Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a management method or management support system for medical items related to surgery in a hospital, and more particularly, to a management method for minimizing insurance claim omissions and appropriately managing information on medical items. Or, it relates to a management support system.
[0002]
[Prior art]
In hospitals, a wide variety of extremely diverse types of medical articles are used, and particularly, a large amount of diverse medical articles are used in a limited time in surgery. Therefore, it is extremely troublesome to accurately record these used articles in a short time, which imposes a heavy burden on nurses and other medical personnel. In particular, it is a serious problem in any hospital that leakage of insurance claims for articles used for surgery is a serious problem, and in some cases, management of the hospital may be squeezed.
[0003]
Conventionally, it has been attempted to attach a barcode to a medical article and manage the barcode. However, with the barcode, non-contact reading is possible, but the barcode reader must be brought close to the article each time, and reading is not possible. It is very complicated, and it is not performed to read an article actually used in the operation with a barcode every time. Therefore, it is a fact that what is used is visually identified and managed by picking up the goods used in the surgery. In such manual management, omission of management of used goods and omission of insurance claims occur frequently. are doing.
[0004]
In addition, in the case of surgery, a cart loaded with medical items necessary for the surgery is used, but conventionally, a single cart is shared by a plurality of patients, and the number of items loaded on the cart is conventionally increased. Is over 300, and the cart has become large and takes up space. The above-mentioned visual management was also performed for one week at a time, and tended to be sloppy.
[0005]
[Problems to be solved by the invention]
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and has as its object to manage an article to be used in an operation in a simpler and more reliable manner.
[0006]
[Means for Solving the Problems]
To achieve this object, the technical means adopted by the present invention associates a cart loaded with surgical medical articles with patient information of a patient who performs surgery, and stores article information in the articles loaded on the cart. A non-contact type ID tag is provided, and the article information transmitted from the non-contact type ID tag of the articles remaining in the cart after the operation is wirelessly read and compared with the information of the medical articles loaded on the cart before the operation. Thus, the article used for the operation is managed in association with the patient information.
[0007]
The idea of associating and managing a patient scheduled for surgery and a cart loaded with surgical medical articles is a completely new idea in the industry. The idea of collectively reading and managing the articles used in the operation after the operation is a completely new idea that has never existed before.
[0008]
In a more preferable aspect of the technical means adopted by the present invention, an article card is pasted on all the articles loaded on a cart loaded with a surgical medical article, and the cart card is associated with the articles loaded on the cart and the cart identification information. Issue a patient card associated with specific cart identification information. The article card, the cart card, and the patient card each have a non-contact ID tag storing information, and after the operation, the cart Passing through a tag reader (antenna, scanner) arranged in the form of a gate, the information on the items left in the cart after the operation is read at once and compared with the information on the medical items loaded on the cart before the operation This is characterized in that articles used for the operation are managed together with patient information. In this case, the association between a cart and a patient is performed by assigning a patient card in relation to a selected cart. In one preferred non-limiting example, the storage unit of the computer manages information on the articles loaded on the cart using the cart identification information (cart name) as a key, and stores the information on the articles loaded on the cart before the operation. Information can be managed via a cart card. Further, the system reads information from a cart card including the non-contact ID tag storing the cart identification information and a patient card including the non-contact ID tag storing the cart identification information as one of the information, and reads the card identification information of the cart card. By comparing the information with the cart identification information of the patient card, the correspondence between the used article and the patient is not mistaken.
[0009]
Non-contact type ID tags as described above and means for transmitting and receiving radio frequencies from such tags are known, for example, Japanese Patent Application Laid-Open No. H10-512993, Japanese Patent Application Laid-Open No. H11-144156, and It is disclosed in Japanese Unexamined Patent Publication No. 2000-20839. Preferably, the non-contact type ID is an RFID tag including a data carrier including an IC chip and an antenna (for example, a small dipole antenna). The non-contact ID tag is configured to receive stored radio waves from an antenna to signal stored information and transmit the signal to the antenna. The information received by the antenna is transmitted to a computer via a scanner. Is sent to and analyzed. An S-label (Japan Information System Co., Ltd.) can be used as such a non-contact ID tag. The radio frequency from the S-label is read by a scanner via an antenna and sent to a computer for processing. However, the data carrier that can be adopted in the present invention is not limited to the S-label, but can write data, transmit signalized storage information to the antenna, and maintain a certain distance. Any tag may be used as long as it is a non-contact ID tag capable of receiving and recognizing a signal with an antenna even if it is separated from another, and capable of simultaneously identifying information from a plurality of tags. As for the non-contact type ID tag, in addition to the above-mentioned publications, for example, JP-A-10-269287, JP-A-2000-118633, JP-A-2000-136407, JP-A-2000-259947, and JP-A-2000-272723. No., etc. are also disclosed. In the present invention, the non-contact type ID tag is configured to transmit / receive radio waves to / from an antenna, receive radio waves from the antenna, convert stored information into a signal, and transmit the signal to the antenna. However, this does not exclude a non-contact type ID having a built-in power supply. Further, the shape of the non-contact type ID tag is not limited, and may be a label shape or the tag itself may constitute a card.

If the cart card 4 is held in the corresponding cart, the department name and the cart number can be grasped by looking at the liquid crystal display 4b of the cart card 4.
[0017]
[Issuing a cart card]
The issuance of a cart card will be described. Since the medical articles mainly used for the operation differ depending on the medical departments, the articles to be used are selected according to the medical care database having the medical departments, disease names, and operative methods. Specifically, the master of the articles to be loaded for each medical department cart is input from the article database, the cart number is input, and the cart card is issued. That is, by providing an article master for each cart, article management can be performed for each cart, and frequent changes in article constants and articles can be satisfactorily handled. In a preferred embodiment, the carts are grouped by department, for example, Ophthalmology-No. 1 to No. 10, heart surgery-No. 1 to No. It looks like 10. In this case, the medical department and the cart number constitute the cart identification information. Alternatively, the cart identification information may be constituted only by the number by assigning the number in a serial number for each medical department (for example, 1 to 10 for ophthalmology and 11 to 20 for cardiac surgery). By only issuing a cart card, the cart card merely holds the information on the articles loaded on the cart via the cart identification information, and is not linked to the patient information. It should be noted that the cart identification information may be any number, alphabet, kana or katakana, or any name, so long as it can identify the cart. In addition, a shelf name is input to the master of an article placed on a specific shelf which is a high-priced medical article.
[0018]
[Patient Card]
The patient card 5 is also a business card size card (the size and shape of the card are not limited), and incorporates an S-label exemplified as a non-contact ID tag 5a. The patient card 5 includes a patient ID, a name, and a room number (operating room number). The patient ID, name, and room number are displayed on the liquid crystal display unit 5b. If the patient card 5 is held in the corresponding cart 2, the patient ID, name and room number can be grasped by looking at the liquid crystal display 5b of the patient card 5.
[0019]
[Issuing a patient card]
The issue of a patient card will be described. The patient card is issued by inputting patient information of a scheduled operation (patient information in a narrow sense), specifically, a patient ID, a patient name, and a ROOM when issuing a scheduled operation statement. When a patient card is issued, if the name of a medical department (also referred to as patient information in a broad sense) is input on the operation schedule statement creation screen, the cart name is automatically selected and given. For example, if an ophthalmologist is input as a medical department name, an ophthalmic cart No. No. 1 to No. From No. 10 1 is automatically set and the cart identification information is also stored on the patient card. Thus, a specific cart is selected and associated with the patient via the patient card. By issuing the patient card, the cart information and the patient information are linked.
[0020]
[Data writing device]
Writing and issuing information to and from the non-contact IC tags 3a, 4a, and 5a provided on the article card 3, the cart card 4, and the patient card 5 are performed by a data writing device. A card provided with an S-label is inserted into a data writing device, predetermined data is written and stored in the inserted card, and the card is taken out from the data writing device. The data writer is connected to a computer terminal, and by inputting desired data from an input device of the computer, various cards including a contactless ID tag for storing desired information are issued via the data writer. Is done. Such data writing devices are known.
[0021]
[Exclusive cart]
The cart 2 loaded with medical articles for each patient who performs surgery generally includes a vertically long box-shaped main body, a plurality of drawer trays provided on the front surface of the main body, and running members such as rollers provided at the lower end of the main body. Many kinds of medical items are stored in the drawer tray. The conventional operation cart is made of metal such as stainless steel, but the cart and the drawer tray of the present invention are both made of resin. About 100 to 150 articles are loaded on the cart used for the surgery, and as a result of the experiment, it is necessary to make the cart made of resin in order to reliably read the information of the S-label wirelessly. Came to the conclusion. Attempts have been made to use a metal frame (for example, stainless steel) as the main body and provide a resin tray on this frame. However, in order to reliably read out articles, it is considered that it is preferable that the entire body be made of resin. The cart 2 has, for example, a card holding portion formed on a side surface, and a cart card 4 and a patient card 5 are detachable. If the cart is configured to be separable into a plurality, the reading efficiency may be improved. The cart may be placed on a traveling cart and passed through a gate (useful when the cart can be separated). Further, since the cart corresponds to one patient, the cart can be downsized as compared with a conventional surgical cart, which contributes to space saving. As described above, the cart also includes a tray for temporarily storing medical articles during picking.
[0022]
[Exclusive gate]
The gate 6 constitutes a gate type antenna provided with an antenna for reading information of the S-label. The gate 6 forms a gate-shaped passage portion from the left and right side walls 6a and 6b and the upper wall 6c, and a plurality of antennas 7 are arranged on the upper wall and the left and right side walls so as to face the passage portion. I have. The antenna 7 is electrically connected to a scanner 8 provided above the gate 6, and the scanner 8 is electrically connected to the computer 1. The signal received by the antenna 7 is read by the scanner 8, Data is sent to the computer 1. Many kinds of articles are loaded on the operation cart 2, and it is preferable to arrange a plurality of antennas in a portal shape in order to read them all at once. Note that the antenna 7 and the scanner 8 can also be called a tag reader or a reading device.
[0023]
[Identification of used items in surgery]
The cart card 4 and the patient card 5 can be detachably attached to the cart 2 (for example, a card insertion pocket is provided in the cart 2). Pass through 6. When the cart identification information of the cart card 4 matches the cart identification information of the patient card, it is determined that the cart 2 and the patient match, and the cart 2 is used based on the article card 3 without being used for surgery. The article card of the article left in is read. The used article can be specified by subtracting the article read after the operation from the loaded article (the loaded article master is prepared for each cart) held in correspondence with the cart card 4. Because the patient card is associated with a particular cart, reading the patient card simultaneously synchronizes the patient information with the item for use. For moving goods from specific shelves or other carts that are not synchronized with the cart name, the goods card of the used goods is removed from the goods and read by passing through a dedicated gate, and added as used goods. As described above, according to the system of the present invention, the articles used in the operation are displayed in a list along with the cart name, the patient name, and the like. You may make it display on a specification together with a disease name and a surgical procedure. When the cart identification information of the cart card 4 does not match the cart identification information of the patient card, it is determined that the cart 2 and the patient information are different, and the subsequent processing is not performed.
[0024]
[Replenishment of used goods]
The replenishment of the used articles of the cart loaded articles is performed according to a leaving instruction. For goods used from specific shelves or other carts, if the cart identification information (medical department, card number) indicating movement from another cart is written on the back of the used goods card, the cart identification will be included in the transfer instruction The information is manually transcribed, and other items are restocked on the shelf. Regarding the newly refilled cart, when the same article as the used article is refilled, the article card removed from the already used article is reused and attached. In addition, at the time of new registration (for example, article change, constant change), a cart card is issued by putting the cart name in the article master. The same applies to specific shelves, other carts, and newly replenished articles.
[0025]
[Overall flow]
Since the articles loaded on the cart are different for each medical department and are often common within the same medical department, the carts are preferably grouped for each medical department. Therefore, a plurality of carts each carrying a predetermined article are prepared for each medical department, and each cart is given a cart name. For example, a cart is identified by setting a medical department and a cart number as in Ophthalmology-1 and Ophthalmology-2. Then, a cart card is issued for each cart on which a predetermined article is loaded. The cart card is held in the holding section of the corresponding cart. An article card is attached to all the articles loaded in each cart.
[0026]
When a patient's department is input on the input screen on the computer when preparing a patient's scheduled operation, a cart is automatically selected and assigned (the cart number is selected using the department as a key). . When patient information such as a patient name is input, a patient card is issued. The patient card is held in the holding section of the cart.
[0027]
After the operation, a special cart is passed through a special gate. At this time, the computer reads the information on the article card loaded on the cart, the information on the cart card, and the information on the patient card. The product card reads information on the items left in the cart without being used, the cart card gives the product information originally loaded on the cart via the cart name, and the patient card gives the patient information. Is read. For goods used from specific shelves or other carts, the goods card attached to the goods is separately read at a dedicated gate, and the used goods are directly added. By processing these in the computing section of the computer, it is possible to obtain a patient use statement. Note that, even if an article loaded on another cart during the operation is used at the same time, after the operation, each cart is read through the dedicated gate as it is. In this case, the used article may not correspond to the actually used patient. For example, in Cart 1 (Patient A) and Cart 2 (Patient B), four articles were used in Cart 1 and two were used in Cart 2, but one article loaded in Cart 2 was used for Patient A. (Actually five were used for patient A and one for patient B). In this case, the replenishment of the articles in each cart may be performed as it is, but the content is corrected based on the transfer instruction when creating the patient use details.
[0028]
【The invention's effect】
As described above, according to the present invention, it is possible to manage information on articles used in surgery together with patient information by simple means. In particular, even when a large number of operations (for example, 30 to 40) are performed in a day, the cart returned after the operation is simply passed through the gate, so that the surgical article and the patient can be mistaken. Since it is possible to perform management without any omissions, even a part-time person who has no knowledge of surgery, surgical items, hospital systems, and the like can easily perform processing.
