Description

A kind of convenient conduit for removing thrombus

Technical field

The utility model relates to the field of medical instrument technology, and in particular to a kind of convenient conduit for removing thrombus.

Background technique

In ST sections of elevation myocardial infarction Urgent percutaneous coronary interventions, even if 5% ~ 15% patient opens infarct Related arteries, distal myocardium tissue cannot still obtain effective perfusion, in some instances it may even be possible to cardiac death and main bad can occur Cardiac event, slow blood flow/fluoride-free flux incidence is up to 5% ~ 25%, and fluoride-free flux can be such that Death and incidence rate of myocardial infarction increases 5 ~ 10 times.Currently, there are two ways to preventing coronary slow flow/fluoride-free flux: being controlled first is that strengthening anticoagulant, antiplatelet It treats, still, slow blood flow/fluoride-free flux incidence is still higher；Second is that using Biochemical analyzer.The pathogenesis of STEMI is mainly suffered from The intracoronary patch of person ruptures, and is partially formed thrombus.

Patent CN104586470A discloses a kind of thrombus suction catheter, including catheter body and setting in the conduit sheet The guidewire lumen of body proximal end, catheter body have suction chamber, and guidewire lumen is located at the distal medial of the suction chamber, connect with suction chamber It is logical.Seal wire enters from guidewire lumen, by suction chamber, leaves catheter body from joint.The conduit is able to solve in the prior art Thrombus suction catheter is since the smaller brought aspiration rate of the radial section of suction chamber and suction chamber product is low, suction chamber easily blocks The problem of.There is following not perfect place in conduit: it does not improve seal wire and leaves the mode of conduit, if do not solved the above problems, Seal wire is stretched out from suction chamber, and seal wire and Biochemical analyzer device cannot use simultaneously.

Patent CN206473366U discloses a kind of thrombus suction catheter of double suction chambers of band, including tube socket, proximal end push Bar, distal tube and tip, wherein one end of proximal end push rod is connect with tube socket, and the one of the other end of proximal end push rod and distal tube End connection, the other end of distal tube connect with tip, set in distal tube there are three cavity, respectively one is located in the middle seal wire Transit chamber and two are located at the suction chamber of seal wire transit chamber two sides.Since the suction chamber on both sides can be preferably in blood vessel Between part, can sufficiently be contacted with thrombus in blood vessel and clast patch, thrombus etc. all can be detached by negative-pressure ward principle by blood Pipe.Conduit has following not perfect place: first is that the conduit does not improve suction tip opening mode, suction tip is as thrombus The core part of suction catheter, opening shape are directly affected except bolt effect.Second is that not improving guidewire proximal connection type, do not have Have and shows suitable guide wire exit openings.

Utility model content

The utility model overcome the deficiencies in the prior art, the utility model provide a kind of convenient conduit for removing thrombus.

The purpose of this utility model is achieved in that

A kind of convenient conduit for removing thrombus, including injection seat, injection seat inner hollow are in three lumens of Y type, one end is Pump orifice, one end are injection port, and the other end is working hole；The working hole connection supervisor, in the junction of working hole and supervisor Equipped with stress relief；One end connection tip pipe being responsible for far from injection seat, pipe inside in tip is equipped with guidewire lumen；

The injection port connects inner tube, and for inner tube through the guidewire lumen of supervisor's connection tip pipe, guidewire lumen front end is equipped with development Label.

The injection seat is molded by polycarbonate.

The supervisor is bourdon tube, and the bourdon tube raw material is the steel wire that coating is completed；The coating is superslide coating, Silicone coating or anticoagulant coatings.

Said inner tube is multilayer pipe.

The developing mark is metal marker or barium sulfate material.

The stress relief is made of elastic material.

Tip pipe cross section is regular circle shapes, and the one end of tip pipe apart from nearly developing mark is beveling opening, arc Opening or straight line opening.

Compared with the existing technology, the utility model usefulness:

1. having two-sided suction chamber, double arc incisions can preferably be bonded thrombus, be particularly suitable for blocking venereal disease and become；

2. angular cut single side suction chamber, limited cross sections product is maximally utilized, more just big suction chamber is provided, facilitates suction big Block thrombus improves pumping efficiency；

3. spring outer tube layer using thermal contraction mode coat, with tradition squeeze out surrounding phase ratio, tube wall is thinner, macromolecule layer with Bourdon tube effectively combines, and improves the pushability and tensile resistance of supervisor, while effectively improving supervisor inner cavity, makes Biochemical analyzer more Simply, effectively；

4. after suction thrombolytic drug can be conveyed by guidewire lumen, massive is effectively detached by negative-pressure ward principle, Small patch after the control suction of drug thrombolysis, it is effective to remove lesion vessels thrombus, while slow resurgent, fluoride-free flux generation is effectively reduced Rate;

5. making material is from a wealth of sources, production cost is low, is suitable for more patients；

Detailed description of the invention

Fig. 1 is the structural schematic diagram of the utility model.

Fig. 2 is that two-sided suction chamber structural schematic diagram is managed at tip.

Fig. 3 is tip pipe single side suction chamber structural schematic diagram

Wherein, 1. tips are managed, 2. supervisors, 3. stress reliefs, 4. inner tubes, 5. injection seats, 6. injection ports, 7. pump orifices, 8. working hole, 101. developing rings, 102 guidewire lumens, 103. bourdon tubes.

Specific embodiment
