Description

  The present invention relates to a power supply unit for iontophoresis in which drug ions are administered to a living body by applying a voltage.

  In iontophoresis, drug ions are administered to the skin and mucous membrane of a living body, and the iontophoresis device is preferably flexible so that it can bend in accordance with the shape of the surface of the living body. The iontophoresis device is preferably lightweight in order to reduce the burden on the living body.

  In response to such needs, iontophoresis devices are known in which a chemical solution or the like is applied in a gel state, or impregnated with gauze or the like and formed into a thin film shape, which is a flexible sheet as a whole.

  In addition, as a power supply unit connected to the iontophoresis device, one that converts alternating current into direct current and outputs it to the iontophoresis device, or one that includes a battery is known.

  If a power supply unit including a battery is used, drug ions can be administered even in a place where there is no external power supply, and it is easy to carry because it is small compared to a power supply unit that converts alternating current into direct current. If such a power supply unit and iontophoresis device are accommodated and carried, for example, in a bag-shaped packaging material, it is possible to administer drug ions with almost no restrictions on location and time, which is convenient. For example, if a power supply unit and an iontophoresis device are accommodated in an aluminum bag-shaped packaging material and nitrogen gas or the like is enclosed therein, long-term storage is possible.

  In addition, even when administering drug ions, a power supply unit equipped with a battery can be attached to a living body together with an iontophoresis device, so that it is possible to receive drug ions without restricting behavior. There is.

  In order to be used for such applications, the power supply unit is also preferably small and light. For example, if a structure in which a power supply unit including a battery and an iontophoresis device are combined together is considered to contribute to reduction in size and weight (for example, see Patent Documents 1 and 2).

  However, such a structure in which the power supply unit and the iontophoresis device are combined together is likely to have high rigidity as a whole, and the iontophoresis device is difficult to bend following the shape of the surface of the living body.

  On the other hand, a power supply unit that is separate from the iontophoresis device and is used by being connected to the iontophoresis device with a conductive wire is known (for example, see Patent Document 3).

  As a structure for reducing the size and weight of a power supply unit that is separate from such an iontophoresis device, for example, a structure in which a battery, an electronic component, etc. are exposed on a substrate can be considered.

JP 2000-219623 A JP 2004-188188 A JP 2000-300682 A

  However, if the battery, the electronic component, etc. are exposed, there is a concern that the finger, etc. may be damaged due to erroneous contact with the battery, the electronic component, etc.

  Further, if the battery, the electronic component, the wiring of the substrate, etc. are exposed, there is a possibility that improper energization may occur due to the moisture, aluminum packaging material, etc. coming into contact with the battery, the electronic component, the wiring or the like.

  For example, if the power supply unit is housed in a resin or metal hard case having sufficient rigidity, these problems can be solved.

  However, when the power supply unit is accommodated in such a hard case, the effect of reducing the size and weight of the power supply unit and the iontophoresis device is diminished.

  In addition, since the power supply unit is removed from the hard case during use, the power supply unit may be damaged due to accidental contact of a finger or the like with a battery or electronic component during administration of drug ions, or the battery, electronic component, wiring, etc. Improper energization may occur due to contact with moisture.

  Furthermore, there is a problem that the cost increases by providing such a hard case.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a highly reliable iontophoresis power supply unit that is small in size and light in weight and that is not easily damaged or inappropriately energized. .

  Embodiments of the present invention include a battery, a connector connected to the battery, a substrate that supports the battery and the connector, and a resin sheet material that fits on the outer periphery of the substrate. The above object is achieved by an iontophoresis power supply unit that includes a cover member that constitutes a housing that accommodates the connector and that has a connector opening for connecting the connector to the mating connector.

  In this iontophoresis power supply unit, the battery and the connector are protected by the cover member, so that damage and inappropriate energization are unlikely to occur.

  Further, since the connector opening is formed in the cover member, the cover member can be connected to the iontophoresis device with the cover member attached. Therefore, the battery and the connector are protected by the cover member even during administration of the drug ion, and damage or inappropriate energization is unlikely to occur.

  Moreover, since the material of the cover member is a resin sheet material, it contributes to reduction in size and weight.

  The cover member has a shape that constitutes a housing that accommodates the substrate and the like so as to be fitted to the outer periphery of the substrate. Therefore, although the material is a resin sheet material, the cover member has a practically sufficient rigidity against contact with a finger or the like. Can be secured.

  The iontophoresis power supply unit 10 includes electronic components 24A, 24B, 24C, and 24D.

  As the battery 12, for example, a button battery or a thin battery disclosed in JP-A-11-067236, US Patent Publication No. 2004 / 0185667A1, US Pat. No. 6,855,441, or the like can be used.

  A part of the connector 14 protrudes from the connector opening 20 </ b> A of the cover member 20, and is coupled to the mating connector 18 outside the cover member 20. The mating connector 18 is attached to one end of a conductive wire 26, and the other end of the conductive wire 26 is connected to an iontophoresis device 28. The connector 14 has a male housing portion, and the mating connector 18 has a female housing portion.

  The iontophoresis device 28 is impregnated with a chemical solution or the like in gel, gauze or the like and formed into a thin film shape, and has a flexible sheet shape as a whole. It should be noted that the configuration of the iontophoresis device 28 is not considered important for understanding the embodiment of the present invention, and thus the detailed configuration of the iontophoresis device 28 will not be described.

  The substrate 16 is obtained by printing predetermined wiring such as copper foil on an insulating thin plate such as epoxy resin. In the first embodiment, the substrate 16 is substantially rectangular. However, the shape of the substrate 16 may be other shapes such as a circle according to the application.

  The cover member 20 has a structure in which a substantially rectangular parallelepiped box portion 21A whose one surface is open and a base portion 21B that is substantially larger than the opening portion of the box portion 21A and closes the opening portion are bonded or fused. A housing that accommodates the substrate 16, the battery 12, and the connector 14 is configured. The box portion 21A has a small flange portion formed on the outer periphery of the side wall of the opening, and is bonded or fused to the base portion 21B at the small flange portion.

  The connector opening 20A is formed on the side wall of the box portion 21A.

  As shown in FIG. 3, a switch member opening 20B through which the switch member 22 passes is formed on the other side wall of the box portion 21A.

Further, the small flange portion of the box portion 21 </ b> A and the portion outside the side wall of the box portion 21 </ b> A in the base portion 21 </ b> B constitute a flange portion 20 </ b> C of the cover member 20. Flange portion 20C is in contact with or close to one side of the retained portion 22A of the switch member 22 in the vicinity of the outside of the switch member opening 20B.

In a portion opposed to the retained portion 22A of the switch member 22 in the flange portion 20C as shown in FIG. 4 is a gripped portion 22A of the switch member 22 is formed with a cutout 20D for gripping with fingers.

  Further, a notch 20E for coupling the mating connector 18 to the connector 14 is formed at a portion of the flange portion 20C facing the connector 14.

  As a material for the cover member 20, a resin sheet material such as PET (polyethylene terephthalate) can be used. The cover member 20 is preferably colored so that the inside cannot be seen. As a method for forming the box portion 21A and the base portion 21B constituting the cover member 20, a known forming method such as a vacuum forming method can be used. The base 21B may be manufactured by cutting a flat sheet material into a desired shape with a press.

  The cover member 20 has antistatic properties. Examples of a method for imparting antistatic properties to the cover member 20 include a method in which a surfactant is mixed with a raw material polymer of the cover member 20 and a method in which the surface of the cover member 20 is coated with an ion conductive antistatic agent. Can do. Also, a method of covering the surface of the cover member 20 with a hydrophilic polymer or the like, a method of hydrophilizing the raw material polymer of the cover member 20 by copolymerizing or graft polymerization of a hydrophilic monomer, and covering a hydrophilic substance or hydrophilic polymer Examples of the method include mixing with the raw material polymer of the member 20. Furthermore, the method of coat | covering the surface of the cover member 20 with a metal thin film or conductive resin can also be mentioned. In addition, when performing the antistatic process on the surface of the cover member 20, it is preferable that the antistatic process is performed on the outer surface of the cover member 20, and the inner surface of the cover member 20 is insulative.

The gripped portion 22 </ b> A of the switch member 22 protrudes outside the side wall of the box portion 21 </ b> A of the cover member 20. When the switch member 22 is gripped and pulled by a finger or the like in the gripped portion 22A, the switch member 22 is inserted through the switch member opening 20B of the cover member 20 and removed from between the battery 12 and the substrate 16. ing. As a material of the switch member 22, for example, an insulating resin such as PET can be used. The iontophoresis power supply unit 10 is configured such that the wiring of the substrate 16 and the battery 12 are electrically connected by removing the switch member 22 from between the battery 12 and the substrate 16.

  The electronic components 24A, 24B, 24C, and 24D are resistors or the like and constitute a predetermined electric circuit. Note that the configuration of the electric circuit is not considered important for understanding the embodiment of the present invention, and thus the detailed configuration of the electric circuit is not described.

  The iontophoresis power supply unit 10 is packaged in a bag-shaped packaging material 30 as shown in FIG. 5, for example. Similarly, the iontophoresis device 28 is also packaged in a bag-shaped packaging material 31. As a material of the packaging materials 30 and 31, for example, an aluminum sheet can be used. Note that nitrogen gas or the like may be enclosed in the packaging materials 30 and 31.

  Next, effects of the first embodiment will be described.

  In the iontophoresis power supply unit 10 according to the first embodiment, the battery 12, the connector 14, and the electronic components 24A, 24B, 24C, and 24D are protected by the cover member 20. Is unlikely to occur.

  Furthermore, since the connector opening 20A is formed in the cover member 20, the cover member 20 can be connected to the iontophoresis device 28 with the cover member 20 attached. Therefore, the battery 12 and the connector 14 are protected by the cover member 20 even during administration of drug ions, and damage and inappropriate energization are unlikely to occur.

  Moreover, since the material of the cover member 20 is a resin sheet material, it contributes to reduction in size and weight. Thus, for example, even when the iontophoresis power supply unit 10 is fixed or placed on the iontophoresis device 28 when the iontophoresis device 28 is used, the weight of the iontophoresis power supply unit 10 is not reduced. It is possible to prevent or suppress the drop of the iontophoresis power supply unit 10 from the iontophoresis device 28 and poor contact due to the above.

  Since the cover member 20 has a shape that constitutes a housing that accommodates the substrate 16 and the like so as to be fitted to the outer periphery of the substrate 16, the cover member 20 is practically resistant to contact with a finger or the like while the material is a resin sheet material. Sufficient rigidity can be secured.

  Furthermore, since the cover member 20 has the flange portion 20C, the rigidity is enhanced also in this respect.

  The cover member 20 is a low cost because the material is a resin sheet.

  Further, since the cover member 20 has antistatic properties, generation of static electricity is prevented, and adhesion of dust and the like is suppressed.

The switch member 22 is a low-cost with a simple structure of the sheet, and, in contact with one surface of the retained portion 22A of the switch member 22 the flange portion 20C of the cover member 20 is in the vicinity of the outside of the switch member opening 20B Alternatively, since they are close to each other, the switch member 22 is protected from being accidentally removed.

  The gripped portion 22A of the switch member 22 protrudes outside the side wall of the box portion 21A of the cover member 20, and a notch 20D is formed in the flange portion 20C near the outside of the switch member opening 20B. Therefore, the gripped portion 22A of the switch member 22 can be easily gripped with a finger.

(Second embodiment)
Next, a second embodiment of the present invention will be described.

  As shown in FIG. 6, the second embodiment is different from the first embodiment in that a housing portion is provided on the iontophoresis power supply unit 10 side instead of the connector 14 having a male housing portion. The female connector 50 is provided, and a mating connector 52 whose housing portion is male is provided on the iontophoresis device 28 side instead of the female connector 18 whose housing portion is female.

  The position of the end face of the connector 50 substantially coincides with the outer periphery of the substrate 16 and does not protrude from the connector opening 20A.

  In the second embodiment, since the connector 50 is accommodated in the cover member 20 without protruding from the side wall of the box portion 21A of the cover member 20, iontophoresis caused by a finger or the like being in contact with the connector 50 by mistake. It is possible to further suppress damage to the power supply unit 10 for use and contribute to further miniaturization of the power supply unit 10 for iontophoresis.

  In the first and second embodiments, the notch 20D is formed in the flange portion 20C of the cover member 20, but this notch may be omitted. Since the switch member 22 has a sheet shape, even when there is no such notch, the gripped portion 22A can be gripped with a finger by warping the switch member 22 in a direction in which the gripped portion 22A is separated from the substrate 16. Is possible.
