Nasopharyngeal washing device for otolaryngology

Abstract

The application belongs to the technical field of medical devices, and provides a nasal cavity decontamination device for otolaryngology, which comprises a liquid distribution assembly, a nasal washing tube, a liquid spraying channel, a cleaning brush and a driving mechanism. The hair is washed before formal decontamination of the nasal cavity, so that radioactive fallout, radioactive or chemical toxic dust, etc. entering the nasal cavity can be thoroughly and finely washed and removed from the hair, reducing the risk of internal radiation and reducing chemical toxic residue. At the same time, when the nasal cavity is formally decontaminated later, the hair can effectively prevent radioactive particles, radioactive dust, chemical toxic particles, etc. from blocking the posterior naris when the nasal cavity is directly decontaminated, avoiding affecting the entry of the cleaning waste liquid into the other nasal cavity and the discharge, thereby improving the decontamination efficiency, and avoiding discomfort for the user during decontamination, avoiding secondary pollution, aspiration and even suffocation.

Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and in particular relates to a nasal cavity cleaning and disinfection device for otolaryngology. Background Technology

[0002] A nasal irrigation device is a tool used to clean and treat nasal and sinus diseases. It uses pressure to deliver an irrigation solution into the nasal cavity, helping to remove accumulated secretions and reduce inflammation and allergy symptoms.

[0003] At the site of a nuclear or chemical accident, the air contains numerous radioactive particles, radioactive dust, and chemical toxins. If inhaled or carried into external cavities, these substances can enter the body, causing internal radiation contamination and chemical damage. Currently, clinical medicine lacks effective solutions for such injuries, focusing primarily on prevention and elimination. Therefore, decontamination plays a crucial role in the treatment of nuclear and chemical accident victims, and the need for precise decontamination of the nasal cavity is becoming increasingly urgent. Complete and thorough decontamination is the primary aspect of mitigating nuclear and chemical injuries and providing effective treatment. While the overall external decontamination of nuclear and chemical injury victims is highly valued in treatment and procedures are becoming increasingly standardized, no equipment has yet been found for the precise and thorough decontamination of the exposed and vulnerable nasal cavity.

[0004] Decontamination is difficult in the nasal cavity during a nuclear accident because it is deep, hidden, narrow, and structurally complex, and is also affected by nasal hair. If conventional decontamination is used, the hair may carry radioactive particles, radioactive dust, and chemical toxins toward the back of the nasal cavity. Since these particles may stick to the hair and are not easily removed, they may block the posterior nasal cavity, thus affecting the entry of decontamination waste into the other nasal cavity and its drainage. This reduces decontamination efficiency and may also cause discomfort to the user, secondary contamination, aspiration, or even suffocation. Summary of the Invention

[0026] As a preferred embodiment of the above technical solution, a sealing mechanism is installed at the top of the nasal irrigation tube, the sealing mechanism comprising:

[0027] The movable ring is fitted around the nasal irrigation tube. When the nasal irrigation tube moves upward, the second output end of the telescopic component abuts against the bottom of the movable ring.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] 1. In this invention, by cleaning the hair before formally disinfecting the nasal cavity, the nasal cavity can be preliminarily cleaned, and the hair can be cleaned, improving the cleaning effect. On the other hand, it can remove radioactive particles, radioactive dust, chemical toxins and other particles adhering to the hair, and carry out a fine and thorough cleaning of radioactive dust, radioactive or chemical toxins and other particles that have entered the nasal cavity, reducing the risk of internal irradiation and reducing the residue of chemical toxins. At the same time, it can effectively prevent the hair from carrying radioactive particles, radioactive dust, chemical toxins and other particles that may block the posterior nasal opening when the nasal cavity is directly disinfected, thus preventing the cleaning waste liquid from entering the other nasal cavity and being discharged. This improves the disinfection efficiency and is less likely to cause discomfort to the user during disinfection, avoiding secondary pollution, aspiration or even suffocation.

[0035] 2. In this invention, by performing hair cleaning and nasal cavity disinfection in separate steps, the amount of cleaning solution used can be reduced to avoid waste, and the irritation to the nasal cavity can be reduced. If the cleaning brush is used to clean hair and the nasal cavity is disinfected at the same time, it may cause discomfort to the user. This invention can ensure that the user can adapt.

[0036] 3. In this invention, when cleaning hair, an elastic rubber membrane is unfolded and pressed against the inner wall of the nasal cavity. This creates a sealed space during hair cleaning and seals the posterior nasal cavity. As a result, radioactive particles, radioactive dust, chemical toxins, and other particles cleaned from the hair can only enter the waste container along with the waste liquid through the nasal cleaning tube. This prevents radioactive particles, radioactive dust, chemical toxins, and other particles from entering the posterior nasal cavity and causing blockage, thus reducing nasal irritation. At the same time, it prevents waste liquid from entering the other nasal cavity and being discharged when cleaning hair with the cleaning brush, further reducing nasal irritation and effectively avoiding discomfort to the user.

[0046] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0047] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0048] like Figures 1-5 As shown, an otolaryngology nasal cavity cleaning and disinfection device includes a housing 1, a nasal cleaning tube 2, and a suction tube 3. The device further includes:

[0049] Dispensing component 6 is installed inside the nasal irrigation tube 2;

[0050] Nasal irrigation tube 5 is connected to the liquid dispensing component 6. The nasal irrigation tube 5 is connected to the liquid dispensing component 6 and is located inside the nasal irrigation tube 2.

[0051] The nasal irrigation tube 2 has several spray channels 21 inside its wall. The inlet end of the spray channel 21 is connected to the liquid distribution component 6. The outlet end of the spray channel 21 is located at the top of the nasal irrigation tube 2, and the outlet end of the spray channel 21 is inclined away from the nasal irrigation tube 2.

[0052] Cleaning brush 7 is installed around the nasal irrigation tube 5;

[0053] Drive mechanism 8 is installed inside the nasal irrigation tube 2. Drive mechanism 8 drives the nasal irrigation tube 5 to rotate and move up and down.

[0054] The housing 1 is equipped with a waste cylinder 11, which is connected to the nasal irrigation cylinder 2 and the suction cylinder 3. A liquid storage chamber 10 is formed between the waste cylinder 11 and the housing 1. A liquid pump 12 is installed in the liquid storage chamber 10. A liquid pump 13 is connected to the liquid pump 12. The liquid pump 13 passes through the waste cylinder 11 and is connected to the liquid separation assembly 6. A waste liquid pump 14 is installed in the suction cylinder 3.

[0055] In one embodiment, rubber plugs 4 are provided around both the nasal irrigation tube 2 and the suction tube 3 to prevent leakage of cleaning fluid or waste. An injection pipe 15 is provided on the housing 1 to facilitate the addition of cleaning fluid to the storage tank 10. A discharge pipe 16 is connected to the waste tube 11 and passes through the housing 1 to facilitate the discharge of waste. In addition, a power supply and control panel are provided inside the housing 1. The power supply provides power to the liquid pump 12, the waste pump 14 and the drive mechanism 8, and the control panel is used to control the start and stop of the liquid pump 12, the waste pump 14 and the drive mechanism 8.

[0056] In practical application, the nasal irrigation tube 2 is inserted into one nostril of the user, and the suction tube 3 is inserted into the other nostril, ensuring that the rubber stopper 4 fits tightly against the nostril to prevent leakage. Then, the drive mechanism 8 is controlled to move the nasal irrigation tube 5 upward, causing the cleaning brush 7, originally located inside the nasal irrigation tube 2, to move above the nasal irrigation tube 2 and unfold to contact the inner wall of the nasal cavity. Next, the drive mechanism 8 is controlled to rotate the nasal irrigation tube 5, while the suction pump 12 is controlled to draw the cleaning solution in the storage tank 10 through the suction tube 13 to the dispensing assembly 6, and then through several... The dry spray channel 21 sprays the cleaning solution into the nasal cavity. The cleaning solution sprayed from the spray channel 21 washes and disinfects the hair on the inner wall of the nasal cavity, while softening particulate matter such as radioactive particles, radioactive dust, and chemical toxins adhering to the hair. Combined with the cleaning brush 7, the hair is swept clean, removing the radioactive particles, radioactive dust, and chemical toxins adhering to it. The removed radioactive particles, radioactive dust, and chemical toxins, along with the waste solution, enter the waste container 11 through the nasal irrigation tube 2. Finally, the drive mechanism 8 drives the nasal irrigation... The tube 5 is lowered, allowing the cleaning solution to flush the inside of the nasal cavity through the nasal irrigation tube 5. The waste liquid from the flushing flows out from the other nasal cavity and is drawn into the waste container 11 through the suction cylinder 3 by the waste liquid pump 14. Before the formal flushing of the inside of the nasal cavity, the hair is cleaned. This not only provides preliminary cleaning of the inside of the nasal cavity but also cleans the hair, improving the cleaning effect. Furthermore, it removes radioactive particles, radioactive dust, chemical toxins, and other particulate matter adhering to the hair, thus preventing radioactive substances from entering the nasal cavity. The system thoroughly cleans away dust, radioactive or chemical toxins, reducing the risk of internal irradiation and minimizing chemical residue. It also effectively prevents hair from carrying radioactive particles, dust, or chemical toxins that could block the posterior nasal cavity during subsequent nasal decontamination, thus preventing waste from entering and draining into the other nasal cavity. This improves decontamination efficiency and minimizes discomfort for the user, preventing secondary contamination, aspiration, or even suffocation.

[0057] The cleaning brush 7 can separate tangled hairs and distribute them evenly and neatly when cleaning hair. This ensures the hair can move normally, thus ensuring the filtering performance of the hair. It also effectively prevents radioactive particles, radioactive dust, chemical toxins and other particles from sticking to multiple hairs, thereby reducing the pain caused by hair washing.

[0058] Furthermore, the liquid separation component 6 includes:

[0059] A cylindrical tube 61 is fitted inside a nasal irrigation tube 5. An inlet hole 611 is provided at the bottom of the cylindrical tube 61, and a suction tube 13 is connected to the inlet hole 611.

[0060] Ear plates 62 are provided on the outer periphery of the cylinder 61. The other side of the ear plates 62 is fixed on the inner wall of the nasal washing tube 2. A guide channel 621 is provided on the ear plates 62. The guide channel 621 is connected to the inside of the cylinder 61 and is connected to the liquid inlet end of the spray channel 21.

[0061] The nasal irrigation tube 5 has several through holes 52 on its outer periphery. When the nasal irrigation tube 5 moves upward, the through holes 52 are blocked by the inner wall of the cylinder 61.

[0062] In practical application, the cleaning fluid enters the cylinder 61 through the inlet 611 and then enters the spray channels 21 through the guide channels 621. When cleaning the hair, the nasal irrigation tube 5 moves upward, blocking the through holes 52 on the inner wall of the cylinder 61. Thus, the nasal irrigation tube 5 is in a closed state when cleaning the hair, and only the spray channels 21 allow the cleaning fluid to pass through. After the nasal irrigation tube 5 moves downward, the through holes 52 are located inside the cylinder 61 and are connected to the guide channels 621, allowing the cleaning fluid to enter the nasal irrigation tube 5 through the through holes 52. This allows the cleaning of hair and the cleaning of the nasal cavity to be carried out in steps, which reduces the amount of cleaning fluid used and avoids waste. It also reduces irritation to the nasal cavity. If the cleaning brush 7 cleans the hair and cleans the nasal cavity at the same time, it may cause discomfort to the user. This ensures that the user can adapt.

[0063] Furthermore, an anti-backflow component 211 is installed at the liquid outlet end of the spray channel 21.

[0064] In one embodiment, the anti-backflow component 211 is existing technology, and will not be described in detail here.

[0065] In practical application, the anti-backflow component 211 can prevent the waste liquid from cleaning from entering the spray channel 21, effectively avoiding contamination of the spray channel 21 and the generation of bacteria, and preventing these bacteria from entering the user's nasal cavity and causing nasal infection during the next use of this device.

[0066] Furthermore, the cleaning brush 7 consists of several groups of brushes, with a certain gap between adjacent groups of brushes.

[0067] In one embodiment, there is also a certain gap between two adjacent ear plates 62.

[0068] In practical application, the radioactive particles, radioactive dust, chemical toxins, and other particulate matter removed can enter the nasal irrigation tube 2 through the gap between two adjacent sets of brushes, and pass through the gap between two adjacent ear plates 62 into the waste container 11, thus facilitating waste collection. At the same time, reducing the number of brushes can reduce irritation to the nasal cavity and avoid excessive contact between the brushes and the nasal cavity wall, which may cause discomfort to the user.

[0069] like Figure 6 As shown, the drive mechanism 8 includes:

[0070] The protective shell 81 has a ring 83 on one side, which slides around the nasal irrigation tube 5. The other side of the protective shell 81 has a fixing rod 82. The inner wall of the nasal irrigation tube 2 has an annular guide groove 22, and the fixing rod 82 is slidably installed in the guide groove 22.

[0071] Telescopic component 84 is installed inside the protective shell 81. The output end of the telescopic component 84 passes through the top of the protective shell 81. A sleeve 841 is provided around the first output end of the telescopic component 84. A fixing block 54 is provided around the nasal irrigation tube 5. The fixing block 54 is fitted inside the sleeve 841.

[0072] Rotating component 85 is installed inside the protective shell 81. The output end of the rotating component 85 extends out of the protective shell 81. A main gear 851 is provided at the output end of the rotating component 85. A driven gear 86 is slidably sleeved around the nasal irrigation tube 5. The main gear 851 and the driven gear 86 mesh with each other.

[0073] Furthermore, the main gear 851 is provided with limit plates 852 at both the top and bottom. The driven gear 86 is located between the two limit plates 852, and the two limit plates 852 are in contact with the top and bottom of the driven gear 86 respectively. The nasal irrigation tube 5 is provided with several guide posts 53 around its periphery. The driven gear 86 is sleeved on the several guide posts 53 and moves up and down along the guide posts 53.

[0074] Furthermore, a connecting rod 871 is provided at the bottom of the fixing rod 82, and a cleaning plate 87 is provided at the bottom of the connecting rod 871, with the cleaning plate 87 in contact with the top of the ear plate 62.

[0075] In one embodiment, the telescopic member 84 can be a multi-stage cylinder or other components capable of multi-stage telescopic drive, and the output end of the telescopic member 84 is located between the two sets of brushes; the rotating member 85 can be a motor or other components capable of driving the main gear 851 to rotate.

[0076] In practical application, the first output end of the telescopic member 84 extends or retracts, causing the housing 841 to drive the fixed block 54 to move up and down, thereby causing the nasal irrigation tube 5 to move up and down; the main gear 851 drives the slave gear 86 to rotate through the rotating member 85, thereby causing the nasal irrigation tube 5 to drive the cleaning brush 7 to rotate. When the nasal irrigation tube 5 rotates, the fixed block 54 also rotates, thereby causing the fixed block 54 to drive the telescopic member 84 to rotate, causing the fixed rod 82 to slide in the guide groove 22, so that when the nasal irrigation tube 5 rotates, the entire drive mechanism 8 rotates around the nasal irrigation tube 5.

[0077] When the nasal irrigation tube 5 moves up and down, the position of the gear 86 remains unchanged due to the restriction of the two limiting plates 852;

[0078] When the drive mechanism 8 rotates around the nasal irrigation tube 5, the cleaning plate 87 cleans the top of several ear plates 62. This can effectively prevent waste liquid from clogging between two adjacent ear plates 62, thereby ensuring that the waste liquid enters the waste container 11 normally, improving the waste liquid collection efficiency, and thus indirectly improving the washing and disinfection efficiency.

[0079] like Figure 7 As shown, a sealing mechanism 9 is installed at the top of the nasal irrigation tube 5. The sealing mechanism 9 includes:

[0080] The movable ring 91 is fitted around the nasal irrigation tube 5. When the nasal irrigation tube 5 moves upward, the second output end of the telescopic component 84 abuts against the bottom of the movable ring 91.

[0081] The top of the output end of the telescopic component 84 is slidably connected to the bottom of the movable ring 91;

[0082] Support rod 92, several support rods 92 are rotatably installed around the nasal irrigation tube 5;

[0083] The top of the movable ring 91 is rotatably mounted with several movable rods 93, and the other end of the movable rods 93 is rotatably connected to the bottom of the support rod 92 at the same plane position;

[0084] A curved plate 94, and several support rods 92 are surrounded by several curved plates 94;

[0085] An elastic rubber membrane 95 is covered by several arc-shaped plates 94. One end of the elastic rubber membrane 95 is sealed to the outside of the nasal irrigation tube 5, and the other end is sealed to the surface of the movable ring 91.

[0086] In one embodiment, the elastic rubber membrane 95 may be an elastic sealing material, and the arc plate 94 may be a deformable material, thereby accommodating the unfolding and retraction of the several support rods 92.

[0087] In practical application, when the telescopic component 84 drives the nasal irrigation tube 5 to move upward, the first output end of the telescopic component 84 drives the fixing block 54 through the housing 841 to move the nasal irrigation tube 5 to a certain distance and then stop. At the same time, the second output end extends and slowly approaches the movable ring 91, pushing the movable ring 91 upward. The upward movement of the movable ring 91 will drive several movable rods 93 to move upward. The upward movement of the movable rods 93 will drive several support rods 92 to rotate outward and unfold, thereby causing the elastic rubber membrane 95 to unfold outward through the arc plate 94, so that the edge of the elastic rubber membrane 95 is flush with the inner wall of the nasal cavity. This creates a sealed space during hair washing and seals the posterior nasal cavity, ensuring that radioactive particles, radioactive dust, and chemical toxins removed from the hair can only enter the waste container 11 along with the waste liquid through the nasal washing tube 2. This prevents radioactive particles, radioactive dust, and chemical toxins from entering the posterior nasal cavity and causing blockage, thus reducing nasal irritation. It also prevents waste liquid from entering the other nasal cavity and being discharged when the cleaning brush 7 is cleaning the hair, further reducing nasal irritation and effectively avoiding discomfort for the user.

[0088] In addition, the elastic rubber membrane 95 unfolds and presses against the inner wall of the nasal cavity, and together with the rubber plug 4, it presses against the nostril. This can effectively prevent the nasal irrigation tube 2 from falling off the nostril, improve the stability of the device during use, and prevent leakage.

[0089] like Figure 3 , Figure 5 and Figure 7 As shown, the nasal irrigation tube 5 is provided with a nasal irrigation tip 51 at the top, and the nasal irrigation tip 51 has several outwardly inclined liquid outlet holes.

[0090] In practical application, after cleaning the hair, the cleaning solution enters the nasal cavity through several spray channels 21. At the same time, the cleaning solution enters the nasal cavity through the nasal irrigation tube 5's nasal irrigation tip 51, thereby cleaning and disinfecting the inside of the nasal cavity from multiple angles. This improves the cleaning and disinfection effect and avoids the large impact force of the cleaning solution caused by cleaning only one location, thus reducing the irritation to the nasal cavity.

[0091] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
