Description

Technical Field

[0001] This disclosure relates to the field of medical device technology, and more particularly to a male urine bag. Background Technology

[0002] For patients with urinary incontinence, a urine bag is required to collect urine and maintain hygiene. Because the urine bag needs to hold urine, it is usually disposable for hygiene reasons.

[0003] In related technologies, male urine bags need to be kept relatively fixed to the male genitals. However, due to the cost requirements of disposable urine bags, the structure of male urine bags is usually relatively simple, and the fixation effect is poor relative to the male genitals. The structures with better fixation effects in related patents have the problem of high cost, making them unsuitable for disposable use and lacking practicality. Utility Model Content

[0004] This disclosure provides a male urine bag to address the problem that male urine bags in the related art cannot simultaneously satisfy both low cost and good fixation effect.

[0005] In a first aspect, embodiments of this disclosure provide a male urine bag, the male urine bag comprising:

[0006] The flexible bag includes an inlet tube, the outer end of which is a urine inlet. An adhesive patch is provided on one side of the outer edge of the urine inlet, and the two ends of the adhesive patch that are off-center from the outer edge of the urine inlet are provided with mutually cooperating adhesive parts.

[0007] The end of the inlet tube that is away from the urine inlet is connected to the drainage tube. The drainage tube extends along the side wall of the flexible bag to the side of the flexible bag that is away from the inlet tube. The end of the drainage tube that is away from the inlet tube is equipped with a one-way anti-backflow structure.

[0008] Optionally, the adhesive patch is a stretchable strip structure with ventilation holes.

[0009] Optionally, the guide tube has a spirally expanding structure along the side wall of the flexible bag, and the diameter of the end of the guide tube adjacent to the inlet tube is smaller than that of the end deviating from the inlet tube.

[0010] Optionally, the one-way anti-backflow structure is an elastic umbrella-shaped valve plate, which includes a fixed rod, a support rod, and an elastic plate. The two ends of the fixed rod are respectively connected to the positions adjacent to the inner sidewall of the guide tube, the support rod is connected to the middle of the fixed rod, and the outer edge of the elastic plate abuts against the lower edge of the guide tube.

[0011] Optionally, the one-way anti-backflow structure is an elastic elliptical valve plate. The elliptical valve plate includes a fixed part and a movable part. The fixed part is fixedly connected to the inner sidewall of the guide tube near the end. The movable part is inclined relative to the axis of the guide tube. The projection shape of the movable part along the direction perpendicular to the axis is the same as the cross-sectional shape of the guide tube. The edges of the movable part are respectively connected to the sidewall of the guide tube. The end of the movable part that is away from the fixed part abuts against the end of the guide tube.

[0012] Optionally, the flexible bag body is provided with at least two symmetrically distributed fixing ears, and the fixing ears are provided with waist belt perforations.

[0013] Optionally, the adhesive patch surface is covered with release paper, which has pre-cut tear strips.

[0014] Optionally, the flexible bag body adopts a two-layer composite structure, with an inner layer of hydrophobic polyethylene and an outer layer of non-woven fabric.

[0015] Optionally, the inner wall of the inlet pipe is provided with a corrugated anti-slip texture.

[0016] Optionally, the flexible bag has a volume of 300ml to 500ml, and the surface of the flexible bag is provided with capacity graduation lines.

[0017] The male urine bag provided in this disclosure achieves effective fixation of the male genitalia by setting an adhesive patch on one side of the urine inlet and having mutually cooperating adhesive parts at both ends of the adhesive patch, thereby enhancing the stability of the urine bag and solving the problem of poor fixation in the prior art. At the same time, the use of a flexible bag body and a simple one-way anti-backflow structure reduces production costs, allowing the urine bag to be used as a disposable product, meeting the requirement of low cost. Furthermore, the one-way anti-backflow structure prevents urine from flowing back and overflowing, thus ensuring both fixation effectiveness and economy and practicality, improving the patient's user experience.

[0028] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0029] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0030] The technical solutions of this disclosure and how they solve the aforementioned technical problems will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0031] In the field of medical devices, especially in urinary incontinence care products, the design of male urine bags has always faced a trade-off between cost and functionality. Patients with urinary incontinence need to wear urine bags to collect urine and ensure hygiene. However, because urine bags need to hold urine and are usually for single use, the design must balance cost and functionality.

[0032] In existing technologies, male urine bags need to be kept relatively fixed to the male genitalia to prevent urine leakage and bag displacement. However, due to cost limitations of disposable urine bags, a relatively simple structure is usually adopted, resulting in poor fixation and easy leakage or discomfort during use. On the other hand, although some patented technologies provide structures with better fixation, their complexity and high cost prevent them from being used as disposable products, limiting their practicality and popularity in the market.

[0033] The difficulty in improving this issue lies in the need for a deep understanding of the various mechanical and ergonomic factors involved in the actual use of urine bags. This is because urine bags not only need to remain stable when worn, but also need to adapt to changes in body shape and activity level during use, further increasing the complexity of the design. This has resulted in a lack of effective urine bag solutions in related technologies that meet both cost and functional requirements.

[0034] To address this issue, this disclosure provides a male urine bag. By attaching an adhesive patch to one side of the urine inlet and having mating adhesive portions at both ends of the patch, effective fixation of the male genitalia is achieved, enhancing the stability of the urine bag. Furthermore, the design employs a flexible bag body and a one-way anti-backflow structure to ensure safe urine flow and prevent backflow contamination. This improves the fixation effect while maintaining low cost, making the urine bag suitable for single use and enhancing the patient experience.

[0035] The application scenarios of the embodiments of this disclosure are explained below:

[0036] Figure 1 This is a schematic diagram of a prior art male urine bag provided as an embodiment of this disclosure. Figure 1 As shown, to save costs, the existing urine bag 100 is usually a plastic bag with a knot 110 tied and then put on the male genitals to collect urine.

[0037] It should be noted that, Figure 1 The scenario shown is illustrated using only one urine bag and one knot as an example, but this disclosure is not limited to this; that is, the number of urine bags and knots can be arbitrary.

[0038] The following detailed description of the male urine bag provided in this disclosure is provided through specific embodiments.

[0039] Figure 2This is a schematic diagram of a male urine bag provided in one embodiment of the present disclosure. Figure 3 for Figure 2 The diagram shows the external structure of a male urine bag. (Combined with...) Figure 2 and Figure 3 As shown, the male urine bag 200 provided in this embodiment includes:

[0040] The flexible bag 210 includes an inlet tube 220. The outer end of the inlet tube 220 is a urine inlet 221. An adhesive patch 230 is provided on one side of the outer edge of the urine inlet 221. The two ends of the adhesive patch 230 that are offset from the outer edge of the urine inlet 221 are provided with mutually cooperating adhesive portions 231.

[0041] One end of the inlet tube 220, which is away from the urine inlet 221, is connected to the guide tube 240. The guide tube 240 extends along the side wall of the flexible bag 210 to the side of the flexible bag 210 away from the inlet tube 220. The guide tube 240 and the end of the inlet tube 220 away from the inlet tube 220 are provided with a one-way anti-backflow structure 250.

[0042] Specifically, this embodiment mainly provides a general description of the main structure of the male urine bag 200 provided in this solution.

[0043] The flexible bag 210 is the main body of the entire urine bag, used to contain urine. It is typically made of medical-grade plastic or rubber, possessing good flexibility and sealing properties to ensure no leakage occurs during use.

[0044] Optionally, the flexible bag 210 can be designed in multiple different sizes to meet the needs of patients of different body types and provide a comfortable experience when worn, depending on the age and body type of the male patient.

[0045] An inlet tube 220 is connected to one end of the flexible bag body 210, with its outer end serving as a urine inlet 221. The inlet tube 220 is designed to ensure smooth urine flow into the bag body, and its size and shape are optimized for easy connection with the male genitalia. The inlet tube 220 is typically made of the same material as the flexible bag body 210 to ensure overall sealing and durability.

[0046] The adhesive patch 230 is disposed on one side of the outer edge of the urine inlet 221. On the one hand, it can provide additional fixation support, and on the other hand, it can seal the urine inlet 221 to prevent urine from flowing back out of the urine inlet 221.

[0047] The adhesive patch 230 is made of medical-grade adhesive material and can adhere firmly to the skin. The two ends of the adhesive patch 230 are provided with interlocking adhesive portions 231, which can be adjusted as needed to adapt to the physiological characteristics of different patients, thereby providing a personalized fixation effect.

[0048] The drainage tube 240 is connected to the end of the inlet tube 220 that is offset from the urine inlet 221, and extends along the side wall of the flexible bag body 210 to the side of the bag body that is offset from the inlet tube 220. The design of the drainage tube 240 ensures that urine can flow quickly and safely into the bottom of the bag body, preventing urine from accumulating at the inlet in the bag body, thereby reducing the risk of backflow.

[0049] A one-way anti-backflow structure 250 is located at the end of the guide tube 240 away from the inlet tube 220. Its function is to prevent urine from flowing back into the inlet tube 220. This structure typically employs a one-way valve design, allowing urine to flow in one direction, ensuring that urine inside the bag does not flow back, and maintaining patient hygiene and comfort.

[0050] Thus, the connection between the inlet tube 220 and the flexible bag body 210 provides an inlet channel for urine, while the design of the adhesive patch 230 enhances the fixation of the urine bag to the genitals. The extended design of the drainage tube 240 ensures that urine can be quickly introduced into the bottom of the bag body, and together with the one-way anti-backflow structure 250, effectively prevents urine backflow. The synergistic effect of these structures allows the urine bag to remain stable during use while effectively preventing leakage.

[0051] Therefore, in practical applications, this structure only requires connecting the inlet tube 220 to the patient's genitals, and then using the adhesive portion 231 of the adhesive patch 230 to bond the connection between the inlet tube 220 and the patient's genitals, thus securing the male urine bag 200 to the patient's genitals. This process is simple to operate and, compared to existing solutions using plastic bags as urine bags, better ensures the fixation of the male urine bag 200. Furthermore, the adhesive portion 231 of the adhesive patch 230 prevents urine from leaking out of the male urine bag 200.

[0052] When it is necessary to remove the male urine bag 200, simply peel off the adhesive part 231 to remove it. Then, fold the adhesive patch 230 towards the inlet tube 220, and use the adhesive part 231 to fix the adhesive patch 230 to the outer wall of the inlet tube 220. This achieves a seal on the male urine bag 200, preventing urine spillage, facilitating use, and improving hygiene.

[0053] The male urine bag provided in this disclosure achieves effective fixation of the male genitalia by setting an adhesive patch on one side of the urine inlet and having mutually cooperating adhesive parts at both ends of the adhesive patch, thereby enhancing the stability of the urine bag and solving the problem of poor fixation in the prior art. At the same time, the use of a flexible bag body and a simple one-way anti-backflow structure reduces production costs, allowing the urine bag to be used as a disposable product, meeting the requirement of low cost. Furthermore, the one-way anti-backflow structure prevents urine from flowing back and overflowing, thus ensuring both fixation effectiveness and economy and practicality, improving the patient's user experience.

[0054] Figure 4 This is a schematic diagram of the structure of a male urine bag provided in another embodiment of this disclosure. Figure 5 and Figure 6 These are schematic diagrams of one type of unidirectional anti-backflow structure, combined with... Figures 4 to 6 As shown, in Figure 2 and Figure 3 Based on the illustrated embodiment, the male urine bag provided in this embodiment further includes:

[0055] The adhesive patch 230 is a strip-shaped structure with elasticity, and the adhesive patch 230 has ventilation holes 232.

[0056] Specifically, by designing the adhesive patch 230 as a stretchable strip structure, this design allows the adhesive patch 230 to better adapt to the physiological curves of different patients, providing a more fitting fixation effect.

[0057] Multiple ventilation holes 232 can be arrayed on the adhesive patch 230 to improve wearing comfort and reduce skin discomfort or allergies that may occur from prolonged wear.

[0058] The elasticity of the adhesive patch 230 and the design of the vent 232, combined with the urine inlet 221 and the flexible bag body 210, ensure good breathability and comfort while maintaining a secure fit.

[0059] In some embodiments of this disclosure, the guide tube 240 has a spirally expanding structure along the side wall of the flexible bag 210, and the diameter of the end of the guide tube 240 adjacent to the inlet tube 220 is smaller than that of the end deviating from the inlet tube 220.

[0060] Specifically, by designing the drainage tube 240 as a spirally expanding structure along the side wall of the flexible bag 210, the flow path of urine is increased, the drainage efficiency is improved, and the urine can flow smoothly into the bottom of the bag, reducing the risk of backflow.

[0061] The front end of the drainage tube 240 (the end adjacent to the urine inlet 221) is directly connected to the rear end of the inlet tube 220 (the end away from the urine inlet 221) (or they can be the same integral part; the different names here are just for easy distinction of their functions), and extends along the side wall of the flexible bag 210. The spiral expanding design does not affect its connection with the flexible bag 210, but provides a more effective urine drainage path.

[0062] The spiral expansion design increases the flow path of urine, improves the diversion efficiency, ensures that urine can be quickly diverted to the bottom of the bag, and reduces the possibility of backflow.

[0063] In some embodiments of this disclosure, the one-way anti-backflow structure 250 is an elastic umbrella-shaped valve plate, which includes a fixed rod 251, a support rod 252 and an elastic plate 253. The two ends of the fixed rod 251 are respectively connected to the positions near the end of the inner sidewall of the guide tube 240, the support rod 252 is connected to the middle part of the fixed rod 251, and the outer edge of the elastic plate 253 abuts against the lower edge of the guide tube 240.

[0064] Specifically, such as Figure 5 As shown, in one alternative embodiment, the unidirectional anti-backflow structure 250 employs an umbrella-shaped valve design, which consists of a fixed rod 251, a support rod 252, and an elastic plate 253. The two ends of the fixed rod 251 are respectively connected to the adjacent ends of the inner wall of the guide tube 240, ensuring the stability of the valve and ensuring that the valve can open when urine flows and close when backflow occurs, thereby ensuring unidirectional urine flow and preventing backflow.

[0065] Optionally, the material and size of the umbrella-shaped valve can be adjusted according to specific needs to accommodate different urine flow rates and bag capacities.

[0066] In some embodiments of this disclosure, such as Figure 6 As shown, the one-way anti-backflow structure 250 is an elastic elliptical valve plate. The elliptical valve plate includes a fixed part 254 and a movable part 255. The fixed part 254 is fixedly connected to the inner side wall of the guide tube 240 near the end. The movable part 255 is inclined relative to the axial direction of the guide tube 240. The projection shape of the movable part 255 along the direction perpendicular to the axial direction is the same as the cross-sectional shape of the guide tube 240. The edges of the movable part 255 are respectively connected to the side wall of the guide tube 240. The end of the movable part 255 that is away from the fixed part 254 abuts against the end of the guide tube 240.

[0067] Specifically, such as Figure 4As shown, this is a schematic diagram of another unidirectional anti-backflow structure. In another embodiment, the unidirectional anti-backflow structure 250 can also adopt an elliptical valve plate design, which consists of a fixed part 254 and a movable part 255. The fixed part 254 is fixedly connected to the adjacent end of the inner wall of the guide pipe 240 to ensure the stability of the valve plate.

[0068] By connecting the fixing part 254 to the inner wall of the guide tube 240 and setting the movable piece 255 at an angle relative to the axial direction of the guide tube 240, it is ensured that the movable piece 255 can open when urine flows and close when backflow occurs, thereby ensuring that urine can flow in one direction and preventing backflow.

[0069] In some embodiments of this disclosure, at least two symmetrically distributed fixing ears 211 are provided on the outer side of the flexible bag body 210, and the fixing ears 211 are provided with waist belt perforations 212.

[0070] Specifically, in combination Figure 4 As shown, when the urine volume of the male urine bag 200 is large, the weight of the flexible bag body 210 is large, and the adhesive patch 230 alone cannot guarantee its reliability of fixation. Therefore, symmetrically distributed fixing ears 211 can be set on the outside of the flexible bag body 210. The fixing ears 211 are provided with waist belt perforations 212, which are connected to the external waist belt through the waist belt perforations 212 to provide additional fixation support, reduce the possibility of the urine bag shifting due to weight, and ensure that the urine bag can be firmly fixed to the patient's body.

[0071] In some embodiments of this disclosure, the surface of the adhesive patch 230 is covered with release paper 233, and the release paper 233 is provided with pre-cut tear strips 234.

[0072] Specifically, in combination Figure 4 As shown, by setting release paper 233 (the adhesive patch 230 in the figure is only for illustrative purposes and should not actually be visible), this design allows the adhesive patch 230 to be kept clean before use, thereby ensuring the hygiene and cleanliness of the parts in contact with the adhesive patch 230. In addition, the tear strip design makes it convenient for patients to quickly peel off the release paper 233.

[0073] Before the male urine bag 200 is used, the release paper 233 is attached to the adhesive patch 230 to ensure that the adhesive patch 230 is clean before use. When using, the patient can quickly peel off the release paper 233 through the pre-cut tear strip 234 for convenient use.

[0074] In some embodiments of this disclosure, the flexible bag 210 adopts a two-layer composite structure, with an inner layer of hydrophobic polyethylene and an outer layer of non-woven fabric.

[0075] Specifically, in combination Figure 3As shown, in order to prevent the male urine bag 200 from absorbing water and leaking during use, and to improve the comfort of the outer layer of the flexible bag body 210 that comes into contact with the skin, the flexible bag body 210 can be set as a composite structure of a hydrophobic polyethylene layer and a non-woven fabric layer, thereby providing better waterproofness and comfort.

[0076] Alternatively, the two-layer composite structure can be bonded together using adhesive or hot-pressing processes to ensure the integrity and functionality of the bag.

[0077] Optionally, the materials and thickness of the two-layer composite structure can be adjusted according to specific needs to improve waterproofing and comfort; no restrictions are imposed here.

[0078] In some embodiments of this disclosure, the inner wall of the inlet pipe 220 is provided with a wavy anti-slip texture 222.

[0079] Specifically, the inner wall of the inlet tube 220 is provided with a wavy anti-slip texture 222, which achieves a better fixation effect on the male genitals and ensures that urine can flow smoothly into the bag. The wavy anti-slip texture 222 can also enhance the extensibility of the inlet tube 220 and prevent it from wrinkling, thereby reducing the possibility of blockage.

[0080] In some embodiments of this disclosure, the flexible bag 210 has a volume of 300ml to 500ml, and the surface of the flexible bag 210 is provided with capacity scale lines 213.

[0081] Specifically, in combination Figure 3 As shown, by setting volume scale lines 213 on the surface of the bag, a volume monitoring function is provided, which makes it convenient for patients to understand the urine collection status and to replace it in a timely manner.

[0082] By controlling the volume of the flexible urine bag 210, the needs of male patients for a single urination are met, while avoiding an excessively large flexible urine bag 210 that would lead to infrequent replacement (or waste of most of its volume), thus increasing the risk of infection. This improves the convenience and safety of using the urine bag.

[0083] Through the various structures in this embodiment, based on the aforementioned embodiments, the use of the male urine bag 200 requires no additional operations. Furthermore, the ventilation holes 232 improve the comfort of the connection between the genitals and the adhesive patch 230. The drainage tube 240 ensures that the patient's urine reaches only the bottom of the bag, reducing the risk of backflow and preventing urine from overflowing from the male urine bag 200. The one-way anti-backflow structure 250 increases the difficulty of urine flowing back into the inlet tube 220, further preventing urine from overflowing from the male urine bag 200. The fixing ear 211 allows for easy access when the patient urinates. If the urine volume is large, or if the male urine bag 200 has a large volume, the male urine bag 200 can be fixed to the patient's waist belt through the fixing ear 211 to prevent the male urine bag 200 from falling off the patient's waist due to gravity when the urine volume is large; by setting the release paper 233, the usability of the adhesive part 231 is ensured; by setting the flexible replacement 210, the comfort of the male urine bag 200 in contact with the skin can be improved; by setting the wavy anti-slip texture 222, the fixing effect of the inlet tube 220 to the genitals is increased; by setting the capacity scale line 213, the observation effect of the urine volume inside the male urine bag 200 is enhanced.

[0084] It should be noted that the various improvements provided in this embodiment may increase the cost of the male urine bag 200, exceeding the price that patients can accept. Therefore, in practice, some of the structures can be selected from the various improvements in this embodiment and added to the structure of the aforementioned embodiment to control the cost of the male urine bag 200 and achieve the optimal balance between cost and ease of use. The specific selection method is not limited here.

[0085] The male urine bag provided in this disclosure improves functionality and patient experience through various structural designs. The elasticity and breathable design of the adhesive patch enhance wearing comfort and fixation; the spiral-expanding drainage tube ensures smooth urine flow to the bottom of the bag, reducing the risk of backflow; umbrella-shaped and elliptical valves provide effective unidirectional flow control to prevent backflow; the fixing ears and waistband perforations increase wearing stability; release paper and tear strips simplify use and keep the adhesive patch clean; the two-layer composite structure improves waterproofing and comfort; the wavy anti-slip texture ensures smooth urine flow; and the capacity scale allows patients to monitor urine collection. These designs collectively enhance the practicality, safety, and comfort of the urine bag, resolving the conflict between fixation effectiveness and cost in existing technologies, and providing a more ideal care solution for patients with urinary incontinence.
