【摘要】 尿失禁是公认的影响人类健康的五大疾病之一。目前,在我国女性尿失禁发病率占总人口的40%以上。但由于尿失禁牵扯到个人隐私,很多患者不愿去医院就医,而国内现有医疗资源很难为患者提供安全、隐蔽的治疗条件,国外公司生产的便携式尿失禁治疗产品,价格昂贵且都为有线式设计,构造方面的原因使得患者在治疗过程中存在暴露问题。因此,研制一种既方便安全,又能保护患者隐私的尿失禁治疗仪显得愈发紧迫。本课题基于尿失禁的发病机理,在分析总结国内外类似装置的基础上,自主研发了一种新型的无线便携式尿失禁治疗仪(以下简称:治疗仪)。该治疗仪包括电刺激探头和控制调节器。电刺激探头插入妇女骨盆内特定位置后,发出电脉冲对相应肌肉组织进行刺激,以达到应有的治疗效果,使之恢复正常机能。控制调节器用来控制电脉冲的幅度、频率和波形,使治疗最为有效。本设计的创新点有:首先,将无线射频技术结合单片机技术应用于肌电刺激,实现了控制器与探头之间的无线通信,避免了使用导联带来的种种不便。其次,对传统电刺激波形进行了优化,并将其应用于该治疗仪,提升了治疗仪的治疗效果。再次,高集成度的探头设计,使治疗仪成为真正意义上的便携式仪器。此外,采用了智能处理措施,设计出独特的探头电源管理和充电方案,简化了治疗仪的操作,并保证其长期可靠的工作。本文将从尿失禁及尿失禁治疗仪的背景及发展情况出发,介绍女性尿失禁的发病机理、分类及各种现有的治疗方法,分析、对比各种治疗方法及现有仪器的优劣后,并着重讨论治疗仪的设计思路方案,包括以下主要工作:系统的总体方案及各功能模块进行设计;探头与控制器之间无线通讯与控制系统的设计及开发;探头内+5V~+60V升压模块设计与开发;刺激波形的优化设计与实现;控制器内充电方案及友好人机界面的设计;探头刺激工作电路与充电电路之间切换电路的设计与实现。更多还原

【Abstract】 Urinary Incontinence (UI) is one of the five most acknowledged diseases that influence human health. Currently, the incidence of UI is more than 40% of the total female population in china. But this kind of therapy is related to some individual privacy, most of the patients are reluctant to be hospitalized in the hospital. However, the existing medical resource can not supply self-help therapeutic in a safe and private environment. And the portable UI therapeutic apparatus fabricated by oversea companies are too expensive, also they use cabled technique and there exist exposure problems to use these apparatus during the therapy. So there is a great necessity to develop new UI therapeutic equipment that can easily be applicable and solve the problems of the safety and privacy.This thesis discusses the pathogenesis of UI, analyzes and summarizes the similar equipment domestically and abroad. Then we developed a novel type of Wireless Electrical Stimulation Therapeutic Apparatus for UI (hereinafter called as WESTAUI) allodium. This WESTAUI is made up by two parts: a controller and an electrode probe. When insert the electrode probe into the specific position in the female pelvis, the controller will control the probe to emit electrical impulse via wireless radio frequency communication. The electrical impulse will activate the muscle and apply the akinetic muscle some type of treatments to help the muscle to recover its normal function. The controller also control the swing, the frequency and the shape of the pulse emitted from the electrode, to make the therapy much more efficient.Our design has following the innovations: firstly, the radio-frequency technique and single chip processor technique are brought up to the neuromuscular electrical stimulation. The WESTAU realized the communication between the controller and the electrical stimulation probe by adopting radio-frequency technique and also avoided kinds of discommodity from the cabled technique. Secondly, it reinforced the curative effect by using the optimized electric stimulative wave in the WESTAUI. Furthermore, we adopts a series of intelligent measures, e.g., the design of the unique scheme of power management, and the battery recharging in the electrode probe, and it simplified the operation of the apparatus and ensure it to work dependably in a long turn.The organization of this thesis is as follows: I start it with the evolution background of the UI, then I introduce the pathogenesis, the sorts and the existing therapy measures of the female UI. After contrast the quality of different apparatus and therapy measures, the emphasis is put on the discussion on the design scheme of the instrument: including the general system scenario, the design of each functional parts, the wireless communication and control system in the WESTAUI, the optimization of the +5V to +60V boost circuit in the electrode probe, optimization of the design of the stimulation current impulses, the design of the recharging scheme and the friendly interface between the controller and the probe, the design and realization of switching circuit between the stimulation circuit and the recharging circuit.更多还原
