摘要:
It is an object of the invention to provide a user-friendly monitoring system with improved measurement quality, which is suitable for home use. This object is achieved according to the invention by a garment (1) comprising at least one dry electrode (2, 3, 4) for use with a monitoring system for monitoring physiological parameters of a recipient, the electrode (2, 3, 4) having a working surface which is to be brought into contact with the recipient's skin, characterized in that the working surface is automatically positioned at a point of close skin contact with a natural sweat layer present, if the garment (1) is worn by the recipient. The basic principle underlying the invention is that the position of the electrodes (2, 3, 4) on the body has an impact on the acquired signal quality. Therefore, it is an idea of the invention to arrange dry electrodes in positions of the garment (1) where close body contact is automatically obtained and a natural sweat layer is present, if the garment is worn. Because a natural sweat layer is already present around the armpit, the operability of the electrode (2, 3, 4) is given automatically, if it is located in the armpit area (10).
摘要:
A pulse detector that uses electromagnetic waves for detecting a patient pulse in conjunction with the administration of defibrillation and/or CPR. Electromagnetic waves are applied to a patient blood vessel and the reflected electromagnetic waves are analyzed for a Doppler shift, which is indicative of a pulse. In some applications the pulse detector can be used as a stand-alone device in conjunction with the administration of CPR. In other applications, the pulse detector is included with a defibrillator and provides pulsatile information that is analyzed in addition to ECG information in determining resuscitation therapy, or following defibrillation to ascertain its success.

A modulator for a communications system includes a spread spectrum coder and a pulse code modulator having a signal input port connectable to a signal output port of the spread spectrum coder. The modulator performs a robust and error free modulation and coding scheme by using a modified spread spectrum scheme combined with pulse code modulation. The communication system contains a low data rate, noise robust modulation and coding scheme using a very simple transmitter. This results in a very straightforward transmitter circuit, reducing size and costs of the transmitter.

The limited amplified biosignal (33) is then forwarded to the analogue-to-digital converter (34). The digitized signal is then analyzed by the analysis means (35), the results of the analysis, comprising the deduced health-related parameter is being displayed on a display (36) of the electric shaver. Additionally the health-related parameter and/or the raw data are transmitted to a remotely arranged unit by a built-in transmission means (38). Preferably, the transmission means (38) comprises a wire-less transmitter.
