Description
Technical Field
The utility model relates to a suspension device, in particular to a suspension device for suspending a ventricular drainage device.
Background
The neurosurgical critical patient often has a plurality of drainage tubes coexisting, and the placement position of the ventricular drainage tube is the key for ensuring the functions of the drainage tubes, so that the neurosurgical critical patient has important clinical significance for monitoring the illness state of the patient and promoting the rehabilitation of the patient.
Cerebrospinal fluid is a colorless, transparent, sediment-free fluid that flows within the ventricles, central canal, and subarachnoid space. The total amount of cerebrospinal fluid is 100-150 ml in normal adult (or 70-160 ml, about 50% in the cranium, 50% in the spinal cord). The production rate of cerebrospinal fluid is 0.3ml/min, and the daily secretion is 400-500 ml. To maintain a constant circulation of 150ml of cerebrospinal fluid in the ventricular system and subarachnoid space, the amount of cerebrospinal fluid absorbed intravenously and secreted is approximately 450 ml/d. Pathological conditions can affect cerebrospinal fluid production, secretion, and circulation. The regulation of intracranial pressure is mainly realized by increasing and decreasing the cerebrospinal fluid volume, generally, a lateral ventricle is punctured by drilling a hole through a skull or a taper hole, a drainage tube is placed to drain cerebrospinal fluid to the outside of a body, and the method is one of the commonly used treatment measures for reducing intracranial pressure, discharging ventricular hematocele and reducing wound cerebrospinal fluid leakage after craniocerebral operation and is simultaneously used for ventricular hemorrhage of various reasons.
Nursing of cerebrospinal fluid drainage is vital, strict aseptic operation is required, infection is prevented, drainage speed and quantity are controlled, the drainage tube is kept smooth, changes of color, property and quantity of drainage liquid are observed, the ventricular drainage height is strictly controlled, and the drainage effect is directly determined by the height of the drainage device. The height of the drainage device is based on the tragus when the patient is in the supine position, and the lateral position is based on the median sagittal plane (lateral ventricle level). The highest point of a drainage tube (an inlet for drainage liquid to enter a drainage bag/bottle) of the drainage device is 10-15 cm above the base line, and the highest point should not exceed 20 cm. When adjusting the height of the patient's bedside, need to pay close attention to the height of the drainage pipeline, hang the drainage device on the infusion support in the prior art, the nursing staff need to clamp the drainage tube before adjusting the height of the bedside, adjust the height of the drainage device manually once more after adjusting the height of the bedside to meet the standard requirement, then open the drainage tube. If the user forgets to clamp or open the drainage tube in the operation process, or the height of the drainage device is not accurate due to manual adjustment, very serious results can be caused. Whether a patient tolerates drainage clamping or not also requires strict clinical evaluation and imaging examination, and especially for some patients with strict drainage pressure requirements, if sudden opening of drainage after clamping easily causes sudden changes of pressure gradient, easy risks of bleeding and the like, the continuous drainage strategy for such patients is the safest for the patients.
In order to solve the above problems, a person skilled in the art has proposed an adjustable suspension bracket, in which an adjustable bracket is fixed to a patient's bedside, and the patient's bedside is lifted up with the adjustable bracket, but the height of the bedside is different due to different lifting angles of the bedside, and the lifting distance of the bracket cannot completely meet the standard requirements, and still a road protection person is required to manually adjust the height of the drainage pipeline, so that the above problems cannot be fundamentally solved.
