A kind of novel and multifunctional pressure-measuring pipe of the utility model, when measuring intravesical pressure, first, patient lies down, sterile
The lower per urethra bladder insertion Forley urinary catheters of operation, empty bladder；Novel and multifunctional pressure-measuring pipe lowermost end zero graduation point is adjusted to
With same level at the midaxillary line of patient, secondly, valve tee pipe 3 is adjusted to water filling port and communicated with pressure measurement end 1-1, injection temperature
Salt solution 25-50 milliliters, rotating band valve three-way pipe 3 to pressure measurement end 1-1 communicate with connection end 1-2, connection end 1-2 and L-shaped graded tube 2
Connection, liquid are flowed out in L-shaped graded tube 2, the position that observation fluid level stops, being defined by patient expiration end, liquid level
As intravesical pressure, reading reference units are mmHg., can be first by 2ml physiological saline syringes if intravesical pressure is negative pressure
U-shaped negative value pressure-measuring pipe 1 is injected from valve tee pipe 3, it is in integrally vertical state only to keep pressure-measuring pipe with U-shaped negative value pressure-measuring pipe 1, because
Intravesical pressure can attract physiological saline in pressure-measuring pipe to be moved into bladder, it will be seen that liquid level declines in vertical graded tube, works as water
Post stops declining, and now the scale value of liquid level is intravesical pressure in vertical graded tube.
A kind of novel and multifunctional pressure-measuring pipe of the utility model, in the measurements during calm pulse pressure, first, patient lies down, in nothing
Bacterium operation covers closure plug 4, by short end and center with the short end saline injection of L-shaped graded tube 2 to the top of L-shaped graded tube 2
Ductus venosus is connected, and novel and multifunctional pressure-measuring pipe lowermost end zero graduation point is adjusted into same level at the midaxillary line with patient,
Open closure plug 4, the position that observation fluid level stops, the midpoint with breathing fluctuation up and down is central venous pressure, reading
Reference units is cmH2O。
A kind of novel and multifunctional pressure-measuring pipe of the utility model, when measuring cerebrospinal pressure, 0- is carved with L-shaped graded tube 2
39cmH2O scale, -5-0cmH is carved with U-shaped negative value pressure-measuring pipe 12O scale.By U-shaped negative value pressure measurement after lumbar puncture success
The pressure measurement end 1-1 of U-shaped negative value pressure-measuring pipe 1 is connected to puncture needle tail end after pipe 1 and the connection of L-shaped graded tube 2, keeps pressure-measuring pipe vertical
State, if intracranial pressure is more than zero, cerebrospinal fluid flows into U-shaped negative value pressure-measuring pipe 1 and can see water column on vertical graded tube
Liquid level, when water column stops rising, liquid level scale is intracranial pressure.If encephalic is negative pressure, lose brain after puncturing successfully
Spinal fluid flows out, and 2ml physiological saline syringe first can be injected into U-shaped negative value pressure-measuring pipe 1 from valve tee pipe 3, only with U-shaped negative value
It is in integrally vertical state that pressure-measuring pipe 1, which keeps pressure-measuring pipe, because encephalic negative pressure can attract physiological saline in pressure-measuring pipe to be moved into Lumbar catheter
It is dynamic, it will be seen that liquid level declines in vertical graded tube, when water column stops declining, now in vertical graded tube liquid level scale
Value is intracranial pressure.
A kind of novel and multifunctional pressure-measuring pipe of the present utility model carries two kinds of scales, is not required to prepare ruler, can be read required
Unit reading, is easy to clinical reference；Meanwhile U-shaped negative value pressure-measuring pipe can measure negative pressures that may be present, can measure wing
Pressure, the numerical value of cerebrospinal pressure and negative pressures numerical value that may be present in Guang, can also measuring center vein pressure, measurement
Precision is high.The pressure-measuring pipe is split type, in the measurements during calm pulse pressure, can save U-shaped negative value pressure measurement tube portion, is saved
Production cost, it is cheap；One-way air filter screen is set in the pressure-measuring pipe, environmental contaminants can be hindered into pressure-measuring pipe
Every；The special construction of the closure plug, the groove and plug neck for making plug bizet form dual pressure holding effect simultaneously, moreover it is possible to rise
To the effect for preventing plug jumping.
Above disclosed is only preferred embodiment of the present utility model, certainly can not be new to limit this practicality with this
The interest field of type, therefore the equivalent variations made according to the utility model claims, still fall within what the utility model was covered
