Description
Technical Field
The utility model relates to a medical monitoring equipment field specifically is a pressure measurement and control sensing device suitable for a brace is worn to horse hoof foot.
Background
Congenital equinovarus in the hoof of children is one of the most common lower limb musculoskeletal system deformities in orthopedics of children, and is mainly characterized by hind foot hoof, varus, high arch of middle foot and adduction of forefoot. According to the World Health Organization (WHO) data, about 13 million neonates worldwide suffer from talipes equinovarus every year, with an incidence rate of about 0.3-7.8 per thousand, which varies among people of different ethnic groups. In the past decades, the treatment mode of the talipes equinovarus gradually changes from the traditional operation treatment (posterior medial soft tissue release operation, posterior soft tissue release operation and the like) to the non-operation treatment mode mainly based on the Ponseti method, and a large number of researches report the good medium-and-long-term clinical follow-up curative effect. The Ponseti method mainly comprises two stages, wherein the first stage is a deformity correction stage, the high arch, adduction and varus deformity is corrected through special techniques and plaster, the residual horseshoe deformity needs to be corrected through percutaneous tenotomy, and the second stage is a brace maintenance stage, the corrected ankle part is maintained mainly through wearing a foot abduction brace with a connecting rod, and the deformity recurrence is prevented. Multiple studies show that independence of the child patient on the brace is closely related to the recurrence of the deformity, and the success rate of treatment can be directly influenced. The non-compliance of the sick children to the braces is 23% to 61% and the recurrence rate of the deformities is 14% to 41% reported in the past literature. Initial studies by professor Ponseti suggested that the brace was worn for 2 years, and the results showed that the rate of recurrence of deformities was 56%, while the brace was worn for a period of 4 years, with a significantly reduced rate of recurrence. According to the Ponseti method, the infant is worn all day for the first 3 months, and then 14 to 16 hours per day until the infant patient is 3 to 4 years old. Non-compliance with the brace is defined as less than 75% of the total recommended abduction brace effective wear time. Effective wearing of the brace requires that the heel is in line with the rear side of the shoe and the sole of the foot to maintain a good deformity correction position, and improper wearing reduces effective wearing time of the brace, thereby causing deformity recurrence and progression. In view of the influence of the compliance of the braces, a plurality of research reports try to improve the compliance of the children patients to the braces by improving the configuration of the braces, and further reduce the recurrence rate of deformity.
Although many years of research and improvement obviously improve the comfort, convenience and orthopedic power of the brace, improve the compliance of the brace to a certain extent and reduce the recurrence rate of deformity, the recurrence problem after the talipes equinovarus is corrected is still a difficult problem to the clinician. Whether the brace is worn correctly and the effective wearing time is achieved still depends on the execution and feedback of parents of the sick children in the current clinical practice, wherein a large number of subjective factors are not lacked. Recent JPO report of orthopedics authority journal of children records the wearing time of the infant patient by using a foot abduction brace provided with a pressure tester, and the result shows that the wearing time of the infant patient in the first 3 months is obviously shortened compared with the wearing time of the brace reported by the family, and the reduction rate difference of the wearing time of the infant patient in the first 2 months has significant statistical significance (p < 0.01). However, the reported research is not further continued and results such as quantitative indexes of wearing the brace, later-stage recurrence, final function evaluation and the like are obtained, and the monitoring equipment has the defects of simplicity, heaviness, no calibration, incapability of monitoring feedback in real time and the like. The great difference between the objective index and the subjective feedback of parents exists in clinical work, and no relevant mature equipment application exists in current clinical practice and research, so that the design of a portable, intelligent and standard pressure sensing measurement and control device capable of monitoring the feedback in real time becomes a task which is urgently needed in the current clinic, and the pressure sensing measurement and control device has a wide clinical reference prospect and an important scientific research value.
