Description

Technical Field

[0001] The utility model relates to the technical field of venous pressure measuring instruments, in particular to a foldable central venous pressure measuring instrument. Background Art

[0002] Central venous pressure is one of the main indicators for clinical observation of hemodynamics. The level of central venous pressure depends on factors such as new functional blood volume, venous vascular tension, intrathoracic pressure, venous blood return, and pulmonary circulation resistance. Clinicians will adjust the patient's fluid replacement volume based on the measured central venous pressure. A central venous pressure measuring ruler is required for central venous pressure measurement.

[0003] However, the existing central venous pressure measuring ruler is fixed on the infusion pole with elastic straps arranged above and below. When the zero point is not aligned with the patient's mid-axillary line, due to the elasticity of the elastic strap, medical staff may easily use excessive force when adjusting the central venous pressure measuring ruler, resulting in a large displacement of the central venous pressure measuring ruler. Therefore, in order to correct the above defects, we propose a foldable central venous pressure measuring instrument. Utility Model Content
