Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an umbilical vein catheter fixation device. Background Technology

[0002] Umbilical venous catheterization (UVC) is a medical technique that inserts a catheter into the inferior vena cava through the umbilical vein at the stump of the newborn's umbilical cord. It is used to establish intravenous access for critically ill newborns and premature infants to facilitate procedures such as intravenous infusion, drug administration, nutritional support, and blood sample collection. After successful UVC placement, the catheter needs to be secured. Currently, this is typically achieved by tying a bandage around the umbilical cord. However, controlling the bandage tension is difficult; excessive tension can cause excessive pressure on the umbilical cord, while insufficient tension can lead to the bandage dislodging. Furthermore, the catheter remains in place for a considerable period, requiring disinfection and cleaning of the area around it. This process necessitates loosening and re-tying the bandage, demanding high skill levels from medical personnel and is time-consuming. Utility Model Content

[0019] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms; these terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be called "second" information, and similarly, "second" information can also be called "first" information.

[0021] like Figure 1 , Figure 2As shown, this utility model discloses an umbilical vein catheter fixation device for fixing a catheter inserted into the umbilical vein to the umbilical cord. A preferred embodiment of this utility model's umbilical vein catheter fixation device includes a flexible band 1 and an elastic clip 2. The elastic clip 2 includes a first clip 21 and a second clip 22 arranged opposite to each other, forming a clamping space 200 between the first clip 21 and the second clip 22. The flexible band 1 is wrapped around the outer periphery of the umbilical cord and has a fixed end 11 and a tightening end 12. The fixed end 11 is connected to the side of the first clip 21 facing away from the second clip 22, and the tightening end 12 is clamped in the clamping space 200. Specifically, the tightening end 12 is wound along an arc path to the elastic clip 2, and the elastic clip 2 and the flexible band 1 enclose a binding hole 100 for inserting the umbilical cord. The elastic clip 2 clamps the tightening end 12. In use, after inserting the catheter into the infant's umbilical cord, the umbilical cord is threaded through the ligation hole 100. At this point, the ligation hole 100 has a relatively large diameter. After the umbilical cord is inserted, press the elastic clip 2 to loosen the tightening end 12. Then pull the tightening end 12 to adjust the tightness of the flexible band 1 on the umbilical cord. After adjustment, release the elastic clip 2. The elastic clip 2 will then hold the tightening end 12, maintaining tightness around the umbilical cord and preventing the catheter from dislodging. When disinfection or cleaning around the catheter is required, simply release the elastic clip 2 to loosen the flexible band 1. The operation is convenient and efficient.

[0022] In this embodiment, the elastic clamp 2 further includes an elastic pressure member; the first clamping plate 21 and the second clamping plate 22 are hinged at the middle, and a clamping space 200 is formed between the first end of the first clamping plate 21 and the first end of the second clamping plate 22; a binding hole 100 is formed between the first clamping plate 21 and the flexible band 1; the elastic pressure member connects the first clamping plate 21 and the second clamping plate 22 to drive the first end of the first clamping plate 21 and the first end of the second clamping plate 22 to clamp the tightening end 12.

[0023] Specifically, the elastic clamp 2 also includes a rotating shaft 23, which rotatably connects the middle of the first clamping plate 21 and the middle of the second clamping plate 22. The elastic pressure element is a torsion spring 24, which includes a helical part 241, a first torsion arm 242, and a second torsion arm 243. The helical part 241 is sleeved on the outside of the rotating shaft 23. The first torsion arm 242 is connected to one end of the helical part 241 and abuts against the first clamping plate 21. The second torsion arm 243 is connected to the other end of the helical part 241 and abuts against the second clamping plate 22. Under the elastic force of the torsion spring 24, the first clamping plate 21 and the second clamping plate 22 remain clamped. When a person presses the first clamping plate 21 and the second clamping plate 22, the distance between the first end of the first clamping plate 21 and the first end of the second clamping plate 22 increases, thereby increasing the clamping space 200 and contacting the clamping end 12. At this time, the diameter of the binding hole 100 increases.

[0024] In this embodiment, the width of the first clamping plate 21 is greater than the width of the flexible strip 1, the width direction of the flexible strip 1 is parallel to the width direction of the first clamping plate 21, the connection position of the fixed end 11 on the first clamping plate 21 is located near its first end, that is, at the first end of the first clamping plate 21, and a part of the first clamping plate 21 and the flexible strip 1 located on the arc path enclose the binding hole 100.

[0025] In this embodiment, the flexible band 1 has a first side facing the binding hole 100 and a second side facing away from the binding hole 100. The first side has a plurality of slots 13 spaced apart along the length of the flexible band 1, and the second clamping plate 22 has a first protrusion 211 for inserting into the slots 13. When the first clamping plate 21 and the second clamping plate 22 clamp the flexible band 1, the first protrusion 211 is engaged in one of the plurality of slots 13, thereby improving the clamping firmness of the elastic clamp 2 on the tightening end 12. The slots 13 are serrated, further increasing the clamping firmness of the elastic clamp 2 on the tightening end 12.

[0026] In this embodiment, multiple first protrusions 211 are provided, and the multiple first protrusions 211 are arranged at intervals along the length direction of the second clamping plate 22. Specifically, the interval between two adjacent first protrusions 211 is the same as the interval between two adjacent slots 13. When the elastic clamp 2 is in the clamping state, at least one first protrusion 211 matches and engages with one slot 13, further improving the clamping firmness of the elastic clamp 2 on the tightening end 12.

[0027] Furthermore, the first clamping plate 21 has a first limiting hole in its middle. Along the length of the first clamping plate 21, the rotating shaft 23, the first limiting hole, and the fixed end 11 are arranged sequentially at intervals, and the tightening end 12 passes through the first limiting hole. Specifically, the first limiting hole extends through the thickness direction of the first clamping plate 21, and the tightening end 12 passes through the first limiting hole. The wall of the first limiting hole serves to prevent the flexible band 1 from sliding in the width direction of the first clamping plate 21, further improving the firmness of the elastic clamp 2 in holding the flexible band 1.

[0028] Furthermore, the first clamping plate 21 has a second protrusion 221 on the side facing away from the second clamping plate 22, and the second protrusion 221 has a second limiting hole extending along the length direction of the first clamping plate 21; in the length direction of the first clamping plate 21, the first limiting hole is arranged between the second protrusion 221 and the fixed end 11, and the tightening end 12 passes through the first limiting hole and the second limiting hole. The tightening end 12 that passes through the first limiting hole returns to the side of the first clamping plate 21 facing away from the second clamping plate 22. If the length of the tightening end 12 protruding outside the first limiting hole is too long, it may cause discomfort to the child when it touches the child's skin. In this embodiment, the tightening end 12 that protrudes outside the first limiting hole is inserted into the second limiting hole. The second limiting hole plays a role in limiting and guiding the tightening end 12, guiding the end of the tightening end 12 away from the flexible band 1, and realizing the function of storing the excessively long tightening end 12.

[0029] To avoid skin allergies and discomfort caused by the first splint 21, in this embodiment, the material of the first splint 21 is medical-grade silicone. The flexible band 1 is also made of medical-grade silicone, but the difference is that the hardness of the flexible band 1 is lower than that of the splint.

[0030] In summary, the umbilical vein catheter fixation device of this utility model includes a flexible band 1 and an elastic clip 2. The elastic clip 2 includes a first clip 21 and a second clip 22 arranged opposite to each other, forming a clamping space 200 between the first clip 21 and the second clip 22. The flexible band 1 is wrapped around the outer periphery of the umbilical cord. The flexible band 1 has a fixed end 11 and a tightening end 12. The fixed end 11 is connected to the side of the first clip 21 facing away from the second clip 22. The tightening end 12 is clamped in the clamping space 200. The elastic clip 2 clamps the tightening end 12. The elastic clip 2 can clamp the tightening end 12, which makes it easy to loosen the flexible band 1 or adjust the tightness of the flexible band 1, thereby facilitating the disinfection and cleaning of the catheter.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
