Description

Novel arteriovenous internal fistula needle disposal box

Technical Field

The invention relates to the technical field of medical instruments, in particular to a novel arteriovenous internal fistula needle disposal box.

Background

Hemodialysis is one of the main treatment modes of patients in the chronic kidney disease uremia period, 80 percent of patients adopt arteriovenous internal fistula as a blood vessel access for dialysis, and the patients need to perform arteriovenous internal fistula puncture 2-3 times per week in a hospital, so that extracorporeal circulation is established, and the smooth performance of hemodialysis is ensured. Compared with a vein infusion puncture needle, the arteriovenous internal fistula puncture needle has the characteristics of being thick and long, and the like, when medical waste is treated, adverse events such as sharp injury, blood splashing in the puncture needle and the like are easy to occur, the hidden danger of blood-borne cross infection exists, and the health of doctors and patients is harmed.

At present, there are three main ways for treating an arteriovenous internal fistula needle, the first way is to separate the internal fistula needle from a hemodialysis pipeline by bare hands, throw the internal fistula needle into a sharps box, and throw the internal fistula needle into a medical garbage bag for centralized treatment; the second is that after the internal fistula needle is separated, the single hand is provided with a cap for resetting, and then the needle is thrown into a medical garbage bag for centralized treatment; and the third is that after the internal fistula needle is separated, the internal fistula needle is put into a disposable internal fistula needle collecting box and then is thrown into a medical garbage bag for centralized treatment. The first method is that the internal fistula needle is directly placed into a sharps box, which is easy to cause the defects of sharp injury and blood spill; in the second method, although the cap returning operation is carried out by one hand, the original cap of the internal fistula needle is smaller, and the defects of low execution rate and time consumption exist; in the third method, the internal fistula needle collecting box is not fixed, two hands are needed for operation, and the internal fistula needle is not fixed in the human body placing clamp groove, so that time and labor are wasted, and the risk of sharp injury is still caused.

Disclosure of Invention

In order to solve the problems, the invention discloses a novel arteriovenous internal fistula needle disposal box which not only can effectively fix an internal fistula needle placed in a sharps box, but also can realize the fixation of a single-hand and single-needle placement, and ensures the safety while improving the operation efficiency and convenience.

The specific scheme is as follows: the utility model provides a novel box is dealt with to arteriovenous internal fistula needle for accomodate internal fistula needle, its characterized in that: the disposable self-locking type disposable diaper comprises a box body and a box cover which are hinged with each other, wherein the box body is of a cuboid structure, a rectangular accommodating groove is formed in the middle of the top surface of the box body downwards, a rectangular accommodating pad is fixed at the bottom of the rectangular accommodating groove, two left and right internal fistula needle clamping grooves are formed in the top surface of the rectangular accommodating pad, the internal fistula needle clamping grooves are formed by needle tube grooves and tail fin grooves, the two internal fistula needle clamping grooves are arranged in a central symmetry mode about the center of the rectangular accommodating pad, two left and right symmetrical rotating accommodating grooves are further formed in the middle of the top surface of the rectangular accommodating pad, the left and right rotating accommodating grooves correspond to and are communicated with the left and right needle tube grooves respectively, a self-locking piece is arranged above the rotating accommodating grooves, two supporting blocks which are symmetrically arranged front and back are arranged at the notch of the rotating accommodating grooves, the cross section of the self-locking piece is in an inverted T shape and is formed by a first rectangular plate which is horizontally arranged and a second rectangular plate which is vertically arranged, the utility model discloses a box body, including box body center, first rectangular plate, support piece, rectangle place pad, magnet piece, self-locking piece, the both sides middle part rotates with two support pieces around with respectively and is connected around first rectangular plate, and its one side bottom of keeping away from the box body center is taken and is leaned on the rectangle and place to stack up, the top surface center department that the pad was placed to the rectangle is equipped with and supplies the second rectangular plate to rotate the magnet piece that leans on after, the rectangle is placed and is filled up and lean on position department with taking of first rectangular plate and inlay and be equipped with the magnet piece, self-locking piece is magnetic metal self-locking piece.

As a further improvement of the invention, the right side of the top surface of the box body is hinged with the box cover.

As a further improvement of the invention, the rectangular placing pad is a hard sponge rectangular placing pad.

The invention has the beneficial effects that: not only can effectively fix the internal fistula needle put into in the edge tool box, can also realize that single-hand single needle is put into fixedly, when promoting operating efficiency and convenience, has ensured the security.
