Description

  The present invention relates to a medical pump such as an infusion pump and a syringe pump, and a medical pump system.

  Medical pumps such as infusion pumps and syringe pumps are used to inject various drugs into a patient's body at appropriate doses. Therefore, in a medical pump, it is necessary for a user such as a nurse to set the administration rate of a medicine according to the patient's condition, the kind of the medicine, etc. It has become. On the other hand, it has been proposed to prevent the occurrence of such erroneous settings by using a drug library that sets the upper and lower limits of the flow rate of each drug for each use area of the medical pump. In other words, the drug library is downloaded from a personal computer or the like to the medical pump, and when using the medical pump, the user selects the drug to be administered from the drug library, and the drug administration speed setting error or the doctor's prescription Prevent mistakes (Patent Document 1).

  The drug library is set with operation rules such as the upper and lower limits of the flow rate and the place of use for each drug for the purpose of preventing an erroneous flow rate setting in the pump. About the number of drugs registered, new registrations and updates are made each time, and downloaded to the medical pump for use. Pumps for the upper and lower limits of administration rate, reference administration rate, occlusion pressure setting etc. for each drug Settings can be registered. In addition, for example, drugs can be grouped by creating a profile called ICU and setting a profile for each drug. Accordingly, for example, in a medical pump used in the ICU, selection of such a drug is disabled in the profile for the ICU so that a drug not used in the ICU is not selected, and a doctor, a nurse who is a user, etc. Can prevent mistakes in setting by health care professionals.

[First Embodiment]
Drawing 1 is a figure showing an example of composition of a medical pump system in an embodiment. In FIG. 1, a position detection server 101, a profile server 102, and a plurality of medical pumps 200 are connected by a wireless LAN via a plurality of relays 103. Note that the position detection server 101 or the profile server 102 and the repeater 103 may be connected by wire. The position detection server 101 detects the position of the medical pump 200 based on the communication status between the repeater 103 and the medical pump 200. In addition, the profile server 102 provides a drug library profile (hereinafter simply referred to as a profile) to the medical pump 200 via a wireless LAN.

  FIG. 2 is a block diagram illustrating a configuration of the position detection server 101. Note that the configuration shown in FIG. 2 can be realized in cooperation with appropriate hardware by causing a computer to execute a predetermined program.

  The wireless LAN module 121 is connected to the LAN and enables communication with the repeater 103 and the medical pump 200. The position detection unit 122 determines the position of the medical pump 200 connected to the wireless LAN based on signals from the plurality of repeaters 103. Note that such a position detection technique using a wireless LAN is well known, and detailed description thereof is omitted here. The area determination unit 123 converts the position detected for each of the plurality of medical pumps 200 into area information. The area is a medical facility divided into a plurality of areas, and a ward, a hospital room, or the like can be used as the area. The conversion from the position information to the area information can be realized as follows, for example. That is, an area table 125 is prepared in which each area name of a hospital room or ward is associated with a coordinate value indicating the range of each area, and the area table 125 is referenced to correspond to the position detected by the position detection unit 122. Get the area name.

  The movement detection unit 124 manages the position (area) of one or more medical pumps 200 connected to the wireless LAN using a position management table 301 as shown in FIG. For example, the movement detection unit 124 compares the area determined by the area determination unit 123 with the current area registered in the position management table 301, and determines that the medical pump has moved between the areas if they are different. To do. When the movement detecting unit 124 detects the medical pump that has moved between the areas in this manner, the movement detecting unit 124 notifies the moved medical pump of the moved area. When movement is detected, the current area registered in the area after movement is updated. Note that the configuration for referring to the association table 421 is necessary in the second embodiment, and is omitted in the first embodiment.

  In this embodiment, area management is performed in units of wards and rooms, but the present invention is not limited to this. It suffices if the area is set so that the profile of the medical pump can be switched appropriately. As described above, the position detection server 101 refers to the position management table 301 to transmit position information to each of the medical pumps 200 via the wireless LAN (details will be described later with reference to the flowchart of FIG. 5). ).

  As shown in FIG. 4A, the profile server 102 holds profiles (profile group 401) of a plurality of types of drug libraries for ICU, general ward, and pediatrics. Each profile is related to the setting of the medical pump, and was created for one or more areas in the medical facility to support the setting operation of the medical pump by the user. is there. Then, the profile server 102 downloads the profile to the medical pump 200 via the wireless LAN as necessary. Each profile in the present embodiment includes a profile name 402 and a corresponding area 403 in which an area corresponding to the profile is recorded.

  The repeater 103 is appropriately disposed in various places in the hospital, and connects the medical pump 200 to the wireless LAN. The medical pump 200 is, for example, an infusion pump or a syringe pump, has a built-in wireless function, and is connected to the wireless LAN via the repeater 103.

  FIG. 5 is a block diagram illustrating a configuration example of the medical pump according to the embodiment. Hereinafter, the configuration of the medical pump 200 will be described with reference to FIG. The medical pump 200 has a wireless LAN module 201 for connecting to a wireless LAN via the repeater 103. The control unit 203 includes a CPU, ROM, and RAM (not shown) and performs various controls on the medical pump 200. The user can perform drug setting, flow rate setting, and the like via the operation unit 204. The display unit 205 performs various displays under the control of the control unit 203.

  The liquid feeding mechanism 206 delivers the chemical liquid under the control of the control unit 203. When the medical pump 200 is an infusion pump, the liquid feeding mechanism 206 includes, for example, a plurality of fingers for liquid feeding, and the plurality of fingers sequentially push the liquid transfusing tube to deliver the liquid medicine in the tube. In addition, when the medical pump 200 is a syringe pump, the liquid feeding mechanism 206 is configured to attach a syringe and press the pusher.

  The holding unit 207 holds the area information 208 that is an area notified from the position detection server 101 (FIG. 2) and the profile group 209 downloaded from the profile server 102.

  The operation of the position detection server 101 in the medical pump system of the present embodiment having the above configuration will be described with reference to the flowchart of FIG. The position detection server 101 always knows the positions of the plurality of medical pumps 200 and monitors whether the medical pumps 200 have moved to different areas (different wards, hospital rooms, ICU, NICU, operating rooms, etc.). When the position detection server 101 detects that the medical pump 200 has moved to a different area, the position detection server 101 notifies the medical pump 200 of area information indicating the area.

  First, in step S101, the position detection unit 122 determines whether it is time to detect the position of each medical pump. When it is time to detect the position, the processing after step S102 is started, and the position of the medical pump 200 connected to the wireless LAN is detected. Hereinafter, a pump to be processed among the plurality of medical pumps 200 will be described as a medical pump N. First, in step S102, N is set to 1, and in step S103, the position detection unit 122 performs position detection using a wireless LAN, and based on the signal from the repeater 103, the current position of the medical pump N Is detected. Subsequently, in step S104, the area determination unit 123 refers to the position information (eg, coordinate information) detected in step S103 and refers to the area table 125 to determine an area (eg, information on a ward and a room name).

  Next, in step S105, the movement detection unit 124 compares the current area registered in association with the medical pump N in the position management table 301 with the area determined in step S104. Since the area most recently notified to the medical pump N is registered in the current area of the position management table 301, if the result of this comparison indicates that the two do not match, the medical pump N is moved to another area. Indicates that it has moved. Therefore, the process proceeds from step S106 to step S107, and the movement detection unit 124 notifies the medical pump N of the new area determined in step S104. In step S108, the movement detection unit 124 updates the current area of the medical pump N in the position management table 301 with the determined area. Then, the process proceeds to step S109.

  On the other hand, if the two compared areas match in step S106, the medical pump N has not moved between the areas, and notification of area information and updating of the position management table 301 are not necessary. Therefore, the process skips steps S107 and S108 and proceeds directly to step S109. In step S109, it is determined whether or not the processing has been completed for all the medical pumps connected to the wireless LAN. If not, N is incremented by one in step S110. Then, the process returns to step S103, and the above process is repeated for the next medical pump.

  As described above, the area information in which the medical pump 200 exists is notified from the position detection server 101 to the medical pump 200 connected to the wireless LAN. The medical pump 200 selects an appropriate profile according to this area information, and supports the setting of the chemical solution by the user. Hereinafter, with reference to the flowchart of FIG. 7, the operation | movement in connection with profile selection of the medical pump 200 by this embodiment is demonstrated. It is assumed that the profile group 401 downloaded from the profile server 102 is held as the profile group 209 in the holding unit 207 of the medical pump 200 prior to the processing described below. As shown in FIG. 4A, each profile of the profile group 209 has an area to which the profile can be applied recorded in the corresponding area 403.

  In step S <b> 201, the control unit 203 determines whether an area is notified from the position detection server 101. When the area is notified from the position detection server 101, it indicates that the position detection server 101 has moved to another area. Therefore, the process proceeds to step S202, and the control unit 203 updates the area information 208 with the notified area. Thus, the area information 208 always indicates the latest area notified from the position detection server 101.

  When the setting operation of the user with respect to the medical pump 200 is detected, processing (steps S204 to S207) for automatically selecting an appropriate profile according to the area where the current medical pump 200 exists is executed. First, in step S204, the control unit 203 reads the area information 208 from the holding unit 207, and in step S205, compares it with the area recorded in the corresponding area 403 included in each profile of the profile group 209. In step S <b> 206, the control unit 203 selects a profile that includes an area that matches the area indicated by the area information 208 as the corresponding area 403. In step S207, the control unit 203 executes various setting processes using the selected profile. For example, if the profile group 401 of FIG. 4A is held as the profile group 209 and the area information 208 indicates the ward B, the profile with the profile name “general ward” is selected and used for setting support by the user. Will be.

  As described above, according to the first embodiment, the position detection server always knows the position of the medical pump, and that the pump has moved to different areas (different wards, hospital rooms, operating rooms, ICU, NICU, etc.). When detected, the position (area) is automatically notified to the medical pump. The medical pump holds the notified area and automatically selects an appropriate profile from the information on the held area. Therefore, when a user who is a medical worker such as a doctor or nurse selects a drug with a medical pump or sets the flow rate thereof, the medical pump is appropriate for the current position of the user. A profile can be selected and presented to the user. Therefore, it is possible to reduce the burden on the user by eliminating the operation of profile selection by the user, and to prevent erroneous selection of the profile.

  In the above-described embodiment, the configuration in which the corresponding area is described for each profile as illustrated in FIG. 4A has been described. However, the present invention is not limited to this. For example, as shown in FIG. 4B, it is obvious that the association table 421 that associates the corresponding area with the profile and the profile group 422 may be retained. In this case, each profile of the profile group 422 need not have information on the corresponding area. However, it is necessary to download the association table 421 together with the profile group 422 from the profile server 102 to the medical pump 200.

[Second Embodiment]
In the first embodiment, the area where the medical pump 200 exists is notified to the medical pump 200, and the profile is selected using the area where the medical pump 200 is notified. In the second embodiment, when the position detection server 101 detects movement between areas for the medical pump 200, an appropriate profile is specified according to the area after movement, and identification information for identifying the profile is used as the medical pump. 200 is notified. In the present embodiment, for example, a profile name is used as identification information for identifying a profile. That is, in the first embodiment, the medical pump 200 selects a profile from the area information. In the second embodiment, the position detection server 101 selects a profile from the area information and notifies the medical pump 200 of the profile name. .

  The configuration of the position detection server 101 is as described with reference to FIG. 2, but the position detection server 101 of the second embodiment holds an association table 421 shown in FIG. 4B in addition to the position management table 301. When the movement detection unit 124 detects that the area where the medical pump 200 exists is changed, the movement detection unit 124 acquires the identification information (profile name) of the profile corresponding to the changed area with reference to the association table 421. To do. Thereafter, the movement detection unit 124 transmits the acquired profile name to the medical pump 200. The medical pump 200 selects a profile for the pump setting operation by the user according to the profile name transmitted from the position detection server 101.

  Specific operation procedures of the position detection server 101 and the medical pump 200 will be described with reference to FIGS. The operation of the position detection server 101 of the second embodiment is the same as that of the first embodiment except for step S107. In step S107, the position detection server 101 of the second embodiment refers to the association table 421, acquires the profile name of the profile corresponding to the area determined in step S104, and notifies the medical pump N of this profile name. .

  In the medical pump 200, a profile name is held instead of the area information 208 of the first embodiment. That is, in steps S <b> 201 and S <b> 202 of FIG. 7, the control unit 203 holds the profile name received most recently in the holding unit 207 in response to the notification of the profile name from the position detection server 101. Then, the control unit 203 reads the profile name held in step S202 from the holding unit 207 (step S204) and compares it with each profile name in the profile group 209 (step S205). Then, the control unit 203 selects a profile that matches the profile name held in the holding unit 207 from the profile group 209 held in the holding unit 207 (step S206). The processing of other steps is as described in the first embodiment.

[Third Embodiment]
In the first and second embodiments, the medical pump 200 holds the profile group 209 and should be used according to the area (first embodiment) or profile name (second embodiment) notified from the position detection server 101. Configured to select a profile. In the third embodiment, the medical pump 200 always holds only the profile corresponding to the area, thereby preventing erroneous selection of the profile by the user.

  FIG. 8 is a flowchart for explaining the operation of the position detection server 101 according to the third embodiment. In FIG. 8, the same processing steps as those in FIG. 6 are given the same numbers as in FIG. In FIG. 8, step S107 in FIG. 6 is replaced with steps S121 and S122. In step S <b> 121, the movement detection unit 124 selects the profile name of the profile corresponding to the current area determined by the area determination unit 123 by referring to the association table 421. In step S122, the movement detection unit 124 instructs the profile server 102 to download the profile selected in step S121 to the medical pump N via the wireless LAN module 121.

  When the profile server 102 receives the profile name of the profile to be downloaded and the instruction of the medical pump (medical pump N) to be downloaded from the position detection server 101, the profile server 102 downloads the designated profile to the medical pump N. In the above process, the position detection server 101 specifies a profile name and sends an instruction to the profile server 102, but the present invention is not limited to this. For example, the detected area may be notified from the position detection server 101, and the profile to be downloaded may be selected from the notified area.

  The medical pump 200 of the third embodiment has the same configuration as that of the first embodiment (FIG. 5), but a single profile is stored in the holding unit 207, and the area information 208 is not held. FIG. 9 is a flowchart for explaining the operation of the medical pump 200 according to the third embodiment. In step S <b> 221, the control unit 203 determines whether a new profile has been downloaded from the profile server 102. When a new profile is downloaded, in step S222, the control unit 203 holds the downloaded profile in the holding unit 207 and discards the profile held so far. Thus, the profile in the holding unit 207 is updated with the newly downloaded profile, and the holding unit 207 holds the latest profile.

  In step S223, when a setting operation by the user is accepted, the process proceeds to step S224. In step S224, the control unit 203 performs setting processing using the profile currently held in the holding unit 207.

  As described above, according to the third embodiment, since only the profile corresponding to the area is held and used in the medical pump 200, the erroneous selection of the profile due to the movement of the medical pump 200 is prevented. Is done. Further, only the appropriate profile corresponding to the area is held in the medical pump 200, and the memory capacity can be saved as compared with the case where a plurality of profiles are held.

  In each of the above embodiments, the position detection server 101 and the profile server 102 have been described as separate information processing apparatuses. However, these may be realized by an integrated information processing apparatus.

Further, in each of the above embodiments, the medical pump 200 stores the identification information (profile name) of the last used profile, and when the profile is selected for the setting operation, it is selected between the previous time and the current time. It may be determined whether the profile matches, and if it does not match, this may be notified.
