Background technique

The ventilator is a vital medical equipment that can prevent and treat respiratory failure, reduce complications, and save and extend the patient's life. In modern clinical medicine, as an effective means to artificially replace the spontaneous ventilation function, it has been widely used in respiratory failure caused by various causes, anesthesia respiratory management during major surgery, respiratory support treatment and emergency resuscitation.

When the ventilator performs oxygen supply and respiration, the breathing mask is usually fixed on the face of the newborn through tape, and then the oxygen supply tube of the ventilator is used to supply oxygen to the inside of the breathing mask, so that the newborn can absorb enough oxygen. , but newborns sometimes have excessive sputum due to various factors. Even if a large amount of oxygen is supplied in the breathing mask, it will affect the newborn's normal breathing.

Since babies are still relatively young, the phlegm in the body generally cannot be discharged on their own. In clinical practice, a negative pressure suction device is generally used. Put one end of the sputum suction tube into the child's mouth or nasal cavity to aspirate phlegm. However, at this time, it is necessary to It is inconvenient to remove the respiratory mask if the newborn has difficulty breathing. At the same time, the newborn's oral cavity or nasal cavity is relatively fragile. If the suction tube moves to a large extent, it may cause harm to the newborn. Therefore, we have proposed the newborn Ventilator suction device for pediatric use.
