Embodiment 1

[0024] Embodiment 1: The initial modulus and residual deformation test method of the material of the present invention.

[0025] refer to Figure 4 , make the cylinder into a circle, place it between the upper and lower chucks of the electronic tension machine, and adjust the position of the upper chuck of the tension machine so that it just touches the cylinder. Set the running direction of the tensile machine downward, that is, the force displayed on the tensile machine is pressure (N). The pressure should fluctuate around 0 when the collet is just in contact with the cylinder.

[0026] Measure the outer diameter D of the cylinder with a steel ruler. Set the downward displacement limit of the tensile machine as D x 20%. Start the tensile machine (the speed of the upper chuck is 10 mm / min), the upper chuck of the tensile machine moves down by 20% of the outer diameter of the cylinder, and the record shows that the force (N) is the initial modulus of the material. Then kee...

Embodiment 2

[0027] Example 2: Conical Wound Dressing of the Invention

[0028] refer to figure 1 The elliptical cone shown in the cone dressing was formed by direct foaming of polyurethane in a pre-prepared mold. The bottom diameter of the cylinder is 44mm, the cone angle is 15 degrees, and the total height of the cone-shaped dressing is 45mm.

[0029] The initial modulus of the material tested by the method of Example 1 was 12N. The residual deformation is 0.9mm.

[0030] The outer covering layer of the dressing is made of 100% alginate fiber non-woven fabric, the weight of the non-woven fabric is 120 grams per square meter (thickness is about 0.9 mm), and the hygroscopicity is 17 grams per 100 square centimeters. Laminated to polyurethane cone with medical adhesive.

Embodiment 3

[0031] Example 3: Conical Wound Dressing of the Invention

[0032] refer to figure 2 The cone-shaped dressing is formed into a supporting fixed component according to the method. The cotton pad is made of 100% cotton non-woven fabric, the weight is 100 grams per square meter, the shape is round, and the diameter is 50mm; the application adopts a rectangular transparent application of 120×100mm .

Abstract

The invention relates to a cone-shaped wound dressing for postoperative care of anorectal surgery. The cone-shaped wound dressing at least includes a cone with a bottom outer diameter of 10-120 mm, a height of 10-150 mm, and a cone angle of 0-75 degrees. The cone is covered with a layer of hygroscopic material. The cone-shaped wound dressing of the present invention is ingeniously designed. It is designed as a cone-shaped wound dressing that matches the wound in shape and is covered with absorbent material on the surface. It can be used for wound care after human anorectal surgery. Easy to change dressing, convenient and simple to operate. Moreover, the cone-shaped dressing can use hygroscopic medical materials, which is more conducive to wound healing. It can effectively reduce the difficulty of nursing, reduce the intensity of nursing, avoid cross-infection caused by leakage, and shorten the postoperative nursing time of anorectal surgery.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a tapered wound dressing for nursing after anorectal surgery. Background technique [0002] It is difficult to care for wounds after anorectal surgery, mainly because the anus has a special shape and cannot be treated with conventional flat or strip dressings. Clinically, in order to properly handle such wounds and provide a relatively ideal healing environment for wound healing, medical staff have to cut the gauze / dressing into pieces, then fill the wound on the anus, and finally find a suitable one. On top of the cotton pad, apply several strips of medical tape to the cotton pad to hold the dressing in place. These steps are cumbersome and time-consuming, which is not conducive to wound care, wastes a lot of time for nurses, and increases the intensity of care. And sometimes due to poor sealing of the tamponade, easy leakage of fluid leads to cross-infection and t...
