The outer ring of the connecting bearing is fixedly connected to the inner wall of the round hole formed on the surface of the support plate.

[0010] Preferably, the transmission gear rod is composed of a cross bar, a transmission bevel gear and a synchronous gear. The transmission bevel gear and the synchronous gear are respectively arranged at both ends of the cross bar. The surface of the transmission bevel gear meshes with the surface of the bevel gear tube. The surface of the synchronous gear meshes with the surface of the coating mechanism.

[0011] Preferably, the coating mechanism includes an end face gear. The end face gear is rotatably connected to the surface of the support plate. The surface of the end face gear meshes with one end of the transmission mechanism. An arc-shaped rack is fixedly connected to the outer ring of the end face gear;

[0012] A guide block is slidably connected inside the arc-shaped guide groove. On the surface of the support plate, an adjusting gear rod matching the arc-shaped rack is rotatably connected. A torsion spring is fixedly connected between the end of the adjusting gear rod and the inner wall of the support plate.

One end of the spring rod is fixedly connected with an arc-shaped medicine applying plate.

[0013] Preferably, the winding mechanism includes guide wheels. Four guide wheels are provided. The four guide wheels are rotatably connected to the surface of the support plate at equal intervals. A winding ring matching the transmission mechanism is movably connected between the four guide wheels. A tie wheel is rotatably connected to the surface of the winding ring;

[0014] The surface of the support plate is symmetrically provided with slot holes, and the surface of the clamping plate is symmetrically fixedly connected with arc-shaped blades. The two arc-shaped blades correspond to the two slot holes one by one. The surface of the clamping plate is symmetrically rotatably connected with wire pulling wheels, and a pulling rope is wound around the surface of the wire pulling wheels.

[0016] The directions of the two spring pressure rods are opposite.

[0017] A usage method of a field first aid device includes the following steps:

[0018] S1. When in use, adjust the open end of the winding ring to the groove end position of the support plate, and then the operator holds the support sleeve with one hand and clamps the arm through the clamping plate. Under the cooperation of the two spring pressure rods with opposite settings, the two arc-shaped clamping blocks on the clamping plate clamp the arm for support. Then, place the disinfected cotton on the surface of the arc-shaped medicine application plate so that the wound on the arm is in the direction position of the arc-shaped medicine application plate;

[0019] S2. Then, pull the support plate on the clamping plate to slide between the two sliding rods. The moving distance of the support plate is adjusted according to the length of the patient's wound. When the support plate is released, the compression spring presses against the support plate to move back to the clamping plate direction. At this time, the transmission gear rod is in meshing transmission with the top of the transmission rack through the circular gear, so that the two ends of the transmission gear rod are respectively in meshing transmission with the end face gear and the bevel gear tube. Then, the bevel gear tube drives the main synchronous wheel rod and the synchronous belt to operate through the one-way bearing. Under the cooperation of the slave synchronous wheel rod and the synchronous belt, the synchronous belt drives the winding ring to rotate on the side wall of the support plate. During the rotation of the winding ring and the movement of the support plate towards the clamping plate direction, the tie belt on the tie belt wheel automatically winds around the arm position;

[0020] S3. While the tie belt is winding, the rotating end face gear drives the arc-shaped rack to be meshed with the adjusting gear rod periodically, so that the adjusting gear rod drives the adjusting plate and the guide block to slide along the track of the arc-shaped guide groove. The connecting block on the guide block drives the arc-shaped medicine application plate to smear the wound position. When the arc-shaped rack is disengaged from the adjusting gear rod, the torsion spring drives the adjusting plate, the guide block and the arc-shaped medicine application plate to move back, so that the arc-shaped medicine application plate reciprocates along the track of the arc-shaped guide groove to smear the wound;

[0021] S4. Finally, when the circular gear is about to disengage from the transmission rack, the support plate gradually approaches the side wall position of the clamping plate. At this time, the winding ring gradually releases the rotating state, and the arc-shaped blade on the surface of the clamping plate inserts into the slot position. Due to the rotation of the cable tie wheel, the cable tie on the cable tie wheel contacts the arc-shaped blade and is automatically cut. Finally, the cable tie is adhered to the arm position with medical tape to complete the first aid bandaging.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] In the present invention, by the coordinated use of components such as the support plate, the transmission mechanism, and the winding mechanism, after the clamping plate and the support plate are clamped on the arm position, the support plate is pulled to move on the surface of the sliding rod. During the process of the support plate moving back towards the clamping plate, under the cooperation of the transmission mechanism and the winding mechanism, the cable tie on the cable tie wheel is automatically wound around the wound position of the arm, enabling single-handed operation and improving the convenience of use.

[0024] In the present invention, by the coordinated use of components such as the support plate, the transmission mechanism, and the coating mechanism, when the support plate moves back towards the clamping plate, under the cooperation of the transmission mechanism and the coating mechanism, the arc-shaped medicine application plate reciprocates along the trajectory of the arc-shaped guide groove to apply disinfectant to the wound position of the arm, avoiding the need for a separate disinfectant application operation and improving the first aid dressing efficiency.

[0025] In the present invention, by the coordinated use of components such as the support plate, the sliding rod, and the transmission mechanism, since the winding ring and the cable tie wheel perform the bandaging operation as the support plate moves, the patient can control the sliding distance of the support plate on the sliding rod according to the length of the wound and freely adjust the bandaging length.

A synchronous belt 707 is movably connected between the surface of the main synchronous wheel rod 706 and the two slave synchronous wheel rods 703. It should be noted that: through the setting of the one-way bearing 705, the bevel gear tube 704 can drive the main synchronous wheel rod 706 to rotate during the forward rotation process, and the main synchronous wheel rod 706 cannot be driven to rotate during the reverse rotation process of the bevel gear rod; during the rotation process of the main synchronous wheel rod 706, the transmission effect is achieved in cooperation with the synchronous belt 707 and the slave synchronous wheel rods 703.

[0042] The surface of the support plate 4 is fixedly connected with a protective cylinder 708 that cooperates with the bevel gear tube 704. The surface of the protective cylinder 708 is rotatably connected with a transmission gear rod 709 that cooperates with the bevel gear tube 704. One end of the transmission gear rod 709 away from the protective cylinder 708 is meshed with the surface of the coating mechanism 9. A circular gear 710 is fixedly sleeved in the middle of the transmission gear rod 709. The surface of the circular gear 710 is meshed with the surface of the transmission rack 702. It should be noted that: a support bearing is fixedly connected to the surface of the protective cylinder 708, and the transmission gear rod 709 is fixedly connected to the inner ring of the support bearing to ensure the rotational stability of the transmission gear rod 709.

[0043] In this embodiment, as Figures 1 to 10 shown, a circular hole is provided on the surface of the support plate 4. A connecting bearing is fixedly sleeved on the surface of the bevel gear tube 704, and the outer ring of the connecting bearing is fixedly connected to the inner wall of the circular hole provided on the surface of the support plate. It should be noted that: the setting of the connecting bearing ensures the stability of the bevel gear tube 704 during use.

[0044] In this embodiment, as Figures 1 to 10 shown, the transmission gear rod 709 is composed of a cross bar, a transmission bevel gear, and a synchronous gear. The transmission bevel gear and the synchronous gear are respectively arranged at both ends of the cross bar. The surface of the transmission bevel gear is meshed with the surface of the bevel gear tube 704, and the surface of the synchronous gear is meshed with the surface of the coating mechanism 9. It should be noted that: the surface of the synchronous gear is meshed and driven with the surface of the end face gear 901.

[0045] In this embodiment, as Figures 1 to 10 shown, the coating mechanism 9 includes an end face gear 901. The end face gear 901 is rotatably connected to the surface of the support plate 4. The surface of the end face gear 901 is meshed with one end of the transmission mechanism 7. An arc-shaped rack 902 is fixedly connected to the outer ring of the end face gear 901. It should be noted that: the surface of the end face gear 901 is meshed and driven with the end of the transmission gear rod 709.

[0046] A guide block 903 is slidably connected inside the arc-shaped guide groove 8. A regulating gear rod 904 that cooperates with the arc-shaped rack 902 is rotatably connected to the surface of the support plate 4. A torsion spring 905 is fixedly connected between the end of the regulating gear rod 904 and the inner wall of the support plate 4. A regulating plate 906 is fixedly connected to the surface of the regulating gear rod 904. A regulating groove 907 is formed in the surface of the regulating plate 906. The regulating plate 906 is slidably connected to the surface of the guide block 903 through the regulating groove 907. One end of the guide block 903 away from the arc-shaped guide groove 8 is fixedly connected with a connecting block 908. A spring rod 909 is fixedly connected to the surface of the connecting block 908. One end of the spring rod 909 is fixedly connected with an arc-shaped medicine application plate 910. It should be noted that: the cross-section of the arc-shaped guide groove 8 is set as a T shape. Positioning grooves are symmetrically formed in the inner wall of the arc-shaped guide groove 8. Positioning pins are symmetrically and fixedly connected to the surface of the guide block 903. The positioning pins are slidably connected inside the corresponding positioning grooves. Through the cooperation of the positioning grooves and the positioning pins, the guide block 903 can slide along the track of the arc-shaped guide groove 8, and the guide block 903 is prevented from rotating inside the arc-shaped guide groove 8; a magic tape is arranged on the surface of the arc-shaped medicine application plate 910, which is convenient for pasting disinfected cotton; when the arc-shaped rack 902 rotates along with the end face gear 901, the arc-shaped rack 902 and the regulating gear rod 904 are meshed and driven periodically, so that the regulating plate 906 drives the guide block 903 to slide along the track of the arc-shaped guide groove 8 through the regulating groove 907. At this time, the arc-shaped medicine application plate 910 smears the wound position.

[0047] In this embodiment, as Figures 1 to 10 shown, the winding mechanism 10 includes guide wheels 101. Four guide wheels 101 are rotatably connected to the surface of the support plate 4 at equal intervals. A winding ring 102 that cooperates with the transmission mechanism 7 is movably connected between the four guide wheels 101. A tie wheel 103 is rotatably connected to the surface of the winding ring 102. It should be noted that: an opening that cooperates with the groove 6 is formed in the surface of the winding ring 102. The outer surface of the winding ring 102 is attached to the surface of the synchronous belt 707. When the synchronous belt 707 runs, it will drive the winding ring 102 to rotate on the surface of the support plate 4; two guide wheels 101 are set as a group, and the two groups of guide wheels 101 are symmetrically arranged on both sides of the groove 6; when the two arc-shaped clamping blocks 14 on the clamping plate 1 clamp the arm position and complete the positioning and support of the arm, at this time, the operator pastes one end of the tie strap on the patient's arm position through a medical tape. Then, when the support plate 4 moves towards the clamping plate 1, the synchronous belt 707 on the transmission mechanism 7 will drive the winding ring 102 to rotate. The tie wheel 103 on the surface of the rotating winding ring 102 will wind and rotate along the patient's arm, so that the tie strap on the tie wheel 103 is tied to the patient's arm position. During this process, the tie wheel 103 slowly moves towards the clamping plate 1 along with the support plate 4, so that the tie strap can be evenly tied on the arm surface.

[0048] The surface of the support plate 4 is symmetrically provided with slot grooves 104. The surface of the clamping plate 1 is symmetrically fixedly connected with arc-shaped blades 105. The two arc-shaped blades 105 correspond to the two slot grooves 104 one by one. The surface of the clamping plate 1 is symmetrically rotatably connected with wire pulling wheels 106. A wire pulling rope 107 is wound around the surface of the wire pulling wheel 106. One end of the wire pulling rope 107 is fixedly connected with the surface of the support plate 4. It should be noted that: symmetrically arranged mounting grooves are provided on the surface of the clamping plate 1. The two wire pulling wheels 106 are respectively rotatably connected inside the two mounting grooves. A torsion spring is fixedly connected between the end of the wire pulling wheel 106 and the inner wall of the mounting groove. Through the cooperation of the torsion spring, the wire pulling wheel 106 and the wire pulling rope 107, it assists the support plate 4 to perform a reset movement in the direction of the clamping plate 1; when the support plate 4 moves in the direction of the clamping plate 1, when the arc-shaped blade 105 is inserted into the slot groove 104, the circular gear 710 gradually disengages from the driving rack 702. At this time, after the cable tie wound with the winding ring 102 stops rotating after being cut by the arc-shaped blade 105, and a damping bearing is provided between the cable tie wheel 103 and the winding ring 102 to ensure that the cable tie on the cable tie wheel 103 can be stably cut by the arc-shaped blade 105.

[0049] In this embodiment, as Figures 1 to 10 shown, the two arc-shaped clamping blocks 14 on the side wall of the clamping plate 1 are arranged symmetrically, and anti-slip teeth are provided on the surface of the arc-shaped clamping blocks 14.

[0050] The two spring pressure rods 12 are arranged in opposite directions. It should be noted that: since the adjacent two spring pressure rods 12 are arranged in opposite directions, when the two spring pressure rods 12 press against the arc-shaped clamping blocks 14, the arc-shaped clamping blocks 14 are in an inclined state. When the clamping plate 1 is clamped to the arm position, the two oppositely arranged arc-shaped clamping blocks 14 can clamp the arm, and the width of the arc-shaped clamping blocks 14 is set according to actual use to ensure the stability of clamping.

[0051] In this embodiment, as Figures 1 to 10 shown, a method for using a field first-aid device includes the following steps:

[0052] S1. When in use, adjust the open end of the winding ring 102 to the position of the groove 6 end of the support plate 4. Then, the operator holds the support sleeve 2 with one hand and clamps the arm through the clamping plate 1. With the cooperation of the two spring pressure rods 12 arranged in opposite directions, the two arc-shaped clamping blocks 14 on the clamping plate 1 clamp the arm for support. Then, place the sterilized cotton on the surface of the arc-shaped medicine application plate 910 so that the wound on the arm is in the direction of the arc-shaped medicine application plate 910;

[0053] S2. Then, pull the support plate 4 on the splint 1 to slide between the two slide bars 3. The moving distance of the support plate 4 is adjusted according to the length of the patient's wound. When the support plate 4 is released, the compression spring 5 presses against the support plate 4 to move it back in the direction of the splint 1. At this time, the transmission gear rod 709 is in meshing transmission with the top of the transmission rack 702 through the circular gear 710, so that the two ends of the transmission gear rod 709 are respectively in meshing transmission with the end face gear 901 and the bevel gear tube 704. Then, the bevel gear tube 704 drives the main synchronous wheel rod 706 and the synchronous belt 707 to operate through the one-way bearing 705. With the cooperation of the slave synchronous wheel rod 703 and the synchronous belt 707, the synchronous belt 707 drives the winding ring 102 to rotate on the side wall of the support plate 4. During the rotation of the winding ring 102 and its movement in the direction of the splint 1 along with the support plate 4, the tie on the tie wheel 103 automatically winds around the arm position;

[0054] S3. While the tie is being wound, when the support plate 4 moves in the direction of the splint 1, it will drive the arc-shaped medicine application plate 910 to translate synchronously. At the same time, the circular gear 710 meshes with the transmission rack 702 to drive the transmission gear rod 709 to rotate, so that the transmission gear rod 709 is in meshing transmission with the end face gear 901. The rotating end face gear 901 drives the arc-shaped rack 902 to be in meshing with the adjusting gear rod 904 periodically, so that the adjusting gear rod 904 drives the adjusting plate 906 and the guide block 903 to slide along the track of the arc-shaped guide groove 8. The connecting block 908 on the guide block 903 drives the arc-shaped medicine application plate 910 to apply medicine to the wound position. When the arc-shaped rack 902 is disengaged from the adjusting gear rod 904, the torsion spring 905 will drive the adjusting plate 906, the guide block 903 and the arc-shaped medicine application plate 910 to move back, so that the arc-shaped medicine application plate 910 reciprocates along the track of the arc-shaped guide groove 8 to apply medicine to the wound;

[0055] S4. Finally, when the circular gear 710 is about to be disengaged from the transmission rack 702, the support plate 4 also gradually approaches the side wall position of the splint 1. At this time, the winding ring 102 gradually stops rotating, and the arc-shaped blade 105 on the surface of the splint 1 is inserted into the slot 104. Due to the rotation of the tie wheel 103, the tie on the tie wheel 103 contacts the arc-shaped blade 105 and is automatically cut off. Finally, the tie is adhered to the arm position with medical tape to complete the first aid bundling.

[0056] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art of this industry should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention.
