Described signal analysis and processing module 9 realizes by the DSP signal processing chip, is used to carry out filtering and envelope extraction and handles, and removes the noise in the signal.After signal analysis and processing module 9 receives the digital signal that A/D data acquisition circuit 8 transmits, signal is carried out filtering and envelope extraction, and analytical calculation characterizes the signal of bladder front and rear wall positional information, calculate bladder front and rear wall distance, bladder front and rear wall distance (defined threshold) compares during with the filling of bladder of prior preservation, if the value that calculates meets or exceeds the value of preservation, can assert that then bladder has reached full.Described A/D data acquisition circuit 8 is realized by the A/D modulus conversion chip, is used for analogue signal is converted into digital signal.

Measure bladder front and rear wall distance by A-mode ultrasonic probe 1, A-mode ultrasonic probe 1 penetrates human body and bladder by the emission ultrasound wave, ultrasound wave can reflect when arriving ultrasonic front and rear wall, because the degrees of expansion difference of bladder, the time that the reflected signal of sign bladder front and rear wall occurs in the ultrasound echo signal is also different, the time difference of the reflected signal of bladder front and rear wall be multiply by the front and rear wall distance that hyperacoustic velocity of sound can obtain bladder, when bladder front and rear wall distance reaches defined threshold (being generally about 10cm), then can regard as filling of bladder.Described A-mode ultrasonic 1 angle of popping one's head in is-5 °～-15 ° for normal patient, is-15 °～-25 ° for bladder platypelloid type patient, and the patient of comparatively swelling for bladder is-5 °～+ 5 °.

A-mode ultrasonic transmitting and receiving module 2 is connected with A-mode ultrasonic probe 1, A-mode ultrasonic transmitting and receiving module 2 transmitted pulse signals, excitation A-mode ultrasonic probe 1 emission ultrasound wave, ultrasound wave is received and amplification by A-mode ultrasonic transmitting and receiving module 2 after A-mode ultrasonic probe 1 is converted into the signal of telecommunication through the echo-signal after the tissue emission, and then convert digital signal to and analyze by ultrasonic signal processing module 3 collection, judge whether bladder front and rear wall range information reaches defined threshold in the digital signal, if bladder front and rear wall range information reaches threshold value, thenalarm module 4 is reported to the police, and reminds nursing staff or patient.

Described A-mode ultrasonic probe 1 is fixed on patient's lower abdomen median sagittal plane epipubis co-location, A-mode ultrasonic probe 1 emission ultrasound wave under the excitation of the pulse signal that pulse signal generator 5 produces, A-mode ultrasonic probe 1 will be collected echo-signal and be converted into and pass signal filtering amplifying circuit 7 back behind the electric impulse signal and amplify.Ultrasound emission receives control module 6 control wave generators 5 and produces pulse signal, and control signal filter amplification circuit 7 is carried out filtering and amplification with the signal that receives; Electric impulse signal after amplifying is sent to A/D Acquisition Circuit 8 by signal filtering amplifying circuit 7 again, be converted into digital signal by A/D data acquisition circuit 8, again digital signal is passed to signal analysis and processing module 9 and carried out filtering and envelope extraction processing, judge whether bladder front and rear wall range information reaches setting threshold, if bladder front and rear wall range information reaches threshold value, then report to the police by thealarm module 4 that links to each other with signal analysis and processing module 9.

When patient's bladder is full, when partly filling and filling fully, the ultrasonic signal that A-mode ultrasonic transmitting and receiving module 2 receives from Fig. 3-A, 3-B and 3-C as can be seen: during filling of bladder, the bladder front and rear wall is apart from increase, and the signal location that characterizes bladder front and rear wall distance in the ultrasonic echo changes.Described ultrasonic signal processing module 3 can also be carried out Filtering Processing except carrying out the threshold decision, to remove the noise in the echo-signal.

What the present invention proposed is a kind of based on the urinate alarming method by monitoring of bladder front and rear wall apart from detection, as shown in Figure 4, specifically comprises following step:

Step 1: will be fixed on patient's lower abdomen median sagittal plane epipubis co-location apart from the monitoring alarm of urinating that detects based on the bladder front and rear wall, and on median sagittal plane, be the angle of adjusting A-mode ultrasonic probe 1 in 20 °～-60 ° the scope with sagittal axis according to different patients' bladder type.Normal patient is-5 °～-15 °, bladder platypelloid type patient-15 °～-25 °, and the patient that bladder comparatively swells is-5 °～+ 5 °;

Step 2: start the A-mode ultrasonic transmitting and receiving module;

Step 3: by pulse signal generator 5, excitation A-mode ultrasonic probe 1 is to the abdominal part pubic symphysis position of measurand emission A-mode ultrasonic signal;

Step 4: A-mode ultrasonic probe 1 receives the echo-signal that tested position produces, and is converted into electric impulse signal;

Step 5: A-mode ultrasonic probe 1 is sent to signal filtering amplifying circuit 7 with electric impulse signal, electric impulse signal is after signal filtering amplifying circuit 7 carries out filtering, processing and amplifying, send to A/D data acquisition circuit 8, by A/D data acquisition circuit 8 electric impulse signal after the filter amplifying processing is converted into digital signal by analogue signal, and this digital signal is sent to the signal analysis and processing module;

Step 6: signal analysis and processing module 9 is carried out analytical calculation with the digital signal that receives, compare with the bladder front and rear wall range information of storage, if the bladder front and rear wall that calculates in the signal that receives distance meets or exceeds the distance of storage, then bladder has reached full, and then alarm module is reported to the police; Otherwise it is full that bladder does not also reach, and returns step 3.

Owing to use patient's individual variation, during different patient's filling of bladder, the expansion of the bladder direction is different.Therefore; in the present invention by the adjustable A-mode ultrasonic probe 1 of use angle; be convenient to select or adjust the angle of ultrasonic 1 probe of A-mode ultrasonic according to the individual instances of user; shown in Fig. 5-A; A-mode ultrasonic 1 angle of popping one's head in was about-15 ° when normal patient was used; the penetrable bladder front and rear wall of ultrasound wave this moment, the front and rear wall distance is at the defined threshold place during filling of bladder.Shown in Fig. 5-B, comparatively flat during as if patient's filling of bladder, then A-mode ultrasonic is popped one's head in 1 angle need to the adjustment of negative angle direction.Shown in Fig. 5-C, comparatively swell during as if patient's filling of bladder, then A-mode ultrasonic is popped one's head in 1 angle need to the adjustment of positive-angle direction.
