[0001] This utility model relates to the field of medical device technology, specifically to a neonatal umbilical vein catheter fixation device. Background Technology

[0002] Umbilical vein catheterization is an important technique for treating critically ill newborns in the neonatal intensive care unit. In cases of low gestational age, low birth weight, need for advanced life support such as endotracheal intubation, or unsuccessful repeated peripheral venous punctures, UVC (umbilical vein catheterization) is a crucial treatment method, and UVC fixation is a very important step.

[0003] In the past, the fixation method used in the existing technology involved tying the tube with thick cotton thread, then tying it with purse-string sutures and surgical sutures, and finally fixing it to the abdominal skin with adhesive tape or transparent dressing. This method was quite complicated and often resulted in the tube slipping out or bleeding, which often forced the removal of the tube and the initiation of other tube placement methods, increasing the suffering of premature infants and the financial burden on families. Utility Model Content

[0004] The purpose of this invention is to provide a fixation device for neonatal umbilical vein catheterization, which solves the problem of the previous fixation method in the background art. The method involves ligating the catheter with thick cotton thread, then suturing it with purse-string sutures or surgical sutures, and finally fixing it to the abdominal skin with adhesive tape or transparent dressing. This method is complicated and often results in catheter slippage and bleeding, which often forces the removal of the catheter and the initiation of other catheterization methods, increasing the suffering of premature infants and the financial burden on families. The invention effectively solves the problem of catheter slippage and dislodgement by setting up a buckle component.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] The neonatal umbilical vein catheter fixation device includes two sets of connecting blocks. The front of each connecting block is provided with a buckle assembly, which is used to quickly clamp and fix the umbilical vein catheter. The buckle assembly is provided with an adjustment component inside, which is used to flexibly adjust the buckle structure range.

A silicone adjustment rod is installed on the left side of the rotating disk, and a silicone adjustment sleeve is provided on the outer side of the silicone adjustment rod. A flexible plate is installed on the left side of the silicone adjustment sleeve.

[0009] Preferably, a connecting piece is provided in the middle of the connecting block, and reinforcing pieces are installed on the outer sides of both ends of the connecting piece, the reinforcing pieces being located on the inner side of the connecting block.

[0010] Preferably, the inner side of the buckle frame is provided with a movable groove, and the movable groove is located on the outer side of the buckle plate.

[0011] Preferably, a shaft groove is provided on the inner side of the other end of the buckle frame, and two sets of movable discs are provided on the inner side of one end of the buckle frame, with pressing blocks installed on the top and bottom of the movable discs.

[0012] Preferably, the top and bottom of the other end of the buckle plate are equipped with a rotating shaft, and the rotating shaft is located inside the shaft groove. The top and bottom of the inner side of the buckle plate are respectively provided with two sets of sliding grooves.

[0013] Preferably, a combined bearing is provided on the outer side of the silicone adjusting rod, and the combined bearing is located on the inner side of the right end of the buckle plate. A limit post is installed at the end of the soft plate, and movable posts are installed at the top and bottom of the limit post.

[0014] Preferably, the end of the support spring is provided with a push plate, and the push plate is located inside the inclined buckle.

[0015] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0016] 1. This utility model, by installing a buckle assembly, uses a buckle frame to restrict the inner structure, while the movable groove restricts the buckle plate. The buckle plate can be flipped along the pivot to clamp the central recessed area. The buckle assembly is made of elastic rubber. After the insertion depth of the umbilical vein catheter is determined, the recessed area is fixed to the umbilical vein catheter, and the lower buckle is wrapped around the root of the umbilicus and then tightened. The upper buckle is wrapped around the umbilical vein catheter and then tightened. The corresponding scale is determined to prevent slippage. It can be fixed to the abdominal skin with adhesive tape or transparent dressing.
