Description
Technical field
The invention belongs to technical field of medical instrument more particularly to a kind of novel all-in-one central vein pressure measuring unit and make
Use method.
Background technique
Currently, the prior art commonly used in the trade is such that
Central venous pressure (CVP) refers to the pressure of superior vena cava or inferior caval vein, is that patient with operation or Cavity in Critical Patients are normal
Monitoring index.Central venous pressure reflects survey the pressure effective blood volume of patient, heart function and blood vessel at that time to a certain extent
The integrated status such as tension.Therefore, METHOD FOR CONTINUOUS DETERMINATION central venous pressure, can dynamic knowledge blood volume variation and judge heart to fluid infusion
Tolerance, be adjust infusion treatment an important reference indicator.
Measuring center vein pressure is mainly the following method: one is with easy central vein pressure measuring unit measure,
Using commonplace；One is surveying to press by energy converter, specific apparatus is needed, application is less.Application now it is wider it is simple in
Cardiac vein pressure measuring unit is respectively: perfusion tube, extension tube and three-way cock, this three sampling device is connected when surveying pressure, also
It is to say that several devices are independently from each other.And extension tube and pipe cap non-integral, measurement process need to remove pipe cap.In addition it measures
When need with dedicated central vein nose bar come reading numerical values.
This mode in operating process because three kinds of devices are taken out in different packaging bags, then again one by one
Connection, increases certain workload；In the process of handling, it is likely to result in the pollution of device, increases nosocomial infection
Chance；It is possible to loosen between each device connected in the process used, causes the bad thing such as air embolism or bleeding
Part causes serious consequence for patient, so there is potential unsafe factor.Meanwhile pressure-measuring pipe and pipe cap non-integral, it surveys
Amount process is repeated multiple times to remove pipe cap, is easy to fall or pollute.In addition, measurement process needs also to increase using dedicated measuring scale
Add operating procedure, influenced the accuracy of working efficiency and reading, and increases medical department cost.
In conclusion problem of the existing technology is:
1 in the measurements calm pulse pressure when, need to assemble in multiple devices, increase workload, influence working efficiency,
A possibility that increasing device pollution, is unfavorable for the prevention and control to nosocomial infection；
2 are likely to occur de- pipe in the process used, and safety is low.
3 extension tubes and pipe cap non-integral, measurement process is repeated multiple times to remove pipe cap, and pipe cap is easy to fall or pollute.
4 measurement process need to increase operating procedure using dedicated measuring scale, influence the accurate of working efficiency and reading
Property, and increase medical department cost.
Summary of the invention
In view of the problems of the existing technology, the present invention provides a kind of novel all-in-one central vein pressure measuring unit and make
Use method.
The invention is realized in this way a kind of novel all-in-one central vein pressure measuring unit is provided with
Three-way cock；
Three-way cock upper end is connected with the perfusion tube of integrated molding, and Murphy's dropper, Murphy are connected among perfusion tube
Dropper lower end outside is equipped with speed-regulating switch；
Three-way cock side is provided with the extension tube of integrated molding；
The upper end of three-way cock is connected to general infusion connector.
Further, extending pipe outer wall has graduation mark.
Further, general infusion connector is connect with other infusion devices.
Further, extension tube is integrated with pipe cap, and when measurement removes pipe cap, and pipe cap is avoided to fall or pollute.
Another object of the present invention is to provide a kind of application method of novel all-in-one central vein pressure measuring unit,
The application method of the novel all-in-one central vein pressure measuring unit includes: when in use, to pass through the general of three-way cock lower end
Infusion connector is connect with Central catheterization, is rotated three-way cock, is connected to perfusion tube with extension tube, and pipe cap is opened, and liquid level exists
Rise in extension tube, adjusts speed-regulating switch and the liquid level in extension tube is made to be higher than the actual CVP value of patient, while cannot be from extension
The outflow of pipe upper end tube nozzle.
In conclusion advantages of the present invention and good effect are as follows:
The present invention can be connected by the way that perfusion tube, extension tube and three-way cock are carried out integration by three-way cock
The treatment such as other infusion devices are connect, while carrying out venous transfusion, in use, being not have to each device carrying out group respectively first
Dress, reduces the operating time of medical worker, improves working efficiency, avoids the possibility polluted in an assembling process.Second
De- pipe will not occur for use process, increase safety.Third extension tube is equipped with integrated pipe cap, and when measurement removes pipe cap, keeps away
Exempt from pipe cap to fall or pollute.4th uses graduated pressure-measuring pipe, simplifies work step, improves working efficiency, improves reading
Accuracy, lower medical department cost.
