S2, the first plastic composite film 21 and the second plastic composite film 22 are fixed with the dialysis paper body 1 in a heat sealing mode or the first plastic composite film 21 and the dialysis paper body 1 are fixed in a heat sealing mode, and the heat sealing temperature is 130-180 ℃.
Example 1
As shown in fig. 1 and fig. 3, the present solution provides a medical dialysis paper with two sides glued, which comprises a dialysis paper body 1, wherein one side of the dialysis paper body 1 is coated with a first glue layer capable of being bonded with a plastic film 2, the other side of the dialysis paper body 1 is coated with a second glue layer capable of being bonded with the plastic film 2, the plastic film 2 is a transparent film, at least one side of the plastic film 2 is made of heat-sealable plastic (such as pe material), the surfaces of the dialysis paper are covered with the first glue layer and the second glue layer, and specifically, the first glue layer and the second glue layer are made of water glue. The dialysis paper body 1 can be lapped (connected by heat sealing) with any plastic film 2 or plastic bag with a heat-sealable plastic surface (pe material surface), so that the plastic film 2 or plastic bag has the sterilization and dialysis functions. As shown in fig. 1, the area of the plastic film 2 where the cross-hatching is inclined to the right is an area of heat sealing.
The first adhesive layer and the second adhesive layer are respectively arranged on two sides of the dialysis paper body 1, because the medical plastic film 2 is generally a composite film, one side is the pe layer, the other side is the pet layer, only the pe layer can be bonded with the first adhesive layer or the second adhesive layer in a heat sealing way, like the existing dialysis paper body 1, only one side is provided with the adhesive layer, then the dialysis paper body 1 can be bonded with the plastic film 2 only, and the other side cannot be bonded with the plastic film 2 in a heat sealing way, so that the existing dialysis paper body 1 cannot be lapped with the plastic film 2.
Preferably, the first glue layer and the second glue layer are selected from high temperature resistant glue, so that the dialysis paper body 1 can be sterilized by steam sterilization after being lapped on the plastic bag (plastic film 2).
The plastic film 2 comprises a first plastic composite film 21 and a second plastic composite film 22, the first plastic composite film 21 is connected with a first adhesive layer, the second plastic composite film 22 is connected with the first adhesive layer, a gap is reserved between the first plastic composite film 21 and the second plastic composite film 22, the first plastic composite film 21 and the second plastic composite film 22 are upper and lower overlapped adhesive type composite films made of pe material and pet material, and one surface of the first plastic composite film 21 and the second plastic composite film 22 made of pe material is connected with the first adhesive layer of dialysis paper in a heat sealing mode.
As shown in fig. 2 and 4, the medical dialyzing paper produced in this embodiment may be heat sealed with three sides of a third plastic composite film 23 (made of the same material as the first plastic composite film 21 and the second plastic composite film 22) to form a plastic bag having a dialysis function as shown in fig. 2, and the area of the plastic film 2 where the cross-sectional line inclined to the right is a heat-sealed area.
Compared with the existing plastic bag with medical packaging, the plastic bag formed by three-side heat sealing of the medical dialyzing paper and the third plastic composite film 23 has the function of dialysis sterilization, the existing plastic bag is firstly filled with filler, then sterilized and finally sealed, and strictly speaking, the plastic bag is in an open state after sterilization and during the period of sealing, bacteria can enter continuously in the gap, although the bag is produced in a sterile environment, the probability of occurrence is small, but the problem is still that the plastic dialyzing bag has certain hidden trouble, in the scheme, the opening of the bag is in the sealed state in the sterilization process, except that ethylene oxide can enter the plastic dialyzing bag from the dialyzing paper body 1, other things can not enter the plastic dialyzing bag (particularly bacteria) uniformly, and the ethylene oxide inactivates the bacteria in the plastic dialyzing bag and then comes out from the dialyzing paper body 1, so that the sterility in the bag is truly achieved.
In addition, compared with a plastic dialysis bag made of DuPont Tyvek and capable of being sterilized by using ethylene oxide, the plastic dialysis bag made of the medical dialysis paper is lower in cost, and the common plastic bag has a dialysis sterilization function through the lap joint of the medical dialysis paper and the plastic film 2.
Example 2
As shown in fig. 5 and 6, the difference between the present embodiment and embodiment 1 is that the dialysis paper body 1 is directly connected with the first plastic composite film 21 by heat sealing, the medical dialysis paper produced in this embodiment can be three-sided heat-sealed with the third plastic composite film 23 (the material is the same as that of the first plastic composite film 21) to form a plastic bag (plastic dialysis bag) with dialysis function as shown in the figure, and the functions and beneficial effects are the same as those of the plastic bag (plastic dialysis bag) with dialysis function in embodiment 1, and the area of the plastic film 2 with a right inclined cross-section line is the heat-sealed area as shown in fig. 5 and 6.
The scheme also provides a production process of the plastic dialysis bag, which comprises the following steps:
s1, cutting a plastic film 2, cutting off one end of the plastic film 2, which is to be lapped with the dialysis paper body 1, and forming a first plastic composite film 21 and a second plastic composite film 22 or the first plastic composite film 21 by the plastic film 2;
s2, carrying out lap-joint heat seal on the first plastic composite film 21 and the second plastic composite film 22 and the dialysis paper body 1 or carrying out lap-joint heat seal on the first plastic composite film 21 and the dialysis paper body 1;
s3, pulling out a new roll of plastic film 2, and carrying out bilateral heat sealing on the new roll of plastic film 2, the first plastic composite film 21 and the second plastic composite film 22 with the dialysis paper body 1 to form a plastic dialysis bag with two open ends;
s4, performing heat sealing at any opening of the plastic dialysis bag or performing heat sealing after a zipper is arranged at any opening of the plastic dialysis bag.
In the plastic dialysis bag made of the dialysis paper in the embodiment, after the plastic dialysis bag is formed, the dialysis window is close to the opening of the bag body, so that the plastic dialysis bag can be used for principle of the dialysis paper body 1 when being filled with heavy articles (such as metal articles like medical forceps) and the like, and the filler is packaged in the plastic dialysis bag, so that the dialysis paper body 1 is not easy to be pricked.
While the basic principles and main features of the invention and advantages of the invention have been shown and described, it will be understood by those skilled in the art that the present invention is not limited by the foregoing embodiments, which are described in the foregoing description merely illustrate the principles of the invention, and various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims and their equivalents.
