Cerebrospinal fluid circulation assisting apparatus

Abstract

The invention discloses a cerebrospinal fluid circulation assisting apparatus, which comprises an artificial cerebrospinal fluid import catheter, a cerebrospinal fluid export catheter and an infusion device, wherein a liquid outlet end of the artificial cerebrospinal fluid import catheter and a liquid inlet end of the cerebrospinal fluid export catheter are arranged in a cerebral ventricle of a human body, and the liquid outlet end is located at the back side of the liquid inlet end; a liquid outlet of the cerebrospinal fluid export catheter is arranged in an abdominal cavity of the human body; the cerebrospinal fluid export catheter is provided with a one-way liquid storage bag and a pressure control valve; the infusion device comprises an automatic control infusion pump and an infusion bag; the automatic control infusion pump comprises a shell and a microprocessor located in the shell; a cavity, which is used for accommodating the infusion bag, is formed in the shell; a liquid conveying mechanism, which is used for controlling artificial cerebrospinal fluid in the infusion bag to be inputted into the cerebral ventricle of the human body according to a preset quantity, is arranged in the cavity; the liquid conveying mechanism is connected to the microprocessor; a liquid discharging needle of the infusion bag is connected to an L-shaped nondestructive needle by virtue of a connecting tube; and the L-shaped nondestructive needle is inserted on an infusion seat which is connected to the liquid inlet of the artificial cerebrospinal fluid import catheter and is buried in a subcutaneous breast when the artificial cerebrospinal fluid is replenished.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cerebrospinal fluid circulation assisting device for Alzheimer's disease or other diseases with cerebrospinal fluid generation, exchange and discharge obstacles. Background technique [0002] With the advent of the era of population aging, the absolute number of Alzheimer's disease (senile dementia) patients related to aging is increasing, which has brought serious social problems. However, except for two types of drugs, cholinesterase inhibitors and excitatory amino acid antagonists, which can slightly delay the disease, other treatment options for different pathological links of Alzheimer's disease are still in various stages of research. Cerebrospinal fluid circulation (including production, exchange and discharge) disturbance is considered a pathological feature of Alzheimer's disease. Normal cerebrospinal fluid is updated 4 times a day, but patients with this disease only 1...
