Description

Urine volume detector, measurement system, measurement method, and urine volume notification system

Technical Field

The invention belongs to the technical field of urine volume measurement, and particularly relates to a urine volume detector, a measurement system, a measurement method and a urine volume measurement notification system.

Background

Urination and emptying in healthy people is a natural physiological phenomenon when the bladder is full of urine; however, with age, elderly people with reduced urinary system function, and non-elderly people with impaired autonomic nervous system, or urinary system, are more likely to lose urination impulses and develop urinary incontinence. Women may also develop urinary incontinence after delivery, with reduced urge to urinate and difficulty urinating; for the elderly who need to be cared for, the diapers are worn because of fear of urine leakage, which can damage their self-esteem and reduce their willingness to live; even healthy people, if worried about incontinence, may fear going out, reducing the activity level and thus increasing the likelihood that they will get into a care situation.

To eliminate urinary incontinence, ultrasound-based urine measurement devices have traditionally been used to detect whether urine in the bladder is full and encourage urination before causing urinary incontinence, which measure urine volume by measuring the shape of the bladder using one or more ultrasound transmitters and receivers, rather than examining the shape of the bladder by image as with ultrasound imaging devices; however, since this system does not measure the shape of the bladder by scanning ultrasonic waves, the fullness of urine in the bladder cannot be accurately measured unless ultrasonic waves are accurately irradiated to the bladder. In other words, the ultrasonic urine meter needs to be installed at a position where ultrasonic energy is accurately irradiated to the bladder, but since the position of the bladder varies from person to person, it is necessary to check the position of the bladder by an experienced expert (such as a nurse) and adjust the installation position while checking whether the bladder is accurately measured or not before installing the ultrasonic urine meter; therefore, the current ultrasonic urine measuring instrument is difficult to operate, so that the bladder is difficult to accurately measure, and the urinary incontinence cannot be predicted in advance, and improvement is needed.

Position of the male and female bladder as shown in fig. 1a-1d, the female has a lower position in the pelvis due to the shorter urethra; in addition, the uterus covers the upper part of the bladder, so that even if urine accumulates in the bladder, the bladder does not expand upward due to the presence of the uterus, but rather expands outward and forward, with a somewhat flattened position, in a three-dimensional space, the bladder resembles a somewhat collapsed ball.

The male's prostate is located where the bladder leads to the urethra, pushing up slightly in the pelvis; with age and the onset of prostatitis or prostate cancer, the prostate becomes hypertrophic and the position moves further upward.

Example 1

As shown in fig. 3 or 5a to 5c, there is provided a urine volume detector including an ultrasonic probe 2; the ultrasonic probe 2 includes an outer package 1 and an ultrasonic transceiver 3.

Specifically, the outer package 1 is attached to the lower abdomen of a human body when in use; a plurality of ultrasonic transceivers 3 are arranged in the outer package body 1; the ultrasonic transceiver 3 includes at least three or more; as shown in fig. 3, a plurality of ultrasonic transceivers 3 are distributed in the outer package 1 in a straight line; or as shown in fig. 5a-5c, a plurality of ultrasonic waves are distributed in the outer package body 1 in an array combination manner; the included angle between the normal line of one ultrasonic transceiver 3 positioned in the middle area and the normal line of the irradiation surface of the outer package body 1 is an ultrasonic irradiation angle; the angle range of the ultrasonic irradiation angle is a first angle range or a second angle range so as to adapt to users with different sexes of men and women; the first angle range is 20-25 deg. to fit a male user; the second angular range is 25-30 deg. to fit a female user.

Optionally, the rear of the ultrasonic transceiver 3 is provided with a sound absorbing material, and the front side of the ultrasonic transceiver 3 is also provided with an acoustic matching layer positioned in the irradiation direction; the outer packaging body 1 can wrap the ultrasonic transceiver 3, the sound absorbing material and the acoustic matching layer; the ultrasonic transceiver 3 is made of PZT piezoelectric material, takes the shape of a disc with the diameter of 5 mm and the thickness of 1 mm, the substrate material on the back side can absorb ultrasonic waves, and the structure of the ultrasonic probe 2 can be adjusted according to the prior art; in order to improve the spatial resolution or measurement accuracy of the ultrasonic probe 2, the diameter of the ultrasonic receiver should be increased, but the probe to be worn on the human body must be small, for example, when the diameter of the ultrasonic transceiver 3 is 10 mm, the design of the probe is as follows, the diffusivity of the ultrasonic beam emitted from the ultrasonic transmitter/receiver having a diameter of 10 mm is θ=1.47 degrees, and the beam diffusivity is halved by applying the formula (1).

Alternatively, fig. 4 shows a formula of the non-destructive inspection center of the state university of aihua for calculating the spread range of an ultrasonic beam emitted from an ultrasonic transceiver 3; the spread of the ultrasonic beam is shown in FIG. 4, where v is the propagation velocity of the acoustic wave in the organ 1.5x10 ⁵ Cm, a is the radius of the transmitter/receiver of 0.25 cm, the ultrasonic frequency is 3MHz, and the sound beam propagation range when the sound beam intensity is 1/2 is theta=2.95 degrees;

For a probe for women, five ultrasonic transceiver 3 arrays with a diameter of 5 mm are arranged in a row at a mutual angle of 6.25 degrees, an ultrasonic transceiver 3 array with a beam range of 25 degrees and smaller crosstalk can be formed, and by coating resin, the ultrasonic probe 2 for women is completed by making an angle (i.e., ultrasonic irradiation angle) between the normal direction of the ultrasonic transceiver 3 surface in the center of the array and the normal direction of the irradiation surface of the exterior body 1 25 degrees; for children, unlike adult male and female bladders, the child's bladder is smaller, more elastic, and tends to distend spherically, independent of the presence of the prostate or uterus, and thus female ultrasound probe 2 may be used.

Example 2

As shown in fig. 18, there is provided a urine measurement system, and example 2 differs from example 1 in that: the urine measurement system includes a urine amount detector for transmitting the ultrasonic reflected wave signals of the plurality of ultrasonic transceivers 3 to a screen display device; the screen display device is used for receiving and processing the ultrasonic reflected wave signal sent by the urine volume detector, calculating and correcting the real-time urine volume in the bladder, and displaying the corrected urine volume after the correction is finished; the screen display device may be a personal computer, a cellular phone, or a portable information terminal.

The screen display equipment is internally provided with a calculation module and a correction module; the calculation module is used for calculating the processed ultrasonic reflected wave signal to obtain a first urine accumulation; the correction module is used for correcting the calculated first urine accumulation amount to obtain corrected urine accumulation amount.

Specifically, the correcting the calculated first urine volume includes: sex correction is performed on the first urine volume to obtain a first corrected urine volume;

the first corrected urine volume is:

first corrected urine volume = first urine volume x correction factor (2)

Wherein the correction coefficient is a male correction coefficient or a female correction coefficient or a child correction system so as to adapt to male and female sexes and child users; the male correction coefficient is 0.9-1.0, the female correction coefficient is 1.1-1.2, and the child correction coefficient is 1.

In some other embodiments, the urine volume detector further comprises an acceleration sensor or a gravity direction sensor; the correcting the calculated first urine accumulation includes: performing pose correction on the first urine volume to obtain a second corrected urine volume;

the second corrected urine volume is:

second corrected urine volume = first urine volume x pose coefficient (3)

Wherein, when the first urine accumulation is detected based on the user being in an upright or sitting posture state, the pose coefficient of the user being in an upright or sitting posture state is 1, and the pose coefficient of the user being in a supine posture is 0.9; when the first urine volume is detected based on the user being in the supine posture, the posture coefficient of the user being in the upright or sitting posture is 1.1, and the posture coefficient of the user being in the supine posture is 1.

Specifically, the first urine accumulation amount is:

Wherein the expansion coefficient is male expansion coefficient or female expansion coefficient or children expansion coefficient; the short diameter is the height of the bladder, and the front-back diameter is the depth of the bladder; the male expansion coefficient is 1, the child expansion system is 1, and the female expansion coefficient is 1.1-1.2.

The first accumulated urine volume calculation is based on a conventionally used ultrasonic diagnostic apparatus, and is calculated by measuring the depth and height from the sagittal plane (longitudinal plane) and the horizontal plane (transverse plane) from the sagittal plane upper part, measuring the width from the horizontal plane, and calculating by applying a simplified rotational ellipsoid volume calculation formula; i.e. urine volume = depth x height ≡2, where the long diameter is the transverse fault width of the bladder, the short diameter is the height of the bladder and the anterior-posterior diameter is the depth of the bladder.

Since the long diameter and the front-rear diameter of the male and female are approximately the same when there is no urine accumulation due to the shape of the bladder, and the long diameter of the female is larger than the front-rear diameter as the bladder swells, the long diameter adopted in the present application is the product of the expansion coefficient and the front-rear diameter, and therefore, the calculation of the first urine accumulation amount in the present application is the formula (4).

As shown in fig. 16, there is provided a urine measurement system, and embodiment 5 is different from embodiment 2 in that it includes: a urine volume detector for transmitting the ultrasonic reflected wave signals of the plurality of ultrasonic transceivers 3 to a screen display device;

the screen display device can receive and process the ultrasonic reflected wave signal sent by the urine volume detector and calculate parameters of urine volume measurement, the screen display device sends the calculated parameters to the cloud server, the cloud server further calculates and corrects the parameters of urine volume measurement so as to obtain the real-time urine volume stored in the bladder, and after correction is finished, the corrected urine volume stored in the bladder is sent to the screen display device; and the screen display device is used for receiving and displaying the corrected urine accumulation.

Example 6

There is provided a urine volume measurement method including:

s100: based on the ultrasonic reflected wave signal detected by the urine volume detector, a calculation module calculates the processed ultrasonic reflected wave signal to obtain a first urine volume;

s200: based on the obtained first urine volume, the correction module corrects the calculated first urine volume to obtain a corrected urine volume, and displays the corrected urine volume on the screen display device.

The calculation module and the correction module are located in the cloud server or the screen display device, and can be arranged in a central manager of the medical system as required.

Correcting the calculated first accumulated urine volume includes:

s201: sex correction is carried out on the first urine accumulation, so that the first corrected urine accumulation is obtained; when sex correction is performed, the first corrected urine accumulation amount is:

first corrected urine volume = first urine volume x correction factor (2)

S202: performing pose correction on the first urine volume to obtain a second corrected urine volume; specifically, when measuring urine volume, the pressure state of the internal organs such as the intestinal tract on the bladder varies depending on the standing, sitting or supine state of the subject (caregivers), and when standing and sitting, the internal organ pressure comes from the upper part of the bladder, which limits the longitudinal expansion of the bladder and tends to expand the bladder laterally, and when lying, there is no internal organ pressure, the bladder expands both at the upper part and the side, and for correction, an acceleration sensor or a gravity sensor needs to be installed on the ultrasonic transmitter/receiver probe to distinguish the standing, sitting and supine states of the subject, and to correct the urine volume measurement.

second corrected urine volume = first urine volume x pose coefficient (3)

Wherein, when the first urine accumulation is detected based on the user being in an upright or sitting posture state, the pose coefficient of the user being in an upright or sitting posture state is 1, and the pose coefficient of the user being in a supine posture is 0.9; when the first urine accumulation amount is detected based on the state that the user is in the supine posture, the position coefficient of the user in the upright or sitting posture state is 1.1, and the position coefficient of the user in the supine posture is 1; that is, if the urine measurement in the supine position is used as a reference, the measurement values of the standing and sitting postures are multiplied by 1.1 to make the correction, whereas if the urine measurement in the standing or sitting position is used as a reference, the measurement value in the supine position is multiplied by 0.9 to make the correction.

Step S201 and step S202 may be performed in a cumulative manner without the order of steps, or may be performed by selecting a single mode according to the use requirement, that is, sex correction and posture correction may be performed as required, or may be performed by sex correction alone or posture correction alone.

The first urine volume calculation includes:

s101: establishing a two-dimensional coordinate system based on the irradiation angle of the normal line of each ultrasonic transceiver 3 in the urine volume detector with the human body, as shown in fig. 11, and indicating the normal line of each ultrasonic transceiver 3 in the established two-dimensional coordinate system;

s102: marking the return time of each ultrasonic wave reaching the front wall and the back wall of the bladder on a plurality of normal lines correspondingly based on the established two-dimensional coordinate system and the normal line of each ultrasonic transceiver 3;

s103: simplifying the longitudinal tomographic image of the bladder to be elliptical in shape based on the return time of each of the noted ultrasonic waves to the anterior and posterior bladder walls, as shown in fig. 12;

s104: based on the return time t of each ultrasonic wave to the anterior wall of the bladder ₁ And return time t of the posterior wall of the bladder ₂ And the velocity of the ultrasonic wave, calculate and obtain the distance X between bladder anterior wall and back wall that each said ultrasonic transceiver 3 corresponds to;

Distance between the anterior and posterior bladder walls = ultrasound propagation velocity x (t ₂ -t ₁ )×1/2 (5)

S105: the first urine accumulation amount is calculated based on the simplified obtained oval bladder longitudinal tomographic image and the obtained distance X between the bladder front wall and the bladder rear wall corresponding to each of the ultrasonic transceivers 3.

The first urine volume is:

Wherein the expansion coefficient is male expansion coefficient or female expansion coefficient or children expansion coefficient; the short diameter is the height of the bladder, and the front-back diameter is the depth of the bladder; the location of the minor and anterior-posterior diameters is determined based on a simplified obtained longitudinal tomographic map of the elliptical bladder.

Specifically, when the bladder is full of urine, the ultrasonic reflected wave path of the ultrasonic transceiver 3 will take the shape shown in fig. 6 a; the curve in FIG. 6b is the extrapolated peak of the reflected pulse wave, t ₁ The time corresponds to the peak value of the reflected wave of the bladder front wall, t ₂ The time corresponds to the peak value of the reflected wave of the back wall of the bladder; when the bladder is filled with urine, the reflection and scattering of ultrasonic waves are smaller and the ultrasonic waves are easier to penetrate, so that a region with lower reflection intensity is formed, t ₁ And t ₂ The corresponding peaks are located on either side, and the distance between the bladder walls is determined by the ultrasound velocity (v=1500 m/s) and the propagation time difference (t ₂ -t ₁ ) The corresponding equation (5) is found, for example, if t ₁ ＝4x10 ^-5 Second, t ₂ ＝16x10 ^-5 Second, then distance x=7.5x10 ^-2 Meter=7.5 cm.

When 3MHz ultrasonic waves are emitted at 3 wavelengths, the ultrasonic wave transmission time of one element is 3.3.times.10 ⁶ ＝10 ⁶ The ultrasonic measurement time of one element, i.e., the time when the ultrasonic wave emitted from the ultrasonic transceiver 3 is reflected back, can be calculated as 1 (m)/1500 (m/s) =6.7x10 ^-4 (s) if the body width of the measured human body is 0.5m and the round trip is 1m, the measurement time is about 10 ^-3 Within S, a transmitting/receiving time of one element is 10 ^-6 (s) ultrasonic waves are emitted from one element, followed by 10 ^-3 The internal reflected wave is received, amplified, analog signal is converted into digital signal and stored in memory, and 5 transmitting/receiving times are 10 ^-3 X 5, also requiring the addition of 5 membersThe switching time of the pieces, for example, the time required for one transmission/reception is about 1 millisecond, and the continuous measurement time interval of the adjacent ultrasonic transceivers 3 is longer than this time interval, and the operation of all the ultrasonic transceivers 3 of the ultrasonic probe 2 is intermittently repeated.

Processing the waveform of each ultrasonic transceiver 3 includes: step E1: as shown in fig. 7, after receiving the analog signal, amplifying and changing the digital signal; step E2: as shown in fig. 8, the ultrasonic wave is smoothed, and the signal is an ac signal, which can be rectified; step E3: as shown in FIG. 9, a threshold is set to remove noise for a time t ₁ And t ₂ Is the intersection of the smoothed data with a threshold value, where t ₁ Is the time corresponding to the anterior wall of the bladder, t ₂ Is the time corresponding to the posterior wall of the bladder.

The ultrasonic wave transmitted into the human body gradually weakens in intensity after repeated scattering and reflection, and the ultrasonic wave is reflected and scattered by tissues around the bladder, but the ultrasonic wave entering the bladder is not attenuated, but is transmitted straight ahead and is mainly reflected by the back wall of the bladder, because urine in the bladder is hardly reflected and absorbed.

As shown in fig. 10a to 10e, when the ultrasonic probe 2 includes five ultrasonic transceivers 3, five pairs t are obtained ₁ And t ₂ The data, ultrasonic transmitter and human body are longitudinally arranged.

Alternatively, as shown in fig. 13-14, two ways of urine volume measurement are presented.

Urine volume display can be classified into 5 grades, and can be specifically expressed as characters or increase/decrease of urine volume; if none of the ultrasonic reflected waves corresponding to the 5 ultrasonic transceivers 3 appear t ₂ At that moment, the urine volume is displayed as extremely low; only one ultrasonic reflected wave t corresponding to the ultrasonic transceiver 3 occurs ₂ At that moment, the urine volume is displayed as low; if there are two ultrasonic wave transceivers 3 corresponding to the ultrasonic reflected wave t ₂ At the moment, the urine volume is displayed as a medium-low level; if there are three ultrasonic reflected waves corresponding to the ultrasonic transceivers 3, t occurs ₂ At that moment, the urine volume is displayed as a medium level; if there are four ultrasonic transceivers 3 corresponding to the ultrasonic counterT is generated by the wave ₂ At the moment, the urine volume is displayed as high level, and a urination instruction is sent out; if there are five ultrasonic wave transceivers 3 corresponding to the ultrasonic reflected wave t ₂ At that moment, the urine volume is displayed as dangerous and an emergency urination indication is given.

Example 7

A urine volume measurement notification system is provided, and embodiment 7 differs from embodiment 2 in that; comprising the following steps: a urine volume detector for transmitting the ultrasonic reflected wave signals of the plurality of ultrasonic transceivers 3 to a screen display device; the screen display device is used for receiving and processing the ultrasonic reflected wave signal sent by the urine volume detector, calculating and correcting the real-time urine volume in the bladder, displaying the corrected urine volume after the correction is finished, and sending a urination instruction after the corrected urine volume reaches a urination threshold value; the screen display device comprises an alarm module, and when the corrected urine accumulation amount is larger than a urination threshold value, the alarm module gives an alarm on the screen display device and/or a notification device equipped on a sickbed.

In some other embodiments, the screen display device is connected to the global positioning system for displaying the position of the public toilet, and the connection mode of the screen display device and the global positioning system can refer to the prior art, so that a user knows the position of the public toilet when using the public toilet, and the worry of urinary incontinence is eliminated.

Specifically, a notification button may be provided on the urine measurement device to notify, and in addition, a call bell button provided on the hospital bed in the facility may be used to notify information.

There are large individual differences in the volume of the bladder and the urine volume at the urine level and the urine volume at the incontinence level, and the relationship between the urine volume measurement and the urination alarm indicating level needs to be optimally adjusted for each individual, so it is preferable to schedule a training time to train to obtain a more accurate urination threshold value.

Specifically, during training, people who can express urine will be required to input the time they produce urine, which will be recorded with the measured urine volume and learned by artificial intelligence in the server to obtain the time to notify the urination alarm before they feel urine; specifically, a urination notification button may be provided in the urine volume detector, and when a user feels that he or she needs urination, the button is immediately pressed to cause the urine volume detection device to obtain notification.

Because the rate of increase of urine volume in the bladder varies with factors such as daily physical activity of the individual, drink diet, season, temperature, etc., artificial intelligence will learn these changes and issue a urination alarm notification based on the change in urine volume most appropriate for the individual, if the individual is able to urinate by himself, the system will notify them when to urinate by himself, if the patient needs care, the time will be entered after the caretaker assists the patient in urinating.

For those who have urinary incontinence before feeling conscious, it is necessary to measure the change in urine volume and the time of urinary incontinence during training. During measurement of urine volume, when the volume decreases, the artificial intelligence will know the time of incontinence and issue a urination alarm before incontinence to assist the caregiver in urination. Artificial intelligence in the server will learn this data and correlate it with optimal urination warning times and urination assistance.

The different specifications of men and women can improve the measurement difficulty of the urine volume of men and women caused by the organ structures of men and women, such as the prostate of men and the uterus of women, and the specifications of men and women can be further compensated by using men with large sizes or women with small sizes.

Thus, an ultrasound-based urine measurement system helps to reduce care costs and care effort by optimizing individual urination and reducing individual diaper usage, and also reduces post-urination disposal by caregivers by reducing individual diaper usage to increase daily comfort.
