Description

A device for maintaining the normal physiological curvature of the spine

technical field

The utility model relates to an orthopedic appliance for non-surgical treatment, in particular to a device for maintaining the normal physiological curvature of the spine.

Background technique

As we all know, the human spine consists of 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 1 sacral vertebra and 1 coccygeal vertebra. Each vertebra is connected by cartilage, intervertebral disc, ligament, muscle and other tissues. In the middle, the spine is like a large spring, which has the function of buffering pressure, shock absorption, and protecting the brain and internal organs. The human spine has 4 physiological curvatures, which are used to protect the head and stabilize the position of the internal organs of the human body, reduce the impact caused by movement, and have a buffering effect. If you stay in a bad posture for a long time, it will lead to changes in the physiological curvature, which will cause a series of clinical symptoms, such as: changes in the structure of the intervertebral disc, dislocation of the small joints, soreness and pain in the neck and waist, dizziness, neck-type hypertension, upper limb pain and numbness, and lower limb pain Numbness, etc. To maintain the normal physiological curvature of the spine, there must be a comfortable cushion or seat. When a person is in a sitting position, the cushion and seat should fully fit the four curvature positions of the human spine, rather than being suspended, and the supporting material must be There is a certain intensity and arc. However, at present, the appearance and structure of seats on vehicles such as airplanes, trains, and automobiles basically do not conform to the physiological curvature structure of the human spine, and there is no suitable cushion. When people ride these vehicles, the physiological curvature of their spines is basically in the air or not in the correct position. Relevant literature records: When the human spine deviates from the central axis by more than 10 degrees, it is called scoliosis. The spine needs to bear a pressure equivalent to 1.5 times body weight when sitting, and it is equivalent to 2.5 times body weight pressure when sitting forward. When sitting, the lumbar intervertebral disc pressure is 150%. The disc pressure is 250% when the body is leaning forward in the sitting position. Therefore, if such seats and cushions are used for a long time, the physiological curvature of the spine cannot be in the normal anatomical position, resulting in cervical and lumbar spine diseases.

In the Chinese patent database, the patent applications related to spinal curvature correction include CN1539354 "Spine Health Chair", CN101244001 Spinal Correction Fixer, CN206138248U "Spine Balance Health Apparatus", CN202184828U "Spine Correction Auxiliary", CN106726052A "A Synchronous Implementing Device for Scoliosis Correction and Lumbar Curvature Adjustment", CN108742974A "Universal Kyphosis Orthosis", CN109730820A "A Insert Type Scoliosis Orthosis with Adjustable Correction Degree", etc. . The above patented technology belongs to the treatment equipment, which is used for patients with a certain degree of clinical and positive signs of the spine. All of them have a certain correction effect on the curvature of the spine, but the treatment effect is still unclear. People need devices that can maintain the normal physiological curvature of the spine and play a preventive role.

Utility model content

The utility model aims to provide a device for maintaining the normal physiological curvature of the spine, so as to solve the problem of preventing the physiological curvature of the spine from being in a suspended state for a long time when people sit and cushions, so that the four physiological curvatures of the spine are always in the sitting position when the human body is sitting. normal position.

The device for maintaining the normal physiological curvature of the spine provided by the designer is mainly composed of cervical vertebra pad, thoracic vertebra pad, lumbar vertebra pad, sacral vertebra pad, telescopic rod and support frame; the support frame is composed of two support rods and a fixed rod The upper ends of the two support rods are respectively fixed at the position of the lumbar cushion of the sleeve of the telescopic rod through the knob, and the lower ends are respectively fixed at both ends of the fixed rod to form a relatively stable shelf; In the casing, the upper and lower are connected to a horizontal plate respectively, and buttons are respectively installed on the horizontal plate to control the stretching or compression of the telescopic rod; The lower part is fixed on the telescopic rod; the thoracic and sacral vertebrae pads are respectively connected with the bottom of the cervical vertebra pad and the lumbar vertebra pad; wherein, the shape of the cervical vertebra pad and the lumbar vertebra pad is semi-cylindrical or ingot-shaped or pillow-shaped or trapezoidal, and the interior is The airbag is wrapped with a layer of sponge and flannel. The back of the cervical vertebra pad and the lumbar vertebra pad are fixed on the corresponding parts of the inner sleeves of the two telescopic rods, and the height is adjusted by sliding the upper and lower buttons on the telescopic rods respectively; There is a fixed knob at the junction of the lumbar vertebra pad and the outer sleeve of the telescopic rod, and the fixed knob can be stretched and folded;

The air nozzle on the air bag is connected with the trachea, a bead and a groove are arranged in the trachea, and a balloon is arranged at the end of the trachea, which is used to inflate the air bag.

The buttons installed on the above-mentioned horizontal plates are composed of buttons, springs, linkage rods, clips and inner tubes. The buttons are connected to the linkage rods through the springs, and the bottom ends of the linkage rods are fixed to the clips. Lift, drive the clip in the inner tube to move, pull the clip, and the inner tube is lifted; when the button is no longer pressed, the inner tube is inserted downward, so that the inner tube of the telescopic rod and the outer tube of the telescopic rod can move with each other to adjust the height.

The above-mentioned shaped part is a kind of rigid plastic such as engineering plastic ABS, rigid polyvinyl chloride plastic PVC, rigid polyethylene plastic PE, rigid polypropylene plastic PP; it can also be metal material such as aluminum material, aluminum alloy material , One of the stainless steel materials.

The use method of the utility model is as follows: when a person sits and uses the device placed on the seat, after the human body is seated, the fixing knob is adjusted to stretch the folded neck and waist telescopic rods, the fixing knob is tightened and the fixing rod is stretched, according to The upper and lower buttons for adjusting the height of the human body make the cervical and lumbar vertebrae pads on the telescopic rod in the required positions. Normally, the thoracic and sacral vertebrae are naturally located in the thoracic and sacral vertebrae of the human body at this time. When the 4 cushions are in the correct position, squeeze the small balloon repeatedly to inflate the airbag of the cervical or lumbar cushion, block the airway with the bead, and it can be used; when not in use, move the bead to the groove Deflate the air inside and loosen the fixed knob to make the telescopic rod folded for easy portability.

The device of the utility model for maintaining the normal physiological curvature of the spine can be made into a seat back cushion or a seat back. When sitting with your back on the seat or a suitable cushion, it can ensure that the body does not lean forward or slant, and maintain the normal physiological curvature of the spine. In addition, the height and thickness can be adjusted according to the height and thickness of the human body, so as to better maintain the normal physiological curvature of the spine. It is beneficial to spine health and is suitable for healthy people.
