Abstract: A lumbar traction device includes a tabular base, an indentation, a lumbar tracking base, tightening pieces, a weight member, a driving member and a controller. The lumbar tracking device allows the user to grip the controller to control the rotation of the rotation axis, and drive the threaded rod to rotate spirally forward and backward so as to synchronously drive the lumbar tracking base to move forward and backward for stretching or releasing. Hence, the user can independently operate the lumbar traction device for optimal applicability and safety. The weight member is further provided with a weight adjustment component to adjust the weight levels required by the user for lumbar traction. A warning part emit warning signals to inform the user that the preset weight value is reached, helping to avoid discomfort or secondary injuries resulting from overload.

Abstract: A body hauling mechanism includes a weight seat, a weight control assembly and a body hauling auxiliary part. The weight control assembly of the body hauling mechanism has an enclosure with a stretching mechanism configured inside. Said stretching mechanism is made up of a separating board, a gear unit, a cord rolling wheel, a back-stop mechanism and a driving wheel. The user can pull the two-way pulling cord to drive the stretching mechanism to control the weight control assembly hanged on the weight seat, so that the hauling cord of the weight control assembly can be retracted or released mildly, and can apply or release the hauling force smoothly. When using the body hauling mechanism to improve the symptoms caused by irritation or compression of the body nerves, secondary injury of the affected part can be avoided.

Abstract: The present invention provides a cervical traction mechanism having a weight seat used to provide the weight force required for cervical traction. A weight adjustor is used to preset a weight force required for cervical traction as a sign of alarming. A pulling brake unit includes a pulley assembly, stay cord and traction belt joint, with one end of said pulley assembly linked to the brake unit connection end of the weight seat. A cervical traction belt has one end linked to the traction belt joint of the pulling brake unit. An alarming portion is set onto a preset location of the weight seat. When the spring weight of the weight seat reaches the weight force set by the operator, a signal is sent by the alarming portion. The cervical traction mechanism improves safety and applicability and makes it possible to avoid misoperation and recurrent damage to the patients.
