Description

Auxiliary clamp for non-invasive umbilical vein catheter fixation

technical field

The utility model relates to an umbilical vein catheter auxiliary fixing device, in particular to a non-invasive umbilical vein catheter fixing auxiliary clip.

Background technique

Critically ill infants, premature infants, especially very low birth weight infants, are prone to serious diseases such as respiratory distress syndrome, asphyxia, infection, and necrotizing enterocolitis, and often cannot obtain sufficient nutrition from the gastrointestinal route for a period of time after birth. A large amount of drug therapy and intravenous nutrition are needed; this kind of children has the characteristics of thin and tender skin, thin and hidden blood vessels, which not only brings difficulties to venipuncture, but also makes it difficult to meet the requirements of continuous intravenous infusion. The umbilical vein cannula for intravenous administration can make the medicine solution reach the newborn's body quickly, so as to achieve the purpose of rapid rescue and treatment.

The fixation of the umbilical vein catheter in the prior art is invasive to the child, that is, the method of surgical purse-string suture is used to fix the catheter, the premature umbilical vein is not filled, and the umbilical cord is twisted and rotated, the umbilical cord is thin, or the umbilical cord is edematous, etc. , a slight deviation during the operation will cause suture failure or mistaken puncture of the blood vessel, and it is difficult to master the ligation strength of the silk thread. The incidence of catheter-related complications is greatly increased.

Contents of the invention

The technical problem to be solved by the utility model is: to provide a non-invasive umbilical vein catheter fixation auxiliary clip, which can be used for non-invasive fixation of the neonatal umbilical vein catheter, and solves the above-mentioned prior art due to the use of A series of problems brought about by the invasive method of umbilical vein catheter fixation.

The technical solution to solve the above technical problems is: a non-invasive umbilical vein catheter fixation auxiliary clip, including an auxiliary clip body composed of a left half clip and a right half clip hinged through pin shafts, and the rear part of the auxiliary clip body is a left handle and a right handle , an elastic reset mechanism is arranged between the left handle and the right handle, and the elastic reset mechanism includes a left elastic piece fixed on the left handle and a right elastic piece fixed on the right handle, the front end of the left elastic piece is provided with a protrusion, and the front end of the right elastic piece There is a groove, the protrusion of the left shrapnel is located in the groove of the right shrapnel, and the front end of the auxiliary clip body is a tapered pipe clip with a large upper part and a smaller lower part formed by the left clip and the right clip.

The inner diameter D1 of the small end of the tapered pipe clamp is 3-5 mm, the inner diameter D2 of the large end is 8-10 mm, and the height H is 14-16 mm.

Indwelling the umbilical vein catheter for a long time, retaining the drug delivery channel, ensuring the rescue of critically ill children, avoiding repeated venipuncture, and improving the success rate of rescue and the quality of life of premature infants and critically ill children. Using the utility model to apply the suture-free umbilical circle-silk thread umbilical vein catheter fixation technology has good social and economic benefits.

Using the non-invasive umbilical vein catheter fixation auxiliary clip of the utility model and applying the suture-free umbilical ring-silk umbilical vein catheter fixation technology reduces the technical requirements for neonatal umbilical vein catheterization, reduces the difficulty of operation, shortens the operation time, and makes the umbilical cord residual The end exposure time is shortened, and at the same time, it can effectively avoid vascular injury, reduce the occurrence of complications such as infection, local bleeding, and puncture of blood vessels, which is more conducive to the promotion of non-invasive umbilical vein catheterization technology in neonatology.

Below, the technical features of the non-invasive umbilical vein catheter fixation auxiliary clip of the present invention will be further described in conjunction with the accompanying drawings and embodiments.

Detailed ways

Embodiment 1: A non-invasive umbilical vein catheter fixation auxiliary clip, as shown in Figure 1-Figure 2, includes an auxiliary clip body 1 composed of symmetrical left half clips and right half clips hinged by pin shafts 5, the auxiliary clip body The rear part is a left handle 21 and a right handle 22, and an elastic return mechanism 4 is arranged between the left handle and the right handle. The elastic return mechanism includes a left elastic piece 41 fixed on the left handle and a right elastic piece fixed on the right handle. 42. The front end of the left shrapnel is provided with a protrusion 411, and the front end of the right shrapnel is provided with a groove 421. The protrusion of the left shrapnel is located in the groove of the right shrapnel. Large and small tapered pipe clamps 3 . The inner diameter D1 of the small end of the tapered pipe clamp 3 is 3-5 mm, preferably 4 mm, the inner diameter D2 of the large end is 8-10 mm, preferably 9 mm, and the height H is 14-16 mm, preferably 15 mm.

Utilizing the utility model, the umbilical vein catheterization operation can adopt the suture-free umbilical circle-silk umbilical vein catheter fixation method, and its specific operation steps are: the catheterization is performed under strict aseptic operation, and the vital signs of the patient are closely monitored during the operation Change, lead the umbilical vein filled with heparin solution through the valve core with tail wire. Insert the umbilical vein catheter into the umbilical vein. When inserting the umbilical vein catheter to the umbilical chakra, if there is resistance, it cannot be inserted forcibly, and it should be withdrawn slightly before inserting, so as not to injure the blood vessel wall. Insert the umbilical vein catheter 4-6cm, and the blood can be withdrawn smoothly outflow, and then use the tapered sleeve clamp of the present utility model to insert into the valve core, press the left handle and the right handle of the present utility model inwardly, so that the left clip and the right clip of the tapered sleeve clamp are opened outwards, so that the valve The core expands, and the tapered sleeve clamp is moved to the outside of the umbilical cord stump, and the tail wire is pulled to make the valve core move down from the tapered sleeve clamp to cover the root of the umbilical cord. At this time, the utility model can be removed. Insert the umbilical vein catheter under the guidance of the bedside B-ultrasound, make its front end stay at the junction of the right atrium and the inferior vena cava, tie the connecting rope on the catheter, wrap the silk-catheter with sterile transparent tape, and fix the umbilical vein catheter. Cover the umbilicus with sterile gauze. If there is no bedside B-ultrasound guidance, use blind insertion to the expected depth, and the bedside X-ray positioning is confirmed.

The utility model is one of the core technologies of suture-free umbilical circle-silk umbilical vein catheter fixation. Using the non-invasive umbilical vein catheter fixation auxiliary clip of the utility model and applying the suture-free umbilical circle-silk umbilical vein catheter fixation technology reduces the umbilical cord of newborns. The technical requirements for venous catheterization can reduce related complications, which is more conducive to the promotion of umbilical vein catheterization technology in neonatology.
