Description

Technical Field

[0001] The present invention relates to the technical field of medical sampling instruments, and in particular to a 24-hour urine storage and sampling device. Background Art

[0002] In the field of medical testing, 24-hour urine testing is a crucial clinical examination tool for endocrinology departments. The results of 24-hour uric acid and 24-hour urine protein tests can provide key evidence for doctors to diagnose various endocrine diseases, such as gout and diabetic nephropathy, helping them accurately assess patients' conditions and develop precise treatment plans.

[0003] However, there are many problems with the storage containers currently used in the process of collecting 24-hour urine samples, which seriously affect the accuracy of the test and the patient experience.

[0004] Container specifications are inconsistent: In clinical practice, patients use a wide variety of urine collection containers, lacking a unified standard. Some containers are too small to store urine for 24 hours, forcing patients to frequently change containers. This not only increases operational complexity but also easily leads to urine spillage, resulting in sample loss and environmental contamination.

[0005] Lack of storage function: Most conventional containers lack temperature control. In the hot summer, high indoor temperatures can easily cause chemical changes in urine components and bacterial growth, affecting the accuracy of test results. While the previous method of storing urine in a refrigerator can address the temperature issue to some extent, it is cumbersome, requires patients to travel frequently between home and the hospital, and has limited refrigerator space, posing the risk of cross-contamination.

[0006] Sampling is inconvenient and easy to contaminate: Traditional containers do not have specially designed sampling switches. When taking 2-5ml urine samples for testing, it is often necessary to open the entire container. This not only easily exposes the urine to the air and increases the probability of contamination, but also may cause urine to spill during the operation, affecting the sample quality and the working environment of medical staff.

[0007] Improper opening and seal design: The size and shape of the container opening lack ergonomic considerations, making it inconvenient for both male and female patients and prone to urine splashing. Furthermore, the lid's poor seal fails to effectively prevent odors, impacting both the patient's urine collection experience and the surrounding environment.

[0008] In summary, existing urine storage containers cannot meet the clinical requirements for 24-hour urine specimen storage and collection. There is an urgent need for a specially designed 24-hour urine storage and sampling device to solve the above problems and improve the accuracy and convenience of medical examinations. Summary of the Invention

[0009] To achieve the above object, the present invention is implemented through the following technical solutions:

[0015] Furthermore, the defecation box has square grooves at both the front and rear ends; a urine collection bucket is slidably installed in the front square groove; and a liquid storage bucket is slidably installed in the rear square groove;

[0016] A sealing coating is attached to the upper wall of the square trough;

[0017] Furthermore, the baffle is embedded with a magnet strip, and a sealing coating is provided on the upper end of the baffle; the inner side of the baffle extends beyond the inner side of the upper end of the defecation trough by 4-6 cm, and the splashing urine is blocked by the portion of the inner side of the baffle extending beyond the inner side of the upper end of the defecation trough;

[0018] Furthermore, the cover is embedded with a magnet strip, and the lower end surface of the cover is provided with a sealing coating;

[0019] Furthermore, the air pump is connected to the annular exhaust pipe conduit, and the air pump is controlled by the control module to spray gas along the annular exhaust pipe to clean the surface of the defecation trough, and blow the residual urine into the inside of the three-way valve and into the urine collection bucket;

[0020] Furthermore, the liquid extraction pump is connected to the hospital water source through a conduit, and a conduit is provided to connect to the spray pipes arranged in an array. The liquid extraction pump is controlled by a control module so that the liquid is sprayed out along the spray pipe to clean the surface of the defecation trough and discharged into the liquid storage tank through the three-way valve.

[0021] Furthermore, a liquid inlet tube is provided at the bottom of the syringe, a piston is slidably connected inside the syringe, and a single valve is provided at the liquid storage port at the lower end of the syringe;

[0022] A one-way valve is provided inside the liquid inlet pipe;

[0023] The urine in the urine collection bucket is drawn into the syringe through the movement of the piston, and then the piston is pushed to push the urine into the test tube at the lower end of the syringe.

[0024] The beneficial effects of the present invention are:

[0025] In the present invention, a heat-insulating layer is provided on the inner wall of the urine collecting bucket to prevent the influence of the external temperature on the urine inside the urine collecting bucket, thereby preventing the urine from being infected by bacteria or deteriorating due to excessive temperature, thereby ensuring the stability of the urine sample and improving the accuracy of the test results;

[0026] The syringe is equipped with a liquid inlet tube and a one-way valve at the bottom of the syringe, as well as a single valve at the liquid storage port at the lower end of the syringe. This effectively prevents excessive contact between urine and the outside air when extracting and transferring urine samples, reduces the probability of contamination, ensures the purity of the sample being tested, and provides a guarantee for accurate testing.

[0027] An air pump is connected to the annular exhaust pipe. After defecation, the residual urine on the surface of the defecation trough can be blown into the urine collection bucket, ensuring the accuracy of the 24-hour urine sample.

[0028] A liquid extraction pump and spray pipe are also provided to flush the trough and discharge wastewater into a liquid storage tank. This clean design not only avoids odor and sanitation issues caused by urine residue, but also reduces the burden of subsequent cleaning work, creating a more comfortable use environment for patients and medical staff.

[0050] In this embodiment, the defecation box 1 is made of durable and easy-to-clean materials, including but not limited to ceramics. A defecation trough 101 is provided on the upper part of the defecation box 1 to facilitate the patient to defecate. A baffle 101 is integrally provided on the upper end of the defecation trough 101. A magnet strip is embedded inside the baffle 101 to achieve a stable adsorption connection with the cover 22. A removable annular exhaust pipe 601 is installed in the middle of the lower end of the baffle 101 to purge the surface of the defecation trough 101 after defecation. A plurality of spray pipes are also arranged in an array on the inner side of the baffle 101 to clean the defecation trough 101.

[0051] In this embodiment, the defecation box 1 is a sitting defecation box, which is suitable for both male and female patients, thereby improving the practicality of the device;

[0052] In this embodiment, the control module inside the defecation box 1 is a fixed control instruction, and its control process is as follows:

[0053] When the patient defecates, the control module controls the three-way valve 102 to connect the defecation trough 101 and the urine collecting bucket 4.

Then the control module controls the three-way valve 102 to close the connection between the defecation trough 101 and the urine collecting bucket 4, and opens the connection between the defecation trough 101 and the liquid storage bucket 5, and then controls the liquid extraction pump 3 to extract the cleaning liquid, discharge it along the drainage pipe 301 to flush the defecation trough 101, and collect the waste liquid through the liquid storage bucket 5, and then controls the air pump 6 to work again to drain the residual flushing liquid inside the defecation trough 101;

[0054] In this embodiment, the defecation box 1 has square grooves at both the front and rear ends; a urine collecting bucket 4 is slidably installed in the front square groove; a liquid storage bucket 5 is slidably installed in the rear square groove;

[0055] The upper wall of the square trough is provided with a sealing coating, which abuts against the upper ends of the urine collecting bucket 4 and the liquid storage bucket 5, thereby sealing the space to prevent the odor of urine or waste liquid from volatilizing and spreading;

[0056] In this embodiment, the baffle 101 is embedded with a magnet strip, and a sealing coating is provided on the upper end of the baffle 101; the inner side of the baffle 101 extends beyond the inner side of the upper end of the defecation chute 101 by 4-6 cm, and the splashing urine is blocked by the portion of the inner side of the baffle 101 extending beyond the inner side of the upper end of the defecation chute 101;

[0057] In this embodiment, the cover 2 is embedded with a magnet strip, and the lower end surface of the cover 2 is provided with a sealing coating;

[0058] In this embodiment, the cover 2 is also made of a durable and easy-to-clean material and is embedded with a magnet strip inside. The magnet strip can attract the magnet strip on the baffle 101 to ensure the sealing of the defecation trough 101. The lower end surface of the cover 2 is coated with a sealing coating to further enhance the sealing effect and prevent the spread of urine odor or the spread of bacteria.

[0059] In this embodiment, the air pump 6 is connected to the annular exhaust pipe 601, and the air pump 6 is controlled by the control module to spray gas along the annular exhaust pipe 601 to clean the surface of the defecation trough 101, and blow the residual urine into the three-way valve 102 and into the urine collection bucket 4;

[0060] In this embodiment, the liquid pump 3 is connected to the hospital water source through a conduit, and a conduit is provided to connect to the spray pipes arranged in an array. The liquid pump 3 is controlled by the control module to spray liquid along the spray pipe to clean the surface of the defecation trough 101 and then discharged into the liquid storage tank 5 through the three-way valve 102;

[0061] In this embodiment, a liquid inlet tube 4021 is provided at the bottom of the syringe 402, a piston 4022 is slidably connected inside the syringe 402, and a single valve is provided at the liquid outlet position at the lower end of the syringe 402;

[0062] A one-way valve is provided inside the liquid inlet pipe 4021;

[0063] The urine in the urine collecting bucket 4 is drawn into the syringe 402 by the movement of the piston 4022, and then the piston 4022 is pushed to push the urine into the test tube at the lower end of the syringe 402;

[0064] In this embodiment, the inner wall of the urine collecting bucket 4 is inlaid with an insulating layer 401 to maintain the stability of the urine sample and prevent the external temperature from affecting the urine. A drainage tube 301 is provided at one end of the urine collecting bucket 4, and the drainage tube 301 is connected to the liquid storage port of the syringe 402. The piston 4022 is slidably connected inside the syringe 402 to extract and transfer urine samples. A one-way valve is provided at the liquid storage port at the lower end of the syringe 402 to prevent urine backflow. A one-way valve is provided inside the drainage tube 301 to ensure that urine can only flow in one direction. This avoids the problem of manual dumping of urine for sampling, where the hands of medical staff are easily contaminated with urine and the sampling volume is difficult to control;

[0065] In this embodiment, the capacity of the urine collecting bucket 4 and the liquid storage bucket 5 ranges from 5000 to 6000 ml, which is sufficient for continuous urine retention for 24 hours, avoiding frequent replacement of containers.

[0066] In summary, the 24-hour urine storage and sampling device of the present invention realizes efficient collection, stable storage and convenient sampling of urine samples by integrating key components such as the defecation box 1, the cover 2, the urine collection bucket 4, the liquid pump 3, the liquid storage bucket 5, the three-way valve 102 and the control module.

[0067] The present invention effectively avoids the influence of external temperature on urine samples through the insulation layer 401 inside the urine collecting bucket 4, thereby ensuring the stability of the sample; the syringe 402 and its matching one-way valve and one-way valve design significantly reduce the contact with external air when extracting and transferring urine samples, thereby reducing the risk of contamination; the combined use of the air pump 6 and the annular exhaust pipe 601, the liquid pump 3 and the spray pipe not only realizes the automatic cleaning of the defecation trough 101, but also avoids the odor and hygiene problems caused by urine residue.

[0068] The design of the defecation box 1 conforms to the principles of ergonomics and is convenient for both male and female patients to use; the sealing design of the cover 2 and the baffle 101 effectively prevents the spread of odor, creating a more comfortable use environment for patients.
