Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a 24-hour urine protein urine collection bag. Background Art

[0002] Under normal circumstances, due to the existence of molecular barrier and charge barrier in the glomerular filtration membrane, only a small amount of small-molecule plasma proteins can be selectively filtered. More than 95% of the selectively filtered plasma proteins will be reabsorbed back into the blood circulation. Therefore, only 30-130 mg of trace proteins are excreted into the urine every day. Collecting 24-hour urine for 24-hour urine protein quantitative determination is a direct reflection of the patient's excretion situation in a day, which is the standard for clinical urine protein determination and can assist in the diagnosis, efficacy observation and prognosis judgment of kidney diseases.

[0003] The collection of 24-hour urine can be completed by the patient at home. However, in order to ensure the accuracy of the test results, it is necessary to collect a part of the urine sample each time during the 24 hours. The existing collection method requires the patient to quantitatively measure the urine by themselves through a sampling cup or other measuring containers and then pour it into the urine collection bag. For example, an integrated 24-hour urine protein collection device published in Chinese patent literature, with the authorization announcement number CN211244819U, measures the urine through a measuring bag and then pours it into the urine storage bag through the conduction hole at the top. This collection method has high operation requirements for patients and is not convenient to use. Summary of the Utility Model

[0004] Aiming at the above-mentioned deficiencies of the prior art, the technical problem to be solved by the utility model is: how to provide a 24-hour urine protein urine collection bag with a clever structural design, which can control the urine sampling volume each time and is convenient to operate and use.

[0005] In order to solve the above technical problems, the utility model adopts the following technical scheme:

[0006] A 24-hour urine protein urine collection bag, characterized in that it includes a bag body, the inner cavity of the bag body includes a sampling cavity and a urine storage cavity which are separated left and right, the upper part of the sampling cavity has a metering cavity which is separated, the bottom of the metering cavity has a current-limiting hole communicating with the sampling cavity, and the top of the metering cavity has the same overflow channel as the urine storage cavity; the top of the bag body is connected with a urine inlet channel, and the outlet of the urine inlet channel is located above the metering cavity; the bottom of the bag body is provided with a urine outlet channel, the bag body is provided with a heparin cap connected to the sampling cavity, and the bottom of the sampling cavity is provided with a sampling channel.

[0007] When in use, the patient pours urine into the bag body through the urine inlet channel. Since the outlet of the urine inlet channel is located above the metering cavity, the urine will first enter the metering cavity. Since the flow-through area of ​​the limiting hole at the bottom of the metering cavity is small, the urine cannot quickly pass through the limiting hole, and will quickly fill the metering cavity and quickly flow into the urine storage cavity through the overflow channel, while the urine remaining in the metering cavity slowly flows into the sampling cavity through the limiting hole. The preservative can be easily injected into the sampling cavity through the heparin cap; during testing, the urine sample is obtained through the sampling channel. During each urine collection process, the amount of urine flowing into the sampling cavity is equal to the sum of the volume of the metering cavity and the amount of urine flowing through the limiting hole during the overflow process. In this way, each urine collection within 24 hours can collect a portion of the urine sample, and the amount of urine sample collected each time is also similar, thereby ensuring that the urine sample comes from urine at different times within 24 hours, which is conducive to ensuring the accuracy of the test results. The above structure is ingenious, and no additional measurement is required. Urine diversion and sampling can be completed by simply pouring urine into the urine inlet channel, which is conducive to controlling the sampling volume.

[0008] Furthermore, the diameter of the flow limiting hole is 2-4 mm.

[0009] Furthermore, the top of the sampling cavity has an overflow hole connected to the urine storage cavity.

[0010] In this way, once the number of urine collection times increases, since the amount of urine sample collected each time is similar, the total amount of urine sample will exceed the capacity of the sampling cavity, and can flow into the urine storage cavity through the overflow hole.

[0011] Furthermore, a temporary storage bag made of elastic material is provided on the side wall of the sampling cavity, and the heparin cap is communicated with the temporary storage cavity in the temporary storage bag; and a one-way injection channel that can be squeezed and connected is provided between the bottom of the temporary storage bag and the sampling cavity.

[0012] In this way, after the patient receives the urine collection bag, the toluene preservative can be injected into the temporary storage cavity in advance, which can prevent the patient from directly contacting the toluene preservative and prevent the toluene preservative from staying in the temporary storage cavity for a long time. After each urine collection, the temporary storage bag is squeezed to squeeze the toluene preservative in the temporary storage cavity into the sampling cavity through the injection channel. After squeezing, the temporary storage bag will remain in a deflated state because the one-way injection channel cannot be replenished in the reverse direction.

[0013] Furthermore, the one-way injection channel is an injection hole arranged on the elastic material.

[0014] In this way, the elastic material will be stretched open during squeezing, thereby opening the injection hole, making it easier to squeeze the toluene preservative into the sampling cavity.

[0015] Furthermore, the temporary storage bag is tubular and is vertically arranged in the sampling cavity.

[0016] Further, the surface of the temporary storage bladder is provided with scale lines arranged along the length direction.

[0017] In this way, the dosage of toluene antiseptic squeezed into the sampling cavity each time can be calculated through the scale lines.

[0018] Further, the inlet of the urine inlet channel is provided with a funnel-shaped material receiving port.

[0019] Further, the sampling channel is a flexible hose connected to the bag body, and a clip for opening and closing the flexible hose is provided on the flexible hose.

[0020] Further, hanging ropes are respectively arranged on both sides of the upper end of the bag body.

[0021] In summary, the utility model has the advantages of ingenious structural design, capable of controlling the urine sampling amount each time, and convenient to operate and use. Description of the Drawings

[0022] Figure 1 It is a schematic structural diagram of this embodiment.

[0023] Figure 2 It is another schematic structural diagram of this embodiment. Detailed Embodiment

[0024] The following further elaborates on the present utility model in conjunction with embodiments.

[0025] During specific implementation: As Figure 1 shown, a 24-hour urinary protein urine collection bag includes a bag body 1. The inner cavity of the bag body 1 includes a sampling cavity 11 and a urine storage cavity 12 that are separated left and right. Above the sampling cavity 11, there is a measurement cavity 13 that is separated. The bottom of the measurement cavity 13 has a flow-limiting hole 14 communicating with the sampling cavity 11. The top of the measurement cavity 13 has an overflow channel 15 that is the same as the urine storage cavity 12; the top of the bag body 1 is connected to a urine inlet channel 2, and the outlet of the urine inlet channel 2 is located above the measurement cavity 13; the bottom of the bag body 1 is provided with a urine outlet channel 3. A heparin cap 16 connected to the sampling cavity 11 is provided on the bag body 1. The bottom of the sampling cavity 11 is provided with a sampling channel 4. The sampling channel 4 is a flexible hose connected to the bag body 1, and a clip (not shown in the figure) for opening and closing the flexible hose is provided on the flexible hose. Hanging ropes 6 are respectively arranged on both sides of the upper end of the bag body 1. The inlet of the urine inlet channel 2 is provided with a funnel-shaped material receiving port 5. In order to control the flow rate and flow volume of the measurement cavity 13 entering the sampling cavity 11, in this embodiment, the diameter of the flow-limiting hole 14 is 2 mm.

[0026] To meet the need for multiple samplings, the volume of the sampling chamber 11 is 5 to 7 times that of the metering chamber 13, which can meet the need for 5 to 6 samplings. At the same time, the top of the sampling chamber 11 is provided with an overflow hole 19 communicating with the urine storage chamber 12. Once the number of urine collections is excessive and the total urine sample volume exceeds the volume of the sampling chamber, it can flow into the urine storage chamber through the overflow hole.

[0027] To prevent the patient from directly contacting the toluene preservative, a temporary storage bladder 17 made of an elastic material is provided on the side wall of the sampling chamber 11, and the heparin cap 16 communicates with the temporary storage chamber in the temporary storage bladder 17; there is a squeezable and conductive one-way injection channel 18 between the bottom of the temporary storage bladder 17 and the sampling chamber 11. In this embodiment, the temporary storage bladder 17 is tubular and is vertically arranged in the sampling chamber 11, and the surface of the temporary storage bladder 17 is provided with scale lines arranged along the length direction; the one-way injection channel 18 is an injection hole provided on the elastic material. In this way, after the patient gets the urine collection bag, the nurse can inject the toluene preservative into the temporary storage chamber of the temporary storage bladder through the heparin cap 16. After each urine collection, by squeezing the temporary storage bladder, the toluene preservative in the temporary storage chamber is squeezed into the sampling chamber through the injection channel. After squeezing, since the one-way injection channel cannot be replenished in the reverse direction, the temporary storage bladder will remain deflated. Specifically in implementation, a balloon can be considered to be connected and arranged at the upper end of the temporary storage bladder 17, and a one-way air inlet valve is arranged on the balloon. As Figure 2 shown, by squeezing the balloon, the toluene preservative in the temporary storage bladder 17 can be squeezed into the sampling chamber 11. After releasing the balloon, air enters the balloon through the one-way air inlet valve, and both the temporary storage bladder 17 and the balloon return to their original states.

[0028] When using the 24-hour urinary protein urine collection bag of this embodiment, the patient hangs the urine collection bag at a suitable position through the hanging rope 6. After each urination, the collected urine is poured into the urine collection bag from the feeding port 5, and the urine flows into the metering chamber 13 through the urine inlet channel 2. Since the flow-limiting hole is small, the metering chamber will be quickly filled, and the urine will quickly flow into the urine storage chamber through the overflow channel. The remaining urine that has not overflowed slowly flows into the sampling chamber 11 through the flow-limiting hole 14. The patient can squeeze the temporary storage bladder 17 to squeeze the toluene preservative into the sampling chamber 11 through the one-way injection channel 18. The whole operation is simple and fast. When using the urine collection bag of this embodiment, during each urine collection process, the amount of urine flowing into the sampling chamber is equal to the sum of the volume of the metering chamber and the amount of urine flowing through the flow-limiting hole during the overflow process. In this way, a part of the urine sample can be collected during each urine collection within 24 hours, and the amount of urine sample collected each time is also similar, so as to ensure that the urine sample comes from the urine at different time periods within 24 hours, which is beneficial to ensuring the accuracy of the test results.

[0029] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
