Abstract

A non-invasive urinary kinetic instrument for testing the function of urinary bladder and urethra is disclosed. A medium without damage to human body is injected into vein of patient and multiple B-type ultrasonic probes are used to detect the states of urinary bladder and urethra in the conditions of storing urine and discharging urine. The detected information is transmitted via image card to microcomputer, where said information is processed by software to dynamically reproduce the states of urinary bladder and urethra in 3D animation mode.

Description

Noinvasive urine pump dynamograph

Affiliated technical field

The instrument of the present invention's bladder that is a kind of patient of detection under the storage urine and the state of urinating and urethral function belongs to the Medical Instruments category, is to detect a kind of instrument that patient bladder and urethral function and bladder and urethral function under the storage urine and the state of urinating naturally are worked in coordination with situation.

Background technology

Present urine pump dynamograph has conventional and two kinds of twenty-four-hour urine pump dynamographs, the twenty-four-hour urine pump dynamograph is mainly used in the too urgent activity whether detection has bladder, thereby but the both will be inserted into pressure-measuring pipe patient's bladder is understood patient's bladder and urethra indirectly by pressure transducer mensuration pressure function.The twenty-four-hour urine pump dynamograph is to carry out under naturalness substantially, but belong to wound inspection is arranged, and promptly pressure-measuring pipe will be inserted into patient's bladder, with pure naturalness difference is arranged, and scope of application limitation, only is used to detect patient and whether has the too urgent activity of bladder.Conventional urine pump dynamograph, be that patient is fixed to a fixed position, generally be calculi position,, pour water to intravesical with certain speed then to patient's intravesical insertion pressure-measuring pipe, it generally is 50ml/ minute, pressure by in the pressure transducer detection patient's bladder requires controlled micturition, in the urine flow rate of the urinating instrument when patient need urinate, by the pressure of measuring patient's bladder and the variation of urinating flow rate, understand patient's the bladder and the function of urethra.Simultaneously move pressure-measuring pipe to external orifice of urethra from bladder,, be generally 2ml/ minute,, understand the function of urethra by measuring the pressure condition of urethra different parts by pouring water with certain speed.There is following shortcoming in this urine power instrument.1, patient is a complete operation under undernatured state, and the result often has bigger deviation with patient's practical situation; Will insert pressure-measuring pipe to patient's bladder and internal rectum when 2, checking, genus has wound property inspection meeting to bring bigger misery to patient, and patient's acceptance is poor; 3, checking process complexity needs quite empirical technical staff and operates just and can obtain conclusion relatively accurately, and result not too skilled or that the not high operator of the degree of understanding of urine power has been done is often not credible preferably for operation; 4, the repeatability of Jian Chaing is relatively poor relatively, and the result of twice inspection of contemporaneity sometimes has bigger discrepancy.Owing to making the utilization of urine power, above reason is subjected to very big limit extremely.

Summary of the invention

The present invention is a kind of Non-Invasive urine power instrument, in patient's vein blood vessel, inject a kind of harmless medium during inspection, after the injection, allow patient on instrument, detect the situation of patient's bladder when full, when patient reaches maximum bladder capacity, under the monitoring of instrument urine is being discharged in the urine flow rate instrument, detecting patient in full and the bladder when urinating and the function of urethra.Be a kind of equipment of under naturalness, checking patient's bladder and urethral function.

The technical solution adopted for the present invention to solve the technical problems is: its core technology is the continuously full dynamic ultrasound technology of the multidimensional of medium mediation, promptly by injecting the harmless medium and the diuretic medicine that can increase ultrasonoscopy to venous patient, the effect of diuretic is that the full speed of patient's bladder is increased, reduce the needed time of checking, the effect of medium is that the effect of ultrasonoscopy is strengthened, and makes the result more accurately and reliably.Body surface in the district of patient's bladder and urethra during inspection is settled 3-4 Type B ultrasonic probe, the information that B ultrasonic obtains is gathered continuously and store in microcomputer with the figure capture card, and the finish message that will be stored in microcomputer by self-designed software becomes visual continuous 3D dynamic menu.Realize that patient stores the playback of the urine and the process of urinating.Set up the data model of this urine power of normal person and patient by inspection.When patient checks, need only in a short period of time, in general 30 minutes, just can obtain the 3D current intelligence of this patient when storing urine naturally and urinating.Just can understand patient exactly according to this situation contrast data model normal and patient stores and urinates and the function situation of bladder and urethra when urinating.This instrument compares with traditional instrument, and 1, realized understanding the bladder under patient's naturalness and the situation of urethral function, make the result truer; 2, simple to operate, the operator can grasp this technology in the short period of time, and common operator may obtain satisfied result; 3, realized non-invasive technology, the patient who is checked does not have anything that the infringement of wound is arranged substantially, more acceptant this inspection of patient; 4, the result is more directly perceived, more accurate.

The invention has the beneficial effects as follows that patient is checked under noinvasive and naturalness, and the result of inspection more meets patient's truth, the error of inspection obviously descends; Simultaneously more acceptant this of patient checked relative simply with operation, and common operator can obtain also accurately that the result makes easier the popularizing of urine power inspection; The easier doctor of making of visual result enhancing who is obtained understands, and clinical directive function is strengthened.
