[0033] In order to more understand the technical content of the utility model, specific embodiments are raised and cooperate with the following drawings.It needs to be explained that the flow and urine flow rate parameters used are only for example description, and do not have medical guiding significance.

[0034] Embodiment 1

[0035] As Figure 1 The urine flow rate detection device of the utility model, including lower shell 10, upper shell 20 and second container 30, lower shell 10 and upper shell 20 are all plastic shell, and upper shell 20 is located above lower shell 10, and first container 12 is arranged in the inside of lower shell 10, and upper shell 20 is detachably connected to the top of lower shell 10.

[0036] As Figure 2 Four pin shafts 24 are arranged on the bottom of upper shell 20, and the insertion hole is arranged on lower shell 10, and when installing upper shell 20, the pin shaft 24 is clamped into the insertion hole.

[0037] Transparent cover plate 11 is arranged on the outside of lower shell 10, and the transparent cover plate 11 can be opened, so that the first container 12 in the inside is taken and placed, and the first container is used to collect the urine flowing from the second container 30, and can be poured after being full.

[0038] Further, the second container 30 is connected to the lower shell 10 and is located in the inside of the upper shell 20, the bottom of the second container 30 is provided with a drain pipe 35, the drain pipe 35 is located above the first container 12, the drain pipe 35 is provided with a flow valve 34 for controlling the maximum flow of the second container 30 to the first container 12.

[0039] The upper shell 20 is provided with a liquid inlet guide pipe 22, and the side wall of the upper shell 20 is provided with a window 202, wherein the upper end of the second container 30 is connected with the lower end of the liquid inlet guide pipe 22, the liquid inlet guide pipe 22 is configured to have a smooth inner surface, and the inner surface is arranged as an inwardly recessed arc surface, which can be tangent to the trajectory of the urine entering from the liquid inlet 21.

[0040] In this way, the examinee can urinate towards the liquid inlet 21, and the urine enters the second container 30 along the liquid inlet guide pipe 22 and finally flows into the first container 12 through the drain pipe 35 for urine collection, and in this process, since the flow valve 34 controls the maximum discharge flow of the second container 30, the maximum discharge flow of the drain pipe 35 can be adjusted to determine whether the urine flow rate of the examinee is qualified, and in addition, the examinee or medical staff can observe the maximum urine accumulation in the second container 30 through the window 202.

[0041] Suppose the flow rate of the flow valve 34 is set to 13 ml / s, if the second container 30 accumulates urine when the person under test is urinating, it means that the urine flow rate of the person under test is greater than 13 ml / s.

[0042] The second container 30 is provided with a scale mark, which includes at least two mark lines. After the second container 30 continuously receives urine, if the second container 30 accumulates urine, it means that the maximum urine flow rate entering the second container 30 is greater than the first urine flow rate. When the maximum urine accumulation in the second container 30 is higher than the first mark line, it means that the maximum urine flow rate entering the second container 30 is greater than the second urine flow rate. When the maximum urine accumulation in the second container 30 is higher than the second mark line, it means that the maximum urine flow rate entering the second container 30 is greater than the third urine flow rate.

[0043] Suppose the person under test is a 40-60-year-old male, according to existing medical experience, the first urine flow rate is set to 13 ml / s, the second urine flow rate is set to 18 ml / s, and the third urine flow rate is set to 22 ml / s. Urine flow rate less than 13 ml / s is obviously a urination disorder, between 13 ml / s and 18 ml / s is a urination disorder, between 18 ml / s and 22 ml / s is a possible urination disorder, and greater than 22 ml / s is no urination disorder.

[0044] The flow rate of the flow valve 34 is set to 13 ml / s, and the first mark line is set at the a volume of the second container 30 (corresponding to the second urine flow rate mark line) and the second mark line is set at the b volume of the second container 30 (corresponding to the third urine flow rate mark line) according to the existing medical experience of different people's urination time, urine flow rate and the size of the second container.

[0045] During detection, the person under test urinates, and during the entire urination process, if the second container 30 does not accumulate urine, it is judged that the urine flow rate of the person under test is less than 13 ml / s, and there is a obvious urination disorder; if the maximum urine accumulation in the second container 30 is below the first mark line, it is roughly judged that the urine flow rate of the person under test is between 13 ml / s and 18 ml / s, and there is a urination disorder; if the maximum urine accumulation in the second container 30 is between the first mark line and the second mark line, it is roughly judged that the urine flow rate of the person under test is between 18 ml / s and 22 ml / s, and there is a possible urination disorder; if the maximum urine accumulation in the second container 30 is higher than the second mark line, it is roughly judged that the urine flow rate of the person under test is greater than 22 ml / s, and there is no urination disorder.

[0046] Further, the window 202 is arranged on at least three side walls of the upper shell 20.

[0047] In this way, when the person under test urinates, the maximum urine accumulation in the second container 30 can be observed by the accompanying person or medical staff through the window 202 to determine whether the person under test has a urination disorder and the degree of the urination disorder.

[0048] In an optional embodiment, the upper shell 20 is provided with an inclined surface 201, and the liquid inlet end of the liquid inlet pipe 22 is connected to the inclined surface 201. The angle between the inclined surface 201 and the horizontal plane support is greater than 70 degrees.

[0049] It can be understood that when the person under test urinates, the inclined liquid inlet 21 is beneficial for the urine to enter the liquid inlet pipe 22 along the inner wall of the liquid inlet pipe 22. Since the urine has impact force, when the urine enters the liquid inlet pipe 22 along the inner wall of the liquid inlet pipe 22, it can flow down along the inner wall of the liquid inlet pipe 22, thereby reducing the foam generated by the urine emptying into the second container 30 and the disturbance to the liquid level fluctuation.

[0050] In a more preferred embodiment, as shown in Figure 3 the liquid inlet pipe 22 includes a first arc surface 221 and a second arc surface 222. The first arc surface 221 is away from the inclined surface 201, and the second arc surface 222 is close to the inclined surface 201. The curvature of the first arc surface 221 is smaller than the curvature of the second arc surface 222.

[0051] When the person under test urinates into the liquid inlet 21, the urine can be attached to the surface of the first arc surface 221 in a tangential direction, so that the urine flows smoothly downward. The last segment of urine can also flow smoothly downward through the inner wall of the second arc surface 222, which can avoid uneven distribution of urine caused by impact, resulting in inaccurate urine flow rate.

[0052] As shown in Figure 4 the second container 30 is configured to include a first part 31 and a second part 32. The first part 31 is located below the liquid inlet pipe 22, and the side wall of the second container 30 is perpendicular to the horizontal plane. The angle between the first arc surface 221 and the side wall of the second container 30 is obtuse. The lower part of the second arc surface 222 smoothly connects to the side wall of the second container 30, and the second part 32 is close to the window 202.

[0053] The first part 31 is connected to the lower part of the liquid inlet pipe 22 and connected by a sealing ring 23 therebetween, so as to prevent the urine flowing along the wall of the liquid inlet pipe 22 from entering the outside of the second container 30. Since the urine flows to the first part 31 through the lower end of the liquid inlet pipe 22 and gradually accumulates in the second container 30, there is no urine flowing above the second part 32 during this process. Therefore, the liquid level in the second part 32 is more stable and is not easily affected by water droplets to cause fluctuations in the liquid level.

[0054] Furthermore, the first part 31 and the second part 32 of the second container 30 are separated by a filter screen 33 with a mesh size of 32 to 64, and the scale marks are set on the side of the second part 32 near the viewing window 202.

[0055] In this way, the foam generated in the first part 31 can be filtered or punctured by the filter screen 33, preventing the foam from affecting the actual liquid level in the second part 32.

[0056] Example 2

[0057] A method for detecting urinary flow rate, using the portable urinary flow rate detection device of Example 1, includes the following steps:

[0058] Step 1: Adjust the opening of flow valve 34;

[0059] Step 2: The person to be tested urinates towards the inlet 21, allowing the urine to flow into the second container 30 through the inlet tube 22;

[0060] Step 3: During the entire urination process, observe the maximum cumulative amount of urine in the second container 30 through window 202;

[0061] Step 4: If no urine accumulates in the second container 30, the urine flow rate of the examinee is determined to be less than 13 ml / s, indicating significant urination obstruction. If the maximum cumulative urine volume in the second container 30 is below the first mark, the urine flow rate of the examinee is roughly determined to be between 13 ml / s and 18 ml / s, indicating urination obstruction. If the maximum cumulative urine volume in the second container 30 is between the first and second marks, the urine flow rate of the examinee is roughly determined to be between 18 ml / s and 22 ml / s, indicating possible urination obstruction. If the maximum cumulative urine volume in the second container 30 is above the second mark, the urine flow rate of the examinee is roughly determined to be greater than 22 ml / s, indicating no urination obstruction.

[0062] In this embodiment, the height of the accumulated urine in the second container 30 is mainly observed by the family members or medical staff accompanying the examinee through the viewing window 202, which serves as the basis for judging the urine flow rate. The first and second marker lines can also be used as rough evaluation standards for different age groups. If the examinee is over 60 years old, as long as the height of the maximum accumulated urine in the second container 30 is higher than the first marker line, urinary dysfunction can be basically ruled out. If the examinee is between 40 and 60 years old, as long as the accumulated urine in the second container 30 exceeds the second marker line, urinary dysfunction can be basically ruled out.

[0063] Example 3

[0064] A portable urine flow rate detection device also includes a laser sensor 40 and a controller 50.

[0065] The urine flow rate detection device differs from the above in that the urine flow rate detection device proposed in the embodiment uses a laser sensor 40 to detect the liquid level.

[0066] Further, the laser sensor 40 is arranged on both sides of the second part 32 to detect the height of the urine in the second part 32, and the controller 50 includes a multi-color signal lamp, and the controller 50 is arranged to display different colors of the signal lamp according to the preset urine height.

[0067] It can be understood that, since the second part 32 does not have the wall-adhering and downward flowing urine, only includes accumulated urine and air, therefore, the liquid level of the urine is obviously layered, and the position of the liquid level height can be detected by the laser sensor 40.

[0068] The laser sensor 40 includes a light emitter 41 and a light receiver 42, the light emitter 41 is a linear light source, and the light receiver 42 is a linearly distributed optical fiber receiver that can receive the light signal of each height layer. For example, if the urine is at the height of the a capacity mark line in the container, the light signal below the a capacity mark line and the light signal above the a capacity mark line are different, which is used as the basis for judging the liquid level height.

[0069] Further, the controller 50 presets parameters of different gears according to the opening of the flow valve 34, and each gear parameter includes a minimum parameter and a maximum parameter. It should be understood that, since the standards for whether the urine flow rate meets the standard are different for different age groups, the controller 50 gives corresponding virtual marking lines for different age groups, and each age group corresponds to a different opening range of the flow valve 34.

[0070] Further, the multi-color signal lamp of the controller 50 includes a red lamp, a blue lamp and a green lamp, when the liquid level is lower than the minimum parameter, the controller 50 controls the red lamp to light, when the liquid level is between the minimum parameter and the maximum parameter, the controller 50 controls the blue lamp to light, and if the liquid level is higher than the maximum parameter, the controller 50 controls the green lamp to light. Different colors of the lamp correspond to different maximum urine accumulation detection values.

[0071] It should be understood that the opening of the flow valve 34 can be set to 100%, 75%, 50% and the like, and each opening corresponds to a person to be detected in an age group, and the controller 50 sets different virtual liquid levels according to the standard.

[0072] Embodiment 4

[0073] A urine flow rate detection method using the portable urine flow rate detection device in embodiment 3 for detection, including the following steps:

[0074] Step 1, adjusting the opening of the flow valve 34 according to the characteristics of the target person to be detected;

[0075] Step 2, the person to be tested urinates towards the liquid inlet 21, and the urine flows along the liquid inlet conduit 22 into the second container 30;

[0076] Step 3, the controller 50 controls the signal light to display different colors according to the liquid level of the urine, wherein the green light indicates no obstacle, the blue light indicates suspicious existence of obstacle, and the red light indicates dysfunction.

[0077] Different from the above detection method, the detection method shown in the embodiment does not need observation by the person to be tested, the accompanying person or the medical staff, and after the person to be tested urinates, the person to be tested can judge whether there is an obstacle in urination according to the color of the signal light.

[0078] In combination with the above embodiments, the application sets a container capable of controlling the maximum flow of discharged liquid. By controlling the maximum flow of discharged liquid, the accumulated amount of urine left in the container can be controlled. The maximum height that the accumulated amount of urine can reach can be used as an evaluation basis for the urine flow rate. In the application, only a specific liquid level height is marked on the surface of the container. By comparing whether the urine discharged by the person to be tested is higher than the liquid level, a rough detection basis for whether the urination of the person to be tested is an obstacle is made. It is not necessary to analyze the change of the urine flow rate in the complete urination process. The urination function of the person to be tested can be effectively evaluated in a rough qualitative manner. The device has a simple structure, low cost, convenient operation and maintenance, and is beneficial to popularization and application.
