Description

An indwelling needle for easy fixation

technical field

The utility model relates to the technical field of medical supplies, in particular to an indwelling needle which is convenient for fixing.

Background technique

The components of the indwelling needle include a soft catheter or cannula that can be indwelled in the blood vessel and a stainless steel puncture guide core. When in use, the catheter and the needle core are punctured into the blood vessel together. When the catheter is completely inserted into the blood vessel, the needle core is withdrawn. , only the flexible catheter is left in the blood vessel for infusion therapy. The use of indwelling needles can reduce blood vessel damage caused by repeated punctures, reduce the pain of children, and enable timely and rapid intravenous administration, which is more convenient.

Existing indwelling needle generally is to directly fix indwelling needle on the patient's skin with adhesive tape after puncture indwelling, and the outer edge of the three-way infusion port on the indwelling needle main body is used to connect infusion tube to facilitate infusion. Since the indwelling needle can generally be left in place for 72-96 hours, this method of tape fixation is not only difficult to fix and stick the tape with one hand after the indwelling needle enters the skin when the indwelling needle is punctured. When the situation is frequent, the edge of the tape is easy to fly, and the casing of the indwelling needle is almost cylindrical. If the tape is loose and careless, it will drive the indwelling needle to move. After the indwelling needle moves out of the blood vessel, it will not only cause accidental damage to the surrounding tissues, but also Need to puncture again, very troublesome.

To sum up, it is necessary to propose an indwelling needle that is convenient for fixing to solve the above problems.

Utility model content

In order to solve the above-mentioned technical problems, the utility model provides an indwelling needle that is easy to fix. The indwelling needle that is easy to fix includes: an indwelling needle housing, an isolation plug is provided at the inner rear end, and an indwelling needle tube is arranged on the outside of the outer front end. , the indwelling needle tube is provided with a puncture needle, the rear end of the puncture needle is inserted into the indwelling needle housing, passes through the isolation plug and is fixedly connected with the needle handle cap, the front end of the needle handle cap is inserted into the indwelling needle housing, and the outer wall of the indwelling needle housing is provided with silica gel Both sides of the indwelling needle housing are uniformly provided with silicone sheets, the rear ends of the two silicone sheets are provided with pull rings, the bottom sides of the two silicone sheets are coated with a pressure-sensitive adhesive layer, and the pressure-sensitive adhesive layer There is a release paper on the sticker.

Wherein, the front end of the puncture needle at least partly passes through the indwelling needle tube, and the front end of the puncture needle is set on a 10-20 degree bevel, and the bevel is set upward, the indwelling needle tube is covered with an outer sleeve, and the indwelling needle tube and the front end of the puncture needle are both Set in the outer casing.

Wherein, the housing of the indwelling needle is connected with the liquid inlet tee, and a side hole is opened on the puncture needle in the connection.

Among them, the side of the two silicone sheets away from the indwelling needle housing is inclined downward in a slope shape. bottom side flush.

Wherein, the needle handle cap is connected with the handle.

Implementation of the utility model embodiment has the following beneficial effects:

This easy-to-fix indwelling needle is equipped with an integrally formed silicone sheet on the bottom and both sides of the indwelling needle shell. The soft silicone sheet can be attached to the patient's skin, hindering the indwelling needle from sliding after puncture, and is convenient for doctors and nurses to stick tape to fix. Improve the comfort of the patient; by opening a side hole on the rear end of the puncture needle, the side hole is connected with the liquid inlet tee, so that the blood can flow back quickly after the puncture needle penetrates the blood vessel, so as to judge whether the blood vessel is successfully penetrated; through A pull ring is set on the rear end of the silicone sheet, so that when the doctor finds that the blood does not flow back, which means a blood vessel puncture error, the entire indwelling needle tube and the puncture needle can be pulled out in time by pulling the pull ring, which can reduce the damage to the patient.
