Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a mid-stream urine sampling device. Background Art

[0002] Urine testing is a commonly used diagnostic method in clinical medicine. By analyzing the various components in urine, it can help doctors judge the patient's health status. However, accurately obtaining the quality of urine samples is crucial to the test results. In clinical practice, in order to avoid impurities in the sample (such as bacteria in the first-stream urine or metabolites in the last-stream urine) affecting the test results, it is usually necessary to collect midstream urine. Midstream urine refers to the middle part of the urination process. This part of urine is more representative of the patient's actual urine condition than the first and last sections.

[0003] Existing urine sampling methods typically require manual operation, requiring patients to adjust their urination speed and timing according to medical staff's instructions. This is cumbersome and prone to sample contamination. Furthermore, in certain special circumstances (such as children, the elderly, or patients with limited mobility), self-control of the sampling process is even more difficult, posing a greater challenge to sampling accuracy.

[0004] Therefore, how to provide a simple and effective midstream urine sampling device to ensure the accuracy and stability of the sample and reduce the influence of human factors has become an important research direction in the current medical device field. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a mid-stream urine sampling device.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0007] A mid-stream urine sampling device comprises a urinary catheter component, a urine receiving component and a sampling tube, wherein the urinary catheter component comprises an inclined main catheter, the bottom of the main catheter being connected to a first catheter, a second catheter and a third catheter in sequence from high to low, the lower end of the first catheter being movably connected to a lifting sleeve, the bottom of the lifting sleeve being provided with a liquid guide port, the liquid guide port being connected to the third catheter through the liquid guide tube, the lower end of the third catheter being provided with a liquid discharge port leading to a sewage discharge channel, the liquid guide port being further provided with an opening and closing valve, the sampling tube being sleeved with the second catheter, and the urine receiving component being connected to the upper end interface of the main catheter.

[0008] Furthermore, the urine collection assembly includes a flex conduit and a urine collection hopper. The upper end of the flex conduit is connected to the bottom of the urine collection hopper, and the lower end of the flex conduit is movably connected to the upper end of the main conduit. The flex conduit has an L-shaped structure, with the upper end of the flex conduit vertically connected to the urine collection hopper. The lower end of the flex conduit is inserted into the upper end lumen of the main conduit and flexibly connected to the main conduit, with the distal end of the flex conduit extending beyond the corresponding position of the secondary conduit.

[0009] Furthermore, the lower end of the curved conduit is provided with a first through-hole and a second through-hole. The first through-hole is connected to the first conduit, and the second through-hole is connected to the second conduit. Initial urine flows into the first conduit through the first through-hole, and subsequent urine flows into the second conduit through the second through-hole, thereby achieving segmented urine collection.

[0010] Furthermore, a scale is provided on the first catheter, and the static friction between the first catheter and the lifting sleeve is greater than the sliding friction. Different patients have different urine volumes. In order to ensure the collection of mid-stream urine, the amount of front-stream urine can be adjusted. If the patient's urine volume is small, the lifting sleeve is raised to the highest point, thereby reducing the storage volume in the first catheter to ensure the extraction of mid-stream urine. If the patient's urine volume is large, the lifting sleeve is moved downward to increase the storage volume in the first catheter to extract mid-stream urine. In the absence of external force, the lifting sleeve can maintain a stable state. When it is necessary to adjust the capacity of the first catheter, the lifting sleeve is adjusted by external force to meet the regulation needs.

[0011] Furthermore, a fixed base is provided at the bottom of the sampling tube, and a receiving groove for the sampling tube is provided at the center of the top of the fixed base. The fixed base provides stable support for the sampling tube and ensures that the sampling tube is accurately connected to the second conduit to prevent leakage or position deviation.

[0012] Furthermore, the catheter is tilted, directing flow from the first to the third catheter. Gravity allows urine to flow naturally from the first to the third catheter, where it is then discharged through the drainage port. This tilt prevents urine from stagnating and ensures smooth fluid flow. The catheter is a foldable tube, ensuring it remains connected to the third catheter during the vertical adjustment of the lifting sleeve.

[0013] Furthermore, the first, second, and third conduits are vertically connected to the bottom of the main conduit. These vertically arranged conduits allow urine to naturally flow from the bottom of the main conduit into the three conduits, utilizing gravity and the natural flow of fluid to achieve segmented urine diversion. Furthermore, after the first-pass urine enters the first conduit, the middle-pass urine flows over the first conduit without carrying the first-pass urine that has settled to the bottom into the second conduit, thus ensuring the accuracy of the test results.

[0014] Furthermore, the urine collection assembly and sampling tube are both disposable medical supplies. During urine collection, ensuring the sampling tube and urinal are new can prevent any impact on subsequent patient sampling. Furthermore, ensuring the tubing from the urinal to the sampling tube is new can ensure the accuracy of the sampling results.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model utilizes the segmentation of the urinary catheterization component and the principle of gravity to achieve segmented urine automatic diversion, and the patient does not need to hold urine, reducing the difficulty and discomfort of patient sampling;

[0017] 2. The utility model can adjust the amount of urine at the front end according to the individual conditions of the patient (suitable for different urine volumes), making the sampling results more accurate;

[0018] 3. The utility model does not need to be held by hands, which is convenient for patients to perform sampling operations. At the same time, the urine docking component can be replaced without causing mixing effects on subsequent patient sampling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention.

[0024] Example 1

[0025] like Figure 1-3As shown, the utility model discloses a mid-section urine sampling device, including a urinary catheter component, a urine receiving component and a sampling tube 1, the urinary catheter component includes an inclined main catheter 2, the bottom of the main catheter 2 is connected to a first catheter 3, a second catheter 4 and a third catheter 5 in sequence from high to low, the lower end of the first catheter 3 is movably connected to a lifting sleeve 6, the bottom of the lifting sleeve 6 is provided with a liquid guide port, the liquid guide port is communicated with the third catheter 5 through a liquid guide tube 7, the lower end of the third catheter 5 is provided with a liquid discharge port 8 leading to a sewage channel, and an opening and closing valve 9 is also provided on the liquid guide port, the sampling tube 1 is sleeved with the second catheter 4, and the urine receiving component is connected to the upper end interface of the main catheter 2.

[0026] Specifically, the main conduit 2 is used to guide the flow of urine and distribute the urine to the first conduit 3, the second conduit 4 and the third conduit 5 in sequence. The inclined design of the main conduit 2 uses gravity to make the urine flow naturally to the rear end of the main conduit 2. The first conduit 3, the second conduit 4 and the third conduit 5 are used to guide the initial, middle and final urine, respectively. The movable lifting of the lifting sleeve 6 is used to control the volume of the initial urine. During this process, the opening and closing valve 9 remains closed. After the first conduit 3 is full, the urine will flow to the second conduit 4, and after the second conduit 4 is full, the urine will flow to the third conduit 5 and finally be discharged to the drainage port 8.

[0027] The urine collection assembly includes a flexing conduit 10 and a urine collection hopper 11. The upper end of the flexing conduit 10 is connected to the bottom of the urine collection hopper 11, and the lower end of the flexing conduit 10 is movably connected to the upper end of the main conduit 2. Specifically, the flexing conduit 10 has an L-shaped structure, with the upper end of the flexing conduit 10 vertically connected to the urine collection hopper 11. The lower end of the flexing conduit 10 is inserted into the upper end lumen of the main conduit 2, flexibly connecting with the main conduit 2, and the distal end of the flexing conduit 10 extends beyond the corresponding position of the secondary conduit 4.

[0028] The lower bottom surface of the curved conduit 10 is provided with a first through-hole 12 and a second through-hole 13. The first through-hole 12 is connected to the first conduit 3, and the second through-hole 13 is connected to the second conduit 4. Specifically, the initial urine flows into the first conduit 3 through the first through-hole 12, and the subsequent urine flows into the second conduit 4 through the second through-hole 13, thereby achieving segmented urine collection.

[0029] A scale 14 is provided on the first catheter 3, and the static friction between the first catheter 3 and the lifting sleeve 6 is greater than the sliding friction. Specifically, different patients have different urine volumes. In order to ensure the collection of mid-stream urine, the amount of front-stream urine can be adjusted. If the patient's urine volume is small, the lifting sleeve 6 is raised to the highest point, thereby reducing the storage volume in the first catheter 3 to ensure the extraction of mid-stream urine. If the patient's urine volume is large, the lifting sleeve 6 is moved downward to increase the storage volume in the first catheter 3, thereby extracting mid-stream urine. In the absence of external force, the lifting sleeve 6 can maintain a stable state. When it is necessary to adjust the capacity of the first catheter 3, the lifting sleeve 6 is adjusted by external force to meet the regulation needs.

[0030] The bottom of the sampling tube 1 is also provided with a fixed base 15, and the top center of the fixed base 15 is provided with a receiving groove for placing the sampling tube 1. Specifically, the fixed base 15 provides stable support for the sampling tube 1 and ensures that the sampling tube 1 is accurately connected to the second conduit 4 to prevent leakage or position deviation.

[0031] The catheter 7 is tilted, directing urine from the first conduit 3 to the third conduit 5. Specifically, gravity allows urine to flow naturally from the first conduit 3 to the third conduit 5, where it is then discharged through the drainage port 8. This tilted configuration prevents urine stagnation and ensures smooth fluid flow. Furthermore, the catheter 7 is a foldable tube, ensuring it remains connected to the third conduit 5 during the vertical adjustment of the lifting sleeve 6.

[0032] The first, second, and third conduits 3, 4, and 5 are vertically connected to the bottom of the main conduit 2. Specifically, the vertically arranged conduits allow urine to flow naturally from the bottom of the main conduit 2 into the three conduits, utilizing gravity and the natural flow of fluid to achieve segmented urine diversion. Furthermore, after the first-pass urine enters the first conduit 3, the middle-pass urine flows over the first conduit 3 without carrying the first-pass urine that has settled to the bottom into the second conduit 4, thus ensuring the accuracy of the test results.

[0033] The urine collection assembly and sampling tube 1 are both disposable medical supplies. Specifically, during urine collection, ensuring that the sampling tube 1 and urine collection hopper 11 are new medical supplies can avoid impacting subsequent patient sampling. Furthermore, ensuring that the urine pipeline from the urine collection hopper 11 to the sampling tube 1 is new can ensure the accuracy of the sampling results.

[0034] Example 2

[0035] Based on the first embodiment, this embodiment proposes a specific implementation process of a midstream urine sampling device.

[0036] The specific implementation principle process is as follows:

[0037] Insert the sampling tube 1 into the receiving slot in the fixed base 15 and ensure it is secure. Next, use a new urine collection assembly and insert the lower end of the curved catheter 10 into the upper end of the main catheter 2, ensuring that it is flexibly connected to the main catheter 2. Adjust the position of the lifting sleeve 6 according to the patient's expected urine volume. If the urine volume is low, raise the lifting sleeve 6 to its highest position to reduce the storage capacity of the first catheter 3. If the urine volume is high, move the lifting sleeve 6 downward to increase the storage capacity of the first catheter 3. During this process, keep the opening and closing valve 9 closed.

[0038] The patient starts to urinate, and the urine first flows into the curved catheter 10 through the urine receiving hopper 11, and then flows into the first catheter 3 through the first through hole 12 of the curved catheter 10. When the first catheter 3 reaches the predetermined capacity, the urine flows from the main catheter 2 into the second catheter 4. When the second catheter 4 is full, the urine continues to flow into the third catheter 5, and the subsequent urine is discharged from the drainage port 8. After the collection of the middle urine is completed, the sampling tube 1 is removed, sealed and stored, and prepared for inspection. In addition, the opening and closing valve 9 needs to be opened to guide the urine in the first catheter 3 through the drainage tube 7 to the drainage port 8 and discharge it. Thereafter, the urine receiving assembly is removed and discarded to complete the entire process of the sampling operation.

[0039] The present application scheme realizes the automatic collection of mid-stream urine without the need for electricity or complex control systems. The process emphasizes the use of gravity and fluid mechanics principles to divert urine in sections, and adjusts the lifting sleeve 6 to adapt to the urine volume of different patients.

[0040] Of course, the present invention may have many other implementation methods. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims attached to the present invention.
