Description

Technical Field

[0001] The utility model relates to the field of medical sterilization packaging, and more particularly to a medical sterilization paper-plastic bag capable of preventing accumulation of condensed water. Background Art

[0002] Medical sterilization paper-plastic bags, with medical dialysis paper on one side and a transparent composite film on the other, are sealed and bonded together to form packaging bags suitable for sterilization using specified sterilization methods. During sterilization, the medical dialysis paper surface facilitates the entry and exit of sterilization media, while the transparent composite film allows for easy inspection of the contents. Due to their extended sterility retention period after sterilization and their ease of use, these sterilization paper-plastic bags are highly favored by users.

[0003] However, during pressure steam sterilization, especially for metal objects, a large amount of condensation water will be generated. Traditional medical sterilization paper and plastic bags are prone to accumulation of condensation water, resulting in a high probability of "wet bags", which in turn leads to sterilization failure. Utility Model Content

[0004] The utility model aims to provide a medical sterilization paper-plastic bag which can prevent the accumulation of condensed water, thereby solving the problem of condensed water accumulation in the prior art medical sterilization paper-plastic bags during steam sterilization.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] Provided is a medical sterilization paper-plastic bag for preventing accumulation of condensed water. The medical sterilization paper-plastic bag is formed by connecting medical dialysis paper and a transparent composite film by sealing on three sides. The unsealed portion forms the bag opening, and the portion opposite to the bag opening is the bag bottom. The inner side of the transparent composite film is sealed and connected with a water-absorbing non-woven fabric strip for absorbing condensed water generated in the bag during pressure steam sterilization.

[0007] Preferably, the water-absorbent non-woven fabric strips are made of polypropylene.

[0008] Preferably, the weight of the water-absorbing nonwoven fabric strip is 45 g / m 2 ~65g / m 2 .

[0009] Preferably, there are two water-absorbent non-woven fabric strips.

[0010] Preferably, the two water-absorbent nonwoven fabric strips extend in parallel with a certain interval.

[0011] Preferably, the sum of the widths of the water-absorbing non-woven fabric strips is less than 2 / 3 of the width of the corresponding transparent composite film of the bag body.

[0012] Preferably, the width of the water-absorbent non-woven fabric strip is 50 to 150 mm.

[0013] Preferably, the transparent composite film is formed by compounding a PET film (polyester film) and a RCPP film (high temperature resistant cast polypropylene film).

[0014] Preferably, the bag bottom is formed into a V-shaped bag bottom by sealing and connecting.

[0015] Preferably, the distance between the outermost edge of the hot-sealed and bonded connection of the V-shaped bag bottom and the bottom edge of the bag body is 8 to 15 mm.

[0016] As mentioned in the Background Technology section, traditional medical sterilization paper-plastic bags are prone to generating large amounts of condensed water that is difficult to evaporate within the bag during pressure steam sterilization, particularly when sterilizing metal medical devices. This condensed water also tends to accumulate, making it difficult to dry and resulting in wet bags. Adding absorbent nonwoven fabric strips to designated locations within the paper-plastic bag can prevent condensed water accumulation during pressure steam sterilization and improve local physical properties.

[0017] This utility model seals and hot-bonds two water-absorbing non-woven fabric strips onto the transparent composite film within the cavity of a conventional medical sterilization paper-plastic bag. The water-absorbing non-woven fabric strips are made of the same polypropylene material as the inner layer of the transparent composite film. This facilitates the sealing and hot-bonding of the water-absorbing non-woven fabric strips to the transparent composite film while also being able to withstand the temperatures experienced during pressure steam sterilization. During pressure steam sterilization, condensed water generated within the bag is readily absorbed by the water-absorbing non-woven fabric, preventing condensed water accumulation that could affect drying and cause a wet bag. This also enhances local physical properties, preventing damage to the transparent composite film by medical instruments and items.

[0018] The medical sterilization paper-plastic bag provided by the present invention for preventing accumulation of condensed water has the following beneficial effects compared with the prior art:

[0019] 1) After adding the absorbent non-woven fabric strips, the condensed water generated during pressure steam sterilization can be absorbed in time to avoid the accumulation of condensed water, which affects drying and causes wet packs;

[0020] 2) The absorbent non-woven fabric strips can not only absorb condensed water, but also enhance the local physical properties, improve the tear resistance of the transparent composite film, and reduce the probability of damage to the transparent composite film;

[0021] 3) The water-absorbing non-woven fabric is sealed and bonded in a fixed position, and will not be moved or wrinkled or overlapped, which will reduce the water absorption effect or make the overlap difficult to dry;

[0022] 4) No additional padding or absorbent paper is required during packaging, which is convenient to operate. Just seal the package in the traditional paper-plastic bag.

[0023] In summary, the utility model provides a medical sterilization paper-plastic bag which can effectively avoid the accumulation of condensed water in the bag body during steam sterilization, has enhanced local physical properties, and is easy to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] like Figures 1 and 2As shown in FIG, a medical sterilization paper plastic bag for preventing condensation water accumulation is provided according to a preferred embodiment of the present invention. The medical sterilization paper plastic bag is made of medical dialysis paper 1 and transparent composite film 2 connected by three-side hot sealing. The medical dialysis paper 1 is made of 60-80g / m 2 The medical high-temperature dialysis paper and the transparent composite film 2 are made of a PET (polyester film) / RCPP (high-temperature resistant cast polypropylene film) composite film with a total thickness of 50-70 μm. The medical dialysis paper 1 and the transparent composite film 2 are connected by heat sealing. The unsealed portion forms the bag opening 6, and the portion opposite the bag opening is sealed to form a V-shaped bag bottom 5. The two sides are sealed to form a first sealed adhesive connection portion 3 and a second sealed adhesive connection portion 4. The V-shaped bag bottom 5 also serves as the opening for removing the sterilized medical device from the paper-plastic bag. The outermost edge of the V-shaped bag bottom 5 is 8-15 mm from the bottom edge of the bag body, making it convenient for both hands to handle the medical dialysis paper 1 and the transparent composite film 2 during opening.

[0032] On the surface of the transparent composite film 2 inside the cavity of the paper-plastic bag, a first water-absorbing non-woven fabric strip 7 and a second water-absorbing non-woven fabric strip 8 are respectively sealed and bonded. The two edges of the first water-absorbing non-woven fabric strip 7 are respectively bonded to the transparent composite film 2 by a third sealing and bonding connecting portion 71 and a fourth sealing and bonding connecting portion 72. The two edges of the second water-absorbing non-woven fabric strip 8 are respectively bonded to the transparent composite film 2 by a fifth sealing and bonding connecting portion 81 and a sixth sealing and bonding connecting portion 82.

[0033] It should be understood that the absorbent non-woven fabric strip is preferably made of the same polypropylene material as the inner layer of the transparent composite film. On the one hand, it is convenient for the sealing and hot bonding of the absorbent non-woven fabric strip and the transparent composite film, and on the other hand, it can withstand the temperature during pressure steam sterilization. According to this preferred embodiment, the absorbent non-woven fabric strip is selected to be 45-65g / m 2 Polypropylene absorbent non-woven fabric.

[0034] According to this preferred embodiment, the widths of the first water-absorbent non-woven fabric strip 7 and the second water-absorbent non-woven fabric strip 8 are respectively 50 to 150 mm.
