Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a pressurized ultrasonic nasal nebulizer. Background Technology

[0002] A nasal nebulizer is a medical device that transforms liquid medications into tiny particles, which are inhaled through the nostrils and act directly on the nasal cavity and upper respiratory tract. This method of drug delivery can effectively treat various nasal conditions, such as allergic rhinitis and chronic sinusitis, and can reduce systemic side effects because the medication is primarily concentrated in a localized area.

[0003] Nasal nebulizers typically use compressed air or ultrasonic technology to generate fine droplets that can be inhaled through the nostrils, reaching deep into the nasal cavity and even the sinuses. This method allows for more even distribution of medication within the nasal cavity, improving drug efficacy and absorption.

[0004] However, existing ultrasonic nasal nebulizers have the following shortcomings in practical use: due to insufficient nebulizing gas pressure, they cannot effectively deliver medication droplets to the designated area for patients with nasal congestion. Therefore, to address this deficiency, the pressurized ultrasonic nasal nebulizer of this application is proposed. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a pressurized ultrasonic nasal nebulizer that can increase atomization pressure to ensure that the liquid medicine can be delivered to the designated location.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A pressurized ultrasonic nasal nebulizer includes:

[0008] An atomizing assembly includes an atomizing shell, an atomizing plate, and an air pump. The atomizing shell has a liquid storage chamber with an atomizing hole at the bottom and an air outlet at the top. The atomizing shell also has a pressurizing through-hole, one end of which communicates with the liquid storage chamber, and the other end extends outside the atomizing shell. The atomizing plate is disposed within the atomizing hole. The positive pressure end of the air pump is connected to the end of the pressurizing through-hole furthest from the liquid storage chamber.

[0009] Optionally, the atomizing shell includes a lower shell and a retaining shell, the atomizing hole is located at the bottom of the lower shell, the air outlet is located at the top of the retaining shell, and the retaining shell is fastened to the lower shell so that the lower shell and the retaining shell together form the liquid storage chamber.

[0010] Optionally, the snap-fit ​​shell is engaged with the lower shell.

[0011] Optionally, the pressurization through hole is located inside the lower shell, and the pressurization through hole extends from one end of the liquid storage chamber to the snap shell.

[0012] Optionally, a soft sleeve is also provided on the top of the casing to cover the air outlet.

[0013] Optionally, the outer diameter of the soft sleeve gradually decreases in the direction away from the snap shell.

[0014] Optionally, the atomizing shell further includes a cover, which is disposed on the inner side wall of the shell and is located between the air outlet and the atomizing hole.

[0015] Optionally, the pressurized ultrasonic nasal nebulizer further includes a bottom shell, which is disposed at the bottom of the lower shell. A battery and a circuit board are disposed inside the bottom shell, and the battery, the atomizing plate, and the air pump are all electrically connected to the circuit board.

[0016] Optionally, the bottom shell includes a housing and an end cap, the end cap being fastened to the bottom of the housing, the lower shell being disposed at the top of the housing, and the battery and the circuit board being located inside the end cap.

[0017] Optionally, the pressurized ultrasonic nasal nebulizer further includes a cover, which is fastened to one end of the housing near the nebulizing shell, so that the nebulizing shell is located inside the cover.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] This utility model discloses a pressurized ultrasonic nasal nebulizer, comprising a nebulizing component, which includes a nebulizing shell, a nebulizing plate, and an air pump. The nebulizing shell has a liquid storage chamber with a nebulizing hole at the bottom and an air outlet at the top. A pressurizing through-hole is also provided within the nebulizing shell, with one end connected to the liquid storage chamber and the other end extending outside the nebulizing shell. The nebulizing plate is disposed within the nebulizing hole. The positive pressure end of the air pump is connected to the end of the pressurizing through-hole away from the liquid storage chamber. Thus, under the pressurizing action of the air pump, the atomized droplets from the nebulizing plate are discharged from the air outlet with a certain pressure.

[0028] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings illustrate preferred embodiments of this utility model.

[0029] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0032] like Figure 1 and Figure 2 As shown, a pressurized ultrasonic nasal nebulizer 10 includes an atomizing component 100, which includes an atomizing shell 110, an atomizing plate 120, and an air pump 130. The atomizing shell 110 has a liquid storage chamber 111, an atomizing hole 1121 at the bottom of the liquid storage chamber 111, and an air outlet 1131 at the top of the liquid storage chamber 111. The atomizing shell 110 also has a pressurizing through hole 1122, one end of which is connected to the liquid storage chamber 111, and the other end of which extends to the outside of the atomizing shell 110. The atomizing plate 120 is disposed in the atomizing hole 1121. The positive pressure end of the air pump 130 is connected to the end of the pressurizing through hole 1122 away from the liquid storage chamber 111.

[0033] It should be noted that the atomizing shell 110 has a liquid storage chamber 111 for easy liquid filling. An atomizing hole 1121 and an air outlet 1131 are respectively formed at the bottom and top of the liquid storage chamber 111. An atomizing plate 120 is installed within the atomizing hole 1121, and the atomizing plate 120 is used to contact the liquid in the liquid storage chamber 111 to atomize the liquid. Furthermore, the atomizing shell 110 also has a pressurizing through hole 1122. One end of the pressurizing through hole 1122 extends into the liquid storage chamber 111 near the air outlet 1131, while the other end extends to the outside of the atomizing shell 110. The positive pressure end of the air pump 130 is connected to the end of the pressurizing through hole 1122 located outside the atomizing shell 110. Thus, under the pressurizing effect of the air pump 130, the atomized droplets from the nebulizer 120 are discharged from the air outlet 1131 with a certain pressure. Therefore, compared to existing nebulizers that only have the function of atomization, this application can effectively increase the pressure of the atomized droplets on the basis of atomization, and can reliably deliver the atomized droplets to the lesion site for patients with nasal congestion, etc.

[0034] like Figures 1 to 4 As shown, in one embodiment, the atomizing shell 110 includes a lower shell 112 and a snap-on shell 113. The atomizing hole 1121 is located at the bottom of the lower shell 112, and the air outlet 1131 is located at the top of the snap-on shell 113. The snap-on shell 113 is snapped onto the lower shell 112 so that the lower shell 112 and the snap-on shell 113 together form a liquid storage chamber 111.

[0035] It should be noted that the snap-on housing 113 is snapped into the lower housing 112, which makes it easy to remove the snap-on housing 113 from the lower housing 112 and pour the liquid into the liquid storage chamber 111.

[0036] like Figure 3 and Figure 4 As shown, in one embodiment, the snap-on shell 113 is engaged with the lower shell 112.

[0037] Specifically, two opposing protrusions 1132 are provided on the outer side wall of the snap-on housing 113, and two opposing locking holes 1123 are provided on the lower housing 112. Furthermore, opposing clearance grooves 1124 are also provided on the inner side wall of the lower housing 112, with each of the two clearance grooves 1124 communicating with one of the two locking holes 1123. Thus, when the snap-on housing 113 is inserted into the lower housing 112, the protrusions 1132 slide in along the clearance grooves 1124. When the snap-on housing 113 is inserted to the designated position on the lower housing 112, rotating the snap-on housing 113 causes the protrusions 1132 to engage with the locking holes 1123, thereby securing the snap-on housing 113 to the lower housing 112.

[0038] In one embodiment, the pressurization through hole 1122 is located inside the lower shell 112, and one end of the pressurization through hole 1122 located in the liquid storage chamber 111 extends to the snap shell 113.

[0039] It should be noted that, in order to prevent the liquid in the storage chamber 111 from flowing out of the pressurization through-hole 1122, the pressurization through-hole 1122 is configured to extend to the housing 113. In this way, it can be ensured that the air pump 130 pressurizes the atomized liquid in the storage chamber 111 through the pressurization through-hole 1122, while preventing the liquid from flowing out through the pressurization through-hole 1122.

[0040] like Figure 1 As shown, in one embodiment, a soft sleeve 114 is also provided on the top of the casing 113, and the soft sleeve 114 is used to cover the air vent 1131.

[0041] It should be noted that, since the cover 113 is made of rigid plastic, a soft sleeve 114 is fitted over the air outlet 1131 to prevent direct hard contact between the air outlet 1131 and the patient. This allows the soft sleeve 114 to contact the inner wall of the user's nostril. In one embodiment, the soft sleeve 114 is made of silicone.

[0042] like Figure 2 As shown, in one embodiment, the outer diameter of the soft sleeve 114 gradually decreases in the direction away from the snap shell 113. Thus, the soft sleeve 114 has a certain curvature, allowing for better contact with the inner wall of the patient's nostril.

[0043] like Figure 2 and Figure 5 As shown, in one embodiment, the atomizing shell 110 further includes a cover 115, which is disposed on the inner side wall of the snap shell 113 and is located between the air outlet 1131 and the atomizing hole 1121.

[0044] It should be noted that since the atomizing hole 1121 is aligned with the air outlet 1131, it means that the atomizing plate 120 is also aligned with the air outlet 1131. To prevent the liquid in the liquid storage chamber 111 from being agitated by the atomizing plate 120 and directly rushing out of the air outlet 1131 when the atomizing plate 120 is working, a baffle 115 is installed on the inner side wall of the housing 113, so that the baffle 115 blocks the air outlet 1131 and the atomizing hole 1121.

[0045] like Figure 1 and Figure 2 As shown, in one embodiment, the pressurized ultrasonic nasal atomizer 10 further includes a bottom shell 210, which is disposed at the bottom of the lower shell 112. A battery and a circuit board 220 are disposed inside the bottom shell 210. The battery, atomizing plate 120, and air pump 130 are all electrically connected to the circuit board 220.

[0046] It should be noted that the atomizer of this application can be used directly by plugging in a power supply, or it can be used by charging. Specifically, in the charging method, a bottom shell 210 is installed at the bottom of the lower shell 112, and a battery and circuit board 220 are installed inside the bottom shell 210. The battery and circuit board 220 are connected by wires, and the circuit board 220 is connected to the air pump 130 and the atomizing plate 120 by wires. In this way, the user can hold the atomizer of this application for use.

[0047] like Figure 2 As shown, in one embodiment, the bottom shell 210 includes a shell 211 and an end cap 212. The end cap 212 is fastened to the bottom of the shell 211, and the lower shell 112 is disposed on the top of the shell 211. The battery and circuit board 220 are both located inside the end cap 212.

[0048] It should be noted that, to facilitate the installation of the battery and circuit board 220, the bottom shell 210 is designed with a detachable structure between the housing 211 and the end cap 212. Specifically, the end cap 212 is installed at the bottom of the housing 211, and the lower shell 112 is installed at the top of the housing 211. Both the battery and circuit board 220 are mounted on the end cap 212. For example, the end cap 212 and the housing 211 are secured together by screws.

[0049] like Figure 1 As shown, in one embodiment, the pressurized ultrasonic nasal nebulizer 10 further includes a cover 240, which is fastened to one end of the housing 211 near the atomizing shell 110 so that the atomizing shell 110 is located inside the cover 240.

[0050] Thus, when the atomizer is not in use, the cover 240 is fastened to the housing 211 to protect the atomizer housing 110, the air outlet 1131, and the soft sleeve 114.

[0051] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in this utility model can be understood to include, but is not limited to, locking and fixing with screws / bolts, and welding. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
