Description

Technical Field

[0001] This utility model relates to the field of medical care products technology, and more specifically, to a nursing pad with a leak-proof layer and a convenient replacement structure. Background Technology

[0002] Postpartum women, especially those who have given birth vaginally or via cesarean section, experience a lochia discharge period lasting 4-6 weeks. The amount, color, and characteristics of lochia vary at different stages postpartum and are persistent. Therefore, postpartum care pads (also known as maternity pads or postpartum mats) are essential hygiene products for postpartum women while they are resting in bed or active. Currently, common postpartum care pads on the market are mainly composed of a surface layer, a diversion layer, an absorbent core layer, and a bottom layer. However, existing postpartum care pads still have problems such as poor anti-leakage effect, inconvenience in replacement, hygiene hazards, serious waste, and poor economic efficiency.

[0003] Therefore, a nursing pad with a leak-proof layer and an easy-to-replace structure is proposed to address the above problems. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a nursing pad with a leak-proof layer and a convenient replacement structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a nursing pad with a leak-proof layer and a convenient replacement structure, comprising a nursing pad body, tearable dividing lines, and adhesive bodies. The nursing pad body is provided with two tearable dividing lines, and multiple adhesive bodies are fixedly connected to both sides of the nursing pad body. The nursing pad body includes a surface layer, a diversion layer, an absorbent core layer, and a leak-proof bottom layer. The diversion layer is located below the surface layer, the absorbent core layer is located below the diversion layer, and the leak-proof bottom layer is located below the absorbent core layer.

[0006] Preferably, the surface layer is a hydrophilic hot-air nonwoven fabric or a perforated nonwoven fabric.

[0007] Preferably, the flow guiding layer is a mixture of SAP and linseed paper, and the flow guiding layer has a gradient structure.

[0008] Preferably, the distribution density of the superabsorbent resin in the absorbent core layer can decrease from the middle to both sides along the length of the pad body.

[0009] Preferably, the leak-proof bottom layer adopts a composite structure of a hydrophilic non-woven fabric layer and a microporous breathable membrane layer.

[0010] Preferably, the tearable dividing line is a pressed line or a pre-perforated line.

[0011] Preferably, the adhesive body includes an adhesive sticker and a protective film, wherein an adhesive layer is provided on the bottom surface of the adhesive sticker, and a protective film is provided below the adhesive layer on the bottom surface of the adhesive sticker.

[0012] The technical effects and advantages of this utility model are as follows: 1. Compared with existing technologies, this nursing pad with a leak-proof layer and convenient replacement structure uses a composite bottom layer combining a hydrophilic non-woven fabric layer and a microporous breathable membrane layer. This effectively blocks liquid leakage by utilizing the physical size effect of the micropores while ensuring the smooth expulsion of water vapor, solving the problem of traditional PE films being non-breathable. This significantly improves the comfort of postpartum women and reduces the risk of infection. Secondly, it offers a convenient replacement experience: through a "segmented absorbent structure," postpartum women or caregivers can replace only the contaminated section, leaving the dry part intact, much like peeling off a band-aid. This design greatly simplifies the replacement process, avoids secondary contamination of bed sheets caused by traditional replacement methods, and is especially convenient for use while lying on one's side.

[0013] 2. Compared with existing technologies, this nursing pad with a leak-proof layer and convenient replacement structure can be used multiple times and in segments with a single nursing pad, which greatly extends the single use cycle, reduces the consumption of consumables, saves costs for families and society, and conforms to the concept of green environmental protection.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 As attached Figures 1 to 4 The nursing pad shown includes a leak-proof layer and a convenient replacement structure, comprising a nursing pad body 1, tearable dividing lines 2, and adhesive bodies 3. The nursing pad body 1 is provided with two tearable dividing lines 2, and multiple adhesive bodies 3 are fixedly connected to both sides of the nursing pad body 1. The nursing pad body 1 includes a surface layer 11, a diversion layer 12, an absorbent core layer 13, and a leak-proof bottom layer 14. The diversion layer 12 is located below the surface layer 11, the absorbent core layer 13 is located below the diversion layer 12, and the leak-proof bottom layer 14 is located below the absorbent core layer 13.

[0021] Specifically, the device utilizes a composite bottom layer consisting of a hydrophilic non-woven fabric layer 141 and a microporous breathable membrane layer 142. This design effectively blocks liquid leakage by leveraging the physical size effect of the micropores while ensuring the smooth expulsion of water vapor. This solves the problem of traditional PE films being non-breathable, significantly improving the comfort of postpartum women and reducing the risk of infection. Secondly, it offers a convenient changing experience: through a "segmented absorption structure," postpartum women or caregivers can change only the contaminated section, leaving the dry portion intact, much like peeling off a band-aid. This design greatly simplifies the changing process, avoiding secondary contamination of the sheets caused by traditional changing methods, and is especially convenient for use while lying on one's side.

[0022] Example 2 Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details: In a preferred embodiment, the surface layer 11 is a hydrophilic hot-air nonwoven fabric or perforated nonwoven fabric to accelerate liquid penetration and keep the surface dry. The diversion layer 12 is made of a mixture of pulp paper and high-molecular-weight SAP powder to form a loose and porous structure, which can quickly diffuse the liquid penetrating from the surface layer 11 laterally and prevent the liquid from accumulating in a certain local area of ​​the absorbent core layer 13, thereby improving the absorption efficiency. The distribution density of the super absorbent resin in the absorbent core layer 13 can decrease from the middle to both sides along the length of the pad body 1, thereby forming a state that is thick in the middle and thin on both sides, which can better and faster absorb the liquid, while also saving materials.

[0023] In a preferred embodiment, the leak-proof bottom layer 14 adopts a composite structure. The upper layer is a hydrophilic non-woven fabric layer 141, which is bonded to the absorbent core layer 13 and can absorb and disperse any possible minor leaks immediately. The lower layer is a microporous breathable membrane layer 142, with the micropore size controlled at 0.1-0.2 micrometers. This pore size functions as a molecular sieve because the main components of lochia (such as water, salt, and protein) have large molecular clusters that cannot pass through the micropores; while the water vapor molecules produced by the human body are very small and can pass through smoothly, thus achieving breathability without water permeability and solving the problem of stuffiness in traditional PE membranes.

[0024] As a preferred embodiment, the tearable dividing line 2 is formed by a hot pressing process. When a certain area of ​​the nursing pad body 1 is wetted, the user can tear it off along the tearable dividing line 2, while the remaining area can still be used. Thus, a single nursing pad can be used multiple times and in segments, which greatly extends the single use cycle, reduces the consumption of consumables, saves costs for families and society, and conforms to the concept of green environmental protection.

[0025] The working process of this utility model is as follows: First, the protective film 32 can be peeled off from the bottom of the adhesive strip 31, and then the adhesive strip 31 is pasted to the bed sheet to fix the entire nursing pad body 1. Then, when a certain area of ​​the nursing pad body 1 is wetted, the user can peel it off along the tearable dividing line 2, and the remaining area can still be used. By using a nursing pad multiple times and in segments, the single use cycle is greatly extended, the consumption of consumables is reduced, and costs are saved for families and society, which is in line with the concept of green environmental protection. Meanwhile, the upper layer of the leak-proof bottom layer 14 is a hydrophilic non-woven fabric layer 141, which adheres to the absorbent core layer 13, and can absorb and disperse any possible minor leaks immediately. The lower layer is a microporous breathable membrane layer 142, with the micropore size controlled at 0.1-0.2 micrometers. This pore size design cleverly achieves the "molecular sieve" effect: the main component molecules in lochia are large and cannot pass through the micropores; while the water vapor molecules produced by the human body are very small and can pass through smoothly, thus achieving breathability without water permeability. This fundamentally solves the problem of stuffiness in traditional PE films. The above is the working principle of this nursing pad with a leak-proof layer and easy replacement structure.
