Pressure-adjustable back-knocking expectorator for infants and young children

technical field

The utility model relates to a pressure-adjustable back-knocking phlegm-expelling device for infants and young children.

Background technique

Respiratory tract management is an important part of the treatment of respiratory diseases, and timely expectoration is the fundamental guarantee for effective respiratory tract management. Once the respiratory tract is infected, inflammatory edema will occur in the bronchi, resulting in thickening of the tube wall and thinning of the lumen. At the same time, a large amount of sputum will be secreted, and the accumulation of sputum will cause inflammation to continue to develop, eventually leading to narrowing and obstruction of the airway, resulting in respiratory resistance. Increase, forming wheeze. Long-term inflammation will seriously obstruct the airway, causing the cilia on the trachea wall responsible for expectoration to fall down and fall off, making it very difficult to expel sputum, resulting in continuous decline in lung function. Timely expulsion of sputum can ensure smooth airway, improve ventilation and ventilation function, reduce sputum clogging, bacterial colonization, and prevent lung infection and atelectasis.

Generally, normal adults can expel sputum through coughing. However, due to immature respiratory system, infants and young children have narrow airways, poor cough reflex, poor airway ciliary movement and poor immune function, infants and young children are more likely to have sputum blocking the respiratory tract. Sputum expectoration has become one of the routine operations in the treatment of critically ill children.

For infants with poor cough reflex, long-term bed rest, unconsciousness, and thick sputum, chest physical therapy can only be used to promote sputum discharge. Chest physical therapy includes back percussion, tremors, postural drainage, and effective coughing. Knocking the back of the chest is the most commonly used and effective way to expel phlegm. The airflow vibration generated by knocking and rapid hand vibration is transmitted to the airway through the chest wall, so that the secretions attached to the lungs and bronchus fall off, and pass through the body position. Drainage, so that secretions reach the bronchioles, or excreted by stimulating cough or swallowed and excreted with feces. Its mechanism: the vertical force of tapping can relax and crush the shedding sticky secretions, and the horizontal force can promote the directional movement of the secretions. At the same time, percussion can stimulate the secretion of plasma cells and dilute sputum; stimulate nerve endings, strengthen the peristalsis of cilia, and expel sputum; stimulate coughing, so that children can cough up sputum; The permeability of the respiratory tract is enhanced, and the absorption of secretions is increased; the vibration is transmitted to the lung lobes through the chest cavity, causing the sputum in the lung lobes to loosen and fall off.

In clinical work, the traditional method of manually tapping the back to expel sputum has weak penetration, the action site is superficial, and the force cannot be effectively transmitted to the lesion. In addition, manual tapping is labor-intensive and the operator is prone to fatigue. Rhythm, strength, can not achieve the purpose of more durable and effective expectoration. Moreover, the comfort of traditional manual back tapping is poor, and it is difficult for children to cooperate. For the medical staff in the intensive care unit for children, their work intensity is high. In order to achieve effective management of children with severe respiratory diseases, improve the success rate of rescue, and "doubling the result with half the effort" in the treatment process, effective expectoration equipment and or methods are urgently needed. At present, the scope of application of the sputum expectoration machine that has been launched clinically is limited: the child is older than 2 years old, cannot be dedicated to a special person, is not conducive to the prevention and control of cross-infection, and the fees are high. It is difficult to become a routine method for long-term and frequent sputum removal work. .
