Spine traction wheelchair easy to adjust
Technical Field
The utility model relates to the field of medical equipment, in particular to a spine traction wheelchair easy to adjust.
Background
Scoliosis, commonly referred to as scoliosis, is a three-dimensional deformity of the spine that includes sequence abnormalities in the coronal, sagittal, and axial positions. Mild scoliosis is usually without significant discomfort and no apparent somatic deformity in appearance. A severe scoliosis may affect the growth and development of infants and teenagers, deform the body, and severely affect the cardio-pulmonary function and even involve the spinal cord, resulting in paralysis. Severe scoliosis requires surgical treatment and, prior to surgery, traction. Traction is a common treatment method in orthopedics department, which applies the principle of acting force and reacting force to resist the tension and retraction of soft tissues, so that the fracture and dislocation become restitution, and deformity is prevented and corrected. The traction treatment is carried out for a period of time, so that the lung capacity of a scoliosis patient can be improved, the Cobb angle of the scoliosis is reduced, the risk of severe scoliosis is reduced, and the flexibility of the spine is increased so as to improve the curative effect and the success rate of scoliosis orthopedic surgery. However, the current traction apparatus has the following problems: after the horizontal traction equipment is used for long-time traction, the patient can feel uncomfortable, contact skin allergy and the like, and needs to take a spinal traction wheelchair for movement.
But the existing spine traction wheelchair arranges the counterweight structure behind the backrest of the wheelchair, so that the adjustment of the counterweight is very troublesome and inconvenient, and the arrangement in the middle part is not favorable for patients with different lateral curvatures to use.

Just so can make the balancing weight install in the side, can be better when can pulling patient, it is also very convenient to adjust the weight of balancing weight, and patient oneself also can operate under the condition that does not have other people's help.
Preferably, the support rod comprises a 7-shaped main rod and an auxiliary rod sleeved on the horizontal part of the main rod, and the cross rod is fixed on the end parts of the 2 auxiliary rods.
Preferably, a plurality of pin holes are formed at the horizontal portion of the main rod, and the sub-rod is fixed to the horizontal portion of the main rod by a pin shaft. Thus, the position of the cross bar can be adjusted to avoid the traction from deflecting.
Preferably, a reinforcing rod is further arranged between the vertical parts of the 2 main rods.
Preferably, the wheelchair seat is also formed with armrests on both sides of the wheelchair backrest.
Preferably, 2 counter weight fixing frames are respectively and fixedly installed at two sides of the chair seat of the wheelchair, which are formed with the armrests. Therefore, the utility model is suitable for scoliosis patients of different types, and doctors can select the balancing weight to place in the balancing weight fixing frame on one side of the patient according to the scoliosis direction.
Preferably, the guide wheel is also provided with a brake, and the brake comprises a pedal brake and a hand brake. Therefore, the brake can be controlled by the pushing personnel through the hand brake, and the brake can be controlled by the foot of the patient, so that the hidden danger that the pushing personnel cannot brake in time after leaving due to the accident is avoided.
Preferably, a handle is fixedly arranged on one side of the armrest far away from the wheelchair backrest, and a hand brake is fixedly arranged on the handle.
Preferably, the length of the cross bar is greater than the spacing between 2 handrails. Therefore, the pulley fixing seats at the two ends of the cross rod can be just positioned right above the counterweight fixing frame, and the traction force is further prevented from inclining.
Preferably, the balancing weight adjusting rod is a threaded rod and is in threaded fit with the balancing weight. Just so can adjust the weight that the balancing weight just can be adjusted through rotatory balancing weight regulation pole, further simplify the operation, facilitate the use.
The utility model discloses an overcome prior art not enough, designed the backbone of easily adjusting and pull wheelchair, the counterweight block is installed at the side promptly, can be better when pulling patient, it is also very convenient to adjust the weight of counterweight block, patient oneself also can operate under the condition that does not have other people's help, be applicable to the scoliosis patient of different grade type moreover, the doctor can select the counterweight block to place in the counterweight block mount of one side wherein according to the direction of patient's scoliosis.
