Nasal lavage devices of the prior art typically deliver saline or other cleansing fluid under pressure to the nostrils, through the nasal vestibule, sinuses, and nasal passages around the nasopharynx, or out of one nostril, or out of the mouth. Through the above path, pathogenic bacteria and dirt in the nasal cavity are discharged by means of the sterilization effect of physiological saline or other cleaning liquid and the impact force of water flow, so that the aim of cleaning the nasal cavity is fulfilled. Because the rivers get into the back from the nostril of one side, flow or discharge from the oral area from the nostril of opposite side, the rivers are great to the stimulation of nasal cavity, and the nasal cavity is felt stronger foreign matter easily and is got into the sensation, leads to the user to choke easily to, and remain more moisture in the nasal cavity after washing, need longer time just can discharge, the user is lasting to have the foreign matter sense in a period after washing, and the discomfort of user is stronger, and the use of nasal lavage ware experiences inadequately. The nasal lavage device is commonly used for nasal cavity nursing after nasal septum operation, nasal cavity operation and the like, and the nasal lavage device does not need to be washed with high intensity in daily nasal washing. In addition, for example, water enters from one nostril and is discharged from the other nostril, the water needs to flow through the nasal vestibule, the nasal sinuses and other parts in sequence, dirt in the nasal vestibule can be driven to the deep part of the nasal cavity, and infection of the nasal cavity is caused.

In order to solve the above technical problem, referring to fig. 1, in an embodiment of the first aspect of the present application, a nasal wash assembly is provided. The nasal wash assembly includes a plug 100 and a catheter 200, the catheter 200 for delivering a wash solution into the nasal cavity, the plug 100 for occluding the nostril to prevent the wash solution from flowing out of the nostril onto the garment. As shown in fig. 2, the plug 100 includes a main body 120 and an elastic portion 110, the main body 120 and the elastic portion 110 may be integrally made of an elastic material such as silica gel, or the main body 120 and the elastic portion 110 may be separately and then fixedly connected.

For convenience of description, the two axial ends of the main body 120 are respectively designated as a first end 121 and a second end 122, the first end 121 being one end of the main body 120 for insertion into the nasal cavity, and the other end being one end for insertion into the nasal irrigator for connection with the nasal irrigator. One end of the elastic portion 110 is connected to the first end 121 of the main body 120, and the other end extends toward the second end 122 to be a free end, so that the free end of the elastic portion 110 can be elastically deformed with respect to the fixed end. The outer diameter of the elastic portion 110 gradually increases in the direction from the first end 121 to the second end 122, forming a tapered-like structure. The nostril size of different users is different, and conical structure can adapt to different crowds and use, and elastic part 110 can take place elastic deformation, can increase the area of contact of end cap 100 and nostril pore wall on the one hand for end cap 100 can more inseparable closed nostril, avoids the escape of washing liquid, and on the other hand, the shape of nostril is generally not regular circular, and elastic part 110 can take place elastic deformation in order to adapt to the shape of nostril, reduces the clearance between end cap 100 and the nostril pore wall.

Referring to fig. 2 and 3, the main body 120 has a mounting channel 124 extending therethrough in an axial direction, and the catheter 200 is inserted through the mounting channel 124 and extends in the axial direction of the plug 100 to protrude from the first end 121 of the plug 100, so that when the plug 100 blocks the nostril, the catheter 200 can be inserted into the nasal cavity to spray the cleaning solution. The catheter 200 has a liquid guide channel 211 for conveying cleaning liquid, and the outer peripheral surface of the catheter 200 is provided with a liquid outlet 222 communicated with the liquid guide channel 211, and the liquid outlet 222 is communicated with the liquid guide channel 211. The liquid outlet 222 is disposed on the outer peripheral surface of the catheter 200, not on the end surface, so that the cleaning liquid is sprayed radially, and does not spray axially deep into the nasal cavity, thereby reducing the irritation of the spraying of the cleaning liquid to the nasal cavity.

The main body 120 further has a recovery passage 123 extending axially therethrough, and the recovery passage 123 has a recovery port 125 formed at a first end 121 of the main body 120, and the cleaning liquid is ejected from the liquid outlet 222 to flush the inner wall of the nasal cavity. When the nasal lavage device is used, the nasal lavage device is generally held in a vertical posture by a user, and can naturally fall under the action of gravity after washing the inner wall of the nasal cavity with the washing liquid, and the nostrils are closed by the plugs 100, so that the washing liquid cannot escape out of the nasal cavity. The cleaning liquid can be discharged out of the nasal cavity through the recovery port 125, so that swelling feeling caused by accumulation of the cleaning liquid in the nasal cavity is avoided, the used cleaning liquid and dirt carried by the cleaning liquid are recovered and stored in a concentrated mode, and pollution to clothes or body surface skin caused by overflow of the cleaning liquid is avoided.

Based on the above, the catheter 200 is inserted into the nasal cavity, and the liquid outlet 222 sprays the cleaning liquid to flush the peripheral cavity wall of the nasal cavity, so that the nasal cavity is cleaned. Since the cleaning liquid sprayed from the nasal wash assembly is recovered in the nasal cavity on one side, the cleaning liquid does not flow into the nasal cavity on the other side, so that discomfort is caused to a user. And, the washing degree of depth of the nasal wash subassembly of this application is less, can not amass the chamber wall of nasal cavity depths, is applicable to daily nasal cavity nursing.

In some embodiments, referring to fig. 2 and 4, the catheter 200 further includes a tube segment body 210 and a rotary union 220, wherein the rotary union 220 is rotatably coupled to the tube segment body 210, and in particular, the rotary union 220 and the tube segment body 210 may be coupled by a bearing or a ball. The pipe section main body 210 has a liquid guide passage 211 extending in an axial direction, the spin head 220 has a second passage 221 communicating with the liquid guide passage 211, and the second passage 221 extends spirally to an outer circumferential surface of the spin head 220 to form a liquid outlet 222. In the embodiment shown in fig. 4, the rotary nozzle 220 has a plurality of second channels 221, and one end of each second channel 221 is connected to the liquid guiding channel 211, and the other end extends radially to penetrate the rotary nozzle 220. It should be noted that, the second channel 221 extends to the outer circumferential surface of the rotary nozzle 220 along the radial spiral, that is, as shown in fig. 4, the second channel 221 is circular arc-shaped along the projection of the axial direction of the rotary nozzle 220, and when the cleaning solution moves in the second channel 221, the cleaning solution continuously impacts the outer circumferential wall of the circular arc-shaped second channel 221 due to a certain impact force of the cleaning solution, so as to drive the rotary nozzle 220 to rotate. The impact force of the water flow drives the rotary spray head 220 to rotate, and the cleaning liquid is sprayed out in a rotary way, so that 360-degree flushing can be realized.

In some embodiments, the second channel 221 extends in a radial direction, and the cleaning fluid is sprayed onto the spin head 220 in a plane perpendicular to the axis of the spin head 220, and in other embodiments, the second channel 221 extends in an axial direction in addition to the radial direction. Specifically, the rotary sprayer 220 further includes a liquid inlet 223, and along the axial direction of the rotary sprayer 220, the liquid outlet 222 is closer to the plug 100 than the liquid inlet 223, that is, in the embodiment shown in fig. 2, when the catheter 200 is vertically placed, the cleaning liquid flows in the liquid guiding channel 211 from bottom to top, and the position of the liquid outlet 222 is lower than the position of the liquid inlet 223, that is, the second channel 221 extends spirally in the radial direction, and at the same time, there is a change in height in the axial direction, that is, the second channel 221 extends spirally downward, so that the cleaning liquid can be sprayed obliquely downward. Further, the cleaning liquid is sprayed toward the plug 100, and after the inner wall of the nasal cavity is washed, the cleaning liquid can be recovered by the recovery port 125, so that accumulation of the cleaning liquid in the nasal cavity is avoided, and the possibility of irritation caused by the cleaning liquid entering into the deep part of the nasal cavity is reduced.

In some embodiments, the rotary sprayer 220 is disposed at an end of the spool piece body 210 remote from the sprayer, exposed to the nasal cavity. In other embodiments, the rotary sprayer 220 is disposed in the pipe section main body 210, and the pipe wall of the pipe section main body 210 is provided with a dodging groove 212 extending along the circumferential direction, where the dodging groove 212 can be communicated with the second channel 221. The avoiding groove 212 is used for spraying the cleaning solution, so that the avoiding groove 212 should penetrate through the pipe wall of the pipe section main body 210 along the circumferential direction as much as possible to avoid excessive interference with the spraying of the cleaning solution, resulting in dead angles for cleaning in the circumferential direction. In some embodiments, unlike the inclined spraying of the cleaning solution through the second channel 221 extending spirally downward, in other embodiments, the spraying direction of the cleaning solution is adjusted by the inclination angle of the avoidance groove 212 on the pipe section main body 210, as shown in fig. 1 and fig. 2, specifically, the avoidance groove 212 is inclined to penetrate through the pipe wall of the pipe section main body 210, that is, along the axial direction of the pipe section main body 210, the liquid outlet end of the avoidance groove 212 is closer to the plug 100 than the liquid inlet end of the avoidance groove 212, the catheter 200 is vertically placed, for example, the cleaning solution flows in the liquid guide channel 211 from bottom to top, after the cleaning solution is sprayed from the liquid outlet 222 of the rotary spray nozzle 220, the avoidance groove 212 is inclined downward, so as to play a guiding role of the cleaning solution, so that the cleaning solution is sprayed obliquely downward.

In some embodiments, the recovery channel 123 is connected to an external negative pressure source, thereby creating a relatively low pressure at the recovery port 125 to draw the aspiration fluid in the nasal cavity to the recovery port 125. Through negative pressure suction, can guide the orderly flow of washing liquid to, can be through setting up a hysteresis signal for the negative pressure source, promptly after the washing liquid stops spouting, the negative pressure source is continuous to work a period of time then closed to adsorb remaining washing liquid in the nasal cavity, in order to keep the dry and comfortable state in the nasal cavity, avoid wasing the back wet nasal cavity environment and cause user's experience poor.

In some embodiments, as shown in fig. 2, the inner diameter of the liquid guiding channel 211 gradually decreases along the flowing direction of the cleaning liquid, so that the flowing speed and the water pressure of the cleaning liquid gradually increase, thereby realizing high-speed spraying of the water flow, improving the impact force of the water flow, and further improving the cleaning capability of the nasal cleaner. It should be noted that, as referred to herein, the "high-speed spraying" should be that, compared to the cleaning solution at the inlet end of the liquid guiding channel 211, the actual spraying rate can be adjusted by adjusting the pressure of the liquid feeding pump and the caliber of the outlet end of the liquid guiding channel 211, so as to have a certain impact cleaning capability, but not to stimulate the nasal cavity.

In some embodiments, a first flange is provided on the outer peripheral surface of the catheter 200, and the first flange abuts against the end surface of the second end 122 of the main body 120, so as to limit the displacement of the plug 100 relative to the catheter 200, thereby fixing the catheter 200 and the plug 100.

In some embodiments, as shown in fig. 4, the plug 100 has a mounting channel 124 and a plurality of recovery channels 123, each recovery channel 123 being circumferentially disposed around the mounting channel 124, each recovery channel 123 being separated by a connecting portion for connecting the body portion 120 and the elastic portion 110. It should be noted that the main body 120 of the plug 100 further defines a concentration chamber 126, and each recovery channel 123 communicates with the concentration chamber 126, so as to concentrate the waste liquid. In addition, since each recovery channel 123 is connected to the concentration chamber 126, an interface for connecting an external negative pressure source is provided on the concentration chamber 126, so that a negative pressure interface can provide negative pressures of a plurality of recovery channels 123.
