Description
Technical field
The utility model belongs to the field of medical instrument technology, more particularly to a kind of hemodialysis catheter that can be punctured.
Background technique
Currently, the prior art commonly used in the trade is such that
Blood purification technology refers to the general name of the various methods for continuously or discontinuously removing excessive in vivo moisture, solute etc.,
We are often called haemodialysis in daily life.The method of blood purification includes renal replacement therapies, blood perfusion, is immunized
Absorption, Endotoxin adsorption and plasma exchange etc..Each blood purification mode all respectively has feature, and respectively be suitable for various disease or
Various disease state.But no matter which type of blood purification, it is necessary to first establish effective venous channel, also known as blood is logical
Road is drawn the blood of patient's body from arterial end, is input in human body by vein end again after purging in vitro is handled.Therefore
Establishing effectively unobstructed blood access is the primary condition for realizing blood purification.
Haemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy.It is by drawing internal blood
Flow to it is external, through one by the dialyzer that forms without several hollow fibres, blood electrolyte similar with concentration containing body is molten
Liquid (dialyzate) carries out mass exchange inside and outside hollow fibre one by one, through disperse/convection current, remove intracorporal metabolic waste,
Maintain electrolyte and acid-base balance；Moisture excessive in vivo is removed simultaneously, and will be by the whole process of the blood recovery purified
Referred to as haemodialysis.Existing hemodialysis catheter does not have retention device when being punctured in patient body on the outside of conduit, it is not easy to
Paracentesis depth is grasped, dialysis-effect is influenced when too shallow, when too deep, increases the pain of patient, while also reducing the work of doctor
Make efficiency, and the closing of existing conduit is all that switch control is carried out by the buckle of kneading, this buckle after fixation, is led
Both sides of the edge can not be fixed too close inside pipe, be easy to cause bacterium to enter, pollute to catheter interior.
In conclusion problem of the existing technology is:
(1) there is no retention device on the outside of existing hemodialysis catheter, it is not easy to grasp paracentesis depth；
(2) existing catheter switch control buckle is easy to lead in use, catheter interior both sides of the edge can not be fixed too close
It causes bacterium to enter, catheter interior is polluted.
Summary of the invention
In view of the problems of the existing technology, the utility model provides a kind of hemodialysis catheter that can be punctured.
The utility model is realized in this way a kind of hemodialysis catheter punctured is provided with puncture needle；
Puncture needle tail end has been connected through a screw thread conduit, and integrated molding has multiple convex on the outside of puncture needle and catheter proximal end
Rise, being glued on the outside of conduit has air bag, and conduit is divided into blood vessel out on rear side of air bag and into blood vessel, out blood vessel and into blood vessel tail end all
It is socketed with connector.
The utility model is provided with protrusion, and vascular wall can be prevented too tight, so that the through-hole on the outside of puncture needle and conduit is stifled
Plug, influences to dialyse, and puncture needle tail end is connect by screw thread with conduit, can split placement, and storage is convenient；It is provided with air bag, it can
To play buffer function when being punctured, prevent piercing too deep, conduit, which is pierced into rear gasbag, may also function as the work of the protection to wound
With preventing infected wound.
Further, it is connected with newel inside connector, the knob in newel and outside is cementing, and newel center offers
Through-hole.
The connector of the utility model uses rotational communication mode, compared to traditional kneading buckle can effectively pre- bacteriological protection into
Enter, preventing from accidentally touching leads to buckle flick, highly-safe.
Further, blood vessel and fixed patch has been sticked into blood vessel two sides out.
The utility model will go out blood vessel and separately fix into blood vessel, fixation, when preventing from fixing simultaneously, after side is unclamped
Drive the other side that can not also fix.
Further, puncture needle tip is round blunt shape tip.
The utility model can prevent from puncturing vascular wall in puncture process by round blunt shape tip puncture needle, reduce meaning
Outer generation.
