Problems solved by technology

[0004] In view of the above-mentioned related technologies, the inventor believes that the antibacterial layer is placed between the water-absorbing layer and the cold compress bag, which has a limited antibacterial effect on the skin of the puerpera above the water-permeable layer, especially in the long-term delivery process, which is not conducive to giving full play to the antibacterial layer. antibacterial effect

Embodiment 1

[0036] Embodiment 1: a kind of perineal pad for obstetrics, such as figure 1 As shown, it includes a water-permeable layer 1, a water-absorbing layer 2 and a water-proof layer 3 arranged in sequence from top to bottom. A micro measuring hand scale 4 is provided. Its preparation method comprises the following steps:

[0037] Preparation of S1 water-permeable layer: take 20kg monoglyceride laurate, add 7.5kg chitosan and 1.8kg acetylated distarch phosphate, then add 36kg water, mix well to make antibacterial slurry; take 10 pieces with a size of 84cm* 54cm non-woven fabric (250 mesh, pore size 58μm), evenly spray 60g / ㎡antibacterial slurry on the surface of the non-woven fabric, and dry at 45°C for 120min to obtain a water-permeable layer.

[0038] S2 Perineal pad assembly: Take 12kg of collagen peptide, add 6kg of angelica polysaccharide and 0.03kg of benzalkonium bromide, mix well, add 48kg of water, stir well, add 78kg of polymer water-absorbent resin, mix well, dry at 80°C ...

Embodiment 2

[0040] The difference between Example 2 and Example 1 is that collagen peptide, angelica polysaccharide and benzalkonium bromide are not added to the polymer water-absorbing resin layer in Example 2, and in Example 2, the polymer water-absorbing resin is directly mixed with the adhesive and extruded A polymer water-absorbing resin layer was made, and the others were consistent with Example 1.

Embodiment 3

[0042] The difference between embodiment 3 and embodiment 1 is that embodiment 3 does not use water to dissolve the antibacterial material, and embodiment 3 directly mixes the polymer water-absorbing resin, antibacterial material and adhesive and then extrudes it to form a polymer water-absorbing resin layer. Example 1 remains the same.

Abstract

The invention discloses a perineal pad for obstetrics and a preparation method thereof, and relates to the technical field of medical materials. A perineal pad for obstetrics, comprising a water-permeable layer, a water-absorbing layer and a water-proof layer arranged sequentially from top to bottom, the edge of the water-permeable layer is fixed on the upper surface of the water-proof layer, and the edge of the bottom surface of the water-proof layer is provided with The micro metering hand says that the water-permeable layer is made of non-woven fabric and oily bacteriostatic material; the oily bacteriostatic material includes the following parts by weight of bacteriostatic raw materials: 10-30 parts of monoglyceride laurate, 5-30 parts of chitosan 10 parts, 1.2‑2.5 parts of acetylated distarch phosphate. The obstetric perineal pad has the advantage of good antibacterial effect. The preparation method comprises the following steps: preparation of a permeable layer, assembly of a perineal pad, and the like. The preparation method has the advantage of improving the antibacterial effect of the product.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a perineal pad for obstetrics and a preparation method thereof. Background technique [0002] The perineal pad is used in the delivery process of obstetric women. On the one hand, the perineal pad helps to prevent blood and other stolen goods from contaminating the bed sheets. On the other hand, it can inhibit bacteria and kill viruses, help prevent infection, and improve the convenience and safety of obstetric surgery. There is more and more research on perineal pads. [0003] CN205359809U discloses a disposable postpartum metering pad, comprising a water-permeable layer, a water-absorbing layer, a cold compress bag and a water-proof layer successively from top to bottom. There is a micro-measurement hand scale, and an antibacterial layer is set between the water-absorbing layer and the cold compress bag; this technical solution helps to measure the amount of postpart...
