Embodiment Construction

[0031] The following is a description of specific embodiments of the present invention according to the accompanying drawings.

[0032] The present invention is a rechargeable implantable automatic voltage regulation and shunt system with program control function. The system runs as figure 1 , Figure 2a and 2b As shown, the external control system 101 and the access control valve 301 can receive the pressure measurement value of the pressure sensing system 201. After the access control valve 301 receives the pressure information measured by the pressure sensing system 201, the internal control circuit will automatically adjust to make the cranial When the internal pressure stabilizes at the set pressure threshold suitable for the patient's physical condition, or when the automatic pressure adjustment threshold is not suitable for the patient's physical condition, the control circuit in the access control valve 301 can reset the pressure threshold through the external control...

Abstract

The invention discloses a rechargeable implantable automatic pressure regulating and diverting system with a program control function, and belongs to the field of medical instruments. The system includes a passage control valve, a pressure sensing system, a self-generating energy collecting system, an external control system and a drainage tube. Through the pressure feedback of the pressure sensing system and the adjustment of the external control system, the passage control valve adjusts the opening pressure or flow of a hydrocephalus valve, and drains intracranial cerebrospinal fluid to another suitable position in the body through the drainage tube, electricity required by various systems is supplied by the self-generating energy collecting system, and the drain tube is provided with ananti-freezing and antibacterial drug coating layer. The system can monitor the intracranial pressure in real time, adjust the pressure autonomously, effectively reduce related complications such as excessive or insufficient diversion, drain tube clogging, infection and the like.

Description

technical field [0001] The invention belongs to the field of medical equipment. Specifically, it relates to a rechargeable implantable automatic voltage regulation and shunt system with a program-controlled function. Background technique [0002] Hydrocephalus is a condition in which CSF accumulates in excess in the ventricles or brain tissue, often caused by an etiological disorder, birth defect, infection, cancer, hemorrhagic trauma to the brain, or aging. Excessive accumulation of CSF will cause increased intracranial pressure, which will damage brain tissue. Studies have shown that using a shunt to discharge excess CSF can effectively reduce intracranial pressure and relieve symptoms of patients. [0003] Shunt systems are generally divided into adjustable pressure systems and non-adjustable pressure systems. The non-adjustable pressure system has related complications such as excessive shunt or insufficient shunt, shunt obstruction, infection, etc., which lead to the ...
