  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. 1-5 is a figure which shows one Embodiment of the location management system of the portable apparatus which concerns on this invention.

  In FIG. 1, the portable device location management system 10 has a plurality of types of movable devices M, for example, a syringe pump M1, an echo examination device M2, an anesthesia device M3, an electric scalpel device M4, and an operating table M5. Are installed in hospital facilities that use a plurality of ME (medical engineering) devices M such as ward W (see FIG. 2). The location management system 10 includes a transmission tag (transmitting unit) 11 that is installed in the ME device M and constantly transmits a specific radio wave rw, and a receiving antenna (reception unit) that receives the specific radio wave rw that is always transmitted by the transmission tag 11. 12, a receiver 13 that extracts various information from the specific radio wave rw received by the receiving antenna 12, and receives information received from the receiver 13 to inquire about the location of the ME device M from an external PC (personal computer) 100. It is constructed from a management server (management unit) 14 for registering and managing related information in databases 27a to 27c, which will be described later (inquiry / notification). The management server 14 is always connected individually to the receiver 13 via a wired or wireless connection network 16, while the external PC 100 can be arbitrarily requested by a user via a LAN (Local Area Network) 17. Connected accordingly. The external PC 100 is a general-purpose PC used in an ME management room (not shown) in which a clinical engineer who manages the ME device M resides, and performs various information input operations in the same manner as the management server 14 described later. An operation unit 24 and a display unit 25 for displaying and outputting various information are provided (the operation unit 24 and the display unit 25 of the external PC 100 are not shown).

  The outgoing tag 11 is an active tag type RFID (radio frequency identification) tag that constantly emits a weak radio wave rw using a built-in battery as a power source. The outgoing tag 11 is capable of emitting a specific radio wave rw without being disturbed. It is installed in the device M. In addition, the outgoing tag 11 is preset with at least its own identification information, and always transmits a specific radio wave rw having a specific frequency including the identification information. This outgoing tag 11 connects between the examination room S, treatment room T, and hospital room R that use the ME device M, and is within the movement width of the corridor P that becomes the movement route in the ward W of the ME device M. The specific radio wave rw is set to be transmitted at a radio wave intensity that can be received by the receiver 13 via the receiving antenna 12. The transmission tag 11 may be set so that the identification information of the ME device M to be installed can be transmitted on the specific radio wave rw. In this embodiment, the identification information for each transmission tag 11 (default may be used). It is preferable that the ME device M to be installed is changed as it is and installed so that it can be used.

  The receiving antennas 12 are installed at a plurality of locations (reception points) of the corridor P in the ward W, and the receiver 13 receives the specific radio wave rw transmitted from the transmitting tag 11 of the ME device M moving in the corridor P. The information is received via the antenna 12 and at least the identification information is acquired and transferred to the management server 14. Here, it goes without saying that the receiving antenna 12 may be installed other than the corridor P. For example, the receiving antenna 12 can also be installed on a stairway that connects each floor of the ward W to manage the location of the ME device M more accurately. However, as will be described later, since the location of the ME device M can be effectively estimated, it is necessary to install the area A where the specific radio wave rw from the transmission tag 11 can be received. It is sufficient if it is installed at a key point such as a branch point of the corridor P of the receiving antenna 12.

  The management server 14 uses a RAM (random-access memory) 23 as a work area according to a management program and various parameters stored in a ROM (read-only memory) 22 by a central processing unit (CPU) 21 in advance. By performing arithmetic operations, each part of the apparatus is controlled in an integrated manner. The management server 14 includes an operation unit 24 for inputting various requests and information, and a display unit 25 for monitoring and displaying input information from the operation unit 24 and processing information by the CPU 21 together with the CPU 21, ROM 22, and RAM 23. 29 is connected.

  The management server 14 has a connection network 16 IF (Interface) 26a and a LAN 17 IF 26b connected to the bus 29 so that the CPU 21 can exchange information with the receiver 13 (receiving antenna 12) and the external PC 100. In addition, the management server 14 is connected to the bus 29 by an HDD (hard disk drive) 27 that stores various information read / written by the CPU 21 in a nonvolatile manner.

  In the HDD 27 of the management server 14, a floor DB (database) 27a, a device DB 27b, and a patient DB 27c are prepared for storage in advance so that the CPU 21 can read and write. In the floor DB 27a, as shown in FIG. 2, the installation location of the receiving antenna 12 is provided together with the corridor P, the examination room S, the treatment room T, the hospital room R, etc. of each floor of the ward W that is the destination (destination) of the ME device M. The floor guide map G including it is stored. As shown in FIG. 3, the device DB (registration unit) 27b is associated with the identification information (tag No.) of the transmission tag 11, and is associated with a syringe pump, an echo test device, an anesthesia device, an electric scalpel device, an operating table. Type identification information M1 to M5 for each ME device M, etc., and identification information (table No.), name, and specification of each ME device M, usage frequency% in the examination room S, treatment room T, hospital room R (movable) Information) and various types of information such as doctors using the ME device M are registered. In the patient DB (acquisition unit) 27c, as shown in FIG. 4, various information related to treatment such as a patient (device user) who needs to use the ME device M and a doctor in charge of the patient is stored in the ward W. Acquired and registered in conjunction with the reception.

  The CPU 21 of the management server 14 executes the above-described management program and performs a preparation process for managing the location of the ME device M. Specifically, the CPU 21 receives the specific radio wave rw transmitted from the transmission tag 11 of the ME device M by the receiver 13 through the reception antenna 12 at a predetermined interval, for example, an arbitrary setting interval of 1 to 30 seconds. It is supposed to let you. The CPU 21 retrieves the identification information of the outgoing tag 11 included in the received specific radio wave rw, and searches for the associated ME device M in the device DB 27b shown in FIG. The ME device M is associated with the reception time t and the installation location g in the floor guide map G of the reception antenna 12, and at least the latest reception time g1 at the latest previous time t1 and the previous time t2 in the device DB 27b, The process of updating the registration information of g2 to gn is repeated.

  Further, the CPU 21 performs parallel processing of another preparation process useful for location management of the ME device M during execution of the above management program. Specifically, for example, the CPU 21 receives identification information input when the patient visits the ward W and when the patient leaves the ward W. When receiving the patient identification information, the CPU 21b shown in FIG. In addition, a corresponding patient associated with each other is searched, and an update process for registering / deleting a flag indicating that the corresponding patient is during the consultation period and after the completion of the examination is executed.

  Thereafter, during execution of the management program, the CPU 21 receives, for example, a clinical engineer (system user) who has received a loan request for the ME device M from a doctor who needs to use a certain type of ME device M. When the request input for inquiring about the location is received from the operation unit 24 of the server 14 or from the operation unit 24 of the external PC 100 via the LAN 26b together with the designation of the examination room S of the use location, A management process for searching for and reporting the location is executed.

  Specifically, as shown in the flowchart of FIG. 5, when there is an inquiry about the location of the ME device M (step S11), a list of ME devices M registered in the device DB 27b is searched for, for example, the searched ME. The type of device M is displayed and output on the display unit 25 so that it can be specified (step S12). When there is an input for selecting the required type of ME device M from the list (step S13), all the selected types of ME devices M are searched from the device DB 27b (step S14), and the patient DB 27c is searched. After confirming the presence or absence of elements to be considered, such as the last use of the ME device M by the attending physician of the patient who has arrived at the ward W (step S15), the corresponding previous time t1 and the latest time t2 are associated with each of them. The reception location information g1 and g2 are read (step S16).

  Thereafter, the movement path and the movement direction of the ME device M are specified based on the time series corresponding to the previous time t1 and the previous time t2, which are the reception timings in the reception location information g1 and g2 of the searched ME device M. The candidate is placed in the order closest to the designated examination room S, assuming that it is located in any of the examination room S, treatment room T, or hospital room R adjacent to the receiving antenna 12 received immediately before (step S17). At this time, in step S15, for example, if it matches the type of ME device M used by the doctor in charge of the patient registered in the patient DB 27c as being in the consultation period, the doctor is located in the examination room S where the doctor is located. The ME devices M that are estimated with high possibility are corrected in the order of the lower candidates (step S18). After the location candidate is estimated, the unit number (identification number) and specifications of the ME device M are displayed and output on the display unit 25 of the management server 14 or the external PC 100 that has input the location of the ME device M (step). S19).

  When the clinical engineer who sees this selects the ME device M from the candidates in consideration of the selection elements such as the nearest location from the clinic S or the like used by the doctor who has requested the loan (step S21), the patient DB 27c After confirming the presence or absence of factors to be considered, such as use immediately before the attending doctor who examines the patient, such as matching with the ME device M of the type used by the attending doctor who is registered as having completed the consultation (step S22) ) Management for inputting the inquiry request with the location (movability) of the estimated location of the selected ME device M according to the frequency of use in the examination room S, the treatment room T, and the hospital room R. An image is displayed in the floor guide map G that is displayed and output on the display unit 25 of the server 14 or the external PC 100 (step S23). That is, the display unit 25 constitutes a notification unit. In addition, as a selection element to be taken into consideration, a machine number that is designated by the doctor who requested the loan and is suitable for the patient, or a specification that the patient is used to, etc. can be cited.

  Specifically, in the floor guide map G, the possibility of the location of the ME device M is indicated by numbers and colors. For example, as shown in FIG. Numbers and red (indicated by hatching tone in the figure), 30% location possibility is indicated in the treatment room T by numbers and yellow, and 15% location possibility is indicated in the room R by numbers and blue. In other places where there is a possibility of movement, the location possibility 4% of the ME device M is indicated by a number and light blue (not shown). In addition, for example, there is no possibility of being located normally like warehouse X or toilet B, but the possibility of being located is 1% indicating that there is little possibility that it is located because the movement route and the movement direction match. And shown in gray.

  As a result, a clinical engineer who searches for an ME device M can search for the ME device M early and without burden by referring to the% number and display color of the possibility of being located in the nearby floor guide map G. be able to. In addition, for example, it is possible to avoid wasteful travel by lowering the candidate order of ME devices M that are likely to be used by a doctor who examines a patient.

  At this time, in step S23, for example, if it is registered in the patient DB 27c that a patient who has received a medical examination using the ME device M has just been completed, a medical examination in which the patient's doctor is in charge. The possibility of the location of the corresponding ME device M in the room S is corrected to be displayed in the floor guide map G.

  Thereby, the clinical engineer who searches for the ME device M can preferentially find the ME device M that is likely to be located and has been used, and can find the ME device M earlier and without burden. .

  Therefore, it is possible to eliminate the necessity of crushing the unreceivable area by installing countless reception antennas 12 in the ward W so that the specific radio wave rw from the transmission tag 11 is passed between the reception antennas 12. The location of the ME device M can be estimated and used efficiently.

  As described above, in the present embodiment, the location of the ME device M can be obtained by installing the transmission tag 11 in the ME device M and installing the reception antenna 12 only at the specific points g1 to gn without worrying about reception leakage. The location can be estimated and managed, the location management system 10 of the ME device M is constructed at low cost, and useful information that informs a clinical engineer who searches for the ME device M of the possibility of the location is provided. be able to.

  Here, in this embodiment, the case where it is installed in a hospital facility will be described as an example. However, the present invention is not limited to this, and can also be suitably used in a university facility or a research facility.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea.
