Description

lower extremity skin traction device

technical field

The utility model relates to the technical field of medical care, in particular to a device for lower limb skin traction for orthopedic preoperative auxiliary treatment.

Background technique

At present, the lower limb skin traction belt is a commonly used tool in orthopedics. It plays a decisive role in the treatment of lower limb fractures in the elderly. It is very important for preoperative adjuvant therapy of femoral neck and femoral trochanter fractures. At present, the treatment is performed on an orthopedic traction bed. The patient's affected limb is bound on a plastic (nylon) traction belt and placed on a Brown frame or a higher slope pad. The traction rope is directly connected to the nylon traction belt, and the traction rope is placed On the pulley at the end of the traction bed, hang a heavy hammer on the traction rope, use the body weight and the counter-traction force of the heavy hammer to pull the lower limbs, reset the fractured part, maintain the lower limbs in abducted neutral position, relatively fix the fractured part, relax the muscles, and relieve the pain of the affected limb. pain. However, this method of treatment has the following disadvantages:

1. After the traditional lower limb skin traction belt is hung with a heavy hammer for traction, since the traction rope directly pulls both sides of the traction belt, it is easy to deform the traction belt, causing uneven force on each section. In addition, human thighs and calves are proximally thick, The distal end is thin, so that the traction belt is easy to slide down, and finally gathers at the heel. It is easy to cause pressure tissue damage to the entire lower limbs, especially the heel and instep. The slipping of the traction belt can affect the patient's foot ankle pump exercises, foot Functional exercises such as rotational exercise can easily cause deep vein thrombosis of the lower extremities, muscle atrophy, and frequent slipping of the traction belt. Repeated slipping of the traction belt will affect the curative effect and increase the workload of nurses.

2. Because the length and height of the traction frame cannot be adjusted, it cannot be adjusted when the patient feels uncomfortable during the traction process, which leads to more complications caused by the patient's restlessness and uncooperative treatment.

3. For some patients with internal diseases, patients who need to treat internal diseases first and then undergo surgery, there is no orthopedic traction bed in internal medicine, it is difficult to prepare materials for traction, and the traction effect is not in place, which brings inconvenience to patients and nursing work.

Utility model content

The thigh sleeves and calf sleeves The traction rope passes through the movable guide pulley and connects the weight to pull the lower limbs, and the traction sleeve will not slide down and gather at the heel.

2. The utility model is an independent complete set without relying on orthopedic beds. It is simple to prepare and is convenient for use in wards without orthopedic beds. The telescopic frame can be adjusted according to the length of the thigh and calf. Adjust the height, raise the affected limb, the traction pulley can slide left and right, and preserve the neutral functional position of the affected limb abduction.

3. The utility model is equipped with a self-controllable inflatable cushion, through which the air cushion is alternately inflated to massage the lower limbs, increasing the patient's comfort and preventing pressure sores.

4. The utility model is provided with a self-control ankle joint passive trainer, which can passively perform lower limb ankle pump exercises for poorly obeying doctor's orders, especially elderly patients with pain in affected limbs, and can effectively prevent deep vein thrombosis of lower limbs.
