Forcing device of cervical vertebra tractor

Abstract

Provided is a forcing device of a cervical vertebra tractor. The forcing device is connected with one end of the tractor. The forcing device comprises an air compressor and a cylinder. The air compressor is connected with an air inlet end of the cylinder through an air inlet pipeline. A one-way valve is arranged at the end, close to the air compressor, on the air inlet pipeline. The portion, located between the one-way valve and the air inlet end of the cylinder, of the air inlet pipeline is provided with an electromagnetic reversing valve and a pressure sensor used for detecting air pressure in the air inlet pipeline. The output end of the pressure sensor is connected with a controller and feeds back a detected pressure signal to the controller. The controller is provided with two control circuits. One control circuit is connected with the electromagnetic reversing valve, and the other control circuit is connected with the air compressor. A piston rod of the cylinder is connected with a traction line. The traction line is connected with the tractor through a guide wheel. Various treatment modes such as continuous traction and intermittent traction are selected according to specific conditions of patients. The change process of traction force can be freely designed. The forcing device has the auxiliary functions of traction force automatic compensation, automatic timing, excessive traction force or out-of-control protection and the like.

Description

technical field [0001] The invention relates to a cervical vertebra tractor, in particular to a force applying device of the cervical vertebra tractor. Background technique [0002] Cervical traction, as one of the main non-surgical treatments for cervical diseases, has a long history and is often used as the first choice or main treatment because of its definite curative effect. Traction therapy is widely used for its simplicity, safety, painlessness and effectiveness. [0003] At present, a large number of mechanical bedside tractors are used in hospitals. Although this tractor has the advantages of simple structure, low price, and small space occupation, it also has the following disadvantages: ①The change of the traction force is manually performed by medical staff. It is achieved by increasing or decreasing the weight of the weight, so the accuracy of the force is poor; ②The traction force is applied or removed suddenly, which will cause discomfort in the cervical spin...
