Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a nasal cleaning and disinfection device for otolaryngology. Background Art

[0002] The nasal decontamination device is a tool used to clean and treat nasal and sinus diseases. It delivers decontamination liquid to the nasal cavity under a certain pressure to help remove accumulated secretions and relieve inflammation and allergy symptoms.

[0003] There are many radioactive particles, radioactive dust, and chemical poisons suspended in the air at the site of a nuclear accident. Once inhaled by on-site personnel or drifting into the human body's external cavity, they may enter the human body and cause internal radiation contamination and chemical damage. At present, clinical medicine has no effective solution for this type of injury, and prevention and treatment are still the main focus. Therefore, the status of decontamination in the treatment of nuclear accidents is very important, and the demand for refined decontamination of the nasal cavity is becoming more and more urgent. Complete decontamination and thorough decontamination are the primary contents of reducing nuclear damage and conducting nuclear treatment. At present, the whole body external decontamination of nuclear injured patients has always been valued in the treatment work, and the operating procedures are becoming increasingly standardized, but for the fine and thorough decontamination of the nasal cavity that is exposed and susceptible to nuclear damage, no relevant equipment has been retrieved.

[0004] It is difficult to disinfect the nasal cavity when a nuclear accident occurs, because the location is deep, hidden and narrow, the structure is complex, and there is the influence of hair in the nasal cavity. If conventional disinfection is used, the hair may drive radioactive particles, radioactive dust, chemical poisons and other particles to move toward the back of the nasal cavity. Since these particles may stick to the hair and are not easy to fall off, this may cause radioactive particles, radioactive dust, chemical poisons and other particles to block the posterior nostril, thereby affecting the cleaning waste liquid from entering the other nasal cavity and being discharged. On the one hand, it reduces the disinfection efficiency. On the other hand, radioactive particles, radioactive dust, chemical poisons and other particles blocking the posterior nostril may cause discomfort to the user, and may also cause secondary pollution, aspiration or even suffocation.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0019] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0020] like Figure 1-Figure 5 As shown, a nasal cleaning device for otolaryngology includes a housing 1, a nasal cleaning tube 2 and a suction tube 3, and the device also includes: A liquid separation component 6 is installed inside the nasal wash tube 2; The nasal washing tube 5 is connected to the liquid dispensing component 6, the nasal washing tube 5 is communicated with the liquid dispensing component 6, and the nasal washing tube 5 is located in the nasal washing tube 2; Liquid spraying channel 21, a plurality of liquid spraying channels 21 are provided in the wall of the nasal washing tube 2, the liquid inlet end of the liquid spraying channel 21 is connected to the liquid separation component 6, the liquid outlet end of the liquid spraying channel 21 is located at the top of the nasal washing tube 2, and the liquid outlet end of the liquid spraying channel 21 is inclined in a direction away from the nasal washing tube 2; A cleaning brush 7 is provided on the periphery of the nasal washing tube 5; A driving mechanism 8 is installed in the nasal washing tube 2, and the driving mechanism 8 drives the nasal washing tube 5 to rotate and move up and down; A waste barrel 11 is provided in the shell 1, and the waste barrel 11 is connected to the nasal wash barrel 2 and the suction barrel 3. A liquid storage bin 10 is formed between the waste barrel 11 and the shell 1. A liquid pump 12 is installed in the liquid storage bin 10. A liquid suction tube 13 is connected to the liquid suction pump 12. The liquid suction tube 13 passes through the waste barrel 11 and is connected to the liquid separation component 6. A waste liquid pump 14 is installed in the suction barrel 3.

[0021] In one case of the present embodiment, rubber plugs 4 are provided on the periphery of the nasal wash tube 2 and the suction tube 3 to prevent leakage of cleaning liquid or waste; a liquid injection tube 15 is provided on the shell 1 to facilitate the addition of cleaning liquid into the liquid storage tank 10; a discharge pipe 16 is connected to the waste tube 11, and the discharge pipe 16 runs through the shell 1 to facilitate the discharge of waste; in addition, a power supply and a control panel are also provided in the shell 1, and the power supply provides power to the liquid extraction pump 12, the waste liquid pump 14 and the driving mechanism 8, and the control panel is used to control the start and stop of the liquid extraction pump 12, the waste liquid pump 14 and the driving mechanism 8.

[0022] In actual application of this embodiment, the nasal wash tube 2 is inserted into one nostril of the user, and the suction tube 3 is inserted into the other nostril, and the rubber plug 4 is ensured to fit tightly with the nostril to prevent leakage; then the driving mechanism 8 is controlled to move the nasal wash tube 5 upward, so that the cleaning brush 7 originally located in the nasal wash tube 2 moves up to the top of the nasal wash tube 2, and the cleaning brush 7 is unfolded to contact the inner wall of the nasal cavity, and then the driving mechanism 8 is controlled to rotate the nasal wash tube 5, and at the same time, the liquid extraction pump 12 is controlled to extract the cleaning liquid in the liquid storage tank 10 to the liquid separation component 6 through the liquid extraction pipe 13, and then through the liquid extraction pipe 13, the cleaning liquid in the liquid storage tank 10 is extracted ... The dry liquid spray channel 21 sprays into the nasal cavity, and the cleaning liquid sprayed from the liquid spray channel 21 washes and disinfects the hair on the inner wall of the nasal cavity, and softens the radioactive particles, radioactive dust, chemical poisons and other particles adhering to the hair. The cleaning brush 7 cleans the hair, so that the radioactive particles, radioactive dust, chemical poisons and other particles adhering to the hair are cleaned off. The cleaned radioactive particles, radioactive dust, chemical poisons and other particles, together with the waste liquid, pass through the nasal washing tube 2 into the waste container 11, and finally the nasal washing tube is driven by the driving mechanism 8. The tube 5 moves downward, so that the cleaning liquid passes through the nasal cleaning tube 5 to clean the inside of the nasal cavity, and the waste liquid from the cleaning flows out from the other nasal cavity, and is drawn by the waste liquid pump 14 through the suction tube 3 and enters the waste tube 11; before the inside of the nasal cavity is formally cleaned, the hair is cleaned, so that on the one hand, the inside of the nasal cavity can be preliminarily cleaned, and the hair can also be cleaned, thereby improving the cleaning effect; on the other hand, the radioactive particles, radioactive dust, chemical poisons and other particles adhering to the hair can be cleaned off, thereby preventing the radioactive particles entering the nasal cavity from entering. The fallen ash, radioactive or chemical poison dust can be cleaned meticulously and thoroughly to reduce the risk of internal radiation and the residual chemical poisons. At the same time, when the inside of the nasal cavity is formally cleaned and disinfected later, it can effectively avoid the hair from directly driving radioactive particles, radioactive dust, chemical poisons and other particles to block the posterior nostril when the inside of the nasal cavity is cleaned and disinfected, and avoid affecting the cleaning waste liquid from entering the other nasal cavity and being discharged, thereby improving the cleaning efficiency and not easily causing discomfort to the user during cleaning, avoiding secondary pollution, aspiration and even suffocation.

[0023] When cleaning hair, the cleaning brush 7 can separate the hair that sticks together and make the hair evenly distributed and neat, which can ensure the normal swing of the hair, thereby ensuring the filtering performance of the hair, and also effectively prevent the subsequent radioactive particles, radioactive dust, chemical poisons and other particles from sticking to multiple hairs, thereby reducing the pain caused by cleaning the hair.

[0024] Further, the liquid separation component 6 includes: The cylinder 61, the nasal washing tube 5 is sleeved in the cylinder 61, the bottom of the cylinder 61 is provided with a liquid inlet hole 611, and the liquid extraction tube 13 is connected to the liquid inlet hole 611; Ear plates 62, a plurality of ear plates 62 are arranged on the periphery of the cylinder 61, the other side of the ear plates 62 is fixed to the inner wall of the nasal washing tube 2, and a guide channel 621 is opened on the ear plates 62, the guide channel 621 is connected to the inside of the cylinder 61, and the guide channel 621 is connected to the liquid inlet end of the liquid spraying channel 21; A plurality of through holes 52 are formed on the periphery of the nasal washing tube 5 . When the nasal washing tube 5 moves upward, the plurality of through holes 52 are blocked by the inner wall of the cylinder 61 .

[0025] In actual application of this embodiment, the cleaning liquid enters the cylinder 61 through the liquid inlet hole 611, and then enters the plurality of liquid spraying channels 21 through the plurality of flow guide channels 621; when cleaning the hair, the nasal washing tube 5 moves upward, so that the plurality of through holes 52 are blocked by the inner wall of the cylinder 61, so that the nasal washing tube 5 is in a closed state when the hair is washed and disinfected, and only the plurality of liquid spraying channels 21 are passed through the cleaning liquid. After the nasal washing tube 5 moves downward, the plurality of through holes 52 are located in the cylinder 61 and are connected with the flow guide channels 621, so that the cleaning liquid can enter the nasal washing tube 5 through the through holes 52; in this way, the hair cleaning and the nasal washing and disinfecting are carried out step by step, which can reduce the amount of cleaning liquid used and avoid waste on the one hand, and reduce the stimulation to the nasal cavity on the other hand. If the cleaning brush 7 cleans the hair and washes the nasal cavity at the same time, it may cause discomfort to the user, so that the user can adapt.

[0026] Furthermore, a backflow prevention member 211 is installed at the liquid outlet end of the liquid spray channel 21 .

[0027] In one case of this embodiment, the backflow prevention member 211 is a prior art and will not be described in detail here.

[0028] In actual application of this embodiment, the backflow prevention member 211 can prevent the waste liquid from being cleaned from entering the spray channel 21, effectively preventing the spray channel 21 from being contaminated and producing bacteria, and preventing these bacteria from entering the user's nasal cavity and causing nasal infection when the device is used next time.

[0029] Furthermore, the cleaning brush 7 is composed of a plurality of groups of brushes, and there is a certain gap between two adjacent groups of brushes.

[0030] In one aspect of this embodiment, there is also a certain gap between two adjacent ear plates 62 .

[0031] In actual application of this embodiment, the cleaned radioactive particles, radioactive dust, chemical poisons and other particles can enter the nasal washing tube 2 through the gap between two adjacent groups of brushes, and enter the waste tube 11 through the gap between two adjacent ear plates 62, so as to facilitate the collection of waste; at the same time, reducing the number of brushes can reduce the irritation of the nasal cavity and avoid too many brushes contacting the inner wall of the nasal cavity to cause discomfort to the user.

[0032] like Figure 6 As shown, the driving mechanism 8 comprises: A protective shell 81, a ring 83 is provided on one side of the protective shell 81, and the ring 83 is slidably sleeved on the outer periphery of the nasal washing tube 5, and a fixing rod 82 is provided on the other side of the protective shell 81, and an annular guide groove 22 is opened on the inner wall of the nasal washing tube 2, and the fixing rod 82 is slidably installed in the guide groove 22; The telescopic member 84 is installed in the protective shell 81, the output end of the telescopic member 84 passes through the top of the protective shell 81, the outer periphery of the first output end of the telescopic member 84 is provided with a sleeve shell 841, and the outer periphery of the nasal washing tube 5 is provided with a fixed block 54, and the fixed block 54 is sleeved in the sleeve shell 841; Rotating member 85 is installed in protective shell 81, and the output end of rotating member 85 extends outside protective shell 81. The output end of rotating member 85 is provided with main gear 851, and the outer periphery of nasal washing tube 5 is slidably sleeved with slave gear 86, and main gear 851 and slave gear 86 are meshed with each other.

[0033] Furthermore, the top and bottom of the main gear 851 are both provided with limit plates 852, the slave gear 86 is located between the two limit plates 852, and the two limit plates 852 are respectively in contact with the top and bottom of the slave gear 86, a plurality of guide columns 53 are provided on the periphery of the nasal washing tube 5, the slave gear 86 is sleeved outside the plurality of guide columns 53, and the slave gear 86 moves up and down along the guide columns 53.

[0034] 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 . The cleaning plate 87 contacts the top of the ear plate 62 .

[0035] In one case of this embodiment, the telescopic member 84 can be a multi-stage cylinder or other components that can be driven in multi-stage telescopic manner. The output end of the telescopic member 84 is located between the two groups of brushes; the rotating member 85 can be a motor or other components that can drive the main gear 851 to rotate.

[0036] In actual application of this embodiment, the first output end of the telescopic member 84 is extended or contracted, so that the sleeve 841 drives the fixed block 54 to move up and down, thereby moving the nasal washing tube 5 up and down; the main gear 851 drives the slave gear 86 to rotate through the rotating member 85, so that the nasal washing tube 5 drives the cleaning brush 7 to rotate, and when the nasal washing tube 5 rotates, the fixed block 54 also rotates, so that the fixed block 54 drives the telescopic member 84 to rotate, so that the fixed rod 82 slides in the guide groove 22, so that when the nasal washing tube 5 rotates, the driving mechanism 8 rotates around the nasal washing tube 5 as a whole; When the nose washing tube 5 moves up and down, the position of the slave gear 86 remains unchanged due to the restriction of the two limit plates 852; When the driving mechanism 8 rotates around the nasal wash tube 5, the cleaning plate 87 cleans the tops of several ear plates 62, which can effectively prevent the waste liquid from being blocked between two adjacent ear plates 62, thereby ensuring that the waste liquid enters the waste barrel 11 normally, improving the waste liquid collection efficiency, and indirectly improving the disinfection efficiency.

[0037] like Figure 7 As shown, a blocking mechanism 9 is installed on the top of the nasal washing tube 5, and the blocking mechanism 9 includes: The movable ring 91 is sleeved on the outer periphery of the nasal washing tube 5. When the nasal washing tube 5 moves upward, the second output end of the telescopic member 84 abuts against the bottom of the movable ring 91; The top of the output end of the telescopic member 84 is slidably connected to the bottom of the movable ring 91; A plurality of support rods 92 are rotatably mounted on the periphery of the nasal washing tube 5; A plurality of movable rods 93 are rotatably mounted on the top of the movable ring 91, and the other end of the movable rod 93 is rotatably connected to the bottom of the support rod 92 at the same plane position; A plurality of arc plates 94 are installed on the periphery of the plurality of support rods 92; The elastic rubber membrane 95 is coated on the plurality of arc-shaped plates 94 . One end of the elastic rubber membrane 95 is sealedly connected to the periphery of the nasal washing tube 5 , and the other end is sealedly connected to the surface of the movable ring 91 .

[0038] In one case of this embodiment, the elastic rubber membrane 95 can be made of a sealing material with elasticity, and the arc-shaped plate 94 can be made of a deformable material, so as to adapt to the expansion and contraction of the plurality of support rods 92 .

[0039] In actual application of this embodiment, when the telescopic member 84 drives the nasal washing tube 5 to move upward, the first output end of the telescopic member 84 drives the fixed block 54 through the sleeve 841 to move the nasal washing tube 5 to the moving distance and then stop, and at the same time, the second output end extends, and the second output end slowly approaches the movable ring 91 and pushes the movable ring 91 to move upward. The upward movement of the movable ring 91 will drive the plurality of movable rods 93 to move upward, and the upward movement of the plurality of movable rods 93 will drive the plurality of support rods 92 to rotate outward and expand, so that the elastic rubber membrane 95 is expanded outward through the arc plate 94, so that the edge of the elastic rubber membrane 95 is aligned with the inner wall of the nasal cavity. In this way, a sealed space can be formed when the hair is cleaned, and the posterior nasal cavity is sealed, so that the radioactive particles, radioactive dust, chemical poisons and other particles cleaned from the hair can only enter the waste container 11 together with the waste liquid through the nasal washing tube 2, thereby preventing the radioactive particles, radioactive dust, chemical poisons and other particles from entering the posterior nasal cavity and causing the posterior nasal cavity to be blocked, reducing the irritation to the nasal cavity, and preventing the waste liquid from entering the other nasal cavity and being discharged when the cleaning brush 7 cleans the hair, further reducing the irritation to the nasal cavity, and effectively avoiding causing discomfort to the user; In addition, the elastic rubber membrane 95 is unfolded and pressed against the inner wall of the nasal cavity, and cooperates with the rubber plug 4 to press against the nostril, which can effectively prevent the nasal washing tube 2 from falling off from the nostril, improve the stability of the device during use, and avoid leakage.

[0040] like Figure 3 , Figure 5 and Figure 7 As shown, a nose washing head 51 is arranged at the top of the nose washing tube 5, and a plurality of liquid outlet holes inclined outwards are opened on the nose washing head 51.

[0041] In actual application of this embodiment, after cleaning the hair, the cleaning liquid enters the nasal cavity through the plurality of spray channels 21, and the cleaning liquid simultaneously enters the nasal cavity through the nasal cleaning head 51 on the nasal cleaning tube 5, thereby cleaning the inside of the nasal cavity from multiple angles. On the one hand, the cleaning effect is improved, and on the other hand, it is avoided that only one position is cleaned, resulting in a large impact force of the cleaning liquid, thereby reducing the irritation to the nasal cavity.

[0042] The above shows and describes 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, and the above embodiments and descriptions are only for explaining the principles of the present invention.
