Description

Technical Field

[0001] This application relates to the field of phototherapy equipment technology, and in particular to a cap limiting component for a phototherapy equipment and a phototherapy equipment. Background Technology

[0002] Currently, in the field of transcranial phototherapy, treatment caps work by irradiating the head with light to produce therapeutic effects. The patient's head may not be securely held within the treatment cap, especially when using phototherapy devices to treat Alzheimer's disease (AD) patients, where the cap needs to be designed to allow for slight forward, backward, left, and right movements of the head. To prevent the patient's head from slipping out of the treatment area due to excessive head movements, a chin strap is used to support the chin while wearing the cap. Currently, the chin strap is worn with Velcro; one side is smooth, the other is textured, and both ends have Velcro. This allows the chin strap to support the patient's chin each time it is worn. However, after phototherapy, removing the chin strap requires tearing off one end of the Velcro, which is inconvenient. Furthermore, the Velcro's position is difficult to match the previous wear, requiring constant adjustments to ensure proper placement. This introduces uncertainty into the wearing process, hindering accurate wearing and affecting treatment effectiveness. Utility Model Content

When a specific device is described as being connected to other devices, the specific device may be directly connected to the other devices without an intermediary device, or it may not be directly connected to the other devices but may have an intermediary device.

[0023] All terms used in this application (including technical or scientific terms) have the same meaning as understood by one of ordinary skill in the art to which this application pertains, unless otherwise specifically defined. It should also be understood that terms defined in general dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant art, and not as having an idealized or highly formalized meaning, unless expressly defined herein.

[0024] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0025] This application provides a cap-limiting component for a phototherapy device. For example... Figure 1 and Figure 2As shown, the phototherapy device includes a headgear 1 and a suspension assembly 2. The suspension assembly 2 is used to suspend the headgear 1 above the head, forming a spacer cavity between the headgear 1 and the head. A headgear limiting assembly is used to limit the movement of the head within the spacer cavity. The headgear limiting assembly includes a connecting assembly 3 and a chin assembly. The connecting assembly 3 is detachably connected to one side of the headgear 1. The chin assembly includes a chin strap 4 and a first positioning adjustment member 5. The chin strap 4 is used to fit against the chin of the head. One end of the chin strap 4 is connected to the other side of the headgear 1, and the other end of the chin strap 4 is connected to the connecting assembly 3 through the first positioning adjustment member 5. The first positioning adjustment member 5 includes a first engaging portion (not shown in the figure), several second engaging portions 51 adapted to the first engaging portion, and a bendable first adjustment band 52. The several second engaging portions 51 are spaced apart along the length direction of the first adjustment band 52. The first engaging portion engages with one of the several second engaging portions 51 to adjust the distance between the other end of the chin strap 4 and the connecting assembly 3.

[0026] The aforementioned suspension component 2 can be connected to the upper part of the headgear 1 to suspend the headgear 1, so that the headgear 1 is suspended above the head, forming a spacer cavity between the headgear 1 and the head. When the patient wears the headgear 1, he / she can move within the spacer cavity to improve the comfort of wearing the headgear 1. Without the patient's head leaving the spacer cavity, the phototherapy device can ensure effective treatment of the head, that is, it can ensure both comfort and treatment effect.

[0027] The aforementioned connecting component 3 and the head cap 1 can be detachably connected by means such as snap-fit ​​connection, threaded connection, magnetic connection, etc. When the phototherapy begins or ends, the cap limiting component can be connected to or detached from the head cap 1 by operating the connecting component 3. That is, each time the patient uses the phototherapy device, he / she only needs to operate the connecting component 3 and does not need to operate the first positioning adjustment component 5 of the mandibular component, which simplifies the operation for the patient.

[0028] When a patient uses the phototherapy device for the first time, the first positioning adjustment component 5 can be selected from several second locking parts 51 to engage with the first locking part. After engagement, the distance between the other end of the chin strap 4 and the connecting component 3 can remain unchanged. After the phototherapy ends and before the next phototherapy session, the first positioning adjustment component 5 does not need to be adjusted repeatedly. This effectively ensures that the distance between the other end of the chin strap 4 and the connecting component 3 remains consistent without adjusting the first positioning adjustment component 5, thus facilitating the patient's operation of the connecting component 3.

[0029] Of course, if the patient needs to adjust the distance between the other end of the chin strap 4 and the connecting component 3, other second locking parts 51 can be selected to engage with the first locking part to adjust the distance between the other end of the chin strap 4 and the connecting component 3, so that the cap limiting component can act more appropriately on the head and avoid the problem of the chin component being too loose or too tight.

[0030] The number and position of the aforementioned second locking portions 51 can be related to head size so that, after adjusting the first positioning adjustment member 5, the cap limiting assembly can cover the head size of most patients. For example, as Figure 1 As shown, Figure 1 The number of the second engaging parts 51 shown is three, for example only.

[0031] The aforementioned second locking part 51 can be detachably connected to the first adjustment band 52. After the first locking part is engaged with one of the several second locking parts 51, the other second locking parts 51 can be detached from the first adjustment band 52, so that only the second locking part 51 that is adapted to the size of the patient's head is retained, thereby further ensuring that the position of the patient wearing it is consistent each time.

[0032] The first adjustment band 52 can be made of a shearable material. After the first locking part is engaged with one of the several second locking parts 51, the remaining second locking parts 51 can be removed by cutting the first adjustment band 52. In this way, when using it again, the first locking part is engaged with the second locking part 51 closest to the cutting position, which makes it convenient for the patient to quickly adjust the chin component to fit the size of the patient's head, thereby further ensuring that the position of the patient wearing it is consistent each time.

[0033] This application utilizes a cap-body limiting component to restrict head movement within the spacer cavity. Specifically, the head can move freely within the spacer cavity between the cap-body limiting component and the cap 1 suspended by the suspension component 2, without exiting the spacer cavity. This ensures sufficient head movement space while preventing excessive head movement and head displacement from the spacer cavity. Furthermore, the first positioning adjustment component 5 of the cap-body limiting component can be engaged with one of the first locking portion and several second locking portions 51, ensuring consistency in the patient's use of the phototherapy device each time. Specifically, the first positioning adjustment component 5 ensures that the distance between the other end of the chin strap 4 and the connecting component 3 remains consistent each time the device is worn, eliminating the need for the patient to constantly adjust the length of the chin strap and ensuring the effectiveness of the phototherapy. Additionally, the detachable connection between the connecting component 3 and the cap 1 facilitates installation and removal for the patient, increasing operational convenience.

[0034] In some embodiments, such as Figure 1 and Figure 2As shown, the first locking part and several second locking parts 51 are arranged sequentially along the length direction of the first adjusting band 52, and the first adjusting band 52 is integrated with the chin strap 4. In this way, the first locking part and the second locking parts 51 can be engaged by bending the first adjusting band 52. The above structure facilitates the patient's operation of the first positioning adjustment member 5, thereby adjusting the distance between the other end of the chin strap 4 and the connecting component 3.

[0035] The length direction of the first adjustment band 52 can be consistent with the length direction of the chin strap 4, and one end of the first adjustment band 52 can pass through the connecting component 3 and be bent so that the first engaging portion can engage with the second engaging portion 51. Specifically, the first adjustment band 52 can have a bent portion that contacts the connecting component 3, and the first engaging portion and several second engaging portions 51 can be located on opposite sides of the bent portion. The first engaging portion can be positioned closer to the chin strap 4 relative to the several second engaging portions 51, or the first engaging portion can be positioned farther away from the chin strap 4 relative to the several second engaging portions 51. This application does not make specific limitations in this regard, as long as the first engaging portion and the second engaging portion 51 can be stably engaged.

[0036] The integration of the first adjustment band 52 and the mandibular band 4 can be understood as either the first adjustment band 52 and the mandibular band 4 being connected as a single unit, or as the first adjustment band 52 and the mandibular band 4 being integrally formed. This integration ensures the structural integrity of the mandibular component. Preferably, the first adjustment band 52 and the mandibular band 4 are integrally formed, ensuring material consistency, simplifying the manufacturing process, and significantly reducing production costs. This application does not specifically limit the integration method of the first adjustment band 52 and the mandibular band 4, as long as they maintain a stable relative positional relationship.

[0037] In some embodiments, such as Figure 1 and Figure 2 As shown, the cap body limiting assembly also includes a safety buckle 6 that is detachably connected to the cap 1. One end of the chin strap 4 is connected to the other side of the cap 1 through the safety buckle 6. The safety buckle 6 is used to detach from the cap 1 when the applied force exceeds a preset threshold.

[0038] In this way, the safety buckle 6 can avoid the risk of the chin strap 4 strangling the patient's neck due to accidental situations, thus improving the safety of using the phototherapy device.

[0039] The aforementioned preset threshold range can be greater than 80N. For example, if the force on the safety buckle 6 exceeds 80N, the safety buckle 6 will detach from the headgear 1.

[0040] The aforementioned safety buckle 6 and the head cap 1 can be detachably connected by means such as snap-fit ​​connection or magnetic connection. For example, the aforementioned safety buckle 6 may include a claw, and the head cap 1 is provided with a locking shaft. The claw forms a locking groove with an opening on one side. The claw can deform to allow the locking shaft to be inserted into the locking groove through the opening. When the applied force exceeds a preset threshold, the claw deforms to increase the size of the opening, thereby releasing the locking shaft and realizing that the locking shaft is disengaged from the locking groove.

[0041] In some embodiments, such as Figure 2 As shown, the headgear 1 is provided with a plug-in component 11, and the connecting component 3 is detachably connected to the plug-in component 11 for detachable connection with the headgear 1.

[0042] Thus, the headgear 1 can be put on or taken off simply by detaching the connecting component 3 and the plug-in component 11 each time the phototherapy device is used, without the need for any other operations, thus improving the convenience of operation.

[0043] The aforementioned plug-in component 11 may have a socket, and the connecting component 3 may be inserted into the socket of the plug-in component 11 to connect with the plug-in component 11.

[0044] In some embodiments, such as Figure 1 As shown, the connecting component 3 is provided with a snap button 31, which is used to disengage the connecting component 3 from the plug-in member 11 when triggered. The connecting component 3 has a simple structure and is easy for the patient to operate.

[0045] The aforementioned snap button 31 can engage with the plug-in component 11 when no force is applied, and deform and disengage from the plug-in component 11 after force is applied, thereby achieving locking and unlocking of the connecting component 3 and the plug-in component 11.

[0046] In some embodiments, such as Figure 1 and Figure 2 As shown, the mandibular band 4 is provided with several through grooves 41, which are spaced apart along the length of the mandibular band 4.

[0047] In this way, by setting the through groove 41, the deformation of the chin strap 4 can be increased, so that the chin strap 4 can better fit the lower jaw towards the head, and the breathability of the chin strap 4 can also be increased, thereby improving the comfort of wearing the chin strap 4.

[0048] The aforementioned through groove 41 can be constructed as a long strip, and its length direction can be perpendicular to the length direction of the mandibular band 4.

[0049] The aforementioned groove 41 can be set at the middle part of the lower jaw of the head after the patient wears the chin strap 4, so as to better fit the lower jaw.

[0050] In some embodiments, the chin strap 4 is made of a flexible material so that it conforms to the lower jaw of the head through deformation.

[0051] The aforementioned mandibular band 4 can be made of textile fiber materials, nylon materials, or other materials.

[0052] In some embodiments, such as Figure 1 and Figure 2 As shown, the mandibular component also includes a second positioning adjustment member 7. The safety buckle 6 is connected to one end of the mandibular band 4 through the second positioning adjustment member 7. The second positioning adjustment member 7 is used to adjust the distance between one end of the mandibular band 4 and the safety buckle 6.

[0053] In this way, the position of the chin strap 4 relative to the lower jaw of the head can be adjusted by coordinating the first positioning adjustment member 5 and the second positioning adjustment member 7, increasing the flexibility of adjusting the position of the chin strap 4. In particular, the middle part of the chin strap 4 can be better aligned with the lower jaw of the head, that is, the chin strap 4 can be centrally positioned to better act on the head and more stably limit the head's position.

[0054] In some embodiments, such as Figure 1 and Figure 2 As shown, the second positioning adjustment member 7 includes a third engaging part (not shown in the figure), a plurality of fourth engaging parts 71 adapted to the third engaging part, and a second adjustment band 72 that can be bent. The plurality of fourth engaging parts 71 are spaced apart along the length direction of the second adjustment band 72. The third engaging part engages with one of the plurality of fourth engaging parts 71 to adjust the distance between one end of the chin strap 4 and the safety buckle 6.

[0055] The aforementioned second positioning adjustment element 7 can be integrated with the mandibular band 4. For example, the second adjustment band 72 can be connected to the mandibular band 4 as a single unit, or the second adjustment band 72 and the mandibular band 4 can be integrally formed. This integration ensures the structural integrity of the mandibular assembly. Preferably, the second adjustment band 72 and the mandibular band 4 are integrally formed, ensuring material consistency, simplifying the manufacturing process, and significantly reducing production costs. This application does not specifically limit the integration method of the second adjustment band 72 and the mandibular band 4, as long as a stable relative positional relationship is achieved between them.

[0056] The aforementioned second positioning adjustment component 7 can be selected from several fourth locking parts 71 to engage with the third locking part when the patient uses the phototherapy device for the first time. After engagement, the distance between one end of the chin strap 4 and the safety buckle 6 can remain unchanged. After the phototherapy ends and before the next phototherapy session, there is no need to repeatedly adjust the second positioning adjustment component 7. This effectively ensures that the distance between one end of the chin strap 4 and the safety buckle 6 remains consistent without adjusting the second positioning adjustment component 7, thus facilitating the patient's operation of the connecting component 3.

[0057] Of course, if the patient needs to adjust the distance between one end of the chin strap 4 and the safety buckle 6, other fourth locking parts 71 can be selected to engage with the third locking parts to adjust the distance between one end of the chin strap 4 and the safety buckle 6, so that the cap limiting component can act more appropriately on the head and avoid the problem of the chin component being too loose or too tight.

[0058] The number and position of the aforementioned fourth locking parts 71 can be related to the head size so that, after adjusting the second positioning adjustment member 7, the cap limiting assembly can cover most patients' head sizes. For example, as Figure 1 As shown, Figure 1 The number of fourth engaging parts 71 shown is three, for example only.

[0059] The aforementioned fourth locking part 71 can be detachably connected to the second adjustment band 72. After the third locking part is engaged with one of the several fourth locking parts 71, the other fourth locking parts 71 can be detached from the second adjustment band 72, so that only the fourth locking part 71 that is adapted to the size of the patient's head is retained, thereby further ensuring that the position of the patient wearing it is consistent each time.

[0060] The aforementioned third locking portion and several fourth locking portions 71 are sequentially arranged along the length of the second adjusting band 72, and the second adjusting band 72 is integrated with the chin strap 4. Thus, the third locking portion and the fourth locking portions 71 can be engaged by bending the second adjusting band 72. This structure facilitates the patient's operation of the second positioning adjustment element 7, thereby adjusting the distance between one end of the chin strap 4 and the safety buckle 6.

[0061] The second adjustment band 72 can be made of a shearable material. After the third locking part is engaged with one of the several fourth locking parts 71, the remaining fourth locking parts 71 can be removed by cutting the second adjustment band 72. Thus, when using it again, the third locking part is engaged with the fourth locking part 71 closest to the cutting position, allowing the patient to quickly adjust the chin assembly to fit the patient's head size, thereby further ensuring that the position is consistent for each use.

[0062] This application also provides a phototherapy device, including a cap limiting component for phototherapy devices according to any of the above embodiments, and a head cap 1 and a suspension component 2. The suspension component 2 is used to suspend the head cap 1 above the head, and to form a spacer cavity between the head cap 1 and the head. The cap limiting component is used to limit the movement of the head within the spacer cavity.

[0063] The phototherapy device provided in this application is used to treat Alzheimer's disease and related conditions. The phrase "used to treat Alzheimer's disease and related conditions" in this application is intended to indicate that it alleviates, inhibits, terminates, or even reverses the progression of Alzheimer's disease and related conditions. The term "related conditions" refers to pathological or physiological phenomena associated with Alzheimer's disease that exist before the subject exhibits obvious clinical symptoms of AD and have a certain probability of developing into AD. The term "progression" of Alzheimer's disease and related conditions includes both the occurrence of clinical symptoms of AD and the subsequent progression, as well as the occurrence of pathological or physiological phenomena associated with AD that have a certain probability of developing into AD before the subject exhibits obvious clinical symptoms of AD. In other words, the phrase "used to treat Alzheimer's disease and related conditions" in this application includes treating Alzheimer's disease at various stages (from mild cognitive impairment to severe dementia) and also includes treating other conditions associated with Alzheimer's disease.

[0064] Patients with Alzheimer's disease and related conditions are prone to emotional agitation, anxiety, and restlessness. The phototherapy device provided in this application suspends a headgear 1 above the patient's head through a suspension component 2, and creates a space between the headgear 1 and the patient's head to form a loose and open headgear 1 design. This design does not restrict the patient's head and is especially friendly to patients who are emotionally agitated, anxious, resistant, or even afraid of enclosed or crowded spaces. It can significantly improve the treatment compliance of patients with Alzheimer's disease and related conditions.

[0065] The aforementioned phototherapy device, through its cap-limiting component, restricts the movement of the patient's head within the septum. Specifically, the patient's head can move within the septum between the cap-limiting component and the headgear 1 suspended by the suspension component 2, without exiting the septum. This ensures sufficient head movement space for the patient, improving treatment compliance, while preventing excessive head movement and displacement from the septum. Furthermore, the first positioning adjustment component 5 of the cap-limiting component is connected via a first locking part and one of several second locking parts 51, ensuring consistency in the patient's use of the phototherapy device each time. Specifically, the first positioning adjustment component 5 ensures that the distance between the other end of the chin strap 4 and the connecting component 3 remains consistent each time the device is worn, eliminating the need for the patient to constantly adjust the length of the chin strap and ensuring the effectiveness of the phototherapy. Additionally, the detachable connection between the connecting component 3 and the headgear 1 facilitates installation and removal for the patient, increasing operational convenience.
