Drainage monitoring system

Abstract

The invention relates to a drainage monitoring system, which at least comprises a control module, a sensor and an alarm module,wherein the control module is set to carry out flow monitoring according to the following mode: S1, the control module receives the current intracranial pressure P0 detected by a first sensor; S2, the control module sets a drainage period T0; S3, the control module presets the maximum drainage amount in the drainage period T0; S4, the control module calculates the current drainage amount and the residual drainage amount according to the actual drainage speed V1 and the drainage time which are detected by a second sensor, and the size of a pipeline; S5, the control module calculates the maximum drainage speed Vmax based on the residual drainage time; S6, the control module calculates a preset flow velocity Vmin required for reaching the normal intracranial pressure in the drainage period T0 based on the pressure difference between the current intracranial pressure P0 and the normal intracranial pressure; and S7, the control module triggers an alarm system based on the relation between the actual flow velocity V1 detected by the second sensor and the minimum flow velocity Vmin and the maximum flow velocity Vmax. According to the invention, the system is flexible in adaptive adjustment and convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a drainage monitoring system. Background technique [0002] Hydrocephalus is divided into two types, one is obstructive hydrocephalus, and the other is hydrocephalus caused by secretion transformation, which can cause symptoms of ataxia, gait, obsession, and incontinence. If it is serious, external ventricular drainage can be used to improve cerebrospinal fluid circulation and brain pressure, and improve the symptoms caused by increased intracranial pressure due to hydrocephalus. Therefore, external ventricular drainage is mainly used to treat hydrocephalus to improve the symptoms of ataxia, dementia and incontinence. [0003] Since the production rate of effusion is extremely slow, and the production rate of different patients or even the same patient under different physiological conditions is not consistent, when the patient produces effusion slowly, it needs to be dr...

However, this device does not have the function of monitoring the drainage volume, and the judgment of the drainage volume is based on manual reading of the scale of the drainage bag. Since the drainage speed of the ventricle is relatively slow, the existing drainage bag needs to be sucked because the liquid level in the drainage bag rises by 1 mm. There is a lot of liquid and it takes a long time, it is not easy to observe the change of liquid volume, and it is easy to cause delay

For some special situations, such as partial blockage of the drainage catheter or drainage circuit breakage, it is impossible to monitor in time, especially in the case of rapid changes in the intracranial pressure of the patient, it is impossible to detect and control the solenoid valve to adjust the flow rate in time to adapt to the change.
