  The element is formed of a semiconductor. If the element is housed in a dental member such as an artificial tooth in the oral cavity, a dental prosthesis, a denture base, or the like, and exposed to saliva or the like for a long time, harmful substances may be eluted.

The conventional information storage devices described in Patent Documents 1 to 3 do not take that point into consideration. In the personal data storage device described in Patent Document 1, it is described that the periphery of an element is filled with a heat insulating material. However, it is not clear whether even if the element is wrapped around the element with a heat insulating material, the element can be prevented from being eluted. Further, in the personal data storage device described in Patent Document 1, since the element wrapped in the heat insulating material is built in the hole of the crown prosthesis and covered with a relatively thin lid from the front side, harmful leakage from the heat insulating material is caused. Material may also leak out of the lid.
Therefore, the conventional information storage devices described in Patent Documents 1 to 3 are not suitable for long-term use.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an information storage device that allows a wearer to incorporate an information storage element in a dental material used in the oral cavity so that the wearer can live safely even when used for a long period of time.

  In the information storage device of the present invention, the concave portion of the dental member used in the wearer's oral cavity is filled with the filling resin material, and the information for identifying the wearer is electrically read by the information reading device. In a state in which the storage element is sealed with the sealing resin material, the filling element is disposed and embedded in the filling resin material, and the filling portion made of the filling resin material filled in the recess includes the information storage element. It is formed by a first filling portion to be embedded and a second filling portion serving as a lid of the first filling portion, and the first filling portion and the second filling portion are colored in different colors. To do.

According to the information storage device of the present invention, the information storage element is not only embedded in the filling portion formed of the filling resin material but also sealed by the sealing portion formed of the sealing resin material. Therefore, it is possible to prevent harmful substances that affect the human body from the information storage element from leaking out from the filling portion.
Since it is formed by the 1st filling part which embeds an information storage element, and the 2nd filling part used as the lid of the 1st filling part, the 2nd filling part used as a lid is hard, and the 1st filling part is the 2nd filling It is possible to make the properties of the filling resin material different by making them softer than the part or different colors.
And since the 1st filling part and the 2nd filling part are colored in a different color, when a dentist or a dental technician cuts the 2nd filling part, the 1st of a color different from the 2nd filling part When the artificial tooth is cut, it is possible to prevent the information storage element from being damaged or broken by mistake when the artificial tooth is cut because the filling part is exposed to realize that the second filling part has been deepened. .

  When the sealing portion made of the sealing resin material for sealing the information storage element is a coating layer formed on the surface of the information storage element by the sealing resin material, the sealing portion is formed thin. Therefore, the opening of the recess can be narrowed, and the depth of the recess can be reduced.

  When the sealing portion has the coating layer as the first sealing portion and the second sealing portion is further formed of a sealing resin material, the harmful substance from the information storage element is further filled with the resin material. It can be prevented from leaking out.

  When the second sealing portion is formed to be softer than the resin material for filling, the second sealing portion receives the pressure of meshing with the information storage element and relieves the pressure. The effect of pressure on can be reduced.

  When the peripheral wall of the concave portion rises from the bottom of the concave portion through a concave curved surface, the peripheral wall of the concave portion receives external pressure and the concave curved surface relaxes, thereby suppressing the occurrence of cracks in the filling portion. Can do.

  Since the present invention is sealed by the sealing portion formed of the sealing resin material, it is possible to prevent harmful substances that affect the human body from the information storage element from leaking from the filling portion. As a result, the wearer can safely live even if the wearer incorporates an information storage element in the dental material used in the oral cavity and uses it for a long time.

An information storage device according to Embodiment 1 of the present invention will be described with reference to the drawings. In the information storage device according to the first embodiment, a case where “information storage element” is stored in “artificial tooth” as an example of a dental member used in the oral cavity of the wearer will be described.
In the information storage device shown in FIG. 1, a filling portion 12 is formed by filling a recess 11 formed in the central portion of the artificial tooth 10 on the occlusal surface S side with a filling resin material. A storage element 13 is embedded.

As the artificial tooth 10, porcelain teeth, resin teeth, metal teeth, and the like can be used. The artificial teeth 10 can be 1 to 3 in the upper left, upper right, lower left and lower right. However, since the occlusal surface is wide and the concave portion 11 is easily formed in the central portion, the 4th to 7th respectively. Is desirable.
As shown in FIG. 2, the concave portion 11 has a cylindrical peripheral wall 11a rising from the bottom portion 11b via a concave curved surface 11c.

Dental resin can be used as the filling resin material forming the filling portion 12. For example, the dental resin can be an acrylic resin or a silicone resin. The filling portion 12 can be formed by dropping a filling resin material into the recess 11 by potting or injecting a filling resin material from an injector. The filling resin material may be the same color as the artificial tooth 10 or a different color. When the filling portion 12 (filling resin material) has the same color as that of the artificial tooth 10, the tooth in which the information storage element 13 is built cannot be distinguished from others, so that it can be made inconspicuous.
Further, if the filling resin material has a color different from that of the artificial tooth 10, the position of the filling portion 12 can be identified from the appearance, so that an operator who wants to read information electrically by the information reading device has a built-in information storage element 13. It is possible to identify the position of the formed tooth at a glance.

  The information storage element 13 can be a non-contact passive tag type RFID tag. The information storage element 13 stores identification information (ID information) for indirectly identifying an individual by being associated with personal information registered in the database. In addition, when the storage capacity of the information storage element 13 is sufficient, in addition to identification information for identifying an individual, the name, address, date of birth, sex, blood type, and the dental clinic involved in the treatment are identified. Personal information such as the name of the hospital to be operated and a code for identifying the hospital can be stored in the information storage element 13. Furthermore, when the storage capacity of the information storage element 13 is sufficient, it is possible to store a family history, a medical history, a medication history, a social history, a family history, and the like as a contact address. In particular, when the wearer suffers from dementia, if the information storage element 13 stores information about the family to be contacted, the identity of the wearer who is hesitant can be confirmed immediately, and the family can be contacted. You can get in touch and get in touch immediately when you get permission for the wearer's treatment. The information storage element 13 obtains an electromotive force by irradiating a radio wave from an information reading device (not shown), thereby transmitting various information stored in the information storage element 13 to the information reading device, and electrically reading the information. It is done.

  As shown in FIG. 3, the information storage element 13 is covered and sealed by a sealing portion 14 formed of a film layer such as a thin skin. As the sealing resin material forming the sealing portion 14, for example, paraxylylene resin that is safe for the human body can be used. By coating the information storage element 13 with this paraxylylene resin by chemical vapor deposition (CVD), a sealing portion 14 with a thin film layer of about 0.1 μm to 50 μm is formed in close contact with the information storage element 13. can do. Moreover, the sealing part 14 can also be made into thickness of 50 micrometers or more as needed.

In the information storage device according to Embodiment 1 of the present invention configured as described above, the information storage element 13 is not only embedded in the filling portion 12 formed of the filling resin material, but also for sealing. It is sealed by a sealing portion 14 formed of a resin material. Therefore, it is possible to prevent harmful substances that affect the human body from the information storage element 13 from leaking out from the filling portion 12.
Therefore, the information storage device allows the wearer to live with peace of mind even if the wearer incorporates the information storage element 13 in the dental material used in the oral cavity and uses it for a long time.

  Moreover, since the sealing part 14 is formed of a coating layer, the thickness of the sealing part 14 can be reduced, so that the opening of the recess 11 can be narrowed and the depth of the recess 11 can be reduced. Can do.

  Further, even when pressure is applied to the concave portion 11 by meshing with the tooth that mates with the artificial tooth 10, the peripheral wall 11a of the concave portion 11 rises from the bottom portion 11b via the concave curved surface 11c. Since the concave curved surface 11c relieves pressure, the occurrence of cracks in the filling portion 12 can be suppressed.

(Embodiment 2)
An information storage apparatus according to Embodiment 2 of the present invention will be described with reference to the drawings. In the information storage device according to the second embodiment, as shown in FIGS. 4 and 5, the sealing portion for sealing the information storage element 13 is formed from the first sealing portion 14 a and the second sealing portion 14 b. It is characterized by being. 4 and 5, the same components as those in FIGS. 2 and 3 are denoted by the same reference numerals, and description thereof is omitted.

The first sealing portion 14a is the sealing portion 14 (see FIG. 3) of the information storage device according to the first embodiment. The information storage element 13 covered with the first sealing portion 14a formed by the coating layer is further sealed with an oval second sealing portion 14b.
As described above, since the information storage element 13 is sealed not only by the first sealing portion 14a but also by the second sealing portion 14b, further harmful substances from the information storage element 13 leak from the filling portion 12. It can be prevented from exiting.

  The second sealing portion 14b is made of a softer resin material than the filling portion 12 made of a filling resin material. Therefore, even if the pressure is applied to the concave portion 11 due to the meshing with the tooth that mates with the artificial tooth 10, and the filling portion 12 receives this pressure, the second sealing portion 14b receives the pressure on the information storage element 13. Therefore, the influence of pressure on the information storage element 13 can be reduced.

(Embodiment 3)
An information storage apparatus according to Embodiment 3 of the present invention will be described with reference to the drawings.

Since the filling portion is divided into the first filling portion 12a and the second filling portion 12b, the properties of the filling resin material can be made different.
For example, the second filling portion 12b serving as a lid is hard so that even when meshing with the mating teeth, the first filling portion 12a is the second filling in order to reduce the impact on the information storage element 13. It can be made softer than the part 12b.

  Further, the first filling portion 12a and the second filling portion 12b can be different colors. By using different colors for the first filling portion 12a and the second filling portion 12b, when the dentist or dental technician cuts the artificial tooth 10 from the occlusal surface S, the second filling portion 12b has a different color. When the first filling portion 12a is exposed, it is noticed that the second filling portion 12b has been deepened too much. Therefore, it is possible to prevent the information storage element 13 from being damaged or broken by mistake when the dentist or dental technician cuts the artificial tooth 10.

The 2nd filling part 12b can be made into the same color as the artificial tooth 10, or a different color. If the second filling portion 12b (filling resin material) has the same color as that of the artificial tooth 10, the tooth in which the information storage element 13 is built cannot be distinguished from others, and thus it can be made inconspicuous.
Further, if the second filling portion 12b has a color different from that of the artificial tooth 10, the position of the second filling portion 12b can be identified from the appearance. The position of the tooth with built-in 13 can be identified at a glance.

  As described above, since the filling portion in which the information storage element 13 is embedded is covered not only with the first filling portion 12a but also with the second filling portion 12b, the harmful substances from the information storage element 13 are further reduced. 2 It is possible to prevent leakage from the filling portion 12b.
