[0034] Incontinence-associated dermatitis (IAD) refers to skin damage caused by continuous exposure to urine or feces, and is common in patients with diarrhea, incontinence, or urostomy. The occurrence of incontinence dermatitis not only increases the pain and discomfort of patients, but also prolongs their hospitalization time and increases medical expenses.

[0035] In the related art, sterile gauze soaked in vegetable oil is used clinically to wipe the patient's skin. However, during the wiping process, dirt will penetrate into the gauze and contaminate the vegetable oil, affecting the use effect.

[0036] In response to the above problems, an embodiment of the present application provides a medical non-woven fabric that can prevent dirt from penetrating into the non-woven fabric and contaminating the care oil during the wiping process, thereby effectively treating and preventing incontinence dermatitis.

[0037] The technical solution of the embodiments of the present application is described in detail below with reference to the accompanying drawings.

[0038] Figure 1 It is a schematic diagram of the structure of the medical nonwoven fabric shown in the embodiment of the present application.

[0039] See also Figure 1 The embodiment of the present application provides a medical non-woven fabric, including an outer layer 1 and a core layer 2, the core layer 2 is arranged in the outer layer 1, and the core layer 2 includes a plurality of oil-conducting structures 20 arranged at intervals along its extension direction, the oil-conducting structure 20 includes an oil storage layer 200 and a single-channel layer 201, the oil storage layer 200 and the single-channel layer 201 are stacked along the thickness direction of the core layer 2, and are respectively located on the skin-distal side 10 and the skin-proximal side 11 of the outer layer 1, and the single-channel layer 201 is configured to allow the care oil in the oil storage layer 200 to seep out from the skin-proximal side of the outer layer 1; and, the plurality of oil-conducting structures 20 separate the core layer 2 and form a plurality of guide channels 21, and the guide channels 21 are configured to allow dirt to penetrate from the skin-proximal side 11 of the outer layer 1.

[0040] The outer layer 1 of the medical nonwoven fabric of the present application embodiment has two opposite sides in the thickness direction, namely, a skin-distal side 10 and a skin-proximal side 11 ( Figure 1 The skin-proximal side 11 is used for contacting with the patient's skin, and the skin-distal side 10 is used for contacting with the hands of medical staff.

[0041] The oil storage layer 200 in the embodiment of the present application can be prepared by impregnating non-woven fabric with vegetable oil or edible oil (such as sesame oil, sesame oil). The single channel layer 201 can be prepared by a one-way filter membrane, the pore size of which is larger than the particle size of the oil molecules in the oil storage layer 200 and smaller than the particle size of the skin dirt, so that only the care oil in the oil storage layer 200 is allowed to seep out, and dirt is not allowed to seep into the oil storage layer 200, thereby preventing dirt from entering the oil storage layer 200 and contaminating the care oil stored in the oil storage layer 200. Moreover, when a certain amount of dirt penetrates from the skin-proximal side of the outer layer 1, since the guide channel 21 has a larger channel than the oil guide structure 20, most of the dirt will directly penetrate into the medical non-woven fabric through the guide channel 21, and since the oil guide structure 20 and the guide channel 21 are arranged at intervals, even if the dirt penetrates into the guide channel 21, it will not enter the oil storage layer 200, further preventing the care oil stored in the oil storage layer 200 from being contaminated.

[0042] As can be seen from the above, the core layer 2 of the medical non-woven fabric in the embodiment of the present application includes an oil guide structure 20 and a flow guide channel 21 that are arranged at intervals. The single channel layer 201 included in the oil guide structure 20 only allows the care oil in the oil storage layer 200 to pass through and seep out from the skin-proximal side 11 of the outer layer 1. When wiping the patient's skin, the care oil comes into contact with the patient's skin, thereby playing a role in treating and preventing incontinence dermatitis; wherein the setting of the flow guide channel 21 allows dirt generated by wiping the patient's skin to enter. Since the flow guide channel 21 is spaced apart from the oil guide structure 20, most of the dirt will penetrate into the flow guide channel 21, but will not enter the oil storage layer 200, thereby preventing the care oil in the oil storage layer 200 from being contaminated, thereby achieving the effect of continuously and effectively protecting the patient's skin.

[0043] In addition, the core layer 2 may also include a protective structure, which is arranged outside the oil guide structure 20 to isolate the oil guide structure 20 from the flow guide channel 21 more thoroughly, so as to prevent a small amount of dirt entering the flow guide channel 21 from penetrating into the oil storage layer 200 when there is excessive dirt. The protective structure may be made of a waterproof non-woven fabric containing resin glue.

[0044] As an optional embodiment, the oil guiding structure 20 further includes an antibacterial layer 202 , and the antibacterial layer 202 is disposed on a side of the single channel layer 201 away from the oil storage layer 200 .

[0049] The skin-friendly layer 203 of the embodiment of the present application and the skin-proximal side 11 of the outer layer 1 can be an integrally formed structure, which can reduce the process flow and save production costs. The skin-friendly layer 203 is in direct contact with the patient's skin, which can reduce damage to the patient's skin and relieve the patient's pain.

[0050] As a preferred embodiment, the skin-friendly layer 203 is made of mesh cloth containing a cotton wool layer.

[0051] The skin-friendly layer 203 of the embodiment of the present application contains a cotton wool layer, which is soft and skin-friendly and reduces damage to the skin; the mesh material can increase the air permeability of the skin.

[0052] In addition, the skin-friendly layer 203 of the embodiment of the present application may also adopt a concave-convex structure, wherein the concave portion is conducive to the slippery diffusion of the liquid, and the convex portion is conducive to reducing the contact area with the human skin and enhancing the air permeability.

[0053] As an optional embodiment, the skin-distal side 10 of the outer layer 1 is convex toward the core layer 2 to form a plurality of extrusion portions 12 , and the extrusion portions 12 are arranged corresponding to the oil storage layer 200 .

[0054] Each oil storage layer 200 of the embodiment of the present application corresponds to at least one extrusion portion 12. When medical staff use the non-woven fabric, their hands are in contact with the skin-distal side 10 of the outer layer 1. During the process of wiping the patient's skin, an extrusion force is generated on their hands. The extrusion portion 12 can transfer the extrusion force to the oil storage layer 200, and squeeze the oil storage layer 200, so that the care oil in the oil storage layer 200 seeps out toward the skin-distal side 11, thereby achieving continuous oil discharge.
