摘要:
The invention relates to a device for stimulating neurons, comprising a non-invasive stimulation unit for applying mechanically tactile and/or thermal stimuli to the body surface of a patient. The stimuli stimulate neurons with a pathologically synchronous and oscillatory neural activity. The device also comprises a measuring unit for recording measurement signals, which describe a neural activity of the stimulated neurons, and a control and analyzing unit for controlling the stimulation unit and analyzing the measurement signals. The control and analyzing unit is designed to actuate the stimulation unit such that the stimulation unit abrades at least one part of the body surface of the patient along a path and thereby periodically applies stimuli, to select at least two regions on the patient's body surface along the path where the phase synchronization between the periodic application of the stimuli and the neural activity of the stimulated neurons have a respective local maximum using the measurement signals recorded in reaction to the periodic application of the stimuli, and to actuate the stimulation unit such that the stimulation unit applies stimuli in a delayed manner in the at least two selected regions, said stimuli causing the phase of the neural activity of the stimulated neurons to be reset.

A vibration module for applying vibrational tractions to a wearer's skin is presented. Use of the vibration module in headphones is illustrated for providing tactile sensations of low frequency for music, for massage, and for electrical recording and stimulation of the wearer. Damped, planar, electromagnetically-actuated vibration modules of the moving magnet type are presented in theory and reduced to practice, and shown to provide a substantially uniform frequency response over the range 40-200 Hz with a minimum of unwanted audio.

摘要:
A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.

The sick bed (1) according to the invention has a frame (2) with rollers (3) and a bed (4). The bed (4) is arranged at a relatively steep angle with respect to the horizontal. The bed (4) can be rotated about an axis (9) in a direction indicated by an arrow (P), and consequently propped up. A patient strapped to the bed (4) will likewise be propped up. The verticalization of the patient affect the physiological parameters of the same. According to the invention, the angle of inclination of the bed (4) relative to the horizontal is set according to the measured physiological parameters of the patient fixed on the bed (4). The angle of inclination to be set is determined from measured values at certain intervals of time, in a regulation cycle utilizing the controller/regulator (8). In this way, the measured or other physiological parameters of a patient can be influenced in a targeted manner and changed to a specified target value and/or target curve.
