Description

Technical Field

[0001] The utility model relates to the technical field of medical neck braces, and more particularly to a medical neck brace for promoting blood circulation in the neck. Background Art

[0002] In the existing technology, the design of medical cervical collars for promoting blood circulation in the neck often has some shortcomings. First, many existing cervical collars adopt a fixed structure, which means that the height of the support frame is preset and cannot be adjusted. This design limits the adaptability of the cervical collar, because different users may require support of different heights to obtain the best support effect. For those users with longer or shorter necks, this fixed structure may not provide sufficient support, thus affecting the user experience and treatment effect.

[0003] Secondly, in the existing technology, in order to connect the support frame and the back plate, it is usually necessary to use components such as flexible belts and buckles. This connection method may have some problems in actual operation. The connection between the flexible belt and the buckle may require a large force when disassembling, and sometimes even requires the use of tools, which increases the risk of violent disassembly and may cause damage to the equipment. Moreover, due to the cumbersome connection and disassembly process of connection methods other than buckles, these devices often cannot be quickly connected and disassembled, which is particularly inconvenient when the neck brace needs to be frequently adjusted or replaced.

[0004] In addition, although some devices have appeared in the prior art to achieve rapid fixation and release of flexible belts, the structures of these devices are usually simple and not very stable. After long-term use or under the influence of external factors (such as patient neck movement or impact, etc.), these connecting parts may become loose. What is more serious is that if the looseness is not discovered and handled in time, the connecting parts may even fall off, which will not only cause the neck brace to fail, but may also cause accidental injury to the user.

[0038] In this embodiment, when the flexible belt 39 needs to be fixed, first make one end of the quick-change rod 2 pass through the slot 38 provided on the flexible belt 39, then put the quick-change sleeve 3 on the outside of the quick-change rod 2, and make the quick-change block 8 provided on the outside of the quick-change rod 2 inserted into the adapter groove 25, and then continue to push the quick-change sleeve 3, the quick-change block 8 will slide out of the adapter groove 25 and enter the connecting groove 7, and then the adapter block 23 will enter the adapter groove 25, and then one side of the support block will press against one side of the matching sleeve 5, and then continue to push the quick-change sleeve 3, the quick-change rod 2 will squeeze the second push spring 34 through the push plate 35, and at the same time the quick-change rod 2 will drive the quick-change block 8 to pass through the connecting groove 7, and then the support block will push the matching sleeve 5 to slide inside the quick-change sleeve 3, and then the matching sleeve 5 will drive the guide plate 35 to press the second push spring 34 ... The guide groove 30 disengages from the outside of the guide rod 29, and the matching sleeve 5 squeezes the second spring 31 set on one side, and then the quick-change sleeve 3 is rotated, the quick-change rod 2 drives the quick-change block 8 to slide into the movable groove 4, and the quick-change rod 2 drives the matching sleeve 5 to rotate through the adapter block 23 and the adapter groove 25, so that the guide groove 30 and the guide rod 29 no longer correspond to each other, and then the matching sleeve 5 drives the elastic plate 9 set on the outside to rotate, and then the elastic plate 9 is squeezed by the limit block 26, so that the elastic plate 9 gathers inward and closes to the matching sleeve 5, and when one side of the quick-change block 8 is tightly attached to one side of the fixed block 24, the quick-change sleeve 3 is stopped from rotating, and then the elastic plate 9 is reset and tightly engaged with the corresponding limit block 26 side, and is limited by the slide rod 32 and the slide groove 33, and the limit sleeve 19 will not drive the limit The block 26 rotates, and due to the arrangement of the limit frame 10 and the limit plate 14, the limit sleeve 19 is stably supported to one side of the rotating plate 16, so that the limit sleeve 19 will not drive the limit block 26 to slide, thereby ensuring a fast and stable connection mechanism. When the flexible belt 39 needs to be removed, the rotating plate 16 is first rotated, and the rotating plate 16 drives the return block 18 to move, and then the limit rod 13 will penetrate into the limit groove 17 opened on the side wall of the return block 18. At the same time, the return block 18 will cooperate with the fixed block 24 to squeeze the first spring 12 sleeved on the outer side of the limit rod 13. When the first spring 12 is squeezed to the limit, the position of the limit plate 14 just corresponds to the position of the give way groove 15, and then pushes the limit sleeve 19, which drives the limit frame 1 0 and the limit plate 14 slide along the slide rod 32 and the slide groove 33, and then the limit plate 14 and the limit frame 10 will pass through the yield groove 15, and at the same time the limit sleeve 19 will cooperate with the rotating plate 16 to squeeze the first push spring 21. When the first push spring 21 is squeezed to the limit, the corresponding limit plate 14 just moves to the side of the rotating plate 16, and then the rotating plate 16 is released, the first spring 12 pushes the return block 18 and the rotating plate 16 to reset, and then the position of the yield groove 15 no longer corresponds to the limit plate 14, and then the limit sleeve 19 is released. The limit sleeve 19 will be hung on the side of the rotating plate 16 through the limit frame 10 and the corresponding limit plate 14, and the limit sleeve 19 will drive the limit block 26 set on the inside from the through groove 27 into the matching groove 22. At this time, the elastic plate 9 loses the limit of the limit block 26.Then, the quick-change sleeve 3 is rotated in the opposite direction, so that the quick-change sleeve 3 drives the fixed block 24 and the movable slot 4 to rotate. When the communicating slot 7 moves to the position corresponding to the quick-change block 8, the connecting sleeve 20 drives the guide rod 29 to move to the position corresponding to the guide slot 30. Then, the second push spring 34 pushes the quick-change sleeve 3 and the quick-change rod 2 to separate through the push plate 35. Then, the quick-change rod 2 will drive the quick-change block 8 to enter the communicating slot 7. Then, the quick-change sleeve 3 is pulled, and the quick-change rod 2 drives the adapter block 23 to disengage from the adapter slot 25, and the quick-change block 8 will enter the adapter slot 25. At this time, one side of the matching sleeve 5 loses the limit of the top block 28, and then the second spring 31 pushes the matching sleeve 5 to reset, so that the matching sleeve 5 is connected The guide groove 30 is sleeved on the outside of the guide rod 29, and then the quick-change sleeve 3 is continuously pulled to remove the quick-change sleeve 3 from the outside of the quick-change rod 2. The rotating plate 16 is then rotated again, causing the rotating plate 16 to drive the clearance groove 15 to move, and the return block 18 and the fixed block 24 to cooperate again to squeeze the first spring 12. When the clearance groove 15 moves to the position corresponding to the limit plate 14, the first push spring 21 pushes the limit sleeve 19 to drive the limit frame 10 and the limit plate 14 to return to their original position. The rotating plate 16 is then released, and the first spring 12 pushes the return block 18 and the rotating plate 16 to return to their original position, so that the limit sleeve 19 is once again stably engaged with the outside of the quick-change sleeve 3 through the limit frame 10 and the corresponding limit plate 14.

[0039] See also Figure 1-3 , as an implementation method of the adjustment device: the adjustment device includes a lifting frame 36, a back plate 37, a slot 38, a flexible belt 39, a telescopic rod 40 and a telescopic sleeve 41.

The knob 43 provided on one side of the back plate 37 is movably connected to the back plate 37 through a screw, and the knob 43 provided on one side of the telescopic sleeve 41 is movably connected to the telescopic sleeve 41 through a screw.

[0042] More specifically, when the height of the equipment needs to be adjusted, the knob 43 provided on one side of the telescopic sleeve 41 is turned, and the knob 43 drives the screw provided on one side to unscrew from the telescopic sleeve 41, so that one end of the screw provided on one side of the knob 43 no longer presses the side wall of the telescopic rod 40, and then pushes the lifting frame 36, and the lifting frame 36 drives the telescopic sleeve 41 to move along the telescopic rod 40. At the same time, the lifting frame 36 drives the corrugated sleeve 42 connected to the other end to expand or compress. After adjusting to the appropriate height, the knob 43 is turned in the opposite direction, so that the screw provided on one side of the knob 43 presses the telescopic rod 40 to the inside of the telescopic sleeve 41 again, thereby preventing the telescopic rod 40 and the telescopic sleeve 41 from moving. Then, the support frame 1 is placed in front of the patient, and then the backboard 37 is placed behind the patient. Then, the backboard 37 and the support frame 1 are connected together by the flexible belt 39, so that the lifting frame 36 and the backboard 37 cooperate to support the patient's head.

[0043] In summary, when the overall device is in use or running: when the flexible belt 39 needs to be fixed, first make one end of the quick-change rod 2 pass through the slot 38 opened on the flexible belt 39, then put the quick-change sleeve 3 on the outside of the quick-change rod 2, and make the quick-change block 8 provided on the outside of the quick-change rod 2 inserted into the adapter groove 25, and then continue to push the quick-change sleeve 3, the quick-change block 8 will slide out of the adapter groove 25 and enter the connecting groove 7, and then the adapter block 23 will enter the adapter groove 25, and then one side of the support block will press against one side of the matching sleeve 5, and then continue to push the quick-change sleeve 3, the quick-change rod 2 will squeeze the second push spring 34 through the push plate 35, and at the same time the quick-change rod 2 will drive the quick-change block 8 to pass through the connecting groove 7, and then the support block will push the matching sleeve 5 to slide inside the quick-change sleeve 3 , then the matching sleeve 5 will drive the guide groove 30 to disengage from the outside of the guide rod 29, and at the same time the matching sleeve 5 will squeeze the second spring 31 set on one side, and then the quick-change sleeve 3 will be rotated, the quick-change rod 2 will drive the quick-change block 8 to slide into the movable groove 4, and at the same time the quick-change rod 2 will drive the matching sleeve 5 to rotate through the adapter block 23 and the adapter groove 25, so that the guide groove 30 and the guide rod 29 no longer correspond to each other, and then the matching sleeve 5 drives the elastic plate 9 set on the outside to rotate, and then the elastic plate 9 is squeezed by the limit block 26, so that the elastic plate 9 gathers inward and close to the matching sleeve 5, and when one side of the quick-change block 8 is tightly attached to one side of the fixed block 24, the quick-change sleeve 3 is stopped from rotating, and then the elastic plate 9 is reset and tightly engaged with the corresponding limit block 26 side, and is pressed by the slide bar 32 and the slide groove 33 The limit sleeve 19 will not drive the limit block 26 to rotate. Due to the arrangement of the limit frame 10 and the limit plate 14, the limit sleeve 19 is stably supported to one side of the rotating plate 16, so that the limit sleeve 19 will not drive the limit block 26 to slide, thereby ensuring a fast and stable connection mechanism. When the flexible belt 39 needs to be removed, the rotating plate 16 is first rotated, and the rotating plate 16 drives the return block 18 to move, and then the limit rod 13 will penetrate into the limit groove 17 opened on the side wall of the return block 18. At the same time, the return block 18 will cooperate with the fixed block 24 to squeeze the first spring 12 sleeved on the outside of the limit rod 13.

[0044] When the height of the equipment needs to be adjusted, the knob 43 provided on one side of the telescopic sleeve 41 is turned, and the knob 43 drives the screw provided on one side to unscrew from the telescopic sleeve 41, so that one end of the screw provided on one side of the knob 43 no longer presses the side wall of the telescopic rod 40, and then pushes the lifting frame 36, and the lifting frame 36 drives the telescopic sleeve 41 to move along the telescopic rod 40. At the same time, the lifting frame 36 drives the corrugated sleeve 42 connected to the other end to expand or compress. After adjusting to the appropriate height, the knob 43 is turned in the opposite direction, so that the screw provided on one side of the knob 43 presses the telescopic rod 40 to the inside of the telescopic sleeve 41 again, thereby preventing the telescopic rod 40 and the telescopic sleeve 41 from moving. Then, the support frame 1 is placed in front of the patient, and the backboard 37 is placed behind the patient. Then, the backboard 37 and the support frame 1 are connected together by the flexible belt 39, so that the lifting frame 36 and the backboard 37 cooperate to support the patient's head.

[0045] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the attached claims and their equivalents.
