Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, and particularly relates to a traction protection device. Background Technique

[0002] Orthopedics is one of the most common departments in major hospitals. When treating patients, the patient lies on a hospital bed. Existing orthopedic hospital beds are equipped with foldable guardrails or solid boards at the end of the bed for clinical treatment, which can be laid flat. When a traction device is needed to traction the injured part of the patient, in clinical practice, a medical traction rope is usually used in combination with a traction weight or a traction piece for bone traction. In the actual operation of the existing technology, the traction force on the patient's limb cannot be too large. During the traction process, if the traction weight or the traction piece is collided, or the patient's limb moves, it will drive the traction rope, causing the patient to have severe pain, easily resulting in a large traction force on the limb part and causing secondary injury to the patient's limb. Content of the Utility Model

[0003] The purpose of the utility model is to provide a traction protection device to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model is realized by the following technical means:

At the top of the two adjustable telescopic members, a number of interconnected connecting rods are detachably connected. At the top of the two sides, the topmost connecting rods are respectively detachably connected to mounting seats. The two mounting seats are detachably fitted with a support rod. On both sides of the cross bar of the support rod, a first connecting plate and a second connecting plate parallel to the ground are fitted. On the lower surfaces of the first connecting plate and the second connecting plate, a first guide wheel and a second guide wheel are respectively installed. A traction rope is wound around the first guide wheel and the second guide wheel. The two ends of the traction rope are respectively connected to a traction cloth and a counterweight. The counterweight is movably installed on a guide rail mounted on the lower surface of the substrate.

[0006] Compared with the existing technology, the utility model has the following beneficial effects:

[0007] The utility model can fix the substrate on the foldable guardrail or the solid board at the end of the hospital bed, and adjust the relative height of the patient's feet and the traction cloth by adjusting the number of groups of the connecting rods and the telescopic lengths of the two adjustable telescopic members, which is convenient for traction training. Moreover, the counterweight is movably installed on the guide rail, so that the counterweight is not easily shaken by collision, and the pulling force can be avoided acting on the patient's limb.
