Description

Technical Field

[0001] The utility model relates to the technical field of central venous pressure measurement, in particular to a central venous pressure measurement device that can be stored. Background Art

[0002] Central venous pressure refers to the pressure near the superior and inferior vena cava and the right atrium. It can reflect changes in blood volume, venous return, right ventricular filling pressure or right heart function. Monitoring of central venous pressure has important clinical significance for understanding circulating blood volume and right heart function, and is a common and simple method for guiding fluid therapy. There are currently two methods for measuring central venous pressure: one is transducer measurement, and the other is manual ruler measurement.

[0003] For example, a central venous pressure measuring device with application number CN202120141452.7 and authorization announcement date 20211221 includes: a base; a lifting mechanism, which is arranged on the base; a measuring ruler body, which is arranged on the lifting mechanism, and a vertical scale is provided on the measuring ruler body; a laser emitter, which is horizontally arranged on the measuring ruler body; wherein the lifting mechanism can drive the measuring ruler body and the laser emitter to move up and down in the vertical direction. After adopting this device, when using it, first fix the base, then adjust the lifting mechanism so that the emission direction of the laser emitter is flush with the patient's atrium plane, and then vertically install the patient's infusion tube on the measuring ruler body, and the central venous pressure can be read from the measuring ruler body. Compared with the prior art, this device has a simple structure and is easy to operate, and can quickly and accurately measure the patient's central venous pressure.

[0004] The manual ruler measurement method requires the use of a ruler device, which requires medical staff to carry a ruler with them during measurement, which is inconvenient. In addition, medical staff need to hold the ruler by hand to avoid measurement errors, which makes the measurement operation more difficult. Therefore, it is urgent to design a central venous pressure measurement device that can be stored to solve the above problems. Utility Model Content
