A device for assisting in the rapid placement of umbilical arterial and venous catheters

Abstract

This invention relates to an auxiliary device for rapid umbilical artery and vein catheterization, comprising an upper rigid ring, a lower rigid ring, a notch, telescopic hooks, and a support tube. The telescopic hooks are self-adjusting and extendable, hidden within the tube when closed and protruding when open. After the operator cuts the umbilical cord, the device is placed on the cord, and the three telescopic hooks quickly secure the cord, ensuring clear exposure of the surgical site, maintaining tension, and providing rigid support to the cord. This invention, through a rapid auxiliary device for umbilical artery and vein catheterization, reduces the number of operations required by medical personnel, allowing for quick and successful procedures by a single medical staff member. It improves the first-time success rate of umbilical artery and vein catheterization, reduces arterial and venous injury and infection from the umbilicus, and facilitates the promotion of umbilical artery and vein catheterization in primary hospitals.

Description

Technical Field

[0001] This utility model relates to the field of rapid umbilical artery and vein catheterization, and in particular to an auxiliary device for rapid umbilical artery and vein catheterization. Background Technology

[0002] The umbilical cord is a relatively soft tissue with insufficient rigidity, which means that more than two people are needed to perform umbilical artery and vein catheterization. Poor surgical site exposure can easily lead to slippage of the umbilical artery and vein catheters during the procedure. If the catheterization technique is not good, it may take multiple attempts to succeed, thereby increasing the risk of damage to the umbilical artery and vein and infection from the umbilical region.

[0003] Therefore, there is a lack of an auxiliary device for rapid umbilical artery and vein catheterization, which provides a simple and convenient operating platform interface for neonatal umbilical artery and vein catheterization, reduces the catheterization operation time, and improves the success rate. Utility Model Content

[0004] The purpose of this invention is to address the problems in the prior art by proposing an auxiliary device for rapid umbilical artery and vein catheterization.

[0005] An auxiliary device for rapid umbilical artery and vein catheterization includes an upper rigid ring, a lower rigid ring, a notch, a telescopic hook, and a support tube;

[0006] The notch positions of the upper rigid ring and the lower rigid ring are parallel, and three telescopic hooks are equidistantly arranged inside the upper rigid ring. The upper and lower rigid rings are connected by a support tube.

[0007] Furthermore, an auxiliary device for rapid umbilical artery and vein catheterization is provided, wherein the upper rigid ring and the lower rigid ring are circular in shape, the upper rigid ring has a diameter of 5 cm, and the lower rigid ring has a diameter of 8 cm.

[0008] Furthermore, in an auxiliary device for rapid umbilical artery and vein catheterization, the upper rigid ring and the lower rigid ring are respectively welded to the support tube.

[0009] Furthermore, in an auxiliary device for rapid umbilical artery and vein catheterization, the height difference between the upper and lower rigid coils is 2.5 cm.

[0010] Furthermore, an auxiliary device for rapid umbilical artery and vein catheterization, wherein the length of the notch is 2mm.

[0011] Furthermore, an auxiliary device for rapid umbilical artery and vein catheterization, wherein the switch of the auxiliary device controls the extension and retraction of a telescopic hook.

[0012] The beneficial effects of this utility model are as follows: An auxiliary device for rapid umbilical artery and vein catheterization, with the notch positions of the upper and lower rigid rings parallel, and three telescopic hooks equidistantly arranged inside the upper rigid ring, and the upper and lower rigid rings connected by a support tube, reduces the number of operations required by medical personnel, allowing one medical personnel to operate quickly and successfully, improving the one-time success rate of umbilical artery and vein catheterization, reducing arterial and venous damage and infection from the umbilicus, and facilitating the promotion of umbilical artery and vein catheterization in primary hospitals. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of an auxiliary device for rapid umbilical artery and vein catheterization.

[0014] In the diagram: 1-Upper rigid ring, 2-Lower rigid ring, 3-Notch, 4-Telescopic hook, 5-Support tube. Detailed Implementation

[0015] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0016] As attached Figure 1 As shown, an auxiliary device for rapid umbilical artery and vein catheterization includes an upper rigid ring 1, a lower rigid ring 2, a notch 3, a telescopic hook 4, and a support tube 5.

[0017] The notch 3 of the upper rigid ring 1 is parallel to the notch 3 of the lower rigid ring 2. Three telescopic hooks 4 are equidistantly arranged inside the upper rigid ring 1. The upper rigid ring 1 and the lower rigid ring 2 are connected by a support tube 5.

[0018] The purpose of notch 3 is to facilitate the removal of the device after successful tube placement.

[0019] Furthermore, in an auxiliary device for rapid umbilical artery and vein catheterization, the upper rigid ring 1 and the lower rigid ring 2 are circular in shape, the diameter of the upper rigid ring 1 is 5cm, and the diameter of the lower rigid ring 2 is 8cm.

[0020] Furthermore, in an auxiliary device for rapid umbilical artery and vein catheterization, the upper rigid ring 1 and the lower rigid ring 2 are respectively welded to the support tube 5.

[0021] Furthermore, in an auxiliary device for rapid umbilical artery and vein catheterization, the height difference between the upper rigid coil 1 and the lower rigid coil 2 is 2.5 cm.

[0022] Furthermore, an auxiliary device for rapid umbilical artery and vein catheterization, wherein the length of the notch 3 is 2mm.

[0023] Furthermore, an auxiliary device for rapid umbilical artery and vein catheterization is provided, wherein the switch of the auxiliary device controls the extension and retraction of the telescopic hook 4.

[0024] The telescopic hook 4 can extend and retract on its own and adjust its distance. When closed, the telescopic hook 4 is hidden inside the tube, and when open, it will extend out of the tube. After the operator cuts the umbilical cord, the device is placed on the umbilical cord and the umbilical cord is quickly fixed by the three telescopic hooks 4, so that the surgical surface is clearly exposed, a certain tension is maintained, and a certain rigid support is given to the umbilical cord.

[0025] This solution utilizes an auxiliary device for rapid umbilical artery and vein catheterization. The notches on the upper and lower rigid rings are parallel, and three telescopic hooks are equidistantly positioned inside the upper rigid ring. The upper and lower rigid rings are connected by a support tube. This reduces the number of medical personnel required for the procedure, allowing for quick and successful operation by a single medical staff member. It improves the one-time success rate of umbilical artery and vein catheterization, reduces arterial and venous injury and infection from the umbilicus, and facilitates the promotion of umbilical artery and vein catheterization in primary hospitals.
