Development of capacity-controlled ventriculoperitoneal shunt device / 医疗卫生装备

ABSTRACT

Objective To develop a capacity-controlled ventriculoperitoneal shunt device to relieve the symptoms of hydrocephalus patient.Methods The device was composed of head-end shunt tube,middle reservoir and celiac shunt tube.The ends of the reservoir were equipped with one-way valve to drive cerebrospinal fluid to celiac shunt tube in case of the pressure on the reservoir.The capacity-controlled drainage of cerebrospinal fluid was implemented through the times of the pressure.Results The device drained cerebrospinal fluid to relieve the symptoms of hydrocephalus patient,and the complications due to over-or under-drainage were eliminated.Conclusion The device gains advantages in design and easy operation,and is an effective and safe shunt choice for types of hydrocephalus patients.
