Seated cervical traction device and angle sensing method capable of making proper adjustment in time to make sure exactly the traction angle of the seated cervical traction device relative to a patient
A seated cervical traction device and an angle sensing method are disclosed, the device includes a pulling module, a suspension element, a traction element, and a sensing module. The suspension element is arranged at one side of the pulling module one end of the traction element is connected to the pulling module while the other end hanging down through one end of the suspension element the sensing module is arranged at the part of traction element that hangs down through one side of the suspension element. When the traction element is stretched, an angle which takes one end of the suspension element hanging downwardly and perpendicularly to a horizontal plane is used as a standard reference, and with the angle that is perpendicular to a horizontal plane as the standard reference, a traction angle is formed and detected by the sensing module. Therefore, an operator is able to make sure exactly the traction angle of the seated cervical traction device relative to a patient, thereby enabling a proper adjustment to be made in time.本發明有關於一種坐式頸椎牽引裝置及其角度感測方法,其包含一拉力模組、一懸掛件、一牽引件與一感測模組。該懸掛件設置於該拉力模組之一側。該牽引件一端連接該拉力模組,其另一端經該懸掛件之一端而向下垂掛。該感測模組設置於經該懸掛件之一端而向下垂掛之該牽引件的部分。當牽引該牽引件,以該懸掛件之一端點向下延伸並垂直於水平面之角度為基準,並依據垂直於水平面之角度為基準,而形成一牽引角度,該感測模組偵測該牽引角度。如此操作者可明確得知坐式頸椎牽引裝置相對於使用者之牽引角度,而適時的作出相對應的調整。1‧‧‧坐式頸椎牽引裝置10‧‧‧拉力模組100‧‧‧座椅101‧‧‧椅背20‧‧‧懸掛件21‧‧‧桿件23‧‧‧輪軸30‧‧‧牽引件31‧‧‧牽引頭戴33‧‧‧牽引件40‧‧‧感測模組
