Description

Technical Field

[0001] This utility model relates to the field of maternity pack technology, and more specifically, to a sterile maternity pack. Background Technology

[0002] In existing sterile maternity pack technology, the inability to achieve a two-way opening is a significant design flaw. In medical environments, especially in special places such as operating rooms or delivery rooms, medical staff often need to quickly retrieve medical supplies from different locations. The one-way opening design forces medical staff to walk around to a specific side of the pack to open and retrieve items. This not only increases operation time but may also cause inconvenience in retrieving items due to space constraints. In emergency situations, this design limitation may delay treatment time and affect medical outcomes. In addition, the one-way opening also increases the workload of medical staff, especially when items need to be retrieved frequently, as repeated walking around can cause unnecessary physical exertion.

[0003] The inconvenience of adjusting the handle position and the difficulty of installation and disassembly severely affect the practicality of maternity bags. Current technology often uses fixed handles that cannot be adjusted according to the user's height or usage habits. This inflexible design may lead to improper posture during transport, increasing the physical burden on medical staff. Furthermore, the installation and disassembly of handles are complex, requiring tools or considerable time, which not only increases maintenance costs but may also affect the convenience of daily use. When handle replacement or repair is needed, the complex disassembly and assembly process may render the maternity bag temporarily unusable, disrupting normal medical operations.

[0029] Please see Figures 1-5A sterile maternity bag includes a maternity bag 1, a two-way opening mechanism, a handle latching mechanism, and a latching auxiliary mechanism. The two-way opening mechanism includes a hinge frame 2, a rotating door 3, an observation window 4, a handle 5, and a side panel 6. One end of the rotating door 3 is rotatably mounted on one side of the maternity bag 1, and the maternity bag 1 has two-way openings, both of which are connected to the rotating door 3. The observation window 4 is installed on the rotating door 3. The side panels 6 are symmetrically installed on the top of the maternity bag 1. The handle 5 is installed on the top of the maternity bag 1 and the side panel 6. The connecting mechanism includes a snap-fit ​​tube 7, a snap-fit ​​rod 8, an inner push ring 9, a rubber ring 10, a slope rail 11, a moving block 12, and a compression spring frame 13. The snap-fit ​​rod 8 can extend into the interior of the snap-fit ​​tube 7, and the slope rail 11 is installed on the inner wall of the snap-fit ​​tube 7. The moving block 12 is slidably installed on the slope rail 11. The compression spring frame 13 is installed on the side of the moving block 12 and can press against the side wall of the snap-fit ​​rod 8. The inner push ring 9 is slidably installed on the inner wall of the snap-fit ​​tube 7, and the top end of the inner push ring 9 is slidably connected to the moving block 12.

[0030] In this embodiment, the bidirectional opening mechanism realizes the bidirectional opening function of the rotating door 3 through the hinge frame 2. The rotating door 3 is installed on one side of the maternity bag 1 and can be opened from two directions, making it convenient for medical staff to take out items from different positions. The setting of the observation window 4 allows the internal items to be viewed without opening the bag, reducing unnecessary opening times and maintaining a sterile internal environment. The design of the side panel 6 and handle 5 provides convenience for opening and carrying, making the operation of the entire bag more user-friendly. The position of the handle 5 can be adjusted, and the handle 5 can be installed on both sides and the top of the bag for easy operation by different people. When the handle 5 needs to be fixed, the locking rod 8 extends into the locking tube 7, the inner push ring 9 pushes the moving block 12 to slide on the slope rail 11, the compression spring frame 13 presses against the side wall of the locking rod 8, and the rubber ring 10 provides additional friction to increase the stability of the locking. This design ensures the stability of the handle 5 during use and also facilitates quick release when needed.

[0031] The snap-fit ​​auxiliary mechanism includes a rotating tube 14, a threaded outer ring 15, a rotating block 16, a throttle 17, spring-loaded pins 18, and mating holes 19. The rotating tube 14 is rotatably mounted on the outer wall of the snap-fit ​​tube 7. The threaded outer ring 15 is slidably mounted on the outer wall of the snap-fit ​​tube 7. The inner wall of the rotating tube 14 is threadedly connected to the outer wall of the threaded outer ring 15. The threaded outer ring 15 is connected to the inner push ring 9. The rotating block 16 is mounted at the bottom end of the rotating tube 14. Multiple sets of spring-loaded pins 18 are slidably mounted laterally on the outer wall of the snap-fit ​​tube 7. The throttle 17 is mounted at the outer end of the rotating block 16. Rotating the throttle 17 causes the rotating block 16 to rotate. One end of each spring-loaded pin 18 extends into the mating hole 19 on the rotating block 16, making the rotating tube 14 rotate stably.

[0032] In this embodiment, the operator turns the handle 17, causing the rotating block 16 to rotate. The rotation of the rotating block 16 causes the rotating tube 14 to rotate. Since the rotating tube 14 is threadedly connected to the threaded outer ring 15, the threaded outer ring 15 slides in a specific direction. The threaded outer ring 15 drives the inner push ring 9 to move through the connecting rod 25. The spring pin 18 extends into the mating hole 19 on the rotating block 16 step by step to ensure the stability and accuracy of the rotation process.

[0033] Please see Figures 1-5 As a supplementary embodiment of the sterile delivery bag for the two-way door opening mechanism, handle locking mechanism and locking auxiliary mechanism: the side plate 6 and the top end of the delivery bag 1 are provided with mounting holes 20, and the locking tube 7 is fixedly installed in the mounting holes 20. One end of the locking rod 8 is provided with a connecting plate 21. Both ends of the handle are rotatably provided with connecting seats 22, and the connecting seats 22 are connected to the connecting plate 21. The outer wall of the locking tube 7 is provided with a limiting rail 23, and the rotating tube 14 is rotatably installed on the limiting rail 23. One end of the compression spring frame 13 is provided with an embedded nail 24, and one end of the embedded nail 24 can extend into the rubber ring 10, so that the compression spring frame 13 presses the locking rod 8. The inner side of the threaded outer ring 15 is provided with a connecting rod 25, and the other end of the connecting rod 25 is connected to the outer end of the inner push ring 9. The side wall of the locking tube 7 is provided with a directional groove 26, and the connecting rod 25 is directionally slidably set in the directional groove 26.

[0034] More specifically, confirm that the delivery bag 1 is closed, the handle 5 is in the correct position, the locking mechanism is in place, and the rotating door 3 can be opened from either direction via the two-way opening mechanism. The observation window 4 allows for previewing the position of the items inside. The handle 5 provides a stable gripping point. When the position of the handle 5 needs to be adjusted, operate the locking auxiliary mechanism and turn the handle 17 to activate the entire adjustment system. Precise adjustment is achieved through threaded transmission. The locking rod 8 enters the locking tube 7, and the compression spring frame 13 and rubber ring 10 provide stable fixing force. Multiple mechanisms work together to ensure that the handle 5 is locked in position. The two-way opening can select the opening direction as needed. The handle 5 remains stable for easy handling, and the observation window 4 allows for easy viewing of the internal situation at any time.

[0035] In summary, when the overall equipment is in use or operation: when the bidirectional door opening mechanism is required, the bidirectional door opening mechanism realizes the bidirectional opening function of the rotating door 3 through the hinge frame 2. The rotating door 3 is installed on one side of the delivery bag 1 and can be opened from two directions, making it convenient for medical staff to take out items from different positions. The setting of the observation window 4 allows the internal items to be viewed without opening the bag, reducing unnecessary opening times and maintaining a sterile internal environment. The design of the side panel 6 and handle 5 provides convenience for opening and handling, making the operation of the entire bag more user-friendly.

[0036] When the handle latching mechanism is in operation, the position of the handle 5 can be adjusted. The handle 5 can be installed on both sides and the top of the box for easy operation by different people. When the handle 5 needs to be fixed, the latching rod 8 extends into the latching tube 7, the inner push ring 9 pushes the moving block 12 to slide on the slope rail 11, the compression spring frame 13 presses against the side wall of the latching rod 8, and the rubber ring 10 provides additional friction to increase the stability of the latching. This design ensures the stability of the handle 5 during use and also facilitates quick release when needed.

[0037] When the auxiliary mechanism needs to be engaged, the operator turns the handle 17, which drives the rotating block 16 to rotate. The rotation of the rotating block 16 drives the rotating tube 14 to rotate. Since the rotating tube 14 is threadedly connected to the threaded outer ring 15, the threaded outer ring 15 slides in a directional manner. The threaded outer ring 15 drives the inner push ring 9 to move through the connecting rod 25. The spring pin 18 extends into the mating hole 19 on the rotating block 16 step by step to ensure the stability and accuracy of the rotation process.

[0038] Confirm that the delivery bag 1 is closed, the handle 5 is in the correct position, and the locking mechanism is in place. The rotating door 3 can be opened from either direction via the two-way opening mechanism. The observation window 4 allows for previewing the position of the items inside. The handle 5 provides a stable gripping point. When the position of the handle 5 needs to be adjusted, operate the locking auxiliary mechanism and turn the handle 17 to activate the entire adjustment system. Precise adjustment is achieved through threaded transmission. The locking rod 8 enters the locking tube 7. The compression spring frame 13 and the rubber ring 10 provide stable fixing force. Multiple mechanisms work together to ensure that the handle 5 is locked in place. The two-way opening allows you to select the opening direction as needed. The handle 5 remains stable for easy handling, and the observation window 4 allows you to check the internal situation at any time.
