Description

A medical nasal aspirator based on cleaning the inside of baby's nasal cavity

technical field

The invention relates to the field of medical technology, in particular to a medical nasal aspirator based on cleaning the inside of a baby's nasal cavity.

Background technique

Nasal congestion is often caused by scabs of secretions during the growth process of babies, and babies do not actively blow their noses, which makes it difficult to clear the secretions and scabs. At present, in order to solve this problem, there are mainly two solutions. One of them requires a nasal aspirator. The nasal aspirator mainly uses negative suction to suck inside the nostrils. Moreover, this method is difficult to suck out some dry and hard secretions scabs. For dry and hard scabs, there are two current solutions. One is to use tweezers to pinch them out when the baby is asleep. The inside of the nasal cavity is relatively fragile, and the dry and hard scabs are attached to the nasal mucosa, which can easily damage the nasal mucosa, cause bleeding or even nasal adhesion, and cause harm to the baby. Another way is to squeeze breast milk or water inside the nasal cavity to soften the nasal cavity. feces, but this method may choke the baby no matter when the baby is sleeping or awake, causing discomfort to the baby. When the general nasal aspirator removes foreign objects inside the baby's nasal cavity, it is responsible for dry and hard secretions. The way of suction is difficult to suck out, and the tweezers are easy to cause internal bleeding in the nasal cavity, and the dripping water enters the internal nasal cavity to soften the booger and easily choke the baby. Therefore, a medical nasal aspirator based on the internal cleaning of the nasal cavity of the baby is needed.

(3) Beneficial effects

(1) The present invention sets up a fine-tuning cleaning mechanism and utilizes the negative suction wind force to cause the fine-tuning spring to vibrate slightly. The slightly jittering fine-tuning spring can slowly control the flow of a small amount of liquid, and a small amount of liquid comes into contact with booger along the fine-tuning spring. And flow into the nasal cavity to moisten the nasal cavity and soften the booger.

(2) By setting the secretion attachment mechanism in the present invention, when picking boogers, fine-tuning the compression of the vibrating spring will cause the movable ball at the bend to flip over, and the flipped miniature movable ball will use the hooks on its surface to hold Some fluid boogers are coiled, which is convenient for clamping, and when the fine-tuning spring is compressed, the suction generated by the suction groove will generate an adsorption force on the gap of the fine-tuning spring that gradually becomes tubular, which can absorb the nasal mucus. Compared with the prior art, it can prevent the strong nasal mucus from falling off during the clamping process.

(3) The present invention can repeatedly compress and fine-tune the vibrating spring when picking up boogers, without adjusting the position of the nasal aspirator body. Spring, the fine-tuning vibrating spring is squeezed by the inclined diversion groove and bends to the inside to produce a slight dragging effect, which can slightly drag the booger, repeating this can loosen the booger and facilitate the removal of the booger, which is different from the existing manual Compared with the control, it is convenient to control, there will be no force control error, and there is no need to repeatedly increase the position of the entire nasal aspirator, which is convenient to operate and safer.

(4) According to the booger characteristics inside the baby's nasal cavity, the present invention designs a special and conveniently manipulated structure, which can not only avoid damage to the baby's nasal cavity, but also quickly remove the secretions, thus effectively solving the general nasal suction problem. When the device is used to remove foreign objects in the baby's nasal cavity, for dry and hard secretions, negative suction is difficult to suck out, and tweezers are easy to cause internal bleeding in the nasal cavity, dripping water into the nasal cavity to soften the booger is easy to choke the baby .
