However, during the operation, how to safely and stably fix the umbilical vein catheter in the correct position has always been a challenge. The traditional method is to use medical tape to fix the catheter to the skin. However, this method often faces the problems of unstable fixation, easy displacement, skin irritation and difficulty in maintaining the fixation effect. The displacement of the catheter may lead to the loss, blockage or even complete removal of the catheter, which may have a serious impact on the treatment of the newborn. Utility Model Content

[0003] In view of the above problems, the purpose of the present utility model is to provide an umbilical cord fixator for umbilical vein catheterization of newborns, so as to solve the problems raised in the above background technology.

[0004] To achieve the above purpose, the utility model adopts the following technical solution: an umbilical cord fixer for umbilical vein catheterization of a newborn, comprising an abdominal band, a through hole is opened on the abdominal band, an air bag ring, a pipeline fixer, a gel layer, a Velcro and an adhesive layer are arranged on the abdominal band, and the Velcro and the adhesive layer are bonded and connected, the air bag ring is located at the through hole, an air nozzle is arranged on the air bag ring, the pipeline fixer is composed of a base, a fixing ring, a splint and a non-slip rubber pad, and a pull block is arranged on the fixing ring and a card slot is opened, and a tooth portion for being stuck in the card slot is set on the splint.

[0005] The beneficial effects of the utility model are as follows: after the umbilical cord of the newborn is penetrated through the through hole to fix the belly band to the abdomen of the newborn, it is only necessary to fill the air bag ring with gas through the air nozzle to expand it, so that the stump of the umbilical cord can be squeezed and closed, and the umbilical venous catheter located at the inner end of the umbilical cord can be initially fixed. At the same time, the pipeline fixer can further fix the position of the active end of the umbilical venous catheter, thereby increasing the stability of catheter fixation and preventing the risk of displacement, loss, blockage or derailment of the catheter.

[0006] In order to facilitate the fixing of the abdominal belt, the umbilical cord is exposed:

[0007] As a further improvement of the above technical solution: the through hole is opened in the middle of the belly band.

[0008] The beneficial effect of this improvement is that, by opening the through hole, when the belly band is fixed to the abdomen of the newborn, the umbilical cord can pass through the through hole and be exposed to the outside world.

[0009] To facilitate the initial fixation of the umbilical venous catheter at the inner end of the umbilical cord:

[0010] As a further improvement of the above technical solution: the airbag ring is arranged on the outer ring of the through hole at the top end of the belly band.

[0011] The beneficial effect of the present improvement is as follows: through the establishment of the airbag ring, when an external inflation and deflation mechanism is used to connect the air nozzle, the airbag ring can be inflated and deflated; when gas is filled into the airbag ring to expand it, the airbag ring can wrap the umbilical cord and squeeze the umbilical cord stump to bring the umbilical cord stump together, thereby making it possible to initially fix the position of the umbilical venous catheter at the inner end of the umbilical cord, thereby preventing the use of a suture needle to sew the umbilical cord to initially fix the position of the umbilical venous catheter at its inner end, which is not only cumbersome and inconvenient, but also prone to the risk of needle stick injuries.

[0012] In order to prevent the belly band from shifting and increase the comfort and safety when wearing the belly band:

[0013] As a further improvement of the above technical solution: the gel layer is arranged at the bottom end of the abdominal band.

[0014] The beneficial effect of the present improvement is as follows: by establishing a gel layer, and the gel layer is made of an antibacterial gel material, when the polyethylene film covering layer adhered to the gel layer is removed and the belly band is fixed to the abdomen of the newborn, the gel layer contacts the skin of the newborn, which can increase the friction coefficient due to its certain viscosity, thereby preventing the belly band from sliding and displacing with the activities of the newborn and causing pulling on the catheter; at the same time, because of its certain antibacterial effect, the comfort and safety of wearing the belly band can be increased.

[0015] To help you put the belly band on your newborn's abdomen:

[0016] As a further improvement of the above technical solution: the Velcro is arranged near the edge of one side of the bottom end of the belly band, and the adhesive layer is arranged on the other side of the top end of the belly band.

[0017] The beneficial effect of this improvement is that after the belly band is placed on the abdomen of the newborn, the Velcro can be attached to the adhesive layer at a suitable distance to adapt to the circumference of the newborn, thus completing the wearing operation of the belly band on the abdomen of the newborn.

[0018] To increase the stability of the umbilical vein catheter during fixation:

[0019] As a further improvement of the above technical solution: the pipeline fixer is arranged at the top of the belly band on one side of the airbag ring, and the fixing ring and the splint are both arranged at the top of the base located on the belly band, and the anti-slip rubber pad is arranged on the inner wall of the fixing ring.

[0020] The beneficial effect of this improvement is that by providing the anti-skid rubber pad on the inner wall of the fixing ring, when the umbilical vein catheter is located at the inner end of the fixing ring for fixation, the anti-skid rubber pad contacts the umbilical vein catheter, which can increase the friction coefficient and enhance the stability of the umbilical vein catheter when it is fixed, thereby preventing the umbilical vein catheter from being easily displaced, blocked or falling out after being pulled.

[0021] To facilitate the adaptation of the umbilical venous catheter size, the umbilical venous catheter is fixed in position:

[0022] As a further improvement of the above technical solution: the number of the slots is several, and the slots are equidistantly arranged on the outer wall of the movable end of the fixed ring, and the teeth are arranged on the upper part of the splint near the fixed ring end.

[0023] The beneficial effect of this improvement is that by inserting the movable end of the fixing ring into the gap between the fixing ring and the splint, the teeth are locked in the slots at a suitable distance according to the size of the umbilical vein catheter, so that the fixing ring opening can be closed and the umbilical vein catheter can be fixed in position.

[0024] In order to facilitate the movement of the movable end of the fixed ring:

[0025] As a further improvement of the above technical solution: the pulling block is arranged on the outer wall of the fixing ring at the other end of the clamping groove away from the edge of the movable end of the fixing ring.

[0026] The beneficial effect of this improvement is that, by setting up the pulling block, it is convenient to pinch the pulling block to drive the movable end of the fixed ring to move. BRIEF DESCRIPTION OF THE DRAWINGS
