Description

CVC/PICC pipe wash pipe, convenient utensil for tube sealing

Technical Field

The utility model relates to the technical field of medical nursing products, in particular to a convenient tool for flushing and sealing a CVC/PICC catheter.

Background

Along with the increase of the incidence rate of tumors and chronic diseases, the new ideas, new tools and new technologies of vein treatment are popularized, and vascular access devices such as vein catheters play an increasingly important role clinically. CVC and PICC provide vascular access for emergency, critical and oncological patients, and are widely used for purposes of intravenous therapy, fluid infusion, hemodynamic monitoring, parenteral nutrition therapy, and the like.

However, if the CVC/PICC is improperly maintained, complications associated with catheter-related blood flow infections, catheter blockage, and the like may occur. Catheter blockage is a common complication with the occurrence rate of 25% -38%, and once the catheter blockage occurs, the catheter is required to be thrombolytically or even drawn or replaced, so that treatment interruption can be caused, the hospitalization time and the medical cost of a patient are increased, the prognosis of the patient can be influenced, even the death rate of the patient is increased, in addition, as the catheter indwelling time is prolonged, the risk of CRBSI is increased due to improper operation, and compared with a single-cavity catheter, the frequency of a pipeline connected by a joint replacement is higher in the use process of the multi-cavity catheter, so that the probability of CRBSI is increased.

To avoid unplanned tube drawing, in performing CVC/PICC maintenance, effective tube flushing and tube sealing should be performed in addition to strictly following aseptic guidelines and operating according to operating specifications. The flushing pipe and the sealing pipe are key links for prolonging the service time of the catheter and reducing complications.

The inventor finds that in daily work, when the conventional syringe is used for flushing and sealing a CVC/PICC catheter, after a set amount of normal saline is pumped into the CVC/PICC catheter by using the syringe, the corresponding syringe is connected with the corresponding CVC/PICC catheter so as to push the pumped normal saline into the CVC/PICC catheter, and subsequently, the corresponding syringe is pulled out, the corresponding syringe is used for pumping heparin solution with the set amount, and the used syringe is connected with the corresponding CVC/PICC catheter again so as to push the pumped heparin solution with the set amount into the CVC/PICC catheter, so that the flushing and sealing operation of the CVC/PICC catheter is realized.

For the related operation process, the inventor feels very time and labor-consuming, needs to temporarily draw in the set amount of physiological saline and heparin solution before and after, and also needs to perform two-time plugging work of the injector, and the continuity of the operation process is poor, so that the end part of the CVC/PICC catheter is easy to pollute when the injector is pulled out halfway, and the related operation is more time-consuming and labor-consuming when the CVC/PICC catheter with the double cavities is subjected to flushing and sealing operation while the use is inconvenient and unreliable.

In this regard, the present inventors have found and designed the present application step by step based on clinical years of working experience through searching for new, so as to solve the related technical problems.
