Description

Technical Field

[0001] The utility model relates to the technical field of sampling equipment for nephrology department, and particularly relates to a urinary catheter sampling device for nephrology department. Background Technique

[0002] Urine sampling plays an important role in the nephrology department. The experimental results after sampling can reflect the status of kidney function. By detecting components such as urinary protein, red blood cells, and white blood cells, it helps to diagnose diseases such as nephritis and nephrotic syndrome. It can also evaluate the filtration and reabsorption ability of the kidneys, understand the excretion of metabolic wastes, and is crucial for monitoring the efficacy of drugs and tracking the changes in the condition. It is a commonly used and effective auxiliary examination method in the nephrology department.

[0003] In the prior art, when sampling a patient's urine, it is necessary to intercept the midstream urine. Since the front-section urine may be contaminated by bacteria, secretions, etc. around the urethral orifice, affecting the accuracy of the test results, and the back-section urine may have conditions such as urine concentration and changes in cell components due to a long stay in the bladder, which will also affect the experimental results. When the patient has the urge to urinate and urinates, it is difficult to control the urine from stopping discharging at any time. After intercepting the midstream urine, it is necessary to immediately remove the sampling device to avoid deviation of the experimental results. Therefore, the patient's urine is likely to pour on the surface of the sampling device when the sampling device is removed, making the subsequent cleaning process more difficult.

[0016] Embodiment: Please refer to Figure 1 - Figure 4 , the present utility model provides a technical solution: a urinary catheter sampling device for nephrology, including: a connecting device 1; a metering tube 2, the outer wall of the metering tube 2 is threadedly connected to the inner wall of the bottom of the connecting device 1; a positioning device 3, the bottom of the positioning device 3 is fixedly connected to the top of the connecting device 1; a pressing device 4, the pressing device 4, the outer wall of the pressing device 4 is slidably connected to the inner wall of the positioning device 3; the connecting device 1 includes a sliding cylinder 11, a funnel 12 is fixedly connected to the inner wall of the sliding cylinder 11, an anti-drip plate 13 is fixedly connected to one end of the funnel 12 away from the sliding cylinder 11, a guiding tube 14 is arranged outside the anti-drip plate 13. Before preparing to collect urine, the pressing column 41 on the positioning device 3 needs to be pressed into the sliding cylinder 11 after holding the connecting device 1 until the pressing column 41 is blocked by the anti-falling ring 111. When urine is discharged, the discharged urine is received by the funnel 12, and the anti-drip plate 13 prevents urine from dripping. Due to the gravity of the urine and the shape of the funnel 12, the urine passes through the position of the communicating groove 44 of the pressing column 41. At this time, the urine flows through the communicating groove 44 to the position of the guiding tube 14 and is discharged from the guiding tube 14.

[0017] A fall-prevention ring 111 is fixedly connected to the inner side wall of the sliding cylinder 11. A drainage ring 112 is arranged at the bottom of the fall-prevention ring 111. An inclined surface groove 113 is formed in the outer wall of the drainage ring 112. The inner wall of the sliding cylinder 11 is threadedly connected to the outer wall of the top of the metering tube 2 through a thread groove 114, and the thread groove 114 is formed in the wall of the sliding cylinder 11. The outer side wall of the outside of the drainage ring 112 is fixedly connected to the inner side wall of the sliding cylinder 11. The bottom of the drainage ring 112 is in contact with the top of the metering tube 2. The positioning device 3 includes a positioning cylinder 31. A sliding hole 32 is formed in the wall of the positioning cylinder 31. The bottom of the positioning cylinder 31 is fixedly connected to the top of the sliding cylinder 11. After the urine in the current section is discharged, the extrusion on the pressing column 41 is released. In the previous pressing stage, due to the downward sliding of the pressing column 41, the tension spring 43 in the moving groove 42 is stretched. Therefore, at this time, the stretched tension spring 43 returns to the non-stretched state before, and will drive the pressing column 41 to slide and lift along the sliding hole 32 of the positioning cylinder 31. At this time, the guiding groove 45 at the bottom of the pressing column 41 is located at the outlet position of the funnel 12, and the urine entering is sent into the metering tube 2 through the conical hole 46.

[0018] The pressing device 4 includes a pressing column 41. A tension spring 43 is fixedly connected to the bottom of the inner wall of the pressing column 41 through a moving groove 42, and the moving groove 42 is formed in the wall of the pressing column 41. A communication groove 44 is formed in the outer wall of the middle part of the pressing column 41. A guiding groove 45 is formed in the outer wall of the pressing column 41 near the bottom end. A conical hole 46 is formed in the bottom of the pressing column 41. The side wall of the pressing column 41 is slidably connected to the inner wall of the positioning cylinder 31 through a sliding hole 32. The side wall of the pressing column 41 is slidably connected to the inner side wall of the sliding cylinder 11. The top end of the tension spring 43 is fixedly connected to the outer wall of the positioning cylinder 31. The pressing device 4 controls the urine to enter the inside of the metering tube 2. When the pressing device 4 is pressed, the urine enters the inside of the sliding cylinder 11 through the funnel 12, flows through the communication groove 44, then flows to the position of the guiding pipe 14, and is discharged after passing through the inside of the sampling device. After the pressing device 4 is released, urine sampling is carried out. The urine is accumulated through the guiding groove 45 and discharged from the conical hole 46. The top opening of the conical hole 46 is large and the bottom opening is small. At the same time, a guiding groove with a radian is arranged at the conical surface position of the conical hole 46, so that the urine rotates and is discharged during the process of entering the metering tube 2.

[0019] Working principle:

[0020] When in use, before the patient urinates, the sampling device is placed at the urethral orifice. Before preparing to collect urine, after holding the connecting device 1, the pressing column 41 on the positioning device 3 is pressed into the sliding cylinder 11 until the pressing column 41 is blocked by the anti-falling ring 111. When urine is discharged, the discharged urine is received through the funnel 12, and the anti-drip plate 13 prevents urine from dripping. Due to the gravity of the urine and the shape setting of the funnel 12, the urine passes through the communication groove 44 position of the pressing column 41. At this time, the urine flows through the communication groove 44 to reach the position of the guiding tube 14 and is discharged from the guiding tube 14. After the front-section urine is discharged, the extrusion of the pressing column 41 is released. In the previous pressing stage, due to the downward sliding of the pressing column 41, the tension spring 43 in the moving groove 42 is stretched. Therefore, at this time, the stretched tension spring 43 returns to its non-stretched state and drives the pressing column 41 to slide and lift along the sliding hole 32 of the positioning cylinder 31. At this time, the guiding groove 45 at the bottom of the pressing column 41 is located at the outlet of the funnel 12, and the urine entering is sent into the metering tube 2 through the tapered hole 46. Before the rear-section urine arrives, it is the same as the front-section urine, and the pressing column 41 can be pressed. Since the operation steps are simple, it can be given to the patient for self-use. The patient can control the intercepted urine according to their own situation. While the middle section of the urine is intercepted by this sampling device, it also makes it difficult for the urine to pour on the surface of the sampling device, resulting in fewer positions of the sampling device that need to be cleaned, and also avoiding the urine on the surface of the sampling device from dripping on the ground.

[0021] A pressing device 4 is provided to control the urine to enter the inside of the metering tube 2. When the pressing device 4 is pressed, the urine enters the inside of the sliding cylinder 11 through the funnel 12, then flows through the communication groove 44, and then flows to the position of the guiding tube 14 and is discharged after passing through the inside of the sampling device. After the pressing device 4 is released, urine sampling is carried out. The urine accumulates through the guiding groove 45 and is discharged from the tapered hole 46. The top opening of the tapered hole 46 is large and the bottom opening is small. At the same time, a guiding groove with a curvature is provided at the conical surface position of the tapered hole 46, so that the urine rotates and drains into the metering tube 2 during the process of entering the metering tube 2, making the urine concentrated and entering from the middle of the metering tube 2. At the same time, a drainage ring 112 is provided to block the position of the threaded groove 114 through the inclined surface groove 113, so that it is difficult for the urine to be taken out through the threaded groove 114 after the metering tube 2 is disassembled. Moreover, when the rotating urine flows, the resistance can be reduced, making the urine flow out more evenly and stably, reducing pressure fluctuations and turbulence effects, and thus reducing noise and vibration and alleviating the patient's embarrassing mood.
