Abstract
The utility model relates to a disposable central vein pressure-measuring pipe can freely adjust zero point from top to bottom, and easy operation and result are accurate reliable, reduce iatrogenic and infect. And the dynamic monitoring can be frequently carried out for a plurality of times, so that the economic burden of the patient is reduced. When in use, one end of the three-way pipe (5) is connected with the main channel of the clavicle lower end interface (6), and the other end is connected with the conventional liquid end interface (4). When CVP measurement is needed to be carried out on a patient, the three-way pipe (5) is rotated, the opening of the three-way pipe (5) at the upper end is opened to be communicated with the atmosphere, and then the conventional liquid end interface (4) is closed to suspend transfusion. Rotating the three-way pipe (5) to communicate with the lower end interface (6) of the clavicle, straightening to keep the position (3) of the 0 point in a vertical state, and reading and recording the numerical value after the liquid level is kept stable.
Description
Technical field
This utility model relates to a kind of disposable central venous piezometric tube, freely up and down can regulate zero point, and simple to operate and result accurately and reliably, reduces nosocomial infection.Also can frequently repeatedly dynamic monitoring, alleviate patient economy burden.
Background technology
Usually there is following problem during the disposable central vein of current clinical measurement: 1, complicated operation and result poor accuracy, easily cause nosocomial infection.2, be difficult to differentiate during sewing needle urgent need, waste time and energy.3, efficiency of trying to make a match is low, inconvenient patient's operation.
Summary of the invention
The stitching thread usually existed for the management overcoming clinical suture easily come off knotting and sewing needle urgent need time be difficult to resolution, the problem such as waste time and energy, this utility model provides a kind of disposable central venous piezometric tube, freely up and down can regulate zero point, simple to operate and result accurately and reliably, reduces nosocomial infection.Also can frequently repeatedly dynamic monitoring, alleviate patient economy burden.
The technical scheme that this utility model adopts is: disposable central venous piezometric tube is characterized in that this device is inverted T-shaped slender pipeline, top is logical air pipe (1), stage casing is normal range value (2), what the below of normal range value (2) was adjacent is 0 position (3), inverted T-shaped pipe connect tee T (5) bottom, plumbness is kept with 0 position (3), the left side of tee T (5) connects conventional liq end interface (4), and the right side of tee T (5) connects end interface (6) under clavicle.
The beneficial effects of the utility model are: a kind of disposable central venous piezometric tube, freely up and down can regulate zero point, and simple to operate and result accurately and reliably, reduces nosocomial infection.Also can frequently repeatedly dynamic monitoring, alleviate patient economy burden.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, this utility model is further illustrated.Fig. 1 is disposable central venous piezometric tube schematic diagram.In figure 1, logical air pipe; 2, normal range value; 3,0 position; 4, conventional liq end interface; 5, tee T; 6, end interface under clavicle.
Detailed description of the invention
In embodiment shown in the figure, when disposable central venous piezometric tube uses, tee T (5) one end is connected with the main channel of end interface under clavicle (6), other end conventional liq end interface (4).When needing to carry out CVP measurement to patient, swivel tee pipe (5), tee T (5) opening opening upper end connects air, then closes conventional liq end interface (4) and suspends transfusion.Swivel tee pipe (5), makes it communicate with end interface under clavicle (6), stretchingly makes 0 position (3) keep plumbness, until liquid level keep stable after reading numerical values record.
Although shown detailed embodiment of the present utility model above, obviously, those skilled in the art without prejudice under prerequisite of the present utility model, can carry out part modifications and changes; The content mentioned in description above and accompanying drawing only illustratively illustration, not as to restriction of the present utility model, has the disposable central venous piezometric tube of above-mentioned technical characteristic, all falls into protection domain of the present utility model.
Claims (1)
