Description

Technical Field

[0001] This utility model relates to the field of suction equipment technology, and more specifically, to a nasal aspirator. Background Technology

[0002] When newborns, infants, or children without nasal control have secretions, these secretions not only cause airway obstruction and difficulty breathing, but are also watery and can lead to nasal skin ulceration due to prolonged accumulation. Furthermore, the watery secretions can flow back into the lungs due to nasal blockage, causing pneumonia. Additionally, nasal secretions are easily ingested by newborns, infants, or children without nasal control, leading to bacterial infections. Therefore, it is essential to quickly and thoroughly remove nasal secretions and clear the airway. A nasal aspirator is an instrument used to suction nasal secretions, typically used when infants' noses are congested and secretions cannot be expelled. However, most nasal aspirators on the market are oral aspirators, relying on adults to suck the baby's nasal mucus with their mouths. This is very unhygienic and significantly increases the risk of infection during the suction process. Moreover, adults have limited lung capacity and cannot generate a sustained and large negative pressure during oral suction. Utility Model Content

Detailed Implementation

[0031] To ensure a clear and complete description of the technical solutions in the embodiments of this utility model below, in conjunction with the accompanying drawings, it is evident that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0033] Please see Figure 1-9 The present invention provides a nasal aspirator, comprising: a suction head mechanism for insertion into the nasal cavity and a negative pressure mechanism 400 for driving the suction head mechanism to aspirate nasal secretions into the suction head mechanism; the suction head mechanism includes: a suction head body 100 with a suction port, and a liquid storage tank 200 detachably connected to the suction head body 100, wherein a secretion storage cavity for storing nasal secretions is formed between the suction head body 100 and the liquid storage tank 200; the side of the suction head body 100 or the liquid storage tank 200 is connected to the negative pressure mechanism 400 through a conduit 300.

[0034] This utility model discloses a nasal aspirator. When suctioning secretions from the nasal cavity, the suction head body 100 of the suction head mechanism is first placed into the nasal cavity. Then, the negative pressure mechanism 400 is controlled to generate negative pressure, thereby cooperating with the catheter 300, the suction head body 100, and the liquid reservoir 200 to draw the secretions from the nasal cavity into the secretion storage cavity between the suction head body 100 and the liquid reservoir 200. Compared with the oral suction nasal aspirator in the prior art, it is cleaner and more hygienic, and the suction effect is stable. Furthermore, the suction head body 100 and the liquid reservoir 200 of the suction head mechanism are detachably connected, which can be a threaded connection. The connection has good stability and is also easy to disassemble, thereby cleaning the secretions in the secretion storage cavity formed by the suction head body 100 and the liquid reservoir 200.

[0035] The negative pressure mechanism 400 includes: a negative pressure pump body 401, a pump cover 402, a multi-layer integrated piston 403, and a piston handle 404; one end of the negative pressure pump body 401 is provided with an air inlet for connecting the conduit 300, and the other end of the negative pressure pump body 401 is connected to the pump cover 402; the multi-layer integrated piston 403, which is sealed and fixed on the pump cover 402, is inserted into the negative pressure pump body 401; the piston handle 404 is slidably mounted on the pump cover 402 in the middle, and one end of the piston handle 404 inserted into the negative pressure pump body 401 is connected to the multi-layer integrated piston 403.

[0036] The negative pressure mechanism 400 is used to generate negative pressure. During operation, the negative pressure pump body 401 is held and the piston handle 404 is pulled outward. The piston handle 404 can drive the multi-layer integrated piston 403 to fold and retract, forming a negative pressure chamber between the multi-layer integrated piston 403 and the negative pressure pump body 401. This, in conjunction with the cannula 300, draws air out of the suction head body 100 and the liquid reservoir 200, creating negative pressure in the secretion storage cavity formed between the suction head body 100 and the liquid reservoir 200. This allows nasal secretions to be drawn out through the suction port of the suction head body 100. The piston handle 400... There is a gap between 04 and the pump cover 402 to facilitate the discharge of gas when the multi-layer integrated piston 403 contracts. The air inlet is equipped with a one-way valve to allow gas to flow unidirectionally from the conduit 300 into the negative pressure pump body 401 and prevent gas backflow. After pulling the piston handle 404 to complete one suction cycle, pushing the piston handle 404 controls the multi-layer integrated piston 403 to reset and unfold, and the gas between the multi-layer integrated piston 403 and the negative pressure pump body 401 is discharged through the exhaust pipe with a one-way valve on the negative pressure pump body 401 or the multi-layer integrated piston 403, so as to facilitate the generation of negative pressure for suction again.

[0037] In the nasal aspirator provided by this utility model, the multi-layer integrated piston 403 includes: a ring structure 1 having two or more ring layers, one end of the ring structure 1 being provided with a receiving end plate structure 2 for connecting the piston handle 404, and the other end of the ring structure 1 being provided with an abutment sealing structure 3 for sealing the connection to the pump cover 402.

[0038] In this nasal aspirator, the multi-layer integrated piston 403 has two or more annular layers on its annular structure 1. When the multi-layer integrated piston 403 is pressed, folded, or expanded by the piston handle 404, bending damage to the multi-layer integrated piston 403 is reduced. Furthermore, the volume of the multi-layer integrated piston 403 can be effectively reduced during folding, ensuring a negative pressure suction effect and facilitating the removal of more nasal mucus. At the other end of the annular structure 1, there is an abutment sealing structure 3 for sealing the connection to the pump cover 402. The two are in a fixed, sealed state, which is not easily worn, thus improving service life while ensuring suction effect. At one end of the annular structure 1, there is a connecting end plate structure 2 for connecting the piston handle 404, making it easy to connect or disconnect from the piston handle 404. The flexible design of the annular structure 1 ensures that the piston can effectively generate and maintain negative pressure during operation. The stable negative pressure effect helps to more effectively remove liquid and foreign objects from the nasal cavity, improving the effectiveness of the nasal aspirator.

[0039] The annular structure 1 is made of silicone or rubber. Silicone or rubber materials possess excellent elasticity and flexibility, allowing the annular structure 1 to adapt to various complex operating environments. This makes the annular structure 1 less prone to wear during use, extending the piston's service life and reducing the frequency of maintenance and replacement.

[0040] An acute angle is formed between two adjacent annular layers in the annular structure 1. The acute angle design increases the piston's folding and unfolding capabilities, improves its flexibility and adaptability, and helps maintain the stability of the annular structure. The acute angle design can prevent unnecessary deformation or displacement of the annular structure 1 during use, ensuring that the piston maintains a stable structure during operation and improving the reliability and performance of the nasal aspirator.

[0041] The receiving end plate structure 2 includes a receiving end plate 201, the outer ring of which is connected to the annular layer structure 1. The receiving end plate 201 is made of rigid plastic. A circular connection hole 202 is provided at the center of the receiving end plate 201 for connection with the piston handle 404, and a rubber sealing ring is bonded inside the circular connection hole 202. The rigid plastic construction of the receiving end plate 201 provides high structural strength and stability, helping to ensure that the piston is not easily deformed or damaged during use, thus improving the overall reliability and durability of the nasal aspirator. The circular connection hole 202 at the center of the receiving end plate 201 allows for easy installation and removal of the piston handle 404, facilitating cleaning and maintenance and improving ease of use. The rubber sealing ring bonded inside the circular connection hole 202 provides good sealing performance, preventing air leakage and ensuring the negative pressure effect and efficiency of the nasal aspirator. The use of the sealing ring also reduces the risk of performance degradation due to loose connections.

[0042] The contact sealing structure 3 includes: a contact ring 301 for sealing against the pump cover 402, the contact ring 301 being fixed to one end of the cylindrical tube 302, and the other end of the cylindrical tube 302 being fixed to the ring layer structure 1. The contact ring 301 and the pump cover 402 can be bonded together to ensure a good sealing contact effect and prevent loosening.

[0043] The outer diameter of the contact ring 301 is larger than the outer diameter of the cylindrical tube 302, the inner diameter of the cylindrical tube 302 is larger than the outer diameter of the mounting end plate 201, the maximum outer diameter of the annular structure 1 is smaller than the outer diameter of the cylindrical tube 302, and the minimum inner diameter of the annular structure 1 is smaller than the inner diameter of the cylindrical tube 302. The design of the above structure is beneficial to improving the negative pressure suction effect and ensuring the stability of the movement of the annular structure 1.

[0044] The end plate structure 2, the ring layer structure 1, and the contact sealing structure 3 are formed as a single piece.

[0045] The nasal aspirator further includes: a curved rod 4, the inner ends of multiple curved rods 4 being uniformly and fixedly connected around the side of the receiving end plate structure 2 away from the ring layer structure 1, the outer ends of multiple curved rods 4 being uniformly and fixedly connected around the inner ring surface of the guide ring 5, and the outer ring surface of the guide ring 5 being slidably fitted on the inner wall of the negative pressure pump body 401.

[0046] The inner ends of multiple bent rods 4 are evenly and fixedly connected to the side of the receiving end plate structure 2 away from the annular layer structure 1. The outer ends of multiple bent rods 4 are evenly and fixedly connected to the inner ring surface of the guide ring 5. This helps to enhance the stability of the movement of the annular layer structure 1 and the receiving end plate structure 2, and prevents unnecessary deformation or loosening of the annular layer structure 1 and the receiving end plate structure 2 during the push-pull control by the piston handle 404. The outer ring surface of the guide ring 5 slides and fits on the inner wall of the negative pressure pump body 401. The design of the guide ring 5 not only plays a stable guiding role, but also effectively scrapes the dirt on the inner wall of the negative pressure pump body 401 during use, removing the liquid or dirt attached to the inner wall of the negative pressure pump body 401, ensuring the fit and service life of the multi-layer integrated piston 403 structure and the negative pressure pump body 401.
