Description

Technical Field

[0001] This utility model relates to the field of leather technology, specifically to a biocompatible leather with good breathability. Background Technology

[0002] Biocompatible leather is generally made of silicone. Because silicone is composed of many tiny pores, these pores allow molecules such as gas and water vapor to pass through freely. Therefore, silicone leather has excellent skin-friendly properties and can be widely used in the biomedical industry. For example, biocompatible leather is laid on the surface of some equipment and instruments. Since the back of the biocompatible leather is in contact with the surface of the equipment and instruments, and the front of the biocompatible leather is in contact with the human body, the pores of the silicone are covered, which leads to a decrease in the breathability of the biocompatible leather. Utility Model Content

[0003] The technical problem to be solved by this invention is to provide a biocompatible leather with good breathability, addressing the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A biocompatible leather with good breathability includes a base layer, a foam layer, an intermediate base layer, and a silicone layer. The foam layer is disposed between the base layer and the intermediate base layer, and the silicone layer is disposed on the surface of the intermediate base layer. Ventilation holes are provided between the foam layers at intervals, and the width of the ventilation holes is greater than the thickness of the foam layers. A foam connecting strip is provided at the bottom of the ventilation holes, and the foam connecting strip connects the foam layers on both sides of the ventilation holes into a whole.

[0006] Furthermore, the lower and intermediate layers are made of non-woven fabric.

[0007] Furthermore, the foaming layer is made of PVC resin or polyurethane resin.

[0008] Compared with the prior art, the present invention provides a biocompatible leather with good breathability by setting a foam layer at the bottom of the silicone layer to improve the softness of the leather, and adding air pores on the surface of the foam layer to allow air to flow at the bottom of the silicone layer, thus ensuring the breathability of the leather. Attached Figure Description

[0009] Figure 1 This is a schematic diagram of the structure of this utility model;

[0010] The components are: 1. lower base layer, 2. foam layer, 3. intermediate base layer, 4. silicone layer, 5. vent holes, and 6. foam connecting strip. Detailed Implementation

[0011] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0012] like Figure 1 As shown, a biocompatible leather with good breathability includes a lower base layer 1, a foam layer 2, an intermediate base layer 3, and a silicone layer 4. The foam layer 2 is disposed between the lower base layer 1 and the intermediate base layer 3. The lower base layer 1 and the intermediate base layer 3 are made of non-woven fabric. The foam layer 2 is bonded between the lower base layer 1 and the intermediate base layer 3. The silicone layer 4 is disposed on the surface of the intermediate base layer 3 and is also bonded to the surface of the intermediate base layer 3. Ventilation holes 5 are provided at intervals between the foam layers 2. The ventilation holes 5 are located below the silicone layer 4, and the ventilation holes 5 allow air to flow at the bottom of the silicone layer, ensuring the breathability of the leather.

[0013] In this embodiment, the foam layer 2 is made of PVC resin or polyurethane resin to improve the softness of the leather. At the same time, when the leather is used, it is compressed and the foam layer will be compressed into the vent 5, reducing the area of ​​the vent 5. The width of the vent 5 is set to be greater than the thickness of the foam layer 2 to ensure that there are still air gaps between the foam layers after the leather is compressed.

[0014] A foam connecting strip 6 is provided at the bottom of the vent hole 5. The foam connecting strip 6 connects the foam layers on both sides of the vent hole 5 into a whole to ensure the strength of the foam layer 2.

[0015] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
