Abstract
The utility model relates to a novel thrombus suction catheter, including the suction tube, the suction tube is including compiling net suction tube main part and compiling net suction tube head end, it is equipped with the guide chamber to compile net suction tube head end suction end, the guide chamber is tubulose and parallel with the axis of compiling net suction tube head end, the guide chamber is located the one end of compiling net suction tube head end pump orifice and outwards extends, division has on the other end net suction tube head end lateral wall on the regular payroll the through -hole along the axial, volume net suction tube head end, other end connection luer connector are connected to volume net suction tube main part one end, one -way valve body is installed to the luer connector other end, check valve body coupling suction device, suction device is the aspirator, the aspirator passes through the connecting pipe and links to each other with the suction catheter tail end. The utility model discloses aspirate the in -process at the thrombus, lead pipe body part with quick suction of thrombus, adopt the one way check valve technique, but prevent the emergence of the thrombus incident of droing in the at utmost.
Description
Technical field
This utility model belongs to Biochemical analyzer technique with the apparatus field in arteria coronaria, particularly relates to a kind of novel thrombus suction catheter.
Background technology
The main cause of ST-Elevation Acute Myocardial Infarction (STEMI) is unstable atheromatous plaque ulceration, Acute thrombosis makes obliteration, causes the necrosis of corresponding cardiac muscle.Emergency PCI (PCI) effectively can open infarct-related artery, recovers Myocardial Perfusion.But in interventional procedure, the patient of about 13% ~ 15% there will be " slow blood flow " or " fluoride-free flux " phenomenon, research display, the come off distal vessels thromboembolism that causes of microthrombus may be one of its important mechanisms occurred.Therefore, the generation that Biochemical analyzer device can reduce fluoride-free flux is to a certain extent applied in theory.In recent years along with the accumulation of evidence-based medical, the using value of thrombus suction catheter in emergency PCI gets the nod gradually, thinks obviously to reduce fluoride-free flux incidence rate, improve the blood flow state of target vessel and improve clinical prognosis.Use more suction catheter ubiquity problem clinically at present: cannot the coming off of effectively pre-preventing thrombosis, in aspiration procedure, there is certain danger.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of novel thrombus suction catheter, adopts one-way cock technology, and in upper guarantee aspiration procedure, thrombosis can not come off to greatest extent.
This utility model solves the technical scheme that its technical problem adopts: provide a kind of novel thrombus suction catheter, comprise suction tube, described suction tube comprises netting suction tube main body and netting suction tube head end, described netting suction tube head end aspiration end is provided with lead-in cavity, described lead-in cavity in a tubular form, and with the axis being parallel of netting suction tube head end, one end that described lead-in cavity is positioned at netting suction tube head end pump orifice stretches out vertically, the other end has through hole on netting suction tube head end sidewall, described netting suction tube main body one end connects netting suction tube head end, the other end connects female Luer, the described female Luer other end is provided with check valve body, described check valve body connects aspirator, described aspirator is suction pump, described suction pump is connected with suction catheter tail end by connection tube.
Silica gel check valve sheet is provided with in described check valve body.
Described suction tube main body is equipped with release of tension cover near female Luer position.
Described suction catheter total length is 120-150cm.
Beneficial effect
The utility model has the advantage of, in Biochemical analyzer process, by quick for thrombosis suction catheter body, adopt one-way cock technology, the generation of thrombus breaks loose event can be prevented to the full extent.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth this utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of this utility model.In addition should be understood that those skilled in the art can make various changes or modifications this utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read this utility model instruction.
As shown in Fig. 1 to 5, a kind of novel thrombus suction catheter, comprise suction tube, described suction tube comprises netting suction tube main body 5 and netting suction tube head end 6, described netting suction tube head end 6 aspiration end is provided with lead-in cavity 7, described lead-in cavity 7 in a tubular form, and with the axis being parallel of netting suction tube head end 6, one end that described lead-in cavity 7 is positioned at netting suction tube head end 6 pump orifice stretches out vertically, the other end has through hole on netting suction tube head end 6 sidewall, described netting suction tube main body 5 one end connects netting suction tube head end 6, the other end connects female Luer 3, described female Luer 3 other end is provided with check valve body 1, described check valve body 1 connects aspirator, described aspirator is suction pump, described suction pump is connected with suction catheter tail end by connection tube.
Silica gel check valve sheet 2 is provided with in described check valve body 1.
Described suction tube main body 5 is equipped with release of tension cover 4 near female Luer 3 position.
Described suction catheter total length is 120-150cm.
In actual use, first carry out coronary angiography, distinguish the thrombosis position in arteria coronaria, carry out Biochemical analyzer art.When performing the operation, first using normal saline to rinse suction catheter, guaranteeing without gas in suction catheter, and connect suction pump.With 0.014 " seal wire by thrombosis place to coronary artery far-end, along 0.014 " seal wire conveying suction catheter to thrombosis place.Behind DSA radiography determination suction catheter position, start vacuum suction, and pin suction pump.Now, move suction catheter slowly, until suction part blood in suction catheter.Keep negative pressure state, extract suction catheter out rapidly, and rinse suction catheter, take the circumstances into consideration to carry out Biochemical analyzer art next time.This suction catheter is provided with one-way cock, after thrombosis is inhaled into, because of the existence of one-way cock, can prevent the generation of thrombus breaks loose event to greatest extent.
