In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.
[0022] In the description of this invention, the term "parallel" refers to two things that are nearly parallel rather than absolutely parallel.
[0023] In orthopedic treatment, pediatric hip casts are commonly used to treat developmental dysplasia of the hip and femoral fractures. These casts provide support for the lower body, facilitating plaster fixation of the hip or femur. However, for the upper body, the lack of hand support necessitates significant effort from medical staff to immobilize the hand. Solutions incorporating hand support are space-consuming, difficult to store post-operatively, and prone to loss.
[0024] Therefore, in order to solve one or more of the above technical problems, refer to Figure 1 and Figure 2 This application provides a pediatric hip joint plaster cast, including a base 100, a main support plate 200, a secondary support plate 300, a limiting member 400, and a support frame 500; the main support plate 200 is provided on the top of the base 100.
[0025] The secondary support plate 300 includes a first secondary support plate 310 and a second secondary support plate 320. The first secondary support plate 310 and the second secondary support plate 320 are respectively disposed at both ends of the main support plate 200 and are rotatably connected to the main support plate 200. The secondary support plate 300 has a folded state and an unfolded state.
[0026] The limiting member 400 includes a first limiting member 401 and a second limiting member 402. The limiting member 400 can be switched to a support position or a non-support position. The limiting member 400 is located at the bottom of the main support plate 200.
[0027] When the secondary support plate 300 is in the folded state, the limiting member 400 is in the non-supported position; when the secondary support plate 300 is in the unfolded state, the limiting member 400 is in the supported position, and the main support plate 200 provides support to the secondary support plate 300 through the limiting member 400, so that the secondary support plate 300 is kept in the unfolded state.
[0028] Continue to refer to Figure 1 and Figure 2 The main support plate 200 and the secondary support plate 300 can be used to provide support for the upper body of the child. The secondary support plate 300 is mainly used to support the child's arms, thus eliminating the need for doctors to use bandages or other items to immobilize the child, thereby reducing the workload of medical staff. In some embodiments, the main support plate 200 can be further configured with a shape that facilitates head support, such as a "convex shape". The main support plate 200 can be further provided with components such as cotton pads and silicone pads. The support frame 500 is mainly used to work in conjunction with the main and secondary support plates to support the child's sacrum and other parts of the body.
[0029] The base 100 primarily serves as the main body to support the main support plate 200, and its structure can vary in different embodiments. In some embodiments, the base 100 includes columns for supporting the main support plate 200 on its top, where "top" refers to one side in the Z direction. The number of columns can be one or more, and in some cases, four.
[0030] In some embodiments, the base 100 and the support frame 500 are connected by a connecting rod 600. One end of the connecting rod 600 is detachably or fixedly connected to the support frame 500, and the other end of the connecting rod 600 is connected to a through hole 110 provided on the base 100. The connecting rod 600 passes through the through hole 110 and slides within the through hole 110, thereby adjusting the relative position of the base 100 and the support frame 500. When the medical staff adjusts it to a position that matches the child's height, the relative position of the connecting rod 600 and the through hole 110 is then limited by the fixing member 120, thereby fixing the position of the base 100 and the support frame 500.
[0031] In some embodiments, the fixing member 120 can be a rotary handle, which can fix the connecting rod 600 by friction. In this case, the relative position of the connecting rod 600 and the slot 110 can be adjusted within a large range. The connecting rod 600 can also be provided with a screw hole to assist the fixing member 120, in which case the connecting rod 600 and the through hole 110 can be in several fixed relative positions.
[0032] In some embodiments, the base 100 and the support frame 500 can also be movably connected by means of a slide rail or the like. In other embodiments, the base 100 is not connected to the support frame 500. The structure at the bottom of the support frame 500 is designed to make it more stable, ensuring that the relative position of the base 100 and the support frame 500 remains unchanged, thereby facilitating the adjustment of the relative position according to the child's condition.
[0033] In some embodiments, reference Figure 1 and Figure 2 The first secondary support plate 310 and the second secondary support plate 320 are respectively disposed at both ends of the main support plate 200, which are the two sides of the main support plate 200 in the X direction. The main support plate 200 and the secondary support plate 300 are rotatably connected, and the rotatable connection can realize the switching between the folded and unfolded states of the secondary support plate. The connection method includes: hinge connection, pivot connection, pin connection, swivel connection, etc. The bottom of the main support plate 200 is provided with a limiting member 400, which includes at least a first limiting member 401 and a second limiting member 402. The first limiting member 401 is disposed on one side of the first secondary support plate 210, and the second limiting member 402 is disposed on one side of the second secondary support plate 220. When the secondary support plate 300 is in the unfolded state, it is parallel to the main support plate 200 to increase the area of the support surface. At this time, the limiting member 400 is in the support position, and the main support plate 200 provides support to the secondary support plate 300 through the limiting member 400. Specifically, the first limiting member 401 supports the first secondary support plate 310, and the second limiting member 402 supports the second secondary support plate 320. The limiting member 400 keeps the secondary support plate 300 in the unfolded state by restricting its descent. When the limiting member 400 is adjusted to a non-support position, the secondary support plate 300 loses the support of the limiting member 400 and can thus fall back to the folded state. When the secondary support plate 400 is in the folded state, its other end connected to the main support plate 200 faces downwards. When using the plaster cast, medical staff can unfold it by rotating the secondary support plate 300 and adjust the limiting piece 400 to the support position to provide arm support for the child. When arm support is not needed, the limiting piece 400 can be adjusted to the non-support position, and the secondary support plate can be adjusted to the folded state to reduce the space occupied by the plaster cast.
[0034] In some embodiments, the pediatric hip joint plaster cast includes a third support plate 700, one end of which is connected to the main support plate 200. The third support plate 700 is narrower in the X direction than the main support plate 200, facilitating treatment and plaster bandaging of the portion of the child lying on the support plate by medical personnel. The third support plate 700 points towards the support frame 500, facilitating its use in conjunction with the support frame 500.
[0035] In some embodiments, the support frame 500 includes a fourth support plate 800, one end of which is connected to the support frame 400. The fourth support plate 800 is narrower in the X direction to facilitate treatment and plaster bandaging of the child by medical personnel. The fourth support plate 800 points towards the main support plate 200 for easy coordination with it. In some embodiments, the support frame 500 contains at least one fourth support plate. The fourth support plate 800 can be rectangular, circular, L-shaped, T-shaped, arc-shaped, etc. In some embodiments, the pediatric hip joint plaster cast also includes a third and a fourth support plate to support the child's torso and hip joint.
[0036] refer to Figure 3 and Figure 4 In some embodiments, the limiting member 400 includes a rotating rod 410, which can adjust its relative position by rotation. When the rotating rod 410 is rotated to the support position, it is at least partially located at the bottom of the sub-support plate 300, thereby providing an upward supporting force to the sub-support plate 300 and keeping it in an unfolded state. When the rotating rod 410 is moved to a non-support position again, it completely disengages from the bottom of the sub-support plate, and the sub-support plate 300 loses the support of the rotating rod 410, thus allowing it to be adjusted to a folded state. The rotating rod 410 can be rectangular, arc-shaped, fan-shaped, or other shapes. In some embodiments, the limiting member 400 may include multiple rotating rods 410 to provide support together and ensure the stability of the sub-support plate 300.
[0037] In some embodiments, the limiting member 400 further includes a rotating seat 420, which is connected to the main support plate 200. A rotating rod 410 is connected to the main support plate 200 via the rotating seat 420, and the rotating rod 410 can rotate around the rotating seat 420 as a pivot, thereby adjusting to a supported position and a non-supported position. In some embodiments, the rotating seat 420 and the main support plate 200 can be integral.
[0038] In some embodiments, the main support plate 200 and the secondary support plate 300 are rotatably connected by a connecting member 900. The limiting member 400 includes a rotating rod 410 and a rotating seat 420. The rotating seat 420 is fixedly disposed on the connecting member 900, and the rotating seat 420 is also used to fix the connecting member 900 to the main support plate 200. This method can effectively save the bottom space of the main support plate 200, and make the space available for the rotating rod 410 larger.
[0039] In some embodiments, the secondary support plate 300 is further provided with a rotation limiting component 430. The rotation limiting component 430 is used to limit the angle of the rotating rod 410, allowing medical personnel to quickly adjust the rotating rod 410 to the optimal rotation angle. Doctors can directly rotate the rotating rod 410 until it abuts against the rotation limiting component 430, placing the rotating rod 410 in the optimal position and preventing the risk of rotating to an angle with poor support when only a single rotating rod 410 exists. In some embodiments, the end of the rotating rod 410 protrudes, and when the secondary support plate 300 is unfolded, the protrusion abuts against the secondary support plate 300 to provide support. In some embodiments, the end of the rotating rod 410 protrudes and has a rotation limiting component 430, which can more effectively enhance its limiting effect by abutting against the protrusion.
[0040] This application embodiment also provides another pediatric hip joint plaster frame, including a base 1100, a main support plate 1200, a secondary support plate 1300, a limiting member 1400, and a support frame 1500; the main support plate 1200 is provided on the top of the base 1100;
[0041] The secondary support plate 1300 includes a first secondary support plate 1310 and a second secondary support plate 1320. The first secondary support plate 1310 and the second secondary support plate 1320 are respectively disposed at both ends of the main support plate 1200 and are rotatably connected to the main support plate 1200. The secondary support plate 1300 has a folded state and an unfolded state.
[0042] The limiting member 1400 includes a first limiting member 1401 and a second limiting member 1402. The limiting member 1400 can be switched to a support position or a non-support position. The limiting member 1300 is disposed at the bottom of the sub-support plate.
[0043] When the secondary support plate is in a folded state, the limiting member 1400 is in a non-supported position; when the secondary support plate is in an unfolded state, the limiting member 1400 is in a supported position, and the main support plate 1200 provides support to the secondary support plate 1300 through the limiting member 1400, so that the secondary support plate 1300 is maintained in an unfolded state.
[0044] By setting the limiting member 1400 at the bottom of the secondary support plate 1300, the design space of the base 1100 at the bottom of the main support plate 1200 can be effectively increased. Furthermore, a rotation limiting block 1430 can be set at the bottom of the main support plate 1200 to improve its reliability.
[0045] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0046] The embodiments of this application have been described in detail above. Specific examples have been used to illustrate the principles and embodiments of this application. The description of the embodiments above is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in specific embodiments and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
