Description
Technical field
This utility model is related to a kind of urodynamic study conduit, particularly one kind can with Simultaneous Determination intravesical pressure and
The two-chamber urodynamicss pressure catheter of different parts urethra pressure.
Background technology
Urinary functional test is the cross discipline of modern medicine, biofluid mechanics, Biorheology, is widely used in urinary tract
The basic research of many diseases such as obstruction, urinary incontinence and other urinary dysfunctions, diagnosis, treatment and therapeutic evaluation, with urinary system
The specialty such as surgery, department of obstetrics and gynecology, department of pediatrics, department of endocrinology, Neurology Department, anorectum department is closely related.
At present, conventional Urinary functional test index measured directly is bladder and internal rectum pressure, urinary flow, urine volume.The most normal
It is invasive urodynamic study method：The insertion intravesical pressure change of pressure-measuring pipe direct measurement, measures uroflow simultaneously
Rate；It is analyzed using AG, PQ figure, diagnose the illness.
Urine power inspection not only needs to cystometry, is also required in many cases to urethra pressure measurement.Generally, urinate
It is prostate region that road resistance mostlys come from urethra near-end.But as there is urethral stricture, then urethral resistance may be from urinating
Any position in road.So, there is clinical meaning to urethra different parts pressure measurement.Existing measurement urethra pressure method, is that constant speed is led
Draw pressure-measuring pipe measurement each section of pressure distribution situation of urethra of constant current perfusion.But, the method Shortcomings of existing measurement urethra pressure.
At present the method for general measure urethra pressure can not synchronous with bladder pressure be carried out, and cannot monitor bladder pressure in the phase of urinating
While measure urethra pressure.So can not completely embody the pressure change of bladder and urethra during urinating.In the conventional method,
As synchro measure bladder pressure and urethra pressure, need to put pipe, independent measurement urethra pressure in urethra again.In this case, urinate
There will be 3 in road and check chambeies (perfusion path, cystometry path, urethra pressure measurement path), check that pipeline will be relatively thick, to urinating
Interference is too big, the accuracy that impact checks.
Existing method is also not easy to measure the pressure of urethra any part.Because urethral stricture can occur appointing in urethra
Meaning position is it is sometimes desirable to understand the pressure change of urethra different depth, this requires for another urethra pressure-measuring pipe to be placed on urethra
Different depth.Narrow and small in view of urethra tube chamber, this operation is very not convenient, easily stimulates patient to produce pain, and is easier
Produce the complication such as bleeding, infection.
For existing disadvantage, there are 3 inspection chambeies especially for external orifice of urethra, cause interference with the defect urinated, need
A kind of new urodynamicss pressure catheter is provided, above-mentioned technical problem can be overcome, complete when measuring intravesical pressure, measurement urine
The pressure measurement of different parts in road.
Content of the invention

Ring.
This utility model provides a kind of two-chamber urodynamicss pressure catheter, and described peelable epitheca is provided with scale.
This utility model provides a kind of two-chamber urodynamicss pressure catheter, and one end of described peelable epitheca can connect urethra
Internal pressure measurement device.
Problem to be solved in the utility model is exactly：
In two-chamber urodynamicss pressure catheter of the present utility model, by controlling position in urethra for the peelable epitheca,
The cavity being formed between bladder piezometer tube and peelable epitheca (can be urinated by irrigating path (perfusion phase) and be changed into pressure measurement path
Phase), therefore need not separately set pressure measurement path.The less diameter of two-chamber urodynamicss pressure catheter still can be kept, minimum to interference of urinating.
Two-chamber urodynamicss pressure catheter of the present utility model can realize synchronous intravesical pressure and variant position urine
The intrinsic pressure mensure in road.
Two-chamber urodynamicss pressure catheter of the present utility model, operational approach is simple.By by peelable epitheca from urethra
Middle extraction, controls position in urethra for its one end, the device for casting of filling apparatuss is replaced by the urethra of the phase of urinating intrinsic pressure simultaneously
Measurement apparatus.

Specific embodiment
In conjunction with specific examples below and accompanying drawing, this utility model is described in further detail.Implement this utility model
Process, condition, experimental technique etc., in addition to the following content specially referring to, be this area universal knowledege and known often
Know, this utility model is not particularly limited content.
As shown in figure 1, the schematic diagram of the two-chamber urodynamicss pressure catheter for the present embodiment.The two-chamber urine of the present embodiment is dynamic
Mechanics pressure catheter, including intrusion pipe 1, bladder piezometer tube 2；Peelable epitheca 3.Bladder piezometer tube 2 is set in peelable epitheca 3
In, form cavity 4 between bladder piezometer tube and peelable epitheca.Cavity 4 the irrigation of bladder phase as perfusion path, in the phase of urinating
As the intrinsic pressure measurement path of urethra.Partly or entirely peelable epitheca 3 can be slided along bladder piezometer tube 2 and be pulled out urethra 6.Wing
One end head 21 of Guang pressure-measuring pipe 2 is exposed from one end of peelable epitheca 3, and the other end 22 of bladder piezometer tube 2 is from outside peelable
The other end of sheath 3 extends outside urethra 6, and is connected with bladder pressure measuring device (not shown).One end of intrusion pipe 1 is from peelable
In the other end insertion cavity 4 of epitheca 3, the other end extends from the other end of peelable epitheca 3, with device for casting (not shown)
Connect.It is provided with scale, for marking position in urethra 6 for the peelable epitheca 3 on peelable epitheca 3.
As shown in Fig. 2 being in the irrigation of bladder phase, the two-chamber urodynamicss pressure catheter of the present embodiment perspective in bladder
Schematic diagram.As shown in figure 3, the perspective enlarged diagram for part A in Fig. 2.As illustrated, the cross-sectional area of bladder piezometer tube 2
For semi-circular shape.In the irrigation of bladder phase, one end 21 of bladder piezometer tube 2 is exposed from one end of peelable epitheca 3, positioned at bladder 5
Interior position.The other end 22 of bladder piezometer tube 2 then extends outside urethra 6 from the other end of peelable epitheca 3, with cystometry
