Description

Technical Field

[0001] This disclosure relates to the field of data collection technology, specifically to a midstream urine collection device and an excrement collection system. Background Technology

[0002] Midstream urine is often used in urinalysis because it reduces contamination from bacteria and other substances in and around the urethra, which can affect the accuracy of test results. Initial urine may be contaminated at the urethral opening or urethra, leading to inaccurate results, while terminal urine may contain more sediment due to its longer retention time in the bladder, resulting in more severe results. Therefore, collecting midstream urine minimizes interference, resulting in a purer sample that more accurately reflects the condition inside the bladder. In other words, midstream urine better represents the actual condition of the urinary system, which is very helpful for clinical diagnosis.

[0003] In related technologies, midstream urine collection cups are prone to contamination, which can affect the accuracy of urine test results. Alternatively, patients may not properly understand the collection method; for example, some patients lack sufficient knowledge of how to correctly collect midstream urine, resulting in urine samples that do not meet requirements.

[0004] Therefore, providing a device that is easy to operate and can reduce midstream urine contamination during the collection process is an urgent problem to be solved. Utility Model Content

[0005] In order to overcome at least one of the many problems in the related art, the first aspect of this disclosure provides a midstream urine collection device.

[0006] The midstream urine collection device includes:

[0007] A funnel-shaped collecting section, wherein the upper part of the funnel-shaped collecting section includes an inlet;

[0008] An upper fixing seat is connected to the bottom of the funnel collecting part, and the bottom outlet of the funnel collecting part is located inside the upper fixing seat;

[0009] The upper fixed base includes a first connecting channel inside, and the inlet of the first connecting channel is connected to the bottom outlet of the funnel collecting part;

[0010] It also includes a lower fixing seat, which includes a second connecting channel and a third connecting channel, wherein the inlet of the second connecting channel is connected to the outlet of the first connecting channel;

[0011] The outlet of the third connection channel is connected to the collecting element;

[0012] The urine sequentially passes through the funnel collection section and the first connecting channel, then fills the second connecting channel, and finally overflows into the third connecting channel to fill the collection element with the middle section of urine.

[0013] In some optional embodiments, a flow regulator is also included, which is disposed at the outlet of the second connecting channel;

[0014] The flow regulating component is provided with a flow passage hole to drain the initial urine.

[0015] In some optional embodiments, the outlet of the first connecting channel extends into the inlet of the second connecting channel;

[0016] When the midstream urine collection device is placed vertically, the height of the outlet of the first connecting channel is lower than the inlet of the third connecting channel.

[0017] In some optional embodiments, the upper part of the lower fixing seat is provided with a cavity, and the cavity is respectively connected to the second connecting channel and the third connecting channel;

[0018] In operation, the midstream urine flows sequentially through the third connecting channel and the cavity before overflowing into the second connecting channel.

[0019] In some optional embodiments, the upper fixing seat is provided with a drainage channel for draining urine overflowing from the collection element.

[0020] In some optional embodiments, the upper fixing seat is provided with a connecting hole, one side of which connects to the upper cavity of the lower fixing seat, and the other side connects to the drainage channel of the upper fixing seat.

[0021] In some optional embodiments, the drainage channel includes an inlet and an outlet; wherein, when the mid-section urine collection device is placed vertically, the outlet height of the first connecting channel is lower than the inlet of the drainage channel.

[0022] In some alternative embodiments, the collecting element is detachably sleeved with the third connecting channel.

[0023] In some alternative embodiments, the funnel collecting section is provided with a handle.

[0024] Another aspect of the present invention provides an excrement collection system, wherein the collection system integrates a midstream urine collection device according to any of the first aspects of the present invention.

[0025] The technical solution disclosed herein has the following advantages or beneficial effects:

[0026] (1) In some embodiments, urine sequentially passes through the funnel collection section and the first connecting channel to fill the second connecting channel, and then overflows into the third connecting channel to fill the collection element with midstream urine. That is, by optimizing the internal pipeline structure design, the initial urine and midstream urine can be effectively separated, so that the initial urine is effectively separated and only the midstream urine enters the urine collection device.

[0027] (2) In some embodiments, the flow regulating element is located at the outlet of the second connecting channel; the flow regulating element is provided with a flow passage to drain the initial urine. Since the second connecting channel is always in a draining function, the liquid in the second connecting channel always tends to flow towards the outlet of the second connecting channel, thereby preventing the initial urine from flowing back into the collecting element and effectively eliminating the pollution problem caused by the mixing of the initial urine and the middle urine.

[0037] As described in the background section, the collection devices in the related art have many inconveniences. To address at least one of the problems in the related art, this disclosure provides a midstream urine collection device in a first aspect. The midstream urine collection device includes: a funnel collecting section, the upper part of which includes an inlet; an upper fixing seat connected to the bottom of the funnel collecting section, with the bottom outlet of the funnel collecting section located inside the upper fixing seat; the interior of the upper fixing seat includes a first connecting channel, the inlet of which communicates with the bottom outlet of the funnel collecting section; and a lower fixing seat, which includes a second connecting channel and a third connecting channel, the inlet of which communicates with the outlet of the first connecting channel; the outlet of the third connecting channel communicates with a collection element; the urine sequentially passes through the funnel collecting section and the first connecting channel, filling the second connecting channel, and then overflows into the third connecting channel to fill the collection element with midstream urine.

[0038] See Figure 1 This image shows an isometric view of a midstream urine collection device according to an embodiment of the present invention. The device is used to collect midstream urine, minimizing or essentially eliminating the collection of initial and final urine streams. In practice, the outer third of the urethra in healthy individuals may contain some protein and white blood cells. Midstream urine, due to its larger volume and faster flow rate, is less susceptible to contamination compared to initial and final urine streams. Midstream urine, compared to initial and final urine streams, better represents the true state of urine in the bladder, and it avoids interfering substances such as dietary glycosuria or medications like vitamin C, which can affect urine test results. Midstream urine can more accurately detect diseases such as urinary tract infections, kidney stones, kidney disease, diabetes, and bacterial infections. To improve the accuracy of midstream urine collection and avoid contamination issues, the present invention… Figure 1 The collection device provided in the illustrated embodiment can effectively separate the initial urine, midstream urine and final urine, and effectively collect the midstream urine.

[0039] like Figure 1 As shown, the midstream urine collection device generally includes a funnel collection section 300, an upper fixed base 200, a lower fixed base 100, and a collection element 400.

[0040] The funnel-shaped collecting unit 300 includes an inlet at the top and an outlet at the bottom. In use, the inlet faces upwards to allow urine to enter the device through the open inlet, which is wider at the top and narrower at the bottom. This effectively avoids alignment issues during urine collection and also prevents contamination of the collector's hands.

[0041] like Figure 2 The diagram shows a cross-sectional view of a midstream urine collection device. This diagram clearly illustrates the assembly relationship between the funnel collecting section 300, the upper fixing seat 200, the lower fixing seat 100, and the collecting element 400. Specifically, the upper fixing seat 200 is connected to the bottom of the funnel collecting section, and the bottom outlet of the funnel collecting section is located inside the upper fixing seat. In practice, the upper fixing seat 200 has a generally cylindrical outer contour, while its interior is hollow. The cylindrical outer contour is composed of thin walls 201. The top opening formed by the thin walls 201 mates with the funnel collecting section 300. Furthermore, a first connecting channel is also provided inside the upper fixing seat. Figure 2 As shown, a portion of the first connecting channel is formed on the thin wall 201, and another portion extends downward from the thin wall 201 to form a pipe shape. The top of the first connecting channel is cylindrical, thereby connecting to the bottom outlet of the funnel collecting part. In some embodiments, the bottom opening 302 of the funnel collecting part is configured as a pipe to fit and connect with the top of the first connecting pipe. Preferably, the bottom of the first connecting channel is provided with a tapered outlet 202, allowing urine to flow smoothly into the next stage.

[0042] like Figure 1 and 3In the illustrated embodiment, the device further includes a lower fixing base 100, which is sleeved and connected to the upper fixing base 200. The lower fixing base 100 includes a second connecting channel 101 and a third connecting channel 102. The second connecting channel 101 and the third connecting channel 102 are separately disposed and are used to collect initial urine and midstream urine, respectively. Specifically, the inlet of the second connecting channel 101 communicates with the outlet 202 of the first connecting channel. The outlet of the third connecting channel 102 communicates with the collecting element 400. When the operator uses the device, the initial urine discharged sequentially passes through the inlet of the funnel collecting part, the first connecting channel, and then enters the second connecting channel 101. The urine sequentially passes through the funnel collecting part and the first connecting channel, filling the second connecting channel, and then overflows into the third connecting channel to fill the collecting element with midstream urine. Therefore, the present invention... Figure 1 In the illustrated embodiment, by optimizing the internal tubing structure design, the initial and midstream urine can be effectively separated, ensuring that only the midstream urine is collected and enters the urine collection device. In some embodiments, the collection element can be a test tube.

[0043] In some optional embodiments, a flow regulator is further included, which is disposed at the outlet of the second connecting channel; the flow regulator is provided with a flow passage to drain the initial urine stream. Figure 1 and 2 In the illustrated embodiment, the flow regulator 500 is disposed on the outlet of the second connecting channel. Specifically, the flow regulator can be detachable, allowing for flexible selection based on the needs of the user. For example, adults with high urine flow can choose a flow regulator with a large flow capacity, while children and other individuals with low urine flow can choose a flow regulator with a small flow capacity. Preferably, the flow regulator can be snap-fitted into the second connecting channel. In some embodiments, the flow regulator is provided with flow holes to drain the initial urine. The size and number of flow holes can be flexibly adjusted according to the different urine flow rates of the user. Due to the presence of the flow holes, the initial urine entering the second connecting channel cannot remain for a long time. That is, as the initial urine fills the second connecting channel and the middle urine overflows into the collecting element, it continuously flows out of the collecting device through the flow holes. Because the second connecting channel is always in a draining function, the liquid in the second connecting channel always tends to flow towards the outlet of the second connecting channel, thereby preventing the initial urine from flowing back into the collection element and effectively eliminating the pollution problem caused by the mixing of the initial urine and the middle urine.

[0044] In some optional embodiments, the outlet of the first connecting channel extends into the inlet of the second connecting channel; when the mid-section urine collection device is placed vertically, the height of the outlet of the first connecting channel is lower than the inlet of the third connecting channel. Figure 1 and 2 In the illustrated embodiment, because the outlet 202 of the first connecting channel is in a constricted state and is inserted into the inlet of the second connecting channel, urine is accelerated into the second connecting channel at the outlet 202, preventing the initial urine from flowing back into the collection element. Preferably, the midstream urine collection device is placed in a vertical position (i.e., attached to...). Figure 2 (As shown in the cross-sectional view), the height of the outlet of the first connecting channel is lower than the inlet of the third connecting channel, so that the liquid level at the outlet of the first connecting channel is lower than the inlet height of the third connecting channel. This effectively ensures that during the initial collection stage, the initial urine can only enter the second connecting channel due to the height difference in liquid level, and cannot enter the third connecting channel, thus avoiding the problem of initial urine contaminating the middle urine.

[0045] In some optional embodiments, the upper part of the lower fixing seat is provided with a cavity, which is connected to the second connecting channel and the third connecting channel respectively; in the working state, the midstream urine flows sequentially through the third connecting channel and the cavity and then overflows into the second connecting channel. Figure 2 In the illustrated embodiment, the upper part of the lower fixing seat is provided with a cavity, which connects the second connecting channel and the third connecting channel. This allows the midstream urine, after leaving the outlet of the first connecting channel, to flow through the cavity to the third connecting channel. Although the second and third connecting channels are connected here, because the outlet height of the first connecting channel is lower than the inlet height of the third connecting channel, and due to the leakage effect of the flow regulating element, the initial urine collected in the second connecting channel cannot flow back into the collecting element, thus avoiding the problem of initial urine contaminating the midstream urine.

[0046] In some optional embodiments, the upper fixing seat is provided with a drainage channel 204 for discharging urine overflowing from the collecting element. As described above, one objective of the present invention is to collect midstream urine; therefore, it is necessary to separate the initial, midstream, and final stages of urine. In the embodiments described above, the initial and midstream urine have been separated, avoiding contamination problems caused by their mixing. In this embodiment, a drainage channel is further provided on the upper fixing seat, so that after the collecting element has collected the midstream urine, the final stage of urine is discharged from the collecting device through the drainage channel, preventing the final stage of urine from mixing with the midstream urine.

[0047] In some optional embodiments, the upper fixing seat is provided with a connecting hole 205, one side of which connects to the upper cavity of the lower fixing seat, and the other side connects to the drainage channel of the upper fixing seat. For example... Figure 2 In the illustrated embodiment, in order to guide the final urine from the lower fixing seat to the drainage channel, a connecting hole 205 needs to be provided on the upper fixing seat to connect the pipeline connected to the collecting element to the drainage channel.

[0048] In some optional embodiments, the drainage channel includes an inlet 203 and an outlet; wherein, when the mid-section urine collection device is placed vertically, the outlet height of the first connecting channel is lower than the inlet of the drainage channel. Figure 1 and 2 In the embodiments shown, to avoid unnecessary entry of midstream urine into the drainage channel, which could lead to insufficient midstream urine collection, some embodiments employ a reasonable setting of the relationship between the height of the drainage channel inlet and the height of the first connecting channel outlet. This ensures that midstream urine can only enter the drainage channel and be discharged to the outside of the device after the collection device is fully filled, taking advantage of changes in the liquid level.

[0049] In some optional embodiments, the collecting element is detachably sleeved with the third connecting channel. For example... Figure 4 As shown, it presents a cross-sectional view of the collection element being removed after urine collection is complete. Figure 5 The diagram shows a sample of the collecting elements, which is in a test tube. (For example...) Figure 4 As shown, the third connection channel 102 includes an outlet 103, which is sleeved and connected to the inlet 402 of the collecting element 400, thereby facilitating the connection and disassembly of the two. In some embodiments, the connection strength between the two can be controlled by controlling the pipe diameter and / or the sleeve depth. For example, increasing the length of the sleeve section 401 of the test tube can increase the connection strength.

[0050] In some optional embodiments, the funnel collecting section is provided with a handle. For example... Figure 1 and 2 In the described embodiment, the funnel collecting part has a large inner cavity 301 and a thin-walled structure, making it inconvenient for operators to operate directly by hand. Therefore, in a preferred embodiment, a handle 303 is provided on one side of the funnel collecting part to facilitate the operator's grip and avoid hand contamination during urine collection.

[0051] Another aspect of the present invention provides an excrement collection system, which integrates a midstream urine collection device according to any of the first aspects of the present invention. In practice, the operator can use only the urine collection device to collect urine. In other embodiments, the urine collection device can also be integrated into some collection systems; the systems include, but are not limited to, smart toilets. For example, the midstream urine collection device can be placed in a smart toilet, thereby avoiding the problem of manually holding the urine collection device. Accordingly, the system can be provided with a corresponding urine collection device storage part to facilitate the stable placement of the urine collection device in the system. During use, the operator only needs to place the urine collection device in the correct position as instructed to excrete urine into the urine collection device.

[0052] The specific embodiments described above do not constitute a limitation on the scope of protection of this disclosure. Those skilled in the art, after considering the specification and practicing the technical solutions disclosed in this application, will readily conceive of other embodiments of this disclosure. This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary technical means in the art not disclosed in this disclosure. The specification and embodiments are considered exemplary only, and the true scope and spirit of this disclosure are indicated by the following claims.

The scope of this disclosure is limited only by the appended claims.
