Description

Olfactory threshold and false-positive self-test device with the methods of olfactory threshold and false-positive self-te}

The present invention relates to an olfactory threshold and a false positive test device and an examination method, and more specifically, to evaluate olfactory function of a general or olfactory disorder patient, to evaluate olfactory state before training, and to confirm treatment results after treatment It relates to an olfactory threshold and false positive self-testing device that can be used for evaluation, and an olfactory threshold and false positive self-testing method using the device.

The sense of smell plays a very important role in maintaining and maintaining quality of life in everyday life. Losing sense of smell reduces appetite, reduces food intake, and limits social life. The causes of olfactory mechanism and olfactory disorders include sinus diseases, rhinitis, upper respiratory tract infections, trauma, drugs, and congenital causes. Patients with brain damage due to traffic accidents, strokes, etc., patients with senile depression, dementia or Parkinson's disease It has been published for a long time that the first thing they heard was a problem with their sense of smell, so they couldn't distinguish the odor they had in their daily lives. In addition, since the functions of the olfactory organs are closely related to dementia, Parkinson's disease, depression, etc., it is very important to train the function of the olfactory organs so that they do not deteriorate.

On the other hand, in the study of hummel and others, the fact that'Olfactory training', a practice of continuously and repeatedly taking various scents alternately in patients with loss of smell or complaining of hypo olfactory syndrome, helps recovery of smell. It is well known by. To this end, it is necessary to evaluate the patient's sense of smell before olfactory training and to confirm the outcome of treatment after treatment.

Currently, the Korean version of Sniffin Stick Test (KVSS) and Butanol Threshold Test (BTT) are used as tests for olfactory thresholds in clinical practice. KVSS is a test that finds pens containing butanol by placing 3 pens in random order, and performs the test by dividing the total butanol concentration into 16 levels. BTT is a test to find a butanol container by presenting to a patient a container containing butanol solution and a test container containing only mineral oil as a control solution. The test is also conducted using a dilute solution of butanol from step 12 from the original solution.

These threshold tests require a lot of time for about one hour to perform a single test because a complicated test is required to perform and interpret, and a specialized tester is also required. In addition, the tools necessary for the test are also large and difficult to carry. In the case of BTT, it is necessary to prepare a solution, so it is necessary to visit a hospital for the test. This can cause a lot of discomfort to both the examiner and the patient. Accordingly, there is a need to develop a test device that is more convenient and portable, and can perform self-examination without an examiner, so that a patient can perform the examination anywhere and check the results without having to visit the hospital.

The housing unit 300 may be configured such that the lower housing 310, the side housing 320, and the upper housing 330 having the above-described configuration are detachably attached to each other. That is, the lower portion of the through-cylindrical member of the side housing 320 is fitted to the outside of the protruding extension member 312 of the lower housing 310 and the vertical extension member 332 of the upper housing 330 outside the upper end of the through-cylindrical member ) Is inserted so that the housing unit 300 has a height higher than that of the capsule unit 100 as a whole and can form a cylindrical shape with a closed space formed therein.

The fragrance discharging unit 400 is installed to constitute a part of the upper surface of the closed space included in the housing unit 300 and discharges the fragrance contained in the specific capsule unit 110 moved to a certain position by the moving unit 200 for a predetermined time. It is a component. As an embodiment, the fragrance discharging unit 400 may include a through hole 410, a cover part 420, and a hollow protrusion 430.

The through-hole part 410 is a hole formed through the upper housing 330 of the housing unit forming the inner space of the housing unit 300, that is, the upper surface of the closed space, and smells the fragrance contained in the capsule part 110 installed in the closed space. It is a component that discharges to the outside. Therefore, the through-hole portion 410, as shown in Figures 1a to 1c, any one of the region opposite to any one of the plurality of capsule portion 110 installed in a closed space in the disk member 331 of the upper housing 330 It may be formed by penetrating an area. Since the fragrance contained in the capsule part 110 is discharged to the outside through the through-hole part 410, the size of the through-hole part 410 may be formed to be the same as the diameter of the capsule part 110 so that the emitted fragrance is discharged to the outside. have.

The cover part 420 is a component that acts as a lid that opens or closes a closed space by opening and closing the through-hole part 410, and one side of the outer periphery of the through-hole part 410 with a diameter that can cover the through-hole part 410 from the top. It may be integrally formed on the disk member 331. The cover portion 420 may be applied to all known methods without limitation of material and shape as long as the through-hole portion 410 can be opened and closed. As an example, the diameter of the through-hole portion 410 may be inserted. A form in which the protrusions are formed and a method of manually opening and closing them may be proposed. Of course, if necessary, an automatic opening/closing cover portion 420 may be installed. Through the cover portion 420 of this configuration, when the examinee does not use the olfactory threshold and false positive self-examination device 1, the closed space is closed by covering the through hole 410 with the cover portion 420, and the olfactory threshold and false positive In the case of using the self-inspection device 1 to open the closed space by opening the cover 420, the fragrance emitted by the control unit is discharged from the capsule unit 110 when the cover unit 420 is opened. It can be diverted outside the space.

The hollow protrusion 430 is a component for assisting the fragrance emitted from the capsule 110 to be discharged almost through the through-hole 410 without being scattered elsewhere, and as shown in FIG. 1B, the through-hole ( It may be formed to form a cylindrical hollow portion having the same diameter as the through-hole portion 410 vertically downward from the outer periphery of 410). In particular, the hollow protrusion 430 may be formed to have a length maintaining an ultra close distance to the upper end of the capsule 110, as shown in Figure 1c. Hereinafter, the term "super close distance" is a distance between the lower end of the hollow protrusion 430 and the upper end of the capsule 110, but does not cause friction when the capsule 110 is moved by the moving unit 200. It means the smallest ultra-fine distance. Thus, in the case of having a "super close distance", it may be visually seen as almost in contact, but in practice, it may be formed to have a distance of several hundreds of micrometers from several nanometers.

The control unit is built in the housing unit 300 and controls one or more of the capsule unit 100, the mobile unit 200, and the fragrance discharging unit 400 to be inspected through the fragrance discharging unit 400 according to a predetermined olfactory inspection protocol. As a component that controls the olfactory threshold and the operation of the false positive self-inspection device 1 so as to discharge the scent that can be smelled, any known control unit technology can be used, but as an example, a memory, an auxiliary circuit, and The form in which the ultra-compact processing unit (MPU) is assembled on one printed circuit board may be built into the housing unit 300 and used. The control unit controls the capsule unit 100, the mobile unit 200, and the fragrance discharging unit 400 according to a predetermined olfactory test protocol program when the power of the olfactory threshold and false positive self-inspection device 1 is turned on. The concentration of the fragrance emitted from the fragrance material 113 stored in the capsule 110 is divided into at least 5 to 16 steps from the weakest concentration step to the strongest concentration step, and the fragrance discharging unit is set at a predetermined concentration in a predetermined olfactory test sequence. Through 400, the scent that can be taken by the testee is discharged, and after the scent is discharged, one or more of olfactory threshold test result information and false positive test result information may be generated according to input information selected. On the other hand, when the proximity sensor unit is included, it is possible to evaluate whether the user performed the olfactory test more accurately by comparing the nth number of times determined in the selected olfactory test protocol with the number of times the testee smelled the fragrance discharged through the fragrance discharging unit. That is, the number of times the inspected person smells the scent discharged through the fragrance discharging unit is the number of times the proximity sensor unit detects that the face of the examinee is adjacent to the fragrance discharging unit, so the number of fragrance discharge actually discharged through the fragrance discharging unit It is because there is no choice but to become the following.

The communication unit (not shown) transmits olfactory test information, that is, olfactory threshold test result information and false positive test result information, to a hospital server accessible to the inspected physician, and various related to olfactory tests including feedback information from the attending physician. As a component for receiving information, it is installed and installed in the housing unit 300. The communication unit may use any known configuration without limiting wired/wireless communication, but as one embodiment, the olfactory threshold and false positive self-inspection device 1 In the case of direct transmission to an external hospital server, a communication unit may be implemented to enable communication with an external system in the form of HTTP (hypertext transfer protocol)/REST (Representational State Transfer)/ SOAP (Simple Object Access Protocol).

The proximity sensor unit (not shown) is a component for confirming whether or not the testee actually performs olfactory testing using the olfactory threshold and the false positive self-testing apparatus 1, and the fragrance discharging unit 400, particularly the through hole 410 Adjacent to the upper housing unit 330 may be installed on the outer side. The proximity sensor unit can apply all known sensing techniques as long as it can detect that the subject's face is facing the through hole 410, but may be a proximity sensor as an embodiment.

Next, the configuration of the olfactory threshold and false positive self-inspection apparatus according to the second embodiment of the present invention will be described with reference to FIGS. 2A to 2C and 4 to 6. Figure 2a is an exploded perspective view of the olfactory threshold and false positive self-testing device according to another embodiment of the present invention, Figure 2b is a schematic perspective view showing the interior of the upper housing 330 shown in Figure 2a, Figure 2c is Figure 2a It is a schematic diagram showing the arrangement state of the fragrance discharging unit and the capsule member in a state in which the olfactory threshold and the false positive self-testing device shown in FIG. On the other hand, the configuration of the olfactory threshold and false positive self-inspection apparatus according to the second embodiment of the present invention is different from the configuration of the first embodiment described above and the configuration of the fragrance discharging unit 400, and the rest of the components are the same, thus discharging the fragrance The unit 400 will be described only for the configuration.

The fragrance discharging unit 400 is installed to constitute a part of the upper surface of the closed space included in the housing unit 300 and discharges the fragrance contained in the specific capsule unit 110 moved to a certain position by the moving unit 200 for a predetermined time. It is a component. As another embodiment, the fragrance discharging unit 400 may include a through-hole portion 410, a cover portion 420, and a moving guide portion 440. Here, since the configuration of the through-hole portion 410 and the cover portion 420 among the components of the fragrance discharging unit 400 is also the same as that of the first embodiment described above, only the moving guide portion 440 will be described in detail.

The moving guide part 440 is also a component for assisting in such that the fragrance emitted from the capsule part 110, like the hollow protrusion part 430, is almost always discharged through the through hole part 410 without being scattered elsewhere. A fixed member having a disk-shaped plate structure 441 inserted into a lower surface of the closed space as shown in 2b and fixed to the upper portion of the rotating shaft member 221 of the mobile unit 200 at the center of the plate-shaped structure 441 ( 442) is formed and has a structure in which a plurality of through-holes 443 are formed by penetrating through the plate-shaped structure 441 so that the upper ends of the capsules 110 are inserted at positions facing each of the plurality of capsules 110 installed. Can be.

Here, the diameter of the plate-shaped structure 441 is smaller than the diameter of the upper housing 330, but may have a diameter capable of covering the area where all the capsules 110 included in the capsule unit 100 are installed. If necessary, the diameter of the plate-shaped structure 441 may be formed to a diameter capable of maintaining a super close distance from the upper housing 330. The thickness of the plate-shaped structure 441 may be adjusted in consideration of the height of the rotating shaft member 221. In the state in which the plate-shaped structure 441 is fixedly installed through the fixing member 442 on the rotating shaft member 221, the upper housing 330 ) May be formed to a thickness capable of maintaining a super close distance to the inner surface of the disk member 331.

The fixing member 442 is not limited as long as it is formed at the center of the plate-shaped structure 441 and can be fixed with the rotating shaft member 221, but as an embodiment, the diameter of the upper portion of the rotating shaft member 221 can be fitted by interference fit. It can be implemented as a fixed groove.

The through-insertion hole 443 is a through-hole formed at a position facing the seating groove 211 formed in the bottom plate portion 210 toward the edge of the plate-shaped structure 441, the diameter of which can be inserted into the capsule portion 110 Diameter.

The movement guide part 440 configured as described above is fixed to the upper portion of the rotating shaft member 221 by the fixing member 442, as shown in FIG. 6, and is installed in a state spaced apart from the upper housing 330 at a very close distance. The moving unit 200 may guide the movement of the fragrance discharging unit 400 without friction so that the upper portion of the capsule portion 110 is positioned below the through hole portion 410.

Next, the configuration of the olfactory threshold and false positive self-inspection apparatus according to the third embodiment of the present invention will be described with reference to FIGS. 3A to 3C and 4 to 5C. Figure 3a is an exploded perspective view of the olfactory threshold and false positive self-testing device according to another embodiment of the present invention, Figure 3b is a schematic perspective view showing the interior of the upper housing 330 shown in Figure 3a, Figure 3c is a It is a schematic diagram showing the arrangement state of the fragrance discharging unit and the capsule member in a state in which the olfactory threshold and the false positive self-testing device shown in 3a are combined. On the other hand, the configuration of the olfactory threshold and false positive self-inspection apparatus according to the third embodiment of the present invention is different from the configuration of the first embodiment and the configuration of the fragrance discharging unit 400 in the same manner as in the second embodiment described above. Since the components are the same, the fragrance discharging unit 400 will be described only for the configuration.

The fragrance discharging unit 400 is installed to constitute a part of the upper surface of the closed space included in the housing unit 300 and discharges the fragrance contained in the specific capsule unit 110 moved to a certain position by the moving unit 200 for a predetermined time. It is a component. As another embodiment, the fragrance discharging unit 400 may include a through-hole portion 410, a cover portion 420, and a double bulkhead guide portion 440. Here, since the configuration of the through-hole portion 410 and the cover portion 420 among the components of the fragrance discharging unit 400 is also the same as that of the first embodiment described above, only the double bulkhead guide portion 450 will be described in detail.

 The double bulkhead guide part 450 also has the same scent emitted from the capsule part 110 as the hollow protrusion part 430 and the moving guide part 440 without being scattered elsewhere, and is almost always discharged through the through hole part 410. As a component for assisting, as shown in FIG. 3B, a plurality of capsules 110 seated in the seating groove 211 of the bottom plate part 210 among the upper housing 330, especially the lower surface of the disk member 331, It may be configured to include an inner partition wall portion 451 and an outer partition wall portion 452 that are spaced apart from each other so as to have a width in which the capsule portions 110 can be inserted vertically at opposite positions and extend to a predetermined length.

As described above, when the fragrance discharging unit 400 includes the double bulkhead guide part 450, a plurality of spaces between the inner part of the double bulkhead guide part 450, that is, the inner partition part 451 and the outer partition part 452, are provided. Since the upper end of the capsule portion 110 of the upper housing 330 should be inserted in a state maintaining an ultra close distance to the lower surface of the disc member 331, the height of the side housing 320 is the disc member 331 The lower surface and the upper end of the capsule can be adjusted to maintain an ultra close distance. When configured in this way, the double bulkhead guide portion 450 may guide the specific capsule portion by the moving unit 200 to move without friction when moving such that it is located in the through hole portion 410 of the fragrance discharging unit 400.

Although not specifically described, the olfactory threshold and false positive self-inspection apparatus 1 having the above-described configuration is not a wired cord type of a known method, but a housing unit 300 in order to easily use power in a home as well as a hospital. The battery can be built in and used as a portable device.

Next, looking at the olfactory threshold and the olfactory threshold testing method according to the present invention using the olfactory threshold and false positive self-testing device having the above-described configuration, as shown in FIG. 7, the basic evaluation stage, the resting stage, the primary evaluation It may include a step, a second evaluation step and a third evaluation step.

First, the basic evaluation step is a step of evaluating whether the highest concentration of butanol scent is discharged for several seconds to tens of seconds from the capsule unit containing the butanol, and whether the inspected person can detect the emitted fragrance. Since the strongest scent is discharged in this step, if the subject cannot detect the scent discharged in this step, there is a high probability that there is a problem with the olfactory function or that the testee is making a false choice. Therefore, if the test subject does not detect the fragrance discharged in the basic evaluation step, there is no need to perform the subsequent step, so the test can be terminated and one or more of the olfactory false positive test and the olfactory identification test can be performed. The resting step is a step for avoiding acclimatization of the subject exposed to a very strong butanol scent in the basic evaluation step, and may wait 2 minutes to 5 minutes as an embodiment to wait without discharging the fragrance.

The first evaluation step is a step of performing at least one of the first sensing step, the resting phase, and the second sensing step. If the sense of smell is sensitive, the threshold value can be obtained only by the first evaluation step, but if the sense of smell is not sensitive, Since the olfactory threshold result cannot be obtained only by the first evaluation step, the second and third evaluation steps may be sequentially performed.

Here, in the first sensing step, the fragrance adjusted to the nth concentration, which is the lowest concentration, is discharged for several seconds to tens of seconds, respectively, from the three capsules each containing butanol, optional fragrance material 1, and optional fragrance material 2, respectively, and discharged. As a step in which the capsule part having the butanol fragrance is selected by the testee who sequentially took the scent, the n concentration is the weakest in the first detection step performed in the first detection step when the concentration of the fragrance is controlled in 16 steps as an embodiment. It may mean the concentration adjusted to the sixteenth step with fragrance. Therefore, in the basic evaluation step, the fragrance adjusted to the concentration of the highest concentration in step 1 is discharged, and in the first evaluation step performed first, the fragrance adjusted to the concentration of 16 levels, which is the weakest concentration in the first detection step. Can be discharged. The resting step is to avoid acclimatization of the subject's sense of smell and is performed by resting for several seconds to tens of seconds. The second detection step is a step in which the first detection step is performed again as it is after the rest step is performed.

The second evaluation step is performed in the first detection step and the second detection step according to the result of selection of the butanol capsule portion of the test subject obtained in at least one of the first detection step and the second detection step performed in the first evaluation step as described above. If all are correct, the threshold test is terminated, or if any of the first and second sensing steps is wrong, at least one of the first sensing step and the second sensing step is performed with the fragrance adjusted to a concentration two levels higher than the current concentration. It is a step.

As an example, if the capsule part containing butanol is selected in the first sensing step during the first evaluation step, and the capsule part containing butanol is also selected in the second sensing step performed after the resting step, the threshold test is ended and 16 points are tested. It can be determined by the olfactory threshold.

However, if any one of the first and second sensing steps is wrong, the first and second sensing steps may be performed in the same manner as described above, with the fragrance adjusted to a concentration two levels higher than the current concentration discharged.

For example, in the first evaluation step, the test subject could not select the butanol capsule part in the first sensing step performed with the fragrance adjusted to the concentration of 16 steps, or the test subject selected the butanol capsule part in the first sensing step. In the second sensing step, if it cannot be selected, the first sensing step is performed again with the fragrance adjusted to the concentration of 14 steps discharged.

The third evaluation step is based on the result of the selection of the butanol capsule part of the test subject obtained in at least one of the first detection step and the second detection step in which the fragrance adjusted to the high concentration in the second step in the second evaluation step is discharged, If both the first sensing step and the second sensing step are correct, at least one of the first sensing step and the second sensing step is performed or the first sensing is performed with the fragrance adjusted to a concentration that is one level lower than the discharged current concentration. If any one of the steps and the second sensing step is wrong, it is a step of performing at least one of the first sensing step and the second sensing step in a state in which the fragrance adjusted to a concentration two levels higher than the current concentration is discharged.

For example, if the test subject selects the butanol capsule part in the first sensing step performed with the fragrance adjusted to the concentration of step 14, and in the second sensing step performed after the resting step, the test subject selects the butanol capsule part. The first sensing step can be performed again with the fragrance adjusted to 15 steps, one level lower than the current concentration (14-step concentration) discharged. At this time, if the test subject selects the butanol capsule part, it is 15 steps after the resting step. A second detection step may be performed at a concentration.

However, in the first sensing step performed with the fragrance adjusted to the concentration of step 14 discharged, the test subject cannot select the butanol capsule part, or in the first sensing step adjusted to the concentration of step 14, the test subject selects the butanol capsule part. However, in the second sensing step performed after the resting step, if the correct selection is not made, the first sensing step is performed again with the fragrance adjusted to the concentration of 12 steps, which is a concentration two steps higher than the current concentration (the concentration of 14 steps). Is done.

Therefore, in the above-described third evaluation step, the result of the selection of the butanol capsule part of the test subject obtained when the first detection step and the second detection step are performed with at least seven turning points or the fragrance adjusted to the nth concentration is discharged. It can be repeated several times until all fit. The terms n-th evaluation step, n-1st evaluation step, n+1st evaluation step, 4th evaluation step, 5th evaluation step, etc., used in the following are all based on the above-mentioned criteria until 7 turning points occur. This refers to the step in which the primary evaluation step is repeatedly performed, and is differently named for convenience of classification.

Here, the turning point is based on the n-th evaluation step, the concentration of the fragrance discharged in the first and second detection steps of the n-1th evaluation step, which is earlier, the fragrance discharged in the first and second detection steps of the n-th evaluation step When the concentration is lower than the concentration of the fragrance discharged in the first and second sensing steps of the n+1st evaluation step is lower than the concentration of the fragrance discharged in the first and 2 detection steps of the nth evaluation step, and n- When the concentration of the fragrance discharged in the first and second detection steps of the first evaluation step is higher than the concentration of the fragrance discharged in the first and second detection steps of the nth evaluation step, the first and second n+1 evaluation steps and When the concentration of the fragrance discharged in the second detection step is higher than the concentration of the fragrance discharged in the first and second detection steps of the n-th evaluation step, and when such conditions are met, the inflection point that occurs naturally in the n-th evaluation step is determined. it means.

For example, assuming that the nth evaluation step is the fourth evaluation step (the third evaluation step is repeated once), the n-1th evaluation step means the third evaluation step, and the n+1st evaluation step is As it means the 5th evaluation step (the 3rd evaluation step is repeated twice), as described above, the case where the concentration of the fragrance discharged in the 1st and 2nd detection steps of the 3rd evaluation step is the 15th step The first detection step 1 of the evaluation step may be defined, and the case of the 12th step may be defined as the first detection step 2 of the third evaluation step.

Therefore, the concentration of the fragrance discharged from the first and second sensing stages in the fourth evaluation stage is the first detection stage 1 in the third evaluation stage, i.e., in the 15th stage, in the first detection stage and in the second detection stage, the subjects are both If the butanol capsule part is selected, that is, if it is all matched, it becomes the 16th step, and if any of them are wrong, it becomes the 13th step. If everything is matched in the steps, it becomes the 13th step, and if any of them is wrong, it becomes the 10th step.

In addition, if the concentration of the fragrance discharged in the first and second sensing steps of the fifth evaluation step is matched with the concentration of the fragrance discharged in the first and second sensing steps of the fourth evaluation step, the sixteenth step The test is terminated because the concentrations of are continuously set, and if any one of them is wrong, it becomes the 14th step. On the other hand, if the concentration of the fragrance discharged in the first and second detection steps of the 5th evaluation step is the concentration of the fragrance discharged in the first and second detection steps of the 4th evaluation step is the 13th step, it is 14 steps. And if any one is wrong, it becomes the eleventh step. In addition, if the concentration of the fragrances discharged in the first and second sensing steps of the 5th evaluation step is 10th, if the concentrations of the fragrances discharged in the first and second sensing steps of the 4th evaluation step are all matched, the 11th step If any one is wrong, it becomes the eighth step.

Thus, as an example, looking at the case where the fourth evaluation step is a turning point, as described above, when the concentration of the fragrance discharged in the fourth evaluation step is the thirteenth step, the concentration of the fragrance discharged in the third evaluation step is removed. In the case of the 15th stage and the concentration of the fragrance discharged in the 5th evaluation stage is the 14th or 15th stage, the 4th evaluation stage becomes the turning point, and the score is given 13 points, the concentration of the fragrance discharged in the 4th evaluation stage. can do.

In addition, when the concentration of the fragrance discharged in the 4th evaluation step is the 10th step, the concentration of the fragrance discharged in the 3rd evaluation step is the 12th step, and the concentration of the fragrance discharged in the 5th evaluation step is the 15th, 14th In the case of the step or the eleventh step, the fourth evaluation step is the turning point, and the score can be given 10 points, which is the concentration of the fragrance discharged in the fourth evaluation step.

In the above-described embodiment, an example is given only when the concentration of the fragrance discharged in the third evaluation step, which is the n-1st evaluation step, is higher than the concentration of the fragrance discharged in the fourth evaluation step, which is the n-th evaluation step, but in the low case, n In the same way, it can be predicted that the inflection point generated in the n-th evaluation step is a turning point only when the concentration of the fragrance discharged in the +1st evaluation step is higher than the n-th evaluation step.

By calculating the turning point in this way, at least seven turning points are generated, or the subject obtained when the first sensing step and the second sensing step are performed with the fragrance adjusted to the nth concentration, that is, the concentration of the 16th step is performed. The third evaluation step is repeated several times until the selection results of the butanol capsules are all correct.

As an example, as shown in Table 1 below, the test subject's threshold may be determined by an average of four scores obtained later among seven scores.

density One 2 3 4 5 6 II① II③ 7 II② II II⑦ 8 - - II II⑤ 9 II -⑥ 10 - -④ 11 12 - 13 14 - 15 16 -

II: correct answer,-: incorrect answer,

Score = {10(④)+8(⑤)+9(⑥)+7(⑦)}/4= 8.5

Furthermore, equipment and methods for evaluating the presence or absence of a false reaction are needed when patients show malingering due to secondary benefits.

The present invention can provide a method for testing olfactory inclination that can identify faint disease, leprosy, and pathogenesis using the olfactory threshold and false positive self-testing device having the above-described configuration. Can be used. First, the patient who is unable to smell is a patient with true olfactory loss, having an abnormality in the first cranial nerve and olfactory nerve. However, since the fifth brain nerve is normal in patients with true olfactory loss of the olfactory nerve, even if there is an abnormality in the first brain nerve olfactory nerve, the smell of ammonia controlled by the trigerminal nerve, the fifth brain nerve, etc. Can take on. By using this, if the patient smells strong concentrations of coffee flavor (sensory nerve jurisdiction) and ammonia flavor (trigeminal nerve jurisdiction) that are familiar to the patient, patients with true olfactory loss cannot smell coffee but can smell ammonia. Or, a patient who is a soldier will state that he cannot smell both coffee and ammonia.

Accordingly, the olfactory false positive test method according to the present invention using the olfactory threshold and false positive self-examination device having the above-described configuration comprises the steps of discharging coffee and ammonia scent from two capsules each storing coffee and ammonia; Inputting a response of an examinee about whether the discharged fragrance is detected; And evaluating false positives of the sense of smell of the examinee according to the response of the examinee.

Here, the step of evaluating false positives, as shown in FIG. 8, when the test subject's answer is input as detecting both scents, the sense of smell of the testee is determined to be normal, and if it is input that it does not detect both scents, the testee Is judged to have false positives, and if it is input that only ammonia scent is detected, it is determined that the patient has lost true scent.

In addition, through the device of the present invention, an identification test can also be performed, and the olfactory identification test according to the present invention is a test capable of simultaneously determining the degree of olfactory residual ability and false positives of the patient. The test is to identify the odor presented only once by presenting a total of three odors, one for one and the other two. In the case of conducting about 15 times with different odors, those with good residual olfactory capacity will have a greater number of identifications, and those who cannot smell because they have no smell at all will be given statistically rather than 0 times. You will guess about 5 times, which is about 1/3. Using this, it can be seen that a person who matches 0 times is a person who has a very high possibility of malingering.

The present invention has been shown and described with reference to preferred embodiments as described above, but is not limited to the above-described embodiments and is within the scope of the present invention to those skilled in the art to which the present invention pertains.
