Abstract
The utility model discloses the new catheters monitored for invasive angiosthenia characterized by comprising catheter body (1) has with the distal end of contacts blood and positioned at extravascular proximal end；And several micro pressure receptors (2), it is arranged on the catheter body (1) inner wall, and be located at the distal end of the catheter body (1), the micro pressure receptor (2) is completed signal through conducting wire and exported.New catheter provided by the utility model for invasive angiosthenia monitoring, structure is simple, easy to operate.
Description
Technical field
The utility model relates to technical field of medical equipment, in particular to a kind of novel leading for invasive angiosthenia monitoring
Pipe.
Background technique
Invasive angiosthenia monitoring is adapted to seriously disease, in surgical procedure, can be with for accurately detecting patient's arterial pressure
Real-time value can be according to red artery waveform variation come the contractility of discriminatory analysis cardiac muscle.
Implementation method needs arterial duct, pressure connection tube, pressure transducer, continuous flushing system, pressure detecting at present
Instrument.
Percutaneous Radial Artery Cannulation method is usually used in radial artery, femoral artery, and arterial duct enters from puncture place, is placed in needs
The intravascular of splenium position is surveyed, external catheter interface pipe is connected into pressure measuring unit.
Pressure connection tube needs to connect pressurization bag of saline and is rinsed exhaust with physiological saline, needs when connecting line changes
It repeats to be vented.Pressure sensor needs and measuring point is located at same level height and is exhausted school zero, patient body position change or
Need to adjust pressure sensor height school zero again after the variation of person's bed height.Pressure piping and conduit and pressure sensor junction
It is easy to cause leakage gas leakage effect pressure accuracy, pressure piping distortion also will affect pressure accuracy.
Utility model content
To solve the above-mentioned problems, the utility model aim is to provide a kind of novel leading for invasive angiosthenia monitoring
Pipe, structure is simple, easy to operate.
Based on the above issues, technical solution provided by the utility model is:
New catheter for invasive angiosthenia monitoring comprising:
Catheter body has with the distal end of contacts blood and positioned at extravascular proximal end；And
Several micro pressure receptors are arranged on the catheter body inner wall, and are located at the catheter body
Distally, the micro pressure receptor completes signal output through conducting wire.
In one of them embodiment, the catheter body includes the first conduit and is arranged in outside first conduit
Second conduit of side forms closed accommodating chamber, the micro pressure impression between first conduit and second conduit
Device is arranged on the inner wall of first conduit, and the wire arrangements are in the accommodating chamber and defeated through second conduit outer wall
Out.
In one of them embodiment, the proximal end of the catheter body is equipped with connector, and the connector has interval
Data cable connector and pipe joint, the data cable connector be connected to the accommodating chamber so that the conducting wire exports, it is described to lead
Pipe fitting is connected to first catheter interior.
In one of them embodiment, the connector is in Y type.
In one of them embodiment, the pipe joint is set in the catheter body, the data cable connector
It is extended to outside the pipe joint by the conduit joint outer wall.
Compared with prior art, the utility model has the advantages that:
Using the technical solution of the utility model, when use by conduit by enter at puncture need to measure it is intravascular,
Micro pressure receptor can detect intravascular pressure and export through conducting wire to pressure detecting instrument, and pressoreceptor position and target are surveyed
Position consistency is pressed, without considering that level height adjusts, avoids repeating school zero, saves pressure connection tube and pressure transducer, remove
Intermediate link piping connection avoids the problem of the inaccuracy of pressure detection data caused by pipeline liquid leakage gas leakage, at the same also avoid because
Waveform attenuating caused by pressure piping transmits, the guide-tube structure is simple, easy to operate, and detection is quickly accurate.
Detailed description of the invention
It, below will be to required in embodiment description in order to illustrate more clearly of the technical solution of the utility model embodiment
