Abstract

A kind of blockage resisting hemodialysis conduit, body comprises tube chamber portion and adapter portion, inflatable chamber is inner at tube chamber, the two cross section is concentric circular, inflatable chamber is connected on lumen wall by two interlayers, tube chamber inner space except inflatable chamber is divided into two independently cavitys by interlayer, is respectively lumen of artery and venous lumen; Lumen of artery and venous lumen are respectively equipped with opening first and opening second; Inflatable chamber is provided with sacculus, and described sacculus is at opening first and opening second rear; Lumen of artery, venous lumen, inflatable chamber stretch out tube chamber and form separate lumen of artery adapter, venous lumen adapter, sacculus trachea respectively.This utility model structure is simple, and easy to operate, the highly effective blockage problem preventing hemodialysis pipe, extends the service life of hemodialysis pipe.

Description

Blockage resisting hemodialysis conduit
Technical field
This utility model relates to the hemodialysis catheter applied in technical field of medical instruments, particularly relates to a kind of blockage resisting hemodialysis conduit.
Background technology
Blood samples of patients is introduced in dialyser by hemodialysis system, utilizes semipermeable membrane both sides solute concentration difference, and through infiltration, diffusion and Ultrafiltration, reach and remove metabolite and toxicant, corrects the object of water, electrolyte balance disorder.Hemodialysis (hereinafter referred to as hemodialysis) comprises renal replacement therapies, hemoperfusion, immunoadsorption, Endotoxin adsorption and plasmapheresis etc.Each hemodialysis mode all respectively has feature, and is applicable to various disease and state, but the hemodialysis of that type all will set up arteriovenous passage, arterial end blood is introduced dialyser, through Dialysis, makes blood purification.Then the blood purified is fed back in body by vein end again.
The common a kind of method being hemodialysis conduit punctures carries out the foundation of arteriovenous passage clinically at present, and hemodialysis catheter often needs to be retained in patient body in a very long time, there will be after catheter retaining certain hour in conduit and form thrombosis, and fibrin adheres to pipe inner wall or parcel outer wall forms interior sheath and epitheca (change of fiber oversleeve sample), causes conduit portion or blocks completely.
technology contents
For solving the problem, a kind of blockage resisting hemodialysis conduit has been invented in this utility model design.
This utility model content is: a kind of blockage resisting hemodialysis conduit, and body comprises tube chamber portion and adapter portion, and tube chamber portion comprises lumen of artery, venous lumen, inflatable chamber, opening first, opening second, sacculus; Adapter portion comprises lumen of artery adapter, the adapter of sacculus trachea, venous lumen, it is characterized in that: inflatable chamber is inner at tube chamber, the two cross section is concentric circular, inflatable chamber is connected on lumen wall by two interlayers, tube chamber inner space except inflatable chamber is divided into two independently cavitys by interlayer, is respectively lumen of artery and venous lumen; Lumen of artery and venous lumen are respectively equipped with opening first and opening second; Inflatable chamber is provided with sacculus, and described sacculus is at opening first and opening second rear; Lumen of artery, venous lumen, inflatable chamber stretch out tube chamber and form separate lumen of artery adapter, venous lumen adapter, sacculus trachea respectively.
The outer wall of tube chamber portion end has two projections, form groove between two projections, a projection near tube chamber front end is taper.Lumen of artery, inflatable chamber front end are closed state.
Beneficial effect
This utility model structure is simple, and easy to operate, the highly effective blockage problem preventing hemodialysis pipe, extends the service life of hemodialysis pipe.
Accompanying drawing explanation
Sectional view when accompanying drawing 1 is sacculus closure state in blockage resisting hemodialysis dialysis catheters process;

Accompanying drawing 3 is the tube chamber sectional view of blockage resisting hemodialysis conduit;
The partial view of sectional view when accompanying drawing 4 is sacculus closure state in blockage resisting hemodialysis dialysis catheters process;
The partial view of sectional view when accompanying drawing 5 is sacculus open configuration in blockage resisting hemodialysis dialysis catheters process;
1 be lumen of artery trachea in figure, 2 sacculus tracheas, 3 venous lumen tracheas, 4 sacculus, 5 lumen of artery openings, 6 venous lumen openings, 7 tube chambers, 8 lumen of artery, 9 inflatable chambers, 10 venous lumen, 101 are adapter portion, 102 for tube chamber portion.
Detailed description of the invention
A kind of blockage resisting hemodialysis conduit, body comprises tube chamber portion and adapter portion, and tube chamber portion comprises lumen of artery, venous lumen, inflatable chamber, opening first, opening second sacculus; Adapter portion comprises lumen of artery adapter, the adapter of sacculus trachea, venous lumen, it is characterized in that: inflatable chamber is inner at tube chamber, the two cross section is concentric circular, inflatable chamber is connected on lumen wall by two interlayers, tube chamber inner space except inflatable chamber is divided into two independently cavitys by interlayer, is respectively lumen of artery and venous lumen; Lumen of artery and venous lumen are respectively equipped with opening first and opening second; Inflatable chamber is provided with sacculus, and described sacculus is at opening first and opening second rear; Lumen of artery, venous lumen, inflatable chamber stretch out tube chamber and form separate lumen of artery adapter, venous lumen adapter, sacculus trachea respectively.The outer wall of tube chamber portion end has two projections, form groove between two projections, a projection near tube chamber front end is taper.Lumen of artery, inflatable chamber front end are closed state.
In use procedure, along with the gas in sacculus is released, lumen of artery and venous lumen form path, for blood circulation, complete hemodialysis; After hemodialysis completes, lumen of artery and venous lumen are therefrom cut off by inflation by sacculus, thus prevent contacting blood air setting from forming blocking, extend the service life of hemodialysis pipe; Simultaneously the groove of lumen distal and projection can reinforce the connection between body and the person, prevent body from coming off.
