Embodiment Construction

[0009] Such as figure 2 As shown, on the outer surface of the spring skeleton 4, the indexing line 3 is corroded electromechanically with S-101 color code. Such as figure 1 As shown, extruding the spring skeleton 4 inside the outer plastic protective layer 2 of the anesthesia catheter 1 forms the present invention. The present invention forms the index line 3 by electrocorrosion, and such index line 3 is formed by the decomposition of the spring skeleton 4 under certain conditions, so it does not have the problems of shedding, dissolution, and volatilization. In addition, the spring frame 4 is extruded in the outer plastic protective layer 2, and its index line 3 is designed between the spring frame 4 and the outer plastic protective layer 2, and is closely protected by the outer plastic protective layer 2, so that the anesthesia catheter 1 Its indexing line 3 behind the human body does not directly contact with the human body and the anesthetic, so it has absolutely no sid...

Abstract

The invention relates to a reticule for a disposable anesthesia catheter. The reticule comprises a spring framework and an outer plastic protective layer. The spring framework is extruded in the outer plastic protective layer to form a catheter wall. The outer plastic protective layer is made of a transparent material. The reticule is characterized in that the reticule is attached to the outer surface of the spring framework. The reticule is formed by a method of electrically corroding the surface of the spring framework. Compared with conventional reticule for the anesthesia catheter, the technical contribution of the invention is that the reticule is not arranged on the outer surface of the anesthesia catheter but on the surface of the spring framework and between a spring and a plastic interlayer, so that, the reticule of the anesthesia catheter inserted into the human body is not directly contacted with the human body and anesthetic. The reticule provided by the invention has the remarkable advantages of 100% safety, absolute reliability, no any side effects and the like.

Description

technical field [0001] The invention relates to a graduation line on a disposable anesthesia catheter, in particular to an attachment position of the graduation line on a disposable anesthesia catheter and a forming method thereof, belonging to the technical field of medical device manufacturing. Background technique [0002] Disposable anesthesia catheters are widely used in medical anesthesia clinics. In order to accurately distinguish the length of the catheter entering the human body, eye-catching circumferential graduation lines are usually marked on the outer wall surface of the anesthesia catheter. The traditional method of marking the graduation line is formed by attaching a chemical colorant to the outer surface of the catheter. The chemical colorant is generally blended with chemical solvents such as carbon tetrachloride, phenol, and T-117 special black paste. As we all know, all the chemical solvents used for coloring are harmful to the human body to varying degre...
