Description

Urodynamic measurement apparatus

The present invention relates to a device for urethral dynamics test.

Urination dysfunction is a symptom observed in patients with various urination diseases such as urinary incontinence, prostate hyperplasia, prostate cancer, cystitis, and bladder cancer. Diagnosis of urinary dysfunction may include selective medical examination, physical examination, radiographic examination, endoscopy, and urinadynamics.

In particular, urodynamic studies provide important information in diagnosing various urination dysfunctions, namely, difficulty in urination, urinary incontinence, neurogenic bladder, and determining the treatment policy. This test is important because it can help you diagnose urination disorders more accurately. In particular, the physiological function and condition of the lower urinary tract, which are unknown by questionnaires, physical examinations, radiographic examinations, and endoscopy, can be objectively grasped.

Urinary kinetic tests consist of three tests: urinary flow test, bladder pressure measurement, and sphincter function test.

Urinary tract examination is a test to determine whether there is detrusor muscle contraction or bladder outlet obstruction in patients who complain of urination difficulty. Bladder pressure measurement tests bladder function by recording pressure change during filling and urination. The sphincter function test is performed through electromyography, urethral pressure measurement, or urinary leak pressure measurement to determine the function of the sphincter. In recent years, urinalysis and bladder pressure measurement are simultaneously performed, and electromyography and imaging may be selectively performed.

Bladder pressure sensor 20 is connected to the bladder catheter 22 is inserted into the bladder through the urethra, the abdominal pressure sensor 21 is connected to the abdominal pressure catheter 23 is inserted into the anus, respectively, to detect the pressure of the bladder and abdomen, respectively Done.

In order to accurately measure bladder pressure, the end of the bladder catheter 22 inserted into the bladder and the end of the abdominal pressure catheter 23 should be positioned at the same height as the bladder pressure sensor 20 and the abdominal pressure sensor 21. Conventionally, the examiner manually touches the abdomen of the patient to find the pubic area by experience and manually adjusts the position so that the bladder pressure sensor 20 and the abdominal pressure sensor 21 are positioned at the upper end of the pubic area, but according to the present invention, When the pubic upper end detection unit 40 and the sensor include the moving means 30, the position of the bladder pressure sensor 20 and the abdominal pressure sensor 21 can be automatically adjusted.

Referring to FIG. 1, the sensor moving means 30 includes a sensor moving member 31 having a bladder pressure sensor 20 and a abdominal pressure sensor 21 coupled thereto, and a sensor guide body having a long hole through which the sensor moving member 31 is moved. 32, and sensor lifting means (not shown) for lifting and lowering the sensor moving member 31. The sensor lifting means receives the signal from the upper pulp upper detection unit 40 described later and positions the bladder pressure sensor 20 and the abdominal pressure sensor 21 at the same height as the upper pubic bone detected.

On the other hand, the pubic upper end detection unit 40 includes an ultrasonic probe 41, a probe moving means 42, and the ultrasonic control unit 44.

Referring to FIG. 1, the probe moving means 42 includes a probe moving member 42a having an ultrasonic probe 41 coupled thereto, a probe guide body 42b having a long hole through which the probe moving member 42a is moved, and a probe. It may be configured to include a probe lifting means (not shown) for lifting the moving member (42a).

The ultrasonic controller 44 controls the ultrasonic probe 41 and the probe moving means 42 to detect the upper boundary of the pubic bone, and detects the upper boundary of the pubic bone based on a signal input from the ultrasonic probe 41. .

3 is a diagram schematically illustrating an operation of detecting the upper end of the pubic bone in the upper pubic upper detecting unit 40 according to the first embodiment of the present invention based on an ultrasonic signal, and FIG. 4 is a flowchart of the same.

Referring to FIG. 3, the bladder is located immediately after the pubic region, and the heights of the ends of the bladder catheter 22 and the abdominal catheter 23 are located at the upper surface of the pubic bone, that is, at the interface between the bladder and the pubic region. The upper pubic upper detecting part 40 is configured to detect the upper end of the pubic bone, that is, the boundary between the pubic bone and the bladder.

3 and 4, the ultrasonic probe 41 is initially located at the bottom of the probe guide body 42b (S10). The ultrasonic controller 44 applies a control signal to the probe lifting means to move the ultrasonic probe 41 from the bottom to the top (S11). As a result, the ultrasonic controller 44 obtains an ultrasonic signal according to the movement (S12).

In the ultrasound signal of FIG. 3, it can be seen that lines are formed in the right region at the interface between the pubic bone and the bladder. That is, the area where the bladder begins to scan past the pubic area. Therefore, the ultrasonic control unit 44 according to the present invention detects the position where the new line is generated in the right region as the upper end of the pubis (S13). Thereafter, the bladder pressure sensor 20 and the abdominal pressure sensor 21 are positioned at the same height as the upper end of the detected pubic bone to detect the bladder pressure and the abdominal pressure (S14 and S15).

As described above, the ultrasound controller 44 analyzes the image acquired from the ultrasound probe 41 to detect the upper surface of the pubis (S30) and move the ultrasound probe 41 to the detected position (S31). .

The ultrasonic controller 44 controls the probe moving member 42a to direct the ultrasonic probe 41 downward at an angle of 30 degrees (S32). Then, the probe lifting means is controlled to move the ultrasonic probe 41 upward from the upper surface of the pubic bone (S33), thereby obtaining an ultrasonic signal according to the movement (S34).

8A and 8B schematically show the position of the ultrasonic probe 41 and the ultrasonic signal obtained therefrom. 8A and 8B, the boundary between the lower pubic bone and the bladder, and the boundary between the bladder and the abdomen (intestine) may be determined through an ultrasonic signal.

The ultrasound controller 44 detects a point where the bladder region is closest to the ultrasound probe 41 in the acquired ultrasound signal (S35). In FIG. 8B, a point denoted by a dotted line circle is used. The ultrasonic controller 44 controls the probe lifting means to move the ultrasonic probe 41 to the corresponding position (S36).

The ultrasound controller 44 controls the probe scanning means to scan the ultrasound probe 41 up, down, left, and right (S37) to obtain an ultrasound signal and measure the residual urine volume of the bladder based on the cross-sectional images (S38).

As such, according to the present invention, it is possible to measure the urination muscle strength and the residual urine volume of the bladder without a tester, thereby reducing the burden on the patient and being economical and efficient.

It is possible to interwork with the computer 1 wirelessly. The wireless communication module may be a communication module such as Bluetooth, WLAN, home RF, or IrDA used for short-range communication.

The computer 1 stores and executes a program for analyzing the test results, and analyzes and displays the measured data received from the urine dynamics tester through the wireless screen. Accordingly, the inspector can know whether the examination is progressing and the test result through the computer 1 outside the hospital room. In addition, a user interface, such as a keyboard and a mouse, is connected to the computer 1 so that the examiner can control the operation and state of the yaw dynamics test apparatus.

As described above, according to the urethradynamic test apparatus according to the present invention, since the test can be performed without an examiner, the test can be performed alone in a bathroom or a private room, thereby reducing the burden on the body exposure of the patient. In addition, by providing a small size for each patient to wear the measurement module, and by transmitting the data measured through the wireless, it is possible to proceed with the test simply and conveniently.
