Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a multifunctional medical rapid emergency traction device. Background Technology

[0002] Limb fractures are a major type of injury in pre-hospital trauma caused by traffic accidents, falls from heights, and explosions. Improper on-site treatment can lead to secondary injuries, worsening the condition or even death. Therefore, in the pre-hospital emergency care for accidental injuries, as long as the environment is safe, appropriate protection should be provided for any factors involving changes in speed that could cause injury, regardless of whether the injured person complains of it, to prevent the patient from moving and causing secondary injuries.

[0003] In current emergency procedures, patients with severe limb fractures are typically secured to a stretcher using straps, gauze, or other ropes during transport to prevent vibrations from worsening their injuries. However, existing stretchers do not have the function of individually securing limbs; instead, straps are usually used to secure the patient's torso and limbs together. This method of fixation, because the patient's torso is higher than their limbs, especially the arms, and cannot accurately fix both ends of the fracture site, can lead to displacement of the fracture surface, exacerbating the patient's pain and damaging the bones, blood vessels, and nerve tissue at the injury site, thus affecting the later rehabilitation outcome.

[0013] Preferably, a positioning ring is embedded and fixedly connected to the outer wall of the outer half-ring, and the adjusting screw passes through the positioning ring and is rotatably connected to the positioning ring.

[0014] Preferably, the inner wall of the inner contact block is provided with a connecting groove, a contact layer is slidably connected in the connecting groove, a contact spring is fixed between the contact layer and the connecting groove, and a plurality of pressure sensors corresponding to the contact spring are fixedly connected to the bottom end of the connecting groove, with the end of the contact spring abutting against the pressure sensor.

[0015] Preferably, the support rod includes two corresponding support cylinders; an extension rod is slidably connected between the two support cylinders; a locking cylinder is provided between the extension rod and the support cylinders; and the end of the support cylinder away from the extension rod is limitedly connected to the outer half-ring through a locking assembly.

[0016] Preferably, the locking assembly includes a locking knob rotatably connected to the top of the support cylinder, and a locking cam coaxially arranged with the support cylinder is drivenly connected to the bottom end of the locking knob; a plurality of locking rods are slidably connected to the top of the support cylinder, and the locking rods abut against the outer wall of the locking cam; a plurality of locking holes adapted to the locking rods are provided on the outer half ring, and the locking rods are detachably connected in the locking holes.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0035] Reference Figure 1-8 As shown, this embodiment provides a multifunctional medical rapid emergency traction device, including two parallel outer rings 1, with a number of equally spaced support rods 2 fixed between the two outer rings 1; an inner ring 3 is movably connected inside the outer rings 1, and an ice pack 4 is fixedly connected and communicated between the two inner rings 3.

[0036] The outer ring 1 is divided into two detachably connected outer half-rings 5, and several support rods 2 are connected between the two corresponding outer half-rings 5.

[0037] The inner ring 3 includes several detachably connected inner contact blocks 6, and at least two inner contact blocks 6 are movably connected to the inner wall of any outer half ring 5. An adjustment component is fixedly connected between the inner contact blocks 6 and the outer half ring 5.

[0038] At least two ice packs 4 are provided and distributed at equal intervals. Both ends of any ice pack 4 are fixedly connected to and communicate with at least one inner contact block 6.

[0039] This invention belongs to the field of medical device technology. In use, the support rod 2 is adjusted to an appropriate length so that the two outer rings 1 are positioned on either side of the limb fracture area. Then, the inner ring 3 is fitted onto the patient's limb for fixation, preventing relative displacement of the fracture site and reducing bone loss caused by friction between fracture surfaces. This facilitates subsequent rehabilitation and avoids irritation of muscles, blood vessels, and nerve tissue by the broken bone, reducing patient pain and minimizing damage to nerves, blood vessels, and muscle tissue caused by the fracture, thus reducing post-rehabilitation sequelae. The outer ring 1 is designed as two detachable semi-rings for easy fitting onto the patient's limb, while the inner ring 3 is divided into several inner contact blocks 6 to accommodate different limb positions and shapes. The distance between the inner contact blocks 6 and the outer semi-rings 5 ​​can be adjusted using an adjustment component, improving the device's applicability to different limbs and areas. The ice pack 4 between the two inner semi-rings provides ice packs for pain relief after limb fixation, preventing the patient from moving in pain and aggravating the injury. This also improves patient comfort during transport and reduces swelling in the fracture area, facilitating subsequent bone setting and treatment.

[0040] This invention has a simple structure and is easy to use. It is suitable for injured people of different body types. When transporting patients with limb fractures for emergency treatment, it can effectively fix the fractured limbs, reduce the aggravation of the injury caused by limb movement, reduce the patient's pain, accelerate the patient's recovery efficiency, and improve the later recovery effect.

[0041] Further optimization of the scheme: the adjustment component includes an adjustment rod 7 and at least two guide rods 8 symmetrically arranged about the adjustment rod 7, with the guide rods 8 distributed along the direction of the support rod 2; one end of the adjustment rod 7 is fixedly connected to the outer wall of the inner contact block 6, and both ends of the adjustment rod 7 pass through the outer semi-ring 5; one end of the guide rod 8 is fixedly connected to the outer wall of the inner contact block 6, and the other end of the guide rod 8 is fixedly connected to the inner wall of the outer semi-ring 5. The adjustment component is used to adjust the distance between the inner contact block 6 and the outer semi-ring 5, thereby achieving fixation for different injured persons; the guide rods 8 are used to ensure the stability of the movement of the inner contact block 6 during adjustment, preventing the impact on the patient's injury caused by deviation, while the adjustment rod 7 serves as the power source for adjustment, driving the movement of the inner contact block 6.

[0042] Further optimization of the design: the guide rod 8 includes guide cylinders 9 fixedly connected to the outer half-ring 5 and the inner contact block 6 respectively. A movable rod 10 is slidably connected between the two guide cylinders 9, and a guide spring 11 is fixedly connected between the end of the movable rod 10 and the bottom end of the inner cavity of the guide cylinder 9. The two guide cylinders 9 are arranged correspondingly, and the movable rod 10 controls the displacement of the two guide cylinders 9 when the inner contact block 6 moves away from the outer half-ring 5. The guide spring 11 ensures the sliding between the movable rod 10 and the guide cylinder 9, and the spring that returns to its original position also provides force, making the moving-away process smoother. When the inner contact block 6 moves closer to the outer half-ring 5, the guide spring 11 is compressed, which also plays a stabilizing role.

[0043] Further optimizing the design, the adjusting rod 7 includes an adjusting cylinder 12 fixed to the outer wall of the inner contact block 6. The adjusting cylinder 12 is detachably connected to a clearance groove 13 formed on the inner wall of the outer half-ring 5. An adjusting screw 14 is threadedly connected to the end of the adjusting cylinder 12 away from the inner contact block 6. The adjusting screw 14 extends out of the outer half-ring 5 and is fixedly connected to an adjusting knob 15. A positioning ring 16 is embedded and fixedly connected to the outer wall of the outer half-ring 5. The adjusting screw 14 passes through the positioning ring 16 and is rotatably connected to the positioning ring 16. The adjusting screw 14 is rotatably connected to the outer half-ring 5 through the positioning ring 16. When the adjusting screw 14 rotates, its positional relationship with the adjusting cylinder 12 changes, causing the inner contact block 6 to move. The guide rod 8 ensures that the inner contact block can only translate and will not deflect.

[0044] To further optimize the design, a connecting groove 17 is formed on the inner wall of the inner contact block 6. A contact layer 18 is slidably connected within the connecting groove 17. A contact spring 19 is fixedly connected between the contact layer 18 and the connecting groove 17. Several pressure sensors 20, corresponding to the contact springs 19, are fixedly connected to the bottom end of the connecting groove 17. The ends of the contact springs 19 abut against the pressure sensors 20. The contact layer 18 is made of a flexible, skin-friendly material, improving comfort when in contact with the injured person's skin and reducing their pain. At the same time, the pressure sensors 20 can measure the contact pressure between the contact layer 18 and the patient's limb, facilitating control and preventing the patient from being unable to determine the fixation pressure due to pain. Too little pressure will not provide a secure fixation, while too much pressure will restrict blood flow. Therefore, the pressure sensors 20 allow for intuitive and quantitative control of the fixation degree.

[0045] Further optimization of the design: the support rod 2 includes two corresponding support cylinders 21; an extension rod 22 is slidably connected between the two support cylinders 21; a locking cylinder 23 is provided between the extension rod 22 and the support cylinders 21; the end of the support cylinder 21 away from the extension rod 22 is limitedly connected to the outer half-ring 5 through a locking assembly. The two support cylinders 21 are extended in length through the extension rod 22, so that the two outer half-rings 5 ​​are located on both sides of the injury site, which is suitable for different types of limb fractures; the locking cylinder 23 is used to fix the support cylinder 21 and the extension rod 22 after adjustment.

[0046] Further optimization of the scheme: the locking assembly includes a locking knob 24 rotatably connected to the top of the support cylinder 21, and a locking cam 25 coaxially arranged with the support cylinder 21 at the bottom of the locking knob 24; a number of locking rods 26 are slidably connected to the top of the support cylinder 21, and the locking rods 26 abut against the outer wall of the locking cam 25; a number of locking holes 27 adapted to the locking rods 26 are provided on the outer half ring 5, and the locking rods 26 are detachably connected in the locking holes 27. The locking assembly is used to fix the outer half-ring 5 and the support cylinder 21, facilitating adjustment and subsequent maintenance and replacement. In use, the outer half-ring 5 is placed at one end of the support cylinder 21, and then the locking knob 24 is rotated to rotate the locking cam 25. Finally, the locking rod 26 is aligned with the long axis of the locking cam 25, and the locking rod 26 is locked into the locking groove to achieve locking. After use, the locking knob 24 is reversed so that the short axis of the locking cam 25 is aligned with the locking rod 26, and the locking rod 26 is pulled out from the locking hole 27 to achieve unlocking.

[0047] In a further optimized design, the top of the support cylinder 21 has a reset groove 28 that matches the locking rod 26. The bottom end of the locking rod 26 is fixedly connected to a connecting block 29 that matches the reset groove 28. The connecting block 29 is slidably connected within the reset groove 28, and a reset spring 30 is fixedly connected between the connecting block 29 and the reset groove 28. When unlocking, the short shaft of the locking cam 25 aligns with the locking rod 26, and the reset spring 30, through the connecting block 29, drives the locking rod 26 to exit from the locking hole 27 to unlock.

[0048] In a further optimized design, several longitudinally arranged fixing blocks 31 are fixed to the outer wall of the outer half-ring 5, with the fixing blocks 31 corresponding to the support cylinder 21. A longitudinally arranged guide groove 32 is formed between the outer wall of the outer half-ring 5 and the inner wall of the fixing blocks 31, and the support cylinder 21 is adapted to and slidably connected to the guide groove 32. The fixing blocks 31 clamp the support cylinder 21 onto the outer half-ring 5, and can slide relative to it when there is no locking component.

[0049] Example 2

[0050] See attached document Figure 9-10 The difference between this embodiment and embodiment one is that the ice pack 4 in this embodiment includes two corresponding connecting plates 36, and the two connecting plates 36 are fixedly connected and connected to a retractable bag body 37; a first plug 38 and a second plug 39 are respectively provided on the two connecting plates 36. The first plug 38 is inserted into the first slot 40 on the corresponding inner contact block 6, and the second plug 39 is inserted into the second slot 41 on the corresponding inner contact block 6, thereby making the inner cavity of the bag body 37 connected to the water guiding cavity 35 in the inner contact block 6.

[0051] Each inner contact block 6 of the chain connected to the ice pack 4 is provided with a first connection port 33 and a second connection port 34 that communicate with the water guiding cavity 35, for the recycling of the ice pack material.

[0052] A connection hole 42 is provided on the side of the inner contact block 6 corresponding to the connecting plate 36; a connector 47 corresponding to the connection hole 42 is fixedly connected to the connecting plate 36. The connector 47 is inserted and fixed in the connection hole 42, so as to realize the quick disassembly of the connecting plate 36 and the inner contact block 6, and facilitate cleaning and disinfection after use.

[0053] The inner end of the connecting hole 42 is connected to the enlarged hole 43. The connector 47 has a movable cavity 46 in which a ball head 45 can be slidably connected. The movable cavity 46 is located in the enlarged hole 43 and gradually decreases in size. In use, the ball head 45 is pushed towards the smaller end of the movable cavity 46 by the push rod 44 fixed to the lower end of the ball head 45. This causes the end of the connector 47 located in the enlarged hole 43 to expand and lock, improving the firmness of the connection. When disassembly is required, the ball head 45 is pulled away from the enlarged hole 43 by the push rod 44, and the connector 47 returns to its original position, allowing for disassembly.
