In order to solve the technical problems, the utility model adopts the following technical scheme: the utility model provides a plastic dialysis sack with sterilization dialysis function, includes sack body and dialyzing paper, but sack body material is inwards one side at least and is heat seal plastics, dialyzing paper both sides scribble and be equipped with the glue film that can bond with plastics, the dialyzing window has been seted up to the sack body, dialyzing paper covers dialyzing window and is connected with sack body heat seal.
Further, the bag body is composed of two plastic composite films, each plastic composite film comprises a PE layer and a PCT layer, the PE layers and the PCT layers are overlapped and fixedly connected, and the two PE layers face each other.
Further, the dialysis paper is positioned in the bag body and connected with the PE layer of the plastic composite film in a heat sealing way.
Further, the dialysis window length is flush with the bag body width.
Compared with the prior art, the utility model has the following beneficial effects:
1. the plastic dialysis bag is characterized in that a dialysis window is formed in the bag body, dialysis paper is heat-sealed at the dialysis window, so that the bag body has a dialysis function and can be sterilized by adopting an ethylene oxide sterilization mode, compared with the existing plastic bag which is firstly filled with filler and then sterilized and finally sealed, strictly speaking, the plastic dialysis bag is in an open state after sterilization and during the period of sealing, bacteria can enter continuously in the gap, although the plastic bag is produced in a sterile environment, the probability of occurrence is small, but the plastic dialysis bag has a certain hidden trouble, and other substances cannot enter and exit (bacteria) uniformly except that ethylene oxide can enter and exit the bag body from the dialysis paper of the dialysis window during sterilization, so that the plastic dialysis bag in the scheme is better in sterilization effect and can truly reach the sterile state; compare in adopting the plastic bag that can adopt ethylene oxide to sterilize that dupont Tyvek made, plastic dialysis sack in this scheme low cost can make ordinary plastic bag have the dialysis sterilization function, and plastic dialysis sack in this scheme can be used to take up medical appliances such as cotton swab, gauze mask, operation package, gloves.
2. The dialysis window is located the tip of plastic composite film, and after the sack body formed, the dialysis window is close to sack body opening part, and the sack body is kept away from the rest of dialysis window and is all by plastic composite film for the sack body is when filling heavier article (such as metal object such as medical tweezers), and the filler is difficult to puncture dialyzing paper.

Detailed Description
In order to make the above features and advantages of the present utility model more comprehensible, embodiments accompanied with figures are described in detail below.
Example 1
As shown in fig. 1, 2 and 5, the present embodiment provides a plastic dialysis bag with a sterilization and dialysis function, comprising a bag body 1 and a dialysis paper 2.
The bag body 1 is formed by heat-sealing three sides of two plastic composite films 11, the plastic composite films 11 comprise a PE layer and a PCT layer, the PE layer and the PCT layer are overlapped and fixedly connected, the two PE layers face each other, a dialysis window is formed in any plastic composite film 11 of the bag body 1, the length of the dialysis window is flush with the width of the bag body 1, and the dialysis window separates one plastic composite film 11 into a first composite film 111 and a second composite film 112.
The dialysis paper 2 covers the dialysis window and is connected with the bag body 1 in a heat sealing way, two sides of the dialysis paper 2 are coated with adhesive layers which can be bonded with plastic, the two adhesive layers can be fully distributed on the surface of the dialysis paper 2 or circumferentially arranged along the periphery of the surface of the dialysis paper 2, and a gluing mode is selected according to the convenience degree of the production process. The dialysis paper 2 is located at the dialysis window and between two plastic composite films 11, one surface of the dialysis paper 2 is connected with the first composite film 111 and the second composite film 112 in a heat sealing way, the first composite film 111 and the second composite film 112 are respectively connected to the upper side and the lower side of the surface of the dialysis paper 2, a gap is formed between the first composite film 111 and the second composite film 112, the plastic composite film 11 with the dialysis window is formed after the dialysis paper 2 is connected with the first composite film 111 and the second composite film 112 in a heat sealing way, the plastic composite film 11 with the dialysis window is heat-sealed to the left side and the right side of the other plastic composite film 11, and a bag body 1 with an upper opening and a lower opening is formed, as shown in fig. 1 and 2, and the area of a section line of the plastic composite film 11 which is inclined rightwards is the heat-sealed area.
Any opening of the bag body 1 is heat sealed to form a three-seal plastic dialysis bag, leaving an opening for filling.
Preferably, in another embodiment, the inside of the heat-sealed opening may be provided with a zipper 12, so that its plastic dialysis bag becomes a zipper 12 plastic dialysis bag.
The dialysis window is formed in the bag body 1, and the dialysis paper 2 is heat-sealed at the dialysis window, so that the bag body 1 has a dialysis function and can be sterilized by adopting an ethylene oxide sterilization mode, and compared with the mode that a filler is firstly put into a plastic bag for sterilization and finally sealing is carried out, the plastic dialysis bag in the scheme has a better sterilization effect and can truly achieve a sterile state; compared with a plastic bag made of DuPont Tyvek and capable of being sterilized by using ethylene oxide, the plastic dialysis bag in the scheme is lower in cost, and the common plastic bag has a dialysis sterilization function.
