Description

Technical Field

[0001] The present invention relates to the technical field of olfactory detection, and more particularly to an olfactory detection device for rhinology. Background Art

[0002] Olfactory examinations can generally be performed through nasal endoscopy, olfactory electrophysiological examinations, and other methods. An olfactory test is usually required before the examination to evaluate the patient's olfactory function through specific odor stimulation, which helps to determine whether there is olfactory disorder. Nasal endoscopy is usually used to observe whether there are abnormal structures in the nasal cavity, whether there is congestion, edema, etc. When the patient's olfactory test results are poor, the nasal mucosa will be stimulated by electrodes. Under the action of the electrodes, the nerve sensitivity of the nasal mucosa is restored, thereby determining whether there is olfactory dysfunction in the nasal cavity.

[0003] However, when testing patients' sense of smell, most existing devices do not fully consider the differences in olfactory perception between the two nasal cavities. When performing unilateral testing using traditional methods, the odor on the side tested first will be transmitted from one nasal cavity of the patient to the other, thereby affecting the test results. Summary of the Invention

[0004] The present invention provides an olfactory detection device for nasal medicine to solve the problem in the prior art that when testing a patient's sense of smell, the odor on one side of the nasal cavity where the olfactory detection is first performed will be transmitted from one side of the patient's nasal cavity to the other side, thereby affecting the test result.

[0016] The principle and beneficial effects of this technical solution:

[0017] (1) The test component provided in the present invention can block and paralyze the other nasal cavity of the patient when performing unilateral olfactory testing on the patient. At the same time, an impeller is provided to guide the volatilized olfactory liquid vapor, thereby reducing the odor residue in the nasal cavity of the first test side and further improving the test accuracy.

At the same time, a new blocking sleeve is set on the outside of any insertion rod, and then the test nozzle and blocking sleeve are placed in the bilateral nasal cavities of the patient. The insertion rod is first heated to expand the gas inside the blocking sleeve. During the expansion of the blocking sleeve, the soft membrane will naturally tear. At the same time, heating will accelerate the release of anesthetic to quickly anesthetize the patient's unilateral nasal cavity. After the anesthesia is completed, the conversion component is adjusted and the suction pump is started. After a small amount of olfactory liquid is stored in the liquid storage tank, the motor is started to allow the odor generated by the olfactory liquid to be transmitted through the test nozzle into the patient's nasal cavity to be tested. At this time, the unilateral nasal cavity of the patient can be subjected to an olfactory test.

[0018] (2) The conversion component provided in the present invention can seal and manage the olfactory fluid, and control the amount of olfactory fluid connected to the atmosphere during each test, which can effectively reduce the volatilization of the olfactory fluid. When used in conjunction with components such as a motor, the test efficiency can also be improved simultaneously. When an olfactory test is required, the knob is turned, and the first spherical plug and the second spherical plug coaxially connected by the rotating shaft will rotate synchronously. The suction pump is started to pump the olfactory fluid into the transverse tube, and the motor is started to rotate forward. The motor will drive the impeller at its output shaft end to rotate, so that the impeller draws air from the filter plate at one end of the transverse tube to guide the olfactory fluid vapor to flow into the patient's nasal cavity.

[0026] Example:

[0027] like Figures 1 to 5 As shown, the present invention provides an olfactory detection device for nasal medicine, including a liquid storage cylinder 1 and a test assembly. The liquid storage cylinder 1 stores olfactory liquid. A pair of connecting seats 20 are provided at the top of the liquid storage cylinder 1.

The free end of the movable seat 14 is connected to a test cylinder 5 and a pair of insertion rods 16. The outer sides of the two insertion rods 16 are both provided with a blocking sleeve 7.

[0028] When multiple olfactory liquids need to be stored in the liquid storage cylinder 1, a corresponding number of branch pipes can be connected to the bottom end of the recovery pipe 21 to connect to different olfactory liquids. At the same time, a one-way valve can be set on the branch pipe to prevent contamination between different olfactory liquids. By switching different olfactory liquids with the electric control valve, olfactory tests of different smells can be performed.

[0029] like Figure 2 As shown, the blocking sleeve 7 is hollow and filled with a small amount of anesthetic. A plurality of rows of exhaust holes are provided on the outside of the blocking sleeve 7, and a soft film is provided inside the exhaust holes.

[0031] like Figure 3As shown, the control component includes a synchronization rod 11 that is slidably mounted on a movable seat 14. The two ends of the synchronization rod 11 are hinged with a first arm 10 and a second arm 19 respectively. A magnetic block 9 is provided at the free end of the first arm 10, and the magnetic block 9 is aligned with one end of the storage sleeve 13.

[0032] like Figure 3 As shown, a clamp 18 is provided at the free end of the second arm 19 , a retaining block 17 is provided inside the clamp 18 , and a pair of retaining grooves 15 are provided outside the insertion rod 16 , and the retaining blocks 17 are clamped in the retaining grooves 15 .

[0033] like Figure 1 、 Figure 4 and Figure 5 As shown, a horizontal tube 23 is provided on the inner top wall of the liquid storage cylinder 1, and a liquid storage tank 34 is connected to the outside of the horizontal tube 23. The liquid storage tank 34 is connected to the two connecting seats 20 respectively. A filter plate 27 is provided at one end of the horizontal tube 23, and a motor is connected to the inner side of the filter plate 27 through a bracket 28. The impeller 26 is coaxially connected to the output shaft end of the motor.

[0034] like Figure 1 and Figure 4 As shown, a conversion assembly is provided in the liquid storage cylinder 1, and the conversion assembly includes a recovery pipe 21 connected to the bottom end of the suction pump 24, a liquid outlet pipe 25 is provided at the free end of the horizontal pipe 23, the liquid outlet pipe 25 is connected to the suction pump 24, and a switch 2 is provided on the outside of the suction pump 24.

[0035] like Figure 4 and Figure 5 As shown, a pair of baffle rings 35 are provided in the recovery pipe 21 and the liquid outlet pipe 25, and a first spherical plug 36 and a second spherical plug 38 are rotatably clamped between the two pairs of baffle rings 35. The first spherical plug 36 and the second spherical plug 38 are both provided with liquid guide holes 37. The two liquid guide holes 37 are equal in size to the inner holes of the two pairs of baffle rings 35, and the setting directions of the two liquid guide holes 37 are at an angle of 60 degrees.

A fixing seat 33 is provided on the outside of the liquid storage cylinder 1 , and the knob 32 is rotatably clamped on the outside of the fixing seat 33 .

[0037] like Figure 5 As shown, three indicator blocks 30 are provided on the outside of the fixing seat 33, and a pointer 31 is provided on the outside of the knob 32.

The motor is started to rotate forward, and the motor will drive the impeller 26 at its output shaft end to rotate, so that the impeller 26 draws air from the filter plate 27 at one end of the horizontal pipe to guide the olfactory fluid vapor to flow into the patient's nasal cavity.

[0039] After the test is completed, turn the knob 32 to connect the liquid guide hole 37 on the second spherical plug with the recovery tube 21, and the olfactory liquid will flow back into the liquid storage cylinder 1 through the recovery tube 21. After the recovery is completed, continue to turn the knob 32 to make both liquid guide holes 37 disconnected from the olfactory liquid.

[0040] The specific usage and function of this embodiment are as follows:

[0041] The test assembly provided in the present invention can block and paralyze the nasal cavity on the other side of the patient when performing a unilateral olfactory test on the patient. At the same time, the impeller 26 is provided to guide the volatilized olfactory liquid vapor, thereby reducing the odor residue in the nasal cavity on the first test side, further improving the test accuracy. When using this device for testing, the rotating drum 3 is rotated along the annular frame 22, so that the outer side of the rotating drum 3 is moved to align with the patient's nostril in the test posture through the connecting tube 8 and the movable seat 14 connected to the telescopic rod. Then, a new test nozzle 6 is installed on the free end of the test cylinder 5, and at the same time, any insertion rod 16 is inserted. A new blocking sleeve 7 is placed on the outside, and then the test nozzle 6 and the blocking sleeve 7 are placed in the patient's bilateral nasal cavities. The insertion rod 16 is first heated to expand the gas inside the blocking sleeve 7. The expansion process of the blocking sleeve 7 will naturally tear the soft membrane. At the same time, the heating will accelerate the release of the anesthetic to quickly anesthetize the patient's unilateral nasal cavity. After the anesthesia is completed, the conversion component is adjusted and the suction pump 24 is started. After a small amount of olfactory fluid is stored in the liquid reservoir 34, the motor is started to allow the odor generated by the olfactory fluid to be transmitted to the patient's nasal cavity to be tested through the test nozzle 6. At this time, the olfactory test of the patient's unilateral nasal cavity can be performed;

[0042] After completing the unilateral olfactory test, the motor is first reversed to extract the gas in the nasal cavity on the side where the patient has completed the test as much as possible. After removing the test nozzle 6, the patient is allowed to breathe for a while to allow the patient to expel the inhaled olfactory fluid vapor as much as possible. After a period of time, the blocking sleeve 7 is placed on the other insertion rod 16 and the movable seat 14 is rotated to place the blocking sleeve 7 into the patient's tested nasal cavity. At the same time, a new test nozzle 6 is taken and installed on the free end of the test tube 5. Repeat the above steps to test the olfactory sense on the other side of the patient.
