Description

Technical Field

[0001] This utility model relates to the field of disposable absorbent products, and in particular to a medical care pad with strong liquid absorption capacity. Background Technology

[0002] Nursing pads are easy to change and are used to absorb the excrement of paralyzed or temporarily incontinent individuals, reducing the frequency of bed changes and alleviating the burden on caregivers. Typical medical nursing pads consist of a skin-friendly surface, an absorbent layer, and a liquid-impermeable bottom layer, with a smooth surface. However, in cases of large single-time excretions, the absorbent layer cannot immediately absorb all the fluid, and excess liquid can easily leak laterally along the pad's surface onto the bed, soiling it.

[0003] To address the aforementioned issues, this case proposes a medical care pad with strong absorbency that prevents leakage into the mattress. Utility Model Content

[0004] Therefore, in view of the above problems, this utility model proposes a medical care pad with strong liquid absorption capacity to solve the problem of lateral leakage.

[0005] To solve the above-mentioned technical problems, the solution adopted by this utility model is as follows: a medical care pad with strong liquid absorption capacity, comprising a liquid-permeable surface layer, a first absorbent layer, and a liquid-impermeable bottom layer arranged sequentially from top to bottom, wherein the periphery of the liquid-permeable surface layer and the periphery of the liquid-impermeable bottom layer are heat-sealed, characterized in that: a first liquid-blocking ring is provided between the first absorbent layer and the liquid-permeable surface layer, which is connected end to end to prevent the lateral spread of liquid, the center of the first liquid-blocking ring coincides with the center of the first absorbent layer, and the first liquid-blocking ring arches the liquid-permeable surface layer upward to form a first liquid-blocking protrusion to prevent the lateral flow of liquid.

[0006] A further improvement is that a second liquid-blocking ring is provided between the first absorbent layer and the liquid-permeable surface layer, located outside the first liquid-blocking ring, which is connected end to end and used to prevent the liquid from spreading laterally. The center of the second liquid-blocking ring coincides with the center of the first liquid-blocking ring. The second liquid-blocking ring arches the liquid-permeable surface layer upward to form a second liquid-blocking protrusion for preventing the liquid from flowing laterally.

[0007] A further improvement is that a second absorption layer is laid on the upper surface of the first absorption layer inside the second liquid-blocking ring, and the first liquid-blocking ring is disposed on the upper surface of the second absorption layer.

[0008] A further improvement is that the first liquid-blocking ring and the second liquid-blocking ring are arranged in a U-shape.

[0009] A further improvement is that the first and second liquid-blocking rings are made by rolling up hydrophilic nonwoven fabric strips and superabsorbent polymer particles spread on the surface of the hydrophilic nonwoven fabric strips.

[0010] Further improvement is that the second absorption layer is composed of an upper water absorption paper layer, a water absorption polymer powder layer and a lower water absorption paper layer.

[0011] Further improvement is that the liquid permeable surface layer is a skin-friendly non-woven fabric layer.

[0012] Further improvement is that the first absorption layer is a polymer fluff pulp layer.

[0013] Further improvement is that the liquid impermeable bottom layer is a PE film layer.

[0014] By adopting the foregoing technical scheme, the utility model has the beneficial effects that:

[0015] The first liquid blocking ring arranged between the absorption layer and the surface layer arches the surface layer upward to form the first liquid blocking protrusion that hinders the lateral flow of the body fluid, and limits the drainage to the inside of the first liquid blocking protrusion to avoid flowing to the mattress, thereby giving the absorption layer time to absorb the drainage.

[0016] Further beneficial effect is that the second liquid blocking protrusion is arranged outside the first liquid blocking protrusion, and if the drainage flows out of the first liquid blocking protrusion, the second liquid blocking protrusion blocks the drainage, thereby further avoiding the drainage from flowing to the mattress and giving the absorption layer sufficient time to fully absorb the drainage.

[0017] Further beneficial effect is that the first liquid blocking ring and the second liquid blocking ring are made of the hydrophilic non-woven fabric strip and the polymer water absorption particles spread on the surface of the hydrophilic non-woven fabric strip, and when the first liquid blocking protrusion and the second liquid blocking protrusion block the drainage, the polymer water absorption particles also absorb the drainage, and the non-woven fabric strip can adapt to the swelling deformation of the polymer water absorption particles to increase the protrusion height of the first liquid blocking protrusion and the second liquid blocking protrusion, thereby further strengthening the liquid blocking effect.

[0018] Further beneficial effect is that the second absorption layer is arranged on the upper surface of the first absorption layer and inside the inner wall of the second liquid blocking ring to increase the absorption amount inside the second liquid blocking protrusion, and the first liquid blocking protrusion is arranged on the upper surface of the second absorption layer and still maintains the liquid blocking effect following the swelling of the second absorption layer, thereby avoiding the drainage from flowing to the mattress.

[0019] Further beneficial effect is that the second absorption layer is composed of an upper water absorption paper layer, a water absorption polymer powder layer and a lower water absorption paper layer, the water absorption paper has a high liquid absorption speed, can increase the downward infiltration speed of the drainage, accelerate the absorption efficiency of the drainage, and avoid the drainage from flowing to the mattress.
