The XL200SC Sinapi Chest Drain is specifically used for infants and children undergoing cardiac surgery. It is fitted with a tube roller and high negativity vent. The tube roller facilitates stripping of the tubing to remove clots maintaining patency of tubing. Stripping, however, can generate transient high levels of negative intra-thoracic pressure which can be detrimental to tissues and areas being drained. The high negativity vent, positioned in the connector of this Sinapi chest drain, ensures that excessively high negative pressures cannot be achieved during this procedure. Using the Sinapi tube roller and high negativity vent therefore results in effective drainage and a reduction in blocked chest catheters without risk to the patient.
