Description

Technical Field

[0001] This invention belongs to the field of oral drug delivery technology, and particularly relates to an oral local drug delivery device. Background Technology

[0002] In the treatment of oral diseases, topical drug administration is a common and important method, allowing medication to be applied directly to the affected area, improving drug utilization and reducing the side effects of systemic medication. However, traditional methods of topical oral drug administration, such as applying with cotton swabs or spraying with a spray bottle, have several shortcomings:

[0003] On the one hand, the drug delivery accuracy and uniformity are poor, making it difficult to ensure that the drug covers the entire target area, especially for the complex structure of the oral cavity;

[0004] On the other hand, traditional methods often lack the technical means to promote drug penetration, causing the drug to remain only on the surface and fail to penetrate deep into the tissue to exert its effects, thus affecting the treatment effect.

[0005] In addition, existing oral drug delivery devices are often single-function and cannot flexibly switch the delivery method (such as spray or smear) according to different treatment needs. They are also inconvenient to operate, have poor hygiene, and are prone to cross-infection.

[0006] To address the aforementioned issues, there is an urgent need for an oral local drug delivery device that can accurately deliver drugs, promote deep drug penetration, and offer multiple delivery modes to improve treatment efficiency and patient experience, thereby meeting clinical needs. Utility Model Content

[0007] The purpose of this invention is to provide a local oral drug delivery device to solve the problems of low drug delivery accuracy, poor penetration, limited functionality, and inconvenient operation in traditional oral drug delivery methods. By integrating spray and smear delivery modes and combining ultrasonic vibration and airflow-assisted technology, it achieves precise and uniform drug delivery and deep tissue penetration, thereby improving treatment efficacy and patient experience.

[0008] To achieve the above objectives, the specific technical solution of this utility model is as follows: an oral local drug delivery device, including a handle, wherein an ultrasonic generator is installed on the right side of the inner cavity of the handle to generate a high-frequency vibration signal during oral drug delivery, thereby promoting drug release and deep tissue penetration;

[0009] A power supply interface is installed at the right end of the handle. A plug is fitted into the upper side of one end of the power supply interface, and a conductive element is embedded in the middle of the surface of the power supply interface to provide power support and ensure the normal operation of the equipment.

[0010] Meanwhile, a spray drug delivery component and a smear drug delivery component are respectively installed at the input end of the power supply interface.

[0013] Preferably, an air pump is installed on the right side of the handle end, and the output end of the air pump is connected to an air pipe;

[0014] The plug has a magnetic cavity on the side away from the handle, and the inner surface of the magnetic cavity is inlaid with a magnet.

[0015] Preferably, the spray drug delivery assembly includes a plug socket and an ultrasonic wave guide plate fitted into the inner surface of the plug socket, and a plug is installed on the left side of the plug socket.

[0016] Preferably, a magnetic element is embedded at the bottom of the plug socket near the plug end, and the magnetic element is inserted into the magnetic cavity and attracted to the magnet.

[0025] The oral local drug delivery device of this invention has the following advantages:

[0026] This oral local drug delivery device utilizes a suction pump installed inside the handle to draw medication from a reservoir through a suction tube to an outlet tube. The medication is then delivered to the target area via a spray or swab delivery assembly. The spray assembly uses a high-frequency vibration signal generated by an ultrasonic generator, transmitted through an ultrasonic guide plate to a vibrating rod, which in turn vibrates the swab head to aid drug penetration and massage the affected area. Simultaneously, an air pump delivers gas through an air tube into a telescopic cover, which, in conjunction with the swab head, ensures uniform drug distribution. The swab delivery assembly uses a microporous atomizing plate to ultrasonically atomize the medication, and combined with the airflow from the air pump, blows the atomized medication through a spray mesh, forming uniform drug particles that cover the affected area. Both delivery methods are connected via a power interface and plug, a magnetic clasp (either magnetic clasp one or two), and conductive components. This allows for flexible selection of spray or swab delivery based on needs, achieving precise and uniform drug delivery, improving treatment effectiveness and patient experience.

[0044] To better understand the purpose, structure, and function of this utility model, the following detailed description of an oral local drug delivery device is provided in conjunction with the accompanying drawings.

[0045] like Figures 1-10 As shown, the present invention provides a local oral drug delivery device, including a handle portion 100, an assembly cylinder 120 integrally formed at the lower end of the handle portion 100, and a liquid storage cylinder 130 movably installed in the inner cavity of the assembly cylinder 120.

[0046] In specific implementation, the assembly cylinder 120 and the liquid storage cylinder 130 can be set according to the specific situation. For example, the assembly cylinder 120 and the liquid storage cylinder 130 can be connected by a thread at one end; or the assembly cylinder 120 can be snapped into the liquid storage cylinder 130.

[0047] A suction pump 200 is bolted to the end of the inner cavity of the handle 100, and the output end of the suction pump 200 is connected to an outlet pipe 210, such as... Figure 1As shown, at the same time, the input end of the suction pump 200 is connected to the suction tube, and the inlet of the suction tube passes through the assembly cylinder 120 and extends into the inner cavity of the storage cylinder 130.

[0048] With the cooperation of the suction pump 200, the suction tube and the outlet tube 210, the suction pump 200 pressurizes the liquid in the storage cylinder 130 and delivers it into the spray drug delivery component 600 or the smear drug delivery component 700, and then delivers the liquid into the user's mouth.

[0049] An ultrasonic generator 300 is installed on the right side of the inner cavity of the handle 100 to generate high-frequency vibration signals during oral administration, thereby promoting drug release and deep tissue penetration.

[0050] Specifically, when the ultrasonic generator 300 is working, it generates high-frequency vibration signals, which are transmitted to the target area through the module to promote drug release and deep tissue penetration.

[0051] An air pump 400 is installed on the right side of the end of the handle 100. The air pump 400 provides airflow assistance to help the atomized drug particles diffuse evenly to the target area, ensuring a wider and more uniform drug coverage.

[0052] like Figures 1 to 5 As shown, the output end of the air pump 400 is connected to an air pipe, which is used in conjunction with the spray drug delivery assembly 600. The output end of the air pipe is connected to the air inlet end of the telescopic cover 640. After the air pump 400 is powered, it pressurizes the gas and sends it into the telescopic cover 640 through the air pipe. The gas then passes through the opposite side of the gooseneck tube 731 and the connecting pipe 741 and is sent into the spray shell 750. The gas then enters the inner cavity of the inner spray cover 760 through the air spray mesh 781, blowing the drug liquid atomized by the microporous atomizing plate 770 outward.

[0053] A power supply interface 500 is installed on the right end of the handle 100. A plug 510 is fitted on the upper side of one end of the power supply interface 500, and a conductive element 520 is embedded in the middle of the surface of the power supply interface 500 to provide power to the spray drug delivery component 600 and the smear drug delivery component 700 to ensure the normal operation of the equipment.

[0054] A magnetic cavity 530 is formed on the surface of the plug 510 away from the handle portion 100, and a magnet is embedded in the inner surface of the magnetic cavity 530. The magnet is used in conjunction with magnetic component 620 and magnetic component 720. The size of magnetic component 620 and magnetic component 720 is slightly smaller than the diameter of the inner cavity of the magnetic cavity 530. When the magnet is used in conjunction with magnetic component 620, the spray drug delivery component 600 can be connected to the power supply interface 500 and installed on the handle portion 100. When the magnet is used in conjunction with magnetic component 720, the application drug delivery component 700 can be connected to the power supply interface 500 and installed on the handle portion 100.

[0055] Meanwhile, a spray drug delivery component 600 and a smear drug delivery component 700 are respectively provided at the input end of the power supply interface 500. The spray drug delivery component 600 and the smear drug delivery component 700 apply or atomize the drug through different delivery methods to accurately and evenly apply the drug to the target area, thereby improving the treatment effect and patient experience.

[0056] The spray drug delivery assembly 600 includes a plug socket 610 and an ultrasonic wave guide plate 630 fitted into the inner surface of the plug socket 610. A plug 611 is installed on the left side of the plug socket 610, and the plug 611 is used in conjunction with the plug 510. When the plug 611 is inserted into the plug 510, it is used to supply power to the spray drug delivery assembly 600.

[0057] The ultrasonic guide plate 630 transmits the vibration energy generated by the ultrasonic generator 300 to the microporous atomizing plate 770, thereby enhancing the drug release efficiency and penetration effect.

[0058] A magnetic element 620 is embedded in the bottom of the plug socket 610 near the plug 611, and the magnetic element 620 is inserted into the magnetic cavity 530 and attracted to the magnet.

[0059] A conductive disk 631 is fitted into the middle of the left side of the plug socket 610. The conductive disk 631 is electrically connected to the ultrasonic wave guide 630. When the magnetic suction member 620 is inserted into the ultrasonic wave guide 630, and the plug socket 610 and the power supply interface 500 are in contact with each other, the conductive member 520 is electrically in contact with the conductive disk 631, so as to use the conductive disk 631 and the conductive member 520 to supply power to the ultrasonic wave guide 630.

[0060] A telescopic cover 640 is installed on the right side of the plug socket 610. The telescopic cover 640 can be extended to a certain length. The output end of the liquid outlet tube 210 and the input end of the telescopic cover 640 are connected to each other so that the medicine can be delivered into the telescopic cover 640. The output end of the telescopic cover 640 is connected to the gooseneck tube 650, and the output end of the gooseneck tube 650 is connected to the ball cover 654. The telescopic cover 640, the gooseneck tube 650 and the ball cover 654 are connected to each other.

[0061] Specifically, the gooseneck tube 650 can be bent arbitrarily and its direction can be determined;

[0062] The inner cavity of the ball cover 654 is movably mounted with an applicator ball head 670, and the outer surface of the applicator ball head 670 is rotatably mounted to the inner cavity of the ball cover 654. The applicator ball head 670 exposed on one side of the ball cover 654 is used to apply to the affected area of ​​the user's mouth.

[0063] The inner cavities of the telescopic cover 640 and the gooseneck tube 650 are connected to a vibrating rod 660. One end of the vibrating rod 660 is connected to the surface of the ultrasonic guide plate 630, while the other end is connected to the surface of the application ball head 670. In this way, when the ultrasonic guide plate 630 vibrates, the high-frequency vibration can be transmitted through the vibrating rod 660 to the end of the application ball head 670, which helps the drug penetrate and also provides a slight massage effect on the affected area, relieving inflammation and pain.

[0064] Finally, when the plug socket 610 and the power supply interface 500 are in contact, the plug 611 is inserted into the plug 510, and the magnetic suction component 620 is inserted into the magnetic suction cavity 530. At the same time, the conductive disk 631 is connected to the conductive component 520 to supply power to the ultrasonic guide plate 630 and drive the vibrating rod 660 to vibrate. When it vibrates, it can shake and send the liquid medicine that has entered the telescopic cover 640 into the gooseneck tube 650. At the same time, the vibration of the vibrating rod 660 can drive the application ball head 670 to vibrate. When the application ball head 670 is used, the liquid medicine can be easily applied to the user's affected area and can help the medicine penetrate into the user's affected area.

[0065] The application drug delivery assembly 700 includes a plug socket 710 and a microporous atomizing plate 770. The microporous atomizing plate 770 is connected to the plug of the plug socket 711 via a cable. The cable on the microporous atomizing plate 770 is located in the inner cavity of the inner spray cover 760 and the spray shell 750, the gooseneck tube 731 and the connecting pipe 741, the telescopic cover 730 and the telescopic cover 740 on the opposite side. When the gas drawn in by the air pump 400 is blown into the telescopic cover 740, it can not only be blown into the microporous atomizing plate 770 through the spray shell 750 and the air spray mesh 781, but also the gas can be used to cool the cable.

[0066] A plug 711 is installed on one end of the plug socket 710, and the plug 711 and the plug 510 are movably connected. A magnetic component 720 is installed on the bottom of the surface of the plug socket 710, and the magnetic component 720 is inserted into the magnetic cavity 530 and used in conjunction with a magnet.

[0067] A telescopic cover 730 is installed on the right side of the plug socket 710. The inner cavity of the telescopic cover 730 is provided with a telescopic cover 740. The input end of the telescopic cover 740 is connected to the output end of the liquid outlet pipe 210. The input end of the telescopic cover 730 is connected to the air pipe output end of the air pump 400. This is used to send gas into the telescopic cover 730 through the air pipe, while the liquid medicine is pumped into the telescopic cover 740 through the liquid suction pump 200 and the liquid outlet pipe 210.

[0068] The output end of the telescopic cover 2 730 is connected to the gooseneck tube 2 731, while the output end of the telescopic cover 3 740 is connected to the connecting pipe 741.

[0069] The output ends of the gooseneck tube 731 and the connecting pipe 741 are respectively connected to the spray housing 750 and the inner spray hood 760. The inner spray hood 760 is installed into the inner cavity of the spray housing 750, such as... Figure 10 As shown, the microporous atomizing plate 770 is installed at the tail end of the inner cavity of the spray housing 750 and contacts the output end of the inner spray cover 760. One end of the inner cavity of the inner spray cover 760 is connected to a conical guide shell 780, and the tail end of the conical guide shell 780 contacts the surface of the microporous atomizing plate 770. Figure 10 As shown, the surface of the conical guide shell 780 is provided with air jet mesh 781, which allows gas to be blown into the microporous atomizing plate 770 through the air jet mesh 781. The microporous atomizing plate 770 uses ultrasonic vibration to atomize the liquid medicine delivered through the inner spray cover 760 into micron-sized particles, while the gas blows the atomized liquid medicine from the microporous atomizing plate 770 outward through the air jet mesh 781 and blows it into the user's affected area for application of medicine.

[0070] With the help of the application and spray application components 700 and 600, different methods can be used to apply medication to the patient's oral wounds, ensuring that the medication is applied precisely and evenly to the target area, thereby improving the treatment effect and patient experience.

[0071] The working principle of a local oral drug delivery device: This device uses a suction pump 200 installed inside the handle 100 to draw the liquid medication from the reservoir 130 through the suction tube to the outlet tube 210. The medication is then delivered to the target area via a spray delivery component 600 or an application delivery component 700. The spray delivery component 600 utilizes a high-frequency vibration signal generated by an ultrasonic generator 300, which is transmitted through an ultrasonic guide plate 630 to a vibrating rod 660, causing the application ball head 670 to vibrate to aid drug penetration and massage the affected area. Simultaneously, an air pump 400 delivers gas through an air tube into a telescopic cover 640 and through a gooseneck... The neck tube 650 works in conjunction with the ball cover 654 to achieve uniform distribution of the drug solution; while the application drug delivery component 700 uses a microporous atomizing plate 770 to ultrasonically atomize the drug solution, and combined with the airflow provided by the air pump 400, blows the atomized drug solution out through the jet mesh 781 to form uniform drug particles covering the affected area. Both drug delivery methods are connected to the power supply through the power interface 500 and the plug 510, magnetic component 620 or magnetic component 720 and the conductive component 520, so as to flexibly select the spray or application method according to the needs, achieve precise and uniform drug delivery, and improve the treatment effect and patient experience.
