An olfactory training device

Abstract

This invention belongs to the field of medical device technology, specifically disclosing an olfactory training device. By setting the number of olfactory sticks to at least two, each olfactory stick is movably installed in the first receiving cavity of the housing. When an external force drives any olfactory stick to move, if the release end of the olfactory stick moves to the first opening, it can be used for olfactory training by the patient. After the patient completes the olfactory training with this olfactory stick, the external force retracts the olfactory stick into the first receiving cavity, and then the other olfactory sticks can be moved. Compared with the existing solution where a single odor pen can only train one odor, the olfactory training device using this structure can train at least two odors, improving the practicality of the olfactory training device.

Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to an olfactory training device. Background Technology

[0002] The sense of smell plays a vital role in social interactions and daily life. Olfactory disorders can affect quality of life, social interactions, nutrient intake, and even threaten life. Clinically, olfactory disorders are mainly classified into the following nine types according to their etiology: olfactory disorders related to rhinosinusitis, olfactory disorders following upper respiratory tract infections (URTIs), traumatic olfactory disorders, congenital olfactory disorders, age-related olfactory disorders, olfactory disorders related to nervous system diseases, olfactory disorders caused by toxins / drugs, olfactory disorders caused by other etiologies (such as olfactory disorders caused by nasal skull base surgery, tumors, etc.), and idiopathic olfactory disorders (olfactory disorders without a clearly known cause). Clinically, only a small percentage of patients with olfactory disorders receive accurate diagnosis and effective treatment.

[0003] Existing treatments for olfactory disorders include etiological treatment, drug therapy, surgical treatment, olfactory training, and other therapies. Olfactory training involves patients actively and repeatedly inhaling various types of odorants to improve their olfactory function. Equipment used for olfactory training includes scent bottles and scent pens. Current scent pens are scented felt-tip pens consisting of a shell and a cap. The shell has a first cavity for holding bromine, with an opening at one end. The cap is placed over the opening to separate the first cavity from the outside. When in use, simply removing the cap releases the scent. Current scent pens can only release one scent at a time; multiple pens are needed for different scents. For example, four scent pens might be included, each with a different scent: rose, lemon, eucalyptus, and clove. During olfactory training, patients are asked to remove the cap, place the pen tip 2-3 cm in front of their nostrils, and inhale each scent for 10-20 seconds, twice a day, morning and evening.

[0004] However, since each scent pen contains only one scent, multiple scent pens are needed for olfactory training with multiple scents, making the existing scent pens impractical for training. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is that, due to the relatively simple scent inside a single scent pen in the prior art, some scent pens are not practical during training.

[0006] Therefore, the present invention provides an olfactory training device, comprising:

[0007] The housing has a first receiving cavity and a first opening communicating with the first receiving cavity;

[0008] At least two snorkels, adjacent snorkels contain different types of odorants, each snorkel has a release end, and each snorkel can be movably installed inside a first receiving cavity. Under the action of an external force, any one of the snorkels moves toward the first opening until the release end moves to the first opening and releases the odorant to the outside of the housing.

[0009] Optionally, the above-mentioned olfactory training device,

[0010] The housing is a cylindrical structure, and the housing also includes a second opening, which communicates with the first receiving cavity, and the second opening and the first opening are respectively disposed at both ends of the housing along the axial direction of the housing;

[0011] The sniffing stick has a first body, which is located inside the first receiving cavity;

[0012] It also includes at least two first handles, each of which corresponds to a sniffing rod. Each first handle has a second body, a first limiting part, and a handle. The second body is located inside a first receiving cavity, and a second receiving cavity is provided inside the second body. The first limiting part is located in the second receiving cavity and is used to abut against the end face of the second body away from the release end. The handle is located on the side of the second body away from the release end and on the side of the second opening away from the first receiving cavity. Under the action of external force, the handle drives the second body to move along the axial direction of the housing.

[0013] Optionally, the above-mentioned olfactory training device,

[0014] The housing further includes a third opening, which is located between the first opening and the second opening, and the opening direction of the third opening is the radial direction of the housing;

[0015] The first handle is further provided with a second limiting part, the second limiting part includes a first end and a second end disposed away from the first end, the first end is connected to the second body, the second end is spaced apart from the second body, the second end has a first state located inside the third opening to limit the movement of the second body along the axial direction of the housing, the second end also has a second state abutting against the inner wall surface of the housing, and the second end is switched between the first state and the second state.

[0016] Wherein, an external force acts on the handle part along the axis of the housing, the handle part drives the second body to move along the axis of the housing, the second body drives the first end to move along the axis of the housing, the first end drives the second end to move along the axis of the housing until the second end switches from the second state to the first state.

[0017] Optionally, the above-mentioned olfactory training device further includes:

[0018] The second handle has a third end and a fourth end located away from the third end. The third end is rotatably mounted on the housing. The fourth end is spaced apart from the third opening along the radial direction of the housing. A pressing protrusion is provided on the side of the fourth end near the third opening.

[0019] An external force acts on the fourth end along the radial direction of the housing, and the fourth end moves towards the side near the third opening until the pressing protrusion abuts against the second end, and the second end moves toward the direction near the first receiving cavity.

[0020] Optionally, the above-mentioned olfactory training device,

[0021] The sniffing stick is provided with a third limiting part, which is located on the side of the first body near the first opening, and the third limiting part is arranged on the outside of the first body along the radial direction of the housing.

[0022] The housing is provided with a fourth limiting part, which extends radially inside the housing and is spaced apart from the third limiting part along the axial direction.

[0023] It also includes a biasing component, which is sleeved on the first body. When the biasing component is in its natural state, both ends of the biasing component abut against the third limiting part and the fourth limiting part, respectively.

[0024] During the process of the second end switching from the second state to the first state, the biasing member changes from the natural state to the pressed state; the pressing protrusion drives the second end to move into the first receiving cavity, and the biasing member returns from the pressed state to the natural state.

[0029] Optionally, the above-mentioned olfactory training device,

[0030] The release end is an elastic structure, and the release end includes a first deformation part and a second deformation part. When the release end is in its natural state, the first deformation part abuts against the second deformation part to separate the olfactory substance inside the olfactory stick from the outside. When an external force is applied to the first handle, the release end moves toward the first opening until the shell acts on the release end. The first deformation part and the second deformation part are spaced apart to form a deformation slit.

[0031] Optionally, the above-mentioned olfactory training device,

[0032] The release end is detachably connected to the first body.

[0033] Optionally, the above-mentioned olfactory training device,

[0034] It also includes a mounting bracket, which is located inside the housing and has at least two through holes along the circumferential direction of the housing;

[0035] Each smelling stick corresponds to a through hole and is inserted through the through hole.

[0036] The technical solution provided by this invention has the following advantages:

[0037] 1. The olfactory training device provided by the present invention includes a housing and at least two olfactory sticks. The housing has a first receiving cavity and a first opening communicating with the first receiving cavity; adjacent olfactory sticks contain different types of olfactory substances, each olfactory stick has a release end, and each olfactory stick is movably installed inside the first receiving cavity. Under the action of an external force, any one of the olfactory sticks moves towards the first opening until the release end moves to the first opening and releases the olfactory substance to the outside of the housing.

[0038] This olfactory training device, by setting the number of olfactory sticks to at least two, allows each olfactory stick to be movably installed in the first receiving cavity of the housing. When any olfactory stick is moved by external force, if the release end of the olfactory stick moves to the first opening, it can be used for olfactory training by the patient. After the patient completes the olfactory training with this olfactory stick, the olfactory stick is retracted into the first receiving cavity by external force, and then the other olfactory sticks can be moved. Compared with the existing solution where a single odor pen can only be used for training with one odor, the olfactory training device with this structure can be used for training with at least two odors, thus improving the practicality of the olfactory training device.

[0039] 2. The olfactory training device provided by the present invention has a release end that is an elastic structure. The release end includes a first deformation part and a second deformation part. When the release end is in a natural state, the first deformation part abuts against the second deformation part to separate the olfactory substance inside the olfactory stick from the outside. When an external force acts on the first handle, the release end moves toward the first opening until the shell acts on the release end. The first deformation part and the second deformation part are spaced apart to form a deformation slit.

[0040] This olfactory training device features a flexible release end. When olfactory training is not required, the release end is in its natural state, with the first deformation part abutting against the second deformation part, closing the release end and separating the olfactory substance inside the olfactory stick from the outside. When olfactory training is required, applying external force to one of the first handles causes the first handle to move a first body. The release end of the first body moves towards the first opening until the shell acts on the release end. At this point, the first and second deformation parts move away from each other, forming a deformation slit. This allows the olfactory substance inside the olfactory stick to flow through the deformation slit to the outside for the patient to perform olfactory training. At this time, the remaining olfactory sticks are located inside the first receiving cavity, with their release ends closed, eliminating concerns about interference between multiple olfactory sticks and further enhancing the practicality of the olfactory training device.

[0059] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0060] Example 1

[0061] This embodiment provides an olfactory training device, such as Figures 1 to 7 As shown, it includes: a housing 1 and at least two olfactory sticks 2. The housing 1 has a first receiving cavity and a first opening 11 communicating with the first receiving cavity; the types of olfactory substances contained inside adjacent olfactory sticks 2 are different, each olfactory stick 2 has a release end 21, and each olfactory stick 2 can be movably installed inside the first receiving cavity. Under the action of external force, any olfactory stick 2 moves toward the first opening 11 until the release end 21 moves to the first opening 11 and releases the olfactory substance to the outside of the housing 1.

[0062] This olfactory training device, by setting the number of olfactory sticks 2 to at least two, allows each olfactory stick 2 to be movably installed in the first receiving cavity of the housing 1. When an external force is applied to move any olfactory stick 2, if the release end 21 of the olfactory stick 2 moves to the first opening 11, it can be used for olfactory training by the patient. After the patient completes the olfactory training of this olfactory stick 2, the external force is applied to retract the olfactory stick 2 into the first receiving cavity, and then the other olfactory sticks 2 can be moved. Compared with the existing solution where only one odor pen can be used for training, the olfactory training device with this structure can be used for training of at least two odors, thus improving the practicality of the olfactory training device.

[0063] It should be noted that this embodiment provides an olfactory training device, and does not limit the type and concentration of endolorhines in the olfactory stick 2.

[0064] It should be noted that this embodiment provides an olfactory training device, and the structure of the housing 1 is not limited. As one implementation method, such as... Figures 1 to 7 As shown, shell 1 is a cylindrical structure.

[0065] Furthermore, in this embodiment, the housing 1 further includes a second opening 12, which communicates with the first receiving cavity, and the second opening 12 and the first opening 11 are respectively disposed at both ends of the housing 1 along the axial direction of the housing 1; the sniffing rod 2 is provided with a first body 22, which is located inside the first receiving cavity; it also includes at least two first handles 3, which are disposed one-to-one with the sniffing rod 2. The first handle 3 has a second body 31, a first limiting part 32 and a handle part 33. The second body 31 is located inside the first receiving cavity, and the second body 31 is provided with a second receiving cavity. The first limiting part 32 is located in the second receiving cavity and is used to abut against the end face of the second body 31 away from the release end 21. The handle part 33 is located on the side of the second body 31 away from the release end 21 and on the side of the second opening 12 away from the first receiving cavity. Under the action of external force, the handle part 33 drives the second body 31 to move along the axial direction of the housing 1.

[0066] It should be noted that in the above embodiments, the number of smelting rods 2 is not limited, and can be two, three, four or more. As one implementation, the number of smelting rods 2 is selected as four. In this case, the four smelting rods 2 are evenly distributed along the circumference of the housing 1 inside the first receiving cavity.

[0067] like Figures 1 to 7 As shown, the olfactory training device provided in this embodiment includes a third opening 13 in the housing 1. The third opening 13 is located between the first opening 11 and the second opening 12, and the opening direction of the third opening 13 is the radial direction of the housing 1. The first handle 3 is also provided with a second limiting part 34, which includes a first end 341 and a second end 342 disposed away from the first end 341. The first end 341 is connected to the second body 31, and the second end 342 is spaced apart from the second body 31. The second end 342 has a function located inside the third opening 13 to limit the second body 31. In the first state, the second end 342 moves along the axial direction of the housing 1, and in the second state, the second end 342 also has a second state that abuts against the inner wall surface of the housing 1. The second end 342 is switched between the first state and the second state. In this case, an external force acts on the handle 33 along the axial direction of the housing 1, the handle 33 drives the second body 31 to move along the axial direction of the housing 1, the second body 31 drives the first end 341 to move along the axial direction of the housing 1, the first end 341 drives the second end 342 to move along the axial direction of the housing 1 until the second end 342 switches from the second state to the first state.

[0068] like Figures 1 to 7 As shown, the olfactory training device provided in this embodiment also includes a second handle 4, which has a third end 411 and a fourth end 412 disposed away from the third end 411.

[0069] It can be noted that the number of the second handle 4 in the olfactory training device provided in this embodiment is not limited, and can be one, four or more.

[0070] In one embodiment, the number of second handle members 4 is one. In this case, the third end 411 is rotatably mounted on the housing 1, and the fourth end 412 is spaced apart from the third opening 13 along the radial direction of the housing 1. A pressing protrusion 413 is provided on the side of the fourth end 412 near the third opening 13. When an external force is applied to the fourth end 412 along the radial direction of the housing 1, the side of the fourth end 412 near the third opening 13 moves until the pressing protrusion 413 abuts against the second end 342, and the second end 342 moves toward the direction of the first receiving cavity. In use, by rotatably mounting the third end 411 of the second handle member 4 on the housing 1, it is only necessary to rotate the third end 411 until the fourth end 412 is aligned with the desired retractable sniffing rod 2.

[0071] Of course, in other alternative embodiments, the number of second handle parts 4 is selected to be four. In this case, the four second handle parts 4 share a third end 411 and each has a fourth end 412. The fourth end 412 is set in the same way as described above. In this case, the four fourth ends 412 are respectively set along the radial direction of the housing 1 to correspond to the four sniffing rods 2. When in use, there is no need to rotate the third end 411. Just press the fourth end 412 that corresponds to the desired sniffing rod 2.

[0072] Furthermore, different marking structures, such as color markings, can be provided on the second handle 4 to facilitate the flexible replacement of the required olfactory substance by the physician during use.

[0073] In this olfactory training device, the fourth end 412 is spaced apart from the third opening 13 along the radial direction of the housing 1 to form a snap-fit ​​structure. After olfactory training is completed, if it is necessary to store the olfactory training device, the doctor can easily snap it into his pocket through the fourth end 412 to store the olfactory training device, thereby further improving the practicality of the olfactory training device.

[0074] like Figures 1 to 7As shown, the olfactory training device provided in this embodiment includes a olfactory stick 2 with a third limiting part 23 located on the side of the first body 22 near the first opening 11, and the third limiting part 23 is arranged on the outside of the first body 22 along the radial direction of the housing 1; the housing 1 is provided with a fourth limiting part extending radially inside the housing 1, and the fourth limiting part and the third limiting part 23 are spaced apart along the axial direction; it also includes a biasing member 5, which is sleeved on the first body 22. When the biasing member 5 is in its natural state, its two ends abut against the third limiting part 23 and the fourth limiting part, respectively; wherein, during the process of the second end 342 switching from the second state to the first state, the biasing member 5 changes from the natural state to the pressed state; the pressing protrusion 413 drives the second end 342 to move into the first receiving cavity, and the biasing member 5 returns from the pressed state to the natural state.

[0075] It can be noted that the olfactory training device provided in this embodiment does not limit the structure of the third limiting part 23. It can be a protrusion structure installed on the surface of the first body 22, or a ring structure sleeved on the outside of the first body 22. As one embodiment, the third limiting part 23 is a ring structure, and the radial dimension of the inner ring of the ring structure is equal to the radial dimension of the outer surface of the first body 22 near the first opening 11, so as to facilitate the installation of the ring structure on the first body 22. The radial dimension of the outer ring of the ring structure is smaller than the radial dimension of the inner surface of the housing 1, so as to facilitate the movement of the ring structure inside the first receiving cavity.

[0076] Furthermore, in this embodiment, the fourth limiting part has the same structure as the third limiting part 23. The outer ring structure of the fourth limiting part is directly mounted on the inner wall surface of the housing 1. At this time, the two ends of the biasing member 5 abut against the end faces of the third limiting part 23 and the fourth limiting part, which are close to each other and arranged opposite to each other.

[0077] like Figures 1 to 7 As shown, the olfactory training device provided in this embodiment also includes a olfactory block. The olfactory block is positioned at the release end 21 of the olfactory stick 2.

[0078] It should be noted that the olfactory training device provided in this embodiment does not limit the selection of the olfactory block. As one implementation, the olfactory block is made of sponge. During installation, the sponge extends into the interior of the olfactory rod 2 to contact the olfactory pigment, facilitating olfactory training for the patient.

[0079] The olfactory training device provided in this embodiment should have a leak-proof measure at the release end 21, that is, when the olfactory stick 2 is not in use, the olfactory substance inside the olfactory stick 2 should be prevented from evaporating to the outside.

[0080] As one implementation method, such as Figures 1 to 7As shown, the release end 21 is an elastic structure. The release end 21 includes a first deformation part and a second deformation part. When the release end 21 is in its natural state, the first deformation part abuts against the second deformation part to separate the olfactory substance inside the olfactory stick 2 from the outside. When an external force acts on the first handle 3, the release end 21 moves toward the first opening 11 until the housing 1 acts on the release end 21. The first deformation part and the second deformation part are spaced apart to form a deformation slit.

[0081] Specifically, in this embodiment, the release end 21 is made of rubber, and the first deformable part and the second deformable part are positioned to abut against each other in their natural state, so as to separate the olfactory substance inside the olfactory stick 2 from the outside. Specifically, one or both of the first deformable part and the second deformable part are connected to form multiple arc structures with different radii, and the radial dimension of the arc set near the first opening 11 is smaller than the size of the first opening 11, while the radial dimension of the arc set away from the first opening 11 is larger than the size of the first opening 11. When the olfactory training device is in use, if the smaller arc passes through the first opening 11 and gradually extends to the outside, the housing 1 contacts and squeezes the arc with the larger radial dimension, which can cause the portions of the first deformable part and the second deformable part extending out of the first opening 11 to move away from each other, forming a deformable slit.

[0082] Of course, in other alternative embodiments, a first sealing element is provided at the release end 21. The first sealing element is threadedly engaged with the release end 21. When in use, the first sealing element can be loosened and removed for use in olfactory training. At the same time, the first sealing element can be removed at any time to take out the olfactory stick 2 for the doctor to check the remaining amount of olfactory substance in the olfactory stick 2.

[0083] It can be noted that in the olfactory training device provided in this embodiment, the release end 21 is detachably connected to the first body 22, such as by a threaded connection. After the olfactory substance inside the olfactory stick 2 has been fully utilized, the release end 21 can be removed, the first body 22 of the old olfactory stick 2 can be taken out, and the first body 22 of the new olfactory stick 2 can be replaced.

[0084] like Figures 1 to 7 As shown, the olfactory training device provided in this embodiment also includes a mounting bracket for separating the multiple olfactory sticks 2. The mounting bracket is located inside the housing 1, and the mounting bracket has at least two through holes along the circumferential direction of the housing 1; the olfactory sticks 2 correspond one-to-one with the through holes and pass through them.

[0085] like Figures 1 to 7As shown, the olfactory training device provided in this embodiment also includes a second sealing member, which is located along the axial direction of the housing 1 on the side of the first handle 3 away from the first receiving cavity. The second sealing member is detachably installed to the housing 1, such as through a threaded connection. In use, the second sealing member is loosened from the housing 1 and removed to allow for olfactory training. After completing the olfactory training, the second sealing member is tightened back onto the housing 1 to prevent the olfactory substance inside the olfactory stick 2 from being contaminated by dust or other dirt, thus affecting the use of the next olfactory training session.

[0086] like Figures 1 to 7 As shown, the olfactory training device provided in this embodiment also includes a third body with multiple side holes 14 in the housing 1. The third body is detachably connected to the housing 1 to prevent dust and dirt from contaminating the olfactory substance. The multiple side holes 14 are evenly distributed along the axial direction of the housing 1, which facilitates the olfactory substance to be evenly released to the outside after the olfactory stick 2 enters the third body.

[0087] like Figures 1 to 7 As shown, the olfactory training device provided in this embodiment has a groove on the side of the housing 1 near the multiple side holes 14. At this time, a friction element 6 is added and installed in the groove so that the doctor can hold it.

[0088] In the above-described olfactory training device, when olfactory training is required, external force along the axial direction of the housing 1 drives the first handle 3 to move, the third limiting part 23 and the fourth limiting part move closer together, and the biasing part 5 changes from a natural state to a compressed state to store energy. At this time, the release end 21 is located on the side of the first opening 11 away from the first receiving cavity, until the housing 1 squeezes one or both of the first and second deformation parts, the first and second deformation parts move away from each other to form a deformation slit for the patient to perform olfactory training; when it is necessary to replace the olfactory stick 2 or when olfactory training has been completed, external force acts on the second handle 4 along the radial direction of the housing, and the pressing protrusion 413 abuts against the third... The limiting part 23 moves closer to the first receiving cavity until it enters the first receiving cavity. Then, the limiting part 23 loses its limiting effect on the housing 1, and the biasing member 5 returns from the pressurized state to the natural state, completing the energy release. At this time, due to the fixed setting of the fourth limiting part, the third limiting part 23 moves away from the first opening 11 under the action of the biasing member 5. The first body 22 moves closer to the second opening 12 under the drive of the third limiting part 23. The release end 21 enters the interior of the first receiving cavity. The first deformation part and the second deformation part move closer to each other to close the deformation slit, thereby separating the odorant inside the olfactory stick 2 from the outside world and preventing the odorant from evaporating or becoming contaminated.

[0089] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
