It is preceding detection pulmonary artery pressure mainly by echocardiogram and right catheterization, but for infant, according to pulmonary arterial pressure/
Body arterial pressure (Pp/Ps)The degree of ratio in judgement pulmonary hypertension has more scientific meaning.
To be performed the operation with the first heart of pulmonary hypertension, pulmonary hypertension crisis and Low output are the main reason for Postoperative determination are bad,
Therefore it is necessary that monitoring pulmonary artery pressure, which and guides the application of post-surgical vascular active medicine, in real time in art.It is at present to use more
Teflon catheter or epidural catheter insert main pulmonary artery annulus distal end and carry out pulmonary artery monitoring, and its shortcoming is Lumen catheter
Process may occur bleeding even pericardial tamponade.Adult or larger children can be determined by floating catheter pulmonary artery incarceration pressure and
Reflection left atrial pressure indirectly.But the infant Intracardiac Malformations of the particularly complicated first heart of the first heart are complicated, conduit is not easy in place, and is floated
Floating conduit expensive price.Therefore, more using direct left room inlying catheter manometric method.
The method of left room inlying catheter is broadly divided into 2 kinds at present:1. single lumen catheter is placed to the left heart through wall of the chest RSPV
Room, shortcoming are that bleeding even pericardial tamponade may occur for the process of Lumen catheter;2. through superior vena cava atrium sinistrum catheter retaining method,
It is divided into three chamber CVCs of single lumen catheter, double channel catheter and improvement(The indwelling microtubular in the center cavity of conduit), through room
Interval or oval foramen, which insert monitoring PLA left atrial pressure, this method in atrium sinistrum, may increase patient's catheter retaining and central venous puncture
Risk.Improveing three chamber CVCs reduces internal jugular vein puncture number and catheter retaining number, but microtubular easily slides out
To atrium dextrum, and the position of microtubular can not be adjusted at any time, therefore do not reach and monitor PLA left atrial pressure and the mesh of pulmonary arterial pressure at any time
's.
The content of the invention
The problem of in order to overcome existing left room pressure-measuring pipe to exist, the utility model are led in reservation three chamber central veins of improvement
Innovated on the basis of pipe advantage, infusion administration, measure central venous pressure, PLA left atrial pressure and pulmonary arterial pressure is entered simultaneously
OK.
Technical scheme is used by the utility model solves its technical problem:
The utility model includes double channel catheter and epidural catheter, and the double channel catheter includes centre pipe and collateral
Conduit, the outer end of the centre pipe are connected with breeches joint, and the breeches joint is in certain angle formed with straight mouth and with straight mouth
The side port of degree, it is characterized in that:The epidural catheter is integrated into centre pipe via the straight mouth, and epidural catheter compares center
Conduit is grown, and epidural catheter end joint can connect syringe or pressure converter, and epidural catheter exposes centre pipe part
Sealed by transparent folding thin-film, epidural catheter can move along in centre pipe, between centre pipe and collateral conduit
Leave opening.
Compared to prior art, the utility model gives a transparent folding thin-film sealing, Epidural cavity outside epidural catheter
Conduit can as needed move epidural catheter and be inserted through atrial septum or oval foramen along main in-pipe, art Chinese and foreign department doctor
PLA left atrial pressure is monitored in atrium sinistrum, also can monitor pulmonary arterial pressure through tricuspid valve to pulmonary artery, anesthetist can be in the case of sterile
The position of epidural catheter is adjusted at any time, when not needing continuous monitoring left atrial pressure or pulmonary arterial pressure, can extract Epidural cavity out
Conduit, without the whole ductus venosus of movement, operation difficulty is reduced, reduces complication.Epidural catheter position is controllable, avoids
The landing of epidural catheter, can also solve the arrhythmia cordis caused by epidural catheter stimulates, it is simple in construction, easy to operate.
