Abstract

本实用新型涉及的是一种婴幼儿体感测报器,本 体感测报器是主机、接收机、感温衫组成。主机内有 测温状态变换电路,体表测温放大电路、音响电路和 发射电路等,接收机内有接收电路。它能及时准确自 动报告婴幼儿体感冷热状态,其内部的特殊电路还能 防止儿童急性呼吸道感染疾病的发生。该测报器结 构简单,灵敏度高,使用安全方便,只要将NTC热敏 电阻附着于婴幼儿体表即可,是年轻父母、护理人员 的得力助手。

Description

本实用新型涉及的是一种电子婴幼儿体感测报器,属电子类产品。
目前,市场上有一种踢被报讯器,在婴幼儿踢被后发出报警信号,以提醒家长及时给婴幼儿盖上被子。但是该报警器也有局限性,就是报警精度不准确,它虽然能在儿童踢被后发出报警信号,以提醒人们给儿童及时盖被,但由于其适应范围极小,加之不能真正反映婴幼儿的体感冷热,因而仍给护理带来很多困难。
本实用新型的目的是要提供一种具有灵敏度高,准确反映婴幼儿体感冷热的报警装置。婴幼儿体感测报器由主机、接收机和体感衫组成。主机上设置有音乐报警片、指示器、电源开关及体感衫插座。体感衫设置在现有的内衣上设计成前、后、上、下各放一个感温器NTC热敏电阻,采用串联而成,体感衫与主机上的体感衫插座之间用一根插头线连接。
主机内有以下几部分电路组成:
1、测温状态变换电路 2、体感温放大电路 3、精密稳压电路、附加电路和发射电路。在测温状态变换电路中,设置有选择开关K1和状态变换开关K2。在精密稳压电路中由精密电压源和外接原器件构成。在体感温放大电路中和附加电路均由一块四运放集成块构成。在发射电路中由一块专用发射集成块及简单的外围电路构成。在接收电路中也有一块专用接收电路构成,此集成电路采用市售普通调频集成块免调试大大简化了调试手续。
下面结合附图作进一步说明:
图1:本机的电路方框图
图2:本机接收电路原理图
图3:体感衫的结构图
本实用新型的使用方法,将体感衫穿戴在婴幼儿的身上,并用一导线连接,接收机放在附近。当婴幼儿的身体体温较低时,体感衫上的温热敏电阻NTC阻值变小,使A1的正向电压升高,从而其输出电压随之变高。因此当A1输出电压高于双电压比较器两门限A2输出高电平,A3输出低电平,使LED1截止LED2导通。结果LED2发出绿光,表示婴幼儿体感冷。反之,当婴幼儿穿盖太多,使躯干皮温过高时,则会导致LED1发红光,同时音响电路工作、发射信号。接收机接到警报后,通知父母及时给婴幼儿增减衣服,以免过冷过热。

Claims (3)
