Definitions

  • ABSTRACT This disclosure describes a portable, separable unit containing heart monitor and defibrillator portions. [521 U.S. Cl 128/2.06 R, 128/419 D, 20%67l/l64ld Both units have separate, rechargeable power [5]] lm CI A6) 5 /04 supplies.
  • This invention pertains to combination heart monitor-heart defibrillator units and more particularly one where the monitor and the defibrillator operate in one portable console or as separate portable units.
  • I a means for ascertaining the rhythm of the heart so that suitable diagnosis can be performed
  • the first is accomplished by providing an electrocardiagram either on a cathode-ray oscilloscope or on a strip of recording tape with the latter function provided by a defibrillator.
  • the monitor and the defibrillator functions were provided by separate instruments with separate power supplies, and not necessarily of the same manufacture. Subsequently manufacturers began to combine the monitor and the defibrillator functions into a unitary, portable but inseparable package with a single power supply.
  • the monitor is used much more frequently and for longer periods of time than the defibrillator.
  • the monitor is always used initially to enable diagnosis of the cardiac dysrhythmia but the condition diagnosed may not require use of the defibrillator.
  • the monitor will continue in use until the patient reaches a facility for permanent care, and during transport it is often desirable to have the monitor travel with the patient. If the monitor and the defibrillator are inseparable within a single package, the instrument although portable is often too cumbersome to place on or near the conveying stretcher or too awkward to use conveniently. Further, the defibrillator may be needed constantly at the emergency facility so that transport in a combined unit would be further undesirable.
  • FIG. 1 is a perspective view of the invention with the monitor portion removed and shown separately.
  • FIG. 2 is a perspective view of the invention with the monitor portion positioned in the main console.
  • FIG. 3 is a schematic diagram of a portion of the invention.
  • FIG. 4 is a perspective view of 'the'back monitor.
  • FIG. I shows the heart monitor-heart defibrillator combination 10, with the heart monitor portion 12 removed from the main console 14.
  • the heart monitor is preferably a battery powered, self-contained unit which nests in compartment 16 of the main console. Once removed from the compartment 16 the monitor, sinceit can be battery powered, can provide a portable means for monitoring a patients heart thus facilitating diagnosis in remote locations.
  • the defibrillator likewise is battery operated and is of a construction which makes it, alone or in combination with the heart monitor, a highly portable device. The details of the electrical circuits which comprise each of the monitor and defibrillator portions are not the subjects of this invention and will not be discussed herein.
  • the monitor unit 12 once removed from the housing operates on its own self-contained batteryunit.
  • the batteries employed typically, might be of the nickelend of the cadmium variety which are rechargeable and which can provide continuous operation for several hours.
  • the defibrillator is preferably battery operated employing similar type batteries and having suitable capacity for permitting numerous energy discharges of suitable watt-second capacity.
  • FIG. 3 shows in schematic, functional form the configuration required to allow the monitor unit to operate on its own power supply when removed from the monitor-defibrillator combination and then to operate on its own supply when it is replaced in its compartment 16 within the console 14.
  • the batteries 18 and 20 internal to the monitor unit each have one terminal thereof 22 and 24 respectively, connected to common or ground potential 26.
  • Their respecive high sides, 28 and 30, are connected to corresponding poles a and b of a double pole-double throw switch 32 which is shown schematically as separate units but which in fact is one switch.
  • switch 32 preferably a spring loaded, button type is positioned on the back panel 35 of the monitor unit.
  • the button, 31, protrudes outwardly therefrom so that when the unit 12 is positioned into the compartment 16, the button is depressed into the body of the monitor unit.
  • the switch in the depressed state is shown in FIG. 3, i.e., the wipers 33 a and b are connected to the open contacts 32 c and d.
  • the spring action of the switch extends the button and draws the wipers to the normally closed contacts 32 e and f.
  • each of the batteries are electrically connected to terminals 34 a and b on the female portion 34 of an interface connector.
  • the female portion 34, of the connector is mounted on the back panel 35 of the monitor unit 12.
  • the corresponding male portion 36 is mounted on the rear wall of the compartment 16 such that it engages the female portion when the monitor unit 12 is positioned into the compartment 16.
  • Contacts c and d of switch 32 do not have electrical leads connected thereto and are thus considered as the open positions. Contacts e and f are connected to female connector contacts 34 c and d respectively. Additionally the latter two contacts, since they carry the power supplied by batteries 18 and 20, are connected to the remaining electrical circuits within the monitor unit shown functionally by black box" 37.
  • a male connector 36 which is located so as to mate with the female connector 34 when the monitor unit is positioned in the console.
  • Contacts 36 a and b which mate with female contacts 34 a and b are connected to the poles a and b of a second switch 38 mounted on the front panel of the console 14.
  • This is a double pole triple throw switch, shown schematically as implementing two separate functions.
  • Switch 38 has an of position, and d; a Monitor Only" position, e and g and an ON" position,fand h.
  • Switch contacts e and f are electrically connected to each other and to male connector contact 360, while switch contacts g and h are connected to each other and to male connector contact 36d.
  • Switch 38 has two ON positions as far as the monitor unit is concerned.
  • the reason for the redundancy is that switch 38 can contain a third pole-contact set (not shown) which would be used to supply power to the defibrillator circuits. This third set would be wired such that only when the switch 38 is in the ON position would power be supplied to the defibrillator circuits.
  • the Monitor'Only position allows the monitor unit to be used alone while placed in the console.
  • a portable unit including heart monitor and heart defibrillator portions which comprises:
  • a removable heart-monitoring portion having a self-contained power supply, said monitoring portion capable of monitoring a patients heart, while positioned in said unit or removed therefrom;
  • first switch means for interrupting the flow of electric power between said power supply and electrical circuits within said monitor portion when said monitoring portion is positioned in said unit;
