An apparatus for obtaining electrical heart activity of an individual in a form capable of producing a twelve-lead electrocardiogram of an individual, said apparatus including: a right arm electrode; a left arm electrode; at least one leg electrode; a portable electrode support having a plurality of at least seven precordial electrodes fixed thereon. The at least seven precordial electrodes extend laterally across the support so as to assume different lateral positions across the human chest when the support is positioned over the chest. Circuitry is carried by the support in electrically connected relation to the electrodes and is capable of selectively operating a selected six of the plurality of precordial electrodes at positions which correspond to the six Wilson precordial leads for the individual. The circuitry is constructed and arranged to convert the electrical heart activity of the individual obtained by the electrodes into a form capable of producing a twelve-lead electrocardiogram.

Twelve-lead portable heart monitor

The present invention provides a peak flow meter which facilitates a subject's compliance with the use thereof. In one embodiment, the peak flow meter provides an alarm for indicating that the subject is due for a peak expiratory flow rate evaluation when the subject has failed to use the peak flow meter after a predetermined period of time. In another embodiment, the peak flow meter is provided with circuitry which derives a data result corresponding to the peak expiratory flow rate of air blown into the peak flow meter for a number of blows. A first comparator determines the best data result within the number of blows and a memory stores each best data result. A second comparator compares each best data result to a specified value and provides an enabling signal to an alarm when a best data result is a predetermined amount lower than the specified value. To provide an incentive for the subject to blow as hard as possible into the peak flow meter, the a comparator may also compare each data result to the previous data result and provide an indication when the most recent data result is greater than the preceding data result.

Specialized peak flow meter

A method and device for obtaining electrical heart activity of an individual in a form capable of producing a twelve-lead electrocardiogram of an individual. The device includes a portable electrode support having an array of six non-adhesive precordial electrodes fixed thereon at predetermined positions within the array which correspond with the Wilson precordial leads for the individual. The device also includes a right arm electrode, a left arm electrode, a left leg electrode and circuitry for converting the electrical heart activity of the individual obtained by said electrodes into a form capable of producing a twelve-lead electrocardiogram. The method includes the steps of applying the left leg, left arm and right arm electrode to the skin of the individual at locations such that the circuitry can be electrically operable to obtain leads I, II, III, AVR, AVL, and AVF therefrom. Human pressure is applied to engage the array of six precordial electrodes with the skin of the chest of the individual in an operative relation, and circuitry is operated for a time sufficient to obtain electrical heart activity of the individual in a form capable of producing an electrocardiogram.

Twelve-lead portable heart monitor and method

A device for measuring electrical activity of the heart of a user. The portable device includes structure for receiving at least two leads of electrical activity of the heart of the user. This information is amplified, and coupled to a memory to produce audio signals of a form suitable for transmission over telephone lines in response to input signals. These input signals can be either from the memory or from the output of the amplifier, depending on the mode being commanded. A control structure commands the mode of operation. Live mode allows the acquired input to pass directly to the speaker, to be passed over the telephone lines. Recording mode records the input. Time interval mode records the entire capacity of the memory once. Rolling mode continually acquires and displaces other information that was previously in place. The device plays back a plurality of channels from the memory simultaneously over the telephone line so that these plurality of channels are received by the other end in a synchronized fashion. In addition, the device can operate in either a silent mode, in which information is recorded without any audio information being produced, or a sound mode in which audio information indicative of the information that is being stored is produced.

Device for measuring multiple channels of heartbeat activity and

A heart monitoring device for use under emergency conditions including a portable housing, a pair of electrodes and a pair of electrical wires connecting the electrodes to the housing and to an electrical circuit carried therein. The electrodes are usable in two modes. One mode is a precordial mode wherein the electrodes are mounted on the exterior of the housing in spaced positions fixed with respect to the housing in commonly outwardly facing relation so as to be conveniently engageable with the skin of the chest of a user by manually engaging the housing and moving it with the electrodes fixed thereto into housing retained operative positions on the chest skin. The second mode is a non-precordial mode wherein the electrodes are removed from the housing and, preferably, self-retained within the armpits.

Ambulatory monitoring system with real time analysis and telephone

A device for use under emergency conditions in applying heart-lung resuscitation procedures and the like to a patient while supported thereon which enables such patient to be transported from an inaccessible location of attack onto an ambulance stretcher without removing such support, the device being in the form of a self-contained portable unit comprising a frame structure having parts relatively movable between a collapsed unit carrying position and an extended patient supporting treatment and a transporting position operable when disposed in the patient treatment and transporting position to be engaged on a horizontal surface such as a floor or the like for support in stable relation thereon and to engage and support a patient thereon in a supine position to provide for a relatively unyielding support of the patient's back area sufficient to effect cardiac compression through the application of periodic mechanical downward forces on the chest area of the patient. A heart-lung resuscitator assembly is carried by the frame structure for applying periodic mechanical downward forces on the chest area of the patient, the assembly being contoured adjacent the head end of the frame structure to support the head of the patient in a position extending downwardly from the adjacent back area so that the breathing channel is maintained in a favorable position for the reception of oxygen and including a face mask unit engageable with the face of a patient supported as aforesaid for supplying oxygen to the patient. A drug and equipment compartment assembly is provided on the frame structure for supporting containers of oxygen thereon for use with the resuscitator assembly.

Heart-lung resuscitator litter unit

A portable heart monitoring apparatus incorporating unique structural and functional features. Electrodes carried on the apparatus capture electrical signals representing the functioning of a heart beating therewithin and provides sensible output indications corresponding to predetermined characteristics of the electrical signals and, hence, of the detected heartbeat. One of the sensible outputs provided is the selective actuation of either of two logic lights indicating whether the heartbeat is above or below respectively a predetermined beating rate. The unit is automatically turned on by merely holding the instrument in the user's hand and the selective actuation of the various operational modes may be conveniently made by selectively placing one of the hands's digits (such as the thumb) from one touch contact point to another. Part of the operation in the test mode involves the effective testing of the reserve battery power without actually loading the battery. Structurally, the device is convenient to hold in the hand and includes, on one side, a ground plane for establishing electrical contact with the user's hand. The ground plane structure is also formed as an open-sided storage compartment for the electrodes and is surrounded by a wrap-around structure for self-storing of the electrode leads.
