Description

Technical Field

[0001] The invention relates to the technical field of pediatric orthopedic treatment, in particular to a traction device for preventing skin damage in pediatric orthopedics. Background Art

[0002] There are many differences between children's bones and adult bones. Children's bones are highly plastic and have high regenerative capacity. There are so-called growth plates at both ends of children's bones. The outer periphery of the bones is covered with a layer of strong and thick periosteum. The growth plate is the cartilage tissue responsible for bone growth, and the periosteum is rich in blood circulation. All these make children's bones grow rapidly with age. For children's bone deformation and bone bending that may occur during growth, they are generally corrected by traction devices. Traction is a commonly used treatment method in orthopedics. This product assists the implementation of traction and improves the traction effect. The foot fixing piece is an indispensable part of the traction device.

[0003] When using the existing traction device, it is first necessary to use a foot fixing piece to fix the child's feet or legs, and then continue to pull the traction training. However, due to the cold winter, fixing the traction device on the child's feet or legs for a long time is prone to frostbite, especially in some home treatment environments without heating conditions, which is not conducive to the blood circulation of the child's feet or legs, and is not conducive to the child's recovery.

[0004] Therefore, we designed a traction device for pediatric orthopedics to prevent skin damage and to solve the above problems. Summary of the invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0025] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] See also Figure 1-6 The present invention provides a technical solution: a traction device for preventing skin damage in pediatric orthopedics, comprising a fixing belt 1 that can be bent into a "circular shape", and also comprising: The fixing member 2 is adapted to the diameter of the inner ring of the fixing belt 1 and is fixedly installed on the inner ring of the fixing belt 1; The connecting member 3 is arranged on one side of the fixing member 2, and a connecting column 4 is fixedly mounted on one end thereof; The fixing strip 5 has a width corresponding to the fixing belt 1 and is fixedly connected to an end of the connecting column 4 away from the connecting member 3; The connecting rod 6 is arranged in the horizontal direction and is arranged on one side of the fixing strip 5. A thermal pad 7 is fixedly installed on the other end of the connecting rod 6, and the thermal pad 7 abuts against the fixing strip 1. The heating block 8 with an electric heating wire embedded therein is installed on one side of the thermal pad 7 and is used to generate heat and transfer its heat energy to the fixing belt 1 and the fixing member 2 .

[0027] During specific implementation, after fixing the feet and legs, turn on the heating block 8, so that the electric heating wire in the heating block 8 heats up and transfers the heat to the fixing belt 1, the fixing part 2 and the child's fracture, so that the heat can promote blood circulation at the fracture site, accelerate metabolism, and thus help the child's bone recovery.

[0028] It should be noted here that in order to prevent the heating block 8 from scalding other people, we can set a heat insulation cover on the outside of the heating block 8 to cover the heating block 8, thereby preventing people from contacting the heating block 8 and getting scalded, thereby improving safety.

[0029] A plurality of fixing stickers 22 are arranged on the top of one end of the fixing belt 1 . The fixing belt 1 is made of polyester fiber, and the fixing stickers 22 are bonded to the top of the other end of the fixing belt 1 .

[0030] In the specific implementation, based on the above implementation, first place the fractured foot or leg of the child on the inner circle of the fixing piece 2, then bend the fixing belt 1 and the fixing piece 2 so that the two ends are against each other, and then adhere the fixing patch 22 to the top of the end of the fixing belt 1 away from the fixing patch 22, so that the child's foot or leg can be fixed and can be conveniently pulled.

[0031] See also Figure 1-6 A slide rail 9 is provided at one end of the fixing member 2, and the connecting member 3 is slidably inserted in the slide rail 9. By pulling the connecting member 3, the fixing bar 5 and the heating block 8 can be driven by the connecting member 3 to slide along the direction in which the slide rail 9 is set, and the position of the heating block 8 on the fixing belt 1 can be adjusted, so as to actively find the position of the child's bone injury, thereby further improving the heating effect of the traction device.

[0032] It should be noted here that, for the slide rail 9, in order to avoid the problem of the connecting member 3 slipping out of the slide rail 9, we can open slideways at the top and bottom of the slide rail 9, and install sliding members at the top and bottom of the connecting member 3. The sliding members are slidably inserted in the slideways, and the connecting member 3 can be limited in the direction of the outside of the slide rail 9 to avoid the problem of the connecting member 3 slipping out of the slide rail 9.

[0033] See also Figure 1-6 A slide rod 10 is slidably inserted on one side of the fixed strip 5, a positioning plate 11 is provided at one end of the slide rod 10, the positioning plate 11 is against the fixed belt 1, a pull block 12 is provided at the other end of the slide rod 10, and a support spring 13 is provided on the movable sleeve of the slide rod 10, and the two ends of the support spring 13 are respectively fixedly connected to the opposite side of the fixed strip 5 and the pull block 12.

[0034] In specific implementation, based on the above implementation, after the connector 3 has adjusted its position, the elastic force of the support spring 13 can pull the pull block 12 to move, so that the positioning plate 11 is against the fixing belt 1, and the connector 3 can be positioned to avoid shaking and deviation of the connector 3 during use, thereby improving stability during use.

[0035] The outer surface of the pull block 12 is provided with anti-skid patterns, which can increase the friction between the hand of the person and the pull block 12, thereby helping to solve the problem of slipping when the pull block 12 is pulled.

[0036] See also Figure 1-6 An iron bar 14 is fixedly installed at the end of one side of the positioning disk 11, and a permanent magnet 15 is fixedly installed on the side of the fixing bar 5 close to the fixing belt 1. The iron bar 14 and the permanent magnet 15 are magnetically connected. When adjusting the connecting member 3, the pull block 12 is pulled to make the positioning disk 11 close to the fixing bar 5 until the iron bar 14 and the permanent magnet 15 are against each other. At this time, the iron bar 14 and the permanent magnet 15 are adsorbed, which can simply limit the positioning disk 11 and improve the convenience of use.

[0037] It should be noted here that, with respect to the adsorption range of the iron bar 14 and the permanent magnet 15 , the iron bar 14 and the permanent magnet 15 will generate attraction only when the iron bar 14 approaches the permanent magnet 15 to half of the initial distance.

[0038] See also Figure 1-6 A threaded screw 16 is rotatably provided on one side of the fixing bar 5, and a nut block 17 is threadedly sleeved on the threaded screw 16. The nut block 17 is fixedly connected to the end of the connecting rod 6 away from the thermal pad 7. A servo motor 18 is provided on one side of the fixing bar 5, and the driving end of the servo motor 18 is transmission-connected to one end of the threaded screw 16. A guide groove 19 is provided on one side of the fixing bar 5, and both ends of the threaded screw 16 are rotatably installed in the guide groove 19. The nut block 17 is slidably connected in the guide groove 19, and also includes a limiting member for limiting the sliding direction of the nut block 17. The limiting member includes a guide rod 20, and both ends of the guide rod 20 are fixedly installed in the guide groove 19, and the nut block 17 is slidably sleeved on the guide rod 20.

[0039] In specific implementation, based on the above implementation, by turning on the servo motor 18, the nut block 17 drives the connecting rod 6 and the thermal pad 7 to slide along the direction set by the guide rod 20, and the lateral position of the thermal pad 7 on the fixing belt 1 can be adjusted. The connecting part 3 can be coordinated with the rotation in the slide rail 9 to accurately find the position of the child's bone injury, thereby further improving the heating effect of the traction device.

[0040] A temperature sensor 21 is also provided on one side of the thermal pad 7, and the temperature sensor 21 is electrically connected to the heating block 8. By providing the temperature sensor 21, the heat transferred by the heating block 8 can be detected in real time. When the heating temperature of the heating block 8 exceeds 40 degrees Celsius, the heating block 8 is turned off. When the temperature is lower than 35 degrees Celsius, the heating block 8 is automatically turned on to achieve the effect of temperature control and avoid the problem of poor effect caused by too high or too low temperature.

[0041] It should be noted here that the temperature sensor 21 is a device used to measure the temperature of an object or the environment, and a controller is usually provided inside. The controller is connected to the electrical appliance and is used to receive the signal sent by the temperature sensor 21 to control the switch and operating status of the heating block 8, thereby ensuring that the heating block 8 does not overheat or overcool. Since the temperature sensor 21 and the controller are both existing well-known technologies and are not problems that need to be solved in the background technology of this specification, they will not be explained in detail in this specification.

[0042] Working principle: Before use, the fixing belt 1 needs to be installed on the driving mechanism, which is used to pull the child's legs or feet after fixation to achieve the effect of traction therapy. Since the driving mechanism belongs to the existing technology and is not a problem to be solved in the background technology of this specification, it will not be explained in detail in this specification.

[0043] It should be noted that before use, it is necessary to connect the electrical appliances involved in the traction device, such as the servo motor 18, to an external power source, or install a battery pack in an area of ​​the traction device that does not hinder the operation of other components, and wrap the battery pack with a protective film. The battery pack is then electrically connected to the electrical appliances through a line to power the electrical appliances, thereby ensuring the normal operation of the electrical appliances. Since connecting the electrical appliances to an external power source or installing a battery pack are both existing technologies and are not problems that need to be solved in the background technology of this specification, they will not be explained in detail in this specification.

[0044] When in use, first place the fractured foot or leg of the child on the inner circle of the fixing piece 2, then bend the fixing belt 1 and the fixing piece 2 so that the two ends are against each other, and then adhere the fixing patch 22 to the top of the fixing belt 1 away from the fixing patch 22, so that the child's foot or leg can be fixed and can be conveniently pulled. After the foot and leg are fixed, turn on the heating block 8 to make the electric heating wire in the heating block 8 heat up and transfer the heat to the fixing belt 1, the fixing piece 2 and the child's fracture, so that the heat can promote blood circulation at the fracture site, accelerate metabolism, and thus help the child's bone recovery.

[0045] It should be noted that by pulling the connecting member 3, the connecting member 3 can drive the fixing bar 5 and the heating block 8 to slide along the direction in which the slide rail 9 is set, and the position of the heating block 8 on the fixing belt 1 can be adjusted, so as to actively find the position of the child's bone injury, thereby further improving the heating effect of the traction device; It should be noted here that, after the connector 3 has adjusted its position, the elastic force of the support spring 13 can pull the pull block 12 to move, so that the positioning plate 11 abuts against the fixing belt 1, and the connector 3 can be positioned to avoid the problem of shaking and deflection of the connector 3 during use, thereby improving the stability during use. In addition, when adjusting the connector 3, pulling the pull block 12 can make the positioning plate 11 close to the fixing bar 5 until the iron bar 14 abuts against the permanent magnet 15. At this time, the iron bar 14 and the permanent magnet 15 are adsorbed, and the positioning plate 11 can be simply limited, thereby improving the convenience of use.

[0046] In addition, by turning on the servo motor 18, the nut block 17 drives the connecting rod 6 and the thermal pad 7 to slide along the direction set by the guide rod 20, and the lateral position of the thermal pad 7 on the fixing belt 1 can be adjusted. The connecting part 3 can be coordinated with the rotation in the slide rail 9 to accurately find the location of the child's bone injury, thereby further improving the heating effect of the traction device.

[0047] Finally, by setting a temperature sensor 21, the heat transferred by the heating block 8 can be detected in real time. When the heating temperature of the heating block 8 exceeds 40 degrees Celsius, the heating block 8 is turned off. When the temperature is lower than 35 degrees Celsius, the heating block 8 is automatically turned on to achieve the temperature control effect and avoid the problem of poor effect caused by too high or too low temperature.
