Definitions

  • This invention relates to medical monitoring apparatuses and, more specifically, to a wireless device for monitoring sleep apnea.
  • Sleep apnea is a condition in which the affected person stops breathing for periods of time during sleep. Sleep apnea is relatively frequent in the population and may become sufficiently severe to affect the person's health or even cause unexpected death. Conditions which produce sleep apnea include cardiopulmonary obstructive disorders, anatomic changes in the respiratory airways and these may be associated with aging or other medical problems, and neurologic or neuromuscular disorders, although neurologic causes are the least frequent underlying condition of sleep apnea.
  • Treatment of sleep apnea depends first upon accurate diagnosis as to the severity of the problem. Such diagnosis has, typically, required that the patient be monitored during sleep at a sleep disorders center. It will be easily appreciated that for the patient, having to sleep in unfamiliar surroundings while attached to various monitors, is to say the least an uncomfortable, logistically challenging and expensive affair.
  • the present invention advantageously provides a wireless monitoring patch or relatively thin plastic panel which may be adhered to a patient's skin, preferably over the chest, for collecting physiological data that may be used to diagnose sleep apnea.
  • the invention allows monitoring for sleep apnea in any setting chosen by the patient, for example, in the patient's home, rather than in a sleep laboratory. This monitoring flexibility enhances the likelihood of a correct diagnosis by allowing the patient to undergo monitoring in a comfortable setting of his/her own choice, rather than in the typical impersonal medical facility.
  • the present invention comprises an electrode array patch having a plurality of sensor inputs.
  • This patch may alternatively be referred to as a thin and relatively flexible plastic sheet or housing which holds or contains the components of the invention.
  • the patch is adhered to the skin of the patient to be monitored, preferably over the patient's chest. Adhering the patch may be by a coating or adhesive disposed on a surface of the patch during manufacturing or which may be applied when preparing the patient for monitoring.
  • biosensors such as cardiac electrodes require making intimate contact with the patient through an uninterrupted medium capable of allowing passage of the weak electrical signals being sensed.
  • the present invention is employed strictly in its sleep apnea sensing mode, without cardiac electrodes, it is not necessary that the patch be adhered to the patient and it may be secured to the patient by any effective alternative means sufficient for preventing the respiration and blood sensors from being dislodged during sleep.
  • Inclusion of cardiac electrodes in the patch will allow correlation of not only respiration data and blood oxygen saturation level, but also of cardiac rhythm data, so that a complete picture of sleep apnea may be analyzed.
  • the invention may also be of use as an adjunct in studies of the sleep/dream pattern of patients, in exercise physiology studies, and in other situations where the patient's respiration may require monitoring.
