Brace pressure detection and adjustment device and orthopedic brace

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to a brace pressure measuring and adjusting device.

Background

Spinal deformities are three-dimensional deformities characterized by coronal plane deviation, sagittal plane imbalance, and transverse rotation, and may also be considered a four-dimensional deformity in view of their progression over time. Wherein adolescent idiopathic scoliosis is the most common, the prevalence rate is 0.47-5.20%, female patients are common, and the onset age of 90% of patients is 11-18 years. Adolescent idiopathic scoliosis progresses rapidly in adolescence, and the probability that the difference actually exists is 95% when the difference value of the Cobb angle is 5 degrees reported in the literature, which indicates that the deformity progresses. The change of the physical appearance of the patient can influence the self-evaluation and psychological confidence of the patient, and the serious patient can also influence the balance of the cardiopulmonary function and the body, thereby reducing the life quality. With the deep knowledge of the pathophysiology and clinical treatment and the development and progress of spinal orthopedic technology and internal fixation instruments, the brace treatment is suitable for mild and moderate patients (such as the Cobb angle is 20-45 degrees), and the surgical treatment is suitable for progressive or severe malformation patients. The scoliosis correction brace is worn, so that the progress of the state of an illness can be effectively slowed and controlled.

The existing scoliosis correction brace is designed by medical workers according to experience, the brace mainly adopts computer aided design, 3D printing is adopted, braces based on mechanical analysis design of a spine three-dimensional finite element model rarely exist, and the brace is only simply subjected to pressurization pull ring in a pressurization mode, and the brace needs to be given one by one, so that the pressurization force is not objective, a pressure sensor is not installed, monitoring cannot be carried out, human errors inevitably occur, the condition that the brace is too loose or too tight is caused, the use experience is reduced, the correction effect is influenced, and even the illness state is aggravated. Specifically, if the brace is too tight, the brace is excessively squeezed, so that the skin is broken and infected, the life quality of a patient is seriously affected, if the brace is too loose, the brace cannot play a role in correction, and as teenagers are in the growth and development period, the brace is usually rechecked regularly for 8 months or 1 year after the braces are worn, once the brace is too tight in the period, the brace cannot be timely found, manpower and material resources are wasted, the expected correction purpose cannot be achieved, and improvement is urgently needed.

At present, the clinical brace pressure detection device is rough in numerical display, only provides a rough pressure range on an instrument panel, is low in accuracy and is more difficult to use for scientific research.
