Furthermore, in recent years, the number of medical equipment and medicines has already reached an enormous level and is still increasing.
The present inventors have come to realize that in the present situation the registration of medical equipment or medicines in the database in a medical facility cannot often be made in time for the use of the products newly introduced or there may be failed or missing registrations, which disturb the convenience and accuracy expected of identification information used in the system. Under such circumstances, doctors and nurses have to undergo a complex and time-consuming process of temporarily stopping the use of a medical equipment or medicine to be used, registering the new medical equipment or medicine in the database and again reading the identification information thereon before use.
The present invention has been made in view of the foregoing circumstances and a general purpose thereof is to provide a technology which ensures medical action and treatment without interruption even when the identification information on medical equipment and medicine to be used in the medical action and treatment is not yet registered in the database.
In order to solve the above problems, a medical data management system according to one embodiment of the present invention includes a first medical information management apparatus and a second medical information management apparatus, and the first medical information management apparatus includes: a first database which contains a plurality of first master data in which identification information on a plurality of medical equipment have been associated with medical equipment information; and a first transceiver which transmits or receives information to or from the second medical information management apparatus. The second medical information management apparatus includes: a second database which contains a plurality of second master data in which identification information on a plurality of medical equipment have been associated with medical equipment information; an acquisition unit which acquires the identification information attached to the medical equipment; a verification unit which verifies whether the identification information acquired by the acquiring unit is contained in the second database or not; and a second transceiver which transmits or receives information to or from the first medical information management apparatus. When the identification information is not contained in the second database as a result of verification by the verification unit, the second transceiver transmits to the first medical information management apparatus an inquiry request signal with which to inquire about whether the identification information not contained in the second database is contained in the first master data or not.
Another embodiment of the present invention relates to a medical data updating system. This medical data updating system includes a first medical information management apparatus and a second medical information management apparatus, and the first medical information management apparatus includes: a first database which contains a plurality of first master data in which identification information on a plurality of medical equipment have been associated with medical equipment information; an update data generator which extracts part of the plurality of first master data so as to generate update data; and a transmitter which transmits the update data to the second medical information management apparatus. The second medical information management apparatus includes: a receiver which receives the update data transmitted from the first medical information management apparatus; a second database which contains a plurality of second master data in which identification information on a plurality of medical equipment have been associated with medical equipment information; an update determination unit which determines whether the second master data contained in the second database are to be updated or not; and an updating unit which updates the second master data contained in the second database, based on the update data, when it is determined that the updating is necessary as a result of the update determination unit.
It is to be noted that arbitrary combinations of the aforementioned constituting elements and the implementations of the invention in the form of method, apparatus, system, computer program, data structure and so forth are effective as and encompassed by the embodiments of the present invention.
Embodiments will now be described by way of examples only, with reference to the accompanying drawings which are meant to be exemplary, not limiting and wherein like elements are numbered alike in several Figures in which:
The invention will now be described by reference to the preferred embodiments. This does not intend to limit the scope of the present invention, but to exemplify the invention.
Before a specific description is given of embodiments of the present invention, a medical data management system to which the embodiments are applicable will be outlined below. A medical data management system according to the present embodiments includes a first medical information management apparatus which manages, in a unified manner, data on medical equipment and the like belonging to a plurality of medical facilities (hereinafter referred to as “equipment master management apparatus”), a second medical information management apparatus which manages data on medical equipment and the like at each medical facility (hereinafter referred to as “hospital master management apparatus”), and a plurality of mobile terminals which are wirelessly connected to a hospital master management apparatus.
Here, the “second medical information management apparatus” includes personal computers and general-purpose computers, such as workstations, which perform the management of medical equipment and the like installed in a hospital or other medical facility. The “first medical information management apparatus”, which is an apparatus performing an overall management of data on medical services at a plurality of medical facilities, includes personal computers and general-purpose computers, such as workstations. The “medical equipment” meant here are not only the ordinary equipment used in medical services but also anything used in medical actions, which include medicines and gases. And the “medical actions” may be any of the actions taken for patients or quasi-patients at medical facilities, such as surgery, inspections, treatment, medication and nursing care.
Individual mobile terminals are used for the checking or the like of medical equipment on the spot of medical services where a variety of medical actions are taken. Such checking is done for the purpose of preventing medical mishaps due to mistaken use of medical equipment or other careless mistakes. Also, the checked medical equipment may be consumed or lost by use, so that it is necessary to supplement them. Hence, reporting the checking results to a hospital master management apparatus can cause it to perform automatic inventory management thereof.
Of the numbers of data items of medical equipment managed at an equipment master management apparatus, a hospital master management apparatus and a mobile terminal, the number of data items of medical equipment managed at an equipment master management apparatus is the largest for reasons of the respective characteristics of the apparatuses. The hospital master management apparatus manages only the data on medical equipment necessary for the medical facility where they are installed. And the number of data items of medical equipment managed by a mobile terminal is the same as that by the hospital master management apparatus. This arrangement is based on the consideration that mobile terminals cannot be used in an operating room, for instance, where wireless communication with the hospital master management apparatus cannot be established. Generally speaking, a great variety of medical equipment are used at medical facilities, and there are hundreds of thousands of data items of medical equipment to be managed by an equipment master management apparatus, which manages the medical equipment at all the medical facilities involved. On the other hand, the number of medical equipment used at each medical facility is in the thousands. Moreover, advances in medical equipment are very rapid with new devices arriving one after another, so that it is difficult for each medical facility to manage them all. It may be inefficient for a facility to manage medical equipment which it does not use as well. According to the present embodiment, therefore, the equipment master management apparatus performs management of all the medical equipment involved in a unified manner.
Under circumstances as described above, there are now no small cases where certain items of medical equipment, when checked by a mobile terminal or a hospital master management apparatus, are not registered in the database of the hospital master management apparatus belonging to the facility. In such a case, it is necessary to newly register information on such nonregistered medical equipment. However, if the registration is to be done manually at the scene of actual medical service where the medical equipment is used, the medical action will have to be interrupted, which is not desirable especially in a situation like emergency surgery. Besides, human errors can result from hasty manual registration during the current busy operation. According to the present invention, therefore, such errors are avoided by autonomous updating in place of manual registration.
In the present embodiment, when a mobile terminal has detected any nonregistered medical equipment which is not being managed by a hospital master management apparatus, the hospital master management apparatus installed in that particular medical facility makes an inquiry to the equipment master management apparatus. At this time, the hospital master management apparatus keeps in memory the identification information on the nonregistered medical equipment as “nonregistered medical equipment” until information concerning the nonregistered medical equipment is received from the equipment master management apparatus. This is because information concerning the nonregistered medical equipment may not always be sent immediately from the equipment master management apparatus. Unless the identification information on the nonregistered medical equipment is stored in memory in preparation for such a delay, another nurse or the like who uses the same nonregistered medical equipment may decide that it is nonregistered again. In such a case, the inquiry about the same nonregistered medical equipment to the equipment master management apparatus may be repeated, thus reducing the efficiency of the system as a whole. Note here that “identification information” used herein means information contained in a part of a code information printed on or attached to an individual medical equipment, which may include a number or the like for identifying the medical equipment.
Further, upon receipt of information concerning the nonregistered medical equipment from the equipment master management apparatus, the hospital master management apparatus makes an updating decision and then carries out an updating processing. This arrangement, which permits accurate updating processing with little human intervention, can effectively prevent human errors. This also ensures speedy medical actions without causing unnecessary trouble to doctors and nurses. Moreover, this ensures accurate data management of medical equipment. Hereinbelow, a detailed description with reference to drawings will be given of the structure and operation of a medical data management system according to the present embodiment.
Using a configuration like this, accurate data management of medical equipment may be accomplished with a minimal amount of human intervention. Especially when a nonregistered device is used within a medical facility, automatic updating of the system may be performed without adding any trouble of maintenance.
Now, the updating of medical data when identification information read by the read unit 344 of a mobile terminal 102 from a medical equipment is not in the storage unit 358, that is, when the medical equipment is a nonregistered medical equipment, will be explained with reference to FIGS. 5 to 8.
After code information on a medical equipment is read, the cutout unit 346 cuts out the only information necessary for later verification (S12). Here “information necessary for verification” means identification information that can be checked against medical equipment stored in the storage unit 358, which may include not only an identification number or product name for identification of the medical equipment but also the producing country, maker name, product number, lot number, expiration date, or the like. Then the terminal verification unit 354 checks to see if the cutout information is contained in the storage unit 358 (S14). As a result of this checkup, when a verification has been made (Y of S16), the terminal display unit 350 displays the name and identification information of the medical equipment on a display medium such as the display of the terminal (S18). On the other hand, when a verification has not been made (N of S16), the terminal display unit 350 displays the information indicating the failure of verification and the identification information itself (S20). Further, the terminal recording unit 356 records the medical equipment meant by the identification information as a nonregistered medical equipment in the transaction data in the storage unit 358 (S22). The third transceiver 348 transmits the identification information on the nonregistered medical equipment to the PC 110 (S24).
The series of operation of a mobile terminal 102 as described above may ensure speedy medical actions by saving the trouble of a nurse or any other performer of a medical action interrupting his or her action to carry out the registration of a nonregistered medical equipment.
Further, when the user having seen this display instructs the input/output unit 252, such as a keyboard, to indicate an intention of inquiry to the equipment master management apparatus 140 (S58), the recording unit 256 records the not-verified identification information as a nonregistered medical equipment in the second transaction data 244 (S60). Also, the second transceiver 248 transmits to the equipment master management apparatus 140 an inquiry request signal about whether or not the identification information not contained in the second master data 242 is contained in the first master data 142 (S62). This inquiry request signal includes identification information and the like concerning the nonregistered medical equipment.
The operation of the PC 110 as described above accomplishes the updating processing of nonregistered medical equipment with little human intervention. The retention of the information on nonregistered medical equipment helps avoid the repetition of the same trouble when a nonregistered medical equipment is recognized again. Moreover, this arrangement makes it impossible for a third party to falsify the information on medical equipment with malicious intent.
By employing the embodiment described as above, the medical actions can be conducted without interruption even when the identification information on medical equipment and medicine to be used in the medical treatment and action is not yet registered in the database. The number of items of master data stored in the PC 110 can be minimized. Automatic updating can reduce the maintenance work for the medical equipment data.
Now, a modified version of a medical data updating system according to an embodiment of the present invention will be described. The explanation of parts identical to those of the preceding description of the embodiments will be simplified by the use of identical reference numerals.
Firstly, a medical data updating system to which the modification of the present embodiment is applicable will be outlined. A medical data updating system according to the present embodiment includes an equipment master management apparatus which manages data on medical equipment and the like belonging to a plurality of medical facilities, a PC 110 which manages medical data and the like at each medical facility and a plurality of mobile terminals which are wirelessly connected to the PC 110. Note here that the devices used for medical treatment have their respectively defined insurance points which serve as the basis of calculation of medical costs when such medical equipment are used. These insurance points are updated altogether at a predetermined time once every two years, and there are a large number of medical equipment to be updated. Thus, if the updating of the insurance points is to be managed by each medical facility, then there will be a great burden on both the human staff and the system involved at the time of updating. Besides, there may result problems of failed or missing updating since the insurance points of most of the medical equipment are to be changed.
Advances in the research and development of medical equipment are very rapid with new devices arriving one after another, so that it is difficult for each medical facility to manage them all. Furthermore, as mentioned already, a great variety of medical equipment are used at medical facilities, and there are hundreds of thousands of data items of medical equipment to be managed by an equipment master management apparatus, which manages the medical equipment at all the medical facilities involved. In fact, it is difficult, and very inefficient, for each of the medical facilities to manage the updating of all the medical equipment. Hence, the equipment master management apparatus performs the updating management of all the medical equipment involved in a unified manner.
According to a modification of the present embodiment, therefore, the equipment master management apparatus performs the updating management in a unified manner when the insurance points of medical equipment are to be updated and when new medical equipment is to be introduced. And the PC 110 installed in each medical facility determines whether updating processing is necessary or not based on an update request from the equipment master management apparatus and other information concerning the insurance points of medical equipment to be updated and the like and carries out the updating processing only when it is found necessary. In this manner, the equipment master management apparatus performs updating management in a unified manner, so that burden on each facility involved can be lightened even when the insurance points of a plurality of medical equipment are to be updated together. Moreover, freedom from human intervention reduces burden on the personnel involved and human errors. Furthermore, each medical facility can respond flexibly because it is allowed to perform updating following its decision on updating. Hereinbelow, the structure and operation of a medical data updating system according to a modification of the present embodiment will be described in detail with reference to the drawings.
Similar to the medical data management system as shown in
Now, the updating operation example of a medical data updating system is explained with reference to
Firstly, the update data generator 152 at the equipment master management apparatus 140 generates update data by extracting part of a plurality of first master data 142 (S90). “Extracting part of first master data 142” means the extraction from first master data 142 of medical equipment whose insurance points are to be changed, out of the medical equipment used by the PC 110 to be updated. And the update data includes not only the management apparatus identification information on the PC 110 to be updated but also the names, identification information, update date and time, insurance points and the like of medical equipment to be newly added. Then the first transceiver 148 transmits update data to the PC 110 to be updated (S92).
Next, in the PC 110 the second transceiver receives the update data sent from the equipment master management apparatus 140 (S94). Then the update determination unit 258 determines, based on the update data, whether the second master data 242 contained in the second database 246 are to be updated or not. Here, “based on the update data” means that it is determined whether or not the management apparatus identification information contained in the update data is in agreement with the identification information on said PC 110 managed by the management unit 262 (S96). It further means that it is determined whether or not the update date and time is in agreement with the system date and time of said PC 110 managed by the management unit 262, whether or not the update date and time is older than the system date and time thereof (S98) or the like.
Here, when the management apparatus identification information contained in the update data is not in agreement with the identification information on the PC 110 managed by the management unit 262 (N of S96), the PC 110 belongs to a medical facility which should not be updated and therefore ends the operation without being updated. And when the management apparatus identification information contained in the update data is in agreement with the identification information on the PC 110 managed by the management unit 262 (Y of S96) and the update date and time contained in the update data is not in agreement with the system date and time of the PC 110 managed by the management unit 262 and besides the update date and time is new (N of S98), it is not yet the time for updating and thus no updating is done. On the other hand, when the management apparatus identification information contained in the update data is in agreement with the identification information on the PC 110 managed by the management unit 262 (Y of S96) and the update date and time contained in the update data is in agreement with the system date and time of the PC 110 managed by the management unit 262 or the update date and time is older than that (Y of S98), it is decided to be the time for updating and the updating unit 260 updates the second master data 242 contained in the second database 246 by the update information on the medical equipment contained in the update data (S99).
By implementing the above structure and operation, accurate updating can be accomplished even when updating of a large number of medical equipment must be done following a revision of insurance points. This will reduce the burden on the personnel and the load on the system in carrying out the updating processing. Moreover, this will reduce the possibilities of failed updating or updating error. And each medical facility can respond flexibly because it is allowed to perform updating processing following its decision on updating. Further, timely updating can be carried out even when new medical equipment are arriving one after another. It is not necessary for each medical facility to conduct the whole management.
The above description of a modification of the present embodiment is such that when there has been a revision of insurance points of medical equipment or when new medical equipment have been added, an equipment master management apparatus 140 starts updating processing for a PC 110 and the PC 110 carries out the updating processing by referring to the update date and time or the like. However, the modification is not limited thereto, and the equipment master management apparatus 140 may notify the PC 110 of the presence of update data when there has been a revision of insurance points of medical equipment or when new medical equipment have been added. In this case, the equipment master management apparatus 140 may generate and transmit update data only when it has received an update request from the PC 110. An update request from the PC 110 may be initiated by the input of an instruction from the user, for instance. The arrangement as described above allows the PC 110 to perform the updating processing independently and flexibly. The equipment master management apparatus 140 only has to perform the management of data, which makes the system design simpler with clear division of roles with the PC 110.
The present invention has been described based on the embodiments and their modifications. These embodiments are merely exemplary, and it is understood by those skilled in the art that various other modifications to the combination of each component and process thereof are possible and such modifications are also within the scope of the present invention.
While the preferred embodiments of the present invention have been described using specific terms, such description is for illustrative purposes only, and it is to be understood that changes and variations may be made without departing from the spirit or scope of the appended claims.
