The bed is placed on the bed or directly at the corners of the load-bearing frame to form a simple bed. The width of the mesh fabric 2 suspended between the two corresponding sides of the load-bearing frame 1 is greater than the width between the two corresponding sides by 1 mm to 20 mm. In order to better decompose the force when carrying the weight of the human body, the mesh fabric should be slightly concave and relaxed when suspended, and cannot be stretched. In order to prevent the mesh fabric 2 from being plastically stretched or broken. The preferred mesh diameter or mesh inscribed circle diameter of the mesh fabric 2 is less than 0.8 mm, the diameter and the weft diameter of the mesh are less than 0.27 mm, and the thickness of the mesh fabric is less than 0.55 mm. The mesh fabric 2 is inlaid with a mesh fabric 2 having a mesh diameter or a mesh inscribed circle diameter of less than 0.3 mm, a warp and weft diameter of less than 0.08 mm, and a thickness of less than 0.16 mm. Fine, especially for the damaged skin of patients. More specifically, the inlaid position corresponds to the wound where the patient is lying down, the inlaid area is larger than the wound area, and the nurse can spray the cleaning liquid or the liquid medicine through the mesh of the mesh fabric.

In addition, at the corresponding buttocks of the human body, a drain opening 23 may be opened, and the edge of the drain opening 23 also has a reinforcing layer 3 to reinforce the woven fabric 2 of the rim to avoid drawing or partial breakage.

In order to prevent the unformed excretion discharged from the anus by the premature or lactating infant or the like from the mesh bed, the excretory opening 23 is not provided at the corresponding human buttocks, but the mesh bed corresponds to the two thighs of the human body. A discharge discharge area consisting of a plurality of discharge holes arranged at a position close to the anus, the discharge area having an area of 1 to 30 square centimeters, consisting of a hole having a diameter of 1 to 5 mm; and an interval between the discharge hole and the discharge hole The distance is equal to 2 to 20 latitude and longitude diameters; the latitude and longitude lines of the discharge zone are continuous and cannot be broken; in order to keep the positional shape of the latitude and longitude lines and the discharge holes unchanged, the latitude and longitude lines of the discharge zone are bonded by flexible materials; The excrement is removed, and the anti-adhesive substance is covered on the front and back non-discharge holes of the mesh bed discharge area.

Referring to Fig. 2, the mesh fabric 2 is positioned adjacent to the load-bearing frame 1, corresponding to the curve of the human buttocks, having undulating undulations 25, and these wave pleats 25 are fixed in the reinforcing layer.

Referring to Fig. 3, the mesh fabric 2 is a fabric having meshes 22 which are interwoven by warp and weft threads 21. The intersection of the warp threads 21 and the weft threads 21 is relatively fixedly coupled, and can be fixed by an adhesive or heated and shaped. The adhesive fixing refers to any two adjacent intersections of the intersections of the warp and the weft of the mesh fabric 2, one of which is a fixed joint, and the other has no fixed joint, as shown by the dotted line in FIG. For the joint. This connection ensures that the front surface of the mesh fabric is smooth and will not be stained by the adhesive.

Among the various patterns woven by machine, square hole plain weave is the best choice of the present invention, and the square hole plain weave can obtain the best in the aspects of stretch resistance, easy cleaning, mesh opening and fabric thickness of the mesh fabric. The effect, but in the actual manufacturing process requirements, is recommended in the following range. The mesh fabric 2 is a single layer, and the plain weave structure interlaced on the warp and weft, the length error of the warp and weft constituting the mesh 22 is within plus or minus 20% of the nominal value, and constitutes the warp and weft between the mesh 22. The angle is greater than 60°. The above-mentioned one cell 22 means an open hole and a latitude and longitude line 21 surrounding the hole.

Referring to Fig. 4, the edge portion of the mesh fabric 2 or the portion of the cutting line is attached to the tensile reinforcing layer 3, by which the reinforcing layer 3 and the load-bearing frame 1 form a mutual positioning structure. The edges described herein include, in addition to the edges of the surrounding boundaries, the edges of the cut, the edges at the openings, and the like. Further, in the edge portion of the mesh fabric 2, particularly the edge portion in a suspended relationship with the load-bearing frame 1, the warp threads 21 or the weft yarns 21 are densely arranged and interwoven to increase the tensile strength of the edges.

The warp and weft threads 21 of the interwoven strips 24 having a comb-like or grid-like woven structure on the mesh fabric 2 are fixedly coupled to each other. One solution for joining is to print an adhesive on the stripes on the back side of the mesh fabric 2.

As shown in Fig. 4, the reinforcing layer 3 is composed of a substance applied to the mesh fabric 2, which completely or partially blocks the mesh 22 of the coated portion, specifically the edge is the most coated. Thick, completely block the mesh, as shown in the cover area 31 in Fig. 2; and gradually transition to the middle of the mesh fabric 2 to form a half-coverage area 32 in which the mesh portion is blocked, that is, the intersection of the latitude and longitude lines Covered with reinforcing substances. From full plugging to partial plugging to a small amount of plugging is a process of gradual reduction or step reduction, which is to prevent the sudden change of strength at the junction between the tensile strengthening layer and the non-tensile strengthening layer. The material used for coating is a flexible structural adhesive. The structural adhesive refers to a rubber which is superior to ordinary adhesives in terms of shear strength, tensile strength, peel strength, uneven tear strength, etc. The reinforcing layer 3 also includes a cover and a fixed mesh. The flexible fabric 33, the film, or the non-woven fabric on the fabric or covered and fixed on the material of the mesh fabric, may be one-sided, or both sides cover the flexible fabric 33, the strength is Raise to position the load-bearing frame 1.
