System and method for detecting cerebrospinal fluid shunt flow

Abstract

The invention relates to a cerebrospinal fluid shunt flow detection system and method. The cerebrospinal fluid shunt flow detection system comprises a MCU module, a computer connected to the MCU module, a signal processing module and a thermal excitation driving module, the thermal excitation driving module is further connected with a thermal conduction device through a cooling module, and the signal processing module is further connected with a signal acquisition module; the MCU module controls the operation of the cooling module through the thermal excitation driving module, and a thermal excitation signal is transmitted through the thermal conduction device so as to change the temperature of the cerebrospinal fluid at a thermal excitation point; and the signal acquisition module collects a cerebrospinal fluid temperature signal at a sampling point, and the signal processing module performs signal preprocessing and A / D conversion and transmits the processed signal to the MCU module for calculating the cerebrospinal fluid shunt flow and uploading the calculated data to the computer. The cerebrospinal fluid shunt flow detection system is applied to the thermal conduction technologyto detect the cerebrospinal fluid shunt flow for the first time and can simulate the detection of the cerebrospinal fluid shunt flow of patients under any condition. Compared with the existing X-CT and MRI equipment, the cerebrospinal fluid shunt flow detection system has high efficiency and no radiation, and saves money. In addition, the cerebrospinal fluid shunt flow detection system only needsto adopt one sampling point to achieve the detection of the cerebrospinal fluid shunt flow.

Description

technical field [0001] The invention belongs to the application of thermodynamics and information science and technology in biomedicine, and in particular relates to a cerebrospinal fluid shunt flow detection system and method. Background technique [0002] Hydrocephalus is a disease in which the cerebrospinal fluid that circulates in the subarachnoid space surrounding the brain and spinal cord increases or accumulates abnormally, causing the cerebrospinal fluid to press on the brain and damage the medulla that passes through the foramen magnum. [0003] Cerebrospinal fluid shunt is a neurosurgical operation with obvious effect in the treatment of hydrocephalus, such as figure 1 The part of the pipeline implanted in the human body is shown in . Insert a silicone catheter into the ventricle, and use a set of one-way valves to drain the excess cerebrospinal fluid blocked by the arachnoid into the abdominal cavity for reabsorption. [0004] Surgery can quickly improve the neu...
