Abstract
The present invention essentially discloses a kind of centre venous pressure measuring rule, described dip stick is for establishing transparent configuration with dissection, the liquid being used to indicate horizontal level is filled with in interlayer, the volume of liquid is no more than 2/3 of interlayer volume, dip stick is provided with the draw-in groove establishing tube for transfusion for card along its length, and the side of draw-in groove is provided with the scale for measure venous pressure; Described dip stick is arranged on underframe, underframe comprises base and is vertically set on the support bar at base two ends, dip stick both sides are in the width direction rotatably connected respectively by rotating shaft and support bar, and the setting position of rotating shaft makes dip stick keep vertical in a free state.Centre venous pressure measuring rule provided by the invention is according to water surface rule, can the central venous pressure of Measurement accuracy patient, and it is simple to operate, convenient and swift, avoid tube for transfusion out of plumb or deformation occurs, cause measured value to occur deviation, affect the accuracy of CVP measurement result, ensure that correct judgement and the normal therapeutic of conditions of patients.
Description
Technical field
The invention belongs to medical instruments field, relate generally to a kind of centre venous pressure measuring rule.
Background technology
Mensuration central vein is pressed with sensor and automatically monitors and measure two schemes by hand, the former is connected with sensor by central venous catheter, realize monitor automatic zero adjustment and realize monitoring continuously, but not all section office there are monitor and sensor device, there is the limitation used; The latter because of pressure tester simple, easy and simple to handle, cheap, apply widely in each clinical department.For the second assay method, clinical staff often uses tradition range estimation or ruler to carry out WAWQ and puts down zero, but the method in use very easily occurs deviation, scale out of plumb, makes measured value bigger than normal; Transfusion device is elongated, and measured value is bigger than normal; If transfusion device is not straightened, exist bending, then measured value is less than normal.There is deviation in measured value, affects the accurate of CVP measurement result, thus affect judgement and the normal therapeutic of conditions of patients.
Summary of the invention
The object of the invention is, for deficiency of the prior art, to provide a kind of centre venous pressure measuring rule, this dip stick is according to water surface rule, can the central venous pressure of Measurement accuracy patient, and simple to operate, convenient and swift, ensure that correct judgement and the normal therapeutic of conditions of patients.
The technical scheme that the present invention realizes above-mentioned purpose employing is: centre venous pressure measuring rule, described dip stick is for establishing transparent configuration with dissection, the liquid being used to indicate horizontal level is filled with in interlayer, the volume of liquid is no more than 2/3 of interlayer volume, dip stick is provided with the draw-in groove establishing tube for transfusion for card along its length, and the side of draw-in groove is provided with the scale for measure venous pressure; Described dip stick is arranged on underframe, underframe comprises base and is vertically set on the support bar at base two ends, dip stick both sides are in the width direction rotatably connected respectively by rotating shaft and support bar, and the setting position of rotating shaft makes dip stick keep vertical in a free state.
The liquid of filling in described interlayer is colored liquid.
The length of described dip stick is 20-35cm.
The fixing card for fixing tube for transfusion is respectively equipped with at the draw-in groove place at the two ends of described dip stick.
Described support bar is the expansion link of adjustable length.
Beneficial effect of the present invention
Centre venous pressure measuring rule provided by the invention is according to water surface rule, can the central venous pressure of Measurement accuracy patient, and it is simple to operate, convenient and swift, avoid tube for transfusion out of plumb or deformation occurs, cause measured value to occur deviation, affect the accuracy of CVP measurement result, ensure that correct judgement and the normal therapeutic of conditions of patients.

Fig. 1 is structural representation of the present invention;
Reference numeral: 1, interlayer, 2, draw-in groove, 3, scale, 4, underframe, 5, base, 6, support bar, 7, fixing card.
Detailed description of the invention
below in conjunction with the drawings and specific embodiments, the present invention will be further described:
Centre venous pressure measuring rule, described dip stick is the transparent configuration being provided with interlayer 1, the liquid being used to indicate horizontal level is filled with in interlayer 1, the volume of liquid is no more than 2/3 of interlayer 1 volume, dip stick is provided with the draw-in groove 2 establishing tube for transfusion for card along its length, and the side of draw-in groove 2 is provided with the scale 3 for measure venous pressure; Described dip stick is arranged on underframe 4, underframe 4 comprises base 5 and is vertically set on the support bar 6 at base 5 two ends, support bar 6 is the expansion link of adjustable length, dip stick both sides are in the width direction rotatably connected respectively by rotating shaft and support bar 6, and the setting position of rotating shaft makes dip stick keep vertical in a free state.The length of described dip stick is 20-35cm, is respectively equipped with the fixing card 7 for fixing tube for transfusion at draw-in groove 2 place at the two ends of described dip stick.
The liquid of filling in described interlayer 1 is colored liquid.
Support bar 6 in the present invention is the expansion link of adjustable length, generally, its normal length presented is situation about being placed directly in by dip stick on sick bed, for situation about should not put on one's sick bed, the length of support bar 6 can be regulated, make to go to human body the zero point of dip stick midaxillary line position when resting the head on flat crouching corresponding as far as possible.
Using method of the present invention is: be placed in by this device on sick bed, the tube for transfusion being used for measure venous pressure is fastened in the draw-in groove 2 of dip stick, and fixed by fixing card 7, dip stick perpendicular to horizontal plane, thus makes liquid level and the plane-parallel of the liquid in interlayer 1 according to self gravitation, and makes tube for transfusion accurate vertical in horizontal plane, treat the liquid level stabilizing in tube for transfusion, read scale 3 indicated value on dip stick, record data, namely complete the measurement of central venous pressure.
Centre venous pressure measuring rule provided by the invention is according to water surface rule, can the central venous pressure of Measurement accuracy patient, and it is simple to operate, convenient and swift, avoid tube for transfusion out of plumb or deformation occurs, cause measured value to occur deviation, affect the accuracy of CVP measurement result, ensure that correct judgement and the normal therapeutic of conditions of patients.
