Auxiliary film for vascular catheterization operation

Abstract

The invention provides an auxiliary film for a vascular catheterization operation, and relates to the technical field of medical treatment. The auxiliary film for the vascular catheterization operation comprises a sterile sticking piece capable of being penetrated by ultrasonic waves, a first blocking piece and a second blocking piece, wherein the first blocking piece and the second blocking piece are used for preventing the ultrasonic waves from penetrating through the sticking piece, are arranged on the sticking piece and can be directly stuck on an ultrasonic probe, so that the preoperative preparation time is short; and the first blocking piece and the second blocking piece are convenient for guiding a puncture needle to select a puncture position and helping the puncture needle to be stably and safely inserted into a blood vessel, so that accurate and safe intubation is realized, and the generation of mechanical complications is reduced.

Description

technical field

[0001] The invention relates to the field of medical technology, in particular to an auxiliary patch used in vascular catheterization operations. Background technique

[0002] Real-time ultrasound-guided vascular (arterial or venous) cannulation has become a standard surgical approach with higher success rates and fewer mechanical complications than anatomically landmarked techniques. At present, the commonly used methods for ultrasound-guided vascular cannulation include short-axis out-of-plane and long-axis in-plane.

[0003] However, both the short-axis out-of-plane technique and the long-axis in-plane technique have major disadvantages. The short-axis out-of-plane technique and the long-axis in-plane technique are used independently, and the observation range is narrow, and the puncture needle is easy to puncture other tissues by mistake, resulting in Numerous mechanical complications occurred.

[0004] We propose an improved combination of short and lo...
