Description

A trocar anti-off protective sleeve

technical field

The present invention relates to a trocar used for medical infusion, in particular to a trocar shedding-preventing protective sleeve.

Background technique

At present, when hospitals give patients infusions, they often use trocars and scalp needles in combination. The existing trocars and scalp needles are fixed by adhesive tape, so the connection between the trocar and the scalp needle of the infusion set is often used. Shedding occurs; and fixing the scalp needle with adhesive tape is not easy to stick firmly and is not easy to remove and replace, and it is not beautiful.

Contents of the invention

The object of the present invention is to solve the above-mentioned technical problems and provide a trocar anti-off protection cover. This structure makes the connection between the trocar and the scalp needle of the infusion set firmly fixed, not easy to fall off, and has better use effect. the

In order to solve the deficiencies of the above-mentioned technical problems, the technical solution adopted by the present invention is: a trocar anti-off protective cover, including a scalp needle and a trocar connected to the infusion set, and the needle head of the scalp needle is inserted into the trocar Inside, there is also a transparent sleeve, and the two ends of the transparent sleeve are respectively fixed with limit tubes. The needle is set in the transparent sleeve through the opening, and the hose connected with the scalp needle passes through the limit tube at the upper end of the transparent sleeve to connect with the infusion set. One end of the trocar is set in the transparent sleeve through the opening, and the other end passes through the transparent sleeve. The limit tube at the lower end of the transparent sleeve extends out, and the transparent sleeve is also provided with a fixing band, which closes the opening on the transparent sleeve.

Beneficial effects of the present invention:

In the present invention, by setting a transparent sleeve with an opening, and setting limit tubes at both ends of the transparent sleeve, the trocar and the scalp needle are effectively prevented from falling off, and the fixation is firm; secondly, the transparent design is convenient for observation; it is convenient for fixing and replacement Scalp needle; single reusable. the

Marks in the figure: 1. scalp needle, 2. trocar, 3. transparent sleeve, 301, opening, 4. limit tube.

Detailed ways

As shown in the figure, a trocar anti-off protection cover includes a scalp needle 1 and a trocar 2 connected to the infusion set. The needle part of the scalp needle 1 is inserted into the trocar 2, and a transparent cannula is also provided. 3. Both ends of the transparent sleeve 3 are respectively fixed with limiting tubes 4. The aperture of the limiting tube 4 is smaller than the aperture of the transparent sleeve 3. Both the transparent sleeve and the limiting tubes at both ends are provided with openings 301. The scalp needle 1 Set in the transparent sleeve 3 through the opening, the flexible pipe connected with the scalp needle 1 passes through the limit tube at the upper end of the transparent sleeve 3 and is connected with the infusion set, so the upper end of the scalp needle 1 is controlled by the limit tube at the upper end of the transparent sleeve Fixed, one end of the trocar 2 is arranged in the transparent sleeve 3 through the opening, and the other end passes through the limit tube at the lower end of the transparent sleeve 3 and stretches out. The transparent sleeve 3 is also provided with a fixing belt, which will The opening 301 on the transparent sleeve is closed and the trocar and the scalp needle connected with the trocar are fixed in the transparent sleeve. This structure makes the connection between the trocar and the scalp needle of the infusion set firm and not easy to fall off. The effect is better. the
