Background technology
Central venous catheter external member include conduit, dilator, syringe, puncture needle, J-shaped seal wire+booster, vessel clamp+
Holder, Y shape interface.First puncture needle connection is penetrated into the main mouth of Y shape interface on the injector and by puncture needle when in use
It is interior, then carry out puncturing and blood back inspection in thoracic cavity or abdominal cavity position, fix puncture needle with handss and simultaneously J-shaped seal wire is penetrated into Y shape
In the side port of interface, J-shaped seal wire is pushed under the assosting effect of booster and is threaded back through pricker to predetermined length recession, by dilator
It is enclosed within J-shaped seal wire and the skin and subcutaneous tissue at puncture orifice is expanded, then withdraw from dilator, fixes seal wire with handss and prevent
On-slip is de- simultaneously to push sheathed catheter on J-shaped seal wire into thoracic cavity or intraperitoneal, reach withdraw from J-shaped seal wire after appropriate depth and
Conduit is stayed in puncture orifice, finally catheter port is carried out the process such as sealing and A/C is in case to thoracic cavity or Intraabdominal
Hydrops are extracted.
Conduit has at normal temperatures certain hardness, more soft so as to avoiding to human body blood in 37 DEG C or so of body temperature
The destruction of tube wall, but conduit during this soft condition is easily bent when J-shaped seal wire is withdrawn from and affects removing for J-shaped seal wire
Go out, once withdraw from failure to be accomplished by puncturing again so as to bring inconvenience to patient and doctor.
The content of the invention
The present invention seeks to withdraw from J-shaped seal wire for the existing conduit of solution limbers up when into thoracic cavity or intraperitoneal
Shi Rongyi is bent and then affects the problem withdrawn from of J-shaped seal wire and proposes a kind of disposable splanchnocoel puncture conduit.
The present invention is adopted the technical scheme that to reach above-mentioned purpose：
Disposable splanchnocoel puncture conduit, including catheter body, the conduit head end of catheter body is provided with negative pressure union joint, is leading
Tube body outer surface is provided with soft rubber layer, thin cavity pipe is provided with along catheter body trend in soft rubber layer, soft
Around catheter body circumferencial direction at least provided with a toroidal cavity in matter rubber layer, thin cavity pipe is connected with toroidal cavity, works as ring
Shape sky positive intraluminal pressure forms annular protrusion when being full of water；The aqueduct connected with thin cavity pipe is provided with catheter body, is being led
The port of water pipe is provided with positive pressure water union joint.
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
Thickness of the thickness of matter rubber layer less than toroidal cavity inner side soft rubber layer.
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, the outer surface in soft rubber layer is provided with scale value.
Preferably, the catheter body is single lumen catheter or multi-cavity catheter.
Preferably, thickness of the thickness of the soft rubber layer less than catheter body.
The present invention have the advantage that for：By soft rubber layer being set up on catheter body outer surface and soft
Thin cavity pipe and toroidal cavity are set in matter rubber layer, when malleation is full of water in toroidal cavity 13 annular protrusion is formed, so as to
It is not susceptible to bend so as to ensure that the smooth extraction of J-shaped seal wire in the barrier effect downcomer body of annular protrusion；Work as conduit
Soft rubber layer still ensures that catheter body in soft shape so as to avoid to human vas wall when body is in human vas
Destruction, the present invention is the good disposable splanchnocoel puncture conduit of a kind of compact conformation, low cost, effect.
Description of the drawings
Fig. 1 is the structural representation of the present invention；
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.
Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings.
As shown in Figure 1, Figure 2 and Figure 3, the present invention includes catheter body 7, and the conduit head end of catheter body 7 is provided with negative pressure company
Joint 1, is provided with soft rubber layer 9 on the outer surface of catheter body 7, and the thickness of the soft rubber layer 9 is less than catheter body 7
Thickness, is provided with thin cavity pipe 10, around catheter body in soft rubber layer 9 in soft rubber layer 9 along the trend of catheter body 7
7 circumferencial directions are connected at least provided with a toroidal cavity 13, thin cavity pipe 10 with toroidal cavity 13, when malleation in toroidal cavity 13
Full of formation annular protrusion 8 during water；Coupling clip 5 is provided with catheter body 7, is provided with coupling clip 5 and is connected with thin cavity pipe 10
Logical aqueduct 3, is provided with tongs 4 on aqueduct 3, and in the port of aqueduct 3 positive pressure water union joint 2 is provided with.
When J-shaped seal wire is withdrawn from 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
