A kind of run-proof tubular venous catheter

Abstract

The invention provides an anti-displacement tube type ductus venosus which sequentially comprises a catheter, a connecting base and an extension pipe, and the catheter, the connecting base and the extension pipe are connected and communicated with one another. The portion, in the position of the opening of the connection base, of the catheter is of a needle base structure, and a puncture needle is inserted into the catheter through the needle base structure. The extension pipe is sequentially communicated with the connecting base and the catheter through the side wall of the connecting base. Catheter fixing wings and a float are sequentially arranged on the connection position of the connection base and the catheter, the faces, attached to the human skin, of the catheter fixing wings and the face, attached to the human skin, of the float are respectively provided with a sticking and fixing structure, and each sticking and fixing structure sequentially comprises a sticking layer and a protection layer from inside to outside. The anti-displacement tube type ductus venosus is convenient to use, easy to operate, good in fixing effect, and capable of effectively preventing a patient from great pains which are produced when the exposed portion of an anti-displacement tube type ductus venosus body is sewn on and fixed to the skin through the puncture needle and threads in a percutaneous mode, the anti-displacement tube type ductus venosus can be effectively prevented from being blocked, when negative pressure exists in the anti-displacement tube type ductus venosus, an opening can be effectively formed, medical staff can conveniently draw return blood so as to confirm whether the ductus venosus is placed in the vein or not and can conveniently draw back hydrops so as to confirm whether the hydrops exists in the body cavity or not, life health of the patient can be effectively ensured, and dangers are prevented from occurring.

Description

Technical field [0001] The invention relates to a medical device, in particular to an anti-run tube type intravenous catheter. Background technique [0002] Intravenous catheter placement is a common clinical detection and treatment method. Through the fixed venous catheter entrance, blood transfusion, fluid replacement, various postoperative treatment medications, parenteral nutrition, etc. can be performed. At the same time, the intravenous catheter can also be used for puncture of body cavity fluid. Drainage has many advantages such as less trauma, high drainage efficiency, and fast healing. Compared with traditional puncture methods, it has high safety, avoids the pain caused by repeated punctures to patients, improves patient compliance, and improves the efficiency of medical staff. And gradually promoted and popularized in the country. After the intravenous catheter is inserted into the body, there will be a section of the tube exposed outside the body, and if the exposed ...

AI Technical Summary

Problems solved by technology

After the venous catheter is inserted into the body, a section of the tube body will be exposed outside the body. If the exposed tube body is not fixed, it is easy to cause the tube body to fall off, run away and need to be punctured again, which will increase the pain of the patient and the work of the medical staff. It may also cause the venous catheter to move out of the blood vessel and the drug solution to enter the interstitial space and cause the failure of the drainage of body cavity fluid, which puts the patient in danger at any time

Therefore, the fixation of the exposed tube is very important, and the existing fixation of the tube, in addition to the percutaneous suture of the fixed wing structure of the catheter with needles and threads, also requires knotting and fixing the exposed tube, and if the knot is too tight, it will Large infusion resistance, loose knots will result in poor fixation effect, prone to catheter displacement, prolapse and other problems

Chinese patent CN102500039A discloses a double-cavity central venous catheter. Although the exposed tube body is fixed through the buoy structure, it avoids the high infusion resistance caused by too tight knots or the poor fixation effect caused by too loose knots, which is prone to catheter displacement. problems such as prolapse, but it does not solve the technical problem that the fixation method that is sutured on the skin with needles and threads causes great pain to the patient
