Description

Technical Field

[0001] This application relates to the technical field of urine volume monitoring, and particularly to a portable urine volume monitoring device. Background Art

[0002] Urinary incontinence is a pathological condition in which the ability to control urination is weakened or lost due to damage to the bladder sphincter or neurological dysfunction, causing urine to be excreted uncontrollably. It can be seen in patients of any age and gender. Especially for some elderly and special patients who are bedridden for a long time and have lost their communication or perception abilities, they may not be able to perceive or inform people around them in time when urinary incontinence occurs, resulting in urine soaking the skin and causing complications such as skin infections, rashes, pressure sores, and recurrent urinary tract infections, seriously affecting personal physical and mental health and being disadvantageous to their normal life.

[0003] Ultrasonic examination is the main imaging function for clinically monitoring bladder urination function. By measuring the left-right diameter, anterior-posterior diameter, and superior-inferior diameter of the bladder, the bladder volume can be calculated, and by comparing the difference in bladder volume before and after urination, the bladder urination function can be reflected. However, the current ultrasonic devices are generally large in size, and generally need to be examined by professional personnel for urinary incontinence patients in professional medical places. At the same time, due to the requirements of the size of ultrasonic devices, monitoring environment, and operation professionalism, continuous monitoring cannot be provided for more groups with urinary incontinence symptoms. Summary of the Invention

[0004] The purpose of this application is to provide a portable urine volume monitoring device with a light and convenient structure for carrying, which can provide continuous monitoring of urine volume for urinary incontinence patients.

[0005] To achieve the above purpose, this application provides the following solutions:

[0006] This application provides a portable urine volume monitoring device, which is fixed to the abdomen of the user. The portable urine volume monitoring device includes: a housing, a movable carrier plate, an ultrasonic detection unit, a driving unit, a coupling agent release unit, a pressure-infrared dual-mode feedback unit, and a processor; the housing is a hexahedron structure without a bottom, including a top plate, side walls, and support columns; a retaining piece is provided at the bottom of the support columns; the movable carrier plate is provided with a first through hole and a second through hole;

[0007] The movable carrier plate is arranged at the bottom of the housing; the four corners of the movable carrier plate are inner arc chamfers, and each inner arc chamfer is embedded with a movable ball; the movable carrier plate is used to cooperate with the movable balls to move up and down between the top plate and the retaining piece along the support columns;

[0008] The ultrasonic detection unit is fixed at the first through hole; the ultrasonic detection unit is used to obtain the cross-sectional image of the user's bladder; the cross-sectional image of the bladder includes a transverse cross-sectional image of the bladder and a longitudinal cross-sectional image of the bladder;

[0009] The driving unit is fixed on the upper surface of the movable carrier plate and meshes with the ultrasonic detection unit through a gear; the driving unit is used to adjust the rotation angle of the ultrasonic detection unit;

[0010] The coupling agent release unit is fixed at the second through hole; the coupling agent release unit is used to release the coupling agent at a set frequency when the ultrasonic detection unit is working;

[0011] The pressure infrared dual-mode feedback unit is fixed between the top plate and the movable carrier plate; the pressure infrared dual-mode feedback unit is used to measure the longitudinal pressure between the user's abdominal skin and the movable carrier plate, and the body surface height during the user's bladder filling process;

[0012] The processor is respectively connected to the ultrasonic detection unit, the driving unit, the coupling agent release unit and the pressure infrared dual-mode feedback unit; the processor is used to determine the urine volume in the user's bladder according to the transverse cross-sectional image of the bladder and the longitudinal cross-sectional image of the bladder; control the driving unit to adjust the rotation angle of the ultrasonic detection unit; control the release frequency of the coupling agent; determine the bladder filling state of the user according to the longitudinal pressure or the body surface height.

[0013] According to the specific embodiments provided by the present application, the following technical effects are disclosed in the present application:

[0014] The present application makes full use of the movable carrier plate to fix multiple functional units, and at the same time, the multiple functional units are centrally arranged inside the housing, effectively reducing the volume of the device and facilitating carrying. At the same time, in the actual use process, only by fixing the device on the user's abdomen can the continuous monitoring of urine volume be realized. This is because the movable carrier plate designed in the present application can move up and down between the top plate and the baffle of the housing in cooperation with the movable ball. During the up and down movement of the movable carrier plate, the pressure infrared dual-mode feedback unit can measure the longitudinal pressure between the user's abdominal skin and the movable carrier plate in real time, and the body surface height during the user's bladder filling process. The bladder filling situation of the user can be effectively reflected through the changes of the above two quantities, and then it can be determined whether there is urine excretion. Because the device is fixed, the measurement work of the pressure infrared dual-mode feedback unit is also continuous, so the continuous monitoring of urine volume can be realized. In addition, since the ultrasonic detection unit can change the angle under the control of the driving unit, it is possible to effectively obtain the transverse and longitudinal cross-sectional diagrams of the bladder without the operation of professionals, and then determine the urine volume in the bladder to achieve continuous monitoring.

Detailed implementation manners

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0026] When using a traditional ultrasonic device to check the urine volume in the bladder, there are certain requirements for the inspection site and inspectors, and it cannot be used as a tool for continuously monitoring the urination situation; the traditional ultrasonic device cannot effectively fix the probe, and the probe may not be aligned with the bladder during use, resulting in the inability to obtain continuous and stable image data; in the traditional device solution for monitoring urination using ultrasound, the method of ultrasonic coupling is not mentioned, which is not conducive to long-term ultrasonic detection and may also cause local skin discomfort; in the continuous monitoring of the traditional ultrasonic device, there may be a situation where the image acquisition fails due to the displacement of the device.

[0027] The purpose of the present application is to provide a portable urine volume monitoring device, which is light in structure and convenient to carry, and can provide continuous monitoring of the urine volume for urinary incontinence patients.

[0028] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] In an exemplary embodiment, as Figure 1 shown, a portable urine volume monitoring device is provided, including: a housing 1, a movable carrier plate 2, an ultrasonic detection unit 3, a driving unit 4, a coupling agent release unit 5, a pressure infrared dual-mode feedback unit 6, and a processor (not shown in the figure). When the portable urine volume monitoring device is in use, it needs to be fixed on the abdomen of the user. The fixing method can be to stick the portable urine volume monitoring device on the abdomen of the user with 3M skin-friendly film, or to wear the portable urine volume monitoring device on the abdomen of the user with an elastic band.

[0030] As Figure 2 and Figure 3As shown, the housing 1 is a hexahedron structure without a bottom (in this embodiment, the housing is a cuboid structure without a bottom surface), including a top plate 11, side walls 12 (four) and support columns 13 (four); a retaining piece 14 (triangular in this embodiment) is provided at the bottom of the support column 13; a first through hole 21 (circular in this embodiment) and a second through hole 22 (in the shape of a "convex" character in this embodiment) are formed in the movable bearing plate 2 (the length and width of which are the same as those of the top plate 11, and the thickness is greater than 1 mm); the movable bearing plate 2 is arranged at the bottom of the housing 1; the four corners of the movable bearing plate 2 are chamfered with inner arcs, and each inner arc chamfer is embedded with a movable ball; the movable bearing plate 2 is used to cooperate with the movable ball to move up and down between the top plate 11 and the retaining piece 14 along the support column 13. The function of the baffle 14 is to limit the movable bearing plate 2 and at the same time ensure that the movable bearing plate 2 does not fall off from the bottom of the housing 1.

[0031] Specifically, the ultrasonic detection unit 3 is fixed at the first through hole 21, and the ultrasonic detection unit 3 is used to obtain cross-sectional images of the user's bladder (including transverse cross-sectional images and longitudinal cross-sectional images of the bladder). The ultrasonic detection unit 3 generates high-frequency vibrations under the inverse piezoelectric effect to form ultrasonic waves. The ultrasonic waves can be transmitted in the human body and generate echo signals with different intensities according to the density differences of human tissues. After the ultrasonic wave receiver receives the echo, it converts it into an electrical signal and transmits it to the processor. The processor processes the electrical signal to generate cross-sectional images of the bladder.

[0032] The driving unit 4 is fixed on the upper surface of the movable bearing plate 2 and meshes with the ultrasonic detection unit 3 through gears; the driving unit 4 is used to adjust the rotation angle of the ultrasonic detection unit 3.

[0033] The coupling agent release unit 5 is fixed at the second through hole 22; the coupling agent release unit 5 is used to release the coupling agent at a set frequency when the ultrasonic detection unit 3 is working (in this embodiment, silicone oil is selected as the coupling agent, mainly considering that conventional coupling agents are rich in moisture and may cause skin diseases after long-term soaking of the skin. While silicone oil has the function of ultrasonic sound conduction, it has little irritation to the skin and can play a role in moisturizing the skin).

[0034] The pressure-infrared dual-mode feedback unit 6 is fixed between the top plate 11 and the movable bearing plate 2; the pressure-infrared dual-mode feedback unit 6 is used to measure the longitudinal pressure between the user's abdominal skin and the movable bearing plate 2, and the body surface height during the process of the user's bladder filling.

[0035] The processor is respectively connected to the ultrasonic detection unit 3, the driving unit 4, the coupling agent release unit 5 and the pressure-infrared dual-mode feedback unit 6; the processor is used to determine the urine volume in the user's bladder according to the transverse cross-sectional image and the longitudinal cross-sectional image of the bladder; control the driving unit 4 to adjust the rotation angle of the ultrasonic detection unit 3; control the release frequency of the coupling agent; determine the bladder filling state of the user according to the longitudinal pressure or the body surface height.

[0036] Further, as Figure 4 shown, the ultrasonic detection unit 3 includes: a limit plate 31 (circular in this embodiment, with a radius greater than that of the first through hole 21), an ultrasonic probe 32 (a convex array probe in this embodiment), a first gear 33, and a wire harness 34; a probe hole is formed on the limit plate 31 (the shape of which is the same as the cross-sectional shape of the ultrasonic probe 32, but its cross-sectional area is smaller than that of the ultrasonic probe 32 to facilitate clamping the ultrasonic probe 32); a central through hole is formed on the first gear 33.

[0037] The limit plate 31 is arranged on the upper surface of the first through hole 21 (the upper surface of the first through hole 21 corresponds to the upper surface of the movable carrier plate 2), the ultrasonic probe 32 is arranged on the lower surface of the first through hole 21 (the lower surface of the first through hole 21 corresponds to the lower surface of the movable carrier plate 2), and the limit plate 31 and the ultrasonic probe 32 are fixedly connected. The fixing method can be to screw the limit plate 31 and the ultrasonic probe 32 together on both sides of the probe hole with screws.

[0038] The first gear 33 is fixed to the limit plate 31. The fixing method can be to screw the first gear 33 and the limit plate 31 together with screws, or two tenons can be arranged on the upper surface of the limit plate 31 and two tenon grooves can be arranged on the first gear 33, and the first gear 33 and the limit plate 31 are fixed by using the tenons and the tenon grooves; one end of the wire harness 34 is connected to the interface of the ultrasonic probe 32, and the other end of the wire harness 34 sequentially passes through the first through hole 21, the probe hole, and the central through hole and is connected to the processor. The first gear 33 can drive the limit plate 31 and the ultrasonic probe 32 to rotate together while rotating.

[0039] Further, as Figure 5 shown, the driving unit 4 includes: a motor bracket 41 (inverted "L" shape in this embodiment), a driving motor 42, a second gear 43 (with the same size and shape as the first gear 33), and a shaft seat 44.

[0040] One end of the motor bracket 41 fixes the driving motor 42, and the other end of the motor bracket 41 and the shaft seat 44 are both fixed on the upper surface of the movable carrier plate 2; the rotating shaft of the driving motor 42 passes through the second gear 43 and is placed in the groove of the shaft seat 44; the second gear 43 and the first gear 33 are meshed with each other; the specific fixing position of the shaft seat 44 is jointly determined by the first gear 33 and the second gear 43. First, it is necessary to ensure that the position of the second gear 43 forms a meshing relationship with the position of the first gear 33, then the position of the shaft seat 44 is determined according to the central position of the second gear 43, and finally the motor bracket 41 is fixed on one side of the shaft seat 44.

[0041] Further, as Figure 6As shown, the coupling agent release unit 5 includes: a coupling agent storage box 51 (a cuboid in this embodiment) and a coupling agent release channel 52 (a flat pipe in this embodiment); a pusher 511, a pressing plate 512 (having the same shape as the top surface of the coupling agent storage box 51 but slightly smaller in size), a first hydraulic column 513, and a first hydraulic rod 514 are arranged in the coupling agent storage box 51.

[0042] The coupling agent release channel 52 is connected to the side wall of the coupling agent storage box 51, that is, a flat opening is formed at the junction of the side wall and the bottom surface, and then the flat opening is connected to the coupling agent release channel 52 as a whole. After the coupling agent release channel 52 is connected to the coupling agent storage box 51, a "convex" shape is formed, which is exactly the same as the shape of the second through hole 22, facilitating the fixation of the entire coupling agent release unit 5 at the second through hole 22. To facilitate the fixation and replacement of the entire coupling agent release unit 5, a tenon groove (one is provided on each of the left and right sides) is opened at the bottom of the coupling agent storage box 51, and movable tenons (two are provided corresponding to the left and right tenon grooves) are arranged in the second through hole 22. The movable tenons are used to cooperate with the tenon grooves to fix the coupling agent release channel 52 and the coupling agent storage box 51 at the second through hole 22, and a dial is arranged on the lower surface of the movable support plate 2. The dial is fixedly connected to the movable tenon, and the dial is used to control the release and retraction of the movable tenon (when the dial is on the left side, the movable tenon retracts, and when the dial is on the right side, the movable tenon releases). In addition, the length of the coupling agent release channel 52 determines its distance from the ultrasonic probe 32. Generally, it is best to ensure that the outlet of the coupling agent release channel 52 is close to the ultrasonic probe 32, so that the coupling agent is released at the skin position corresponding to the ultrasonic probe 32, effectively playing a lubricating role.

[0043] The pusher 511 is connected to the processor. One end of the pusher 511 is fixed to the top of the coupling agent storage box 51, and the other end of the pusher 511 is fixedly connected to one end of the first hydraulic column 513; one end of the first hydraulic rod 514 is fixed to the pressing plate 512, and the other end of the first hydraulic rod 514 is connected to the other end of the first hydraulic column 513; the space formed by the pressing plate 512 and the side wall and bottom of the coupling agent storage box 51 is used to store the coupling agent; the pusher 511 is used to drive the pressing plate 512 to press down to release the coupling agent in the coupling agent storage box 51. Since the pusher 511 is connected to the processor, the processor can control the pressing force and frequency of the pressing plate 512, and thus control the release frequency of the coupling agent.

[0044] Further, as Figure 7As shown in the figure, the pressure and infrared dual-mode feedback unit 6 includes: a pressure sensor 61, a second hydraulic column 62, a second hydraulic rod 63, and an infrared distance sensor 64. In order to achieve the smooth lifting of the movable bearing plate 2, two pressure and infrared dual-mode feedback units 6 are provided between the movable bearing plate 2 and the top plate 11. The two pressure and infrared dual-mode feedback units 6 are evenly distributed on both sides of the internal space of the housing 1, that is, one pressure and infrared dual-mode feedback unit 6 is provided on one side of the top plate 11 and the movable bearing plate 2, and another pressure and infrared dual-mode feedback unit 6 is provided on the other side of the top plate 11 and the movable bearing plate 2 to achieve balance.

[0045] The upper surface of the pressure sensor 61 is fixed on the top plate 11, and the lower surface of the pressure sensor 61 is fixed to one end of the second hydraulic column 62; the other end of the second hydraulic column 62 is connected to one end of the second hydraulic rod 63; the other end of the second hydraulic rod 63 is fixed on the movable bearing plate 2; the infrared distance sensor 64 is provided at one end of the second hydraulic rod 63 connected to the second hydraulic column 62; the pressure sensor 61 is used to measure the longitudinal pressure between the abdominal skin of the user and the movable bearing plate 2. It mainly measures the change in the longitudinal pressure between the abdominal skin and the movable bearing plate 2 through the movement of the second hydraulic rod 63. When the bladder is full, the abdominal internal pressure increases, the movable bearing plate 2 is pressed upward, and the second hydraulic rod 63 contracts. When the bladder is emptied, the abdominal internal pressure decreases, and the second hydraulic rod 63 returns downward; the infrared distance sensor 64 is used to determine the body surface height during the bladder filling process of the user by measuring the height of the second hydraulic column 62.

[0046] In addition, the above portable urine volume monitoring device further includes: a power supply unit (not shown in the figure), a display unit (not shown in the figure), and a wireless transmission unit (not shown in the figure); the power supply unit, the display unit, and the wireless transmission unit are respectively connected to the processor; the power supply unit is used to supply power to other units; the display unit is used to display the urine volume in the user's bladder, the bladder filling state of the user, the clear sonogram echo of the bladder, and various prompt messages. The scanning frequency of the ultrasonic probe and the release frequency of the coupling agent can also be set on the display unit; the wireless transmission unit is used to send monitoring data to the user in real time. The power supply unit, the display unit, the wireless transmission unit, and the processor can either be centrally arranged inside the housing 1 or arranged outside the housing 1 to form an independent module. This module is connected to the housing 1 through a cable. During use, the housing 1 is fixed on the user's abdomen, and then the independent module is hung beside the bed for the caregiver to observe the change in the user's urine volume.

[0047] In another exemplary embodiment, a method for using the above portable urine volume monitoring device is provided, which is specifically as follows:

[0048] (1) Check the working condition of the movable bearing plate 2. Slide the paddle on the movable bearing plate 2 to the left. After putting the coupling agent release unit 5 into the interior of the housing 1 through the second through hole 22, then slide the paddle on the movable bearing plate 2 to the right, so that the two movable tenons in the second through hole 22 are snapped into the two tenon grooves at the bottom of the coupling agent storage box 51.

[0049] (2) First, place the entire housing 1 on the user's abdomen, and use the ultrasonic probe 32 for preliminary exploration. After the clear ultrasonic image echo of the bladder appears on the display unit, fix the housing 1 with 3M film, and set the position of the current movable bearing plate 2 as the initial position.

[0050] (3) Use the display unit to set the scanning frequency of the ultrasonic probe 32 and the release frequency of the coupling agent (i.e., set the downward pressure of the pusher 511), and at the same time activate the pressure sensor 61 and the infrared distance sensor 64.

[0051] (4) During the operation of the device, the coupling agent release channel 52 releases a quantitative amount of coupling agent between the abdominal skin surface and the ultrasonic probe 32. The ultrasonic probe 32 works intermittently at the set frequency. First, take a picture of the transverse section of the bladder at the deployment position, then the processor 2 controls the drive unit 4 to drive the ultrasonic probe 32 to rotate clockwise by 90 degrees to complete the picture taking of the longitudinal section of the bladder. Finally, the drive unit 4 drives the ultrasonic probe 32 to rotate counterclockwise by 90 degrees, and the ultrasonic probe 32 returns to its original position.

[0052] The processor 2 first determines the anteroposterior diameter, left-right diameter, and vertical diameter of the user's bladder according to the transverse section image and the longitudinal section image of the bladder. That is, after collecting the transverse section image of the bladder, it automatically outlines the bladder area and takes the maximum values of the left-right diameter and the vertical diameter; after collecting the longitudinal section image of the bladder, it automatically outlines the bladder area and takes the maximum value of the anteroposterior diameter; when the bladder area cannot be outlined at individual moments, it is determined that there is basically no urine in the bladder; when the bladder area cannot be outlined for multiple consecutive moments, there may be an abnormality in the portable urine volume monitoring device or the urinary system; then according to the anteroposterior diameter, left-right diameter, vertical diameter, and the bladder volume formula, calculate the bladder volume of the user. The bladder volume formula is:

[0053] C = L1 × L2 × L3 × 50%;

[0054] In the formula, C is the bladder volume (the size of the bladder volume is approximately equal to the urine volume in the bladder), L1 is the anteroposterior diameter, L2 is the left-right diameter, and L3 is the vertical diameter.

[0055] By continuously recording the bladder volume at different times, a bladder volume change rate curve is formed. By comparing the change ratios of the bladder volume in two adjacent times, if there is an obvious decrease in the anteroposterior diameter or volume of the bladder, it means that the user has urinated, and the words "urinated" will appear on the display unit or the corresponding indicator light will be lit.

[0056] (5) During the operation of the device, the pressure sensor 61 measures the longitudinal pressure between the abdominal skin and the movable bearing plate 2, and the infrared ranging sensor 64 measures the height changes of the two hydraulic columns. By continuously monitoring the above data, a pressure change curve and a height change curve are generated.

[0057] Under theoretical conditions, when the bladder is continuously filled, the pressure increases, and the pressure change curve shows an upward trend or a peak plateau; when the bladder is emptied, the pressure change curve shows a downward trend; when the pressure change curve shows an obvious downward trend, the display unit prompts that the bladder is emptied; when the pressure change curve shows a local plateau, it prompts that the bladder volume is stable; when the pressure change curve shows a peak plateau state for a long time, the display unit prompts that the user has urinary retention; when the detection results of several consecutive times are similar, it is considered that the position of the portable urine volume monitoring device is abnormal or the user has urinary retention. In addition, the judgment of the height change curve is basically the same as that of the pressure change curve, so it will not be repeated here. The judgment of the pressure change curve and the height change curve is a parallel judgment method, which jointly makes up for the situation where the bladder cross-sectional image is not detected due to the position problem of the ultrasonic probe 32.

[0058] In summary, the present application mainly has the following advantages:

[0059] The present application adds pressure sensing and infrared ranging functions during the urine volume monitoring process, and realizes all-round monitoring through the changes in pressure and mobility between the ultrasonic probe and the skin; the present application belongs to a portable device, which is specially used for continuously monitoring the urine volume in the bladder; the present application can automatically monitor the anteroposterior diameter of the bladder and evaluate the bladder volume, and can provide real-time feedback on the urination situation of the user according to the changes in the anteroposterior diameter and the bladder volume; the present application has an automatic release function of the coupling agent, which can maintain the device to continuously monitor the bladder volume for a period of time; the present application has self-pressure monitoring and mobility monitoring functions, and realizes continuous monitoring of the bladder filling situation according to the changes in pressure and activity distance between the ultrasonic probe and the skin, achieving the effect of real-time composite continuous monitoring and reducing manual operation.

[0060] All actions of obtaining signals, information or data in the present application are carried out on the premise of complying with the corresponding data protection regulations and policies of the country where it is located and obtaining the authorization given by the owner of the corresponding device.
