The mother Velcro 211 and the first child Velcro 161 can be adhered to each other.

[0040] Reference Figure 4 and Figure 5 When the width of the absorbent pad needs to be adjusted, the caregiver first removes the mother Velcro 211 from the first child Velcro 161, and then adjusts the width of the application part 11. After the adjustment is completed, the caregiver pinches the constraint edge 14 and the end corner of the application part 11 with one hand, and pulls the cotter pin 2 with the other hand, and the cotter pin 2 moves and presses against the first folding part 12 or the second folding part 13 again to re-form a new second fold 131, so that the second fold 131 is in the center of the first folding part 12 and the second folding part 13, ensuring that the liquid inlet surface 15 of the first folding part 12 and the second folding part 13 are completely in contact. Finally, the first folding part 12 and the second folding part 13 are fixed to the leakproof surface 16 of the application part 11 by the mother Velcro 211 and the first child Velcro 161, so as to improve the stability of the first folding part 12 and the second folding part 13.

[0041] In order to facilitate the folding and maintenance of the absorbent pad into a compact shape when recycling the used absorbent pad, refer to Figures 2 to 4, a second sub-velcro 162 is fixedly provided on the leakproof surface 16 of the constraint edge 14, and the mother Velcro 211 and the second sub-velcro 162 can be adhered to each other. When recycling the used absorbent pad, the mother Velcro 211 is separated from the first sub-velcro 161, and then the application part 11 is folded at least once, so that the liquid inlet surface 15 of the application part 11 is attached to each other. Then, the application part 11 is folded several times again, so that the width of the application part 11 is smaller than the width of the first folding part 12 and the second folding part 13, and finally, the application part 11, the first folding part 12, and the second folding part 13 are folded together, and the application part 11 is located inside the first folding part 12 and the second folding part 13, and the mother Velcro 211 and the second sub-velcro 162 are adhered to each other, so that the absorbent pad is folded into a compact shape and maintained, so as to prevent the accompanying personnel from accidentally contacting the liquid inlet surface 15 of the application part 11 when discarding the absorbent pad, and facilitate recycling.

[0042] In order to improve the overall performance and leak-proof effect of the absorbent pad, refer to Figure 1 and Figure 6 The absorbent pad body 1 includes an infiltration layer 17, an absorption layer 18, and a leakproof layer 19 which are sequentially stacked in the thickness direction. The infiltration layer 17 is used for allowing liquid to penetrate into the absorption layer 18, and the absorption layer 18 is used for absorbing the liquid infiltrated by the infiltration layer 17. The leakproof layer 19 is used to prevent the liquid in the absorption layer 18 from leaking out. The liquid inlet surface 15 is the side of the infiltration layer 17 away from the absorption layer 18, and the leakproof surface 16 is the side of the leakproof layer 19 away from the absorption layer 18. The edge of the absorbent pad body 1 is coated with a sealing strip 191, and the sealing strip 191 is used to prevent the liquid in the absorption layer 18 from leaking out. The sealing strip 191 is integrally formed at the edge of the leakproof layer 19, and the inner side of the sealing strip 191 is fixed to the edge of the infiltration layer 17 away from the absorption layer 18. The sealing strip 191, the infiltration layer 17, and the leakproof layer 19 are fixed by pressure melting.

[0043] Reference Figure 6 In this embodiment, the penetration layer 17 is made of non-woven fabric with good permeability, which can quickly allow liquid to penetrate through. The absorption layer 18 is made of highly absorbent resin material, which has strong liquid absorption and storage capabilities. The anti-leakage layer 19 is made of polyethylene film with excellent waterproof performance to effectively prevent liquid leakage. The penetration layer 17 allows liquid to penetrate into the absorption layer 18, and the absorption layer 18 can fully store the absorbed liquid, increasing the liquid absorption capacity of the absorbent pad. The anti-leakage layer 19 prevents liquid leakage and ensures that the bed surface is dry and clean.

[0044] The implementation principle of the embodiment of the present application is as follows: in actual use, when encountering a bed surface with a mismatched width, the position of the restraint belt 3 is changed by moving the restraint edge 14, thereby adjusting the position of the first fold 121, and realizing the change of the width of the application part 11 to adapt to the width of the bed surface. Then, the accompanying person pinches the end corners of the restraint edge 14 and the application part 11 with one hand, and pulls the cotter pin 2 with the other hand, and the cotter pin 2 moves and re-presses against the inside of the first folding part 12 or the second folding part 13 to re-form a new second fold 131. Make the second fold 131 in the center of the first folding part 12 and the second folding part 13 to ensure that the liquid inlet surface 15 of the first folding part 12 and the second folding part 13 are completely in contact. Finally, the first folding part 12 and the second folding part 13 are fixed to the leakproof surface 16 of the application part 11 by the mother Velcro 211 and the first child Velcro 161. The second folding part 13 always keeps contact with the liquid inlet surface 15 of the first folding part 12 to prevent liquid from seeping out.

[0045] The penetration layer 17 allows liquid to penetrate into the absorption layer 18, and the absorption layer 18 can fully store the absorbed liquid to increase the liquid absorption capacity of the absorbent pad. The leak-proof layer 19 prevents liquid leakage to ensure the dryness and cleanliness of the bed surface. The leak-proof layer 19 and the sealing strip 191 effectively prevent liquid leakage to ensure the leak-proof effect of the absorbent pad.

[0046] When recycling after use, the mother Velcro 211 is separated from the first child Velcro 161, and then the application part 11 is folded at least once to make the liquid inlet surface 15 of the application part 11 fit together. Then the application part 11 is folded several times to make the width of the application part 11 smaller than the width of the first folding part 12 and the second folding part 13. Finally, the application part 11, the first folding part 12, and the second folding part 13 are folded together, and the application part 11 is located inside the first folding part 12 and the second folding part 13, and the mother Velcro 211 and the second child Velcro 162 are adhered to each other, so that the absorbent pad is folded into a compact shape and maintained, so as to prevent the accompanying personnel from accidentally contacting the liquid inlet surface 15 of the application part 11 when discarding the absorbent pad, and facilitate recycling.
