Description

Technical Field

[0001] The present disclosure relates to the technical field of medical devices, and particularly to an olfactory ability detection device. Background Art

[0002] Olfactory tests mainly involve examining and evaluating the olfactory ability of humans. Currently, the main method for detecting olfaction in physical examination institutions is that medical staff use olfactory rods with different odors and different odor concentrations to test the subjects. This testing method is manually operated, with high labor costs for medical staff and low efficiency. Therefore, there is an urgent need for an efficient automatic detection method.

[0003] For existing olfactory detection devices, first, technologies such as barcode scanning and face recognition are used to verify the identity of the subject and input information. Then, the detection bottles are manually opened, and the odors in different olfactory test bottles are blown out from the odor liquids and sent to the subject. Finally, the recognition result of the subject is compared with the standard answer to judge the olfactory ability of the tester, and its degree of automation is relatively low.

Detailed implementation manners

[0032] In order to be able to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0033] Many specific details are set forth in the following description in order to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0034] Such as Figures 1 to 5As shown in the figure, an embodiment of the present disclosure provides an olfactory ability detection device, which includes a driving member 7, a rotating disk 3, a cover plate 2, a detection bottle 5, a face mask 1, and a connecting member 4. An opening 26 is provided on the cover plate 2, and the opening 26 penetrates through the cover plate 2 along the thickness direction of the cover plate 2. The face mask 1 is hermetically connected to the opening 26 through the connecting member 4. Specifically, one end of the connecting member 4 is hermetically connected to the face mask 1, and the other end is hermetically connected to the opening 26. The rotating disk 3 is disposed in contact with the cover plate 2, and a plurality of working positions and a non - working position are sequentially arranged on the rotating disk 3. Through holes 32 are provided at the working positions, and through holes 32 may or may not be provided at the non - working position. When through holes 32 are provided at the non - working position, the non - working position has the same function as the working position and can both install the detection bottle 5. One through hole 32 among the plurality of working positions and the non - working position does not install the detection bottle 5, and the through hole 32 without the detection bottle 5 serves as the non - working position. The purpose of setting the non - working position is that when the opening 26 on the cover plate 2 is opposite to the non - working position on the rotating disk 3, no odor will escape from the opening 26, which can be used as the shutdown state of the olfactory ability detection device. The driving member 7 is connected to the rotating disk 3 to drive the rotating disk 3 to move, so that different working positions on the rotating disk 3 are sequentially corresponding to the opening 26 on the cover plate 2, for providing odors in different detection bottles 5 to the opening 26. The number of detection bottles 5 is equal to the number of working positions, and the detection bottles 5 are installed at the through holes 32 in a one - to - one correspondence. A bottle mouth seal 11 is provided at the bottle mouth 510 of the detection bottle 5. When the bottle mouth seal 11 is not affected by an external force, it is hermetically connected to the bottle mouth 510. When the bottle mouth seal 11 is under pressure, it can be separated from the bottle mouth 510 of the detection bottle 5 to open the bottle mouth 510 of the detection bottle 5 and release the odor in the detection bottle 5. A pressing member and an upper elastic member 24 are arranged in the opening 26. The abutting member 25 is connected to the cover plate 2 through the upper elastic member 24. When one of the detection bottles 5 rotates to a position opposite to the opening 26, the abutting member 25 provides a pressure to the bottle mouth seal 11 under the action of the upper elastic member 24, thereby opening the bottle mouth 510 of the detection bottle 5. Specifically, when the bottle mouth 510 of the detection bottle 5 is not corresponding to the opening 26, the upper elastic member 24 in the opening 26 is in a compressed state. Once the bottle mouth 510 of the detection bottle 5 corresponds to the opening 26, since the bottle mouth seal 11 is movable relative to the detection bottle 5, the reaction force acting on the abutting member 25 and the upper elastic member 24 is relatively small. Therefore, the upper elastic member 24 resets and pushes the abutting member 25 to provide sufficient pressure to the bottle mouth seal 11, so that the bottle mouth seal 11 is separated from the bottle mouth 510 of the detection bottle 5 and opens the bottle mouth 510 of the detection bottle 5. This olfactory ability detection device has a high degree of automation. When the detection bottle 5 moves to other positions, due to the effect of the bottle mouth seal 11, it will be sealed again and no leakage will occur. In this way, the test subject smells a pure single odor each time, improving the accuracy of the test results.

[0035] Specifically, the driving member 7 can drive the rotating disk 3 to move linearly or drive the rotating disk 3 to rotate. When the rotating disk 3 moves linearly, multiple working positions and one empty position are arranged in sequence along the movement direction of the rotating disk 3; when the rotating disk 3 rotates, multiple working positions and one empty position are distributed in a circular array. In some embodiments of the present disclosure, the driving motor is a rotating motor that drives the rotating disk 3 to rotate. By setting the rotating disk 3 to rotate, multiple working positions and one empty position are distributed in a circular array on the rotating disk 3, which can reduce the size of the rotating disk 3 to a certain extent and reduce the overall volume of the olfactory ability detection device.

[0036] Further, in some embodiments of the present disclosure, the bottle mouth seal 11 includes a movable plug 111 and a sliding sleeve 112. The sliding sleeve 112 is fixedly arranged in the detection bottle 5, and a gas channel is provided between the sliding sleeve 112 and the inner wall of the detection bottle 5. One end of the movable plug 111 is slidably inserted into the sliding sleeve 112, and the other end is sealingly inserted into the bottle mouth 510. A lower elastic member 113 is arranged between the movable plug 111 and the sliding sleeve 112. Specifically, the outer wall of the sliding sleeve 112 is fixedly connected to the inner wall of the detection bottle 5, and a gas channel is formed therebetween, which does not affect the normal discharge of gas from the bottle mouth 510. The arrangement of the movable plug 111 allows it to move towards the inside of the detection bottle 5 when the movable plug 111 is subjected to pressure to open the bottle mouth 510. The sliding sleeve 112 provides an installation point for the movable plug 111 and can limit the movement direction of the movable plug 111 through the sliding sleeve 112, improving the stability of the overall structure. When the pressure applied to the movable plug 111 disappears, the lower elastic member 113 can reset and drive the movable plug 111 to move upward to block and seal the bottle mouth 510.

[0037] Further, the elastic force of the upper elastic member 24 is greater than the elastic force of the lower elastic member 113 to ensure that when the opening 26 faces the detection bottle 5, the abutting member 25 provides pressure to the movable plug 111 under the action of the elastic force of the upper elastic member 24, and this pressure is greater than the elastic force of the lower elastic member 113 so that the movable plug 111 can be separated from the bottle mouth 510.

[0038] In addition, in some other embodiments of the present disclosure, the bottle mouth seal 11 can also be designed as a sealing cover plate 2 hinged to the detection bottle 5. A part of the sealing cover plate 2 is hinged to the detection bottle 5 to realize the function of the sealing cover plate 2 being flip - able. When the sealing cover plate 2 receives the pressure from the abutting member 25, it can flip to open the bottle mouth 510 of the detection bottle 5. A return spring is also arranged between the sealing cover plate 2 and the detection bottle 5. When the pressure from the abutting member 25 disappears, the return spring drives the sealing cover plate 2 to flip back to be sealingly engaged with the bottle mouth 510 of the detection bottle 5 again.

[0039] Further, in some embodiments of the present disclosure, the movable plug 111 includes a stopper structure 1111, a sealing portion 1112, and a sliding member 1113 arranged in sequence along the axial direction. The sealing portion 1112 and the sliding member 1112 are located inside the test bottle 5, and the sliding member 1113 is slidably inserted into the sliding sleeve 112. The stopper structure 1111 is inserted into the bottle mouth 510, the sealing portion 1112 completely covers the bottle mouth 510, a first sealing structure 114 is provided between the sealing portion 1112 and the test bottle 5, the first sealing structure 114 is arranged around the bottle mouth 510, and the first sealing structure 114 is provided on the sealing portion 1112 or the test bottle 5. Specifically, in some embodiments of the present disclosure, the shape of the bottle mouth 510 is circular, the outer shape of the sealing portion 1112 is also circular, the diameter of the sealing portion 1112 is greater than the diameter of the bottle mouth 510, the first sealing structure 114 is an O-ring, and the diameter of the first sealing structure 114 is greater than the diameter of the bottle mouth 510 and less than the diameter of the sealing portion. The diameter of the stopper structure 1111 is less than the diameter of the bottle mouth 510. When the stopper structure 1111 is inserted into the bottle mouth 510, the upper surface of the sealing portion 1112 fits against the inner wall of the test bottle 5, and the first sealing structure 114 provides a sealing effect between the sealing portion and the bottle mouth 510 of the test bottle 5, preventing the odor inside the test bottle 5 from escaping through the bottle mouth 510.

[0040] In some other embodiments of the present disclosure, the outer shape of the sealing portion 1112 can also be designed into other shapes, as long as the area of the sealing portion 1112 is greater than the area of the bottle mouth 510 and the sealing portion 1112 can completely block the bottle mouth 510. The first sealing structure 114 can be provided on the sealing portion or on the test bottle 5. Whether it is provided on the sealing portion 1112 or on the test bottle 5, when the sealing portion 1112 blocks the bottle mouth 510, the first sealing structure 114 can achieve a sealing effect.

[0041] Further, in some embodiments of the present disclosure, one end of the lower elastic member 113 is connected to the sliding sleeve 112, and the other end is connected to the side of the sealing portion 1112 away from the bottle mouth 510. When the pressure applied to the movable plug 111 disappears, the lower elastic member 113 drives the movable plug 111 to move away from the sliding sleeve 112, thereby achieving re-blocking and sealing of the bottle mouth 510. Such a design enables the bottle mouth seal 11 to automatically block and seal the bottle mouth 510 of the test bottle 5 as long as the test bottle 5 is not located opposite the opening 26, preventing the odor from escaping and affecting the test results. It should be noted that in the embodiments of the present disclosure, both the upper elastic member and the lower elastic member are in the form of springs, deforming under pressure and returning to their original shape when the pressure disappears.

[0042] Further, in some embodiments of the present disclosure, the detection bottle 5 includes a bottle cap 51 and a bottle body 52. The bottle cap 51 is fixedly installed at the through hole 32. The inside of the bottle cap 51 is hollow. The bottle mouth 510 is provided on the bottle cap 51 and communicates with the inside of the bottle cap 51. An installation opening 511 is further provided on the bottle cap 51. The installation opening 511 is disposed opposite to the bottle mouth 510. The bottle body 52 is installed at the installation opening 511, and a second sealing structure 12 is provided between the bottle body 52 and the inner wall of the bottle cap 51. Specifically, the bottle cap 51 is cylindrical in shape. The bottle cap 51 is axially divided into a first connection section and a second connection section. The inner diameter of the first connection section is smaller than that of the second connection section. A step is formed on the inner wall of the bottle cap 51 at the connection between the first connection section and the second connection section. The installation opening 511 is formed at the end of the second connection section, and the diameter of the installation opening 511 is equal to the inner diameter of the second connection section. The bottle mouth 510 is formed at the end of the first connection section, and the diameter of the bottle mouth 510 is smaller than the inner diameter of the first connection section. The bottle cap 51 is fixedly installed at the through hole 32. Internal threads are provided on the inner wall of the second connection section, and external threads are provided on the bottle body 52, which facilitates the replacement of the bottle body 52. The second sealing structure 12 is provided at the step formed by the first connection section and the second connection section. When the bottle body 52 is screwed tightly into the second connection section, the bottle mouth 510 of the bottle body 52 abuts against the second sealing structure 12, realizing the sealed connection between the bottle body 52 and the bottle cap 51, ensuring that the odor in the bottle body 52 can only be discharged from the bottle mouth 510 of the bottle cap 51, avoiding discharge from the installation opening 511, thereby avoiding the leakage of odor during the test and further improving the accuracy of the test.

[0043] Further, in some embodiments of the present disclosure, a third seal 31 is provided between the rotating disk 3 and the cover plate 2. The third seal 31 surrounds the through hole 32 and is fixed to the rotating disk 3 or the cover plate 2, which can ensure the sealed state between the detection bottle 5 on the rotating disk 3 and the cover plate 2.

[0044] Combined Figure 3 As shown, in order to install the upper elastic member 24 and the abutting member 25, a connecting plate 23 is provided at a position on the cover plate 2 corresponding to the opening 26. The connecting plate 23 is provided on the side surface of the cover plate 2 away from the rotating disk 3, and a socket for cooperating with the connecting member 4 is provided on the connecting plate 23. The socket is disposed corresponding to the opening 26. One end of the upper elastic member 24 is connected to the connecting plate 23, and the other end is connected to the abutting member 25. The connecting plate 23 provides an installation position for the upper elastic member 24 and provides a compression force for the upper elastic member 24.

[0045] Further, in some embodiments of the present disclosure, a guiding surface is provided at one end of the abutting member 25 away from the upper elastic member 24. The guiding surface is a hemispherical surface, or the guiding surface is provided as inclined surfaces on both sides along the movement direction of the rotating disk 3. The provision of the guiding surface facilitates the up-and-down movement of the abutting member 25 under the action of a tangential force. Specifically, when the rotating disk 3 is a rotating disk, during the process of the abutting member 25 cooperating with the through hole 32 and then cooperating with another through hole 32, the abutting member 25 is subjected to a tangential force and can retract upward. When another through hole 32 of the rotating disk 3 rotates to face the opening 26, the abutting member 25 can move downward to provide pressure to the abutting member 25.

[0046] Further, in some embodiments of the present disclosure, two upper elastic members 24 are provided in each opening 26. The two upper elastic members 24 are symmetrically arranged with respect to a longitudinal section plane of the opening 26, and this longitudinal section plane is perpendicular to the tangential direction of the rotation direction of the cover plate 2. It should be noted that the number of the upper elastic members 24 can be set according to actual needs.

[0047] Further, in some embodiments of the present disclosure, a purging hole 21 is provided on the cover plate 2. The purging hole 21 is communicated with the opening 26, and the purging hole 21 is connected to a cleaning member 8 for purging the opening 26. This can prevent the residual gas in the opening 26 from affecting the test results. Specifically, in some preferred embodiments of the present disclosure, two purging holes 21 are provided on the side surface of the cover plate 2, and the cleaning member 8 is an air pump. The cleaning gas of the air pump purges the components in the opening 26 through the purging holes 21, which is convenient for quickly removing odors and reducing interference.

[0048] Furthermore, an adsorption hole 22 is also provided on the cover plate 2. The adsorption hole 22 penetrates the cover plate 2 along the thickness direction of the cover plate 2, and an active adsorption substance is filled in the adsorption hole 22. In some embodiments of the present disclosure, activated carbon adsorption cotton is filled in the adsorption hole 22 for absorbing the possible overflowing odors. The position of the adsorption hole 22 is opposite to the position of the detection bottle 5 on the rotating disk 3. The distance between the adsorption hole 22 and the opening 26 is equal to the distance between two adjacent through holes 32 on the rotating disk 3, and the adsorption hole 22 and the opening 26 are simultaneously opposite to two adjacent working positions, or the adsorption hole 22 and the opening 26 are simultaneously opposite to the empty position and an adjacent working position; to ensure that when the rotating disk 3 rotates to face the opening 26 at the next working position, the adsorption hole 22 is exactly opposite to the detection bottle 5 at the previous working position for adsorbing the possible overflowing odors from the previous detection bottle 5.

[0049] Further, in some embodiments of the present disclosure, a heater 6 is further provided on the detection bottle 5. The interior of the detection bottle 5 is heated by the heater 6 to accelerate the overflow of the odor inside the detection bottle 5, so that the odor can diffuse out quickly. Specifically, the heater 6 can be set as a heating resistor, and the detection bottle 5 can be heated by heating. The substance in the detection bottle 5 can be liquid, solid or gas, and the volatilization speed is faster when heated.

[0050] Further, in some embodiments of the present disclosure, the olfactory ability detection device further includes a support frame 9. The support frame 9 is inclined and arranged on the ground. The cover plate 2 is fixedly connected to the upper end of the support frame 9, and the cover plate 2 also remains inclined for the convenience of use by the test subject. The driving machine is fixedly arranged on the support frame 9 and is connected to the rotating disk 3.

[0051] Specifically, in some preferred embodiments of the present disclosure, the support frame 9 is fixed to the ground to support the entire device. The included angle between the support frame 9 and the ground is 30° to 60°, which is convenient for the interaction between the test subject and the test device. The support frame 9 fixes the cover plate 2. An opening 26 for releasing the odor and an adsorption hole 22 for adsorbing the overflowing odor are provided on the cover plate 2. The mask 1 is inserted into the opening 26 through the connecting member 4. The test subject places the nose on the mask 1 to smell the odor released therefrom. The rotating disk 3 is fixed on the driving member 7, and the driving member 7 is a motor and is supported by the support frame 9; one side of the rotating disk 3 is closely attached to one side of the cover plate 2. Twenty-one through holes 32 are provided on the rotating disk 3, and a third seal 31 is installed around each through hole 32, which can ensure that the detection bottle 5 and the cover plate 2 are in a sealed state. One of the through holes 32 is "sealed" and used as a neutral gear, and the remaining 20 through holes 32 are fixed with bottle caps 51. Each bottle cap 51 is hermetically connected to a bottle body 52, and the bottle body 52 contains an odor substance, which can be liquid, solid or gas.

[0052] In the olfactory ability detection device provided by the embodiments of the present disclosure, an opening is provided on the cover plate. The mask is hermetically connected to the opening through the connecting member. The driving member drives the rotating disk to move, so that different working positions are sequentially opposite to the opening. When a working position is opposite to the opening, the bottle mouth of the detection bottle installed at this working position corresponds to the opening. The bottle mouth of the detection bottle is opened, and the odor in the detection bottle is discharged from the bottle mouth and the opening, and enters the mask through the connecting member. At this time, the detection bottles at other positions are in a sealed state and will not leak, so that the test subject smells a single odor each time, improving the accuracy of the test results. During the movement of the rotating disk, whenever a detection bottle is opposite to the opening, the bottle mouth of the detection bottle opposite to the opening can be automatically opened without manual operation, and the degree of automation is high. When the detection bottle moves to other positions, it will be sealed again and will not leak. In this way, the test subject smells a pure single odor each time, improving the accuracy of the test results.

[0053] It should be noted that in this text, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the said element.

[0054] The above are only specific embodiments of the present disclosure, enabling those skilled in the art to understand or implement the present disclosure.
