Description

Technical Field

[0001] This utility model relates to a nasal aspirator, and more particularly to an anti-backflow nasal aspirator. Background Technology

[0002] Nasal aspirators are typically used by infants, the elderly, or people with serious illnesses. These groups usually cannot expel nasal secretions on their own. Excessive nasal secretions can block the nostrils, causing breathing difficulties and nasal ulcers. Furthermore, nasal secretions flowing back into the lungs due to blocked nostrils can cause lung inflammation. Therefore, nasal aspirators were invented to clear nasal secretions. As the number of infants, the elderly, and people with serious illnesses increases, the use of nasal aspirators becomes increasingly important.

[0003] With the rapid development of the medical industry, the use of medical devices is increasing, and consequently, the use of nasal aspirators is also increasing. As a result, the requirements for nasal aspirators are also increasing. Existing nasal aspirators usually do not have an anti-backflow function, which can easily cause discomfort to users. Utility Model Content

[0004] To address the aforementioned problems, this utility model aims to provide an anti-backflow nasal aspirator, which can effectively remove foreign objects from the nasal cavity while preventing the dirt sucked out by the aspirator from flowing back into the nasal cavity.

[0005] The present invention relates to an anti-backflow nasal aspirator, comprising a main body, wherein a channel is provided inside the main body to penetrate the front and rear ends, a nasal aspirator tip is connected to the front end of the main body, the nasal aspirator tip has an axial through hole, and a soft rubber suction ball is connected to the rear end of the main body. The aspirator tip is characterized by having a connecting sleeve connected to its rear end, the connecting sleeve having an axial through hole, a first soft rubber pad at the rear end of the connecting sleeve, a first lateral channel and a second lateral channel on the side wall of the main body, a second soft rubber pad on the outer side of the first lateral channel, and a third soft rubber pad on the outer side of the second lateral channel; the first and second soft rubber pads are provided with annular cuts and respectively cover and adhere to the surface of the axial through hole of the connecting sleeve and the surface of the first lateral channel, and the third soft rubber pad seals the second lateral channel. When the soft rubber suction ball is squeezed inward, the first soft rubber pad blocks the axial through hole of the sealing connecting sleeve, the second soft rubber pad flips outward and opens the first lateral channel, and the third soft rubber pad bulges outward to achieve outward exhaust. When the soft rubber suction ball rebounds and expands after being released, the first soft rubber pad flips backward to open the axial through hole of the connecting sleeve, the second soft rubber pad blocks the first lateral channel, and the third soft rubber pad is recessed inward, thus sucking out the secretions in the nasal cavity.

[0006] Preferably, a first soft rubber sleeve is fitted onto the rear end face of the connecting sleeve, and an annular slit is provided on the end face of the first soft rubber sleeve, forming a first soft rubber pad in the area enclosed within the annular slit.

[0007] Preferably, a second soft rubber sleeve is fitted onto the outer wall of the main body. The end face of the second soft rubber sleeve has an annular cut. The area enclosed by the annular cut forms a second soft rubber pad, and another area of ​​the second soft rubber sleeve forms a third soft rubber pad.

[0008] Preferably, the outer rear side of the main body is provided with an annular groove, the rear part of the annular groove is tapered from front to back, and the soft rubber suction ball is engaged and connected in the annular groove with an interference fit to achieve a seal.

[0009] Preferably, the thickness of the third soft rubber pad is 0.3-0.8 mm.

[0010] This invention can effectively remove foreign objects from the nasal cavity, while preventing the dirt sucked out by the nasal aspirator from entering the nasal cavity in reverse. Attached Figure Description

Detailed Implementation

[0012] The present invention will now be described in further detail with reference to the accompanying drawings.

[0013] like Figures 1 to 4As shown, this utility model provides an anti-backflow nasal aspirator, including a main body 1. The main body 1 has a channel extending through its front and rear ends. A nasal aspirator 2 is connected to the front end of the main body 1, and the nasal aspirator 2 has an axial through hole. A soft rubber suction ball 3 is connected to the rear end of the main body 1. A connecting sleeve 4 is connected to the rear end of the nasal aspirator 2, and the connecting sleeve 4 has an axial through hole. A first soft rubber pad 5 is provided at the rear end of the connecting sleeve 4. A first lateral channel 11 and a second lateral channel 12 are provided on the side wall of the main body 1. A second soft rubber pad 6 is provided on the outside of the first lateral channel 11, and a third soft rubber pad 7 is provided on the outside of the second lateral channel 12. The first soft rubber pad 5 and the second soft rubber pad 6 are provided with annular cuts and respectively cover and adhere to the surface of the axial through hole of the connecting sleeve 4 and the surface of the first lateral channel 11. The third soft rubber pad 7 seals the second lateral channel 12. When the soft rubber suction ball 3 is squeezed inward, the first soft rubber pad 5 blocks the axial through hole of the sealing connecting sleeve 4, the second soft rubber pad 6 flips outward and opens the first lateral channel 11, and the third soft rubber pad 7 bulges outward to realize the exhaust of air. When the soft rubber suction ball 3 rebounds and expands after being released, the first soft rubber pad 5 flips backward to open the axial through hole of the connecting sleeve 4, the second soft rubber pad 6 blocks the first lateral channel 11, and the third soft rubber pad 7 is recessed inward to suction out the secretions in the nasal cavity.

[0014] In the above scheme, the rear end face of the connecting sleeve 4 is fitted with a first soft rubber sleeve 8, and the end face of the first soft rubber sleeve 8 is provided with an annular cut, and the area enclosed within the annular cut forms a first soft rubber pad 5.

[0015] In addition, a second soft rubber sleeve 9 is sleeved and connected to the outer wall of the main body 1. The end face of the second soft rubber sleeve 9 is provided with an annular cut. The area enclosed by the annular cut forms a second soft rubber pad 6, and another area of ​​the second soft rubber sleeve 9 forms a third soft rubber pad 7.

[0016] In addition, an annular groove 13 is provided on the outer rear side of the main body 1. The rear part of the annular groove 13 is tapered from front to back. The soft rubber suction ball 3 is engaged and connected in the annular groove 13 with an interference fit to achieve a seal.

[0017] Furthermore, the thickness of the third soft rubber pad 7 is 0.3-0.8 mm.

[0018] This invention achieves air intake and exhaust through the unidirectional sealing of the first soft rubber pad 5 and the second soft rubber pad 6, combined with the squeezing or expansion of the soft rubber suction ball 3. At the same time, the outward protrusion and inward depression of the third soft rubber pad 7 can serve as a direct observation point to ensure that there is no internal air leakage.

[0019] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
