Background technology
Hemodialysis often adopts traditional metal puncture to puncture for artery and vein vascular, and is fixed and carries out dialysis treatment, and this metal puncture pin is only for a hemodialysis, and the damage caused blood vessel is larger.Metal puncture pin, at Ink vessel transfusing, is easily attached on blood vessel, affects blood flow, easily produces oozing phenomenon in site of puncture.
In blood dialysis, the puncture arm of patient must not move, and causes inconvenience to patient, and patient comfort degree is poor.General patients with renal failure needs hemodialysis 2-3 time weekly, and metal puncture pin repeated puncture causes inevitable damage to patient vessel, brings misery to patient simultaneously, also therefore becomes heavier to the workload of clinical nurse.
Summary of the invention
The present invention be directed to the weak point that above-mentioned existing issue exists, a kind of solution is proposed, substituted metal puncture needle is carried out with flexible catheter, by the trocar or Sai Dingge puncture method, a kind of flexible catheter is sent into blood vessel, conduit has higher blood compatibility can in long-time stable indwelling blood vessel, flexible catheter can bend with the bending of blood vessel, do not hinder patient activity, can treat for chronic hemodialysis, re-start puncture when avoiding hemodialysis again, patient stays Ink vessel transfusing at treatments period flexible catheter can not affect patient's daily life.
For achieving the above object, the technical solution adopted in the present invention is:
A kind of arterial-venous dialysis puts pipe, mainly be made up of conehead, conduit, double-vane needle handle, lock-on connection and helmet, conehead is connected with conduit welding, conduit, double-vane needle handle and lock-on connection are bonding to be successively connected, helmet is removably tightened on lock-on connection, and conduit has one or more hole on one end body of conehead.
A kind of arterial-venous dialysis disclosed by the invention is put in the embodiment of pipe, and conehead and conduit adopt soft medical grade material to make, and medical grade material is polyurethane.
A kind of arterial-venous dialysis disclosed by the invention is put in the embodiment of pipe, and the hardness of the hardness ratio conduit of conehead is less, and conehead is more soft than conduit.
A kind of arterial-venous dialysis disclosed by the invention is put in the embodiment of pipe, and conehead is provided with tapering.
A kind of arterial-venous dialysis disclosed by the invention is put in an embodiment of pipe, and the shape in the one or more holes of conduit on one end body of conehead is identical with size.
A kind of arterial-venous dialysis disclosed by the invention is put in another embodiment of pipe, the shape in the one or more holes of conduit on one end body of conehead with vary in size.
The invention also discloses the using method that a kind of arterial-venous dialysis puts pipe, comprise the following steps:
Step one: helmet is screwed off from lock-on connection;
Step 2: tube cavity preliminary filling normal saline is put to dialysis, and dialysis is put pipe and be placed in normal saline moistening;
Step 3: conehead and conduit are sent into blood vessel and stayed Ink vessel transfusing for a long time for hemodialysis by the trocar or Sai Dingge puncture method;
Step 4: double-vane needle handle and skin are close to or by fixing subsides, double-vane needle handle are fixed to skin.
Wherein, conehead and conduit are admitted in blood vessel, can be bending with blood vessel twisting, and blood flows through the one or more holes on catheter tube.
Wherein, in step 2, conehead and conduit indwelling time in the blood vessel can reach one month to half a year.
beneficial effect
It is simple that a kind of arterial-venous dialysis disclosed by the invention puts tubular construction, manufacturing process is simple, to human body Wicresoft, and safety and stability, its can Preserving time in the blood vessel, do not affect the activity of patient, avoid misery and risk that each dialysis puncture blood vessel brings, alleviate because of the blood vessel injury caused that punctures, avoid inconvenience and risk that metal puncture pin brings, improve the safety of hemodialysis, reduce the workload of nurse simultaneously, improve the comfort level of patient.
Accompanying drawing explanation
