Description

Technical Field

[0001] This application relates to the technical field of small intelligent medical devices; more specifically, to non-rinsing nasal medication delivery protocols; and more specifically, to an intelligent nasal sprayer. Background Technology

[0002] Rhinitis refers to inflammation of the nasal mucosa and submucosal tissues. Symptoms of rhinitis include congestion or edema, and patients often experience nasal congestion, runny nose with clear discharge, nasal itching, throat discomfort, and coughing. Currently, the simplest and most effective comprehensive prevention and treatment for nasal diseases is nasal irrigation with saline solution. This involves regularly rinsing the nasal cavity with isotonic or hypertonic saline solution to help remove harmful substances adhering to the nasal cilia and reduce their irritation. Nasal sprays containing saline solution can be categorized into two types. One relies on manual pressure applied to the nozzle to spray saline solution from the rinsing bottle, creating a mist. However, the spray volume and atomization effect vary depending on the pressure applied. Another type utilizes a micro-motor to generate compressed airflow, continuously atomizing the saline solution through gas-liquid mixing. Examples include Chinese invention application CN113041140 A (published June 29, 2021, "An Adjustable Temperature Nasal Rinsement Device") and Chinese invention application CN110151534 A (published August 23, 2019, "An Adjustable Temperature Nasal Rinsement Device"), both employing this approach.

[0003] Besides nasal irrigation with saline solution, nasal drops are also used to relieve rhinitis symptoms. For example, nasal oil can relieve dryness in dry rhinitis, ephedrine / furazolidone mixture can relieve nasal congestion, and sulfadiazine / ephedrine nasal drops can treat acute and chronic rhinitis and sinusitis. Currently, these non-rinsing nasal medications are generally administered by tilting the patient's head back and squeezing the bottle to dispense the medication into the nasal cavity. However, existing non-rinsing nasal medication regimens are all designed for liquid medications and cannot be applied to gel-based medications or nasal vaccines. Summary of the Invention

[0008] Compared to existing technologies, this invention addresses the characteristics of non-rinsing nasal medications or nasal vaccines using gel as a carrier. Through a temperature-controlled propulsion module, the temperature of the medication in the storage atomization structure is adjusted. Based on a preset dosage, the medication is pushed out from the storage atomization structure, completing the atomization. This enables quantitative and temperature-controlled output of gel-carrier medication and nasal spray-style atomization, resulting in excellent patient experience and therapeutic effects.

[0018] Furthermore, a metal conductor is provided between the cold end and the hot end of the cooling chip, and N-type semiconductors and P-type semiconductors made of bismuth telluride material are interleaved between the metal conductors.

[0024] During the user's medication administration process, the control module controls the motor in the following ways:

[0025] The dosage is converted into the number of rotations of the motor corresponding to the drug dispensing action; the motor is controlled to output the number of rotations at a preset speed, driving the propulsion component to uniformly push the drug from the drug storage atomization structure, thus completing the constant-speed and quantitative atomization of the drug.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0035] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0037] In the description of this application, it should be understood that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0039] Example 1

[0040] Currently, the researchers in this case have discovered that the use of non-rinsing nasal medications generally requires the patient to tilt their head back and squeeze the bottle to squeeze the liquid out of the bottle opening and drip it into the nasal cavity.

[0041] This drop-in method of medication administration limits the medication in the vial to a liquid state. For future medications or even nasal vaccines that may use gels as carriers, since gels are neither solid nor liquid, squeezing the gel out of the existing vial is more like squeezing toothpaste. The squeezed gel cannot detach from the vial opening in droplets, and it is easy to squeeze out a clump with just a little pressure. This is unacceptable for certain gel-based medications or nasal vaccines that may have strict requirements on dosage per administration in the future.

[0042] Furthermore, to maintain drug activity and efficacy, these gel-carrier drugs or nasal vaccines may have significant temperature restrictions, with potential differences between storage and usage temperatures. After a series of analyses, demonstrations, and tests, the researchers in this case ultimately provided the following solution:

[0043] A smart nasal spray, please refer to Figure 1 It includes an outer shell 1, a drug atomizing structure 2, a temperature-controlled propulsion module 3, a control module, and a power supply component 6 for power supply; wherein:

[0044] The drug storage atomizing structure 2 is located on the top of the outer shell 1; the temperature control propulsion module 3, the control module, and the power supply assembly are located inside the outer shell 1;

[0045] The temperature control propulsion module 3 is controlled by the control module and is used to adjust the temperature of the drug in the drug storage atomization structure 2, push the drug out of the drug storage atomization structure 2 in a preset dosage, and complete the constant temperature and quantitative atomization of the drug.

[0046] Compared to existing technologies, this application addresses the characteristics of non-rinse nasal medications or nasal vaccines using gel as a carrier, by employing a temperature-controlled propulsion module. (Please refer to [link / reference]). Figure 2 Adjust the temperature of the drug in the drug storage atomization structure. According to the preset dosage, please refer to [link / reference needed]. Figure 3 The drug is pushed out from the drug storage atomizing structure to complete the drug atomization; it can realize the quantitative and temperature-controlled output of gel carrier drugs and nasal spray-type atomized drug delivery, with excellent user experience and drug efficacy, filling the gap in gel-based nasal drug delivery methods and having considerable application prospects.

[0047] Figure 2 In the diagram, the black arrows indicate the direction of heat transfer. Figure 3 In the diagram, white arrows indicate the state before and after propulsion, while black arrows indicate the direction of propulsion.

[0048] Specifically, during the preparation phase, if the temperature-controlled propulsion module 3 retains the state of its previous use, the control module can activate the temperature-controlled propulsion module 3 to reverse its operation and reset it, retracting the temperature-controlled propulsion module 3 into the outer shell 1. After the reset is complete, the drug is added to the drug storage atomizing structure 2, the temperature and dosage are set, and the control module activates the temperature-controlled propulsion module 3 to adjust the drug temperature and run it in the forward direction, expelling excess air from the drug storage atomizing structure 2. Once the temperature-controlled propulsion module 3 is in place, it can be used.

[0049] In contrast, the intelligent nasal sprayer provided in this embodiment can be used not only for non-rinsing nasal medications with gel as a carrier, but also for liquid non-rinsing nasal medications, achieving the same effect of quantitative spraying and improving the user experience.

[0050] In a preferred embodiment, the system further includes a display panel 4 and a button assembly 5 for users to set parameters of the control module; the display panel 4 and the button assembly 5 are disposed in the housing 1.

[0051] The parameter settings include medication temperature; after receiving the medication preparation command initiated by the user, the control module detects the temperature of the drug in the drug storage atomization structure 2 through the temperature control propulsion module 3, and adjusts the temperature of the drug in the drug storage atomization structure 2 to the medication temperature.

[0052] For example, some pre-made gel nasal medications may only be stored at 2 to 6 degrees Celsius. To improve the efficacy of the medication and reduce irritation to the nasal cavity, the temperature of the medication can be appropriately increased. For some gel nasal medications that need to be prepared on-site, the gel temperature may still be relatively high when it is freshly prepared. It can be cooled down to avoid burning the nasal cavity during use and further improve the comfort of using the medication.

[0053] For details, please refer to Figure 4 The display component 4 may include a screen 41 and a screen glass 42 for protecting the screen 41; the button component 5 may include a PCB button board 51 with travel buttons and buttons 52 sleeved on the PCB button board 51, mainly realizing button functions such as power on, left and right selection, confirmation, settings and start.

[0054] Furthermore, the parameter settings include the total drug dosage;

[0055] After the user completes the drug preparation work for the drug storage atomizing structure 2: the control module obtains the remaining drug storage space according to the total drug dosage, and controls the temperature control propulsion module 3 to discharge the excess air in the drug storage atomizing structure 2 according to the remaining drug storage space, thus completing the positioning of the temperature control propulsion module 3.

[0056] Furthermore, the parameter settings include the number of times medication is administered;

[0057] If the medication is administered more than once, after the user initiates a medication command, the control module will not respond to subsequent medication commands initiated by the user within a preset silent period.

[0058] The above improvements can prevent continuous spraying caused by accidental touches by users.

[0059] The parameter settings also include the dosage. If the number of times the medication is taken is more than once, the dosage can be expressed as the dosage for a single dose.

[0060] Specifically, for gel-type nasal medications that require multiple administrations after being prepared by the drug storage atomization structure 2, the intervals between administrations may be as short as 30 minutes or as long as 3 to 4 hours. In order to ensure that the efficacy of the medication in the drug storage atomization structure 2 does not deteriorate when the medication is administered next time, some gel-type nasal medications can be kept cold by the temperature control propulsion module 3 through a drug storage command initiated by the user.

[0061] Therefore, in a preferred embodiment, the parameter settings also include drug storage temperature; after receiving the drug storage command initiated by the user, the control module detects the temperature of the drug in the drug storage atomization structure 2 through the temperature control propulsion module 3, and adjusts the temperature of the drug in the drug storage atomization structure 2 to the drug storage temperature.

[0062] More specifically, the usage process of the intelligent nasal spray in this embodiment may include:

[0063] The user resets the drug storage atomizing structure 2 and the temperature control propulsion module 3; prepares the drug storage atomizing structure 2; and sets the total drug dosage, number of doses, single dose, drug temperature, and drug storage temperature.

[0064] After the preparatory work is completed, the control module controls the temperature control propulsion module 3 to exhaust the drug storage atomization structure 2, adjust the drug in the drug storage atomization structure 2 to the medication temperature, and remind the user to start a single dose; after the user finishes a single dose, the control module controls the temperature control propulsion module 3 to maintain the drug at the drug storage temperature during the interval between doses, and readjusts the drug to the medication temperature before the next dose, and reminds the user.

[0065] After use, the user should clean, drain, and reset the drug storage atomizing structure 2 and the temperature control propulsion module 3.

[0066] As an optional embodiment, the power supply component 6 can be located at the bottom of the housing 1; the power supply component 6 includes a battery 61 and a charging power module 62; the battery 61 can be a lithium battery or other rechargeable battery; the charging interface of the charging power module 62 can be a USB Type-B or USB Type-C interface, or other existing interfaces; the charging interface can be provided with a dustproof silicone cover fixed to the housing 1, which can be opened when charging is needed. In addition, the charging interface can also integrate data exchange function to facilitate testing or setting of the smart nasal sprayer during maintenance.

[0067] Example 2

[0068] This embodiment can be considered a further extension and refinement of Embodiment 1, specifically: an intelligent nasal sprayer. Please refer to [link to relevant documentation]. Figure 1 as well as Figure 4 , Figure 5 It includes an outer shell 1, a drug atomizing structure 2, a temperature-controlled propulsion module 3, a control module, and a power supply component for power supply; wherein:

[0069] The drug storage atomizing structure 2 is located on the top of the outer shell 1; the temperature control propulsion module 3, the control module, and the power supply assembly are located inside the outer shell 1;

[0070] The temperature control propulsion module 3 is controlled by the control module and is used to adjust the temperature of the drug in the drug storage atomization structure 2, push the drug out of the drug storage atomization structure 2 in a preset dosage, and complete the constant temperature and quantitative atomization of the drug.

[0071] The temperature-controlled propulsion module 3 includes a propulsion component 31, a temperature-controlled component 32 controlled by the control module, and a motor 33;

[0072] One end of the propulsion component 31 is connected to the drug storage atomizing structure 2, and the other end is connected to the output end of the motor 33 for driving, so as to push the drug from the drug storage atomizing structure 2 out of the preset dosage.

[0073] The temperature control component 32 is disposed in the propulsion component 31 and is used to conduct heat through the propulsion component 31 to adjust the temperature of the drug in the drug storage atomization structure 2.

[0074] In a preferred embodiment, the temperature control component 32 includes a temperature-sensitive probe, a cooling element 322, a heat sink 323, and a cooling fan 324; the outer casing 1 is provided with heat dissipation holes 11; wherein:

[0075] The temperature-sensitive probe is used to monitor the temperature of the drug in the drug storage atomization structure 2; the cooling chip 322 is used to absorb the heat of the drug in the drug storage atomization structure 2 and discharge it through the heat sink 323, the cooling fan 324 and the heat dissipation hole 11.

[0076] The control module 9 can be a PCBA motherboard equipped with various necessary electronic components; as an optional embodiment, the control module 9 can be located in the middle of the outer casing 1, close to the cooling fan 324.

[0077] Furthermore, the propulsion component 31 includes a heat-conducting propulsion shell 311, a propulsion silicone 312, a propulsion support 313, and a fan compartment 314; wherein:

[0078] The propulsion silicone 312 is sleeved on the heat-conducting propulsion shell 311 and together with the heat-conducting propulsion shell 311, connects to the drug storage atomizing structure 2. It is used to seal the lower end of the drug storage atomizing structure 2 and squeeze out the air or drug in the drug storage atomizing structure 2 during the propulsion process. The propulsion support 313, the fan compartment 314, and the output end of the motor 33 are sequentially connected to the lower part of the heat-conducting propulsion shell 311.

[0079] The temperature-sensitive probe is disposed in the thermally conductive propulsion shell 311; the cold end of the cooling chip 322 is attached to the top surface of the inner side of the thermally conductive propulsion shell 311, and the hot end of the cooling chip 322 is attached to the heat sink 323; the heat sink 323 is disposed in the propulsion bracket 313, and the cooling fan 324 is disposed in the fan compartment 314.

[0080] Furthermore, the temperature control component 32 also includes a heating film 321; the heating film 321 is disposed on the side of the inner side of the heat-conducting propulsion shell 311 and is used to heat the drug in the drug storage atomization structure 2.

[0081] For further details, please refer to Figure 6 The cooling chip 322 has a metal conductor between its cold end and hot end, and N-type semiconductors and P-type semiconductors made of bismuth telluride material are interleaved between the metal conductors.

[0082] Specifically, the cold end and hot end of the cooling chip 322 can be made of insulators, or more specifically, ceramic chips can be used.

[0083] Furthermore, the heat-conducting propulsion shell 311 is made of stainless steel.

[0084] In a preferred embodiment, the motor 33 is a stepper motor with encoding function;

[0085] During the user's medication administration, the control module controls the motor 33 in the following ways:

[0086] The dosage is converted into the number of rotations of the motor 33 corresponding to the drug dispensing rotations; the motor 33 is controlled to output the number of rotations at a preset speed, driving the propulsion component 31 to uniformly push the drug from the drug storage atomization structure 2, thus completing the constant-speed and quantitative atomization of the drug.

[0087] Specifically, the encoder-integrated stepper motor is a device suitable for encoding signals (such as bit streams) or data on a motor and converting them into a signal form that can be used for communication, transmission, and storage.

[0088] In this embodiment, the output end of the encoder-equipped stepper motor is connected to the fan housing 314 via a thread-like structure. The fan housing 314 does not rotate with the output end of the encoder-equipped stepper motor; it is only lifted or retracted by the thread. This allows the propulsion component 31 and the temperature control component 32 to be propelled and retracted in a rotational and telescopic manner. When the encoder-equipped stepper motor is running in the forward direction, the heat-conducting propulsion shell 311 is propelled from the lower end to the upper end of the drug storage atomizing structure 2. When the encoder-equipped stepper motor is running in the reverse direction, the heat-conducting propulsion shell 311 is retracted from the upper end to the lower end of the drug storage atomizing structure 2. This enables the extrusion of the drug and the resetting of the equipment.

[0089] Using a stepper motor with an encoder as the power source firstly allows the signal encoding process to be streamlined; secondly, since the amount of drug extruded, or the advancing position of the propulsion component 31 and the temperature control component 32, is determined by the number of rotations of the stepper motor with the encoder (i.e., a larger number of rotations results in a larger extrusion amount, and vice versa), this rotary propulsion method means that the dosage can be set to 0.01 ml or even lower, improving the compatibility of this embodiment with various drugs through more refined output; furthermore, the output power of the stepper motor with the encoder is more controllable and stable under this propulsion method, which can further achieve uniform drug delivery.

[0090] As an optional embodiment, it may also include a voice prompt module controlled by the control module, and the housing 1 may also be provided with a sound outlet for the voice prompt module to be played externally.

[0091] Example 3

[0092] This embodiment can be considered a further extension and refinement of embodiment 1 or 2, specifically: an intelligent nasal sprayer. Please refer to [link to relevant documentation]. Figure 1 It includes an outer shell 1, a drug atomizing structure 2, a temperature-controlled propulsion module 3, a control module, and a power supply component for power supply; wherein:

[0093] The drug storage atomizing structure 2 is located on the top of the outer shell 1; the temperature control propulsion module 3, the control module, and the power supply assembly are located inside the outer shell 1;

[0094] The temperature control propulsion module 3 is controlled by the control module and is used to adjust the temperature of the drug in the drug storage atomization structure 2, push the drug out of the drug storage atomization structure 2 in a preset dosage, and complete the constant temperature and quantitative atomization of the drug.

[0095] The drug storage atomizing structure 2 may include a drug storage cylinder 21 and an atomizing cover 22;

[0096] The medicine storage cylinder 21 is located on the top of the outer shell 1; the atomizing cover 22 is detachably located on the top of the medicine storage cylinder 21.

[0097] Specifically, when the medicine storage cylinder 21 is located at the top of the outer shell 1, the medicine storage cylinder 21 and the temperature control propulsion module 3 can together form a container with a sealed bottom.

[0098] As an optional embodiment, the medicine storage cylinder 21 and the atomizing cap 22 may be provided with protrusions that are easy for a person to grip.

[0099] Furthermore, the medicine storage cylinder 21 may be equipped with a graduation mark.

[0100] Furthermore, the medicine storage cylinder 21 is provided with a thread for fixing to the outer shell 1, and the atomizing cover 22 is provided with a thread for fixing to the medicine storage cylinder 21; the loading and unloading direction of the medicine storage cylinder 21 on the outer shell 1 is opposite to the loading and unloading direction of the atomizing cover 22 on the medicine storage cylinder 21.

[0101] The above improvements enhance the ease of installation and removal of the drug storage atomizing structure 2. Furthermore, since the installation and removal directions are opposite—for example, the atomizing cover 22 opens to the left and the drug storage cylinder 21 opens to the right—the probability of accidental opening by the user can be reduced.

[0102] Furthermore, the atomizing cover 22 is provided with a tube, and the tube is provided with a spray atomizing plate.

[0103] Specifically, the temperature-controlled propulsion module 3 will squeeze the medicine in the medicine storage cylinder 21 and convert it from liquid to mist through the spray atomizing plate to achieve a spraying effect.

[0104] Furthermore, the drug storage atomizing structure 2 also includes a nasal intubation tube 23; the nasal intubation tube 23 is sleeved on the tube body; the nasal intubation tube 23 is a hollow umbrella-shaped structure that matches the shape of the nostrils.

[0105] Specifically, the nasal inhalation tube 23 is designed to contact the user's nostrils. Its hollow umbrella-shaped structure conforms to the nostrils, and the depth of insertion depends on the size of the nostrils. The middle section of the nasal inhalation tube 23 can be tubular, connecting to the tube body of the nebulizer cap 22 to form a complete delivery channel. The atomized medication is delivered into the user's nasal cavity through the tube body of the nasal inhalation tube 23, completing the nasal spray application. The nasal inhalation tube 23 can be available in various sizes to suit different user groups. Furthermore, the nasal inhalation tube 23 can be disposable, further improving ease of use and expanding its application scenarios.

[0106] The above descriptions are merely various embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
