Catheter fixing device

Abstract

The invention provides a catheter fixing device. The catheter fixing device comprises a supporting belt and a self-connecting piece, wherein the supporting belt is provided with a first surface and a second surface deviating from the first surface; the self-connecting piece is partially or completely arranged on the second surface of the supporting belt; and one end of the supporting belt is folded back towards the first surface in the bending direction through a crack formed in the supporting belt to form a catheter penetrating opening, and a limb end fixing opening adjacent to the catheter penetrating opening is formed in the mode that the end of the supporting belt is converged with the other end of the supporting belt along a path, wherein at least one part of the path comprises a curve advancing direction which changes the extending direction of the supporting belt so that one end of the supporting belt can be converged with the other end of the supporting belt. According to the catheter fixing device, an element used for resisting excessive binding force is arranged on the fixing device so that a medical hose can be fixed without influence.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a catheter fixing device. Background technique [0002] Vascular surgery mainly focuses on the prevention, diagnosis and treatment of peripheral vascular diseases other than cerebrovascular and cardiovascular diseases. After vascular surgery, patients often have urinary catheters placed outside the body. In a few surgeries designed for heart, artery and other parts, there may be cases where external blood vessels such as veins and arteries are bypassed so that important pipelines exist outside the body. When the patient is cured after surgery, the tubing placed outside the body often needs to remain still and in the same position to ensure orderly blood flow in the body or no damage to the bladder. [0003] The Chinese patent with the patent number CN208838837U provides a medical pipeline fixing sticker, which includes a prefabricated body, the prefabricated body includes a no...

Problems solved by technology

The device fixes the pipeline by clamping the pipeline, and fixes the position of the pipeline by pasting it on any part of the human body surface, but the connection method of pasting will cause great damage to the human skin. The fixation of the pipeline is more of a wrap-around binding type, and the tube is fixed by the Velcro on the reverse side. However, when the tube is bound or clamped, the degree of adjustment depends entirely on the strength of the hand, which is likely to affect the urine. Tubes, peripheral venous tubes and other hoses are tightened so that the diameter of some areas of the hose becomes smaller, resulting in poor circulation. A Chinese patent with a publication number of CN108348731A discloses a fixing system for fixing multi-chamber medical products by sticking on An adhesive base of the body, a flap of the free distal portion securing the proximal portion to move between an open position and a closed position, and a hinge having a lateral width less than the lateral width of the patch and smaller than the lateral width of the flaps implement the card The device is not bound and fixed to the body, but the method of sticking is still used, and the way the wings are engaged with the fixed catheter may move the catheter along the patch, making the catheter unstable
