Definitions

  • This invention relates to monitoring apparatus.
  • This invention has particular application to the monitoring of human physiological functions, and for illustrative purposes, reference will be made to such application.
  • the level of stress to which a human body is being subjected can be monitored by measuring physiological functions such as pulse rate, body temperature and body hydration. Measurement of these variables during exercise is highly desirable. For exercise to be most beneficial, the heart rate must be elevated above a value of sixty percent of the maximum recommended rate, while exercise which elevates the heart rate above the maximum recommended rate depending on age and fitness can lead to serious effects.
  • Measurement of body hydration is also very important to athletes, as it can provide an early warning of dehydration of the body. Temperature measurement, with or without other parameter measurements, may be used for the detection of hypothermia or hyperthermia in a wearer. An increase in heart rate may also warn of hypothermia or hyperthermia. Continuous monitoring of physiological parameters is also desirable for persons with a history of heart disease, or persons recovering from cardiac surgery.
  • this invention in one aspect resides in monitoring apparatus for monitoring a desired physiological function, said monitoring apparatus including:- sensing means for sensing the desired physiological function, said sensing means being detachably attachable to the body of a user; retaining means for retaining said sensing means adjacent a selected portion of the body of a user; signal processing means for processing the output from said sensing means; and indicating means for providing a sensible output which is variable in accordance with changes in the output from said sensing means.
  • the physiological function is pulse rate
  • the sensing means is in the form of a pulse rate sensor.
  • other physiological functions such as body temperature or body hydration level may be measured, and suitable sensing means such as thermometers, including laser thermometers, or skin resistivity measurement means respectively may be used.
  • the pulse rate sensor may take any desired form. For instance, dimensional changes in the body as a result of the dilation of an artery during the pulse cycle may be monitored by displacement sensing means, such as by a strain gauge, or pressure sensing means of any suitable form supported against the artery. It is preferred, however, that the pulse rate sensor be in the form of an ultrasonic transducer assembly disposed in such relationship to an artery or the like whereby changes in the rate of flow of blood or velocity during a pulse cycle may be sensed by doppler effect or by other sensible effects resulting from changes in the rate of blood flow, such as variations in arterial noise levels or size.
  • the ultrasonic transducer assembly may include piezoelectric or piezoceramic transducers, or any other desired ultrasonic transducers.
  • the indicating means may be formed in any desired configuration, and may include visual indication means, providing a visual display related to the output of the sensing means, and alarm means for indicating visually, audibly, or by tactile feedback, e.g. for underwater use, that the output from the sensing means has reached, or passed, a preset limit.
  • the visual indication means may be in any desired form such as an analog readout, but it is preferred that it be in the form of a digital display whereby existing digital watch technology may be utilised. Alternatively, a visual display unit (VDU) may be utilised for the indicating means.
  • VDU visual display unit
  • the alarm means may take any desired form, such as a flashing light. However, it is preferred that the alarm means be in the form of an audible alarm such as a buzzer, or a tactile alarm such as electrical signal generation means or the like producing signals applied to the skin, whereby a wearer may be made aware of an alarm condition while engaged in activity which does not permit the indicating means to be constantly observed.
  • an audible alarm such as a buzzer
  • a tactile alarm such as electrical signal generation means or the like producing signals applied to the skin
  • the retaining means may be in the form of a harness of adjustable length and may hold the sensing means adjacent any desired portion of a user's body.
  • the sensing means is held adjacent the wrist of a user and in close proximity to the radial artery therein, and the retaining means is in the form of a wristband which may also support the signal processing means and the indicating means.
  • the signal processing and the indicating means may be enclosed in a housing for their protection, and the housing may also enclose a timer or watch. If desired, the signal processing means, the indicating means and the timer may be integrated into an assembly such that it may be worn as a convenient alternative to a wrist watch.
  • the senor means may be held adjacent a portion of the animal, such as an artery, and the indicating means may be placed in a position convenient for viewing by a rider.
  • telemetering means may be provided such that the indicating means may be placed remote from the sensing means, such as beside a racetrack or an exercise facility.
  • the sensing means may be formed as a sensing assembly adjustably mountable relative to the housing along the wristband whereby the sensing assembly and the housing may be positionable in a desired spaced relationship around the wrists of users of differing size, such as with the housing adjacent the dorsal portion of the wrist and the sensing assembly adjacent the radial artery.
  • the wristband may include a flexible element such as an elastic section whereby the sensing assembly may be urged against the wrist of a user.
  • the sensing means may be of size and shape such that it may fit snugly between the radius bone and the tendons on the ventral aspect of a user's wrist, whereby movement of the sensing means relative to the radial artery in response to operation of the tendons may be minimised.
  • the sensing means may be spring biassed into contact with the wrist such that it may maintain firm contact with the skin of the ventral aspect of the wrist during movement of the wrist.
  • the retaining means may include transmission straps which include electrical connectors such as wires disposed therealong for coupling the sensing means and the indicating means.
  • the electrical connectors may be in the form of exposed conductor tracks which are contacted by pickups attached to the sensing means or the housing. It is preferred, however, that the electrical connectors be formed as reactive elements such as inductors or capacitors and that co-operating reactive elements be provided associated with the sensing means or the housing such that an electrical circuit may be completed between the sensing means and the housing without the use of exposed electrical conductors.
  • a transmission strap may be provided with a pair of flat-coiled inductors, and the co-operating reactive elements may be in the form of inductive coils such that transmission of data and power may be effected by inductive means.
  • Magnetic cores formed from materials such as ferrite may be associated with the flat-coiled inductors and/or the co ⁇ operating reactive elements for enhancing the transfer of data and power.
  • the signal processing means may include frequency-dependent filtering whereby the entry of extraneous noise which occurs at frequencies differing from the desired pulse rate signals into the pulse-counting circuitry may be minimised. If desired, more complex signal processing means may be utilised, including fourier analysis or auto ⁇ correlation such that false pulse registration due to extraneous noise occurring within the frequency band of the desired pulse rate may be minimised.
  • Noise-cancelling circuitry may also include an accelerometer, and the output from the accelerometer may be processed along with the signal from the sensing means whereby noise emanating from the sensing means as a result of mechanical shock may be substantially neutralised.
  • the signal processing means may include digital signal processing techniques such as pulse position prediction, limiting rate-of-change of pulse rate. Other techniques for separating valid pulse cycles from extraneous noise may include recognition means for recognising characteristic portions of a pulse cycle, such as the dicrotic notch, the shape of the pulse peak, the rate of rise or fall of the signal, or the width of the base of the pulse signal.
  • the signal processing means may be disposed for adaptive alteration of the signal processing technique according to the pulse rate and the relative magnitude of the pulse rate and noise signals.
  • multi-purpose monitoring apparatus including a plurality of sensing means associated with the monitoring of respective physiological functions whereby the indicating means may be utilised for the monitoring of said respective physiological functions.
