Background
With the development of medicine, catheter therapy in clinical application becomes more and more popular, such as implantable drug delivery devices, central venous catheterization through peripheral venipuncture, indwelling needles and the like, which not only brings great convenience to doctors, but also relieves pain for patients. However, the treatment of catheters after insertion and insertion may be associated with a number of risks. For example, thrombus formation within, on and around the catheter, in turn, triggers catheter occlusion and a series of inflammation and tissue necrosis within the body. In addition, pathogenic bacteria and/or fungi grow after catheter insertion, resulting in bloodstream infection, fever, and the like. Both of these conditions may further lead to potential health hazards for the patient. Therefore, such surgery often requires sealing after the surgery is completed, i.e. injection of an anticoagulant (e.g. heparin) or antibacterial (e.g. taurolidine) solution.
In general, the tube sealing liquid used for tube sealing needs to be prepared on site, and after the preparation is finished, the tube sealing liquid is drawn out of a propelling catheter or an indwelling needle by a needle tube. Such problems exist as follows: the flow is various, the conventional tube sealing operation is up to 18 steps, the labor intensity of medical personnel is increased, and the risk of secondary pollution of tube sealing liquid exists; when the needle tube is used for injection, acupuncture is easy to occur, and the infection risk of medical staff is increased; after the tube sealing is finished, the catheter is completely sealed by adopting a locking cone and the like, so that the infection risk of a patient is further increased.
In general, the current catheter lock approach forces the practitioner to choose to lock the catheter and then re-lock the catheter, and practice of the present invention is directed to overcoming the above problems.
