[0031]
The leasing / collecting company 20 is a company that purchases the medical device (biopsy forceps) 1 from the supplier 10 and lends it to a plurality of facilities 30. In addition, the used medical device 1 is collected from each facility 30. Each medical device 1 can be reused a predetermined number of times by performing a sterilization operation. However, one medical device 1 is always re-rented to the same facility 30.
[0032]
Each facility 30 is a hospital or the like that uses the medical device 1 lent by the leasing / collecting company 20.
[0033]
The sterilizer 40 is a supplier that sterilizes the medical device 1 purchased or collected by the leasing / collecting company 20. In this case, as described above, the lending destination of each medical device 1 is determined in a one-to-one relationship, but this sterilizer 40 sterilizes the medical device 1 for each lending destination separately from other lending destinations. There is no need to perform the work, and all the medical devices 1 of all the borrowers are sterilized collectively. The sterilized medical device 1 is sorted by the leasing / collecting company 20 to which the sterilized medical device 1 is delivered.
[0034]
FIG. 1A is a block diagram showing a configuration of a medical device reuse management system according to the first embodiment of the present invention.
[0035]
That is, the leasing / collecting company 20 includes a server 21 and a database (hereinafter abbreviated as DB) 22, and each medical device 1 is rented to which facility (hospital) 30 and how many times it is used. It is designed to manage information such as what has been done. The server 21 can be connected to a personal computer (hereinafter abbreviated as a PC) 11 of the supplier 10 and a PC 31 of each facility (hospital) 30 via a network 50 such as the Internet. Information about the tool 1 can be browsed.
[0036]
In the leasing / collecting company 20, a plurality of PCs 23 (only one is shown for the sake of simplicity in the figure) are connected to the server 21, and at the time of lending to the facility (hospital) 30, Identification information (hereinafter referred to as individual ID) such as a device unique number assigned to each medical device 1 as a barcode can be read by a barcode reader 24 connected to each PC 23 and registered in the DB 22. Yes.
[0037]
That is, when the medical device (biopsy forceps) 1 is manufactured by the supplier 10 or purchased by the leasing / recovery company 20, the medical device (biopsy forceps) 1 includes (B ), A barcode label 2 on which a barcode indicating the individual ID is affixed is attached to the predetermined position. The bar code label 2 is fixed by being applied over the entire circumference (partially overlapped) or covered with a heat-shrinkable tube or the like so that it does not peel off during sterilization by the sterilizer 40. Need to be solid.
[0038]
The medical tool (biopsy forceps) 1 is housed in a sealed sterilization bag 3 and returned from the sterilizer 40 to the rental / collector 20 as shown in FIG. In this state, the facility (hospital) 30 is lent out. For this reason, the barcode written on the barcode label 2 is a pattern having a length of ½ or more of the circumference of the medical instrument (biopsy forceps) 1, and the medical instrument (biopsy forceps) 1 Regardless of the orientation and rotation angle stored in the sterilization bag 3, the bar code reader 24 can read from the upper surface of the sterilization bag 3.
[0039]
In addition, on the upper surface of the sterilization bag 3, a notation indicating the type of the medical device 1 and a notation indicating sterilization have been made. As described above, in the sterilizer 40, it is not necessary to manage at what facility (hospital) 30 the medical device (biopsy forceps) 1 is lent and how many times it has been used. The sterilization work can be performed in a lump, and the medical tool (biopsy forceps) 1 stored in the sterilization bag 3 after the sterilization work can be returned to the leasing / recovery company 20 in a lump. In the leasing / collecting company 20, the barcode (individual ID) on the barcode label 2 affixed to the medical device (biopsy forceps) 1 stored in the sterilization bag 3 by the barcode reader 24 connected to the PC 23. ), It is possible to know the facility (hospital) 30 where the medical tool (biopsy forceps) 1 with the individual ID should be lent from the DB 22 via the server 21. That is, the DB 22 includes the individual ID and the facility identification information (hereinafter referred to as the facility ID) assigned to the facility (hospital) 30 where the medical tool (biopsy forceps) 1 with the individual ID is to be lent. It is stored in association. Thus, the leasing / collecting company 20 prints the barcode label 4 on which the barcode indicating the facility ID is printed, and affixes the barcode label 4 to a predetermined position (facility ID sticking position) 5 on the sterilization bag 3. It is like that. The bar code label 4 is preferably printed with a facility name so that the facility (hospital) can be recognized by human eyes.
[0040]
(C) of FIG. 2 is a figure which shows an example of the registration content of said DB22. That is, for each medical device 1, the facility ID is registered in association with the individual ID, and the use result data of the medical device 1 is accumulated. Here, the usage record data includes the shipping date at each use count and other information (remarks). For example, the medical device 1 with the individual ID “DT1000001” starts to be delivered to the facility (hospital) 30 with the facility ID “HP1200001” on “March 8, 2002”, and the usage limit is set to “May 13, 2002” The number of times (24 times) was lent out, and it was found that the usage limit number was exceeded on “May 21, 2002”, and it was discarded. In this case, the disposal date is registered as the shipping date of the 25th use (the number of times of use is “24 times”), and the fact of disposal is recorded as a remark. In addition, the medical device 1 with the individual ID “DT1000002” started to be delivered to the facility 30 with the facility ID “HP1011001” on “May 10, 2002”, and the second delivery record on “May 18, 2002”. There is something. The medical device 1 with the individual ID “DT1000003” has been delivered to the facility 30 with the existing facility ID “HP1200001” as an alternative to the medical device 1 with the individual ID “DT1000001”. The medical device 1 having the individual IDs “DT1000004” to “DT1000006” is an unused item.
[0041]
FIG. 3 is a flowchart illustrating a business flow by the medical device reuse management system according to the first embodiment of the present invention.
[0042]
That is, the leasing / collecting company 20 assigns an individual ID to the medical device (biopsy forceps) 1 newly purchased from the supplier 10 or entrusts it to the supplier 10 (step S1). . When the supplier 10 is entrusted, the supplier 10 assigns an individual ID to the target medical device 1 and affixes a bar code label 2 indicating it as a bar code, and then sells it to the leasing / collecting company 20. Will be.
[0043]
Then, the leasing / collecting company 20 sterilizes and stores the medical device 1 given the individual ID in the sterilization bag 3 or entrusts the sterilization company 40 to sterilize and stores the sterilization bag 3 (step). S2). That is, the sterilizer 40 entrusted by the leasing / recovering company 20 performs sterilization work on the entrusted medical device 1, puts it in the sterilization bag 3, and returns it to the leasing / recovering company 20. That is, since the newly purchased medical device 1 is sterilized, it can be used as a safer medical device.
[0044]
The leasing / collecting company 20 reads the individual ID assigned to the medical device 1 with the barcode reader 24 while the medical device 1 is stored in the sterilization bag 3, and is stored in the server 21 connected to the PC 23. It is discriminated against the existing DB 22 to determine whether the medical device 1 is an unused product or an used product (step S3).
[0045]
Here, if it is an unused item (step S4), the medical device 1 is stocked for a new customer or as an alternative to an existing facility (step S5).
[0046]
On the other hand, when selling or renting the medical device 1 to a new customer, that is, a new facility (hospital) 30, the leasing / collecting company 20 stores the new facility ID in the server 21 connected to the PC 23. Set in DB22 (step S6). That is, here, not only a reuse type but also a disposable medical device 1 can be handled in the same manner. That is, in the disposable medical device 1, the limit of the number of times of use may be set to “one time”.
[0047]
Then, the stock item stocked in step S5 is allocated to the new facility (hospital) 30, and the individual ID of the stock item is associated with the facility ID set in step S6 on the DB 22 (step S7). ). Thereafter, the number of uses is increased by 1 on the DB 22, and the associated facility ID is read on the DB 22 (step S8), and the medical device 1 is sorted and delivered for each of the read facility IDs. (Step S9). Thereby, the medical device 1 allocated from the inventory is lent out to the new facility (hospital) 30.
[0048]
At each facility (hospital) 30 to which the medical device 1 has been delivered, the medical device 1 is taken out from the sterilization bag 3 and used (step S10). At this time, the sterilization bag 3 from which the medical device 1 is taken out is discarded. The used medical device 1 is collected by the rental / collection company 20 (step S11).
[0049]
Thus, for the used medical device 1 collected from each facility (hospital) 30, the flow is repeated from step S2. That is, the leasing / recovery company 20 sterilizes the collected medical device 1 and stores it in the sterilization bag 3, or entrusts the sterilization company 40 to sterilize and stores it in the sterilization bag 3.
[0050]
Then, when the leasing / collecting company 20 reads the individual ID of the medical device 1 stored in the sterilization bag 3, it collates with the DB 22 stored in the server 21 connected to the PC 23 (step S3), When it is determined that the medical device 1 is an already-used product (step S4), it is determined from the DB 22 whether the number of uses of the medical device 1 with the individual ID has reached a predetermined number of times of use. (Step S12).
[0051]
As a result of the determination, if it is determined that the use limit number has not yet been reached (step S13), the process proceeds to step S8, the use number is increased by one on the DB 22, and the association is made on the DB 22. Read the facility ID. Then, for each of the read facility IDs, the medical device 1 is sorted and delivered (step S9).
[0052]
In this way, until the medical device 1 is rented for the number of times of use limit, it is lent out to the corresponding specific facility (hospital) 30 and is repeatedly collected and sterilized.
[0053]
Thus, when the number of uses of the medical device 1 reaches a predetermined use limit number (step S13), the medical device 1 is discarded as a waste product and discarded (step S14). Then, as an alternative to the discarded medical device, the inventory stocked in step S5 is replenished (step S15). That is, the DB 22 associates the individual ID of the inventory with the facility ID of the waste. After that, it progresses to said step S8 and repeats said operation | movement.
[0054]
In this way, the collected used medical device 1 is not discarded as it is, but is sterilized and then discarded. Thereby, the medical device 1 to be discarded can be discarded not as medical waste but as general industrial waste.
[0055]
FIG. 4 is a diagram showing an operation flowchart of the PC 23 of the leasing / collecting company 20 for performing the operation as described above. In this example, the barcode label 2 is read and automatically sorted while the sterilized medical device 1 is conveyed by a belt conveyor or the like. Of course, the reading and sorting work itself may be performed manually. good.
[0056]
That is, first, the individual ID of the conveyed medical device 1 is read by the bar code reader 24 connected to the PC 23 (step ST1), and it is searched whether or not the read individual ID is registered in the DB 22. (Step ST2). The processing in step ST1 and step ST2 corresponds to the operation in step S3.
[0057]
If the read individual ID is not registered in the DB 22 (step ST3), the read individual ID is registered in the DB 22 (step ST4), and the use count n is set to 0 (step ST4). Step ST5). And the said medical device 1 (sterilization bag 3 which accommodated) is sorted as a stock item. The processes in steps ST4 to ST6 correspond to the operation in step S5. In the case of manual sorting, in the above-described step ST6, if a display instructing to be in stock is made on the display device (not shown) of the PC 23, the sorting person can see it. Sorting becomes possible.
[0058]
When the read individual ID is already registered in the DB 22 (step ST3), the facility ID corresponding to the individual ID is read from the DB 22 (step S7). Then, the use number n registered in the DB 22 is compared with a predetermined use limit number G (step ST8). The process in step ST8 corresponds to the operation in step S12.
[0059]
Here, if the use number n is not equal to the use limit number G, that is, if the use number n has not reached the use limit number G (step ST9), the use number n is incremented by "+1" (step ST10). The read facility ID is displayed on the display device (not shown) of the PC 23 together with the individual ID (step ST11). The processes in steps ST9 and ST10 and step ST7 correspond to the operation in step S8.
[0060]
Then, the barcode label 4 indicating the read facility ID is printed and pasted on the facility ID pasting position 5 of the sterilization bag 3 (step ST12), and automatic sorting is performed for each lending facility, Is registered in the DB 22 as the last shipping date (step ST13). The processing in step ST12 and step ST13 corresponds to the operation in step S9. In the case of manual sorting instead of automatic sorting, the sorting person can see the facility ID displayed in step ST11 to enable sorting.
[0061]
On the other hand, when it is determined in step ST9 that the use number n has reached the use limit number G, the medical device 1 (sterilization bag 3) is sorted as a waste product (step ST14). The process in step ST14 corresponds to the operation in step S14. In the case of manual sorting instead of automatic sorting, in this step ST14, if a display instructing that the product is to be discarded is displayed on the display device (not shown) of the PC 23, the sorting person can Sorting is possible by looking at it.
[0062]
Then, one medical device 1 sorted as an inventory is extracted, and the individual ID is read by the barcode reader 24 (step ST15). Thereafter, the facility ID read in step ST7 is registered in the DB 22 in association with the read individual ID (step ST16), and the process proceeds to step ST10. The processing in step ST15 and step ST16 corresponds to the operation in step S15.
[0063]
As described above, according to the first embodiment, the individual medical device 1 is assigned with an individual ID, and the individual ID assigned at the time of lending or selling and the facility ID for lending or selling are associated with each other in the DB 22. , And the server 21 performs centralized management so that the sterilizer 40 can perform the sterilization work in a batch rather than for each facility 30. Even if the sterilization work is performed collectively, each medical device 1 can be re-rented to the correct facility 30 by the individual ID and the facility ID. Further, since it is possible to grasp whether or not the use limit (durability) has been reached from the individual ID of each medical device 1, it is easy to replace a reused product that has been used for the use limit with a new one. In this way, it is possible to eliminate the complexity of the work required for the sterilization work of the medical device and the disposal / reuse determination.
[0064]
In addition, when the medical device 1 that has been used for the above-mentioned number of times of use is discarded, it is not collected as it is from the facility 30, but is sterilized by the sterilizer 40 and discarded. It is not considered and has the advantage of being easy to dispose of.
[0065]
Furthermore, it can be easily grasped from which facility 30 each product (medical device 1) has been rented from the PC 11 of the supplier 10 as well. Furthermore, if the information about the return of each product (medical device 1) used in the facility 30 to the collection company 20 is stored in the DB 22 via the network 50, where the medical device 1 is located now. Can be easily ascertained by accessing the server 21 via the network 50, which also has the advantage of ensuring traceability.
[0066]
[Second Embodiment]
Next, a second embodiment of the present invention will be described.
[0067]
In the second embodiment, as shown in FIG. 5A, the used medical device 1 from each facility (hospital) 30 is not collected by the renter 20 ′ but collected / recovered. This is an example where the sterilizer 40 'performs the operation.
[0068]
FIG. 6 is a flowchart for explaining a business flow by the medical device reuse management system according to the second embodiment of the present invention.
[0069]
That is, the leaser 20 ′ gives an individual ID to the medical device (biopsy forceps) 1 newly purchased from the supplier 10 or entrusts it to the supplier 10 (step S1 ′). . Then, the leaser 20 'entrusts the collection / sterilization contractor 40' to sterilize the medical device 1 to which the individual ID is assigned (step S2A).
[0070]
The collection / sterilization contractor 40 ′ entrusted by the leaser 20 ′ performs sterilization work on the entrusted medical device 1, puts it in the sterilization bag 3, and returns it to the leaser 20 ′ (step S2B). .
[0071]
The renter 20 ′ reads the individual ID assigned to the medical device 1 with the barcode reader 24 while the medical device 1 is stored in the sterilization bag 3, and is stored in the server 21 connected to the PC 23. It is compared with the existing DB 22 to determine whether the medical device 1 is an unused product or an used product (step S3 ′).
[0072]
Here, if it is an unused item (step S4 '), the medical device 1 is stocked for a new customer or as an alternative to an existing facility (step S5').
[0073]
On the other hand, when selling or renting the medical device 1 to a new customer, that is, a new facility (hospital) 30, the leaser 20 ′ stores the new facility ID in the server 22 connected to the PC 23. (Step S6 ′).
[0074]
Then, the stock item stocked in step S5 ′ is allocated to the new facility (hospital) 30, and the individual ID of the stock item is associated with the facility ID set in step S6 ′ on the DB 22 ( Step S7 '). Thereafter, the number of uses is increased by one on the DB 22, and the associated facility ID is read on the DB 22 (step S8 ′), and the medical device 1 is sorted and delivered for each of the read facility IDs. (Step S9 ′). Thereby, the medical device 1 allocated from the inventory is lent out to the new facility (hospital) 30.
[0075]
At each facility (hospital) 30 to which the medical device 1 has been delivered, the medical device 1 is taken out from the sterilization bag 3 and used (step S10). At this time, the sterilization bag 3 from which the medical device 1 is taken out is discarded. The used medical device 1 is collected by the collection / sterilization contractor 40 '(step S11').
[0076]
For the used medical device 1 collected from each facility (hospital) 30 in this way, the flow is repeated from step S2 '.
[0077]
When the leaser 20 ′ reads the individual ID of the medical device 1 stored in the sterilization bag 3, it collates with the DB 22 stored in the server 21 connected to the PC 23 (step S3 ′). When it is determined that the medical device 1 is an already-used product (step S4 ′), it is determined from the DB 22 whether the number of uses of the medical device 1 with the individual ID has reached a predetermined number of uses. Perform (step S12 ').
[0078]
As a result of the determination, if it is determined that the use limit number has not yet been reached (step S13 ′), the process proceeds to step S8 ′ to increase the number of use by one on the DB 22 and on the DB 22. Read the associated facility ID. Then, the medical device 1 is sorted and delivered for each read facility ID (step S9 ').
[0079]
In this way, until the medical device 1 is rented for the number of times of use limit, it is rented to a corresponding specific facility (hospital) 30, and collection and sterilization are repeated.
[0080]
Thus, when the number of times of use of the medical device 1 reaches a predetermined use limit number (step S13 '), the medical device 1 is discriminated from the others as a waste product and discarded (step S14'). Then, as an alternative to the discarded medical device, the inventory stocked in step S5 'is replenished (step S15'). Thereafter, the process proceeds to step S12 'and the above operation is repeated.
[0081]
As described above, also in the second embodiment, the same effect as in the first embodiment can be obtained.
[0082]
The present invention has been described above based on the embodiments. However, the present invention is not limited to the above-described embodiments, and various modifications and applications are possible within the scope of the gist of the present invention. It is.
[0083]
For example, the biopsy forceps has been described as the medical tool 1 to be reused, but the present invention can be similarly applied to any other medical reuse tool.
[0084]
Further, the barcode itself printed on the barcode label 2 may be a one-dimensional barcode or a two-dimensional barcode. Alternatively, instead of this bar code, an individual ID may be given by laser marking (marking) or IC tag sticking. When an IC tag is used, the reading may be a contact type or a non-contact type.
[0085]
Further, in the above embodiment, the supply company 10 and the leasing / collecting company 20 or the leasing company 20 ′ are separate, but the supplying company 10 performs the functions of the leasing / collecting company 20 or the leasing company 20 ′ simultaneously. It may be.
[0086]
Further, the server 21 is not provided in the rent / collector 20 or the renter 20 ′, but may be in the supplier company 10, or the supplier company 10, the rent / collector 20 or the renter 20 ′, In addition, it may be provided in an independent service provider company or the like that is separate from the facility (hospital) 30 and can be accessed via the network 50 therefrom.
[0087]
Furthermore, the present invention can be applied not only to the above rental products but also to services for sterilizing medical tools such as biopsy forceps owned by the facility (hospital) 30.
[0088]
Further, the information registration format of the DB 22 is not limited to that shown in FIG. 2C, and any format may be used as long as necessary information is registered. For example, when the use limit number is different for each medical device, it is necessary to register the use limit number in addition to the use number. That is, as shown in FIG. 5B, the use limit number, the use number, the facility ID, the last delivery date, the last entry date, etc. may be registered in correspondence with each individual ID. In the same figure, the medical device 1 with the individual ID “DT100001” returned from the facility (hospital) 30 with the facility ID “HP1200001” on May 19, but was discarded because it reached the limit of use, and as a substitute, The medical device 1 with the individual ID “DT1000002” is delivered to the facility 30 on “May 20, 2002”. The medical device 1 with the individual ID “DT100003” is delivered to the facility 30 with the facility ID “HP1011001” on “May 21, 2002”. Further, the medical device 1 with the individual ID “DT100004” returns to the leasing / collecting company 20 from the facility 30 with the facility ID “HP1200001” on May 19, 2002, and is sterilized by the sterilizer 40. It is in stock after sterilization by the leasing / collecting company 20. The medical devices 1 with individual IDs “DT100005” and “DT100006” are in stock at the rental / collection company 20 as unused items. The last warehousing date may be registered in the DB 22 in step S3 (step ST7) or step S5 (step ST4).
[0089]
In addition, it is determined whether or not the disposal of the medical device 1 has reached the use limit number. However, if the process for increasing the use number on the DB 22 is performed first, whether or not the use limit number has been exceeded. Depending on whether or not it is discarded.
[0090]
As described above, the business flow and the operation of the PC 323 described with reference to the flowchart can be modified and changed as appropriate.
[0091]
Further, since the server 21 and the PC 31 of each facility (hospital) 30 are connected via the network 50, not only information browsing from the PC 31 of the facility 30 but also in the reverse direction, that is, the facility 30 from the server 21 side. Notification of information to the PC 31 is also possible.
[0092]
For example, as shown in FIG. 7, the server 21 searches the DB 22 for an individual ID that has passed a predetermined number of days from the last delivery date, that is, the medical device 1 at a predetermined time every day (step ST21). If not (step ST22), it is determined whether or not the search process for all the individual IDs registered in the DB 22 has been completed (step ST23), and if not, the process returns to step ST21.
[0093]
If an individual ID that has passed a predetermined number of days from the last delivery date is searched (step ST22), it is determined whether or not it has been discarded (step ST24). If it has been discarded, the process proceeds to step S23.
[0094]
On the other hand, in the case where the medical device 1 with the retrieved individual ID has not been discarded, that is, it has not been collected even though the lending period to the facility (hospital) 30 has passed, the facility 30 If information that returns each used product (medical device 1) to the collection company 20 is stored in the DB 22 via the network 50, the corresponding facility ID is read from the DB 22 and specified by the facility ID. The PC 31 of the facility (hospital) 30 to be notified is notified via the network 50 that the lending time limit for the medical device 1 with the individual ID has passed (step ST25).
[0095]
That is, the sterilization of the sterilization bag 3 guarantees the sterility of the medical device 1 accommodated in the sterilization bag 3, and the sterilization is normally maintained semipermanently. Therefore, in view of the use in which medical safety is more strongly demanded, it is preferable to collect in about one month from the loan date regardless of use. By performing the warning notification as described above, collection failure can be prevented.
[0096]
In addition, instead of searching for and notifying items that have passed the collection deadline, the individual ID of the medical device 1 scheduled to be collected may be notified to the PC 31 of each facility (hospital) 30 every day.
[0097]
