Description

A kind of Spatial Multi-Dimensional biology loine pressure detection probe applied to urinary system and System

Technical field

Technical field of medical instruments is the utility model is related to, specifically, is related to a kind of space applied to urinary system Multiple-biological loine pressure detection probe and system.

Background technology

Pressure detecting in biological cavity is a kind of important technology for being widely used in clinical diagnosis and biological study.Biology Cardio-cerebrovascular, urinary system, digestive system and reproductive system of body etc. all have a pipe structure, and pressure detection technology can be with It is strong and weak by the pressure of sensor senses intracavitary, understand the change of its internal drag.In clinical diagnosis, reliable pressure detecting As a result can help to judge whether the abnormal conditions such as luminal stenosis, surrounding tissue compressing and inwall diverticulum, and to subsequently controlling The development for the treatment of provides important evidence.In biological research fields, it can be additionally used in the pathophysiological basis for exploring disease.

In general, manometric technique is mostly the pressure of axially one-dimensional upper single channel in currently used biological cavity Perceive.So that intraurethral pressure determines as an example, this method is to be taught to invent in 1969 by Brown and Wickman two, and one Directly use till today.Its principle is that a pressure-measuring pipe per urethra with side opening (single hole or symmetrical diplopore) is inserted into bladder, The water filling into pipe by constant speed charge pump, while outwards pull conduit along urethra major axis using a constant speed tractor.Work as pressure measurement Conduit side opening from bladder enter urethra when, due in urethral wall muscle contralateral exposure current project generate resistance, cause pressure Change.Thus, while pressure-measuring pipe slowly outwards removes, the upside from urethra near-end to distal end different level can be measured The pressure change of some specific region where hole, finally depict a continuous curve.This method is extensive always Assessment for clinical urethra closing function and urethral resistance.In addition, what the piezometry of other cavities used is also class As single-sensor manometric technique, such as differing only in it uses for the piezometry in anal orifice and rectal intestine and above-mentioned urethra pressure measurement It is special foley's tube and medium is used as using water or air.

However, present inventor in long-term research work, carefully analyzes and thought deeply summary, it is understood that existing survey Press technical notes to actually in tube chamber on certain cross section single orientation pressure value, and with it come it is approximate represent it is axial one-dimensional In the point pressure condition, therefore its accuracy and repeatability be not good enough.First, its testing result is by pressure tap space side To the influence of torsion, such as, if the side opening of pressure-measuring pipe understands the shadow by pubic symphysis towards veutro during outside drawing Ring, the pressure value measured can be higher, conversely, relatively low towards institute's measured value during dorsal part.Secondly, it is only capable of roughly reflecting in tube chamber Resistance change, but cannot make out the change in tube chamber the location of on three-D space structure, for example, the side of tube wall by External world's compressing and occur narrow, can only observe that lesion Resistance Value raises extremely, and can not sentence using traditional manometric technique Break the relation of the extraneous oppressive force and tube chamber all around wall.Therefore, it is necessary to research and develop new biological cavity manometric technique The accuracy of existing method is improved with device, preferably instructs the development of successive treatment.

The content of the invention

The purpose of this utility model is to be directed to deficiency of the prior art, there is provided a kind of space applied to urinary system is more Tie up biological loine pressure detection probe.

Another object of the present utility model is to provide a kind of Spatial Multi-Dimensional biology loine pressure applied to urinary system and examined Examining system.

Described axially spaced quantity is the integer more than or equal to 2.

Described body proximal face is curved.

To realize above-mentioned second purpose, the utility model adopts the technical scheme that：

A kind of Spatial Multi-Dimensional biology loine pressure detecting system applied to urinary system, it is characterised in that provided with wriggling Pump, feed tube, fluid reservoir, Data collecting and analysis system, tractor and as above any described Spatial Multi-Dimensional biology pipeline pressure Power detection probe；Each pressure conduction passage of described Spatial Multi-Dimensional biology loine pressure detection probe respectively correspond to one it is compacted Dynamic pump and feed tube；Described feed tube is installed on peristaltic pump, and one end is passed through fluid reservoir, and the other end is passed through pressure conduction passage It is interior；Described Spatial Multi-Dimensional biology loine pressure detection probe distal end is fixed on tractor；Described peristaltic pump connection data Collection and analysis system.

The utility model advantage is：The utility model proposes a kind of the general of brand-new axial space multidimensional pressure measure Read, axially refer to pressure tap moving along biological lumen major axis, Spatial Multi-Dimensional refers to horizontal to each tube chamber in moving process The pressure that section carries out 360 degrees omnidirection is perceived, and Spatial Multi-Dimensional biology loine pressure inspection of the present utility model is devised based on this Probing head and system, it can realize that progress multipoint pressure Simultaneous Determination, each pressure tap are right respectively on tube chamber difference cross section A curve is answered, more realistically reflects the pressure distribution situation of axial three dimensions in tube chamber, this method can improve existing inspection The accuracy and reliability of survey method, preferably instruct successive treatment, and important evidence is provided to establish precision clinical treatment.Tool Body：

1st, Spatial Multi-Dimensional pressure measurement helps to be accurately positioned lesion position, and excavates more with clinical correlation Parameter.For example, it is narrow to the cavity caused by the neoformation compressing outside tube chamber, can using Spatial Multi-Dimensional piezometry method To know which direction cambium comes to the main contention effect of tube wall exactly, oppressive force has more strong and compression sections Length etc., these indexs can be used in follow-up clinical treatment judging whether needs take operation, using which kind of operation, cut off Scope has the problems such as how wide；

2nd, it is separate between multiple passages in this pressure-measuring pipe, it can be compared, contribute between measured pressure value Pressure value caused by the artifact for avoiding single channel pressure measurement from occurring, such as tube chamber surrounding normal bony structure or physiological bending is inclined Move, improve the reliability and repeatability of inspection result.

As can be seen here, Spatial Multi-Dimensional biology loine pressure detection probe and system of the present utility model can be applied to people or dynamic The piezometry of a variety of biological cavities in thing body, diagnosis and animal experiment study to clinical disease are respectively provided with important value, Greatly improve the treatment level in related medical field.
