Description

LISA administration tube for premature infant

Technical Field

The utility model relates to the technical field of medical appliances, in particular to an LISA (LISA) administration tube for premature infants.

Background

Respiratory distress syndrome is one of the common clinical conditions in premature infants. The 2016 european regulatory guidelines for respiratory distress syndrome considers continuous positive airway pressure in the early stages of premature infants, in combination with Pulmonary Surfactant (PS) replacement therapy, as the "golden combination" for the treatment of respiratory distress syndrome in premature infants. The guidelines mention two main methods of injecting PS through a thin tube using minimally invasive techniques: the LISA method and the miss method. Different from the traditional way of injecting PS through the tracheal intubation, the LISA technology adopts a catheter with a thinner diameter to replace the tracheal intubation to inject PS, and has the technical advantages that the thin tube is placed under a direct-view laryngoscope, so that the operation is simpler; the tubule is placed to replace a tracheal cannula, so that damage to vocal cords and tracheal mucosa is reduced; the PS administration procedure does not require pressure ventilation, and avoids lung injury in premature infants caused by higher pressures or excessive lung inflation during PS administration, so the LISA/miss technique can be considered as part of a lung protective strategy for premature infants.

The traditional LISA technology administration tube does not have the function of adjusting the administration amount, and an injector matched with the traditional LISA technology administration tube is generally operated manually, so that the administration amount of the medicine is difficult to control, the administration amount is excessive due to excessive pushing force, the internal organs of the premature infant are fragile, the absorption capacity is relatively weak, and the excessive administration amount can influence the body of the premature infant. To this end, we propose a premature infant LISA administration tube.
