Referring to fig. 1, a central venous pressure measurement device in an embodiment of the present invention includes a column 10, a sleeve 20, and a laser positioning device 30.

The bottom of the upright post 10 is provided with the base 11, so that the device can be independently placed and used without being additionally fixed on other equipment, and the use is more flexible and convenient. The column 10 is cylindrical or prismatic. The top of the column 10 is provided with a hanger to facilitate the hanging of saline for measuring central venous pressure.

The sleeve 20 is sleeved on the upright post 10, the sleeve 20 can move along the upright post 10, and the sleeve 20 can be fixed on the upright post 10 through a positioning mechanism. Optionally, the positioning mechanism includes at least one bolt 21, the sleeve 20 is provided with at least one screw hole, and the bolt 21 is abutted to the pillar 10 after penetrating through the screw hole. In the embodiment, the number of the bolts 21 is two, the number of the screw holes on the sleeve 20 is two, the two screw holes are arranged at intervals along the length direction of the column 10, and the laser positioning device 30 is located between the two screw holes, so that not only is the sleeve 20 ensured to be stably fixed on the column 10, but also the axial direction of the sleeve 20 is ensured to be substantially parallel to the length direction of the column 10, and the condition that the zero point positioning reading is inaccurate due to the offset of the sleeve 20 is avoided.

The sleeve 20 is provided with a groove 22 for mounting the central vein piezometric tube, the groove 22 is arranged along the length direction of the sleeve 20, and the sleeve 20 is also marked with scales along the length direction. The central venous pressure tube is held in the recess 22 and moves as the sleeve 20 moves.

The laser positioning device 30 is fixed to the sleeve 20. The laser positioning device 30 can emit laser light to align the position of the right atrium of the patient, thereby greatly reducing measurement errors and simplifying operation steps because the light always travels along a straight line. Preferably, the laser positioning device is fixed at zero point of the scale of the sleeve 20. Because the laser positioning device is fixed at the zero point of the scale of the sleeve 20, when the laser emitted by the laser positioning device is aligned with the right atrium of the patient, the reading of the central vein piezometer tube is directly read by contrasting the scale, so that the central vein pressure data of the patient can be obtained, and the accurate reading is facilitated.
