Description

A butterfly wing needle fixing device with a card slot

technical field

The utility model relates to the field of medical equipment, in particular to a butterfly-wing needle fixing device with a clamping groove.

Background technique

The infusion port is a closed infusion device that is completely implanted into the human body. It belongs to the field of medical devices. It includes the catheter part with the tip located in the superior vena cava and the injection seat embedded under the skin. Because the catheter end is in the large vein, it can be quickly diluted. The drug concentration can avoid stimulation and damage to the blood vessel wall. Compared with ordinary intravenous infusion, it reduces the chance of hardening of the arteries, and also reduces the pain of repeated needle sticking because the blood vessels cannot be found. Therefore, this infusion method is more and more popular with patients. Because there are many types and models of butterfly-wing needles and infusion ports, during clinical infusion, the gap between the butterfly-wing needle and the infusion port base will be large, making them easy to loosen. In order to ensure the connection between the butterfly-wing needle and the infusion port For fixation, currently, gauze is placed under the butterfly wing needle, and then the butterfly wing needle is fixed on the patient with adhesive tape. However, due to the patient's movement and other reasons, the butterfly wing needle may shift or even come out, resulting in fluid leakage. If the needle tip of the butterfly wing needle comes out completely, it will cause a needle stick injury.

In order to achieve the above purpose, the technical scheme adopted by the present utility model is: it comprises a bonding part and a fixing part, and the bonding part is sequentially provided with an adhesive layer and a dressing layer from bottom to top, and the adhesive layer can be adhered to the skin. , the dressing layer is required to be soft and skin-friendly, the upper end of the dressing layer is provided with a limit groove, the size of the limit groove is adapted to the needle wing of the butterfly wing needle, and the bottom of the limit groove is provided with a clamping groove; The lower end of the card plate is provided with a clip adapted to the card slot, and the clip is inserted into the card slot to install the card plate on the dressing layer. .

Further, the lower end of the card plate is provided with a positioning column, and the positioning column is inserted into the through hole from above the needle wing of the butterfly wing needle to further ensure that the butterfly wing needle will not be displaced.

Further, in order to adjust the position of the positioning column, the lower end of the card plate is provided with a chute, the upper end of the positioning column is provided with a sliding seat that is tightly fitted with the sliding groove, and the outer wall of the sliding seat is fitted with the sliding groove, which requires a larger size. It takes force to push the positioning column.

Further, the applicator is a transparent one, so as to facilitate the observation of the skin condition at the puncture site of the butterfly wing needle of the infusion port.

The beneficial effects of the utility model are as follows: the needle wing and the needle body of the butterfly-wing needle are placed in the limiting groove, and then the clamping plate should be closed above the butterfly-wing needle, thereby fixing the position of the butterfly-wing needle and avoiding the displacement of the butterfly-wing needle.

1. The lower end of the card board is provided with a positioning column to further ensure that the butterfly wing needle will not be displaced.

2. The application is transparent, which is transparent and visible, which is convenient for timely observation of the infusion port and the punctured skin.

3. Simple and convenient, one-time use, no need to bother with gauze pads; all sterile materials, low risk of cross-infection; soft material, fit with the uneven infusion port below, no skin, good patient compliance .
