Title: Information processing method and system using medical examination device as medium

Description:
[0001] This application claims a benefit of foreign priority based on Japanese Patent Application No. 2002267327, filed on Sep. 12, 2002, which is hereby incorporated by reference herein in its entirety as if fully set forth herein.  
       BACKGROUND OF THE INVENTION  
       [0002] The present invention relates generally to information processing method and system using a medical examination device (MED) as a medium, and more particularly to those in a medical system that uses a MED, such as a DNA chip, a lab on a chip, a micro-array, a micro-TAS, a device for inspection using a quarts crystal microbalance (QCM) reaction, etc. for medical examinations, diagnoses, etc.  
       [0003] Recent medical examinations, diagnoses, etc. have actively developed a medical system that uses a MED referred to as a QCM DNA chip, a lab on a chip, a micro-array, a micro-TAS, etc.  
       [0004] However, widespread MEDs have raised a issue of managements of the MEDs and information obtained from the MEDs. For example, it is known that the MED has a short product life cycle, and requires careful control. In addition, usages are different according to MED types, and a misuse results in a different result, causing an improper diagnosis. The misdiagnosis is a great problem in a medical inspection result.  
       [0005] It is conceivable that mailing is used to inform a result obtained from a chip, but this procedure is arduously repeated by the number of institutions when plural institutions need the result. It is quite important to securely process information of an MED that may identify personal information.  
       [0006] There may be recited following considerations between institutions handling MEDs and individual users:  
       [0007] (1) MED vendors (who manufacture and ship MEDs) need control MEDs&#39; product life cycles, circulations and purchasers.  
       [0008] (2) Distributors (who circulate and sell MEDs) need confirm shipping dates of MEDs.  
       [0009] (3) Medical institutions and drugstores (which supply and sell MEDs) need to use MEDs within their lifetimes, to confirm their contents, to recognize their usages and inform them to individual users, and to recognize inspection results of MEDs.  
       [0010] (4) Individual users or patients need to recognize usages and inspection results of MEDs.  
       [0011] (5) Inspection institutions (which inspect MEDs and supply inspection results) need to recognize usage records of MEDs, and to easily inform inspection results of MEDs.  
       [0012] (6) MED vendors (who recycle MEDs) need to recognize usage records of MEDs, and easily inform recycles of MEDs.  
       [0013] As apparent from the above, institutions handling MEDs and individual users have common and specific considerations regarding managements of MEDs themselves and information obtained from the MEDs. However, no approaches have not yet been developed for sharing and effectively utilizing information obtained from MEDs among institutions handling MEDs and individual users.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS  
     [0035] Preferred embodiments of the present invention will now be described in detail in accordance with the accompanying drawings.  
     [0036] When the above information processing method and system are applied, for example, an information processing method utilizes a MED such as a DNA chip, which has been assigned a unique identification used for medical examinations, diagnoses, etc. a memory in a server, etc. into which particular additional information about the medical examination device is remotely writable and readable through a network, such as the Internet, based on the identification of the medical examination device, and plural input/output units (such as PCs provided in an MED supplier, seller and inspection institution) for remotely writing particular additional information relating to a usage of the MED into and reading the information from the memory through the network. Thereby, the particular additional information may be shared and utilized among a plurality of users based on the identification.  
     [0037] This enables, for example, the MED vendor to manage a lifetime of the MED, as well as realizing real-time managements of the usage of the MED in a process of circulation and at a purchaser. The medical institution and drugstore may process an MED within its lifetime, and easily recognize the contents and usage of the MED and inform a user of the information.  
     [0038] Moreover, an individual user may easily recognize the usage of the MED. The inspection institution recognizes a use record of a MED, providing more accurate inspection and detection, and easily informing an inspection result of the MED. The medical institution and individual user may promptly and accurately recognize an inspection result by the inspection institution.  
     [0039] According to the above information processing method and system, sharing and utilizing of particular additional information among plural users based on the identification would effectively utilize the particular additional information of the MEDs. For example, the medical institution may recognize how the MED has been used. Here, it is conceivable to commit a disposal of any used MED to a medical waste disposal company without delivering the MED to the MED vendor for recycling. In this case, the company, etc. to whom the inspection institution has committed a disposal may register the disposal information relying upon the ID assigned to the MED. It is possible to inform medical institutions and independent users that MEDs, from which personal information of the independent users may be disclosed, have securely processed, for example, by uploading information of collected and disposed MEDs on a server on the network.  
     [0040] A description will now be given of embodiments according to the present invention.  
     [0041] First Embodiment  
     [0042]FIG. 1 is a view of a first embodiment according to the present invention showing one mode of share and utilization of an MED among plural users, which has been shipped by an MED vendor. FIG. 2 is a flowchart of a utilization mode of the MED in the first embodiment shown in FIG. 1. Here, a term “MED” generalizes such instruments as a DNA chip, Lab on a Chip, a micro-array, and a micro-TAS, which are used for medical diagnoses.  
     [0043] A description will now be given of a first embodiment according to the present invention using flowcharts shown in FIGS. 1 and 2, and a system explanatory view in FIG. 6. A description will now be given of a system with reference to FIG. 6.  
     [0044] The MED vendor  11  that makes MEDs  10  serves to built a system and manage a server  12  as storage means in this system as well as having an MED information input unit, such as a personal computer (“PC”) connected to the server  12 .  
     [0045] The distributor  12  who sells the MEDs  10  may input information through the Internet via the server  12  and a LAN, and has an MED information input unit  16   a , such as a PC.  
     [0046] A medical institution  13 , such as a hospital, may input and output information through the Internet via the server  12  and a LAN, and includes an MED information input unit  13   a  and an MED information display  13   b , such as a PC.  
     [0047] An inspection center  14  which inspects the MEDs  10  may input and output information through the Internet via the server  12  and a LAN, and includes an MED information input unit  14   a  and an MED information display  14   b , such as a PC. In addition, the inspection center  14  includes a MED result reader  14   c  and MED inspection unit  14   d  for inspecting the MEDs  10 .  
     [0048] A patient or individual user  15  may input information through the Internet via the server  12  and the LAN, and possesses a medical inspection information display  15   b , such as a PC.  
     [0049] A description will be given of a system flow.  
     [0050] The MED vendor  11  makes the MED  10  (step S 201 ), and assigns an ID to the MED  10  (step S 202 ). Here, a medical device, such as a DNA chip shown in FIG. 5, is made as the MED  10 , and assigned a symbol that represents an ID as shown in FIG. 5A, or a barcode as shown in FIG. 5B.  
     [0051] The MED vendor  11  registers the ID assigned to the MED  10  in the server  12  (step S 203 ) as well as its usage and usable term or lifetime unique to this MED (step S 203 ). In the DNA chips, etc., actual usage for a patient changes according to novel developments, and a registration of the usage is extremely important information for future inspection purposes.  
     [0052] After this registration, the MED vendor  11  ships the MED  10  (step S 204 ).  
     [0053] The distributor  16  that handles circulations and distributions of the MEDs  10  stores the MEDs  10  for sale. The MED vendor  11  may serve as the distributor  16 . The distributor  16  registers information on a process of circulation, such as temperature control, room temperature exposure time, and couriers and dates, with IDs as keys in the server  12  (step  205 ). The distributor  16  sells the MEDs  10  (step S 206 ), and registers information of purchasers and sales dates with IDs as keys in the server  12 .  
     [0054] The medical institution  13 , such as a hospital and a clinic, uses purchased MEDs  10  (step S 208 ), while using an ID as a key to view reference information necessary for the MED  10  as MED-related information which the MED vendor  11  has already registered, such as usage and expiration date of the MED  10  (step S 209 ), thereby reducing misapplications with the utmost care. The medical institution  13  registers a use status and a user or patient name in the server (step S 210 ), and informs the user or patient  15  of the ID of the MED  10  (step S 211 ).  
     [0055] The medical institution  13 , etc. that has used the MED  10  disposes the MEDs  10  by itself, or delivers the MEDs  10  to an inspection center, such as a specialized evaluation institution that undertakes depositary inspections of MEDs  10  (step S 212 ). The inspection center or institution  14  that receives the delivery uses an ID as a key to register a delivery statue and condition, such as a shipping state, temperature control state, a time period and the number of days required, and a reception date in the server  12  (step S 213 ).  
     [0056] The inspection center  14  inspects the MED  10  (step S 214 ), and registers the inspection information in the server  12  (step S 215 A). The inspection center  14  disposes the useless MED  10  (step S 216 ), and registers the disposal state, method, date and time, etc., in the server  12  (step S 217 ).  
     [0057] Alternatively, the inspection center  14  delivers the MEDs  10  to the MED vendor  11  for recycling without disposal. The MED vendor  11  determines whether the MED  10  is to be recycled, by taking into consideration its lifetime (such as the number of usable times, and the number of elapsed days from the manufacture date) of the MED  10 , and management information (such as temperature control and delivery state) in a process of circulation at the medical institution and inspection center, etc. The record information was read out from the server  12  using an ID as a key. Of course, a new ID is assigned in recycling. However, a correlation with a prior ID is registered in the server  12  so that all the records after manufacture may be tracked in determining recycling again.  
     [0058] The medical institution  13  (such as a doctor) may use an ID as a key to view an inspection result of the MED  10  registered by the inspection center  14  (step S 215 B). The patient  15  is restricted to access the server  12  so that he may access the MED  10  that was used for his own examination and view its inspection result. He cannot view information inappropriate to be informed to him, such as information other than his medical information, even if the MED  10  was used for his examination.  
     [0059] The above embodiment uses a system etc. that uses a network, e.g., LAN, using the Internet shown in FIG. 6 to enable the MED vendor  11 , the distributor  16 , the inspection center  14 , etc. to write such information about the MEDs  10  as an ID, usage, lifetime, information on a process of circulation, and inspection information, down in the storage means in the server  2 . Thereby, it uses an ID of the MED  10  as a key to remotely write particular additional information in the server  12  through input means provided in these MED vendor  11 , distributor  16 , inspection center  14 , etc. via the network.  
     [0060] In this way, a manufacturer of the MEDs and a plurality of users, such as a computer of the MED vendor  11 , a computer of a doctor or medical institution  13  as a user, a computer of the individual  15 , and a computer of the inspection center  14 , register their statuses in the server  12  on the network, enabling a unitary management of all the information relating to the MED  10  using a chip ID. When the MED vendor  11  builds this system, it restricts accesses to viewable information based on a status of each client, checks any unfilled necessary information, and manages stored or registered record information, such as a date and a writer.  
     [0061] This system enables an ID of one MED to be commonly used for a plurality of cites, and a plurality of users to use the ID as a key to register, view and utilize information of the MED  10 . Thereby, the MED vender  11  may manage an expiration date and use status of each shipped MED  10 , enlighten appropriate use, and recognize whether it is properly used. The distributor  16  or a MED seller may readily recognize a shipping status from the MED vendor  11 . Each user may recognize a status and content of the MED  10 .  
     [0062] The contents registered by the inspection center  14  become viewable on the network. Thus, a user may easily obtain an inspection result without going to the medical institution directly or waiting for a notice to be sent by mail etc. The inspection center  14  may recognize how long and how the MED  10  has been used, a method of properly using the MED  10 , and its expiration date, and this function provides a definite inspection. Each user may recognize that the MED that stores his personal information has been definitely processed through registrations of a collection and recycling by the MED vendor  11 .  
     [0063] Second Embodiment  
     [0064]FIG. 3 is a view of a second embodiment according to the present invention showing another mode of share and utilization of a MED  20  among plural users, which has been shipped by a MED vendor  21 . FIG. 4 is a flowchart of a utilization mode of the MED  20  in the second embodiment shown in FIG. 3. This embodiment may also use the same MED as that used for the first embodiment for the MED  20 .  
     [0065] A description will now be given of a first embodiment according to the present invention using flowcharts shown in FIGS. 3 and 4, and a system explanatory view in FIG. 7. A description will be omitted for those elements which are the same as those in the first embodiment. A description will now be given of a system with reference to FIG. 7.  
     [0066] The MED vendor  21  that makes MEDs  20  serves to built a system and manage a server  22  as storage means in the system as well as having an MED information input unit, such as a PC connected to the server  22 .  
     [0067] A distributor  22  who distributes to sell the MEDs  20  may input information through the Internet via the server  22  and a LAN, and has an MED information input unit  26   a , such as a PC.  
     [0068] A medical institution  23 , such as a hospital, may input and output information through the Internet via the server  22  and a LAN, and has an MED information input unit  23   a  and an MED information display  23   b , such as a PC.  
     [0069] An inspection center  14  which inspect the MEDs  20  may input and output information through the Internet via the server  22  and a LAN, and has an MED information input unit  24   a  and an MED information display  24   b , such as a PC. In addition, the inspection center  24  has a MED result reader  24   c  and MED inspection unit  24   d  for inspecting the MEDs  10 .  
     [0070] The patient (or individual user)  25  is configured to input information through the Internet via the server  22  and the LAN, and has MED information input unit  25   a  and medical inspection information display  25   b , such as a PC.  
     [0071] A description will be given of a system flow.  
     [0072] The MED vendor  21  makes the MED  20  (step S 401 ), and assigns an ID to the MED  20  (step S 202 ). The MED vendor  21  registers the ID assigned to the MED  20  in the server  22  (step S 403 ) as well as usage and use term (or lifetime) unique to this MED  20  (step S 403 ). After this registration, the MED vendor  21  ships the MED  20  (step S 404 ).  
     [0073] The distributor  26  stores the shipped MEDs  20  for delivery. The MED vendor  21  may serve as the distributor  26 . The distributor  26  registers information on a process of circulation, such as temperature control, room temperature exposure time, and shipping agents and dates, with IDs as keys in the server  22  (step  405 ). The distributor delivers the MEDs  20  to the medical institution  23 , such as a hospital and clinic (step S 406 ).  
     [0074] The medical institution  13  as a purchaser, such as a hospital and a clinic, directly sells MEDs  20  (step S 407 ), and registers information, such as a sales date, a purchaser (or a name of a patient), in the server  22  using an ID as a key (step S 408 ). The patient (or individual user)  25  himself uses the MED  20  sold from the medical institution  23  as the above purchaser (step S 409 ). Prior to the use, he retrieves usage and expiration date of the MED  20  using the ID as a key and views reference information for use with the MED  20  (step S 410 ). The patient (or individual user)  25  uses the ID as a key to register a use status and date in the server (step S 411 ), and informs the medical institution (or doctor of a hospital or clinic)  23  of the ID of the used MED  20  (step S 412 ). A system that serves as a specific informing means registers the notification in the server  22  using the ID as a key in the server  22 , and informs the medical institution  23  of the information.  
     [0075] The patient (or individual user)  25  delivers the MED  20  to the inspection center or institution  24  (step S 413 ). The inspection center or institution  24  that receives the delivery uses an ID as a key to register a delivery statue and condition, such as a shipping state, temperature control state, and a time period and the number of days required, in the server  12 . The inspection center  24  inspects the MED  20  (step S 415 ), and registers the inspection result in the server  22  (step S 216 A). The inspection center  24  disposes the useless MED  20  (step S 417 ), and registers the disposal state, method, date and time, etc., in the server  22  (step S 418 ).  
     [0076] Alternatively, the inspection center  24  delivers the MEDs  20  without disposal to the MED vendor  21  for recycling (step S 418 ). The MED vendor  21  recycles the MED  20  by processing the MED  20  so as to enable it to be recycled, and registering in the server  22  whether individual information, such as patient&#39;s personal information (or genetic information), has been properly processed. The process relating to recycling is similar to the first embodiment.  
     [0077] The medical institution  23  (such as a doctor) may use an ID as a key to view the inspection result of the MED  20  registered by the inspection center  24  (step S 416 B). The patient  25  may also view the inspection result of the MED  20  registered by the inspection center  24  using the informed ID as a key (step S 416 C). The patient  25  may also confirm that the MED  20  has been properly processed.  
     [0078] The above embodiment uses a system etc. that uses a network, e.g., LAN, using the Internet shown in FIG. 7 to enable the MED vendor  21 , the distributor  26 , the patient (or individual user)  25 , etc. to write such information about the MEDs  20  as an ID, usage, lifetime, information on a process of circulation, and inspection information, down in the storage means in&#39;the server  22 . Thereby, it uses an ID of the MED  20  as a key to remotely write particular additional information in the server  22  through input means provided in these MED vendor  21 , distributor  26 , patient (or individual user)  25 , etc. via the network.  
     [0079] In this way, the MED vendor  11 , the distributor  26 , the patient (or individual user)  25 , and the inspection center  24  share information using an ID of the MED as a key which has been registered in the server  22  on the network. This system enables an ID of one MED to be commonly used for a plurality of cites, and a plurality of users to use the ID as a key to register, view and utilize information of the MED  20 . Thereby, the MED vendor  21  may manage an expiration date and use status of each shipped MED  20 , and the seller may readily recognize a shipping status from the MED vendor  21 . Each patient (or individual user)  25  may recognize a status and content of the MED  20  to be used. The contents registered by the inspection center  24  become viewable on the network. Moreover, the patient (or individual user)  25  may share information with a doctor of the medical institution  23  for easy inspection.  
     [0080] Since the information is readily shared with the medical institution  23 , a prompt care would be expected in abnormal time. The inspection center  24  may recognize how long and how the MED  20  has been used, and this function is useful for a careful inspection. Each patient (or individual user) may recognize that the MED that stores his personal information has been securely processed through registrations of a collection and recycling of the MED vendor  21 .  
     [0081] As many apparently widely different embodiments of the present invention can be made without departing form the sprit and scope thereof, it is to be understood that the invention is not limited to the specific embodiments thereof except as defined in the claims.
