Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a nasal irrigation device for rhinitis and sinusitis in the field of otolaryngology. Background Technology

[0002] Nasal irrigation is a common method for treating nasal and sinus diseases. With the popularization of nasal endoscopy, endoscopic nasal surgery has become a routine procedure in otolaryngology. After endoscopic nasal surgery, how to promote the early recovery of the surgical cavity mucosa and prevent surgical cavity adhesion and sinus ostium closure is one of the urgent problems to be solved in clinical practice. Nasal irrigation is an important measure to reduce the above-mentioned postoperative complications.

[0003] Nasal irrigation has been widely used in the treatment of various nasal and sinus diseases, including acute and chronic rhinitis, sinusitis, allergic and non-allergic rhinitis, non-specific nasal symptoms (such as postnasal drip), nasal septum perforation, post-nasal surgery, and post-nasal radiotherapy. It can also be used for the common cold; it is not merely an adjunct treatment but an important component of the overall treatment process. Hypertonic saline nasal irrigation can significantly improve patient symptoms and reduce the use of oral antihistamines. It is recommended that patients with seasonal allergic rhinitis use hypertonic saline nasal irrigation during pollen season. Post-operative nasal irrigation after nasal or sinus surgery can significantly reduce adverse reactions such as mucosal edema and crust formation. After endoscopic sinus surgery for nasal polyps, nasal irrigation and topical corticosteroid nasal sprays can consolidate the efficacy of the endoscopic surgery and reduce the recurrence rate.

[0004] Currently used nasal irrigation devices can only deliver the irrigation solution to the vicinity of the nostrils. The water enters through the nostril, flows through the nasal vestibule, nasal passages, sinus openings, and nasopharynx, and exits through the other nostril, flushing out mucus and foreign objects that have entered the nasal cavity. The main problems with this system are as follows:

[0005] (1) The rinsing solution stays in the nasal cavity for a short time and cannot effectively moisten the nasal cavity;

[0006] (2) The rinsing process causes discomfort to the patient's breathing, and rinsing cannot be carried out continuously;

[0007] (3) The rinsing solution and foreign objects in the nose may enter the mouth, esophagus or even the trachea, causing coughing or vomiting, or even foreign body infection, causing severe discomfort to the patient;

[0008] (4) The rinsing solution has low utilization efficiency, resulting in a large amount of waste;

[0009] (5) The rinse solution will overflow from the mouth and nose, polluting clothes and the environment.

[0010] Therefore, there is an urgent need to design a simple and practical nasal irrigation device for rhinitis and sinusitis in otolaryngology to solve the problems existing in the above-mentioned technologies. Summary of the Invention

[0030] The beneficial effects of this invention are: This invention discloses a nasal irrigation device for rhinitis and sinusitis in otolaryngology. Compared with the prior art, the improvement of this invention lies in:

[0031] This invention designs a nasal irrigation device for rhinitis and sinusitis in otolaryngology, including an irrigation fluid injection mechanism and an inner and outer cannula breathing mechanism that work together. In use:

[0032] 1. By setting up the positioning component, the airbag is used to block the nasopharynx, and the nasal plug is used to block the nostrils, so that the nasal cavity is formed into a closed space, allowing the rinsing solution to fully exert its effect in the nasal cavity and achieve a better rinsing effect.

[0033] 2. Through the structural design of the airbag and the second nasal cannula, breathing can still be done through the nasal cavity even when the nasal cavity is closed, reducing the discomfort caused by mouth breathing.

[0050] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0051] Example 1: Refer to Appendix Figure 1-13 The ENT rhinitis and sinusitis nasal irrigation device shown includes an irrigation fluid injection mechanism for injecting irrigation fluid into one nasal cavity of a patient. The irrigation fluid injection mechanism includes a reservoir bag 1 and a first guiding tube 3. The first guiding tube 3 is connected to the reservoir bag 1 through a delivery tube 2. A nasal cavity delivery component 4 and a nasal cavity foreign body removal component 5 are provided on the first guiding tube 3. The nasal cavity delivery component 4 works in conjunction with the delivery tube 2. In use, irrigation fluid is provided to the patient's nasal cavity through the reservoir bag 1 and the nasal cavity delivery component 4 to clean the nasal cavity. The nasal cavity foreign body removal component 5 relieves pressure in the patient's nasal cavity and removes foreign objects from the nasal cavity.

[0052] Preferably, to facilitate connection between the liquid storage bag 1 and the first guiding pipe 3 during use, and to control the flow and prevent backflow, one end of the liquid delivery pipe 2 is connected to the outlet of the liquid storage bag 1, and the other end is connected to the first guiding pipe 3 through the liquid injection connection pipe 22, thereby achieving connection between the liquid storage bag 1 and the first guiding pipe 3; at the same time, to prevent backflow of the flushing liquid in the first guiding pipe 3 during use and to prevent contamination of the flushing liquid in the liquid storage bag 1, a one-way valve 21 is also provided on the liquid delivery pipe 2 to control the one-way flow of the flushing liquid in the liquid delivery pipe 2.

[0053] Preferably, the nasal infusion assembly 4 is fixedly sleeved at the front end of the first guiding tube 3 and used in conjunction with the patient's nasal cavity, including a cleaning solution infusion sleeve 41 and a nasal plug 42; wherein

[0054] The liquid supply sleeve 41 is sleeved on the outside of the first conductive tube 3 through the liquid injection connection tube 22 and is connected to the liquid injection connection tube 22, forming a liquid supply chamber 43 with a closed front end between the liquid supply sleeve 41 and the first conductive tube 3.

[0055] The nasal plug 42 is fixedly installed on the outside of the infusion sleeve 41 and is used in conjunction with the patient's nostrils to seal the outside of the patient's nasal cavity during irrigation, preventing the irrigation fluid from flowing out of the patient's nostrils and ensuring the irrigation effect.

[0056] Preferably, in order to provide cleaning solution to the patient's nasal cavity, a plurality of liquid inlet holes 412 are provided on the side wall of the liquid inlet sleeve 41 and communicate with the liquid inlet chamber 43. That is, in use, the rinsing solution is sent into the liquid inlet chamber 43 by squeezing the liquid storage bag 1, and finally the rinsing solution is sent into the patient's nasal cavity through the liquid inlet holes 412 to clean the patient's nasal cavity.

[0057] Preferably, in order to effectively remove foreign objects from the nasal cavity during use, a spiral protrusion 411 is provided on the outer wall of the liquid supply sleeve 41, which is used to remove foreign objects from the nasal cavity by rotating the liquid supply sleeve 41 during use.

[0058] Preferably, to facilitate the removal of foreign objects from the patient's nasal cavity during irrigation, or when excessive rinsing fluid or foreign objects are detected in the nasal cavity and need to be removed, the nasal foreign body removal component 5 is designed to include a pressure valve 51 and an outlet plug 52 on the first guide tube 3; wherein

[0059] The pressure valve 51 is installed on the first guide tube 3 to detect the pressure in the first guide tube 3 and automatically opens when the liquid pressure in the nasal cavity is high or reaches the threshold to release pressure and expel foreign objects.

[0060] The outlet plug 52 is located at the tail end of the first guide tube 3. When in use, the end of the first guide tube 3 that extends into the patient's nasal cavity is the inlet end, and the end away from the patient's nasal cavity is the outlet end, so as to discharge excess rinsing fluid or foreign objects.

[0061] Preferably, in order to accelerate the discharge of excess rinsing fluid or foreign objects during use, a negative pressure pump can be installed outside the outlet plug 52 at the tail end of the first guide tube 3 to accelerate the discharge of excess rinsing fluid or foreign objects from the patient's nasal cavity.

[0062] The usage process and operating principle of the flushing fluid injection mechanism described in this embodiment include:

[0063] In use, firstly, the cleaning solution infusion sleeve 41 is inserted into the patient's nasal cavity, and the nasal plug 42 is fixed inside the patient's nostril to seal the outside of the patient's nasal cavity; then, the reservoir bag 1 is squeezed, so that the rinsing solution in the reservoir bag 1 enters the infusion chamber 43 through the delivery tube 2 and the injection connection tube 22, and is delivered to the patient's nasal cavity through the infusion hole 412 to clean the patient's nasal cavity; at the same time, during the process of injecting the cleaning solution into the patient's nasal cavity, when the pressure valve 51 detects that the liquid pressure in the nasal cavity is too high or there are too many foreign objects in the nasal cavity, the pressure valve 51 automatically opens to release pressure and expel foreign objects.

[0064] Example 2: Unlike Example 1, in order to drain the rinsing solution injected into the patient's nasal cavity during nasal irrigation, and to separate the nasal passage from the oral passage to prevent the rinsing solution from entering the patient's oral cavity, making the patient's oral cavity an independent system during irrigation to ensure the irrigation effect, the ENT rhinitis and sinusitis nasal irrigation device also includes an inner and outer cannula breathing mechanism that works in conjunction with the rinsing solution injection mechanism. The inner and outer cannula breathing mechanism is fixed in the patient's other nasal cavity and includes a second guide tube 6, and a rinsing solution discharge component 7 and a positioning component 8 disposed on the second guide tube 6. The rinsing solution discharge component 7 is used in conjunction with the rinsing solution injection mechanism to drain the rinsing solution injected into the patient's nasal cavity through the other nasal cavity. The positioning component 8 is used to position the inner and outer cannula breathing mechanism and to separate the patient's nasal passage from the oral passage to prevent the rinsing solution from entering the patient's oral cavity and causing choking.

[0065] Preferably, to facilitate the separation of the patient's nasal passage and oral passage using the positioning component 8 and the installation of the irrigation fluid discharge component 7, while also facilitating patient breathing during irrigation, the second guiding tube 6 is designed to include a connecting flexible tube 61 and an installation rigid tube 62 that are interconnected. The connecting flexible tube 61 is a corrugated flexible tube structure used to extend into the patient's nasal cavity, reaching the junction of the nasal cavity and oral cavity, and working with the positioning component 8 to position and separate the patient's nasal passage from the oral passage. The installation rigid tube 62 is connected to the irrigation fluid discharge component 7. In use, the second guiding tube 6 serves as a breathing channel for the patient to breathe.

[0066] Preferably, to facilitate the positioning of the connecting hose 61 within the patient's nasal cavity, the positioning component 8 is designed to include an air cylinder 81, an air hose 82, and an air bag 83; wherein the air bag 83 is fixedly disposed on the outer side of the end of the connecting hose 61, placed at the junction of the patient's nasal cavity and oral cavity, and connected to one end of the air hose 82.

[0067] The ventilation hose 82 is connected to the air cylinder 81 and passes through the second conduit 6 to connect to the air bag 83. In use, by pulling the piston of the air cylinder 81, gas is allowed to enter the air bag 83 through the ventilation hose 82. The air bag 83 is used to position the connecting hose 61 in the patient's nasal cavity and at the same time, the air bag 83 separates the patient's nasal passage from the oral passage to ensure the flushing effect.

[0068] Preferably, to facilitate the drainage of the rinsing fluid injected into the patient's nasal cavity by the rinsing fluid injection mechanism, the rinsing fluid drainage assembly 7 is designed to include a fluid discharge rotating head 71, a fluid discharge head 72, and a fluid discharge connector 73; wherein

[0069] The liquid discharge head 72 is installed at the tail end of the rigid tube 62, and an opening is made in the middle of the liquid discharge head 72 to facilitate patient breathing and fixation of the ventilation hose 82.

[0070] The liquid outlet rotary head 71 is sleeved on the outside of the mounting rigid tube 62 and is located between the liquid outlet drain head 72 and the liquid outlet connector 73. It is connected to the liquid outlet drain head 72 through the plug connector 712. The liquid outlet connector 73 is provided with a drain chamber 714 and a drain port 711 that are interconnected, so that the flushing liquid in the liquid outlet rotary head 71 can be discharged through the drain port 711. As needed, a plug or a negative pressure pump can be provided on the drain port 711.

[0071] The liquid outlet connector 73 is a frustum-shaped structure sleeved inside the liquid outlet rotating head 71 and outside the mounting rigid tube 62. It is connected to the liquid outlet rotating head 71 through the insertion groove 715. The liquid outlet connector 73 is provided with a third drainage channel 731 that communicates with the patient's nasal cavity, so that when in use, the nasal irrigation fluid can form a rapid and complete circulation in the nasal cavity starting from the two nostrils.

[0072] Preferably, to ensure the rinsing solution can permeate the patient's nasal cavity during use and maintain a continuous rinsing effect, the discharge head 72 is further provided with several second discharge channels 721. The second discharge channels 721 cooperate with the first discharge channel 713 located in the discharge rotating head 71. The first discharge channel 713 is connected to the discharge chamber 714. That is, during use, by rotating the discharge head 72, the second discharge channels 721 and the first discharge channels 713 are aligned to form a slower circulation, and the rinsing solution is discharged into the collection container through the guide nozzle 722. When the discharge port 711 is used as the discharge outlet, the discharge head 72 and the discharge rotating head 71 can be rotated to separate the second discharge channels 721 and the first discharge channels 713, forming a closed space (a negative pressure pump or plug is installed at the discharge port 711).

[0073] Preferably, in order to seal the patient's nasal cavity, the liquid outlet connector 73 is designed as a platform structure, that is, it can be tightly locked in the patient's nasal cavity during use, and ensure that the third drainage channel 731 can smoothly enter and exit liquid.

[0074] Preferably, to ensure a cleaning effect on the nasal cavity when flushing, a rotating component 9 is rotatably mounted on the mounting tube 62. The rotating component 9 has a sleeve-shaped structure and is rotatably positioned on the outside of the mounting tube 62 via a positioning protrusion 621 on the mounting tube 62. Several guide grooves 91 are inclinedly arranged on the outside of the rotating component 9. In use, the impact generated by the flushing fluid flowing in the guide grooves 91 drives the rotating component 9 to rotate, cleaning the deposits in the nasal cavity. In addition, its spiral structure can be used to create a vortex in the water flow, resulting in a better flushing effect.

[0075] Combining the inner and outer cannula breathing mechanism described in this embodiment and the flushing fluid injection mechanism described in Embodiment 1, four flushing modes can be achieved during use, including:

[0076] 1. Rapid circulation of multiple foreign objects in a single nostril

[0077] As described in Example 1, during use, the cleaning fluid supply sleeve 41 is inserted into the patient's nasal cavity, so that the nasal plug 42 is fixed in the patient's nostril, sealing the outside of the patient's nasal cavity; then the storage bag 1 is squeezed, so that the rinsing fluid in the storage bag 1 enters the supply chamber 43 through the delivery tube 2 and the injection connection tube 22, and is delivered to the patient's nasal cavity through the supply hole 412 to clean the patient's nasal cavity; at the same time, during the process of injecting the cleaning fluid into the patient's nasal cavity, when the pressure valve 51 detects that the liquid pressure in the nasal cavity is large or there are many foreign objects in the nasal cavity, the pressure valve 51 automatically opens to release pressure and expel foreign objects, realizing rapid circulation of multiple foreign objects in a single nostril;

[0078] 2. Rapid circulation through both nostrils

[0079] As described in this embodiment, in conjunction with the irrigation fluid injection mechanism, starting from the patient's two nostrils, the airbag 83 is used to separate the patient's nasal passage from the oral passage. Then, the reservoir bag 1 is squeezed so that the irrigation fluid in the reservoir bag 1 enters the infusion chamber 43 through the delivery tube 2 and the injection connection tube 22. The irrigation fluid is delivered to the patient's nasal cavity through the infusion hole 412. After cleaning the patient's nasal cavity, the irrigation fluid is discharged sequentially through the third drainage channel 731, drainage chamber 714 and drainage hole 711 in the other nasal cavity by the suction action of the negative pressure pump installed at the drainage port 711, thus completing the rapid circulation of the two nostrils.

[0080] 3. Slow circulation through both nostrils

[0081] Based on the rapid circulation through both nostrils, the negative pressure pump is turned off, and the liquid outlet head 72 is rotated so that the second liquid outlet channel 721 is aligned with the first liquid outlet channel 713. At this time, the flushing liquid is discharged sequentially through the third liquid outlet channel 731, the liquid outlet chamber 714, the second liquid outlet channel 721, and the guide nozzle 722, completing the slow circulation through both nostrils.

[0082] 4. Long-term residence mode of liquid medicine in a closed space

[0083] Based on the slow circulation mode of the two nostrils, the liquid outlet head 72 is rotated so that the second liquid outlet channel 721 is misaligned with the first liquid outlet channel 713 to form a closed space. At this time, the flushing liquid is blocked from the first liquid outlet channel 713 through the third liquid outlet channel 731 and the liquid outlet chamber 714, thus completing the effect of long-term immersion of the medicine in the closed space.

[0084] The operating principle and process of the ENT rhinitis and sinusitis nasal irrigation device, which combines the inner and outer cannula breathing mechanism described in this embodiment and the irrigation fluid injection mechanism described in Embodiment 1, include:

[0085] 1. Mix the rinsing solution well and adjust it to a suitable temperature;

[0086] 2. Connect the device and select the appropriate connection mode based on the patient's condition;

[0087] 3. After applying medical lubricant to the surfaces of the ventilation tubing 82 and the cuff 83, insert them into the patient's nasal cavity and inflate the cuff 83 in the nasopharynx to form a septum;

[0088] 4. Confirm that the patient can breathe through the second cannula 6 after the airbag 83 is cut off;

[0089] 5. After lubricating the first cannula 3, insert it into the other nostril and seal the nasal cavity with the nasal plug 42;

[0090] 6. Squeeze the reservoir bag 1 to allow the rinsing solution to enter the nasal cavity, and rinse as needed.

[0091] When using the nasal irrigation device for rhinitis and sinusitis described in Embodiments 1 and 2 of this invention:

[0092] 1. It can be used as a rinsing device or a medicine soaking device, allowing the medicine to stay in the nasal cavity for a longer time without entering the mouth and throat, thus avoiding infection and medicine waste;

[0093] 2. After the nasal cavity has been continuously moistened by the rinsing solution, the first guide tube 3 can be rotated to physically clean the area in contact with the nasal cavity and remove the adhering substances without injecting liquid.

[0094] 3. If conditions permit, a miniature ultrasonic vibration probe can be installed at the front end of the conduit 3 to improve the flushing effect using an ultrasonic device.

[0095] 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.
