Description
Technical field
This utility model relates to a kind of hemodialysis with implanted blood drainage pipe, belongs to technical field of medical instruments.
Background technology
Hemodialysis is the main treatment means of uremic patient.
And hemodialysis must be with outside the body inner blood lead body, in the blood input body after will purifying again after the blood dialysis machine is processed.The clinical blood dialysis generally will be carried out 3 ~ 4 times weekly.
Because the blood that hemodialysis requires to draw reaches certain flow rate, at least 200 ~ 300ml/min clinically takes the internal arteriovenous fistula operation mostly, sets up the blood vessel road, punctures and draws blood until carrying out internal fistula after the internal fistula maturation during in each dialysis.Because internal arteriovenous fistula might form the complication such as blood vessel infection, thrombosis, and can increase the heart burden, adds repeated localised puncture, brings great misery to the patient.And for the patient of original cardiac insufficiency, mostly take long-term dark Vein Tube to draw blood.Pipe easily occurs to infect and conduit is adherent but put for a long time, the problems such as Insufficience of blood flow, thereby can not become desirable dialysis with drawing the blood device.
Summary of the invention
This utility model aims to provide a kind of rational in infrastructure, clinically reuses continuously, and hemodialysis that can complication is with implanted blood drainage pipe, to overcome the deficiency of prior art.
This utility model realizes that the technical scheme of its purpose is:
A kind of hemodialysis is with implanted blood drainage device, and it comprises the implantation blood taking tube that can be connected with human vas, and the blood fairlead with implanting blood taking tube and connect perforation is used for preventing the chuck that blood flows out, terminal and chock plug; Described blood fairlead by the body inner segment of implant into body tissue and be in external section of the tissue outside each other one form; Described chuck and described blood fairlead external section is equipped mutually; External section each other one and mutually perforation of described terminal and blood fairlead; Described chock plug and terminal sealing attaching.
Can be understood by above given technical scheme, by surgical operation, after in the blood vessel (arteries) of this utility model implant into body tissue, under the effect of haemodialysis control unit, the blood of dialysis patient can be drawn the enforcement dialysis in body.And after dialysis finishes, in the normal saline ascending pipe, press again pipeline capacity heparin in sealing, then with chock plug and terminal sealing attaching, and after suitably wrapping up, just can when implementing dialysis, reuse next time.This utility model so uses again and again continuously, thereby has realized its purpose that will realize, the misery of having avoided repeated localised puncture to bring to patient.
This implanted blood drainage pipe does not change original tubular construction and the flow direction, human implantable shallow artery such as radial artery, femoral artery, and brachial artery etc., and flow back to heart without the short circuit blood flow, and do not increase the heart burden, diastolic dysfunction also can be used.
Owing to external pathogenic bacteria causes infection along blood fairlead intrusive body inner tissue, this utility model is also advocated, also comprises preventing with the tissue driving fit sleeve pipe of antibacterial intrusion tissue for fear of implant site; The outer surface of described sleeve pipe has numerous fine projections; And described sleeve pipe closely is sleeved on the body inner segment of blood fairlead.Because outer surface has the existence of the sleeve pipe of numerous projections, human body is combined closely by granulation tissue and described sleeve pipe, thereby blocked the passage that external antibacterial is invaded, the pipeline slippage has also been avoided in the infection of effectively having avoided described implant site to occur simultaneously.
After considering implantation blood taking tube implant into body blood vessel, the blood coagulation system of meeting exciting human has thrombosed risk, so this utility model carries out the heparin coating processing, heparin coating is located at the inner surface of implanting blood taking tube and blood fairlead, effectively to prevent thrombosis.
In view of blood of human body flows necessary smooth and easy in pipe, for fear of occuring, turbulent flow causes blood coagulation and blood vessel injury, this utility model is also advocated, the handing-over of described implantation blood taking tube and blood fairlead, it is the axis of implanting blood taking tube, and keep the monoclinic phase commissure of certain angle to connect between the axis of blood fairlead, and described angle is in 10 °～30 ° scopes, and implants the inside pipe wall that blood taking tube and blood fairlead connect the position and be rounding off.When clinical use this utility model, the entrance point of blood fairlead should be pointed to the upstream of human vas blood flow.Like this axis of blood flow fairlead with implant the blood taking tube axis and be under 10 °～30 ° the angle condition, enter the blood fairlead and by outside the lead body from the blood of human vas upstream is just can be smooth and easy accessible.Add and implant the inside pipe wall rounding off that blood taking tube and blood fairlead connect the position, just can effectively avoid causing owing to turbulent blood flow the situations such as blood coagulation.
In technique scheme, sleeve pipe described in the utility model is medical terylene sleeve pipe or medical nylon sleeve.This is that this utility model institute is preferred.But be not limited to this.Other and tissue have affinity and anaphylactoid material do not occur, and all are fine equally.And be laid in the projection of described sleeve surface, and preferably irregular distribution, its diameter is preferably less than 1.5mm, and it is highly preferably less than 2mm, to reduce it to the damage of tissue.When needs take out, but underwent operative is peeled off rear taking-up.。
In technique scheme, coating described in the utility model is heparin coating.But be not limited to this, other also is fine such as the anticoagulants such as rapamycin, anti-proliferative drug coating.
After technique scheme was implemented, it is rational in infrastructure that this utility model has, and can reuse for dialysis procedure repeatedly after implanting, and clinical hemodialysis is easy and simple to handle and reduce the characteristics such as patient suffering, is apparent.
