Description

Technical Field

[0001] This application relates to the technical field of medical devices, and particularly to a medical polymer splint. Background Art

[0002] In the medical field, fractures and soft tissue injuries are common clinical problems. For these injuries, external fixation technology has become an important treatment method. Traditional external fixation methods, such as using plaster bandages, although they can play a certain role in fixation, have problems such as heavy weight, unreliable fixation, and poor air permeability, which affect the rehabilitation effect and quality of life of patients.

[0003] In this context, medical polymer splints have emerged. Such splints use polymer materials as the main body, combining the latest achievements of modern materials science, providing a new solution for the external fixation of fractures and soft tissue injuries. Polymer materials have excellent mechanical properties and biocompatibility, can provide good support and stability, and at the same time reduce the irritation and adverse reactions to human tissues.

[0004] The installation process of medical polymer splints usually involves accurately evaluating the injured area, customizing a splint of appropriate size, and tightly fitting it to the affected area through specific fixing devices such as screws or bandages. However, although the hardness, toughness, and conformability of the splint provide stability for fixation, when using bandages or screws for fixation, the cumbersome installation process is likely to cause additional pain to the patient during fixation, affecting the installation efficiency of medical polymer splints. Summary of the Utility Model

[0005] The purpose of this application is to: solve the problem that the cumbersome installation process is likely to cause additional pain to the patient during fixation when using bandages or screws for fixation, affecting the installation efficiency of medical polymer splints. This application provides a medical polymer splint.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0007] A medical polymer splint, comprising fixing bands symmetrically arranged, an elastic band fixedly connected between the two fixing bands, a connecting band I fixedly connected to one end of one of the fixing bands, a connecting band II fixedly connected to one end of the other fixing band, a pair of traction buckles fixedly connected to one end of the connecting band II, an L-shaped mounting bracket fixedly connected to one end of the connecting band I, a cross-shaped locking disc movably connected inside the L-shaped mounting bracket, an elastic locking tooth ring fixedly connected to the inner side of the L-shaped mounting bracket, a plurality of locking blocks adapted to the elastic locking tooth ring fixedly connected evenly around the periphery of the cross-shaped locking disc, a winding wheel rotatably connected inside the L-shaped mounting bracket, a traction band fixedly connected to one end of the connecting band I, one end of the traction band bypassing the two traction buckles and fixedly connected to the winding wheel, a plurality of polymer plates installed inside the fixing band, a synchronization component installed at one end of the cross-shaped locking disc for driving the winding wheel to rotate synchronously, and a connecting component installed inside the fixing band for fixing the polymer plates.

[0008] By adopting the above technical solution, through the combined use of the connecting component and the synchronization component, after attaching a plurality of polymer plates to the patient's injured area by pulling the fixing band in cooperation with the connecting component, pull one end of the traction band around the two traction buckles, and drive the winding wheel to complete the winding of one end of the traction band by tightening the cross-shaped locking disc. At the same time, cooperate with the elastic locking tooth ring and the locking block to fix the cross-shaped locking disc, so that the traction band pulls the connecting band I and the connecting band II to drive the two fixing bands to be tightened and fixed, thereby facilitating the quick fixing and fitting of a plurality of polymer plates to the patient's injured area, improving the installation efficiency of the polymer plates, and reducing the pain of the patient.

[0009] Further, the synchronization component includes a storage groove opened at one end of the winding wheel, synchronization sliding grooves symmetrically opened inside the storage groove, synchronization sliding blocks symmetrically fixedly connected to one end of the cross-shaped locking disc, and the synchronization sliding blocks are slidably connected inside the synchronization sliding grooves.

[0010] By adopting the above technical solution, through the combined use of the synchronization sliding grooves and the synchronization sliding blocks, when rotating the cross-shaped locking disc, it is convenient for the cross-shaped locking disc to drive the synchronization sliding blocks to contact the inner wall of the synchronization sliding grooves, and drive the winding wheel and the cross-shaped locking disc to rotate synchronously, so as to drive the winding wheel and the cross-shaped locking disc to rotate synchronously, improving the practicability of the device.

[0011] Further, a locking spring is fixedly connected to one end of the cross-shaped locking disc, and the locking spring is installed inside the storage groove.

[0012] By adopting the above technical solution, through the combined use of the storage groove and the locking spring, it is convenient to use the resilience of the locking spring to eject the cross locking disc, so that the cross locking disc drives the locking block to embed into the elastic locking tooth ring, thereby facilitating the promotion of the cross locking disc to drive the locking block to insert into the elastic locking tooth ring, improving the practicability of the device.

[0013] Further, one end of the cross locking disc passes through the L-shaped mounting bracket and is fixedly connected with a locking knob.

[0014] By adopting the above technical solution, through the combined use of the locking knob and the cross locking disc, the friction force on the surface of the cross locking disc is effectively increased, and the efficiency of rotating the cross locking disc is improved.

[0015] Further, the connecting component includes an elastic ring belt fixedly connected to the inner side of the fixing belt. One end of the elastic ring belt is symmetrically provided with clamping grooves, and one end of the polymer plate is inserted into the clamping grooves.

[0016] By adopting the above technical solution, through the combined use of the clamping groove and the elastic ring belt, it is convenient to utilize the elastic property of the elastic ring belt. When pulling the polymer plate to insert into the clamping groove, the inner wall of the clamping groove shrinks to lock the polymer plate, thereby realizing the rapid connection of the polymer plate and the fixing belt, improving the practicability of the device.

[0017] Further, a plurality of ventilation holes are uniformly arranged at one end of the fixing belt.

[0018] By adopting the above technical solution, the air permeability of the surface of the fixing belt is effectively improved by arranging the ventilation holes, and the comfort of the device is improved.

[0019] Further, an elastic airbag is fixedly connected to the inner side of the elastic band. One end of the elastic airbag is fixedly connected with an electromagnetic valve. A pressure sensor is arranged inside the elastic airbag, and the electromagnetic valve is electrically connected with the pressure sensor.

[0020] By adopting the above technical solution, through the combined use of the electromagnetic valve and the pressure sensor, when the pressure at the patient's injury site increases, the electromagnetic valve is controlled by the pressure sensor to open and release the air inside the elastic airbag, so that the elastic airbag generates a contraction deformation, thereby reducing the pressure at the patient's injury site and improving the safety of the device.

[0021] Further, two traction buckles are symmetrically and fixedly connected to one side of the connecting belt two, and the L-shaped mounting bracket is installed between the two traction buckles.

[0022] By adopting the above technical solution, by symmetrically installing two traction buckles on both sides of the L-shaped mounting bracket, when the traction belt bypasses the two traction buckles, a triangular traction structure is formed between the L-shaped mounting bracket and the two traction buckles, improving the connection stability between the first connecting belt and the second connecting belt.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. By setting the cooperation of the connection component and the synchronization component, after attaching multiple polymer sheet pieces to the patient's injury site through the traction fixing belt in cooperation with the connection component, the end of the traction belt bypassing the two traction buckles is pulled, and the winding wheel is driven to complete the winding of one end of the traction belt by tightening the cross-lock disc. At the same time, the cross-lock disc is fixed by cooperating with the elastic locking tooth ring and the locking block, so that the traction belt pulls the first connecting belt and the second connecting belt to drive the two fixing belts to be tightened and fixed, thereby facilitating the quick fixing and fitting of multiple polymer sheet pieces on the patient's injury site, improving the installation efficiency of the polymer sheet pieces, and reducing the pain of the patient.

[0025] 2. By setting the cooperation of the solenoid valve and the pressure sensor, when the pressure at the patient's injury site increases, the solenoid valve is controlled by the pressure sensor to open and release the air inside the elastic airbag, causing the elastic airbag to contract and deform, thereby reducing the pressure at the patient's injury site and improving the safety of the device.

[0031] The following is a further detailed description of the present application in conjunction with the attached Figures 1 - 3 drawings.

[0032] An embodiment of the present application discloses a medical polymer splint.

[0033] Referring to Figures 1 - 3 , a medical polymer splint includes fixing straps 1 symmetrically arranged. An elastic band 2 is fixedly connected between the two fixing straps 1. One end of a fixing strap 1 is fixedly connected to a connecting strap 3, and one end of the other fixing strap 1 is fixedly connected to a connecting strap 4. One end of the connecting strap 4 is fixedly connected to a pair of traction buckles 5. One end of the connecting strap 3 is fixedly connected to an L-shaped mounting bracket 6. A cross-shaped locking disc 7 is movably connected inside the L-shaped mounting bracket 6. An elastic locking tooth ring 8 is fixedly connected to the inner side of the L-shaped mounting bracket 6. A plurality of locking blocks 9 adapted to the elastic locking tooth ring 8 are evenly and fixedly connected to the periphery of the cross-shaped locking disc 7. A winding wheel 10 is rotatably connected inside the L-shaped mounting bracket 6. One end of the connecting strap 3 is fixedly connected to a traction belt 11. One end of the traction belt 11 bypasses the two traction buckles 5 and is fixedly connected to the winding wheel 10. A plurality of polymer plates 12 are installed on the inner side of the fixing strap 1. A synchronous component for driving the winding wheel 10 to rotate synchronously is installed at one end of the cross-shaped locking disc 7. A connecting component for fixing the polymer plates 12 is installed on the inner side of the fixing strap 1;

[0034] Among them, the synchronous component includes a receiving groove 13 opened at one end of the winding wheel 10. Synchronous sliding grooves 14 are symmetrically opened inside the receiving groove 13. Synchronous sliding blocks 15 are symmetrically and fixedly connected to one end of the cross-shaped locking disc 7. The synchronous sliding blocks 15 are slidably connected inside the synchronous sliding grooves 14;

[0035] Moreover, a locking spring 16 is fixedly connected to one end of the cross-shaped locking disc 7. The locking spring 16 is installed inside the receiving groove 13;

[0036] Moreover, one end of the cross-shaped locking disc 7 passes through the L-shaped mounting bracket 6 and is fixedly connected to a locking knob 17;

[0037] Moreover, the two traction buckles 5 are symmetrically and fixedly connected to one side of the connecting strap 4. The L-shaped mounting bracket 6 is installed between the two traction buckles 5.

[0038] During use, first, a plurality of polymer sheets 12 are fixed inside the fixing belt 1 by using a connecting component. Then, the fixing belt 1 is pulled to drive the polymer sheets 12 to adhere to the patient's injury site. The traction belt 11 is manually pulled around one end of the traction buckle 5. Then, by rotating the locking knob 17, the cross-shaped locking disc 7 is driven to drive the locking block 9 to squeeze the elastic locking tooth ring 8 to deform, and the winding wheel 10 is driven to rotate. As a result, the winding wheel 10 drives one end of the traction belt 11 to wind up. At the same time, the traction belt 11 is pulled around one end of the two traction buckles 5, and the connecting belt 1 and the connecting belt 2 are pulled together, so that the connecting belt 1 and the connecting belt 2 drive the two fixing belts 1 to tighten and fix. At the same time, the elastic locking tooth ring 8 rebounds and forms a fixation on the locking block 9;

[0039] Next, when it is necessary to release the tightening and fixation of the two fixing belts 1, by squeezing the locking knob 17, the cross-shaped locking disc 7 is pushed into the interior of the receiving groove 13, and the cross-shaped locking disc 7 drives the synchronous slider 15 to squeeze the locking spring 16 along the length direction of the synchronous sliding groove 14 to generate a contraction deformation. At the same time, the locking knob 17 pushes the cross-shaped locking disc 7 to drive the locking block 9 to disengage from the interior of the elastic locking tooth ring 8, thereby releasing the meshing fixation between the cross-shaped locking disc 7 and the elastic locking tooth ring 8. Then, by loosening the locking knob 17, the cross-shaped locking disc 7 is driven to drive the winding wheel 10 to rotate, and the tightening of the traction belt 11 is released, so as to release the tightening and fixation of the two fixing belts 1;

[0040] Finally, by withdrawing the extrusion force on the cross-shaped locking disc 7, the locking spring 16 rebounds to push the cross-shaped locking disc 7 to move along the length direction of the synchronous sliding groove 14 into the interior of the elastic locking tooth ring 8, and the cross-shaped locking disc 7 drives the locking block 9 to be inserted into one end of the elastic locking tooth ring 8, so as to drive the cross-shaped locking disc 7 to drive the locking block 9 to be received into the interior of the elastic locking tooth ring 8. This facilitates quickly fixing and attaching a plurality of polymer sheets 12 to the patient's injury site, improves the installation efficiency of the polymer sheets 12, and reduces the pain of the patient.

[0041] Referring to Figure 1 and Figure 3 As shown, the connecting component includes an elastic ring belt 18 fixedly connected to the inner side of the fixing belt 1. One end of the elastic ring belt 18 is symmetrically provided with a card slot 19, and one end of the polymer sheet 12 is inserted into the interior of the card slot 19;

[0042] Among them, a plurality of ventilation holes 20 are uniformly opened at one end of the fixing belt 1.

[0043] During use, first manually expand the inner wall of the card slot 19. Utilize the elastic property of the elastic ring belt 18 to expand the inner wall of the card slot 19, and insert the traction polymer sheet 12 into the interior of the card slot 19 through traction. Then, utilize the rebound property of the elastic ring belt 18 to contract the inner wall of the card slot 19 to lock and secure the polymer sheet 12, thereby achieving the rapid connection of the polymer sheet 12 and the fixing belt 1, improving the practicality of the device. At the same time, by providing ventilation holes 20, the air permeability of the surface of the fixing belt 1 is improved, thereby enhancing the comfort of the device.

[0044] Refer to Figure 1 and Figure 3 On the inner side of the elastic band 2, an elastic airbag 21 is fixedly connected. One end of the elastic airbag 21 is fixedly connected to a solenoid valve 22. A pressure sensor is arranged inside the elastic airbag 21, and the solenoid valve 22 is electrically connected to the pressure sensor.

[0045] During use, first inflate the interior of the elastic airbag 21 through the solenoid valve 22 externally connected to an air pump box, so that the elastic airbag 21 fits against the injured part of the patient, and the elastic airbag 21 drives the pressure sensor to fit against the injured part of the patient. When the pressure at the injured part of the patient increases, use the pressure sensor to send a control signal to the solenoid valve 22, causing the solenoid valve 22 to open and release the air inside the elastic airbag 21 outward, causing the elastic airbag 21 to undergo a contraction deformation, thereby reducing the pressure on the injured part of the patient and improving the safety of the device.

[0046] The implementation principle of a medical polymer splint in this embodiment is as follows: First, manually expand the inner wall of the card slot 19. Utilize the elastic property of the elastic ring belt 18 to expand the inner wall of the card slot 19, and insert the traction polymer sheet 12 into the interior of the card slot 19 through traction. Then, utilize the rebound property of the elastic ring belt 18 to contract the inner wall of the card slot 19 to lock and secure the polymer sheet 12. Then, pull the fixing belt 1 to drive the polymer sheet 12 to adhere to the injured part of the patient, and manually pull the traction belt 11 around one end of the traction buckle 5;

[0047] Then, rotate the locking knob 17 to drive the cross locking disc 7 to drive the locking block 9 to squeeze the elastic locking tooth ring 8 to deform, and drive the winding wheel 10 to rotate. As a result, the winding wheel 10 drives one end of the traction belt 11 to wind, and at the same time, pulls the traction belt 11 around one end of the two traction buckles 5, and pulls together the connecting belt one 3 and the connecting belt two 4, thereby causing the connecting belt one 3 and the connecting belt two 4 to drive the two fixing belts 1 to tighten and fix, and at the same time enabling the elastic locking tooth ring 8 to have a rebound property and form a fixation for the locking block 9;

[0048] At the same time, inflate the interior of the elastic airbag 21 through the solenoid valve 22 externally connected to an air pump box, so that the elastic airbag 21 fits against the injured part of the patient, and the elastic airbag 21 drives the pressure sensor to fit against the injured part of the patient.

[0049] Then, when it is necessary to release the tightening and fixing of the two fixing straps 1, by squeezing the locking knob 17, the cross locking disc 7 is pushed to move inside the storage groove 13, and the cross locking disc 7 drives the synchronous slider 15 to squeeze the locking spring 16 along the length direction of the synchronous sliding groove 14 to generate a contraction deformation. At the same time, the locking knob 17 pushes the cross locking disc 7 to drive the locking block 9 to disengage from the inside of the elastic locking tooth ring 8, so as to release the meshing and fixing between the cross locking disc 7 and the elastic locking tooth ring 8. Then, by loosening the locking knob 17, the cross locking disc 7 is driven to rotate the winding wheel 10, and the tightening of the traction belt 11 is released, so as to facilitate the release of the tightening and fixing of the two fixing straps 1.
