[0002] Nasal irrigation is a simple and effective way to cleanse the nasal cavity and sinuses to relieve and treat a variety of nasal conditions. By using a gentle saline solution, this irrigation can help thin the mucus in the nasal cavity, remove bacteria, viruses, pollen and other allergens, and reduce inflammation and blockage. Regular nasal irrigation can not only relieve symptoms such as rhinitis and sinusitis, but also help prevent colds and allergic reactions, and is particularly suitable for personal care in dry seasons or polluted environments. In addition, nasal irrigation also has a positive effect on symptoms such as postnasal drip, helping to improve breathing quality and overall comfort.

[0033] In addition, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0034] The utility model provides Figures 1 to 4 As shown in the figure, a nasal irrigator for children is designed to solve the shortcomings of existing nasal irrigators, such as being unable to be operated with one hand and being prone to over-injection of nasal wash solution.

[0035] The children's nasal irrigator mainly includes: an injection part 100, a suction part 200, a connecting part 300 and a valve part 400. The injection part 100 is provided with an injection channel 110, and the opening of the injection channel 110 toward the patient's nostrils is an injection port 111, and the injection channel 110 is used to communicate with a nasal wash solution bottle, preferably, the nasal wash solution bottle is a physiological saline bottle; the suction part 200 is provided with a negative pressure channel 210, and the opening of the negative pressure channel 210 toward the patient's nostrils is a negative pressure port 211, and the negative pressure channel 210 is used to connect a negative pressure device; the connecting part 300 is connected between the injection part 100 and the suction part 200, and is used to fix the injection part 100 and the suction part 200, so that the injection part 100 and the suction part 200 can be grasped and operated with one hand. The valve portion 400 is matched and arranged in the injection channel 110 , and the valve portion 400 is located between the nasal wash solution bottle and the injection port 111 . The valve portion 400 is used to control the flow rate of the nasal wash solution in the injection channel 110 .

[0036] Specifically, when using a children's nasal irrigator to irrigate the nasal cavity, medical staff can pinch the connecting part 300 with one hand, guide the patient's nostrils upward, and then aim the injection port 111 of the injection part 100 and the negative pressure port 211 of the suction part 200 downward at the two nostrils of the patient respectively, bring the injection part 100 and the suction part 200 close to the two nostrils of the patient, and block the two nostrils of the patient with the injection part 100 and the suction part 200. Then, the injection channel 110 can inject nasal wash solution into the patient's nasal cavity, and the negative pressure channel 210 can absorb and discharge the liquid in the patient's nasal cavity, thereby irrigating the patient's nasal cavity.

[0037] It is understandable that after the nasal wash solution flows into the injection channel 110, the nasal wash solution will flow down toward the injection port 111 due to gravity. Preferably, the valve portion 400 has an elastic opening, and the nasal wash solution can flow in small amounts or not at all through the opening. When the valve portion 400 is blocked by the nasal wash solution, for ease of description, the injection channel 110 is divided into a proximal section (towards the medical staff) and a distal section (towards the inside of the patient's nasal cavity) with the valve portion 400 as the boundary. When the negative pressure device is working, the pressure in the nasal cavity decreases, which will cause the pressure in the proximal section to also decrease. At this time, the nasal wash solution will be attracted, so that the nasal wash solution flows quickly into the nasal cavity, and the valve portion 400 is subjected to pressure, which will cause its opening to be stretched, so that the flow rate of the nasal wash solution is increased. When the negative pressure device is not started, the nasal wash solution will not flow into the patient's nasal cavity or a small amount of it will flow into the patient's nasal cavity. When the negative pressure device is working, the nasal wash solution flowing into the nasal cavity can be increased, effectively preventing excessive injection of the nasal wash solution.

[0038] In existing medical practice, nasal irrigation usually involves the use of two separate devices: a saline bottle and a negative pressure suction tube. Medical staff need to use both hands during the operation, which not only increases the complexity of the operation, but may also affect the accuracy and safety of the irrigation. Especially when performing nasal irrigation on children, since it is difficult for them to accurately express discomfort, medical staff often find it difficult to intuitively judge the remaining amount of saline in the nasal cavity, which may cause excessive saline to enter the throat, causing coughing or other uncomfortable reactions. Therefore, there is a lack of a nasal irrigation device on the market that can reduce the risk of aspiration of saline, especially for pediatric patients, and can provide a more comfortable and reliable treatment experience.

[0039] The utility model can integrate the injection part 100 and the suction part 200 by providing a connection part 300, so that medical staff can operate with one hand during the process of flushing the patient's nasal cavity, and children can conveniently use the other hand to adjust their posture; a valve part 400 is also provided, so that the nasal washing solution will not flow into the patient's nasal cavity or a small amount of it will flow into the patient's nasal cavity. When the negative pressure device is working, the nasal washing solution flowing into the nasal cavity can be increased, effectively preventing excessive injection of the nasal washing solution.

[0040] In some embodiments, Figures 1 to 4 As shown in the figure, the radius of the injection part 100 gradually decreases toward the injection port 111 and forms a mushroom head shape, and the radius of the suction part 200 gradually decreases toward the negative pressure port 211 and forms a mushroom head shape. Existing nasal wash solution bottles generally use plastic seals. When the bottle mouth is opened, the edge of the bottle mouth has burrs and is relatively sharp. When medical staff wash the nasal cavity of children, they generally directly insert the bottle mouth into the nasal cavity of the children, which is easy to cut the skin of the nasal cavity of the children. By setting the injection part 100 and the suction part 200 to be mushroom head-shaped, it can effectively prevent the skin of the nasal cavity of the children from being cut.

[0041] In some embodiments, Figure 2 , Figure 4 As shown in FIG. 1 , the valve portion 400 is tubular, and the radius of the valve portion 400 gradually decreases toward the injection port 111 and forms a funnel shape. Preferably, the valve portion 400 is made of silicone.

[0042] In some embodiments, Figure 1 , Figure 2 as well as Figure 4 As shown in , the children's nasal irrigator further includes: a mounting hole 301, the mounting hole 301 is arranged on the injection part 100 or the connecting part 300, the mounting hole 301 is connected to the injection channel 110, and the mounting hole 301 is used to fix the bottle mouth of the nasal washing solution bottle inserted therein;

[0043] Two card slots 302, the two card slots 302 are arranged along the radial direction of the mounting hole 301, and the two card slots 302 are arranged opposite to each other, so as to better fix the bottle mouth of the nasal washing solution bottle in the mounting hole 301;

[0044] The silicone layer is covered on the inner wall of the mounting hole 301 and the slot 302 , so as to better fix the bottle mouth of the nasal wash solution bottle in the mounting hole 301 .

[0045] In some embodiments, Figure 2 , Figure 4 As shown in , the injection part 100 further includes: a buffer chamber 303, which is arranged on the injection part 100 and / or the connecting part 300, and the buffer chamber 303 is connected with the injection channel 110, and the valve part 400 is located between the buffer chamber 303 and the injection port 111. When in use, the nasal wash solution in the nasal wash solution bottle can be injected into the buffer chamber 303 according to a certain amount, so as to facilitate one-handed operation.

[0046] In some embodiments, Figure 1 , Figure 2 as well as Figure 4 As shown in , the injection part 100 further includes: a pressure relief hole 304, one end of which is open to communicate with the outside, and the other end of which is open to communicate with the buffer cavity 303. The injection part 100 can prevent the injection channel 110 from forming a sealed cavity when the nasal wash solution bottle blocks the mounting hole 301, so that the nasal wash solution in the buffer cavity 303 cannot flow into the patient's nasal cavity.

[0047] In some embodiments, Figure 4 As shown in , the nasal irrigator for children also includes: a pressure indicating tube 212, which is arranged in the negative pressure channel 210 along the length direction of the negative pressure channel 210, and the outer diameter of the pressure indicating tube 212 is greater than the inner diameter of the negative pressure channel 210, and air holes are arranged at both ends of the pressure indicating tube 212;

[0048] The pressure indicating ball 213 is arranged in the pressure indicating tube 212. The radius of the pressure indicating ball 213 is larger than the radius of the air hole and smaller than the inner diameter of the pressure indicating tube 212. When the negative pressure device is working, the gas / liquid flow in the negative pressure channel 210 will drive the gas / liquid flow in the pressure indicating tube 212. At this time, the pressure indicating ball 213 will be driven by the gas / liquid in the pressure indicating tube 212 and move away from the negative pressure port 211. When the negative pressure port 211 is blocked, the gas / liquid flow speed in the negative pressure channel 210 slows down or stops. At this time, the gas / liquid flow speed in the pressure indicating tube will also slow down or stop accordingly, so that the pressure indicating ball 213 moves toward the negative pressure port 211 under the action of gravity. By observing the position of the pressure indicating ball 213 in the pressure indicating tube 212, the blockage of the negative pressure port 211 can be intuitively observed to prevent the nasal mucosa from being damaged due to too low pressure inside the patient's nasal cavity.

[0049] An observation window 214 is provided on the suction portion 200 and / or the connection portion 300 . The observation window 214 is used to observe the position of the pressure indicating ball 213 .

[0050] In some embodiments, Figure 4 As shown in , the children's nasal irrigator further includes: an air inlet tube 215, which is arranged in the pressure indicating tube 212;

[0051] The air hole at one end of the pressure indicating tube 212 facing the negative pressure port 211 is an air inlet hole, which is arranged on the side surface of the pressure indicating tube 212, and the air inlet pipe 215 is connected to the air inlet hole, so as to reduce the secretion liquid passing through the pressure indicating tube 212, thereby reducing the probability of blockage of the pressure indicating tube 212.

[0052] In some embodiments, Figure 3 As shown in , the nasal irrigator for children also includes: a buffer groove 305, the buffer groove 305 is connected to the injection part 100 or the connection part 300, the width of the buffer groove 305 gradually decreases toward the bottom of the groove to form a funnel shape, the buffer groove 305 is connected to the injection channel 110, and the buffer groove 305 is used to collect the nasal wash solution in the nasal wash solution bottle. In actual use, the nasal wash solution in the nasal wash solution bottle can be conveniently poured into the buffer groove 305 through the buffer groove 305, and the nasal wash solution flows into the injection channel 110.

[0053] In some embodiments, Figures 1 to 4 As shown in the figure, the shape of the connecting part 300 is U-shaped or M-shaped, and the two ends of the connecting part 300 are respectively connected to the injection part 100 and the suction part 200. Preferably, the connecting part 300 is made of an elastic material, and the distance between the injection part 100 and the suction part 200 can be easily changed by pressing the two ends of the connecting part 300 to meet the requirements of different patients.

[0054] In summary, a nasal irrigator for children is provided, including: an injection part, a suction part, a connection part and a valve part. The injection part is provided with an injection channel for communicating with a nasal wash solution bottle, the suction part is provided with a negative pressure channel for connecting to a negative pressure device, the connection part is connected between the injection part and the suction part, the valve part is matched and arranged in the injection channel, and the valve part is located between the nasal wash solution bottle and the injection port, and the valve part is used to control the flow of the nasal wash solution in the injection channel. The utility model can integrate the injection part and the suction part by providing a connection part, and medical staff can operate with one hand during the process of irrigating the patient's nasal cavity, and the child can conveniently use the other hand to adjust the posture; the valve part is also provided, so that the nasal wash solution will not flow into the patient's nasal cavity or a small amount of it will flow into the patient's nasal cavity, and when the negative pressure device is working, it can increase the nasal wash solution flowing into the nasal cavity, effectively preventing excessive injection of the nasal wash solution.
