Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a multifunctional limb trauma first aid fixation device for orthopedics. Background Art

[0002] Bone injury is a common injury. After a patient suffers a major trauma, emergency personnel usually fix the fracture site of the patient with a fixation plate and fix the fixation plate by wrapping multiple circles of bandages. After the treatment is completed, the patient is sent to the hospital. During the medical treatment, the damaged part of the limb is completely wrapped by multiple layers of bandages, which makes it difficult to detect bleeding in the limb in time. When medical staff observe bleeding through the bandage soaked with the patient's blood, the patient has lost a lot of blood, which is not conducive to the patient's subsequent treatment.

[0003] For example, a Chinese patent with publication number CN112972097B discloses a multifunctional orthopedic limb trauma first aid fixation device, which belongs to the technical field of first aid equipment. The first clamping plate and the second clamping plate of the fixation device are hinged on one side of the bottom, and the other side of the first clamping plate and the second clamping plate are connected by fasteners; the fastening plate is arranged on the side of the first clamping plate or the second clamping plate close to the limb, and a distance adjustment mechanism is provided between the fastening plate and the first clamping plate or the second clamping plate for adjusting the distance between the fastening plate and the first clamping plate or the second clamping plate; a thermochromic film is attached to the side of the fastening plate close to the limb trauma site, and the first clamping plate, the second clamping plate and the fastening plate are all made of transparent material for observing the color change of the color-changing film; a refrigeration device is arranged on the outside of the first clamping plate or the second clamping plate. The fixation device of the present invention can monitor the re-bleeding in a timely manner while fixing the injured limb.

[0004] Although the above-mentioned device can timely observe whether the patient's damaged part is bleeding through the changes produced when the thermochromic film comes into contact with blood, during actual use, the color-changing film in contact with the patient's limb is limited and blocked by the fastening plate, and the two fastening plates are limited and blocked by the first clamping plate and the second clamping plate, which is not conducive to medical staff to observe the status of the color-changing film in time, making it impossible for medical staff to deal with the patient's bleeding location in time, affecting the patient's treatment.

The knife seat 28 is fixedly connected to a pull rod 29 that passes through the knife seat 28, the first pressure plate 24 and extends to the outside of the first pressure plate 24. The two support rings 1 are fixedly connected to the same hanging rod 9. The first pressure plate 24 is fixedly connected to two hooks 32 that are compatible with the hanging rod 9. The limiting component 6 also includes a second adjusting bolt 17 that is threadedly connected to the support seat 5. The second adjusting bolt 17 is fixedly connected to a turning handle for facilitating the rotation of the second adjusting bolt 17. The second adjusting bolt 17 passes through the support seat 5 and conflicts with the second sliding rod 15.

[0042] By setting the first splint 4, the limiting component 6, the second splint 7, and the bandage splint 8, before use, the bandage is passed through the first through slot 22, and is clamped and limited by the first pressing plate 24 and the second pressing plate 25, and the first pressing plate 24 and the second pressing plate 25 with the bandage are limited by the clamping of the buckle 26 and the first pressing plate 24, and the first pressing plate 24 with the bandage is hung on the hanging rod 9 through the hook 32, and the bandage is pressed down until it touches the two first splints 4, and the patient's damaged limb is passed through the bandage so that it is pressed down by gravity and supported by the two first splints 4, and the second adjusting bolt 17 is adjusted to release the limitation of the second slide bar 15, and the second splint 7 is pressed down until it contacts the upper surface of the affected limb and then passed through the second adjusting bolt. The bolt 17 squeezes and limits the second slide bar 15. During this process, the first pressure plate 24 can be placed on the bottom plate 20, so that the second slide bar 15 is inserted into the adapter groove 31 during the downward pressing process, and the top of the first pressure plate 24 is resisted and limited by the limiting plate 16, so that when the top of the affected limb is limited by the second adjusting bolt 17, the first pressure plate 24 and the second pressure plate 25 are limited synchronously, and the single-layer strap tied to the affected limb is limited by the second splint 7, the bandage splint 8, and the two first splints 4, while reducing the obstruction of the strap, improving the fixation efficiency of the affected limb, and allowing medical staff to observe in time when the patient's limb bleeds, and deal with the bleeding position of the patient, thereby ensuring the efficiency of the patient's treatment.

[0043] By setting the cutting component 33, after the fixation of the affected limb is completed, the pull rod 29 is pulled, and the pull rod 29 drives the knife seat 28 to cut the bandage near the first through groove 22. After cutting, the two ends of the bandage are fixed under the clamping limit of the first pressure plate 24, the second pressure plate 25 and the clamping limit of the first pressure plate 24 and the bottom plate 20. The structure is simple and easy to use.

[0044] By setting the limiting component 6, when bleeding is observed in the patient's affected limb, the second adjusting bolt 17 can be contacted to limit the second slide bar 15, and the bottom plate 20 and the first pressure plate 24 can be lifted. The second slide bar 15 and the adapter groove 31 can be released, and the buckle 26 can be engaged with the first pressure plate 24 to contact the limit of the affected limb and the bandage, which is convenient for medical staff to treat the affected limb and the operation is simple.

[0045] As another implementation of this embodiment, the support ring 1 can be disconnected on the side where the support seat 5 and the hanging rod 9 are close to each other, and connected by a snap-fit structure. The two support rings 1 are rotated and connected by a fixed axis at a symmetrical position of the disconnection position on the support ring 1. The advantage of this arrangement is that when the patient's limb needs to be fixed, the two support rings 1 can be opened, and the affected limb can be directly placed on the bandage that passes through the base plate 20 and is limited by the first pressure plate 24 and the second pressure plate 25. At the same time, the first pressure plate 24 is hung on the hanging rod 9 by a hook 32. At this time, under the action of the gravity of the affected limb, the bandage is pressed down until it conflicts with the two first splints 4. At this time, the open ends of the two support rings 1 are closed by the snap-fit structure, and the affected limb can be fixed by adjusting the second splint 7, thereby improving the fixation speed of the affected limb and ensuring the efficiency of patient first aid.

[0046] like Figure 4 and Figure 5 As shown, in this embodiment, the end of the tool holder 28 away from the pull rod 29 is in conflict with the second through groove 27, and the end of the pull rod 29 away from the tool holder 28 is provided with a bent portion, and a limit block 30 for limiting the bent portion is fixedly connected to the first pressure plate 24. By providing the bent portion and the limit block 30, under normal circumstances, the tool holder 28 and the pull rod 29 can be limited by the conflict between the bent portion and the limit block 30. When the pull rod 29 needs to be operated, the pull rod 29 can be deformed by applying force to the pull rod 29 and disengaged from the limit block 30, and then the pull rod 29 can be pulled. The structure is simple and the operation is convenient.

[0047] like Figure 1 and Figure 3 As shown, in this embodiment, a limiting strip 21 is fixedly connected to the second clamping plate 7, and the limiting strip 21 conflicts with the top of the first pressing plate 24. By setting the limiting strip 21, the assembly efficiency of the first pressing plate 24 and the bottom plate 20 is improved, the structure is simple, and it is easy to use.

[0048] like Figure 3As shown, in this embodiment, a knife groove 23 adapted to the knife seat 28 is provided on the second clamping plate 7. By providing the knife groove 23, interference between the blade of the knife seat 28 and the bottom plate 20 is avoided when the first pressure plate 24 and the bottom plate 20 are assembled, thereby ensuring the normal use of the device.

[0049] like Figure 4 As shown, in this embodiment, a plurality of matching anti-slip grooves are provided on the side where the first pressure plate 24 and the second pressure plate 25 are close to each other. The matching anti-slip grooves engage with each other to increase the friction on the bandage, thereby preventing the bandage from shifting during use and ensuring the binding effect of the bandage on the affected limb.

[0050] like Figure 2 As shown, in this embodiment, the supporting component 3 includes an outer sleeve 10 fixedly connected to the connecting plate 2, and a first slide rod 11 rotatably connected to the first splint 4 is slidably sleeved on the outer sleeve 10, and a first adjusting bolt 13 that passes through the outer sleeve 10 is threadedly connected to the outer sleeve 10, and a turning handle is fixedly connected to the first adjusting bolt 13 to facilitate operation of the first adjusting bolt 13, and the first adjusting bolt 13 is in conflict with the first slide rod 11, and a spring 12 is fixedly connected to the connecting plate 2, and the spring 12 is in conflict with the first slide rod 11. By setting the spring 12, it is convenient to elastically support the first slide rod 11 and the first splint 4 through the spring 12 during the process of the affected limb squeezing the first splint 4, thereby improving the fit between the first splint 4 and the affected limb and ensuring the fixation effect of the affected limb.

[0051] By setting up the support component 3, after the affected limb is clamped, limited and supported by the first splint 4, the first adjusting bolt 13 can be rotated to make the first adjusting bolt 13 come into conflict with the first slide bar 11, and then the first splint 4 can be limited by the first slide bar 11, thereby avoiding the first splint 4 from being offset during the process of clamping and limiting the affected limb by the support seat 5 and the two first splints 4, thereby affecting the fixation stability of the affected limb. At the same time, the rotational connection between the first splint 4 and the first slide bar 11 facilitates adaptation to the large and small ends of the limb, increases the scope of application of the device, and further improves the fixation effect of the affected limb.

[0052] like Figure 1 As shown, in this embodiment, the cross section of the second sliding rod 15 is rectangular, so that the top plate 18 will not deflect during the movement, thereby ensuring the clamping effect of the bottom plate 20 on the affected limb.

[0053] The technical solution provided by the present invention is to provide a first splint, a limiting component, a second splint, and a bandage splint. Before use, the bandage is passed through the first through slot and clamped and limited by the first pressure plate and the second pressure plate. The first pressure plate and the second pressure plate with the bandage are limited by the clamping connection with the first pressure plate. The first pressure plate with the bandage is hung on the hanging rod through a hook, and the bandage is pressed down until it touches the two first splints. The patient's damaged limb is passed through the bandage so that the bandage is pressed down under the action of gravity and supported by the two first splints. The second adjusting bolt is adjusted to release the limit on the second sliding rod. The second splint is pressed down until it contacts the upper surface of the affected limb and then passed through the second adjusting bolt. The second adjusting bolt squeezes and limits the second sliding rod. During this process, the first pressure plate can be placed on the bottom plate, so that the second sliding rod is inserted into the adapter groove during the downward pressing process, and the top of the first pressure plate is resisted and limited by the limiting plate, so that when the top of the affected limb is limited by the second adjusting bolt, the first pressure plate and the second pressure plate are limited synchronously, and the single-layer strap tied to the affected limb is limited by the second splint, the bandage splint, and the two first splints, while reducing the obstruction of the strap, improving the fixation efficiency of the affected limb, and allowing medical staff to observe in time when the patient's limb bleeds, and deal with the bleeding position of the patient, thereby ensuring the efficiency of the patient's treatment.

[0054] By setting up a cutting component, after the affected limb is fixed, the pull rod is pulled, and the pull rod drives the knife holder to cut the bandage near the first through groove position. After cutting, the two ends of the bandage are fixed under the clamping limit of the first pressure plate, the second pressure plate and the clamping limit of the first pressure plate and the bottom plate. The structure is simple and easy to use.

[0055] By setting a limiting component, when bleeding is observed in the patient's affected limb, the second adjusting bolt can be contacted to limit the second slide bar, the bottom plate and the first pressure plate can be lifted, and the second slide bar and the adapter slot can be released. The buckle is engaged with the first pressure plate, and the limit of the affected limb and the bandage can be contacted, which is convenient for medical staff to treat the affected limb and the operation is simple.

[0056] By setting the bending part and the limit block, under normal circumstances, the tool holder and the pull rod can be limited by the interference between the bending part and the limit block. When the pull rod needs to be operated, force can be applied to the pull rod to deform it and disengage it from the limit block before pulling it. The structure is simple and the operation is convenient.

[0057] The assembly efficiency of the first pressing plate and the bottom plate is improved by setting the limit bar, the structure is simple and easy to use, and the knife groove is provided to avoid the interference between the blade of the knife seat and the bottom plate when the first pressing plate and the bottom plate are assembled.

[0058] To ensure the normal use of the device, the friction on the bandage is increased by the mutual engagement of the matching anti-slip grooves, 5 which prevents the bandage from shifting during use and ensures the binding effect of the bandage on the affected limb.

[0059] By setting the supporting component, after the first splint is used to clamp and support the affected limb, the first adjusting bolt can be rotated to make the first adjusting bolt contact with the first sliding rod, and then the first splint can be limited by the first sliding rod, avoiding the process of clamping and limiting the affected limb by the support seat and the two first splints.

[0060] The first splint is offset, affecting the fixation stability of the affected limb. At the same time, the 0-rotation connection between the first splint and the first slide bar facilitates adaptation to the large and small ends of the limb, increases the scope of application of the device, and further improves the fixation effect of the affected limb.

[0061] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, the following preferred embodiments of the present invention are described in detail.
