Problems solved by technology

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 The zero position, and keep the extension tube vertical; another person holds the scale to measure and read, and the operation is time-consuming and laborious; 3. The extension tube and the scale need to be held in the process, which is easy to hold unstable and cause inaccurate readings
The first is to improve the zero point positioning device, such as the application number CN201420105100.6, CN201520262061.5, this kind of patent does not improve the reading link; the second one improves the reading link during measurement, such as the application number is CN201320711564.7, CN201420546298 .1, CN201410068279.7, CN201520262061.5, CN201520277534.9, etc., this patent does not improve the zero point positioning link; the third type has improved the zero point positioning device and the measurement and reading link, such as CN201420105100.6, but requires pressure conversion Device, computer, three three-channel rotary valves, etc., the cost of use is relatively high

Embodiment Construction

[0028] The content described in the embodiments of this specification is only an enumeration of the implementation forms of the inventive concept. The protection scope of the present invention should not be regarded as limited to the specific forms stated in the embodiments. The protection scope of the present invention also extends to the field Equivalent technical means that the skilled person can think of based on the concept of the present invention.

[0029] Such as figure 1 and figure 2 As shown, the tool for measuring central venous pressure for quickly locating the zero point of the present invention includes four parts: a clamping component, a measuring component, an equally divided telescopic strip 3 and a clamping plate 2 . Among them, the clamping component is used to engage the chest of the human body and locate the zero point position; the measuring component is used to measure the central venous pressure; the clamping plate 2 is used to fix the back of the hum...

Abstract

The invention relates to a central venous pressure measuring tool with a quick zero positioning function, comprising a clamping component, an equally-divided expansion bar, a clamping plate and a measuring component. The clamping component and the measuring component are connected to the equally-divided expansion bar. The equally-divided expansion bar is movably connected to the edge of the clamping plate. The invention ingeniously invents a tool which is used for being clamped onto the body of a patient, has a quick zero positioning function and can measure the central venous pressure. The zero of the tool can be located quickly and accurately. The central venous pressure of patients can be measured accurately and quickly by using the tool. Moreover, the tool can be operated by one personconveniently and quickly, the measuring time is shortened, and the amount of nursing work can be greatly reduced. In addition, the tool is foldable and easy to carry and place. The tool costs low, and is easy to be popularized and applied.

Description

technical field [0001] 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 [0002] 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...
