Description

  The present invention relates to a medical cloth material that directly touches the human body, such as a waist fixing band, and more specifically, relates to a medical cloth material that has good adhesion to the body and good air permeability.

  One medical device for preventing or treating lumbar disease is a lumbar fixation band. For example, as shown in Patent Document 1, the lumbar fixation band has a function of reducing back pain by increasing abdominal pressure by reducing a load on the lumbar spine by winding a belt-shaped belt along the waist.

  Normally, this type of lumbar fixation band is designed to fix the trunk by combining a stretchable cloth material and a non-stretchable cloth material. Since it touches directly over, it is preferable that it is comprised with the skin-friendly material (medical cloth material).

  However, the conventional medical cloth materials have the following problems. That is, the conventional medical cloth material has been subjected to uneven treatment on the surface in order to reduce the contact area in order to reduce the burden on the skin and to ensure air permeability.

  However, when the uneven treatment is applied, the contact area with the skin is reduced, so there are problems such as standing up with the lumbar fixation band attached, and the lumbar fixation band moving when the beater rolls over. It was.

  In view of this, medical cloth materials that have a non-slip effect by applying or impregnating a non-slip material such as rubber or silicon on the surface of the medical cloth material have been studied. Inhibiting may cause stuffiness or rash.

JP 2003-144469 A

  Therefore, in order to solve the above-described problems, the present invention is to provide a medical cloth material having good adhesion to the skin and good air permeability, and a waist fixing band using the medical cloth material.

  In order to achieve the above-described object, the present invention has several features described below. The invention according to claim 1 is a medical cloth material in which a hollow layer is formed between a base cloth and a front cloth, and at least a surface of the front cloth has a coating layer as a non-slip means of 0. It is characterized by being provided with a thickness of 5 to 1.0 μm.

  The invention described in claim 2 is characterized in that, in the above-mentioned claim 1, irregularities exposed by a stitch or a weave are formed, and the coating layer is provided on the outermost surface of the front cloth. .

  Invention of Claim 3 is the said Claim 1 or 2 WHEREIN: The said coating layer is 20-30 wt% of styrene resin, 20-30 wt% of olefin resin, and 40-50 wt% of refined mineral oil by predetermined | prescribed compounding ratio. It is characterized by comprising a coating material that is blended.

  The present invention also includes a lumbar fixing band using the medical cloth material according to any one of claims 1 to 3.

  According to the first aspect of the present invention, the coating layer is formed on the surface of the surface cloth with a thickness of 0.5 to 1.0 μm, so that the air tightness is secured and the adhesion to the skin is ensured. It is good and will not slip even if it moves or rolls over.

  That is, when the layer thickness of the coating layer is less than 0.5 μm, the coating layer becomes too thin and the thickness may be uneven. On the other hand, if the coating layer thickness is larger than 1.0 μm, the coating material may be clogged with the fabric, which may impair air permeability.

  According to invention of Claim 2, when the unevenness | corrugation exposed by the stitch or the weave is formed in the surface of the surface cloth, since the coating layer is formed only in the convex part, Since there is no coating layer, air permeability can be reliably ensured.

  According to the invention described in claim 3, the coating layer is made of a coating material obtained by blending styrene resin 20 to 30 wt%, olefin resin 20 to 30 wt%, and refined mineral oil 40 to 50 wt% in a predetermined blending ratio. As a result, it has good affinity for the skin and can effectively prevent stuffiness and rash.

  According to the invention described in claim 4, by using this medical cloth material to produce a waist fixing band, even if it moves or lies down, it does not come into close contact with the skin and is used for a long time. A lumbar fixation band that does not get muggy or rash is obtained.

  Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a waist fixing band using a medical cloth material according to an embodiment of the present invention, and FIG. 2 is a schematic view of the medical cloth material of the present invention.

  As shown in FIG. 1, the waist fixing band 1 is composed of a belt-like body that is wound around the waist of a human body. The waist belt 2 mainly fixes the waist and the pelvic belt 3 mainly fixes the pelvis. And. In addition, in this invention, since the specific shape and structure of the waist fixing band 1 are arbitrary matters, the description is abbreviate | omitted.

  A dedicated medical cloth material 4 is used for the waist belt 2 of the waist fixing band 1 of the present invention. As shown in FIG. 2, the medical cloth material 4 is made of a so-called double raschel fabric in which a predetermined hollow layer 43 is formed between a base material 41 serving as a base and a surface cloth 42 that contacts the skin. .

In this example, the medical cloth material 4 has a basis weight of 185 g / m ² , a polyester yarn having a base material 41 of 84 dtex 36 filaments, a front cloth 42 of 84 dtex 36 filaments, and a hollow layer of 22 dtex 1 filament. Is formed to be about 1.4 mm.

  In this example, a double russell fabric (product name: 4WR621) manufactured by Hokuriku Estale is used as the medical fabric material 4, but other fabric materials may be used. On the surface of the surface cloth 42, irregularities having a honeycomb-like stitch pattern are formed.

  A coating layer 5 as anti-slip means is formed on the surface (surface of the skin) of the front cloth 42. Referring also to FIG. 3, the coating layer 5 is preferably formed on the surface of the outer fabric 42 so that the thickness T is 0.5 to 1.0 μm.

  More preferably, the surface cloth 42 has irregularities that are exposed by stitches or textures, but the coating layer 5 is formed only on the convex portions of the surface cloth 42. In this example, it is formed only on the surface of the convex portion among the irregularities formed by the honeycomb-like stitches.

  According to this, since the coating layer 5 is formed extremely thin on the convex portion on the outermost surface of the outer cloth 42, the adhesion to the human body can be improved without impairing the basic performance of the medical cloth material 4. As a result, the displacement of the waist fixing band 1 can be effectively prevented.

  That is, when the layer thickness of the coating layer is less than 0.5 μm, the coating layer becomes too thin and the thickness may be uneven. On the other hand, if the coating layer thickness is larger than 1.0 μm, the coating material may be clogged with the fabric, which may impair air permeability.

  The coating layer 5 is made of a coating material obtained by blending 20 to 30 wt% of a styrene resin, 20 to 30 wt% of an olefin resin, and 40 to 50 wt% of a refined mineral oil at a predetermined blending ratio.

  In this example, the coating material is, for example, Sanyo Kasei Co., Ltd. made by Wytemelt, but if the coating layer 5 is a material that can be uniformly formed on the surface of the surface cloth 42 within the above conditions, Other than that.

  In this example, the coating layer 5 is applied to the front surface of the front cloth 42. However, other than this, for example, the coating layer 5 may be formed in a line shape, a dot shape, or a wave shape. It can be changed arbitrarily.

  FIG. 4 is a schematic view showing an example of a coating apparatus 6 for forming the coating layer 4 of the present invention. As shown in FIG. 4, the coating apparatus 6 includes a conveyance path for feeding the raw fabric cloth 71 fed from the mother 7 toward the apparatus body and winding the completed medical cloth material 4 in a roll shape. Yes.

  On the conveyance path, guide rollers 61 and 61 (62, 62) for guiding the raw fabric 71 are provided in two places in a pair of left and right, for a total of four places. A transfer roller 63 for transferring the coating material onto the surface of the original fabric cloth 71 and a receiving roller 64 disposed opposite to the transfer roller 63 with the original fabric cloth 71 interposed therebetween are provided at the center of the conveyance path.

  An application unit 65 for applying a coating material toward the transfer roller 63 is provided on the upstream side (right side surface) of the transfer roller 63 in the rotation direction (counterclockwise in this example). In this example, the coating unit 65 is configured to apply the coating material melted at a predetermined temperature toward the transfer roller 63, but may have a configuration other than this.

  Either one or both of the transfer roller 63 and the receiving roller 64 is provided with a pressing means (not shown) that presses the original fabric 71 with a predetermined pressure. The coating material is applied in a pressed state at 3 to 0.8 MPa (more preferably 0.4 to 0.6 MPa).

  According to this, when the press pressure is less than 0.3 MPa, the coating material may not be uniformly applied to the raw fabric 71 and uneven application may occur. On the other hand, if the press pressure is greater than 0.8 MPa, the coating material may enter the inside of the raw fabric 71 too much and impair air permeability.

A removal unit 66 for removing the coating material remaining on the transfer roller 63 after passing through the original fabric 71 is provided on the downstream side in the rotation direction of the transfer roller 63 (left side in FIG. 4). In this example, the removal unit 66 scrapes the coating material remaining on the transfer roller 63 by bringing the tip of the removal head into contact with the surface of the transfer roller 63.
The removal unit 66 may use other removal means.

Next, the dynamic friction coefficient test based on JIS-K-7175 was performed on the medical cloth material 4 having the coating layer 5 created using the above coating apparatus. The measurement conditions are as follows:
[Measurement test]: JIS-K-7175
[Tensile speed]: 10 cm / min
[Friction element]: Area 25 m ²
[Friction cloth]: Cotton cloth (Kanakin)

The dynamic friction coefficient measured by the above measuring method is shown below.
[Average tension / mass during movement]: 125 gf
[With coating layer]: Dynamic friction coefficient 2.5
[No coating layer]: Coefficient of dynamic friction 0.5

  From the above results, the medical cloth material of the present invention has a dynamic coefficient of friction that is about five times greater when the coating layer is provided than when the coating layer is not provided. Further, the air permeability is substantially constant regardless of the presence or absence of the coating layer.

  In this example, the medical cloth material is exemplified for a case where a double raschel cloth having an intermediate layer is used. However, if the cloth used as the base is a material capable of forming the coating layer 5, natural fibers, chemical fibers, etc. It can be arbitrarily changed according to specifications such as woven fabric and non-woven fabric.

  In this embodiment, the case where the medical cloth material is applied to the waist fixing band is illustrated, but the medical cloth material of the present invention may be used for various corsets and supporters. Furthermore, it can also be used for slip prevention such as gloves and socks.
