Description

Butterfly wing needle fixing device with clamping groove

Technical Field

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

Background

The transfusion port is a closed transfusion device which is completely implanted into a human body, belongs to the field of medical instruments, and comprises a catheter part with the tip positioned in a superior vena cava and an injection seat which is embedded into the subcutaneous part, because the tail end of the catheter is positioned in a great vein, the concentration of a medicine can be quickly diluted, the stimulation and the damage to the blood vessel wall are avoided, the chance of hardening the blood vessel is reduced compared with the common venous transfusion, and the repeated needle pricking caused by the fact that the blood vessel can not be found is also reduced, so that the transfusion mode is more and more popular with patients. The butterfly wing needle and the infusion port are multiple in types and models, so that a gap between the butterfly wing needle and an infusion port base is large during clinical infusion, the butterfly wing needle and the infusion port base are easy to loosen, gauze is padded under the butterfly wing needle at present in order to ensure connection and fixation of the butterfly wing needle and the infusion port, and then the butterfly wing needle is fixed on a patient body by using adhesive tapes, but the butterfly wing needle can be displaced or even separated due to the movement of the patient and other reasons, so that liquid seeps under the skin and infection is caused seriously; if the needle tip of the butterfly wing needle is completely withdrawn, the needle stick injury can be caused.

SUMMERY OF THE UTILITY MODEL

The utility model aims at above problem, provide a butterfly wing needle fixing device with draw-in groove, can prevent that the butterfly wing needle from shifting.

In order to realize the above purpose, the utility model adopts the technical scheme that: the butterfly wing needle comprises a bonding part and a fixing part, wherein the bonding part is sequentially provided with a glue layer and a dressing layer from bottom to top, the glue layer can be bonded on skin, the dressing layer requires to be soft and skin-friendly, the upper end of the dressing layer is provided with a limiting groove, the size of the limiting groove is matched with a needle wing of the butterfly wing needle, and the bottom of the limiting groove is provided with a clamping groove; the fixing part comprises a clamping plate matched with the limiting groove and an application patch used for fixing, wherein a buckle matched with the clamping groove is arranged at the lower end of the clamping plate, and the buckle is inserted into the clamping groove so as to install the clamping plate on the application layer.

Furthermore, the cardboard lower extreme is provided with the reference column, and the reference column inserts in its through-hole from the needle wing top of butterfly wing needle to further ensure that butterfly wing needle can not shift.

Further, in order to adjust the position of the positioning column, the lower end of the clamping plate is provided with a sliding groove, the upper end of the positioning column is provided with a sliding seat tightly matched with the sliding groove, the outer wall of the sliding seat is attached to the sliding groove, and the positioning column can be pushed only by large force.

Furthermore, the application is transparent application so as to be convenient for observing the skin condition of the puncture position of the butterfly wing needle of the infusion port.

The utility model has the advantages that: the needle wing and the needle body part of the butterfly wing needle are placed in the limiting groove, and then the clamping plate is closed above the butterfly wing needle, so that the position of the butterfly wing needle is fixed to avoid the displacement of the butterfly wing needle.

1. The cardboard lower extreme is provided with the reference column to further ensure that the butterfly wing needle can not shift.

2. The application is transparent, and is transparent visual, conveniently in time observes infusion port and puncture skin condition.

3. The pad is simple and convenient, is disposable, and is not needed to be padded with gauze; the materials are all sterile materials, so that the risk of cross infection is low; the material is soft, the infusion port seat is attached to the uneven lower surface of the infusion port seat, the skin is not damaged, and the compliance of a patient is good.

Detailed Description

In order to make the technical solution of the present invention better understood, the present invention is described in detail below with reference to the accompanying drawings, and the description of the present invention is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention.

As shown in fig. 1-2, the specific structure of the present invention is: the adhesive part is sequentially provided with an adhesive layer 1 and a dressing layer 2 from bottom to top, before use, the upper end surface and the lower end surface of the adhesive part are covered with anti-sticking paper, the dressing layer 2 is made of a soft skin-friendly, breathable and water-absorbent material, so that sweat and the like can be adsorbed to maintain a relatively dry internal environment during use, such as a hydrocolloid dressing layer and the like, the upper end of the dressing layer 2 is provided with a limiting groove 3, the bottom of the limiting groove 3 is provided with a clamping groove 4, and meanwhile, the upper end of the dressing layer 2 is also reserved with a position for placing a needle body part of a butterfly wing needle; the fixing part comprises a clamping plate 5 matched with the limiting groove 3 and an application plate 6 used for fixing, the upper end face and the lower end face of the application plate 6 are also covered with anti-sticking paper before use, and a buckle 7 matched with the clamping groove 4 is arranged at the lower end of the clamping plate 5.

Preferably, the lower end of the clamping plate 5 is provided with a positioning column 8, and the height of the positioning column 8 is not higher than the thickness of the needle wing of the butterfly wing needle.

Preferably, 5 lower extremes of cardboard are provided with spout 9, 8 upper ends of reference column are provided with the sliding seat with spout 9 close-fitting, spout 9 adopts T type groove, dovetail isotructure to avoid reference column 8 to drop.

Preferably, the application 6 is a transparent application, such as a PICC transparent application.

The specific embodiment is as follows: tearing off the release paper on the adhesive layer 1, and then tightly adhering the adhesive layer 1 to the skin without leaving a gap between the two; then, the release paper on the dressing layer 2 is torn, the design of the release paper is the same as that of the existing indwelling needle application sticker, the release paper is torn from the middle to two sides, then the butterfly wing needle is clamped in the limiting groove 3, and then the clamping plate 5 is pressed into the limiting groove 3 to enable the buckle 7 to be buckled in the clamping groove 4; finally, a PICC transparent application is used to cover the skin with the radius exceeding the external diameter of the lower application layer 2 by at least five centimeters to the periphery by taking the puncture position of the butterfly wing needle as the origin to form a closed environment.
