 図5(b)は被覆シート13の内側に装填された陰圧治療用装填材1が大気圧で圧縮され創傷11に密接した例を示している。 FIG. 5 (b) shows an example in which close contact with the wound 11 negative pressure therapeutic stuffing 1 loaded inside is compressed by the atmospheric pressure of the cover sheet 13. 被覆シート13の内側に陰圧を導くホースは同図で省略されている。 Hose for guiding a negative pressure to the inside of the cover sheet 13 is omitted in FIG. 上記のように切断された連結部以外の連結部7によって図5(a)に示した陰圧治療用装填材1の母材3の連結が保たれる。 Connecting the base material 3 of FIGS. 5 (a) negative pressure therapeutic stuffing 1 shown by a connecting portion 7 except the linking portion that is cut as described above is maintained. このため、創傷11に装着される前に陰圧治療用装填材1が不用意に分散するようなことはなく、或いは個々の部分塊5が母材3から脱落しないという利点がある。 Therefore, never as negative pressure therapy stuffing 1 is inadvertently dispersed before being attached to the wound 11, or individual parts ingot 5 is advantageous in that not fall from the base material 3.

更に、複数の部分塊5の配列されている方向は、図1に示すように母材3の厚み方向、幅方向、及び長手方向の三方向に一致するので、創傷11の深さ、表面積の広さ、又は形状に合うように、作業者は母材3の三方向の寸法をそれぞれ自在に調整することができる。 Further, the direction being arranged in a plurality of portions lumps 5, the thickness direction of the base material 3 as shown in FIG. 1, the width direction, and therefore coincides with the longitudinal direction of the three directions, the wound 11 depth, surface area size, or to fit the shape, the operator can freely adjust each three dimensions of the base material 3. 例えば、創傷11が比較的浅いときは、母材3の厚み方向に並ぶ部分塊5の個数が少なくなるように母材3から幾つかの部分塊5を切り離し、創傷11が深いほど母材3の厚み方向に並ぶ部分塊5を母材3から切り離す個数を少なくすれば良い。 For example, when the wound 11 is relatively shallow, disconnect the several parts mass 5 from the base metal 3 as the number of partial mass 5 to align in the thickness direction of the base material 3 decreases, the wound 11 is deeper preform 3 the partial mass 5 arranged in the thickness direction may be reduced the number of disconnecting from the base material 3.

図6(a)に示すように、本発明の第2の実施形態に係る陰圧治療用装填材15は、棒状の母材3に複数の切欠17が形成され、複数の部分塊5が互いに切欠17を境に隣接するものである。 As shown in FIG. 6 (a), negative pressure therapeutic stuffing 15 according to the second embodiment of the present invention is formed with a plurality of notches 17 in the base material 3 of the rod-like, mutually plurality of partial masses 5 it is intended to adjacent the notch 17 as a boundary. 複数の切欠17は、母材3の長手方向に等間隔で並び、これらが母材3に切り込む向きは、母材3の長手方向に切欠17の並ぶ順で交互に反対向きである。 A plurality of notches 17 are aligned at equal intervals in the longitudinal direction of the base material 3, the direction in which they cut into the base material 3 is opposite alternately in the order arranged in the longitudinal direction of the base material 3 of the notch 17.

陰圧治療用装填材15を整形、又は裁断する作業者は、切欠17を目印にして母材3を切り分けるべき箇所を認識できるので、母材3を切り分けた後のその仕上がりを容易に予測することができる。 Shaping the negative pressure therapeutic stuffing 15, or cut to the operator, can recognize the portion to isolate the base metal 3 in the mark notches 17 readily predict the finish after carved preform 3 be able to. 符号10は連結部7の切り口を指している。 Reference numeral 10 points to cut the connecting portion 7. 図6(b)に示すように、陰圧治療用装填材15を湾曲させた形態で被覆シートの内側に装填することができる。 As shown in FIG. 6 (b), it can be loaded to the inside of the cover sheet in the form obtained by bending a negative pressure therapeutic stuffing 15. このとき、複数の切欠17のうち母材3の湾曲する内側の切欠17が閉じ、母材3の湾曲する外側の切欠17が開くように、陰圧治療用装填材15が変形するので、陰圧治療用装填材15の母材3に不要な力を加えることなく、陰圧治療用装填材15を滑らかな円弧状に湾曲させることができる。 In this case, closing the inner notch 17 curving of the base material 3 out of the plurality of notches 17, so as to open the outer notch 17 of curvature of the base material 3, since negative pressure therapeutic stuffing 15 is deformed, Yin without the base material 3 of the pressure therapeutic stuffing 15 adding unnecessary force, it can be curved negative pressure therapeutic stuffing 15 in a smooth arc shape.

複数の切欠17の個数、又はそれらの間隔は何ら限定されるものではなく、総ての切欠17が母材3に切り込む向きを一方に揃えてもよい。 The number of the plurality of notches 17, or their spacing is not intended to be limiting in any way, all of the cut 17 may be aligned in one orientation to cut the base material 3. この他の陰圧治療用装填材15の構成、及び陰圧治療用装填材15による効果は陰圧治療用装填材1と同様である。 The configuration of the other negative pressure therapeutic stuffing 15, and the effect of negative pressure therapeutic stuffing 15 is similar to a loading member 1 for negative pressure therapy.
