Background

The artificial liver technology is a new medical technology which uses the blood purification technology to temporarily replace the liver function, so that the liver cells can be recovered and regenerated, and finally the life of a patient can be saved. It adopts the mode of "changing blood" to remove toxin from patient's blood plasma, i.e. the blood plasma containing toxin is changed into healthy blood plasma, and every time about 50% of blood plasma of whole body is changed. The artificial liver technology developed at present includes: in order to meet the requirement of blood flow, deep vein catheterization is required, and internal jugular vein catheterization is a good way for providing various therapeutic medicines and can reduce the stimulation of medicines to peripheral veins, so jugular vein catheterization is preferred in the clinical practical operation of artificial liver.

The exposed part of the common jugular vein catheterization in most existing hospitals can be covered and fixed on the body of a patient by using a transparent adhesive film, so that the vein catheterization can be kept for several months, and two blood vessels (blood vessels are blood catheters which respectively correspond to the vein vessel and the artery vessel of the patient) can be directly externally connected to the vein catheterization when the artificial liver is done next time, so as to form a blood flow path again. However, in the clinical practical operation, the two blood vessels are easily bent due to the movement of the patient, so that the dialysis blood flow is not smooth and the dialysis is not sufficient; in addition, the two blood path tubes are easy to fall off from the vein catheterization tube due to the movement of the patient, the risk of unplanned catheter drawing is increased, and if the two blood path tubes fall off from the vein catheterization tube, the patient can bleed greatly and even be endangered to life; therefore, in light of the above-mentioned problems, it is desirable to design a device that can fix both the blood line and the intravenous line and avoid disconnection of the connection between the blood line and the intravenous line.
