Description

  The present invention relates to a phototherapy device.

  The phototherapy device has been used for treatment of pain relief, for example, by irradiating percutaneously with an infrared ray (approximately 700 nm to 2500 nm) as treatment light, aiming at an affected area or acupoint. In recent years, irradiation with light has revealed effects on various nerves such as selective suppression of nerve transmission of sensory fibers that convey pain in the peripheral nervous system, suppression of pain-inducing substances, and relaxation of sympathetic nerve tension. Applying these effects, improvement treatment of urination disorder has also been made by light irradiation (Patent Document 1). Among the light beams, laser light is widely used in these applications because it can irradiate a specific wavelength with high output. In such treatment, since the same site such as an affected part or acupoint is repeatedly irradiated, it is necessary to identify the treatment site immediately. Therefore, for example, Patent Document 2 proposes a configuration including a pad provided with an adhesive sheet on the back surface and a probe provided with a touch sensor that operates in contact with the pad in the vicinity of the laser emission port. Yes. According to this configuration, by attaching the pad to the affected area, the irradiation position can be easily identified by the doctor or patient by visually recognizing the pad, and the same part can be repeatedly irradiated.

JP 2009-172068 A Japanese Patent Laid-Open No. 11-137698

  However, in the case where phototherapy is performed using the phototherapy device of Patent Document 2 above, in the case where the treatment site is on the back of the patient and light irradiation must be performed by the patient himself (for example, irradiation at home) Since it is difficult to visually recognize the pad, it is difficult to accurately specify the irradiation position. Moreover, it has the subject that it always becomes painful for a patient to hold | maintain a probe to a back part. For example, in the treatment of urination disorder by light irradiation, light is percutaneously irradiated aiming at the vicinity of the sacral hole where the bladder sensory nerve is present in order to suppress abnormal activity of the sensory nerve of the bladder. For appropriate treatment, it is necessary to repeat light irradiation for several minutes to several tens of minutes a day twice a week to every day, so that it is desirable for the patient to perform light irradiation at home. The sacral foramen is located under the lumbar region under the skin, and it is in the back where the patient cannot see even if a mark such as a pad is placed on the skin above it, so it is difficult to accurately align the probe directly above the sacral foramen . In addition, if the patient keeps the irradiation probe on the back while holding the irradiation probe on the back, the patient is forced to become unreasonable. For this reason, it is not possible to perform light irradiation accurately aiming at the sacral hole, making it difficult to perform appropriate treatment.

  Therefore, the present invention provides accurate treatment of the sacral foramen even when the treatment site is not visible on the back of the patient, such as light irradiation for patients with dysuria, and the patient himself irradiates light at home or the like. An object of the present invention is to provide a phototherapy device capable of performing targeted light irradiation and, as a result, realizing appropriate treatment.

  In order to achieve this object, a phototherapy device of the present invention includes a light source, a housing surrounding the light source, an optical window that transmits light formed in a part of the housing, and a housing formed in a part of the housing. A side fitting portion, an adhesive sheet for attaching to the skin, a transmission window formed in a part on the adhesive sheet, and a convex sheet side fitting portion formed on the adhesive sheet. The housing is fixed on the adhesive sheet in a state where the transmission window and the optical window are at least partially overlapped by fitting the housing side fitting portion and the sheet side fitting portion. A treatment device was obtained.

  According to this configuration, even if the treatment site is in a position where it cannot be visually recognized on the back of the patient and the patient himself irradiates light at home etc., the convex shape formed on the adhesive sheet affixed to the skin By touching the seat-side fitting portion, the treatment site can be identified without visual recognition. At the same time, the light source can be fixed on the seat by the housing side fitting portion and the seat side fitting portion, so that the irradiation position can be accurately irradiated without being held by the patient.

(Hard structure of the first embodiment)
Hereinafter, a phototherapy device according to an embodiment of the present invention will be described with reference to the accompanying drawings. The phototherapy device of this embodiment is a device for treating dysuria by irradiating a patient with a light beam at the position of the sacral hole.

  FIG. 1 is a perspective view of a phototherapy device according to the present embodiment. The phototherapy device includes an irradiation probe 1 and a probe fixing sheet 2.

  The irradiation probe 1 is a member that is fixed to the probe fixing sheet 2 and irradiates a predetermined irradiation site on the patient's skin with light. The irradiation probe 1 includes a housing 3. The housing 3 is made of, for example, plastic or metal and has a hollow cylindrical shape. The shape of the housing 3 does not have to be cylindrical, and can be selected as appropriate, such as a rectangular parallelepiped shape or a hemispherical shape.

  The irradiation probe 1 also includes a housing side fitting portion 4. The housing-side fitting portion 4 is a fitting extending from the outer peripheral surface of the housing 3 in the radial direction to the fitting portion upper wall 5 and the fitting portion upper wall 5 from the outer diameter side end portion downward (toward the patient's skin). A partial side wall 6 is provided. In FIG. 1, the housing-side fitting portion 4 is formed over the entire circumference of the housing 3, but the housing-side fitting portion 4 only needs to be formed in a part of the circumferential direction of the housing 3.

  A light source 7 is installed inside the upper surface of the housing 3 (the bottom surface of the cylinder opposite to the patient's skin). As the light source 7, a laser, LED, halogen lamp, xenon lamp, or the like can be used. The light source 7 is connected to a power source and a switch (not shown) installed outside the housing 3, and irradiates the patient with light by switching the switch. The light source 7 may be guided into the housing 3 from the outside of the housing 3 through a light guide such as an optical fiber.

  The probe fixing sheet 2 is a member that is attached to the patient's skin (in this embodiment, the skin on the sacral hole of the patient) in order to fix the irradiation probe 1 on the patient's skin. The probe fixing sheet 2 includes a flexible adhesive sheet 8 made of, for example, a polyurethane film. An adhesive layer 9 made of a silicone-based adhesive is provided on the skin side surface of the adhesive sheet 8. Since the adhesive layer 9 has adhesiveness, the adhesive sheet 8 can be attached to the skin. The pressure-sensitive adhesive layer 9 only needs to be able to affix the pressure-sensitive adhesive sheet 8 to the skin, and the material can be appropriately selected in addition to the silicone-based pressure-sensitive adhesive. Further, when the adhesive sheet 8 itself is formed of a material having adhesiveness such as a silicone gel that can be directly attached to the skin, the adhesive layer 9 may not be used.

  In order to irradiate the skin with light emitted from the light source 7, a transmission window 10 is formed in the substantially central part of the adhesive sheet 8 and the adhesive layer 9. In the present embodiment, the transmission window 10 is a hole provided in the adhesive sheet 8. However, the transmission window 10 only needs to be able to transmit the irradiation light, and part of the adhesive sheet 8 and the adhesive layer 9 may be formed of a material that transmits light, such as a plastic film.

  Around the transmission window 10 on the surface of the adhesive sheet 8 on the light source 7 side (surface opposite to the patient's skin), a plurality of convex sheet-side fitting portions 11 are formed. In the present embodiment, the seat side fitting portion 11 is an annular shape defined by the outer peripheral surface of the housing 3, the fitting portion upper wall 5, and the fitting portion side wall 6 so as to be fitted to the housing side fitting portion 4. A plurality of columns are formed along the space. Moreover, since the seat side fitting part 11 is formed in convex shape, even if a patient does not visually recognize, the position where the sheet | seat is stuck can be pinpointed by touching the sheet side fitting part 11. FIG. In addition, since the seat-side fitting portion 11 is configured by a plurality of independent convex shapes, it is possible to suppress deterioration without collecting dirt and water inside the convex shape during bathing or the like. In addition, the sheet | seat side fitting part 11 may be formed in one convex shape. In this case, by providing a notch in a part of the convex shape, it is possible to suppress deterioration without collecting dirt and water inside the convex shape during bathing or the like. The seat side fitting part 11 positions and fixes the housing 3 with respect to the patient without being held by the patient itself by fitting and fixing to the housing side fitting part 4 by a method described later.

  FIG. 2 is a schematic diagram showing a cross-sectional view of the present treatment shooting apparatus in a state where the housing side fitting part 4 and the sheet side fitting part 11 are fitted when the probe fixing sheet 2 is affixed on the patient's skin. .

  An optical window 12 for transmitting light from the light source 7 is formed on the lower surface of the housing 3 (the cylindrical bottom surface on the patient's skin side). The optical window 12 is formed to have a smaller diameter than the transmission window 10 at a position that approximately matches the transmission window 10 on the adhesive sheet 8 when the sheet side fitting portion 11 and the housing side fitting portion 4 are fitted. The That is, in order for the light emitted from the light source 7 to reach the skin 13 of the patient, the optical window 12 and the transmission window when the seat side fitting portion 11 and the housing side fitting portion 4 are fitted. The housing 3 is formed so as to be fixed on the adhesive sheet 8 in a state where at least a part of 10 overlaps. In the present embodiment, the optical window 12 is a hole formed in the housing 3. In order to protect the light source 7, the optical window 12 may be formed by forming a part of the lower surface of the housing 3 with a material such as glass or plastic through which the irradiation light is transmitted. The irradiation light irradiated from the light source 7 in the state shown in FIG. 2 passes through the optical window 12 and the transmission window 10 and is irradiated onto the skin 13 of the patient.

  FIG. 3 is a schematic diagram showing an embodiment of the housing side fitting portion 4 and the seat side fitting portion 11. In the present embodiment, the housing side fitting portion 4 is formed of a permanent magnet, and the sheet side fitting portion 11 is formed of a magnetic material. The housing-side fitting portion 4 is not limited to being entirely formed of a permanent magnet, and a permanent magnet may be incorporated in a part of the housing-side fitting portion 4. Further, the sheet-side fitting portion 11 is not limited to the entirety formed of a magnetic material, and a magnetic material may be incorporated in a part of the sheet-side fitting portion 11. Contrary to the above configuration, the seat side fitting portion 11 may include a permanent magnet, and the housing side fitting portion 4 may include a magnetic body. Moreover, the housing side fitting part and the sheet side fitting part 11 may each include a permanent magnet having a reverse polarity. Thereby, even if the patient does not hold down the housing side fitting part 4 by hand, it can be easily fixed to the seat side fitting part 11 by magnetic force.
