Description

Postpartum waist recovery auxiliary system for obstetrical department

Technical Field

The invention belongs to the technical field of rehabilitation instruments, and particularly relates to a waist recovery auxiliary system for postpartum obstetrics.

Background

The lumbar vertebrae are the portion of the human spine located between the thoracic vertebrae and the sacrum, five of which are normal lumbar vertebrae, and four or six which are abnormal in development of a small number of people. Generally, the first lumbar vertebra and the second lumbar vertebra are from top to bottom, the medical X-ray lateral plate shows that the transverse processes 1-5 of the lumbar vertebra are arranged to be consistent with the lumbar lordosis, and the 3 rd lumbar vertebra is positioned at the top end of the lumbar lordosis of the spine. The lumbar vertebrae are generally in the same shape and generally divided into a front elliptic cylindrical vertebral body and a rear semicircular vertebral arch, the space enclosed by the two vertebral bodies is called vertebral foramen, the vertebral foramen of all lumbar vertebrae from top to bottom form the lumbar spinal canal of a human, and the cauda equina plexus emitted by the spinal cord is longitudinally arranged in the lumbar spinal canal from top to bottom, which plays an important role in controlling the sensation and the movement of lower limbs, maintaining normal defecation and regulating sweating. The anterior wall of the vertebral canal is the posterior surface of the vertebral body, the posterior margin of the intervertebral disc and the posterior longitudinal ligament, the two sides are intervertebral foramen surrounded by the vertebral pedicle of the vertebra and the upper and lower incisional tracks of the adjacent vertebral body, the posterior wall is the vertebral plate, the ligamentum flavum and the zygopophysis, and the fragile nerve is not damaged by the outside just because of the protection of the peripheral hard sclerotin.

Except for the time of lying and sleeping, the waist bears the force of more than 60 percent of the body weight of the human body in about two thirds of the time every day, and the bearing force of the waist is twice of the body weight when the human body stands; when the chair is supported by the backrest to sit, the lumbar vertebra is lightened due to partial weight born by the backrest; when the person sits without a backrest support, the bearing capacity of the waist is larger than that of the person standing, and in addition, the waist is stressed and aggravated by additional acting force during various working and sports, so that when the person lies flat in one day, the waist of the person is fully or overloaded, and various waist diseases are easily caused by fatigue. In view of the main structure and function of the waist, the diseases of the waist are mainly caused by the pathological changes of the lumbar, the intervertebral discs and the peripheral muscle groups, and the common diseases can be divided into two types: one is the pathological changes of lumbar vertebra structure, such as lumbar disc herniation, lumbar hyperplasia, lumbar spinal stenosis and the like; the other is the pathological changes of the lumbar muscle group, such as lumbar muscle strain, acute lumbar sprain and the like, and no matter what is the lumbar disease, the pathological changes destroy the external qualitative and internal stability of the waist and are manifested as the phenomenon of lumbago in different degrees.

Especially for puerpera after childbirth, the symptoms of lumbago of puerpera generally caused by endocrine change, physiological weight increase, easy-caused spinal biomechanical change, anesthesia and other complications include spinal and muscular diseases, lumbar hyperosteogeny, intervertebral disc protrusion, lumbar hypertrophy, spinal stenosis, lumbar fracture, spinal tumor, lumbar and chronic trauma and strain, lumbar muscle strain, ankylosing spondylitis and the like. Therefore, a postpartum recovery apparatus is needed to help the puerpera recover the health of the waist from the aspects of enhancing the stability of the lumbar vertebra and the muscle strength of the lumbar and abdominal muscles after childbirth.
