随着呼吸道疾病患者增加,尤其是自身免疫力差的儿童患者增多,比如孩子总是咳嗽,通过传统药物治疗或者打针注射,孩子吃药麻烦,打针怕痛,且经肌肉或者血液吸收药物比较慢,孩子受煎熬比较长;去医院看病排队挂号麻烦,等待时间较长,医院本身的环境也会存在交叉感染的风险;另外就是药物流经全身的话可能有副作用,不利于儿童的健康成长?/p>

病情反复,经常打针吊盐水,回到家中吃药见效慢,且是药三分毒,长期服用更可能有依赖性?目前有很多医院都已经开展雾化治疗的手段,相对传统服药或者注射治疗,无痛苦,见效快等优点。相对于传统的服药治疗哮喘等呼吸道的疾病的手段,医用雾化器是将药液雾化成微小颗粒,药物通过呼吸吸入的方式进入呼吸道和肺部沉积,从而达到无痛、迅速有效治疗,因此也受到了广大用户的青睐?/p>

𝟘𝟚. SGM66055系列在手持红外测温仪中的应用案例

在医用雾化器中,需要锂电池进行持续供电,但是锂电池的电压会随着电量的释放而发生下降,所以就需要一颗输出能力强,体积小的DCDC完成升压变换。国产半导体厂家圣邦微电子旗下的升压稳压器SGM66055在此类应用中匹配度很高。SGM66055可以转换为省电模式,通过降低开关频率保持高效率。它的防鸣电路可以抑制充电寄生电容,减少电磁干扰。经过SGM66055升压芯片升到5V给雾化器的主控MCU供电,它的输入电?.5-4.5V,固定输出电?V?nbsp;连续输出电流高达2.4A,峰值输出电流可?.2A,即使最小输出负载电流也可达0.9A?nbsp;开关频?.2Mhz,所需配置的电感感值小,节约布板面积。输出纹波小,调整迅速。轻载高效功能可以大大降低静态功耗,延长电池待机时间,完全符合医用雾化器的供电需求?/p>

?背景概述

电池化成是电池制造过程中的一个关键步骤,它对电池的性能、寿命和安全性具有重要影响。电池化成的基本原理是在电池内部建立起电化学反应,使正极和负极之间能够进行可逆的电荷转移。在化成过程中,电池会经历一系列的充电和放电循环,以激活电池材料并形成稳定的电极界面,并使电池达到设计容量。化成过程通常包括几个阶段,如预充电、恒流充电、恒压充电等。每个阶段的充电电流和电压都有一定的要求,以确保电池能够充分充电并达到最佳性能?/p>

电池化成基本结构如下图(模拟并联结构)。Buck/Boost转换器在充电时工作在降压模式,为电池提供充电电源,在放电时工作在降压模式;第一级运放,测量电池电压及电池单元或电池组的充电电流;第二级运放,用作电压回路或电流回路的调节;第三级运放(可选),缓冲运放输出馈送到升降压转换器中,以控制输出电压或电流;ADC,监测电池电压和电流;DAC,能够为恒流和恒压控制环提供精准的参考控制信号?/p>

随着个人便携设备和新能源汽车快速发展,锂电池市场需求持续增长,各个电池厂商对化成过程中锂电池充放电电流/电压测量的误差要求也显著提高,对整个测量控制电路中放大器、ADC/DAC、电压基准的误差要求也相应提高。同时,在激烈的市场竞争下,方案性价比高也是各个厂家要求之一。圣邦微电子能用更低成本实现更高精度、更高功率的电池化成I/V控制?/p>

随着全国乃至全球糖尿病患者越来越多,对血糖仪的需求也就越来越多,血糖仪是一种测量血糖水平的电子仪器,主要是用来检测糖尿病患者体内的血糖浓度的;平时使用血糖仪可以及时掌握血糖浓度水平,从而及时调整饮食和做运动,控制病情继续发展,因此它对于糖尿病患者来说是必不可少的。一般血糖检测分为传统指⾎检测(BGM)和连续⾎糖检测(CGM)两种?br>血糖高的人群大多采用传统的血糖仪通过采集指血配合试纸的测量方式来获取当前时间点的血糖数据,这个数据是相对科学准确的,缺点就是每天数次测量都需要扎针,对于一些晕血或者害怕扎针的人群来说,无疑是一种折磨?br>随着技术的进步,连续血糖仪被越来越多的糖友用户所认知,它一次性的扎入皮下组织,通过组织间液的葡萄糖浓度来生成实时的血糖数据,而且可以连续测试多达14天时间,每隔5分钟检测一次血糖,24小时不间断,尤其对于晕血晕针的糖友来说,再合适不过了,无论从经济角度还是简易操作方面都要胜过传统的血糖仪?/p>
