An improved, low-cost stretchable band incorporating a conductor for disposition around the human torso or other three-dimensional object, and particularly intended for use with respiration monitoring apparatus, is disclosed. Also presented is an improved enclosure housing circuitry releasable connected to the conductor in the band when the band is incorporated in respiration monitoring apparatus.

Apparatus for making a stretchable band-type transducer particularly

The present invention is an apparatus and method for improving the detection of the inductance 'signal' generated by an inductive plethysmograph (12). Signal detection is improved by modifying the design of the inductive plethysmograph (12) and also by improving the design of the associated circuitry. By virtue of these improvements, the associated circuitry may be located remotely rather than on the transducer, as is the current practice. In one aspect of the invention, the impedance matching transformer (14) joining the inductive plethysmograph (12) to the oscillator (16) is selected such that the inductance of its primary winding is greater than about ten times the reflected inductance of the inductive plethysmograph (12) and the cable (24) joining it to the transformer (14). In accordance with another aspect of the invention, the inductive plethysmograph (12) is modified such that the conductor (20) incorporated therein encircles the relevant body portion a plurality of times. In yet a further aspect of the invention, the cable (24) connecting the inductive plethysmograph (12) to the transformer (14) is selected such that the ratio of the diameter of its screen to the diameter of its center conductor is minimized for reducing the inductance per unit length thereof.

An improved method for calibating a non-invasive apparatus for measuring respiration volume of the type wherein signals indicative of the rib cage and abdomen contributions to respiration volume are provided, and wherein at least one of the signals is multiplied by a predetermined weighting factor for reflecting the relative contributions of the rib cage and abdomen to respiration volume. The calibration method non-invasively determines the weighting factor by: totaling, during a period of breathing, a plurality of values of a parameter indicative of the relative amplitude, for each breath, of uncalibrated rib cage and abdomen signals; and dividing the average variability of the means of the total of the values of one of the rib cage and abdomen signals by the average variability of the mean of the tota of the values of the other signal. The quotient so derived represents the weighting factor. An apparatus for calibrating in accordance with the method is also disclosed.

Single position non-invasive calibration technique

A method and apparatus are shown for monitoring respiration volumes by continuously measuring, while the patient breathes, variations in the patient's chest cross sectional area, or preferably, variations in both chest and abdomen areas. Each area is measured by measuring the inductance of an extensible electrical conductor closely looped around the body, by connecting the loop as the inductance in a variable frequency LC oscillator followed by a frequency-to-voltage converter and a voltage display. Calibration is made by measuring the area variations for a few breaths while directly measuring corresponding volumes of breath, preferably while the patient assumes at least two body positions, for example sitting and supine. The method and apparatus may also be used to monitor changes in area of any non-magnetic object.

Method and apparatus for monitoring respiration

An improved, low-cost stretchable band incorporating a conductor for disposition about the human torso or other three dimensional object, and particularly intended for use with respiration monitoring apparatus, is disclosed. A method for making the band, which method is suitable to mass production techniques, is also disclosed. Also presented is an improved enclosure housing circuitry releasably connected to the conductor in the band when the band is incorporated in respiration monitoring apparatus.

Stretchable band-type transducer particularly suited for respiration

An apparatus and method for distinguishing between different types of apneic episodes. The method includes measuring a new index, TCD/VT, and measuring the phase relation between the abdominal and rib cage contributions to total respiration volume. The episode is classified as central, obstructive or mixed based on the value of TCD/VT and the phase relation.

Method and apparatus for distinguishing central obstructive and mixed

A method and an apparatus for administering a drug through a breathing passage for absorption on the mucous tissue of a patient includes introducing an aerosol of the drug into an expanded bag and bidirectional channel for communicating the drug with the breathing passage of the patient and otherwise is substantially impervious to the passage of air, collapsing the expanded bag while the bidirectional channel for communicating with the breathing passage is in position to deliver the drug into the breathing passage of the patient. A signal in a bidirectional channel indicates when the rate of passage of the drug exceeds a desirable limit, whereby the patient taking the drug is reminded to decrease the rate of collapse of the airbag, thereby maximizing drug utilization. The drug delivery device admits a drug-containing aerosol through a drug introduction opening while the collapsible airbag is at least partially expanded, the drug being introduced into the breathing passage with the contraction of the collapsible airbag.

Drug delivery method and inhalation device therefor

Improved method for calibrating non-invasive system for measuring respiration volume of the type including apparatus for providing signals indicative of rib cage and abdominal contributions to respiration volume, device for multiplying the rib cage and abdominal signals by predetermined weighting factors reflecting the relative contributions of the rib cage and abdomen to respiration volume, and device for summing the weighted signals for providing a signal proportional to respiration volume. Improved method determines the weighting factors by measuring respiration volume by alternate measuring apparatus, simultaneously recording the unweighted rib cage and abdomen signals and the signal from the alternate measuring apparatus for a first plurality of breaths based on a first relative contribution between rib cage and abdomen and for a second plurality of breaths based on a second relative contribution between rib cage and abdomen, dividing the rib cage and abdomen signals by the signal from the alternate measuring apparatus for each breath for defining first and second coordinates for each breath, and determining the x and y intercepts of a line approximation extending through the plurality of points defined by the coordinates, the reciprocals of the intercepts substantially equaling the weighting factors.

A device for measuring a predetermined respiratory volume comprises an elongate, air-tight flexible bag of the predetermined volume, the bag being closed at one end and open at the other; and an elongate substantially rigid tubular member extending into the bag through its open end and occupying a major portion of the length of the bag, the bag being secured at its open end to the tubular member for forming an air-tight seal between the bag and the tubular member, the portion of the tubular member extending into the bag having a plurality of distributed apertures along its length and the portion of the tubular member outside the bag having at least one opening defining a mouthpiece.
