DETAILED DESCRIPTION
[0018] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.
[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a disposable packaging bag for penis injection test includes: a packaging bag body 11 is a disposable plastic hard structure, used to contain various tools required for penis injection test; The disposable plastic hard structure ensures hygiene and sterility during use to avoid cross infection. The accordion-like folding design is easy to store and unfold. It also has good sealing and elasticity, and can automatically close the bag mouth to ensure that the tool remains sterile before use. A pusher mechanism 2 is provided inside the packaging bag body 11, which is used to push the hand-pinched position of the penis injection tool out of the packaging bag body 11. The pusher mechanism 2 includes a plurality of liner bags 21 and a plurality of lifting members 22. Each lifting member 22 corresponds to one liner bag 21. The lifting member 22 includes an elastic pull tab 23 and a release member. The release member is connected to the bottom of the lifting member 22, and the release member includes two leaf drawing wires 44. Each tool is placed separately in the liner bag 21 to avoid collision and cross contamination between tools, and to facilitate classification management. Through the linkage mechanism of the elastic pull tab 23 and the release member, the tool can be automatically pushed out of the packaging bag body 11, so that the hand-holding position of the tool is exposed, which is convenient for medical staff to quickly take it out. The elastic contraction force is provided to automatically push the tool out of the packaging bag body 11, and the tool can be retracted when needed to ensure that the tool remains in the packaging bag body 11 when not in use; The side wall of the packaging bag body 11 is provided with a bag fixing mechanism 3, which is used to pull open and fix the packaging bag body 11. The bag fixing mechanism 3 includes two side swing leaves 31. When the two side swing leaves 31 are opened, they are used to support the packaging bag body 11 to stand on the doctor's workbench; The leaf drawing wire 44 is connected to the side swing leaf 31. By opening the two side swing leaves 31, the leaf drawing wire 44 is pulled to make the release piece release the downward pulling force on the liner bag 21. Through the elastic contraction of the elastic pull tab 23, various tools for penis injection are pushed out of the packaging bag body 11.
[0020] An elastic sealing ring is provided at the bag opening of the packaging bag body 11. The elastic sealing ring is made of flexible elastic material and can automatically close to maintain the sealing of the packaging bag body 11, prevent external contamination from entering the interior of the packaging bag body 11, and ensure that the internal tools remain sterile before use. The bag opening is elastic and can automatically close to prevent external contamination from entering the interior of the packaging bag body 11, further ensuring a sterile environment.
[0021] The side swing leaves 31 of the bag fixing mechanism 3 are connected to the side walls of the packaging bag body 11 through a fold, and the fold is located at the connection between the side swing leaves 31 and the packaging bag body 11, so that the side swing leaves 31 can expand outward along the fold to form a supporting structure, so that the packaging bag body 11 can stand stably on the workbench.
[0022] like Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, the bottom end of the elastic pull tab 23 of the lifting member 22 is fixedly connected to the bottom plate 26, and the other end is fixedly connected to the inner wall of the liner bag 21. The lower wall of the bottom plate 26 is connected to the follower column 401 through the pull seat rope 402. The follower column 401 is located in the inner cavity 41. The pull seat rope 402 passes through the rope hole 46 on the limit plate 42 and is connected to the elastic rope 48 through the force ball 47. The opening action of the side swing leaf 31 pulls the leaf drawing wire 44, releasing the downward pulling force on the liner bag 21, thereby realizing the automatic pushing out of the tool.
[0023] Through the resilience of the elastic rope 48, the tool can be quickly retracted into the packaging bag when the side swing leaf 31 is closed to prevent the tool from being exposed outside.
[0024] The contraction force of the elastic pull tab 23 drives the follower column 401 to rise, thereby pushing the tool out of the packaging bag body 11, thereby realizing quick access to the tool.
[0025] The bag fixing mechanism 3 also includes an adhesive plate 32, and an adhesive layer 33 is provided on the lower wall of the adhesive plate 32. The adhesive layer 33 can adhere to the workbench after the protective film is torn off, so as to further fix the position of the packaging bag body 11 and prevent displacement during use.
[0026] The inner wall of the liner bag 21 is provided with a sheet fixing glue area 24, which is used to adhere the elastic side wall sheet 25. The elastic side wall sheet 25 is connected to the elastic pull tab 23 to form a protective structure for fixing and protecting the tools in the liner bag 21 to prevent the tools from colliding or being damaged during the movement of the packaging bag body 11.
[0027] A tip guard hole 27 is provided on the bottom plate 26. The tip guard hole 27 is used to insert a pointed tool to prevent the pointed tool from damaging the packaging bag body 11 or scratching other tools when moving in the packaging bag body 11. The shape of the tip guard hole 27 matches the shape of the pointed tool to ensure that the tool can be stably inserted therein to protect the tool from collision, especially the pointed tool. The pointed part is further fixed by the tip guard hole 27 to prevent damage to the packaging bag body 11 or other tools.
[0028] A magnetic base 12 is provided at the bottom of the packaging bag body 11, and the magnetic base 12 is used to adsorb on the workbench to further enhance the stability of the packaging bag body 11 and prevent it from tipping over due to external force during use. The adsorption force of the magnetic base 12 is adjusted according to the weight and size of the packaging bag body 11 to ensure that it can be stably adsorbed on the metal workbench. A magnetic base 12 is provided at the bottom, which can be adsorbed on the metal workbench to enhance the stability of the packaging bag body 11 and prevent it from tipping over due to external force during use.
[0029] A closing wire 35 is provided between the side swing leaf 31 and the outer wall of the packaging bag body 11. One end of the closing wire 35 is connected to the inner side of the side swing leaf 31, and the other end is connected to the outer wall of the packaging bag body 11. When the side swing leaf 31 is pulled open, the closing wire 35 can provide a certain resilience to prevent the side swing leaf 31 from over-expanding. At the same time, when the side swing leaf 31 is separated from the outer wall of the packaging bag body 11, the closing wire 35 can quickly pull the side swing leaf 31 back to ensure the sealing of the packaging bag body 11. By opening the side swing leaf 31 , the packaging bag body 11 can be quickly opened and made to stand on a workbench for easy operation.
[0030] The adhesive plate 32 is fixed on the workbench through the adhesive layer 33, which further enhances the stability of the packaging bag body 11 and prevents displacement during use.
[0031] When the side swing leaf 31 is separated from the outer wall of the packaging bag body 11, a rebound force is provided to ensure that the packaging bag body 11 can quickly restore the sealing state to prevent contamination.
[0032] A support plate seat 43 is provided in the inner chamber 41 inside the packaging bag body 11. The support plate seat 43 is used to support the limiting plate 42. The two ends of the limiting plate 42 are respectively fixed to the bottom wall of the inner chamber 41 through the support plate seat 43. The following leaf drawing wire 44 passes through the thread opening 45 on the support plate seat 43 and is connected to the elastic rope 48 through the force-bearing ball 47. The other end of the elastic rope 48 is fixed to the support plate seat 43. Before medical staff treat patients, they need to sterilize all tools they need to use and put them into the packaging bag body 11 in advance, such as tweezers, scissors, syringes and other tools. Each tool is placed in the inner liner bag 21 separately. Because the structure of the packaging bag body 11 is similar to an accordion, and the bag opening of the packaging bag body 11 is elastic, the bag opening can be automatically closed after various tools are placed in. In addition, the material of the packaging bag body 11 should have good sealing and biocompatibility, ensuring that the tools are kept sterile before use. When the patient and the medical staff are all ready, the medical staff only needs to put the prepared packaging bag body 11 on the workbench, and then the nurse opens the side swing leaves 31 to separate the side swing leaves 31 on both sides from the sticky leaf tape 34 applied on the outer wall of the packaging bag body 11. To open the side swing leaves 31, the nurse needs to pinch the sticky plate 32 under the side swing leaves 31 with both hands at the same time and pull it outwards until the packaging bag body 11 is completely opened; There is a fold at the connection between the adhesive plate 32 and the side swing leaf 31. After the packaging bag body 11 is fully opened, the medical staff needs to tear off the film on the lower wall of the adhesive plate 32 to make the adhesive layer 33 leak out, and finally stick the two adhesive plates 32 to the surface of the workbench through the adhesive layer 33 to ensure that the entire packaging bag body 11 is in an open state. In addition, a magnetic seat 12 is also provided at the bottom of the packaging bag body 11, which is just adsorbed on the workbench to ensure the stability of the packaging bag body 11. The bottom of the plurality of lifting members 22 has an inner chamber 41, the entire release member is fixed in the inner chamber 41, the release member also includes a limiting plate 42, the two ends of the lower wall of the limiting plate 42 are respectively fixed to the bottom wall of the inner chamber 41 through a support plate seat 43, the leaf drawing wire 44 passes through the thread opening 45 opened in the support plate seat 43, a force-bearing ball 47 is fixed at the other end of the leaf drawing wire 44, and an elastic rope 48 fixed to another support plate seat 43 is arranged on the other side of the force-bearing ball 47, and a column rope 49 is also arranged on the side wall of the force-bearing ball 47, and the leaf drawing wires 44 on both sides and the equipment connected to them are symmetrical with each other. When the following leaf drawing wire 44 is pulled by the side swing leaf 31 to open, the following leaf drawing wire 44 pulls the force-bearing ball 47 to move through the rope hole 46 toward the center of the limiting plate 42, thereby loosening the column rope 49. At the same time, the two elastic pull tabs 23 of the lifting member 22 retract elastically and pull the bottom seat rope 402. The seat rope 402 pulls the following column 401 upward, thereby indirectly releasing the downward pull on the lifting member 22, causing the two elastic pull tabs 23 to retract, driving the bottom plate 26 to move upward, and pushing various tools inserted in the lifting member 22 out of a part of the bag opening of the packaging bag body 11, just enough to make the tools leak out of the position where they are pinched by hand. The side walls of the two elastic pull tabs 23 are also provided with elastic side wall sheets 25, which are adhered to the inner wall of the liner bag 21 through the sheet fixing adhesive area 24 on the outer wall of the elastic side wall sheet 25, so as to protect various tools. If the tool is a pointed tool, the pointed tool can be inserted into the tip protection hole 27 in the bottom plate 26 to protect the pointed tool. If any of the adhesive plates 32 suddenly leaves the workbench, the side swing leaf 31 will quickly merge with the outer wall of the packaging bag body 11 under the strong rebound force of the multiple drawing wires 35 between the side swing leaf 31 and the outer wall of the packaging bag body 11. At this time, the force ball 47 loses the pulling force of the follower wire 44. Under the rebound force of the elastic rope 48, the force ball 47 moves toward the end away from the rope hole 46, thereby pulling the pull column rope 49, and the follower column 401 is pulled down by the pull column rope 49. The follower column 401 simultaneously pulls down multiple pull seat ropes 402, thereby indirectly retracting various unused tools back into the packaging bag body 11; Because the bag mouth of the packaging bag body 11 is elastic, it will rebound after the tension of the adhesive plate 32, and the other side still has tension, so the packaging bag body 11 will tilt to the side with tension, and indirectly; the leaf drawing wire 44 on the other side will also relax; The various mechanisms in the packaging bag body 11 are all made of plastic and connected by ropes, which are low in cost and suitable for disposable use.
[0033] The combination of disposable design and accordion-like structure provides an efficient, hygienic and easy-to-operate packaging solution, significantly improving the convenience and safety of medical device packaging; The design of the push mechanism 2 realizes the automatic pushing out and retracting of the tool, greatly improving the operating efficiency of medical staff, while protecting the integrity of the tool and reducing the risks during operation. The design of the bag fixing mechanism 3 not only improves the stability of the packaging bag body 11, but also realizes rapid unfolding and sealing recovery through the linkage mechanism of the side swing leaves 31, which significantly improves the convenience and safety of operation.
[0034] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
