Description

Epitaxial long tube of not damaged needle in infusion port

Technical Field

The utility model relates to the technical field of medical equipment, especially, relate to an epitaxial long tube of infusion port not damaged needle.

Background

The transfusion port is a vein transfusion device which is completely implanted under the skin and can be left in the body for a long time, and is also an important tool for the transfusion of chemotherapy drugs of tumor patients. At present, the infusion port is widely applied in clinic, medicine infusion is carried out by adopting the infusion port, a channel with a blood vessel can be established only by matching with a non-destructive needle, the non-destructive needle is provided with an extension long tube, the non-destructive needle punctures a base of the infusion port, blood return can be pumped back for use, and the extension long tube part of the non-destructive needle generally carries a catheter clamp so as to prevent the catheter blood return from causing catheter blockage before and after infusion.

Research shows that when the front 1/4 section of the outer extension tube is clamped by the catheter, the influence on the outer extension tube caused by the increase of the pressure in the blood vessel is small due to the small stress area, the blood backflow of the lumen of the extension tube is reduced, and the incidence rate of tube blockage is also reduced. If the transfusion clip is clamped at the far end of the external extension tube, the patient moves slightly or exerts force, the extension tube is easy to generate negative pressure, blood returns from the lumen of the extension tube, the non-damage needle presents a right angle, the blood returns are easy to stay at the front end of the non-damage needle, and once the blood returning time is too long, thrombus is easy to form in the lumen to cause blockage and port drawing. The 1/4 assessment of the outer extension tube is prone to bias due to individual caregiver variability. And after the atraumatic needle is connected with the base of the transfusion port, the external extension tube needs to be properly fixed, and a medical adhesive tape fixing method is generally adopted at present, but the fixing method is easy to loosen, nursing staff need to frequently replace the needle, and the workload is increased. The extension tube is not fixed well, so that traction pain or traumatic needle falling off is easy to cause extravasation and the like, and in addition, most patients are allergic to the medical adhesive tape, and complications such as skin injury related to the medical adhesive tape and the like are caused. At present along with the use of novel infusion port technique and the consciousness reinforcing of safe infusion, how to reduce the bad experience of infusion port technique, improve patient's infusion and experience, guarantee that becoming more meticulous of nursing staff's work has become the key of current venous transfusion research.
