Description

Technical Field

[0001] The utility model relates to the technical field of fixing devices, in particular to a leg fixing device. Background Art

[0002] When a person suffers a knee injury or a leg fracture, the leg needs to be fixed to prevent the person's movement from causing secondary injury to the leg. Currently, this is usually done with a splint or plaster.

[0003] However, the angle of the splint and the gypsum board cannot be adjusted after being fixed, so the angle cannot be adjusted according to the recovery condition of the person, which is inconvenient to use. Therefore, we propose a leg fixing device to solve the above problem. Utility Model Content

[0015] The limit plate can be limited to prevent the limit plate from rotating, so that the limit plate can rotate with the rotation of the rotating rod, and then after the limit block is embedded in the connecting plate, the rotating rod cannot be driven to rotate, so that the limit plate can complete the limit fixation.

[0016] Preferably, a pneumatic fixing bag is arranged inside the annular shape formed by the first mounting ring and the second mounting ring, an opening is arranged at the end of the pneumatic fixing bag, and the position of the opening is adapted to the opening of the first mounting ring and the second mounting ring;

[0017] The first mounting ring and the second mounting ring can be made more comfortable after being sleeved on the patient's legs, and the covering effect on the patient's legs can be better, thereby avoiding the first mounting ring and the second mounting ring from loosening from the patient's legs.

[0018] Preferably, an air nozzle is inserted at the end of the first mounting ring, and the air nozzle is connected to the inside of the air pressure fixing bag;

[0019] The air nozzle can be inflated by an air pump from the outside, so that the gas inside the air pressure fixation bag can be changed, and the squeezing force of the air pressure fixation bag on the patient can be changed. The air pressure fixation bag can be used to fix the patient according to different thicknesses.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 2. The utility model can make the connecting plate drive the rotating shaft seat to rotate during the rotation process, and the rotating shaft seat drives the rotating rod and the limiting plate to rotate. When the limiting plate drives the limiting insert to be embedded into the limiting insert hole, the angle between the two sets of connecting plates is fixed to avoid loosening after fixation, so that the fixing effect is better.
