Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a breathable and sterile top bag. Background Technology

[0002] Top-end bags are a common type of packaging bag widely used in the medical field, often for packaging large surgical supplies, precision instruments such as cardiac and otorhinolaryngological catheters. Due to their high density and puncture resistance, top-end bags effectively protect these precision medical devices, providing a safe and sterile barrier.

[0003] In related technologies, top-end bags typically consist of a breathable paper side and a plastic film side. The breathable paper is usually made of Tyvek paper, and the plastic film is usually made of PE plastic film. The plastic film includes a top film and a bottom film integrally formed with the top film. The bottom film is located below the top film, and the length of the bottom film is longer than the length of the top film. The two length sides of the bottom film correspond one-to-one with the two length sides of the top film and are heat-pressed together so that the bottom film and the top film together form a bag with an opening. The breathable paper is laminated with the bottom film and is glued to the top film to seal the opening of the bag.

[0004] Regarding the above technology, the applicant believes that the following defects exist: the strength of the composite of breathable paper and bottom film is low. When the instrument inside the bag is heavy, the instrument will press on the composite of breathable paper and bottom film, which will cause the composite of breathable paper and bottom film to separate. The instrument is easy to fall out from the opening where the breathable paper and bottom film separate. Utility Model Content

[0005] The purpose of this application is to address the aforementioned problems existing in the prior art by proposing a breathable and sterilizable top bag.

[0006] This application can be achieved through the following technical solution: a breathable and sterilizable top bag, comprising a bottom film, a top film integrally formed with the bottom film, and a breathable paper, wherein an extension film is formed on the bottom film, the extension film is made of the same material as the bottom film, the breathable paper is provided on the extension film, and the breathable paper is adhered to the top film, the bottom film and the extension film.

[0007] In the above technical solution, an extension film is formed on the base film, and breathable paper is then placed on the extension film. When a heavy object is placed between the base film and the extension film, the support effect of the object between the extension film and the base film is better than that of the breathable paper and the base film being combined.

[0008] Furthermore, a transparent film is adhered to the surface of the bottom film away from the top film, forming an accommodating area between the bottom film and the transparent film, and a V-shaped cut is made on the transparent film.

[0009] In the above technical solution, a label containing the contents of the bag can be placed between the transparent film and the bottom film, and the V-shaped cut facilitates the removal of the label.

[0010] Furthermore, a marking film is provided between the transparent film and the base film.

[0011] In the above technical solution, staff can use a marker to mark the items inside the bag on the marking film. When the items inside the bag are changed, alcohol can be used to erase the marker marks and rewrite them.

[0012] Furthermore, the marking film is provided with anti-slip texture, which is positioned directly opposite the V-shaped cut.

[0013] In the above technical solution, the anti-slip texture makes it less likely for the hand to slip when removing the marking film.

[0014] Furthermore, a handle is provided on the bottom membrane.

[0015] In the above technical solution, the handle makes it easier for staff to pick up multiple top bags at the same time.

[0016] Furthermore, the handle includes a contact film and a stitching thread. The two length sides of the contact film are bent, and both ends of the contact film in the length direction are adhered to the base film. The two contact films are sewn together by the stitching thread.

[0017] In the above technical solution, when a person directly touches the contact film, the long side of the contact film is easy to scratch the person's hand. By bending the long side of the contact film, it is not easy for the person's hand to be scratched when touching the handle.

[0018] Furthermore, several anti-slip strips are installed on the bottom film.

[0019] In the above technical solution, by setting anti-slip strips, it is not easy for people to slip when their hands directly contact the bottom film.

[0020] Furthermore, both the top and bottom films are transparent.

[0021] In the above technical solution, both the top and bottom films are transparent, making it easy for staff to see the contents of the bag.

[0022] In summary, this application has the following technical advantages: an extension film is formed on the base film, and breathable paper is then placed on the extension film. When a heavy object is placed between the base film and the extension film, the support between the extension film and the base film is better than when the breathable paper is combined with the base film. A label indicating the contents of the bag can be placed between the transparent film and the base film, and the V-shaped cut facilitates label removal. Workers can use a marker to mark the contents of the bag on the marking film; when the contents of the bag are changed, the marker marks can be erased with alcohol and rewritten.

[0029] Reference Figure 1 , 2 One embodiment of this application provides a breathable and sterilizable top bag, comprising a transparent PE bottom film 1 and a top film 2, the top film 2 being integrally formed with the bottom film 1, and the bottom film 1 being longer than the top film 2. The two length sides of the bottom film 1 are heat-pressed together with the two length sides of the top film 2 in a one-to-one correspondence. An extension film 4 is integrally formed on the bottom film 1, located at the end of the bottom film 1 opposite to the top film 2 in the length direction, and the extension film 4 is spaced apart from the top film 2. The material of the extension film 4 is the same as that of the bottom film 1. The two width sides of the extension film 4 are heat-pressed onto the bottom film 1. A breathable paper 3, made of Tyvek paper, is installed on the extension film 4. The two length sides of the breathable paper 3 are glued to the top film 2 and the extension film 4 respectively, and the two width sides of the breathable paper 3 are glued to the top film 2, the bottom film 1, and the breathable paper 3.

[0030] Reference Figure 3 , 4A transparent film 5, made of polyethylene film, is adhered to the surface of the bottom film 1 facing away from the top film 2. The two length sides and one width side of the transparent film 5 are attached to the bottom film 1, creating an accommodating area between them. A V-shaped cut 51 is made on the transparent film 5. A marking film 6, also made of polyethylene film, is inserted between the transparent film 5 and the bottom film 1. Workers can use a marker to mark the items inside the bag on the marking film 6. When the items inside the bag are changed, the marker marks can be erased and rewritten using alcohol. The V-shaped cut 51 facilitates the removal of the marking film 6. The marking film 6 also has anti-slip textures 7, which are positioned opposite the V-shaped cut 51. These textures prevent slippage when workers manually remove the marking film 6.

[0031] Reference Figure 3 A handle 8 is attached to the surface of the bottom film 1 facing away from the top film 2. The handle 8 facilitates the simultaneous handling of multiple top bags by the staff, improving convenience. The handle 8 includes a contact film 81, with both ends of the contact film 81 attached to the bottom film 1 along its length. Both length sides of the contact film 81 are bent. The two layers of contact film 81 are sewn together by stitch 82. When a person directly touches the contact film 81, the length sides of the contact film 81 can easily scratch their hand. By bending the contact film 81 so that the hand touches the arc surface of the contact film 81, it is less likely to be scratched when the hand touches the handle 8.

[0032] Reference Figure 3 Multiple plastic anti-slip strips 9 are attached to the surface of the bottom film 1 that is away from the top film 2. When the handle 8 breaks, the person needs to directly contact the bottom film 1 to hold the bag. By setting the anti-slip strips 9, the person's hand will not slip when holding the bag.

[0033] The working principle of this embodiment is as follows: An extension film 4 is formed on the base film 1, and a breathable paper 3 is then placed on the extension film 4. When a heavy object is placed between the base film 1 and the extension film 4, the space between the extension film 4 and the base film 1 provides better support for the object compared to a composite of the breathable paper 3 and the base film 1. A label indicating the contents of the bag can be placed between the transparent film 5 and the base film 1, and the V-shaped cut 51 facilitates the removal of the label. Workers can use a marker to mark the contents of the bag on the marking film 6. When the contents of the bag are changed, the marker marks can be erased and rewritten using alcohol.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
