Description
Technical field
It can plant subcutaneous vascular access the utility model relates to one kind and puncture valve.Its design is long-term in single-needle two-cavity
Long term vascular access is subcutaneously established in the puncture closure valve implantation in hemodialysis catheter tail end connecting band silicon rubber Puncture and blocking face.
Background technique
Establishing effective vascular access is the prerequisite for carrying out haemodialysis, at present clinically common vascular access
Have: chronic hemodialysis conduit, self 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 disadvantages 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 access, and in China, hospital or other medical institutions are not
See and uses and report.
Summary of the invention
The utility model aim is to overcome the use of native valves access to damage excessive and the deficiencies in the prior art, provides
One kind can plant subcutaneous vascular access and punctures valve, can be used for a long time, damages and complication is less to help patient to establish one
And the vascular access of more convenient living nursing.
The concrete scheme for solving above-mentioned technical problem is as follows: can plant subcutaneous vascular access and punctures valve, including conduit connects
Connector, fastening nut, valve cavity seat, the silicone rubber for sealing and sealing cover that closure can be punctured.Specific structure and connection relationship are as follows:
The catheter connecting joint is socketed by fastening nut and the long-term tail end of conduit of haemodialysis, and catheter connecting joint and valve are empty
The connection of chamber seat, valve cavity seat are equipped with the silicone rubber for sealing that can puncture closure, can puncture the silicone rubber for sealing of closure equipped with close
Capping can plant subcutaneous vascular access and puncture valve and integrally be implanted into and subcutaneous establishes long term vascular access.
The sealing cover is covered on the puncture face of sealing surface silicon rubber in " mouth " font, and sealing cover passes through the spiral shell at 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 of medical embedded type silastic material, can puncture the sealing of closure
The puncture face of silicon rubber can meet puncture needle and puncture closure repeatedly.
The puncture face of the silicone rubber for sealing for puncturing closure can meet puncture needle and be punctured repeatedly more than 800 times.
The puncture face length of the silicone rubber for sealing for puncturing closure is 50mm.
The valve cavity seat is integrally in U-typed cylinder.
The puncture valve is in irregular roundness cylindricality, and puncture valve length is 50-80mm, whole to be embedded in subcutaneously.
The catheter connecting joint, fastening nut, valve cavity seat and sealing cover medical metallic titanium monoblock cast.
The prominent advantage of the utility model is:
1. can whole 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 influencing the haemodynamics to human body, the dirty burden of center of gravity is not added, not will lead to heart failure and cause pulmonary infection.
3. the sealing surface silicon rubber that can puncture closure can carry out multiple location, puncture repeatedly, extensive after being conducive to skin penetrating
It is multiple, it keeps using for a long time.
