The beneficial effects of the utility model are that, rely on the straight line propagation of light, only need open laser emitter's switch when the location, when atrium dextrum middle part (midaxillary line fourth intercostal) was aimed at to laser emission's luminous point, expression " school zero " was successful.
Description
Technical field
This utility model relates to technical field of medical instruments, specifically a kind of central venous pressure tester.
Background technology
Central venous pressure (central venous pressure, CVP) refers to right atrium and upper and lower chamber
The pressure of vein thoracic cavity section.It can determine whether the comprehensive condition of Blood of Patients capacity, cardiac function and antiotasis,
It is different from peripheral venous pressure.CVP measures and is usually used in: 1. acute heart failure；2. a large amount of transfusions or the heart
During dirty patient infusion；3. when critical patient or cardiopulmonary bypass surgery.The normal value of central venous pressure is
6-12cmH2O, reducing or increase central venous pressure value all has important clinical meaning.
For measure the measurement of central venous pressure pipe of central venous pressure zero point must with right atrium in the middle part of
(midaxillary line the 4th intercostal) in same level, during position variation, should again " school zero ", otherwise can shadow
Ring the correctness of reading, thus affect the accuracy of result.Clinically, often change due to patient
Clinostatism or the height of adjustment sick bed, will pass through nurse with the naked eye when causing measuring central venous pressure every time
Observe, to adjust the dead-center position of measurement of central venous pressure pipe in time.But, in practical operation,
Accomplish the most smart for three in the middle part of the sight line of nurse, the zero point of measurement of central venous pressure pipe, right atrium
Really keep difficulty in the same horizontal line the biggest.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that one is easy in nurse general
In the middle part of the zero point of calm pulse pressure mensuration pipe and right atrium, (midaxillary line the 4th intercostal) keeps in same level
Pressure tester at same level line.
In order to achieve the above object, this utility model provides a kind of central venous pressure tester, bag
Including graduated tile and fixed support, described graduated tile is provided with zeromark bar, and this graduated tile is at Vertical Square
To being provided with measurement of central venous pressure pipe, on fixed support described in described graduated tile right angle setting,
Generating laser, this generating laser place straight line and zeromark are installed on described graduated tile
Bar place straight line is on same level line；
Described generating laser connecting valve.
Preferably, groove is offered at described zeromark bar；
Described generating laser is arranged in this groove.
Preferably, described fixed support is hydraulic support, and it is vertically provided with track, institute
State graduated tile to be arranged in this track；
Described support bracket fastened bottom is provided with the pedal suitable with hydraulic means.
Preferably, the scale range of described graduated tile is-3～30cm.
The beneficial effects of the utility model are, rely on the straightline propagation of light, only need to open when location
The switch of generating laser, in the middle part of the spot alignment right atrium of Laser emission (midaxillary line the 4th intercostal)
Time, represent " school zero " success.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
Embodiment 1:
A kind of central venous pressure tester as shown in Figure 1, including graduated tile 1 and fixed support 2,
Described graduated tile 1 is provided with zeromark bar 11, and this graduated tile 1 is provided with central vein in vertical direction
Pressure measures pipe 12, on fixed support 2 described in described graduated tile 1 right angle setting,
Generating laser 3, this generating laser 3 place straight line and zero point are installed on described graduated tile 1
Scale strip 11 place straight line is on same level line；
Described generating laser 3 connecting valve 4.
Groove 5 is offered at described zeromark bar 11；
Described generating laser 3 is arranged in this groove 5.
Described fixed support 2 is hydraulic support, and it is vertically provided with track 21, described quarter
Degree plate 1 is arranged in this track 21；
The bottom of described fixed support 2 is provided with the pedal 6 suitable with hydraulic means.
The scale range of described graduated tile 1 is-10～30cm.
Actually used example:
1, the selection of vein indwelling ways: 1. percutaneous puncture method: through subclavian vein or right internal jugular vein
Puncture cannula is to superior vena cava, or intubates to postcava through femoral venous puncture.It is generally acknowledged through epicoele
Vein pressure measurement is relatively more accurate through postcava pressure measurement.2. venotomy method: the most more lack use, only use
In intubating to postcava through incision of great saphenous vein.Or because blood volume is low, blood pressure low cause vasoconstriction,
Full bad, cause repeated localised puncture loser.
2, the connection of central venous pressure tester: one end of three-way cock is connected with intravenous transfusion device
To connect venous transfusion, the other end is connected with central vein catheter, the center on one end and graduated tile 1 again
Measurement of venous pressure pipe 12 is connected.
3, the mensuration of central venous pressure: before pressure measurement, first connects flat by the threeway port of connecting intravenous infusion
Weighing apparatus liquid, to rinse venous channel and measurement of central venous pressure pipe 12.Patient's horizontalization clinostatism, by switch
4 open generating laser 3, are carried out the graduated tile 1 in fluctuating orbit 21 by foot-treadle 6, make to swash
Laser alignment patient's midaxillary line the 4th intercostal that optical transmitting set 3 is launched, now " school zero " success.
Regulation threeway, makes central vein catheter communicate with measurement of central venous pressure pipe 12, now central venous pressure
The liquid level measured in pipe 12 can fluctuate up and down, when liquid fluctuating is in a fixed range, and central venous pressure
In mensuration pipe 12, the scale corresponding to liquid level is CVP.When stopping pressure measurement, regulate threeway, make vein
Transfusion device communicates with central vein catheter, continues fluid infusion.School zero will be carried out before pressure measurement every time.Pressure measurement
Blow back into the blood in measurement of central venous pressure pipe 12 need to rinse well, keep pipeline unobstructed.
Below the preferred embodiment created this utility model is illustrated, but this practicality is new
Type is created and is not limited to described embodiment, and those of ordinary skill in the art are new without prejudice to this practicality
Modification or the replacement of all equivalents, these equivalent modifications can also be made on the premise of type creative spirit
Or replacement is all contained in the application claim limited range.
