[0032] As shown in FIG. 1, a health care mesh bed of the invention comprises a bearing frame
1, and a net-shaped fabric 2 hang on the bearing frame 1. The bearing frame 1 is disposed
on a normal bedstead, or on a bedstead of a heat-insulating health care mesh bed with
a temperature and humidity regulating function, or legs are disposed at four corners
of the bearing frame 1 whereby forming a simple health care mesh bed. The width of
the net-shaped fabric 2 disposed between two edges of the bearing frame 1 is 1 mm
to 20 mm longer than that between the two edges. For better resolution of force applied
by a patient, the net-shaped fabric 2 is slightly concave and loose, and is not in
a tension state, so that elastic elongation or fracture does not occur. The diameter
or inscribed circle diameter of the mesh opening is less than 0.8 mm, the diameter
of the warp and the weft is less than 0.27 mm, and the thickness of the net-shaped
fabric is less than 0.55 mm. The diameter or inscribed circle diameter of the mesh
opening 22 on other part of the net-shaped fabric 2 is less than 0.3 mm, the diameter
of the warp and the weft 21 is less than 0.08 mm, and the thickness of the net-shaped
fabric 2 is less than 0.16 mm. The part of the net-shaped fabric 2 is more fine and
close, which is beneficial for wound of skin of the patient. In details, the part
is corresponding to wound that is pressed by the patient himself in bed, and an area
thereof is larger than a wound area. Nurses can spray cleaning fluid or liquor on
the wound via the mesh opening.
[0033] An outlet 23 is disposed at a hip of the patient, and a tensile layer 3 is disposed
at the edge of the outlet 23, whereby reinforcing the net-shaped fabric 2, and preventing
drawnwork or partial fracture.
[0034] To facilitate the discharge of shapeless excrement discharged from premature children
or nursing infants or something like that, no outlet 23 is arranged corresponding
to the human buttocks, but a discharge region formed by a plurality of discharge holes
is arranged corresponding to between two thighs and close to anus. The discharge region
has an area of 1-30 cm
2, comprising holes of 1-5 mm in diameter. The distance between two discharge holes
equals to the sum of the diameter of 2-20 warp and weft. The warp and weft in the
discharge region are continuous, without break. To fasten the position and shape of
the warp and weft and the discharge holes, the warp and weft are stuck by flexible
materials. To facilitate the removal of the excrement, anti-sticky materials are coated
on the non-discharge part of the face side and back side of the discharge region.
[0035] As shown in FIG. 2, edges of the net-shaped fabric 2 and the bearing frame 1 mutually
positioning each other correspond to hip curve of the patient, and each has a heave
and set wave ruffling 25, and the wave ruffling 25 is fixed in the tensile layer 3.
[0036] As shown in FIG. 3, the net-shaped fabric 2 comprises a mesh opening 22, and a warp
and a weft 21 interwoven in a vertical direction, an interweaving point of the warp
and the weft 21 is fastened by a fixed connection, adhesive, or heating. As the adhesive
is used, one of two adjacent interweaving points of the warp and the weft 21 is fastened
by a fixed connection, and the other one thereof is fastened by an unfixed connection
(as shown in a dashed line in FIG. 3). This ensure smooth surface of the net-shaped
fabric, and prevents the surface thereof from being contaminated by the adhesive.
[0037] In the invention, plain weave using square holes is used. Plain weave facilitates
optimum effect in terms of stretch proofing of the net-shaped fabric, easy cleaning,
the mesh opening, the thickness of the fabric, and so on. Preferably, the net-shaped
fabric 2 is a single-layered plain-weave structure interwoven by the warp and the
weft 21, an error in length of the warp and the weft 21 is within a range of ±20%
of a rating value, an angle between the warp and the weft 21 is greater than 60°.
The mesh opening 22 comprises an opening, and a warp and a weft 21 surrounding the
opening.
[0038] As shown in FIG. 4, a tensile layer 3 is disposed at the edge of the net-shaped fabric
2 or along a cutting line thereof, and the tensile layer 3 and the bearing frame 1
form a mutual positioning structure. The edge described hereinafter comprises surrounding
edges, cutting edges, edges at the opening, and so on. The warp and the weft 21 at
the edge of the net-shaped fabric, especially the edge hanging the bearing frame 1
are densely interwoven whereby improving tensile force at the edge.
[0039] As shown in FIG. 5, multiple warp interwoven strips 24 or weft interwoven strips
24 are disposed on the net-shaped fabric 2 in a direction of one of the strip or the
weft, or in directions of the strip and the weft, the width of the interwoven strip
24 is less than 3 mm, and the interwoven strips 24 are uniformly distributed on the
net-shaped fabric 2 and in the shape of a pectination or a grid, whereby improving
bearing capability and tensile capability of the fabric, and positioning performance
of the warp and the weft. The warp and the weft 21 on the interwoven strips 24 are
fastened via a fixed connection. In an embodiment, adhesive is disposed on strip at
the back of the net-shaped fabric 2 for connection.
[0040] As shown in FIG. 4, the tensile layer 3 is made of materials coated on the net-shaped
fabric 2, and parts or all of the materials block mesh openings 22 that are coated.
The edge of net-shaped fabric 2 is heavily coated, and the mesh opening is complexly
blocked, as indicated as a coverage area 31 in FIG. 2. The thickness of the net-shaped
fabric 2 becomes more thinner from the edge to the center thereof whereby forming
a half coverage area 32 in which the mesh opening is partially blocked. Strengthening
materials are coated on an intersection point between the warp and the weft, and thickness
thereof gradually decreases, or stepwisely decreases, whereby preventing intensity
catastrophe occurring at a junction between the tensile layer and the non-tensile
layer. The materials are soft flexible structure adhesive, which is better than normal
adhesive in terms of shear strength, tensile strength, peel strength, non-uniform
tear strength, and so on. The tensile layer 3 comprises one of a soft fabric 33, a
film, or a non-woven fabric that is coated and fixed on the net-shaped fabric 2, or
on the materials coated on the net-shaped fabric 2. The soft fabric 33 can be coated
on one side or both sides of the net-shaped fabric 2 whereby improving strength thereof
and implementing mutual positioning between the net-shaped fabric 2 and the bearing
frame 1.
[0041] As shown in FIGS. 1 and 6, mutual positioning between the net-shaped fabric 2 and
the bearing frame 1 is implemented by adhesion and is removable so that replacement,
disassembly or cleaning is convenient. The specific method is as follows:
[0042] 1. Multiple fixing edges 4 are disposed on the tensile layer 3 of edges of the net-shaped
fabric 2 and the bearing frame 1 mutually positioning each other, the fixing edge
4 comprises a sleeve 41 surrounded by the tensile layer 3, and a columnar pin 42 disposed
in the sleeve 41, and the bearing frame 1 comprises a cavity 11 operating to receive
the sleeve 41 and the columnar pin 42, and a groove 12 allowing the net-shaped fabric
2 to pass thereby. After the columnar pin 42 is pulled out, the net-shaped fabric
2 is separated from the bearing frame 1, which is suitable for a bed partially using
the net-shaped fabric 2. In details, the net-shaped fabric 2 in FIG. 1 is a whole
piece of net-shaped fabric 2, or a partially used net-shaped fabric 2, and is used
for a hip of a patient during cleaning of defecation, other parts thereof can use
normal fabrics that are assembled altogether.
[0043] 2. Multiple fixing edges 4 are disposed on the tensile layer 3 of edges of the net-shaped
fabric 2 and the bearing frame 1 mutually positioning each other, the fixing edge
4 is a tensile layer 3 fixed on a columnar pin 42, and the bearing frame 1 comprises
a cavity 11 operating to receive the fixing edges 4, and a groove 12 allowing the
net-shaped fabric 2 to pass thereby. The columnar pin 42 is fixed to the tensile layer
3, which features good integrity.
[0044] 3. A fixing edge 4 is a rigid strip 43 disposed on the tensile layer 3. As shown
in FIG. 5, the width of the rigid strip 43 is less than that of the tensile layer
3, the rigid strip 43 and the tensile layer 3 form a fixing edge 4, a hanging hole
44 is disposed on the fixing edge 4, a hanging column is disposed on the bearing frame
1, the hanging hole 44 and the hanging column form a removable positioning structure,
and a normal displacement of a fixing edge between adjacent hanging holes due to elastic
bending is less than 5 mm.
[0045] For example, the hanging holes 44 are uniformly disposed on the rigid strip 43, the
hanging column received in the hanging hole 44 is disposed on the bearing frame 1.
Mutual positioning between the hanging hole 44 and the hanging column makes disassembly
convenient and replacement simple.
[0046] 4. The simplest method is to fix the net-shaped fabric 2 on the bearing frame 1 along
the tensile layer 3 via adhesion whereby forming a mutual positioning structure. The
method features high requirement for operation of changing the net-shaped fabric,
and a simple structure.
[0047] To implement adjustment of tightness of the net-shaped fabric 2 on the bearing frame
1, the bearing frame 1 is a rectangular frame formed by a pair of long edges and a
pair of short edges, the distance between the long edges and that between the short
edges are adjustable, an adjusting range of the long edges is no greater than 6 cm,
an adjusting range of the short edges is no greater than 9 cm, the long edges simultaneously
move in a reverse direction and the short edges separately move during adjustment,

edges and a pair of short edges, the fixing edge comprising the columnar pin 42 are
capable of rotating a circumference less than 6 cm in a reverse direction in a cavity
11 formed by the long edges, and rotation of the fixing edge can be fixed at any position.
