Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging bag technology, specifically to a novel easy-tear film packaging bag for medical devices. Background Technology
[0002] In the field of medical device packaging, surgical medical devices, due to their large size and heavy weight, generally use adhesive-coated Tyvek easy-open packaging. However, due to the increasing implementation of centralized procurement, adhesive-coated Tyvek is particularly expensive, leaving very little room for cost reduction. Therefore, there is an urgent need for a low-cost, easy-open film medical device packaging bag as a replacement. Utility Model Content
[0003] The purpose of this utility model is to overcome the defects in the existing technology and provide a new type of easy-to-peel film medical device packaging bag, which can effectively solve the above-mentioned problems in the existing technology.
[0004] To achieve the above objectives, the technical solution of this utility model is to design a novel easy-tear film medical device packaging bag, which includes an upper film and a lower film, wherein the upper film and the lower film together form a bag body with one end open.
[0005] The upper film includes a first upper film, a second upper film, and a sealing film. An opening is formed between adjacent ends of the first upper film and the second upper film. The sealing film is located directly below the opening and is connected to the bottom of the first upper film and the second upper film.
[0006] Furthermore, it also includes a paper film, which is positioned directly above the opening and used to close the opening, and the paper film is connected to the top of the first upper film and the second upper film.
[0007] Furthermore, the end edge of the second upper membrane, which is parallel to the opening, is not connected to the lower membrane.
[0008] Furthermore, the sealing film is made of adhesive-free Tyvek.
[0009] Furthermore, the first and second upper films are made of easy-peel nylon film.
[0010] Furthermore, the lower mold is made of PE, PP or PET film.
[0011] Furthermore, the upper and lower films are connected by heat sealing or adhesive.
[0012] Furthermore, the sealing film is connected to the first upper film and the second upper film by heat sealing or adhesive.
[0013] Furthermore, the opening width is 2-5cm.
[0014] Furthermore, the first and second upper membranes are identical in shape and size and are symmetrically disposed on top of the lower membrane.
[0015] The advantages and beneficial effects of this utility model are as follows:
[0016] (1) In this utility model, the conventional breathable material Tyvek without glue has the advantages of being easy to open, breathable, strong, and having high antibacterial properties, and has a relatively obvious cost advantage. When combined with the film, it forms a new packaging bag that can be sterilized by gas, has higher puncture resistance and impact strength, and is lower in cost than the traditional glued Tyvek top bag, making it very suitable for the current trend of centralized procurement.
[0017] (2) This utility model integrates the features of gas sterilization and easy opening, and is suitable for low-cost gas-sterilizable medical device packaging. Using gas sterilization for the barrier device packaging bag of sterile barrier can reduce sterilization costs, reduce enterprise costs, and enhance competitiveness. The middle left and right sides are easy to open, the bag structure is simple, and it can be produced by ordinary three-axis feeding bag making equipment. Attached Figure Description
[0018] Figure 1 This is a structural schematic diagram of a novel easy-to-peel film medical device packaging bag as described in this utility model.
[0019] In the diagram: upper film 1, lower film 2, paper film 3, first upper film 11, second upper film 12, sealing film 13, opening 14. Detailed Implementation
[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0021] according to Figure 1 As shown, this utility model is a novel easy-tear film medical device packaging bag, which includes an upper film 1 and a lower film 2. The upper film 1 and the lower film 2 together form a bag body with one end open.
[0022] The upper film 1 includes a first upper film 11, a second upper film 12 and a sealing film 13. An opening 14 is formed between adjacent ends of the first upper film 11 and the second upper film 12. The sealing film 13 is located directly below the opening 14 and is connected to the bottom of the first upper film 11 and the second upper film 12.
[0023] In the above technical solution, the medical device is placed into the bag through the open end, then the open end is sealed, followed by gas sterilization. After sterilization, the bag is opened through the connection between the opening and the sealing film on both sides to remove the medical device. This invention utilizes conventional breathable, glue-free Tyvek material, which is easy to open, breathable, strong, and has high antibacterial properties, and also has a relatively significant cost advantage. Combined with a film, it forms a new type of packaging bag that can be gas-sterilized, has high puncture and impact resistance, and is relatively cheaper than traditional glued Tyvek top bags, making it very suitable for the current trend of centralized procurement.
[0024] In this invention, the direction parallel to the open end of the bag is the width direction, and the direction perpendicular to the open end of the bag is the length direction. In the width direction, the size of the sealing film 13 is greater than or equal to the size of the opening; in the length direction, the size of the sealing film 13 is greater than the size of the opening. In other words, the sealing film can completely close the opening.
[0025] As a preferred embodiment of the above technical solution, it further includes a paper film 3, which is disposed directly above the opening 14 and used to close the opening 14. The paper film 3 is connected to the top of the first upper film 11 and the second upper film 12. During gas sterilization, the paper film is removed.
[0026] As a preferred embodiment of the above technical solution, the end edge of the second upper membrane 12, which is parallel to the opening, is not connected to the lower membrane 2.
[0027] As a preferred embodiment of the above technical solution, the sealing film 13 is made of glue-free Tyvek.
[0028] As a preferred embodiment of the above technical solution, the first upper film 11 and the second upper film 12 are made of easy-to-peel nylon film.
[0029] As a preferred embodiment of the above technical solution, the lower mold 2 is made of PE, PP or PET film.
[0030] As a preferred embodiment of the above technical solution, the upper film 1 and the lower film 2 are connected by heat sealing or adhesive.
[0031] The sealing film 13 is connected to the first upper film 11 and the second upper film 12 by heat sealing or adhesive.
[0032] The opening 14 is 2-5 cm wide. The bag has a rectangular structure, and the distance between the first upper membrane and the second upper membrane is 2-5 cm to facilitate the removal of medical devices from the opening.
[0033] As a preferred embodiment of the above technical solution, the first upper membrane 11 and the second upper membrane 12 are identical in shape and size and are symmetrically disposed on the top of the lower membrane 2.
[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
