Description

A tool for measuring central venous pressure by quickly locating the zero point

technical field

The invention belongs to medical nursing auxiliary devices, and relates to a central venous pressure measuring tool, which can be operated independently, quickly locate the zero point, and can conveniently and accurately measure the central venous pressure.

Background technique

Measuring the central venous pressure is one of the common clinical operations. The central venous pressure can show the actual capacity of the body to bear the volume load. guide clinical treatment. The traditional measurement method is: when the patient is in a quiet state, the main lumen of the central venous catheter is connected to the tee and the extension tube. The entire extension tube is filled with normal saline and there is no air. At the zero position, close the extension tube upwards, and take a reading at the end of expiration after the liquid level in the extension tube stabilizes. Among them, the zero point is the intersection of the horizontal line at the upper 2/3 of the patient's back and the fourth intercostal space. There are three problems in this measurement method: 1. It is difficult to determine the zero point position, and the zero point positioning varies greatly among different operators, resulting in inaccurate measurement; 2. This operation usually requires two nurses to complete, that is, one person determines Zero position, and keep the extension tube vertical; Another person holds the scale to measure and read, which is time-consuming and laborious to operate; 3. The extension tube and scale need to be held in the process, which is easy to hold unstable and cause inaccurate readings. At present, there are improved central venous pressure measurement patents clinically, which are mainly divided into three types.
