Description

Technical Field

[0001] The invention relates to a compressor for preventing PICC catheterization from causing malposition of the internal jugular vein, and belongs to the technical field of medical devices. Background Art

[0002] Peripherally inserted central catheter (PICC) is mainly used for patients who need medium- and long-term infusion and infusion of irritating drugs. It has been widely used in clinical practice for patients undergoing chemotherapy for tumors, critically ill patients who need long-term infusion of irritating drugs, and patients in neurosurgery with poor venous conditions and relatively long treatment cycles. It is currently one of the safest infusion tools. The 2016 version of the guidelines of the American Infusion Nursing Society pointed out that the tip of the PICC catheter should be located at the superior vena cava-atrium junction (CAJ) between the superior vena cava and the right atrium or the lower segment of the superior vena cava near the CAJ. However, due to differences in the patient's physical condition, condition, and vascular condition, catheter malposition is a common complication during PICC catheterization, especially internal jugular vein malposition. Domestic literature reports that the incidence of internal jugular vein malposition is 3.3%-12.3%. If the catheter is not repositioned in time or is not repositioned successfully after being misplaced into the internal jugular vein, it may cause a series of complications, such as phlebitis, catheter blockage, venous thrombosis, etc.

[0003] At present, the main method used clinically to reduce internal jugular vein malposition is internal jugular vein occlusion. The traditional internal jugular vein occlusion method is that when the tip of the catheter is sent to the shoulder joint, the patient's head is tilted to the puncture side, and the lower jaw is close to the shoulder before the catheter is sent. Patients have certain difficulties in cooperation, especially when the patient is nervous during catheterization, and it is often difficult to keep the chin close to the shoulder. Even if the chin is as close to the shoulder as possible, for thin patients, the entrance of the internal jugular vein is still in a hollow state, and there is still a certain probability of catheter malposition. Other researchers have tried to use ultrasound probes to compress the internal jugular vein to reduce internal jugular vein malposition, but it requires the cooperation of another PICC specialist nurse or a nurse with ultrasound capabilities, resulting in a waste of manpower costs. In view of the limitations of the above methods, there is an urgent need for a compressor to prevent PICC catheterization internal jugular vein malposition to fundamentally solve the problem.

[0061] This embodiment provides an operation method of the device of the present invention, and the specific steps are as follows:

[0062] First, evaluate the patient who needs PICC catheterization and evaluate the body shape, and select the appropriate compression column based on this; then evaluate the neck circumference and determine the position where the elastic band 4 and the button 5 are combined. In principle, it is 2-4 cm longer than the normal neck circumference, which can not only play a fixing role, but also avoid discomfort to the patient caused by excessive tightness. Put the disposable protective coat 7 on the entire compressor. Finally, wear the compressor on the patient's neck and ensure that the selected compression column is facing the internal jugular vein. When the PICC is placed, insert the catheter to 15 cm, and ask the patient to turn his head to squeeze the compression column. The built-in pressure sensor in the compression column can display the compression intensity, thereby preventing the PICC catheter from mistakenly entering the internal jugular vein. After the catheter successfully reaches the CAJ point, the catheter is placed, the compressor is removed from the patient's neck, and the disposable protective coat 7 is placed in a yellow garbage bag.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
