Definitions
- the present invention relates generally to medical devices and, more particularly, to integrating voice controls and/or voice alerts into the medical device.
- pulse oximetry For example, one technique for monitoring certain physiological characteristics of a patient is commonly referred to as pulse oximetry, and the devices built based upon pulse oximetry techniques are commonly referred to as pulse oximeters.
- Pulse oximetry may be used to measure various blood flow characteristics, such as the blood-oxygen saturation of hemoglobin in arterial blood, the volume of individual blood pulsations supplying the tissue, and/or the rate of blood pulsations corresponding to each heartbeat of a patient.
- Pulse oximeters and other medical devices are typically mounted on stands that are positioned around a patient's bed or around an operating room table.
- a caregiver desires to command the medical device (e.g., program, configure, and so-forth) they manipulate controls or push buttons on the monitoring device itself.
- the medical device typically provides results or responses to commands on a liquid crystal display (“LCD”) screen mounted in an externally visible position within the monitoring device.
- LCD liquid crystal display
- this conventional configuration has several disadvantages.
- this conventional configuration relies upon physical contact with the monitoring device to input commands (e.g., pushing a button, turning a knob, and the like).
- Such physical contact raises several concerns. Among these concerns are that in making contact with the medical device, the caregiver may spread illness or disease from room to room. More specifically, a caregiver may accidentally deposit germs (e.g., bacteria, viruses, and so forth) on the medical device while manipulating the device's controls. These germs may then be spread to the patient when a subsequent caregiver touches the medical device and then touches the patient. Moreover, if the medical device is moved from one patient room to another, germs transferred to the medical device via touch may be carried from one patient room to another. Even in operating rooms where medical devices are typically static, germs may be transferred onto a medical device during one surgery and subsequently transferred off the medical device during a later performed surgery.
- germs e.g., bacteria, viruses, and so forth
- monitoring devices that rely on physical contact for command input may clutter the caregiver's workspace. For example, because the medical device must be within an arm's length of the caregiver, the medical device may crowd the caregiver—potentially even restricting free movement of the caregiver.
- caregivers may have difficulty manipulating controls with gloved hands. For example, it may be difficult to grasp a knob or press a small button due to the added encumbrance of a latex glove.
- conventional techniques for outputting medical data also have several potential drawbacks.
- conventional techniques for displaying outputs rely on LCD screens mounted on the medical device itself. Besides constantly consuming power, these LCD screens must be large enough to be visually accessed by a doctor or nurse. As such, the conventional LCD screens employed in typical medical devices also may be a barrier towards miniaturization of the medical device. Further, conventional screen-based output techniques may be impersonal to the patient and may lack configurability by the caregiver.

- the pulse oximeter 10 may include a main unit 12 that houses hardware and/or software configured to calculate various physiological parameters. As illustrated, the main unit 12 may include a display 14 for displaying the calculated physiological parameters, such as oxygen saturation or pulse rate, to a caregiver or patient. In alternate embodiments, as described in further detail below, the display 14 may be omitted from the main unit 12 .
- the pulse oximeter 10 may also include a sensor 16 that may be connected to a body part (e.g., finger, forehead, toe, or earlobe) of a patient or a user.
- the sensor 16 may be configured to emit signals or waves into the patient's or user's tissue and detect these signals or waves after dispersion and/or reflection by the tissue.
- the sensor 16 may be configured to emit light from two or more light emitting diodes (“LEDs”) into pulsatile tissue (e.g., finger, forehead, toe, or earlobe) and then detect the transmitted light with a light detector (e.g., a photodiode or photo-detector) after the light has passed through the pulsatile tissue.
- LEDs light emitting diodes
- the amount of transmitted light that passes through the tissue generally varies in accordance with a changing amount of blood constituent in the tissue and the related light absorption.
- the heart pumps an incremental amount of arterial blood into the pulsatile tissue, which then drains back through the venous system.
- the amount of light that passes through the blood-perfused tissue varies with the cardiac-induced cycling arterial blood volume. For example, when the cardiac cycle causes more light-absorbing blood to be present in the tissue, less light travels through the tissue to strike the sensor's photo-detector.
- These pulsatile signals allow the pulse oximeter 10 to measure signal continuation caused by the tissue's arterial blood, because light absorption from other tissues remains generally unchanged in the relevant time span.
- the senor 16 may take other suitable forms beside the form illustrated in FIG. 1 .
- the sensor 16 may be configured to be clipped onto a finger or earlobe or may be configured to be secured with tape or another static mounting technique.
- the sensor 16 may be connected to the main unit 12 via a cable 18 and a connector 20 .
- the pulse oximeter 10 may also include an integral microphone 22 .
- the integral microphone 22 may be configured to receive voice commands from a caregiver or user that can be processed into commands for the pulse oximeter 10 .
- FIG. 1 illustrates the integral microphone 22 as being located on a front facade of the main unit 12 , it will be appreciated that in alternate embodiments, the integral microphone 22 may be located at another suitable location on or within the main unit 12 .
- the pulse oximeter 10 may also include a speaker 23 .
- the speaker 23 may be configured to broadcast voice alerts or other suitable types of alerts to a caregiver or user.
- FIG. 1 illustrates the speaker 23 as being located on a side facade of the main unit 12 , it will be appreciated that in alternate embodiments, the speaker 23 may be located at another suitable location on or within the main unit 12 .
- FIG. 2 another embodiment of the exemplary pulse oximeter 10 featuring an external microphone and speaker in accordance with one embodiment is illustrated.
- the pulse oximeter 10 of FIG. 2 also includes the main unit 12 , the screen 14 , the sensor 16 , the cable 18 , and the connector 20 .
- the pulse oximeter 10 illustrated in FIG. 2 may also include an audio connector 24 suitable for coupling a headset 26 to the main unit 12 .
- the headset 26 may include one or more speakers 28 and an external microphone 30 .
- the one or more external speakers 28 may be employed by the pulse oximeter 10 to broadcast voice alerts or other suitable alerts to a caregiver or user.
- the external microphone 30 may be employed to receive voice commands for the pulse oximeter 10 , as described further below.
- FIG. 3 is a block diagram of an exemplary medical device 40 configured for voice control in accordance with one embodiment.
- the pulse oximeter 10 set forth in FIGS. 1 and/or 2 may comprise the medical device 40 .
- the medical device 40 may include a plurality of modules (blocks 41 - 52 ). These modules may be hardware, software, or some combination of hardware and software. Additionally, it will be appreciated that the modules shown in FIG. 3 are merely one exemplary embodiment and other embodiments can be envisaged wherein the module functions are split up differently or wherein some modules are not included or other modules are included.
- the medical device 40 may include a voice receiver 41 .
- the voice receiver 41 may include any suitable form of microphone or voice recording device, such as the integral microphone 22 (as illustrated in FIG. 1 ) or the external microphone 30 (as illustrated in FIG. 2 ).
- the voice receiver 41 may be configured to receive a voice (i.e., an acoustic wave) and to convert the voice into an electronic analog waveform.
- the voice receiver 41 may be configured to transmit the analog waveform to a voice sampling system 42 .
- the voice sampling system 42 may be configured to sample the analog waveform to create digital voice data.
- the voice sampling system 42 may be configured to sample the electronic analog waveform 16,000 times per second to create a digital waveform of pulse amplitudes. In alternate embodiments, other suitable sampling techniques may be employed.
- the voice processing system 44 may be configured to receive the digital waveform from the voice sampling system 42 and to convert the digital waveform into frequencies that can be recognized by a speech recognition system 46 .
- the voice processing system 44 may be configured to perform a fast fourier transform on the incoming digital waveform to generate a plurality of frequencies. The voice processing system 44 may then transmit the plurality of frequencies to the speech recognition system 46 .
- the speech recognition system 46 may be pre-populated or programmed with a plurality of frequency combinations that are associated with commands for the medical device 40 .
- frequencies combinations associated with the voice command “turn off alarm” may be associated with a command for the medical device 40 to silence an alarm.
- the particular frequency combinations may be pre-programmed or pre-configured.
- the frequency combinations may be programmed into the speech database via a voice training system 48 , which will be described in greater detail below.
- the speech recognition system 46 may also be coupled to a medical language model 50 .
- the medical language model 50 may be programmed with a plurality of command combinations that are prevalently used in controlling the medical device 40 .
- the medical language model 50 may store command combinations such as “turn oximeter off,” “turn alarm off,” “adjust volume,” “pause alarms,” and so-forth. In this way, the medical language model 50 may assist the speech recognition system 46 in determining the medical command associated with a particular voice command.
- the medical language model 50 may assist the speech recognition system 46 in determining the proper medical command when the speech recognition system 46 is able to recognize some portion but not all of a voice command. For example, if the speech recognition system 46 is able to recognize the first and third words of the medical command “turn off alarms,” but is unable to recognize the second word, the speech recognition system 46 may search the medical language model 50 for command combinations matching the recognized terms (i.e., “turn” and “alarms”). Because the medical language model 50 may be programmed with only those commands relevant to the operation of the medical device 40 , the medical language model 50 enables the successful recognition of medical commands that would otherwise be unrecognizable by conventional, generic voice recognition systems. The medical language model 50 may be preprogrammed, may be programmed through the voice training system 48 , or may be programmed via an external computer (not shown).
- the speech recognition system 44 may be configured to transmit the command to a pulse medical device system 52 .
- the medical device control system 52 may be configured to control the medical device. For example, if the medical device 40 were the pulse oximeter 10 , the control system 52 would be configured to control the main unit 12 as well as the sensor 16 to produce physiological monitoring results and/or alarms, which may be transmitted to the display 14 or the speaker 23 .
- FIG. 4 a flow chart illustrating an exemplary technique for processing a voice command in accordance with one embodiment is illustrated and generally designated by a reference numeral 60 .
- the technique 60 may be employed by the medical device 40 (as illustrated in FIG. 3 ) or the pulse oximeter 10 (as illustrated in FIGS. 1 and 2 ). It will be appreciated, however, that the technique 60 may also be employed by any other suitable type of medical device including, but not limited to, other forms of monitors, respirators, or scanners.
- the technique 60 may begin by receiving a voice (i.e., a portion of spoken audio).

- the pulse oximeter 10 may receive the voice via the microphone 23 or the microphone 30 .
- the technique 60 may include processing the received voice, as indicated in block 64 .
- processing the received voice may include converting the received voice into one or more frequencies that can be recognized by a speech recognition system, such as the speech recognition system 46 illustrated in FIG. 3 .
- the technique 60 may also include comparing the processed voice with a speech database and/or a medical language model, as indicated by blocks 66 and 68 , and as described above with regard to FIG. 3 .
- blocks 66 and 68 may include comparing the processed voice to a speech database within the speech recognition system 46 and/or the medical language model 50 .
- the technique 60 may involve identifying a medical device command associated with the processed voice based upon the one or more of the comparisons, as indicated by block 70 . For example, if comparisons to the speech database and/or the medical language model indicate that the processed voice is a command to “turn off alarms,” then technique 60 may involve identifying the medical device command as a command to turn off the medical device's alarms.
- the technique 60 may include prompting a user (e.g., the caregiver ) to confirm the new patient information was correctly determined, as indicated by block 72 .
- the pulse oximeter 10 may display the identified command on the display 14 and prompt the user to confirm the correctness of the identified command.

Description
- 1. Field Of The Invention
- The present invention relates generally to medical devices and, more particularly, to integrating voice controls and/or voice alerts into the medical device.
- 2. Description Of The Related Art
- This section is intended to introduce the reader to various aspects of art that may be related to various aspects of the present invention, which are described and/or claimed below. This discussion is believed to be helpful in providing the reader with background information to facilitate a better understanding of the various aspects of the present invention. Accordingly, it should be understood that these statements are to be read in this light, and not as admissions of prior art.
- In the field of medicine, doctors often desire to monitor certain physiological characteristics of their patients. Accordingly, a wide variety of devices have been developed for monitoring physiological characteristics. Such devices provide cargivers, such as doctors, nurses, and/or other healthcare personnel, with the information they need to provide the best possible healthcare for their patients. As a result, such monitoring devices have become an indispensable part of modern medicine.
- For example, one technique for monitoring certain physiological characteristics of a patient is commonly referred to as pulse oximetry, and the devices built based upon pulse oximetry techniques are commonly referred to as pulse oximeters. Pulse oximetry may be used to measure various blood flow characteristics, such as the blood-oxygen saturation of hemoglobin in arterial blood, the volume of individual blood pulsations supplying the tissue, and/or the rate of blood pulsations corresponding to each heartbeat of a patient.
- Pulse oximeters and other medical devices are typically mounted on stands that are positioned around a patient's bed or around an operating room table. When a caregiver desires to command the medical device (e.g., program, configure, and so-forth) they manipulate controls or push buttons on the monitoring device itself. The medical device typically provides results or responses to commands on a liquid crystal display (“LCD”) screen mounted in an externally visible position within the monitoring device.
- This conventional configuration, however, has several disadvantages. First, as described above, this conventional configuration relies upon physical contact with the monitoring device to input commands (e.g., pushing a button, turning a knob, and the like). Such physical contact, however, raises several concerns. Among these concerns are that in making contact with the medical device, the caregiver may spread illness or disease from room to room. More specifically, a caregiver may accidentally deposit germs (e.g., bacteria, viruses, and so forth) on the medical device while manipulating the device's controls. These germs may then be spread to the patient when a subsequent caregiver touches the medical device and then touches the patient. Moreover, if the medical device is moved from one patient room to another, germs transferred to the medical device via touch may be carried from one patient room to another. Even in operating rooms where medical devices are typically static, germs may be transferred onto a medical device during one surgery and subsequently transferred off the medical device during a later performed surgery.
- Second, beyond contamination, monitoring devices that rely on physical contact for command input may clutter the caregiver's workspace. For example, because the medical device must be within an arm's length of the caregiver, the medical device may crowd the caregiver—potentially even restricting free movement of the caregiver. In addition, caregivers may have difficulty manipulating controls with gloved hands. For example, it may be difficult to grasp a knob or press a small button due to the added encumbrance of a latex glove.
- Third, current trends in general medical device design focus on miniaturizing overall medical device size. However, as controls which rely on physical contact must be large enough for most, if not all, caregivers to manipulate with their hands, medical devices that employ these types of controls are limited in their possible miniaturization. For example, even if it were possible to produce a conventional oximeter that was the size of a postage stamp, it would be difficult to control this theoretical postage stamp-sized pulse oximeter with currently available techniques.
- In addition, conventional techniques for outputting medical data also have several potential drawbacks. For example, as described above, conventional techniques for displaying outputs rely on LCD screens mounted on the medical device itself. Besides constantly consuming power, these LCD screens must be large enough to be visually accessed by a doctor or nurse. As such, the conventional LCD screens employed in typical medical devices also may be a barrier towards miniaturization of the medical device. Further, conventional screen-based output techniques may be impersonal to the patient and may lack configurability by the caregiver.
- For at least the reasons set forth above, an improved system or method for interacting with a medical monitoring device would be desirable.

In an effort to provide a concise description of these embodiments, not all features of an actual implementation are described in the specification. It should be appreciated that in the development of any such actual implementation, as in any engineering or design project, numerous implementation-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one implementation to another. Moreover, it should be appreciated that such a development effort might be complex and time consuming, but would nevertheless be a routine undertaking of design, fabrication, and manufacture for those of ordinary skill having the benefit of this disclosure.
- Turning initially to
FIG. 1 , an exemplary pulse oximeter featuring an integral microphone in accordance with one embodiment is illustrated and generally designated by thereference numeral 10. Thepulse oximeter 10 may include amain unit 12 that houses hardware and/or software configured to calculate various physiological parameters. As illustrated, themain unit 12 may include adisplay 14 for displaying the calculated physiological parameters, such as oxygen saturation or pulse rate, to a caregiver or patient. In alternate embodiments, as described in further detail below, thedisplay 14 may be omitted from themain unit 12. - The
pulse oximeter 10 may also include asensor 16 that may be connected to a body part (e.g., finger, forehead, toe, or earlobe) of a patient or a user. Thesensor 16 may be configured to emit signals or waves into the patient's or user's tissue and detect these signals or waves after dispersion and/or reflection by the tissue. For example, thesensor 16 may be configured to emit light from two or more light emitting diodes (“LEDs”) into pulsatile tissue (e.g., finger, forehead, toe, or earlobe) and then detect the transmitted light with a light detector (e.g., a photodiode or photo-detector) after the light has passed through the pulsatile tissue. - As those of ordinary skill in the art will appreciate, the amount of transmitted light that passes through the tissue generally varies in accordance with a changing amount of blood constituent in the tissue and the related light absorption. On a beat-by-beat basis, the heart pumps an incremental amount of arterial blood into the pulsatile tissue, which then drains back through the venous system. The amount of light that passes through the blood-perfused tissue varies with the cardiac-induced cycling arterial blood volume. For example, when the cardiac cycle causes more light-absorbing blood to be present in the tissue, less light travels through the tissue to strike the sensor's photo-detector. These pulsatile signals allow the
pulse oximeter 10 to measure signal continuation caused by the tissue's arterial blood, because light absorption from other tissues remains generally unchanged in the relevant time span. - In alternate embodiments, the
sensor 16 may take other suitable forms beside the form illustrated inFIG. 1 . For example, thesensor 16 may be configured to be clipped onto a finger or earlobe or may be configured to be secured with tape or another static mounting technique. Thesensor 16 may be connected to themain unit 12 via acable 18 and aconnector 20. - The
pulse oximeter 10 may also include anintegral microphone 22. As will be described further below, theintegral microphone 22 may be configured to receive voice commands from a caregiver or user that can be processed into commands for thepulse oximeter 10. AlthoughFIG. 1 illustrates theintegral microphone 22 as being located on a front facade of themain unit 12, it will be appreciated that in alternate embodiments, theintegral microphone 22 may be located at another suitable location on or within themain unit 12. - The
pulse oximeter 10 may also include aspeaker 23. As will be described further below, thespeaker 23 may be configured to broadcast voice alerts or other suitable types of alerts to a caregiver or user. AlthoughFIG. 1 illustrates thespeaker 23 as being located on a side facade of themain unit 12, it will be appreciated that in alternate embodiments, thespeaker 23 may be located at another suitable location on or within themain unit 12. - Turning next to
FIG. 2 , another embodiment of theexemplary pulse oximeter 10 featuring an external microphone and speaker in accordance with one embodiment is illustrated. For simplicity, like reference numerals have been used to designate those features previously described in regard toFIG. 1 . As illustrated, thepulse oximeter 10 ofFIG. 2 also includes themain unit 12, thescreen 14, thesensor 16, thecable 18, and theconnector 20. However, in place of or in addition to theintegral microphone 22, thepulse oximeter 10 illustrated inFIG. 2 may also include anaudio connector 24 suitable for coupling aheadset 26 to themain unit 12. - As illustrated in
FIG. 2 , theheadset 26 may include one ormore speakers 28 and anexternal microphone 30. As will be described further below, the one or moreexternal speakers 28 may be employed by thepulse oximeter 10 to broadcast voice alerts or other suitable alerts to a caregiver or user. In addition, theexternal microphone 30 may be employed to receive voice commands for thepulse oximeter 10, as described further below. -
FIG. 3 is a block diagram of an exemplarymedical device 40 configured for voice control in accordance with one embodiment. For simplicity, like reference numerals have been used to designate those features previously described with regard toFIGS. 1 and 2 . In one embodiment, thepulse oximeter 10 set forth inFIGS. 1 and/or 2 may comprise themedical device 40. As illustrated inFIG. 3 , themedical device 40 may include a plurality of modules (blocks 41-52). These modules may be hardware, software, or some combination of hardware and software. Additionally, it will be appreciated that the modules shown inFIG. 3 are merely one exemplary embodiment and other embodiments can be envisaged wherein the module functions are split up differently or wherein some modules are not included or other modules are included. - As illustrated in
FIG. 3 , themedical device 40 may include avoice receiver 41. Thevoice receiver 41 may include any suitable form of microphone or voice recording device, such as the integral microphone 22 (as illustrated inFIG. 1 ) or the external microphone 30 (as illustrated inFIG. 2 ). As those of ordinary skill in the art will appreciate, thevoice receiver 41 may be configured to receive a voice (i.e., an acoustic wave) and to convert the voice into an electronic analog waveform. - The
voice receiver 41 may be configured to transmit the analog waveform to avoice sampling system 42. Thevoice sampling system 42 may be configured to sample the analog waveform to create digital voice data. For example, in one embodiment, thevoice sampling system 42 may be configured to sample the electronic analog waveform 16,000 times per second to create a digital waveform of pulse amplitudes. In alternate embodiments, other suitable sampling techniques may be employed. - The
voice processing system 44 may be configured to receive the digital waveform from thevoice sampling system 42 and to convert the digital waveform into frequencies that can be recognized by aspeech recognition system 46. In one embodiment, thevoice processing system 44 may be configured to perform a fast fourier transform on the incoming digital waveform to generate a plurality of frequencies. Thevoice processing system 44 may then transmit the plurality of frequencies to thespeech recognition system 46. - The
speech recognition system 46 may be pre-populated or programmed with a plurality of frequency combinations that are associated with commands for themedical device 40. For example, frequencies combinations associated with the voice command “turn off alarm” may be associated with a command for themedical device 40 to silence an alarm. As mentioned above, in one embodiment, the particular frequency combinations may be pre-programmed or pre-configured. However, in alternate embodiments, the frequency combinations may be programmed into the speech database via avoice training system 48, which will be described in greater detail below. - In addition, the
speech recognition system 46 may also be coupled to amedical language model 50. Themedical language model 50 may be programmed with a plurality of command combinations that are prevalently used in controlling themedical device 40. For example, if themedical device 40 were an oximeter, such as thepulse oximeter 10, themedical language model 50 may store command combinations such as “turn oximeter off,” “turn alarm off,” “adjust volume,” “pause alarms,” and so-forth. In this way, themedical language model 50 may assist thespeech recognition system 46 in determining the medical command associated with a particular voice command. - More specifically, in one embodiment, the
medical language model 50 may assist thespeech recognition system 46 in determining the proper medical command when thespeech recognition system 46 is able to recognize some portion but not all of a voice command. For example, if thespeech recognition system 46 is able to recognize the first and third words of the medical command “turn off alarms,” but is unable to recognize the second word, thespeech recognition system 46 may search themedical language model 50 for command combinations matching the recognized terms (i.e., “turn” and “alarms”). Because themedical language model 50 may be programmed with only those commands relevant to the operation of themedical device 40, themedical language model 50 enables the successful recognition of medical commands that would otherwise be unrecognizable by conventional, generic voice recognition systems. Themedical language model 50 may be preprogrammed, may be programmed through thevoice training system 48, or may be programmed via an external computer (not shown). - Upon recognizing a voice command as a command for the
medical device 40, thespeech recognition system 44 may be configured to transmit the command to a pulsemedical device system 52. As will be appreciated by those with ordinary skill in the art, the medicaldevice control system 52 may be configured to control the medical device. For example, if themedical device 40 were thepulse oximeter 10, thecontrol system 52 would be configured to control themain unit 12 as well as thesensor 16 to produce physiological monitoring results and/or alarms, which may be transmitted to thedisplay 14 or thespeaker 23. - Turning next to
FIG. 4 , a flow chart illustrating an exemplary technique for processing a voice command in accordance with one embodiment is illustrated and generally designated by areference numeral 60. In one embodiment, thetechnique 60 may be employed by the medical device 40 (as illustrated inFIG. 3 ) or the pulse oximeter 10 (as illustrated inFIGS. 1 and 2 ). It will be appreciated, however, that thetechnique 60 may also be employed by any other suitable type of medical device including, but not limited to, other forms of monitors, respirators, or scanners. - As illustrated by
block 62 ofFIG. 4 , thetechnique 60 may begin by receiving a voice (i.e., a portion of spoken audio). For example, in one embodiment, thepulse oximeter 10 may receive the voice via themicrophone 23 or themicrophone 30. After receiving the voice, thetechnique 60 may include processing the received voice, as indicated inblock 64. In one embodiment, processing the received voice may include converting the received voice into one or more frequencies that can be recognized by a speech recognition system, such as thespeech recognition system 46 illustrated inFIG. 3 . - The
technique 60 may also include comparing the processed voice with a speech database and/or a medical language model, as indicated byblocks FIG. 3 . For example, in one embodiment, blocks 66 and 68 may include comparing the processed voice to a speech database within thespeech recognition system 46 and/or themedical language model 50. - After performing one or more of these comparisons, the
technique 60 may involve identifying a medical device command associated with the processed voice based upon the one or more of the comparisons, as indicated byblock 70. For example, if comparisons to the speech database and/or the medical language model indicate that the processed voice is a command to “turn off alarms,” thentechnique 60 may involve identifying the medical device command as a command to turn off the medical device's alarms. - Next, after identifying the medical device command, the
technique 60 may include prompting a user (e.g., the caregiver ) to confirm the new patient information was correctly determined, as indicated byblock 72. For example, in one embodiment, thepulse oximeter 10 may display the identified command on thedisplay 14 and prompt the user to confirm the correctness of the identified command. If the user does not confirm the command (block 72), thetechnique 60 may cycle back to block 62 (see above) and re-prompt the user for the new patient information. If, however, the user confirms the command, the technique may execute the command, as indicated byblock 74. For example, in one embodiment, the user may confirm the command by speaking the word “yes” or the word “execute” in response to the displayed command. - As described above, the
pulse oximeter 10 and/or themedical device 40 may be employed in a variety of suitable medical procedures and/or environments. For example,FIG. 5A illustrates an exemplary operating room setting 80 employing thepulse oximeter 10 in accordance with one embodiment. As illustrated inFIG. 5A , theoperating room 80 may include afirst caregiver 82 a, asecond caregiver 82 b, and apatient 84. In addition, theoperating room 80 may also include an operating table 86 and thepulse oximeter 10. - As illustrated, the
caregiver 82 b may employ and/or interact with thepulse oximeter 10 by wearing theheadset 26. As highlighted inFIG. 5B , which illustrates an enlarged view of thecaregiver 82 b, thecaregiver 82 b may place thespeaker 28 over his or her ear and place theexternal microphone 30 over his or her mouth. In this way, thecaregiver 82 b may receive alerts and issue commands from and to themain unit 12 via theheadset 26. Advantageously, the functionality enables themain unit 12 to be placed at a remote location in theoperating room 80 such that themain unit 12 does not crowd the medical procedure taking place in theoperating room 80. However, those with ordinary skill in the art will appreciate that the embodiment set forth inFIGS. 5A and 5B is merely exemplary, and, as such, not intended to be exclusive. Accordingly, in alternate embodiments, thepulse oximeter 10 and/or themedical device 40 may be employed in any one of a number of suitable medical environments. - As described above, the
pulse oximeter 10 and/or themedical device 40 may be configured to receive voice commands. Additionally, however, thepulse oximeter 10 and/or themedical device 40 may also be configured to enable entry of patient information by voice. For example,FIG. 6 is a flow chart illustrating anexemplary technique 90 for setting up a patient record in a medical device in accordance with one embodiment. In one embodiment, thetechnique 90 may be executed by thepulse oximeter 10 and/or themedical device 40. - As indicated by
block 92 ofFIG. 6 , thetechnique 90 may begin by entering a new patent setup mode, as indicated byblock 92. Next, thetechnique 90 may involve prompting a user for new patient information, as indicated byblock 94. In one embodiment, prompting the user for new patient information may include displaying a message to the user on the display 14 (seeFIGS. 1-3 ). Alternatively, prompting the user may involve an audio or voice prompt, as described further below, or another suitable form of user notification. - Next, the
technique 90 may include receiving audio corresponding to the new patient information, as indicated byblock 96. In one embodiment, audio corresponding to the new patient information may be received over theinternal microphone 22 and/or theexternal microphone 30. For example, theexternal microphone 30 may receive patient information, such as patient name, age, and so-forth from thecaregiver 82 b wearing theheadset 26. After receiving the audio corresponding to the new patient information, thetechnique 90 may involve determining the new patient information from the received audio, as indicated byblock 98. In one embodiment, determining the new patient information may include processing the received audio and comparing the received audio to a speech database and/or medical language model, as described above with regard toFIGS. 3 and 4 . - After determining the new patient information from the received audio, the
technique 90 may include prompting a user (e.g., thecaregiver 82 b) to confirm the new patient information was correctly determined, as indicated byblock 100. For example, in one embodiment, thepulse oximeter 10 may display the determined patient information on thedisplay 14 and prompt the user to confirm the correctness of the determined patient information with a voice command (e.g., “correct,” “yes,” and so-forth). If the user does not confirm the new patient information (block 102), thetechnique 90 may cycle back to block 94 (see above) and re-prompt the user for the new patient information. - Alternatively, if the user does confirm the determined new patient information, the
technique 90 may include storing the new patient information, as indicated byblock 104. For example, in one embodiment, storing the new patient information may include storing the patient's name, age, and so-forth in a memory located within thepulse oximeter 10 and/or themedical device 40. - As described above, one or more embodiments described herein is directed towards a medical device configured to receive voice commands. Accordingly,
FIG. 7 illustrates atechnique 110 that may be employed to train a voice system in a medical device in accordance with one embodiment. In one embodiment, thetechnique 110 may be employed by thepulse oximeter 10 and/or themedical device 40. More specifically, in one embodiment, thetechnique 110 may be executed by thevoice training system 48 ofFIG. 3 . However, it will be appreciated, that in alternate embodiments, other suitable medical devices may employ thetechnique 110. - As illustrated by
block 112 ofFIG. 7 , thetechnique 110 may begin by entering a training mode. In one embodiment, themedical device 40 may be configured to enter a training mode in response to a depressed button or a sequence of depressed buttons on themedical device 40. Alternatively, in other embodiments, thepulse oximeter 10 and/or themedical device 40 may be configured to enter the training mode in response to a voice command and/or other suitable form of command or instruction. - After entering the training mode, the
technique 110 may include prompting a user with a medical device training routine, as indicated byblock 114. The medical device training routine may involve displaying one or more medical device specific words, phrases, or commands on thedisplay 14. For example, thepulse oximeter 10 may be configured to display commands such as “turn off alarms,” “turn down volume,” “show pleth,” or any other suitable voice command or instruction. - After prompting the user, as described above, the
technique 110 may include recording a response to the training routine, as indicated byblock 116. For example, thepulse oximeter 10 and/or themedical device 40 may be configured to record the response to the training routine via theexternal microphone 30. After recording the response to the training routine, thetechnique 110 may include storing the response in a speech database, such as the speech database within thespeech recognition system 46. After storing the response in the speech database, thetechnique 110 may cycle back to block 114 and repeat the training routine with additional words, phrases, or comments. In one embodiment,medical device 40 may be configured to cycle throughblocks voice training system 48. - Turning next to another embodiment,
FIG. 8 is a block diagram of amedical device 130 configured to broadcast voice alerts in accordance with one embodiment. As those of ordinary skill in the art will appreciate, conventional medical devices are configured to use buzzes and/or beeps to indicate medical alerts or alarms (hereafter referred to collectively as “alerts”). In addition to disturbing patients and medical practitioners (and possibly breaking a medical professional's concentration), these buzzes and beeps typically provide no other useful information to a listener other than indicating the presence of an alert condition. Advantageously, themedical device 130 illustrated inFIG. 8 is configured to produce custom voice alerts that can advantageously provide detailed information about the alert conditions while at the same time being less jarring and/or abrasive than traditional medical device alerts. - The
