Description

Technical Field

[0001] This utility model relates to the field of medical sealing bags, and in particular to an easy-tear medical sealing bag. Background Technology

[0002] In the medical field, medical packaging bags, especially center-seal bags used to seal surgical instruments, dressings, and other items that require sterilization and must remain sterile, are widely used. These packaging bags typically consist of front and back films heat-sealed to form a closed inner cavity. They must have good sealing properties to block microorganisms, while also being easy for medical personnel to open quickly and safely in a sterile environment to access the contents.

[0003] Traditional medical packaging bags are typically opened by tearing open a pre-designed tear strip. However, this method has several inherent drawbacks: First, the tearing process is often difficult to control, easily resulting in uneven tear lines or even accidental tearing of unintended parts of the bag, compromising the integrity of the packaging and posing a risk of contamination to the contents. Second, debris generated during tearing may fall into the bag, threatening the sterile environment. Third, for certain instruments that need to maintain a specific shape or require sufficient space for removal, traditional tearing methods cannot provide a neat and controllable opening, causing inconvenience for users. Summary of the Invention

[0004] The purpose of this invention is to provide an easy-tear medical sealing bag that ensures the bag is torn along a preset tear path during opening, avoiding problems such as uneven tearing, tearing, or difficulty in tearing caused by uneven force, thus greatly improving the efficiency of opening the bag and making it highly efficient and convenient.

[0005] The technical solution to achieve the purpose of this utility model is as follows: This utility model has a bag body, which is formed by heat-sealing a front membrane layer and a rear membrane layer on each side. The bag body has a closed inner cavity. A vertically arranged dialysis paper strip is provided on the front membrane layer. The dialysis paper strip is placed in the inner cavity and is fixedly connected to the front membrane layer by two parallel and vertically arranged heat-sealed parts. The upper end of the dialysis paper strip is heat-sealed to the upper end of the bag body, and the lower end of the dialysis paper strip is heat-sealed to the lower end of the bag body, forming a dialysis space. Each heat-sealed part extends from the upper end of the bag body to the lower end of the bag body. The upper end of the dialysis paper strip also has an arc-shaped extension part, which is located above the bag body. The front membrane layer is provided with a group of punctures located between the heat-sealed sections. The group of punctures includes multiple punctures evenly distributed in the vertical direction. The extension direction of each puncture is the same as the extension direction of the dialysis paper tape, and each puncture is connected to the dialysis space. The front membrane layer is also provided with two groups of oppositely arranged virtual holes. Each virtual hole group is located at the heat-sealed section and the front membrane layer. Each virtual hole group includes multiple easy-open holes evenly distributed on the front membrane layer along the extension direction of the heat-sealed section. The easy-open holes at the upper end of each virtual hole group are connected to the arc-shaped extension through the side heat-sealing point. During the downward tearing process, the arc-shaped extension opens the closed bag through the guidance of each easy-open hole.

[0006] Furthermore, the aforementioned arc-shaped extension is provided with a snap hole, and the rear membrane layer is provided with a snap fastener. After the dialysis paper strip is torn off by the arc-shaped extension, it is fixed to the rear membrane layer by the cooperation of the snap hole and the snap fastener.

[0007] Furthermore, the aforementioned front membrane layer is provided with two parallel pull straps, each pull strap being parallel to the dialysis paper strip and located on both sides of the dialysis paper strip. The front membrane layer is provided with multiple rotating posts, with the upper end of each pull strap fitted onto the rotating post and the lower end of each pull strap also fitted onto the rotating post. Both the upper and lower ends of the pull straps are rotatably connected to the corresponding rotating posts. Each pull strap has a male buckle on the surface of the front membrane layer, and the rear membrane layer has a female buckle that matches each male buckle. When the bag is opened, the pull straps are pulled to both sides to open the bag. After being pulled to both sides, the pull straps are fixedly connected to the rear membrane layer through the cooperation of each male buckle and the corresponding female buckle.

[0008] Furthermore, a support assembly is provided between the aforementioned front and rear membrane layers, each support assembly comprising multiple support components evenly arranged within the bag body along the extension direction of the dialysis paper tape, which can support the inner cavity of the bag body after it is opened. Each support component includes a first support plate fixed to the front membrane layer and a second support plate fixed to the rear membrane layer. The extension directions of both the first and second support plates are perpendicular to the dialysis paper tape. The first support plate has a side slot, and the second support plate has a side insert. Both sides of the side slot... The bag is provided with side insertion holes, and the side insertion block is provided with side insertion rods that are adapted to each side insertion hole. The side insertion rods are rotatably set in the corresponding side insertion holes. Each side insertion rod is fitted with a torsion spring, and the two ends of the torsion spring act on the side insertion rod and the side insertion hole respectively. The first support plate is provided with a magnet, and the second support plate is provided with a magnetic locking block adapted to the magnet. Before the bag is opened, the first support plate is pressed against the second support plate by the cooperation of the magnet and the magnetic locking block. After the bag is opened and the magnet and the magnetic locking block are disengaged, the first support plate separates from the second support block and supports the inner cavity of the bag.

[0009] Furthermore, the bag body is provided with a hanging part integrally formed with the bag body, and the hanging part is provided with a hanging hole through which an external hook can pass.

[0010] This utility model has positive effects: (1) This utility model fixes the dialysis paper strip and a specific part of the front membrane layer covering it, namely the area between the two heat-sealed parts, by heat sealing, and sets a group of dummy holes at the edge as a guide, so that when tearing the arc-shaped extension, it is no longer just tearing off a narrow dialysis paper strip, but removing the entire dialysis paper strip and the front membrane layer composite strip as a whole from the bag. A large rectangular opening with neat edges and controllable size is created at the front of the bag, which greatly facilitates the access of the internal items. In the traditional design, if the dialysis paper strip and the plastic film are separate structures, there may be a risk that the plastic film will be torn and the dialysis paper strip will remain, or the two will separate and produce debris when tearing. However, this utility model first forms the dialysis paper strip and the front membrane layer as a whole. The composite unit ensures synchronous detachment during tearing, fundamentally avoiding potential debris contamination due to material delamination and guaranteeing a high degree of cleanliness during the opening process. Furthermore, this invention integrates the dialysis sterilization function with the item retrieval channel. During sterilization, it provides both ventilation and bacterial inhibition; during use, its location directly forms the retrieval channel. This simplifies the bag structure while achieving a high degree of unity and efficient conversion between functional areas and the opening channel. Simultaneously, the perforated group positions the tearing path. Because the mechanical strength and extensibility of the dialysis paper tape differ from pure plastic film, tearing along the perforations after lamination requires more stable and controllable force, providing a better tearing feel and preventing sudden breakage or deviation from the path. The structure is ingenious, convenient, and practical.

[0011] (2) By setting up the combination of buckles and buckle holes, the part above the dialysis paper strip on the membrane layer before the dialysis paper strip is torn off and fixed, so as to prevent it from floating around and contaminating the sterile area or hindering the operator from picking up the items, thereby ensuring the cleanliness of the work area.

[0012] (3) By setting a pull strap, the male and female buckles on the pull strap can actively open and fix the bag opening after the bag is opened, which can effectively prevent the bag from collapsing and closing due to its soft material, and improve the convenience of operators to take out items.

[0013] (4) This utility model sets multiple support components inside the bag. When the first support plate and the second support plate are not opened, they are positioned by magnetic attraction between the magnet and the magnetic lock block. As the bag is opened, the magnet and the magnetic lock block are disengaged. After the magnet and the magnetic lock block are disengaged, the first support plate and the second support plate are opened by the continuous force of each torsion spring, so that medical staff can directly and clearly see and take out all items, completing the perfect transformation from closed packaging to an ideal working interface, which is efficient and convenient.

[0014] (5) By setting up a hanging part, the present invention can hang the packaging bag before use, and also makes it convenient for operators to view the information on the packaging and the items inside the packaging, which is convenient and practical. Attached Figure Description

Detailed Implementation

[0016] See Figure 1 This utility model includes a bag body 1, which is formed by heat-sealing a front membrane layer 11 and a rear membrane layer 12 along their sides. The bag body 1 has a closed inner cavity. A vertically arranged dialysis paper strip 2 is provided on the front membrane layer 11 and is disposed within the inner cavity. The dialysis paper strip 2 is fixedly connected to the front membrane layer 11 by two parallel and vertically arranged heat-sealing parts 14. The upper end of the dialysis paper strip 2 is heat-sealed to the upper end of the bag body 1, and the lower end of the dialysis paper strip 2 is heat-sealed to the lower end of the bag body 1, forming a dialysis space. Each heat-sealing part 14 extends from the upper end of the bag body 1 to the lower end. An arc-shaped extension 21 is also provided at the upper end of the dialysis paper strip 2, located above the bag body 1. The front membrane layer 11 has... The puncture group is located between each heat-sealed part 14. The puncture group includes multiple puncture openings 13 evenly distributed in the vertical direction. The extension direction of each puncture opening 13 is the same as the extension direction of the dialysis paper strip 2, and each puncture opening 13 is connected to the dialysis space. The front membrane layer 11 is also provided with two sets of oppositely arranged virtual hole groups. Each virtual hole group is located at the heat-sealed part 14 and the front membrane layer 11. The virtual hole group includes multiple easy-open holes 15 evenly arranged on the front membrane layer 11 along the extension direction of the heat-sealed part 14. The easy-open holes 15 at the upper end of each virtual hole group are connected to the arc-shaped extension part 21 through the side heat-sealing point 23. During the downward tearing process, the arc-shaped extension part 21 opens the closed bag body 1 through the guidance of each easy-open hole 15.

[0017] By connecting the easy-open holes 15 at the top of each group of dummy holes to the side heat-sealing points 23, the arc-shaped extension 21 can be stably connected to the bag body 1 before tearing, and the overall sealing of the bag body 1 can also be guaranteed. In addition, the side heat-sealing points 23 can guide the arc-shaped extension 21 into the corresponding group of dummy holes during the tearing process, and tear it in an orderly and efficient manner along the tearing path, which is efficient and convenient.

[0018] The arc-shaped extension 21 is provided with a buckle hole 22, and the back membrane layer 12 is provided with a buckle 16. After the dialysis paper strip 2 is torn off by the arc-shaped extension 21, it is fixed to the back membrane layer 12 by the cooperation of the buckle hole 22 and the buckle 16.

[0019] The front membrane layer 11 is provided with two parallel pull straps 3, each pull strap 3 being parallel to the dialysis paper strip 2 and located on both sides of the dialysis paper strip 2. The front membrane layer 11 is provided with multiple rotating posts 31, the upper end of each pull strap 3 being sleeved on the rotating post 31, and the lower end of each pull strap 3 also being sleeved on the rotating post 31. The upper and lower ends of the pull strap 3 are rotatably connected to the corresponding rotating post 31. Each pull strap 3 has a male buckle 32 on the surface of the front membrane layer 11, and the rear membrane layer 12 has a female buckle 121 that matches each male buckle 32. When the bag body 1 is opened, the pull strap 3 is pulled to both sides and the bag body 1 is opened. After being pulled to both sides, the pull strap 3 is fixedly connected to the rear membrane layer 12 through the cooperation of each male buckle 32 and the corresponding female buckle 121.

[0020] A support assembly is provided between the front membrane layer 11 and the rear membrane layer 12. Each support assembly includes multiple support components 4 evenly arranged inside the bag body 1 along the extension direction of the dialysis paper strip 2, which can support the inner cavity of the bag body 1 after the bag body 1 is opened. Each support component 4 includes a first support plate 41 fixed to the front membrane layer 11 and a second support plate 42 fixed to the rear membrane layer 12. The extension directions of the first support plate 41 and the second support plate 42 are both perpendicular to the dialysis paper strip 2. The first support plate 41 is provided with a side slot 411, and the second support plate 42 is provided with a side insertion block 421. The side slot 411 has side insertion holes 412 on both sides. 421 is provided with a side insertion rod 422 adapted to each side insertion hole 412. The side insertion rod 422 is rotatably set in the corresponding side insertion hole 412. Each side insertion rod 422 is fitted with a torsion spring 423. The two ends of the torsion spring 423 act on the side insertion rod 422 and the side insertion hole 412 respectively. The first support plate 41 is provided with a magnet 43. The second support plate 42 is provided with a magnetic locking block 44 adapted to the magnet 43. Before the bag body 1 is opened, the first support plate 41 is pressed against the second support plate 42 through the cooperation of the magnet 43 and the magnetic locking block 44. After the bag body 1 is opened and the magnet 43 is disengaged from the magnetic locking block 44, the first support plate 41 separates from the second support plate and supports the inner cavity of the bag body 1.

[0021] The bag body 1 is provided with a hanging part 17 integrally formed with the bag body 1, and the hanging part 17 is provided with a hanging hole 18 through which an external hook can pass.

[0022] The working principle of this utility model is as follows: During use, the user first removes the bag 1 from the external hook. Then, when using it, pinch the arc-shaped extension 21 with two fingers and tear along the extension direction of each easy-open hole 15 on each perforated group. During tearing, the dialysis paper strip 2 and the front membrane layer 11 form an integral composite unit, ensuring synchronous detachment during tearing. This fundamentally avoids potential debris contamination due to material delamination, ensuring a high degree of cleanliness during the opening process. After tearing, the dialysis paper strip 2 is fixed to the rear membrane layer 12 through the fastening holes 22 and fasteners 16, preventing it from drifting and contaminating the sterile area or hindering the operator from retrieving the paper. This design ensures the cleanliness of the work area. After the bag 1 is opened, the operator can actively open and secure the bag opening using the various pull straps 3. This effectively prevents the bag 1 from collapsing and closing due to its soft material. The cooperation between the male buckle 32 and the female opening ensures the stability of the bag 1 after it is opened and prevents the pull straps 3 from falling off. During the process of the pull straps opening the bag 1, the magnetic block on the first support plate 41 disengages from the magnetic locking block 44 on the second support plate 42. Then, the first support plate 41 and the second support plate 42 continuously apply force through the torsion spring 423 to open the bag 1, ensuring the overall stability of the bag 1. This also makes it convenient for the operator to take out the items inside the bag 1. The structure is ingenious, efficient and convenient.
