Description
本発明は、手術室用フロアマットに関するものである。 The present invention relates to a floor mat for an operating room.
手術室用フロアマットは、手術室にて医師が手術をする際、手術台との高さ調整及び足下の保温等の用途に使用されている。 An operating room floor mat is used for purposes such as height adjustment with an operating table and heat insulation of a foot when a doctor performs an operation in an operating room.
現状のフロアマットは、塩化ビニルシートよりなっている。 The current floor mat is made of a vinyl chloride sheet.
フロアマットにクッション材を使用する方法（特開２００４−２６１５６５号公報、特開２００５−１６８６３７号公報）が知られているが、手術室用のフロアマットは知られていない。
塩化ビニルシートよりなるフロアマットは重量があり、弾力性にも劣るため、手術室への持ち運びや手術時の足もとの感触が悪かった。 The floor mat made of a vinyl chloride sheet is heavy and inferior in elasticity, so it is not easy to carry to the operating room or feel the foot during surgery.
ポリエチレン系発泡体のみのマットでは、弾力性があり軽量であるが、使用中にマットが滑って移動してしまうことがある。 A mat made of only a polyethylene foam is elastic and lightweight, but the mat may slip and move during use.
本発明の手術室用フロアマットは、塩化ビニルシートの上に上段が下段より小さい２段より成るポリエチレン系発泡体を貼り合わせてなるものである。
本発明において、ポリエチレン系発泡体の発泡倍率は６〜４０倍が好ましい。
The floor mat for an operating room according to the present invention is formed by bonding a polyethylene-based foam composed of two tiers whose upper stage is smaller than the lower stage on a vinyl chloride sheet.
In the present invention, the expansion ratio of the polyethylene foam is preferably 6 to 40 times.
塩化ビニルシートとポリエチレン系発泡体を積層する方法は、接着、融着等の公知の方法が用いられる。
ポリエチレン系発泡体の上段と下段の加工は、ルーター加工が好ましい。
As a method of laminating the vinyl chloride sheet and the polyethylene foam, a known method such as adhesion or fusion is used.
Router processing is preferable for processing the upper and lower stages of the polyethylene foam.
本発明に係るポリエチレン系発泡体は、ポリエチレン系樹脂１００重量部に有機過酸化物、発泡剤、発泡助剤、充填剤を添加混練して加熱発泡させてなる独立気泡体である。ポリエチレン系樹脂としては、例えば低密度ポリエチレン、中密度ポリエチレン、高密度ポリエチレン、エチレン酢酸ビニル共重合体、メタロセン触媒を使用して重合したポリエチレン系樹脂、塩素化ポリエチレン等が使用できる。 The polyethylene foam according to the present invention is a closed cell body obtained by adding and kneading an organic peroxide, a foaming agent, a foaming aid, and a filler to 100 parts by weight of a polyethylene resin, followed by heating and foaming. Examples of the polyethylene resin include low density polyethylene, medium density polyethylene, high density polyethylene, ethylene vinyl acetate copolymer, polyethylene resin polymerized using a metallocene catalyst, and chlorinated polyethylene.
本発明において、ポリエチレン系発泡体の発泡倍率は、６〜４０倍が好ましく、２０〜４０倍が特に好ましい。６倍未満の場合は、クッション性が不足するとともに重量が重くなってしまう。４０倍を超える場合は、硬さが不足して使用を重ねることにより厚みが減少してしまう。
塩化ビニルシートのＣタイプ硬度は７０〜８５が好ましい。７０未満の場合は、足元が不安定になり、８５を超えるとクッション性が不足する。
In the present invention, the expansion ratio of the polyethylene foam is preferably 6 to 40 times, and particularly preferably 20 to 40 times. If it is less than 6 times, the cushioning properties are insufficient and the weight is increased. When it exceeds 40 times, the hardness is insufficient and the thickness is reduced by repeated use.
The C type hardness of the vinyl chloride sheet is preferably 70 to 85. If it is less than 70, the foot becomes unstable, and if it exceeds 85, cushioning properties are insufficient.
本発明の方法によれば、軽量で弾力性、断熱性に優れた手術室用のフロアマットを得ることが出来、適度の弾力性は使用者の疲労軽減になる。 According to the method of the present invention, it is possible to obtain a floor mat for an operating room that is lightweight and has excellent elasticity and heat insulation, and moderate elasticity can reduce user fatigue.
以下本発明の実施形態を図面に基づき説明する。図１，図２は本発明の手術室用のフロアマットの全体構成を示す斜視図と断面図である。
塩化ビニルシート２は、Ｃタイプ硬度７８、ポリエチレン系発泡体１は、低密度発泡体を発泡させたもので、発泡倍率３０倍（三和化工株式会社製、商品名：サンペルカＬ−２５００）であり、上段１（ａ）の高さは１０ｍｍ、下段１（ｂ）の高さは１２ｍｍである。
Embodiments of the present invention will be described below with reference to the drawings. 1 and 2 are a perspective view and a cross-sectional view showing the overall configuration of a floor mat for an operating room according to the present invention.
The vinyl chloride sheet 2 has a C-type hardness of 78, and the polyethylene-based foam 1 is obtained by foaming a low-density foam. The foaming ratio is 30 times (manufactured by Sanwa Chemical Co., Ltd., trade name: Sanperuka L-2500). Yes, the height of the upper stage 1 (a) is 10 mm, and the height of the lower stage 1 (b) is 12 mm.
本願発明のフロアマットは、塩化ビニルシート２の上面にポリエチレン系発泡体１を積層したものである。 The floor mat of the present invention is obtained by laminating a polyethylene foam 1 on the upper surface of a vinyl chloride sheet 2.
塩化ビニルシートを下面にすることにより、手術中に医者が動いてもフロアマットは移動することがなく、安定して手術ができる。 By placing the vinyl chloride sheet on the lower surface, the floor mat does not move even if the doctor moves during the operation, and the operation can be performed stably.
ポリエチレン系発泡体を上面にすることにより、断熱性があるため冬でも足もとが冷えることが無く、また弾力性があるため疲れにくい。 By using a polyethylene-based foam on the top surface, there is heat insulation, so your feet won't get cold even in winter, and because it is elastic, it won't get tired easily.
塩化ビニルシートの厚みは２〜５ｍｍが好ましい。２ｍｍ未満の場合は滑り止めの効果がなくなり、５ｍｍを超えると重量が重くなり移動等が困難になる。 The thickness of the vinyl chloride sheet is preferably 2 to 5 mm. If it is less than 2 mm, the effect of preventing slipping is lost, and if it exceeds 5 mm, the weight increases and movement or the like becomes difficult.
ポリエチレン系発泡体の厚みは２０〜５０ｍｍが好ましく、２０ｍｍ未満の場合は弾力性、断熱性が劣り、５０ｍｍを超えると足もとが不安定になり手術に支障をきたす。 The thickness of the polyethylene-based foam is preferably 20 to 50 mm. If the thickness is less than 20 mm, the elasticity and heat insulating properties are inferior, and if it exceeds 50 mm, the foot becomes unstable and hinders surgery.
本願発明のフロアマットの形状は、長方形のものに限らず正方形、円形、その他多角形であってもよい。
ポリエチレン系発泡体は２段より成り、各段の高さは１０〜１５ｍｍが好ましく、１５ｍｍを超えるとつまずき易くなる。
The shape of the floor mat of the present invention is not limited to a rectangular shape, and may be a square, a circle, or other polygons.
The polyethylene-based foam is composed of two steps, and the height of each step is preferably 10 to 15 mm.
以上のように、本発明の方法によれば、塩化ビニルシートとポリエチレン系発泡体を積層したフロアマットを得ることが出来る。本発明の方法によって製造されたフロアマットは、軽量で弾力性、断熱性に優れ、手術室用のフロアマットの用途に適用できる。 As described above, according to the method of the present invention, a floor mat in which a vinyl chloride sheet and a polyethylene foam are laminated can be obtained. The floor mat produced by the method of the present invention is lightweight, excellent in elasticity and heat insulation, and can be applied to the use of a floor mat for an operating room.
