Spine pressure measuring device using flexible sensor

Abstract

The invention relates to the technical field of medical instruments, and particularly relates to a spine pressure measuring device using a flexible sensor. The spine pressure measuring device comprises an orthopedic support; a flexible pressure sensor is movably adhered to the inner side wall of the orthopedic support; the flexible pressure sensor is connected with a controller through a wire; the controller comprises a shell; and a battery module, a memory card integration module, a microprocessor, a pressure sensor integration module, a time integration module and a Bluetooth integration module are regularly arranged in the shell. According to the design of the invention, the flexible pressure sensor which can be randomly detached and adhered or adjusted in position is matched in the support with the adjustable tightness degree, so that the wearing experience can be effectively improved; and by adopting the capacitive flexible pressure sensor and accurately setting a pressure change measuring and calculating method, the pressure acted on a human body by the orthopedic support can be accurately and instantly measured, meanwhile, the accuracy and effectiveness of pressure monitoring are improved, the use body feeling of a patient is improved, and the working pressure of medical personnel is relieved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a spine pressure measuring device using a flexible sensor. Background technique [0002] Spinal deformity is a three-dimensional deformity characterized by coronal plane deviation, sagittal plane imbalance, and cross-sectional rotation. Considering its progression over time, it can also be considered a four-dimensional deformity. Among them, juvenile idiopathic scoliosis is the most common, with a prevalence rate of 0.47% to 5.20%. Female patients are more common, and 90% of patients are aged 11 to 18. Adolescent idiopathic scoliosis progresses rapidly during puberty, and it has been reported in the literature that a difference of 5° in the Cobb angle represents a 95% possibility of a true difference, suggesting that the deformity has progressed. Changes in the patient's physical appearance will affect the patient's self-evaluation and psychological confidence. In se...

Problems solved by technology

[0003] The current scoliosis correction braces are designed by medical staff based on experience. The braces are mainly computer-aided design and 3D printing. There are few braces designed based on the mechanical analysis of the three-dimensional finite element model of the spine, and only in the compression mode. Simply adopt the method of pressurizing the pull ring, which needs to be given one by one. The amount of pressurization is not objective, and there is no pressure sensor installed, so it cannot be monitored. Human error will inevitably occur, and the brace will be too loose or too tight. Affect the correction effect, or even aggravate the condition

Specifically, if the brace is too tight, it will be over-extruded, resulting in skin ulceration and infection, which will seriously affect the quality of life of the patient; if the brace is too loose, it will not be able to play its corrective role. In the growth and development period, after wearing the brace, the brace is usually re-examined regularly for 8 months or 1 year. Once the brace is too tight during this period, it cannot be discovered in time, which is a waste of manpower and material resources. Unable to achieve the expected correction purpose and needs to be improved urgently

[0004] At present, the clinical brace pressure detection device is relatively rough in numerical display, and only provides an approximate pressure range on the instrument panel. The accuracy is not high, and it is even more difficult to use in scientific research. It has been reported in the past that the airbag pressure sensor was used. However, there are disadvantages such as air leakage, limited measurement sites, low sensitivity, and failure to improve the wearing experience of the brace.

However, there is currently no device to measure the pressure of the spinal column wearing an orthopedic brace by using a flexible pressure sensor
