Technical Field
[0001] This utility model belongs to the field of medical tool technology, specifically relating to a drug delivery device for the treatment of periodontitis. Background Technology
[0002] Periodontitis, also known as destructive periodontitis, is a chronic inflammatory disease mainly caused by bacteria in dental plaque damaging periodontal tissues. This damage affects the periodontal supporting tissues (including the gums, periodontal ligament, alveolar bone, and cementum). The main symptoms of periodontitis include red and swollen gums, easy bleeding, and periodontal pocket formation. It may also be accompanied by loose teeth, tooth displacement, and even tooth loss.
[0003] Currently, for some symptoms of periodontitis such as swollen and bleeding gums, medical staff can treat them by spraying medication onto the affected area. The spray can generally eliminate gum inflammation, maintain oral hygiene, and maintain the oral flora environment. However, when medical staff spray medication onto patients' teeth or mouths, they usually spray directly onto the affected area. Due to the fluidity of the medication, it cannot stay on the affected area for a long time, and the affected area cannot fully contact the medication, affecting the therapeutic effect. Therefore, there is a need to propose a periodontitis treatment drug delivery device to solve the above problems. Utility Model Content

[0022] Example
[0023] Please see Figures 1-5This utility model provides the following technical solution: a periodontitis treatment drug release device, including a reservoir 1 for storing the drug solution to be sprayed. A liquid guide tube 13 is connected through the top surface of the reservoir 1, possessing a certain elasticity and preventing easy bending and sagging. A shielding sleeve 2 is fitted onto the outer side of one end of the liquid guide tube 13. The shielding sleeve 2 includes a transparent clip 21, a first elastic tube 22, and a second elastic tube 23. The transparent clip 21 is arc-shaped, conforming to the patient's gums, and its transparent material facilitates observation of the drug spraying process by medical personnel. A hole 211 is provided on one side wall of the transparent clamp 21. One end of the liquid guide tube 13 is inserted into the inner side of the hole 211. A collar 212 is fixed on one side wall of the transparent clamp 21, located outside the hole 211. A third limiting ring 213 is fixed to the inner side of the collar 212. A retaining ring 131 is fixed to the outer wall of one end of the liquid guide tube 13, located inside the collar 212. The third limiting ring 213 is located on one side of the retaining ring 131, which can improve the insertion stability of the liquid guide tube 13. (See attached diagram.) Figure 1 Appendix Figure 2 and attached Figure 3 The top surface of the transparent splint 21 is fixed with a first elastic tube 22, which is hollow and elastic, and can conform to the patient's gums. The side walls of the transparent splint 21 are fixed with a second elastic tube 23. The two end side walls of the transparent splint 21 are U-shaped, and the second elastic tube 23 is similar. The transparent splint 21 is made of elastic material. In this solution, when spraying medication for patients with periodontitis, the transparent splint 21 is clipped onto the outside of the patient's gums, so that the elastic tubes around the transparent splint 21 can squeeze and conform to the patient's gums, thereby achieving the covering and shielding of the affected area. Then, the medical staff inserts one end of the drainage tube 13 into the transparent splint 21, and then squeezes the liquid reservoir 1 to spray the medication, so that the medication can stay on the inside of the transparent splint 21, thereby allowing the patient's affected area to fully contact the medication and improve the treatment effect.
[0024] Reference Figure 2 and Figure 5 As shown, specifically, the liquid storage cylinder 1 includes a squeezing cylinder 11 and an end cap 12. The top surface of the squeezing cylinder 11 is provided with a plug-in ring 111, and the bottom surface of the end cap 12 is provided with a slot 121. The plug-in ring 111 is inserted into the inner side of the slot 121, which is convenient for insertion and removal, and facilitates the replacement or replenishment of the liquid. One end of the liquid guide tube 13 passes through the end cap 12, and the other end of the liquid guide tube 13 is located at the bottom inner side of the liquid storage cylinder 1, which can guide the liquid. The liquid storage cylinder 1 is made of elastic material. A first limiting ring 112 is fixed on the side wall of the plug-in ring 111, and a first limiting groove 122 is provided on the inner wall of the slot 121. The first limiting ring 112 is located inside the first limiting groove 122. With the elastic liquid storage cylinder 1, this solution facilitates the replacement of the liquid and allows the liquid to be sprayed through the liquid guide tube 13 by squeezing, making the operation convenient.
[0025] Reference Figure 2 and Figure 3As shown, specifically, a collection cover 3 is sleeved on the outside of the liquid guide tube 13. A fitting gasket 31 is fixed to the edge of the collection cover 3 to fit the skin on the outside of the patient's mouth. A through hole 32 is provided in the middle of the side wall of the collection cover 3, through which the liquid guide tube 13 passes. The collection cover 3 is made of elastic material. A positioning sleeve 132 is fixed to the outer wall of one end of the liquid guide tube 13. The positioning sleeve 132 is inserted into the inside of the through hole 32. A second limiting ring 133 is fixed on the outer wall of the positioning sleeve 132. A second limiting groove 33 is provided on the inner wall of the through hole 32. The second limiting ring 133 is located inside the second limiting groove 33. The second limiting ring 133 is made of elastic material. Through the above structure, the collection cover 3 can be stably sleeved on the outside of the liquid guide tube 13. When spraying medicine into the patient's oral cavity or the entire gum, the collection cover 3 can be placed on the outside of the patient's mouth to prevent the liquid flowing from the patient's mouth from spilling and wetting the clothes. It is easy to clean and highly practical.
[0026] The working principle and usage process of this utility model are as follows: When applying medication to the affected area of a patient with periodontitis, medical staff select a suitable length of shielding sleeve 2 according to the specific condition of the patient's gums and clip it onto the patient's gums. This allows the transparent splint 21 to fit against the patient's gums through the hollow elastic tubes around its periphery, thus covering and shielding the affected area. Subsequently, the medical staff insert one end of the liquid guide tube 13 into the upper insertion hole 211 of the transparent splint 21. By squeezing the liquid reservoir 1 containing the medication, the medication is sprayed onto the affected area through the liquid guide tube 13. At the same time, the elastic tubes ensure that the affected area fully contacts the medication, improving the treatment effect.
[0027] When it is necessary to spray medication on the patient's entire gums or oral cavity, medical staff can attach the collection cover 3 to the outside of the drainage tube 13 and fix it in place by inserting the positioning sleeve 132 into the middle of the collection cover 3. Then, the collection cover 3 is placed against the outside of the patient's mouth. At this time, the drainage tube 13 extends into the inside of the patient's oral cavity to spray the medication. The liquid flowing out of the patient's oral cavity can be collected through the collection cover 3, which is convenient for collection.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
