Description

Technical Field

[0001] The utility model relates to the technical field of nasal sprayers, in particular to a physiological seawater nasal sprayer. Background Art

[0002] Physiological seawater is a 0.9% sodium chloride seawater solution. Because its osmotic pressure value is roughly the same as that of normal human plasma and tissue fluid, it can be used for fluid replacement and other medical purposes. Physiological seawater contains a variety of trace elements, so it can be sprayed into the nasal cavity for sterilization and anti-allergic effects. A nasal sprayer is a device that sprays physiological seawater into the nasal cavity. By cleaning the nasal cavity, inhaled allergens attached to the nasal mucosa are removed, which can prevent the onset of allergic rhinitis. Nosebleeds caused by dry nasal mucosa can be moistened by spraying physiological seawater into the nose. It is mainly used to clean more viscous secretions in the nasal cavity, or when there are more dry crusts attached to the front of the nasal cavity. It is a treatment method often used in clinical work.

[0003] After searching, it is found that in a patent publication number CN219878645U, a physiological seawater nasal sprayer with uniform spray is proposed that "the physiological seawater nasal sprayer with uniform spray has a mounting shell at the end of the catheter to prevent liquid backflow, and the screen can prevent block secretions from entering".

[0004] However, the above solution still has certain shortcomings in actual use. When the amount of physiological seawater remaining in the sprayer is small, the straw cannot directly contact the physiological seawater contained in the sprayer, which will result in the physiological seawater in the sprayer not being fully used up, thereby causing waste.

[0005] In addition, when the amount of physiological seawater residue is small, the straw may continuously draw air upward, and the air entering the patient's nasal cavity will cause discomfort to the patient. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-4 The utility model discloses a physiological seawater nasal sprayer, comprising a liquid storage structure 1, the top of the liquid storage structure 1 is movably connected with a liquid extraction structure 3, the liquid storage structure 1 comprises a first shell 101 and a second shell 102, the first shell 101 and the second shell 102 are fixedly connected, the bottom end of the second shell 102 is rotatably connected with a lifting disc 103, the bottom of the first shell 101 is provided with a screw-in notch 109, the lifting disc 103 is located inside the screw-in notch 109, a liquid storage cylinder 107 is movably inserted in the cavity between the first shell 101 and the second shell 102, the top of the lifting disc 103 is overlapped with the bottom of the liquid storage cylinder 107, and the bottom of the inner wall of the liquid storage cylinder 107 is fixedly connected with a built-in slope block 108;

[0022] The liquid extraction structure 3 includes a sealing cover 301, which is movably connected to the sleeve tube composed of the first shell 101 and the second shell 102. A pressing pump 302 and an atomizing nozzle 303 are provided at the top of the sealing cover 301. The bottom end of the sealing cover 301 is fixedly connected to a liquid extraction tube 306, and the bottom end of the liquid extraction tube 306 is located in the gap between the liquid storage tube 107 and the built-in slope block 108.

[0023] By providing the liquid storage structure 1 and the liquid extraction structure 3, and utilizing the built-in slope block 108 provided inside the liquid storage cylinder 107 included in the liquid storage structure 1, physiological seawater can be collected at the gap between the built-in slope block 108 and the liquid storage cylinder 107, and the liquid extraction tube 306 included in the liquid extraction structure 3 can penetrate into the gap between the built-in slope block 108 and the liquid storage cylinder 107, so that each extraction by the liquid extraction tube 306 can extract physiological seawater, thereby avoiding the situation where the liquid level is too low and the straw causes air to enter and exit the nasal cavity, thereby improving the utilization rate of the physiological seawater inside the liquid storage cylinder 107.

[0024] Specifically, the outer side of the liquid storage structure 1 is movably connected to a protective cover 2 via a connecting ring, and the specifications of the protective cover 2 are compatible with the specifications of the sealing cover 301 .

[0025] In this embodiment, the protective cover 2 can cover the sealing cover 301 when the sprayer is idle, so that the pressing pump 302 and the atomizing nozzle 303 above the sealing cover 301 can be protected inside the protective cover 2.

[0026] Specifically, a placement groove 104 is provided on the outer side of the first shell 101 , and a damping spring rod 105 is provided on the inner wall of the placement groove 104 . The top end of the damping spring rod 105 is fixedly connected to a limit bar 106 , and the limit bar 106 is located at the opening of the screw-in notch 109 .

[0027] In this embodiment, the automatic rebound resilience of the damping spring rod 105 can prompt the limit strip 106 to block the opening of the screw-in notch 109, so that the lifting disc 103 cannot be screwed out from the screw-in notch 109, thereby ensuring that the overlapping effect between the lifting disc 103 and the liquid storage cylinder 107 is more stable.

[0028] Specifically, the outer side of the liquid extraction tube 306 is fixedly connected to a splicing strip 304 via a connecting sleeve 305 , and the inner wall of the liquid storage cylinder 107 is provided with a recess adapted to the splicing strip 304 , and the splicing strip 304 is located in the recess.

[0029] In this embodiment, the connecting sleeve 305 can be inserted into the inner wall of the liquid storage cylinder 107, so that when the liquid extraction tube 306 penetrates into the interior of the liquid storage cylinder 107, the distance between the liquid extraction tube 306 and the liquid storage cylinder 107 can be limited, so that the lowest end of the liquid extraction tube 306 can extract physiological seawater located in the gap between the liquid storage cylinder 107 and the built-in slope block 108.

[0030] Specifically, a blocking piece 307 is movably clamped at the bottom end of the liquid extraction tube 306, and the blocking piece 307 is a hollow circular piece.

[0031] In this embodiment, the baffle 307 is used to intercept particles in the physiological seawater to prevent the presence of particles from causing the patient's nasal cavity to be impacted and injured, thereby improving the safety of the nasal sprayer.

[0032] When in use, the protective cover 2 is pulled off to expose the liquid extraction structure 3, and then the pressing pump 302 is pressed down, so that the pressing pump 302 extracts the physiological seawater in the liquid storage cylinder 107 into the atomizing nozzle 303 through the liquid extraction tube 306, and then the physiological seawater is sprayed into the patient's nasal cavity in the form of mist through the atomizing nozzle 303;

[0033] When it is necessary to replenish the liquid storage cylinder 107 with a lower liquid level with seawater, first lift the limit bar 106 so that the limit bar 106 gradually moves upward from the opening where it is screwed into the notch 109, then rotate the lifting disc 103 so that the overlapping state between the lifting disc 103 and the liquid storage cylinder 107 is released, so that the drop opening formed by the first shell 101 and the second shell 102 is exposed, so that the liquid storage cylinder 107 can be separated from the first shell 101 and the second shell 102, and then inject physiological seawater into the liquid storage cylinder 107;

[0034] Then, the liquid storage cylinder 107 after the liquid injection is completed is inserted again between the first shell 101 and the second shell 102, and then the lifting disc 103 is rotated again, so that the lifting disc 103 enters the inside of the screw-in notch 109 again, so that the lifting disc 103 is overlapped with the bottom of the liquid storage cylinder 107 again, and the splicing strip 304 is automatically inserted into the inner wall of the liquid storage cylinder 107 at this time, so that the liquid storage cylinder 107 and the liquid extraction tube 306 are deeply connected;

[0035] Then, the limit bar 106 is loosened, and the automatic rebound of the damping spring rod 105 can cause the limit bar 106 to return to its initial position, so that the limit bar 106 gradually drops, causing the limit bar 106 to block the opening of the screw-in notch 109 again, so that the lifting disc 103 cannot be screwed out of the screw-in notch 109 at this time, thereby ensuring that the overlapping effect between the lifting disc 103 and the liquid storage cylinder 107 is more stable.

[0036] In summary, the physiological seawater nasal sprayer, by providing a liquid storage structure 1 and a liquid extraction structure 3, utilizes the built-in slope block 108 provided inside the liquid storage cylinder 107 included in the liquid storage structure 1, so that the physiological seawater can be collected at the gap between the built-in slope block 108 and the liquid storage cylinder 107, and then cooperates with the liquid extraction tube 306 included in the liquid extraction structure 3 to penetrate into the gap between the built-in slope block 108 and the liquid storage cylinder 107, so that each extraction of the liquid extraction tube 306 can extract the physiological seawater, avoiding the situation that the liquid level is too low and the straw will cause the air to enter and exit the nasal cavity, thereby improving the utilization rate of the physiological seawater inside the liquid storage cylinder 107.
