Problems solved by technology

In the process of applying external force, the following two problems will arise. One is that the resistance of each patient is different, and the critical point is also different. Therefore, the amount of external force applied by the doctor is uncertain. If the external force is too small, it will not be effective. To achieve the therapeutic effect, excessive external force will cause new damage to the patient and increase the pain of the patient; second, when the doctor gradually increases the external force, the muscle contraction and resistance of the patient due to fear are proportional to the external force. The patient's sense of fear is accompanied by traction from beginning to end, which increases the difficulty of treatment

Embodiment 1

[0009] Embodiment 1: The driving mechanism is a hydraulic lever type traction bed

[0010] see figure 1 , the bed surface is composed of two sliding bed boards 3, the sliding bed boards are set in the slideway of the bedside frame, so that the sliding bedboard can slide in the slideway, and the bed surface is provided with a sling frame 1 and a foot stand 2, which are used for positioning the patient, The fulcrum structure that is provided with under the bed surface is that the bed surface is installed on the supporting seat 6 through the hinge 9 . The mechanism that drives the bed surface to rotate around the axis is a hydraulic jack 8, which is placed under the bed surface, the jack pressure bar 7, the connecting rod 5 and the hand wheel 4 are hinged in turn, and the hand wheel is arranged on the support seat. The patient lies flat on the bed, uses the sling to position the patient, turns the hand wheel back and forth, drives the jack pressure rod, and the jack rotates the ...

Embodiment 2

[0012] Embodiment 2: The driving mechanism is a lever-type traction bed with four linkages

[0013] see figure 2 , the mechanism that drives the bed surface to rotate around the axis can also be a four-bar linkage mechanism, that is, the support bed surface and two connecting rods 13, 14 form a four-bar linkage mechanism, and its output point is composed of a screw 11 and a screw nut 12. The bevel gear of the lead screw meshes with the gear in the handwheel, drives the handwheel, the lead screw rotates, the screw nut moves, and drives the bed surface to rotate around the fulcrum. Others are the same as in Embodiment 1.

Abstract

The present invention provides a lever-type traction table. It is characterized by that under the table surface a fulcrum is set, both are formed into the lever structure. Said invention utilizes the gravity of patient's self-body to make traction treatment.

Description

technical field [0001] The invention relates to a medical device for traction, in particular to a traction bed. Background technique [0002] Lumbar disc herniation, facet joint disorder, lumbar strain and hyperosteogeny are frequently-occurring diseases of middle-aged and elderly people. Using traction to treat the disease has the characteristics of non-invasiveness, small side effects, and remarkable curative effect. It is currently the preferred treatment method. The equipment used in this method is a traction bed, and the traction bed surface is made up of several sliding bed boards, and the patient lies flat and is fixed on the traction bed, and external force (including manpower and electric power) is used to draw the patient. When an external force is applied to the patient, out of the instinct of fear, a resistance force opposite to the traction force will be generated in the patient's body to counteract the external force. Only when the external force is greater t...
