Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:
[0014] Central venous pressure measuring ruler, the measuring ruler is a transparent structure provided with an interlayer 1, the interlayer 1 is filled with liquid for indicating the horizontal position, the volume of the liquid does not exceed 2 / 3 of the volume of the interlayer 1, and the measuring ruler along its length The direction is provided with the draw-in groove 2 that is used to clamp the infusion tube, and the side of the draw-in groove 2 is provided with the scale 3 that is used for measuring venous pressure; The support rods 6 at both ends of the base 5 are telescopic rods with adjustable length. The two sides of the measuring ruler along the width direction are rotatably connected to the supporting rods 6 through the rotating shaft respectively. The setting position of the rotating shaft makes the measuring ruler in a free state. Ke...

The invention mainly discloses a measuring ruler for central venous pressure. The measuring ruler is a transparent structure provided with an interlayer. The interlayer is filled with liquid for indicating the horizontal position. The volume of the liquid does not exceed 2 / 3 of the volume of the interlayer. The ruler is provided with a draw-in slot for clamping the infusion tube along its length direction, and a scale for measuring venous pressure is provided on the side of the draw-in slot; The supporting rods at both ends and the two sides of the measuring ruler along the width direction are respectively rotatably connected to the supporting rods through a rotating shaft, and the setting position of the rotating shaft keeps the measuring ruler vertical in a free state. The central venous pressure measurement ruler provided by the present invention can accurately measure the central venous pressure of a patient based on the principle of a horizontal plane, and is easy to operate, convenient and fast, and avoids the problem that the infusion tube is not vertical or deformed, causing deviation in the measured value and affecting the CVP measurement result. The accuracy ensures the correct judgment and normal treatment of the patient's condition.
Description
technical field [0001] The invention belongs to the field of medical equipment, and mainly relates to a central venous pressure measuring ruler. Background technique [0002] There are two solutions for measuring central venous pressure: automatic sensor monitoring and manual measurement. The former is connected to the sensor through a central venous catheter to realize automatic zeroing of the monitor and continuous monitoring. However, not all departments have monitors and sensor equipment, and there are limitations in use. The latter is widely used in various clinical departments because of its simple manometry device, easy operation and low price. For the second measurement method, clinical medical personnel often use traditional visual inspection or a ruler to carry out two-point horizontal alignment, but this method is prone to deviation during use, and the scale is not vertical, which makes the measured value too large; the infusion set is elongated , the measured va...
