Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a pediatric neck and shoulder misalignment prevention and correction device. Background Technology

[0002] A fracture is a complete or partial break of a bone or bone structure. It is more common in children and the elderly, but also occurs in young and middle-aged adults. Patients usually have a fracture in one location, but a few have multiple fractures. With timely and appropriate treatment, most patients can recover their original function, while a few may have varying degrees of sequelae. Pediatrics is a comprehensive medical science that studies the physical and mental development, health care, and disease prevention of children. All health and hygiene issues involving children and adolescents fall under the scope of pediatrics, and its patients are in the growth and development period.

[0003] When children suffer neck and shoulder fractures, cervical braces are typically used to immobilize the neck and shoulders, preventing further injury due to movement and potential displacement of the fracture site. However, most of these braces require full skin contact to stabilize the head and cervical spine. When children are resting in bed with the brace on, the prolonged pressure between the neck and the brace can cause itching, leading children to shake their heads to relieve discomfort and potentially causing further displacement of the fracture, resulting in secondary injury. Therefore, we propose a pediatric cervical and shoulder dislocation prevention and correction device. Summary of the Invention

The inner wall of the sealing box is provided with a pusher that can alternately push connecting plates 1 and 2 to slide along the inner wall of the sealing box.

[0007] Preferably, the pushing component includes a connecting post one fixedly connected to one end of a connecting plate two, a connecting hole two slidably connected to the connecting post one on the inner wall of the connecting plate two, a connecting post two fixedly connected to one end of the connecting plate two, and a connecting plate three fixedly connected to one end of each of the connecting posts one and two, the connecting plate three being slidably connected to the inner wall of the sealing box. Return springs are fixedly connected to both ends of the connecting plate three, one end of each return spring being fixedly connected to the inner wall of the sealing box. A trapezoidal block is fixedly connected to one end of the connecting plate three, a movable plate is provided on the outer side of the trapezoidal block, a movable rail is fixedly connected to the inner wall of the sealing box and slidably connected to the movable plate, multiple pressing blocks are fixedly connected to the side of the movable plate near the trapezoidal block, and a driving component is provided on the side of the movable plate away from the pressing blocks, capable of pushing the movable plate to slide along the inner wall of the movable rail.

[0008] Preferably, the driving component includes a transmission rack fixedly connected to one end of the movable plate, a transmission gear meshing on the outer side of the transmission rack, and limiting components at both ends of the transmission rack that can limit the transmission gear. A transmission rod is fixedly connected to the center of the transmission gear, and both ends of the transmission rod are rotatably connected to the inner wall of the sealing box. A transmission impeller is fixedly connected to the outer side of one end of the transmission rod, and air ducts are provided on both sides of the transmission impeller. One end of the air duct is fixedly connected to the inner wall of the sealing box, and a venting component is provided on the outer side of the sealing box that can vent air to the air duct. An exhaust pipe is connected to the outer side of the sealing box.

[0009] Preferably, the limiting component includes limiting blocks that are fixedly connected to both sides of one end of the transmission rack, a limiting rod that is fixedly connected to one end of the limiting block, a sliding block that is slidably connected to the outside of the limiting rod, a limiting tooth that is fixedly connected between the two sliding blocks, and a compression spring that is fixedly connected to one end of the sliding block, with one end of the compression spring fixedly connected to the limiting block.

[0015] This invention has at least the following beneficial effects:

[0016] In use, this application utilizes a neck brace and restraint straps to securely restrain and fix the neck and shoulders of a child patient. Furthermore, the support mechanism alternately supports the child's neck while the patient is lying down. In contrast, existing technologies often cause itching due to prolonged pressure between the neck skin and the neck brace while the child is resting in bed, leading to head shaking to relieve discomfort and potentially causing dislocation of the fracture and secondary injury. This application addresses this issue by using restraint straps to assist in the neck brace's function when the patient has a neck fracture. The main body stabilizes the neck, and in the event of a shoulder fracture, the shoulder can be bound with a restraint strap and further stabilized by the neck brace. This prevents the binding position from changing and causing misalignment of the fracture while the child is resting in bed. The support mechanism alternately supports the child's neck at intervals while the patient is in bed, thus preventing the patient's skin from being in constant contact with the neck brace surface. This avoids itching caused by pressure on the skin, which could lead to head and neck movement. Furthermore, when the patient feels uncomfortable and tends to move their neck, the support mechanism automatically switches the support position for the child's neck, improving the patient's comfort while in bed.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1

[0028] Please see Figure 1-6This invention provides a technical solution: a pediatric neck and shoulder dislocation prevention and correction device, comprising a neck brace body 1; a restraint strap 2, the restraint strap 2 being fixedly connected to the lower part of the neck brace body 1; a fixing frame 3, the fixing frame 3 being fixedly connected to the outer side of the neck brace body 1; and a support mechanism 4, located on the inner wall of the fixing frame 3. The support mechanism 4 can alternately support the child's neck when the child is lying down. In use, the neck is fixed by the neck brace body 1, and the patient's shoulders are bound by the restraint strap 2. The restraint strap 2 can assist the neck brace body 1 in fixing the neck in the event of a neck fracture. When a patient suffers a shoulder fracture, the restraint strap 2 can be used to bind the shoulder and the neck brace body 1 can be used for additional fixation. This prevents the binding position from changing and causing the fracture position to shift when the child is resting in bed. The support mechanism 4 can alternately support the child's neck at intervals when the patient is lying in bed, thereby preventing the patient's skin from being in constant contact with the surface of the neck brace body 1. This would prevent the skin from becoming itchy due to pressure, which could cause the child's head and neck to shake. Moreover, when the patient feels uncomfortable and tends to shake their neck, the support mechanism 4 can automatically switch the support position for the child's neck, improving the patient's comfort when lying in bed.

[0029] Support mechanism 4 includes a sealing box 40 fixedly connected to the inner wall of the fixed frame 3. The sealing box 40 is made of sound-insulating material to avoid disturbing the patient's rest. Multiple connecting rods 1 41 and connecting rod 2 42 are located on the inner wall of the sealing box 40. The connecting rods 1 41 and connecting rod 2 42 are alternately distributed to support the patient's skin. Silicone pads 43 are fixedly connected to the ends of the connecting rods 1 41 and connecting rod 2 42 near the patient's skin. Connecting plates 1 44 are fixedly connected to the ends of the multiple connecting rods 1 41 away from the silicone pads 43. Connecting plates 1 44 are slidably connected to the inner wall of the sealing box 40. Multiple communicating holes 1 45 are provided on the inner wall of the connecting plates 1 44 that can slidably connect with the connecting rods 2 42. Connecting plates 2 46 are fixedly connected to the ends of the multiple connecting rods 2 42 away from the silicone pads 43. Connecting plates 2 46 are slidably connected to the inner wall of the sealing box 40. The inner wall of the sealing box 40 is provided with a mechanism that can alternately push the connecting plates 1 44 and connecting plates 45. When the supporting mechanism 4 is working, if the pusher 47 pushes the connecting plate 44 to move closer to the patient's neck along the inner wall of the sealing box 40, then the connecting plate 46 moves away from the patient's neck along the inner wall of the sealing box 40. The connecting plate 44 drives the connecting rod 41 to push the silicone pad 43 to fit against the patient's skin to support the patient's neck. The connecting plate 46 also drives the connecting rod 42 away from the patient's skin. After the silicone pad 43 at the end of the connecting rod 41 has been in contact with the patient's skin for a period of time, the pusher 47 pushes the connecting plate 46 to move closer to the patient's neck along the inner wall of the sealing box 40, while the connecting plate 44 moves away from the patient's neck along the inner wall of the sealing box 40. This completes the change of the support position for the patient's neck, avoiding constant pressure on the patient's neck skin and improving the comfort of children lying in bed.

[0030] The pusher 47 includes a connecting post 48 fixedly connected to one end of a connecting plate 44. A connecting hole 49, slidably connected to the connecting post 48, is provided on the inner wall of the connecting plate 46. A connecting post 410 is fixedly connected to one end of the connecting plate 46. A connecting plate 411 is fixedly connected to one end of both the connecting post 48 and the connecting post 410. The connecting plate 411 is slidably connected to the inner wall of the sealing box 40. Return springs 412 are fixedly connected to both ends of the connecting plate 411. One end of each return spring 412 is fixedly connected to the inner wall of the sealing box 40. A trapezoidal block 413 is fixedly connected to one end of the connecting plate 411. A moving plate 414 is located outside the trapezoidal block 413. A moving rail 415, slidably connected to the moving plate 414, is fixedly connected to the inner wall of the sealing box 40. Multiple pressing blocks 416 are fixedly connected to the side of the moving plate 414 closest to the trapezoidal block 413. The pressing blocks 416 are close to the trapezoidal block 413. 3. One side is provided with an inclined end 436 to cooperate in squeezing the inclined side of the trapezoidal block 413. The moving plate 414 is provided with a driving member 417 on the side away from the squeezing block 416, which can push the moving plate 414 to slide along the inner wall of the moving rail 415. When the driving member 47 is working, if the initial connecting rod 41 pushes the silicone pad 43 to fit against the patient's neck skin, the driving member 417 drives the moving plate 414 to slide along the inner wall of the moving rail 415. When the moving plate 414 just moves, the moving plate 414 drives the squeezing block 413 to slide along the inner wall of the moving rail 415. When block 416 moves, the inclined end 436 of the compression block 416 compresses the inclined side of the trapezoidal block 413, thereby pushing the connecting plate three 411 to move. The connecting plate three 411 stretches the return spring 412, and the connecting plate three 411 pushes the connecting post two 410 connected to it to move. The connecting post two 410 pushes the connecting plate two 46 to move so as to push the silicone pad 43 at the end of the connecting rod two 42 to fit against the patient's skin. Meanwhile, the silicone pad 43 at the end of the connecting rod one 41 is still in contact with the patient's skin. As the moving plate 414 moves, a compression plate separates from the trapezoidal block 413. The return spring 412, which is in a stretched state, drives the connecting plate three 411 to move. The connecting plate three 411 drives the connecting post one 48 to move. The connecting post one 48 drives the connecting plate one 44 to move, thereby separating the silicone pad 43 at the end of the connecting rod one 41 from the patient's skin. This completes the change of the support position for the patient's neck skin, avoiding discomfort caused by constant pressure on the skin of children when they are lying in bed.

[0031] The driving component 417 includes a transmission rack 418 fixedly connected to one end of the moving plate 414. A transmission gear 419 meshes with the outer side of the transmission rack 418. Limiting members 420 capable of limiting the transmission gear 419 are respectively provided at both ends of the transmission rack 418. A transmission rod 421 is fixedly connected to the center of the transmission gear 419. Both ends of the transmission rod 421 are rotatably connected to the inner wall of the sealing box 40. A transmission impeller 422 is fixedly connected to the outer side of one end of the transmission rod 421. Both sides of the fan blades are provided with concave arcs to cooperate with the airflow to drive the transmission impeller 422 to rotate. Air ducts 423 are located on both sides of the transmission impeller 422. One end of each air duct 423 is fixedly connected to the inner wall of the sealing box 40. The outer side of the sealing box 40 is provided with a venting element 424 that allows air to pass through the air ducts 423. An exhaust pipe 425 is connected to the outer side of the sealing box 40. When the drive unit 417 is working, the venting element 424 injects air into either air duct 423, and the airflow is blown towards the transmission impeller 422 through the air ducts 423. 22. The transmission impeller 422 drives the transmission rod 421 to rotate, the transmission rod 421 drives the transmission gear 419 to rotate, and the transmission gear 419 drives the transmission rack 418 to move in coordination with the moving plate 414 to slide along the surface of the moving rail 415. The position of the transmission rack 418 can be limited by the set limiting member 420. The airflow injected into the sealing box 40 is discharged through the exhaust pipe 425 to avoid excessive air pressure in the sealing box 40. The sealing box 40 is made of sound insulation material to prevent the sound emitted during ventilation from disturbing the patient's rest. When the ventilation component 424 injects air into the remaining air duct 423, the air duct 423 on the other side pushes the transmission impeller 422 to rotate in the opposite direction. The transmission impeller 422 drives the transmission rod 421 to rotate in the opposite direction, and the transmission rod 421 drives the transmission gear 419 to rotate in the opposite direction in coordination with the transmission rack 418 to drive the moving plate 414 to rotate in the opposite direction along the inner wall of the moving rail 415, so as to facilitate the change of the support position for the patient's neck skin.

[0032] The limiting component 420 includes limiting blocks 426 fixedly connected to both sides of one end of the transmission rack 418. A limiting rod 427 is fixedly connected to one end of each limiting block 426. A sliding block 428 is slidably connected to the outer side of the limiting rod 427. A limiting tooth 429 is fixedly connected between the two sliding blocks 428. A compression spring 430 is fixedly connected to one end of each sliding block 428. One end of the compression spring 430 is fixedly connected to the limiting block 426. When the limiting component 420 is working, when the transmission gear 419 rotates, it drives the transmission rack 418 to move. When the limiting tooth 429 moves to the position of the transmission gear 419, the transmission gear 419 moves the limiting tooth 429, which in turn moves the sliding block 428. 8. Slide along the surface of the limiting rod 427 and compress the compression spring 430. When the tooth of the transmission gear 419 separates from the limiting tooth 429, the compression spring 430, which is in a compressed state, pushes the sliding block 428 to reset. The sliding block 428 drives the limiting tooth 429 to reset. The limiting tooth 429 resets to engage with the next tooth of the transmission gear 419. When the transmission gear 419 reverses, the transmission gear 419 engages with the limiting tooth 429. The limiting tooth 429 drives the limiting rod 427 to move. The limiting rod 427 drives the transmission rack 418 to move so that the teeth on the surface of the transmission rack 418 engage with the transmission gear 419, thereby changing the direction of movement of the transmission rack 418.

[0033] The ventilation component 424 includes ventilation pipes 431 fixedly connected to both ends of the sealing box 40. The two ventilation pipes 431 are respectively connected to an air intake pipe 423. A three-way solenoid valve 432 is fixedly connected to one end of each ventilation pipe 431. Pressure sensors 435, capable of controlling the switching of the three-way solenoid valve 432, are fixedly connected to the side walls of both sides of the neck brace body 1. The three-way solenoid valve 432 is fixedly connected to the sealing box 40. One end of the three-way solenoid valve 432 is connected to an air inlet pipe 433, and one end of the air inlet pipe 433 is connected to an air pump 434. When the ventilation component 424 is working, the air pump 434 injects airflow into the air inlet pipe 433. When the patient experiences discomfort and tends to turn their neck... When the pressure on the pressure sensor 435 on the side wall of the neck brace body 1 increases, the pressure sensor 435 controls the three-way solenoid valve 432 to work. The three-way solenoid valve 432 changes the airflow direction, thereby switching the airflow into different ventilation pipes 431. The airflow is injected into the air duct 423 through the ventilation pipe 431 to cooperate with changing the rotation direction of the transmission impeller 422. If the patient's head does not move, the three-way solenoid valve 432 will automatically switch the connection direction at intervals to allow the neck support position to be changed at intervals when using it for children, so as to avoid neck skin discomfort when children are lying down and improve patient comfort.

[0034] Example 2

[0035] like Figure 7-8In this second embodiment, the other structures remain unchanged. The difference from the first embodiment is that the sealing box 40 is slidably connected to the fixing frame 3. A positioning element 5 is provided between the sealing box 40 and the fixing frame 3 to fix the sealing box 40. The positioning element 5 includes a positioning post 50 that is slidably connected to the inner wall of the sealing box 40. One end of the positioning post 50 is fixedly connected to a compression spring 51. The end of the compression spring 430 is fixedly connected to the inner wall of the sealing box 40. The inner wall of the fixing frame 3 is provided with a positioning hole 52 that can engage with the positioning post 50. A top block 53 is slidably connected to the inner wall of the positioning hole 52. One end of the top block 53 protrudes from the inner wall of the positioning hole 52 and communicates with the outside. When the patient is able to get out of bed for exercise, the staff presses the top block 53. The top block 53 slides along the inner wall of the positioning hole 52 and pushes the positioning post 50 out of the inner wall of the positioning hole 52. The positioning post 50 compresses the compression spring 51, thereby releasing the engagement between the positioning post 50 and the positioning hole 52, so that the staff can take the sealing box 40 out of the fixing frame 3 for the user to walk and exercise.
