Description

  The present application relates to an adapter set for an output measuring device including a package.

  Various medical devices are used in the medical field. For example, a laser treatment apparatus that irradiates an affected area with light such as laser light is known. The laser therapy apparatus is used, for example, for photodynamic therapy (hereinafter abbreviated as “PDT”). PDT is a local treatment method that utilizes a photochemical reaction caused by laser light irradiation on a photosensitive substance that accumulates in a large amount in cancer cells. A laser treatment apparatus that performs PDT includes a laser treatment apparatus main body that emits laser light, and an optical probe that includes an optical fiber. The optical probe transmits light to the affected area. Light (here, laser light) emitted from the laser treatment apparatus main body propagates through the optical fiber to reach the affected area as an irradiation target (see, for example, Patent Document 1).

  When using a device that emits light such as laser light, calibration may be performed before actually performing treatment (see, for example, Patent Document 2). Specifically, it is confirmed whether the output is an appropriate value by measuring the intensity of light emitted from the optical probe. When performing the calibration, the optical fiber is temporarily connected to the output measuring device so that the light from the optical fiber enters the output sensor of the output measuring device.

JP 2000-189527 A JP 05-115491 A

  After the calibration is completed, the optical fiber is separated from the output measuring device and used for the treatment. Therefore, it is advantageous that the tip of the optical fiber can be easily connected to and disconnected from the output measuring device from the viewpoint of promptly performing the treatment.

  As described above, when the calibration is performed, the light emitted from the optical fiber is incident on the output measuring device that measures the intensity of light. At that time, an adapter for holding the optical fiber may be connected to the output measuring device. The optical fiber is held by inserting the optical fiber into the adapter. Hereinafter, the adapter used for temporarily holding the optical fiber with respect to the output measuring device is referred to as an output measuring device adapter. By using such an adapter for an output measuring device, the user of the laser treatment device can temporarily fix the tip of the optical fiber to the output measuring device without holding the optical fiber by hand. When the adapter for the output measuring device is used, the position of the optical fiber in the adapter main body for the output measuring device can be kept constant, so that the light output can be measured more accurately.

  As described above, after the calibration is completed, the optical fiber is pulled out from the adapter for the output measuring device for the treatment. Therefore, it is advantageous that the optical fiber can be fixed in the adapter for the output measuring device while the fixed state can be easily released. In medical practice, a person who performs a procedure (such as a doctor) generally wears rubber gloves. Regardless of whether or not rubber gloves are worn, it is beneficial if the optical fiber can be fixed to the output measuring device adapter with a simple operation.

It should be noted that each of the embodiments described below shows a comprehensive or specific example. The numerical values, shapes, materials, components, arrangement and connection forms of components, steps, order of steps, and the like shown in the following embodiments are merely examples. The various aspects described herein can be combined with each other as long as no contradiction arises.

(Embodiment 1)
FIG. 1 illustrates an example of an adapter set for an output measurement device according to the present disclosure. The output measurement device adapter set 100 shown in FIG. 1 includes an output measurement device adapter 1 and a package 3 for packaging the output measurement device adapter 1. Although not shown in FIG. 1, the output measuring device adapter set 100 includes a magnet disposed between the output measuring device adapter 1 and the package 3. As will be described later, this magnet is fixed to the output measuring device adapter 1 by the package 3.

  In the example shown in the figure, an optical fiber 2 is inserted into an adapter 1 for an output measuring device. The output measuring device adapter 1 has a configuration in which the optical fiber 2 can be temporarily fixed. As will be described in detail later with reference to the drawings, the output measuring device adapter 1 includes an adapter main body 4 and a locking member 5 configured to be detachable from the adapter main body 4. The locking member 5 attached to the adapter main body 4 holds the optical fiber 2 so that the optical fiber 2 is not dropped from the adapter main body 4.

  The adapter body 4 includes a body portion 6 including a first end P and a second end Q facing each other along the axis of the optical fiber 2, and a connection portion 7 located at the first end P of the body portion 6. The body portion 6 has a side surface connecting the first end P and the second end Q. In the configuration illustrated in FIG. 1, the package 3 covers the side surface of the body portion 6. As shown in the figure, the package 3 is formed with a tear guide line 14 extending along a first direction different from the direction connecting the first end P and the second end Q of the body portion 6. ing. Details of the configuration of the package 3 will be described later. In the configuration illustrated in FIG. 1, the adapter main body 4 further includes a holding portion 9 having a tube shape connected to the second end Q of the body portion 6. In this example, the optical fiber 2 is inserted into the adapter body 4 through the holding unit 9.

  The adapter set 100 for an output measuring device can be used for calibration of a laser treatment device main body that emits laser light, for example, in a photodynamic treatment method. FIG. 2 shows an example in which the adapter set 100 for an output measuring device is applied to the calibration of a laser output device for photodynamic therapy. Here, calibration in an apparatus in which a laser output apparatus and an output measurement apparatus are integrated is illustrated. The laser output device 20 shown in FIG. 2 has a laser light output terminal 22 and a measurement terminal 24 for measuring the intensity of the laser light on its front surface.

  When calibrating the laser output device 20, first, an adapter set 100 for an output measuring device is prepared. The adapter set 100 for an output measuring device can be brought into a room (for example, a treatment room or an operating room) where a treatment is performed in a state where one end of the optical fiber 2 is connected to the adapter 1 for an output measuring device. Typically, the adapter set 100 for an output measuring device is sterilized in advance by gamma irradiation or the like.

  Next, the tip 8 (see FIG. 1) provided on the adapter main body 4 of the adapter 1 for the output measuring device is inserted into the measurement terminal 24 of the laser output device 20. The adapter set 100 for an output measuring device is fixed to the laser output device 20 by inserting the tip 8 into the measurement terminal 24. By fixing the output measurement device adapter set 100 to the laser output device 20, the optical fiber 2 connected to the output measurement device adapter 1 is optically coupled to the output measurement device in the measurement terminal 24. Next, the other end of the optical fiber 2 is connected to the output terminal 22 of the laser output device 20. The optical fiber 2 may have a connector for connection with the output terminal 22 of the laser output device 20 at the end portion on the side not connected to the output measuring device adapter 1. In this example, the optical fiber 2 is optically coupled to a laser output device in the output terminal 22 via a connector 2 c attached to the other end of the optical fiber 2. The order of connection of the optical fiber 2 to the measurement terminal 24 and connection of the optical fiber 2 to the output terminal 22 is arbitrary.

  Thereafter, when laser light is output from the laser output device 20, the laser light enters the measurement terminal 24 through the optical fiber 2. The output measuring device 20 measures the intensity of the incident laser beam. Thus, calibration is performed in a state where the laser output device 20, the optical fiber 2, and the output measuring device are optically coupled.

  After the calibration, the output measuring device adapter set 100 is removed from the output measuring device 20. At this time, the end of the optical fiber 2 to which the connector 2 c is attached may remain connected to the output terminal 22. After removing the output measurement device adapter set 100 from the output measurement device 20, the locking member 5 (see FIG. 1) is removed from the adapter body 4 of the output measurement device adapter 1 according to the procedure described later. By removing the locking member 5 from the adapter body 4, the fixing of the optical fiber 2 to the output measuring device adapter 1 is released. After releasing the fixation of the optical fiber 2, the end of the optical fiber 2 is pulled out from the inside of the adapter 1 for the output measuring device, and the treatment is performed using the optical fiber 2.

  In this way, if the output measuring device adapter set 100 in which the optical fiber 2 is inserted in the output measuring device adapter 1 is connected to the output measuring device in advance, the user of the output measuring device can use the optical fiber at the time of calibration. There is no need to hold 2 by hand. Therefore, according to the embodiment of the present disclosure, the ease of handling of the optical probe can be improved.

  Hereinafter, the details of the structure of the adapter set 100 for an output measuring device will be described with reference to the drawings.

  3 and 4 show an example of the external appearance of the adapter set 100 for an output measuring device. For reference, FIGS. 3 and 4 show an x-axis, a y-axis, and a z-axis that are orthogonal to each other. In the following description, the x-axis, y-axis, or z-axis may be shown in other figures.

(Adapter body of output measuring device adapter)
As described with reference to FIG. 1, the output measuring device adapter 1 in the output measuring device adapter set 100 includes the adapter main body 4 and the locking member 5 that can be detached from the adapter main body 4. The adapter main body 4 includes a body portion 6 and a connection portion 7 provided on the first end P side of the body portion 6 and connected to the output measuring device. In addition, the method of connection between the output measuring device which measures the intensity | strength of light, and the adapter 1 for output measuring devices is not limited to a specific method. For example, a fitting between a claw and a hole, a connection using a screw, or the like can be applied.

  The body part 6 and the connection part 7 have an internal space into which the optical fiber 2 can be inserted. A through hole (not shown) is provided on the second end Q side of the body portion 6, and the optical fiber 2 is inserted into the internal space of the body portion 6 from this through hole. In the configuration illustrated in FIGS. 3 and 4, the connection portion 7 includes a portion integrally formed with the body portion 6 and a tip portion 8. In this example, the tip 8 has a truncated cone shape. The optical fiber 2 is inserted into the adapter body 4 so that the tip thereof reaches the vicinity of the tip of the tip portion 8.

  The distal end portion 8 is formed of a material capable of transmitting at least laser light emitted from a laser output device in which the output measuring device adapter set 100 is used. Examples of the material constituting the tip 8 are polystyrene, polypropylene, acrylic resin, polyphenylsulfone, polyamide (for example, nylon), polycarbonate, and the like. For example, when the connection portion 7 (here, the tip portion 8 and a portion of the connection portion 7 integrally formed with the body portion 6) is formed using a material that can be sterilized by gamma rays, such as polystyrene and polypropylene, gamma rays are used. This is advantageous because the adapter set 100 for an output measuring device can be sterilized by irradiation.

  The body portion 6 has a side surface connecting the first end P and the second end Q. In the configuration illustrated in FIGS. 3 and 4, the shape of the body portion 6 is generally a quadrangular prism. In other words, here, the cross-sectional shape of the side surface of the body portion 6 when cut along a plane perpendicular to the axis of the optical fiber 2 (yz surface) is approximately a quadrangle, and the side surface of the body portion 6 includes the top surface, the bottom surface, and the front surface. And includes the back. 3 and 4 correspond to a top view and a front view, respectively, of the output measuring device adapter set 100. Note that the terms “upper surface”, “bottom surface”, “front”, and “rear surface” are used for convenience to distinguish the surfaces included in the body portion 6, and the attitude of the adapter set 100 for the output measuring device. Is not intended to limit.

  The body portion 6 has an opening 16 on its side surface that communicates with the internal space of the body portion 6. In this example, the opening 16 is provided on the upper surface of the body portion 6. The locking member 5 of the output measuring device adapter 1 is inserted into the body portion 6 through the opening 16. As a result, the locking member 5 is coupled to the adapter body 4. The locking member 5 is configured to be attachable to and detachable from the adapter main body 4 (here, the body portion 6).

  Moreover, the trunk | drum 6 has the recessed part 18 in the side surface. Here, the concave portion 18 is provided on the bottom surface of the body portion 6. As shown in FIG. 4, a magnet 30 is disposed in the recess 18. The package 3 covers the output measuring device adapter 1 so as to cover the magnet 30 disposed in the recess 18. Therefore, normally, in a state where the package 3 is attached to the output measuring device adapter 1, the magnet 30 is not observed from the outside of the output measuring device adapter 1. The function of the magnet 30 will be described later.

  The trunk | drum 6 is formed from resin, for example. The material constituting the body portion 6 may be the same as the material constituting the connection portion 7 or may be different from the material constituting the connection portion 7. If the body portion 6 is made of a material that can be sterilized with gamma rays, the adapter set 100 for the output measuring device can be sterilized by gamma irradiation, which is beneficial.

  As shown in FIGS. 3 and 4, the adapter main body 4 may have a holding portion 9 connected to a through hole provided on the second end Q side of the body portion 6. In the example described here, the holding portion 9 has a tube shape. In the present specification, the “tube shape” is not limited to a cylindrical shape. “Tube shape” broadly includes shapes whose outline when cut in a cross section perpendicular to the axis is a polygonal shape, an indefinite shape or the like.

  The holding part 9 is made of an elastic material such as rubber, for example. In this specification, “elastic material” means a material having an international rubber hardness of 40 IRHD or more and 60 IRHD or less. International rubber hardness is measured by a measuring method based on JIS K 6253: 2012. The holding unit 3 can be formed of polyurethane, silicone, ethylene propylene rubber, styrene-butadiene rubber, nitrile rubber, latex rubber, or the like. Polyurethane, silicone, ethylene propylene rubber, styrene-butadiene rubber, nitrile rubber and latex rubber are materials that can be gamma sterilized. The holding part 9 may include a portion made of a material other than the elastic material. The holding part 9 may be formed of a material different from the material constituting the connection part 7 and the body part 6. The holding unit 9 prevents the optical fiber 2 from being sharply bent.

  As the optical fiber 2 connected to the output measuring device adapter 1, various optical fibers suitable for guiding the laser beam can be used. For example, the optical fiber 2 may be a single mode or multimode optical fiber, a graded index type polymer optical fiber (GI • POF), a bundle fiber, or the like. There is no restriction | limiting in particular in the diameter of the core of the optical fiber 2, For example, it is about 400 micrometers. The optical fiber 2 may be of a type that can be sterilized by gamma rays.

(Locking member for adapter for output measuring device)
The locking member 5 is coupled to the adapter main body 4 of the adapter for the output measuring device by being inserted into the body portion 6 through the opening 16. The locking member 5 has a protruding portion 13 positioned outside the adapter main body 4 in a state where the locking member 5 is inserted into the body portion 6 of the adapter main body 4. As shown in FIG. 4, in a state where the locking member 5 is inserted into the adapter main body 4, the lower surface of the projecting portion 13 (the surface facing the upper surface of the body portion 6) and the opening 16 provided in the body portion 6. A gap d is formed between the two. In other words, the protruding portion 13 faces the opening 16 through the gap d. As can be seen from FIGS. 3 and 4, in a state where the locking member 5 is inserted into the adapter body 4, at least a part of the package 3 is disposed between the lower surface of the protruding portion 13 and the opening 16. Has been.

  The shape of the protrusion 13 when viewed from the normal direction of the upper surface of the body portion 6 is, for example, a rectangular shape (see FIG. 3). Of course, the shape of the protrusion 13 is not limited to the shape shown in FIG. As shown in FIG. 4, the protrusion 13 may have a flat plate shape. That is, the surface (surface opposite to the lower surface) of the protrusion 13 can be flat. However, the shape of the surface of the protruding portion 13 is not limited to the shape shown in FIG. 4, and may be, for example, an uneven shape or a rounded shape. Details of the shape of the locking member 6 and a method of fixing the optical fiber 2 in the output measuring device adapter 1 using the locking member 6 will be described later.

  The material constituting the locking member 5 may be the same as the material constituting the connection portion 7 or the body portion 6. If the locking member 5 is made of a material that can be sterilized with gamma rays, it is advantageous because the adapter set 100 for the output measuring device can be sterilized by gamma ray irradiation.

(Packaging body)
The packaging body 3 that wraps the output measuring device adapter 1 has a film body 3 b that covers the outer surface of the adapter body 4 of the output measuring device adapter 1. In the configuration illustrated in FIGS. 3 and 4, the film body 3 b covers the outer periphery of the body portion 6 along the circumferential direction of the columnar shape of the body portion 6.

  The film body 3b typically has a tube shape. The shape of the film main body 3b may be any shape that can cover the outer periphery of the adapter main body 4, and is not limited to the tube shape. The length along the tube-shaped axis is not limited to a specific length. When the film body 3b has a tube shape, the cross-sectional shape when cut by a plane perpendicular to the axis of the tube shape is not limited to a specific shape, and may be, for example, a circle or a polygon.

  The film body 3b has a first cleavage guide line 14 formed along the circumferential direction of the tube shape. Therefore, the film main body 3 b can be easily cut along the first cleavage guide line 14. The “cleavage guide line” in the present specification broadly includes structures having a function of regulating the direction of cutting in the film body (may be referred to as the direction of tearing of the film body). For example, the first cleavage guide line 14 can be a perforation formed from an array of small holes. The specific mode of the first cleavage guide line 14 is not limited to the perforation, and a portion (groove) thinner than other portions may be provided along the direction of cutting. For example, the first cleavage guide line 14 may be a notch that is made partway from the surface along the thickness direction of the film body 3b. Such an incision can be formed using, for example, a mold having a blade having a predetermined shape, laser, or heat. A ribbon having higher strength than that of the film main body 3b may be disposed along the direction of cutting in the film main body 3b. In the example described here, the first cleavage guide line 14 is formed in the form of a linear perforation. In this example, the first cleavage guide line 14 includes a semicircular window (opening) 14w that connects the front surface and the back surface of the film body 3b (see FIG. 3).

  FIG. 5 is a development view of the film body 3b shown in FIGS. FIG. 5 shows the film body 3b in a state where the film body 3b is opened by being cut along a direction connecting the first end P and the second end Q of the body portion 6 (the x-axis direction shown in FIGS. 3 and 4). Show. For convenience of explanation, FIG. 5 also shows the protrusion 13 in a state where the locking member 5 is inserted into the adapter body 4.

  As shown in the figure, the film body 3b has two regions defined by a first cleavage guide line 14 formed so as to extend along a first direction (here, the circumferential direction of the body portion 6). Hereinafter, of the two regions defined by the first cleavage guide line 14, the one close to the connection portion 7 of the adapter body 4 is referred to as a first region R 1, and the one close to the holding portion 9 is the second region R 2. Call it. As described with reference to FIGS. 3 and 4, at least a part of the package 3 is located between the lower surface of the protrusion 13 and the opening 16. As shown in FIG. 5, here, the first region R <b> 1 includes a portion that overlaps the protruding portion 13.

  On the other hand, in this example, the second region R2 does not overlap the protruding portion 13. That is, in this example, the second region R2 is not formed between the adapter main body 4 and the protruding portion 13. In the configuration illustrated in FIG. 5, the first cleavage guide line 14 is formed at a position that does not overlap the protrusion 13 when viewed from a direction perpendicular to the upper surface of the protrusion 13. Here, the first cleavage guide line 14 is located above the film main body 3b among the four rectangular sides of the protrusion 13 and slightly outward from the side Sd parallel to the first direction. Is formed. For example, the first cleavage guide line 14 can be formed on the outside of the side Sd by about 1 mm.

  As will be described in detail later, the packaging body 3 has the first cleavage guide line 14, whereby the packaging body 3 can be cut along the first cleavage guide line 14. Thereby, the part corresponding to 1st area | region R1 can be isolate | separated from the trunk | drum 6 in the state which left the part corresponding to 2nd area | region R2 among the film main bodies 3b. At this time, since the first region R1 includes a region disposed between the projecting portion 13 and the opening 16, the first region R1 is lifted by lifting the portion corresponding to the first region R1. The locking member 5 can be pulled up together with the corresponding part. Therefore, the locking member 5 can be easily pulled out from the adapter body 4.

  In the configuration illustrated in FIG. 5, the first cleavage guide line 14 protrudes from the locking member 5 along the direction connecting the first end P and the second end Q of the body portion 6 (here, the x-axis direction). The window part 14w arrange | positioned along with the part 13 is included. In this example, the window portion 14w has a semicircular shape. As shown in the drawing, the width W1 along the first direction in the window portion 14w is larger than the width W2 along the first direction in the protruding portion 13.

  If such a window portion 14w is provided in the middle of the first cleavage guide line 14, the first region R1 and the second region 2 of the film body 3b can be cut without cutting the film body 3b over the entire circumference of the body portion 6. This is advantageous because it can be separated from the region R2. In particular, by providing the window portion 14w in the vicinity of the protruding portion 13 of the locking member 5, when the film main body 3b is cut along the first cleavage guide line 14, the protruding portion 13 interferes with the film main body. It can be prevented that 3b is cut in an unintended direction or the first region R1 and the second region R2 cannot be completely separated in the vicinity of the protrusion 13. That is, the formation of such a window portion 14w in the film body 3b makes it easier to separate the first region R1 and the second region R2 in the film body 3b.

  In the example illustrated in FIG. 5, the outer shape of the window portion 14w includes a straight portion 14s extending along the first direction and curved portions 14t connected to both ends of the straight portion 14s. The straight portion 14s is connected to the first cleavage guide line 14 at both ends thereof. Therefore, when the film main body 3b is cut toward the window portion 14w along the first cleavage guide line 14, if the cut reaches both ends of the linear portion 14s, the first region R1 and the second region of the film main body 3b Region R2 is separated. That is, it is not necessary to cut the film body 3b over the entire circumference of the body portion 6. Note that the shape of the window portion 14w is not limited to a semicircular shape, and may be an arbitrary shape. An opening having a width wider than the protruding portion 13 is formed at a position that is aligned with the protruding portion 13 along the direction connecting the first end P and the second end Q of the body portion 6 and does not overlap the protruding portion 13. If you put it, you can get the same effect.

  In the configuration illustrated in FIG. 5, the film body 3 b has a semicircular shape projecting from the periphery of the film body 3 b toward the connection portion 7 (the negative direction of the x axis shown in FIG. 5) on the bottom surface side of the body portion 6. It has a tab T. Here, the second cleavage guide line 15 extending along the x-axis direction starts from the shoulder Ts, which is a connection point between the rectangular peripheral edge of the film main body 3b and the peripheral edge on the arc of the tab T, and the film main body 3b Is formed. In FIG. 5, the film body 3b has two second cleavage guide lines 15a and 15b. These second cleavage guide lines 15a and 15b do not extend to the periphery of the film body 3b opposite to the periphery on which the tab T is provided, and the second cleavage guide lines 15a and 15b. Is located in the film body 3b. As can be seen from the fact that the tab T is provided on the bottom surface side of the body portion 6, the second cleavage guide lines 15a and 15b are provided at positions that do not overlap with the opening 16 (see FIG. 3) of the body portion 6. ing. In this example, the first cleavage guide line 14 extends from a position where it intersects with the second cleavage guide line 15a or 15b, and includes the tab T and the two second cleavage guide lines 15a and 15b. The first cleavage guide line 14 is not formed in the intermediate region.

  When the film main body 3b shown in FIG. 5 is used, for example, after the calibration is finished, the tab T can be pulled along the direction in which the second cleavage guide lines 15a and 15b extend while pinching the tab T. Thereby, the film main body 3b can be cut along the second cleavage guide lines 15a and 15b. When the film body 3b is cut along the second cleavage guide lines 15a and 15b, the shoulder Ts appears as a corner. Therefore, the film body 3b can be cut along the first cleavage guide line 14 while pinching the shoulder Ts. Thus, by providing the tab T and the second cleavage guide line 15, the separation of the first region R1 and the second region R2 in the film body 3b becomes easier.

  Similar to the first cleavage guide line 14, the second cleavage guide line 15 may be a perforation, a cut, or the like. Note that the second cleavage guide line 15 may have a configuration different from that of the first cleavage guide line 14, for example, the first cleavage guide line 14 is a perforation, and the second cleavage guide line. 15 may be a notch. In addition, when the 2nd cleavage guide line 15 is a perforation, the small hole in the outer edge vicinity of the film main body 3b may have a shape different from the small hole of another part. For example, the small hole in the vicinity of the outer edge of the film body 3b may have an oval shape having a long axis in the direction in which the second cleavage guide line 15 extends. At this time, the small holes near the outer edge of the film main body 3b may have an arrangement in which only a part thereof overlaps the film main body 3b. In other words, a slit-shaped notch may be formed at the end of the film body 3b by the outer edge of the film body 3b and the outline of the small hole being continuous. Thus, cutting along the direction of the second cleavage guide line 15 is facilitated by making the shape of the end of the film body 3b into a notch shape. Furthermore, you may give the 2nd axis | shaft to the film main body 3b by extending | stretching along two or more directions. That is, in the film main body 3b, the second axial direction at the time of stretching may be set so that the cutting can easily proceed in the direction of the second cleavage guide line 15.

  As shown in FIG. 5, the film body 3b may have a notch Cf on the opposite side of the tab T in the tube-shaped axial direction (x-axis direction). The outline of the notch Cf is typically a shape that matches the outline of the tab T. The film body 3b is produced, for example, by cutting a long film or a film having a cylindrical shape extending along a certain axial direction with a certain length. When such a manufacturing method is adopted, by adjusting the shape of the cut portion, it is possible to easily produce a plurality of film main bodies 3b having the same shape and having the tab T at the end of the tube shape.

  As shown in FIG. 5, the display 3a formed from a character, a figure, a symbol, or a combination thereof may be provided on the surface of the film body 3b. The display 3a may be an instruction regarding a method for handling the adapter set 100 for an output measuring device. By displaying instructions on how to handle the output measuring device adapter set 100 on the surface of the film body 3b, the output measuring device adapter set 100 is damaged and / or caused by use under an incorrect usage method. The occurrence of fouling can be suppressed.

  In the configuration illustrated in FIG. 5, the display 3 a is drawn with the number “1” and the figure drawn thereunder, the number “2” and the trapezoid drawn thereunder, and the number “3” and adjacent thereto. It includes an arrow and the number “4” and an arrow drawn adjacent to it. These show how to handle the adapter set 100 for an output measuring device after calibration. That is, the number “1” and the graphic drawn below indicate that after the calibration is performed, the tab T is first moved downward in the figure while pinching the tab T (procedure 1). Thereby, as shown in FIG. 6, the film main body 3b is cut along the second cleavage guide lines 15a and 15b, and includes a ribbon shape including a region sandwiched between the tab T and the second cleavage guide lines 15a and 15b. Is formed on the film body 3b. The number “2” and the trapezoid drawn below indicate that the shoulder Ts is moved to the left and right of the figure while pinching the shoulder Ts (procedure 2). Thereby, as shown in FIG. 7, the film main body 3b is cut along the first cleavage guide line. When the cut reaches the window portion 14w (see FIG. 5), the first region R1 and the second region R2 of the film body 3b are separated. The numeral “3” and the arrow drawn adjacent thereto indicate that the ribbon-shaped first region R1 is lifted and the locking member 5 (fixing pin) is pulled out (see step 3 and FIG. 8). . As will be described later, by lifting the ribbon-shaped first region R1, the locking member 5 is pulled out from the body portion 6, and the fixation of the optical fiber 2 to the output measuring device adapter 1 is released. The number “4” and the arrow drawn adjacent thereto indicate that the optical fiber 2 is pulled out from the adapter body 4 along the direction from the first end P to the second end Q of the body portion 6 (procedure 4). ). Thereby, the optical fiber 2 can be separated from the adapter body 4 (see FIG. 9). The above steps 1 to 4 may be executed with the output measurement device adapter 1 connected to the output measurement device, or may be executed after the output measurement device adapter 1 is removed from the output measurement device. Good.

  In the example shown in FIG. 5, the display 3 a includes an explanatory text indicating that the film is turned after calibration (after power check). In the example shown in FIG. 5, the display 3 a further includes instructions regarding a calibration procedure during the procedure so that it can be referred to when calibration is required during the procedure. Here, the display 3a includes two circles, and it is shown that the optical fiber 2 is inserted into the adapter body 4 so that the end of the optical fiber 2 reaches the tip of the tip 8 in one of the circles. ing. In the other circle, it is shown that the optical fiber 2 is fixed by sandwiching a portion of the optical fiber 2 outside the holding unit 9 with a slit provided in the holding unit 9. In addition, the aspect in which the slit was provided in the holding | maintenance part 9 and the procedure of the calibration in the middle of the treatment in such an aspect are demonstrated as Embodiment 2. FIG.

  It is beneficial if the display 3a on the film body 3b is blue. According to the study by the present inventors, when the color of the display 3a is blue, discoloration due to gamma ray irradiation can be suppressed. Therefore, it is possible to prevent misrecognition of display contents due to discoloration of the display. Moreover, since a clear display in which discoloration is suppressed can be realized, the fact that the display is blue makes it possible for a practitioner such as a doctor to quickly grasp the display contents. Therefore, a rapid treatment can be realized. The display 3a may include instructions regarding a calibration procedure, a disposal procedure of the output measuring device adapter set 100, and the like. For example, the locking member 5 and / or the holding part 9 may be blue. In the present specification, “blue” means a color having an x value of 0.3 or less and a y value of 0.4 or less on the chromaticity diagram in the CIE 1931 xyY color space. The x and y values on the chromaticity diagram can be measured using a colorimeter or spectrocolorimeter.

  The film body 3b can be formed of a heat-shrinkable film having a property of shrinking by heat. The heat-shrinkable film is obtained by stretching a resin film along a certain axial direction. Such a heat-shrinkable film is easy to tear along the axial direction. Therefore, the axial direction at the time of stretching may be set so that the cutting proceeds easily along the direction of the first cleavage guide line 14. When the film body 3b is composed of a heat-shrinkable film, the packaging body 3 is heated after being mounted so as to cover the adapter body 4 (here, the body portion 6). By heating, the film main body 3b can be more closely attached to the adapter main body 4 using heat shrinkage.

  Examples of the material constituting the film body 3b are polyolefin, polystyrene, polyvinyl chloride, polypropylene and the like. These are materials that can be gamma sterilized. In particular, among these, since polystyrene hardly undergoes discoloration due to gamma ray irradiation, it is beneficial if the film body 3b is made of polystyrene.

(magnet)
FIG. 10 schematically shows a cross-section when the body part 6 is cut along a plane including the columnar axis of the body part 6 (here, the zx plane). In FIG. 10, the upper half of the body portion 6 and the optical fiber 2 are not shown. As shown in the figure, the body portion 6 has a concave portion 18 on its side surface (here, the bottom surface), and a magnet 30 is disposed in the concave portion 18. Here, the direction connecting the N pole and the S pole of the magnet 30 is parallel to the direction connecting the upper surface and the bottom surface of the body portion 6 (z direction in FIG. 10). The magnet 30 is typically not joined to the body portion 6, and is fixed to the output measuring device adapter 1 by the packaging body 3 covering the output measuring device adapter 1.

  FIG. 11 shows a state in which the output measurement device adapter set 100 is attached to the housing of the output measurement device 20 shown in FIG. Typically, the housing of the output measuring device has at least a portion made of iron. Therefore, the output measuring device adapter set 100 has the magnet 30 fixed to the output measuring device adapter 1 by the package 3 so that the output measuring device adapter set 100 is temporarily fixed to the housing of the output measuring device. Is possible. For example, when the upper surface and the side surface of the housing of the output measuring device 20 described with reference to FIG. 2 are made of iron, the output measuring device adapter set 100 can be attached to the upper surface or the side surface of the output measuring device 20. . Therefore, for example, after the calibration is completed, the adapter body 4 after the optical fiber 2 is pulled out can be temporarily attached to the upper surface or the side surface of the output measuring device 20. Thereby, loss of the adapter main body 4 can be prevented. The tip of the optical fiber 2 pulled out from the adapter body 4 is inserted into, for example, a biopsy channel (or suction channel) of an endoscope and directed toward an irradiation target.

  The film body 3b has a smaller thickness than an iron plate or the like. Therefore, the magnet 30 arranged in the recess 18 of the body part 6 is fixed to the body part 6 by the film main body 3b of the packaging body 3, so that the magnet 30 is fixed to the body part 6 using, for example, an iron plate. Thus, a larger adsorption force can be obtained. According to the studies by the inventors, a value of 100 mT is obtained as the magnetic flux density on the film surface by using a polystyrene film having a thickness of 50 μm. The suction force for an iron plate having a thickness of 1 mm can be, for example, about 0.40 kgw. The attractive force is the force at the moment the magnet leaves the iron plate when the magnet is placed on the iron plate with the N or S pole facing the iron plate and pulled away from the iron plate by pulling the magnet perpendicular to the surface of the iron plate. Means the size of The suction force can be measured using, for example, a force gauge.

  Typically, the recessed part 18 is provided in the body part 6 in the position which overlaps with 2nd area | region R2 (refer FIG. 5) of the film main body 3b. In this case, even if the first region R <b> 1 is removed by cutting the film body 3 b along the first cleavage guide line 14, the magnet 30 does not fall off from the body portion 6. Therefore, disposal of the adapter set 100 for an output measuring device after use is easy.

  Next, a fixing mechanism of the optical fiber 2 using the locking member 6 will be described with reference to FIGS. 12 and 13A to 13C.

  FIG. 12 shows the inside of the adapter 1 for an output measuring device. FIG. 12 is a cross-sectional view showing the body portion 6 and a part of the connection portion 7 formed integrally with the body portion 6 by removing the package 3. FIG. 12 shows the optical fiber 2 and the locking member 5 inserted into the adapter body 4 together. FIG. 12 is a cross-sectional perspective view of the body section 6 taken along a plane parallel to the bottom surface of the body section 6 and including the axis of the optical fiber 2. In the illustrated example, a groove is formed in the center along the longitudinal direction of the body portion 6 inside the body portion 6 and the connection portion 7, and the optical fiber 2 is disposed in the groove. Typically, the optical fiber 2 has a circular shape in a cross section perpendicular to the axis. The cross section of the groove for arranging the optical fiber 2 may have a C shape with a part of a circle missing.

  The optical fiber 2 may have a fitting member 10 that fits with the locking member 5. The fitting member 10 is made of, for example, plastic. It is advantageous that the plastic surface of the fitting member 10 is processed so as not to damage the coating of the optical fiber 2. The fitting member 10 covers at least a part of the peripheral surface of the optical fiber 2. The fitting member 10 is fitted with the locking member 5. This fitting structure will be described in more detail below.

  FIG. 13A shows the locking member 5 and the optical fiber 2 in an enlarged manner. In the configuration illustrated in FIG. 13A, a recess 11 is formed in the fitting member 10. For example, the recess 11 is formed at two locations facing each other along the diameter direction of the optical fiber 2 in a cross section perpendicular to the axis of the optical fiber 2. Here, grooves having a certain width in the direction along the axis of the optical fiber 2 are fitted on both sides of the fitting member 10 in the direction in which the locking member 5 is inserted and in the direction perpendicular to both the axis of the optical fiber 2. The joint member 10 is formed from above to below. Each of these two grooves has a bottom surface on the optical fiber 2 side.

  The locking member 5 may have at least two legs 12 that face each other. The leg portion 12 is a portion that is inserted into the adapter body 4. In the illustrated example, the leg portions 12 face each other, and each has a rectangular parallelepiped shape. As illustrated, the leg portion 12 is connected to the protruding portion 13. The protruding portion 13 is disposed outside the adapter body 4 when the locking member 5 is inserted into the adapter body 4. As described above, the locking member 5 is inserted into the opening 16 provided in the body portion 6. The opening 16 is provided, for example, closer to the connecting portion 7 than the center of the body portion 6. Typically, the area of the opening 16 is smaller than the area of the protrusion 13. Therefore, the leg portion 12 is inserted into the adapter main body 4 through the opening 16, whereas the protruding portion 13 protrudes outside the adapter main body 4 without passing through the opening 16. The range of the length from the upper surface of the protrusion 13 to the tip of the leg 12 is typically 18 mm to 23 mm. The length from the upper surface of the protrusion 13 to the tip of the leg 12 may be 21 ± 2 mm.

  Typically, the width of the recess 11 in the direction along the axis of the optical fiber 2 is slightly larger than the width of the leg 12. Further, the interval between the leg portions 12 facing each other is larger than the distance between the bottom surfaces of the recesses 11. Further, the distance between the opposing leg portions 12 is smaller than the length obtained by adding the depth of the two concave portions 11 and the distance between the bottom surfaces of the concave portions 11. By adopting such a configuration, the leg portion 12 can sandwich the concave portion 11 by sliding into the body portion 6 from above the fitting member 10.

  Thus, the leg portion 12 of the locking member 5 is inserted into the trunk portion 6 via the opening 16 provided on the outer surface of the trunk portion 6. The optical fiber 2 is held in the internal space of the body portion 6 by the locking member 5 (typically, the tip thereof). That is, the locking member 5 holds the optical fiber 2 in a state where it is inserted into the body portion 6.

  13B and 13C show a cross section when the adapter 1 for an output measuring device is cut along a plane (yz plane) perpendicular to the axis of the optical fiber 2. In FIG. 13B and FIG. 13C, illustration of the package 3 is omitted.

  FIG. 13B shows a state in which the locking member 5 is starting to be inserted into the adapter body 4. In the state shown in FIG. 13B, the concave portion 11 of the fitting member 10 and the leg portion 12 of the locking member 5 are not yet fitted. FIG. 13C shows a state in which the concave portion 11 of the fitting member 10 and the leg portion 12 of the locking member 5 are fitted. As can be seen from these drawings, the engaging member 5 is inserted into the adapter main body 4 through the opening 16 provided in the body portion 6 so that the leg portion 12 sandwiches the concave portion 11, thereby fitting the member. 10 and the locking member 5 can be fitted. Thereby, the optical fiber 2 can be fixed by the locking member 5. When the locking member 5 is pulled out from the adapter main body 4, the fixed state of the locking member 5 and the fitting member 10 is released, and the optical fiber 2 can be pulled out from the adapter main body 4.

  In the configuration illustrated in FIG. 13A, the locking member 5 has a groove portion 19 between the protruding portion 13 and the two leg portions. As shown in FIG. 13C, the surface Ss on the side close to the leg portion 12 of the two surfaces facing each other through the groove portion 19 in the locking member 5 typically has the locking member 5 on the body portion 6. In the inserted state, it aligns with the upper surface of the body portion 6 (in this example, the surface provided with the opening 16).

  As shown in FIG. 13C, the protruding portion 13 faces the opening 16 of the trunk portion 6 through the gap d in a state where the locking member 5 is inserted into the trunk portion 6. Note that the gap d shown in FIG. 13C is exaggerated for the sake of explanation, and does not indicate the actual size of the gap. In the illustrated example, the lower surface of the protrusion 13 that faces the opening 16 (the surface that faces the surface Ss) is typically parallel to the plane defined by the contour of the opening 16. However, the arrangement of the protrusions 13 is not limited to this example. The lower surface of the protruding portion 13 may not be parallel to the plane defined by the outline of the opening 16. Note that the lower surface of the protruding portion 13 is typically flat.

  14A is a top view when the adapter 1 for an output measuring device is viewed from a direction perpendicular to the main surface of the protruding portion 13 (the upper surface or the lower surface of the protruding portion 13, here the upper surface Su shown in FIG. 14A). It is. 14B is a side sectional view corresponding to FIG. 14A. As shown in FIG. 14A, here, the first cleavage guide line 14 is formed in parallel with the rectangular side Sd of the protrusion 13. As shown in the drawing, at least a part of the film body 3 b of the package 3 is disposed between the protruding portion 13 and the opening 16 of the body portion 6. Here, a part of the film body 3b in the first region R1 is disposed in the gap d (see FIG. 13C).

  FIG. 15 is a view for explaining an operation when the locking member 5 is pulled out from the adapter main body 4. For example, after the calibration is completed, the first region R1 and the second region R2 are separated by dividing the package 3 along the first cleavage guide line 14. Since the film main body 3b has the first cleavage guide line 14, the package 3 can be divided along a predetermined direction without using a tool such as scissors. As described above, the first region R <b> 1 includes a region disposed between the protruding portion 13 and the opening 16. Therefore, when the packaging body 3 is cut along the first cleavage guide line 14, a part of the first region R1 remains in the groove portion 19. Therefore, the locking member 5 can be lifted by lifting the first region R1 (typically a ribbon) (Procedure 3 described with reference to FIG. 8). Thereby, the locking member 5 can be easily separated from the body portion 6. That is, the optical fiber 2 can be easily released and the optical fiber 2 can be pulled out from the adapter body 4. In addition, it is advantageous to form the window part 14w in the film main body 3b at a position where it does not overlap the protruding part 13 from the viewpoint of lifting the locking member 5 stably by the first region R1.

  Thus, according to the present disclosure, the holding of the optical fiber 2 with respect to the output measuring device can be easily released after the calibration is completed. For example, in the medical field, the user of the adapter 1 for an output measuring device often wears rubber gloves for hygiene management. Since the output measuring device adapter set 100 includes the packaging body 3, the locking member 5 can be easily pulled out of the body portion 6 using the packaging body 3 even if the glove is worn. Further, even when the portion of the locking member 5 protruding from the adapter body 4 (here, the protruding portion 13) is small, the locking member 5 is compared with the case where the protruding portion 13 is directly pinched with the fingertip. Can be easily extracted from the body portion 6. Therefore, according to the present disclosure, in a scene where it is required to work quickly and accurately, for example, at a medical site, a quick work can be performed even when a small part is handled manually.

  In the embodiment of the present disclosure, the locking member 5 is pulled out while pinching the first region R1 separated from the second region R2 that covers the body portion 6. Therefore, it is not necessary to directly touch the locking member 5 when releasing the fixation of the optical fiber 2 in the output measuring device adapter 1. Therefore, the contamination of the adapter 1 for output measuring devices can be suppressed, and the risk of infection to the treatment subject (for example, a patient) can be reduced.

(Modification of locking member)
FIG. 16 shows a modification of the locking member used in the adapter set for an output measuring device. The locking member 5a shown in FIG. 16 is L-shaped as a whole and does not have the groove 19 (see FIG. 15). That is, the locking member 5a shown in FIG. 16 has two leg portions 12a facing each other and a protruding portion 13 connected substantially perpendicular to the leg portion 12a.

  When the locking member 5 having the groove portion 19 is used like the locking member 5 shown in FIG. 15, the locking member 5 is inserted into the opening 16 of the body portion 6 and then the body portion 6 having a columnar shape, for example. If the film main body 3b is slid along the longitudinal direction, the packaging body 3 can be attached to the adapter main body 4. Then, the film main body 3b is closely attached to the trunk | drum 6 by heating the film main body 3b as needed.

  On the other hand, the locking member 5 a shown in FIG. 16 does not have the groove 19. Therefore, after attaching the packaging body 3 to the adapter body 4, the leg portion 12 a of the locking member 5 a can be inserted into the opening 16 of the body portion 6. In addition, the opening 16 of the trunk | drum 6 should just be a magnitude | size which can insert the leg part 12a of the latching member 5a. When such a locking member 5a is used, the first region R1 of the film body 3b can include a region disposed on the opening 16. At this time, the protruding portion 13 faces the opening 16 through a gap that is the same as the thickness of the film main body 3b or larger than the thickness of the film main body 3b.

  FIG. 17 is a view for explaining an operation when the locking member 5 a is pulled out from the adapter body 4. The adapter set for an output measuring device having the locking member 5a can also be used in the same manner as the usage example described with reference to FIG. For example, after the calibration is completed, the first region R1 and the second region R2 are separated by dividing the package 3 along the first cleavage guide line 14. Here, since 1st area | region R1 contains the area | region which overlaps with the protrusion part 13, it cuts the package 3 along the 1st cleavage guide line 14, and it is a locking member by lifting up 1st area | region R1. 5a can be lifted. Thereby, the locking member 5a can be easily separated from the body portion 6.

(Modification of package)
18A and 18B show another example of the film body included in the package 3. FIG. 18B shows a state where the film body 3ba shown in FIG. 18A is turned upside down.

  The film main body 3ba shown in FIGS. 18A and 18B has tabs Ta protruding from the tube-shaped end portions along the tube-shaped axis, like the film main body 3b described with reference to FIG. Here, the shape of the tab Ta is a trapezoid. In the illustrated example, cleavage guide lines 15a and 15b extending along a tube-shaped axis are provided on the left and right of the tab Ta. Here, the cleavage guide lines 15a and 15b extend beyond the first cleavage guide line 14 from the outer edge of the film body 3ba.

  When the film body 3ba shown in FIGS. 18A and 18B is used, for example, after the calibration is completed, the tab Ta can be pulled along the extending direction of the cleavage guide lines 15a and 15b while pinching the tab Ta. Thereby, the film main body 3ba can be cut along the cleavage guide lines 15a and 15b (Procedure 1 described with reference to FIG. 6). At this time, the tab Ta may be cut off. By cutting the film body 3ba along the cleavage guide lines 15a and 15b, a part that is continuous with the tab Ta across the cleavage guide line 15a, and a part that is continuous with the tab Ta across the cleavage guide line 15b Can be pinched with your fingertips. By pinching these parts with a fingertip and pulling along the first cleavage guide line 14, the package 3 can be easily moved along the first cleavage guide line 14 with the first region R1 and the second region R2. (Procedure 2 described with reference to FIG. 7).

  The package 3 having the film main body 3ba can also be used in the same manner as the use example described with reference to FIG. That is, the locking member 5 can be lifted by cutting the package 3 along the first cleavage guide line 14 and lifting the first region R1 (typically ribbon-shaped). Therefore, the holding of the optical fiber 2 can be easily released.

  The package 3 may have a third cleavage guide line 17 that extends from the end opposite to the connection part 7 to the first cleavage guide line 14 along the longitudinal direction of the body part 6. In this way, after separating the first region R1, by cutting the packaging body 3 along the third cleavage guide line 17, the portion of the film body 3ba corresponding to the second region R2 is removed from the adapter body. 4 can be easily removed. That is, the packaging body 3 can be easily replaced. Moreover, since the magnet 30 (for example, refer FIG. 10) accommodated in the recessed part 18 of the trunk | drum 6 can be taken out from the adapter main body 4, the magnet 30 can be separated from another member and discarded or collect | recovered.

  In the example shown in FIGS. 18A and 18B, the film body 3ba further includes a cleavage guide line 17a that extends from the first cleavage guide line 14 to the outer edge of the film body 3ba and that is continuous with the third cleavage guide line 17. ing.

(Embodiment 2)
FIG. 20 illustrates another example of the adapter set for an output measurement device according to the present disclosure. An output measurement device adapter set 100A shown in FIG. 20 includes an output measurement device adapter 1A and a package 3 that wraps the output measurement device adapter 1A. The adapter main body 4A of the output measuring device adapter 1A has a holding portion 9A provided with a slit 9s extending along a direction connecting the first end P and the second end Q of the body portion 6. The slit 9s extends toward the second end Q from the end far from the second end Q of the body portion 6 in the holding portion 9A.

  The width of the slit 9s is the same as or slightly smaller than the diameter of the optical fiber 2. Therefore, by inserting the optical fiber 2 into the slit 9s, the optical fiber 2 can be temporarily fixed to the adapter body 4A of the output measuring device adapter 1A as shown in FIG. According to such an aspect, the optical fiber 2 can be fixed to the adapter body 4 even after the locking member 5 is separated from the adapter body 4. Therefore, even if the calibration needs to be performed again during the treatment, the adapter main body 4A can be used as the adapter for the output measuring device. When the calibration is performed again during the treatment, the tip of the optical fiber 2 is pulled out from, for example, the endoscope, and the tip of the optical fiber 2 is held by the holding unit so that the tip of the optical fiber 2 reaches the vicinity of the tip of the tip 8 of the adapter body 4A. Insert into the adapter body 4A from the 9A side. Thereafter, when the optical fiber 2 is sandwiched between the slits 9s of the holding portion 9A, the optical fiber 2 can be fixed to the adapter body 4A. After the calibration is completed, the optical fiber 2 can be easily released from the adapter body 4A by removing the optical fiber 2 from the slit 9s. The number, position, and length of the slits 9s in the holding unit 9A can be arbitrarily set.

  Further, as shown in FIG. 22, the vicinity of the tip of the optical fiber 2 may be held in the slit 9s of the holding portion 9A. Since the holding portion 9A has the slit 9s, the practitioner can use the adapter body 4A as a holder for the optical fiber 2. For example, the adapter body 4A may be attached to the housing of the output measuring device by the magnetic force of the magnet 30 held on the adapter body 4A by the package 3, and the tip of the optical fiber 2 may be sandwiched between the slits 9s as shown in FIG. As described above, according to the second embodiment of the present disclosure, the practitioner can easily remove his / her hand from the optical fiber 2 and perform other operations.

  According to the embodiment of the present disclosure, the handling of the optical probe is improved. The adapter set for an output measurement device according to the present disclosure is useful for calibration of a laser output device in PDT, for example.
