CONTROLLED ENVIRONMENT OBSERVATION DEVICE

TECHNICAL FIELD

This invention relates to a device which provides for a controlled environment for the culturing and observation of biological specimens including embryos, oocytes and stem cells.

BACKGROUND

Currently, there are several known microscope type devices, which provide a means for observing biological sample. These known devices have a limited ability to take good images without the use of a manual-focusing device. These devices lack the ability to take highly accurate and repeatable pictures of embryos and send this information to a user. A problem with the current devices is that they mostly utilize manual focusing systems and which often takes a great deal of time to achieve a good focal imaging and is not readily repeatable.

An additional problem with current devices is that the components are often separate and not attached in such a fashion as to have the components a more exacting distance from each other. This may lead to the lense distance from the observation platform to vary and therefore doses not give the instrument the best repeatable images distance.

An additional problem facing current devices is that they may require several different magnification powers of the lenses in order to achieve the magnification of the images desired.

Some of the additional problems facing current devices are that they may not be able to move the imaging device with respect to the biological specimen to obtain proper images of the specimen. Therefore the dish or holding device must be manually moved about to find the specimen and obtain a proper and satisfactory image.

Another problem faced by current devices is that they are unable to obtain proper images for specimens that may roll or otherwise move.

Some current devices do not provide all the components necessary to give the embryos the best chance to survive and be the best for preimplantation. Some of the current devices are cumbersome, have a large amount of service requirements and are not consistent in their performance.

An additional problem faced by some current devices is that they have an inferior or inadequate filtering system to provide continual clean air for the biological specimen environment. The current devices do not have consistent methods for monitoring the Volatile Organic Compounds (VOC) and inform users on the timely replacing of the filters. The current devices may also lack the filter technology necessary to keep the air quality acceptable in the biological environment

Some current devices are cumbersome and heavy, and they have separate systems for the incubator environment and camera systems, which make the service and repair difficult.

Current devices often use flat bottom dishes or devices, which allow the embryos to be anywhere on the bottom of the dish, making imaging more difficult, does not allow flexibility in the magnification of the images, will allow the embryo to rest on the edges of the dish, which may distort its shape and appearance and does not allow the use of a large quantity of media, due to the limited well size of the dishes. Although a limited well size makes finding the embryo easier, smaller amounts of media will impede embryo development and may not allow the embryo to grow and culture properly.

A major problem of some current devices, is that they may have a ‘large box’ or larger holding stations and equipment configuration. These large box devices are typically assembled in the traditional manner of multiple parts being added to the ‘large box’ device. This creates difficulty in servicing the system due to the many parts in the ‘large box’ device, and the lack of modularity, such that one component cannot easily be replaced. Thus large box devices typically are very complicated to provide service and repair.

Another major problem of current devices is that they often comprise many moving parts, which need to work together in the field, but are difficult to service and repair.

Many current devices require an on-site service call by a qualified service repair person for any and all mechanical failures of the products. These disadvantages become more critical when considering the fact that the parts needed to repair the product may not be readily available for the immediate service needs and may need to be placed on order, shipped and then serviced, resulting in the unit being inoperative for an extended period of time, causing possible damage or death to the biological specimen.

Another major problem facing the current devices is that they typically use one camera and one mechanical system for multiple biological specimens such as embryos. This means that there may be up to nine different biological specimens in different dishes, or are separated by space within a single device. If the camera or any of the key mechanical systems fail to work properly the entire system cannot be used. This may result in the transportation of the patient embryos in one system to another system, or the user not being able to important features of the device such as taking photographs.

An additional problem of current devices is that the devices generally only have one system for providing incubation to the entire device. If this incubation system malfunctions, such as temperature, gas mixes or power malfunction, the entire unit may become useless as to the incubation function. This may result in loss of embryos, reduced growth of the embryos and the emergency transfer of all patient embryos to a second unit. The problem most clinics will face in this situation is the likelihood, they will not have a backup unit or a second unit with space to accommodate the transferring embryos and therefor the user must use a conventional incubator system, without the camera features and therefore not be able to take the desired images. The failure of the incubator system may result more significant problems such as the loss of embryos.

An additional disadvantage to the current devices is that they are generally built to accommodate a defined number of dishes and therefore limit the number of biological specimens that may be serviced at the same time in the unit.

A problem facing the other types of incubator systems, is that they may use indirect heating, which may not provide appropriate heating to the embryo environment.

Many of the existing systems do not contain any safeguards to keep unauthorized personnel from entering the software system and/or the hardware systems of the devices. Most existing systems do not restrict individuals from entering the software system and from entering the chambers or incubator portion of the device, which houses the embryos. In addition there also do not appear to be systems which will keep unauthorized personnel from making entries to the software.

In many existing systems, the user will use an older or lightly used standard incubator, which may be available, to pre-equilibrate dishes, media and oils. In most cases these already existing systems run on its own system of electricity, and gases. These electrical and gas system generally must be maintained separately.

Many of the products on the market today do not contain the feature of having separate chambers. Many products have a system where the dishes share the environment, gases and camera system.

The ability to take quality, timely images of the embryos has been a problem facing all the current systems. The other system encounters a problem with aligning with the exact location of the embryo when it is time to take an image.

Currently, most systems utilize a single dish or holding configuration for holding the embryos during the process.

Thus there is a need for a controlled environment observation device that overcomes the above listed and other disadvantages.

DETAILED DESCRIPTION

The disclosed device may provide a more accurate focusing on and imaging of biological specimens such as embryos, stem cells, and other biological specimens. The disclosed device will include at least one camera. In one embodiment the camera may be located below the biological specimen and may be moved by a mechanical system—an X,Y,Z camera system. The disclosed device may also comprise an onboard microprocessor to connect the components comprising the disclosed device. The onboard microprocessor may allow the invention to be independently operated and will allow the device to be more portable and replaceable.

The disclosed device may comprise an observation platform, a heated viewing surface, a mechanical X, Y and Z system, and a camera configured to view the underside of the observation platform. By being configured in such a fashion, it allows the camera to be located more accurately with respect to the specimen.

The disclosed device has a unique advantage in utilizing a concise XYZ system. Because the disclosed device is mounted to view the underside of the observation platform, it allows the Z component to move the camera up and down with respect to the observation platform, i.e. closer or further from the specimen.

The disclosed device comprises an incubated environment with the proper levels of CO², N²and oxygen for specimen growth, as well as a camera system, a component to hold culturing specimen dishes in place, the dishes containing a media solution, and an air filtering system for cleaning and recirculating the gases within the system. The disclosed device will include the incubated environment, at least one camera below the dishes which may be moved by a mechanical system, commonly known as an X, Y, Z system, for the accuracy of the images and for the taking of images of the embryos, and an onboard microprocessor to connect the device to equipment for the monitoring and viewing of these images. The onboard microprocessor allows the device to be independently operated and will allow the device to be more portable and replaceable. The specimen dishes will generally have an optically transparent bottom, so that the specimen in the dish can be visible from below the dish.

The disclosed device may be used for placing the specimens in a conventional petri dish or a unique culturing holding device or dish. Placing these dishes in their designated holding areas will allow a camera to take images of the specimens, from underneath at desired time intervals. The dish and the platform may contain a unique keying system to assure that the dish and the specimens within are in the same viewing location on a repeated basis.

The disclosed device may include a camera which may be auto or self-focusing and/or a manually focused camera.

The disclosed device may include an automated locating system for the precise observation and imaging of the desired specimens and a joy stick′ feature, which will allow the user to easily move a camera with respect to a dish or container and locate and observe desired specimens.

The disclosed device may have connectors for incoming gases, electrical input and monitoring and may be constructed to be portable. The disclosed device may be configured to be integratable into a larger system or several systems.

The disclosed device may include probes and sensors to obtain data used to report and validate the performance of the ongoing systems, such as particulates in the atmosphere, monitoring volatile organic compounds (VOC), PH measuring devices, mouse embryo assay testing capabilities and environment evaluations. The disclosed device may maintain acceptable levels of air quality and may provide data to inform the user that conditions are optimal for embryo culture.

The disclosed device may provide the user with images of each embryo, at predetermined time intervals to provide the user with a better understanding of the development of each embryo, to give the user a better idea of which embryos may be a better embryo for implantation, cryopreservation and or such. The disclosed device may provide a complete environment to culture the embryos for a period from about the first day through about blastocyst or about implantation into the patients, which in most cases are about 5 or 6 days. The disclosed device may provide a superior culturing system, along with information, and images that will ultimately allow for better embryo selection, embryo implantation and a better chance of a live birth.

The disclosed device may use various numbers of biological specimen chambers. The disclosed device may be configured to accommodate about 4, about 6, about 8, about 12, and any number of chambers in the main device, and therefore may be able to accommodate more biological specimens at the same time.

An additional advantage of the disclosed device is that the disclosed device may comprise modules, and the modules of the disclosed device may be easily swapped out for repairs and/or replacement.

The disclosed device may contain a location system, a camera system, a controlled environment of temperature and gas levels, along with a uniquely designed dish to hold the embryo in place for imaging. The disclosed device may have the ability to take images at designated and at specific time intervals; and to utilize an embryo culture media which will allow the uninterrupted culturing of the specimen; and an air filtration device for incoming air and recirculate gases, which will provide the enclosed environment with greater reduction of particulate, VOC's and CAC's. The disclosed device may also include a dual air filter system.

The disclosed device may provide a consistent temperature for the biological specimens of about 37 degrees Celsius at all times.

The disclosed device may contain a temperature controlled environment, where the temperature is maintained at about 37 degrees Celsius, and the environment may be humidity free or contain a prescribed humidity. The amount of humidity in the environment may be determined by the impact it may have on the cleanliness and/or fogging of the windows the camera view through and the preference of the users as well as any impact on the biological specimens.

The disclosed device may comprise a power source, incoming gases necessary for the biological specimens, connectors for transmitting images and electronic signal communication with the various components of the disclosed device. The disclosed device may comprise a controlled environment volume, such as chambers or modules. These chambers or modules may maintain a temperature-controlled environment for the biological specimens, with incoming gas ports and a camera system for taking images of the specimens. The disclosed device may comprise gas input ports for the exchange and monitoring of the environmental gases. The disclosed device may include an environmental air filtration and purification system. The disclosed device may use unique combinations of heating, temperature controls, imaging mechanisms, and incoming gas systems, along with certain air flow techniques and HEPA/VOC filters to more effectively clean and maintain a very clean incubated environment for the biological specimens. Images are to be taken from underneath the dish, with a camera system, which may be moved to facilitate the taking of images at specific locations and times.

The disclosed device may also comprise a computer system configured to view and take images of the biological specimens, configured to move the camera, control and display important parameters related to the biological specimens including and not limited to the internal temperature of the disclosed device, internal temperatures of the biological specimen containers, gas levels, such as CO², N²and oxygen.

The disclosed device may comprise a display screen. The display screen may be used to show each patient embryo in a sequence selected by the user. The embryos may be shown at specifically selected time intervals, metabolic stages and at any other times or stages selected by the user. The system will allow the user to compare past and present embryos of the patient, the program and the clinic.

In one embodiment of the disclosed device, the disclosed device may comprise an incubated environment, which may be a generally humidity free or low humidity environment. This environment allows the cameras to take better images of the specimens, because their will be little or no moisture to adversely affect the image taking capability of the disclosed device.

Another embodiment will allow the embryos to be maintained in a humidified environment and the cameras/scope to be outside of that environment and itself in a dry humidity environment. Using a humidified environment will not dry out the embryo's environment. A specially designed specimen dish will allow the embryos to be cultured in both environments, by providing an ample amount of media and will allow for an oil overlay, which has a tendency to keep the media from evaporating and/or helps to maintains a consistent temperature.

An additional embodiment of the disclosed device is that it may be constructed in such a way that the disclosed device may contain many dishes in a single chamber, where the camera moves beneath the dishes and will be able to move to position itself at the exact location where it will take pictures. The dishes and camera may be within the same chamber device.

The disclosed device may have the ability for a specimen chamber to be affixed to an external device, away from the base unit for a period of time, to allow the user to perform various testing procedures or observations. This external device will support the functions of the main unit, during this time.

The disclosed device is has a unique advantage over the competition in that it can incorporate devices and technologies into a far more effective and reliable system for the culturing of embryos. The combination of these devices along with addition of unique key features within this disclosed device, establishing a stand-alone, more complete incubation and maturation device for the purpose of long-term uninterrupted embryo culture.

The disclosed device may contain a unique combination of metals, glass or plastic on the bottom of compartments, where the dish is held. This combination of materials will overcome the problems of maintaining a consistent heat across the bottom of the dish well, and therefore maintain a consistent heat across the bottom of the entire dish, which will result in a constant temperature for the media and oil within the dish and therefore maintain a constant temperature for the embryos to develop in. The ability to maintain a consistent heat across the base of the dish and its content will result in a significant benefit of the disclosed device and will increase the chances of better embryo development and a great success rate.

The dish holding area may be a combination of glass, plastic, metal or a composite, that allows specific areas of the bottom to be clear, allowing the camera to be able to take the images from underneath the dish. The glass or plastic bottom will be integrated with a containment ring or system, which will be replaceable, and changes in and out to allow different dish configurations, changeable if the surface gets scratched. This containment system will insure that the dish aligns with the camera each time to allow imaging. The bottom will contain a combination of the glass and or plastic and a portion of a metal material around and/or across the bottom of the dish holding area.

The metal and composite material may contain a crossing pattern on the bottom of the holding area which will assist in applying a consistent heat in the bottom component, which will maintain a consistent heat across the bottom of the dish, and transfer this heat to the dish, media and oils within the dish.

The disclosed device may include an interchange dish holding component. The interchange dish holding component may be designed to be inserted into the incubator assembly and to be removed and changed to match a particular dish′ heating requirements or when the glass or plastic, of which the images are taken through may become scratched or damaged. The component will be able to meet the heating requirements and the dish configurations to provide the most effective heating available and to meet the needs of the specimens. The bottom of the holding component may become scratched or discolored and may be in need of changing. The interchange dish holding component will allow the disclosed device to be more versatile for the future developments of dishes, material and the needs of the users.

The embryos need to be safely contained against entry by unauthorized personnel. Thus, the disclosed device may contain a combination of security system such as a fingerprint recognition system, key system or keypad entry systems. The recognition system will be used to only allow authorized personnel for access to the software, make changes and the entry into the chambers holding the embryos.

The chambers or the module may be locked closed until such time as an authorized user unlocks the chambers or module. The locking mechanism may be of a mechanical nature, may be a magnetic locking system, may be an electronic locking system, or any suitable locking system currently available depending on the individual requirements of the uses. The locking system will contain safeguards allowing an override of the locking system in case there is a problem with the locking system—such as a loss of electrical power or mechanical failures.

The chamber or module may be used individually or in combination with other chambers; in a larger holding device which will hold 6, 9 or 12 chambers. Each chamber may be an individual chamber or module enclosure to hold the embryos for growth and maturation. The chamber will contain a separate embryo holding component within which will hold the embryos, maintain an accurate and consistent heat for the embryos, gas input channels and the ability to view and take images of the embryos from below.

The chamber is designed to segregate the embryos and to maintain an optimum environment to maintain the proper embryonic development for each embryo while allowing images to be taken of the embryos over an extended period of time, in order to choose the most likely embryos to implant and then result in a live birth.

An additional advantage of the disclosed device are and the separate chambers, which allows the user to remove from the disclosed device a device a single dish from a single chamber, to perform other types of testing such as pre-implantation genetic diagnosis (PGD), intra-cytoplasmic sperm injection (ICSI) or any additional types of analysis or testing, without impacting any of the other chambers, or the dishes, and/or samples within. This feature will additionally allow the removal of a single dish without impacting the environment of the other chambers.

The dishes used, may be those designed to allow the embryo to settle at the bottom, middle of the wells, within the dish. This allows this disclosed device to include a more compact system for the cameras to locate the embryo for imaging. The fact that the embryo rests in the bottom middle of the dish keeps the embryos from settling against the well walls, which may distort the embryo, may not allow adequate viewing of the embryo to allow the finding such key features, such as the embryos spindle.

An additional significant advantage of these unique dish holding areas and the dishes used is that they contain a center and the imaging focal point for the camera to focus on and find easily, but also allow for better-magnified images, and the use of more and greater levels of magnification. Imaging can be taken through the bottom of the dish.

The camera system may have the ability to articulate in order to take images at multiple angles to capture 3D image information, which will be assembled by the system to produce a 3D image for the end user. The 3D imaging will allow the end-user more information and allow them to locate and monitor additional features of the embryos, which may not be visible when taken in a single angle, such as cell development, nuclei and the like.

An additional advantage of the disclosed device is it allows the collection of images at key intervals of development. Imaging will be taken and collected to be used in a determined sequence of images for the evaluation by the user or embryologist. This timed sequencing and maturation sequential will be used to monitor the growth levels and the development of the embryos.

The disclosed device will allow the user to observe and annotate and describing the maturation of a human embryo. This will also allow the comparison of these images to the prior images of same embryos, other embryos of the patient, and embryos from past successful treatments for this clinic or laboratory. The images will be sequenced in a collection of the images in a useful collection for comparisons. These sequences and comparisons of those in times, morphological development and other sequences desired by the user to determine which embryos to be used in implantation or cryopreservation.

The disclosed device will take the images at planned and timely intervals, which may be at intervals of any combination of minutes or hours. The intervals of the images may be adjustable by the user to the frequency they find most effective for their protocols, practice and clinic.

The time intervals and sequences used in the disclosed device will take into account the possible harmful effects that the light used may have on the embryos and their development. Our studies have established the useful light colors and wavelengths for the system, as well as to produce enough light for clear and effective imaging.

The culture media to be used in the disclosed device may be consistent with the media solution used for extended and uninterrupted embryo development. The embryos may be matured from the retrieval, referred to as day “0”; they then may be cultured through to blastocyst development or Day 5 or 6. These embryos have a better chance of implantation and eventual live birth, after they have been matured to the blastocyst stage. This media is consistent with the current media products, trade named Global®, which is a proprietary media solution of the assignee.

The disclosed device will allow the use of a multiple number of medium solutions and protocols.

The disclosed device incorporates a complex system to maintain the temperature of the embryos. The system includes a heating system for the platform for all the chambers and each chamber, as well as temperature reading probes throughout the disclosed device to assure that the temperature are what is need and what is being reported.

The device may include incoming gas ports for the control of the CO², N²and oxygen levels, injector ports and control mechanisms. The disclosed device may include its own gas mixer and sensors for adjusting the gas levels as needed.

The disclosed device is a combination of the described incubator filters and may include at least one motor in the device to provide consistent airflows, air velocities and air exchanges.

The disclosed device may contain a unique system for monitoring the volatile organic compounds (VOC) and particulates levels within the environment on a consistent basis. By reading and monitoring the VOC's, this will allow continual usage of the device while knowing that the environment is correct. Current devices do not include this feature, but rely on the replacing of the air filters in timely basis to insure clean air. These filters may be not working to the full capacity during this time due to loading factors and not having a constant monitoring system.

The disclosed device may include a mechanism to provide a vibration within the device, at planned intervals. This vibration effect has multiple purposes in the process for the improvement of the embryonic development. One accomplishment of the vibration system is to vibrate certain surfaces, the dish or entire device, thereby vibrating the dish. This vibration will allow the consistent mixing of the media solutions, which the embryos are culturing in. The vibration mechanism may create a vibration which can mimic the mother's natural motion, which the embryo would experience through the 5 or 6 days of normal maturation if within the mother's body.

Another importance of the vibration system is to vibrate the dishes and allow the embryos to drift to the bottom of the uniquely designed dishes. This will allow the embryos to be at the center of the dish, at the focal point so that the camera is able to focus on the exact spot the embryo is sitting within the dish for imaging

The disclosed device will have the capacity to provide audio signals and sounds, as well as listen to the any sound within the device. The options may be sounds such as a heartbeat, music, etc.

In addition, the ability to detect sound or motion within the dishes is to alert the system as to any movement by the specimens within the dishes. Embryos as they mature, expand, grow, roll and change shape. The ability to detect such changes would allow the system to alert the camera system, to take key images at embryonic developmental stages. The disclosed device will use this information to coordinate the images with the key morphological changes, such as 2-cell split, 4 cell split, compaction and 8-cell split.

The disclosed device includes a unique feature, which will allow the user to select the dish type they want to use, and the system will provide chooses to recognize the different dish configurations and set up the positioning for the images to be taken for the configuration of each particular dish.

The ability to select the dish type allows the dishes used to be specific for the different needs of the user. To illustrate this embodiment, in one example a dish may contain many smaller wells which may contain fewer amounts of culture media, of approximately 100 microliters of media in the well. A second user may desire to use more media, of up to 300 microliters per well, which would require larger wells, which may position the wells differently in each dish configuration.

The user may at times wish to perform different procedures or protocols and therefore require a different dish and set procedure, which will require different timing intervals, types of images and overall different treatment. The disclosed device will be able quickly adjust to the different dish in the wells and may use a combination of dishes at the same time, in the multiple chambers. This may be accomplished by the user using different modules with different features for the various types of dishes.

The disclosed device may include a separate preliminary chamber to be used to place items into prior to the entry into the main chambers. The use of the preliminary chamber may be to equilibrate media solution prior to use, to obtain the proper pH levels, for the equilibration of pre-prepared dishes and culturing devices, providing a warming feature and media pH equilibration, the temporary holding of specimens prior to the use, and/or to hold certain specimens while the user may be handling a portions of the specimens separately. This preliminary chamber may comprise one chamber, or several chambers. The preliminary chamber(s) may be separate larger chambers than the main chambers used for the embryos.

The preliminary chamber allows the user to place an item into this portion of the disclosed device, whereby it will share the same environmental conditions as the rest of the specimens. This means that specimens will be able to be pre-conditioned to the same balance of gases, temperature and overall environmental conditions. This will likely make the specimens placed into the main chamber more compatible to the environment. The addition of the preliminary chamber (s) also allows a scale of economics, as it shares the same electricity, gases and temperature, which will reduce the costs incurred as opposed to providing a separate incubation unit for the same purpose.

The disclosed device includes the above features in a single device, for the uninterrupted culturing of embryos, which will sustain the maturation, and growth of embryos, from retrieval through to implantation or cryopreservation. The disclosed device may comprise a sealed incubated area, a camera system for imaging and sequencing screens, a vibration system, and an air filtering and recirculating filter system allowing the embryologist to better choose the more viable embryos which will increase the chances of implantation and the likelihood of a live birth.

The disclosed device may provide for the long-term uninterrupted maturation of embryos through to the stage of development desired by the user providing the proper amount of CO², N²and oxygen.

The disclosed device may provide a concise sequence of images of the embryos during development, which will allow the embryologist to better select a viable embryo.

The disclosed device may provide a favorable clear environment by including an effective air filtration system to remove particulates and VOC's from the incubated environment.

The disclosed device may provide an improved device for the long-term uninterrupted maturation of embryos, which contains a real time monitoring system for the key indices such as pH, levels, CO², N², air quality and other key items.

The disclosed device may provide a single device which may be used separately to mature embryos, which will include all the featured needed, such as an incubator section, gas input and the ability to take images at desired times.

FIG. 1 illustrates the disclosed device 10. The device 10 is a controlled environment for the long-term maturation and imaging observation of embryos. The device 10 has a body 12 with a cover 13, handle on the cover 15, hinges 14 and seal 16 between the body 12 and the cover 13. The exterior body or walls 12 of the device 10 may include insulation to help control the interior temperature of the device 10 and the environment within the device 10. The device 10 contains a heated shelf 30, which is designed to hold the embryonic chambers 32. The shelf 30 may maintain a temperature of about 37° Celsius, holds the embryonic chambers 32 in place, and helps transfer heat to the chambers 32 and separates the upper and lower volumes of the device.

The exterior body or walls 12 of the device 10 may include insulation to help control the interior temperature of the device 10 and the environment within the device 10. The device 10 contains a heated shelf 30, which is designed to hold the embryonic chambers 32. The shelf 30 may maintain a temperature of about 37° Celsius, holds the embryonic chambers 32 in place, and helps transfer heat to the chambers 32 and separates the upper and lower volumes of the device.

The device 10 has incoming gas ports 22 and electrical input connectors 24, and a communication/data port 26. The incoming gas is for the embryonic development, and comprises of CO2, N2 balanced with O2. The incoming gas travels through these ports and then distributed to the chambers. The electrical connections 24 are for providing power to the device 10, and components within the device 10. The communication/data port may be used for the exchange of information of the device 10 such as temperatures, pH readings, gas level reading, air quality readings, images and the like. The input lines for of gas 22 and electrical 24 will be attached to the chambers 32 for gas and electrical needs of the chambers. The chambers 32 will be explained in greater detail below.

In the front portion of the device 10 a display screen 40 is located. The screen 40 may permit the user to set and program information for the chambers 32, timing matters, and may be configured to show images of the embryos in each chamber. The screen 40 may allow the monitoring of each of the chambers 32 and the embryos within (not shown). The screen 40 may be configured to allow users to select the images to be reviewed from these chambers. The screen 40 may present the pertinent information such as temperatures, pH readings, and timing matter to the users. The device may have a security means 42, which in one embodiment may be a security entry system, such as, but not limited to a keypad, or finger print recognition system.

FIG. 1 also shows a cutout 33. Each of the embryonic chambers 32 will have its own cutout 33 that it sits in. The cutout 33 allows the chambers 32 to be viewed from beneath the shelf 30. One of the embryonic chambers 34 is shown with its lid open 38. The device may contain an air purification system (not shown) to purify incoming air and to recirculate air within the device.

The device 10 may have adjustable legs 20, which may allow it to be adjusted, leveled, and may be used for anti-vibration purposes.

FIG. 2. Shows a cross-sectional view of the chamber 32. The chamber comprises a cover lid 52, which has an airtight seal 58. The chamber comprises four outer walls 54. The walls have an upper ledge 56. The ledge 56 provides a surface where the chamber 32 can hang from the heated shelf 30. This configuration allows the chamber to support a consistent temperature, gas content and environmental conditions when installed in the device 10. The upper section 60 of the chamber 32 is positioned to be adjacent to the plane containing the heated shelf 30. In one embodiment, the upper section 60 may be domed shaped. This configuration of the embryonic chambers will help to maintain a constant temperature, in one example 37° Celsius—the suggested temperature for embryo culture. The chamber 54 walls and the heated shelf 30 may be made of material with good heat transfer properties, such as, but not limited to: stainless steel, aluminum, etc.

The embryos may be held in the incubated volume 60 of the chamber 32, in the specimen dish 64. The chamber 32 may be supplied with a proper mixture of gases, such as but not limited to CO²and N².
