Detailed Description

In order to explain the technical content, structural features, achieved objects and functions of the present invention in detail, the following embodiments are described in detail with reference to the accompanying drawings.

Referring to fig. 1-3, the utility model discloses an anti-slipping trocar, which comprises a stylet 1, a sleeve 2 and a connecting seat 3, wherein the top surface of the connecting seat 3 is provided with a sleeve groove 31 for placing the sleeve 2; the bottom surface of the connecting seat 3 is fixedly connected with a silica gel pad 32, and the bottom surface of the silica gel pad 32 is provided with an adhesive layer.

A containing groove 33 is formed in the side wall of the connecting seat 3, and an adhesive tape 34 is arranged in the containing groove 33; the tail end of the adhesive tape 34 is fixedly connected in the containing groove 33, and the adhesive surface of the adhesive tape 34 is arranged back to the silica gel pad 32.

Can be through having the silica gel pad of pasting the layer with the connecting seat temporarily connect on patient's skin, treat to put into the sleeve pipe groove at connecting seat top with the sleeve pipe after the puncture is accomplished, then utilize the adhesive tape to fix the sleeve pipe temporarily in the sleeve pipe groove, make things convenient for the nurse to do subsequent action. Since the position of the cannula is now relatively fixed, there is a risk that the trocar may slip when the nurse withdraws the core, especially when the nurse is wearing multi-layered gloves.

The width of the adhesive tape 34 is larger than one half of the length of the sleeve groove 31 and smaller than the length of the sleeve groove 31, and the length of the adhesive tape 34 is larger than the sum of the height of the connecting seat 3 and the width of the top surface of the connecting seat 3.

The width of the adhesive tape is set to ensure that the adhesive tape can effectively limit the sleeve in the sleeve groove in the using process and the operation of tearing off the adhesive tape and taking off the sleeve after use is not influenced; the length setting of adhesive tape guarantees that it is in the use, and the free end of adhesive tape can paste the opposite side in the connecting seat steadily to stability when guaranteeing the fixed sleeving.

As shown in fig. 4, in another embodiment of the present invention, the position of the adhesive surface of the adhesive tape 34 corresponding to the sleeve groove 31 is provided with a silica gel strip 35 corresponding to the shape of the sleeve groove 31 (i.e. the distance between the silica gel strip and the adhesive tape fixed end is equal to the sum of the distance a between the right edge of the sleeve groove and the right edge of the connecting seat top surface and the distance b between the accommodating groove and the connecting seat top surface, since the depth of the accommodating groove is limited in practical application, the adhesive tape fixed end and the length of the leaving accommodating groove are changed when the angle changes in the accommodating groove, the width of the silica gel strip 35 is smaller than the width of the sleeve groove 31, and the length of the silica gel.

The arrangement of the silica gel strip, on one hand, when the adhesive tape is used for fixing the sleeve, the silica gel strip can be used as a soft filler positioned between the adhesive tape and the sleeve, and the stability that the adhesive tape limits the sleeve in the sleeve is further increased; on the other hand is because the existence of silica gel strip for the sleeve pipe is not with the viscose surface direct contact of adhesive tape, drive the sleeve pipe and arouse patient's discomfort when avoiding getting the trocar to tear the adhesive tape.

The width of the accommodating groove 33 is greater than the width of the silica gel strip 35, and the depth of the accommodating groove 33 is greater than the thickness of the silica gel strip 35. The width and the depth of the containing groove are set, so that the adhesive tape with the silica gel strip can be folded and contained (similar to the sector of a folding fan) and then placed in the containing groove.

The viscose face of pasting layer and adhesive tape all is equipped with the one deck and leaves type paper, and the stickability of adhesive tape and silica gel pad can not destroyed when guaranteeing not using (there is the point of tearing that surpasss silica gel pad and adhesive tape from the type paper shaping, and the nurse of being convenient for wearing gloves on the one hand tears from type paper and conveniently pastes, and on the other hand makes things convenient for the nurse to draw the adhesive tape from the holding tank through tearing the point and draws out), makes things convenient for the antiskid to take off the storage and the transportation of trocar. The storage tank 33 is equipped with the paper strip of paper seal outward, and the paper strip of paper seal is arranged in the adhesive tape restriction that the folding was accomodate in the storage tank when storing the transportation, plays sealed warning's effect simultaneously: when the paper seal is broken, it indicates that the trocar may be used.

As shown in fig. 5, in another embodiment of the present invention, two parallel edges of the top surface of the connecting seat 3 and the sleeve groove 31 are processed by chamfering, so as to ensure the tightness when the adhesive tape is attached to the connecting seat, and correspondingly, the position of the silica gel strip is also adjusted correspondingly.

In addition, the top surface of silica gel pad also can be equipped with the layer of pasting of taking from type paper, treats the puncture and accomplishes the back, tears the type paper from the type paper at silica gel pad top, still can be used to the supplementary heparin cap of connecting in fixed sleeve needle end.

The working process of the utility model is as follows:

1. selecting blood vessels, pricking the tourniquet above the puncture point (near the heart end), and sterilizing with iodophor twice for drying;

2. tearing the outer package of the trocar, tearing the release paper on the bottom surface of the silica gel pad, sticking the connecting seat below the puncture point (far end), simultaneously drawing out the adhesive tape from the accommodating groove, and placing the adhesive surface upwards for later use after tearing the release paper;

3. a scalp needle of the infusion apparatus is connected with a cannula needle heparin cap, the air is exhausted, then a needle core is loosened, the blood vessel is directly punctured at an angle of 15-30 degrees above the blood vessel, and the needle is slowly inserted until the blood returns;

4. after the puncture is successful, the sleeve is placed into the sleeve groove by holding the Y-shaped interface of the sleeve with the left hand, and the sleeve is fixed in the sleeve groove along the connecting seat by the right hand;

5. after the cannula is fixed, the needle core is quickly withdrawn, and then the tourniquet and the infusion apparatus adjuster are loosened;

6. and finally, fixing the heparin cap and the pipeline between the heparin cap and the trocar on the upper surface of the silica gel pad.

In summary, the preferred embodiments of the present invention are only examples, and the scope of the present invention is not limited thereto, and all equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the specification are within the scope covered by the present invention.
