Background technology
Acute myocardial infarction is because coronary artery blood supply drastically to be reduced or interrupts, and makes corresponding cardiac muscle seriously and enduringly
Ischemia causes myocardial necrosis.Numerous studies show, most of acute myocardial infarction be to cause vascular occlusion due to thrombosis and
Cause.Therefore, the most quickly remove removing thrombus, to open blood vessel recovery supply of blood flow, be the key for the treatment of acute myocardial infarction.
Having had thrombus suction catheter, the flexible embolus wherein produced in aspirating coronary artery is with new
Thrombosis, can slow down thrombosis blocking blood flow, recovers blood supply, it is to avoid the problems such as acute myocardial infarction.On Clinical practice, blood
Bolt suction catheter inserts from radial artery or femoral artery, and its far-end enters diseased region, uses syringe to carry out at the seat of near-end
Suction, enters main body tube by negative pressure by Biochemical analyzer, to eliminate the thrombosis in lesion locations.
But during Biochemical analyzer, inevitably cause thrombosis to rupture, form smaller thrombosis, without
In time microthrombus it is controlled or aspirates, then can cause the movement of microthrombus, enter other positions with blood circulation, to patient
Cause unpredictable risk.

Bolt suction catheter.
In order to solve above technical problem, the technical solution adopted in the utility model is: the blood of a kind of band self-expanding filter screen
Bolt suction catheter, including seal wire, it also includes main body tube, seat, self-expanding filter screen；The head end of main body tube and the end of seat are by adding
Strong part is connected；Reinforcement is placed on main body tube and seat；Main body tube is structure as a whole, by suction tube, filter screen pipe, catheter tip
End composition；Filter screen pipe is arranged at the lower end of suction tube；The inside end of filter screen pipe is provided with developing ring；
Seat includes suction chamber, filter screen chamber, and filter screen chamber is arranged at the lower section of suction chamber；Filter screen chamber is connected with filter screen pipe；Take out
Inhale chamber to be connected with suction tube；The head end in suction chamber and filter screen chamber is provided with female Luer；Seal wire through filter screen chamber, filter screen pipe,
Developing ring passes from catheter tip；Self-expanding filter screen is connected to the end of seal wire.
The mark line of mark distance effect it has been provided with on main body tube.Self-expanding filter screen in filter screen pipe in contraction-like,
Ink vessel transfusing expanse becomes filter screen shape；The smooth of the edge of self-expanding filter screen.The mesh number of self-expanding filter screen is 10～200 mesh.
This utility model simple in construction, easy to operate, design science are reasonable, can effectively promote Biochemical analyzer effect, remove
Tiny thrombosis brings the potential risk of patient.

Detailed description of the invention
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figs 1-9, this utility model includes seal wire 5, and it also includes main body tube 1, seat 2, self-expanding filter screen 4；Main body
The head end of pipe 1 is connected by reinforcement 3 with the end of seat 2；Reinforcement 3 is placed on main body tube 1 and seat 2；Main body tube 1 is one
Body structure, is made up of suction tube 101, filter screen pipe 102, catheter tip 103；Filter screen pipe 102 is arranged at the lower end of suction tube 101；
The inside end of filter screen pipe 102 is provided with developing ring 6；
The mark line that can identify distance it is provided with on main body tube 1.The material of main body tube 1 can be three layers of braided tube, internal layer
For politef, braid is stainless steel silk, and outer layer is Pebax；Can also be the extruding pipe of homogenous material, such as Pebax, Buddhist nun
Dragon；
Seat 2 includes suction chamber 201, filter screen chamber 202, and filter screen chamber 202 is arranged at the lower section of suction chamber 201；Filter screen chamber 202 with
Filter screen pipe 102 is connected；Suction chamber 201 is connected with suction tube 101；The head end in suction chamber 201 and filter screen chamber 202 is provided with Shandong
That joint 203；The material of seat 2 can be Merlon, polrvinyl chloride；
Seal wire 5 through filter screen chamber 202, filter screen pipe 102, developing ring 6 pass from catheter tip 103；Self-expanding filter screen 4 connects
End at seal wire 5.
Self-expanding filter screen 4 in filter screen pipe 102 in contraction state, in blood vessel 7 expanse become filter network state.Self-expanding
