Description
Technical field
The present invention relates to field of medical technology, and in particular to a kind of flange edge sealing process of bandage.
Background technique
In ventilator bandage industry, it is divided into edge sealing and not two kinds of edge sealing.Wherein the major part of edge sealing is all ultrasonic wave envelope
Side, but ultrasonic wave edge sealing size has limitation, do not seal it is too big, can only sectional envelope, thus cause production plus
Work is at high cost, the defect of low efficiency；Since bandage is because needing to contact with wearer's skin, edge sealing bandage is not worn be easy for a long time
Generation face trace causes discomfort to wearer, it would be highly desirable to improve.
Summary of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of flange for designing reasonable bandage
Edge sealing process carries out bound edge using bottom excess stock turnup to another side, then sharp compound one layer of material again, to reach
Edge sealing effect will not cause face trace using edge sealing bandage made of the technique to wearer.
In order to achieve the above objectives, present invention employs following technical proposals: its operating procedure is as follows:
1, first required shape will be cut into a thickness of the elastic foam of 2-4mm, then cloth fabric is cut into institute
The shape needed, and make the unilateral than the unilateral narrow 5-8mm of the cloth fabric cut of the elastic foam cut；
2, the elastic foam cut is bonded with the cloth fabric cut；
3, the cloth fabric cut in step 1 is turned down along the edge of the elastic foam cut toward upper surface and is pasted
It closes, forms semi-finished product；
4, composite layer is cut into required shape, and makes the width of the composite layer cut than cutting
The unilateral narrow 2-5mm of good elastic foam；
5, the composite layer cut is fitted in the upper surface of the semi-finished product in step 3.
Further, the fitting in the step 2 is using fire patch, sticker mode.
Further, the edge of the composite layer cut in the step 4 can be covered in step 3 and turned over
The cloth fabric cut flange position.
Further, the laminating type in the step 5 is hot pressing gluing.
Further, the thickness of the outer edge of composite layer gradually successively decreases setting from inside to outside in the step 4.
Further, the composite layer is silica gel or plastic cement.
The working principle of this specific embodiment:: using on the excess stock turnup to upper one layer of another side of bottom, into
Row bound edge finally recycles composite layer that top layer is had being bonded on one side for flange, thus reach edge sealing effect, due to
The edge of top layer flange effectively block by composite layer, so that bandage is both provided with edge sealing, in turn avoids one section one
Troublesome operation caused by section edge sealing.
After above-mentioned technique, the beneficial effects of the present invention are: the present invention provides a kind of flange edge sealing process of bandage,
It carries out bound edge using bottom excess stock turnup to another side, then sharp compound one layer of material again, thus reach edge sealing effect,
Face trace will not be caused to wearer using edge sealing bandage made of the technique.
Detailed description of the invention:
Fig. 1 is the structural decomposition diagram of bandage made of the present invention.
Fig. 2 is the sectional view of bandage made of the present invention.
Fig. 3 is the structural schematic diagram of bandage made of the present invention.
Description of symbols:
Composite layer 1, elastic foam 2, cloth fabric 3.
Specific embodiment:
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1-Figure 3, present embodiment adopts the following technical scheme that its operating procedure is as follows:
1, first will cut into shape as shown in figure 1 with a thickness of the elastic foam 2 of 3mm, then by cloth fabric 3 cut into as
Shape in Fig. 1, and make the unilateral than the unilateral narrow 6mm of the cloth fabric 3 cut of the elastic foam cut 2；
2, the elastic foam 2 cut is bonded with the cloth fabric 3 cut using sticker mode；
3, the cloth fabric 3 cut in step 1 is turned down along the edge of the elastic foam 2 cut toward upper surface
It is bonded afterwards using sticker mode, forms semi-finished product；
4, composite layer (its material is plastic cement or silica gel) is cut into shape as shown in figure 1, composite layer 1
The thickness of outer edge gradually successively decreases setting from inside to outside, and makes the width of the composite layer cut 1 than the bullet that cuts
The unilateral narrow 3mm of property foaming body, the edge of the composite layer 1 cut can cover cutting of having turned in step 3
Cloth fabric 3 flange position；
5, utilize hot pressing glue together in the upper surface of the semi-finished product in step 3 composite layer 1 cut, i.e.,
It can.
The working principle of this specific embodiment:: it is arrived using excess stock (i.e. the outer edge of cloth fabric) turnup of bottom
On the another side of upper one layer (i.e. elastic foam), bound edge is carried out, finally recycles composite layer (i.e. silica gel or plastic cement material
Matter) there is flange to be bonded on one side top layer, to reach edge sealing effect, since composite layer is by the side of top layer flange
Edge effectively block, so that bandage is both provided with edge sealing, in turn avoids troublesome operation caused by one section of one section of edge sealing.
After above-mentioned technique structure, the beneficial effect of present embodiment is: present embodiment provides one kind
The flange edge sealing process of bandage carries out bound edge using bottom excess stock turnup to another side, then sharp compound one layer of material again
Matter will not cause face trace using edge sealing bandage made of the technique to reach edge sealing effect to wearer.
Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art,
It is still possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is carried out etc.
With replacement, all within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection scope of invention.
