The squeezed urine collection bottle (6) is then connected to the urinary stoma bag (1) by the hose (5), thereby forming a system which is in fluid communication and sealed from the environment.

Description

Technical Field

[0001] This utility model relates to a urine collection device. Background Technology

[0002] Various urine collection devices have been disclosed in the prior art. International patent application publication numbers WO2006044249 and WO2012118643, as well as Chinese utility model publication numbers CN211246116U, CN211750679U and CN213697005U, disclose some urine collection devices.

[0003] Chinese utility model publications CN209316203U, CN209713782U, CN209967195U, and CN215273744U disclose systems utilizing urostomy bags. One of the biggest drawbacks of these systems is their complexity. They include additional pump systems and / or complex valve systems. These additional components not only complicate the use of the device but also increase the end-user's expenses or costs.

[0004] The aforementioned urine collection device does not provide a safe and reliable urine discharge for users sleeping in bed at night. It is common for users of urostomy bags to accidentally compress the bag while sleeping, potentially leading to urine leakage.

[0005] The purpose of this invention is to avoid the complexity of the aforementioned prior art. Furthermore, the purpose of this invention is to create a urine collection device that users can use while sleeping in bed at night without worrying about urine leakage onto the bed due to squeezing the urostomy bag. Utility Model Content

[0006] The purpose of this invention is to design a urine collection device, which includes the following components: a urethral bag, a urine collection bottle, and a tubing connecting the urethral bag and the urine collection bottle.

[0007] The urostomy bag includes a urostomy bag opening for receiving urine from a point or passage in the body for urination. The urostomy bag also includes a urine outlet opening for draining urine from the urostomy bag. The urine outlet opening is equipped with a valve to allow the urostomy bag to be closed or opened to drain urine. This valve may be a manually operated shut-off valve. Any commercially available urostomy bag or any urostomy bag known to a technician may be used as this urostomy bag.

[0008] The tubing includes a first end and a second end, wherein the first end of the tubing is connectable to the opening of the urostomy bag, and the second end of the tubing is connectable to the urine collection bottle. Any commercially available or medical tubing known to a technician can be used as the tubing.

[0009] The focus of this invention is a specially configured urine collection bottle that can generate negative pressure or a dilute state within the urine collection device, thereby safely delivering urine discharged from the urostomy bag to the collection bottle without causing urine backflow or excessive accumulation of urine in the urostomy bag at night (when the user of the urine collection device is asleep). The urine collection bottle includes an orifice configured to connect to a second end of the tubing in such a way that a sealed fluid communication is provided between the urostomy bag and the urine collection bottle. The urine collection bottle also includes a corrugated wall formed to make the urine collection bottle compressible, thereby reducing its volume. The corrugated wall is formed such that when the pressure between the urine collection device and the surrounding environment is equalized, it can restore the urine collection bottle to its initial volume or state. Therefore, the corrugations in the corrugated wall should be formed to allow the urine collection bottle to be compressed, returning it to its initial state, thereby compensating for the amount of urine entering.

[0010] When the squeezed urine collection bottle is connected to the urostomy bag through the tubing, and the urostomy bag is connected to the urine collection point or channel of the human body or patient, the entire device or system is in a sealed fluid communication state and isolated from the surrounding environment.

[0011] A urine collection bottle with an orifice is configured to connect to a urostomy bag via a tubing, thereby establishing a sealed fluid communication between the urostomy bag and the urine collection bottle. The urine collection bottle is characterized by including a corrugated wall formed to make it compressible, thus reducing its volume. The corrugated wall is configured to allow the urine collection bottle to return to its initial volume or state when the pressure between the urine collection device and the surrounding environment is equalized. The compressed urine collection bottle connected to the urostomy bag via the tubing creates a negative pressure within the compressed urine collection bottle, the urostomy bag, and the tubing, thereby transferring urine released by the user of the device from the urostomy bag to the compressed urine collection bottle via the tubing. Therefore, no urine is stored in the urostomy bag, and accidental release of urine from the urostomy bag is prevented. As the user of the device gradually releases urine, the compressed urine collection bottle gradually returns to its initial shape.

[0012] The volume of the urine collection bottle in its uncompressed state can be between 2 and 3.5 liters, preferably about 2.7 liters. The volume of the urine collection bottle in its compressed state can be between 1 and 1.9 liters, preferably about 1.5 liters. Approximately a doubling of the volume is sufficient to ensure that the pressure within the urine collection device is significantly lower than the ambient pressure, thereby allowing urine contained in the urostomy bag to be delivered to the urine collection bottle. Analogous to almost all known nocturnal urine collection systems, the urine collection bottle should be positioned below the user's sleep level (i.e., relative to the sleeping area).

[0013] In one embodiment of this invention, the orifice of the urine collection bottle and the second end of the tubing include threaded connections, allowing the second end of the tubing to be screwed into the orifice of the urine collection bottle, thus completely isolating the urine collection bottle from the surrounding environment. The device includes a cap attached to the second end of the tubing and adapted to be screwed into the orifice of the urine collection bottle. This threaded cap is particularly useful because it can be slightly opened before squeezing the urine collection bottle, thereby releasing excess air. By subsequently tightening the cap, a negative pressure or dilute state is maintained within the urine collection bottle of the device, thereby allowing urine to be collected from the urostomy bag or transferred into the urine collection bottle.

[0014] The objective of this invention is also achieved through the aforementioned method of using the urine collection device. The method includes the following steps: (I) squeezing the urine collection bottle through the corrugated wall of the bottle; (II) connecting the squeezed urine collection bottle to the urostomy bag via the tubing, thereby forming a fluid connection and environmental sealing system between the urostomy bag, the tubing, and the urine collection bottle, and maintaining the air pressure in the urine collection bottle, the tubing, and the urostomy bag below the ambient air pressure. In this state, urine released by the user is immediately transferred from the urostomy bag, where there is a risk of accidental urine release, to the urine collection bottle, where the urine is safely stored away from the user. Safety is maintained through remote positioning of the urine collection bottle provided by the tubing.

[0015] The method further includes the following steps: (III) keeping the valve of the urethral bag closed when the squeezed urine collection bottle is connected to the urethral bag through the tubing; and (IV) opening the valve of the urethral bag when the squeezed urine collection bottle is connected to the urethral bag through the tubing, thereby keeping the air pressure in the urine collection bottle, the tubing and the urethral bag lower than the ambient air pressure.

[0016] In another embodiment of the present invention, the step of connecting the squeezed urine collection bottle to the urostomy bag via the tubing is achieved by screwing the cap of the tubing into the bottle hole of the squeezed urine collection bottle. Attached Figure Description

[0017] The accompanying drawings illustrate various embodiments of the present invention by way of example, all of which fall within the scope of the invention as defined by the claims.

[0018] Figure 1 This is a schematic diagram of a urine collection device.

[0019] Figure 2 An embodiment of a urine collection bottle (6) is shown. Detailed Implementation

[0020] Embodiments of the present invention will now be described with reference to the accompanying drawings to illustrate the objectives, advantages, and effectiveness of the present invention.

[0021] like Figure 1The urine collection device shown includes a urethral bag (1). The urethral bag (1) includes a urethral bag opening (2) for receiving urine from a user or patient, and a urine outlet opening for draining urine from the urethral bag (1). The urine outlet opening is also provided with a manually rotatable shut-off valve (4) for closing or opening the urethral bag (1). The device includes a tubing (5) having a first end and a second end. The first end of the tubing (5) is connected to the urine outlet opening of the urethral bag (1). The device includes a urine collection bottle (6) having a bottle hole (7). The bottle hole (7) of the urine collection bottle (6) is formed to connect to the second end of the tubing (5), thereby providing a sealed fluid communication between the urethral bag (1) and the urine collection bottle (6). In this embodiment of the present invention, the bottle hole (7) of the urine collection bottle (6) and the second end of the hose (5) include threaded connectors, allowing the second end of the hose (5) to be screwed into the hole (7) of the urine collection bottle (6), completely isolating or sealing the urine collection bottle (6) from the surrounding environment. The threaded connector implemented by the device includes a cap (8) attached to the second end of the hose (5) and adapted to be screwed into the bottle hole (7) of the urine collection bottle (6). The bottle hole (7) itself has threads that are adapted to the threads of the cap (8). The urine collection bottle (6) itself includes a corrugated wall (9) formed such that the urine collection bottle (6) is compressible, thereby reducing its volume, wherein the corrugated wall (9) is formed such that when the pressure between the urine collection device and the surrounding environment is equal, it enables the urine collection bottle (6) to return to its initial volume or state. These components are connected during use to form a closed urine collection environment with negative pressure. As can be seen in this example, the urethral bag (1) and urine collection bottle (6) are separate from the tubing (5) before use. During use, the urine collection bottle (6) is squeezed and attached to the tubing (5) in this squeezeable state, thereby creating negative pressure within the urethral bag (1), tubing (5), and urine collection bottle (6). The negative pressure generated within the system allows urine released by the patient or user to be forcibly transferred from the urethral bag (1) to the urine collection device (6).

[0022] Figure 2An embodiment of a urine collection bottle (6) is shown. The urine collection bottle (6) includes a bottle hole (7), which is the only outlet to the surrounding environment when the urine collection bottle (6) is not in use. During use, the bottle hole (7) is in fluid communication with a urostomy bag (1) via a hose (5). The hole (7) is closed by a cap (8) via its threaded connection. The cap (8) itself has a hole for attaching the hose (5). In this embodiment of the invention, the urine collection bottle (6) has dimensions in which the height of the urine collection bottle (6) is 179 mm, however, the height of the bottle with the threaded connection of the bottle hole (7) is 201 mm. Furthermore, in this embodiment, the corrugated wall (9) of the urine collection bottle (6) includes four ridges or four protrusions, and five recesses between the four ridges or four protrusions, wherein the width of the recesses is 11 mm. The diameter of the urine collection bottle (6) is 170 mm; however, the diameter of the bottle (6) between the recesses of the corrugated wall (9) is 121 mm. The volume of this urine collection bottle (6) in its uncompressed state is approximately 2.7 liters, but in its compressed state it is approximately 1.5 liters.
