Problems solved by technology

However, the B-ultrasound-guided puncture that can be used as a gold indicator for puncture guidance does not have the advantage of popularization in terms of the current domestic medical conditions due to its high price and inconvenient use. Therefore, a sufficiently low-cost visualization alternative is found. imminent

Abstract

The invention discloses an arterial pulse positioning development sheet, which comprises a display device and is characterized in that the display device is of a multi-layer structure which, from top to bottom, sequentially comprises an upper polarizing plate, a hard transparent material layer, an upper transparent conductive layer, an upper alignment film, liquid crystal layer, a lower alignment film, a transparent dot matrix conductive layer, a transparent piezoelectric film layer, lower transparent conductive layer, a lower polarizing plate and a pressure sensitive adhesive coupling layer; and a reflective layer is additionally arranged between the upper polarizing plate and the pressure sensitive adhesive coupling layer. The development sheet disclosed by the invention, on the basis of arterial pulsation and the property of being not easy to press, provides a cheap and convenient visualization solution for vascular puncture through the piezoelectric property of piezoelectric materials which are sensitive to dynamic mechanical vibration and in coordination with the intuition of liquid crystal display, so as to greatly reduce a failure rate caused by blind puncture.

Description

technical field [0001] The invention relates to the medical field, in particular to an arterial pulse localization developing sheet for arterial puncture. Background technique [0002] Clinical invasive vascular puncture (arteries, deep veins) is mostly carried out by touching specific arterial pulse points in specific areas on the body surface and traveling along the arterial or accompanying venous puncture. Since there is no objective indication of the puncture blood vessel on the body surface, the success rate is affected by various uncontrollable factors such as room temperature, patient body temperature, heart rate, blood pressure, operator experience, fingertip feeling, fingertip's own arterial pulsation interference, and even emotion. The time-consuming difference between arterial puncture and puncture is huge, and the literature discusses the success rate of arterial puncture with various methods abound. However, B-ultrasound-guided puncture, which can be used as a ...
