Description

Technical Field

[0001] The invention relates to an oral treatment instrument, in particular to a mucosal drug delivery device. Background Art

[0002] At present, local medication is often used in the treatment of oral mucosal diseases of the upper and lower lips and bilateral cheek mucosa. These drugs are usually ointments, pastes, gels or liquids, and are mostly used by gargling or rubbing. Since the salivary glands secrete about 1500ml of saliva every day, the drugs in the mouth are not only easily washed away by saliva, but also difficult to be fixed in the lesion area, which leads to a decrease in drug concentration and reduces the time the drug stays on the mucosa, thus affecting the efficacy.

[0003] Therefore, a mucosal drug delivery device is provided to solve the problems raised in the above background technology. Summary of the invention

[0004] The technical problem solved by the invention is how to improve the efficacy of drugs on the oral mucosa of the upper and lower lips and cheeks.

[0005] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a mucosal drug delivery device, comprising a first supporting part, a second supporting part and a fixing part, wherein the fixing part is fixed to the middle part between the first supporting part and the second supporting part, and the two sides of the fixing part form a first groove and a second groove with the first supporting part and the second supporting part, and the outer wall of the first supporting part has multiple grooves.

[0006] The beneficial effect of the present invention is that when the patient uses it, according to the position of the lesion area in the oral mucosa of the upper and lower lips or the upper lip of the cheek, the paste medicine or non-sticky medicine is first placed in the groove corresponding to the lesion area, and then the fixing part is tightly fitted with the upper and lower teeth, one end of the inner side of the first supporting part abuts against the outer sides of the upper and lower teeth, and one end of the outer side of the second supporting part abuts against the inner sides of the upper and lower teeth, so that the lower teeth are located in the second groove, and the upper teeth are located in the first groove at the same time, and then the patient's lips and cheek muscles are used to lightly close the lips to fix the medicine in the oral cavity, thereby avoiding displacement of the medicine and reducing the efficacy of the medicine.

[0007] Based on the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the plurality of grooves are arranged in sequence along the length direction of the first supporting portion.

[0009] The beneficial effect of adopting the above further solution is that the multiple grooves arranged in sequence can correspond to the lesion areas at different positions, thereby reducing the blind spots of treatment and improving the treatment efficiency.

[0010] Furthermore, the depth of the groove is 0.5 mmˉ2 mm.

[0011] The beneficial effect of adopting the above further solution is that it is convenient to place tablets or paste-like drugs of different thicknesses, thereby improving the applicability of the device.

[0012] Furthermore, the height of the first supporting portion gradually decreases from the middle to both ends.

[0013] The beneficial effect of adopting the above further solution is that the shape of the first supporting portion is similar to the shape of the dental arch of the human oral cavity, which facilitates the upper teeth to be completely located in the first groove 4, thereby improving the wearing comfort of the patient.

[0014] Furthermore, the height of the second supporting portion gradually decreases from the middle to both ends.

[0015] The beneficial effect of adopting the above further solution is that the shape of the second supporting part is similar to the shape of the dental arch of the human oral cavity, thereby improving the wearing comfort of the patient.

[0016] Furthermore, the width of the fixing portion is 5 mm-10 mm.

[0017] The beneficial effect of adopting the above further scheme is: the fixing part can fit tightly with the top of the upper and lower teeth, reducing the gap and preventing the applicator from shaking in the oral cavity, which will cause the medicine in the groove to not correspond to the lesion area and reduce the efficacy of the medicine.

[0018] Furthermore, the first supporting portion and the second supporting portion are both arc-shaped plates.

[0019] The beneficial effect of adopting the above further solution is that the arc-shaped first supporting portion and the second supporting portion are more ergonomically designed, thereby improving the wearing comfort of the patient.

[0020] Furthermore, the thickness of the first supporting portion, the second supporting portion and the fixing portion are all 2 mm-4 mm.

[0021] The beneficial effect of adopting the above further solution is that the thin design makes it easier for patients to adapt to the drug delivery device more quickly, thereby improving the quality of life of patients.

[0022] Furthermore, the first supporting portion, the second supporting portion and the fixing portion are integrally formed. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] like Figure 1-Figure 4 As shown, this embodiment provides a mucosal drug delivery device, including a first supporting portion 1, a second supporting portion 2 and a fixing portion 3, wherein the fixing portion 3 is fixed to the middle portion between the first supporting portion 1 and the second supporting portion 2, and the two sides of the fixing portion 3 form a first groove 4 and a second groove 5 with the first supporting portion 1 and the second supporting portion 2, and the outer wall of the first supporting portion 1 has a plurality of grooves 101.

[0031] When the patient uses it, according to the position of the lesion area in the oral mucosa of the upper and lower lips and cheeks, the paste medicine or non-sticky medicine is first placed in the groove 101 corresponding to the lesion area, and then the fixing part 3 is tightly fitted with the upper and lower teeth, one end of the inner side of the first supporting part 1 is in contact with the outer side of the upper and lower teeth, and one end of the outer side of the second supporting part 2 is in contact with the inner side of the upper and lower teeth, so that the lower teeth are located in the second groove 5, and the upper teeth are located in the first groove 4 at the same time, and then the patient's lips and cheek muscles are used to lightly close the lips to fix the medicine in the oral cavity to avoid displacement of the medicine and reduce the efficacy of the medicine.

[0032] Specifically, when the applicator is placed in the patient's mouth, the fixing part 3 is in close contact with the top of the lower dentition, the other end of the inner side of the first supporting part 1 abuts against the outer side of the upper dentition, and the other end of the outer side of the second supporting part 2 abuts against the inner side of the upper dentition.

[0033] Among them, when the drug is absorbed, the device can be removed and the patient only needs to wear it for a short time, avoiding affecting the patient's daily life and improving the patient's quality of life.

[0034] Specifically, Figure 1 As shown, in this embodiment, adjacent grooves 101 have different shapes and sizes, and the shape of the groove 101 can be a circular, elliptical or polygonal groove, so as to place medicines of different shapes and corresponding to lesion areas in different positions.

[0035] When the medicine is sticky, the medicine can be placed on the affected area first, and then the applicator is placed in the oral cavity to allow the medicine to be stuck in the groove 101 .

[0036] On the basis of the above solution, a plurality of the grooves 101 are arranged in sequence along the length direction of the first supporting portion 1 .

[0037] The multiple grooves 101 arranged in sequence can correspond to the lesion areas at different positions, thereby reducing the blind spots of treatment and improving the treatment efficiency.

[0038] Specifically, the plurality of grooves 101 may be arranged at intervals.

[0039] Based on the above solution, the depth of the groove 101 is 0.5 mmˉ2 mm.

[0050] The height of the second support portion 2 is less than or equal to the height of the first support portion 1 .

[0051] Based on the above solution, the width of the fixing portion 3 is 5 mm - 10 mm.

[0052] The fixing part 3 can be tightly fitted with the top of the lower dentition to reduce the gap and prevent the applicator from shaking in the oral cavity, which will cause the medicine in the groove 101 to not correspond to the lesion area and reduce the efficacy of the medicine.

[0053] Specifically, the fixing portion 3 is an arc-shaped flat plate.

[0054] Alternatively, when the heights of the first supporting portion 1 and the second supporting portion 2 gradually decrease from the middle to the two ends, the width of the fixing portion 3 also gradually decreases from the middle to the two ends.

[0055] On the basis of the above solution, the first supporting portion 1 and the second supporting portion 2 are both arc-shaped plates.

[0056] The arc-shaped first supporting portion 1 and the second supporting portion 2 are more ergonomically designed and improve the wearing comfort of the patient.

[0057] Specifically, the first supporting portion 1 and the second supporting portion 2 are both similar in shape to a human dental arch.

[0059] On the basis of the above solution, the thickness of the first supporting part 1, the second supporting part 2 and the fixing part 3 are all 2 mm-4 mm.

[0060] The thin design makes it easier for patients to adapt to the applicator and improves their quality of life.

[0061] Specifically, the thickness of the second supporting portion 2 and the fixing portion 3 can also be set to 0.1 mm-1 mm.

[0062] On the basis of the above solution, the first supporting portion 1, the second supporting portion 2 and the fixing portion 3 are integrally formed.

[0063] Specifically, two sides of the fixing portion 3 may be bonded to the first supporting portion 1 and the second supporting portion 2 by adhesive.

[0064] Among them, the thickness of the adhesive is 0.1mm.

[0065] In this embodiment, when using, first, according to the position of the lesion area in the lower lip oral mucosa, a paste-like medicine or a non-viscous medicine is placed in the groove 101 corresponding to the lesion area;

[0066] Secondly, the fixing part 3 is tightly fitted with the top of the lower dentition, one end of the inner side of the first supporting part 1 is in contact with the outer side of the lower dentition, one end of the outer side of the second supporting part 2 is in contact with the inner side of the lower dentition, the other end of the inner side of the first supporting part 1 is in contact with the outer side of the upper dentition, and the other end of the outer side of the second supporting part 2 is in contact with the inner side of the upper dentition, so that the upper dentition and the lower dentition of the patient are respectively located in the first groove 4 and the second groove 5;
