A respiration monitor is disclosed which includes a simplified pneumatic breath detector, a pressure sensor connected with the detector, and an active low pass filter for filtering the output of the monitor to reduce signals not indicative of respiration, such as movement of and/or impacts upon the detector. The monitor may be linked with a transmitter for remote subject monitoring, and the entire monitor may be configured to be unobtrusively worn by the subject.

Apparatus and method are disclosed for monitoring selected physiological parameters of a subject, such as respiration and/or ECG information, and alerting a care giver at a remote location when an irregularity is recognized. The apparatus includes a sensor or sensors, a dual frequency, asynchronous transmitter unit for transmitting plural signals indicative of the sensed information, a local receiver/transmitter unit, and a remote receiver. The physiological parameters being monitored are sensed and processed to provide signals which are provided to a pair of transmitters. Transmission is selectively enabled at each transmitter, the first transmitting at a first frequency a signal indicative of real time monitored events and the second, under normal circumstances, transmitting, periodically, at a second frequency a signal indicative of monitored event count and updated subject status. When received at the local receiver, both signals are processed and retransmitted to the remote receiver where, if irregularity is indicated, the care giver is alerted.

Apparatus and method for remote monitoring of physiological parameters

A simplified transcutaneous nerve stimulating device is disclosed that combines simplicity of structure with dependability of operation. The device utilizes a 45 volt battery source for circuitry simplification by eliminating the need for circuitry such as voltage multipliers, with the battery source powering an oscillator and a pair of constant current regulated drive circuits from which pulses are alternately coupled to isolated output pairs connectable with electrodes positionable on the skin of a user for imparting stimulation pulses to the body of the user for pain suppression.

A temperature indicative hotpack is disclosed. A temperature monitoring unit has an indicating portion and a sensing portion with the monitoring unit being mounted on one liquid permeable wall enclosing a heat retaining material so that the temperature of the heat retaining material is accurately determined by the sensing portion within the enclosure and displayed externally of the enclosure by means of the indicating portion so that the hotpack can be safely and effectively utilized.

A miniaturized transcutaneous nerve stimulator is disclosed that utilizes a single 1.25 volt battery as the power source, yet provides a 30 volt DC power output over an extended period of time. The battery is connected to the primary winding of a step-up transformer with the primary also having a transistor connected in series therewith. The secondary winding of the transformer is connected with a full wave diode bridge circuit and a 30 volt Zener diode. Pulsing circuitry is also provided which includes a pulse rate and pulse width establishing multivibrators which are coupled through a buffer to a pair of Darlington amplifiers, which are also connected with the Zener diode and full wave diode bridge circuit. The output from the stimulator is coupled from the Darlington amplifiers, which amplifiers have a charging circuit connected therewith, to output terminals connectable with electrodes engagable with the skin surface of the subject.
