Description

Technical Field

[0001] This utility model relates to the field of medical and health products technology, and in particular to a urine bag. Background Technology

[0002] Traditional urine bags consist of a bag body, which is mostly made of plastic film. The manufacturing process mainly includes: folding the plastic film in half, then using a high-temperature heat-sealing device to heat-seal the folded edges and die-cutting it, thereby forming a bag structure with an open top and sealed edges.

[0003] However, this traditional structure has significant technical drawbacks in practical medical applications: First, the bag body, made of a plastic film, lacks sufficient strength and is prone to puncture and damage when in contact with sharp objects such as catheter connectors or surgical instruments; second, the heat-sealing process results in a weak structure at the heat-sealed edge, with significant material stress concentration in this area. This sealed area is also susceptible to frequent friction and abrasion from the outside, easily leading to cracks and leakage. Therefore, there is an urgent need to design a urine bag that combines protection and abrasion resistance. Utility Model Content

[0004] The technical problem to be solved by this utility model embodiment is to provide a urine bag to solve the problem that the urine bag itself is not strong enough and is easily scratched and damaged in the prior art.

[0005] The urine bag provided in this embodiment of the utility model includes:

[0006] The bag body includes two first composite components stacked on top of each other. Each first composite component includes a top edge portion and a peripheral edge portion connected to the top edge portion. The peripheral edge portions of the two first composite components are heat-pressed and bonded to each other so that the two top edges portion together define the urine collection port of the bag body, and the two first composite components together define a liquid-containing cavity communicating with the urine collection port. The first composite component includes an inner composite layer and an outer protective layer stacked on top of each other.

[0007] In one embodiment, the peripheral edge portion includes a bottom strip segment and two side strip segments, with the same side of the two side strip segments respectively connected to the top edge portion, and the opposite sides of the two side strip segments respectively connected to the bottom strip segment; It also includes a second composite component, which is folded in half to form a first support piece and a second support piece. The edge of the first support piece is heat-pressed and bonded to the bottom strip segment and two side strip segments of one of the composite components, and the edge of the second support piece is heat-pressed and bonded to the bottom strip segment and two side strip segments of the other composite component, so that when the first support piece and the second support piece are set at an angle, the bag body can stand upright on a horizontal surface.

[0008] In one embodiment, the peripheral edge includes an outer edge and an inner edge, and the distance between the outer edge and the inner edge is greater than or equal to 4 mm and less than or equal to 10 mm.

[0009] In one embodiment, both the first composite and the second composite are made of biodegradable materials.

[0010] In one embodiment, the outer protective layer is kraft paper; and / or, the inner composite layer is a PET-PE composite film.

[0011] In one embodiment, the bag body is provided with a gripping structure, and the gripping structure is located close to the urine collection port.

[0012] In one embodiment, the gripping structure includes a hanging opening provided in the bag body for fingers to pass through; and / or, the gripping structure includes a contoured groove provided at the edge of the bag body for accommodating fingers.

[0013] In one embodiment, an adhesive sealing component is further included, which is heat-pressed onto the urine collection port and is used to seal the urine collection port.

[0014] In one embodiment, the adhesive sealing assembly includes a first sealing strip and a second sealing strip, wherein the second sealing strip is disposed on the side of the first sealing strip away from the urine collection port.

[0015] In one embodiment, a flow guide sleeve is also included, which is disposed at the urine collection port and partially exposed outside the bag.

[0016] Compared with the prior art, the beneficial effects of the urine bag provided by this utility model embodiment are: the urine bag not only has strong protective performance, but also has good overall structural strength, which can greatly reduce the risk of breakage and leakage during use.

[0017] Specifically, firstly, the bag body is made of a first composite component, which consists of an inner composite layer and an outer protective layer stacked together. Compared to a plastic film structure, this double-layer design not only improves the overall structural strength of the bag body, but also effectively protects the inner composite layer from external friction or damage from sharp objects through the outer protective layer, thereby significantly reducing the risk of leakage and extending its service life.

[0018] Secondly, the bag body adopts a double first composite component overlapping design, and forms a closed edge sealing structure by hot pressing the periphery. The periphery setting can isolate the outer surface of the sealing edge from the inner wall of the liquid cavity. The periphery has better structural strength when under stress and is not easy to scratch and break, which significantly improves the scratch resistance of the edge of the bag body.

Detailed Implementation

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] This utility model embodiment provides a urine bag 1000, such as Figure 1 - Figure 3 As shown, the urine bag 1000 includes a bag body 100, which includes two first composite members 10 stacked on top of each other. Each first composite member 10 includes a top edge portion 11 and a peripheral edge portion 12 connected to the top edge portion 11. The peripheral edge portions 12 of the two first composite members 10 are heat-pressed together so that the two top edges 11 together define the urine collection port 30 of the bag body 100, and the two first composite members 10 together define a liquid-containing cavity communicating with the urine collection port 30. The first composite member 10 includes an inner composite layer 13 and an outer protective layer 14 stacked on top of each other. This application solves the problem in the prior art where the urine bag 1000 is easily damaged and leaks after being scratched. This urine bag 1000 not only has strong protective performance but also good overall structural strength, which can significantly reduce the risk of damage and leakage during use.

[0023] Specifically, firstly, the bag body 100 is made of a first composite component 10, which is composed of an inner composite layer 13 and an outer protective layer 14 stacked together. Compared with the plastic film structure, this double-layer design not only improves the overall structural strength of the bag body 100, but also effectively protects the inner composite layer 13 from external friction or damage from sharp objects through the outer protective layer 14, thereby significantly reducing the risk of leakage and extending its service life.

[0024] Secondly, the bag body 100 adopts a double first composite component 10 overlapping design, and forms a closed edge sealing structure by hot pressing the peripheral edge portion 12. The peripheral edge portion 12 can isolate the outer surface of the double first composite component 10 at the sealing edge from the inner wall of the liquid cavity. The peripheral edge portion 12 has better structural strength when under force and is not easy to scratch and break, which significantly improves the scratch resistance of the edge of the bag body 100.

[0025] In one embodiment, the peripheral edge portion 12 includes a bottom strip segment 121 and two side strip segments 122. The same side of the two side strip segments 122 is connected to the top edge portion 11, and the opposite sides of the two side strip segments 122 are connected to the bottom strip segment 121. The bag body 100 also includes a second composite component 20. The second composite component 20 is folded to form a first support piece 21 and a second support piece 22. The edge of the first support piece 21 is heat-pressed and bonded to the bottom strip segment 121 and the two side strip segments 122 of one of the composite components. The edge of the second support piece 22 is heat-pressed and bonded to the bottom strip segment 121 and the two side strip segments 122 of the other composite component, so that when the first support piece 21 and the second support piece 22 are set at an angle, the bag body 100 can stand upright on the horizontal surface. With this configuration, the second composite component 20 allows the bag body 100 to stand upright on a horizontal plane, making it more convenient for users to store and place the urine bag 1000 after use. The uprightness of the bag body 100 is achieved by the first support piece 21 and the second support piece 22 forming a certain angle. The first support piece 21 and the second support piece 22 can form a stable triangular support structure for the bag body 100. Even when the liquid volume in the urine bag 1000 is small, the bag body 100 can maintain a stable upright state and is not easily tipped over by external forces.

[0026] In one embodiment, the peripheral edge portion 12 includes an outer edge 123 and an inner edge 124, the distance between the outer edge 123 and the inner edge 124 being greater than or equal to 4 mm and less than or equal to 10 mm. This configuration facilitates edge sealing processing by controlling the width of the peripheral edge portion 12, while effectively ensuring the structural strength of the peripheral edge portion 12, making the peripheral edge portion 12 less prone to damage.

[0027] Preferably, in this application, the distance between the outer edge 123 and the inner edge 124 is 7 mm.

[0028] In one embodiment, both the first composite component 10 and the second composite component 20 are made of biodegradable materials. This arrangement ensures that the urine bag 1000 is made of environmentally friendly materials, which is more in line with environmental regulations and trends, reduces environmental pollution, and allows the biodegradable urine bag 1000 to decompose more quickly after disposal, reducing the burden of landfill or incineration, lowering treatment costs and long-term environmental risks, effectively reducing resource consumption, promoting sustainable development, and enabling the urine bag 1000 to balance functionality and environmental protection.

[0029] In one embodiment, the outer protective layer 14 is kraft paper; and / or, the inner composite layer 13 is a PET-PE composite film.

[0030] Specifically, the PET-PE composite film includes a PET film and a PE film. The inner composite layer 13 is made of PET film and PE film stacked together, so that the outer protective layer 14, PET film and PE film of the first composite component 10 are stacked from the outside to the inside. In this way, the first composite component 10 of the urine bag 1000 has three layers of protection, which has better protective performance. The composite film is made of PET film and PE film. PET film has low gas and moisture permeability and has excellent barrier properties, which can effectively block gas, moisture, oil and odor. PE film has good chemical stability and can resist the erosion of most acids, alkalis, organic solutions and high-temperature liquids. It also has good insulation and tensile strength, which can further improve the overall performance of the urine bag 1000.

[0031] In one embodiment, the bag body 100 is provided with a grip structure 40, and the grip structure 40 is located near the urine collection port 30. This arrangement makes it easy for the user to pick up the urine bag 1000 and prevents the urine bag 1000 from slipping out of their hand.

[0032] There are many ways to configure the grip structure 40. In one embodiment, the grip structure 40 includes a hanging opening 41 on the bag body 100 for an external component to pass through; the external component can be a hand or a hook, etc. Thus, the user can suspend or hold the urine bag 1000 through the hanging opening 41, for example, by placing the hanging opening 41 on a hook or by passing four fingers through the hanging opening 41 to better grip the urine bag 1000, so that the user can adjust the position of the urine bag 1000 during urination and reduce the risk of the urine bag 1000 accidentally slipping. In another embodiment, the grip structure 40 includes a contoured groove 42 at the edge of the bag body 100, which is used to accommodate fingers. Thus, the user's fingers can be accommodated in the contoured groove 42 to grip the urine bag 1000, reducing the risk of the urine bag 1000 accidentally slipping during urination. In Embodiment 3, which combines Embodiment 1 and Embodiment 2, the hanging opening 41 and the contoured groove 42 are spaced apart in the width direction of the urine bag 1000. In this way, the user can better hold the urine bag 1000 by using the hanging opening 41 and the contoured groove 42. For example, the user can put his thumb through the hanging opening 41 and place his four fingers in the contoured groove 42 to hold the urine bag 1000, so as to further reduce the risk of the urine bag 1000 accidentally slipping off during urination.

[0033] In one embodiment, the urine bag 1000 further includes an adhesive sealing component 200, which is heat-pressed onto the urine collection port 30 and used to seal the urine collection port 30. With this configuration, the adhesive sealing component 200 can seal the urine collection port 30 after the urine bag 1000 has collected liquid, thereby completely eliminating the risk of accidental leakage of liquid from the urine collection port 30 after use. Furthermore, since the adhesive sealing component 200 can also seal the liquid-containing cavity, it can prevent the odor of the liquid in the cavity from spreading to the external environment, ensuring hygiene and improving the user experience.

[0034] Preferably, the adhesive sealing assembly 200 includes a first sealing strip 210 and a second sealing strip 220, with the second sealing strip 220 disposed on the side of the first sealing strip 210 away from the urine collection port 30. Thus, the adhesive sealing assembly 200 employs a double-seal configuration of the first sealing strip 210 and the second sealing strip 220. Even if the first sealing strip 210 is not completely closed, the second sealing strip 220 still provides protection, further improving the sealing performance and effectively enhancing safety during use.

[0035] Similarly, the adhesive sealing assembly 200, the first composite 10, and the second composite 20 are also made of biodegradable materials.

[0036] Reference Figure 4In one embodiment, the urine bag 1000 further includes a flow guide sleeve 300, which is installed at the urine collection port 30 and partially exposed outside the bag body 100. Thus, the flow guide sleeve 300 can cover the urinary organ to reduce liquid splashing outside the urine bag 1000 during urination, ensuring that liquid can only flow into the liquid-containing cavity from the urine collection port 30, preventing leakage during use.

[0037] Specifically, the flow guide sleeve 300 is made of biodegradable materials. For example, the flow guide sleeve 300 can be made of biodegradable foam, which combines high barrier properties with environmental friendliness and soft texture, thus avoiding discomfort to the user's skin when in contact with the skin.

[0038] Preferably, the side of the diversion sleeve 300 away from the bag body 100 is provided with an arc-shaped surface 310, which is convenient for female users. The arc-shaped surface 310 can fit the skin better and ensure that leakage will not occur.

[0039] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
