-
FIG. 1 is a diagram illustrating a functional configuration of a vital signinformation processing system 1 according to an embodiment of the presently disclosed subject matter. The vital signinformation processing system 1 includes asensor 2 and aninformation acquisition apparatus 3. Thesensor 2 is configured to be attached to a patient 4 (an example of the living body). Theinformation acquisition apparatus 3 is configured to acquire vital sign information of thepatient 4 through thesensor 2. That is, thesensor 2 is configured to communicate with theinformation acquisition apparatus 3. - Examples of the
sensor 2 include an SpO2 probe for acquiring the arterial oxygen saturation of thepatient 4 as vital sign information, electrocardiogram electrodes for acquiring an electrocardiogram of thepatient 4 as vital sign information, brain wave electrodes for acquiring the brain wave of thepatient 4 as vital sign information, a cuff for acquiring the non-invasive blood pressure of thepatient 4 as vital sign information, and the like. Examples of theinformation acquisition apparatus 3 include a bedside monitor and the like. - The
sensor 2 includes afirst memory 21. Thefirst memory 21 may include a semiconductor memory and the like. Thefirst memory 21 storesfirst site information 211 indicative of one or more sites where thesensor 2 is to be used. Examples of the one or more sites include a critical care medicine area, an intensive care unit, a neonatal intensive care unit, an operating room, a laboratory, a hospital ward, and an MRI room. - The
first site information 211 may be written by a user via an information writing apparatus before using thesensor 2. Theinformation acquisition apparatus 3 may be configured to function as the information writing apparatus. In a case where thesensor 2 is designed for specific use (e.g., a sensor which can be used only in an operating room), the first site information may be previously written during manufacturing. - The
information acquisition apparatus 3 includes aprocessor 31 and asecond memory 32. Examples of theprocessor 31 include a CPU and an MPU. Thesecond memory 32 may include a semiconductor memory, a hard disk drive, or the like. Thesecond memory 32 storessecond site information 321 indicative of one or more sites where theinformation acquisition apparatus 3 is to be used. - The
second site information 321 may be written by a user via an information writing apparatus before installing theinformation acquisition apparatus 3. In a case where the information acquisition apparatus is designed for specific use (e.g., an apparatus which can be used only in an operating room), the second site information may be previously written during manufacturing. -
FIG. 2 illustrates a process to be performed by theinformation acquisition apparatus 3 under control of theprocessor 31. The process is performed when theprocessor 31 executes instructions stored in a memory (a ROM, a RAM, or the like). - First, the
processor 31 causes theinformation acquisition apparatus 3 to determine whether a condition that enables communication with thesensor 2 is met (step S1). If the communicable condition is not met (N in step S1), theinformation acquisition apparatus 3 is caused to repeat the determination until this condition is met. - If the condition that enables the communication with the
sensor 2 is met (Y in step S1), theprocessor 31 causes theinformation acquisition apparatus 3 to acquire the first site information 211 (step S2). Theinformation acquisition apparatus 3 acquires thefirst site information 211 from thefirst memory 21 of thesensor 2. - Next, the
processor 31 causes theinformation acquisition apparatus 3 to compare thefirst site information 211 and thesecond site information 321 with each other (step S3). Theinformation acquisition apparatus 3 compares thefirst site information 211 acquired from thesensor 2, with thesecond site information 321 stored in thesecond memory 32. - If, as a result of the comparison, it is determined that the
first site information 211 and thesecond site information 321 are matched (Y in step S3), theprocessor 31 causes theinformation acquisition apparatus 3 to acquire vital sign information of the patient 4 (step S4). Theinformation acquisition apparatus 3 acquires vital sign information of thepatient 4 through thesensor 2. - If, as a result of the comparison, it is determined that the
first site information 211 and thesecond site information 321 are not matched (N in step S3), theprocessor 31 causes theinformation acquisition apparatus 3 to perform a notification process (step S5). For Or example the site indicated by thefirst site information 211 is a neonatal care unit, and that indicated by thesecond site information 321 is a hospital ward, for example, theinformation acquisition apparatus 3 performs notification. - The comparison result that the
first site information 211 and thesecond site information 321 are matched indicates a fact that thesensor 2 is used at a proper site. In contrast, the comparison result that thefirst site information 211 and thesecond site information 321 are not matched indicates a fact that thesensor 2 not originally existed at the site is, for some reason, in communication with theinformation acquisition apparatus 3. For example, it is possible that thesensor 2 that was used with another patient at another site has been moved together with this patient to the site at which theinformation acquisition apparatus 3 is installed. - The notification process may cause a user to recognize this fact, and urge the user to replace the
sensor 2. The notification may be at least one of visual notification, audible notification, and haptic notification. Examples of the notification process include a generation of an alarm sound, a lighting of an indicator, a display of a message, a generation of vibration, and the like. This can prevent thesensor 2 from being erroneously used. - The notification performed by the
information acquisition apparatus 3 may include thefirst site information 211. For example, if thefirst site information 211 indicates a neonatal care unit, and thesecond site information 321 indicates a hospital ward, theinformation acquisition apparatus 3 may produce the notification that includes information indicating that thesensor 2 being used should originally be used in a neonatal care unit. - According to this configuration, it is possible to prompt a user to return the
sensor 2 that should not be used at a site where theinformation acquisition apparatus 3 is installed, to the original site. This can prevent thesensor 2 from being erroneously used, and also correct an unintended variation in the stock of sensors at each site. - When the notification process is performed, as indicated by the broken line in
FIG. 2 , theprocessor 31 may control theinformation acquisition apparatus 3 to perform a restriction process (step S6). In the restriction process, the use of thesensor 2 communicating with theinformation acquisition apparatus 3 is restricted. Examples of the restriction process include an immediate prohibition of the use of thesensor 2, a setting of limitation of the number of usable times of thesensor 2, a continuous output of a notification message, and the like. - According to this configuration, it is possible to suppress a situation where a user continues to use the
sensor 2 that should not exist at the site where the currently-communicatinginformation acquisition apparatus 3 is installed. Therefore, the effect of prevention of erroneous use of thesensor 2 is enhanced. - The
first site information 211 stored in thefirst memory 21 of thesensor 2 may include a plurality of sites where thesensor 2 can be used. - According to this configuration, the
sensor 2 is allowed to be shared among the plurality of sites. For example, at sites among which a patient is moved relatively frequently, such as an operating room and an intensive care unit, an operation in which the same sensor is allowed to be used at both sites is more efficient. This enables a flexible operation while preventing thesensor 2 from being erroneously used. - As indicated by the broken line in
FIG. 2 , theprocessor 31 may control theinformation acquisition apparatus 3 to record information of usage history (step S7). As indicated by the broken lines inFIG. 1 , theinformation acquisition apparatus 3 may record thesecond site information 321 indicative of the site at which it is installed, in thefirst memory 21 of thesensor 2 asusage history information 212. Theusage history information 212 is readable by theinformation acquisition apparatus 3 or an information processing device. - The
usage history information 212 is particularly effective in a case where the sensor is used while being moved among a plurality of sites (i.e., in a case where thefirst site information 211 includes a plurality of sites). By allowing a user to check, at the end of operation, the usage history information, the user can easily return the sensor to the site to which the sensor should belong. Therefore, it is possible to suppress an unintended variation in the stock of sensors at each site. - The recording of the
usage history information 212 by theinformation acquisition apparatus 3 can be performed at any timing after the communication with thesensor 2 is enabled. It is however preferable that, as shown inFIG. 2 , the recording be performed after vital sign information is acquired. - By doing so, it is possible to prevent a situation where, when a user erroneously attaches a sensor to the
information acquisition apparatus 3 instead of a sensor that should originally be used, unintendedusage history information 212 is recorded. If it is recorded after the acquisition of vital sign information, there is a high likelihood that the sensor used for the acquisition is intentionally connected to theinformation acquisition apparatus 3. In order to achieve a same or similar effect, theusage history information 212 may be recorded when a period of time of communication between thesensor 2 and theinformation acquisition apparatus 3 reaches a threshold. - If, as a result of the comparison process (step S3) performed by the
information acquisition apparatus 3, thefirst site information 211 and thesecond site information 321 are not matched, and theusage history information 212 is recorded in thefirst memory 21 of thesensor 2, the notification by theinformation acquisition apparatus 3 may include theusage history information 212. Theusage history information 212 may be displayed by theinformation acquisition apparatus 3, or output in the form of a printed report or the like. - The notification of the
usage history information 212 is particularly effective in a case where the sensor is used while being moved among a plurality of sites (i.e., in a case where thefirst site information 211 includes a plurality of sites). By checking the notifiedusage history information 212, the user can not only become aware of the site to which the sensor is to be returned, and but also use this information in investigating a cause of an erroneous movement. - In a case where a sequence of sites indicated by the
usage history information 212 as the sites at which thesensor 2 have been used matches a predetermined sequence, theprocessor 31 may cause theinformation acquisition apparatus 3 to perform the notification. The predetermined sequence may be a sequence which never happens in a usual medical procedure flow, or a sequence which must not exist. An example of such a sequence is a sequence in which an intensive care unit is followed by a critical care medicine area. - This configuration is particularly effective in a case where the sensor is used while being moved among a plurality of sites (i.e., in a case where the
first site information 211 includes a plurality of sites). A movement of the sensor among the sites at which the sensor is allowed to be used but in a sequence that should not occur can be notified. - For example, in a case where the
sensor 2 in which a critical care medicine area and an intensive care unit are stored as thefirst site information 211 is moved from the intensive care unit to the critical care medicine area, notification will not be performed only by a comparison with thesecond site information 321. When theusage history information 212 indicates the movement from the intensive care unit to the critical care medicine area, however, this impermissible movement of thesensor 2 can be identified. - As indicated by the broken line in
FIG. 1 , theinformation acquisition apparatus 3 can be communicably connected to anexternal management apparatus 5. With this configuration, as indicated by the broken line inFIG. 2 , theprocessor 31 can control theinformation acquisition apparatus 3 to perform the notification process (step S8). Theinformation acquisition apparatus 3 notifies themanagement apparatus 5 of theusage history information 212 that has been read from thefirst memory 21 of thesensor 2. - According to this configuration, a set of usage history information notified from the
information acquisition apparatuses 3 installed in respective sites can be centrally managed by themanagement apparatus 5. This makes it easy to manage the stock of sensors a each site, and to monitor the actual use of the sensors. - As indicated by the broken line in
FIG. 1 ,condition information 213 may be stored in thefirst memory 21 of thesensor 2. Thecondition information 213 includes information indicative of operating conditions of theinformation acquisition apparatus 3. Examples of thecondition information 213 include background information of the patient 4 (e.g., age, disease, risk factors, applied treatments, and the like), and information of characteristics of the sensor 2 (a product number, use conditions, the number of uses, and the like). - If, as a result of the comparison process (step S3) performed by the
information acquisition apparatus 3, thefirst site information 211 and thesecond site information 321 are matched, theprocessor 31 controls theinformation acquisition apparatus 3 to read thecondition information 213 in the first memory 21 (step S9). Theprocessor 31 controls theinformation acquisition apparatus 3 to acquire vital sign information based on setting according to thecondition information 213. In theinformation acquisition apparatus 3, for example, measurement conditions according to the background information of thepatient 4 and the characteristic information of thesensor 2 may be set automatically. - According to this configuration, even in a case where the
sensor 2 is moved among a plurality of sites, and connected to differentinformation acquisition apparatuses 3, identical information acquisition conditions can be easily set. This reduces a burden on a medical person relating to the setting, and improves the accuracy of acquisition of vital sign information. -
FIG. 3 illustrates an example of the configuration of thesensor 2. Thesensor 2 may include anattachment portion 22, aconnector 23, and acable 24. Theattachment portion 22 is configured to be attached to the body of thepatient 4, and includes a sensor device. Theconnector 23 is configured to allow the sensor to communicate with theinformation acquisition apparatus 3. Theconnector 23 may be directly connected to theinformation acquisition apparatus 3, or indirectly connected through a junction cable or the like. Thecable 24 connects theattachment portion 22 to theconnector 23. Thecable 24 incudes a power supply line and signal lines necessary for acquisition of vital sign information. - In this example, the
first memory 21 is preferably disposed in theconnector 23 which is necessary for enabling communication with theinformation acquisition apparatus 3, so that the size of theattachment portion 22 to be attached to the body of thepatient 4 can be prevented from being increased. That is, while providing thefirst memory 21 storing information for preventing thesensor 2 from being erroneously used, it is possible to prevent thepatient 4 from feeling bothersomeness. - While the presently disclosed subject matter has been described with reference to a certain embodiment thereof, it will be understood by a person skilled in the art that various changes and modifications can be made therein.
