Description
Technical Field
The utility model belongs to the field of medical appliances, in particular to a ventricular drainage tube.
Background
Ventricular drainage tubes are commonly used in the field of neurosurgery craniotomy and are used for feeding and draining the drug to the ventricles, the drainage tube comprises two cavities, one cavity corresponds to a drug feeding path, and the other cavity corresponds to a drainage path, but the two cavities of the drainage tube used in each hospital are designed side by side at present, for example, as described in patent ZL200520125493.8 (a ventricular drainage tube), the inner cavity of the drainage tube is divided into a main drainage tube cavity and a fine drainage tube cavity. The structure has the disadvantages that the structure is not suitable for large-area accurate administration and drainage, and the structure is inconvenient to fix on the scalp and has poor use comfort for patients.
Disclosure of Invention
To the deficiency that the prior art exists, the utility model provides a ventricular drainage tube.
In order to solve the current problem, the utility model discloses realize according to following technical scheme: the utility model provides a ventricle drainage tube, including the outer tube, the outer tube rear end is equipped with route of dosing and drainage route, the inboard of outer tube lower part is equipped with circular connecting piece, circular connecting piece also is equipped with route of dosing and drainage route from upper portion to lower part, the route of dosing and the drainage route on upper portion are the shape side by side, the route of dosing and the drainage route of lower part are the inner circle, the outer lane shape, circular connecting piece's lower surface is the arc, the circular connecting piece downside is the insert tube, the insert tube also is the inner circle, the outer lane shape, the front end of inner circle is equipped with a plurality of through-holes, the front end side of outer lane also is equipped with a plurality of through-holes, outer tube and circular connecting piece pass through the interference and insert the connection, circular connecting piece and insert the connection also through the interference.
The outer sleeve has certain elasticity.
The administration path and the drainage path at the rear end of the outer sleeve are Y-shaped, the drainage path is perpendicular to the circular connecting piece, and the administration path and the circular connecting piece form a non-90-degree angle.
The utility model has the advantages that: can realize large tracts of land accurate dose and drainage, and be convenient for fix on the scalp, improve patient's comfort level in use.
