Description
Background technique
The utility model belongs to medical instruments field more particularly to a kind of hemodialysis arteriovenous fistula puncture needle.
At present, haemodialysis is one of acute or chronic renal failure kidneys of patients Replacement Therapy.It passes through will be internal
Blood drainage is to external, through one by the dialyzer that is formed without several hollow fibres, blood electricity similar with concentration containing body
Electrolyte solution dialyzate carries out mass exchange inside and outside hollow fibre one by one, through disperse/convection current, and it is useless to remove intracorporal metabolism
Object maintains electrolyte and acid-base balance；Moisture excessive in vivo is removed simultaneously, and will be by the entire mistake of the blood recovery purified
Journey is known as haemodialysis.Patient needs using arteriovenous fistula puncture needle in hemodialysis, and existing arteriovenous fistula puncture needle exists
When specifically used, usually fix syringe needle using medical adhesive tape, but the general hemodialysis time needs several hours, the time compared with
It is long, patient sometimes accidentally act situations such as syringe needle that just may make loosens on hand, influence entire hemodialysis treatment.
Utility model content
The utility model is for deficiency present in background technique, and a kind of hemodialysis arteriovenous fistula puncture needle provided.
A kind of hemodialysis arteriovenous fistula puncture needle of the utility model, including syringe needle, outer tube and infusion tube, housing
The front end of pipe is installed with syringe needle, two sides are respectively and fixedly provided with the needle wing, tail end is equipped with interface, and the front end of infusion tube is equipped with and interface
The tail end of the plug, infusion tube that are used cooperatively is equipped with plug, and set is filled with fixed device and flow-stopping clip on the infusion tube,
Fixed device is that the velcro bandage being used cooperatively is installed on the both ends of arc plate, the fixed use of the top middle portion of arc plate
In the casing of interspersed infusion tube, the top side of arc plate sets and is all provided on the needle wing fixed there are two lateral bolt, two sides
There is the jack being used cooperatively with bolt.
As the preferred of the utility model, the top of the arc plate is equipped with platform part, and casing is fixed in platform part,
The side of casing is installed with infusion tube and is fixed plate in platform part, is fixed in the middle part of plate and is equipped with triangle and arches upward portion.
As the preferred of the utility model, the interface is placed in the back upper place of outer tube main body.
As the preferred of the utility model, the syringe needle is equipped with the needle cap being used cooperatively.
A kind of hemodialysis arteriovenous fistula puncture needle of the utility model, simple structure and reasonable design, it is easy to use and operate,
Stability is high, can reuse, the medical waste for advantageously reducing medical care cost, avoiding the wasting of resources and generation solves
There are single to fix by medical adhesive tape for existing arteriovenous fistula puncture needle, the problem of stability difference, and when use can be avoided hemodialysis
When patient situations such as causing syringe needle to loosen because of acting on hand, ensure that the fairness of entire hemodialysis treatment.
Detailed description of the invention
