Abstract
The invention relates to a high-flow anti-blockage drainage pipe comprising an outer slotted pipe section, a closed pipe section and a transition section which connects the two pipe sections; the inside of the slotted pipe section is a drainage channel in which radial support bodies divide the cross section of the pipe into N sector areas; the outer wall of the pipe body is provided with N strip-shaped notches which correspond to the sector areas as drainage ports; N ribs which are protruded to an axis are arranged in a closed pipeline; and in the transition section, the ribs are connected with the support bodies, and N is more than or equal to 3. The drainage pipe has high flow, the ribs are arranged in the closed pipeline, and the high-flow anti-blockage drainage pipe has flow capacity and high anti-blockage performance after being bent.
Description
Technical field
The present invention relates to the technical field of medical catheter, particularly relate to the anti-blocking drainage catheter of a kind of large flow.
Background technology
drainage catheter of the prior art, its conduction hole is generally circular port, be evenly distributed on the inner end of body, when this class conduction hole contacts with tissue, easily inhale the soma of hurting sb.'s feelings, Chinese patent: 200920167107.X discloses a kind of without transition deformation medical catheter, conduit in this patent has adopted bar-shaped trough as draining hole, successful solution this problem, can farthest reduce the injury to tissue, simultaneously its through-current capability is compared circular port and has been promoted much as the conduit of conduction hole, but the closed section of this conduit also exists and holds susceptible to plugging problem when giving a discount, through-current capability also has the space that promotes simultaneously.
Summary of the invention
To the objective of the invention is in order addressing the above problem, to provide a kind of large flow anti-blocking drainage catheter.
Technical scheme of the present invention is: the anti-blocking drainage catheter of a kind of large flow, comprise outside be barrel section, sealing pipeline section and connection changeover portion both, described barrel intrasegmental part is that radial supporter is divided into the cross section of pipe the drainage channel of N sector region, tube wall is provided with the N corresponding with sector region bar shaped notch as draining hole, described closed conduct inside is provided with N to the rib of axle center projection, link into an integrated entity at the inner described rib of changeover portion and described supporter, N 〉=3.
The generatrix direction of described bar-shaped trough opening's edge pipe outer wall extends.
Described bar shaped notch extends twist around the tubular axis line.
The width of described bar shaped notch is less than the arc length of sector region, is respectively equipped with the edge of arc in notch both sides.
Described rib extends along the generatrix direction of inside pipe wall.Described this drainage catheter adopts polyurethane material to make.
Beneficial effect of the present invention
This drainage catheter flow is large, is provided with rib at closed conduct, also possesses through-current capability after bending, and anti-blocking performance is strong.
Link into an integrated entity in changeover portion interior ribs and supporter, make seamless link between rib and supporter, the resistance when reducing liquid flow is avoided forming in changeover portion and is stopped up.

The specific embodiment
Embodiment one: referring to Fig. 1-5, the anti-blocking drainage catheter of a kind of large flow in figure, comprise outside be barrel section, sealing pipeline section and connection changeover portion both, described barrel intrasegmental part is that radial supporter is divided into the cross section of pipe the drainage channel of N sector region, tube wall is provided with the N corresponding with sector region bar shaped notch as draining hole, described closed conduct inside is provided with N to the rib of axle center projection, link into an integrated entity at the inner described rib of changeover portion and described supporter, N=4.The generatrix direction of described bar-shaped trough opening's edge pipe outer wall extends.The width of described bar shaped notch is less than the arc length of sector region, is respectively equipped with the edge of arc in notch both sides.Described rib extends along the generatrix direction of inside pipe wall.Described this drainage catheter adopts polyurethane material to make.
Embodiment two: referring to Fig. 6, the anti-blocking drainage catheter of a kind of large flow, comprise outside be barrel section, sealing pipeline section and connection changeover portion both, it is characterized in that described barrel intrasegmental part is that radial supporter is divided into the cross section of pipe the drainage channel of N sector region, tube wall is provided with the N corresponding with sector region bar shaped notch as draining hole, described closed conduct inside is provided with N to the rib of axle center projection, link into an integrated entity at the inner described rib of changeover portion and described supporter, N=4.Described bar shaped notch extends twist around the tubular axis line, can increase like this area of draining hole on unit length, promotes through-current capability.The width of described bar shaped notch is less than the arc length of sector region, is respectively equipped with the edge of arc in notch both sides.Described rib extends along the generatrix direction of inside pipe wall.Described this drainage catheter adopts polyurethane material to make.
N in embodiment one, two can also be 3 or 5, and this numerical value normal root really comes suitable selection according to pipe diameter size.
