Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a multifunctional medical urine collection bag. Background Technology

[0002] A urine collection bag is a sterile plastic bag used to collect urine from an indwelling catheter. It also allows for easy recording of the volume of urine discharged. In some prostate and bladder surgeries, urine collection bags are also provided to collect any urine that is accidentally discharged during the procedure.

[0003] During surgeries of the reproductive system, such as those involving the prostate, blood and other bodily fluids flow into the ureters, causing a change in the color of the patient's urine. However, existing urine collection bags typically only record the volume of urine collected, not the color of the urine excreted during surgery. This results in poor monitoring of urine status during surgery, which in turn affects the normal progress of the procedure.

[0004] When recording urine volume, some urine bags may accumulate air bubbles due to the presence of air bubbles in the urine. The presence of air bubbles can interfere with the reading of the liquid level scale in the urine bag, which is not conducive to recording the urine volume in the urine bag. The presence of air bubbles can also affect the image analysis of urine images captured by the camera.

[0005] In addition, in a confined and crowded environment, the urine collection bag may be accidentally bumped due to limited space or insufficient light, which may cause the urine to flow back or bend and deform, affecting the collection and reading of urine storage capacity.

[0006] Therefore, providing a multifunctional medical urine collection bag that can monitor urine color to analyze patient conditions, avoid air bubble interference, improve the stability and reliability of the urine collection bag in complex environments, and avoid various adverse consequences caused by collisions is a technical problem that urgently needs to be solved in this field.

[0032] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0034] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0035] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0036] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0037] In one alternative embodiment, refer to Figures 1-5 The multifunctional medical urine collection bag provided in this embodiment includes a urine bag body 10, a urinary catheter 11 connected to the top end of the urine bag body 10, and a drain pipe 12 connected to the bottom end of the urine bag body 10; a check valve 13 is installed on the urinary catheter 11.

[0038] It also includes a support device, the urine bag body 10 is detachably connected to the support device, the support device is used to support the urine bag body 10 to prevent the urine bag body 10 from deforming and affecting the liquid storage.

[0039] An air bubble elimination device and a detection device are fixed on the urine bag body 10. The air bubble elimination device is used to eliminate air bubbles in the urine bag body 10 by vibration; the detection device is used to detect the color and volume of the liquid stored in the urine bag body 10.

[0040] The bubble elimination device, detection device, and output device are electrically connected to the controller.

[0041] Understandably, the urine bag body 10 is used to store urine, the catheter 11 is responsible for introducing urine from the patient's body into the urine bag body 10, and the drain tube 12 is used to drain the urine collected in the urine bag body 10. A check valve 13 prevents urine from flowing back from the urine bag body 10 to the catheter 11, avoiding urine contamination and bacterial growth, and ensuring patient safety. A support device provides support for the urine bag body 10, preventing deformation, ensuring normal fluid storage, and ensuring accurate measurement. An air bubble elimination device eliminates air bubbles inside the urine bag body 10 through vibration, preventing air bubbles from interfering with urine volume reading and image analysis by the detection device, solving the air bubble interference problem, and improving detection accuracy. The detection device detects urine color and volume, providing urine status information to medical staff to assist in assessing the patient's condition. The controller, as the core control component, coordinates the operation of each device, receives and processes data from the detection device, and controls the operation of the air bubble elimination device. Output device: Presents the test results to medical staff in various forms to facilitate their access to information. For example, the output device can be a display screen that visually shows key information such as urine color, volume, and whether blood or body fluids were detected; or it can be a voice broadcast module that provides voice alerts when abnormalities are detected, allowing medical staff to obtain urine test results promptly and make accurate medical decisions.

[0042] The multifunctional medical urine collection bag consists of a urine bag body 10, a catheter 11, a drain tube 12, a check valve 13, a support device, an air bubble elimination device, a detection device, a controller, and an output device. The catheter 11 connects to the top of the urine bag body 10, the drain tube 12 connects to the bottom, and the check valve 13 is mounted on the catheter 11. The support device is detachably connected to the urine bag body 10, maintaining the shape of the urine bag body 10 and providing a foundation for the stable operation of other devices. The air bubble elimination device and the detection device are fixed to the urine bag body 10. The detection device transmits detection data to the controller, which determines whether to activate the air bubble elimination device based on the data and transmits the processed data to the output device for display. Under the unified coordination of the controller, all devices work together to complete functions such as urine collection, detection, air bubble elimination, and result display, improving the reliability and functionality of the urine collection bag in medical use.

[0043] In one alternative embodiment, refer to Figures 1-5 The support device includes a base 15 and two fixing strips 19 slidably connected to the base 15; the bottom of the urine bag body 10 is placed on the base 15, and the two sides of the urine bag body 10 are inserted into the fixing strips 19. The base 15 is provided with a through hole 16, through which the drain pipe 12 passes; the two sides of the base 15 are provided with sliding grooves 17, and the fixing strips 19 are connected to the sliding grooves 17 through sliders 18.

[0044] Understandably, in environments with limited space and insufficient light, urine collection bags are easily bumped. The base 15 and fixing strip 19 can surround and support the urine bag body 10. When there is an external impact, the support device can withstand part of the impact force, reduce the force directly exerted on the urine bag body 10, prevent it from bending and deforming due to the impact, ensure the accuracy of urine volume collection and reading, avoid problems such as urine backflow, and provide reliable data support for medical staff to judge the patient's condition.

[0045] The base 15 is made of a sturdy yet lightweight material, such as high-strength engineering plastic, without adding extra weight. The bottom of the base 15 has an anti-slip texture, ensuring stability when placed on a bedside table or the floor. The upper surface of the base 15 is designed to be curved or flat to conform to the shape of the bottom of the urine bag body 10, ensuring that the bottom of the urine bag body 10 can rest stably on the base 15, providing stable bottom support. The base 15 has a through-hole 16 through which the drainage tube 12 passes, facilitating drainage operations and preventing bending or blockage of the drainage tube 12 during use. The fixing strip 19 is connected to the sliding groove 17 on the base 15 via a slider 18, allowing for flexible adjustment of the position of the fixing strip 19 according to actual conditions. This securely fixes urine bag bodies 10 of different sizes, ensuring stable operation in various scenarios, unaffected by changes in placement or patient position.

[0046] There are two fixing strips 19, located on both sides of the base 15. They are connected to the sliding grooves 17 on both sides of the base 15 via sliders 18, allowing them to slide flexibly on the base 15 to accommodate urine bag bodies 10 of different sizes. The inner side of the fixing strip 19 has a groove, the opening of which clamps onto the two sides of the urine bag body 10. The groove is designed to fit the sides of the urine bag body 10, for example, using a U-shape or semi-circular arc. The inside of the groove is made of a soft material with a certain degree of friction, such as silicone or rubber, which can both tightly fit the sides of the urine bag body 10 and prevent damage. When the fixing strip 19 is adjusted to the appropriate position by the slider 18, the groove opening clamps firmly hold the two sides of the urine bag body 10, working together with the base 15 to provide all-round support for the urine bag body 10 from the bottom and sides. This effectively prevents the urine bag body 10 from deforming under external impact, compression, or its own weight, ensuring the accuracy of urine storage and measurement, and avoiding urine backflow caused by collisions.

[0047] It should be noted that a corresponding locking structure can be designed as needed. When the slider 18 moves to the appropriate position, the locking structure prevents the slider 18 from moving. For example, a wedge structure can be set between the slider 18 and the sliding groove 17. Specifically, the sliding groove 17 of the base 15 has a slanted groove on its side that matches the wedge, and the slider 18 has a corresponding groove to accommodate the wedge. When the slider 18 moves to the appropriate position, the wedge is inserted between the slanted groove and the groove of the slider 18. Due to the wedge-shaped structure of the wedge, a lateral force is generated after insertion, causing the slider 18 to fit tightly against the sliding groove 17, thus achieving fixation. When the position needs to be adjusted, the wedge can be pulled out. To prevent loss, the wedge is connected to the base 15 by a connecting rope at an appropriate distance.

[0048] It should be noted that, for ease of use, a hanging rope can be installed between the two fixing strips 19 to suspend the urine bag body 10 in a place where it is not easily bumped. When hanging, ensure that the height is appropriate and does not affect urine drainage. Alternatively, a detachable fixing support can be installed at the bottom of the base 15 to stably and steadily place the urine bag body 10 on the ground without affecting the use of the drainage pipe 12, preventing the urine bag body 10 from tilting due to insufficient self-support.

[0049] In one alternative embodiment, refer to Figures 1-5 The bubble elimination device includes a miniature vibration motor 20 and a vibration transmission plate 21 fixed on a support device. The vibration transmission plate 21 abuts against the outer wall of the urine bag body 10.

[0050] Understandably, the bubble elimination device includes a miniature vibration motor 20 and a vibration transmission plate 21 fixed on the support device. The miniature vibration motor 20 is controlled by a controller. When an air bubble is detected inside the urine bag body 10, the controller activates the miniature vibration motor 20. The vibration transmission plate 21 abuts against the outer wall of the urine bag body 10, which not only transmits the high-frequency vibration generated by the miniature vibration motor 20 to the urine bag body 10, causing the air bubble to burst or float to the urine surface, eliminating the interference of air bubbles on liquid level reading and image analysis, but also helps to support the urine bag body 10, buffering the impact force from the surrounding area, further protecting the urine bag body 10, and reducing the damage caused by collisions.

[0051] In one alternative embodiment, refer to Figures 1-5 The detection device includes a solenoid valve 14, which is installed on both the urinary catheter 11 and the drainage tube 12. The solenoid valve 14 is electrically connected to the controller. The detection device also includes a camera 23, which is fixed to the support device by a bracket 24. The camera 23 is used to comprehensively monitor the liquid stored in the urine bag body 10.

[0052] Understandably, the solenoid valve 14 is equipped with a high-precision flow sensor, and the controller, based on the principle of electromagnetic induction, can calculate the instantaneous flow rate of urine. Simultaneously, the controller has a built-in time recording module that records the time intervals of urine flow and, according to the formula "flow rate = flow velocity × time × pipe cross-sectional area," accurately calculates the urine flow rate through the catheter 11 over a period of time, providing medical staff with more precise urine flow data and helping to accurately assess the patient's kidney function and metabolic status. When the urine volume in the urine bag body 10 exceeds the preset capacity, the voice broadcast module of the output device issues a voice reminder as needed, facilitating timely preparation by medical staff after the drainage tube 12 drains. For example, a voice reminder a few minutes before drainage tube 12 drains allows medical staff to place a urine collection bucket at the output end of the drainage tube 12 to collect the drained liquid and avoid soiling the floor. At the same time, the controller controls the solenoid valve 14 on the drainage tube 12 to open, draining the urine from the urine bag body 10 and avoiding frequent changes to the urine bag body 10.

[0053] Camera 23 is fixed to the support device via bracket 24. A high-resolution, low-light industrial-grade camera 23 is selected, with its lens facing the liquid area stored inside the urine bag body 10. After the solenoid valve 14 is activated, camera 23 begins to capture or record images of the liquid inside the urine bag body 10, comprehensively monitoring the liquid stored inside the urine bag body 10. When camera 23 detects air bubbles inside the urine bag body 10, the controller activates the micro vibration motor 20. The vibration transmission plate 21 transmits the high-frequency vibration generated by the micro vibration motor 20 to the urine bag body 10, causing the air bubbles to burst or float to the urine surface, eliminating the interference of air bubbles on liquid level reading and image analysis.

[0054] The captured images are used by the subsequent image analysis module to analyze urine color, the presence of foreign objects (such as blood, body fluids, etc.), and to calculate urine volume by combining urine height in the image with the shape parameters of the urine bag body 10. The controller's image analysis module has powerful image recognition and processing algorithms. After the image captured by camera 23 is transmitted to the image analysis module, the color analysis algorithm is used to accurately identify the urine color. By comparing it with the built-in standard urine color library, it is determined whether the urine color is normal. If an abnormal red color appears, it can be preliminarily determined that blood may be mixed in the urine; if the color is cloudy or has other special colors, it may indicate the presence of body fluids, etc.

[0055] It should be noted that image recognition technology can also be used to analyze the morphology of foreign objects in urine. If special shapes resembling blood cells or other bodily fluid components are detected, it can further confirm the presence of blood or other bodily fluids in the urine. Furthermore, by analyzing the height of urine in the image and combining it with the shape parameters of the urine bag body 10, the urine volume can be calculated, achieving non-contact detection of urine volume.

[0056] In one alternative embodiment, refer to Figures 1-5 The urine bag body 10 is provided with a capacity scale bar 25; the urine bag body 10 is provided with a comparison diagram 22.

[0057] Understandably, the urine bag body 10 features clear volume scale bars 25. These scale bars are printed in a prominent color with uniform spacing, each representing a specific volume value. This allows medical personnel to visually read the approximate volume of urine within the urine bag body 10, serving as an auxiliary means of urine volume detection. This information is cross-referenced with the volume calculations in the testing device, improving the accuracy of volume assessment. The urine bag body 10 also includes a comparison chart 22, which provides image examples of standard color, transparency, and possible impurities in urine under different health conditions. In emergency situations or when precise analysis using a testing device is inconvenient, medical personnel can make a preliminary assessment of the urine's condition by simply comparing the liquid inside the urine bag body 10 with the images in the comparison chart 22, quickly obtaining a general understanding of the patient's urine and providing a reference for further diagnosis.

[0058] Surgical Application: In a prostate surgery, after the patient is positioned, the fixing strip 19 is adjusted according to the size of the urine bag body 10, and the urine bag body 10 is fixed to the base 15. Medical staff connect the catheter 11 of the fixed multifunctional medical urine collection bag to the patient, ensuring that the check valve 13 on the catheter 11 is working properly. Then, the urine collection bag is fixed in a suitable position beside the bed.

[0059] After the surgery began, as urine started flowing into the catheter 11, the solenoid valve 14 activated, and the controller immediately activated the camera 23 to begin recording. The bubble elimination device was also activated as needed. During the surgery, the camera 23 continuously recorded changes in the urine's condition, and the bubble elimination device removed any air bubbles. Medical staff observed the urine's color, flow rate, and volume in real time on the output device's display screen. When the urine turned red, based on the image analysis module's assessment, the presence of blood was initially suspected. This was promptly communicated to the surgeon, who adjusted the surgical procedure accordingly, ensuring the surgery's success.

[0060] Application in routine nursing care: In a general ward, a patient with a long-term indwelling urinary catheter 11 uses a multifunctional medical urine collection bag for urine collection. Nurses regularly check the collection bag daily, using the volume scale 25 to initially assess urine volume and color changes. However, regular checks cannot provide timely updates on the patient's health. Therefore, when the detection device detects potentially abnormal fluids in the urine, the output device issues a voice prompt. Medical staff can further confirm the urine status by comparing it with the comparison chart 22 on the urine bag itself or by viewing the information displayed on the output device's screen. Upon discovering an abnormality, medical staff can promptly conduct further examinations and diagnoses, saving valuable time for the patient's treatment.

[0061] This multifunctional medical urine collection bag has the following beneficial effects:

[0062] Safety is ensured by the check valve 13, which effectively prevents urine backflow and protects patient safety.

[0063] Stable support: The support device is adjustable and stable, preventing the urine bag body 10 from deforming due to collision, ensuring accurate urine storage and measurement, and adapting to urine collection bags of different capacities.

[0064] Bubble elimination: The bubble elimination device can not only eliminate bubble interference, but also assist in supporting the urine bag body 10, improve detection accuracy, and reduce collision damage.

[0065] Precise detection: The detection device utilizes solenoid valve 14, camera 23 and image analysis module to achieve comprehensive detection of urine flow, color, presence of blood and body fluids, and urine volume, providing a strong basis for disease diagnosis.

[0066] Convenient Auxiliary Features: The volume scale bar 25 and comparison chart 22 provide medical staff with an intuitive and convenient way to judge the state of urine. As an auxiliary means, they work together with the detection device to further improve the accuracy and timeliness of urine monitoring.

[0067] Convenient feedback: The output device provides timely feedback on test results in various forms, making it convenient for medical staff to obtain information and improving medical efficiency.
