Description

Technical Field

[0001] This invention relates to the field of oral care equipment, specifically a portable oral protective drug delivery device and intervention method for reducing the incidence of oral mucositis caused by chemotherapy drugs. Background Technology

[0002] Currently, clinical prevention and intervention for chemotherapy-induced oral mucositis mostly employ traditional manual oral care methods. This involves caregivers using tools such as tongue depressors, cotton swabs, and irrigation tubes to perform oral examinations, mucosal cleaning, and medication application. This traditional approach has many inherent technical limitations, severely restricting the effectiveness of oral health interventions. Firstly, manual tongue depressors are unstable and the pressing angle is uncontrollable. The tongue is prone to shaking, obscuring deep areas of the oral cavity and creating blind spots in areas such as the buccal mucosa, floor of the mouth, soft palate, and pharyngeal walls. This makes it impossible to achieve comprehensive mucosal cleaning and medication protection, and the long-term inadequate protection of local mucosa is the core cause of localized mucositis. Secondly, routine oral care lacks dedicated lighting aids, resulting in poor visibility in the deep oral cavity. Caregivers can only observe the superficial mucosal condition with the naked eye, making it difficult to accurately identify early microscopic mucosal damage. This hinders early detection and intervention, easily leading to minor mucosal damage progressing to severe erosion and ulceration. Thirdly, traditional methods lack dedicated adaptive oral opening devices, resulting in poor stability of manual mouth opening and difficulty in maintaining a consistent range of mouth opening and closing. This not only leads to low precision in medication administration and cleaning, causing uneven application and incomplete rinsing, but also easily causes secondary damage such as pulling on the corners of the mouth and puncturing the mucosa due to repeated mouth opening and blind operation, exacerbating the patient's oral discomfort symptoms.

[0003] Existing oral care assistive devices are mostly fixed, simple mouth-opening structures with limited functionality. They cannot adaptively adjust and fix themselves according to different patients' facial contours and oral cavity sizes, resulting in poor adaptability and low versatility. Furthermore, they generally lack integrated structures for tongue depressor positioning, multi-angle lighting, and tool fixation, failing to simultaneously achieve integrated intervention functions such as oral cavity opening, visual field exposure, precise drug administration, and safe ventilation. Moreover, existing devices are mostly one-piece structures, making disassembly, cleaning, and disinfection difficult. Secretions and drug residues easily remain in the gaps, making it difficult to meet the high standards of aseptic operation required for chemotherapy oral care and increasing the risk of cross-infection in the oral cavity. Summary of the Invention

[0004] The technical problem to be solved by this invention is to overcome the above-mentioned technical defects.

[0005] To address the aforementioned problems, the technical solution of this invention is: a portable oral protection drug delivery device and intervention method for reducing the incidence of oral mucositis caused by chemotherapy drugs, comprising a fixation frame, a mouth opener, and a lighting device; The mouth opener has an arc-shaped structure and is divided into two parts. The upper and lower parts are connected by a rotatable connection. The upper part of the mouth opener has several evenly distributed fixing holes. The two sides of the mouth opener are respectively provided with limiting grooves. The two limiting grooves are arranged opposite each other and are used to fix external nursing equipment. The lower two sides of the mouth opener are fixedly connected with fixing plates. The front side of the two fixing plates is provided with opening grooves. A tongue depressor is rotatably connected between the two opening grooves. The fixing frame is located at the bottom of the mouth opener and includes two retractable support columns. The two support columns are fixedly connected to the lower sides of the mouth opener, and a fixing strip is fixedly connected between the two support columns. The fixing strip has several evenly distributed grooves for fixing the nursing tool.

[0006] Furthermore, the tongue depressor includes two support plates that are rotatably connected to the opening groove, and a tongue depressor plate is fixedly connected between the two support plates.

[0007] Furthermore, the tongue depressor plate is provided with a number of evenly distributed air holes.

[0008] Furthermore, a handle is inserted into the rear side of the mouth support.

[0009] Furthermore, the lighting device includes a connecting rod rotatably connected to the mouthpiece, on which a controllable lighting lamp is provided.

[0010] An intervention method for a portable oral protective drug delivery device to reduce the incidence of oral mucositis caused by chemotherapy drugs. S1. Equipment pretreatment: The portable oral protective drug delivery device is disassembled and disinfected as a whole, with a focus on the detachable tongue depressor, mouth support, lighting device and external nursing accessories. After disinfection, the device is reassembled and the telescopic, rotation and lighting functions of the device are checked to see if they are normal. S2. Patient positioning and equipment fixation: Assist the patient to assume a semi-recumbent or sitting position with the head slightly tilted back. Place the equipment fixation frame against the patient's chin and adjust the height of the two retractable pillars to match the patient's oral opening range and facial size to complete the overall positioning and fixation of the equipment. S3. Oral opening and visual aid: The patient's oral cavity is opened appropriately by rotating the arc-shaped mouth opener through the connecting structure. According to nursing needs, the external nebulized drug delivery and oral irrigation nursing equipment is fixed by the limiting grooves set on both sides of the mouth opener. At the same time, the angle of the connecting rod of the lighting device is adjusted to turn on the controllable lighting light, clearly exposing the patient's oral mucosa, tongue and lesion areas between teeth. S4. Tongue depressor positioning and oral intervention: Rotate the support plate to move the detachable tongue depressor to fit the patient's tongue surface, fix the tongue position, expose the deep oral mucosa, and ensure oral ventilation through the ventilation holes of the tongue depressor. Then, rely on the groove on the fixing strip to fix the drug delivery and cleaning care tools, and perform drug application, atomized drug delivery, and wound cleaning intervention on the patient's oral mucosa. S5. Postoperative care and equipment maintenance: After a single oral protective drug administration intervention, turn off the lighting device, slowly close the mouth support, remove the equipment and disassemble detachable parts such as the tongue depressor, thoroughly clean the gaps in the equipment and residual secretions on the surface of the components, disinfect and sterilize again, and store for later use after drying.

[0011] The advantages of this invention compared to existing technologies are: This invention features an adjustable arc-shaped mouth opener and a detachable tongue depressor. The mouth opener adapts to the patient's oral cavity size, while the tongue depressor, with its ventilation holes, gently secures the tongue. This allows for thorough exposure of mucosal areas traditionally missed, such as the buccal mucosa, floor of the mouth, soft palate, and deep pharynx. Simultaneously, a multi-angle adjustable lighting device enables visualized operation across the entire oral cavity, allowing for precise mucosal cleaning, medication application, and nebulized drug delivery. This ensures even coverage of the entire oral mucosa with protective medication, effectively repairing mucosal epithelial cells damaged by chemotherapy drugs and avoiding congestion, erosion, and ulceration caused by insufficient local drug coverage or inadequate cleaning. Clinical trials have demonstrated a significant reduction in the incidence of oral mucositis in chemotherapy patients and effectively prevent severe mucositis, thus fundamentally improving the effectiveness of oral protection during chemotherapy.

[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0016] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0017] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figures 1 to 2 As shown, a portable oral protective drug delivery device and intervention method for reducing the incidence of oral mucositis caused by chemotherapy drugs are disclosed. The intervention is carried out on cancer patients who have not developed oral mucositis. During the intervention, the patient is assisted in adjusting their position. The semi-recumbent position is preferred according to the patient's physical condition. Patients with weak physical condition are adopted in a sitting position with their head slightly tilted back to relax the facial and neck muscles and fully expose the oral and maxillofacial area to avoid oral traction discomfort or obstruction of the operation field due to improper position.

[0019] The device's mounting bracket is placed against the patient's lower jaw, using the jawline as a reference. The height of the retractable support pillars is adjusted simultaneously on both sides. The length of the pillars is then fine-tuned based on the patient's mouth opening range and facial width to adapt to different patients' facial structures. After adjustment, the height is fixed using the pillar's self-locking mechanism, ensuring the mouth opener is aligned with the center of the patient's mouth. The device is stably fitted to the face without shifting or causing localized pressure. This completes the overall positioning and fixation of the device, ensuring stability for subsequent mouth opening, medication administration, and nursing procedures, and preventing damage to the oral mucosa from device movement during operation.

[0020] After the device is fixed in place, slowly and evenly open and close the arc-shaped mouth opener using the rotating connection structure at the top and bottom of the mouth opener. The opening should be moderately adjusted according to the patient's oral tolerance, ensuring no significant pulling pain or compression of the oral mucosa. Avoid excessive opening that could damage the lips or corners of the mouth. For patients requiring nebulized medication or oral irrigation, insert the external nebulizer nozzle, oral irrigation head, or other nursing equipment into the opposing limiting grooves on both sides of the mouth opener. The limiting grooves will lock the device in place, preventing movement and ensuring accurate medication and irrigation.

[0021] Adjust the lighting device according to the depth of the patient's oral cavity and the location of the lesions. Rotate the linkage to adjust the angle and height of the controllable light, focusing the light on key areas such as the patient's oral mucosa, tongue, gaps between teeth, and lateral pharyngeal walls. This clearly exposes early lesions such as minor congestion, leukoplakia, and minor damage to the mucosa, solving the problems of dim vision and incomplete exposure of deep mucosa in traditional oral care. This allows nurses to accurately observe the condition of the mucosa and carry out targeted care, while avoiding secondary damage to the mucosa caused by blind operation.

[0022] After the field of vision is adjusted, initiate the tongue depressor positioning procedure. Rotate the support plate inside the opening groove to slowly press the tongue depressor against the patient's tongue surface, gently pressing down to fix the tongue in position. This fully exposes the deep mucosal areas such as the buccal mucosa, floor of the mouth, and soft palate, completely eliminating blind spots caused by tongue obstruction. The evenly distributed ventilation holes on the surface of the tongue depressor continuously ensure unobstructed airflow in the patient's oral cavity, preventing breathlessness and breathing difficulties during tongue depressor operation, thus improving operational safety and patient tolerance.

[0023] In conjunction with the chemotherapy-induced oral mucositis prevention and intervention program, multi-dimensional oral health care was implemented: Nursing tools such as medication brushes, sterile cotton swabs, irrigation catheters, and nebulizer heads were secured using evenly distributed grooves on a fixation strip, ensuring organized fixation and easy access. For routine preventative interventions in chemotherapy patients, sterile saline solution was used to rinse and clean the entire oral mucosa, removing food debris, secretions, and medication residues. Recombinant human epidermal growth factor gel was applied to areas with thin, easily eroded mucosa to promote mucosal repair. For high-risk patients with oral mucositis, an external nebulizer was used for oral nebulization, delivering anti-inflammatory and mucosal-protective medications evenly to the entire oral mucosa, forming a protective film and reducing the probability of mucosal damage. The entire intervention process was fully visualized, precise, and without blind spots, comprehensively covering all oral mucosal areas.

[0024] After a single oral intervention procedure, first turn off the controllable lighting, then slowly rotate the mouth opener in the opposite direction to gently release the mouth from its open position, avoiding rapid retraction of the oral mucosa. Next, carefully remove the entire device, disassembling the tongue depressor, lighting rod, external care accessories, and other detachable components. Clean each component and crevices thoroughly to remove any remaining oral secretions, medication residue, and food debris, paying particular attention to hidden areas such as the tongue depressor's vent holes, positioning grooves, and fixing recesses to ensure no residue remains. After cleaning, disinfect the entire device again with medical disinfectant, rinse with sterile saline solution, air dry, and store in a sterile storage box, protected from light and dust, for future use.

[0025] Intervention cycle setup: All patients received standardized oral hygiene and medication administration twice daily, once in the morning on an empty stomach and once at bedtime, until the end of the chemotherapy cycle. The control group received conventional oral hygiene care, including traditional open-mouth care, tongue depressor application, and manual medication administration, with the same frequency as the observation group.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
