Cerebrospinal fluid dynamic precise regulation and control nursing device

Abstract

The invention belongs to the technical field of medical equipment, and provides a cerebrospinal fluid dynamic precise regulation and control nursing device. The device comprises a resonant pressure assembly, wherein the resonant pressure assembly comprises an elastic corrugated pipe and a resonator; one end of the elastic corrugated pipe is communicated with the brain of a patient, the resonator is mounted at the elastic corrugated pipe, and the resonator resonates with the heartbeat of the patient and amplifies pressure waves; the self-balancing valve is mounted on the resonance type pressure assembly; the self-balancing valve comprises a valve body and a conical balance weight ball valve, and the conical balance weight ball valve is installed in the valve body in a sliding mode. One end of the valve body is connected with the elastic corrugated pipe; one end of the drainage assembly is mounted on the self-balancing valve; the drainage assembly comprises a Venturi tube and an elastic membrane; one end of the Venturi tube is communicated with the other end of the valve body; the elastic membrane is mounted at a throat pipe of the venturi tube, and the other end of the venturi tube is communicated with an external collecting bag; the elastic membrane comprises a bimetallic strip; the bimetallic strip is a temperature sensing metal sheet and deforms after being heated.
