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.

Detailed Description
In order to illustrate embodiments of the present invention or technical solutions in the prior art more clearly, the following description will be made in conjunction with the accompanying drawings in embodiments of the present invention to describe the technical solutions in the embodiments of the present invention clearly and completely, and it is obvious that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
Please refer to fig. 1 and fig. 2 in combination, wherein fig. 1 is a schematic structural view of the atraumatic needle extension tube of the infusion port of the present invention; fig. 2 is a schematic structural view of the anchor shown in fig. 1. The extended long tube of the non-invasive needle of the transfusion port is connected to the non-invasive needle 10. The extended long tube 30 of the non-invasive needle of the infusion port comprises a tube body 31 detachably connected with the non-invasive needle 10, a scale mark 33 marked on the tube body 31, a catheter clamp 35 clamped on the tube body 31 and a fixer 37 connected on the tube body 31. The scale mark 33 is used for marking the length of the tube body 31, and when the medical staff clamps the catheter clamp 35 on the tube body 31, the accuracy of the clamping position of the catheter clamp 35 after the transfusion is finished can be effectively ensured by the scale mark 33 engraved on the tube body 31, so that the blockage and the port drawing caused by the thrombus formation in the tube cavity of the tube body 31 can be reduced.
