Embodiment Construction

[0013] The following combined with the attached drawings and the specific embodiments to further explain the present invention:

[0014] The central vein pressure measurement ruler, the measurement ruler is a transparent structure of the mezzanine 1, the filling in the mezzanine 1 is used to indicate the level of the horizontal position.The direction is provided with a card slot 2 used for the liquid pipe tube, and the side of the card slot 2 has the scale 3 for measuring intravenous pressure;At the support rod 6 at the two ends of the base 5, the support rod 6 is the adjustable length of the adjustable length. The two sides of the measuring ruler's width direction can be rotated by the rotating shaft and the support rod 6.Keep vertical.The length of the measuring ruler is 20-35cm, and the card slot 2 at both ends of the measuring ruler sets a fixed card 7 for fixed infusion pipes.

[0015] The liquid filled in the mezzanine 1 is a non -color liquid.

[0016] The support rod 6 in ...

Abstract

The invention mainly discloses a central venous pressure measurement scale which is of a transparent structure with an interlayer filled with liquid for indicating the horizontal position. The volume of the liquid is no more than two thirds of that of the interlayer. A clamping groove for clamping an infusion tube is arranged on the measurement scale along the length direction of the measurement scale, and scales for measuring venous pressure are formed on the side of the clamping groove. The measurement scale is arranged on a bottom rack which comprises a base and supporting rods perpendicularly arranged at two ends of the base. Two sides of the measurement scale in the width direction are rotatably connected with the supporting rods through rotary shafts, and the measurement scale keeps perpendicular in a free state by means of the positions of the rotary shafts. By means of the horizontal principle, the central venous pressure measurement scale can measure patients' central venous pressure accurately, and is simple in operation, convenient and fast and capable of avoiding deviation of the measured value caused by out of plumb or deformation of the infusion tube, ensuring accuracy of central venous pressure (CVP) measurement results and ensuring true judgment of state of an illness and normal treatment of the illness of patients.

Description

Technical field [0001] The invention is the field of medical device, which mainly involves a central venous pressure measurement ruler. Background technique [0002] The measuring central vein pressure has two schemes: automatic monitoring and manual measurement of sensors. The former is connected to the sensor through the central venous duct to achieve continuous monitoring of the automatic schools of the monitor.Sex; the latter is very simple, the operation is simple, the operation is simple, the price is low, and it is widely used in various clinical departments.For the second measurement method, clinical medical staff often use traditional visual inspection or straight ruler for two levels of levels, but this method is prone to deviations in the use, and the ruler is not vertical to make the measurement value large;, The measurement value is large; if the infusion device is not straightened and there is a curved, the measurement value is small.The measuring value has a deviat...
