Abstract
The technical scheme of the utility model provides a central venous pressure zeroing device which is characterized by comprising a device body, wherein a trough for accommodating an infusion tube is formed on the front side of the device body, an indication ruler is formed on each of two sides of the device body on the trough, an extension bar is arranged on each of left and right sides of the device body, and when the central venous pressure zeroing device is used, the extension bar is vertical to the indication ruler on the same side by 90 degrees and the position of zero in each indication ruler and the center of circle of the end of each extension bar are on the same straight line. The utility model provides an auxiliary tool for zeroing for a nurse measuring the central venous pressure, the time and the labor are saved, the error resulting from visual inspection of zero is eliminated, and the safety of medical care and nursing of a patient is guaranteed.
Description
Technical field
When relating to measuring center venous pressure (being designated hereinafter simply as CVP) in a kind of nursery work, this utility model accurately determines the device of dead-center position.
Background technology
At present during clinical measurement CVP, mainly contain two kinds of methods, a kind of is by pressure transducer or transducer, is applicable to extremely critically, need continue to monitor the patient of circulatory function, generally only carries out in ICU.
Second method is hand dipping, is also that present clinical practice is more, carries out the wider method of scope, no matter ICU or public ward are all generally used.Its method is first to determine zero point, use the transfusion device reason saline of delivering a child, after aerofluxus with put the pipe place and be connected, flow into by the three way cock the empty liquid-transport pipe-line that another communicates with atmosphere, after liquid level rises to suitable height, allow liquid level automatic descending in pipeline till can not descend, then measure the height of fluid column with a yardstick, be the CVP value that records.The hand dipping method has inexpensive, required with thing convenient sources (of one bag of normal saline, blood exchange transfusion set's one pair, transfusion device one pair, drip stand), the advantage such as applied widely, is the main method of clinical measurement CVP.But the method is subject to the interference of anthropic factor, and science, standard, rigorous fixed zero method are quite important.
Yet regrettably, what still lack at present science decides the odd-job tool, and mostly clinical nurse is to carry out according to ocular estimate the step of zeroing, and poor reliability is easy to cause error.
Summary of the invention
The aid of zeroing when the purpose of this utility model is to provide a kind of CVP of survey is to get rid of the range estimation error at zero point.
In order to achieve the above object, the technical solution of the utility model has been to provide a kind of central venous pressure balancing, it is characterized in that: comprise the device body, be formed with a draw-in groove that is used for placing tube for transfusion in the front of device body, be positioned on the part of draw-in groove both sides at the device body and be formed with respectively a reading ruler, the left and right sides at the device body is respectively equipped with an expansion link, during use, it is vertical that expansion link and the reading ruler of homonymy are 90 degree, and the home position of 0 position in reading ruler and expansion link termination is located along the same line.
Preferably, be respectively equipped with one in the both sides of described device body for the playback groove of taking in described expansion link.
Preferably, be provided with fixed mount at the back side of described device body.
Preferably, be provided with fixedly leaf of two tube for transfusions in the front of described device body, lay respectively at top and the below of described reading ruler.
As stated in the Background Art, when lacking at present clinically the survey CVP of science, zeroing instrument used, be to estimate to carry out the step of zeroing by the nurse substantially.And measure CVP, and zeroing is a vital step, being directly affects a step of accuracy as a result.For guarantee the accurate of reading as far as possible, reduce error, the nurse must keep half crouch, sight is patrolled shuttle to align zero point back and forth in pressure measurement pipeline zero point and patient's midaxillary line the 4th rib level, but with the distance between patient's arm, a part of bed, drip stand also between the pressure measurement pipeline, all too easily causes personal error due to patient's midaxillary line.Gently affect patient's normal therapeutic, heavy delay patient's rescue, threat to life.Stress in the medical treatment, care environments of " safety " in our everything, not rigorous like this, nonstandard situation should not occur really.Medical treatment is flourishing, and our nursing means also should follow up in big strides.Therefore, the appearance of the instrument of the measurement CVP of science, rigorous, standard is actually a very urgent problem.This utility model is set about from a clinical line just for this situation, solves the problem that urgent clinical needs solve.
When this utility model is surveyed CVP for the nurse, zeroing provides a kind of aid, and is time saving and energy saving, and gets rid of the range estimation error at zero point, ensures patient medical and nursing safety.
Description of drawings
The front view of a kind of central venous pressure balancing that Fig. 1 provides for this utility model;
The rearview of a kind of central venous pressure balancing that Fig. 2 provides for this utility model.
The specific embodiment
For this utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figures 1 and 2, this utility model provides a kind of central venous pressure balancing to comprise fixedly leaf 7 of device body 1, draw-in groove 2, reading ruler 3, expansion link 4, playback groove 5, fixed mount 6 and tube for transfusion.
The draw-in groove 2 that is used for the placement tube for transfusion is opened in the front of device body 1, and the reading ruler 3 at the both sides of draw-in groove 2 band scale is 0-30cm, and pressure measurement can directly be carried out reading after finishing.At the fixing leaf 7 of each tube for transfusion up and down of reading ruler 3, under minimum and maximum reading, do not affect reading respectively, can 360 degree rotations, be used for after tube for transfusion is put into draw-in groove 2, it being fixed maintenance tube for transfusion smooth, distortionless.At each expansion link 4 of both sides of device body 1, expansion link 4 can rotate freely, and length can be by with its flexible adjusting, after it is put down, automatically with reading ruler 3 be 90 ° vertical, the home position of 0 position of reading ruler 3 and expansion link 4 terminations is at a straight line.At each playback groove 5 of both sides of device body 1, expansion link 4 not the used time or be finished after be placed in playback groove 5, be hidden in reading ruler 3, increase attractive in appearance.This utility model can be fixed on an other drip stand degree of tightness scalable by fixed mount 6.
During hand dipping CVP, first use this utility model to determine dead-center position (measuring CVP as example with horizontal position):
1, this utility model is fixed on drip stand, does not need too tightly, fixing a little, it is not slided up and down get final product.
2, shake the level bed head, make the patient flat sleeping, advise patient's both hands to encircle, with exposure midaxillary line the 4th intercostal (right atrium level) position.
3, put down the expansion link 4 of close patient's one side, according to the length of distance minor section telescopic bar 4.
4, slightly loosen fixed mount 6, this utility model is moved up and down, with the center of circle (being dead-center position) aligning patient midaxillary line the 4th intercostal with expansion link 4 tops, then the frame 6 that is tightened, fully fixedly this utility model, decide zero step and complete.
5. with expansion link 4 returns.
6. will insert in draw-in groove 2 with atmosphere phase go side infusion pipeline, close fixedly leaf 7 of two of up and down tube for transfusion, maintenance pipeline smooth, distortionless.
7. step is carried out pressure measurement routinely.
8. carry out reading by draw-in groove 2 other scales, be the CVP value.
