Description

Umbilical vascular catheter fixing device and method Technical Field The invention relates to the technical field of umbilical vascular catheter treatment, in particular to an umbilical vascular catheter fixing device and an umbilical vascular catheter fixing method. Background Currently, umbilical vascular catheters are widely used for infusion, blood sampling and vital sign monitoring in neonatal intensive care units. However, due to tender skin, frequent activities, etc., the umbilical vascular catheter is easy to fall off or shift, which brings inconvenience to medical staff and may even endanger the life safety of the neonate. Therefore, how to effectively fix an umbilical vascular tube is a problem to be solved. The traditional umbilical vascular catheter fixing method mainly comprises the steps of fixing by using a medical adhesive tape, using a special umbilical clamp and winding by using an elastic bandage, wherein although the fixing purpose can be met to a certain extent, a plurality of problems still exist after the umbilical vascular catheter fixing method is used, the medical adhesive tape is not firm and is easily loosened due to the influence of sweat, sebum and other factors, skin allergy of a neonate can be caused after long-time use, the special umbilical clamp is complex in operation, a professional is required to adjust, the cost is high, the elastic bandage is used for winding the fixing force is insufficient, the fixing force is easily loosened along with the activities of the neonate, the requirement on fixing the umbilical vascular catheter is higher and higher along with the progress of technology, the method can only singly solve part of problems, the problems of unfitness in fixing, complex operation, high cost and the like can not be comprehensively solved, and clinical requirements can not be met, and the defects are more prominent particularly in the neonate intensive care environment.
