JP5561176B2 - Diagnostic packaging and probe adjustment jig - Google Patents

Description

  The present invention relates to a diagnostic package including a probe, an adjustment jig, a tray, and a packaging bag, and also relates to a probe adjustment jig used therefor.

  Various techniques have been proposed and put into practical use for observing and detecting a lesion state of a living tissue. In particular, endoscopes are widely used. The endoscope is inserted into the body lumen, the observation site of the biological tissue is illuminated by the illumination light emitted from the distal end portion of the endoscope, and the observation site of the biological tissue is photographed by the distal end portion of the endoscope. An image photographed by the endoscope is transmitted to an output device such as a display device and a printing device, and is output from the output device.

  The color tone of the photographed image is affected by the combination of the endoscope and the illumination light, the usage time, and the like. Therefore, there may be a difference between the color tone of the photographed image and the actual color tone. In order to reduce such color misregistration, it is necessary to adjust white balance.

Patent Documents 1 to 3 disclose jigs used for white balance adjustment. Patent Document 4 discloses a white balance adjustment system.
In the technique described in Patent Document 1, a jig is provided like a cap, and the white balance is adjusted by covering the tip of the endoscope with the jig.
In the technique described in Patent Document 2, a rotating disk is attached to the tip of a cylindrical member of a jig, and a plurality of color charts are provided on the rotating disk. The color chart facing the distal end of the endoscope can be switched by rotating the turntable with the endoscope inserted into the cylindrical member.
In the technique described in Patent Document 3, both ends of the first tubular member are opened, and the first tubular member is inserted into the bottomed tubular second tubular member. When the endoscope is inserted into the first tubular member, the second tubular member is driven in the axial direction by the driving device, and the distance between the bottom of the second tubular member and the distal end of the endoscope is automatically adjusted.
The technology described in Patent Document 4 automatically adjusts the white balance by photographing a white portion displayed on a display monitor with an endoscope.

  In addition to image diagnosis using an endoscope, a technique for making a diagnosis using fluorescence has been proposed. In order to make a diagnosis using fluorescence, the measurement site is irradiated with excitation light so that fluorescence is emitted from the measurement site of biological tissue, and the wavelength and intensity of the generated fluorescence are analyzed. In order to make such a diagnosis, a probe has been developed and used for diagnosis of a disease state (for example, disease type or infiltration range) such as degeneration of a living tissue or cancer.

  This type of probe includes a light projecting optical fiber, a light receiving optical fiber, and a lens. Excitation light emitted from the tip of the light projecting optical fiber is projected onto the measurement site of the living tissue by the lens, and fluorescence emitted from the measurement site of the living tissue is projected onto the tip of the light receiving optical fiber by the lens. The fluorescence incident on the light receiving optical fiber is transmitted to the spectrum analyzing apparatus by the light receiving optical fiber, and the spectrum analysis of the fluorescence is performed by the apparatus.

  Generally, there are individual differences in the characteristics of optical fibers and lenses for each probe. For this reason, the analysis results obtained by the spectrum analyzer differ from probe to probe. Therefore, it is necessary to perform calibration before making a diagnosis using the probe. However, the work related to calibration is complicated and cumbersome, and it is necessary to avoid as much as possible to force such a calibration work to the user in the medical field.

By the way, it is conceivable to use the jigs described in Patent Documents 1 to 3 for probe calibration. However, these jigs are large-scale. A simple jig is desired for the probe calibration.
In addition, the jigs described in Patent Documents 1 to 3 are based on the premise that they are repeatedly used. If the color chart or the like deteriorates over time, accurate calibration and white balance adjustment cannot be performed. Even the technique described in Patent Document 4 is affected by the degree of color development of the display monitor, aging, or the use environment, and accurate calibration and white balance adjustment cannot be performed.

  Therefore, the problem to be solved by the present invention is to enable easy calibration without forcing the user to perform complicated work related to calibration. The problem to be solved by the present invention is to enable calibration of a probe with a simple configuration. The problem to be solved by the present invention is to eliminate the influence of aging and the like and to perform more accurate calibration.

According to the present invention, since the probe and the adjustment jig are bundled and wrapped in the packaging bag, it is not necessary to prepare a large-scale adjustment jig different from the adjustment jig.
Further, when the user opens the packaging bag, the user notices the presence of the adjusting jig. Therefore, the user must remember to perform calibration using the adjustment jig before making a diagnosis using the probe.

As shown in FIGS. 1 and 2, the diagnostic package 1 includes a probe 10, an adjustment jig 30, a light shielding cover 60, a tray 70, a cover 80, a packaging bag 90, and the like.

  The probe 10 is a cable material that transmits, projects, and receives light. The proximal end portion of the probe 10 is a connector 11 for inputting / outputting light, the distal end portion of the probe 10 is a light projecting / receiving portion 12 for projecting / receiving light, and an intermediate portion of the probe 10 is projected with the connector 11. This is a cable body 13 that transmits light between the light receivers 12. The light projecting / receiving unit 12 is connected to the distal end of the cable body 13, and the connector 11 is connected to the proximal end of the cable body 13.

  When the probe 10 is used, the connector 11 is connected to the base unit 100 (shown in FIGS. 8 and 9; details of the base unit 100 will be described later), and the light projecting / receiving unit 12 is inserted into the lumen. Excitation light emitted from the light source of the base unit 100 is input to the connector 11 at the proximal end portion of the probe 10, and the input excitation light is transmitted to the light projecting / receiving portion 12 at the distal end portion by the cable body portion 13. The excited excitation light is irradiated from the light projecting / receiving unit 12 to the measurement site of the living tissue in the lumen. The measurement site emits fluorescence by excitation light.

Is output. The base unit 100 performs spectral analysis of the fluorescence input to the base unit 100. Using the probe 10 as described above, an optical diagnosis is performed by the probe 10.

  This probe 10 is disposable. That is, from the viewpoint of hygiene, the probe 10 that is once inserted into the lumen is not reused.

  The adjustment jig 30 is used before the probe 10 is inserted into the lumen and used. When the adjustment jig 30 is used, the light projecting / receiving portion 12 of the probe 10 is held by the adjustment jig 30 and the connector 11 of the probe 10 is connected to the base unit 100. Then, light of known standard intensity emitted from the light source of the base unit 100 is projected from a light projecting / receiving unit 12 of the probe 10 onto a part of the adjustment jig 30 (calibration target), and the reflected light thereof is projected and received. 12, and the received light is transmitted to the base unit 100 by the probe 10. In the base unit 100, the intensity of the input light is measured, and calibration is performed by taking into account the difference between the measured intensity and the known standard intensity.

  The light projecting / receiving window 20 may be provided on the side surface of the holder 19. In that case, a mirror is disposed inside the holder 19 and in front of the lens 17, and excitation light projected by the lens 17 is reflected by the mirror toward the light projecting / receiving window 20. The fluorescence emitted from the measurement site of the living tissue and transmitted through the light projecting and receiving window 20 is reflected toward the lens 17 by the mirror.

The connector storage portion 73 is a concave portion provided in the upper surface of the tray main body 71. The connector housing 73 is connected to the cable housing 74 and extends in the tangential direction of the cable housing 74. The front end storage portion 75 is a recess provided in the tray body 71. The distal end storage portion 75 is connected to the cable storage portion 74 and extends in the tangential direction of the cable storage portion 74.

[Adjustment jig]
The adjustment jig 30 will be specifically described.
FIG. 4 is a perspective view of the distal end portion of the probe 10 and the adjustment jig 30. FIG. 4 shows a state where the tip of the probe 10 is removed from the adjustment jig 30. FIG. 5 is a cross-sectional view of the adjustment jig 30. FIG. 5 shows a state in which the probe 10 and the adjustment jig 30 are stored in the tray 70.

  4 and 5, the adjustment jig 30 includes a jig body 31, a light shielding sheet 41, a strip 50, a first calibration target 51, a second calibration target 52, and the like.

  The jig body 31 is a cap that covers the distal end portion of the probe 10, that is, the light projecting / receiving portion 12. The jig body 31 has a light shielding property. If the material itself of the jig body 31 is not light-shielded, the surface of the jig body 31 is coated with a light-shielding coating.

  The jig body 31 has a bottomed cylindrical shape. Specifically, the insertion hole 34 is formed inside the cylindrical portion 36 of the jig main body 31, the cylindrical portion 36 surrounds the insertion hole 34, and one end of the insertion hole 34 is the jig main body 31. The insertion hole 34 extends linearly from the one end surface 32 of the jig main body 31 toward the other end surface 33 of the jig main body 31, and the bottom 35 is the other end surface 33 of the jig main body 31. The other end of the insertion hole 34 is closed.

  A stopper 37 is projected on the inner wall of the insertion hole 34. The stopper 37 is separated from the contact surface of the insertion hole 34, that is, the bottom 35, and is disposed between the opening of the insertion hole 34 and the bottom 35. Specifically, the stopper 37 is disposed in the middle of the insertion hole 34. The stopper 37 is provided in a ring shape so as to surround the center line of the insertion hole 34, a hole 38 is formed inside the stopper 37, and the center line of the insertion hole 34 passes through the hole 38. When the jig body 31 is formed by injection molding, it is preferable that the parting line is formed on the stopper 37 so as to surround the inner region corresponding to the stopper 37 by the joint of the mold.

  A light shielding sheet 41 is attached to the inner wall of the insertion hole 34. The light shielding sheet 41 is bent into a cylindrical shape along the cylindrical portion 36 of the jig body 31. The light shielding sheet 41 is made of a polyurethane foam material (maltoprene) having elasticity, or a knitted or woven telemp having cushioning properties. The shading sheet 41 may be flocked. In addition, the inner wall of the insertion hole 34 may be embossed or embossed instead of sticking the light shielding sheet 41.

  Slits 39 and 40 are formed in the cylindrical portion 36 of the jig body 31. The slits 39 and 40 penetrate from the surface of the jig body 31 (the circumferential surface of the cylindrical portion 36) to the insertion hole 34. The slit 39 and the slit 40 are arranged symmetrically with respect to the center line of the insertion hole 34. The slits 39 and 40 are located closer to the bottom 35 than the stopper 37. Further, the light shielding sheet 41 is provided with cuts 42 and 43. The notch 42 and the slit 39 overlap, and the notch 43 and the slit 40 overlap.

  The strip 50 is a rectangular elongated piece, specifically, a plastic film. A strip 50 crosses the insertion hole 34. The position where the strip 50 crosses the insertion hole 34 is opposite to the opening of the insertion hole 34 with respect to the stopper 37. More specifically, the strip 50 crosses the insertion hole 34 at a position between the stopper 37 and the bottom 35. The insertion hole 34 is divided by the strip 50 into a region on the bottom 35 side and a region on the opening side.

  The strip 50 extends through the slits 39 and 40 and the cuts 42 and 43 to the outside of the cylindrical portion 36 of the jig body 31. The strip 50 is sandwiched between the portions 44 and 45 on both sides of the cut 42 and is sandwiched between the portions 46 and 47 on both sides of the cut 43. The force with which the portions 44 and 45 on both sides of the cut 42 sandwich the strip 50 is the elastic force of the light shielding sheet 41. When the strip 50 comes out of the notch 42, the notch 42 is closed by the elastic force of the light shielding sheet 41, so that light does not leak through the notch 42. When the strip 50 comes out of the notch 42, the portions 44 and 45 on both sides of the notch 42 may overlap. Even when the strip 50 is not pulled out, the cut 42 is closed by the elastic force of the light shielding sheet 41, and the gap is filled with the portions 44 and 45 on both sides of the cut 42. The same applies to the notch 43 and the portions 46 and 47 on both sides thereof.

  The strip 50 may not be passed through the notch 43 and the slit 40 but may be passed only through the notch 42 and the slit 39. In this case, the notch 43 and the slit 40 do not need to be formed.

  A first calibration target 51 and a second calibration target 52 are arranged in the insertion hole 34. The positions of the calibration targets 51 and 52 are opposite to the opening of the insertion hole 34 with respect to the stopper 37. The position of the first calibration target 51 is closer to the stopper 37 than the strip 50, and the position of the second calibration target 52 is closer to the bottom 35 than the strip 50. The first calibration target 51 is stuck to the strip 50, and the second calibration target 52 is stuck to the bottom 35 where the insertion hole 34 comes into contact. The calibration targets 51 and 52 intersect the center line of the insertion hole 34, and the calibration targets 51 and 52 and the hole 38 of the stopper 37 face each other.

  The color of the first calibration target 51 and the color of the second calibration target 52 are different. Specifically, the color of the second calibration target 52 is black, and the color of the first calibration target 51 is a color other than black (for example, white, red, green, blue, yellow, magenta, cyan, etc.). Yes, and particularly preferably, the color of the first calibration target 51 is white. The first calibration target 51 may be a uniform single color, or may be an array of various colors such as a so-called color chart.

  The first calibration target 51 is, for example, a standard color chart such as Munsell color, a standard color plate (for example, a standard white plate), a standard fluorescent sample, or a Raman standard sample. The first calibration target 51 may include a base material and a standard color sheet (for example, Munsell color sheet) attached to the base material. The first calibration target 51 may be made of barium sulfate, and preferably, the first calibration target 51 is formed by barium sulfate formed into a tablet shape. The first calibration target 51 may not be attached to the strip 50, but the strip 50 may be colored and the strip 50 may function as the first calibration target 51.

  The second calibration target 52 is preferably a material that does not reflect light or a material that has a low light reflectance. In order to prevent reflection of light at the second calibration target 52, the second calibration target 52 may be coated with an antireflection coating. The second calibration target 52 is not attached to the bottom 35 of the jig main body 31, but the bottom 35 of the jig main body 31 is colored and the bottom 35 functions as the second calibration target 52. May be.

  Either one or both of the calibration targets 51 and 52 may be a mirror. Either one or both of the calibration targets 51 and 52 may be a standard reflector (for example, Spectralon (registered trademark) of Las Sphere). When the calibration targets 51 and 52 are standard reflectors, it is preferable that the type of the standard reflector of the first calibration target 51 and the type of the reflector of the second calibration target 52 are different.

The jig body 31, the light shielding sheet 41, the strip 50, the first calibration target 51, and the second calibration target 52 preferably have chemical resistance. That is, it is preferable that the materials of the jig body 31, the light shielding sheet 41, the strip 50, the first calibration target 51, and the second calibration target 52 are materials that do not change in properties even in a sterilization gas environment. This is because the adjustment jig 30 is mainly used as a medical device.

The light shielding cover 60 has heat resistance. The property of the light shielding cover 60 does not change even under a high temperature environment.

[Storage state of probe and adjustment jig]
FIG. 6 is a perspective view illustrating a state where the probe 10 and the adjustment jig 30 are stored on the tray 70. As shown in FIGS. 5 and 6, the light projecting / receiving unit 12 of the probe 10 is inserted into the insertion hole 34, and the jig body 31 of the adjustment jig 30 covers the light projecting / receiving unit 12.
The periphery of the front end surface of the light projecting / receiving unit 12 abuts against the stopper 37 so that the light projecting / receiving unit 12 cannot be inserted any further. The front end surface of the light projecting / receiving unit 12 is separated from the calibration targets 51 and 52. The distance from the front end surface of the light projecting / receiving unit 12 to the calibration targets 51 and 52 is appropriately set by the stopper 37.

As shown in FIGS. 7 and 8, the base unit 100 includes a housing 101, a CPU 103, a RAM 104, a ROM 105, a signal processing unit 106, a photometric unit 107, light emission control units 108 and 110, an illumination light source 109, a light source 111, and an interface 112.

  A connection portion 102 is provided on the front surface of the housing 101. The connector 11 of the probe 10 is connected to the connection unit 102. When the connector 11 of the probe 10 is connected to the connection portion 102, the base end of the light projecting optical fiber 14 is connected to the light source 111 via the optical waveguide, and the base end of the light receiving optical fiber 15 is connected via the optical waveguide. Connected to the photometric unit 107, the proximal end of the illumination optical fiber 16 is connected to the illumination light source 109 via an optical waveguide.

  The sensor 113 is attached to the connection unit 102. The sensor 113 detects that the connector 11 is connected to the connection unit 102 and outputs a detection signal to the CPU 103. The sensor 113 is, for example, an infrared sensor, a micro switch, or a proximity sensor.

  The ROM 105 stores a program that can be read by the CPU 103. The CPU 103 executes a program stored in the ROM 105, controls the signal processing unit 106, the photometry unit 107, the light emission control units 108 and 110, and the interface 112 according to the program, and transfers signals and data between them.

  The CPU 103 performs calculations related to calibration according to the program, and records the calculation results (correction coefficients) in the RAM 104. The CPU 103 causes the photometry unit 107 to reflect the calculation result (correction coefficient).

  The interface 112 transfers data between the CPU 109 and the computer 114 in accordance with a command from the CPU 109. An input device (for example, a keyboard and a mouse) 115 and a display monitor 116 are connected to the computer 114.

[How to handle diagnostic packaging and operation of base unit]
The handling method of the diagnostic packaging 1 and the operation of the base unit 100 will be described.
FIG. 9 is a perspective view showing a usage state of the diagnostic packaging 1. FIG. 10 is a flowchart showing the flow of processing performed by the CPU 103 according to the program.

  First, the CPU 103 waits until a detection signal is input from the sensor 113 (step S1: No).

  At that time, the user opens the packaging bag 90 and takes out the probe 10, the adjustment jig 30, the light shielding cover 60 and the cover 80 together with the tray 70 from the packaging bag 90. Next, the user removes the cover 80 from the tray 70. Then, the user reads the identifier 26 attached to the probe 10 and inputs the same value as the identifier 26 with the input device 115. The input identifier is transferred from the computer 114 to the CPU 103, and the CPU 103 records the input identifier in the RAM 104. The input of the identifier may be omitted.

  Next, the user takes out the connector 11 of the probe 10 from the connector storage portion 73 and connects the connector 11 to the connection portion 102 of the base unit 100. Since the cable body 13 is spirally wound so that the connector 11 side of the cable body 13 overlaps the light projecting / receiving part 12 side of the cable body 13, the user can easily take out the connector 11.

  When the connector 11 is connected to the connection unit 102, the connector 11 is detected by the sensor 113, and a detection signal is output from the sensor 113 to the CPU 103. When the detection signal is input from the sensor 113 (step S1: Yes), the CPU 103 controls the light emission control unit 110 to cause the light source 111 to emit light (step S2). The excitation light emitted from the light source 111 is guided to the tip by the projecting optical fiber 14 and projected by the lens 17. The excitation light is reflected by the first calibration target 51. The reflected light is collected at the tip of the light receiving optical fiber 15 by the lens 17 and guided to the photometry unit 107 by the light receiving optical fiber 15. Since the tip of the light projecting / receiving unit 12 is located in the immediate vicinity of the first calibration target 51, excitation light and reflected light are hardly attenuated and high intensity reflected light is incident on the tip of the light receiving optical fiber 15. To do. The connection of the connector 11 may not be detected by the sensor 113. In this case, the light source 111 is always in a light emitting state, and the CPU 103 recognizes the connection of the connector 11 from the change in the measurement result of the photometry unit 107. This is because when the connector 11 is connected to the connection unit 102, the measurement result of the photometry unit 107 changes.

  Next, the CPU 103 causes the photometry unit 107 to perform photometry processing (step S3). The photometric unit 107 measures spectral data and intensity data.

  Next, the CPU 0103 performs calibration processing (step S4). Specifically, the CPU 103 determines whether or not the spectrum data and intensity data measured by the photometry unit 107 are included in an appropriate range. Further, the CPU 013 calculates a correction coefficient from both or one of spectrum data and intensity data measured by the photometry unit 107. If the color of the first calibration target 51 is white, such calibration processing is intended for white balance adjustment, and adjustment of variations based on individual differences and combinations of the probe 10, the light source 111, and the photometry unit 107. With the goal.

  Next, the CPU 103 records the determination result and the correction coefficient in step S4 in the RAM 104 (step S5). At this time, the CPU 103 records the determination result and the correction coefficient in association with the previously recorded input identifier.

  Next, the CPU 103 outputs a display command to the computer 114 via the interface 112 (step S6). Receiving the display command, the computer 114 causes the display monitor 116 to display a screen prompting the user to pull out the strip 50 from the slit 39 of the jig body 31. As a result, the next handling operation can be easily understood by the user.

  Next, the CPU 103 waits until the measurement result of the photometry unit 107 changes (step S17: No).

  On the other hand, the user pulls out the strip 50 from the jig body 31 and the light shielding sheet 41. When the strip 50 is pulled out, the first calibration target 51 is removed from the front of the light projecting / receiving unit 12 of the probe 10, and the second calibration target 52 is directly opposed to the distal end surface of the light projecting / receiving unit 12 of the probe 10. If the color of the second calibration target 52 is black, the excitation light is hardly reflected by the second calibration target 52. Even if the excitation light is slightly reflected by the second calibration target 52, the reflected light is likely to be attenuated because the distance from the tip surface of the light projecting and receiving unit 12 to the second calibration target 52 is long. Therefore, the intensity of the reflected excitation light received by the tip surface of the light projecting / receiving unit 12 of the probe 10 is very low. The light shielding cover 60 is also removed when the strip 50 is pulled out, but the light shielding cover 60 is attached to the original position after the strip 50 is pulled out.

  The measurement result of the photometric unit 107 changes when the target directly facing the tip surface of the light projecting / receiving unit 12 of the probe 10 is changed from the first calibration target 51 to the second calibration target 52. When the CPU 103 recognizes a change in the measurement result of the photometry unit 107 (step S7: Yes), the CPU 103 causes the photometry unit 107 to perform photometry processing (step S8). Thereby, spectrum data and intensity data are measured by the photometry unit 107. In this photometry, the CPU 103 may turn on the light source 111 or turn it off.

  Next, the CPU 0103 determines whether or not the spectrum data and intensity data measured by the photometry unit 107 are included in an appropriate range, and corrects from both or one of the spectrum data and intensity data measured by the photometry unit 107. A coefficient is calculated (step S9). If the color of the second calibration target 52 is black, the intensity of the reflected excitation light received at the tip of the light projecting / receiving unit 12 of the probe 10 is very low. The purpose is to grasp the intensity of stray light derived from the optical fiber 17 and the optical fibers 14 and 15 and the intensity of reflection noise.

Next, the CPU 103 records the determination result in step S9 and the correction coefficient in the RAM 104 in association with the input identifier (step S10).
Next, the CPU 103 outputs a display command to the computer 114 via the interface 112 (step S11). Receiving the display command, the computer 114 causes the display monitor 116 to display a screen indicating that the calibration process has been completed. As a result, the user can easily understand the end of the calibration process.
Then, the CPU 103 ends the process with the determination result, the correction coefficient, and the input identifier stored in the RAM 104.

  Note that the CPU 103 may control the emission controller 110 to change the wavelength of the excitation light emitted from the light source 111 after the recording process in step S5 is completed and before the display process in step S6. Thereafter, the CPU 10 sequentially performs the photometry process, the calibration process, and the recording process described above, and then performs a display process (step S6). The same applies to the case after the end of the recording process in step S10 and before the display process in step S11.

  As described above, the user handles the diagnostic packaging 1 and the processing of the CPU 103 is performed, whereby calibration is performed. When the base unit 100 has a recording medium (for example, a nonvolatile memory, a magnetic disk drive, etc.) and the processing shown in FIG. 10 is completed, the CPU 103 records the input identifier, the determination result, and the correction coefficient recorded in the RAM 104. You may record on a medium. By doing so, the input identifier, determination result, and correction coefficient for each probe 10 are accumulated in the recording medium, and it becomes easy to perform feedback such as lot management.

  When the user removes the connector 11 from the connecting portion 102 during or after the processing shown in FIG. 10, the sensor 113 detects that fact. Then, the CPU 103 deletes the input identifier, the determination result, and the correction coefficient stored in the RAM 104.

  After the calibration as described above is performed, the user peels off the light shielding cover 60 without removing the connector 11 from the connection portion 102. Then, the user takes out the light projecting / receiving unit 12 and the adjustment jig 30 of the probe 10 from the tip end storage unit 75. Further, the user pulls out the light projecting / receiving unit 12 from the insertion hole 34. Then, if necessary, the light projecting / receiving portion 12 of the probe 10 is inserted into the lumen using the forceps channel of the endoscope. At that time, the illumination light source 109 may be turned on to illuminate the periphery of the light projecting / receiving unit 12.

  Thereafter, the light source 111 is turned on by the CPU 103. If it does so, excitation light will be projected on the measurement site | part of a biological tissue from the front-end | tip of the light projection light-receiving part 12 of the probe 10 with the optical fiber 14 for projection, and the lens 17. FIG. The measurement site of the living tissue emits fluorescence due to the excitation light, and the fluorescence is received at the tip of the light projecting / receiving unit 12 of the probe 10. The received fluorescence is transmitted to the photometry unit 107 through the light receiving optical fiber 15. The CPU 103 causes the photometric unit 107 to reflect the correction coefficient recorded in the RAM 104. Then, the intensity data and spectrum data of the fluorescence received by the photometry unit 107 are measured, and the intensity data and spectrum data are corrected with a correction coefficient. The intensity data and spectrum data corrected by the correction coefficient are signal processed by the signal processing unit 106 or transferred to the computer 114 by the CPU 103 and the interface 112. The computer 114 causes the display monitor 116 to display the corrected intensity data and spectrum data. Thereby, the measurement site | part of a biological tissue can be diagnosed.

  Since the probe 10 is disposable, after the diagnosis, the connector 11 is removed from the connection portion 102 and the probe 10 is discarded. The adjustment jig 30, the strip 50, the light shielding cover 60, the tray 70, the cover 80, and the packaging bag 90 are also discarded. The adjustment jig 30 may be reused for calibration of another probe.

〔effect〕
According to the above embodiment, the following effects can be obtained.

(1) Since the probe 10 and the adjustment jig 30 are a set, it is not necessary to prepare a large-scale adjustment jig different from the adjustment jig 30.
(2) Since the probe 10 and the adjustment jig 30 are a set, the user notices the presence of the adjustment jig 30 when the packaging bag 90 is opened. Therefore, the user remembers to calibrate the probe 10 using the adjustment jig 30 before performing the fluorescence diagnosis using the probe 10.
(3) Since the probe 10 and the adjustment jig 30 are a set, the new adjustment jig 30 can be used for calibration of the probe 10. There is no deterioration, discoloration, or the like of the calibration targets 51 and 52 of the adjustment jig 30, and accurate calibration can be performed.
(4) The light projecting / receiving unit 12 is covered with the jig body 31 in advance in a state where the front end surface of the light projecting / receiving unit 12 of the probe 10 (particularly, the light projecting / receiving window 20) faces the calibration targets 51, 52. It has been broken. In particular, the distance from the front end surface of the light projecting / receiving unit 12 to the calibration targets 51 and 52 is appropriately set in advance. Therefore, it is not necessary to set the light projecting / receiving unit 12 of the probe 10 in another large-scale adjustment jig or the like during calibration. Therefore, it is convenient for the user.
(5) Since the front end surface of the light projecting / receiving unit 12 and the calibration targets 51 and 52 face each other in advance and the periphery thereof is kept light-tight, the user connects the connector 11 of the probe 10 to the connecting unit of the base unit 100. Calibration is automatically performed only by connecting to 102. For this reason, it is not necessary to require the user to perform special work / load.
(6) Since the tip of the light projecting / receiving unit 12 of the probe 10 is in contact with the stopper 37, the calibration targets 51 and 52 are shielded from light by the stopper 37. Therefore, the accuracy of calibration is high. Since the stopper 37 is provided in a ring shape, the stopper 37 does not hinder light projection and light reception.
(7) Since the calibration targets 51 and 52 and the light projecting / receiving unit 12 are shielded by the light shielding sheet 41, the calibration accuracy is high.
(8) Since the diagnostic packaging 1 is simply configured, the cost of the diagnostic packaging 1 is low.
(9) Since the calibration targets 51 and 52 are disposed in the insertion hole 34, the calibration can be performed twice.
(10) The second calibration can be performed by simply pulling out the strip 50.
(11) Since the storage of the probe 10 and the adjustment jig 30 is devised, it is easy to use. Calibration can be performed without taking out the adjustment jig 30.
(12) Since the probe 10 and the adjusting jig 30 are disposable, they are easy to use and hygienic.
(13) Since the light projecting / receiving part 12 of the probe 10 is inserted into the insertion hole 34 of the jig body 31, the light projecting / receiving part 12 is protected. In particular, the light projecting / receiving unit 12 can be further protected by the cushioning property of the light shielding sheet 41.
(14) Since the handling procedure is displayed on the display monitor 116, the calibration handling procedure can be reliably performed without making a mistake. Furthermore, the calibration is completed without allowing the user to recognize the calibration action.
