Positive pressure water connector is provided with the port of aqueduct.
Preferably, the toroidal cavity is located at the first half of catheter body；It is soft on the outside of toroidal cavity at toroidal cavity
The thickness of matter rubber layer is less than the thickness of soft rubber layer on the inside of toroidal cavity.
Preferably, coupling clip is provided with catheter body, the aqueduct connected with thin cavity pipe is provided with coupling clip,
Aqueduct is provided with tongs,
Preferably, it is provided with scale value in the outer surface of soft rubber layer.
Preferably, the catheter body is single lumen catheter or multi-cavity catheter.
Preferably, the thickness of the soft rubber layer is less than the thickness of catheter body.
Had the beneficial effect that possessed by the utility model：By set up on catheter body outer surface soft rubber layer and
Thin cavity pipe and toroidal cavity are set in soft rubber layer, annular protrusion is formed when malleation is full of water in toroidal cavity 13,
So as to be not susceptible to bending in the barrier effect downcomer body of annular protrusion so as to ensure that the smooth extraction of J-shaped seal wire；When
Soft rubber layer still ensures that catheter body in soft shape so as to avoid to human body blood when catheter body enters in human vas
The destruction of tube wall, the utility model are a kind of disposable splanchnocoel puncture conduits compact-sized, cost is low, effect is good.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 is along the profile in A-A directions in Fig. 1；
Fig. 3 is along the profile in B-B directions in Fig. 1.
Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the utility model includes catheter body 7, and the conduit head end of catheter body 7, which is provided with, to be born
Connector 1 is pressed, soft rubber layer 9 is provided with the outer surface of catheter body 7, the thickness of the soft rubber layer 9 is less than conduit sheet
The thickness of body 7, be provided with thin cavity pipe 10 along the trend of catheter body 7 in the soft rubber layer 9, it is interior around leading in soft rubber layer 9
The circumferencial direction of tube body 7 is at least provided with a toroidal cavity 13, and thin cavity pipe 10 connects with toroidal cavity 13, when toroidal cavity 13
Interior malleation forms annular protrusion 8 when being full of water；Coupling clip 5 is provided with catheter body 7, is provided with and thin cavity at coupling clip 5
The aqueduct 3 that pipe 10 connects, tongs 4 is provided with aqueduct 3, positive pressure water connector 2 is provided with the port of aqueduct 3.
When withdrawing from J-shaped seal wire in order to fix the fore-end of catheter body 7 first, the toroidal cavity 13 is located at conduit
The first half of body 7；At toroidal cavity 13, the thickness of the outside soft rubber layer 9 of toroidal cavity 13 is less than toroidal cavity 13
The thickness of inner side soft rubber layer 9, ring is formed so as to be heaved laterally when ensure that malleation is full of water in toroidal cavity 13
Shape projection 8.
