Abstract
The utility model relates to a medical instrument, in particular to an external drainage device of ventricles of brain, which comprises an elastic plastic drainage tube. A plurality of drainage holes are arranged on the front end part of the drainage tube. The utility model is characterized in that a steel conducting wire is arranged inside the drainage tube, a development ball is arranged at the front end of the drainage tube, the rear end of the drainage tube is connected with a connecting base, the connecting base is connected with an adjusting and controlling tube, the other end of adjusting and controlling tube is connected with a columnar-shaped metering device, and an adjusting and controlling valve is arranged on the adjusting and controlling tube. The steel conducting wire is arranged inside the drainage tube of the utility model, which ensures the smooth insertion of the drainage tube to effectively protect the brain tissue from being impaired, the development ball can ensure the arranging position of the drainage tube to be more precise, which can ensure the security of the patient to the maximum extension, a plurality of drainage holes are arranged, thus the drainage holes are uneasy to be blocked, the pressure of the ventricles of brain can be adjusted through the adjusting and controlling valve, and the drainage volume can be precisely measured through the columnar-shaped metering device, which can better provide data for the operation of the doctor. The utility model has the advantages of novel design, convenient operation, secure application, and good drainage effect.
Description
Technical field:
This utility model relates to medical apparatus and instruments, specifically a kind of EVD device.
Background technology:
At present, Neurology Department, the EVD device that neurosurgery is used clinically is a drainage tube, employed material is a silica gel catheter, has only monolayer, process coarse, put the pipe difficulty, use inconvenient, the perforate of its conduit is single, cause easily in the pipe and stop up, drainage of cerebrospinal fluid is not smooth, not accurate metering this degree and X line development labelling on the conduit, in use, the CT that can't the require mental skill disconnected position of drainage tube in brain of betraing, in addition, existing EVD pipe does not have anti-reflux, regulate cerebral, the device of control drain, in clinical use, can cause drainage of cerebrospinal fluid deficiency or drain excessive like this, thereby cause severe complications, even threat to life.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of conduction hole to be difficult for stopping up, and can be retained in the ventricles of the brain intracavity a middle or short term, and can regulate the EVD device of ventricles of the brain pressure.
This utility model can reach by following measure:
A kind of EVD device, include the elastoplast drainage tube, the drainage tube leading section is provided with a plurality of conduction holes, it is characterized in that being provided with in the drainage tube steel seal wire, the drainage tube front end is provided with the development ball, and the rear end is connected with Connection Block, and Connection Block is connected with regulating tube, the regulating tube other end is connected with the column quantifier, and regulating tube is provided with controlling valve.
The steel seal wire is arranged in this utility model drainage tube; guarantee that drainage tube successfully inserts; protected cerebral tissue injury-free effectively, the position that the development ball can make drainage tube place is more accurate, at utmost guarantees patient's safety; be provided with a plurality of conduction holes; conduction hole is difficult for stopping up, and controlling valve 7 can be regulated ventricles of the brain pressure, and the cylindricality quantifier can accurately measure drainage flow; can be better for doctor's operation provides data, have modern design, easy to operate, safe in utilization, advantage such as drainage effect is good.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described:
As shown in drawings; a kind of EVD device; include elastoplast drainage tube 1; drainage tube 1 leading section is provided with a plurality of conduction holes 2; it is characterized in that being provided with in the drainage tube 1 steel seal wire 3; drainage tube 1 front end is provided with development ball 4; the rear end is connected with Connection Block 5, and Connection Block 5 is connected with regulating tube 6, and regulating tube 6 other ends are connected with column quantifier 8; regulating tube 6 is provided with controlling valve 7; controlling valve 7 is identical with existing liquid pressure regulator valve structure, and this does not give unnecessary details, and the steel seal wire is arranged in this utility model drainage tube; guarantee that drainage tube successfully inserts; protected cerebral tissue injury-free effectively, the position that the development ball can make drainage tube place is more accurate, at utmost guarantees patient's safety; be provided with a plurality of conduction holes; conduction hole is difficult for stopping up, and controlling valve 7 can be regulated ventricles of the brain pressure, and the cylindricality quantifier can accurately measure drainage flow; can be better for doctor's operation provides data, have modern design; easy to operate; safe in utilization; advantages such as drainage effect is good.
