Description

Technical Field

[0001] This invention relates to the field of nasal care technology, specifically to a portable nasal compress device. Background Technology

[0002] Nasal wet compresses are a local physical therapy and drug delivery method for dry, damaged, or inflamed nasal mucosa. Its core purpose is to continuously and stably deliver moisture, electrolytes, or specific medications to the nasal mucosa to maintain mucosal moisture, repair damaged epithelium, reduce inflammation, and mimic a healthy physiological environment. Nasal mucosal dryness is common in atrophic rhinitis, dry rhinitis, the recovery period after nasal endoscopy, or in environments such as air conditioning or dry climates, manifesting as nasal dryness, pain, burning, crusting, and even bleeding. Effective wet compresses not only directly relieve discomfort but, more importantly, maintain the normal clearance function of the mucosal cilia, preventing secondary infections, and are a crucial part of basic nasal care and disease treatment.

[0003] Currently, routine nursing care for nasal mucosal dryness, postoperative repair, or chronic inflammation often involves using nasal cotton pads or gauze strips for wet compresses or medication administration. Early dressings, primarily made with petrolatum-oiled gauze strips, were widely used, followed by the development of ordinary medical cotton pads and herbal-infused gauze strips. Traditionally, medical staff apply or spray medication directly onto the cotton pad / gauze strip and then insert it into the patient's nasal cavity using instruments such as nasal endoscopes or anterior rhinoscopes. However, these cotton pads have a simple structure, and the method of pouring medication onto the pad makes medication release uncontrollable. For example, when inserting the pad into the nasal cavity after pouring medication, the pressure from the nasal cavity walls can easily cause the medication to drip out onto the patient's skin at the philtrum, leading to cross-contamination or waste of medication, resulting in local irritation or poor therapeutic effect. Therefore, there is an urgent need for a new type of portable nasal wet compress device that can uniformly and slowly release medication and can be safely removed. Summary of the Invention

[0004] To address the aforementioned issues, this invention provides a portable nasal compress device. By embedding a drug-injection component inside a cotton pad and releasing the medication by pulling it out, the medication is completely released inside the nasal cavity, reducing the risk of medication spillage.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: A portable nasal wet compress device includes a cotton pad, which comprises a cotton layer, a hydrogel layer, and a functional cavity from the outside to the inside. The hydrogel layer has several through holes, and the functional cavity is provided with an injection component for injecting and releasing a temporarily stored drug solution. The functional cavity has a flat, inverted trapezoidal structure. The cotton pad has a pull strip, one end of which extends through the cotton layer into the functional cavity. The pull strip is provided with a support component for providing rigid support. One end of the pull strip located in the functional cavity is hinged with a symmetrically arranged first protrusion and a second protrusion. The first protrusion is hollow, and the end of the first protrusion away from the pull strip is sleeved on the outside of the second protrusion. The hydrogel layer is located between the pull strip and the cotton layer, and the injection component is located between the first protrusion and the second protrusion.

[0006] The technical principles of the above solution are as follows:

[0007] The cotton pad is placed inside the patient's nasal cavity. The functional cavity is designed in a flat, inverted trapezoidal shape to fit the nasal cavity space. Pulling the external pull strip causes relative movement between the first and second protrusions hinged to it. Simultaneously, because the functional cavity within the hydrogel layer is inverted trapezoidal, it limits the relative position of the first and second protrusions. Therefore, the distance between the first and second protrusions decreases as the pulling distance increases. Furthermore, since the first protrusion fits over the second protrusion, the gap between them decreases, thereby releasing the medication from the infusion component through compression. The released medication can penetrate through the pores in the hydrogel layer to the outer cotton layer, ultimately acting on the nasal mucosa to achieve the purpose of wet compress or drug delivery. Simultaneously, the hydrogel layer and cotton layer soften under the influence of the medication, allowing the cotton pad to be completely removed from the patient's nasal cavity after the wet compress is completed, using the pull strip.

[0008] The above approach has the following beneficial effects:

[0009] 1. This solution allows for deployment and drug release within the body simply by operating the pull bar. It simplifies the cumbersome process of traditionally soaking the drug before placing it into the patient's nasal cavity by directly squeezing the injection component after insertion into the nasal cavity. This significantly improves the convenience and immediacy of use and avoids drug loss or contamination during the storage and retrieval of the pre-soaked dressing.

[0010] 2. This solution utilizes a mechanical structure that links a pull strip to internal protrusions to achieve controllable triggering of the drug delivery component. This mechanical activation method is controllable and reliable, ensuring that the medication is released only after the dressing is positioned correctly in the nasal cavity, achieving precise on-demand drug delivery. Simultaneously, the pores on the hydrogel layer form channels for the slow release of medication into the cotton layer, facilitating even drug diffusion, preventing excessively high local concentrations, and improving the uniformity and comfort of the wet compress.

[0011] 3. In this design, the flat, inverted trapezoidal structure of the functional cavity better conforms to the anatomical shape of the nasal cavity, reducing the feeling of a foreign body. The design of the pull strip and its internal support components provides the necessary rigid support and force transmission path for operation within the narrow nasal cavity space.

[0012] Furthermore, the support assembly includes a support rod disposed hollow within the pull bar, and the support rod has an injection channel inside.

[0013] Beneficial effects: The hollow support rod provides the necessary operational rigidity for the pull strip, while the internal injection channel offers a precise path for subsequent medication replenishment or replacement. This design allows for access to the injection component via external injection devices without damaging the overall structure of the cotton pad, achieving adjustable dosage and flexible formulation during treatment.

[0014] Furthermore, the injection component includes a bursting bead, the outer shell of which is made of gelatin, and the bursting bead is fixedly connected to one end of the pull strip located within the functional cavity.

[0015] Beneficial effects: Using gelatin-shelled capsules for storing the medication solution achieves dry-wet separation between the medication solution and the dressing substrate, ensuring the product's stability during storage.

[0016] Furthermore, both the first and second protrusions are made of double cross-linked alginate hydrogel, and the gap between the first and second protrusions is in contact with the outer wall of the popping bead.

[0017] Beneficial effects: The double cross-linked alginate hydrogel material gives the bumps suitable elasticity and flexibility, so that when the first and second bumps are attached to the outer wall of the bursting bead, they can not only generate effective clamping force, but also buffer some stress through their own deformation during the pressure process, avoiding excessively sharp impact on the bursting bead, thus making its breakage more controllable.

[0018] Furthermore, several spiral grooves are provided at the connection between the hydrogel layer and the pull strip, and the pull strip is provided with a slider that slides in accordance with the grooves.

[0019] Beneficial effects: The combination of the spiral groove and the slider transforms the user's linear pulling force on the pull bar into a combination of rotation and linear motion, making the process of triggering the popping bead more stable and gradual. This prevents the popping bead from breaking irregularly or causing unexpected traction on the nasal cavity due to sudden linear pull, thus improving the controllability of the operation.

[0020] Furthermore, a sealing plug is provided at the end of the injection channel near the burst bead.

[0021] Beneficial effects: The sealing plug is located at the end of the injection channel. When it is necessary to inject liquid into the burst bead, it can provide a puncture target for the needle, and after the needle is pulled out, it can rely on its own elasticity to close the channel again and maintain the seal.

[0022] Furthermore, the hydrogel layer and functional cavities are distributed on the cotton pad in a 2cm*2cm specification, the pull strip is detachably connected to the cotton pad, and the cotton pad is etched with corresponding cutting lines.

[0023] Beneficial effects: Medical staff can cut cotton pads to the required size and shape according to the specific condition of the patient's nasal cavity, such as the size of the surgical cavity and the extent of the lesion, thus achieving individualized dressing adaptation.

[0024] Furthermore, the hydrogel layer is made of a temperature-sensitive hydrogel material.

[0025] Beneficial effects: During wet compresses, the softened hydrogel can better conform to the complex curves of the nasal mucosa, improving comfort.

[0026] Furthermore, a pull ring is provided at the end of the pull bar that is away from the functional cavity.

[0027] Beneficial effect: The pull ring provides medical staff with an easy point of operation to apply force, making the pulling operation easier to perform.

[0028] Furthermore, the medication injected into the capsule through the injection channel contains a mixture of sodium hyaluronate, physiological seawater concentrate, and vitamin B5.

[0029] Beneficial effects: Sodium hyaluronate provides powerful and long-lasting moisturizing and lubrication; physiological seawater concentrate regulates osmotic pressure, provides trace elements, and gently cleanses; vitamin B5 helps promote the repair of mucosal cells. The combination of these three ingredients achieves multiple benefits of moisturizing, cleansing, and repair, meeting the comprehensive treatment needs of post-nasal surgery care or dry, inflamed conditions.

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

[0037] The following detailed description illustrates the specific implementation method:

[0038] Example:

[0039] Currently, routine nursing care for nasal mucosal dryness, postoperative repair, or chronic inflammation often involves wet compresses or medication administration using nasal cotton pads or gauze strips. The traditional method typically involves directly dripping or spraying the medication onto the cotton pad / gauze strip, then inserting it into the patient's nasal cavity using instruments such as a nasal endoscope. This method has several inherent drawbacks: First, the pre-soaked cotton pads are prone to evaporation or contamination of the medication during storage and use, and the dosage cannot be precisely controlled or adjusted. Second, the distribution of the medication on the cotton pad is often uneven, potentially leading to excessively high or low local drug concentrations in the nasal cavity, affecting efficacy and possibly causing irritation.

[0040] Therefore, based on the problems of uncontrollable drug storage and release and inconvenient dressing use in the prior art, the inventors proposed the following... Figure 1 A portable nasal compress device is shown, comprising cotton pads 1, such as... Figure 2As shown, the cotton pad 1 includes a cotton layer 5, a hydrogel layer 6, and a functional cavity from the outside to the inside. The hydrogel layer 6 and the functional cavity are distributed on the cotton pad 1 in a 2cm*2cm specification. The pull strip 2 is detachably connected to the cotton pad 1. The cotton pad 1 is etched with corresponding cutting lines 3. After the patient completes the nasal endoscopy surgery, the nurse takes out the cotton pad 1 and can selectively cut off 1.2cm or 1.8~2cm pieces of the cotton pad 1 along the cutting lines 3 and insert them into the patient's nasal cavity.

[0041] Hydrogel layer 6 is made of temperature-sensitive hydrogel material, and several through-holes 7 are formed on hydrogel layer 6, such as... Figure 2 As shown, the functional cavity is equipped with a drug injection component for injecting and releasing the temporarily stored drug solution. The functional cavity has a flat inverted trapezoidal structure. The cotton pad 1 is provided with a pull strip 2. One end of the pull strip 2 extends through the cotton layer 5 into the functional cavity, and the end of the pull strip 2 away from the functional cavity is provided with a pull ring 4.

[0042] The injection assembly includes a bursting bead 9, the outer shell of which is made of gelatin. The medication entering the bursting bead 9 through the injection channel 12 contains a mixture of sodium hyaluronate, physiological seawater concentrate, and vitamin B5. The bursting bead 9 is fixedly connected to one end of the pull bar 2 located within the functional cavity. The pull bar 2 is equipped with a support assembly providing rigid support. This support assembly includes a hollow support rod 11 disposed within the pull bar 2, and the support rod 11 contains an injection channel 12. A sealing plug is located at the end of the injection channel 12 near the bursting bead 9. Align the syringe needle with the injection channel 12 of the inner support rod 11 of the pull bar 2. Advance the needle along the injection channel 12 and pierce the sealing rubber stopper. At this time, the injection channel 12 provides precise guidance for the needle, preventing the needle from deviating and damaging the device components. Then, inject the mixed medicine into the bursting bead 9. After the injection is completed, pull out the needle. The sealing rubber stopper automatically springs back to seal the injection channel 12, preventing the medicine from leaking out prematurely. This design solves the problem that the existing cotton pad 1 cannot accurately replenish the medicine and the medicine is easily lost prematurely. Moreover, the medicine can be added without disassembling the device, making the operation convenient.

[0043] One end of the pull bar 2 located within the functional cavity is hinged to a symmetrically arranged first protrusion 10 and second protrusion 8. The first protrusion 10 is hollow, and the end of the first protrusion 10 furthest from the pull bar 2 is sleeved onto the outside of the second protrusion 8. Figure 3As shown, both the first protrusion 10 and the second protrusion 8 are made of double-crosslinked alginate hydrogel, and the gap between the first protrusion 10 and the second protrusion 8 fits snugly against the outer wall of the burst bead 9, effectively limiting the displacement of the burst bead 9 within the functional cavity. Simultaneously, the double-crosslinked alginate hydrogel material has excellent biocompatibility, will not react with the medication, and will not irritate the nasal mucosa. The hydrogel layer 6 is located between the pull strip 2 and the cotton layer 5, and the medication injection component is located between the first protrusion 10 and the second protrusion 8. Several spiral grooves are formed at the connection between the hydrogel layer 6 and the pull strip 2, and the pull strip 2 is equipped with sliders that slide in conjunction with the grooves.

[0044] When cotton pad 1 is placed inside the patient's nasal cavity, it is in its initial state. The temperature-sensitive hydrogel layer 6 does not soften upon contact with body temperature, maintaining a certain structural strength and providing support for the entire device. This facilitates the patient's insertion of cotton pad 1 into the nasal cavity. The hydrogel layer 6 is located between the pull strip 2 and the cotton layer 5. As the component that directly contacts the nasal mucosa, the soft texture of cotton layer 5 reduces frictional damage to the fragile mucosa after surgery. Compared to existing ordinary cotton pads 1, the cotton layer 5 in this design achieves stable placement through the support of the hydrogel layer 6, avoiding local pressure caused by lack of support when directly contacting the mucosa. The hydrogel layer 6 gradually softens upon contact with the nasal cavity at approximately 37°C, initially providing a moisturizing effect. At the same time, the numerous pores 7 on the hydrogel layer 6 remain permeable, providing channels for subsequent medication penetration. Once the cotton pad 1 is in place, the nurse gently pulls the pull ring 4 outwards. The pull ring 4 drives the pull bar 2 to move outwards. The slider on the pull bar 2 slides smoothly along the spiral groove at the connection of the hydrogel layer 6. The design of the spiral groove and the slider can prevent the pull bar 2 from deviating during the pulling process, ensuring that the pulling force is evenly transmitted to the popping bead 9 in the functional cavity.

[0045] As the pull bar 2 moves, and because the hydrogel layer 6 is inverted trapezoidal, the inner wall of the hydrogel layer 6 acts as a limit for the first protrusion 10 and the second protrusion 8, such as... Figure 2As shown, the first protrusion 10 and the second protrusion 8, which are hinged to each other, gradually mesh with each other under the action of tension. Since the first protrusion 10 is a hollow structure and is sleeved on the outside of the second protrusion 8, the two form a squeezing force on the bursting bead 9 during the meshing process. Moreover, the elastic properties of the double cross-linked alginate hydrogel can make the protrusion and the outer wall of the bursting bead 9 fit tightly, so as to achieve precise crushing of the bursting bead 9 and avoid the problem that the bursting bead 9 is displaced and cannot be broken or is not broken completely, resulting in the inability to release the medicine. The outer shell of the burst bead 9 is made of gelatin. Upon rupture, the internal mixture of sodium hyaluronate, concentrated physiological seawater, and vitamin B5 rapidly flows out. At this point, the perforations 7 on the hydrogel layer 6 play a crucial role. The medication seeps into the cotton layer 5 in an orderly fashion through the perforations 7, rather than rapidly filling the cotton layer 5. This effectively controls the penetration rate, allowing the cotton layer 5 to evenly absorb the medication and continuously act on the nasal mucosa. This solves the defects of uneven medication distribution and excessively rapid diffusion in existing cotton pads 1. Simultaneously, the perforations 7 isolate the gelatin fragments generated after the burst bead 9 ruptures, preventing them from flowing into the cotton layer 5 and contacting the nasal mucosa, thus avoiding irritation or infection. During this process, because the hydrogel layer 6 and cotton layer 5 are not yet fully soaked and softened by the extracted medication, they provide some support within the patient's nasal cavity. When external force pulls the strip 2, the friction between the entire cotton pad 1 and the nasal cavity is relatively high, preventing the cotton pad 1 from being completely pulled out, allowing it to remain inside the nasal cavity and receive continuous medication penetration.

[0046] During the continuous penetration of the medication, the temperature-sensitive hydrogel layer 6 softens completely, further enhancing the softness and adhesion of the cotton layer 5. This allows the cotton layer 5 to closely conform to the curved surface of the nasal mucosa, ensuring that the medication fully acts on the dry areas and promotes mucosal repair. Simultaneously, the hydrogel layer 6 itself has moisturizing and water-locking functions, prolonging the duration of the medication's effect. Compared to the existing cotton pads 1, which have short application time and poor moisturizing effect, this solution provides long-lasting care. After the wet compress is completed, the nurse gently pulls the pull ring 4 again. At this point, the hydrogel layer 6 is completely softened, and the cotton layer 5, having absorbed the medication, is soft and will not stick to the nasal mucosa. The cotton pad 1 can be smoothly removed by pulling the strip 2, avoiding secondary mucosal damage caused by dryness and adhesion when removing existing nasal cotton pads.

[0047] 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.
