Description

Light incontinence pad with flexible side leakage prevention barrier TECHNICAL FIELD

[0001] The utility model relates to sanitary product technical field, concretely relates to a light incontinence pad with flexible side leakage prevention barrier. BACKGROUND

[0002] Light incontinence generally refers to mild urinary incontinence, which means that urine will involuntarily flow out of the patient under certain specific conditions, such as coughing, sneezing or light exercise. Light incontinence pads or light incontinence pads and other incontinence care products can be used to assist the discharge of urine in daily life for patients with mild incontinence, improving their quality of life. Incontinence care products usually need to have the functions of absorption capacity, comfort, side leakage prevention, etc. Incontinence care products can achieve good absorption capacity by referring to the absorption core of sanitary napkins, paper diapers and other products. Incontinence care products need to set up a barrier structure that can block or absorb liquid to achieve the function of side leakage prevention. The barrier structure of some incontinence care products currently squeezes the position of the thigh root of the human body, although it can achieve good side leakage prevention effect, but it reduces the comfort of incontinence care products.

[0003] A disposable light incontinence pad is disclosed in Chinese Patent No. CN219070982U, which comprises a non-woven fabric bottom film, a top of the non-woven fabric bottom film is fixedly provided with an adhesive cloth, both ends of the top of the adhesive cloth are fixedly provided with adhesive tapes, the top of the non-woven fabric bottom film is fixedly provided with a shaping pad layer, the top of the shaping pad layer is fixedly provided with a positioning water absorption layer, the top of the positioning water absorption layer is fixedly provided with a flow guide layer, the top of the flow guide layer is fixedly provided with a skin layer, the top of the skin layer is fixedly provided with absorbing cotton in the middle, the top of the skin layer is integrally provided with a flange on the side, an oil paper layer is arranged outside the flange, an inner absorbing strip is fixedly arranged inside the flange, and the two sides of the absorbing cotton are connected with the inner absorbing strip. The above-mentioned light incontinence pad can diffuse liquid to the flange after absorbing liquid through the absorbing cotton, and the inner absorbing strip inside the flange can absorb liquid to make the flange swell and support, thereby achieving the effect of preventing side leakage. However, the flange swells and supports, which specifically means that the thickness of the two sides of the light incontinence pad in the width direction increases, and the two sides are located at the position of the thigh root of the human body. The flange with increased thickness will squeeze the thigh root of the human body, causing the user to feel obvious foreign body sensation and affecting the user's normal activities such as walking, thereby reducing the use comfort. Therefore, the disposable light incontinence pad still has room for improvement. UTILITY MODEL CONTENTS

[0029] As shown in FIGS. 1 and 2, a light incontinence pad with a side leakage prevention flexible partition comprises an absorption area 1 and a flexible partition 2, the width direction of the absorption area 1 is defined as the transverse direction, and the length direction is defined as the longitudinal direction, the absorption area 1 is sequentially composed of a surface layer 11, an absorption core 12 and a bottom film 13 from top to bottom, and the flexible partition 2 is located at the transverse edges of the absorption area 1 and extends along the longitudinal direction; the flexible partition 2 comprises the following structures: a wrapping layer 21, the wrapping layer 21 is folded downward from the edge of the surface layer 11 to below the bottom film 13 and is bonded to the lower surface of the bottom film 13, a wrapping cavity is formed between the top and the bottom of the wrapping layer 21, a composite structure layer 22 extending along the longitudinal direction is arranged in the wrapping cavity, the composite structure layer 22 is sequentially composed of a first partition interlayer 221, an elastic layer 222 and a second partition interlayer 223 from top to bottom, the first partition interlayer 221 is bonded to the top of the wrapping layer 21 at the transverse edges to form a first cavity between the top of the wrapping layer 21 and the first partition interlayer 221, and the elastic layer 222 is composed of at least one elastic spandex filament 2221 extending along the longitudinal direction; the top of the wrapping layer 21 is located above the composite structure layer 22, and the bottom of the wrapping layer 21 is located below the composite structure layer 22; at least one of the wrapping layer 21 and the first partition interlayer 221 has water repellency.

[0030] The light incontinence pad is used to assist the light incontinence patient in managing the discharge of urine in daily life, the surface layer 11 in the absorption area 1 is a structure close to the human genital organ and directly contacts the human genital organ, the surface layer 11 is selected from hot air non-woven fabric or spunlace non-woven fabric, the grammage of the non-woven fabric is 3-35 gsm, the two kinds of non-woven fabrics have good softness, air permeability and water absorption, which can make the surface of the light incontinence pad have good touch feeling and improve the use comfort, in addition, the urine discharged by the user when incontinence first contacts the surface layer 11, the surface layer 11 quickly absorbs and penetrates the urine into the absorption core 12 through good water absorption, and keeps the surface dry through good air permeability, further improving the use comfort of the light incontinence pad.

[0031] The absorbent core 12 in the absorption zone 1 is composed of an outer layer of non-woven fabric wrapping an inner absorbent material, wherein the outer layer of non-woven fabric is preferably a spun-bond non-woven fabric, which has good mechanical strength and can ensure the stability of the structure of the absorbent core 12. Meanwhile, the side of the absorbent core 12 close to the surface layer 11 is more preferably an SSS spun-bond non-woven fabric, which can quickly absorb and diffuse liquid and also prevent back seepage of liquid. When urine is absorbed and penetrates to the absorbent core 12 through the surface layer 11, it will first contact the SSS spun-bond non-woven fabric, which will quickly diffuse the urine to the inner absorbent material and be absorbed. In addition, the absorbent material is selected from one or more of fluff pulp, water-absorbing resin, and viscose fiber, which all have good water-absorbing properties and can firmly lock the absorbed liquid, ensuring the absorption performance of the light incontinence pad and preventing back seepage of the absorbed urine.

[0069] From the data in Table 1, it can be seen that the incontinence pad of Example 1 and the incontinence pad of Comparative Example 1 both have good side leakage prevention effect, the incontinence pad of Example 1 is to intercept the liquid which continues to spread horizontally by the flexible barrier and guide it to spread longitudinally, thereby achieving the side leakage prevention, while the incontinence pad of Comparative Example 1 is to absorb the liquid by the absorbing cotton in the flange and expand, thereby intercepting the liquid which continues to spread horizontally to achieve the side leakage prevention effect; in combination with the data in Table 2, it can be seen that the flexible barrier of the incontinence pad of Example 1 for side leakage prevention is upwardly convex, but its inside is mainly filled with air and has fluffiness and softness, so that the tester does not leave a pressure mark at the thigh root during wearing, and the comfort is good, while the incontinence pad of Comparative Example 1 is to form the structure for side leakage prevention by absorbing the liquid by the absorbing cotton and expanding, and the common absorbing materials such as water-absorbing resin, fluff pulp, viscose fiber and the like have a certain strength after absorbing the liquid, so that the tester will be pressed to form a pressure mark at the thigh root after wearing for a period of time, and has no feeling during wearing, and the comfort is poor.

[0070] The preferred embodiments described above are only the preferred embodiments of the present application, and it should be pointed out that, for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
