Abstract

The utility model relates to a double-cavity ventricular drainage tubes used for the intraventricular hemorrhage, the intracerebral hematoma, the chronic subdural hematoma and hydrops, and the brain abscess. The end face of an end of the drainage tube (1) is in the closed state; a washing channel is arranged in the pipe wall of a single side of the drainage tube (1); an end of the washing channel is connected with the washing tube (2) on the drainage pipe wall; the two sides of the drainage pipe wall near to the sealing end face (5) are respectively provided with a drainage tube outlet (3) and a washing channel outlet (4); the drainage tube outlet (3) and the washing channel outlet (4) are in the shape of a roundness or an ellipse. The double-cavity ventricular drainage tubes have a simple structure and convenient use; the drainage and the washing can be processed continuously, the trauma face can not be increased, and the surgery risk can be decreased.

Description

The two-chamber ventricular drainage tube

Affiliated technical field

This utility model relates to a kind of two-chamber ventricular drainage tube that is used for drains such as ventricular hemorrhage, intracerebral hematoma, chronic subdural hematoma and hydrops, brain abscess.

Background technology

At present, existing ventricular drainage tube is single chamber, when the ventricles of the brain and blood (clot cast) or intracerebral hematoma drain are insufficient, need flushing or injects the fibrinolytic medicine, injected by single chamber, this will cause: the drug dose of (1) injection ventricles of the brain and intracerebral hematoma intracavity is limited; (2) local intracranial pressure increases; (3) can not constant drainage and flushing.As the need continual rinsing, generally respectively put into a drainage tube at the left and right sides ventricles of the brain, one is used for drain, and one is used for flushing, has so just increased operation wound and operating time, has increased risk.

Summary of the invention

At above deficiency, this utility model provide a kind of can constant drainage and the two-chamber ventricular drainage tube of flushing.

The technical scheme that this utility model is taked is, a kind of two-chamber ventricular drainage tube, the end face of drainage tube one end is closed state, be provided with irrigation channel in the tube wall of drainage tube one side, one end of irrigation channel is communicated with the syringe pipe on the drainage wall, and the drainage wall both sides of close Closed End are respectively equipped with drainage tube outlet and irrigation channel outlet.

Drainage tube outlet described in the utility model and irrigation channel outlet are rounded or oval.

The beneficial effects of the utility model are, simple in structure, easy to use, be provided with irrigation channel in the tube wall of drainage tube one side, one end of irrigation channel is communicated with the syringe pipe on the drainage wall, the drug dose that can inject the ventricles of the brain and intracerebral hematoma intracavity is bigger, sustainablely carries out drain and flushing, and local intracranial pressure can not increase yet; The general size of the diameter of two-chamber drainage tube and single chamber drainage tube can not increase the operation wound face, has reduced operation risk; The sealing of the end face of drainage tube one end is provided with circle or the outlet of oval drainage tube and irrigation channel at drainage wall and exports, like this easy damaged ventricles of the brain soft tissue not.

Description of drawings

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.

The specific embodiment

In Fig. 1, Fig. 2, drainage tube 1 one end openings, the end face of one end is closed state, be provided with irrigation channel in the tube wall of drainage tube 1 one sides, one end of irrigation channel is communicated with syringe pipe 2 on the drainage wall, is respectively equipped with circle or outlet 3 of oval drainage tube and irrigation channel outlet 4 near the drainage wall both sides of Closed End 5.The two-chamber ventricular drainage tube can adopt silica gel tube, can directly link to each other with drainage bag at drainage tube 1 opening part during use.Syringe pipe 2 is a microtubular, and can passing through to infuse at syringe pipe 2 opening parts during use, leather strap links to each other with rinsing bottle or pass through the micro pump injectable drug.

Claims

1, a kind of two-chamber ventricular drainage tube, the end face that it is characterized in that drainage tube (1) one end is closed state, be provided with irrigation channel in drainage tube (1) the one side pipe wall, one end of irrigation channel and the syringe pipe (2) on the drainage wall are connected state, and the drainage wall both sides of close Closed End (5) are respectively equipped with drainage tube outlet (3) and irrigation channel outlet (4).

2, two-chamber ventricular drainage tube according to claim 1 is characterized in that drainage tube outlet (3) and irrigation channel outlet (4) is rounded or oval.
