Abstract
A test method used in bio-kinetics for measuring the kinetic parameters of living things features use of a constant-speed perfusion method combining pressure- measuring inject with pressure-measuring perfusion. Its apparatus is composed of pressure measuring tube and constant-speed perfusion unit connected to injector and motor drive mechanism.
Description
Technical field
The invention belongs to medical testing equipment, be used for the dynamics of living body inspection
Background technology
The dynamics of living body inspection is a subdiscipline of Urology Surgery and division of gastroenterology, it is according to hydrodynamics and electrophysiological ultimate principle and method inspection gastrointestinal and urinary tract each several part pressure, flow rate and bioelectric, thereby understand living body functional and mechanism, and the pathobiology of functional disorder disease changes.Need to test the various indexs of urine power and digestive tract power with organism dynamometry instrument for this reason.Existing gauge such as patent ZL02149744 " noinvasive urine pump dynamograph ", it is by the harmless medium of injection in venous patient, and utilize a plurality of Type B ultrasonic probes to survey patient from different perspectives at storage urine with the bladder when urinating and the situation of urethra, the information that B ultrasonic detects is passed through image pick-up card, gather and be stored to microcomputer entirely dynamically, by software processes, realize that patient stores urine and the dynamic attention of the 3D animation after bladder and the urethra situation when urinating.
This instrument test is accurate, but its needs to the venous patient injected media, is difficult for being accepted by patient, and its equipment is huge simultaneously, production cost is high, and price is expensive, is difficult for applying.Carry out the tract pressure measurement, be that pressure catheter is inserted in the tract the simplelyst, most economical, carries out pressure measurement.In order to measure the pressure of tract, and obtain a successive pressure curve, all adopt constant speed tract perfusion manometric technique clinically.
Mainly form by accompanying drawing 1 visible perfusion technique pressure measurement instrument by the charge pump that pressure-measuring pipe 1, constant speed intrusion pipe 2, rotating axle 4 and perfusion medium inlet 3 constitute, pressure-measuring pipe is a T type pipe, T type two-port connects tract and pressure transducer respectively, the 3rd port is connected with a port of constant speed intrusion pipe, and the another port of constant speed intrusion pipe connects the charge pump outlet.During pressure measurement, the pressure measurement medium is injected by charge pump inlet (perfusion medium inlet 3), from charge pump outlet output, to pressure-measuring pipe 1, by pressure transducer, demonstrates successive pressure curve through constant speed intrusion pipe 2 through rotating axle 4, to obtain the pressure of tract each several part.The feature of this test instrunment is the special constant speed perfusion cannula of wheel shaft extruding that utilizes constant speed to rotate, and obtains pressure medium and enters the constant speed perfusion, and the rotating speed medium that changes wheel shaft can obtain different rate of floodings.When carrying out the urethra pressure measurement, the general rate of flooding that adopts 2～10ml/min, this rate of flooding belongs to the low speed perfusion (with respect to cystometry, during cystometry, the general rate of flooding perfusion of adopting 10～100ml/min), this testing equipment rotating axle is that dotted line contacts when pushing with perfusion cannula, again because of there being the foozle of parts, in the test filling process, there is the extruding discontinuity in rotating axle when extruding constant speed perfusion cannula, can occur in the inside of perfusion medium than great fluctuation process for this reason, be delivered to pressure measurement place of pressure-measuring pipe by the liquid road, stress test is produced influence of fluctuations.When wheel shaft rotates slowly, particularly evident to the medium fluctuation, thus have influence on the gaging accuracy of urethra.
Summary of the invention
The present invention is directed to the pressure medium fluctuation that the wheel shaft rotation brings in the charge pump, have influence on the problem of the gaging accuracy of tract, the special proposition with injecting manometric technique and charge pump manometric technique Application of composite in the kinetics inspection, and the testing equipment that realizes this technology is provided, to improve the gaging accuracy of tract.
The solution of the present invention is the constant speed perfusion manometry that adopts the technology of injecting and perfusion technique to combine, be about to pressure measurement medium filling bladder or perfusion urethra or perfusion gastrointestinal, and on the tester screen, show organism dynamic test index, or on recording equipment, write down index by pressure-measuring pipe and pick off.For realizing this method, the invention provides new dynamic test equipment.This testing equipment is made up of T type pressure-measuring pipe and constant speed pouring member, and the two-port of T type pressure-measuring pipe connects urethra respectively to bladder and pressure transducer, and the 3rd port connects the constant speed pouring member.The constant speed pouring member connects syringe 8 by constant speed intrusion pipe 2 and motor transmission mechanism 9 (being the charge pump interface) is formed (seeing accompanying drawing 2).During low speed perfusion test, in the pressure medium inhalation syringe 8, rotate drive transmission mechanism 9 pushing syringes by motor, pressure medium in the syringe is entered in the body cavity of organism through constant speed intrusion pipe 2 to T type pressure-measuring pipes, again along direction 5 constant speed traction pressure-measuring pipe, show test index after pressure transducer A/D sampling on the tester screen, this belongs to the technology of injecting.When pouring into pressure measurement at a high speed, pressure medium then by charge pump inlet 3 perfusion media, exports to constant speed intrusion pipe 2 through rotating axle 4 from charge pump, enter in the body cavity of organism by pressure-measuring pipe again, after pressure transducer A/D sampling, on the tester screen, show test index, this belongs to perfusion technique.
After the present invention adopted the technology of injecting and conventional perfusion technique to combine, the more existing method of testing of the parameter that tests out was more accurate, and the device fabrication cost is not high, helps the market demand.

Embodiment:
The measurement device of the measurement urinary tract pressure that technology and perfusion technique combine is injected in employing, selects for use non-toxic biocompatible material to make pressure-measuring pipe.The constant speed intrusion pipe selects for use silica gel material to be made into aperture 8mm, the bend pipe of long 300mm, syringe 50ml model.Motor is selected Japanese import motor for use, is connected with syringe by the worm and gear transmission, each parts is pressed Fig. 2 assembling get final product.
Measure urethra pressure, adopt the technology of injecting during low speed perfusion pressure measurement, at first with in the pressure medium inhalation syringe, the one port insertion urethra of the pressure-measuring pipe in the measuring device 1 is directly arrived bladder, the another port connects pressure transducer, starter motor transmission mechanism 9, pushing syringe 8, pressure medium is guaranteed the 2ml/min rate of flooding, to pressure-measuring pipe 1, pour into to urethra through constant speed intrusion pipe 2, again along lead 5 constant speed traction pressure-measuring pipe, pressure medium in the pressure-measuring pipe behind pressure transducer A/D, shows test index on the tester screen.
When non-low speed pours into pressure measurement, adopt perfusion technique, the constant speed pouring member turns to charge pump injection pressure medium automatically, and pressure medium enters into pressure-measuring pipe 1 through charge pump to the constant speed intrusion pipe, and the flow process behind pressure-measuring pipe is identical with the technology of injecting.
