For example, it can be set as the compound diagnostic instrument corresponding to arbitrary test items like 2 items of an auditory test and a deep tendon reflex test, or 3 and 4 items which added a pain test and a vibration test to this.

  As shown in FIG. 1 etc., the trunk | drum 11 has a longitudinal shape, and is a member which couple | bonds each part, such as the arm part 12 and the hammer head 14, integrally. The torso 11 transmits the vibration of the arm 12 to the vibration-sensing test cap 27 described later when a vibration-sensing test is performed. It also functions as a transmission unit. In general, most of the composite diagnostic instrument 10 including the body portion 11 is preferably made of aluminum (aluminum alloy) that is lightweight and has good workability, but the constituent material is not particularly limited.

  As shown in FIG. 1 and the like, the body portion 11 has a substantially cylindrical shape that is slightly narrowed toward the distal end side, and the joint portion (the end face of the distal end) with the end arm portion 12 is rounded. It has a shape with a reduced diameter. Then, three flat surfaces are formed on the side surface. The shape of the body portion 11 is not particularly limited as long as it has a longitudinal shape, and a rectangular shape, a triangular pyramid shape, a conical shape, or the like can be applied. Although the length and thickness (diameter) can be arbitrarily set as the size of the body portion 11, the length can be determined in consideration of operability in a deep tendon reflex examination using a hammer head 14 described later. preferable.

  As shown in FIG. 1 and FIG. 2, a visual acuity plate 24 for visual inspection and a pupil gauge 25 can be provided on the flat surface of the side surface of the body portion 11. Examples of the visual inspection include a visual acuity test using the visual acuity plate 24 and a pupil size inspection using the pupil gauge 25. The visual acuity plate 24 can be composed of, for example, numbers (FIG. 1) having different sizes corresponding to eight levels of visual acuity of 0.01 to 1.0, or characters and symbols having different sizes. A visual acuity test using the visual acuity plate 24 usually shows one character at a time in order from the larger number on the visual acuity plate 24 at a position away from the patient's eyes by a predetermined distance (for example, 30 cm) with one eye hidden. This is done by checking whether or not. Further, the pupil gauge 25 can be configured by a plurality of black circle displays having different sizes of about 2 to 7 mm. The examination of the pupil size using the pupil gauge 25 is an examination for measuring the size of the pupil, and enables quick measurement by the pupil gauge 25.

  As shown in FIG. 1 and the like, the arm portion 12 is a member that is provided from one end of the body portion 11 along the longitudinal direction of the body portion 11 and vibrates in response to an external force. Here, the external force means a force applied by a user (physician or the like) who performs an auditory test or the like by hitting or playing the arm portion 12 by hand. The arm portion 12 is branched into two from one end of the body portion 11 and has a shape in which two elongated plates are arranged in parallel with a gap therebetween. A weight 13 is attached to each of the two arm portions 12.

  The weight 13 has a function of adjusting the vibration frequency of the arm 12 and is detachably attached by a screw or the like. That is, if the attachment position of the weight 13 is changed, the level of vibration sound can be changed. Note that the shape and size of the weight 13 can be arbitrarily set in consideration of the adjustment of the frequency, the design, and the gripping ability when performing a deep tendon reflex examination or the like.

  As shown in FIG. 1 and the like, the composite diagnostic device 10 has a longitudinal shape as a whole by forming the body portion 11 and the arm portion 12 in a straight line. As described above, the arm portion 12 vibrates and generates a vibration sound. The body portion 11 is gripped when the arm portion 12 is vibrated, and the vibration of the arm portion 12 is applied to the vibration detection test cap 27. It has a function to communicate. That is, a tuning fork is constituted by the arm portion 12 and the body portion 11 and is used for an auditory test and a vibration sense test.

  Here, the hearing test using the tuning fork mainly includes a hearing test and a Weber test. The hearing test is a test in which the arm 12 is struck by hand to vibrate, and the vibrating arm 12 is brought closer to the patient's ear about 10 cm to check whether sound can be heard. The hearing test is performed on both the left and right ears, and it is also checked whether there is a difference in the way of hearing between the left and right. In addition, the Weber test is performed by hitting the arm 12 with a hand and vibrating it, and applying it to the frontal front midline of the pain test unit 15. At this time, if it is biased to the right, the right middle ear or the left inner ear is abnormal, and if it is biased to the left, an abnormality in the left middle ear or the right inner ear is suggested.

  The hammer head 14 corresponds to a hammer head and is a part used for deep tendon reflex examination. The deep tendon reflex examination is performed using a hammer, but in the composite diagnostic device 10, the hammer head 14, the arm portion 12, and the trunk portion 11 are integrated to function as a hammer. That is, the arm portion 12 and the body portion 11 are hammer handles, and the arm portion 12 functions as a hammer handle.

  As shown in FIG. 1 and the like, the hammer head 14 is provided at the distal end of the body part 11 and is orthogonal to the longitudinal direction of the body part 11 (substantially orthogonal). Including the direction to be stretched, and so on). Thus, by providing the hammer head 14, the arm portion 12 can be used as a handle. The shape of the hammer head 14 is not particularly limited as long as it is a shape that extends in a direction orthogonal to the longitudinal direction of the body portion 11, and may be, for example, a semicircular shape, a triangular shape, or a trapezoidal shape. May be.

  Here, the deep tendon reflex test using the hammer head 14 is a test for confirming whether the deep tendon reflex is increased or decreased by grasping the arm 12 and tapping the patient's lower knee with the hammer head 14. . In addition, when hitting with the hammer head 14, the patient is seated on a chair without a foot, or the foot is lifted by putting a hand under the thigh, etc., and the force of the foot is lost.

  The pain test unit 15 is a part used for a pain test (perception test). The pain test unit 15 includes a needle wheel 16 having a plurality of needles formed on the outer peripheral side surface thereof, and a support unit 17 (see FIG. 5) that rotatably supports the needle wheel 16. 11 is provided at the tip. As will be described in detail later, the pain test unit 15 includes a protective cover 18 that conceals and protects the needle tip of the needle wheel 16 when the pain test is not performed, a fixing screw 19 that fixes the protective cover 18, a protective cover A pin 20 and a pin hole 21 for restricting the movement of 18 are provided.

  The pain inspection unit 15 is provided along a direction orthogonal to the longitudinal direction of the body portion 11, similarly to the hammer head 14. Furthermore, it is preferable that the pain sensor 15 is provided in the direction opposite to the hammer head 14 as shown in FIG. That is, the pain sensor 15 and the hammer head 14 are provided in a straight line. According to this configuration, for example, the pain sensor 15 does not get in the way when using the hammer head 14, and the left and right balance when using the hammer head 14 and the pain sensor 15 is uniform. Therefore, the operability is improved and the design of the instrument is also good.

  Here, in the pain test using the pain test unit 15, the needle wheel 16 is rotated by applying the needle of the needle wheel to the back of the patient's hand or the like to check whether or not mild pain is felt. It is an inspection. In addition, it is preferable to change a test part according to a patient's condition. When the pain test is performed, the fixing screw 19 is tightened to the base side so that the protective cover 18 can be moved (within a range limited by the pin 20 and the pin hole 21), and the needle tip of the needle wheel 16 is protected. It is made to protrude from 18. Moreover, the arm part 12 can be utilized as a holding part (grip) similarly to the deep part tendon reflex examination.

  The light 22 can be used in the same manner as a general penlight, and is used for pupillary reflex examination and intraoral examination. Like the hammer head 14 and the like, the light 22 is provided at the front end of the body portion 11, and preferably, as shown in FIG. 1 and the like, the light 22 is provided at the end surface of the front end of the body portion 11. It faces in the direction along the longitudinal direction of the body part 11. In addition, a light switch 23 is provided that can be pushed and operated along the direction near the light 22, for example, the tip of the body portion 11 and perpendicular to the hammer head 14.

  Here, the pupil reflex examination using the light 22 is an examination in which the light 22 is turned on and the eyeball is irradiated with light at a position about 5 cm away from the face at the height of the patient's eyes to examine the expansion and contraction of the pupil. is there. Although not shown in the drawings, a dry battery is mounted on the composite diagnostic instrument 10 as a power source for the light 22. For example, the hammer head 14 can be detachably formed, and a storage part for the dry battery can be formed therein.

  As shown in FIG. 1 and the like, a thread groove is formed around the light 22 so that the light cap can be screwed on. As shown in FIG. 4, two types of light caps that cover the light 22 can be attached to the end surface of the front end of the body portion 11. The two types of light caps are both detachably mounted and function not only to cover the light 22 but also to be pressed against the test part. In the present specification, the examination part means a part of the patient's body against which the instrument is pressed when performing an examination.

  The light cap shown in FIG. 4A is a member (Babinsky reflection inspection cap 26) having a pointed tip and used for the Babinsky reflection inspection. That is, the Babinsky reflection inspection cap 26 covers the light 22 and is pressed against the sole which is the test part. Here, the Babinsky reflex test using the Babinsky reflex test cap 26 is a method in which the sharp part of the Babinsky reflex test cap 26 is pressed against the sole, which is the test part, from the heel toward the fingertip. This is an inspection for confirming whether or not the thumb is dorsiflexed. At this time, if the thumb is dorsiflexed, a positive reaction is assumed.

  The cap shown in FIG. 4B has a shape with a flat tip, and is a cap (vibration sensation inspection cap 27) used for vibration sensation inspection. That is, the vibration detection test cap 27 covers the light 22 and is pressed against the sole which is the test part. Here, the vibration sensation test using the vibration sensation test cap 27 is a method in which the flat portion of the vibration sensation test cap 27 is pressed against a rib, a shin, a heel, etc., and the arm 12 is vibrated to thereby generate vibration. This is a test to confirm whether or not you feel it.

  As described above, in the composite diagnostic instrument 10, when the pupil reflex inspection or the intraoral inspection is performed using the light 22, the light cap is removed and the state shown in FIGS. On the other hand, when performing the Babinsky reflection inspection, the Babinsky reflection inspection cap 26 is attached, and when performing the vibration sensation inspection, the vibration sensation inspection cap 27 is attached. As described above, a plurality of different inspections can be performed by changing the shape of the light cap attached to the end face of the front end of the body portion 11 or removing the light cap.

  Here, the structure of the pain test unit 15 will be described in detail with reference to FIG. FIG. 5 is an enlarged view of a portion surrounded by a dotted line in FIG. 1, where the needle tip of the needle wheel 16 protrudes from the protective cover 18 (FIG. 5A) and the needle tip of the needle wheel 16 is the protective cover 18. Shows the state of being concealed and protected (FIG. 5B). As described above, the pain test unit 15 includes the needle wheel 16 having a plurality of needles formed on the outer peripheral side surface thereof, and the support unit 17 that rotatably supports the needle wheel 16, and as shown in FIG. 17 is provided along a direction orthogonal to the longitudinal direction of the body portion 11 and in a direction opposite to the hammer head 14. The support portion 17 supports the rotational axis of the needle wheel 16 with the needle wheel 16 sandwiched from both planes. The needle tip of the needle wheel 16 protrudes outward from the support portion 17.

  The protective cover 18 has a shape in which the needle wheel 16 is sandwiched from both flat sides and the tip is opened (see FIGS. 3 and 5). The protective cover 18 is supported by the support portion 17 so as to be movable back and forth along the direction orthogonal to the longitudinal direction of the body portion 11 (along the support portion 17). A through hole is formed in the support portion 17 along the width direction (longitudinal direction of the body portion 11). Pins 20 are inserted into the through hole, and pins on both sides of the protective cover 18 along the forward / backward direction. A pin hole 21 (FIG. 3) into which 20 is fitted is formed. That is, the inner diameter of the protective cover 18 is larger than the outer diameter of the support portion 17, and the movement range is limited by the pin 20 and the pin hole 21 by being placed on the support portion 17.

  A fixing screw 19 is provided at the base of the support portion 17, and the protective cover 18 can be moved and fixed to the distal end side of the needle wheel 16 by rotating the fixing screw 19. As shown in FIG. 5 (b), both the flat surfaces of the needle wheel 16 can be completely covered and the needle tip can be concealed and protected while the protective cover 18 moves forward to the tip side of the needle wheel 16. In this state, the pin 20 is in contact with the root side end of the pin hole 21. On the other hand, in the state of FIG. 5A, the pin 20 is in contact with the end of the pin hole 21 (see FIG. 3 and the like), but the protective cover 18 is not fixed by the fixing screw 19. It can move freely within the range of the length of the pin hole 21.

  As described above, the composite diagnostic device 10 can be replaced with the tuning fork composed of the body portion 11 and the arm portion 12, the hammer head 14 provided at the tip of the body portion 11, the pain test portion 15, and the light 22. A Babinsky reflection test cap 26 and a vibration sense test cap 27, and a visual test display (sight plate 24, pupil gauge 25) provided on the side surface of the body part 11. Therefore, depending on the function of each part, multiple tests, specifically visual test, auditory test, deep tendon reflex test, pain test, pupil reflex test, vibration test, and Babinsky reflex test are performed using one instrument. It becomes possible to do.

  Further, since the hammer head 14 and the pain sensor 15 extend along a direction perpendicular to the longitudinal direction of the body 11, the arm 12 of the tuning fork can be used as a handle (gripping part), and the operation is good. Can be realized. Further, since the hammer head 14 and the pain test section 15 are formed in a straight line, when one is used, the other does not get in the way, and the balance of the instrument during use is good.

  In the above description, the replaceable Babinsky reflection inspection cap 26 and the vibration sensation inspection cap 27 that cover the light 22 have been described. However, the body portion 11 does not have the light 22 or has no relation to the light 22. It is also possible to provide an abutting portion that is pressed against the test portion fixed to the end face of the other end of the. For example, the contact portion may be a contact portion that has a flat tip shape and is used for vibration sense inspection, or a contact portion that has a sharp tip shape and is used for Babinsky reflection inspection. .
