Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
Referring to
Handle 40 provides a means for carrying the unit to a victim or patient. This allows the user to have a free hand for other equipment, handling a patient or other important tasks. Moreover, with multiple pieces of equipment housed in the same unit, the user needs to only look at the face of the unit to view the various displays for the different systems.
Thus, consolidating multiple medical devices into one unit provides easier handling and convenience for the user.
A convenient variation is illustrated in FIG. 2. Instead of having two covers, this embodiment has one cover 14 for covering the openings of compartments 20, 30. In this embodiment, only a single cover 14 is removed to access the various compartments of the housing 1.
This provides an advantage over the first embodiment since the user only needs to remove a single cover to access all the equipment. During an emergency, when time is of the essence, this provides an important advantage for the user of saving time. The rest of this variation is similar to the first embodiment and thus, the features are represented by the same reference numerals and a detailed description is omitted.
This variation provides an advantage over the first and second described in units in that the displays 80, speaker 50, and other various controls 60 are protected by the cover 16. Thus, during use the operator only needs to remove a single cover piece to access all components in the housing. After use, the single cover protects all the controls and displays, as well as the other equipment housed in the compartments from damage during storage or transport.
As noted above, each compartment 20, 30 holds one or more emergency medical devices. Several component variations are possible. For instance, the housing may combine a small-sized emergency oxygen unit (gas dispensing device) with an oximeter, a pulse display and electrode lead. As another alternative, either or both of the emergency oxygen unit and oximetry system may be combined with an Automatic External Defibrillator (AED), corresponding controls and paddle electrodes. In either case, the system may include a voice prompt system, selection controls and a speaker. Many other combinations are possible, as will be evident to those of skill in the art.
The oxygen dispensing device may be functional in two modes: manual mode, in which an on/off switch or lever simply controls on/off supply of oxygen, generally delivered at a fixed or variable low flow rate, or automatic mode, where the flow rate is variable and may be controlled either according to program control or via feedback from the oximetry unit. Included within the variable flow rate mode may be a ventilation mode for non-breathing victims, wherein liter flow and pressure are subjected to time sequencing according to a cycle corresponding closely to requirements the victim needs to return to a normal breathing pattern. Compartment 30 stores defibrillator shock paddle electrodes 121 and oximeter electrode 107. Several other component variations are also possible.
The defibrillation device and associated controls are contained entirely within the housing 1, and may be of a form known in the art, as represented by U.S. Pat. Nos. 5,797,969, 5,792,190, 5,749,902, 5,700,281, 5,716,380, 5,605,150, 5,549,659, 5,529,063, 5,243,975, 5,785,043, 5,782,878, 5,749,913 and 5,662,690, each of which is incorporated by reference herein. Several of these known defibrillators include voice prompting; the invention deviates from the known voice prompting scheme in that it also includes timely prompts for oximetry measurement and the administration of oxygen. The protocols for the coordination of oximetry, oxygen administration and defibrillation are known generally in the medical arts, and therefore will not be explained in detail here.
Housing 1 holds power source 90 (battery), and the known controls 110, 103 and displays 116, 118 for the defibrillator and oximeter. A speaker 50 is also housed in the housing 1, to be used in conjunction with voice prompting tools and controls 113.
An example of the use of the invention will now be described, in order to better explain the functionality of the invention.
At an accident scene, for example, it is determined that a victim is currently in cardiac arrest. Upon enabling the unit of the invention, controls 113 may be activated to enable the voice prompt system, which will guide the user through the steps necessary to operate the oxygen delivery, oximetry and defibrillation systems. Such voice prompt systems are known in the portable defibrillation arts, however, according to the invention the prior art system may be modified to include prompts for effecting oxygen administration and oximetry measurements.
For example, in this example of a non-breathing victim in cardiac arrest, the voice prompt system may guide the user through the following protocols:
initiate and deploy defibrillation system and paddles
administer electroshock treatment
initiate oxygen delivery in ventilator mode
deploy oximetry measuring electrode.
If the defibrillation is successful, as determined by a pulse reading, the voice prompt system may subsequently guide the user through switching of the ventilator mode to a regulated constant volume oxygen delivery mode which is more suitable for a breathing patient, and/or make other variations in oxygen delivery via program control or in response to oximetry readings. Naturally, many variations are possible as will be readily apparent to those of skill in the art.
In its most simple form, the integrated emergency medical systems of the invention may be substantially without interdependent control. For example, an emergency oxygen device can be combined with a defibrillation system, without any electromechanical connection therebetween. In such a case, if voice prompting is added, the system may prompt only for defibrillation, or both defibrillation and oxygen delivery, for example.
A more integrated and sophisticated system is illustrated in FIG. 4. In this system, a control processor controls operation of the various emergency medical units (oxygen delivery, defibrillation and oximetry), accepts feedback from each of these units, interfaces with and controls the voice prompt system, and drives the various displays 116, 118. When the operator selects AED or oximetry functions by operating inputs 103110, the processor controls defibrillator control 111 to generate an output waveform of a selected type in accordance with operator selection, and controls oximetry control section 102 in accordance with operator selection to perform various measurements and drives display 116 to display these measurements, e.g., pulse rate and blood O2 related measurements, to the operator in real time. Similarly, processor 101 drives LCD screen 118 to display user instructions and prompts, respiratory monitoring and diagnosis, and cardio diagnosis and monitoring data.
Processor 101 also interfaces with voice prompt system 112 to cause the latter to deliver a selected sequence of voice prompts via speaker 114 according to predetermined protocols, operator input and the condition of the patient as measured by the system, including sensors 107, in a manner generally similar to that known in the art.
As noted previously, the oxygen delivery system 105 can be controlled either manually or by automatic control. In a manual mode, for example, the system 105 may deliver oxygen at a fixed liter flow and pressure, or at a plurality of flow rates. In automatic mode, the system 105 may, in response to a control signal from processor 101 (or user input), deliver a time sequenced flow rate and pressure to operate as a ventilator. In response to user input, a control signal from processor 101 or feedback from oximetry control 102, the system 105 can be switched from ventilator mode to fixed flow rate mode, the latter being more suitable for patients capable of breathing on their own. Other fixed or variable flow rates may be elected via control signals from processor 101 or feedback from oximetry control 102.
With the present invention, a single therapy unit can combine emergency cardiac defibrillation and pulmonary oxygen administration in one convenient casing. An electrocardio diagnosis/monitoring/defibrillation device can be combined with electropulmonary blood oximetry/oxygen administration, including automated patient cardiopulmonary oxygen assessment and voice prompted therapy and resuscitation.
Although described herein as an interactive combination of oxygen delivery, oximetry and defibrillation systems, it will be apparent that the invention could be comprised of a combination of any two of these systems, with associated modification of the control mechanisms and voice prompts, as will be evident to those of skill in the art.
