Problems solved by technology

[0004] While compression garments can help protect a healing wound, patients often find them uncomfortable to wear
As a result, patients often do not adhere to postoperative protocols and instead choose to remove clothing, increasing the risk of healing complications

example 1

[0151] Example 1: Calculation of Tensile Test and Pressure

[0152] It is essential that the garment provides proper compression. However, there is no consensus on eg how to define abdominal compression and how it should be calculated. Most human torsos have a somewhat elliptical shape, which implies that the pressure provided eg by the abdominal girdle varies along the torso according to Laplace's equation. A distinction therefore needs to be made between local measurements, eg by probes, and the overall material properties. In the following, guidance is provided on how to measure elastic stress and the associated compression as defined here.

[0153] When an elastic material is stretched or elongated, the material exhibits elastic stress. This elastic stress depends on the elongation and fundamental properties of the elastic material. It can be measured by a standard mechanical tensile test well known in the art.

[0186] Example 2: Materials

[0187] Material A: Padding fabric

[0188] warp knit fabric

[0189] Construction: Double bar raschel knit with a flat back and a pattern of holes (visible) on the front side.

[0190] Yarns: 100% polyester, filament yarns and monofilament pile yarns

[0191] Fabric Properties:

[0192] Thickness: 3.0mm (DIN EN ISO 5084)

[0193] Weight per unit area: 320g / m 2 (ISO3801:1997)

[0194] Compressive stress in transverse direction: 12.0kPa at 40% elongation (DIN 53 577)

[0195] This fabric is essentially an example of a non-stretchable pad fabric.

[0196] Material B: Warp knitted fabric, mesh fabric

[0197] warp knitted fabric

example 3

[0252] Example 3: Elastic properties of Garment 1

[0253] In this example, the support portion is considered to be inextensible in its entirety when calculating the resulting pressure.

[0254] The abdominal belt shown in Figure 3A was used for the tensile test.

[0255] Test samples 1-6, each having a size of approximately 75 mm x 25 mm, were cut from the abdominal belt shown in FIG. 3A. Each 75 mm x 25 mm sample was then cut into three 25 mm x 25 mm pieces as shown in FIG. 3B and tensile tested as in Example 1 .

[0256] Figure 4 shows the mean stress-strain curves from the tensile tests of the test samples labeled 1 and 6 in Figure 3A corresponding to the elongation of the fabric variant C1 in the width direction (fill direction) and length direction (warp direction), respectively. Stress is defined as in Example 1 as the force per unit width of the sample. Figure 4 also shows the mean (width and length) stress-strain curves for fabric variant C1, linearly fitted to the...

Abstract

A post-operative compression garment (10) having a linear elastic section (20) and a supportive section (30) is provided. The supportive section has a controlled stretch-profile with progressive elastic material properties with linear elastic material properties below an extension of 20%. The supportive section may be constructed of a layered material where the two layers have different material properties and where one of the layers is slightly oversized compared to the other layer. The garment can be constructed to fit various parts of the wearer' s body and can be worn immediately after surgery to prevent hernia and / or wound rupture .

Description

technical field [0001] The present invention relates to the field of hernia care and protection, and more particularly to post-operative garments with specific elastic properties for hernia protection. Background technique [0002] A hernia is an abdominal bulge of an abdominal organ or device through the wall of a body cavity. A particular type of hernia is an incisional hernia (abdominal hernia) that occurs when people undergo surgery, in which the incision passes through various tissues, which are thus weakened by the incision. The aforementioned incision may be an incision or hole made in the skin that may be extended through the fascia. It includes midline, transverse, oblique or other incisions made during laparotomy, keyholes made at laparoscopy and trocar sites. Depending on the reason for the surgery (diagnosis), the procedure used, and the patient's general wound healing ability, the chance of developing an incisional hernia ranges from a few percent to more than...
