Description

Technical Field

[0001] The invention relates to the technical field of oral submucous fibrosis, in particular to a dressing placement device for oral submucous fibrosis. Background Art

[0002] Oral submucous fibrosis is a chronic oral mucosal disease characterized by epithelial atrophy, excessive accumulation and degeneration of collagen fibers in the mucosal lamina propria and submucosal layer, and changes in microvascular quality. The patient's clinical manifestations are usually limited mouth opening, pale, stiff and inelastic mucosa, burning sensation when eating, etc. Some patients present with dry mouth, decreased chewing, speech and taste functions. More seriously, oral submucous fibrosis is a precancerous lesion with a canceration rate as high as 7%-30%. Therefore, the prevention and treatment of oral submucous fibrosis has become a key issue in the research of oral mucosal diseases.

[0003] When facing the problem of oral submucous fibrosis, the current traditional method mostly uses drug delivery devices to apply therapeutic drugs to the patient's lesion area. However, although this method can achieve local delivery of drugs and improve the treatment effect to a certain extent, in actual operation, it also exposes some drawbacks that cannot be ignored.

[0004] First, when applying the medicine, the application device may not ensure uniform distribution of the medicine in the oral cavity, which may cause excessively high drug concentration in some areas and insufficient drug concentration in other areas, thus affecting the treatment effect.

[0005] Secondly, although automatic application treatment simplifies the medication process to a certain extent, it may still be difficult for some patients to use. For example, patients may need to master specific operating skills, or need multiple attempts to accurately apply the drug, which may affect patients' acceptance and usage experience.

[0006] Finally, when applying drugs, automatic application devices may cause drug waste due to improper operation or overdose, which not only increases treatment costs but may also have a negative impact on the environment.

[0013] The tops of both sides of the medicine storage box are fixedly connected with connection blocks, and one side of the connection block is fixedly connected with a fixing component.

[0014] The fixing assembly includes a clamping block 1 fixedly connected to the connecting block, one side of the clamping block 1 is rotatably connected to the clamping block 2, one side of the clamping block 1 and the clamping block 2 are both fixedly connected to a convex rod, and the opposite sides of the two convex rods are commonly fixedly connected to a spring 4.

[0016] Furthermore, as a preferred embodiment of the present invention, an external thread is provided on the top of the surface of the buffer rod, and a threaded connection is formed between the external thread and the threaded sleeve.

[0017] Furthermore, as a preferred embodiment of the present invention, the right side of the medicine storage box is connected with two injection tubes, the two injection tubes are used in conjunction with cavity one and cavity two respectively, and the inner cavity of the injection tube is provided with a rubber stopper.

[0018] Furthermore, as a preferred embodiment of the present invention, two slide grooves are provided on both sides of the inner cavity of the second spring tube, and both sides of the second sliding plate extend to the inner cavity of the second slide groove and are slidably connected to the second slide groove.

[0019] Furthermore, as a preferred embodiment of the present invention, the diameters of the liquid outlet hole 1 and the liquid outlet hole 2 are both larger than the diameter of the extrusion block.

[0020] Furthermore, as a preferred embodiment of the present invention, two rubber blocks are fixedly connected to opposite sides of the clamping block 1 and the clamping block 2.

[0021] In the present invention, a method for using a dressing placement device for oral submucous fibrosis comprises the following steps:

[0022] Step 1: inject the Danshen solution and the triamcinolone acetonide acetate solution into the inner cavities of the first and second cavities respectively, and tightly insert the rubber stopper into the inner cavity of the injection tube to effectively prevent accidental leakage of the liquid medicine; then, place the medicine storage box in the patient's oral cavity, ensure that the medical-grade silicone is tightly attached to the position of the oral submucosal fibrosis lesion, and place the clamping block 1 and the clamping block 2 on both sides of the patient's teeth respectively. Under the action of the elastic potential energy of the fourth spring, the clamping block 1 and the clamping block 2 rotate relative to each other to tightly fix the patient's teeth, thereby realizing the positioning of the medicine storage box;

[0023] Step 2: When the medical-grade silicone is located at the oral submucosal fibrosis lesion, the patient presses the fixing component with his teeth, and the fixing component drives the medicine storage box to move downward under the transmission of the connecting block. As the medicine storage box descends, it will gradually approach the extrusion block. At this time, the extrusion block will extend into the inner cavity of the second liquid hole and squeeze the sealing gasket. The rise of the sealing gasket will drive the linkage rod and the sliding plate 2 to move together. At the same time, the sliding plate 2 will squeeze the spring 3, so that the spring 3 is in a contracted state. As the sealing gasket 1 rises, the triamcinolone acetonide acetate solution in the inner cavity of the second cavity will flow out through the second liquid outlet hole, and the solution enters the medical-grade silicone under the guidance of the channel. The medicine storage box is evenly applied to the oral submucosal fibrosis lesion through the through hole. At the same time, the descent of the medicine storage box will drive the buffer plate to move downward and squeeze the spring 1 under the action of the threaded sleeve and the buffer rod. When the force of the teeth squeezing the fixed component disappears, the elastic potential energy of the spring 1 will be released, driving the buffer rod to move upward, so that the squeezing block is away from the sealing pad 1, and under the action of the elastic potential energy of the spring 3, the sliding plate 2, the connecting rod and the sealing pad 1 are driven to move, so that the sealing pad 1 blocks the liquid outlet hole 2 to prevent the medicine from being released too quickly. The patient can squeeze the fixed component according to actual needs to achieve the purpose of self-medication.

[0024] Step three: After the triamcinolone acetonide acetate solution in the inner cavity of cavity one is applied, the patient can apply greater pressure to the fixed component again. This time, the extrusion block will drive the sealing gasket one, the connecting rod and the sliding plate two to continue to move until the sliding plate two is located at the top of the inner cavity of the slide groove two. At this time, the continuous rise of the sealing gasket one will drive the spring tube two and the sealing gasket two to move together, thereby unsealing the sealing gasket two. As the spring tube two rises, it will drive the upper part of the sliding plate one and compress the spring two. At this time, the salvia miltiorrhiza solution in the inner cavity of cavity one will flow into the patient's lesion through the liquid outlet hole one, thereby realizing the autonomous application of the two kinds of liquid medicine and completing the comprehensive treatment process.

[0025] Beneficial effects. The technical solution of the present application has the following technical effects: the present invention has the advantages of reducing the difficulty of use and improving the uniformity of drug distribution. By adopting a double-layer cavity design, two different drugs can be stored separately, so that patients can control the extrusion force as needed during the treatment process to achieve step-by-step drug administration. After the first layer of drug liquid flows out, if further treatment or enhanced effect is needed, a greater force can be applied to make the second layer of drug liquid flow out. This step-by-step drug administration method not only improves the flexibility of treatment, but also can better adapt to the needs of different diseases; secondly, the patient only needs to place the device in the mouth and control the outflow of the drug liquid through a simple squeezing action, which reduces the difficulty of use and improves the patient's acceptance and usage experience; further, due to the use of a double-layer cavity and a controllable extrusion drug administration method, the drug liquid is avoided from being released too quickly, which not only helps to reduce drug waste and reduce treatment costs, but also ensures that the drug liquid is evenly distributed in the mouth, thereby improving the absorption rate and utilization rate of the drug.

[0056] Step three: After the triamcinolone acetonide acetate solution in the inner cavity of cavity 12 is applied, the patient can apply greater pressure to the fixing component 26 again. This time, the extrusion block 5 will drive the sealing gasket 21, the connecting rod 20 and the sliding plate 19 to continue to move until the sliding plate 19 is located at the top of the inner cavity of the slide groove 31.

A method for using a dressing placement device for oral submucous fibrosis, characterized in that: The method comprises the following steps: Step 1: inject Danshen solution and triamcinolone acetonide acetate solution into the inner cavities of cavity 1 (12) and cavity 2 (13) respectively, and insert the rubber stopper (30) tightly into the inner cavity of the injection tube (29) to effectively prevent accidental leakage of the drug solution; then, place the medicine storage box (11) in the patient's oral cavity, ensure that the medical-grade silicone (1) is tightly fitted to the position of the oral submucosal fibrosis lesion, and place the clamping block 1 (261) and the clamping block 2 (262) on both sides of the patient's teeth respectively. Under the action of the elastic potential energy of the spring 4 (264), the clamping block 1 (261) and the clamping block 2 (262) rotate relative to each other to tightly fix the patient's teeth, thereby achieving the positioning of the medicine storage box (11); Step 2: When the medical-grade silica gel (1) is located at the site of oral submucosal fibrosis, the patient presses the fixing component (26) with his teeth. The fixing component (26) drives the medicine storage box (11) to move downward under the transmission of the connecting block (25). As the medicine storage box (11) descends, it gradually approaches the extrusion block (5). At this time, the extrusion block (5) extends into the inner cavity of the second liquid inlet hole (24) and squeezes the sealing gasket one (21). The rise of the sealing gasket one (21) drives the linkage rod (20) and the sliding plate two (19) to move together. At the same time, the sliding plate two (19) squeezes the spring three (18), so that the spring three (18) is in a contracted state. As the sealing gasket one (21) rises, the triamcinolone acetate solution in the inner cavity of the second cavity (13) flows out through the second liquid outlet hole (24). The solution enters the medical-grade silica gel (1) under the guidance of the channel (4). The medicine storage box (11) is evenly applied to the surface of the graded silica gel (1) through the through hole (2) on the fibrotic lesion under the oral mucosa. At the same time, the descent of the medicine storage box (11) will drive the buffer plate (8) to move downward and squeeze the spring (7) under the action of the threaded sleeve (10) and the buffer rod (9). When the force of the teeth squeezing the fixed component (26) disappears, the elastic potential energy of the spring (7) will be released, driving the buffer rod (9) to move upward, so that the squeezing block (5) is away from the sealing gasket (21). Under the action of the elastic potential energy of the spring (18), the sliding plate (19), the linkage rod (20) and the sealing gasket (21) are driven to move, so that the sealing gasket (21) blocks the liquid outlet hole (24) to prevent the liquid medicine from being released too quickly. The patient can squeeze the fixed component (26) according to actual needs to achieve the purpose of self-medication. Step 3: After the triamcinolone acetonide acetate solution in the inner cavity of the cavity 1 (12) is applied, the patient can apply greater pressure to the fixing component (26) again. This time, the extrusion block (5) will drive the sealing gasket 1 (21), the connecting rod (20) and the sliding plate 2 (19) to continue to move until the sliding plate 2 (19) is located at the top of the inner cavity of the slide groove 2 (31). At this time, the continuous rise of the sealing gasket 1 (21) will drive the spring tube 2 (17) and the sealing gasket 2 (22) to move together, thereby unsealing the sealing gasket 2 (22). As the spring tube 2 (17) rises, it will drive the upper part of the sliding plate 1 (16) and compress the spring 2 (15). At this time, the salvia miltiorrhiza solution in the inner cavity of the cavity 1 (12) will flow into the patient's lesion through the liquid outlet hole 1 (23), thereby realizing the autonomous application of the two liquid medicines and completing the comprehensive treatment process.
