Description

FIELD OF THE INVENTION

The present invention is generally related to a system and method for managing operating condition parameters in medical devices. The system would keep track of operating condition parameters (or air quality) within a medical device such as a surgical hood, wherein the operating condition parameters include, but are not limited to, carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), volatile organic compounds (VOCs), and/or air pressure. The system would provide feedback to the user regarding the operating condition parameters of the system while the system is being used so that the user is aware of the carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure conditions within the medical device especially if the user is wearing the medical device.

For example, if the medical device is a surgical hood having a ventilation system and the user is wearing the surgical hood, it would be desirable for the user to be made aware of the operating parameter conditions within the surgical hood (e.g., carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure) while the ventilation system is being operated. In this manner, if one of the operating parameter conditions within the hood exceeds a pre-determined threshold, the medical device could then interact with the ventilation system in order to attempt to correct the operating parameter condition that has exceeded its pre-determined threshold within the hood. Furthermore, the system could be equipped with an alarm (or alarms) such as an audible and haptic (vibrate) alarm that will alert the user that an operating parameter condition has exceeded a pre-determined threshold and/or that the system has attempted to correct the operating parameter condition that has exceeded its pre-determined threshold, but the system has not been successful in correcting the operating parameter condition that has exceeded its pre-determined threshold. In this latter instance, the user may need to remove the medical device and have maintenance performed on the medical device. Finally, the system would be able to collect information about the operating parameter conditions of the medical devices for user edification and/or product improvement.

BACKGROUND OF THE INVENTION

Prior to the present invention, as set forth in general terms above and more specifically below, it is known to employ various types of hoods and one-piece gowns or togas for use during medical procedures. The gowns are designed to cover the wearer completely and sterilely when they are attached to the hood. Currently, a helmet or other similar head support structure is donned by the wearer and the one-piece gown and the hood are conventionally attached to the helmet or other similar head support structure. Furthermore, it is known to provide a ventilation system that is also attached to the helmet or other similar head support structure or attached to the wearer.

When the hood and gown are donned by the wearer, it is important that the hood and gown completely and sterilely cover the wearer, as discussed above. In this manner, a closed area is created around the wearer's head and neck areas. Ventilation must be provided within this closed area so that the wearer can wear the hood and gown and still be able to properly perform the medical procedure without having to worry about encountering high levels of carbon dioxide (CO₂), temperature, humidity, oxygen (O₂) VOCs. and/or air pressure within the closed area.

Furthermore, it is known that medical devices need to be properly installed and maintained to function properly. A medical device that is not properly installed or maintained may fail at a very inopportune time, which could lead to a serious incident during a medical operation or procedure. For example, if the medical device is not properly installed or maintained, the wearer may experience high levels of carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure within the closed area.

It is a purpose of this invention to fulfill these and other needs in the medical device art in a manner more apparent to the skilled artisan once given the following disclosure.

The preferred system and method for managing operating condition parameters in medical devices, according to various embodiments of the present invention, offers the following advantages: ease of use; the ability to keep track of operating condition parameters in medical devices; the ability to automatically correct the operating condition parameter in the medical device without user intervention, if needed; the ability to provide feedback regarding the operating condition parameters in the medical device for wearer edification, preventative maintenance, and or product improvement: and the ability to provide audible and haptic (vibrate) alerts. In fact, in many of the preferred embodiments, these advantages are optimized to an extent that is considerably higher than heretofore achieved in prior, known systems and methods for managing operating condition parameters in medical devices.

DETAILED DESCRIPTION OF THE PREFERRED

Embodiments of the Invention

In order to address the shortcomings of the prior, known systems and methods for managing operating parameters in a medical device, it would be desirable to utilize a system and method for managing operating condition parameters in medical devices. The system would keep track of operating condition parameters (or air quality) within the surgical hood, wherein the operating condition parameters include, but are not limited to, carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), volatile organic compounds (VOCs), and/or air pressure. The system would provide feedback to the user regarding the operating condition parameters of the system while the system is being used so that the user is aware of the carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure conditions within the medical device especially if the user is wearing the medical device.

For example, if the medical device is a surgical hood having a ventilation system and the user is wearing the surgical hood, it would be desirable for the user to be made aware of the operating parameter conditions within the surgical hood (e.g., carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs. and/or air pressure) while the ventilation system is being operated. In this manner, if one of the operating parameter conditions within the hood exceeds a pre-determined threshold, the medical device could then interact with the ventilation system to attempt to correct the operating parameter condition that has exceeded its pre-determined threshold within the hood. Furthermore, the system could be equipped with an alarm (or alarms) such as an audible and haptic (vibrate) alarm that will alert the user that an operating parameter condition has exceeded a pre-determined threshold and/or that the system has attempted to correct the operating parameter condition that has exceeded its pre-determined threshold, but the system has not been successful in correcting the operating parameter condition that has exceeded its pre-determined threshold. In this latter instance, the user may need to remove the medical device and have maintenance performed on the medical device. Finally, the system would be able to collect information about the operating parameter conditions of the medical devices for user edification and/or product improvement.

A unique aspect of the present invention is that the pre-determined threshold can be determined according to, but not limited to, the following:

• • 1. A value set by the user for comfort;
  • 2. A value set by the hospital/system administrator policy;
  • 3. A value based upon best practices; and/or
  • 4. A value based upon compliance with Occupational Safety and Health Administration (OSHA) policies.

Referring now to FIG. 1-7, there is illustrated a helmetless support system 2 for use with surgical hoods and gowns. The helmetless support system 2 for use with surgical hoods and gowns can be used to support the one-piece surgical gown 4 and the surgical hood 14 without the need for the wearer 6 to wear a helmet. In this manner, one-piece surgical gown 4 and the surgical hood 14 completely and sterilely covers the head, neck, and torso of the wearer 6 when donned by the wearer 6. Also, the one-piece surgical gown 4 and the surgical hood 14 includes a clear faceplate 12. The helmetless support 2 further includes a helmetless surgical hood and gown support having a flexible headband 52 with attached lightweight front offsets 53 in front that can be releasably attached to the faceplate 12.

In particular, it is important that flexible band 52 be able to securely hold hood 14 off of the head of wearer 6 and allow the air to flow around the head of wearer 6, as will be discussed in greater detail later.

Helmetless Surgical Hood and Gown Ventilation System

Referring now to FIGS. 2-7, there is illustrated a ventilation system 100 for use with helmetless support system 2. The ventilation system 100 is constructed such that the fan speed can be controlled by the wearer 6 and/or the system 2 once the gown 4 and hood 14 have been donned. A face vent module 150 is used as a “yoke” to support the ventilation system 100 on the shoulders of the wearer 6 (FIG. 1). Finally, the wearer 6 can control the output from each of the various output apertures in face vent module 150 and neck vent module 350 in the ventilation system 100, as will be discussed in greater detail later.

As shown in FIGS. 2-7, helmetless support system 2 for use with surgical hoods and gowns having ventilation system 100 includes, in part, protective casing 120, face vent module 150, air filtration module 200, power module 250, yoke module 300, neck vent module 350, air flow generation module 450, printed circuit board (PCB) module 500, and the operating parameter measurement assembly 600.

Face vent adaptors 158, preferably, are constructed of any suitable, durable, high strength, medical grade material and are permanently connected to protective casing 120 near face vent air flow adjustors 160 and face vent air flow adjuster levers 162. Finally, face vent air flow adjustors 160 and face vent air flow adjuster lever 162, preferably, are constructed of any suitable, durable, high strength, medical grade material.

A unique aspect of the present invention is the use of removable face vents 152. In particular, removable face vents 152 are constructed in such a manner that allows the removable face vents 152 to be easily removed from the face vent adaptors 158 so that the removable face vents 152 can be cleaned, disinfected, and sanitized prior to the next usage of the helmetless support 2 for use with surgical hoods and gowns having ventilation system 100. Once the removable face vents 152 have been cleaned, disinfected, and sanitized, the removable face vents 152 can be easily slid onto the face vent adaptors 158 by locating the face vent connectors 156 on the face vent adaptors 158.

A further unique aspect of the present invention is the use of face vent air flow adjustors 160 and face vent air flow adjuster lever 162. In particular, the wearer 6 can adjust the amount of air flow that is being emitted out of the removable face vents 152 through the use of vent air flow adjustor 160 and face vent air flow adjuster lever 162. In this manner, the wearer 6 can conventionally manipulate face vent air flow adjuster lever 162 so that the amount of air flow is adjusted. For example, the wearer 6 may push/pull the face vent air flow adjuster lever 162 upwards which will cause the amount of air flow being emitted out of the removable face vents 152 to be reduced. Conversely, the wearer 6 may push/pull the face vent air flow adjuster lever 162 downwards which will cause the amount of air flow being emitted out of the removable face vents 152 to be increased.

Air Filtration Module 200

With respect to air filtration module 200, as shown in FIG. 4, air filtration module 200, includes, in part, air filter 202, air filtration adaptor 204, filter casing 206, and air filtration module wireless identification system 208.

Finally, it is to be understood that air filtration module wireless identification system 208 is a conventional wireless identification system such as an RFID tag that can be conventionally attached to or electrically connected to the air filter 202, as will be discussed in greater detail later.

A unique aspect of the present invention is the use of air filtration module 200. In particular, air filtration module 200 can be used to filter out air borne contaminants so that they do enter into the surgical hood 14 and surgical gown 4. As discussed above, only air filter 202 extends outside of the surgical hood 14 (FIG. 1). In this manner, only air going through the air filtration module 200 will be allowed to enter into the surgical hood 14 and surgical gown 4. Also, the air filter 202 can be easily removed and replaced. For example, wearer 6 can simply remove the air filter 202 and the filter casing 206 from the air filtration adaptor 204. The wearer 6 can then replace the used air filter 202 and filter casing 206 with a new air filter 202 and filter casing 206 by simply placing the new air filter 202 and filter casing 206 onto the air filtration adaptor 204. It is to be understood that the air filter 202 and filter casing 206 can be retained on the air filtration adaptor 204 by a snap fit, a threaded connection, a bayonet connection, a slidable connection or the like, as will be discussed in greater detail later.

It is to be understood that wireless power module identification system 258 is a conventional wireless identification system such as an RFID tag that can be conventionally attached to or electrically connected to the battery 252, as will be discussed in greater detail later. It is to be understood that instead of an RFID tag, the battery 252 may include a serial number that can be conventionally read/detected using a hardware data line that is configured to be used with the battery 252 through the wireless power module identification system 258. It is to be further understood that motor sensor/wireless identification system 262 includes a conventional printed circuit board 265, a tachometer 263, a RFID tag (not shown) that can be conventionally attached to or electronically connected to the fan motor 260, as will be discussed in greater detail later. Furthermore, printed circuit board 265 is configured with an algorithm that is used to determine the operating speed of the fan motor 260 based on one or more of the previously discussed pre-determined thresholds. Finally, in one embodiment, the algorithm could be updated with information uploaded onto the printed circuit board 265 through an interaction with processor 902 (FIG. 9) either manually or automatically based upon the desired interval in which such information is to be uploaded onto the printed circuit board 265.

A unique aspect of the present invention is the use of battery sensor 253. In particular, battery sensor 253 can be used to monitor the cycles and voltages of battery 250 so that it can be determined when the battery 250 needs to be replaced. Also, the battery sensor 253 can be used in conjunction with the processor 902 (FIG. 9) and printed circuit board (PCB) module 500 to utilize the information from battery sensor 253 in order to alert the user that the battery 250 is not functioning properly or to simply place an order for a replacement for battery 250.

Another unique aspect of the present invention is the use of battery doors 254. Battery doors 254 are conventionally connected to protective casing 120 so that battery doors 254 can swing (or pivot) open so that battery 252 can be easily installed into power module 250 or removed from power module 250. In particular, the wearer 6 can remove battery 252 from power module 250 by opening battery doors 254 and removing battery 252 from power module 250. The battery 252 can then be placed on a conventional battery charger (not shown).

In particular, yoke module 300 can be used to assist in retaining ventilation system 100 on the shoulders of the wearer 6. Furthermore, yoke 302 is removably attached to protective casing through the use of yoke connectors 304. In this manner, yoke 302 can be easily attached to and removed from protective casing 120. Furthermore, since yoke 302 is flexible, yoke 302 can be adjusted to fit the upper torso of the wearer 6 so that ventilation system 100 will remain securely retained on the shoulders and the upper torso of the wearer 6. For example, wearer 6 can position the ventilation system 100 with the yoke module 300 installed over his/her head and place the yoke module 300 on the upper torso of the wearer 6 (FIG. 1). The wearer 6 can then pull/push on yoke 302 while yoke 302 is connected to yoke connectors 304 so that yoke 302 firmly contacts the upper torso of the wearer 6 to assist in retaining the ventilation system 100 on the shoulders and upper torso of the wearer 6.

Another unique aspect of the present invention is the use of air flow generation module 450. In particular, as the fan motor 260 causes the impeller (or fan) 454 to rotate, the configuration of the impeller 454 causes air to be drawn through the air filter module 200. In this manner, the air filter module 200 can be used to filter the air being drawn into the ventilation system 100. Also, the back flow opening 456 is provided to allow air that is contained within the surgical hood 14 to also be drawn through back flow opening 456 in the direction of arrow D. In this manner, the back flow opening 456 provides for an even greater circulation of the air within the hood 14 while the ventilation system 100 is in operation.

Printed Circuit Board (PCB) Module 500

With respect to printed circuit board (PCB) module 500, as shown in FIG. 6, printed circuit board module 500, includes, in part, a conventional printed circuit board 502.

It is to be understood that operating condition parameter measurement assembly 600 can be adjusted so as to be able to position the operating parameter condition measurement assembly 600 within a desired distance away from the wearer's mouth. It is to be further understood that while the operating condition parameter sensor 602 is being used in conjunction with the helmetless surgical hood and gown support 50 and hood 14, operating condition parameter sensor 602 can be used on other medical devices located within the hood 14. Furthermore, operating condition parameter sensor 602 could be used in conjunction with filter 202 to measure the quality of the air that is being introduced into filter 202.

In another embodiment, operating condition parameter measurement assembly 600 can also include an operating condition parameter sensor 602a which can also be located adjacent to the fan motor 250 (FIG. 4) instead of being located adjacent to the user's mouth (FIG. 7). In still another embodiment, both operating condition parameter sensor 602 and 602a can be utilized within hood 14. It is to be understood no matter if either or both operating condition parameter sensor 602 and/or 602a are utilized within hood 14, the operating condition parameter sensor 602 and/or 602a should be located within the hood 14 so that the operating condition parameter sensor 602 and/or 602a can monitor the operating condition parameters or air quality (i.e., CO₂ levels, temperature, humidity levels, oxygen (O₂) levels, volatile organic compounds (VOCs), etc.) within the hood 14 while the hood 14 is being used during a medical procedure.

In another embodiment, the operating condition parameter measurement assembly 600 can also be equipped with a microphone assembly 604.

Operation of System for Managing Medical Device Maintenance and Medical Device Consumables

With respect to the operation of the system for managing medical device maintenance and medical device consumables, attention is directed to FIGS. 1-9. Assume that a medical device such as a surgical gown 4 (FIG. 1) is equipped with a conventional gown wireless identification system 30 having an RFID tag that can be conventionally attached to or electrically connected to the surgical gown 4, as discussed earlier. Secondly, assume that another medical device such as a fan filter 202 (FIG. 4) is equipped with a conventional wireless identification system 208 having an RFID tag that can be conventionally attached to or electronically connected to the air filter 202. Thirdly, assume that a still another medical device such as a battery 252 (FIGS. 4 and 5) is equipped with a conventional power module wireless identification system 258 having an RFID tag that can be conventionally attached to or electronically connected to the battery 252. Fourthly, assume that a fan motor 260 (FIG. 4) is equipped with a motor sensor/wireless identification system 262 having a tachometer 263 and RFID tag that can be conventionally attached to or electronically connected to the fan motor 260. It is to be understood that a processor 902 (FIG. 9) in conjunction with printed circuit board (PCB) module 500 can use the information from tachometer 263 or any other similar device in the motor sensor/wireless identification system 262 to determine the speed at which the motor 260 is operating and compare that speed to the speed at which the motor 260 should be preferably operating in order to determine if the filter 202 is clogged, the motor 206 is damaged, an operating condition parameter threshold has been exceeded, and/or the system 4 is otherwise malfunctioning to alert the user. Finally, assume that gown wireless identification system 30, air filtration module wireless identification system 208, power module wireless identification system 258, motor sensor/wireless identification system 262, and the operating condition parameter measurement assembly 600 are in electrical communication with printed circuit board 502.

In another embodiment, information from tachometer 263 or any other similar device in the motor sensor/wireless identification system 262 can be sent to processor 902 so that processor 902 in conjunction with printed circuit board (PCB) module 500 can control the speed of fan motor 260. In particular, operating condition parameter measurement assembly 600 (i.e., operating condition parameter sensor 602 and/or 602a) can be used to provide information to processor 902 regarding the operating conditions within the hood 14 (FIG. 7). For example, operating condition parameter sensor 602 and/or 602a can be used to detect carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure levels within hood 14. The operating conditions can be monitored while the wearer is donning the hood 14. The operating conditions data from operating conditions parameter sensor 602 and 602a can be transmitted through the printed circuit board (PCB) module 500 to the processor 902. In another embodiment, the processor 902 has been configured with operating condition parameter thresholds (such as CO₂ level should not exceed 1,200 ppm or 2,500 ppm depending upon the desired operating conditions). As discussed above, an algorithm running on the printed control board 265 determines the operating speed of the fan motor 260 based on one or more pre-determined thresholds, and the algorithm could be updated with data from the processor 902 (FIG. 9) and uploaded onto the printed control board 265 at a desired interval.

If at least one of the thresholds of an operating condition (carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs. and/or air pressure levels) is exceeded, the processor 902 in conjunction with printed circuit board (PCB) module 500 can then interact with the fan motor 260 to adjust the speed of the fan motor 260. In one embodiment, the tachometer 263 can then be utilized to monitor the adjustment in the speed of the fan motor 260 so that the desired adjustment in the speed of the fan motor 260 is achieved. For example, the processor 902 in conjunction with printed circuit board (PCB) module 500 can interact with the fan motor 260 to cause the fan motor 260 to quickly accelerate in speed in order to provide a large amount of fresh air inside of hood 14 if at least one of the thresholds of an operating condition (carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure levels) is exceeded, as discussed earlier. For example, if the CO₂ levels within hood 14 exceed 1,200 ppm (or 2,500 ppm depending upon the operating conditions), the introduction of large amount of fresh air into the hood 14 over a desired period of time may correct the operating condition in which the threshold of this operation condition has been exceeded. The operating parameter sensor 602 and/or 602a will continuously monitor the operating conditions within hood 14 while the wearer is donning the hood 14 to determine that no other operating conditions within hood 14 are exceeding their operating thresholds.

In still another embodiment, the processor 902 in conjunction with printed circuit board (PCB) module 500 can interact with the fan motor 260 to cause the fan motor 260 to gradually accelerate or decelerate in speed in order to provide a desired amount of fresh air inside of hood 14 if at least one of the thresholds of an operating condition (carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure levels) is exceeded. For example, if the CO₂ level within hood 14 exceeds 2,500 ppm, the fan motor 260 can be activated to begin to introduce an amount of fresh air into the hood 14 in order to correct the operating condition in which the threshold of this operation condition has been exceeded. In this example, once it has been determined that the CO₂ levels are below 2,500 ppm, the fan motor 260 can be decelerated or turned off to cause the fan motor 260 to slow or stop the delivery of fresh air into the hood 14. As discussed above, the operating parameter sensor 602 and/or 602a will continuously monitor the operating conditions within hood 14 while the wearer is donning the hood 14 to determine that no other operating conditions within hood 14 are exceeding their operating thresholds.

In another embodiment, the tachometer 263 can then be utilized to monitor a “full” condition. For example, tachometer 263 can be used to detect if filter 202 is clogged, motor 260 is failing, or the like. In any of these instances, the processor 902 in conjunction with printed circuit board (PCB) module 500 can then be configured to send an alert to the user informing the user that a “full” condition exists and needs to be looked at.

In another embodiment, the operating condition information forwarded from the operating parameter sensor 602 and/or 602a to the processor 902 can also be stored in data storage 906 or forwarded to a remote computer 965 associated with the wearer or a system administrator so that the wearer and/or system administrator will have access to the operating conditions within the hood 14 while the wearer is donning the hood 14. For example, the remote computer 965 may be equipped with a graphical user interface (not shown) that will allow the wearer and/or the system administrator to view the operating conditions within the hood 14 in a graphical format or some other similar format that will allow the wearer and/or system administrator to quickly and easily ascertain if there are any operating conditions within the hood 14 that are being exceeded while the wearer is donning the hood. Furthermore, the information regarding the operating conditions can be used for subsequent wearer edification, preventative maintenance, and or product improvement.

In one embodiment, the wearer and/or system administrator can be provided with an operating parameters (or air quality) health score. In this manner, after the medical procedure has been completed, the wearer and/or system administrator can be provided with a color score such as a green/yellow/red score. In this embodiment, the color would provide the wearer and/or system administrator with information about the air quality within hood 14 while the wearer was performing the medical procedure. For example, the color green could be associated with a good health score (the thresholds of an operating condition were not exceeded within the hood 14 during the medical procedure). The color yellow could be associated with a fair health score (only 1 or 2 of the thresholds of an operating condition were exceeded within the hood 14 during the medical procedure). The color red could be associated with a poor health score (many of the thresholds of an operating condition were exceeded within the hood 14 during the medical procedure).

Furthermore, operating conditions could be monitored every 30 seconds (or other desired time period). In this manner, if the wearer was performing a medical procedure that required more than usual manual exertion, it is possible that the wearer's CO₂ output, humidity, oxygen (O₂), VOCs, and/or temperature within the hood 14 might be greater than during a less strenuous medical procedure. The information related to the amount of CO₂ that the wearer is exerting, along with the increased humidity, temperature, oxygen (O₂), and VOC levels, could be useful to the wearer and/or the system administrator so that possibly the speed of the fan motor 260 could be automatically increased in similar medical procedures in the future thereby maintaining the CO₂, humidity, oxygen (O₂), VOC, and/or temperature levels within the hood 14 below the threshold levels.

Another unique aspect of the present invention is that the information obtained for use in determining the operating parameter health score can also be used to create best practices for air quality, threshold, and usage settings. In particular, data that is related to the operating parameters (or air quality) health score data and is temporarily stored in memory 904 under data 916 can be executed by processor 902 from a server (FIG. 9) to determine best practices such as fan speed, optimum CO₂ levels, humidity levels, temperature levels, oxygen (O₂) levels, and/or VOC levels. This data can then be used in conjunction with machine learning techniques and artificial intelligence (AI) algorithms to recommend best practices for consumable operation and management in order to improve air quality within the hood 14 and when using the ventilation system 100.

In still another embodiment, processor 902 can also be configured to send a signal to an alarm (not shown) such as an audible and haptic (vibrate) alarm to provide an alert to the user to inform the user that at least one of the thresholds of an operating condition (carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure levels) has been exceeded. In this instance, if the processor 902 interacts with fan motor 260 upon determining that an operating condition threshold has been exceeded, but the fan motor speed is not adjusted to attempt to correct the operating condition being exceeded, the alarm can provide a backup to the wearer and/or the system administrator that the system 2 needs to be looked at to determine why the system 2 allowed the operating condition to exceed its operating threshold.

With reference to FIG. 8, a computer-implemented method 800 is illustrated that describes one embodiment for managing operating condition parameters in medical devices. The method 800 is performed by at least a processor of a computer system that accesses and interacts with memories and/or data storage devices. For example, the processor at least accesses and reads/writes data to the memory and processes network communications to perform the actions of FIG. 8.

Attention is now directed to FIG. 8. With reference to FIG. 8, a computer-implemented method 800 is illustrated that describes one embodiment for managing operating condition parameters in medical devices. The method 800 is performed by at least a processor of a computer system that accesses and interacts with memories and/or data storage devices. For example, the processor at least accesses and reads/writes data to the memory and processes network communications to perform the actions of FIG. 8.

With reference to FIG. 8, at 801, the method 800 is initiated when the end user (usually the wearer of the hood 14 and gown 4) interacts with a remote computer 965 such as a mobile communication device that is configured with a mobile app (iOS and Android) that is “paired with” or otherwise interacts with the medical device (e.g., the hood 14 and/or the ventilation system 100 prior to the medical procedure). In one embodiment, the medical device can be selected by the end user either by selecting from a list of medical devices or scanning the barcode on the medical device before the surgery.

In another embodiment, the end user can either download the end user's fan speed preferences through the remote computer 965 to the processor 902 where the preferences are stored in the data storage 906. In another embodiment, the user can also download and store threshold values for the operating conditions such as, but not limited to, carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOC, and/or air pressure levels.

With reference to FIG. 8, at 802, the method 702 is initiated when operating condition parameter sensor 602 and/or 602a monitor the operating conditions within hood 14 (FIG. 7) while the wearer is donning the hood 14. As discussed above, the operating condition parameter sensor 602 and/or 602a can be used to monitor operating parameter conditions such as, but not limited to, carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure levels.

In block 804, in one embodiment, if at least one operating condition parameter has exceeded an operating parameter threshold (e.g., the CO₂ level within the hood 14 has exceeded 1,200 ppm or 2,500 ppm depending upon the operating conditions), the operating condition parameter sensor 602 and/or 602a will determine this high level of CO₂ within hood 14 and forward this information to processor 902.

In block 806, upon determining that at least one operating condition parameter has exceeded its operating condition threshold, the processor 902 in conjunction with printed circuit board (PCB) module 500 can then interact with fan motor 260 in order to adjust the speed of the fan motor 260.

In one embodiment, the fan motor 260 can be adjusted to operate the impeller 454 at a “constant” setting. For example, the wearer may set an initial fan speed at 2 out of 10. If the CO₂ operating parameter condition within hood 14 is detected above 1,200 ppm (or 2.500 ppm depending upon the operating conditions), the processor 902 can also be configured to send a signal to an alarm (not shown) such as an audible alarm (such as a beep) to the wearer and/or a haptic (vibrate) alarm (such as a vibration from the fan motor 260) to provide an alert to the user to inform the user that at least one of the thresholds of an operating condition (carbon dioxide (CO₂), temperature, humidity, oxygen (O₂), VOCs, and/or air pressure levels) has been exceeded. As discussed above, the fan motor 260 can be adjusted to operate the impeller 454 at a desired speed and/or a desired time in order to attempt to correct the operating condition so that the operating parameter condition does not exceed its operating parameter threshold. The processor 902 in conjunction with printed circuit board (PCB) module 500 will then instruct the fan motor 260 to slowly increase the fan speed to 3, 4, or 5 (which is measured by the tachometer 263) until the CO₂ level as measured by the operating condition parameter sensor 602 and/or 602a goes below the operating condition parameter threshold. Finally, the fan speed will stay at this higher level unless manually turned down by the wearer.

In another embodiment, assume that the wearer has set the operating condition parameter for CO₂ to be at 1,200 ppm and the correction or mitigation method is set to “purge”. The wearer also sets the fan speed to 2 out of 10. If the CO₂ operating condition within hood 14 is detected above 1,200 ppm, the ventilation system 100 may be equipped to provide an alarm (such as a beep) to the wearer and the fan motor 260 may provide an alarm (such as a vibration), as discussed above. The processor 1502 in conjunction with printed circuit board (PCB) module 500 will then instruct the fan motor 260 to quickly increase the fan speed to 9 or 10 (which is measured by the tachometer 263) for a short period until the CO₂ level as measured by the operating condition parameter sensor 602 and/or 602a goes below the operating condition parameter threshold. Finally, the fan speed will return to the initially selected level.

In block 808, the operating condition parameter sensor 602 and/or 602a can be used to monitor the operating parameter conditions within the hood 14 to determine if the operating parameter condition has been corrected so that the operating parameter condition is now below its operating condition parameter threshold.
