The wiring of patients for obtaining medical measurements has many disadvantages. In order to limit these, a miniaturized module was developed which digitalizes analog signals and sends the signal wirelessly to the receiver using Bluetooth. Bluetooth is especially suitable for this application because distances of up to 10 m are possible with low power consumption and robust transmission with encryption. The module consists of a Bluetooth chip, which is initialized in such a way by a microcontroller that connections from other bluetooth receivers can be accepted. The signals are then transmitted to the distant end. The maximum bit rate of the 23 mm x 30 mm module is 73.5 kBit/s. At 4.7 kBit/s, the current consumption is 12 mA.
为获取医学测量数据而给患者布线存在诸多缺点。为了限制这些缺点，开发了一种小型化模块，该模块可将模拟信号数字化，并使用蓝牙将信号无线发送到接收器。蓝牙特别适合此应用，因为它能在低功耗的情况下实现高达10米的距离，且传输稳健并带有加密功能。该模块由一个蓝牙芯片组成，微控制器以这样一种方式对其进行初始化，即可以接受来自其他蓝牙接收器的连接。然后信号被传输到远端。这个23毫米×30毫米的模块的最大比特率为73.5千比特/秒。在4.7千比特/秒时，电流消耗为12毫安。
