Description

  The present invention relates to an optical memory card configured to record personal information such as medical information in an accumulative manner and to view the record on a personal computer as necessary.

  Medical information when a patient is examined in a hospital or the like includes a wide range of information such as analysis of life phenomena in addition to medical information, patient information, and hospital information. The hospital information is information related to medical affairs, examinations, drugs, and meals.

  The typical medical information is medical chart information, but in the conventional medical chart, even if blood pressure values for 10 years are listed for each examination, in many cases doctors rarely tabulate blood pressure values. , Even if you try to know the progress of blood pressure over 10 years, you can not know easily, you can not see in the graph. In addition, it is not easy to see the drugs described in the medical chart over time.

  On the other hand, computers have been introduced into hospitals because they have features such as ease of handling the amount of information, speed of search, and accuracy. However, individual patient data can be used quickly only by the hospital. Even if it can, it is almost impossible to transfer to other hospitals, and there is no database compatibility.

  In this way, even if a computer is introduced into a hospital, the database is not sufficiently utilized, which can be said to be the biggest drawback in medicine. When data is obtained by analyzing the blood of the instructed patient in the hospital database, the patient ID number, patient name, gender, doctor name, laboratory name, laboratory technician name, GOT are stored in the computer storage device. Values, GPT values, LDH values, cholesterol values, triglyceride values, blood glucose levels, etc. are recorded.

  Looking at the hospital database, the medical database, examination database, etc. can be used in that field, and within that hospital, for example, doctors in the department can retrieve their patient data from the examination database. it can. However, since there is no database compatibility at present, it is impossible to send patient data of hospital A to hospital B.

  Another disadvantage of the medical database is that there is no individual patient database. If this is done, the patient's name, registration number, date of birth, sex, examination for each visit date, drugs, X-rays, and all other information that occurred in the hospital will be recorded. For example, all information after the first visit of the patient can be obtained immediately. However, if there is no such database, it will be time consuming because the examination must be searched in the examination database and the drug in the medicine database. Personal databases are thus convenient and highly effective for medical support, but there are few hospitals equipped with them at present.

Under such circumstances, for example, Patent Document 1 provides a medical portable recording medium capable of accumulating and recording personal information. This conventional medical portable recording medium comprises a DVD-RAM portion made of a rectangular card suitable for carrying. This conventional rectangular card is formed by laminating single or plural synthetic resins in order to obtain appropriate rigidity and elasticity.

  It can be applied only to a conventional medical portable recording medium DVD-RAM and cannot be additionally written. In addition, the vertical and horizontal sizes of the medium are specified, which is not sufficient for large-capacity recording. In addition, it is necessary to have a size that can be put in a wallet card for convenience of carrying, but it is not such a size. Furthermore, the thickness of the card is 0.6 mm or more and a laminated structure of two or more reinforced plastics. For this reason, it is inflexible and the card may be damaged while being carried.

  The present invention relates to a rectangular substrate having a thickness of 0.6 mm, an optical disc information recording layer that can be recorded / reproduced on the substrate, and a thickness of 0 bonded to the rectangular substrate with the optical disc information recording layer interposed therebetween. There is provided an optical memory card comprising a laminated structure card composed of a 0.2 mm rectangular auxiliary substrate, wherein the outer diameter of the recordable / reproducible optical disc layer corresponds to the card width size.

  When the present invention is applied to a portable medical recording medium, a wide range of information such as analysis of life phenomena can be accumulated and carried for decades in addition to personal medical information, patient information, and hospital information. This data can be used not only at one hospital but also at other hospitals, enabling accurate diagnosis.

  Hereinafter, an optical memory card according to an embodiment of the present invention will be described with reference to the drawings.

  1 and 2 show an optical memory card according to an embodiment of the present invention, for example, a write-once optical memory card used in a medical information system, such as a CD-R optical disc, a DVD ± R optical disc, or a DVD ± RW optical disc. A write-once optical memory card 11 is shown. The write once optical memory card 11 includes a rectangular substrate 12 having a thickness of 0.6 mm, a recordable / reproducible optical disc information recording layer 13 formed on the substrate 12, and a rectangular substrate sandwiching the optical disc information recording layer 13. 12 is formed of a laminated structure card 15 formed of a rectangular auxiliary substrate 14 having a thickness of 0.2 mm joined to 12. A hole 17 is formed in the center of the laminated structure card 15.

  Further, a scratch preventing film 16 is applied to the surface of the rectangular substrate 12 which is not the bonding surface with the rectangular auxiliary substrate 14 of the laminated structure card 15 and serves as the laser light input / output surface. The substrate 12 and the auxiliary substrate 14 are formed of a plastic such as polycarbonate, and the scratch preventing film 16 is formed of a thin film having a thickness of about 1 μm. The information recording layer 13 is composed of a thin organic film having a thickness of about 1 μm or a non-organic film having a thickness of several tens of nanometers and a reflective film having a thickness of 0.1 μm or less formed of gold or aluminum. Is done. The optical disk information recording layer 13 and the rectangular substrate 12 are connected by an adhesive having a thickness of about 1 μm or several tens of nanometers.

  The size of the laminated structure card 15 is preferably about 85 mm in length L and 62 mm or less in width so that it can enter a wallet such as a wallet. The outer diameter of the optical disc information recording layer 13 corresponds to the width W of the card 15. A part of the recording layer 13 of the card 11, for example, the innermost peripheral part is assigned as a read-only recording layer, that is, a ROM, and the remaining part is a write-once storage area. The recording layer can be composed of a ROM layer having a thickness of about 100 nanometers and a RAM layer having a thickness of about several tens of nanometers.

  In the optical memory card of this embodiment, when the diameter of the optical disc information recording layer 13 is 61 mm, a storage capacity of about 300 megabytes (MB) can be obtained. However, unlike CD, in DVD, the innermost part of the disc recognizes the disc type, that is, DVD-RAM, DVD-R, DVD-RW, DVD-ROM, DVD + R, DVD + RW, or a combination thereof. There is a considerable portion, and the area from the innermost circumference to several millimeters cannot be used for recording information by the user. Therefore, in order to increase the capacity that can be recorded by the user, it is inevitably necessary to increase the outer diameter, and if necessary, it is important to overlap the recording layers from double to maximum four. FIG. 4 shows a four-layer recording layer 13.

  Current optical disk head light sources are centered on a red wavelength of 650 nm, one centered on a purple-blue wavelength of 405 nm, and further centered on an infrared wavelength of 780 nm used in past CD systems. There is a system. However, the focal depth in the plastic substrate of the lens is about 1 μm even in the case of a so-called HD DVD that is centered on a purple-blue wavelength of 405 nm and the numerical aperture of the objective lens of the optical head of the optical disk drive is about 0.65. Therefore, even if the recording layer has a double, triple, and maximum quadruple structure, each layer can be easily focused if the layers are about 20 to 30 μm. As a result, if the width is 56 mm, if it is 150 MB, 216 MB is possible at the width of 61 mm, and if the NA of the objective lens is 0.65, and 595 MB is obtained when the wavelength is 405 nm. It becomes possible. On the other hand, when the recording medium is formed of a double layer, the recording capacity is 1 GB or more. A storage capacity of 1.5 GB is obtained for the triple recording layer and 2 GB for the quadruple recording layer.

  Current optical disk drives include a spring-fixed type and an automatic mounting type of a stationary personal computer that are used in notebook personal computers as a method for fixing and rotating an optical disk. Particularly in the latter case, the disk does not operate unless the disk thickness is at least 0.8 mm. Therefore, there is a problem that the automatic mounting method cannot be used in the existing method (disk thickness is 0.6 mm). However, in this embodiment, since the total thickness of the substrate 12 and the auxiliary substrate 14 is 0.8 mm, it can be used for an automatic mounting type personal computer.

  In the write-once optical memory card 11 as described above, the patient name, registration number, date of birth, sex, examination for each visit date, drugs, X-rays, and other information generated in the hospital are recorded. Furthermore, information such as patient ID number, patient name, gender, doctor name, laboratory name, laboratory technician name, GOT value, GPT value, LDH value, cholesterol value, triglyceride value, blood glucose level is stored. The

The recording / reproducing disc 15 has a disk shape with a diameter of 85 mm in the longitudinal direction, and the horizontal direction is symmetrical with respect to a hole 17 having a diameter of 15 mm at the center, and the disc is parallel with parallel lines. An optical memory card having a cut width of 62 mm or less is shown.

  In FIG. 6, a semiconductor chip 18 is embedded in a peripheral area 19 of a laminated structure card 15 having no recording layer, and a conductive wire capable of transmitting and receiving electromagnetic waves on the inner circumference of the laminated structure card is provided on the outer circumference of the recording layer. The optical memory card installed in is shown. The semiconductor chip may be provided in the inner region 20 of the recording layer 13.

  FIG. 7 shows a state where the optical memory card of the present invention is mounted on a personal computer. Information can be written to and read from the optical memory card by loading the optical memory card in the DVD drive of the personal computer as shown in this figure.
