The present invention relates generally to the collection of data related to the dispensing of media used during the course of a number of medical procedures. In one alternative embodiment, the present invention relates to the collection and archiving of data from an injector system and/or extravasation detection device such that clinical personnel and/or medical imaging practice managers may more readily access information relating to usage statistics of the injector system and/or extravasation detection device. In one alternative embodiment, the present invention provides a medical device, including, but not limited to a system, method, and/or computer program product that may be integrated into a medical imaging suite and in communication with one or more injector systems, one or more computer networks, and/or one or more extravasation detection devices so as to allow, for example, the analysis of statistics related to the usage of media, the usage of the injector systems, the usage of disposable accessories used in a medical procedure, for example, syringe components and/or the usage of the extravasation detection devices over the course of a selected time period, for example.
Medical procedures, such as imaging procedures, often rely on the use of a media, such as contrast media, flushing media, or other liquid, solid, and/or gas media, that is dispensed and/or injected into the biological structure to be imaged such that the procedure provides more detailed information to a radiologist or other medical personnel responsible for analyzing the procedure results (such as medical imagery). Such medical imaging procedures may include, for instance, angiography, computed tomography (CT), ultrasound and/or NMR/MRI. The term “contrast media”, as employed herein, refers to essentially any suitable type of media, as used in the medical arts, that is injected into an individual and, in the context of a medical procedure such as, for example an imaging procedure (such as MR, angiography, ultrasound or CT), facilitates in highlighting selected areas of the individual's body while the individual is being scanned. In addition, the term “contrast media”, as employed herein, may also refer to other diagnostic or therapeutic agents for injection into individuals. The term “flushing media”, as employed herein, refers to essentially any suitable type of medium, such as a saline solution, that can be used to flush contrast medium, or other types of materials, from the tubing of an infusion system (or any other components thereof) and that is well-suited for flowing through the individual's body so as to serve a useful supplementary purpose such as, for example, keeping his/her veins open in preparation for another infusion of contrast media. Contrast media may be injected into an individual's vasculature prior to a medical procedure (such as, for example, a medical imaging procedure) by a dispensing device including, but not limited to a power injector having an electronic controller.
Some dispensing devices may include electronic controllers capable of collecting and storing information related to the usage and/or function of the dispensing device. For instance, in some cases, the dispensing device may create a data set containing, for instance, information regarding volumes of contrast media dispensed, time and date stamps for particular medical procedures including, but not limited to medical imaging procedures, information related to the dispensing pressure exerted by the dispensing device during a particular dispensing operation (such as, for example, the pressure profile for a powered injection of contrast media) and/or information regarding the usage of sterile disposables (including syringes or other accessories used by the dispensing device).
In addition, in some medical imaging facilities, the dispensing device may be in communication with an extravasation detection accessory (EDA) (such as the E-Z-EM Extravasation Detection Accessory (EDA®)), or other accessory device capable of detecting extravasation events in an individual undergoing a medical imaging procedure. Such accessories may include, but are not limited to, adhesive electronic sensors capable of being adhered to an individual's skin at the contrast media injection site (in procedures using a power injector, for example). The EDA may thus be capable of detecting changes in impedance at the injection site corresponding to an extravasation event (which may include, for instance, cases wherein contrast media is inadvertently released outside the targeted injection area (i.e., outside the vasculature of the individual). EDA devices may include embedded electronic components that may be in communication with the electronic controller of the dispensing device, such that an operator of the dispensing device may choose whether or not to enable the EDA during a given dispensing operation. In addition, the EDA may generate a data set during the course of its operation during a dispensing operation. For instance, an EDA may, in some cases generate a data set that may be stored either in its embedded electronic components, or sent to the electronic controller of the dispensing device for storage along with the dispensing device data. Such EDA data may include but is not limited to, time and date stamps, an indication as to whether or not the EDA was enabled, and indication of whether or not an extravasation event was detected during a given dispensing operation, and an impedance profile (over time) generated by the EDA as it is adhered to an injection site.
Dispensing devices used in medical imaging practices may be syringe-based power injectors (including the E-Z-EM Empower CT® and Empower CTA® power injector systems) that may include one or more syringes (containing pre-loaded amounts of contrast media and/or saline solution). In addition, such systems may be electronically controlled via electronic controllers that may be pre-programmed to administer a variety of contrast media either arterially or intravenously in conjunction with medical imaging procedures. In addition, such automated, powered dispensing devices may also be in communication with an EDA that is capable of detecting an extravasation event and logging such an event (along with the corresponding impedance profile generated by the EDA) in either an embedded electronic component or with the electronic controller of the dispensing device.
The data sets generated, processed, and/or stored by the dispensing device (and/or its electronic controller), the EDA, and/or other accessory devices used to dispense and/or monitor the dispensing of contrast media in a medical imaging suite are currently stored in a manner that they may be accessible by a technician servicing the device such that the technician may be able to determine various types of information, including but not limited to the usage statistics and or error codes of the device. The data sets may not be stored and/or organized in a manner that would allow the data included therein to be used effectively by clinical professionals and/or other professionals charged with managing a medical imaging practice. On the contrary, medical practice managers and medical staff have conventionally relied on manual record-keeping methods to record and/or log the usage of contrast media and/or other statistics related to the usage of a dispensing device and/or EDA within a medical imaging practice. Thus, clinicians must take valuable time to manually collect usage statistics that may already be stored (in a relatively inaccessible and/or unhelpful format) within the electronic components of the devices within the medical imaging suite. In addition, clinical practice managers must rearrange the raw data taken by clinicians in order to convert the dispensing device and/or EDA usage statistics into a format that may be useful, from a business perspective, for assessing the efficiency of the medical imaging practices. For example, the clinical practice manager is often tasked with identifying sources of waste and with predicting budgetary needs for a given time period (i.e., instances of pre-loaded, but unused contrast media, the excessive use of disposables, and/or excessive instances of extravasation events (which may signal that a dispensing device is malfunctioning and/or requires servicing or replacement)).
Thus, there exists a need for a device, system, method, and/or computer program product capable of collecting, storing, processing, and/or arranging data sets from a medical device, including, but not limited to, a dispensing device or other medical imaging accessory such that data within the data sets (i.e., usage data sets) may be effectively used by a clinical practice manager to monitor the usage of contrast media, dispensing device usage, EDA usage, the usage of various disposables, and other usage data related to the dispensing of contrast media within a medical imaging suite. Also, there exists a need for a device capable of communicating with a medical device, including, but not limited to, a dispensing device, and/or a method and corresponding computer program product capable of operating on an electronic controller of such device that may collect, arrange, process, store, and/or effectively present data related to the operation of dispensing devices in a medical imaging suite.

The data may also include, but is not limited to, procedure ID numbers, name of stored injection procedure (should actual procedure have be recalled from dispensing device memory), injection protocol (including, for example, phases, flow rates, volume, contrast media type and brand, and/or injection pressure profile, actual or achieved flow rates, actual injection procedure elapsed time, etc.).
According to some embodiments, the data collection device may be configured to be capable of collecting primary data from a dispensing device 115, EDA, 113, imaging device 117, a controller device (which may be in communication with one or more of the various dispensing 115, EDA 113, and/or imaging 117 devices located within a medical imaging suite 100), and/or a computer network 150 (which may be in communication with a database of patient histories and/or administrative data pertinent to a specific procedure and/or dispensing operation). Thus, in one alternative embodiment of the present invention, the data collection device 200 may be further configured to convert the primary data into summary data for use by a clinician and/or administrator. For example, in one embodiment, the primary data may include a number of one or more syringe load-fill-unload cycles arranged by date and time wherein the cycles do not correspond to a dispensing operation, which may correspond, in turn to a summary data point indicating a number syringe pre-filling operations (wherein the dispensing device 115 was used to pre-fill a number of different syringes or other consumable devices with contrast media and/or saline without dispensing the contrast media and/or saline to an individual). Furthermore, such primary data may also include, but is not limited to, a number of one or more syringe load-fill-inject-re-fill cycles arranged by date and time wherein the cycles to not correspond to a removal of the syringe, so as to indicate a summary data point corresponding to a syringe re-use (in, for instances, cases where the syringe was re-filled with contrast media for a second dispensing operation for the same individual).
The data collection device 200 may further be configured to be capable of processing, interrogating, and/or communicating with a computer network 150 of a hospital, medical imaging suite 100, and/or other medical facility such that the data collection device 200 may be further capable of communicating with one/or more medical devices such as, for example, imaging devices 117, imaging device controllers 122, computers 135 and/or other accessory devices that may be located within the medical facility as well as various databases that may be accessible via the network 150. In some cases, the network 150 may be further connected to the internet or to various intranets in order to allow remote access to the data collection device 200 and/or the data set (e.g., a usage data set) collected thereby according to the various device, method, and, computer program product embodiments of the present invention. In such cases, the data may further include, but is not limited to: one or more flow rates, volume, pressure, and programmed pause data corresponding to a dispensing operation; one or more protocol-identifying data corresponding to a pre-programmed dispensing protocol corresponding to a dispensing operation (as collected from one or more dispensing devices 115 in communication with the data collection device via wire or wireless methods and/or via a network 150); one or more individual-identifying and/or individual-specific data (such as patient history information as manually collected by a clinician or administrator using the user interface 230 or as automatically collected by the data collection device 200 via the network 150 from a computer 135 containing a database of patient information); and/or one or more imaging device data corresponding to a medical imaging procedure (as collected from an imaging device 117 or an imaging device controller 122, for instance).
According to various embodiments of the present invention, the computer 135 may receive one or more dispensing device data sets (e.g., usage data sets) from a corresponding one or more of dispensing devices 115 (that may be located in one or more medical imaging suites 100) connected to the network 150. Furthermore, some embodiments of the computer program product (operating on the dispensing device controller 210, for example) may also be executed in a like manner on a computer 135 (which may be co-located with the controller 210 and/or in communication therewith via network 150). Thus, a co-located and/or offsite computer 135 (operated by an administrator, for example) may access all display and operational features associated with the collection device 200, and also may comprise several additional features that may include, but are not limited to: features for automatically synchronizing data sets among the one or more dispensing devices 115 on the network 150 so as to maintain data in a updated format and so as to ensure data formats received from various dispensing devices 115 may be identical to one another; features for assigning user defined names to dispensing devices 115 for easy identification relative to a health care enterprise (for example, location names, code numbers, and/or suite room numbers); features for selectively displaying, editing, or manipulating data from the one or more dispensing devices 115 either individually, in user defined subset by user defined names or aggregate of all dispensing devices 115; features for retaining data sets on computer 135 for archival purposes; features for deploying generic application program interfaces to export dispensing system data to other commercially available generic word processing, spreadsheet and database applications.
Also, in alternative embodiments of the present invention, the data collection device 200 may be configured such that the controller 210 is capable of transmitting and/or receiving the extravasation data set comprising data related to the operation of a medical device such as an EDA 113 as part of a medical procedure, including but not limited to, a medical imaging procedure. Such data collected, processed, and/or stored as part of an extravasation data set may include, but is not limited to: a date of the medical imaging procedure; a time of the medical imaging procedure; an indication of whether or not the extravasation detection device was enabled; an indication of whether or not an extravasation event was detected; and/or an impedance profile corresponding to the detection operation.

Such a method embodiment may also comprise step 325, which includes, but is not limited to, directing the extravasation data set to the storage device 220 such that the extravasation data set is integrated with the usage data set selectively retained within the storage device 220. Here, the usage data set and extravasation data set collected as part of the method embodiments may contain data of the various types described above in relation to the data collection device 200 embodiments of the present invention.
In another alternative embodiment of the present invention, the method may further comprise additional steps, as shown generally in steps 330 and 335, for collecting a supplemental data set 330 from either a controller 122 configured to control and/or collect data from the imaging device 117 and/or a 135, and for directing the supplemental data set to the storage device 320 such that the supplemental data set is integrated with the usage data set selectively retained within the storage device 220. In some embodiments, as described above with respect to the data collection device 200 and system embodiments of the present invention, the supplemental data set collected as part of step 330 may be collected from a database and/or computer network 150 that may be in communication (via wired or wireless methods) with a computer 135. Thus, the supplemental data set may include, but is not limited to, data related to an individual patient history, insurance information, consumable device inventory information, and/or other data (including clinical site and/or medical imaging suite 100 identifying information) that may be stored in a database residing on a remote computer 135 and/or other electronic device in communication with the network 150. Thus, according to one alternative embodiment of the present invention, a clinical practice manager may access, review, process, and/or supplement the data within the supplemental data set and/or the more inclusive usage data set via a remote computer 135 located in a remote location such as an administrative office 130 (as shown schematically in

For instance, according to some embodiments, if the user were to touch the contrast button 910 an annual contrast utilization screen (ending with the current month) could be displayed in accordance with the executable portion of step 360, as shown generally in
In another alternative embodiment of the present invention, if the user selects a given month and subsequently a given day using the time/date button 400 (pressed once to select a given month, and again to select a given day), the computer program product (according to the executable portion of step 360 will display procedure-specific usage data arranged by the time of the procedure/dispensing operation on the selected day. Such usage data is thus specific to a given dispensing operation and represents procedure-specific usage data sets generated by the executable portion of step 340. The usage data collected for a given procedure may include the same data fields shown in items 420, 430, 440, and 450 as discussed above.
Alternatively, as shown in the navigation display shown in
The user may also navigate through the display of
In addition, as shown in the navigation display shown in
While the displaying executable portions of step 360 above are shown in terms of a touch-screen user interface 230 as discussed above, the data screens above may also be navigated by other means, including “point-and-click” methods (via a computer mouse, trackpad, and/or other methods that may be appreciate by one skilled in the art). Furthermore, in some embodiments, the user interface 230 may be in communication with a printer, monitor, or other electronic device suitable for displaying and/or printing the usage data collected and/or stored in accordance with the various methods of the present invention.
