Detailed Description

The following detailed description of the preferred embodiments of the invention, which is to be read in connection with the accompanying drawings, forms a part of the invention, and together with the embodiments of the invention, serve to explain the principles of the invention and not to limit the scope of the invention.

When the existing medical trocar is fixed, the trocar needs to be fixed, generally a medical adhesive tape is adopted for fixing, and when the medical trocar is used, the adhesive tape needs to be repeatedly cut for fixing; the process operation is complicated, and the time waste is serious.

Example 1

The utility model discloses a medical trocar fixing patch, which is shown in figure 1.

The medical trocar fixing patch of the embodiment comprises: a first fixed patch 1 and a second fixed patch 2; and cut apart through easily tearing 3 between first fixed paster 1 and the fixed paster 2 of second.

Specifically, the second fixation patch 2 acts as an elongated membrane extending from the side of the trocar patch of the first fixation patch 1. Further, the first fixing patch 1 is used for adhering a needle head 6 of a fixing sleeve needle; the second fixed patch 2 is used for bonding a pipeline 7 for fixing a cannula needle. According to the difference of the position of the indwelling needle and the position of the pipeline, the medical trocar fixing patch of the embodiment can be directly used or torn at the easy-to-tear line 3.

Further, the lengths of the second fixed patch 2 and the first fixed patch 1 are determined according to the requirement; illustratively, the second fixation patch 2 is longer than the first fixation patch 1 (not shown).

Further, the adhesive is coated on the bottom side surfaces of the first fixing patch 1 and the second fixing patch 2, so that the adhesive fixing of the trocar can be realized.

Further, a plastic film is provided on the side of the first fixing patch 1 and the second fixing patch 2 coated with the adhesive, and the plastic film can be used by peeling off the plastic film.

In a specific embodiment of the present invention, the first fixing patch 1 is used for fixing the needle 6; when in use, the needle 6 of the indwelling trocar is stuck on a human body for fixation. The second fixed patch 2 is used for fixing the pipeline 7; when in use, the tube 7 of the indwelling trocar is stuck on the human body for fixation.

Furthermore, the connection between the second fixing patch 2 (i.e. the lengthened film) and the first fixing patch 1 (original film) is made into a tearable easy-to-tear line 3, i.e. the connection between the second fixing patch 2 and the first fixing patch 1 is realized by a point-break type point mark. In use, the first and

second patches

1, 2 may be torn/cut at the frangible line 3 for securing a needle 6 or tubing 7, respectively, as shown in figure 2.

Further, the design of the equal fillet of first fixed paster 1 and the fixed paster 2 of second has avoided the limit phenomenon of sticking up that the friction leads to.

Furthermore, the first fixing patch 1 is made of transparent material, so that whether the blood seepage phenomenon exists at the puncture position can be conveniently observed.

Because the difference of the vascular condition, the puncture position is different, and the infusion end has the fixed position different, the utility model discloses a fixed paster of medical trocar can be used in a flexible way, and side extension department is used for fixed infusion connector end pipeline 7, can accomplish the syringe needle 6 and the pipeline 7 that a paster just can fix the trocar like this, the utility model discloses a fixed paster of medical trocar and the cooperation of trocar one to one use, need not tailor the sticky tape of reel formula, convenient to use has saved the time, and is more firm and timely to trocar's fixed.
