TECHNICAL FIELD

[0001] The utility model relates to human body correction auxiliary device field, concretely relates to a wearable device that relieves head forward bending. BACKGROUND

[0002] Head forward bending is a human body pathological state, and is common in Parkinson's disease or Parkinson's syndrome patients, neck physiological curvature change people, middle-aged and old people with osteoporosis, people who work for a long time in a crouched position, and even includes teenagers who are addicted to mobile phones for a long time, and these people constitute so-called "bend head tribe". With the growth of age, head forward bending phenomenon will become more and more serious, and can involve the forward bending of the spine, forming a humpback. At present, the head forward bending is mostly corrected by using conservative methods and various orthopedic fixators. The most common solution is to use a neck brace, and a support pad is added between the chin and the chest and clavicle to prevent head forward bending and drooping. The disadvantage of this solution is that not only the opening and closing of the chin are limited, affecting the mouth opening, speaking, eating, chewing, and the left and right rotation of the head is also limited.

[0025] Compared with the prior art, the embodiments of the present application have the following advantages and beneficial effects:

[0026] 1. The utility model discloses a headband for horizontal pulling of the forehead, relieving the patient's head from forward bending and drooping, and realizing neck correction. The force point of this mode is on the forehead. Compared with the correction device in the prior art that exerts force upward on the chin, the utility model embodiment generates greater force and torque, and has higher correction efficiency, while not affecting the normal activities of the patient's mouth opening and occlusion. That is, the utility model embodiment uses the lever principle of statics, takes the human back as the supporting point, tightens the waistband as the driving force, uses the lever effect of the force transmission plate to make the headband generate horizontal force for pulling the forehead backward, to relieve the head from forward bending and the tendency of bending over. The force point of the device is on the forehead, and the activities of the head and the five senses are not limited. In the existing correction device, the force is exerted upward on the chin, which will affect a series of actions such as mouth opening, speaking, eating and chewing. The working principle is clear and reliable.

[0027] 2. The human head is supported at the end of the cervical spine, and its forward inclination and backward inclination are around a physiological center line. Relative to the physiological center line, the force vertically upward on the chin and the force horizontally backward on the forehead will generate an effective torque (hereinafter referred to as the counteracting torque) against the head forward inclination. With the same driving force, the force arm is longer when the force point is on the forehead than when the force point is on the chin, and the counteracting torque is greater. The lever effect can amplify the horizontal force to some extent, and further increase the counteracting torque.

[0028] 3. The wearable device for relieving head forward bending provided by the utility model embodiment includes a force transmission plate, which is bent inward at both ends, so that the longitudinal geometric shape of the force transmission plate is close to the contour of the human back, which is conducive to being worn on the inner layer of clothes. The device is arranged above the waist or hips, and will not affect the patient's daily activities such as walking and sitting.

[0029] 4. The force transmission plate of the utility model embodiment includes an upper plate, a middle plate and a lower plate. The connection between the upper plate and the lower plate and the middle plate is detachable, and multiple specifications can be designed and manufactured according to different body types of users, with strong pertinence and flexibility.

[0030] 5. The utility model embodiment provides a roller assembly on the outer side of the upper plate, which is movably connected with the headband. When the wearer rotates the head left and right, the sliding friction between the headband and the force transmission plate will be converted into rolling friction between the rollers and the roller supporting rods, which can reduce the resistance of the head rotation and increase the wearing comfort.
