Description

Technical Field

[0001] This invention relates to the field of bone injury fixation technology, specifically to an emergency shaping and fixation device for limb bone injuries. Background Technology

[0002] Bone injuries are usually caused by direct or indirect violence. Fractures caused by direct violence often occur at the site where the force is applied directly. For patients with limb bone injuries, it is crucial to quickly and effectively immobilize the injured limb. Proper immobilization can prevent displacement of the fracture ends, reduce further damage and pain, and also help stabilize the patient during transportation.

[0003] Currently, splints or clamps are generally used to clamp bone injuries. Splints require professional operation, are relatively cumbersome, and cannot be reshaped. Clamps are also specific to different patients, as the size of the limbs varies, making them less suitable for different injuries. Therefore, this application proposes an easy-to-carry, highly applicable, and reshaping emergency fixation device for limb bone injuries. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by proposing an emergency shaping and fixation device for limb bone injuries, aiming to solve the problems mentioned above.

[0005] This invention provides an emergency shaping and immobilization device for limb bone injuries, comprising: The shaped sheet can be rolled up and bent in multiple directions, and several through holes are provided on the shaped sheet; A flexible pad is wrapped around a molding plate and is rolled and bent in multiple directions along with the molding plate; limit holes are opened on the flexible pad corresponding to the through holes; The locking element is rotatably positioned within the through hole and the limiting hole; The tightening strap is attached to the clamp and rotates with the clamp to tighten the shaped molded plate onto the limb or to fix the splint used for shaping bone injuries. The protective sleeve is slidably mounted on the flexible pad, and has a folding part on it. The protective sleeve slides to the end of the plastic plate so that the folding part can seal the end of the plastic plate by folding.

[0006] Preferably, the shaping plate is an aluminum plate, and the flexible padding layer is a double-layer sponge, silicone, or foam cotton.

[0007] Preferably, the tightening band includes a bristle surface and a fiber surface. The bristle surface is connected to a clamp on one side of the shaping plate, and the fiber surface is connected to a clamp on the other side of the shaping plate. The bristle surface and the fiber surface are evenly distributed sequentially along the length of the shaping plate, so that two adjacent bristle surfaces and fiber surfaces located on one side of the shaping plate along its length can be combined by rotation to form a tightening band that is arranged along the length of the shaping plate.

[0008] Preferably, the tightening band is a bandage strip, with one end of the bandage strip fixed to the clip and the other end of the bandage strip being a free end.

[0009] Preferably, a number of patches are evenly distributed along the length of one side of the protective cover, and the patches are attached to the other side of the protective cover by folding the folding part.

[0010] Preferably, the vertical cross-section of the card is a T-shaped structure, so that the diameter of the limiting hole is larger than the diameter of the through hole, so that the card is limited within the limiting hole and the through hole.

[0011] Preferably, the shaping sheet is configured to be rolled up and bent along both the length and width directions.

[0012] Preferably, the shaping plate has a fixing hole in the middle, and the clamp plate has multiple connecting holes along the axial direction; it also includes a connector and a fixing member, the connector is located in the fixing hole, and the fixing member passes through the connecting hole and is rotatably inserted with the connector.

[0013] The connector has a protruding connecting part with an L-shaped hole on its tube wall and a square groove inside. The diagonal of the square groove and the line connecting the openings of the two L-shaped holes are on the same vertical plane. The inner wall of the end of the fastener has corresponding connecting protrusions on both sides. A square rod and a limiting rod are slidably installed inside the fastener. A spring is sleeved on the square rod. The directional rod is connected to the limiting rod. One end of the spring is connected to the end of the limiting rod. The other end of the square rod is connected to the limiting block inside the fastener. The fastener is inserted into the connector so that the connecting protrusion enters the L-shaped hole through the opening. The square rod elastically abuts against the square groove and is vertically offset. Rotating the fastener moves the connecting protrusion to its end in the lower end of the L-shaped hole, so that the square rod and the square groove are vertically aligned and inserted into the square groove.

[0014] Compared with existing technologies, it has the following technical advantages: By wrapping a double-layered flexible padding layer around a retractable and bendable shaping plate in multiple directions, the shaping plate can be molded to the shape of the limb with bone loss, thereby achieving shaping, positioning, and fixation of the limb with bone loss. The shaping plate and flexible padding layer are then secured to the limb by a multi-angle rotating tightening strap. It is portable and easy to operate in one piece, facilitating first aid for daily limb bone injuries and has strong applicability. At the same time, by sliding on the protective sleeve of the flexible padding layer, the flipping part can be flipped over to seal the cut shaping plate, preventing sharp parts of the shaping plate from scratching the limb during the cutting process.

Detailed Implementation

[0018] To better understand the structure, functional features, and advantages of the present invention, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings: Example 1: like Figures 1 to 6 As shown, the present invention provides an emergency shaping and fixation device for limb bone injuries, comprising: The shaping plate 1 can be rolled up and bent in multiple directions, and the shaping plate 1 has several through holes 11. The flexible pad 2 is wrapped around the shaping plate 1 and is rolled and bent in multiple directions along with the shaping plate 1; the flexible pad 2 has a limiting hole 21 corresponding to the through hole 11; The clip 3 is rotatably disposed within the through hole 11 and the limiting hole 21; The tightening strap 4 is connected to the clip 3 and rotates with the clip 3 to tighten the shaped shaping plate 1 onto the limb or to fix the splint 6 used for shaping bone injuries. The protective sleeve 5 is slidably disposed on the flexible pad 2, and a folding part 51 is provided thereon. The protective sleeve 5 slides to the end of the plastic plate 1 so that the folding part seals the end of the plastic plate 1 by folding.

[0019] The shaping board 1 is made of aluminum, which is easy to shape and has a certain degree of support strength. Combined with the flexible padding layer 2, it can be used as an emergency treatment option for limb bone injuries. The flexible padding layer 2 is made of double-layer sponge, silicone, or foam.

[0020] See Figure 2 A number of patches 52 are evenly distributed along the length of one side of the protective sleeve 5. The patches 52 are folded by the folding part 51 to fit with the other side of the protective sleeve 5, so that the flipping part can seal the end of the plastic plate 1 by folding, so as to prevent the sharp part generated during the cutting process of the plastic plate 1 from scratching the limbs, thereby avoiding secondary injury.

[0021] See Figure 1 The vertical cross-section of the clip 3 is a T-shaped structure, so that the diameter of the limiting hole 21 is larger than the diameter of the through hole 11, so that the clip 3 is confined within the limiting hole 21 and the through hole 11. The clip 3 is made of rubber or plastic material, and can also be made of aluminum.

[0022] See Figure 5 and Figure 6The shaping plate 1 is configured to be rolled up and bent along the length and width directions, so that the shaping plate 1 can be rolled up and bent along the length direction or along the width direction according to the size of the user's limb. When the limb is too large and the width of the shaping plate 1 cannot wrap the limb, the shaping plate 1 can be rolled up and bent along the length direction to wrap the limb. When the injured limb is long, the limb with bone injury can be clamped and fixed by splicing the shaping plate 1 with the splint 6.

[0023] Example 2: As another embodiment of the present invention, such as Figure 1 As shown, the tightening strap 4 includes a bristle surface 41 and a fiber surface 42. The bristle surface 41 is connected to a clip 3 on one side of the shaping plate 1, and the fiber surface 42 is connected to a clip 3 on the other side of the shaping plate 1. By setting the bristle surface 41 and the fiber surface 42, the bristle surface 41 and the fiber surface 42 can be connected to each other to fix the shaping plate 1 and the flexible pad 2 to the limb, and the splint 6 can also be fixed to the limb.

[0024] See Figure 1 The bristle surface 41 and the fiber surface 42 are evenly distributed along the length of the shaping plate 1, so that two adjacent bristle surfaces 41 and fiber surfaces 42 on one side of the length of the shaping plate 1 can be combined by rotation to form a tightening band 4 along the length of the shaping plate 1. This allows multiple bent and shaped shaping plates 1 to be spliced ​​together by fixing the clamping plate 6 with the tightening band 4, thereby enabling multiple shaping plates 1 to be wrapped around the limb after shaping, thus solving the problem that the width of the shaping plate 1 is insufficient to wrap the limb when the limb is large.

[0025] As an alternative, the tightening band 4 of the present invention can also be a bandage strip, with one end of the bandage strip fixed to the clip 3 and the other end of the bandage strip being a free end, so as to fix the shaping plate 1 and the flexible pad 2 to the limb by binding the free end.

[0026] Example 3: As another embodiment of the present invention, such as Figures 7 to 9 As shown, a fixing hole 12 is provided in the middle of the shaping plate 1, and multiple connecting holes 61 are provided along the axial direction on the clamping plate 6; it also includes a connector 7 and a fixing member 8. The connector 7 is disposed in the fixing hole 12, and the fixing member 8 passes through the connecting hole 61 and is rotatably inserted into the connector 7. In this embodiment, by providing fixing holes 12 and connecting holes 61 on the shaping plate 1 and the clamping plate 6, the fixing member 8 passing through the clamping plate 6 is inserted into the connector 7 on the shaping plate 1 to fix the clamping plate 6 to the shaping plate 1.

[0027] See Figures 9 to 11The connector 7 has a protruding connecting part 71, an L-shaped hole 72 on its tube wall, and a square groove 73 inside the connecting part 71. The inner wall of the end of the fixing member 8 has corresponding connecting protrusions 81 on both sides. A square rod 82 and a limiting rod 83 are slidably disposed inside the fixing member 8. A spring 84 is fitted onto the square rod 82. The directional rod is connected to the limiting rod 83. One end of the spring 84 is connected to the end of the limiting rod 83, and the other end of the square rod 82 is connected to a limiting block 85 inside the fixing member 8. A rotating piece is provided on the upper part of the limiting block 85; the fixing member 8 can be rotated by pinching the rotating piece with a finger.

[0028] In this embodiment, the diagonal of the square groove 73 and the line connecting the openings of the two L-shaped holes 72 are located on the same vertical plane. This allows the connecting protrusion 81 on the fixing member 8 to enter the L-shaped hole 72 through the opening on the connecting part 71 when the fixing member 8 is inserted into the connector 7. During this process, the square rod 82 elastically abuts against the square groove 73 and is vertically offset, pushing the square rod 82 to move upwards within the fixing member 8, where the tension spring 84 is stretched. Rotating the fixing member 8 causes the connecting protrusion... 81 moves to the end of the horizontal end of the L-shaped hole 72, causing the square rod 82 to rotate so that it is vertically aligned with the square groove 73. At this time, the square rod 82 is inserted into the square groove 73 under the action of the tension spring 84, so as to constrain the rotational freedom of the fixing member 8 and the connecting member 7. The axial movement of the fixing member 8 is further constrained by the connecting protrusion 81 located at the end of the L-shaped hole 72, so that the fixing member 8 can be rotatably inserted into the connecting member 7, so as to fix the clamping plate 6 to the plastic plate 1 and the flexible pad 2.

[0029] When it is necessary to remove the clamping plate 6 from the plastic plate 1 and the flexible pad 2, pull the rotating piece to drive the square rod 82 to stretch the spring 84 to retract and disengage from the square groove 73, thereby unlocking the rotational freedom of the fixing part 8. At this time, rotating the fixing part 8 will cause the connecting protrusion 81 to disengage from the L-shaped hole 72, thereby disengaging the fixing part 8 from the connecting part 7 and thus removing the clamping plate 6.

[0030] Furthermore, the shaping plate 1 and the flexible padding layer 2 are rolled onto a drum. One end of the drum is closed, and the other end is provided with an opening and closing cover. The drum is used to hold the connector 7 and the fixing member 8 for easy carrying. Furthermore, a partition is provided in the middle of the drum to divide the drum into two spaces for holding the connector 7 and the fixing member 8, and opening and closing covers are provided at both ends of the drum to open the spaces for the connector 7 and the fixing member 8 respectively.

[0031] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the present invention. Any person skilled in the art can make many possible variations and modifications to the technical solution of the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of the present invention without departing from the scope of the present invention are within the protection scope of the present invention.
