Description

External drainage monitoring and management system

Technical Field

The utility model relates to the technical field of medical equipment, more specifically relates to an outer drainage guardianship management system.

Background

Drainage is a common treatment means in the surgical field, such as cerebrospinal fluid drainage, thoracic drainage, abdominal drainage and the like, and aims to guide out liquid or pus and blood accumulated in human tissues or body cavities, relieve local pressure, avoid the oppression of effusion on adjacent organs and tissue damage, prevent postoperative infection and promote wound healing.

In the drainage process, the drainage volume of body fluid is important for clinical medical care personnel to observe the state of an illness, the volume of the drained body fluid is usually taken as a record basis, and the drainage volume of the body fluid can be used as one of important indexes for judging the change of the state of the illness. In the clinical nursing process, medical personnel need frequently observe, take notes drainage liquid's reserves and in time clear up drainage liquid, and work is fairly loaded down with trivial details and inconvenient.

In addition, the color, turbidity (clarity), and viscosity of the drainage fluid are also often important indicators in drainage management. The color, turbidity and viscosity of the drainage fluid reflect to some extent the condition of the tissue at the drainage site, e.g., the presence or absence of bleeding, infection, etc. The current method mainly depends on visual observation or periodic sampling of medical personnel for detection, not only increases the workload of the medical personnel, but also cannot monitor the drainage liquid in real time, thereby leading to the failure of timely understanding the pathological changes and the failure of accurate analysis and judgment of wound healing and drainage processes.

When various factors cause damage in tissues such as liver, brain and the like, monitoring of pressure and oxygen content in the tissues can better assist medical personnel in judging the illness state and the rehabilitation condition of a patient, and the method has important significance in diagnosis/treatment of diseases. In the case of craniocerebral injury, the continuous increase of intracranial pressure can cause the pressure displacement of brain tissues to cause cerebral hernia, which leads to serious brain function loss and even brain death. Therefore, for a patient with a damaged cranium brain, the pressure and oxygen content in the brain tissue of the patient need to be monitored to know the brain condition of the patient.
