小型调制解调器为家用监控仪器节省空间

制造商表示,TinyModem是全世界最小的拨号调制解调器。

随着病人监控应用越来越倾向于从医院转到家庭,医疗器械OEM正努力设计适合家用的小型产品。减少占地面积的一种方法就是采用更少的元器件,以降低设备的整体大小。Radicom Research公司(美国San Jose;www.radi.com)宣称已开发出一种全世界最小的拨号调制解调器,以帮助制造商实现目标。

TinyModem的大小仅为0.661.250.75英寸,内置RJ-11电话插孔,与体积更大的同类产品相比拥有全部标准功能。该调制解调器旨在嵌入基站中,用以收集来自互联监控装置例如心脏监护仪上的电极板或血氧装置中的信息。然后,这些信息通过调制解调器传至远程地点。该公司的OEM销售经理Floyd Kling先生表示:该元件最大的优势在于能为设计者提供灵活性。他们可以设计出体积更小的监控系统,也可以利用节省的空间为产品增加新的功能。

Kling先生称,由于大部分监控系统仍需使用连接导线,易于移动的基站可以为病人提供便利,他说:病人可能难以移动,希望能在一段时间内将系统放置在某处,然后转移到另外一处。这种调制解调器帮助设计人员设计出能在家中任何地方使用的产品。

该调制解调器的工作温度范围为40至85C,可耐受高达3750V的隔离电压。带有EMC、EMI屏蔽功能,内置数据泵,拨号数据传输速率为300至56Kbps。

尽管如今的消费市场普遍认为拨号连接相比宽带占尽劣势,这种速度较慢的技术在病人监控领域仍有一定优势。Kling先生解释说:目前使用家用监控系统的大多数病人并非成长在互联网时代,许多人对技术实在不怎么在行。拨号技术不要求他们对宽带有何了解,因为它们可以直接插到标准电话插孔中。

尽管如此,Radicom公司意识到将来的病人会更加乐于使用宽带和无线技术,因此公司计划在不久的将来推出基于这些技术的元件。Kling先生表示:蓝牙技术的兼容性极具重要价值。凭借蓝牙技术,病人无须移动基站监控装置可在家中的任何地方与其进行无线通信。
