It is important for hospitals and other medical facilities to track the use of medical instruments, such as surgical instruments used in surgery. Some example medical instruments may include screws, forceps, scalpel blades, retractors, and other medical instruments. In some examples, hospitals may attempt to track the locations and times at which medical instruments are used and stored. This may assist in allowing a determination of an appropriate cost for use of the medical instruments. Medical instruments are often stored in a sterilization case, which is used to store and sterilize the medical instruments after use in a surgical or other medical procedure. Some existing techniques for tracking the use of medical instruments may include having an employee operate a scanner to scan a bar code or other identifier of the medical instruments and/or the case in which they are stored, but this may require extra steps that reduce efficiency and complicate procedures.
Medical instruments may be sterilized in a sterilization case by implementing an autoclave sterilization process, in which the medical instruments and the sterilization case may be subjected to high temperatures and pressurized steam, which may damage or degrade electronic components. For example, exposing an active battery (i.e., a battery that is in the act of supplying power to another component) to the high temperatures and pressurized steam of an autoclave process may drain the battery more quickly than normal temperature and pressure conditions.
Techniques for medical instrument sterilization case tracking are described herein. Medical instruments, such as surgical instruments used in surgery, may be stored in a sterilization case, which is used to store and sterilize the medical instruments after use in a surgical or other medical procedure. Some example medical instruments may include screws, forceps, scalpel blades, retractors, and other medical instruments. Medical instruments may be sterilized in the sterilization case by implementing an autoclave sterilization process, in which the medical instruments and the sterilization case may be subjected to high temperatures and pressurized steam.
A tracking component may be attached to the sterilization case. The tracking component may be battery-powered and may collect, store and transmit usage information associated with the sterilization case. In some examples, the usage information may include information such as a count of autoclave processes that are performed on the sterilization case, durations of time periods between autoclave processes, and a duration of a time period between a most recent autoclave process and a time at which the usage information is obtained from the tracking component by an external device. The usage information may be transmitted periodically, such as at repeating intervals, for example every few minutes while the tracking component is powered-on. In some examples, the usage information may be transmitted using a short-range wireless communications protocol. The usage information may be transmitted from the tracking component to an external device, such as a smart phone or other computing device. The external device may include location-based services, such as global positioning system (GPS) services, which may be used to determine the location of the external device. In some examples, because the tracking component and the external device may communicate via a short-range wireless communications protocol, the location of the external device may be assumed to be identical or almost identical to the location of the sterilization case. The location of the sterilization case at the time that it transmits data to the external device may therefore be determined based on the location of the external device. In some examples, after being received by the external device, the usage information may be re-transmitted to other components, such as cloud-based or server-based services, for further computation and analysis.
As described above, the tracking component may be battery-powered. The battery may be connected to the tracking component to supply power to the tracking component. In some examples, the battery may also be temporarily disconnected from the tracking component to temporarily stop the supply of power to the tracking component. In some examples, the supplying of power to the tracking component may be temporarily stopped (e.g., interrupted) during autoclave processes of the sterilization case, such as by disconnecting the battery from the tracking component or otherwise stopping the supply of power to the tracking component. As the high temperatures and pressurized steam of autoclave processes may drain an active battery, the lifespan of the battery may be elongated by deactivating the battery during the autoclave processes. It is noted, however, that, because the tracking component may be powered-off during autoclave processes, the tracking component may be unable to track the exact lengths of the autoclave processes. In some examples, the starting and ending of an autoclave process may be determined by a temperature sensor, such may be included in a hardware temperature switch or other switching component, that may also be attached to the sterilization case. Specifically, the temperature sensor may detect when the temperature of the sterilization case rises above a particular temperature threshold indicating a start of the autoclave process, and the switching component may then disconnect the battery from the tracking component or otherwise stop the supply of power to the tracking component. Additionally, the temperature sensor may detect when the temperature of the sterilization case falls below a particular temperature threshold indicating an end of the autoclave process, and the switching component may then reconnect the battery to the tracking component or otherwise resume the supply of power to the tracking component.
In some examples, the usage information may be used to determine times at which one or more autoclave processes are performed. For example, the usage information may include a first duration of a first time period between a completion of a most recent autoclave process and a time at which the usage information is obtained from the tracking component by an external device. In some examples, the time at which the most recent autoclave process is completed may be determined by subtracting the first duration of the first time period from the time at which the usage information is obtained. Also, in some examples, because the tracking component may be powered-off during autoclave processes, the exact times of the autoclave processes may be unknown and may instead be estimated, such based on average durations of autoclave processes that may be measured over time. An estimated autoclave process duration may then be used to estimate times of other autoclave processes preceding the most recent autoclave process. For example, a time of a completion of an autoclave process may be determined by subtracting, from the time at which the usage information is obtained, the estimated autoclave process duration for each intervening autoclave process and the measured time durations that are tracked before each intervening autoclave process and after the most recent autoclave process.
The foregoing summary, as well as the following detailed description of the preferred embodiments of the application, will be better understood when read in conjunction with the appended drawings. For the purposes of illustrating the methods and/or techniques of orthopedic fixation with imagery analysis, there are shown in the drawings preferred embodiments. It should be understood, however, that the instant application is not limited to the precise arrangements and/or instrumentalities illustrated in the drawings, in which:
Techniques for medical instrument sterilization case tracking are described herein. Referring now to
Some example medical instruments 105 may include screws, forceps, scalpel blades, retractors, and other medical instruments. Medical instruments 105 may be sterilized in the sterilization case by implementing an autoclave sterilization process, in which the medical instruments and the sterilization case may be subjected to high temperatures and pressurized steam.
As also shown in
The tracking component 113 includes a transmitter 116 that transmits the tracked usage information. The usage information may be transmitted periodically, such as at repeating intervals, for example every few minutes while the tracking component 113 is powered-on. In some examples, the usage information may be transmitted using a short-range wireless communications protocol, such as the BLUETOOTH® protocol. The usage information may be transmitted from the tracking component 113 to an external device 120, such as a smart phone, tablet or other computing device. The external device may include location-based services, such as global positioning system (GPS) services, which may be used to determine the location of the external device 120. In some examples, because the tracking component 113 and the external device 120 may communicate via a short-range wireless communications protocol, the location of the external device 120 may be assumed to be identical or almost identical to the location of the sterilization case 100. The location of the sterilization case 100 at the time that it transmits data to the external device 120 may therefore be determined based on the location of the external device 120 at that same time. For example, the location of the sterilization case 100 at the time that it transmits data to the external device 120 may be determined to be identical or almost identical to the location of the external device 120 at that same time. In some examples, after being received by the external device, the usage information may be re-transmitted to analysis services 130, such as cloud-based or server-based services, for further computation and analysis.
As described above, the tracking component 113 may be powered by battery 111. The battery 111 may be attached to the sterilization case and may be connected to the tracking component to supply power to the tracking component 113. In some examples, the battery 111 may also be temporarily disconnected from the tracking component 113 to temporarily stop the supply of power to the tracking component 113. In some examples, the supplying of power to the tracking component 113 may be temporarily stopped (e.g., interrupted) during autoclave processes of the sterilization case 100, such as by disconnecting the battery 111 from the tracking component 113 or otherwise stopping the supply of power to the tracking component 113. As the high temperatures and pressurized steam of autoclave processes may drain an active battery, the lifespan of the battery 111 may be elongated by deactivating the battery 111 during the autoclave processes. It is noted, however, that, because the tracking component 113 may be powered-off during autoclave processes, the tracking component 113 may be unable to track the exact lengths of the autoclave processes. In some examples, the starting and ending of an autoclave process may be determined by a switching component 112, that is also attached to the sterilization case 100.
The switching component 112 may deactivate and reactivate the battery 111 based on the starting and ending of an autoclave process. In some examples, the switching component 112 may be a hardware temperature switch that connects and disconnects the battery 111 to and from the tracking component 103 based on the temperature of the sterilization case 100. Specifically, the switching component 112 may include a temperature sensor 117, which may detect when the temperature of the sterilization case rises above a particular temperature threshold indicating a start of the autoclave process, and the switching component 112 may then disconnect the battery 111 from the tracking component 113 or otherwise stop the supply of power to the tracking component 113. Additionally, the temperature sensor 117 may detect when the temperature of the sterilization case falls below a particular temperature threshold indicating an end of the autoclave process, and the switching component 112 may then reconnect the battery 111 to the tracking component 113 or otherwise resume the supply of power to tracking component 113. In some examples, the temperature sensor 117 and/or switching component 112 may include a creep action thermostat and/or thermal protector, such as may include conductive bimetal construction. Also, in some examples, the switching component 112 may be calibrated to open or curl enough to break contact at different temperatures. For example, in some cases, the switching component 112 may be calibrated to open or curl enough to break contact or otherwise disconnect the battery when the switching component 112 detects an increase to a temperature that is indicative of a start of an autoclave process. In one specific example, an increase to a temperature of one hundred degrees (Fahrenheit) may be determined to be indicative of a start of an autoclave process. However, other temperatures may also be used. Additionally, in some examples, the switching component may be calibrated to close or resume contact or otherwise reconnect the battery when the switching component detects a decrease to a temperature that is indicative of an end of autoclave process, such as a decrease to one hundred degrees (Fahrenheit) or below. The term detect, as used herein, refers to a component sensing or otherwise being exposed to a temperature or other condition that causes, or results in, the component performing an action (and/or assuming a state) based on the condition. For example, the switching component 112 detecting a temperature that indicates a start of autoclave process refers to the switching component 112 sensing or otherwise being exposed to a temperature that causes the switching component to perform an action (and/or assume a state) based on that temperature (e.g., curling or otherwise disconnecting the battery from the tracking component). There is no requirement that the switching component 112 must be aware of a temperature or other condition that it detects. For example, there is also no requirement that the switching component 112 must display a temperature reading or otherwise report or keep a record of a condition that it detects.

At operation 212, an initiation condition is detected that is indicative of an initiation of an autoclave process that sterilizes medical instruments in the sterilization case. In some examples, the initiation condition may be an increase in the temperature of the sterilization case, such as an increase above a threshold temperature indicative of an initiation of an autoclave process. In some examples, this threshold temperature may be determined based on a history of measuring temperatures of sterilization cases at, or shortly before or after, the initiations of autoclave processes. Operation 212 may be performed by a switching component, which may include a temperature sensor for detecting a temperature of the sterilization case.
At operation 214, the supplying of power to the tracking component is stopped (i.e., interrupted), such as based on the initiation of the first autoclave process. As described above, the supplying of power to the tracking component may be stopped by disconnecting the battery from the tracking component or otherwise preventing the flow of power from the battery to the tracking component. Operation 212 may be performed by a switching component, which may include a switch for disconnecting the battery from the tracking component or otherwise preventing the flow of power from the battery to the tracking component.
At operation 216, a completion condition is detected that is indicative of a completion of the autoclave process. In some examples, the completion condition may be a decrease in the temperature of the sterilization case, such as a decrease below a threshold temperature indicative of a completion of the autoclave process. In some examples, this threshold temperature may be determined based on a history of measuring temperatures of sterilization cases at, or shortly before or after, the completions of autoclave processes. Operation 216 may be performed by a switching component, which may include a temperature sensor for detecting a temperature of the sterilization case.
At operation 218, the supplying of power to the tracking component is resumed, such as based on the completion of the first autoclave process. As described above, the supplying of power to the tracking component may be resumed by reconnecting the battery to the tracking component or otherwise resuming the flow of power from the battery to the tracking component. Operation 218 may be performed by a switching component, which may include a switch for connecting the battery to the tracking component or otherwise resuming the flow of power from the battery to the tracking component. At operation 220, operations 212-218 may be repeated for each consecutive autoclave process.
At operation 222, the usage information that is tracked and stored by the tracking component is transmitted to an external device that is external to the sterilization case, such as a smartphone, tablet or other mobile device. As described above, the usage information may be transmitted periodically by the tracking component, such as at repeating intervals, for example every few minutes while the tracking component is powered-on. It is noted, however, that while the usage information may be transmitted periodically at repeating intervals, there may not always be an external device within range of the tracking component that has a connection to the tracking component. Thus, not all transmissions of the usage information will actually be successfully received by an external device. In some examples, the usage information may be transmitted using a short-range wireless communications protocol, such as the BLUETOOTH® protocol. As described above, the usage information may include information such as a count of autoclave processes that are performed on the sterilization case, durations of time periods between consecutive autoclave processes, and a duration of a time period between a most recent autoclave process and a time at which the usage information is obtained from the tracking component by the external device. As also described above, in some examples, after being received by the external device, the usage information may be re-transmitted to analysis services, such as cloud-based or server-based services, for further computation and analysis.
In some examples, the tracking component may detect that the usage information has been obtained by the external device, such as by having the tracking component receive a return signal from the external device that confirms receipt of the usage information by the external device. In some examples, when the tracking component detects that the usage information has been obtained by the external device, such as via receipt of the return signal from the external device, the tracking component may delete or clear the usage information that is stored in memory, thereby allowing additional space for future usage information to be written into the memory.
At operation 224, the location of the sterilization case is determined. As described above, in some examples, the location of the sterilization case may be determined based on the location of the external device when the external device obtains the user information from the tracking component. Specifically, in some examples, the external device may include location-based services, such as global positioning system (GPS) services, which may be used to determine the location of the external device. In some examples, because the tracking component and the external device may communicate via a short-range wireless communications protocol, the location of the external device may be assumed to be identical or almost identical to the location of the sterilization case. The location of the sterilization case at the time that it transmits data to the external device may therefore be determined based on the location of the external device at that same time. For example, the location of the sterilization case at the time that it transmits data to the external device may be determined to be identical or almost identical to the location of the external device at that same time.
At operation 226, a quantity of autoclave process performed on the sterilization case is determined. In some examples, this quantity may be determined based on the tracked usage information, such as by software executing on the external device and/or at the analysis services. As described above, as part of the tracked usage information for the sterilization case, the tracking component may track and store a quantity of autoclave process performed on the sterilization case. As described above, in some examples, the usage information stored by the tracking component may be deleted and overwritten each time that the usage information is successfully obtained by an external device. Thus, in some examples, the quantity of autoclave processes tracked and stored by the tracking component may be a quantity of autoclave process performed on the sterilization case since a previous time that the usage information was successfully obtained by an external device, causing the quantity count to be deleted and overwritten.
At operation 228, times of autoclave process performed on the sterilization case are determined. In some examples, these times may be determined based on the tracked usage information, such as by software executing on the external device and/or at the analysis services. For example, the usage information may include a first duration of a first time period between a completion of a most recent autoclave process and a time at which the usage information is obtained from the tracking component by an external device. In some examples, the time at which the most recent autoclave process is completed may be determined by subtracting the first duration of the first time period from the time at which the usage information is obtained. Also, in some examples, because the tracking component may be powered-off during autoclave processes, the exact times of the autoclave processes may be unknown and may instead be estimated, such based on average durations of autoclave processes that may be measured over time. An estimated autoclave process duration may then be used to estimate times of other autoclave processes preceding the most recent autoclave process. For example, a time of a completion of an autoclave process may be determined by subtracting, from the time at which the usage information is obtained, the estimated autoclave process duration for each intervening autoclave process and the measured time durations that are tracked before each intervening autoclave process and after the most recent autoclave process.

In the example of
As shown in
Next, a time 312 is determined at which the most recent autoclave process is initiated. As described above, in order to preserve and extend battery life, the tracking component is powered-off during autoclave cycles. Thus, the exact duration of the most recent autoclave process cannot be determined based on the usage information obtained from the tracking component. Instead, the duration of the most recent autoclave process may be estimated using an estimated autoclave process duration 320. As described above, in some examples, the estimated autoclave process duration 320 may be determined based on average durations of autoclave processes that may be measured over time. As shown in
Next, as shown in
Next, a time 314 is estimated at which the second-most recent autoclave process is initiated. As shown in
It is noted that, while the above description relates to subtracting various time durations from the time 310 at which usage information is obtained by the external device, it may also be possible to determine and estimate times of autoclave processes by adding tracked time durations to the time 315 of a prior collection of usage information from the tracking component. For example, the time 314 at which the second-most recent autoclave process is initiated may be determined by adding the third duration 303 to the time 315 of the prior collection of usage information from the tracking component. The time 313 at which the second-most recent autoclave process is completed may then be estimated by adding the estimated autoclave process duration 320 to the time 314 at which the second-most recent autoclave process is initiated. The time 312 at which the most recent autoclave process is initiated may then be estimated by adding the second duration 302 to the time 313 at which the second-most recent autoclave process is completed. The time 311 at which the most recent autoclave process is completed may then be estimated by adding the estimated autoclave process duration 320 to the time 313 at which the most recent autoclave process is initiated. It is further noted that, while
