Description

Technical Field

[0001] This utility model relates to the field of medical packaging bags, and in particular to a medical packaging bag with reinforced bottom support. Background Technology

[0002] In the medical field, medical packaging bags are widely used for the sterilization, storage, and transportation of sterile medical devices. These packaging bags not only need to have good antibacterial properties to ensure the sterility of the contents within their expiration date, but also need to have a certain physical strength to withstand pressure changes during the sterilization process (such as high-temperature steam sterilization) as well as external forces such as stacking and compression during subsequent transportation and storage.

[0003] Traditional medical packaging bags are typically formed by heat-sealing the front and back films, with an opening and self-sealing structure at the top for easy access to items. To meet the permeation requirements of sterilization media such as steam, one or more sides of the bag are made of dialysis material. However, while providing good air permeability, this type of dialysis material has relatively weak structural rigidity and puncture resistance. When the bag is laid flat or contains medical devices with considerable weight or sharp edges, the bottom of the bag, especially the area containing the dialysis material, is prone to collapse, deformation, or even breakage due to pressure. This not only affects the flatness of the bag's appearance, but more seriously, deformation can compress the internal space, causing the devices to move and rub against each other inside, generating debris or damaging the devices. Summary of the Invention

[0004] The purpose of this invention is to provide a medical packaging bag with reinforced bottom support. The ingenious structure can strengthen the support of the bottom of the bag, improve the overall stability, and is 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 includes a front film and a rear film. The rear film includes an upper film layer and a lower dialysis layer. The lower end of the upper film layer is heat-sealed with the upper end of the lower dialysis layer, and the lower dialysis layer is disposed on the outside of the upper film layer. The sides of the upper film layer and the sides of the lower dialysis layer are heat-sealed with the sides of the front film. The lower end of the lower dialysis layer is heat-sealed with the lower end of the front film. After the front and rear films are heat-sealed, a bag body with an open top is formed. The bag body is provided with a self-sealing tape that can close the opening. A support film layer is also provided between the front film and the lower dialysis layer. Each side of the support film layer is heat-sealed with the sides of the front film and the lower dialysis layer. The bottom edge of the support film layer is heat-sealed with the bottom edge of the front film and the lower dialysis layer. The top edge of the support film layer is heat-sealed onto the lower dialysis layer. The support film layer after the lower dialysis layer is heat-sealed and fixed together with the front film forms a support part that can support the items inside the bag.

[0006] Furthermore, both the front and rear films are heat-sealed with horizontally arranged plastic frame rods. These plastic frame rods are equipped with support components to support the expanded bag body. The support components include a connecting plate rotatably connected to the plastic frame rod, a lifting plate slidably connected to the connecting plate, and a rotating support plate movably connected between the lifting plate and the connecting plate. The connecting plate has a first lifting groove for the lifting plate to slide up and down, and a second lifting groove for the rotating support plate to rotate. The side of the second lifting groove has a side slot providing rotation space for the descending rotating support plate. The lower end of the lifting plate is rotatably connected to the rotating support plate via a connecting shaft. The connecting plate has an extension to the first lifting groove. A connecting shaft is slidably disposed within a parallel limiting waist groove. An inner push block is slidably disposed within the first lifting groove. The inner push block is disposed at the bottom of the lifting plate and the first lifting groove. Multiple compression springs are disposed between the inner push block and the bottom of the first lifting groove. The two ends of each compression spring are fixedly connected to the inner push block and the bottom of the first lifting groove, respectively. The inner push block is fixedly disposed at the upper end of the lifting plate. The lifting plate slides within the first lifting groove by continuously applying force to the inner push block through the compression springs, thereby driving the connecting shaft to slide within the limiting waist groove. A male buckle is disposed at the end of the connecting shaft away from the lifting plate. A female buckle that matches the male buckle is disposed on the bag body. The male buckle on the connecting shaft is connected to the female buckle on the bag body when the lifting plate and the rotating support plate are in the initial state.

[0007] Furthermore, the aforementioned connecting shaft is a plastic part, and the connecting shaft is fixedly mounted on the lifting plate. The rotating support plate is provided with a square rotating hole, and the connecting shaft is provided with a square rotating part corresponding to the square rotating hole. The rotating support plate is positioned after rotation through the cooperation of the square rotating hole and the square rotating part.

[0008] Furthermore, connecting shafts are provided on both sides of the aforementioned connecting shaft, and limiting arc blocks are provided on the connecting shafts and coaxially arranged with the connecting shafts. The limiting arc blocks are integrally formed with the connecting shafts. The plastic frame rod is provided with connecting rotating holes corresponding to each connecting shaft and limiting arc grooves corresponding to the limiting arc blocks. The arc length of the limiting arc groove is greater than the arc length of the limiting arc block. The plastic frame rod is slidably connected to the plastic frame rod through the rotational engagement of the connecting shafts and connecting rotating holes, and the limiting engagement of the limiting arc blocks and limiting sliding grooves.

[0009] Furthermore, anti-wear pads are provided between the lifting plate and the rotating support plate, as well as between the rotating support plate and the connecting plate.

[0010] Furthermore, the side panel of the bag body is provided with an easy-tear opening, and the bag body is also provided with a hanging opening for hanging the bag body. Both the easy-tear opening and the hanging opening are located above the self-sealing tape.

[0011] The present invention has the following positive effects: (1) The present invention adds an independent support membrane layer between the front membrane and the lower dialysis layer and heat-seales each side of the support membrane layer to form a rigid or semi-rigid support structure integrated inside the bag body. The support membrane layer provides additional mechanical strength to the bottom of the bag body, so that it can effectively resist deformation when bearing the weight of the internal instruments or external pressure, keep the bottom of the bag body flat, and avoid the problem of the bottom collapsing and squeezing the internal items. The support membrane layer shares most of the stress applied to the bottom of the bag body, reducing the risk of the lower dialysis layer being directly subjected to force and breaking or producing permanent wrinkles, thereby ensuring the integrity and reliability of its dialysis function. The support membrane layer is integrated with the bag body by heat sealing, without additional assembly steps, without changing the basic shape of the packaging bag and the usage process, and at the same time avoiding the risk of falling off or contamination that may be caused by using external support parts. In addition, the formed support part provides a stable placement platform for the instruments, reducing the shaking and friction of the instruments during transportation, which is beneficial to protecting precision instruments.

[0012] (2) This utility model uses a plastic frame rod to install the support assembly. Through the linkage of the connecting plate, lifting plate and rotating support plate in the support assembly, the bag body after being opened can be actively supported and fixed in an unfolded state, so that it can stand up like a box, which greatly facilitates the insertion and removal of instruments and frees the user's hands. The continuous force applied to the inner push block by the compression spring drives the lifting plate and connecting shaft to move, and finally achieves automatic locking through the cooperation of male and female buckles, realizing the rapid extension and support of the support structure. The rotating support plate and the connecting plate and lifting plate form a stable triangular or trapezoidal support structure. The cooperation of the limiting waist groove and the connecting shaft ensures the accuracy of the movement trajectory and prevents the parts from loosening or misaligning during the support process.

[0013] (3) By setting a square rotating part on the connecting shaft and a square rotating hole on the rotating support plate, and setting the square rotating part to a plastic material, this utility model can ensure that damped rotation is generated between the rotating support plate and the connecting shaft, and ensure that the rotating support plate can be effectively positioned when it rotates to a specific angle, especially the fully extended support angle, to prevent it from rotating unexpectedly under stress, thereby enhancing the stability of the support state. The connecting shaft is made of a plastic part and is fixedly connected to the lifting plate, so that the lifting plate, the connecting shaft and the rotating support plate form a more robust transmission whole that can withstand greater loads.

[0014] (4) By setting the combination of limiting arc block and limiting arc groove, this utility model can limit the rotation angle of the connecting plate on the one hand, and allow the connecting plate to rotate slightly and in a limited manner when subjected to an unexpected external force, thus playing a buffering role and effectively preventing structural damage to the support component due to violent operation or excessive load. By setting the arc length of the limiting arc groove, the rotation limit angle of the connecting plate is precisely controlled, which ensures that the support component has enough room to move smoothly to unfold and store, and avoids interference with other structures or tearing of the film material due to excessive rotation angle.

[0015] (5) By setting anti-wear pads, this utility model effectively prevents direct friction and wear between the lifting plate and the connecting plate, as well as between the rotating support plate and the connecting plate during relative movement, thus extending the service life of the support components. The anti-wear pads are usually made of low friction coefficient materials such as PTFE or nylon, which makes the unfolding and retraction of the support components smoother.

[0016] (6) By setting an easy-tear opening and a hanging opening, the present invention allows the packaging bag to be hung on a shelf or hook, saving storage and display space, while making the label information easier to view and improving the convenience of use. By setting the easy-tear opening and the hanging opening above the self-sealing tape, it is ensured that these functional structures will not affect the sealing performance of the self-sealing tape, while maintaining the simplicity of the bag structure.

The inner push block 27 is disposed at the bottom of the lifting plate 22 and the first lifting groove 211. Multiple compression springs 28 are disposed between the inner push block 27 and the bottom of the first lifting groove 211. The two ends of each compression spring 28 are fixedly connected to the inner push block 27 and the bottom of the first lifting groove 211, respectively. The inner push block 27 is fixedly disposed at the upper end of the lifting plate 22. The lifting plate 22 slides in the first lifting groove 211 by continuously applying force to the inner push block 27 through the compression springs 28, and drives the connecting shaft 24 to slide in the limiting waist groove 214. A male buckle 25 is disposed at one end of the connecting shaft 24 away from the lifting plate 22. A female buckle 19 that is adapted to the male buckle 25 is disposed on the bag body 1. The male buckle 25 on the connecting shaft 24 is connected to the female buckle 19 on the bag body 1 when the lifting plate 22 and the rotating support plate 23 are in the initial state.

[0020] The connecting shaft 24 is a plastic part and is fixedly mounted on the lifting plate 22. The rotating support plate 23 is provided with a square rotating hole 231, and the connecting shaft 24 is provided with a square rotating part 241 corresponding to the square rotating hole 231. The rotating support plate 23 is positioned after rotation through the cooperation of the square rotating hole 231 and the square rotating part 241.

[0021] The connecting shaft 24 has connecting rotating shafts 29 on both sides. The connecting rotating shaft 29 has a limiting arc block 291 coaxially arranged with the connecting rotating shaft 29. The limiting arc block 291 is integrally formed with the connecting rotating shaft 29.

The arc length of the limiting arc groove 182 is greater than the arc length of the limiting arc block 291. The plastic frame rod 18 is limited and slidably connected to the plastic frame rod 18 through the rotational cooperation between the connecting rotating shaft 29 and the connecting rotating hole 181, and the limiting cooperation between the limiting arc block 291 and the limiting groove.

[0022] Anti-wear pads 26 are provided between the lifting plate 22 and the rotating support plate 23, and between the rotating support plate 23 and the connecting plate 21. The anti-wear pads 26 are sleeved on the connecting shaft 24.

[0023] The side panel of the bag body 1 is provided with an easy-tear opening 16, and the bag body 1 is also provided with a hanging opening 17 for hanging the bag body 1. The easy-tear opening 16 and the hanging opening 17 are both located above the self-sealing tape 15.

[0024] The working principle of this utility model is as follows: During the initial packaging of medical supplies, the support film layer 14 enhances the support of the bottom of the bag body 1, effectively solving the problem of bottom collapse or damage in the prior art. Then, during use, the user tears open the top of the bag body 1 through the easy-tear opening 16, and then opens the self-sealing tape 15. After opening, the user can detach the male buckle 25 on the connecting shaft 24 from the female buckle 19 on the bag body 1. The connecting plate 21 rotates to a support angle through the cooperation of the connecting shaft 29 and the connecting rotating hole 181, and the cooperation of the limiting arc block 291 and the limiting arc groove 182. Then, the lifting plate 22 moves downward under the continuous force of the various compression springs 28, driving the rotating support plate 23 to move downward as well. After reaching the side slot 213, the 23 rotates and unfolds. During the rotation and unfolding process of the rotating support plate 23, the damping cooperation of the square rotating hole 231 and the square rotating part 241 can keep the rotating support plate 23 in a horizontal state after it rotates to a horizontal position, thereby ensuring the support of the bag body 1. After unfolding, the rotating support plates 23 on both sides can provide overall support for the bag body 1. After the support is completed, the user can first rotate the rotating support plate 23. After the rotation, the rotating support plate 23 is positioned after rotation through the cooperation of the square rotating hole 231 and the square rotating part 241. Then, the user inserts the lifting plate 22 and the rotating support plate 23 into the first lifting slot 211 and the second lifting slot 212 respectively to overcome the continuous force of the spring. After the lifting plate 22 and the rotating support plate 23 are reset, the connecting plate 21 is fixed on the bag body 1 through the cooperation of the male buckle 25 and the female buckle 19, thereby realizing the reset of the support component 2.
