Description

Collection device of internal arteriovenous fistula pjncture needle

Technical Field

The application relates to the field of blood purification equipment, in particular to a collection device of an arteriovenous internal fistula puncture needle.

Background

The maintenance hemodialysis is a main kidney replacement treatment means for patients with end-stage renal diseases, the arteriovenous fistula is a recommended vascular access for the patients with the maintenance hemodialysis, a puncture needle needs to be used for performing hemodialysis operation during dialysis treatment, the arteriovenous fistula puncture needle has the characteristics of large size, difficulty in destroying and the like, and after treatment is finished, the correct treatment of the puncture needle after use has important significance for preventing puncture needle injury, environmental blood pollution and safety of medical care personnel and patients.

At present, after a puncture needle for arteriovenous internal fistula is pulled out, four treatment modes are mainly adopted: firstly, the sharps box is directly discarded after the needle is pulled out, the occurrence probability of needle stick injuries can be effectively reduced when the sharps box is placed in the shortest time after the needle is pulled out, but the sharps box needs to be placed nearby and is generally placed under a treatment vehicle clinically, sight line shielding is easy to cause, the treatment of puncture needles is not facilitated, when the sharps box is placed under a bed, the sharps box in one bed possibly needs to be sealed when the sharps box does not reach 3/4 within the specified time, and the cost is increased; secondly, using the portable sharps box after pulling out the needle: the current portable sharps boxes are used together in dialysis care packs and are disposable, relatively costly and therefore not widely used in clinics; thirdly, after the needle is pulled out, the cap is covered by one hand and is thrown into the sharps box, the cap is covered by one hand by an auxiliary tool, otherwise the risk of needle stick injury is increased, nursing staff can fix the needle cap by using adhesive tapes as the auxiliary tool, but the fixation is unstable and the operation is inconvenient; and fourthly, the puncture needle with the needle returning device is adopted, so that the method avoids the covering of the cap by one hand, but the cap is required to be separated and placed in the sharps box, the cost and the operation time are increased, and certain limitation exists.

In conclusion, the four treatment methods after the arteriovenous internal fistula puncture needle is pulled out have the following defects: clinical cost and operating time have been increased, can't use widely in clinic, lack firm appurtenance and fix the needle cap and realize that the singlehanded is turned over again, and the naked needle goes into sharp ware box and can increase the needle stick and hinder the risk, causes environmental blood pollution.
