Description
Technical field:
The utility model is related to mankind life article more particularly to medical instrument, especially a kind of measurement of central venous pressure
Device.
Background technology
Measuring center vein pressure is basic and common monitoring means in haemodynamics detection, is held to assess patient's blood
Amount, cardiac preload and right heart function, central venous pressure are also the important reference indicator of clinical fluid infusion velocity and amount infused.Tool
Pressure measurement zero should the 4th intercostal of midaxillary line in the same horizontal line and when horizontal position, when semireclining position, lock with atrium dextrum when bulk measurement
Bone center line third intercostal, the second intercostal of right side takes horizontal position, avoids pressure measurement errors as possible to reduce error when seat.
In the prior art, by connecting multifunctional monitor with pressure sensor with energy converter, sustainable monitoring center is quiet
Pulse pressure dynamic change, but relevant device is usually only equipped in intensive care unit.So in clinical application, more usually hand
Measuring central venous pressure, i.e. infusion apparatus connect physiological saline, after drain, set and are connected at pipe, then by infusion apparatus in physiological saline connector
Place is extracted, and in the 4th rib of midaxillary line, fixes zero, and liquid automatic descending in woven hose is then allowed then to be used to not being reduced to only
Ruler measures the height of liquid, so that it may measure central venous pressure numerical value.Although hand measuring central venous pressure needs equipment to compare
Simply, but the gimmick to operating personnel and experience have very high requirement, on the one hand operate it is time-consuming and laborious, on the other hand often due to
Accurate fixed zero or it can not can not ensure liquid level and influence to measure precision.
Utility model content
The purpose of this utility model is that in view of the above-mentioned drawbacks in the prior art, providing a kind of simple in structure, operation side
Just, and the high center venous pressure measuring device of precision is measured.
Its main operational principle is by the way that weight body is arranged in measuring device lower end, ensures measuring device using gravity
Graduated scale remain perpendicular to horizontal plane direction, by buckle so that woven hose is quick and precisely fixed on graduated scale to make liquid level
Keep horizontal and graduated scale fixed zero accurate positioning.
To achieve the above object, the utility model uses following technical scheme：Center venous pressure measuring device, including one
Graduated scale, wherein it is provided with the buckle of more than two numbers on the graduated scale, includes card slot in the buckle, it is described
The width of card slot and the outer diameter of the woven hose of measuring center vein pressure match, and the woven hose is fixed on by the buckle
On graduated scale, the lower end of graduated scale is provided with weight body, and the scale on the graduated scale is using millimeter as least unit.
Further, there are two the heterochiral card slots of opening direction for the buckle tool, and the buckle is by transparent material system
At.
Further, 0 scale position, the weight body are magnet on the scale for the weight body setting.
Further, the graduated scale top is provided with suppending hole.
Further, the scale range on the graduated scale is 30 centimetres.
The utility model compares with prior art, and effect is positive and apparent.The utility model manufacturing cost is low,
It is easy to operate, it is easy to use.Operation skill and experience to operator do not require, and with compared with high measurement precision, side
Just clinical expansion.
Description of the drawings：
Fig. 1 is the structure chart of the utility model.
Specific implementation mode：
Embodiment:
As shown in Figure 1, a kind of center venous pressure measuring device, including a graduated scale 1, wherein it is set on the graduated scale 1
It is equipped with the buckle 2 of more than two numbers, includes card slot 6 in the buckle 2, the width and measuring center of the card slot 6 are quiet
The outer diameter of the woven hose 5 of pulse pressure matches, and the woven hose 5 is fixed on by the buckle 2 on graduated scale 1, graduated scale 1
Lower end is provided with weight body 3, and the scale on the graduated scale 1 is using millimeter as least unit.Outside due to card slot size and woven hose
Diameter matches, and being moved to graduated scale appropriate location convenient for woven hose is fixed, to make zero graduation and the atrium dextrum of graduated scale
Scale where reading liquid level is also allowed in the same horizontal line, simultaneously because graduated scale lower end is provided with weight body, it is practical to measure
When be affected by gravity entire graduated scale can be vertical with horizontal plane holding as vertical, so as to accurately measure in woven hose
The vertical height of liquid.
It further, can be to infusion as shown in Figure 1, the buckle 2 has there are two the heterochiral card slot 6 of opening direction
Pipe plays the role of twin fixed guide-vane, preferably prevents woven hose from shifting in the measurements, and the buckle 2 is made of clear material, this
Even if sample liquid level, which is snapped to block, nor affects on reading.
Further, as shown in Figure 1,0 scale position, the weight body is arranged on graduated scale 1 in the weight body 3
3 be magnet.Weight body, which is located at 0 scale, can be used as an apparent mark to facilitate fixed zero, while use magnet as counterweight
Body, which also facilitates to be adsorbed on center venous pressure measuring device on steel utensil common in ward, to be fixed
Further, as shown in Figure 1,1 top of the graduated scale is provided with suppending hole 4, by the way that graduated scale is suspended on conjunction
Right position, which is set, preferably to keep graduated scale vertical with horizontal plane holding using gravity, reduce woven hose deformation itself to entire center
The influence of vein pressure measuring device.
Further, as shown in Figure 1, the scale range on the graduated scale 1 is .30 centimetres, due to central vein positive pressure
Constant value is 5-10 centimetres, and when central venous pressure is less than 5 centimetres, expression hypovolemia prompts cardiac insufficiencies higher than 15 centimetres,
Vein blood vessel excess shrinkage or pulmonary vascular resistance increase.If being higher than 20 centimetres, indicate that there are congestive heart failures, thus 30 centimetres of amounts
Journey is sufficient for clinical demand.
