Abstract

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

Central Venous Pressure Measuring Tape

technical field

    The invention belongs to the field of medical equipment, and mainly relates to a central venous pressure measuring ruler.

Background technique

There are two methods 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 staff 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 value is too large; if the infusion set is not straightened and there is a bend, the measured value is too small. Deviations in the measurement values will affect the accuracy of the CVP measurement results, thereby affecting the judgment of the patient's condition and normal treatment.

Contents of the invention

The purpose of the present invention is to provide a central venous pressure measuring ruler for the deficiencies in the prior art. The measuring ruler can accurately measure the central venous pressure of a patient based on the principle of a horizontal plane, and the operation is simple, convenient and fast, ensuring the patient's condition. Correct judgment and normal treatment.

The technical solution adopted by the present invention to achieve the above object is: central venous pressure measuring ruler, the measuring ruler is a transparent structure provided with an interlayer, the interlayer is filled with liquid for indicating the horizontal position, and the volume of the liquid does not exceed 2% of the volume of the interlayer /3, the measuring ruler is provided with a slot for clamping the infusion tube along its length direction, and a scale for measuring venous pressure is provided on the side of the slot; the measuring ruler is arranged on the bottom frame, which includes a base and The supporting rods are vertically arranged at both ends of the base, and the two sides of the measuring ruler along the width direction are rotatably connected to the supporting rods through rotating shafts, and the setting position of the rotating shaft keeps the measuring ruler vertical in a free state.

The liquid filled in the interlayer is a colored liquid.

The length of the measuring ruler is 20-35cm.

Fixing cards for fixing the infusion tube are respectively provided at the card slots at both ends of the measuring ruler.

The support rod is a telescopic rod with adjustable length.

Beneficial effects of the present invention

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.

Detailed ways

The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

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. Keep it vertical. The length of the measuring ruler is 20-35cm, and the fixing clips 7 for fixing the infusion tube are respectively provided at the slots 2 at both ends of the measuring ruler.

The liquid filled in the interlayer 1 is a colored liquid.

The support rod 6 in the present invention is a telescopic rod with adjustable length. Generally speaking, the normal length it presents is the situation where the measuring ruler is directly placed on the sick bed. For the situation that is not suitable for being placed on the sick bed, the support rod 6 can be adjusted. Make the zero point of the measuring ruler correspond to the position of the midaxillary line when the human body lies supine with the pillow removed as much as possible.

The method of use of the present invention is as follows: place the device on a sickbed, set the infusion tube for measuring venous pressure in the slot 2 of the measuring ruler, and fix it by the fixing card 7, and the measuring ruler is perpendicular to the horizontal plane according to its own gravity , so that the liquid level of the liquid in the interlayer 1 is parallel to the horizontal plane, and the infusion tube is accurately perpendicular to the horizontal plane. When the liquid level in the infusion tube is stable, read the indicated value of the scale 3 on the measuring ruler, record the data, and complete the central venous pressure measurement.

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.
