Skin fixator

Abstract

The invention provides a skin fixator. The skin fixator includes a flexible outer casing pipe, a flexible inner casing pipe, a fixing string and a skin suture needle; the inner casing pipe includes a main pipe, the head end of the main pipe is provided with a skin fixing head, and a through hole which is communicated with the main pipe is formed in the skin fixing head; the portion, close to skin, of the main pipe is provided with a fixing part and a thread outlet hole; the tail end of the main pipe is inserted in the head end of the outer casing pipe, and the outer surface of the main pipe is attached to the inner surface of the outer casing pipe; the fixing string is arranged in the main pipe and the outer casing pile in a penetrating mode, and the head end of the fixing string stretches out of the main pipe through the thread outlet hole; the skin suture needle is connected to the head end of the fixing string. The skin fixator is simple in structure, reasonable in design and convenient to install, and the operation process of catheter fixing is greatly simplified; sliding structures of the inner and outer casing pipes, the fixing string and the skin suture needle are adopted to conduct fixing, and the possibility that a catheter slips inwards or outwards is avoided; the fixing effect is reliable; the fixing string is fixed on the inner casing pipe in a twined mode and not directly tied on the catheter and has no squeezing action to the catheter, and the liquid flowing in the catheter is not influenced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a skin fixator. Background technique [0002] In clinical medicine, it is a common method to indwell a catheter in a blood vessel (artery or vein) so as to deliver various medicines, nutrients and other liquids to the body. Intravascular indwelling catheters need to be firmly fixed on the skin to ensure that the catheters do not fall off, which is a key step in indwelling catheters. [0003] At present, the commonly used methods in clinical practice are fixed by simple suture suture or fixed by external adhesive tape. Among them, the suture suture fixing method, because the suture is directly tied on the catheter, if the strength is too loose, the catheter will not be fixed firmly and will easily fall off; if the strength is too high, the catheter will be squeezed, hindering the flow of fluid in the lumen. So it is difficult to achieve just the right fixation. However,...
