Description

Technical Field

[0001] This utility model relates to the field of medical and nursing device technology, specifically to a mouthwash device for relieving radiation-induced oral mucositis in patients. Background Technology

[0002] Radiation-induced oral mucositis is one of the most common and distressing complications in head and neck cancer patients undergoing radiotherapy or combined chemoradiotherapy. Its pathological mechanism involves radiation damage to the basal cells of the oral mucosa, leading to inflammation, atrophy, ulceration, and even necrosis of the mucosal tissue. Clinically, it manifests as oral pain, dysphagia, altered taste, dry mouth, and secondary infections. In severe cases, it may force the interruption of radiotherapy, affecting tumor control and significantly reducing the patient's quality of life and nutritional status.

[0003] Currently, routine oral care for radiation-induced oral mucositis mainly involves rinsing with saline solution, sodium bicarbonate solution, or special mouthwash containing antibacterial, analgesic, and repair-promoting ingredients. However, traditional rinsing methods have significant limitations: patients often have difficulty completing effective rinsing movements due to oral pain, limited mouth opening, or fragile mucosa, resulting in uneven distribution and incomplete coverage of the medication; the mouthwash directly impacts the wound in the form of a liquid jet, causing mechanical irritation and pain to the damaged mucosa; for bedridden, weak, or unconscious patients, there is a risk of aspiration; in addition, the mixture of saliva and medication produced after rinsing needs to be spat out by the patient, which is inconvenient and easily contaminates the environment for some patients with limited mobility or excessive oral secretions.

[0004] Therefore, there is an urgent clinical need for an oral medication and cleaning device that can achieve gentle, uniform, controllable, and easy-to-operate administration to improve the comfort, safety, and effectiveness of care for radiation-induced oral mucositis. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a mouthwash device for relieving radiation-induced oral mucositis in patients, comprising a reservoir tube, wherein an infusion tubing is installed at the tail end of the reservoir tube for delivering a medium into the reservoir tube.

[0006] The front end of the liquid storage tube is equipped with a retractable atomizing component, which is used to atomize the medium inside the tube.

[0007] A protective cover assembly is installed on the side of the liquid storage tube, near the atomizing component, to prevent the atomizing medium from splashing out.

[0008] Preferably, the liquid storage tube has two interconnected channels, namely channel one and channel two. The inner diameter of channel one is smaller than that of channel two. One end of channel one passes through the front end of the liquid storage tube, and one end of channel two passes through the tail end of the liquid storage tube.

[0009] Preferably, one end of the infusion tubing is fixed with a first connector, which is threaded to the tail end of the storage tube and communicates with channel two.

[0010] Preferably, the atomizing component includes a connecting tube that is movably fitted inside the first channel, and a sealing ring is fixed at the tail end of the connecting tube, with the outer side of the sealing ring fitting against the inner side of the second channel.

[0011] Preferably, two slide rail rings are fixed on the side of the connecting pipe away from both ends, and a movable block is movably connected to the side of the slide rail ring. The bottom of the movable block is provided with a slide rail groove along its width direction, and the slide rail groove is slidably connected to the side of the slide rail ring.

[0012] Preferably, a limiting groove is provided on the side of the liquid storage tube along the length of the channel, and the moving block is slidably connected in the limiting groove.

[0013] Preferably, the side of the liquid storage tube is embedded with a ball bearing, and the side of the ball bearing and the side of the connecting tube are provided with meshing toothed patterns between the two slide rail rings.

[0014] Preferably, a spray pipe is fixed to the front end of the connecting pipe, and multiple atomizing nozzles are arranged circumferentially on the side of the spray pipe.

[0015] Preferably, an adjustment mechanism is installed inside the spray pipe. The adjustment mechanism includes three strip plates arranged along the length of the spray pipe. One end of each of the three strip plates is fixed with a connecting plate perpendicular to it. A second connector is fixed to the front end of the three connecting plates. One end of the second connector is fixed with a knob, and the knob passes through the front end of the spray pipe.

[0016] Preferably, the protective cover assembly includes a sealing cover that is movably fitted onto the front end of the liquid storage tube, a water collection interface is provided inside the sealing cover, a sealing ring is provided at one end of the sealing cover along its edge path, and a positioning button is threadedly connected to the side of the other end of the sealing cover.

[0017] The protective cover assembly also includes multiple positioning holes circumferentially distributed at the front end of the liquid storage tube, with the front end of the positioning button inserted into the corresponding positioning hole.

[0018] Compared with the prior art, this utility model provides a mouthwash device to alleviate radiation-induced oral mucositis in patients, and has the following beneficial effects: 1. This mouthwash device, designed to alleviate radiation-induced oral mucositis, uses an atomizing nozzle to break liquid mouthwash into fine droplets for spraying, replacing traditional liquid jet rinsing. This provides a gentle and even coverage of the oral mucosal lesions, significantly reducing physical irritation and pain to the damaged mucosa, and improving patient tolerance and comfort. Simultaneously, by rotating a knob to drive the internal adjustment mechanism, the atomization flow rate and the number of nozzles in use can be steplessly adjusted, flexibly adapting to different severity levels of oral mucositis, different treatment stages, and the need for targeted care of specific areas, thus achieving personalized and precise care.

[0019] 2. This mouthwash device, which alleviates radiation-induced oral mucositis in patients, allows for easy adjustment of the spray angle after the device is inserted into the oral cavity by rotating the connecting tube and the front spray tube through a ball bearing. This ensures that the atomized medication can effectively cover all oral anatomical areas such as the tongue, cheek, palate, and pharynx, overcoming the shortcomings of traditional mouthwashes that are difficult to evenly cover dead corners. Furthermore, the telescopic design of the connecting tube makes it easy to store and prevents the risk of contamination from prolonged exposure during non-use periods.

[0020] 3. This mouthwash device, designed to alleviate radiation-induced oral mucositis in patients, features a protective cover assembly with a flexible sealing ring. During use, it conforms to the area around the lips, creating a relatively enclosed space. The atomized droplets and patient saliva are effectively collected within the cover and promptly removed via a negative pressure suction device connected to the water collection interface. This effectively avoids the inconvenience of patients frequently getting up to spit out mouthwash, making it particularly suitable for bedridden or frail patients. It significantly reduces the risk of aspiration, maintains the cleanliness of the patient's face and surrounding environment, and reduces the workload of nursing care. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] Please see Figure 1 - Figure 6 As shown, the mouthwash device for relieving radiation-induced oral mucositis proposed in this embodiment includes a cylindrical liquid storage tube 1 made of metal. Inside the liquid storage tube 1, there are two interconnected channels along its length, namely channel 11 at the front end and channel 12 at the rear end. The inner diameter of the channels is smooth. The front end of channel 11 passes through the front end of the liquid storage tube 1, and the rear end of channel 12 passes through the rear end of the liquid storage tube 1.

[0025] Meanwhile, the inner diameter of channel 11 is smaller than the inner diameter of channel 212.

[0026] A flexible silicone infusion tube 2 is installed at the end of the reservoir tube 1. A first connector 21 is fixed to the end of this tube, threaded onto the end of the reservoir tube 1, allowing communication between the inside of the infusion tube 2 and the inside of the reservoir tube 1. By connecting the other end of the infusion tube 2 to a device for supplying a medium (i.e., liquid mouthwash for patients with radiation-induced oral mucositis), the medium is introduced into channel 12 within the reservoir tube 1 via the infusion tube 2. A limiting groove 13 is opened along the axial direction on the side wall of the liquid storage tube 1, and a freely rotating ball bearing 14 is also embedded in its wall surface.

[0027] The front end of the liquid storage tube 1 is equipped with a retractable atomizing component 3. The component includes a metal connecting tube 31, and a sealing ring 32 is fixed at the interface at its tail end. The connecting tube 31 is inserted into the first channel 11, and the sealing ring 32 at its tail end is located in the second channel 12 and slides and seals against the inner wall, ensuring that the medium in the second channel 12 can only enter the connecting tube 31.

[0028] Two slide rail rings 311 are fixed on the body of the connecting pipe 31. At the same time, a moving block 33 is movably connected to the side of the connecting pipe 31. Two slide rail grooves 331 are opened at the bottom of the moving block 33 along its width direction. The moving block 33 slides across and slides on the two slide rail rings 311 through the slide rail grooves 331, so that the moving block 33 can drive the connecting pipe 31 to move back and forth along the path of channel 11, but does not restrict the rotation of the connecting pipe 31.

[0029] Meanwhile, a limiting groove 13 matching the length of the liquid storage tube 1 is provided on the side of the liquid storage tube 1 along the length direction of the channel 11. The width of the moving block 33 matches the width of the groove, ensuring that the moving block 33 can slide smoothly back and forth in the groove and control the extension and retraction of the connecting tube 31.

[0030] In addition, the tube surface between the two slide rail rings 311 is machined with toothed patterns 312, and the side of the ball bearing 14 is also provided with toothed patterns 312. The toothed patterns 312 of the two mesh with each other. By rotating the ball bearing 14, the meshing force of the toothed patterns 312 is used to drive the connecting tube 31 to rotate, thereby controlling the rotation of the front functional component (the spray tube 34 described below) and adjusting its angle.

[0031] It should be further explained that when the connecting tube 31 extends outward from the liquid storage tube 1, the ball 14 crosses the nearest slide rail ring 311 and enters between the two slide rail rings 311, making the ball 14 engage with the toothed pattern 312 on the side of the connecting tube 31. When the connecting tube 31 is retracted into the liquid storage tube 1, the ball 14 crosses the corresponding slide rail ring 311, making the toothed pattern 312 separate.

[0032] A spray pipe 34 is fixed to the front end of the connecting pipe 31. Multiple atomizing nozzles 341 are circumferentially opened on the pipe wall. An adjustment mechanism 35 is installed inside the spray pipe 34. The mechanism consists of three strip plates 351 arranged axially. The strip plates 351 are attached to the inner wall of the spray pipe 34. Each strip plate 351 has a connecting plate 352 fixed at the same end, perpendicular to it. The front ends of the three connecting plates 352 are fixed to the side of the same second connecting head 353. The front end of the second connecting head 353 penetrates the front wall of the spray pipe 34 and is fixed with a knob 354. When the knob 354 is rotated, it can drive the three strip plates 351 to rotate synchronously through the second connecting head 353 and the connecting plate 352, thereby changing their relative position with the atomizing nozzles 341 and realizing the adjustment of the atomization flow rate and the number of nozzles in operation.

[0033] A protective cover assembly 4 is installed on the side of the reservoir tube 1, near the atomizing assembly 3. The assembly includes a funnel-shaped sealing cover 41. The inner diameter of the small end interface of the cover matches the diameter of the side of the reservoir tube 1. By fitting the cover onto the side of the reservoir tube 1 through this interface, it can ensure that the cover can rotate smoothly on the side of the tube. A flexible sealing ring 43 is glued to the edge of the large end interface of the cover for fitting against the skin around the patient's lips.

[0034] To ensure the stability of the connection between the sealing cover 41 and the liquid storage tube 1, a positioning button 44 is threaded onto the outer wall of the small end interface of the sealing cover 41. At the same time, multiple positioning holes 45 are equidistantly opened along the axial direction on the outer circumference of the front end of the liquid storage tube 1. When the sealing cover 41 is installed at the front end of the liquid storage tube 1, the positioning button 44 is tightened so that its end is inserted into the corresponding positioning hole 45, thereby fixing the sealing cover 41.

[0035] Inside the sealing cover 41, near the outer edge, there is a water collection port 42 that extends to the outside, which is used to connect a negative pressure suction device when needed to suck away any small amount of liquid or saliva that may spill out.

[0036] The working principle of the mouthwash device for alleviating radiation-induced oral mucositis proposed in this embodiment is as follows: When in use, the therapeutic medium (liquid mouthwash) is supplied by an external supply device through a flexible infusion tube 2 and its first connector 21 to the channel 2 12 at the end of the reservoir tube 1. Since the inner diameter of the channel 2 12 is larger than that of the channel 1 11 at the front end, and the sealing ring 32 at the end of the connecting tube 31 maintains a sliding seal with the inner wall of the channel 2 12, the liquid is guided and can only enter the connecting tube 31 forward. The liquid flows through the connecting tube 31 to the spray tube 34 at the front end, and after pressure is formed inside it, the liquid is broken into fine droplets by multiple atomizing nozzles 341 that are opened around its periphery, forming a gentle atomized spray that directly acts on the mucosal wound in the patient's oral cavity. This ensures that the liquid covers the wound and avoids secondary damage to the damaged mucosa caused by direct liquid flow.

[0037] To control the flow rate, before use, the knob 354 at the front end of the spray tube 34 can be rotated to drive the internal adjustment mechanism 35 (three strip plates 351) to rotate synchronously. The rotation of the strip plates 351 will partially or completely cover or fully expose the atomizing nozzles 341 behind them, thereby achieving stepless adjustment of the atomizing flow rate and the number of effective working nozzles to meet the needs of different treatment stages and oral areas.

[0038] During the atomization process, in order to ensure that the mouth can receive a sufficient rinsing effect, with the front end of the connecting tube 31 fully extended, the ball 14 is allowed to pass over one of the slide rail rings 311 and enter between the two slide rail rings 311. At this time, the ball 14 engages with the toothed grooves 312 between the two. By rotating the ball 14, the connecting tube 31 drives the spray tube 34 to rotate, thereby adjusting the spray angle of the atomizing nozzle 341 to cover the entire oral cavity.

[0039] When the water atomized to the inner wall of the mouth condenses into beads, the patient can lower their head and expel the beads and saliva into the sealing cover 41, where they are then sucked away by the negative pressure suction device installed at the water collection interface 42.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
