Description

Technical Field

[0001] This invention relates to the field of medical auxiliary devices, and more particularly to a topical drug delivery device for shingles. Background Technology

[0002] Shingles is an infectious disease caused by the varicella-zoster virus. Unlike traditional skin diseases, the blisters caused by this virus are easily ruptured, and the internal fluid splashes or flows around the varicella when the blisters rupture, causing the surrounding skin or hands to become contaminated with this fluid. This fluid is highly infectious and can easily spread locally or infect others. Medications, whether liquid or ointment, need to be applied evenly to ensure full absorption. Current technologies typically use sprays or swabs for application. While sprays ensure even distribution, they are limited by the liquid nature and cannot be used with ointments. Swabs reduce the area covered by fingers, but still require hand application and a high degree of control from the operator. Patients with shingles often experience severe pain, especially in the lower back or back area, making self-administration difficult. To address these issues, a shingles application device is needed. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides the following technical solution: A shingles topical drug delivery device includes: a drug dispenser and a blower assembly disposed on one side of the drug dispenser.

[0004] Specifically, the bottom of the extrusion cylinder is connected to a drug outlet, and the extrusion cylinder squeezes to force the drug to be extruded in a rectangular, flat manner from the outlet of the drug outlet. The air outlet of the blower assembly is located on one side of the outlet of the drug outlet.

[0005] As an improvement to the above technical solution, the blower assembly has a medicine chamber on the side near the extrusion cylinder, and a drug delivery channel is provided on one side of the extrusion cylinder, with the other end of the drug delivery channel connected to the bottom of the medicine chamber.

[0006] As an improvement to the above technical solution, the inside of the extrusion cylinder is provided with a baffle plate, the upper end face of the baffle plate is on the same plane as the lower inner wall of the drug delivery channel, and the inside of the extrusion cylinder is provided with a stopper rod, the height of the drug delivery channel being equal to or less than the height of the piston at the end of the stopper rod.

[0007] As an improvement to the above technical solution, the adjustment component includes a T-shaped plate and a positioning frame. The T-shaped plate is disposed inside the drug delivery channel, and the protrusion of the T-shaped plate extends to the outside of the drug delivery channel and is connected to the positioning frame.

[0008] As an improvement to the above technical solution, the other side of the positioning frame has protrusions extending from both sides and fixed to the dispensing component. The dispensing component is located inside the extrusion cylinder with one end sealed and the other end open. The sealed end of the dispensing component has a sealing cavity. When the dispensing component rises to the highest position, the partition is inserted into the interior of the sealing cavity to close the sealing cavity.

[0009] As an improvement to the above technical solution, the extrusion cylinder and the drug chamber are provided with a side cavity on one side wall near the T-shaped plate. The two branches of the T-shaped plate located inside the drug delivery channel are connected to the side plates. When the positioning frame is raised to the highest position, the side plates are inserted into the side cavity to open the drug delivery channel.

[0010] As an improvement to the above technical solution, the dispensing component is a rectangular tube, with one end inserted into the inside of the extrusion cylinder and the other end located outside the extrusion cylinder. A sealing plug is provided inside the outer end of the dispensing component, and the end of the dispensing component inside the extrusion cylinder is located at the same level or below the drug delivery channel.

[0011] As an improvement to the above technical solution, the blower assembly has an air chamber inside, and a positioning frame is detachably installed inside the end of the air chamber away from the drug dispensing part, and a fan is fixed inside the positioning frame.

[0012] As an improvement to the above technical solution, a sealing plate is provided on the upper end face of the air cavity, a dustproof net is provided on the end face of the sealing plate, and a sealing plug is provided on the other end face of the sealing plate. The sealing plug is used to seal the end of the medicine cavity, and the dustproof net is placed on the end of the air cavity.

[0013] As an improvement to the above technical solution, an air passage is provided on the side of the air chamber away from the fan. The air passage extends from the connecting side of the air chamber to the outlet of the drug dispensing component, and the opening of the air passage is the same as the opening of the drug dispensing component.

[0014] The beneficial effects of this invention are: The medication can be dispensed from a fixed position by a specially designed dispensing device. Since the dispensing position is rectangular, the extruded medication can be spread out in a thin, flat layer. For ointment-type medications, this allows for even application. Then, an auxiliary blower component blows air onto the spread medication, using air pressure to make the medication adhere better to the skin, ensuring full contact with the skin. The blower only needs to control the wind speed and air pressure, which can prevent the chickenpox blisters from rupturing and effectively avoid the safety risks caused by manual operation.

[0017] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0018] Existing technologies typically employ sprays or swabs for application. While sprays ensure even distribution, they are limited by the liquid nature of the liquid and cannot be used with ointment-type medications. Swabs, although reducing the area covered by fingers, still require hand manipulation and a high degree of control from the operator. Patients with shingles often experience severe pain, particularly in the lower back or back, making self-administration difficult. To address these issues, a shingles application device needs to be designed.

[0019] The herpes zoster topical drug delivery device includes: a drug dispenser 10 and a blower assembly 30 disposed on one side of the drug dispenser 10.

[0020] Specifically, the bottom of the extrusion cylinder 10 is connected to the drug outlet 23. The extrusion cylinder 10 squeezes to force the drug to be extruded in a rectangular flat shape from the outlet of the drug outlet 23. The air outlet of the blower assembly 30 is located on one side of the outlet of the drug outlet 23.

[0021] The medication is temporarily stored in the squeezing tube 10 and squeezed out in a syringe-like manner when needed. The squeezed-out medication is discharged through the outlet of the medication dispensing component 23, and the discharged medication is in a rectangular, flat state. By controlling the width of the outlet of the medication dispensing component 23 to be slightly thin, a thin layer of medication can be ensured to avoid waste. During the application process, the blower component 30 blows air onto the surface of the thin layer, allowing the thin layer of medication to fully contact the skin, thereby ensuring the absorption effect of the medication. No physical objects other than the medication come into contact with the skin throughout the process, effectively avoiding the problem of chickenpox rupture caused by contact.

[0022] In the aforementioned technical solution, the drug is stored in the extrusion cylinder 10, which makes it inconvenient to control the relationship between the extrusion cylinder 10 and the dispensing component 23. In order to ensure the sealing effect when the drug is not in use, the following design is given in this embodiment: The blower assembly 30 has a medicine chamber 32 on the side near the extrusion cylinder 10, and a drug delivery channel 121 is provided on one side of the extrusion cylinder 10. The other end of the drug delivery channel 121 is connected to the bottom of the medicine chamber 32.

[0023] A drug cavity 32 is set on the side for temporary storage of drugs. The drugs are dispensed through the drug delivery channel 121. Since there is a horizontal bend between the drug cavity 32 and the drug delivery component 23, the sliding descent of the drugs due to their own weight is effectively avoided, thus preventing the leakage of drugs when not in use.

[0024] The aforementioned technical solution does not impose any restrictions on the structure of the drug dispensing component 23. In this embodiment, at least one design for the drug dispensing component 23 is provided: The dispensing component 23 is a rectangular tube, with one end inserted into the inside of the dispensing cylinder 10 and the other end located on the outside of the dispensing cylinder 10. The end of the dispensing component 23 located on the outside is provided with a sealing plug, and the end of the dispensing component 23 located inside the dispensing cylinder 10 is located at the same level or below the drug delivery channel 121.

[0025] This design structure allows the drug delivery component 23 to be discharged normally. In addition, the port flush with the drug delivery channel 121 can stop the piston inside the extrusion cylinder 10, preventing it from moving further down and providing a restriction on the piston. The sealing plug at its end is used to seal the opening, preventing any leakage of a small amount of drug inside the drug delivery component 23 and enhancing the sealing effect.

[0026] The design of the extrusion cylinder 10 in the aforementioned technical solution is not perfect. In this embodiment, a further design is provided: The inside of the extrusion cylinder 10 is provided with a partition 12. The upper end face of the partition 12 is on the same plane as the lower inner wall of the drug delivery channel 121. The inside of the extrusion cylinder 10 is provided with a stopper rod 11. The height of the drug delivery channel 121 is equal to or less than the height of the piston at the end of the stopper rod 11.

[0027] The internal partition 12 provides positional restriction for the stopper rod 11, preventing the stopper rod 11 from descending too far. This design also provides a locking function when not in use. When not in daily use, the piston can be directly blocked to ensure a closed state and prevent drug leakage from the drug chamber 32. When needed, the stopper rod 11 can be pulled up, and the whole unit can be tilted to allow the drug to flow out from the drug delivery channel 121.

[0028] In the aforementioned technical solution, the sealing of the drug delivery channel 121 is not perfect enough. In order to further enhance the sealing effect when idle, the following design is given in this embodiment: The adjustment assembly 20 includes a T-shaped plate 22 and a positioning frame 21. The T-shaped plate 22 is disposed inside the drug delivery channel 121, and the protrusion of the T-shaped plate 22 extends to the outside of the drug delivery channel 121 and is connected to the positioning frame 21.

[0029] The T-shaped plate 22 can be lowered when not in use to isolate the medicine chamber 32 from the extrusion cylinder 10. The positioning frame 21 can be connected to the outer wall of the extrusion cylinder 10 or the medicine chamber 32 by magnetic attraction. Only a small iron piece needs to be added at the corresponding height. A strong magnet can be set on the inner wall of the T-positioning frame 21 to ensure that it can be stably fixed after adsorption.

[0030] In the aforementioned technical solution, when reusing the drug inside the drug chamber 32, the entire device needs to be tilted and the drug dispensed by shaking. This operation is rather cumbersome. In this embodiment, the following design is further provided: The other side of the positioning frame 21 has protrusions extending on both sides and is fixed to the dispensing component 23. The dispensing component 23 is located inside the extrusion cylinder 10 with one end sealed and the other end open. The sealed end of the dispensing component 23 has a sealing cavity 231. When the dispensing component 23 rises to the highest position, the partition 12 is inserted into the interior of the sealing cavity 231 to close the sealing cavity 231.

[0031] When medication is needed, the positioning frame 21 is lowered to its lowest position, and the medication channel 121 is sealed by the T-plate 22. At this time, the medication is inside the extrusion cylinder 10. The medication is discharged normally by pushing, thus achieving the medication application function. After the medication is applied, it can be kept still to maintain the sealing effect. Due to the cooperation between the piston of the stopper rod 11, the T-plate 22 and other structures, a sealing effect is formed at the medication channel 121. When used again, the entire positioning frame 21 only needs to be lifted. Due to the magnetic adsorption effect, the positioning frame 21 is attracted and fixed. At this time, the internal T-plate 22 is opened, and the bottom sealing cavity 231 and the partition 12 are closed. At this time, pulling up the stopper rod 11 creates a negative pressure effect. The medication inside the medication cavity 32 is drawn into the extrusion cylinder 10. After the medication is drawn, the positioning frame 21 is pushed down again to seal the medication channel 121 again and open the sealing cavity 231. Then, the medication can be administered by pushing down the stopper rod 11.

[0032] In the aforementioned technical solution, the T-shaped plate 22 is connected only by a single central protrusion, which makes it easy for ointment to adhere to the inside and leak during connection analysis. In order to reduce the possibility of ointment leakage, the following design is given in this embodiment: The extrusion cylinder 10 and the medicine chamber 32 have a side cavity 122 on one side wall near the T-shaped plate 22. The two branches of the T-shaped plate 22 located inside the drug delivery channel 121 are connected to the side plate 221. When the positioning frame 21 is raised to the highest position, the side plate 221 is inserted into the side cavity 122 to open the drug delivery channel 121.

[0033] The arrangement between the side cavity 122 and the side plate 221 creates a separation. During drug extraction, the side plate 221 and the side cavity 122 form a closed loop, effectively preventing the drug from contacting the central protrusion and thus preventing leakage from the gap. When the two separate, because there is still an obstruction between the side plate 221 and the side cavity 122, only a very small amount of drug will enter through the gap. After sealing, this small amount of drug will be evenly flattened. Over long-term use, slight leakage may occur, but regular cleaning can prevent drug contamination. To further prevent leakage, an auxiliary sealing structure such as a rubber ring can be added to the connection point to enhance the sealing effect.

[0034] The aforementioned technical solution has basically perfected the structural design of the drug dispensing component 23, drug delivery channel 121, etc. In order to further improve this embodiment, the following design is given for the blower assembly 30: The blower assembly 30 has an air chamber 31 inside. A positioning frame 312 is detachably installed inside the end of the air chamber 31 away from the drug dispensing part 23. A fan 313 is fixed inside the positioning frame 312.

[0035] The main separation output is provided by the internally installed fan 313, and the airflow is blown out along the air chamber 31 to achieve the effect of wind pressure. In addition, the design of the blower assembly 30 also includes the following structure: A sealing plate 314 is provided on the upper end face of the air cavity 31, a dustproof net 315 is provided on the end face of the sealing plate 314, and a sealing plug 316 is provided on the other end face of the sealing plate 314. The sealing plug 316 is used to seal the end of the medicine cavity 32, and the dustproof net 315 is placed on the end of the air cavity 31.

[0036] The cavity is sealed by the corresponding sealing plate 314, and the dustproof net 315 inside provides dustproof effect for daily use. Together with the sealing plug 316 on the side, it seals the medicine chamber 32. It is best to open the medicine chamber 32 when drawing medicine to avoid closing it, which would cause excessive negative pressure inside, thereby affecting the sealing plug 316 and causing structural damage.

[0037] To further design the structure of the air cavity 31, the following structure is provided in this embodiment: An air passage 311 is provided on the side of the air chamber 31 away from the fan 313. The air passage 311 extends from the connecting side of the air chamber 31 to the outlet of the drug dispensing component 23. The opening of the air passage 311 is the same as the opening of the drug dispensing component 23.

[0038] By extending the airway 311 at its end, the airflow is guided to the outlet of the drug delivery part 23. This allows the drug to be squeezed by the airflow immediately after it is expelled, thus ensuring that the drug adheres tightly to the skin and is fully absorbed.

[0039] The above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to limit it. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
