Description
Technical field
The present invention relates to a kind of implantable subcutaneous vascular access to puncture valve.Its design is in single-needle two-cavity chronic blood
The puncture closure valve implantation in dialysis catheter tail end connect band silicon rubber Puncture and blocking face subcutaneously establishes long term vascular path.
Background technology
It is the prerequisite for carrying out haemodialysis to establish effective vascular access, at present clinically common vascular access
Have：Chronic hemodialysis conduit, autologous or graft internal arteriovenous fistula etc..But equal existing defects：Infection, blood easily occur for long-term conduit
Bolt, hemadostewnosis etc.；Internal arteriovenous fistula aggravates the shortcomings of heart burden easily causes heart failure, pulmonary infection.The New Blood now designed
Long-term conduit connection of dialysing punctures closure valve implantation and subcutaneously establishes long term vascular path, and in China, hospital or other medical institutions are not
See and use and report.
The content of the invention
Present invention aims to overcome that the use of native valves path damages excessive and the deficiencies in the prior art, there is provided a kind of
Implantable subcutaneous vascular access punctures valve, with help patient establish one can long-term use of, damage and complication it is less and
The vascular access of more convenient living nursing.
The concrete scheme for solving above-mentioned technical problem is as follows：Implantable subcutaneous vascular access punctures valve, including conduit connects
Joint, clamp nut, valve cavity seat, the silicone rubber for sealing and closure that closure can be punctured.Concrete structure and annexation are：
The catheter connecting joint is socketed by clamp nut and the long-term tail end of conduit of haemodialysis, and catheter connecting joint is empty with valve
Chamber seat connects, and valve cavity seat is provided with the silicone rubber for sealing that can puncture closure, can puncture the silicone rubber for sealing of closure provided with close
Capping, implantable subcutaneous vascular access puncture valve, which is integrally implanted into, subcutaneously establishes long term vascular path.
The closure is covered on the puncture face of sealing surface silicon rubber in " mouth " font, the spiral shell that closure passes through four angles
Silk fastening compressing all around completes seal request in sealing surface silicon rubber.
The silicone rubber for sealing for puncturing closure is made up of medical embedded type silastic material, can puncture the sealing of closure
The puncture face of silicon rubber can meet that puncture needle punctures closure repeatedly.
The puncture face of the silicone rubber for sealing for puncturing closure can meet that puncture needle punctures more than 800 times repeatedly.
The puncture face length of the silicone rubber for sealing for puncturing closure is 50mm.
The valve cavity seat is in integrally U-typed cylinder.
The puncture valve is in irregular roundness cylindricality, and it is 50-80mm to puncture valve length, overall to be embedded in subcutaneously.
The catheter connecting joint, clamp nut, valve cavity seat and closure medical metallic titanium monoblock cast.
The advantages of present invention is prominent is：
1. can integrally embedding upper arm it is subcutaneous, it is easy to use, do not influence to live, reduce catheter-related Infections: Clinical Study, thrombus, blood vessel
Narrow incidence.
2. not influenceing the haemodynamics to human body, the dirty burden of center of gravity is not added with, heart failure will not be caused to trigger pulmonary infection.
3. can puncture the sealing surface silicon rubber of closure can carry out multiple location, puncture repeatedly, be advantageous to extensive after skin penetrating
It is multiple, keep using for a long time.
Brief description of the drawings
Fig. 1 is the structural representation that implantable subcutaneous vascular access of the present invention punctures valve.
In figure mark for：Catheter connecting joint 1, clamp nut 2, valve cavity seat 3, can puncture closure sealing surface silicon rubber 4,
Closure 5.
Embodiment
Technical scheme is described further below by way of drawings and examples.
As shown in figure 1, implantable subcutaneous vascular access of the present invention punctures valve, including catheter connecting joint 1, fastening
Nut 2, valve cavity seat 3, the sealing surface silicon rubber 4 and closure 5 of closure can be punctured.Specific connected mode is as follows：
Catheter connecting joint 1 is socketed by clamp nut 2 and the long-term tail end of conduit of haemodialysis, and catheter connecting joint 1 is empty with valve
Chamber seat 3 connects, and valve cavity seat 3 is provided with the sealing surface silicon rubber 4 that can puncture closure, can puncture the sealing surface silicon rubber 4 of closure
Closure 5 is provided with, implantable subcutaneous vascular access puncture valve, which is integrally implanted into, subcutaneously establishes long term vascular path.
Four angle fastened by screw of the closure 5, closure 5 are covered in the closing that can puncture closure in " mouth " font
On the puncture face of face silicon rubber 4.The sealing surface silicon rubber 4 that closure 5 can puncture closure by screw compressing completes seal request.
The sealing surface silicon rubber 4 for puncturing closure is made up of medical embedded type silastic material, can puncture closure
The puncture face of sealing surface silicon rubber 4 can meet that puncture needle punctures closure repeatedly, and puncture face length is 50mm.The envelope of closure can be punctured
Closing the puncture face of face silicon rubber 4 can meet that puncture needle punctures more than 800 times repeatedly.
