Description

Technical Field

[0001] This utility model relates to the technical field of local drug delivery devices for oral medicine treatment, and more particularly to a local drug delivery device for oral medicine treatment. Background Technology

[0002] Oral medicine is an important part of oral medicine, focusing on the diagnosis, treatment, and prevention of diseases of the teeth, gums, and related soft and hard tissues of the oral cavity. Its scope of practice is broad, mainly including dental pulp diseases, periodontal diseases, oral mucosal diseases, pediatric oral diseases, and preventive care.

[0003] Currently, oral healthcare professionals need to administer medications when treating patients with oral mucosal diseases. However, oral medications are usually in powder form, making administration difficult. Existing methods involve shaking the powder onto the affected area in the patient's mouth. Because the amount of powder shaken cannot be controlled, some powder fails to adhere to the affected area and falls into the patient's mouth, resulting in waste and discomfort. Therefore, existing oral medication administration methods are inconvenient. To address this, we provide a local drug delivery device for oral treatment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing oral medicine drug delivery methods, which easily lead to waste of medicine powder and patient discomfort, and to provide a local drug delivery device for oral medicine treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a local drug delivery device for oral cavity treatment, comprising: a drug delivery mechanism, the drug delivery mechanism including an inflation tube, a conical tube fixedly connected to one end of the inflation tube, a first leak plate sleeved inside the conical tube, the first leak plate being fixedly connected to the conical tube, a connecting tube provided at one end of the conical tube, a second leak plate sleeved inside the connecting tube, the second leak plate being fixedly connected to the connecting tube, a silicone sleeve sleeved on the outer surface of the connecting tube, the silicone sleeve being fixedly connected to the connecting tube, an auxiliary mechanism provided at one end of the inflation tube, the auxiliary mechanism including a first collar, a second collar provided on one side of the first collar, a locking rod sleeved inside the first collar, the locking rod being rotatably connected to the first collar, a moving block provided inside the first collar, the moving block being rotatably connected to the first collar, and the moving block being fixedly connected to the locking rod.

[0006] In a preferred embodiment, the first collar has an arc-shaped groove that matches the locking rod and the moving block, and the locking rod is fixedly connected to the second collar.

[0007] In a preferred embodiment, a push rod is sleeved inside the inflation tube, and a rubber plug is provided at one end of the push rod, with the rubber plug being fixedly connected to the push rod.

[0008] In a preferred embodiment, the rubber plug is fitted inside the inflation tube, and the rubber plug is slidably connected to the inflation tube.

[0009] In a preferred embodiment, one end of the push rod is provided with a push block, which is fixedly connected to the inflation tube.

[0010] In a preferred embodiment, the collar is fitted onto the outer surface of the tapered tube, and the collar is fixedly connected to the tapered tube.

[0011] In a preferred embodiment, the second collar is sleeved on the outer surface of the connecting pipe, and the second collar is fixedly connected to the connecting pipe.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This invention, through the provision of a drug delivery mechanism, allows for the administration of medication to the affected area within the patient's oral cavity. This ensures that the medication powder adheres to the affected area to the maximum extent, reducing powder waste and preventing excessive powder from falling into the oral cavity and causing discomfort. A silicone sleeve covers the affected area within the patient's oral cavity, blocking any flying powder and limiting its diffusion. A push rod and rubber stopper rapidly compress the air inside the inflation tube, causing a sudden increase in internal pressure. This propels the medication powder within the second perforating plate, ensuring it covers the affected area. An auxiliary mechanism is included to assist the drug delivery mechanism, preventing the powder within the second perforating plate from sliding into the inflation tube, thus guaranteeing an adequate amount of medication.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figures 1-4 As shown, this utility model provides a technical solution: a local drug delivery device for oral cavity treatment, comprising: a drug delivery mechanism 1, the drug delivery mechanism 1 including an inflation tube 11, one end of the inflation tube 11 being fixedly connected to a tapered tube 12, a first leak plate 13 being sleeved inside the tapered tube 12, the first leak plate 13 being fixedly connected to the tapered tube 12, one end of the tapered tube 12 being provided with a connecting tube 14, a second leak plate 15 being sleeved inside the connecting tube 14, the second leak plate 15 being fixedly connected to the connecting tube 14, and a silicone sleeve 16 being sleeved on the outer surface of the connecting tube 14. The air inflator 11 is fixedly connected to the connecting pipe 14. One end of the air inflator 11 is provided with an auxiliary mechanism 2. The auxiliary mechanism 2 includes a first collar 21 and a second collar 22 on one side of the first collar 21. A locking rod 23 is sleeved inside the first collar 21 and is rotatably connected to the first collar 21. A moving block 24 is provided inside the first collar 21 and is rotatably connected to the first collar 21. The moving block 24 is fixedly connected to the locking rod 23. An arc-shaped groove 25 is opened on the first collar 21 to fit the locking rod 23 and the moving block 24. The locking rod 23 is fixedly connected to the second collar 22.

[0026] In this embodiment, a second perforated plate 15 is provided, which is concave, so the medicine powder can be squeezed and filled into the interior of the second perforated plate 15. At the same time, a first perforated plate 13 is provided, which can be used in conjunction with the second perforated plate 15. The holes and grooves on the first perforated plate 13 and the second perforated plate 15 are misaligned under normal circumstances, so the medicine will not leak into the air tube 11 when it is filled into the second perforated plate 15. In addition, a silicone sleeve 16 is provided, which is soft and will not cause discomfort to the patient when covering the affected area in the patient's mouth. At the same time, it can restrict the medicine powder, thereby improving the utilization rate of the medicine powder. A push rod 17, a rubber stopper 18, and a push block 19 are provided, and the three can be used together to compress the air inside the air tube 11, thereby blowing the medicine powder.

[0027] Example 2

[0028] like Figures 1-4 As shown, a push rod 17 is sleeved inside the inflation tube 11. One end of the push rod 17 is provided with a rubber plug 18, which is fixedly connected to the push rod 17. The rubber plug 18 is sleeved inside the inflation tube 11 and is slidably connected to the inflation tube 11. One end of the push rod 17 is provided with a push block 19, which is fixedly connected to the inflation tube 11. A first collar 21 is sleeved on the outer surface of the tapered tube 12 and is fixedly connected to the tapered tube 12. A second collar 22 is sleeved on the outer surface of the connecting tube 14 and is fixedly connected to the connecting tube 14.

[0029] In this embodiment, an auxiliary mechanism 2 is provided to adjust the usage state of the second leak plate 15. When medication needs to be administered, the connecting tube 14 can be rotated, thereby aligning the second leak plate 15 with the slots on the first leak plate 13. The pressurized air inside the air tube 11 can then blow the powder inside the second leak plate 15. A locking rod 23 and a moving block 24 are provided, and the locking rod 23 and the moving block 24 can rotate within the arc-shaped groove 25 on the first collar 21, thereby assisting the rotation of the second leak plate 15.

[0030] Working principle:

[0031] like Figures 1-4As shown, in use, the push rod 17 and rubber plug 18 can be installed first. The rubber plug 18 is aligned with the inflation tube 11, and the push rod 17 is pushed by the push block 19, so that the rubber plug 18 slowly enters the inflation tube 11. Then, the therapeutic powder is filled into the second perforated plate 15, and the powder is squeezed to make it more complete. At this time, the auxiliary mechanism 2 can be used to rotate and adjust the second perforated plate 15. First, the second collar 22 drives the connecting tube 14 and the second perforated plate 15 to rotate. At the same time, the second collar 22 will drive the locking rod 23 and the moving block 24 to rotate in the arc groove 25 opened on the first collar 21 until the locking rod 23 and the moving block 24 can no longer rotate. Then the second perforated plate 15 is in the appropriate position. In this state, the holes and slots on the second perforator plate 15 and the first perforator plate 13 are aligned. Then, the second perforator plate 15 and the silicone sleeve 16 are slowly moved to the affected area in the patient's mouth, and the silicone sleeve 16 is placed over the affected area. Then, the air tube 11 is firmly grasped and the pusher block 19 is pushed forcefully. At this time, the pusher block 19 will drive the push rod 17 and the rubber stopper 18 to slide, and compress the air inside the air tube 11, so that the air pressure inside the air tube 11 and the conical tube 12 increases instantly. This blows the medicine powder in the second perforator plate 15 through the first perforator plate 13, so that the medicine powder flies and adheres to the affected area. The medicine powder that does not adhere will remain in the connecting tube 14, the second perforator plate 15 and the silicone sleeve 16. The remaining medicine powder can be transferred out of the mouth.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
