Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an umbilical vein catheterization device for critical newborn birth. Background Technology

[0002] A search of existing Chinese patent document CN221692474U reveals a neonatal umbilical vein catheterization method, comprising an umbilical vein cannula. One end of the umbilical vein cannula is equipped with a connector for injecting medication with a syringe, and the other end is a cannula that can be punctured and inserted into the umbilical vein. Furthermore, the umbilical vein cannula is equipped with an umbilical cord clamp for securing the umbilical cord, thus preventing the umbilical vein cannula from dislodging after puncture. This method simultaneously provides the functions of cannula puncture and umbilical cord fixation to prevent dislodging. Moreover, in emergency situations, only the packaging needs to be unpacked once, and the clamp only needs to be used once for fixation, making the operation simple and reliably saving precious rescue time.

[0003] Umbilical vein catheterization is a common medical procedure used to administer intravenous fluids, blood, and medications to premature infants and newborns. It involves inserting a catheter into the newborn's umbilical vein to deliver nutrients and medications. Umbilical vein catheterization is typically performed at the neonatal bedside using sterile catheters and appropriate techniques. Current methods for neonatal umbilical vein catheterization have the following problems: 1. Critically ill newborns often have no breathing or heartbeat after birth, so resuscitation is a race against time. It is necessary to administer adrenaline or even saline to expand the body volume within minutes of birth. Currently, adrenaline can be administered via endotracheal infusion, umbilical vein infusion, or intraosseous infusion; peripheral intravenous access is not recommended (due to the lack of effective blood circulation).

[0004] 2. Intratracheal administration: Intratracheal administration refers to the instillation of epinephrine into the endotracheal tube after successful endotracheal intubation. Critically ill newborns often have severe lung diseases, and the drug diffuses slowly. Therefore, the dosage for intratracheal administration (0.5-1 ml / kg) is higher than that for intravenous administration (0.1-0.3 ml / kg). However, this can cause some degree of tracheal obstruction, affecting lung ventilation and resulting in minimal therapeutic effect. Furthermore, it is not possible to administer saline for volume expansion via the endotracheal tube.

[0005] 3. Intraosseous cavity drug administration: Intraosseous cavity drug administration requires professional equipment and technical support. Operators must undergo rigorous training and master the correct puncture techniques and operating procedures. Otherwise, the risk of complications such as infection, extravasation, and fracture may increase.

[0006] 4. Umbilical vein drug administration: The umbilical vein is the most direct central venous access in a newborn, enabling rapid delivery of medications into the circulatory system. Umbilical vein catheterization is relatively easy and has a high success rate in neonatal resuscitation. However, in clinical practice, the process from opening the umbilical vein puncture kit and inserting the catheter to securing it is time-consuming, potentially delaying neonatal resuscitation.

[0014] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0015] In the attached diagram, all identical reference numerals refer to the same components.

[0016] Example 1 Reference Figure 1 One embodiment of this utility model is a device for umbilical vein catheterization for critical newborns, comprising a puncture tubing 1, a puncture bevel end 2 on the bottom surface of the puncture tubing 1, a drug delivery end 3 on the top surface of the puncture tubing 1, and a plurality of annular protrusions 4 sequentially arranged on one side surface of the drug delivery end 3, a heparin cap 5 on the top surface of the drug delivery end 3, a movable ring 6 at the bottom end of the heparin cap 5, and the heparin cap 5 and the movable ring 6 are connected and fixed by a loop 7.

[0017] The puncture tubing 1, the puncture bevel end 2, and the drug delivery end 3 are integrated into one piece, and the puncture tubing 1 and the drug delivery end 3 are connected in the middle. The drug delivery end 3 and the annular protrusion 4 are fixedly connected, and the annular protrusion 4 are arranged vertically in sequence, with the annular protrusion 4 having a protrusion width of 1cm.

[0018] The drug delivery end 3 and the heparin cap 5 are connected by threads, and the top of one side surface of the drug delivery end 3 and the inner surface of the heparin cap 5 are provided with corresponding threads.

[0019] The drug delivery end 3 and the movable ring 6 are movably connected. The middle part of the movable ring 6 is circularly hollowed out and is fitted into the top of the drug delivery end 3 for connection and fixation. The loop ring 7 is U-shaped and the two ends of the loop ring 7 are respectively connected to the heparin cap 5 and the movable ring 6 for fixation.

[0020] Specifically, its structure comprises a puncture tubing 1, a puncture bevel end 2, a drug delivery end 3, an annular protrusion 4, a heparin cap 5, a movable ring 6, and a loop 7, forming an umbilical vein catheterization device for critically ill newborns. The puncture tubing 1 is 5cm long and has the same rigidity as an indwelling needle, facilitating successful insertion into the umbilical vein. The puncture bevel end 2 facilitates puncture, the drug delivery end 3 facilitates subsequent drug administration, and the annular protrusion 4 allows for securing and fixing of the residual umbilical cord after puncture by wrapping silk around it, preventing the device from slipping. The annular protrusions 4 are arranged in multiple vertical rows with a 2mm spacing, ensuring that the inner wall of the residual umbilical cord end is wrapped around the annular protrusions 4 for a certain degree of stability. The device features a limiting mechanism to reduce slippage and enhance safety. The heparin cap 5 facilitates repeated punctures for drug administration, such as adrenaline, saline, and sodium bicarbonate. When not in use, the heparin cap 5 seals the end of the administration terminal 3 to prevent bacterial infection. It is also easy to open during administration, as the movable ring 6 is integrated with the administration terminal 3 and can rotate on its surface, facilitating opening and closing. A loop 7 connects the heparin cap 5 and the movable ring 6 at both ends, securing the heparin cap 5 to the administration terminal 3 and preventing loss. This simple overall structure and easy operation of the emergency neonatal umbilical vein catheterization device reduce the time required for use and effectively lower the risk of complications.

[0021] Working principle: After the umbilical cord is cut at birth, open the packaging of the emergency neonatal umbilical vein catheterization device, rotate the heparin cap 5 to connect the drug delivery end 3 to the syringe. During the puncture, insert the entire puncture tubing 1, including the puncture bevel end 2 and the drug delivery end 3, into the umbilical vein, ensuring the residual umbilical cord wraps around the puncture tubing 1 up to the annular protrusion 4 on the surface of the drug delivery end 3. After aspirating and observing blood, remove the syringe, replace the heparin cap 5, and use sutures to secure the residual umbilical cord around the annular protrusion 4, completing the puncture. Later, the heparin cap 5 can be repeatedly opened and the syringe connected to the drug delivery end 3 for repeated punctures and drug delivery.

[0022] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
